Description

[Technical Field]

[0001] The present invention relates to a work facility that includes an item placement device having multiple item placement areas in each of which items are placed, and a work support device that provides work support to workers who work on the items placed in the multiple item placement areas. [Background technology]

[0002] An example of such work equipment is the equipment disclosed in Japanese Patent Laid-Open No. 2018-154502 (Patent Document 1). In the following description of the background art, the reference numerals in parentheses refer to those in Patent Document 1.

[0003] The facility disclosed in Patent Document 1 is provided with a storage shelf (2) storing a plurality of containers (3). A worker performs a designated task for each of the plurality of containers (3). In this facility, an instruction device (11) supports the worker's work. Specifically, the instruction device (11) indicates to the worker which container (3) to work on by irradiating light onto an area on the storage shelf (2) where the containers (3) are arranged. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Publication No. 2018-154502 Summary of the Invention [Problem to be solved by the invention]

[0005] Incidentally, the position of the light (illumination position) emitted by the indicating device (11) indicates the container (3) to be worked on, and therefore needs to be set to an appropriate position relative to the placement area where the container (3) is placed. However, the position of the placement area for each container (3) on the storage shelf (2) is not always constant, and the size and placement pattern of the container (3) may change. In such cases, the position of the light emitted by the indicating device (11) may deviate from the placement area where the container (3) is actually stored, and therefore the illumination position needs to be reset. It is desirable to set the illumination position not only so that it corresponds to the placement area where the container (3) is stored, but also to make it as easy as possible.

[0006] In view of the above circumstances, it is desirable to realize a work facility that allows easy setting of the irradiation position of the indicator light that is irradiated onto the placement area of ​​the item. [Means for solving the problem]

[0007] an item placement device in which a plurality of item placement areas are set, in which items are placed; a work support device that provides work support to a worker who works on the items placed in the plurality of item placement areas; A work facility comprising: The work assistance device includes: an illumination device that illuminates areas of the item placement device corresponding to each of the plurality of item placement areas with indication light that indicates the item placement area to be worked on; a control system including an input reception terminal that receives input from an administrator; Equipped with the input receiving terminal includes a display unit that displays an image, and an input unit that receives an operation input for the image displayed on the display unit; The control system includes: a position setting mode for setting irradiation positions of the indicator lights indicating each of the plurality of item placement areas; In the position setting mode, a layout diagram showing the arrangement of the multiple item placement areas is displayed on the display unit, and when an instruction to change the layout diagram is received from the input unit, the layout diagram is changed in accordance with the change instruction, and the irradiation position is set to match the changed layout diagram.

[0008] According to this configuration, in the position setting mode, the manager can set the irradiation position of the instruction light for each of the multiple item placement areas by using the input receiving terminal to input an instruction to change the layout diagram displayed on the display unit. At this time, the layout diagram showing the layout of the multiple item placement areas is displayed on the display unit of the input receiving terminal, so the manager can give the instruction to change while checking the layout diagram. Therefore, according to this configuration, it is possible to easily change the setting of the irradiation position of the instruction light irradiated on the item placement areas.

[0009] Further features and advantages of the techniques according to the present disclosure will become more apparent from the following description of exemplary and non-limiting embodiments, which proceeds with reference to the drawings. [Brief explanation of the drawings]

[Figure 4] FIG. 10 is a diagram showing an example of an input reception terminal. [Figure 5] Position setting mode illustration [Figure 6] Position setting mode illustration DETAILED DESCRIPTION OF THE INVENTION

[0011] Hereinafter, an embodiment of the work equipment will be described with reference to the drawings.

[0012] As shown in Figure 1, the work equipment 100 includes an item placement device 1 having multiple item placement areas 10 in each of which items 9 are placed, and a work support device 2 that provides work support to a worker 8 who works on the items 9 placed in the multiple item placement areas 10.

[0013] In this embodiment, the item placement device 1 is a shelf configured with multiple levels. The multiple item placement areas 10 are set to be aligned along a predetermined arrangement direction X.

[0014] In this embodiment, multiple item placement areas 10 are set on each tier of the item placement device 1. That is, in this embodiment, the "arrangement direction X" is a direction (e.g., horizontal) that intersects with the vertical direction. In this example, each tier of the item placement device 1 is not physically partitioned. The size of the item placement area 10 set on each tier depends on the size of the items 9 to be placed there. Note that when multiple item placement areas 10 are set side by side in the vertical direction, the "arrangement direction X" becomes the vertical direction.

[0015] In this embodiment, the items 9 include containers 90 and items 9a stored in the containers 90. In this embodiment, "work on items" includes work to remove the items 9a from the containers 90 (picking work) and work to store the items 9a in the containers 90 (assorting work). Examples of the items 9a include finished products and semi-finished products. Here, an example will be described in which the items 9a are goods. That is, in this example, one or more goods 9a are stored in the containers 90 and placed on the item placement device 1. However, the goods 9a may also be placed directly on the item placement device 1 without being stored in the containers 90.

[0016] The order information is information indicating the type and number of items 9 required for each shipping destination, and the picking work by the worker 8 is performed based on the order information. That is, the worker 8 picks one or more items 9 (products 9a) specified in the order information.

[0017] In this embodiment, the work equipment 100 includes a temporary storage shelf 3 on which one or more items 9 picked by the work of a worker 8 are temporarily placed, and a transport device 4 that transports the one or more items 9 placed on the temporary storage shelf 3. In this example, the transport device 4 is configured to transport a shipping container 7. The items 9 are transported by the transport device 4 while contained in the shipping container 7. In the illustrated example, the transport device 4 is configured using a conveyor. However, the transport device 4 is not limited to this, and may also be configured using an automated guided vehicle, a rail-guided vehicle, or the like.

[0018] As shown in Fig. 2, a worker 8 performs picking work to place multiple products 9a related to order information on the temporary shelf 3. In this embodiment, the temporary shelf 3 is provided with an item storage section 30 in which the products 9a taken out by the picking work are collected and stored according to the order information. The temporary shelf 3 is provided with multiple item storage sections 30, and each of the multiple item storage sections 30 is provided with a collection display device 31 that indicates whether or not collection is in progress.

[0019] In the example shown in Figure 2, the number of products 9a specified by the order information is "5", and five products 9a are stored in the product storage section 30. The collection display device 31 provided in the product storage section 30 displays "5", and in this example, the collection display device 31 indicates that collection has been completed.

[0020] When the shipping container 7 is transported by the transport device 4 to the vicinity of the temporary storage shelf 3, the worker 8 places the multiple products 9a related to the order information placed on the temporary storage shelf 3 into the shipping container 7. Then, the transport device 4 transports the shipping container 7 to the location where the next process will be performed.

[0021] 1, the work support device 2 includes an illumination device 20 that illuminates areas corresponding to each of the multiple item placement areas 10 in the item placement device 1 with an indication light 20a that indicates the item placement area 10 to be worked on. The area illuminated by the indication light 20a may be the item placement area 10 itself, a position outside the item placement area 10 (part of the front and upper surface of the shelf on which the item 9 is placed), or the item 9 itself placed in the item placement area 10. In this embodiment, the indication light 20a is a spotlight.

[0022] In this embodiment, when there are multiple items 9 related to the order information, the illumination device 20 illuminates the item placement area 10 in which the items 9 to be worked on are placed sequentially or multiple items simultaneously based on the order information. When there is only one item 9 related to the order information, the illumination device 20 illuminates only the item placement area 10 in which that item 9 is placed.

[0023] 3, in this embodiment, the illumination device 20 illuminates the center or near the center of the item placement area 10 in which the item 9 to be worked on is placed. This allows the worker 8 to clearly grasp the item placement area 10 based on the illumination position P20 illuminated by the instruction light 20a. The worker 8 works on the item 9 according to the illumination position P20 illuminated by the instruction light 20a.

[0024] 4, the work support device 2 includes a control system C2 equipped with an input reception terminal 21 that receives input from an administrator. Input to the input reception terminal 21 can also be performed by an on-site worker 8. The input reception terminal 21 is configured using a tablet terminal, a personal computer, a smartphone, or the like.

[0025] The control system C2 includes an input device, a storage device that stores information input to the input device, a processing device that retrieves information from the storage device, performs arithmetic processing, and stores the arithmetic results in the storage device, an output device that outputs the arithmetic results stored in the storage device, and a control device that issues commands to each device. In this embodiment, the input receiving terminal 21 is included in the input device. The irradiation device 20 (see FIG. 1) is included in the output device. That is, the content input to the input receiving terminal 21 is output by the irradiation device 20. The control system C2 is configured using one or more CPUs.

[0026] The control system C2 is configured to be able to execute a work support mode that supports the work of the worker 8. In this embodiment, in the work support mode, the control system C2 causes the illumination device 20 to irradiate an instruction light 20a onto the item placement area 10 in which the item 9 related to the order information has been placed. The worker 8 performs work on the item 9 in accordance with this.

[0027] The input receiving terminal 21 includes a display unit 210 that displays an image G, and an input unit 211 that receives an operation input for the image G displayed on the display unit 210. In this embodiment, the input receiving terminal 21 is configured using a touch panel, and the above operation input is performed by touching the display unit 210. That is, in this embodiment, the display unit 210 also serves as the input unit 211. However, the display unit 210 and the input unit 211 may be separate. In this case, the input unit 211 may be configured using a keyboard or a mouse.

[0028] In this embodiment, the display unit 210 is configured to display a layout diagram M (layout map M) showing the layout of the multiple item placement areas 10. The layout diagram M is a schematic diagram showing the positional relationship (arrangement) of the multiple item placement areas 10 and the ratio of the size of the multiple item placement areas 10 in the width direction (arrangement direction X). The layout diagram M can actually show the ratio of the size of the multiple item placement areas 10 in the vertical direction as well as the ratio of the size of the multiple item placement areas 10 in the width direction (arrangement direction X). The layout diagram M includes layout area frames 10g arranged on the display unit 210 corresponding to each position of the multiple item placement areas 10 in the item placement device 1. The layout area frames 10g are green rectangular frames corresponding to each opening. The shape, pattern, and color are free. The layout diagram M also includes a mark indicating the irradiation position P20 of the instruction light 20a (hereinafter simply referred to as the "irradiation position P20"). The mark may be a simple line or various shapes.

[0029] In this embodiment, information indicating the coordinates of each of the multiple item placement areas 10 (coordinate information Ia), information on the items 9 placed in each of the multiple item placement areas 10 (item information Ib), and information on the indicator light 20a irradiated onto each of the multiple item placement areas 10 (illumination information Ic) are displayed in placement area frames 10g corresponding to each of the multiple item placement areas 10 in the layout drawing M.

[0030] The coordinate information Ia is information that indicates the position of the item placement area 10 in the item placement device 1. The worker 8 can easily grasp the position of the item placement area 10 by referring to the coordinate information Ia displayed in the placement area frame 10g. For example, the row (vertical position) and column (horizontal position) on which the target item placement area 10 is placed are included in the coordinate information Ia.

[0031] The item information Ib is information indicating at least one of the name, type, identification code, and quantity of the item 9. By referring to the item information Ib displayed in the placement area frame 10g, the worker 8 can easily understand the name, type, identification code, quantity, etc. of the item 9 placed in the item placement area 10. For example, the item information Ib includes information such as what kind of product 9a is contained in the container 90 placed in the item placement area 10, or how many of the products 9a are contained therein.

[0032] The illumination information Ic is information indicating the aspect of the indicator light 20a illuminated by the illumination device 20. The operator 8 can easily understand the aspect of the indicator light 20a by referring to the illumination information Ic displayed in the arrangement area frame 10g. For example, the size, shape, etc. of the indicator light 20a are included in the illumination information Ic.

[0033] Here, the position of the illumination device 20 that illuminates the instruction light 20a is fixed (see FIG. 1). In this embodiment, the illumination device 20 can illuminate the instruction light 20a from the fixed position onto any of the multiple item placement areas 10 set in the item placement device 1. Therefore, depending on the position of the item placement area 10 onto which the instruction light 20a is illuminated, the illumination angle of the instruction light 20a from the illumination device 20 increases. The larger the illumination angle of the instruction light 20a, the more distorted the shape of the instruction light 20a projected onto the item placement area 10 becomes, and the larger the projection range of the instruction light 20a becomes.

[0034] Therefore, in this embodiment, the shape and size of the emitted instruction light 20a are set for each of the multiple item placement areas 10. For example, if the irradiation angle of the instruction light 20a is larger than the standard, it is conceivable to set the size of the emitted instruction light 20a to be smaller than the standard.

[0035] Furthermore, when the shape of the instruction light 20a projected onto the item placement area 10 where the irradiation angle of the instruction light 20a is a standard angle is set to a perfect circle, the larger the irradiation angle of the instruction light 20a in the horizontal direction, the more the shape of the instruction light 20a projected onto the item placement area 10 becomes an ellipse that widens in the horizontal direction. In this case, by setting the shape of the instruction light 20a to an ellipse that widens in the vertical direction, the shape of the instruction light 20a actually projected onto the item placement area 10 can be made to be close to a perfect circle.

[0036] Here, the articles 9 placed on the article placement device 1 vary in size and shape. Therefore, for example, when a replenishment operation is performed in which an old article 9 placed on the article placement device 1 is replaced with a new article 9, the irradiation position P20 of the instruction light 20a may shift. This is because the irradiation position P20 of the instruction light 20a, which was set corresponding to the old article 9, does not correspond to the new article 9.

[0037] Therefore, the control system C2 is configured to be able to execute a position setting mode in which an irradiation position P20 of the indicator light 20a indicating each of the multiple item placement areas 10 is set. In the position setting mode, the control system C2 displays a layout diagram M indicating the layout of the multiple item placement areas 10 on the display unit 210, and when an instruction to change the layout diagram M is received from the input unit 211, the control system C2 changes the layout diagram M in accordance with the change instruction and sets an irradiation position P20 to match the changed layout diagram M. The setting of the irradiation position P20 is performed for each of the multiple placement area frames 10g in the changed layout diagram M. For example, when the irradiation position P20 is set to a position that has a predetermined positional relationship with respect to the item placement areas 10, the control system C2 sets the changed irradiation position P20 of the layout diagram M for each of the multiple item placement areas 10 so that the positional relationship is maintained before and after the change to the layout diagram M. The above positional relationship is, for example, a positional relationship in which the item placement areas 10 are placed at a predetermined position (e.g., a central position) in the arrangement direction X of the item placement areas 10.

[0038] This allows the irradiation position P20 of the instruction light 20a to be set so as to correspond to the item 9 currently placed on the item placement device 1. The setting of the irradiation position P20 can be changed using the input reception terminal 21. When changing the setting of the irradiation position P20, a layout diagram M showing the layout of the multiple item placement areas 10 is displayed on the display unit 210 of the input reception terminal 21, so the manager can give instructions for changes while checking the layout diagram M.

[0039] In this embodiment, in the position setting mode, when the input unit 211 receives the designation of one of the multiple item placement areas 10, the illumination device 20 illuminates the area corresponding to the designated item placement area 10 with the instruction light 20a. That is, the instruction light 20a is actually illuminated. With this configuration, the manager can designate the target item placement area 10 and check the actual illumination position P20 of the instruction light 20a corresponding to the item placement area 10. The "designation of the item placement area 10" may be performed by touching the placement area frame 10g displayed on the display unit 210, or by inputting the entrance number corresponding to the desired item placement area 10. When multiple item placement areas 10 are designated, the illumination device 20 may illuminate multiple item placement areas 10 simultaneously.

[0040] In this embodiment, in the position setting mode, the control system C2 displays information (item information Ib) of the items 9 placed in each of the multiple item placement areas 10 in the placement area frame 10g corresponding to each of the multiple item placement areas 10 in the placement plan M. This makes it easier for the manager to check the information of the items 9 placed in each of the multiple item placement areas 10 while the position setting mode is being executed. Note that in the position setting mode, the control system C2 may also display coordinate information Ia and illumination information Ic in the placement area frame 10g in addition to the item information Ib. In this example, each of these pieces of information is displayed in the placement area frame 10g regardless of whether the position setting mode is being executed or not.

[0041] The change instructions accepted in the position setting mode include an instruction to change the size of the item placement area 10 (placement area frame 10g) and an instruction to change the position of the item placement area 10 (placement area frame 10g).

[0042] In this embodiment, the layout drawing M shows a boundary position B sandwiched between two adjacent item placement areas 10 (placement area frames 10g) in the arrangement direction X. The change instruction received in the position setting mode includes an instruction to change the boundary position B. In this example, by changing the boundary position B sandwiched between the two adjacent item placement areas 10 (placement area frames 10g), the sizes of these two item placement areas 10 (placement area frames 10g) are changed.

[0043] 5 and 6 show changes in the layout plan M when an instruction to change the boundary position B is input. The instruction to change the boundary position B is given by moving the boundary position B displayed on the display unit 210. The boundary position B is moved by tracing the screen of the input receiving terminal 21, which is configured as a touch panel, with a finger. Alternatively, the boundary position B can be moved by dragging it with a mouse.

[0044] As shown in the upper diagram of FIG. 5, consider a case where the item placement area 10 in which the items 9 are actually placed does not match the item placement area 10 (placement area frame 10g) shown on the layout drawing M. As described above, such a case can occur when the item placement device 1 is being refilled with items 9. Since the irradiation position P20 of the instruction light 20a is defined by the layout drawing M, in such a case, the irradiation position P20 will be misaligned with respect to the item placement area 10 in which the items 9 are actually placed.

[0045] The lower diagram in FIG. 5 shows a state in which the boundary position B has been changed in the position setting mode. The control system C2 changes the sizes of the two item placement areas 10 (placement area frames 10g) that sandwich the boundary position B in accordance with the change in boundary position B. In the example shown, by moving the boundary position B toward the left in the diagram, the size of the item placement area 10 (placement area frame 10g) located on the leftmost side is changed to be smaller to match the actual item placement area 10. Accordingly, the irradiation position P20 of the instruction light 20a that is irradiated onto the leftmost item placement area 10 (placement area frame 10g) is moved on the layout drawing M to match the position and size of the item placement area 10 (placement area frame 10g). The irradiation position P20 on the layout drawing M is reflected in the irradiation position P20 of the instruction light 20a that is irradiated onto the actual item placement area 10. In other words, the control system C2 sets the irradiation position P20 to match the arrangement of the item placement area 10 defined by the boundary position B after the change in the layout drawing M.

[0046] FIG. 6 shows a case where the above operations and settings are performed on the item placement area 10 (placement area frame 10g) located second from the left in the drawing.

[0047] By performing the same operations and settings for all item placement areas 10 (placement area frames 10g), the item placement areas 10 in which the items 9 are actually placed will be aligned with the item placement areas 10 (placement area frames 10g) shown on the layout drawing M. This makes it possible to irradiate the instruction light 20a to the irradiation position P20 that matches the actual item placement area 10.

[0048] As described above, at least one of the size and shape of the emitted indicator light 20a is set for each of the multiple item placement areas 10. This setting can also be changed in the position setting mode. That is, the control system C2 is configured to be able to set at least one of the size and shape of the emitted indicator light 20a for each of the multiple item placement areas 10 in the position setting mode.
