  Embodiments for carrying out the invention will be described below with reference to the drawings.

(First embodiment)
FIG. 1 is a block diagram of a delivery object sorting system according to an embodiment. The configuration of the delivery object sorting system will be described with reference to FIG. The delivery object sorting system includes a loading unit 100 for loading a delivery target, a destination recognition unit 200, a sorting processing unit 300, a take-out unit 600, a delivery record DB (database) 400, a map DB 500, and a delivery target. And a control unit 700 that controls the entire product sorting system.

  The input unit 100, the destination recognition unit 200, the sorting processing unit 300, and the take-out unit 600 are along a conveyance path (not shown) provided with conveyance means such as a nipping conveyance belt and a belt conveyor for conveying the delivery object. Provided. In the transport path, a branch is provided for each transport destination of the delivery object in order to sort the delivery object.

  The input unit 100 is used to input a delivery object by an operator or a robot. The delivery object thrown into the throwing unit 100 is sent to the destination recognition unit 200 by the transport means.

  The destination recognizing unit 200 captures an image of the delivery object by imaging the delivery object using an imaging unit (not shown) such as a camera, and uses an optical character recognition (OCR) or the like to characterize the address character string. Is to read. The destination recognition unit 200 can obtain the destination address information of the delivery object by performing destination recognition on the address described in the delivery object that has been transported by the transport unit.

  The sorting processing unit 300 performs sorting processing by selecting a delivery destination branched from a delivery object that has been transported by the transport means based on a predetermined standard. The sorting processing unit 300 includes a sorting processing unit 310 for each delivery time zone and a sorting processing unit 320 for each delivery area.

  The delivery time zone sorting processing unit 310 sorts delivery objects according to delivery time zones obtained by dividing the business hours for delivery into a plurality of times. The delivery area sorting processing unit 320 sorts the delivery object according to the delivery area whose destination address is divided into a plurality of delivery target areas. The delivery time zone sorting processor 310 and the delivery area sorting processor 320 may process in the same zone on the transport path or in different zones, but in this embodiment, the delivery object is delivered to the delivery time. The case where the sorting process by band and the sorting process by delivery area are processed in the same section on the conveyance path is shown.

  In the present embodiment, the delivery object is transported twice on the same transport belt, and the sorting processing unit 300 performs sorting processing by delivery time zone in the first stage and sorting processing by delivery area in the second stage. For this reason, this delivery object sorting system is provided with two modes: a “sorting mode by delivery time zone” and a “sorting mode by delivery area”. These modes are switched in accordance with, for example, an input from an operator to a mode selection unit 710 provided in the control unit 700 that controls the entire system.

  The control unit 700 includes the mode selection unit 710 described above and controls the delivery target sorting process.

  The delivery time zone sorting processing unit 310 selects a delivery time zone for delivering the delivered delivery object with reference to a delivery result DB 400 described later. When the delivery time zone is selected, the transport unit is controlled by the control unit 700 so as to transport the delivery object to the transport destination corresponding to the delivery time zone. As a result, the delivery object is sorted by delivery time zone through the branched transport path.

  The delivery area classification processing unit 320 specifies a delivery area for delivering the delivered delivery object with reference to a map DB 500 described later. When the delivery area is specified, the transport unit is controlled by the control unit 700 so as to transport the delivery object to the transport destination corresponding to the delivery area. As a result, the delivery object is sorted by delivery area through the branched conveyance path.

  The take-out unit 600 is a unit for taking out the delivery object that has been carried out from the carrying path by an operator or a robot. When the delivery time zone sorting mode is applied, a delivery time zone sorting box 610 corresponding to the delivery time zone of the delivery object is arranged in the take-out unit 600. When the delivery area sorting mode is applied, a delivery area sorting box 620 corresponding to the delivery area of the delivery object is arranged in the take-out unit 600.

  The delivery time zone sorting box 610 is a portable storage device that stores one or more delivery destinations such as a roll box pallet, which are arranged at a branch destination of a conveyance path branched according to the delivery time zone. That is, the delivery time zone sorting box 610 is arranged corresponding to the delivery time zone. The delivery object is conveyed by the delivery time zone sorting processing unit 310 so as to be sorted according to the delivery time zone, then taken out from the transport path and accumulated in the delivery time zone sorting box 610.

The delivery box for each delivery area 620 is a portable storage tool that stores one or more delivery destinations such as a roll box pallet, which are arranged at a branch destination of a conveyance path branched for each delivery area. That is, the delivery area-specific sorting box 620 is arranged corresponding to the delivery area. The delivery object is transported by the delivery area sorting processing unit 320 so as to be sorted by delivery area, then taken out from the transport path, and accumulated in the delivery area sorting box 620.
The delivery time zone sorting box 610 and the delivery area sorting box 620 have a sufficient capacity for collecting delivery objects. During the sorting process, if the capacity for collecting the delivery object to be transported next in the sorting box is insufficient, a sorting box having a sufficient stacking capacity is newly prepared, and then transported to this new sorting box. The incoming deliveries begin to accumulate. Thereby, even when the remaining accumulation capacity of the sorting box is insufficient, the sorting process is performed without being interrupted.

  As long as it has a shape that can be easily moved and loaded, the shapes of the delivery time zone sorting box 610 and the delivery area sorting box 620 may be shapes other than the roll box pallet.

  The delivery time zone sorting box 610 and the delivery area sorting box 620 may be used in common regardless of which sort mode is applied. That is, the sorting box arranged in the take-out unit 600 when the delivery time zone sorting mode is applied is used as the delivery time zone sorting box 610, and the delivery area sorting mode is applied to the take-out portion 600 when the delivery area sorting mode is applied. The arranged sorting box is used as a sorting box 620 for each delivery area.

  The delivery result DB 400 stores, for each destination address, the time zone in which the recipient of the delivery destination is at home (that is, the time zone in which delivery was possible) and the number of times or the percentage of deliveries during that time zone in the past delivery. It is. The delivery result DB 400 is referred to by the delivery time zone sorting processing unit 310 and is used to select an optimal delivery time zone for the destination address.

  The delivery record DB 400 is updated by the delivery information management system 800. The delivery information management system 800 is a system that stores information on completion of delivery of a delivery object and delivery completion time. When the delivery object is delivered to the delivery destination, these pieces of information are transmitted from the terminal owned by the driver to the delivery information management system 800. That is, the delivery information management system 800 is a system that manages information (delivery log) that is the basis for constructing the delivery record DB 400.

  The delivery record DB 400 is constructed based on the delivery record information updated by the delivery information management system 800. As a result, it is possible to select a time zone in which the delivery recipient is more likely to be at home.

  The delivery information management system 800 stores information on the presence / absence of the desired reception time zone reported from the recipient of the delivery destination, or delivery time zone designation information designated by the sender when the delivery object is shipped. Or may be stored. In that case, the delivery time zone sorting processing unit 310 can select the delivery time zone by combining the delivery result information, the information reported by the recipient of the delivery destination, and the information designated by the sender at the time of shipping. .

  In other words, if there is information reported from the recipient of delivery or information specified by the sender when the delivery object is shipped, the sorting processing unit 310 according to the delivery time zone What is necessary is to preferentially select a delivery time zone based on information designated by the sender at the time of delivery of the delivery object.

  The map DB 500 stores information on delivery areas obtained by dividing a delivery target area in which the delivery target sorting system is used. As a method for dividing the delivery target area, for example, an arbitrary division method such as a range in which a driver who delivers a delivery target to a delivery destination can move by one loading is used.

  Each delivery area is assigned a serial number, and the map DB 500 stores each delivery area A1 to Am in association with address information belonging to each delivery area A1 to Am. In the map DB 500, when the destination address recognized by the destination recognition unit 200 is referred to by the delivery address sorting processing unit 320, the delivery address sorting processing unit 320 specifies the delivery area to which the destination address belongs.

  FIG. 2 is an example of information stored in the delivery record DB 400 of the delivery object sorting system according to the embodiment. The delivery result DB 400 will be described with reference to FIG. Here, information on delivery results to an arbitrary address ABC is shown as an example.

  In this example, the delivery time zone is divided into three, a delivery time zone T1 (8:00 to 12:00), a delivery time zone T2 (12:00 to 16:00), and a delivery time zone T3 (16:00 to 20:00). Yes. The number of times the address ABC recipient has been successfully delivered at home is stored for each delivery time zone. That is, it can be seen that the recipient of address ABC out of a total of six deliveries has been delivered five times at home during the delivery time period T2.

  Based on this information, in the delivery time zone sorting process described later, it is determined that the delivery time zone T2 has a high at-home probability, the delivery time zone T2 is selected, and the delivery time zone sorting corresponding to the delivery time zone T2 is performed. The delivery object is conveyed to the box 610.

  Similarly, for addresses with delivery results (address DEF, address GHI, etc.), information of delivery results by delivery time zone is stored for each address.

  In this example, the delivery time zone is divided into three, but the delivery time zone may be in other divided forms such as every hour, every day of the week, or a combination of day of the week and time.

  In addition, the delivery result information may be in other forms as long as it can estimate the at-home probability of the recipient of the delivery destination, such as a record of the delivery time zone when the recipient was absent when visiting the delivery destination. There may be.

  FIG. 3 is an example of information stored in the map DB 500 of the delivery object sorting system of the embodiment. The map DB 500 will be described with reference to FIG. Here, information about an arbitrary delivery target area is shown as an example.

  In this example, the delivery target area is the delivery area A1 (Minato-ku Shibaura 1-chome to 4-chome), delivery area A2 (Minato-ku Shiba Park and Minato-ku Shiba Daimon), delivery area A3 (Minato-ku Mita), Delivery area A4 (Minato-ku Shiba 1-chome to 5-chome). For example, when the delivery address of the delivery object is “1 of Shibaura 1-chome 1, Minato-ku”, the delivery area classification processing unit 320 specifies that the delivery object belongs to the delivery area A1.

  Based on the information on the specified delivery area, in a delivery area sorting process to be described later, the delivery area sorting processor 320 identifies the delivery area A1 as the delivery area to which the destination address belongs, and the delivery area corresponding to this delivery area A1 The delivery object is conveyed to the separate sorting box 620.

  FIG. 4 is a flowchart illustrating an overall flow of the delivery object sorting system according to the embodiment. With reference to FIG. 4, the flow from when a delivery object is input to the delivery object sorting system to when it is loaded onto a delivery truck will be described.

  First, the mode selection unit 710 included in the control unit 700 sets the mode of the delivery object sorting system to the delivery time zone sorting mode.

  A serial number is assigned to a delivery object processed by the delivery object sorting system of the embodiment. This is represented by a variable i set from 1. The delivery object is sequentially placed from the input unit 100 onto the conveyance path by an operator or a robot. First, the first delivery object is set as a processing object (step S101).

  The destination recognition unit 200 reads the destination address of the first delivery object and performs destination recognition (step S102).

  The first delivery object whose destination address is recognized by the destination recognition unit 200 is subjected to a delivery time zone sorting process by the delivery time zone sorting unit (step S103). As a result, the delivery object 1 is sorted into the delivery time zone sorting box 610 corresponding to any one of the delivery time zones T1 to Tn. That is, the sorted delivery objects are accumulated in any one of the delivery time zone sorting boxes BT1 to BTn arranged corresponding to the delivery time zones.

  Here, it is determined whether or not the sorting process for each delivery time zone has been completed for all delivery objects (step S104). While the delivery time zone sorting process has not been completed for all delivery objects (No in step S104), the process proceeds to the variable i + 1th delivery object (step S105).

  On the other hand, when the sorting process by delivery time zone is completed for all delivery objects (Yes in step S104), the delivery objects collected in the delivery time zone sorting box BT1 corresponding to the delivery time zone T1 having the earliest delivery time zone. Are delivered to the vicinity of the inlet of the delivery object sorting system by the operator or robot while being collected in the delivery time zone sorting box BT1 (step S106).

  Here, the mode selection unit 710 included in the control unit 700 changes the mode of the delivery object sorting system to the delivery area sorting mode. With these two sorting modes, it is possible to perform both delivery time zone sorting processing and delivery area sorting processing using the same transport path.

  At this time, the delivery unit sorting boxes BT1_A1 to BT1_Am are arranged in the take-out unit 600.

  Here, a serial number is again assigned to the delivery objects collected in each delivery time zone sorting box. This is represented by a variable k set from 1. For example, the kth delivery object in the delivery time zone sorting box BTj is represented as a delivery object Tj_k. j is 1 ≦ j ≦ n. Delivery objects carried to the vicinity of the insertion port are sequentially placed on the conveyance path from the input unit 100 by an operator or a robot.

  First, the delivery object T1_1, that is, the first delivery object in the delivery time zone sorting box BT1 is set as the processing target of the delivery area sorting process (step S107).

  The destination recognition unit 200 reads the destination address of the delivery object T1_1 and performs destination recognition (step S108).

  The delivery object T1_1 whose destination address is recognized by the destination recognition unit 200 is subjected to delivery area sorting processing by the delivery area sorting unit (step S109). As a result, the delivery object T1_1 is sorted into the delivery area sorting box 620 corresponding to any one of the delivery areas A1 to Am. That is, the sorted delivery objects are collected in any one of the delivery area sorting boxes BT1_A1 to BT1_Am arranged corresponding to the delivery areas.

  Here, in the delivery areas A1 to Am, for example, serial numbers are assigned in order along a delivery route that allows the driver to efficiently deliver the delivery object.

  Here, it is determined whether or not the sorting process by delivery area has been completed for all delivery objects accumulated in the sorting box by delivery time zone BT1 (step S110). While the delivery area sorting process has not been completed for all delivery objects collected in the delivery time zone sorting box BT1 (No in step S110), the variable k + 1-th variable in the delivery time zone sorting box BT1 exists. It progresses to the process about a delivery target object (step S111).

  On the other hand, when the delivery area sorting process is completed for all delivery objects collected in the delivery time zone sorting box BT1 (Yes in step S110), all delivery area sorting boxes in which the delivery objects are gathered are For example, the delivery area sorting boxes BT1_A1 to the delivery area sorting boxes BT1_Am are stacked on a delivery truck so that the delivery objects can be efficiently taken out and delivered (step S112).

  Subsequently, it is determined whether or not the delivery area sorting process has been completed for all the delivery time zone sorting boxes BT1 to BTn sorted in the delivery time zone sorting process (step S113). While the sorting process by delivery area is not finished for all the sorting boxes by delivery time zone BT1 to BTn sorted by the sorting process by delivery time zone (No in step S113), the variable j + 1 is sorted by the delivery time zone. It progresses to the process about a box (step S114).

On the other hand, when the delivery area sorting process is completed for the delivery objects in all the delivery time zone sorting boxes BT1 to BTn sorted in the delivery time zone sorting process (Yes in step S113), the delivery object sorting system includes: The process ends.
By performing the sorting process in two stages as described above, the delivery object can be loaded on the delivery truck for each delivery time zone and each delivery area, so that the efficiency of delivery work is improved.

  Next, the details of each of the delivery time zone sorting process in step S103 and the delivery area sorting process in step S109 in FIG. 4 will be described with reference to FIGS.

  FIG. 5 is a flowchart illustrating a flow of the sorting process by delivery time zone according to the embodiment. With reference to FIG. 5, the flow of sorting processing by delivery time zone for an arbitrary delivery object i will be described.

  First, the delivery time zone sorting processing unit 310 refers to the delivery result DB 400 for the delivery object i, and obtains delivery result information to the destination address recognized by the destination recognition unit 200 (step S301). Based on the delivery result to the destination address, the optimum delivery time zone for delivering the delivery object is selected (step S302). The delivery time zone to be selected is a time zone in which the delivery destination recipient has the highest probability of being at home.

If the delivery information management system 800 has information reported from the delivery recipient or information specified by the sender at the time of shipping, the delivery processing unit 310 according to the delivery time zone reports the information from the delivery recipient. A delivery time zone based on information or information specified by the sender at the time of shipping may be selected with priority.
The delivery object i is sorted into a delivery time zone sorting box 610 corresponding to the selected delivery time zone (steps S3031 to S303n).

  It should be noted that the optimal delivery time from the delivery record DB 400 for the reason that there is no delivery record to the destination address or the delivery record is always absent at the time when the sorting process by delivery time zone is executed. If the band cannot be selected, the delivery object i is sorted into the delivery time zone sorting box BT1 corresponding to the earliest delivery time zone (step S304). Thereby, a delivery object can be delivered as soon as possible. If the recipient is absent, request a re-delivery by posting an absence report indicating that the recipient has been delivered but not delivered due to absence, and waiting for the recipient to contact you. This is because it increases the possibility of being able to receive the drug earlier.

  If the optimum delivery time zone cannot be selected from the delivery record DB 400, it is eliminated once, and after the delivery time zone sorting process for all delivery objects is completed, the smallest delivery time zone sorting box is the smallest. You may make it sort to 610. FIG. In this case, the available capacity of the delivery time zone sorting box 610 can be effectively utilized. In this case, delivery can be performed while avoiding busy hours.

  As described above, the delivery object i is sorted into any one of the delivery time zone sorting boxes BT1 to BTn, and the delivery time zone sorting process is completed.

  FIG. 6 is a flowchart illustrating a flow of delivery area-specific sorting processing according to the embodiment. As shown in FIG. 6, after the delivery object i is sorted into the delivery time zone sorting box BTj by the delivery time zone sorting process described above, the kth delivery target Tj_k in the delivery time zone sorting box BTj is used. The flow when the sorting process by delivery area is executed will be described.

  First, the delivery area classification processing unit 320 refers to the map DB 500 for the delivery object Tj_k, and obtains information about which delivery area the destination address recognized by the destination recognition unit 200 belongs to (step S901). Based on the information indicating which delivery area the delivery area belongs to, the delivery area to which the delivery object is delivered is specified (step S902).

  The delivery object Tj_k is sorted into a delivery area sorting box 620 corresponding to the selected delivery area (steps S9031 to S903m).

  Thus, the delivery object Tj_k is sorted into one of the delivery area sorting boxes BTj_A1 to BTj_Am, and the delivery area sorting process is completed.

(Second Embodiment)
In the first embodiment, the sorting process is divided into a sorting process by delivery time zone and a sorting process by delivery area, and the same transport path is used for each process. That is, in the first embodiment, the delivery object is thrown into the same transport path twice from the slot.

  In the second embodiment, the sorting process by delivery time zone and the sorting process by delivery area are executed along different conveyance paths. That is, a delivery time zone sorting process is executed on the first conveyance path, which is the first half of the conveyance path, and a delivery area sorting process is executed on the second conveyance path, which is the second half of the conveyance path.

  FIG. 7 is an example of a state where an arbitrary delivery object i is sorted in the delivery object sorting system of the second embodiment. FIG. 7 illustrates a case in which the sorting process is executed by connecting in series the transport path on which the delivery time zone sorting process is performed and the transport path on which the delivery area sorting process is performed. In addition, the black arrow in a figure becomes a path | route which the delivery target object i follows.

  In the delivery object sorting system, a destination address of an arbitrary delivery object i is first recognized by the destination recognition unit 200. When the destination address is recognized by the destination recognition unit 200, the delivery time zone sorting processing unit 310 refers to the delivery result DB 400. According to the information of the delivery result to the destination address of the delivery object i, it is determined that, for example, the home time probability of the delivery time zone T2 is the highest among the delivery time zones T1 to Tn. For this reason, the delivery object i is sent to the transport path that branches to the delivery time zone sorting box BT2.

  Subsequently, the delivery object i is taken out from the delivery time zone sorting box BT2, and the destination recognition unit 200 recognizes the destination address again. When the destination address is recognized by the destination recognition unit 200, the delivery area sorting processing unit 320 refers to the map DB 500. The destination address of the delivery object i is specified to belong to, for example, the delivery area A1 among the delivery areas A1 to Am. For this reason, the delivery object i is sent to the conveyance path that branches to the delivery area-specific sorting box BT2_1.

  When the sorting process by delivery time zone and the sorting process by delivery area are completed for all delivery objects by delivery area sorting boxes BT2_A1 to BT2_Am, the delivery area including the delivery area sorting box BT2_1 in which the delivery objects i are accumulated is also included. Separate sorting boxes BT2_A1 to BT2_Am are stacked on the truck, and delivery is started.

  In the embodiment of the present invention, a delivery object is automatically sorted by delivery time zone and delivery area at a collection / delivery office before delivery, so that the delivery destination recipient of the delivery object has a high probability of being at home. Efficient delivery can be done during the time. Therefore, delivery of more delivery objects can be completed at the first visit.

  This will reduce the number of redelivery of deliverables, store costs for redelivery costs such as gasoline and labor costs, and deliveries brought home due to the absence of the recipient of delivery. It is possible to reduce the storage space for the delivery object at the collection place.

  Although several embodiments of the present invention have been described, these embodiments are presented by way of example and are not intended to limit the scope of the invention. These embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the spirit of the invention. These embodiments and their modifications are included in the scope and gist of the invention, and are also included in the invention described in the claims and the equivalents thereof.
