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] For example, Japanese Patent Laid-Open Publication No. 2003-118814 (Patent Document 1) discloses a technology for managing products stored in a logistics center by the width of each storage shelf. In the following description of the background art, the reference numerals in parentheses refer to those in Patent Document 1.

[0003] In the technology disclosed in Patent Document 1, a shelf information management computer (3) creates storage shelf information and manages products. The storage shelf information includes the storage shelf area, storage shelf number, number of shelves, opening position, product code, product name, etc. This makes it possible to know which product should be stored in which opening on the storage shelf, or which product is stored in which opening. For example, a certain opening is specified from multiple openings on the storage shelf, and a worker performs picking work, such as removing products placed in the specified opening. In this case, the worker's work is performed based on the storage shelf information. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2003-118814 Summary of the Invention [Problem to be solved by the invention]

[0005] Here, it is conceivable to support the work of workers by displaying storage shelf information in the openings (item placement areas) where items are placed. However, when multiple types of items with different dimensions are stored in a storage shelf, the size of the item placement area may differ depending on the dimensions of the items, and the range in which the storage shelf information is displayed may also differ depending on the size of the item placement area. In order to properly support the work of workers in such cases, it is necessary to set the range in which the storage shelf information is displayed for each of the multiple item placement areas to match the size of the item placement area. However, setting this for each of the multiple item placement areas is time-consuming.

[0006] In view of the above situation, it is desirable to realize a technology that allows easy setting of the image display range of the support image corresponding to each of a plurality of item placement areas. [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 plurality of item placement areas are set to be aligned along a predetermined arrangement direction, The work assistance device includes: a display device that displays, in a display area set to extend along the arrangement direction, support images that are images for supporting the work corresponding to each of the plurality of item placement areas; a control system configured to be able to refer to type-specific dimension information indicating dimensions for each type of the article; Equipped with The control system includes: a display range setting process for setting an image display range in the display area, the range being a range in which the support image corresponding to each of the plurality of item placement areas is displayed; In the display range setting process, at least one of the position and dimension in the arrangement direction of each of the multiple image display ranges, and the position and dimension in the arrangement direction of a boundary range sandwiched between two adjacent image display ranges in the arrangement direction is set based on the number of item placement areas lined up in the arrangement direction, the type of item to be placed in each item placement area, and the type-specific dimension information.

[0008] According to this configuration, the image display range of the support image corresponding to each of the multiple item placement areas set in the item placement device can be set all at once by executing a display range setting process, without the administrator having to set each one individually. Furthermore, in this case, the control system executes the display range setting process using item dimension information included in the type-specific dimension information according to the type of item to be placed in each item placement area, so that the image display range of the support image can be set to an appropriate range according to the dimensions of the item to be placed in each item placement area. Therefore, according to this configuration, the image display range of the support image corresponding to each of the multiple item placement areas can be easily set.

[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]

[0010] [Figure 1] Side view of the item placement device [Figure 2] Front view of the item placement device [Figure 3] A perspective view of an article [Figure 4] Control Block Diagram [Figure 5] Illustration of display range setting process [Figure 6] Explanation of setting change process 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 tiers. As shown in FIG. 2, the multiple item placement areas 10 are set to be lined up along a predetermined arrangement direction X. 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., a horizontal direction) 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 areas 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 to be lined up in the vertical direction, the "arrangement direction X" becomes the vertical direction.

[0014] 1, the work performed on the items 9 includes a picking operation of removing the items 9 from the item placement area 10 and a replenishment operation of replenishing the items 9 in the item placement area 10. In the example shown in FIG. 1, the worker 8 is performing the picking operation.

[0015] In this embodiment, the item 9 includes a container 90 and an object 9a contained in the container 90. Examples of the object 9a include finished products and semi-finished products. Here, an example will be described in which the object 9a is a commodity. That is, in this example, one or more items 9a are contained in a container 90 and placed on the item placement device 1. However, the item 9a may also be placed directly on the item placement device 1 without being contained in a container 90.

[0016] The order information is information indicating the type and number of products 9a 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 products 9a specified in the order information.

[0017] In this embodiment, the work equipment 100 includes a conveying device 3. The conveying device 3 is configured to convey a shipping container 7. Products 9a are contained in the shipping container 7 and are conveyed by the conveying device 3. When the shipping container 7 is conveyed by the conveying device 3 to the vicinity of the item placement device 1, a worker 8 places one or more products 9a related to the order information into the shipping container 7. The conveying device 3 then conveys the shipping container 7 to the location where the next process will be performed.

[0018] In the illustrated example, the transport device 3 is configured using a conveyor. However, without being limited to this example, the transport device 3 may be configured using, for example, an unmanned transport vehicle or a rail-guided vehicle.

[0019] As shown in Fig. 2, the work support device 2 includes a display device 20 (see Fig. 1) that displays support images G, which are images for work support corresponding to each of the multiple item placement areas 10, in a display area 1a that is set to extend along the arrangement direction X. In this embodiment, the display area 1a is provided so that the support images G can be seen from the front side of the item placement device 1 (the side of the area where the worker 8 performs the picking work). An image display range Ag, which is the range in which the display device 20 displays the support images G, is set by a control system C2, which will be described later.

[0020] In this embodiment, a sheet-like member is provided on each tier of the item placement device 1. The sheet-like member is oriented with its sheet surface facing the front side of the item placement device 1. The display area 1a described above is set on the sheet surface of the sheet-like member. The display device 20 is configured to display the support image G on this sheet surface (display area 1a). That is, in this embodiment, the display device 20 is configured using a projector. Note that a plurality of vertical slits are formed in the lower part of the sheet-like member. By forming such slits in the sheet-like member, it is possible for the worker 8 to insert his or her hands into the item placement area 10, which is partially covered by the sheet-like member.

[0021] The support image G includes instruction content information that indicates the content of the work instructions given to the worker 8. The instruction content information includes the name of the product 9a, an image of the product 9a, an identification code such as a GTIN (Global Trade Item Number), and the work quantity (the amount of product 9a to be taken out and the amount of product 9a to be put in).

[0022] As shown in FIG. 3, the article 9 includes a rectangular parallelepiped container 90 and one or more products 9a contained in the container 90. The container 90 is, for example, a cardboard box. The articles 9 are arranged in the article arrangement device 1 in a so-called cut display, with only the lid of the container 90 cut off to expose the products 9a inside the container 90. Multiple types of articles 9 are arranged in the article arrangement device 1. The sizes of the articles 9 (the sizes of the containers 90) vary depending on the type. That is, the first width dimension W1 (e.g., horizontal width dimension) and second width dimension W2 (e.g., depth width dimension) of the container 90 differ depending on the type of article 9. Hereinafter, the "dimensions of the container 90" may be simply referred to as the "dimensions of the article 9."

[0023] As shown in Fig. 4, the maintenance facility 100 includes a control system C2 and a database DB. The control system C2 is configured to be able to refer to information stored in the database DB, and to update the information and store it again in the database DB. However, this does not specify the physical configuration. In other words, the control system C2 and the database DB may be configured using the same hardware.

[0024] The control system C2 includes a storage device that stores information input to the input device, an arithmetic processing device that retrieves information from the storage device, performs arithmetic processing, and stores the arithmetic results in the storage device, and a control device that issues commands to each device. In this embodiment, the control system C2 includes an input acceptance terminal 21 that accepts input of a change instruction to change the setting of the image display range Ag (see FIG. 2). This input acceptance terminal 21 is included in the above-mentioned input device. Examples of the input acceptance terminal 21 include a tablet terminal, a PC, and a smartphone. The display device 20 is included in the above-mentioned output device. In other words, the content input to the input acceptance terminal 21 is output by the display device 20. In this way, in this embodiment, the control system C2 is configured to control the display device 20 and the input acceptance terminal 21. The control system C2 is configured using one or more CPUs.

[0025] The information stored in the database DB includes type information Ia indicating the type of item 9, type-specific dimension information Ib indicating the dimensions of each type of item 9, and area dimension information Ic indicating the dimensions of the arrangement direction X of the arrangement area A1 (see FIG. 2). However, the type information Ia and the area dimension information Ic are not necessarily required information. The arrangement area A1 is an area in the item arrangement device 1 set so that multiple item arrangement areas 10 are lined up along the arrangement direction X. In other words, an arrangement area A1 is set on each tier of the item arrangement device 1, and the area including multiple item arrangement areas 10 lined up on each tier in the arrangement direction X is the arrangement area A1.

[0026] The type information Ia is set for each item 9 and includes information about the type of item 9 and information about the quantity of the item 9. When the items 9 to be placed in each item placement area 10 are determined, type information Ia is associated with each item placement area 10.

[0027] The type-specific dimension information Ib is set for each type of item 9 and includes information regarding the dimensions of the item 9, in this case, information regarding the first width dimension W1 and the second width dimension W2 (see FIG. 3). When the type of item 9 to be placed in each item placement area 10 is determined, type-specific dimension information Ib is associated with each item placement area 10. In this embodiment, the type-specific dimension information Ib includes information indicating the dimension of the item 9 in the arrangement direction X when placed in the item placement area 10 for each type of item 9. The "dimension of the item 9 in the arrangement direction X when placed in the item placement area 10" may change depending on the orientation of the item 9 placed in the item placement area 10. In other words, depending on the orientation of the item 9, both the first width dimension W1 and the second width dimension W2 may be the "dimension of the item 9 in the arrangement direction X when placed in the item placement area 10." In addition to this information, the type-specific dimension information Ib may also include information regarding the height of the item 9.

[0028] The area dimension information Ic is set for each of the multiple tiers in the item placement device 1. In the example shown in Fig. 2, the item placement device 1 is configured using multiple tiers of shelves with uniform dimensions in the arrangement direction X, so the area dimension information Ic is the same for each tier. However, this configuration of the item placement device 1 is merely an example. Naturally, if the dimensions in the arrangement direction X differ for each tier, the area dimension information Ic will differ for each tier.

[0029] 4, the control system C2 is configured to be able to refer to type-specific dimension information Ib that indicates the dimensions of each type of item 9. In this embodiment, the control system C2 is also configured to be able to refer to type information Ia and area dimension information Ic.

[0030] 5(a) shows type information Ia and type-specific dimension information Ib. As described above, this information is stored in the database DB, and the control system C2 can refer to this information. In the example shown in the figure, the dimensions (e.g., first width dimension W1) of items 9 of types A, B, C, and D are indicated as Wa, Wb, Wc, and Wd, respectively.

[0031] FIG. 5(b) is a simplified illustration of a portion of the screen of the input receiving terminal 21 used by the worker 8. However, the screen of a management terminal device used by a manager, for example, may also be in this form. The screen visually displays an array area A1 including multiple item placement areas 10 and a setting value of the image display range Ag set by the control system C2. The setting value may be displayed using numbers or letters, or may be displayed using an image of each tier (one tier in the figure) of the item placement device 1, as in the example shown in FIG. 5(b).

[0032] Figure 5(c) corresponds to Figure 5(b), and shows the state in which the support image G is actually displayed in the image display range Ag set by the control system C2. That is, Figure 5(c) shows the state in which the support image G is displayed by the display device 20 on each tier (one tier in the figure) of the item placement device 1.

[0033] As shown in Figure 5, the control system C2 is configured to execute a display range setting process to set an image display range Ag, which is the range in which support images G corresponding to each of the multiple item placement areas 10 in the display area 1a are displayed.

[0034] In the display range setting process, the control system C2 sets at least one of the position and dimension in the arrangement direction X of each of the multiple image display ranges Ag and the position and dimension in the arrangement direction X of a boundary range Ab sandwiched between two image display ranges Ag adjacent to each other in the arrangement direction X, based on the number of item placement areas 10 lined up in the arrangement direction X, the type of items 9 to be placed in each item placement area 10 (type information Ia), and type-specific dimension information Ib. The height dimension of the image display range Ag is set according to the height dimension of each tier of the item placement device 1.

[0035] The size of the item placement area 10 in which the item 9 is placed depends on the dimensions of the item 9. Therefore, for each of the multiple types of items 9, an image display range Ag having a range equivalent in size to the item placement area 10 is set by executing a display range setting process.

[0036] In the display range setting process according to this embodiment, the position of each of the multiple image display ranges Ag in the arrangement direction X is set. The dimension of the image display range Ag in the arrangement direction X is then set based on the dimensions of the article 9. In the example shown in FIG. 5(b), the position of the image display range Ag for article A in the arrangement direction X is set to the leftmost position in the arrangement area A1 in the drawing. The dimension of the image display range Ag in the arrangement direction X is then set to a dimension equivalent to the dimension Wa of article A. The image display ranges Ag for each of articles B, C, and D are set in the same manner. In this way, the image display ranges Ag for all of the articles 9 arranged in the arrangement area A1 are set.

[0037] The image display range Ag for all of the items 9 arranged in the array area A1 can also be set indirectly by setting the position in the array direction X and the dimensions in the array direction X of the boundary range Ab sandwiched between two image display ranges Ag adjacent in the array direction X. Note that the boundary range Ab is a range between two image display ranges Ag adjacent in the array direction X, having an area specified by the position in the array direction X and the width. It can also be called a margin range.

[0038] FIG. 5(b) shows an image display range Ag for each of the four articles 9. A boundary range Ab is located between each image display range Ag, for a total of three boundary ranges Ab. In this embodiment, the dimensions of all boundary ranges Ab in the arrangement direction X are set to be the same. Therefore, by determining the position of each boundary range Ab in the arrangement direction X, the position and dimensions of the image display range Ag for each of the four articles 9 are determined. In the display range setting process, the position of each boundary range Ab in the arrangement direction X is set based on the type-specific dimension information Ib for each article 9. As a result, the image display ranges Ag for all articles 9 arranged in the arrangement area A1 are set, as described above.

[0039] The control system C2 executes the display range setting process, thereby making it possible to collectively set the range (image display range Ag) of the support image G to be displayed in each of the multiple item placement areas 10. Therefore, it is easier to set the image display range Ag than when the manager or worker 8 sets the image display range Ag for each of the multiple item placement areas 10 one by one.

[0040] In this embodiment, the display range setting process is executed during the initial setting of the image display range Ag. For example, the initial setting can be performed by executing the display range setting process when no objects 9 have been placed in the item placement device 1. The placement positions of the objects 9 to be placed on each shelf of the item placement device 1 may have already been determined. In such a case, when no objects 9 have been placed in the item placement device 1, the control system C2 executes the display range setting process to set the range of the support image G (image display range Ag) to be displayed according to the item placement area 10 where each object 9 is to be placed, based on the type information Ia and the type-specific dimension information Ib. Thereafter, when multiple types of objects 9 are placed in the item placement device 1 by the worker 8 or the like, the support image G is displayed in the display area 1a according to the size of the item placement area 10 for each object 9. Note that this initial setting may be performed when objects 9 have been placed in the item placement device 1.

[0041] In this embodiment, the control system C2 executes the display range setting process based on information (area dimension information Ic) indicating the dimensions of the array area A1 in the array direction X. This allows the display range setting process to be executed taking into consideration the amount of margin that will be the spacing in the array direction X between the multiple item placement areas 10. Therefore, it is possible to set multiple image display ranges Ag and multiple boundary ranges Ab in the array area A1 in a well-balanced manner.

[0042] 6(a) and 6(b), there are cases where the image display range Ag set by executing the display range setting process (image display range Ag after initial setting) does not match the size of the item 9 actually placed in the item placement device 1. This can occur when, as described above, the initial setting of the image display range Ag is performed without any item 9 being placed in the item placement device 1. In other words, if, after the initial setting, an item 9 is mistakenly placed in a position different from the set position, the set image display range Ag will not match the size of the item 9 actually placed in the item placement device 1 (the size of the item placement area 10).

[0043] Therefore, in this embodiment, the input receiving terminal 21 (see FIG. 4) is configured to receive input of a change instruction to change the setting of the image display range Ag. The change instruction includes an instruction to change at least one of the position in the arrangement direction X and the dimension in the arrangement direction X of each of the multiple image display ranges Ag, and the position in the arrangement direction X and the dimension in the arrangement direction X of the boundary range Ab sandwiched between two image display ranges Ag adjacent in the arrangement direction X.

[0044] When the input receiving terminal 21 receives a change instruction after executing the display range setting process, the control system C2 executes a setting change process to change the setting of the image display range Ag in accordance with the change instruction.

[0045] Figure 6(a) shows a portion of the screen of the input reception terminal 21 immediately after the display range setting process (initial setting) is executed by the control system C2, and shows the range of the support image G (image display range Ag) displayed for each of the multiple item placement areas 10 included in the array area A1.

[0046] FIG. 6(b) corresponds to FIG. 6(a) and shows a state in which a support image G is actually displayed in the image display range Ag that has been initially set by the control system C2. That is, FIG. 6(b) shows a state in which a support image G is displayed by the display device 20 on each tier (one tier in the figure) of the item placement device 1. In this example, the image display range Ag set by executing the display range setting process (image display range Ag after initial setting) does not match the size of the item 9 actually placed on the item placement device 1. That is, the item placement areas 10 for items A and B do not match the range of the support image G (image display range Ag) displayed corresponding to the item placement area 10. In the example shown, the image display range Ag for item A is larger than the item placement area 10 beyond the margin of error. Furthermore, the image display range Ag for item B is smaller than the item placement area 10 beyond the margin of error. "Beyond the scope of error" means that it is difficult for the worker 8 to clearly understand which item placement area 10 the support image G displayed to assist the worker 8 in his work is being displayed for.

[0047] FIG. 6(c) shows a portion of the screen of the input receiving terminal 21 after the setting change process has been executed by the control system C2. Comparing the actual item placement areas 10 in FIG. 6(b) with the image display ranges Ag after the setting change process in FIG. 6(c), the sizes of the corresponding item placement areas 10 and image display ranges Ag are consistent. This allows the support image G displayed in the image display range Ag to function appropriately to support the work of the worker 8. The setting change process is also executed using the same logic as the display range setting process described above. That is, in the setting change process, the position and size of the image display range Ag may be changed, or the position and size of the boundary range Ab may be changed.

[0048] Other Embodiments Next, other embodiments will be described.

[0049] (1) In the above embodiment, an example has been described in which display device 20 is configured using a projector that displays support image G on the sheet surface of a sheet-like member. However, without being limited to such an example, display device 20 may be configured using a light-emitting device such as an LED or spotlight, or a device that outputs a laser beam, and may display an image of light (support image G) in display area 1 a.

[0050] (2) In the above embodiment, an example has been described in which the item placement device 1 is a shelf configured with multiple tiers. However, the item placement device 1 is not limited to this example, and may be, for example, a support table configured with one tier, or a conveyor having a transport function.

[0051] (3) The configurations disclosed in the above-described embodiments can be applied in combination 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 can be made as appropriate within the scope of the present disclosure.

[0052] [Summary of this embodiment] The summary of this embodiment will be described below.

[0053] 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 plurality of item placement areas are set to be aligned along a predetermined arrangement direction, The work assistance device includes: a display device that displays, in a display area set to extend along the arrangement direction, support images that are images for supporting the work corresponding to each of the plurality of item placement areas; a control system configured to be able to refer to type-specific dimension information indicating dimensions for each type of the article; Equipped with The control system includes: a display range setting process for setting an image display range in the display area, the range being a range in which the support image corresponding to each of the plurality of item placement areas is displayed; In the display range setting process, at least one of the position and dimension in the arrangement direction of each of the multiple image display ranges, and the position and dimension in the arrangement direction of a boundary range sandwiched between two adjacent image display ranges in the arrangement direction is set based on the number of item placement areas lined up in the arrangement direction, the type of item to be placed in each item placement area, and the type-specific dimension information.

[0054] According to this configuration, the image display range of the support image corresponding to each of the multiple item placement areas set in the item placement device can be set all at once by executing a display range setting process, without the administrator having to set each one individually. Furthermore, in this case, the control system executes the display range setting process using item dimension information included in the type-specific dimension information according to the type of item to be placed in each item placement area, so that the image display range of the support image can be set to an appropriate range according to the dimensions of the item to be placed in each item placement area. Therefore, according to this configuration, the image display range of the support image corresponding to each of the multiple item placement areas can be easily set.

[0055] In the item placement device, an area in which the plurality of item placement areas are arranged along the arrangement direction is defined as an arrangement area, It is preferable that the control system further executes the display range setting process based on information indicating the dimensions of the array area in the array direction.

[0056] According to this configuration, since the display range setting process also uses information indicating the dimensions of the array area in the arrangement direction, it is possible to set the position and dimensions of at least one of the image display range and boundary range in the arrangement direction taking into account the amount of margin that will form the spacing between multiple item placement areas in the arrangement direction. This makes it possible to set the image display range and boundary range in a balanced manner within the array area, making it easy to optimize the setting of the position and dimensions of at least one of the image display range and boundary range in the arrangement direction.

[0057] The type-specific dimension information preferably includes, for each type of item, information indicating the dimensions of the item in the arrangement direction when placed in the item placement area.

[0058] According to this configuration, the image display range of the support image can be set to an appropriate range, taking into appropriate consideration the dimensions in the arrangement direction of the items to be placed in each item placement area, based on the information indicating the dimensions in the arrangement direction of the items contained in the type-specific dimension information.

[0059] the control system includes an input receiving terminal that receives an input of a change instruction to change the setting of the image display range, the change instruction includes an instruction to change at least one of the position and the dimension in the arrangement direction of each of the plurality of image display ranges, and the position and the dimension in the arrangement direction of the boundary range sandwiched between two of the image display ranges adjacent in the arrangement direction, Preferably, when the input receiving terminal receives the change instruction after executing the display range setting process, the control system executes a setting change process to change the setting of the image display range in accordance with the change instruction.

[0060] According to this configuration, the image display range setting can be changed after the display range setting process is executed. Therefore, even if the result of the display range setting process cannot be adopted as is for some reason, it is easy to adjust the image display range setting to an appropriate one. [Industrial Applicability]

[0061] The technology disclosed herein can be used in work equipment that includes an item placement device that has 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.
