Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In the present embodiment, the same components are designated by the same reference numerals in principle, and repeated description thereof will be omitted. It should be noted that the present embodiment is merely an example for realizing the present invention and does not limit the technical scope of the present invention.

FIG. 1 is a block diagram showing a configuration example of a picking system. The picking system includes, for example, a picking work instruction presenting device 100, a picking device 200, and a loading device 300 connected to each other by a network 400 such as the Internet or an intranet. The picking work instruction presenting device 100 acquires a plurality of work instructions including a plurality of orders, determines the execution order of the work instructions included in the plurality of work orders, or determines the work order to be executed next, and causes the picking device 200 to execute the work order. It is transmitted or output to a display or the like of the picking work instruction presenting device 100.

For example, the picking device 200 performs the work indicated by the work instruction according to the order received from the picking work instruction presenting device 100 (that is, picks up the product and transports the product to the loading place). Further, the picking device 200 transmits information indicating the picking work results performed by the picking device 200 to the picking work instruction presenting device 100. The picking device 200 is, for example, a robot that moves to an area (shelf) where products included in the order are arranged to perform picking work, and a movable (to a loading area) that stores the products included in the order. (Moveable) shelves, etc.

For example, when the picking device 300 receives information about an order from the picking work instruction presenting device 100, the picking device 200 loads the products transported to the loading site for each order indicated by the order information, and the loading is completed. It is a robot that transmits information indicating the loading work results to the picking work instruction presenting device 100.

A worker may manually perform a part or all of the work performed by the picking device 200 and the loading device 300. For example, when a worker performs picking work instead of the picking device 200, the worker carries, for example, a handy terminal, the handy terminal receives information on an ordered work instruction, and the worker receives an ordered work instruction. The picking work is performed according to the information, and when the picking work is completed, the work record information is input to the handy terminal and transmitted to the picking work instruction presenting device 100.

Further, for example, when a worker performs loading work instead of the loading device 300, the worker carries, for example, a handy terminal, the handy terminal receives information about an order, and the worker relates to the order. According to the information, the goods transported to the loading place are loaded, and when the loading work is completed, the loading work results are input to the handy terminal and transmitted to the picking work instruction presenting device 100.

FIG. 2 is a block diagram showing a configuration example of the picking work instruction presenting device 100. The picking work instruction presenting device 100 includes, for example, a computer including a CPU (Control Processing Unit) 110, a memory 120, an auxiliary storage device 130, an input device 140, an output device 150, and a communication device 160.

The CPU 110 includes a processor and executes a program stored in the memory 120. The memory 120 includes a ROM (Read Only Memory) which is a non-volatile storage element and a RAM (Random Access Memory) which is a volatile storage element. The ROM stores an invariant program (for example, BIOS (Basic Input / Output System)) and the like. The RAM is a high-speed and volatile storage element such as a DRAM (Dynamic Random Access Memory), and temporarily stores a program executed by the CPU 110 and data used when the program is executed.

The auxiliary storage device 130 is a large-capacity non-volatile storage device such as a magnetic storage device (HDD (Hard Disk Drive)) or a flash memory (SSD (Solid State Drive)), and is a program and a program executed by the CPU 110. Stores the data used when running. That is, the program is read from the auxiliary storage device 130, loaded into the memory 120, and executed by the CPU 110.

The input device 140 includes a device such as a keyboard and a mouse, and receives input from an operator. The output device 150 includes, for example, a device such as a display or a printer, and outputs the execution result of the program in a format that can be visually recognized by the operator. The communication device 160 is a network interface device that controls communication with other devices according to a predetermined protocol. Further, the communication device 160 may include a serial interface such as USB.

The program executed by the CPU 110 is provided to the picking work instruction presenting device 100 via a removable medium (CD-ROM, flash memory, etc.) or a network 400, and is stored in a non-volatile auxiliary storage device 130 which is a non-temporary storage medium. Will be done. Therefore, the picking work instruction presenting device 100 may have an interface for reading data from the removable media.

The picking work instruction presenting device 100 is a computer system configured on one computer physically or on a plurality of computers logically or physically configured, and is a separate thread on the same computer. It may operate, or it may operate on a virtual computer built on a plurality of physical computer resources.

The CPU 110 includes, for example, an order management unit 111, a work instruction order determination unit 112, a work instruction priority calculation unit 113, and a work instruction issuing unit 114. The order management unit 111 stores the information indicating the picking work instruction acquired via the network 400 or the input device 140 in the work instruction information 131 described later. Further, the order management unit 111 transmits information indicating the order included in the picking work instruction to the loading device 300.

The work instruction order determination unit 112 determines the order of the picking work instructions indicated by the work instruction information 131, which will be described later, based on the priority calculated by the work instruction priority calculation unit 113. The work instruction priority calculation unit 113 calculates the priority for determining the order of picking work instructions. The work instruction issuing unit 114 includes the work instruction order determined by the work instruction order determination unit 112 in the work instruction information and transmits the work instruction order to the picking device 200.

For example, the CPU 110 functions as an order management unit 111 by operating according to the order management program loaded in the memory 120, and operates according to the work instruction order determination program loaded in the memory 120, thereby operating according to the work instruction order determination unit. Functions as 112. The relationship between the program and the functional unit is the same for the other functional units included in the CPU 110.

In addition, a part or all of the functions by the functional part included in the CPU 110 may be realized by hardware such as ASIC (Application Specific Integrated Circuit) and FPGA (Field-Programmable Gate Array).

The auxiliary storage device 130 holds, for example, work instruction information 131 and work instruction issuance information 132. The work instruction information 131 shows the details and history of the picking work instruction. The work instruction issuance information indicates a work instruction issued by the picking work instruction presenting device 100 to the picking device 200. Part or all of the information stored in the auxiliary storage device 130 may be stored in the memory 120, or may be stored in the database connected to the picking work instruction presenting device 100.

In the present embodiment, the information used by the picking system may be represented by any data structure without depending on the data structure. In this embodiment, the information is expressed in a table format, but for example, a data structure appropriately selected from a list, a database, or a queue can store the information.

FIG. 3 is an example of work instruction information 131. The work instruction information includes, for example, an instruction ID column 1311, an order ID column 1312, a product ID column 1313, a quantity column 1314, an area column 1315, a delivery date column 1316, and a pick completion date / time column 1317.

The instruction ID field 1311 holds an ID that uniquely identifies the picking work instruction. The order ID column 1312 holds an ID that uniquely identifies the order included in the work instruction. The product ID field 1313 holds an ID that uniquely identifies the product to be picked included in the order. The quantity column 1314 holds information indicating the quantity of the product to be picked.

The area column 1315 holds information indicating an area (shelf) in which products are stored. The delivery date column 1316 holds information indicating the delivery date of the order. The pick completion date / time column 1317 holds information indicating the date / time when the picking of the product is completed, which is indicated by the work record information received from the picking device 200. For products for which the picking work has not been completed, the value is not stored in the pick completion date / time column 1317.

The work instruction acquired by the picking work instruction presenting device 100 includes, for example, information indicating an order ID, a product ID, a product quantity, a product arrangement area, and a delivery date, and the order management unit 111 has an instruction ID for the work instruction. Is issued and stored in the work instruction information 131 in association with these information. The work instruction information 131 does not have to include the area column 1315.

In the example of FIG. 3, the work instruction whose instruction ID is "S1" is considered to be a total pick work instruction because only the same product (product ID is "P1") is included. Since the work instruction whose instruction ID is "S2" includes only the same order (order ID is "4"), it is considered to be an order pick work instruction. Since the work instruction whose instruction ID is "S3" includes only the same area (area is "A5"), it is considered to be a work instruction for picking a product from the same movable shelf. The same order may be included in another instruction.

Even if the picking work instruction presenting device 100 of the present embodiment receives such various types of work instructions, the order of the work indicated by these work instructions is determined so that the assortment is appropriately completed by the process described later. can do.

FIG. 4 is an example of work instruction issuance information 132. The work instruction issuance information includes, for example, an instruction ID column 1321, an instruction issuance date column 1322, and a work time column 1323. The instruction ID field 1321 holds the instruction ID. The instruction issuance date column 1322 holds information indicating the date and time when the picking work instruction presenting device 100 issues the work instruction indicated by the instruction ID to the picking device 200. The work time column 1323 holds information indicating the time required for the work of the work instruction indicated by the instruction ID (for example, represented by mh (man-hour) or the like).

FIG. 5 is a flowchart showing an example of the work instruction order determination process. The work instruction order determination process may be started, for example, every predetermined time (for example, every 5 minutes), or the input device 140. It may be started in response to a request from the user via the picking device 200 or the loading device 300.

The work instruction order determination unit 112 is included in the unfinished picking work instruction, that is, the work instruction information 131, but the instruction issuance date is not stored in the work instruction issuance information 132 (or is not included in the work instruction issuance information 132). The record of the work instruction information 131 of the instruction ID is read (S501). The work instruction order determination unit 112 determines whether or not a value is stored in the pick completion date / time column 1317 of the work instruction information 131 for each order indicated by the record read in step S501, thereby performing unfinished picking. The progress of the picking work of each order included in the work instruction is specified (S502).

The work instruction order determination unit 112 identifies the following order group when the work indicated by each work instruction indicated by the instruction ID is executed (S503).

(1) Order group where pick start & loading is completed (2) Order group where pick start & loading is not completed (3) Order group where pick is not started & loading is completed (4) Pick not started & loading is not completed Order group

Since the pick work of one order may be distributed and included in a plurality of instructions, there may be an order in which the pick work is not completed even if the work indicated by a certain work order is completed. .. Here, the order in which the pick is started and the assortment is completed means that the picking work of some products has been started before the work indicated by the work instruction is executed (that is, the pick of the order in any of the work instructions). The work has already started), and when the work indicated by the work instruction is executed, the picking work of all products is completed, which is an order. An order for which pick start & assortment is not completed means that the pick work of some products has already been started before the work indicated by the work order is executed (that is, the pick work of the order is performed in one of the work orders. It is an order that the picking work of all products is not completed (that is, the picking work of some products is not completed) even if the work indicated by the work instruction is executed.

The order for which the pick has not been started and the loading is completed means that the pick work has not been started for all products before the work indicated by the work order is executed (that is, the order for all work orders including the order). The pick work has not been started yet), and when the work indicated by the work instruction is executed, the pick work of all products is completed. An order in which picks have not been started and loading has not been completed means that the pick work has not been started for all products before the work indicated by the work order is executed (that is, the order is in all work orders including the order). The pick work of all products is not completed (that is, the pick work of some products is not completed) even if the work indicated by the work instruction is executed.

For example, it is assumed that only the work instructions of the instruction IDs "S1", "S2", and "S3" are incomplete. The instruction with the instruction ID "S1" consists of the work of the order with the order ID "1" and the order with the order ID "2", and the order with the order ID "1" in the instruction ID "S1" starts the pick work. It is assumed that the pick work of the order whose order ID is "2" has been completed and has not been started. Further, it is assumed that the instruction of the instruction ID "S2" consists of the work of the order of the order ID "1", and the pick work of the order of the order ID "2" in the instruction ID "S2" has not been started. Further, the instruction of the instruction ID "S3" consists of the work of the order of the order ID "2" and the order of "3", and the order of the order ID "S3" of the order ID "2" is the pick work. It is assumed that the work has been started and the pick work of the order whose order ID is "4" has not been started.

That is, in this situation, before the work instruction is issued, the order with the order ID "1" and the order with the order ID "2" are in the state of starting the pick, and the order with the order ID "3" has not been picked. It is in the state of starting.

At this time, for example, when the picking operation of the work instruction of the instruction ID "S1" is executed, the order of the order ID "1" is the pick start & the assortment is incomplete, and the order of the order ID "2" is the pick. The start and assortment are completed, and the order with the order ID "3" is not picked and the assortment is not completed. That is, when the picking work of the work instruction of the instruction ID "S1" is executed, the order of (1) is 1, the order of (2) is 1, the order of (3) is 0, and the order of (4) is 1. One order is generated.

Further, for example, when the picking work of the work instruction of the instruction ID "S2" is executed, the order of the order ID "1" is the pick start & the loading is completed, and the order of the order ID "2" is the pick start. & Assortment is incomplete, and the order with order ID "3" is not picked and the assortment is incomplete. That is, when the picking work of the work instruction of the instruction ID "S2" is executed, the order of (1) is 1, the order of (2) is 1, the order of (3) is 0, and the order of (4) is 1. One order is generated.

Further, for example, when the picking work of the work instruction of the instruction ID "S3" is executed, the order of the order ID "1" is the pick start & the assortment is incomplete, and the order of the order ID "2" is the pick start. & Assortment is incomplete, and picks have not been started for orders with an order ID of "3" and assortment is completed. That is, when the picking work of the work instruction of the instruction ID "S3" is executed, the order of (1) is one, the order of (2) is one, the order of (3) is one, and (4). 0 orders are generated. As described above, the work instruction order determination unit 112 specifies the order group of (1) to (4) above when the work indicated by each work instruction indicated by the instruction ID is executed.

Subsequently, the work instruction priority calculation unit 113 calculates the priority of each work instruction based on the order group specified in step S503 (S504). Specifically, for example, the work instruction priority calculation unit 113 includes each work instruction in the number of orders included in the order group of (1) above × the score of (1) + the order group of (2) above. The number of orders x the score of (2) + the number of orders included in the order group of (3) above x the score of (3) + the number of orders included in the order group of (4) above x the score of (4). Calculated as the priority when the instruction is executed.

During the picking work of an order, the picked goods are transported to the packing place, so the goods of the order occupy a part of the space of the packing place until the packing of the order is completed. .. In other words, if the number of orders for which picks have been started and the assortment has not been completed increases, the number of products staying at the assortment site will increase. Therefore, for example, in order to complete the work of as many orders as possible while reducing the number of products staying at the packing place, it is necessary to reduce the number of orders during the pick start and increase the orders for which the packing is completed. Is required. It is desirable that each score for calculating the above-mentioned priority is defined as (1) score ≥ (3) score ≥ (2) score ≥ (4) score.

Specifically, for example, the score of (1) = +2, the score of (3) = + 1, the score of (2) = 0, and the score of (4) = -1 may be predetermined. That is, it is preferable that each score is set so that the higher the order for which the assortment is completed and the smaller the order for which the pick is being started, the higher the priority. Further, for example, the score of (1) = +2, the score of (3) = +1, the score of (2) = 0, the score of (4) = 0, the score of (1) = +2, and the score of (3). Some scores may have the same value, such as = + 2, score in (2) = 0, and score in (4) = -1.

Subsequently, the work instruction issuing unit 114 determines the work instruction based on the priority calculated at least in step S504, and outputs the determined work instruction to the output device 150 and / or the picking device 200 (in all the picking devices 200). It may be present, or it may be only the picking device 200 capable of executing the work indicated by the work instruction) (S504).

Specifically, for example, the work instruction issuing unit 114 outputs instruction IDs and instruction contents of a predetermined number of work instructions (for example, work instructions having the highest priority) in descending order of priority. When outputting a plurality of work instructions, the work instruction issuing unit 114 may output the priority as well, or may output the work instructions sorted in order of priority.

Further, the work instruction issuing unit 114 calculates the remaining time from the current date and time of each order to the delivery date with reference to, for example, the delivery date column 1316 in the work instruction information 131, and a value determined according to the remaining time (the remaining time). For example, a predetermined decrease function (a value calculated from a predetermined decrease function (0 may be returned if the remaining time is equal to or longer than a predetermined value) with the remaining time as a variable) is added to the priority calculated in step S503. It may be adopted as a new priority.

Further, for example, a value indicating work efficiency between products included in the order or between areas may be defined in advance, and at this time, the work instruction issuing unit 114 includes each work instruction in the work instruction. A value indicating work efficiency is acquired from the product or area and the product or area included in the work executed immediately before, and the acquired value is updated as a new priority in addition to the priority calculated in step S503. You may. Further, the work instruction issuing unit 114 may add both a value based on the above-mentioned delivery date and a value based on the work efficiency to the priority.

FIG. 6 is an example of a display screen output by the work instruction issuing unit 114 to the output device 150 and / or the picking device 200 in step S505. The display screen 600 includes, for example, a work instruction display area 601, a next instruction display button 602, and a work instruction selection button 603.

In the example of FIG. 6, the work instruction content of the instruction ID having the highest priority is displayed in the work instruction display area 601. Specifically, the work instruction issuing unit 114 refers to the work instruction information 131 to acquire the instruction ID, order ID, product ID, quantity, area, delivery date, etc. of the work instruction having the highest priority. , Displayed in the work instruction display area 601. When the work indicated by the work instruction is executed for each order displayed in the work instruction display area 601 by the work instruction issuing unit 114, each order is placed in any of steps (1) to (4) of step S503. Further information indicating whether it is applicable may be displayed. In the example of FIG. 6, the information of one work instruction is displayed in the work instruction display area 601. However, a plurality of work instructions may be displayed (for example, in descending order of priority).

When the next instruction display button 602 is selected, the work instruction displayed in the work instruction display area 601 is changed to the work instruction having the next highest priority. When the work instruction selection button 603 is selected, the work instruction displayed in the work instruction display area 601 is issued, and the selected time of the work instruction ID is the instruction issuance date of the work instruction issuance information 132. It is stored in column 1322.

The picking work instruction presenting device 100 of this embodiment calculates the priority of each work instruction based on the pick start status and the loading completion status in the order, and outputs at least the information of the work instruction having a high priority. This allows the user to be presented with work instructions to be executed next so that the assortment for each order is prioritized. As a result, the picking work instruction presenting device 100 of the present embodiment solves the space shortage of the loading place, reduces the waiting time of the personnel or the machine performing the post-process of loading, and reduces the shipping lead time. Or can.

Hereinafter, the differences from the first embodiment will be mainly described, and the same description will be omitted as appropriate. The picking work instruction presenting device 100 of the first embodiment proposes one work instruction to be executed next, but the picking work instruction presenting device 100 of the present embodiment comprises one or more work instructions to be executed next. Propose a group of work instructions.

FIG. 7 is a block diagram showing a configuration example of the picking work instruction presenting device 100 of this embodiment. The picking work instruction presenting device 100 of the present embodiment is different from the picking work instruction presenting device 100 of the present embodiment of the first embodiment in that the auxiliary storage device 130 further includes the work resource information 133. The work resource information 133 indicates a resource capable of executing the work indicated by the work instruction.

FIG. 8 is an example of work resource information 133. The work resource information 133 includes, for example, an instruction ID column 1331, a work time column 1332, a work group column 1333, and a number of people column 1334. The instruction ID column 1331 holds the instruction ID. The work time column 1332 holds information indicating the time required for the work of the work instruction indicated by the instruction ID (for example, represented by mh (man-hour) or the like). The work group column 1333 indicates a work group capable of executing the work related to the work instruction indicated by the instruction ID.

The number of people column 1334 holds information indicating the number of people belonging to the working group. The work group may include not only workers (humans) but also work machines. In this case, the number of people column 1334 also holds information indicating the number of machines. Further, since there is a case where each of a plurality of work groups can execute the work related to the work instruction indicated by a certain instruction ID, one line is as shown in the first line and the second line of the work resource information 133 in FIG. Multiple work groups may correspond to the instruction ID. Further, when a plurality of work groups correspond to one instruction ID, the value of the work time column 1332 may be different for each work group.

In the work resource information 133 of FIG. 8, the work time and the work group are defined for each work instruction, but the work time and the work group may be defined for each picking work or each order.

FIG. 9 is a flowchart showing an example of the work instruction order determination process of this embodiment. Following step S502, the work instruction order determination unit 112 generates all the sequences (that is, the combination of work instructions and the execution order of the work instructions in the combination) consisting of unfinished picking work instructions. Further, the work instruction order determination unit 112 performs the work instruction indicated by the sequence in the order indicated by the sequence by the work group indicated by the work resource information 133 (a plurality of tasks indicated by a certain work instruction). When the work group of is feasible, the time at which picking of the order included in each work instruction is completed (that is, the loading completion time of the order) is calculated (for each of the plurality of work groups) (S903).

As described above, since the work resource information 133 defines a work group capable of executing the work indicated by each work instruction and a work time of the work by the work group, the work instruction order determination unit 112 Can be used to calculate the time at which the work indicated by each work instruction ends for any sequence of unfinished picking work instructions. If there is a resource that can execute the work indicated by the plurality of work instructions in parallel, the work instruction order determination unit 112 picks the order on the premise that the plurality of work is executed in parallel. The completion time may be calculated.

In step S903, the work instruction order determination unit 112 may generate a sequence consisting of some of the unfinished picking work instructions. That is, the work instruction order determination unit 112 determines the execution order for only a part of the unfinished picking work instructions.

Subsequently, the work instruction priority calculation unit 113 calculates the priority for each of the order sequences consisting of the above-mentioned unfinished picking work instructions (S902). Specifically, for example, the work instruction priority calculation unit 113 is the total of the number of orders in progress and the number of orders for loading completion in the XY plane with the date and time as the X-axis and the cumulative order number as the Y-axis. The date and time transition of the number of orders in the area surrounded by the graph showing the date and time transition and the graph showing the date and time transition of the number of orders for the completion of loading (that is, the pick is in progress (occupying a part of the space of the loading area)). The area of the area) is calculated as a priority for each sequence.

Subsequently, the work instruction issuing unit 114 determines the execution order of the work instructions to be selected based on at least the priority calculated in step S504, and sets the determined execution order to the output device 150 and / or the picking device 200 (all). It may be the picking device 200 of the above, or only the picking device 200 capable of executing the work indicated by the work instruction) (S903).

Specifically, for example, the work instruction issuing unit 114 has the priority output in step S902 among the execution orders in which the work end time specified in step S901 is before the value in the delivery date column 1316 of the work instruction information 131. The instruction ID and the instruction content (for example, which work group executes the work indicated by which instruction) are output in a predetermined number of execution orders (for example, the execution order with the highest priority) in descending order. Further, when outputting a plurality of work instructions, the work instruction issuing unit 114 may also output the priority, or may output the work instructions sorted in order of priority.

FIG. 10 is an example of a display screen output by the work instruction issuing unit 114 to the output device 150 and / or the picking device 200 in step S903. The display screen 1000 includes, for example, a work instruction order display area 1001, a work instruction detail display button 1002, a next execution order display button 1003, and an execution order selection button 1004.

In the example of FIG. 10, in the work instruction order display area 1001, the instruction ID of the execution order having the highest priority is displayed. Specifically, the graph used for calculating the priority is further displayed in the work instruction order display area 1001. Of the two curves, the curve with the larger Y-axis value shows the total date and time transition between the number of orders in progress and the number of orders for the completion of loading, and the curve with the smaller value on the Y-axis shows the number of orders for the completion of loading. The date and time transition is shown, and the area of the area (shaded area) surrounded by these two curves indicates the priority. By displaying such a graph in the work instruction order display area 1001, the user can visually recognize how many orders stay in the loading area.

In the example of FIG. 10, the work instruction order information in one order is displayed in the work instruction order display area 1001, but the work instruction information in a plurality of orders (for example, in descending order of priority) is displayed. May be good.

When the work instruction detail display button 1002 is selected, for example, the work instructions included in the work order displayed in the work instruction order display area 1001 are displayed in the same manner as the contents displayed in the work instruction display area 601 of FIG. Is displayed on the display screen 1000.

When the next execution order display button 1003 is selected, the order of the work instructions displayed in the work instruction order display area 1001 is changed to the order having the next highest priority. When the execution order selection button 1004 is selected, the work instructions are issued in the order displayed in the work instruction order display area 1001, and the selected time of the work instruction ID is the work instruction issuance information 132. It is stored in the instruction issue date column 1322.

The picking work instruction presenting device 100 of the present embodiment calculates the priority of a plurality of ordered work instructions based on the time-series transition of the number of orders staying at the packing station, and at least the order of high priority. By outputting the information of the work order with the attachment, it is possible to present the user with the order of the work order to be executed next so as to give priority to the assortment for each order. As a result, the picking work instruction presenting device 100 of the present embodiment solves the space shortage of the loading place, reduces the waiting time of the personnel or the machine performing the post-process of loading, and reduces the shipping lead time.
