Description

  The present invention relates to a picking system, a picking cart, and a program capable of efficiently performing an operation of aggregating picked articles for each transaction without mistakes.

  Picking systems have been introduced at distribution centers that handle daily necessities, cosmetics, stationery, and food. In this type of picking system, products ordered from retailers are removed from storage shelves, flow racks, etc., and placed in containers (Oricon, returnable boxes, cardboard boxes, etc.) placed in picking carts, and the input is completed The containers are transported to the shipping location, then sorted to a delivery destination, loaded onto a truck or the like and shipped. In the order from the retailer, a sorting unit (one order, one transaction) such as a delivery date, a store to deliver, and a sales floor to deliver is specified. Major wholesalers and 3PL logistics companies use a higher-level system to calculate one order as multiple work orders by so-called volume calculation that determines the amount of input per container based on product dimensions, unit weight, and total weight per box. Products that are divided into container units, products that do not fit in containers (long items, heavy items), and items that are shipped in units of boxes (case shipments) are handled as separate work instructions and can be flexibly adapted to the products. ing.

  Among distribution centers that operate such picking systems, there is a sorter that aggregates transport equipment such as conveyors that transport containers for which picking operations have been completed, and containers for one work instruction unit into sorting units such as stores. In some cases, a sorting facility including a display system is also provided. If such a sorting facility is added to the picking system, shipping mistakes are less likely to occur and the sorting operation proceeds smoothly.

  However, if such a sorting facility is not installed, an operator who performs sorting selects a store name / number or course name such as a slip or a delivery label (PD label, SCM label) attached to a collected container.・ Consolidation work while visually confirming numbers. In this case, the inspection work is done by finally scanning the barcode on the delivery label and confirming the number of containers. In many cases, this sorting work has become a bottleneck, and there has been a problem that a sufficient effect cannot be obtained with respect to capital investment in the previous process (picking system).

  The present invention has been made in view of the above points, and an object of the present invention is to provide a picking system, a picking cart, and a program that can efficiently and error-freely collect picked articles at a temporary storage place or a shipping standby place. Is to provide.

In the picking system including a picking cart having a plurality of mounting tables, the present invention includes a specifying unit that collectively specifies containers required for each transaction as containers to be mounted on the plurality of mounting tables. It is characterized by that.
Containers required for each transaction can be picked at once by a multi-picking cart with multiple mounting tables, so even if there is no sorting equipment installed, one picked item can be traded. Each can be easily collected and collected in a temporary storage place, a shipping standby place, etc., and post-processing such as shipping work can be performed smoothly and without mistakes. In addition, the burden on the operator can be reduced. Note that this designation means may be configured to be able to be switched with other designation means for designating a container based on other criteria.

Further, the present invention provides a method in which the designation means, when the unprocessed container quantity among the containers required for the one transaction is the same as or more than the quantity of mountable platforms, The unprocessed container is designated for all the mounting tables that can be described.
As a result, unprocessed containers necessary for one transaction can be efficiently transported together on one multi-picking cart.

Further, the present invention is the case where the designation means is such that the number of unprocessed containers in the container required for the one transaction is less than the number of mountable mounting tables, and In the case where the unprocessed container quantity of containers required for other transactions is equal to or less than the remaining number of mountable table, the one transaction and the above-described mountable table All the unprocessed containers related to other transactions are specified.
According to the present invention, when a multi-picking cart on which a container for one transaction is placed has a vacant table, it can be used for other transactions that can place all containers required only by the vacant table. , This mounting table can be used preferentially. As a result, it is possible to collect a plurality of merchandise (containers) and efficiently collect them in a temporary storage place or a shipping standby place.

  Moreover, this invention mounts one unprocessed container of the said one transaction on the 1st mounting base of the said several mounting bases, and links | relates the mounting base and mounting bases mentioned above It is characterized by comprising work starting means for starting picking work on the condition of

In addition, the present invention is characterized by comprising output means for outputting the total number of containers required for the one transaction when the picking work is started.
By grasping the total number of containers when starting work, the necessary number of containers can be prepared in advance.

  In the picking cart having a plurality of mounting tables for mounting picked articles, the present invention collectively designates containers required for each transaction as containers to be simultaneously mounted on the plurality of mounting tables. It is characterized by having a designation means.

  Further, the present invention provides a picking system including a picking cart having a plurality of placement tables, and a designation means for collectively specifying containers required for each transaction as containers placed simultaneously on the plurality of placement tables. It is in the program characterized by making it function as.

FIG. 1 is a system configuration diagram of a picking system 1 configured using a picking cart 30 according to an embodiment of the present invention. As shown in FIG. 1, the picking system 1 places a picking management device 10 that manages the picking operation of an article (hereinafter referred to as “product”) and a mounting body (hereinafter referred to as “container”) that stores the product. And a plurality of picking carts 30 that move. A picking management apparatus (hereinafter simply referred to as “management apparatus”) 10 is connected to a host computer 20 at the higher level. Then, for example, the management device 10 receives product order data from the host computer 20. The management apparatus 10 communicates with each picking cart (hereinafter referred to as “cart”) 30,... Via the wireless router 25. For example, the management device 10 transmits information specifying a product instructed to be taken out from a predetermined position and information such as the number of the products taken out to the cart 30.

  FIG. 2 is a perspective view showing the appearance of the cart 30. As shown in the figure, the cart 30 includes a frame member 31 having a shelf shape of two upper and lower stages, and two mounting tables (also serving as a measuring instrument) 33-1 installed on the upper stage side of the frame member 31. , 2, two mounting tables (also serving as a measuring instrument) 33-3 and 4 installed on the lower side of the frame member 31, and a pair of handles 37 installed on the near side of the upper side of the frame member 31 The display unit 39 and the first scanner unit 41 installed between the pair of handles 37, the second scanner unit 43 installed on the nearer side than the handle 37, and the second scanner unit 43. The holding unit 45, a printing unit 47 installed on one upper side of the frame member 31, and a battery 49 installed on the lower side of the frame member 31 are configured.

  The frame member 31 has an upper step portion 311 and a lower step portion 313, a table portion 315 is provided on the front side of the upper step portion 311, and a caster (not shown) for moving the cart 30 is provided on the bottom surface of the lower step portion 313. Is provided.

  The upper stage mounting bases 33-1 and 3-2 each have the same substantially rectangular article mounting part 331 and are provided side by side. The lower stage mounting bases 33-3 and 4 also have the same substantially rectangular article mounting part 331 and are provided side by side.

  A pair of handles 37 are installed on the left and right to push the cart 30 in the direction of arrow A. The display unit 39 is configured with a touch panel made of liquid crystal or the like. The display unit 39 is a display unit that displays picking work instruction information instructed about the picking work while the worker pushes the cart 30, and touches this to display a result of a predetermined work or an operator side. It is also an input unit for inputting various commands. The first scanner unit 41 and the second scanner unit 43 are for reading a barcode or the like of a product to be picked. The first scanner unit 41 is fixed to the frame member 31 on the side of the display unit 39, and the second scanner unit 43 is a portable terminal and is held by a holding unit 45 provided on the frame member 31. The second scanner unit 43 performs transmission / reception with the cart 30 wirelessly.

  The printing unit 47 is installed on the side of the frame member 31 and issues a shipping label or the like to be attached to a container that accommodates the picked goods. However, the printing unit 47 has many uses. For example, when the quantity of one of the products displayed on the picking storage shelf (hereinafter referred to as “storage shelf”) or the flow rack in the picking warehouse is reduced or lost, The replenishment label is issued from the printing unit 47 and delivered to the person in charge of product replenishment, pasted on the replenishment request box or the on-site whiteboard, etc. In order to notify the user, it is possible to prevent duplication of replenishment instructions by attaching the second sheet to the corresponding location. Furthermore, a holding operation is performed to temporarily hold the picking work of the product being replenished, and a hold label is issued and pasted from the printing unit 47 to the product waiting to be replenished, and temporarily placed at a waiting place for the replenishment waiting container. Put. When a product for replenishment instruction is prepared, the storage shelf is replenished and a replenishment release operation is performed. Then, when the refill instruction is canceled, the work instruction data including the instruction of the corresponding product is distributed again. By reading the identification information (work instruction number) etc. of the hold label affixed to the container in the temporary storage area that has been put on hold, the empty cart 30 is used to check the quantity inspection and input container. Complete. Further, when a product is actually missing due to damage or a delay in arrival of goods, a missing item process is executed, a missing label is issued from the printing unit 47, and the missing item information is transmitted to the management apparatus 10. At that time, it is also used for the issuance of corrected delivery labels and statement labels, for example, when a product that has been put in a container in advance is designated. Thus, the printing unit 47 is used for various purposes.

  FIG. 3 is a block diagram of the cart 30. As shown in the figure, the cart 30 includes a CPU 57, a RAM 59, a ROM 61, a communication unit 63, the display unit 39, the upper stage mounting bases 33-1 and 3-1, and the lower stage mounting base. 33-3, 4, the first and second scanner units 41, 43, the printing unit 47, and the speaker unit 65 are connected by a bus 67.

  The CPU 57 executes various determinations and calculations to realize various functions related to the cart 30. The RAM 59 stores data read by the CPU 57, work instruction information, product files, and the like. The ROM 61 stores various types of information such as various programs executed by the CPU 57 (this program includes a picking program for causing the CPU 57 to execute the processing described below), and the CPU 57 stores the information in the ROM 61. The operation of the cart 30 is controlled by executing the control program. The communication unit 63 transmits and receives with the management apparatus 10 via the wireless router 25. The speaker unit 65 is a notification unit that performs error notification or the like by sound or voice.

  FIG. 4 is a block diagram of the management apparatus 10. As shown in the figure, the management apparatus 10 includes a CPU 11, a RAM 13, a ROM 15, an HDD (hard disk, storage means) 17, a communication unit 19, a display unit 21, and an operation unit 23 via a bus 24. Connected and configured. The CPU 11 controls the operation of the management apparatus 10 by executing a control program stored in the ROM 15. The ROM 15 stores various information such as various programs executed by the CPU 11 (this program includes a program for creating picking instruction data for causing the CPU 11 to execute the processing of FIG. 9 described below). The RAM 13 temporarily stores various information. The communication unit 19 transmits / receives data to / from each cart 30 via the wireless router 25 and transmits / receives data to / from the host computer 20.

  The management apparatus 10 performs inventory management of products, creation of picking instruction data, management of the operation state of each cart 30, and the like. The management apparatus 10 stores a product file as shown in FIG. In the example shown in FIG. 5, the product file has information such as the product name, unit mass value, and location number for each JAN code (product identification information). The product identification information may be various product identification information other than the JAN code. The location number indicates the storage location of the product in the picking warehouse. The management apparatus 10 receives order data from the host computer 20. The received order is transferred to the database (HDD 17) of the management apparatus 10, and the picking instruction data creation application or the like is used for the delivery date, department, category, packing style, and the shipment item in units of balls and roses. Volume calculation is executed to create picking instruction data for so-called packing units (container units). On the other hand, the cart 30 receives data (picking instruction data) from the management apparatus 10 by transmitting a work start request signal to the management apparatus 10 that is a host system through wireless communication, and performs work according to the instruction. .

  The picking system 1 is installed in, for example, a distribution center that handles daily necessities, cosmetics, stationery, miscellaneous goods, foods, and the like. Based on the order data received from the retail business (mass retailer supermarket, convenience store, etc.), the management device 10 sorts information on delivery / delivery flights / stores / sales, etc., product information, and quantity of sorting units (in the case of total number or The picking instruction data in the distribution center is created from the data such as the packing unit “case / ball / rose”). The created picking instruction data can be captured by the cart 30. The picking instruction data is transmitted from the management apparatus 10 to the cart 30 by receiving a work start request signal from the cart 30 as described above.

[Pattern 1] When capacity / volume calculation is executed in the host system (such as the management device 10) and 1 container = 1 work instruction As described above, in the case of a distribution center performing capacity / volume calculation, Since the capacity and volume are calculated based on the order data, of course, the number of containers (number of units) is determined in advance before starting work (of course, there is a manual container addition function if it does not go as calculated) . Here, 1 container = 1 work instruction. Here, one order means a single order received or an order unit. The delivery location and delivery time for products delivered in one order are usually the same. Therefore, not only 1 order = 1 work instruction but 1 order = multiple work instructions may be obtained. The order is not limited to one store. For example, when an order is placed for each sales floor (department) in one store, the sales floor unit is one order. That is, a unit such as an order number (or order number) assigned to each is one order.

  First, in the case of a site where capacity / volume calculation is being executed by a host system (such as the management device 10), when one order is divided into multiple work instructions, a full container is placed in a temporary storage area or a waiting area for shipment. Means for reducing the number of times of movement and the burden of store sorting (aggregation by store) will be described using the picking cart 30 having four mounting tables 33-1 to 4 shown in FIG. 2 as an example.

  The order data is received by the management apparatus (distribution server, material handling server) 10 from a wholesaler or the like via the order system. At this time, data (for example, a location number and an expiration date at the time of the previous shipment) necessary for product delivery is added from the order data, and the data layout is replaced with picking instruction data (for logistics).

  FIG. 6 shows an example of the result of calculating the quantity of containers required for each order A, B, C, D when performing capacity / volume calculation to create picking instruction data. FIG. As shown in the figure, in this example, for order A, products (1) to (8), for order B, products (1), (3), (5), (6), (8), order Picking instructions are given for products (2), (4), (7) for C, and for products (1), (2), (5), (7), (8) for order D. The description of the quantity of each product is omitted. By calculating the capacity and volume, for order A, products (1) to (4) are in container A1, products (5) and (6) are in container A2, and products (7) and (8) Is stored in the container A3. For the order B, the products (1), (3), and (5) are stored in the container B1, and the products (6) and (8) are stored in the container B2. For order C, the products (2), (4), (7) are calculated to be stored in the container C1, and for order D, the products (1), (2), (5) Is stored in the container D1, and the products (7) and (8) are stored in the container D2. The containers A1 to D2 are all containers having the same shape, and each container itself is not numbered. In the case of this specific example, the order received is the order order, specifically, the order A → B → C → D.

  Next, the management apparatus 10 determines picking instruction data in accordance with a work start request signal from the cart 30 and distributes the picking instruction data to the cart 30. At that time, the worker of the cart 30 does not need to make a determination, and receives picking instruction data defined by a predetermined standard such as duplication of work flow lines or duplication of locations.

  FIG. 9 is a flowchart showing an example of a method for determining a combination of containers that become a part of picking instruction data. The CPU 11 or the like that executes this flow constitutes a means for specifying a container to be placed on the cart 30. First, as described above, the order of the order is determined in advance. Then, the number of containers for order in the first order (the number of unprocessed containers among them) is searched, and the number of containers is compared with the total number (four) of the mounting tables 33-1 to 4 (step ST1). -1).

  If the number of containers is four or more, it is specified that the first order container is placed on all the placement bases, and the process ends (step ST1-2).

  On the other hand, if the number of containers is less than 4, it is specified that all containers for the first order are placed on each placement table (step ST1-3).

  Next, it is determined whether or not there is an order of the total number of containers (the total number of unprocessed containers) equal to the number of remaining undesignated mounting tables (step ST1-4). All the containers for the order are designated on the table, and the process is terminated (step ST1-5).

  On the other hand, if not, the process proceeds to step ST1-6, and it is determined whether there is an order of a total number of containers (total number of unprocessed containers) smaller than the number of remaining undesignated mounting tables. All containers for ordering are designated as the remaining mounting tables (step ST1-7), and the process returns to step ST1-4.

  On the other hand, if there is no more, the process moves to step ST1-8, and a part of the next order container for the next order (unprocessed container) is designated for all the remaining undesignated mounting tables. Or, in some cases, an unspecified mounting table is left empty.

  The method for determining the combination of containers will be described with reference to the specific example shown in FIG. In the case of the specific example shown in FIG. 6, the number of containers for order A in the first order is three (A1, A2, A3), and the total number of mounting tables 33-1 to 3-4 is four. The process proceeds to step ST1-3, and all (three) containers A1, A2, A3 are designated to the mounting tables 33-1, 2, 3 respectively. Next, in step ST1-4, it is determined whether or not there is an order of the same total number of containers (1) as the remaining mounting tables 33-4 (1), and this corresponds to the order C. In step ST1-5, the container C1 is designated to the mounting table 33-4.

  FIG. 7 is a diagram illustrating an installation state of the containers A1 to A3 and C1 determined as described above and mounted on the mounting tables 33-1 to 3-4. Each of the containers A1 to A3 and C1 may be placed before the picking operation is started, or a new container is placed each time one container is placed and the introduction of goods into the container is completed. You may make it mount. Hereinafter, the latter method, that is, a case where containers are placed in order will be described.

  First, one unprocessed container A1 of the one transaction is placed on a placing table (first placing table) 33-1, and a shipping label printed by the printing unit 47 is attached to the container A1. The container A1 and the mounting table 33-1 are linked by reading the barcode of the shipping label and the barcode of the mounting table 33-1 with the first or second scanner unit 41 or 43, and As a condition, picking work is started. In addition, one unprocessed container A1 of the one transaction is placed on the first placement table 33-1 of the plurality of placement tables 33-1 to 3-4, and the container A1 and the placement container described above are loaded. The means for starting the picking work on condition that the table 33-1 is linked is referred to as work starting means.

  When the picking operation is started, the fact that the total number of total containers A1, A2 and A3 required for the one transaction is three is displayed on the display unit (output means) 39 or printed. If printing is performed by the unit (output means) 47, it is preferable that the required number of containers can be prepared in advance by grasping the total number of containers when starting the work. .

  Then, picking work is started. At this time, an operation screen G1 shown in FIG. Here, FIGS. 10 and 11 show operation screens G1 to G7 displayed on the display unit 39 of the cart 30 when products are picked up in the containers A1 to A3 and C1 determined as shown in FIG. It is a figure which shows an example of transition of. On the operation screen G1 (G2 to G7), the location of the product to be picked, the number of instructions to be picked up, the name of the product, the mounting table (A is 33-1, B is 33-2, C is 33-3, D corresponds to 33-4), how many roses and balls are picked up, the location of the next product and the number of instructions, various operation buttons b, etc. It is displayed.

  That is, first, on the operation screen G1, the location (storage location) of the first product (1), product information (product name, etc.), picking quantity (case / ball / rose or total number of roses, in this example, the case is Since it is not displayed, explanation of the case is omitted below), and the worker moves to the designated location according to this guidance. Next, the product (1) is verified by scanning the product barcode attached to the product (1) at the location, or the location barcode or product barcode attached to the storage shelf. If the product verification is successful, the product (1) is put into the container A1 by the specified quantity. In the case of this cart 30, since the mounting table 33-1 is a measuring instrument, quantity inspection can be performed based on the unit weight (ball, rose) of the product, and an insertion error can be prevented. For a product (for example, a simple body warmer) having a variation in the unit weight of the product such that the measuring instrument cannot be used, the quantity may be inspected by a scan inspection that scans the entire product. When the measuring instrument is not installed, the same method for scanning all products may be selected, or a representative scan for entering the quantity or a completion button may be simply pressed.

  In this way, when the pickup of the product (1) is completed, the location of the product (2), product information (product name, etc.) and picking are displayed on the operation screen G1 of FIG. Since the quantity is guided, the worker moves to the designated location according to this guidance, and puts the product (2) at the location into the container A1 in the same manner as in the case of the product (1). When the product (2) is picked up, the products (3) and (4) are not shown in the figure, but the operator designates according to the changed operation screen G1 in FIG. 10 (a). The product (3), (4) at the location is moved to the container A1 in the same manner as in the case of the product (1). In this way, when the picking operation to the container A1 is completed, the box exchange button b1 in the operation screen G1 is touched (pressed), and the operation screen G2 is switched to, for example, FIG.

  Then, according to the instruction on the operation screen G2, the worker places a new container A2 on the placement table 33-2 and touches the confirmation button b2 in the operation screen G2, thereby operating the operation screen G3 shown in FIG. Switch to. In the same manner as described above, after performing the linking operation between the positions of the container A2 and the mounting table 33-2, the picking work of the products (5) and (6) is performed on the container A2. When the picking work of the products (5) and (6) to the container A2 is performed in the same manner as the picking work of the products (1) to (4) to the container A1, touching the box exchange button b3, for example, The operation screen G4 as shown in FIG.

  The operator places a new container A3 on the placement table 33-3 in accordance with the instruction on the operation screen G4, and touches the confirmation button b4 in the operation screen G4, so that the operation screen G5 shown in FIG. Switch. In the same manner as described above, after performing the linking operation between the positions of the container A3 and the mounting table 33-3, the picking work of the products (7) and (8) is performed on the container A3. After the picking work of the products (7) and (8) to the container A3 is performed in the same manner as described above, when the box exchange button b5 is touched, for example, an operation screen G6 as shown in FIG. .

  The operator places a new container C1 on the placing table 33-4 in accordance with an instruction on the operation screen G6, and touches the confirmation button b6 in the operation screen G6, whereby the operation screen G7 shown in FIG. 11C is displayed. Switch. In the same manner as described above, after performing the linking operation between the position of the container C1 and the mounting table 33-4, the picking work of the products (2), (4), (7) to the container C1 is performed.

  When all the picking operations are completed as described above, the cart 30 is moved to a temporary storage place, a transport facility, a shipping standby place, or the like, or if there is a separate person in charge of collection, the cart 30 is handed over to it. Next, the next picking instruction data is received and the same operation as described above is repeated.

  As described above, the picking system 1 includes a picking cart 30 having a plurality of mounting bases 33-1 to 3-4, picking that designates the type and quantity of products to be picked, and containers to be mounted on the mounting bases 33-1 to 3-4. And a management device 10 that transmits instruction data to the picking cart 30, and the picking system 1 obtains the number of containers required for each transaction, and the plurality of mounting tables 33-1 to 3-4. As a container to be placed on, a designation unit (such as the CPU 11 that executes steps ST1-1 to ST1-8) for collectively designating the containers required for each transaction is configured.

  As described above, according to the picking system 1, containers necessary for each transaction can be picked at once by the multi-picking cart 30 having a plurality of mounting tables 33-1 to 4-4. Even if it is not installed, picked products can be easily collected and collected in a temporary storage area or a shipping standby place for each transaction, and subsequent processes such as shipping work can be performed smoothly and without error. It becomes possible and the burden on the operator can be reduced. The present invention is particularly effective in a distribution center where a multi-picking cart has many mouths.

  Moreover, the said designation | designated means is less than the quantity of the unprocessed container quantity (A1-A3) of the containers required for said one transaction with respect to the quantity of the mounting bases 33-1-4 which can be mounted. In the case where the unprocessed container quantity (C1) among the containers required for other transactions is equal to or less than the remaining number of mounting tables 33-1 to 3-4 that can be placed as described above, The plurality of transactions are instructed to be picked at the same time. That is, when the cart 30 on which the containers A1 to A3 for one transaction are placed has a placement table 33-4 empty, all the containers C1 required only by the placement table 33-4 having the space are placed. This mounting table 33-4 can be used preferentially for other transactions that can be made. As a result, it is possible to collect a plurality of merchandise (containers) and efficiently collect them in a temporary storage place or a shipping standby place. That is, since a plurality of orders can be processed simultaneously by one multi-picking cart 30, the effectiveness of the multi-picking cart 30 on which a plurality of containers can be placed can be used more effectively.

  By the way, if the storage shelf aisle where the goods to be picked are stored cannot be entered due to congestion of another cart or skipped, or if there is no stock in the storage shelf and a replenishment request is made, skip it later An instruction is given to pick the product again and put it into a predetermined container. That is, there is no change in the container to be input. If there is an error in the volume calculation, add the container at the operator's discretion, or if the maximum loading weight of the container is determined, add the container when the weighing instrument exceeds the weight threshold stored in the initial settings. Can also be notified. If the measuring device is not mounted on the mounting table, rely on the operator's judgment as to whether the corresponding container can be carried, or create a work instruction considering the weight when calculating the capacity / volume.

  By the way, when determining the combination of containers according to the operation flow shown in FIG. 9, the number of containers required for one transaction (the number of unprocessed containers) is more than the number of mountable platforms. For example, if the number is 10, 4 → 4 → 2 is specified. In other words, the designation means (such as the CPU 11 that executes steps ST1-1 to ST1-8) determines that the unprocessed container quantity of the containers required for the one transaction is equal to the quantity of mountable platforms. In the case of the same or more, the unprocessed containers are designated for all the mounting tables that can be placed as described above. Therefore, the unprocessed containers necessary for one transaction can be efficiently integrated together. It can be carried on a table cart (multi-picking cart) 30. In this example, when one transaction is repeatedly processed by the same cart 30, the total number of total containers required for the one transaction is 10 when starting the picking operation (before). Is displayed on the display unit (output unit) 39 or printed by the printing unit (output unit) 47, it is necessary in advance by grasping the total number of containers when starting work. This is particularly suitable because several containers can be prepared. When the last two are specified, two mounting tables 33 are vacant, so that a transaction container that requires two of the other transactions is specified. If there are no other transactions that require two containers, specify one other transaction that requires one, otherwise, select some of the other transactions that require three or more containers. A container will be specified.

  In the above example, the example in which the product is input into the container C1 after the product input into the containers A1 to A3 is completed is shown, but parallel picking may be performed with respect to containers for different orders. FIG. 12 is a diagram illustrating an example of operation screens G9 to G11 displayed on the display unit 39 of the cart 30 when products are picked in parallel in the containers A1 and A3 and the container C1. That is, in the case of this example, the container A1 is placed on the placing table 33-1 and the container C1 is also placed on the placing table 33-4, and the common product (2) is picked in parallel (simultaneously). At this time, as shown in FIG. 12A, the operation screen G9 displays that the product (2) is picked in parallel with the containers A1 and C1. Similarly, the common product (4) is picked in parallel. At this time, as shown in FIG. 12B, the operation screen G10 displays that the product (4) is picked in parallel with the containers A1 and C1. Similarly, the common product (7) is picked in parallel. At this time, as shown in FIG. 12C, the operation screen G11 is displayed to pick the product (7) in parallel with the container A3 and the container C1. With this configuration, when each product is picked into the containers A1 to A3, the product can be picked into the container C1 in parallel with this, and an efficient picking operation can be performed.

  FIG. 8 shows an example of the quantity of containers for each order A, B, C, and D shown in FIG. 6 in which the types of containers placed on the plurality of placement tables 33-1 to 3-4 are prioritized in the conventional picking efficiency. It is a figure which shows the installation state of each container to each mounting base 33-1-4 when determined by the method. When a container is selected with priority on picking efficiency (flow line), it is more efficient to pick up the product at the same time for a plurality of containers into which the same product is placed. Therefore, in this example, the containers A1, B1, and D1 that need to pick up the product (1) are selected, and then the container C1 that needs to pick up the product (2) is selected. As a result, at the stage of picking by the cart 30, when picking goods (1), (2), (3), (4) for the container A1, these goods are also put into the containers B1, D1, C1 at the same time. It can be stored, and the picking of the products (1), (2), (3), (4) can be completed only by moving the cart 30 once, and efficient picking work can be performed. However, when such a picking instruction is issued, the order destinations of the containers A1, B1, C1, and D1 are different from each other, so that the containers after the picking are finished are assigned to the respective orders A, B, C, and D. It is necessary for the operator to collect separately and put it on the delivery route, and the work becomes complicated. On the other hand, if the picking instruction method shown in FIG. 7 is used, since containers of the same order are placed together in the cart 30 after picking, the containers after picking are assigned to the orders A, There is no need for the operator to separately aggregate for each of B, C, and D (or the burden is reduced), and it can be easily placed on the delivery route.

[Pattern 2] When the capacity / volume calculation is not performed by the host system (such as the management apparatus 10) When the capacity / volume calculation is not performed by the host system, the container addition condition is the number of slip lines in the host system (such as the management apparatus 10). And the total number of products or a total of them to set a threshold. That is, when creating the picking instruction data, the picking instruction data is created based on the number of slip lines of one order, the total number of products, or both conditions, instead of the capacity / volume. Also in this case, the containers required for one order are collectively specified as containers to be simultaneously placed on the plurality of placement tables 33-1 to 3-4.

[Pattern 3] When specifying the number of mounted units to be used from the cart 30 side In this case, the volume / capacity calculation is assumed. Specifically, for example, two of the mounting tables 33-1 and 3-1, 2 are designated from the cart 30 side, pickup instruction data is received from the management device 10 side, and the products (1) to (6) in the order A are received. Next, one of the mounting tables 33-3 is designated from the cart 30 side, pick-up instruction data is received from the management device 10 side, the products (7) and (8) in the order A are picked up, Since the rest of the mounting table 33-4 automatically remains, the pick-up instruction data is received from the management apparatus 10 side, and the products (2), (4), (7) in the order C are picked up. That is, also in this case, the containers A1, A2, A3 and C1 required for one order are collectively designated as containers to be simultaneously placed on the plurality of placement tables 33-1 to 3-4.

  In the above-described embodiment, the four carts 30 are described as the mounting table 33. However, it is sufficient that there are a plurality of mounting tables. It can also be applied to a mechanism using a portable terminal and a cart or a cargo vehicle. A portable shelf that is partitioned into multiple parts can be used instead. A portable terminal (tablet PC or the like) and a portable device that can be partitioned (for example, a car car is divided by a partition plate or the like) can work in the same manner. Equipment that follows and moves automatically may be used.

  In the above embodiment, the container to be placed on the plurality of placement tables is configured to include the designation unit that collectively designates the containers required for each transaction. A designation means for the picking cart may be provided so as to be switchable. Here, the normal multi-picking cart designation means is a designation means that specifies a pattern (work instruction procedure) that optimizes the flow line of the cart, or a pattern that increases the number of opportunities for picking the same product according to location order. It is means (designation means as described with reference to FIG. 8) that prioritizes the efficiency of picking itself, such as designation means that designates (work instruction order). For example, when the number of containers used for one order is less than the maximum number of containers (4 containers) that can be placed in one cart, the specifying means according to the above embodiment (consolidates containers required for each transaction) For example, the number of containers used for one order exceeds the maximum number of containers that can be placed in one cart (5 containers). ) In the above case, the normal (conventional) multi-picking cart designation means can be used for shipping via a sorting device. In this case, the designation means may be automatically switched according to the number of containers used for one order. In addition, when the shipping time is not in time, or further, when the priority is given to work efficiency by analyzing the remaining time until the shipping time and the number of remaining instructions, for example, while operating with the specifying means according to the above embodiment, It is also possible to switch to the above conventional designation means (or vice versa) on the way.

  In addition, when equipped with a measuring instrument, the unit weight of the product and the ball unit weight including the ball exterior can be measured and stored during picking. (Many centers have separate storage shelves and picking shelves) and at the same time issue replenishment labels and receipts, and work for once completing work and putting in replenished products It is also possible to issue a label (holding label), a shortage label at the time of shortage, an SCM label specified by a business partner, a location label (receipt) for guiding the location at the time of replenishment of goods.

  In addition, the program executed by the cart 30 and the management device 10 according to the above-described embodiment is provided by being incorporated in advance in the ROM 61, the ROM 15, or the like, but is not limited thereto, and can be installed or executed.
