Description

[Technical Field]

[0001] The present invention relates to a picking system, a picking method, and a picking program for performing picking work to remove an ordered item group consisting of items of the type and number specified by order information from a source item holder and transfer it to a destination item holder. [Background technology]

[0002] For example, Japanese Patent No. 4048426 discloses equipment for performing a picking operation to transfer an item from a source mount to a destination mount. The reference numerals in parentheses in the following description of the background art are those of Patent Document 1.

[0003] The equipment disclosed in Patent Document 1 includes an item storage shelf (3) that stores items placed on pallets (2) and various conveying devices that transport the pallets (2). The pallets (2a) loaded with items are transported from the item storage shelf (3) to a picking location (4). At the picking location (4), as shown in FIG. 3 of the same document, the required number of items are transferred from the multiple pallets (2a) that serve as source storage bodies to an empty pallet (2c) that serves as a destination storage body. After transferring the items to be transferred from the pallets (2a) to the empty pallet (2c), the worker turns on the pick completion button (16) to return the pallet (2a) to the item storage shelf (3). The worker repeats the above process until the required number of items are stored on the empty pallet (2c) at the picking location (4). [Prior art documents] [Patent documents]

[0033] In the picking system 100 according to the present disclosure, when the source object 9s in the source area As is the final order object 9f (see FIG. 4) carrying the last item 90 to be transferred last among the group of ordered items Go to be transferred to the destination object 9d in the destination area Ad, the control device C controls the source object supply device 1 to execute the source object supply process Pss so that a new source object 9s is supplied to the source area As after the start of the destination object carry-out process Pod, which carries the destination object 9d out of the destination area Ad. Note that "after" includes both that point in time and a later point in time. Therefore, the new source object 9s is supplied (arrives) at the source area As at the start of the destination object carry-out process Pod or at a time later than the start of the destination object carry-out process Pod.

[0034] In this way, a source object supply process Pss is executed to supply a new source object 9s to the source area As so that a new source object 9s is supplied to the source area As after the start of the destination object carry-out process Pod for carrying out the destination object 9d on which the final item 90 has been transferred and for which the picking operation has been completed. Therefore, a state in which the destination object 9d on which the picking operation has been completed is in the destination area Ad and the new source object 9s is in the source area As does not continue. For example, if a new source object 9s is supplied to the source area As at a time after the start of the destination object carry-out process Pod, the new source object 9s will not be supplied to the source area As while the destination object 9d on which the picking operation has been completed is in the destination area Ad. Therefore, the picking system 100 according to the present disclosure can prevent the item 90 related to different order information from being mistakenly transferred to the transfer destination mount body 9d for which the picking operation has been completed.

[0035] In this embodiment, the control device C identifies the source placement body 9s required to collect the items 90 included in the ordered item group Go, and if multiple source placement bodies 9s are identified, it determines that the source placement body 9s that is last supplied to the source area As among the multiple source placement bodies 9s is the final placement body 9f of the order.

[0036] For example, FIG. 2 shows a list of source placement objects 9s required to collect the items 90 included in the ordered item group Go related to the order information α. ​​In the illustrated example, the ordered item group Go related to the order information α is composed of items 90 placed on multiple source placement objects A, B, and C. For example, a display unit may be provided in the picking area Ap, and the list may be displayed on the display unit. The list shown in FIG. 2 indicates that the multiple items 90 included in the ordered item group Go related to the order information α can be collected by picking a number of items 90 from the source placement object A, b number of items 90 from the source placement object B, and c number of items 90 from the source placement object C.

[0037] In the example shown in FIG. 2, the control device C identifies source mount bodies A, B, and C required to collect the items 90 (in this example, multiple items 90) included in the order item group Go related to the order information α. ​​When source mount body C is supplied to the source area As first among source mount bodies A, B, and C, worker W removes c items 90 from source mount body C and transfers them to destination mount body 9d. Then, the control device C stores information that the work on source mount body C has been completed. This information may be stored by the operation of worker W. In the example shown, after the work on source mount body C has been completed, "Completed" is entered in the column for source mount body C in the list (see the center diagram in FIG. 2).

[0038] Next, when source body A of the remaining source bodies A and B is supplied to source area As, worker W removes a number of items 90 from source body A and transfers them to destination body 9d. Then, control device C stores information that the work on source body A has been completed. In the illustrated example, after the work on source body A has been completed, "Completed" is entered in the column for source body A in the list (see the right diagram in FIG. 2).

[0039] Then, the control device C determines that the source object B (the last remaining source object B) among the source objects A, B, and C on which no work has been performed is the final order object 9f. When the source object B is supplied to the source area As, the worker W takes out b items 90 from the source object B and transfers them to the destination object 9d. As a result, all of the items 90 making up the ordered item group Go are transferred to the destination object 9d, and the picking work for the destination object 9d is completed.

[0040] The control device C executes different processes depending on whether the source placement object 9s in the source area As is the final placement object 9f of the order or not. FIG. 3 shows the process executed by the control device C when the source placement object 9s in the source area As is not the final placement object 9f of the order. FIG. 4 shows the process executed by the control device C when the source placement object 9s in the source area As is the final placement object 9f of the order. Note that in FIGS. 3 and 4, different numbers (No. 1 to No. 4) are assigned to each placement object 9 to make it easier to distinguish the movement of each of the multiple placement objects 9. Also, the items 90 placed on the placement objects 9 are omitted.

[0041] 3, in this embodiment, when the source placement object 9s (No. 1) in the source area As is not the last placement object 9f of the order, the control device C executes a source placement object carry-out process Pos for carrying out the source placement object 9s (No. 1) from the source area As and a source placement object supply process Pss for supplying a new source placement object 9s (No. 2) to the source area As in parallel. This allows the new source placement object 9s (No. 2) to be supplied to the source area As in parallel with the carrying-out of the source placement object 9s (No. 1) from the source area As, making it easy to quickly start the operation of taking out the required item 90 from the next source placement object 9s (No. 2). In this case, the item 90 is transferred from the new source mount 9s (No. 2) to the destination mount 9d (No. 3) in the destination area Ad, and the picking operation continues. Note that executing multiple processes in parallel means executing these multiple processes so that the execution periods of each process overlap at least partially.

[0042] In this embodiment, when the source placement object 9s (No. 1) in the source area As is not the last placement object 9f of the order, the control device C executes the source placement object carry-out process Pos and the source placement object supply process Pss based on the operation of the take-out completion reception unit 8s (see FIG. 1). That is, when the worker W completes taking out the items 90 included in the ordered item group Go from the source placement object 9s (No. 1) in the source area As, he operates the take-out completion reception unit 8s. Then, the control device C executes the source placement object carry-out process Pos and the source placement object supply process Pss, and swaps the source placement object 9s in the source area As (No. 1 → No. 2). Thereafter, as described above, the picking operation continues to transfer the article 90 from the source receiver 9s (No. 2) in the source area As to the destination receiver 9d (No. 3) in the destination area Ad.

[0043] 4(a) and 4(b), in this embodiment, when the source object 9s (No. 1) in the source area As is the last object 9f of the order, the control device C executes the source object carry-out process Pos, and then executes the destination object carry-out process Pod and the source object supply process Pss in parallel. Specifically, the control device C executes the destination object carry-out process Pod and the source object supply process Pss in parallel so that a new source object 9s is supplied to the source area As after the destination object carry-out process Pod starts to be executed. Because the destination object carry-out process Pod and the source object supply process Pss are executed in parallel in this way, it is possible to prevent a new source object 9s (No. 2) from being supplied to the source area As while the destination object 9d (No. 3) for which picking has been completed remains in the destination area Ad. Therefore, it is possible to prevent the article 90 relating to different order information from being mistakenly transferred to the destination placement body 9d (No. 3) for which the picking operation has been completed.

[0044] 4(b), in this embodiment, the control device C executes a destination object supply process Psd in parallel with the destination object carry-out process Pod, which supplies a new destination object 9d (No. 4) to the destination area Ad. That is, in this example, the control device C executes the destination object carry-out process Pod, the destination object supply process Psd, and the source object supply process Pss in parallel. This makes it possible to avoid erroneous transfer of the item 90 to the destination object 9d (No. 3) for which picking work has been completed, and also makes it possible to quickly replace the destination object 9d with respect to the destination area Ad (No. 3 → No. 4).

[0045] In this embodiment, when the source object 9s (No. 1) in the source area As is the final ordered object 9f, the control device C executes the source object carry-out process Pos (see FIG. 4(a)) based on the operation of the take-out completion reception unit 8s (see FIG. 1), and executes the destination object carry-out process Pod and the source object supply process Pss (see FIG. 4(b)) based on the operation of the picking completion reception unit 8d (see FIG. 1). That is, when the transfer of the ordered item group Go to the destination object 9d (No. 3) is completed, the worker W operates the picking completion reception unit 8d. Then, the control device C executes the destination object carry-out process Pod and the source object supply process Pss. In this embodiment, the control device C executes the destination object carry-out process Pod, the destination object supply process Psd, and the source object supply process Pss based on the operation of the picking completion reception unit 8d. As a result, the destination object 9d (No. 3) for which the picking operation has been completed is carried out from the destination area Ad, a new destination object 9d (No. 4) is supplied to the destination area Ad, and a new source object 9s (No. 2) is supplied to the source area As (see FIG. 4(b)).

[0046] 4(c), after the control device C completes the above series of processes, a new source substrate 9s (No. 2) is placed in the source area As, and a new destination substrate 9d (No. 4) is placed in the destination area Ad. Then, based on different order information, a new picking operation is started for the new destination substrate 9d (No. 4).

[0047] Next, the processing procedure performed by the control device C will be described with reference to the flowchart of FIG.

[0048] As shown in Fig. 5, the control device C determines whether the source object 9s in the source area As is the last object 9f of the order (step #11). After determining that the source object 9s in the source area As is the last object 9f of the order (step #11; Yes), if the removal completion reception unit 8s is operated (step #12; Yes), the control device C executes the source object carry-out process Pos (step #13). Thereafter, if the picking completion reception unit 8d is operated (step #14; Yes), the control device C executes the transfer destination object carry-out process Pod, the transfer destination object supply process Psd, and the source object supply process Pss in parallel (step #15).

[0049] On the other hand, after determining in step #11 that the source object 9s in the source area As is not the final object 9f of the order (step #11; No), if the removal completion reception unit 8s is operated (step #16; Yes), the control device C executes the source object carry-out process Pos and the source object supply process Pss in parallel (step #17).

[0050] Second Embodiment Next, a second embodiment of the picking system 100 will be described. In the second embodiment, the processing performed by the control device C when the source object 9s in the source area As is the final object 9f of the order differs from that of the first embodiment. The following mainly describes the differences between the second embodiment and the first embodiment. Points that are not specifically described are the same as those of the first embodiment.

[0051] In this embodiment, when the source object 9s in the source area As is the last object 9f of the order, the control device C executes the destination object carry-out processing Pod, the source object carry-out processing Pos, and the source object supply processing Pss in parallel. Specifically, the control device C executes the destination object carry-out processing Pod, the source object carry-out processing Pos, and the source object supply processing Pss in parallel so that a new source object 9s is supplied to the source area As after the destination object carry-out processing Pod starts to be executed. Because the destination object carry-out processing Pod, the source object carry-out processing Pos, and the source object supply processing Pss are executed in parallel in this way, it is possible to prevent a new source object 9s from being supplied to the source area As while the destination object 9d for which the picking operation has been completed remains in the destination area Ad. Therefore, it is possible to prevent the transfer of items 90 related to different order information to the transfer destination mount 9d for which picking work has been completed by mistake. In addition, since a new source mount 9s is supplied to the source area As in parallel with the transfer destination mount 9d for which picking work has been completed being transported out of the transfer destination area Ad, it is easy to quickly start picking work for the next group of ordered items Go.

[0052] In this embodiment, when the source object 9s in the source area As is the final object 9f, the control device C executes the destination object carry-out process Pod, the source object carry-out process Pos, and the source object supply process Pss based on the operation of the take-out completion acceptor 8s. That is, when the worker W completes the transfer of the group of ordered items Go to the destination object 9d, he operates the take-out completion acceptor 8s instead of the picking completion acceptor 8d. Then, the control device C executes the destination object carry-out process Pod, the source object carry-out process Pos, and the source object supply process Pss. Note that in this embodiment, the operation unit 8 does not have to be equipped with the picking completion acceptor 8d.

[0053] Next, the processing procedure performed by the control device C will be described with reference to the flowchart of FIG.

[0054] 6, the control device C determines whether the source object 9s in the source area As is the last object 9f of the order (step #21). After determining that the source object 9s in the source area As is the last object 9f of the order (step #21; Yes), if the removal completion reception unit 8s is operated (step #22; Yes), the control device C executes the destination object carry-out process Pod, the destination object supply process Psd, the source object carry-out process Pos, and the source object supply process Pss in parallel (step #23).

[0055] On the other hand, after determining in step #21 that the source object 9s in the source area As is not the final object 9f of the order (step #21; No), if the removal completion reception unit 8s is operated (step #24; Yes), the control device C executes the source object carry-out process Pos and the source object supply process Pss in parallel (step #25).

[0056] [Picking method and picking program] According to the picking system 100 described above by exemplifying the first and second embodiments, it is possible to prevent the item 90 from being mistakenly transferred to the destination receiver 9d for which the picking operation has been completed. The configuration of the picking system 100 described above can also be used for a picking method or a picking program.

[0057] In other words, the picking method is a method for performing picking work in which an order item group Go consisting of items 90 of the type and number specified by order information is picked from a source item holder 9s placed in a source area As, which holds a single item group Gs consisting of multiple items 90 of the same type, and is transferred to a destination item holder 9d placed in a destination area Ad.

[0058] This picking method includes a source object supplying step of supplying a source object 9s to the source area As, a source object carrying step of carrying the source object 9s from the source area As, and a destination object carrying step of carrying a destination object 9d from the destination area Ad. In the picking method, if the source object 9s in the source area As is a final order object 9f carrying the last item 90 of the group of ordered items Go to be transferred to the destination object 9d in the destination area Ad, the source object supplying step is executed so that a new source object 9s is supplied to the source area As after the start of the destination object carrying step of carrying the destination object 9d from the destination area Ad. The picking method according to the present disclosure further includes a destination object supplying step of supplying the destination object 9d to the destination area Ad.

[0059] In addition, the picking program is a program for performing picking work to pick out an order item group Go consisting of items 90 of the type and number specified by order information from a source item group Gs consisting of multiple items 90 of the same type and placed in the source area As, and transfer it to a destination item group 9d placed in the destination area Ad.

[0060] This picking program enables the computer to realize a source body supply function that causes the source body supply device 1 to perform a source body supply process that supplies the source body 9s to the source area As, a source body carry-out function that causes the source body carry-out device 2 to perform a source body carry-out process that carries the source body 9s out of the source area As, and a destination body carry-out function that causes the destination body carry-out device 4 to perform a destination body carry-out process that carries the destination body 9d out of the destination area Ad. Then, when the source object 9s in the source area As is the final order object 9f carrying the final item 90 to be transferred last among the group of ordered items Go to the destination object 9d in the destination area Ad, the picking program executes a source object supply process so that a new source object 9s is supplied to the source area As after the start of the destination object carry-out process for carrying the destination object 9d out of the destination area Ad. The picking program according to the present disclosure also causes the computer to realize a destination object supply function for causing the destination object supply device 3 to perform the destination object supply process for supplying the destination object 9d to the destination area Ad. The picking program is provided, for example, by a recording medium (a computer-readable recording medium such as an optical disk or flash memory) on which the picking program is recorded, or via a communication network. The provided picking program is stored in a computer-accessible storage device. In this embodiment, the control device C (specifically, the arithmetic processing device included in the control device C) functions as a "computer."

[0061] Other Embodiments Next, other embodiments of the picking system, the picking method, and the picking program will be described.

[0062] (1) In the above embodiment, an example has been described in which the control device C, when the source placement object 9s in the source area As is not the last placement object 9f of the order, executes in parallel the source placement object carry-out process Pos for carrying the source placement object 9s out of the source area As and the source placement object supply process Pss for supplying a new source placement object 9s to the source area As. However, without being limited to this example, the control device C may execute the source placement object carry-out process Pos and the source placement object supply process Pss at different times even when the source placement object 9s in the source area As is not the last placement object 9f of the order.

[0063] (2) In the above embodiment, an example has been described in which the control device C executes the destination object supply process Psd in parallel with the destination object carry-out process Pod to supply a new destination object 9d to the destination area Ad. However, the control device C may execute the destination object carry-out process Pod and the destination object supply process Psd at different times.

[0064] (3) In the above embodiment, an example has been described in which the source body supply process Pss, the source body carry-out process Pos, the destination body supply process Psd, and the destination body carry-out process Pod are executed based on the operator W operating the operation unit 8. However, the present invention is not limited to this example, and the control device C may automatically execute each process without the operator W's input. In this case, the operation unit 8 is not required.

[0065] (4) In the above embodiment, an example has been described in which the source object supply device 1, the source object carry-out device 2, the destination object supply device 3, and the destination object carry-out device 4 are configured using conveyors. However, without being limited to this example, each of the above devices may be a device that continuously transports multiple objects 9 along the same path, such as a lifter that transports the objects 9 in a vertical direction or a transport device that transports the objects 9 in a circular motion around a horizontal axis.

[0066] (5) In the above embodiment, an example has been described in which the picking system 100 further includes a destination object supply device 3 that supplies the destination object 9d to the destination area Ad. However, the present invention is not limited to this example, and the picking system 100 does not necessarily have to include the destination object supply device 3. In this case, the destination object 9d may be supplied to the destination area Ad by, for example, an operator W.

[0067] (6) The configurations disclosed in the above-described embodiments may be combined with configurations disclosed in other embodiments as long as no contradictions arise. Regarding other configurations, the embodiments disclosed in this specification are merely examples in all respects. Therefore, various modifications may be made as appropriate within the scope of the present disclosure.
