7.Description:
(en)BACKGROUND
The need to improve efficiency is an omnipresent goal within the package delivery industry. Package volume grows each year, along with customer requirements for greater package tracking and faster delivery. This presents an ongoing challenge to shippers throughout the country, who continuously work to streamline all stages of the package transportation process, from sortation and loading, to routing and delivery.
Carriers typically maintain delivery data for each of the shipments that are forecasted to be delivered by a delivery network. This dynamic data may include a ship date, an origin address, destination address, service level, a forecasted delivery date, a unique identifier (e.g., a tracking number), and exception information. As a package moves through the delivery network, the unique identifier is captured and location information related to the shipment is updated in the associated delivery data record. This delivery record may be accessed using the unique identifier to review the data.
In general, carriers generate a dispatch plan which is the schedule or route through which a carrier assigns work to carrier service providers (such as delivery vehicle drivers) to coordinate and schedule the pickup and delivery of packages. Dispatch plans are well known in the carrier industry and are used daily by commercial carriers to manage driver delivery routes. Once assigned to a vehicle, the packages are routed through the carrier's destination facility to the appropriate vehicle to be loaded thereon.
Typically, a carrier destination facility has a plurality of package cars that are being loaded simultaneously and each package car has a variety of potential storage locations. Loading personnel have the responsibility of ensuring that the packages are loaded in the correct position within a vehicle. An unsatisfied need exists in the industry for improved systems and methods for loading packages.
SUMMARY
The present invention provides systems, methods, and apparatuses for automated loading and unloading of items in delivery vehicles. In one aspect of the invention, a method of loading items into a vehicle is provided. The method includes the steps of: capturing shipping indicia associated with an item, wherein the shipping data includes a destination address or a unique identifier; determining a storage location within the vehicle for the item; disposing the item into the vehicle via an access port; and activating a load/unload device to move the item to the storage location within the vehicle.
In another aspect of the invention, a system for loading an item is provided. The system includes a vehicle having a cargo area with an access port, and a plurality of storage locations, wherein at least some of the storage locations have restrictions relating to the items that can be stored therein; a load/unload device configured to transport an item from the access port to one of the plurality of storage locations; and a controller disposed within the vehicle and comprising at least one processor and at least one memory having program code instructions embodied therein. The memory and program code instructions are configured to, with the at least one processor, cause the controller to: determine a storage location for the item; and provide instructions to the load/unload device indicating the storage for the item.

II. EXEMPLARY SYSTEM ARCHITECTURE
A. System Overview
FIG. 1 illustrates an overview of a system 10 configured to load items according to an example embodiment. It should be understood that the system depicted in FIG. 1 is merely one example configuration of a system for loading items and that many other configurations are possible. As illustrated, the exemplary system 10 may include one or more conveying systems 5 , one or more loading stations 30 , once or more carrier systems 100 , one or more mobile computing entities 105 , and one or more delivery vehicles 400 . The loading stations 30 may include a data capture device 32 , a user interface 34 and a label printer (not shown). In addition, the one or more carrier systems 100 may receive information from the data capture devices for tracking and other purposes. In addition, the one or more carrier systems 100 may also provide handling instructions regarding the appropriate delivery vehicle 40 and storage location for placement of a particular item. Various components of the system may communicate via network 90 .
As will be recognized, an item 2 may be a parcel or group of parcels, a package or group of packages, scrap metal banded together, a vehicle part, a box, a crate, a drum, a box strapped to a pallet, and/or the like. In one embodiment, each item may include an item/shipment identifier, such as a barcode, a MaxiCode, electronic representation, and/or text (e.g., alphanumeric text). The unique item/shipment identifier (e.g., 123456789) may be used by the carrier to identify and track the item as it moves through the carrier's transportation network. Such item/shipment identifiers can be affixed to items by, for example, using a sticker (e.g., label) with the unique item/shipment identifier printed thereon (in human and/or machine readable form) or an RFID tag with the unique item/shipment identifier stored therein. In addition to the item/shipment identifier, the label or RFID tag may also include other shipping information such as a destination address which may also be captured.
Generally described, items are received at a loading station 30 where identification data may be captured for each item and handling instructions may be generated. In some embodiments, a label having indicia associated with the item may be generated and affixed to the item. The items may then be deposited through an access door into the vehicle identified in the handling instructions. Once the items are loaded into the access door, an automated load/unload device may deposit the item in the appropriate storage location. Provided below is a more detailed discussion of aspects of various embodiments.
B. Exemplary Conveying System
The conveying system 5 may be any device or accumulation of devices for moving items. For example, the conveying system 5 could be a series of belts, conveyors, and/or shoots that divert items from a sorting and/or receiving location to a loading station 30 . Other embodiments may include moving a plurality of items in batches via pallets, boxes, bins or other devices. For example, items may be consolidated based on a variety of criteria, for example, destination addresses within a threshold area, assignment to (1) the same delivery vehicle, (2) the same loading station, (3) the same shelf in the vehicle 400 , and the like. The consolidation may occur at the loading station 30 or at upstream processes with the items being disposed into a container. Thus, the items would be processed as a group as opposed to being processed individually (e.g., sorted, moved to a loading station, loaded into the vehicle via the access door, deposited automatically deposited at the appropriate storage location, etc.). In various embodiments, items bound for a particular neighborhood, apartment complex, shopping center and the like may be consolidated into a single container. As used herein, the terms “item” and “container of items” are interchangeable.
C. Exemplary Loading Stations
Items received at a facility may be conveyed by the conveying system 5 to one or more loading stations 30 . In various embodiments, the loading station 30 includes a data capture device 32 , a user interface 34 , a printer (not shown) and/or a mobile computing entity 105 . The mobile computing entity 105 may include a data capture device and a user interface. The data capture device 32 may be a barcode or MaxiCode scanning device, an RFID interrogator, a camera, or other data capture device.
The data capture device 32 , user interface 34 , printer, mobile computing entity 105 and one or more carrier systems 100 may be in electronic communication with, for example, one another over the network 90 which may be the same or different wireless or wired networks including, for example, a wired or wireless Personal Area Network (PAN), Local Area Network (LAN), Metropolitan Area Network (MAN), Wide Area Network (WAN), or the like.
In various embodiments, the user interface 34 (and/or mobile computing entity 105 ) may include a display device/input device for receiving and displaying data may also be included in or associated with the carrier system 100 . The display device/input device may be, for example, a keyboard or pointing device that is used in combination with a monitor.
In one embodiment, the data capture device 32 (and/or mobile computing entity 105 ) scans or reads the item/shipment identifier and other appropriate information (e.g., location and time of the scan or reading) and communicates the information to the one or more carrier systems 100 .
Using the captured information, the one or more carrier systems 100 provides handling instructions to the loading personnel via the user interface 34 and/or mobile computing entity 105 . As will be discussed in greater detail below, the handling instructions may include a vehicle identifier and a storage location identifier.
In some embodiments, an item may be received at a loading station 30 with a label having human-readable and or machine-readable indicia providing handling instructions. In this case, the loading personnel may follow the handing instructions and load the items into the appropriate vehicle accordingly (e.g., a label applied upstream of the loading station 30 ). In further embodiments, the data capture device 32 (and/or mobile computing entity 105 ) may scan/read machine-readable indicia from the label to retrieve the instructions (e.g., a label applied at the receiving station, a shipping label, etc.). In this case, the instructions may be communicated to the loading personnel via the user interface 34 (and/or mobile computing entity 105 ).
Moreover, in various embodiments, the loading station 30 may comprise an item buffer configured to store one or more items after being received at the loading station but before being loaded into an appropriate vehicle. Thus, such item buffer may accommodate a plurality of items received by the loading station 30 in rapid succession such that the items are not loaded into an appropriate vehicle before a subsequent item is received.

FIGS. 5 and 6 illustrate an exemplary delivery vehicle 400 . In the illustrated embodiment, the cargo area 410 comprises an access port 415 , a bulkhead 417 separating a driver area from the cargo area 410 , a driver side wall 420 and a passenger side wall 430 . The cargo area 410 includes a plurality of storage locations configured to receive items for transport. The storage areas may include one or more bins, shelves and/or the like configured to store items. The illustrated embodiment includes 12 shelves (six on each side of the cargo area 410 ) but other embodiments may include more or less shelves/bins.
In various embodiments, the storage locations may comprise rollers, powered rollers, conveyor belts or the like that are configured to bias items toward the outer wall of the vehicle 400 and/or towards the center of the vehicle 400 . These devices may be selectively activated by the controller 140 to either position items toward the outer wall of the vehicle 400 and/or towards the center of the vehicle 400 as desired.
The vehicle 400 may also be equipped with an automated load/unload device 460 . In various embodiments, the automated load/unload device 460 is configured to capture items and move the item to and from storage locations within the vehicle 400 . In one embodiment, the automated load/unload device 460 comprises a turntable robot that includes a platform 462 configured to receive an item operatively connected to a base 464 .

These architectures are provided for exemplary purposes only and are not limiting to the various embodiments.
III. EXEMPLARY METHODS OF OPERATION
Having thus provided an overview of components which may be included in a system for loading/unloading items according to various embodiments, attention is now directed to FIGS. 7-11 , which depict steps that may be performed in accordance with various embodiments.
A. Depositing Items into Vehicles Based on Delivery Sequence
FIG. 7 illustrates steps that may be performed in accordance with various embodiments to assign and load items onto a vehicle 400 . The process begins at Block 600 where an item is received at a loading station 30 . At Block 610 , the associated shipping indicia are captured. In various embodiments, the shipping indicia include item/shipment identifier and/or destination address information. The captured shipping indicia are transmitted to the one or more carrier systems 100 . The one or more carrier systems 100 identify destination information (either captured or determined using the item/shipment identifier) and compare the destination address against a dispatch plan to determine which route/vehicle is assigned to deliver to the destination address at Step 620 . In some embodiments, the destination address may be captured and sent to the one or more carrier systems 100 in addition to or in place of the item/shipment unique identifier.
After identifying the route/vehicle, the one or more carrier systems 100 may then generate a handling instruction identifying the appropriate route/vehicle and a storage location on the vehicle for the item at Block 630 . To identify the appropriate storage location, the one or more carrier systems 100 may divide the route according to the number of shelving units assigned to the route. Assuming the vehicle has 12 shelves, the route would be divided into twelve sequential segments. Items to be delivered during the first segment may be assigned, for example, to a particular shelf for the route (e.g., top Forward Driver-side location) and items assigned to the second sequential segment may be assigned to a second shelf (e.g., middle Forward Driver-side location). The associated item IDs would then be linked or otherwise associated with the appropriate shelf location by the one or more carrier systems 100 . The sequential segments may be similarly divided by the number of storage locations on the shelf. The one or more carrier systems 100 may assign the items to the storage location according to the order in which they may be delivered. The shelves may have dividers separating the different storage locations.
In various embodiments, the handing instructions may be communicated via a label at Step 650 . The handling instruction may be communicated via a label generated and affixed to the item, an instruction provided on the mobile computing entity 105 , a visual indicator proximate the appropriate vehicle (e.g., a light) or the like. In one embodiment, the label may be generated at the loading station 30 or in an upstream process. The label may include indicia communicating the vehicle ID, the shelf and/or a storage location. Other information on the label may include a package tracking number, primary and secondary package sortation information, a commit time and an irregular drop-off indicator.
In one embodiment, an order is set in a dispatch plan and takes into account the direction a driver will be delivering for a particular street range. The commit time indicator on the label may indicate when a package is committed for delivery at a particular time. The commit time may be based on the service level desired by the customer, such as for example Next Day Air, Second Day Air or Ground. The irregular drop-off indicator on the label may indicate the location in the facility where irregular items are sorted manually. Irregular items are typically too large or too heavy or shaped in such a way that they cannot be placed on a sortation belt. A more detailed discussion of possible loading schemes that could be used for a shelf is described in U.S. Pat. No. 8,068,930, which is incorporated by reference herein in its entirety.
At Block 660 , a loading operator retrieves the item from the conveying system 5 and deposits the item into the appropriate vehicle 400 via the vehicle access port 415 . In some embodiments, the item is placed directly onto a platform of the automated load/unload device 460 inside the vehicle 400 (e.g., including an item buffer). In other embodiments, the item may be placed on a separate platform or conveyor that positions the item within reach of the automated load/unload device 460 (e.g., including an item buffer).
At Block 670 , the appropriate storage location is determined and communicated to/captured by the controller 140 . In some embodiments, the vehicle 400 includes a data capture device 450 which captures indicia from the item. The indicia may include the handling instruction, the unique identifier for the item, a destination address, and/or other information. Using this captured information, the controller 140 identifies (by itself or in conjunction with the carrier system 100 ) where the item is to be positioned. In some embodiments, the controller 140 communicates with the data capture device 32 and/or the mobile computing entity 105 at the loading station 30 and receives the storage location identification as opposed to using information captured by data capture device 450 . In this embodiment, the controller recognizes when the item is placed into the vehicle via a light curtain, proximity switch on the platform or the automated load/unload device 460 and then associates the received storage location with the item.
After acquiring the storage location, the controller 140 sends an actuation signal to the automated load/unload device 460 to position the item onto the appropriate storage location. For example, if the captured indicia include the handling instructions with a storage location identifier, the controller 140 will send a signal to the automated load/unload device 460 to move to the appropriate location (i.e. fore/aft to the appropriate location and up/down relative to the appropriate storage location) and deposit the item at the appropriate location. In some embodiments, the controller 140 will also send a signal to the appropriate storage location to initiate movement of the associated power rollers/conveyors to receive the item and bias the item against the associated side wall of the vehicle 400 . In various embodiments, the controller 140 stores the location of the item in memory for later retrieval when the item is to be delivered. After positioning the item onto the appropriate location, the automated load/unload device 460 may return to its home position, ready to position an additional item. In various embodiments, the
B. Depositing Items into Vehicles Based on Item Characteristics
In a further embodiment, the loading scheme may be based on characteristics of the item as opposed to the sequence of delivery of the item. Similar to previous embodiments, the process begins at Block 700 in FIG. 8 where an item is received at a loading station 30 (e.g., including an item buffer). At Block 710 , the associated shipping indicia are captured. In various embodiments, the shipping indicia may include item/shipment identifier and/or destination address information. The captured shipping indicia are transmitted to the one or more carrier systems 100 . The one or more carrier systems 100 identifies destination information (either captured or determined using the item/shipment identifier) and compares the destination address against a dispatch plan to determine which route/vehicle is assigned to deliver to the destination address at Step 720 . In some embodiments, the destination address may be captured and sent to the one or more carrier systems 100 in addition to or in place of the item/shipment unique identifier.
After identifying the route/vehicle, the one or more carrier systems 100 may then generate a handling instruction identifying the appropriate route/vehicle at Block 730 which is then communicated to the load personnel at Block 740 . The handling instruction may be communicated via a label generated and affixed to the item, an instruction provide on the mobile computing entity 105 , a visual indicator proximate the appropriate vehicle (e.g., a light) or the like.
At Block 750 , the load personnel deposit the item into the identified vehicle 400 via the vehicle access port 415 (e.g., including an item buffer). In some embodiments, the item is placed directly onto a platform of the automated load/unload device inside the vehicle 400 . In other embodiments, the item may be placed on a separate platform or conveyor that positions the item within reach of the automated load/unload device 460 .
At Block 760 , the controller 140 determines characteristics of the item. In some embodiments, a data capture device 450 associated with the vehicle 400 captures indicia from the item. The indicia may include identification of characteristics of the items (e.g., dimensions, weight, fragile, etc.). In other embodiments, the data capture device 450 captures a unique identifier associated with the item which is communicated to the controller 140 . The controller 140 then communicates with the carrier systems 100 to obtain characteristics of the item that may be stored in a record associated with the captured indicia. In some embodiments, characteristic of the items bound for the particular vehicle may be downloaded to the controller 140 prior to loading items, in which case the controller 140 may determine characteristics of the item without further communication with the carrier systems 100 . In further embodiments, the vehicle 400 may include a dimensioning device and/or weighing device to determine characteristics of the item independently. In some embodiments, characteristics are obtained from multiple sources (e.g., stored record, captured from label, and/or independently measured).
After the characteristics are acquired, the controller 140 determines where to deposit the item in the vehicle at Block 770 . In various embodiments, the cargo area 410 within the vehicle 400 may be configured to store items of particular sizes/weights in particular locations. For example, some vehicles 400 may be configured with multiple storage locations to accommodate items of a predetermined threshold sizes (e.g., one or more dividers for each shelf, separate conveyors, and the like to separate items). For example, a vehicle may comprise storage locations configured to store small, medium, large items where each category of item size has an associated size threshold. In some embodiments, the cargo area 410 may include an area to accommodate irregular items that would not fit within the threshold sizes. The handling instruction may identify the storage location and/or the loading characteristics of the item (e.g., weight, dimensions, etc.)
In various embodiments, the controller 140 and/or the carrier systems 100 compares the acquired characteristics against the threshold parameters for storage locations to determine which storage locations could accommodate a particular item. The controller and/or carrier systems 100 also identifies storage locations having capacity to receive the item. In various embodiments, the controller 140 and/or carrier systems 100 monitors where items are placed and can therefore identify which storage locations are available. In some embodiments, the storage locations themselves have monitoring devices to indicate whether an item is present (e.g., proximity switches, light curtains, and the like and communicate their status to the controller 140 .
After an available storage location is identified for the item, the controller 140 sends an actuation signal to the automated load/unload device 460 to position the item onto the storage location. For example, if the captured indicia include the handling instructions with a storage location identifier, the controller 140 will send a signal to the automated load/unload device to move to the appropriate location (i.e. fore/aft to the appropriate location and up/down relative to the appropriate location) and deposit the item onto the appropriate location. In some embodiments, the controller 140 will also send a signal to the appropriate storage location to initiate movement of the associated power rollers/conveyors to receive the item and bias the item against the associated side wall of the vehicle. In various embodiments, the controller 140 stores the location of the item in memory for later retrieval when the item is to be delivered. After positioning the item onto the appropriate location, the automated load/unload device 460 may return to a home position, ready to position an additional item.
C. Delivering Items
After the loading process is complete, the vehicle will proceed to deliver items according to the assigned route/dispatch plan. FIG. 9 illustrates steps that may be performed in accordance with various embodiments to deliver items. The process begins at Block 800 where the location of the vehicle 400 is monitored. In various embodiments, the vehicle 400 may include telematics devices (e.g. data collection devices 130 ) and/or location-determining devices 120 which monitor the progress of the vehicle 400 as it delivers and picks up items along the assigned route. The progress may be monitored based on the sequence of deliveries (e.g., first schedule delivery complete, second delivery pending, etc.) and/or based on the physical location of the vehicle (e.g., GPS location).
At Block 810 , the controller 140 may determine the next item to be delivered. This determination may be made in a number of different ways. For example, the controller may retain in memory a copy of the dispatch plan indicating the sequence of delivery for the items loaded onto the vehicle 400 . As items are unloaded, the controller 140 may recognize which item is next in the delivery sequence by monitoring which items are retrieved from storage. Alternatively, the controller may communicate with the driver's mobile computing entity and/or the carrier systems 100 to determine the next delivery in the delivery sequence. In this case, mobile computing entity and/or the carrier systems 100 may determine the next item to be delivered based on the location of the vehicle and/or the progress made with respect to the sequence of delivery (e.g., which package was last delivered in the assigned delivery sequence).
At Block 820 , the controller 140 sends instructions to the automated load/unload device to retrieve the next item to be delivered based on a trigger event. In some embodiments, the controller 140 sends the instructions to the automated load/unload device 460 to retrieve the next item following retrieval of an item from the vehicle 400 access port 415 (e.g., a trigger event). In other embodiments, the triggering event may be when the vehicle 400 is within a threshold distance from the delivery location for an item. In some cases, the triggering event may be when the vehicle is stopped at the delivery location and the controller 140 instructs the automated load/unload device to retrieve the item associated with the location. This may be determined by the controller 140 based at least in part on telematics devices (e.g., engine off, parking brake on, seat belt released, etc.), based on location determining devices (e.g., within threshold distance, no movement for threshold time frame, etc.) and/or input from the driver via the driver's mobile computing entity (e.g., driver requesting retrieval of specific item)).
In response to the instructions, the automated load/unload device 460 and/or the associated storage location are activated to obtain the item from the storage location at Block 830 . In some embodiments, the automated load/unload device 460 moves to a position proximate the appropriate storage location (i.e. fore/aft to the appropriate location and up/down relative to the appropriate storage location) and retrieves the item from the storage location. In some embodiments, the controller 140 will also send a signal to the appropriate storage location to initiate movement of associated power rollers/conveyors to urge the item onto a platform of the automated load/unload device 460 (e.g., including an item buffer). In other embodiments, the automated load/unload device 460 grasps the item from the storage location. After the item is obtained by the automated load/unload device 460 , the automated load/unload device 460 transports the item to the vehicle access port 415 at Block 840 (e.g., including an item buffer). At Block 850 , a driver retrieves the item via the vehicle access port and delivers the item to the delivery address.
D. Picking Up Items
In some cases, the driver and/or a shipper has a need to deposit items within the vehicle 400 . For example, a delivery attempt for a particular item may be unsuccessful and/or a customer has a pickup which may be scheduled or unscheduled. In other embodiments, a customer may seek to deposit an item into the vehicle for delivery to a consignee. In further embodiments, a vehicle 400 may be parked at a predetermined location (e.g., parking lot, address, landmark, etc.) for a predetermined time period for the purpose of receiving items for delivery. FIG. 10 illustrates steps that may be performed in picking up and/or receiving items in accordance with an embodiment of the invention. The process may begin at Block 900 where the driver receives the item for placement onto the vehicle (e.g., unsuccessful delivery, customer pickup, shipper drop off). In many cases, the item may already have an assigned unique identifier (e.g., unsuccessful delivery, customer printed shipping label, etc.), and the driver will capture the unique identifier using a mobile computing entity 105 to indicate the item is being placed in the vehicle 400 at Block 910 . In other cases, the driver may enter delivery information or other identifying information into the mobile computing entity 105 , which may be communicated to the controller 140 and/or the carrier systems 100 .
At Block 920 , the item is deposited in the vehicle 400 via the access port 415 (e.g., including an item buffer). In some embodiments, the item is placed directly onto a platform of the automated load/unload device 460 inside the vehicle 400 (e.g., including an item buffer). In other embodiments, the item may be placed on a separate platform or conveyor that positions the item within reach of the automated load/unload device 460 .
At Block 930 , the controller 140 may determine characteristics of the item. In some embodiments, a data capture device 450 associated with the vehicle 400 captures indicia from the item. The indicia may include identification of characteristics of the items (e.g., dimensions, weight, fragile, etc.). In other embodiments, the data capture device 450 captures a unique identifier associated with the item which is communicated to the controller 140 . The controller 140 then communicates with the carrier systems 100 to obtain characteristics of the item that may be stored in a record associated with the captured indicia. In some embodiments, a driver may use a mobile computing entity 105 to capture information concerning the item (e.g., unique identifier, characteristics, etc.) and communicate this information to the controller 140 and/or the carrier systems 100 . In a further embodiment, the vehicle 400 may include a dimensioning device and/or weighing device to determine characteristics of the item independently. In some embodiments, characteristics are obtained from multiple sources (e.g., stored record, captured from label, and/or independently measured).
After the characteristics are acquired, the controller 140 determines where to deposit the item in the vehicle at Block 940 . In various embodiments, the cargo area 410 within the vehicle 400 may be configured to store items of particular sizes/weights in particular locations. For example, some vehicles 400 may be configured with multiple storage locations to accommodate items of a predetermined threshold sizes (e.g., one or more dividers for each shelf, separate conveyors, and the like to separate items). For example, a vehicle may comprise storage locations configured to store small, medium, large items where each category of item size has an associated size threshold. In some embodiments, the cargo area 410 may include an area to accommodate irregular items that would not fit within the threshold sizes.
In various embodiments, the controller 140 compares the acquired characteristics against the threshold parameters for storage locations to determine which storage locations could accommodate the item at Block 940 . The controller 140 also identifies storage locations having capacity to receive the item. In various embodiments, the controller 140 monitors where items are placed (and removed from) and can therefore identify which storage locations are available. In some embodiments, the storage locations themselves have monitoring devices to indicate whether an item is present (e.g., proximity switches, light curtains, and the like). This information may be communicated back to the controller 140 .
In some embodiments, a bin or shelf may be reserved for pickups and/or unsuccessfully delivered items. In this case, the controller 140 may recognize that the item is a pickup or unsuccessfully delivered item based on a variety of data. For example, the controller 140 may make the determination based on the location of the vehicle (e.g., the vehicle is on route), input from the driver via the associated mobile computing entity and/or data associated with the unique identifier. In these cases, picked up items are automatically assigned to the one or more bins reserved for pickups and/or unsuccessfully delivered items. In some cases, the reserved bins/shelves may accommodate multiple items.
After an available storage location is identified for the item, the controller 140 sends an instruction to the automated load/unload device 460 to position the item onto the appropriate storage location. For example, the controller 140 may send a signal to the automated load/unload device 460 to move to the appropriate location (i.e. fore/aft to the appropriate location and up/down relative to the appropriate shelf) and deposit the item onto the appropriate storage location. In some embodiments, the controller 140 will also send a signal to the appropriate shelf to initiate movement of the associated power rollers/conveyors to receive the item (e.g., urge the item into the storage location) and bias the item against the associated side wall of the vehicle. In various embodiments, the controller 140 stores the location of the item in memory for later retrieval when the item is to be removed from the vehicle. After positioning the item onto the appropriate location, the robot may return to a home position, ready to position an additional item.
E. Rearranging Items within the Delivery Vehicle while on Route
In various embodiments, the items within the delivery vehicle 400 may be rearranged as some items are delivered such that the storage locations are used more efficiently. For example, the automated load/unload device 460 may reposition the items to storage locations closer to the access port to provide faster retrieval of items. In some embodiments, items may be repositioned into storage locations that better fit the actual characteristics of an item.
FIG. 11 illustrates steps that may be performed to rearrange items within the vehicle 400 according to various embodiments of the invention. The exemplary process starts at Block 1000 when the repositioning process is initiated. In various embodiments, the repositioning may occur during predetermined time periods. In some embodiments, the repositioning occurs during scheduled breaks such as lunch breaks. The initiation of a lunch break may be determined based on input from the driver into an associated mobile computing entity 105 which communicates the status to the controller 140 . In other embodiments, the controller 140 may initiate repositioning of items while the vehicle is between delivery stops. For example, the controller 140 may be programmed to initiate repositioning of items between predetermined stops based on an estimated travel time between stops provided in the dispatch plan. For example, if the estimated travel time between stops exceeds a predetermined threshold (e.g., 5 minutes, 10 minutes, etc.), the controller 140 may initiate repositioning of one or more items.
In various embodiments, the controller 140 compares the acquired characteristics for items still in the cargo area 410 against the threshold parameters for vacant storage locations at Block 1010 . At Block 1020 , the controller 140 identifies which items may be repositioned to a storage location having capacity to receive the item. In various embodiments, the controller 140 identifies items that could be placed in smaller storage locations based on the stored characteristics and the threshold sizes for storage locations. In some embodiments, the items may be moved closer to the access port 415 for faster retrieval. If a storage location has become free due to delivery of an item and an item could be more efficiently stored in that location, the controller 140 may send a repositioning instruction to the automated load/unload device 460 to retrieve and reposition the item into the new location. For example, a small item may be stored in a medium location because all of the small locations were taken when the item was initially loaded. Once a small location becomes available, the controller 140 may instruct the automated load/unload device 460 to move the small item to the vacant small location. This would vacate a medium location to receive a pickup item if necessary.
After an available storage location is identified for the item, the controller 140 sends an instruction to the automated load/unload device 460 to position the item onto the appropriate storage location at Block 1030 . For example, the controller 140 may send instructions to the automated load/unload device 460 to move to a position proximate the appropriate storage location (i.e. fore/aft to the appropriate location and up/down relative to the appropriate location) and retrieve the item from the shelf. In some embodiments, the controller 140 will also sends a signal to the appropriate storage location to initiate movement of the associated power rollers/conveyors to move the item towards and onto the automated load/unload device 460 (e.g. onto a platform of the automated load/unload device). The controller 460 may also send instructions to the automated load/unload device 460 to initiate powered rollers/conveyor as well to receive the item. The automated load/unload device 460 . In other embodiments, the automated load/unload device 460 grasps the item from the shelf without the associated shelf being activated.
After the item is obtained by the automated load/unload device 460 , the automated load/unload device may move to the new storage location (i.e. fore/aft to the appropriate location and up/down relative to the appropriate location) and deposit the item onto the new storage location. In some embodiments, the controller will also send a signal to the appropriate storage location to initiate movement of the associated power rollers/conveyors to receive the item and bias the item against the associated side wall of the vehicle. In various embodiments, the controller stores the location of the item in memory for later retrieval when the item is to be delivered. After positioning the item onto the appropriate location, the automated load/unload device 460 may return to a home position, ready to position an additional item.
