Description

[Technical Field]

[0001] The present invention relates to a work facility equipped with a work support device. [Background technology]

[0002] A work facility equipped with a work support device is known. JP 2012-162376 A (Patent Document 1) describes a work facility equipped with a work support device (work list issuing machine 18) that issues a work list describing the type and quantity of items to store items from an item placement device (item storage shelf 1) into an item storage container (U) on a manual work cart (20), and supports the target work of a worker. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2012-162376 Summary of the Invention [Problem to be solved by the invention]

[0004] In the above-described work facility, when a worker retrieves an item from an item placement device, the worker needs to check the entries in the work list issued by the work support device. Patent Document 1 does not specifically describe how the worker should check, but it is conceivable that the worker may visually check the entries in the work list. In such a case, the worker needs to visually check the work list against the items to confirm whether or not the items have been retrieved according to the work list. This has limited the improvement of work efficiency.

[0005] Therefore, it is desirable to realize a work facility equipped with a work support device that can easily improve work efficiency. [Means for solving the problem]

[0006] The work equipment disclosed herein is a work equipment comprising: an item placement device having a plurality of item placement areas each having an item placed therein; and a work support device that provides work support to a worker who works on items placed in the plurality of item placement areas, wherein the plurality of item placement areas are set to be aligned along a predetermined arrangement direction, and the work support device comprises: a display device that displays support images for the work corresponding to each of the plurality of item placement areas in display areas provided corresponding to the plurality of item placement areas; a detection device that detects the movement of a worker passing through detection areas set corresponding to each of the plurality of item placement areas; and a control system, wherein the display range of the arrangement direction of the support images corresponding to each of the plurality of item placement areas is set as an arrangement direction display range, and the detection range of the arrangement direction of the detection areas corresponding to each of the plurality of item placement areas is set as an arrangement direction detection range, and the control system sets the arrangement direction display range according to the range of the arrangement direction of the corresponding item placement area, and sets the arrangement direction detection range to be more inward in the arrangement direction than the arrangement direction display range corresponding to the same item placement area.

[0007] According to this configuration, support images corresponding to each of a plurality of item placement areas can be displayed in a range in the arrangement direction corresponding to the corresponding item placement area, and detection areas corresponding to two adjacent item placement areas in the arrangement direction can be spaced apart in the arrangement direction. Therefore, when a worker works on an item placed in one item placement area, the possibility of the worker's movement being erroneously detected in a detection area set corresponding to another adjacent item placement area in the arrangement direction can be reduced. This makes it easier to improve the accuracy of detecting the movement of a worker working on an item placed in an item placement area, and, for example, makes it easier for the detection device to detect whether the worker has worked on the correct item placement area. This makes it easier to improve work efficiency. [Brief explanation of the drawings]

[0018] The work support device 30 includes a support member 31 and a display member 32. The support member 31 supports the display member 32. In this embodiment, the support member 31 is fixed to the item placement device 20, but it may be fixed to a member separate from the item placement device 20. Examples of the support member 31 include part of a pillar of a shelf or building, part of a beam of a shelf or building, part or all of a shelf frame of a shelf, etc. In the example shown in FIG. 1 , the surface of the support member 31 facing the back side X2 is the stop portion 24 described above, and the surface of the support member 31 facing the front side X1 is the mounting portion 37 described below.

[0019] The display member 32 is arranged so that at least a portion thereof is adjacent to the item placement area A1 when viewed from the front side X1. In this embodiment, at least a portion of the display member 32 is arranged on the upper side Z1 of the item placement area A1 when viewed from the front side X1.

[0020] FIG. 3 is a diagram showing an example of a support image D1. The display member 32 has a display area A3. In this embodiment, the display area A3 is a display surface facing the front side X1. A support image D1, which is an image for work support, is displayed in the display area A3. The display area A3 is an area set to extend along the arrangement direction. The display area A3 is arranged so that at least a portion thereof is adjacent to the item placement area A1 when viewed from the front side X1. In this embodiment, the display area A3 is set so that it is adjacent to or overlaps with multiple item placement areas A1. In the example shown, the display area A3 is arranged so that a portion thereof overlaps with the item placement area A1 when viewed from the front side X1. In the example shown, a portion of the display area A3 is arranged above the item placement area A1 when viewed from the front side X1.

[0021] The display member 32 includes a fixed portion 32s fixed to the support member 31. The display member 32 includes a flexible portion 32t that is flexible in the depth direction X. The flexible portion 32t is arranged to extend from the fixed portion 32s toward the item placement area A1. In this embodiment, the extending direction T of the flexible portion 32t is the up-down direction Z, but it may also be the depth direction X or the width direction Y. In the illustrated example, the flexible portion 32t is arranged to extend from the fixed portion 32s downward Z2.

[0022] The fixed portion 32s may be made of the same material as the flexible portion 32t, or may be made of a different material. For example, a member made of the same material as the support member 31 and integral with the support member 31 may function as the fixed portion 32s of the display member 32. For example, the support member 31 may be a pillar or beam of a storage shelf, and the fixed portion 32s of the display member 32 may be a shelf frame of the storage shelf.

[0023] 1, the display member 32 includes a flexible sheet-like member 36. Examples of the sheet-like member 36 include a synthetic resin sheet, a woven fabric, a knitted fabric, a nonwoven fabric, etc. The sheet-like member 36 may be a part of the display member 32, or the sheet-like member 36 may be the display member 32.

[0024] As shown in FIG. 2, the support member 31 has an attachment portion 37 to which the sheet-like member 36 is attached. The attachment portion 37 is arranged to face the front side X1. Examples of the attachment portion 37 include a fastening portion, a fitting portion, an adhesive surface, a hook surface of a hook-and-loop fastener, and the like provided on the support member 31.

The attachment portion 37 and the fixed portion 32s are fixed by a hook-and-loop fastener.

[0025] The flexible portion 32t is a part of the sheet-like member 36. In this embodiment, the flexible portion 32t is a portion of the sheet-like member 36 that extends away from the mounting portion 37. The fixed portion 32s is a part of the sheet-like member 36. The fixed portion 32s is a portion of the sheet-like member 36 that is in contact with and fixed to the mounting portion 37. The flexible portion 32t is a portion that does not contact the mounting portion 37. The length of the flexible portion 32t in the extending direction T may be the same length for the multiple stages of support portions 22 of the item placement device 20, or may be different lengths from each other.

[0026] FIG. 4 is an enlarged view of the display member 32. As shown in FIG. 4, the flexible portion 32t has a notch 39 formed along the extension direction T of the flexible portion 32t from the fixed portion 32s toward the item placement area A1. In this embodiment, the fixed portion 32s does not have the notch 39, but the fixed portion 32s may have the notch 39. In this embodiment, the notch 39 is parallel to the extension direction T of the flexible portion 32t, but may have a direction inclined at an angle between −20 degrees and +20 degrees with respect to the extension direction T. Examples of the width of the notch 39 include approximately zero, 5 mm or less, 10 mm or less, 20 mm or less, and 50 mm or less. As such, the notch 39 may be linear or strip-shaped (slit-shaped).

[0027] The display area A3 of the display member 32 may be provided on both the fixed portion 32s and the flexible portion 32t, or on only one of them. In this embodiment, the display area A3 is provided across the fixed portion 32s and the flexible portion 32t. In the example shown in FIG. 1, the display area A3 provided on the fixed portion 32s is inclined so as to approach the front side X1 as it approaches the lower side Z2.

[0028] As shown in FIGS. 1 and 3, the work support device 30 is equipped with a display device 41 that displays a support image D1, which is an image for work support, in a display area A3. The support image D1 is an image for work support corresponding to each of the multiple item placement areas A1. In this embodiment, the display device 41 displays the same number of support images D1 as the item placement areas A1. In this embodiment, one support image D1 corresponds to one item placement area A1. In other words, one support image D1 is an image for work support for one item placement area A1. The display device 41 displays the support image D1 in the display area A3 of the display member 32 from an upper side Z1 above the item placement area A1.

[0029] Examples of display device 41 include a projection device that projects support image D1 onto display area A3 from front side X1, a projection device that projects support image D1 onto display area A3 from rear side X2, a monitor or display using liquid crystal, organic EL, LED, etc., a light-emitting device using LED, fluorescent tube, etc. Examples of projection devices include a CRT-type projector, a light valve-type projector, a liquid crystal projector, a laser projector, etc.

[0030] The support image D1 includes location identification information that identifies the item placement area A1 where the worker 12 will work from among the multiple item placement areas A1. The display device 41 displays at least a portion of the portion of the support image D1 that represents the location identification information on the flexible section 32t. In this embodiment, the display device 41 displays a location identification image that represents the location identification information on the fixed section 32s and the flexible section 32t. At least a portion of the location identification image is displayed below the instruction content information. In the example shown in FIG. 3, the entire support image D1 is location identification information that identifies the item placement area A1 where the worker 12 will work.

[0031] Examples of the location identification image include figures, numbers, letters, and images of the appearance of the item W. The location identification image may have different figures, colors, blinking speeds, etc. depending on whether the number of items W placed in the item placement area A1 is one or multiple. This reduces the chance of the worker 12 making a mistake by only performing work on one item W despite receiving work instructions for multiple items W.

[0032] The display device 41 displays support images D1, which are images for supporting work corresponding to each of the multiple item placement areas A1, in display areas A3 provided corresponding to the multiple item placement areas A1. In this embodiment, one display area A3 is provided corresponding to the multiple item placement areas A1 lined up in the arrangement direction. Multiple support images D1 are displayed in this single display area A3.

[0033] FIG. 5 is a diagram showing an example of a detection area A2 detected by the detection device 42. The work support device 30 is equipped with the detection device 42. The detection device 42 detects the movement of the worker 12 relative to each of the multiple item placement areas A1. In this embodiment, the detection device 42 detects the movement of the worker 12 passing through a detection area A2 set corresponding to the item placement area A1. The movement of the worker 12 detected by the detection device 42 may be the movement of the worker's 12's arms, head, legs, tools held by the worker 12, etc. The detection area A2 may be an area formed by multiple detection lines or may be a detection surface. The shape (e.g., dimensions, arrangement, etc.) of the detection area A2 may be changed depending on the dimensions of the item W placed in the item placement area A1. In this embodiment, the detection device 42 detects a part of the body of the worker 12 passing through the detection area A2. Note that the detection device 42 may be configured to detect contact with the detection area A2 instead of passage through the detection area A2.

[0034] In this embodiment, the detection device 42 is a device that acquires three-dimensional information and detects the movement of the worker 12, but it may also be a device that detects the movement of the worker 12 by performing image processing on two-dimensional or three-dimensional images captured by an image sensor. Examples of the detection device 42 include a time-of-flight (TOF) sensor, a range sensor, an infrared sensor, a visible light sensor, an ultrasonic sensor, a sound sensor, and a contact-type displacement sensor.

[0035] As shown in Figures 4 and 5, the detection area A2 is set closer to the front side X1 than the item W placed in the corresponding item placement area A1. The detection area A2 may include the entire flexible portion 32t when viewed from the front side X1. At least a portion of the detection area A2 is set between the flexible portion 32t and the stopping portion 24 when viewed in the depth direction. At least a portion of the detection area A2 is set so as to overlap with the display area A3 when viewed in the depth direction. In this embodiment, at least a portion of the detection area A2 is set so as to be closer to the front side X1 than the flexible portion 32t when viewed in the up-down direction and so as to overlap with the flexible portion 32t when viewed in the depth direction.

[0036] At least a part of the detection area A2 is set to overlap with the flexible portion 32t when viewed from the front side X1. In this embodiment, the item placement device 20 is a shelf having multiple tiers of support portions 22 lined up in the vertical direction Z, and the detection area A2 set corresponding to the item placement area A1 set on at least the uppermost support portion 22 is set to overlap with the flexible portion 32t when viewed from the front side X1.

[0037] At least a portion of the detection area A2 is set below the flexible portion 32t on the Z2 side as viewed from the front side X1. Also, at least a portion of the detection area A2 is set above the item W or the item placement area A1 on the Z1 side as viewed from the front side X1. In this embodiment, the item placement device 20 is a shelf having multiple tiers of support units 22 arranged in the vertical direction Z, and the detection area A2 set corresponding to the item placement area A1 set on at least the lowest support unit 22 is set below the Z2 side of the flexible portion 32t as viewed from the front side X1. In this way, it is possible to easily detect the movement of the worker 12 even on a support unit 22 on the lowest tier or the like where there is a high possibility that the worker 12 will touch the item W from above Z1.

[0038] 5, in this embodiment, the work assistance device 30 is provided with a sound wave output device 43 that outputs audible sound. Examples of the sound wave output device 43 include a speaker, a chime, etc. In this embodiment, the display device 41 and the sound wave output device 43 are integrally provided in an input / output device 45.

[0039] 3, one item placement area A1 set on the support part 22 is defined as a target area A1m, and the display member 32 corresponding to the target area A1m is defined as a target display member 32m. A support image D1 for work on the item W placed in the target area A1m is displayed in the display area A3 of the target display member 32m.

[0040] The flexible portion 32t of the target display member 32m is disposed so as to extend downward Z2 from the fixed portion 32s. The fixed portion 32s of the target display member 32m is fixed to a target support member 31m, which is a support member 31 corresponding to the target area A1m.

[0041] The target support member 31m is the support portion 22 adjacent to the upper side Z1 of the target area A1m. The support portion 22 adjacent to the upper side Z1 of the target area A1m includes the stop portion 24 and the attachment portion 37 shown in FIG.

[0042] 3, in this embodiment, the target support member 31m is a support section 22 adjacent to the upper side Z1 of the target area A1m, and is a different support section 22 from the support section 22 that supports the item W in the target area A1m. The target support member 31m is a support section 22 one stage above the support section 22 that supports the item W in the target area A1m.

[0043] In this embodiment, the target area A1m, which has the support section 22 adjacent to the upper side Z1 as the target support member 31m, is set for each of the multiple support sections 22, but may be set for only one support section 22. In this embodiment, the target area A1m is an item placement area A1 set for the support section 22 of a section other than the top section. In this embodiment, the support member 31 corresponding to the item placement area A1 set for the support section 22 of the top section supports a display member 32, but does not support an item W.

[0044] The work support device 30 has a special display screen 53 on which an image different from that in the display area A3 is displayed. The image displayed on the special display screen 53 may be projected by the display device 41, which is a projection device, or may be displayed by the display device 41, which is a liquid crystal display or the like. The image displayed on the special display screen 53 includes a button image D2 for the worker 12 to give instructions to the work support device 30. Examples of instructions to the work support device 30 include a request to replenish the item W, a request for help, a call for a manager, an emergency stop, and redisplaying the support image D1.

[0045] The special display surface 53 is arranged on the upper side Z1 of the display area A3 of the display member 32 corresponding to the item placement area A1 set on the top support section 22. In this embodiment, the support member 31 corresponding to the item placement area A1 set on the top support section 22 supports the special display member 52 equipped with the special display surface 53. Examples of the special display member 52 include a plate supported on the support member 31 or support section 22, part of a pillar of a shelf or building, part of a beam of a shelf or building, part of a shelf frame, a display device supported on a shelf or building, etc.

[0046] The special display screen 53 is disposed at an end of the item placement device 20 in the width direction Y. The special display screen 53 is disposed at an end of the upper side Z1 of the item placement device 20. The special display screen 53 is disposed adjacent to the display area A3. In this embodiment, an image indicating whether or not a location-specific image is displayed on the special display screen 53 disposed at an end of one side Y1 in the width direction Y is displayed. In this manner, the presence of a location-specific image on the other side Y2 in the width direction Y can be recognized by visually checking the one side Y1 in the width direction Y, thereby reducing the risk of overlooking the location-specific image and reducing the time spent searching for it, thereby improving work efficiency. In the illustrated example, the special display screen 53 is disposed at an end of the item placement device 20 on the upstream side in the conveying direction of the conveying device 28. In the example shown in FIG. 3, the special display screen 53 faces the downstream side in the conveying direction of the conveying device 28.

[0047] Although not shown, the work equipment 10 may be equipped with multiple item placement devices 20, or may be equipped with only one item placement device 20. The multiple item placement devices 20 are equipped on the work equipment 10, for example, so that they are lined up in the depth direction X or width direction Y. The multiple item placement devices 20 are arranged, for example, so that one item placement device 20 corresponds to one display device 41 or one detection device 42. In this embodiment, one display device 41 displays one or more support images D1 in each of multiple display areas A3 lined up in the vertical direction Z. In the example shown, one display area A3 is arranged from one end to the other end in the arrangement direction of one item placement device 20.

[0048] Returning to FIG. 1 , the work assistance device 30 includes a control system 70. The control system 70 controls the display device 41, the detection device 42, and the sonic wave output device 43. The control system 70 includes a control device having an arithmetic processing device such as a CPU (Central Processing Unit) and a main storage device accessible by the arithmetic processing device, such as a RAM (Random Access Memory) or a ROM (Read Only Memory). Each function of the control device is realized by cooperation between hardware included in the control device and a program executed on the hardware, such as the arithmetic processing device. In this embodiment, the control device (specifically, the arithmetic processing device included in the control device) functions as a "computer." The control device may be a host control device installed in a control facility (not shown). For example, when the control device includes multiple pieces of hardware separated so as to be able to communicate with each other, some of the hardware may be included in the input / output device 45, and the remaining hardware may be installed in a control facility (not shown). For example, the control device may be a tablet PC, or part of the control device may be installed in the tablet PC.

[0049] The control system 70 is configured to be able to execute a "work support mode" in which work support is provided to the worker 12. In the work support mode, the support image D1 includes instruction content information indicating the content of work instructions given to the worker 12. Examples of instruction content information include the name of the item W, an image of the item W, a product identification code such as a GTIN (Global Trade Item Number), letters (numbers) indicating the work quantity such as the amount of item W to be taken out or the amount of item W to be put in, and an identification code indicating the type of item.

[0050] The display device 41 displays at least a portion of the portion of the support image D1 that represents the instruction content information on the fixed portion 32s. In this embodiment, the display device 41 displays 80% or more or 90% or more of the portion of the support image D1 that represents the instruction content information on the fixed portion 32s. In this embodiment, the display device 41 displays the portion of the support image D1 that represents the instruction content information on the fixed portion 32s and the flexible portion 32t.

[0051] In the work support mode, the control system 70 displays, on the display device 41, a support image D1 corresponding to the item placement area A1 in which the item W to be worked on by the worker 12 is placed. Multiple support images D1 corresponding to the item placement area A1 in which the item W to be worked on is placed may be displayed simultaneously, or only one may be displayed.

[0052] In the work assistance mode, the control system 70 identifies the item placement area A1 of the item W on which the worker 12 has worked based on the movement of the worker 12 passing through the detection area A2 set corresponding to the item placement area A1.

[0053] In the work support mode, if the control system 70 determines that the item placement area A1 for the item W on which the worker 12 has performed work is the item placement area A1 for the item W to be worked on by the worker 12, the control system 70 displays a correct image on the display device 41 in the display area A3 where the support image D1 is displayed. Examples of the correct image include an image in a color (blue, green, etc.) different from the support image D1, a shape (circle, square, etc.) indicating the correct answer, or text indicating the correct answer. Examples of an image in which the display mode of the support image D1 has been changed include an image in which the color of the support image D1 has been changed, an image in which a shape (circle, square, etc.) has been superimposed on the support image D1, or an image in which text indicating the correct answer has been superimposed.

[0054] In the work support mode, when the control system 70 determines that the item placement area A1 for the item W on which the worker 12 has worked is an item placement area A1 other than the item W that is the target of the work by the worker 12, the control system 70 displays an image different from the correct image in multiple display areas A3 (for example, all display areas A3 of the item placement device 20) on the display device 41. Examples of images different from the correct image include a graphic indicating an error, text indicating an error, an image in a color (red, yellow, etc.) different from the correct image, a flashing image, etc.

[0055] In the work support mode, when the control system 70 determines that the item placement area A1 of the item W on which the worker 12 has worked is an item placement area A1 other than the item W that is the target of the work by the worker 12, the control system 70 outputs an audible sound from the sound wave output device 43. The control system 70 may also output an audible sound from the sound wave output device 43 when it determines that the item placement area A1 of the item W on which the worker 12 has worked is the item placement area A1 of the item W that is the target of the work by the worker 12. In these cases, the control system 70 outputs different audible sounds from the sound wave output device 43.

[0056] 6 is a diagram showing an example of setting an array direction detection range M2. The display range of the array direction of the support image D1 corresponding to each of the multiple item placement areas A1 is defined as the array direction display range M1. Furthermore, the detection range of the array direction of the detection area A2 corresponding to each of the multiple item placement areas A1 is defined as the array direction detection range M2. The dimensions of the array direction detection range M2 are the dimensions of the detection area A2 in the array direction.

[0057] The control system 70 sets the arrangement direction display range M1 according to the range of the arrangement direction of the corresponding item placement area A1. In this embodiment, the control system 70 sets the arrangement direction display range M1 so that it overlaps at least a portion of the range of the arrangement direction of the corresponding item placement area A1 in the arrangement direction or in a direction intersecting the arrangement direction (for example, the vertical direction Z). In this embodiment, the arrangement direction display range M1 is set to match the range of the arrangement direction of the corresponding item placement area A1, but it may be set wider or narrower than the range of the arrangement direction of the corresponding item placement area A1.

[0058] The control system 70 sets the range of the image display range C1 in a direction intersecting the arrangement direction (e.g., the vertical Z direction) according to the range of the corresponding item placement area A1 in a direction intersecting the arrangement direction (e.g., the vertical Z direction). In this embodiment, the control system 70 sets the range of the image display range C1 in a direction intersecting the arrangement direction (e.g., the vertical Z direction) so that it at least partially overlaps with the range of the corresponding item placement area A1 in a direction intersecting the arrangement direction (e.g., the vertical Z direction) or in the arrangement direction. In this embodiment, the range of the image display range C1 in a direction intersecting the arrangement direction (e.g., the vertical Z direction) is set to match the range of the corresponding item placement area A1 in a direction intersecting the arrangement direction (e.g., the vertical Z direction), but may be set wider or narrower than the range of the corresponding item placement area A1 in a direction intersecting the arrangement direction (e.g., the vertical Z direction).

[0059] In this embodiment, the control system 70 sets the array direction detection range M2 further inward in the array direction than the array direction display range M1 corresponding to the same item placement area A1. In this embodiment, the control system 70 sets the range of the image display range C1 in a direction intersecting the array direction (for example, the vertical Z direction) further inward in the direction intersecting the array direction (for example, the vertical Z direction) than the detection area A2 corresponding to the same item placement area A1. In this embodiment, the control system 70 matches the center position of the image display range C1 and the center position of the detection area A2 in the direction intersecting the array direction (for example, the vertical Z direction), but they may be set to be different.

[0060] Here, the set value of the ratio of the dimensions of the array direction detection range M2 to the dimensions of the array direction display range M1 is set as a ratio set value H1. The control system 70 sets the array direction detection range M2 based on the array direction display range M1 and the ratio set value H1.

[0061] 7 is a diagram showing another example of setting the array direction detection range M2. Here, the set value of the difference between the dimensions of the array direction detection range M2 and the dimensions of the array direction display range M1 is set as a difference set value H2. The control system 70 sets the array direction detection range M2 based on the array direction display range M1 and the difference set value H2.

[0062] Here, an instruction to change the ratio setting value H1 or the difference setting value H2 is referred to as a setting value change instruction E2. When the control system 70 receives the setting value change instruction E2, it changes the arrangement direction detection range M2 corresponding to the item placement area A1 in accordance with the setting value change instruction E2. In this embodiment, when the control system 70 receives the setting value change instruction E2, it changes the arrangement direction detection range M2 corresponding to each of the multiple item placement areas A1 in accordance with the setting value change instruction E2. In this embodiment, the control system 70 matches the center position of the arrangement direction display range M1 with the center position of the arrangement direction detection range M2, but they may be set to be different.

[0063] The control system 70 can set an arrangement direction detection range M2 corresponding to each of the multiple item placement areas A1 for each of the multiple item placement areas A1. The control system 70 can set a detection range in the up-down direction Z of the detection area A2 corresponding to each of the multiple item placement areas A1 for each of the multiple item placement areas A1.

[0064] Here, a plurality of detection areas A2 corresponding to a plurality of item placement areas A1 set on each of the plurality of support sections 22 are defined as a detection area group. The control system 70 can set, for each detection area group, a detection range in the up-down direction Z of the detection areas A2 belonging to the detection area group corresponding to each of the plurality of support sections 22. In this embodiment, the detection area group is a plurality of detection areas A2 aligned in the arrangement direction on each of the support sections 22. A plurality of detection area groups may be set so as to be aligned in the arrangement direction on each of the plurality of support sections 22, or one detection area group may be set on each of the plurality of support sections 22.

[0065] The control system 70 can set a ratio setting value H1 or a difference setting value H2 for each detection area group, and when it receives a setting value change instruction E2, it changes the array direction detection range M2 of all detection areas A2 belonging to the detection area group in accordance with the setting value change instruction E2.

[0066] The control system 70 can set a differential setting value H2 for each detection area group, and when a setting value change instruction E2 is received, the control system 70 changes the array direction detection range M2 of all detection areas A2 belonging to the detection area group in accordance with the setting value change instruction E2.

[0067] Here, an instruction to change the position and dimensions of the arrangement direction of the arrangement direction display range M1 corresponding to each of the multiple item placement areas A1 is referred to as a display range change instruction E1. When the control system 70 receives the display range change instruction E1, it changes the arrangement direction display range M1 of the support image D1 in accordance with the display range change instruction E1, and also changes the arrangement direction detection range M2 of the detection area A2 corresponding to the same item placement area A1 in accordance with the change in the arrangement direction display range M1. In this embodiment, the control system 70 aligns the center position of the arrangement direction display range M1 with the center position of the array direction detection range M2, but they may also be set to be different.

[0068] In this embodiment, the setting of the array direction display range M1 is set using the range setting mode described below according to the range of the array direction of the corresponding item placement area A1, but it may also be set automatically so that it is adjacent to or includes at least a portion of the corresponding item placement area A1, or it may be set manually so that it is adjacent to or includes at least a portion of the corresponding item placement area A1.

[0069] The range in the display area A3 where the support image D1 is displayed is referred to as the image display range C1. The range sandwiched between two adjacent image display ranges C1 in the array direction is referred to as the boundary range C2. In the illustrated example, the image display range C1 and the support image D1 have the same area, but the area of ​​the support image D1 may be smaller than the area of ​​the image display range C1. The array direction display range M1 described above is the range in the array direction of the image display range C1. The dimensions of the array direction display range M1 are the dimensions of the image display range C1 in the array direction.

[0070] In this embodiment, boundary range C2 is a range indicated by an area specified by a position and width in the array direction. In the illustrated example, boundary range C2 is set at the edge of display area A3, but boundary range C2 does not have to be set at the edge of display area A3. Examples of boundary range C2 include a range indicated by an ellipse, a range indicated by multiple lines extending in the vertical direction Z or the array direction, and a range indicated as a space between two lines extending in the vertical direction Z or the array direction.

[0071] In this embodiment, the control system 70 is configured to be able to execute a "range setting mode" in which an image display range C1 is set. In the range setting mode, the control system 70 displays a boundary range C2 in the display area A3 using the display device 41. When the control system 70 receives an instruction E3 to change the boundary range C2 in the range setting mode, the control system 70 changes the boundary range C2 displayed in the display area A3 in accordance with the instruction E3. In this embodiment, the display range change instruction E1 is derived from the instruction E3 to change the boundary range C2.

[0072] A plurality of display areas A3 are set corresponding to the plurality of support parts 22 aligned in the vertical direction Z. In this embodiment, one detection area group is set for each of the plurality of display areas A3, but a plurality of detection area groups may be set to be aligned in the arrangement direction in each of the plurality of display areas A3. The control system 70 is configured to be able to receive a change instruction E3 for each boundary range C2 in each of the plurality of display areas A3.

[0073] The vertical Z dimension of boundary range C2 is set as a common value for each display area A3 that includes boundary range C2. In this embodiment, the vertical Z dimension of image display range C1 is set as a common value for each display area A3 that includes image display range C1. In this embodiment, the vertical Z dimension of boundary range C2 and the vertical Z dimension of image display range C1 are a common value, but they may be different values.

[0074] In this embodiment, one display area A3 is set for one support section 22 among the multiple support sections 22, and the vertical Z dimension of the boundary range C2 included in one display area A3 is set to a common value. In this embodiment, the vertical Z dimension of the boundary range C2 in the multiple display areas A3 can be set to a different value for each display area A3. In this embodiment, the vertical Z dimension of the boundary range C2 in the multiple display areas A3 can be set to a common value.

[0075] The modification instruction E3 includes an instruction E31 to change the position of the boundary area C2 in the arrangement direction (for example, the width direction Y). The modification instruction E3 includes an instruction E32 to change the dimension of the boundary area C2 in the arrangement direction. The modification instruction E3 may or may not include an instruction to change the position and dimension of the boundary area C2 in a direction perpendicular to the arrangement direction (for example, the vertical direction Z). The instruction E32 to change the dimension of the boundary area C2 in the arrangement direction may be made by moving the position of the edge of the boundary area C2, or by inputting a value.

[0076] In this embodiment, in the range setting mode, the position and dimensions of the boundary range C2 in a direction perpendicular to the arrangement direction (for example, the vertical direction Z) can be changed, but they may not be changed. In this embodiment, the dimension of the boundary range C2 in a direction perpendicular to the arrangement direction is set to a value equal to the dimension of the display area A3 in that direction, but may be set to a value smaller than the dimension of the display area A3 in that direction. An instruction to change the dimension of the boundary range C2 in the direction perpendicular to the arrangement direction may be given by moving the position of the edge of the boundary range C2, or by inputting a value.

[0077] The control system 70 is configured to be able to receive, as the change instruction E3, an instruction E32 to change a dimension in an arrangement direction (e.g., the width direction Y) common to the boundary ranges C2 of each display area A3. The control system 70 is configured to be able to receive, as the change instruction E3, an instruction E32 to change a dimension in a direction (e.g., the up-down direction Z) perpendicular to the arrangement direction common to the boundary ranges C2 of each display area A3. When the control system 70 receives an instruction E32 to change a dimension in the arrangement direction or the direction perpendicular to the arrangement direction common to the boundary ranges C2 of each display area A3, the control system 70 changes the boundary range C2 for each display area A3 in accordance with the instruction E32.

[0078] FIG. 8 is a diagram showing an example of an input receiving terminal 71 provided in the work equipment 10. The control system 70 is provided with an input receiving terminal 71 that receives input from a manager or worker 12. Examples of a manager include a person who manages the item placement device 20, a person who manages the work support device 30, a person who manages the workers 12, and a person who maintains the work equipment 10. Note that a manager may also serve as a worker 12. Examples of the input receiving terminal 71 include a tablet computer, a desktop computer, a touch panel, and a voice input device. In this embodiment, the input receiving terminal 71 is a portable device that can be carried around and used.

[0079] The input receiving terminal 71 includes a display unit 71a that displays an image. The input receiving terminal 71 includes an input unit 71b that receives operation input for the image displayed on the display unit 71a. Examples of the input unit 71b include a touch panel, a keyboard, a mouse, and a voice input device for changing the image displayed on the display unit 71a.

[0080] In the range setting mode, the control system 70 displays a layout diagram Dc1 on the display unit 71a, which shows the layout of the image display area C1 and boundary area C2. In this embodiment, the number and positional relationship of the image display areas C1 and boundary area C2 displayed in the layout diagram Dc1 are the same as the number and positional relationship of the image display areas C1 and boundary area C2 in the corresponding display area A3. The ratio of the dimensions in the arrangement direction of the image display areas C1 and boundary area C2 displayed in the layout diagram Dc1 may be the same as or different from the ratio of the dimensions in the arrangement direction of the image display areas C1 and boundary area C2 in the corresponding display area A3.

[0081] In the range setting mode, the control system 70 displays on the display unit 71a an object display image Dc2 indicating the boundary range C2 to be set on the layout plan Dc1. In the range setting mode, the control system 70 displays on the display unit 71a an operation image Dc3 that is an image for accepting an operation input for a change instruction E3 from the input unit 71b.

[0082] 9 is a diagram showing an example of a management terminal 72 provided in the work equipment 10. The control system 70 is provided with a management terminal 72 used by a manager. Examples of the management terminal 72 include monitors and displays using LCD, organic EL, LED, etc., tablet computers, desktop computers, touch panels, voice input devices, etc. In this embodiment, the management terminal 72 is a portable device that can be carried around and used.

[0083] The management terminal 72 is equipped with a display unit 72a that displays images. The input receiving terminal 71 is equipped with a display unit 71a that displays images. The management terminal 72 is equipped with an input unit 72b that receives operation input for the image displayed on the display unit 72a. Examples of the input unit 72b include a touch panel, a keyboard, a mouse, and a voice input device for changing the image displayed on the display unit 72a.

[0084] In the range setting mode, the control system 70 displays on the display unit 72a a layout diagram Dc1 showing the layout of the image display range C1 and the boundary range C2, and also displays a detection status image Dc4 showing the detection status of the detection device 42, superimposed on the layout diagram Dc1. Examples of the detection status include the layout of the detection area A2, the position and dimensions of the detection area A2, the positional relationship between the image display range C1 and the detection area A2, and whether or not the operator 12 has contacted or passed through the detection area A2. In this embodiment, the management terminal 72 is configured to be able to display, on the display unit 72a, a detection status image Dc4 showing whether or not the operator 12 has contacted or passed through the detection area A2, and a detection area diagram Dc5 showing the position and dimensions of the detection area A2, superimposed on the layout diagram Dc1, in the range setting mode.

[0085] In this embodiment, when the worker 12 touches or passes through the detection area A2, the control system 70 changes the display of the detection area A2 or the image display range C1 on the display unit 72a. In this embodiment, when the control system 70 no longer detects the worker 12 touching or passing through the detection area A2, the control system 70 returns the display of the detection area A2 or the image display range C1 to the display before the change.

[0086] Examples of changes to the display of the detection area A2 or image display range C1 include changing the color of the detection area A2 or image display range C1, changing the lighting time, changing the blinking time, adding text or graphics, changing the outer frame, etc.

[0087] The position of the detection area A2 in a direction perpendicular to the arrangement direction (for example, the vertical direction Z) may be set according to the position of the image display range C1 or the boundary range C2, or may be set according to input from the input unit 71b of the input receiving terminal 71 or the input unit 72b of the management terminal 72. The dimension of the detection area A2 in the vertical direction Z may be set according to the dimension of the image display range C1 or the boundary range C2, or may be set according to input from the input unit 71b of the input receiving terminal 71 or the input unit 72b of the management terminal 72.

[0088] Examples of setting the position of the detection area A2 in a direction perpendicular to the array direction (for example, the vertical direction Z) include a configuration in which the detection area A2 is automatically set so that it is inside the image display range C1 when viewed in the depth direction, a configuration in which the detection area A2 is automatically set so that it overlaps with at least a portion of the image display range C1 when viewed in the depth direction, a configuration in which the detection area A2 is automatically set so that it is adjacent to the image display range C1, and a configuration in which the detection area A2 is automatically set so that it is separated from the image display range C1 by a certain range.

[0089] In this embodiment, the input receiving terminal 71 and the management terminal 72 are the same terminal, but the input receiving terminal 71 and the management terminal 72 may be different terminals. The input receiving terminal 71 or the management terminal 72 does not have to be a portable device. A terminal that displays the special display screen 53 arranged at the end on one side Y1 in the width direction Y may also serve as both the input receiving terminal 71 and the management terminal 72.

[0090] In this embodiment, in the range setting mode, the control system 70 displays an image display range C1 in the display area A3 of the display member 32 using the display device 41. In this embodiment, in the range setting mode, the control system 70 displays a boundary range C2 in the display area A3 using the display device 41.

[0091] In the range setting mode, the control system 70 executes an automatic setting process when it receives input of setting information indicating the number of image display ranges C1 or boundary ranges C2. In this embodiment, in the range setting mode, the control system 70 executes an automatic setting process when it receives input of setting information indicating the number of image display ranges C1 or boundary ranges C2 and the dimensions of the image display ranges C1 in the arrangement direction. In the range setting mode, the control system 70 executes an automatic setting process when it receives input of setting information indicating the number of image display ranges C1 and the dimensions of the image display ranges C1 in the arrangement direction.

[0092] Note that the control system 70 may be configured to execute automatic setting processing when it receives input of setting information in the range setting mode, which is information indicating the number of image display ranges C1 or boundary ranges C2 and the dimensions of the boundary ranges C2 in the arrangement direction. The dimensions of the boundary ranges C2 in the arrangement direction do not include 0, but may include it.

[0093] In the automatic setting process, the control system 70 automatically sets the position of the boundary range C2 in the arrangement direction based on the setting information. In the automatic setting process, the control system 70 automatically sets the dimensions of the boundary range C2 in the arrangement direction based on the setting information. In the range setting mode, the control system 70 displays the boundary range C2 in the display area A3 according to the setting made by the automatic setting process as the initial setting before accepting the change instruction E3.

[0094] In this embodiment, the size of the image display range C1 in the arrangement direction in the initial setting is determined by equally dividing it by the number of image display ranges C1. Note that the number of image display ranges C1 may be derived from the number of boundary ranges C2. In this embodiment, the position and size of the boundary range C2 in a direction perpendicular to the arrangement direction is the size of the display area A3 in that direction or the spacing between adjacent support parts 22.

[0095] The control system 70 may be configured to be able to execute modes other than the work support mode and the range setting mode. Although not shown, in this embodiment, the control system 70 is configured to be able to execute an "information display mode" that displays the number, quantity, or type of items W placed in the item placement area A1. In this embodiment, the control system 70 displays the number, quantity, and type of items W placed in each of the multiple item placement areas A1 in the information display mode. In the information display mode, the number, quantity, or type of items W placed in all item placement areas A1 set in the item placement device 20 may be displayed, or the number, quantity, or type of items W placed in some of the item placement areas A1 set in the item placement device 20 may be displayed.

[0096] The technical features of the work equipment 10 according to the present disclosure can also be applied to a work assistance method and a work assistance program.

[0097] Other Embodiments Next, other embodiments of the working equipment 10 will be described.

[0098] (1) In the above embodiment, the depth direction X is horizontal. However, the present invention is not limited to such an example. For example, the depth direction X may be the same direction as the up-down direction Z, or the depth direction X may be inclined relative to the horizontal. For example, the front side X1 of the item placement device 20 may be the top surface of the item placement device 20, or the front side of the item placement device 20 may be inclined upward Z1 or downward Z2 relative to the horizontal.

[0099] (2) In the above embodiment, an example has been described in which the control system 70 is capable of setting the array direction detection range M2 based on the ratio set value H1 or the difference set value H2 and the array direction display range M1. However, the present invention is not limited to such an example. For example, the control system 70 may be configured to set the array direction detection range M2 based on the ratio set value H1, the difference set value H2, and the array direction display range M1. Furthermore, for example, the control system 70 may be configured not to be able to set the array direction detection range M2 based on the difference set value H2.

[0100] (3) In the above embodiment, the arrangement direction detection range M2 is changed when a display range change instruction E1, which is an instruction to change the position and dimensions of the arrangement direction of the arrangement direction display range M1, is received. However, the present invention is not limited to such an example. For example, the arrangement direction detection range M2 may not be changed when the display range change instruction E1 is received, but multiple arrangement direction detection ranges M2 may be changed manually. For example, the arrangement direction detection range M2 may be changed when an instruction to change the position or dimensions of the arrangement direction of the arrangement direction display range M1 is received.

[0101] (4) In the above embodiment, an example has been described in which the control system 70 can set the detection range in the vertical direction Z of the detection areas A2 belonging to each detection area group for each detection area group. However, without being limited to such an example, for example, the control system 70 may not be able to set the detection range in the vertical direction Z of the detection areas A2 belonging to each detection area group for each detection area group. For example, the control system 70 may be able to set the detection range in the arrangement direction or the vertical direction Z of any multiple detection areas A2 for each of the multiple detection areas A2.

[0102] (5) In the above embodiment, the boundary range C2 is an area defined by the position and width in the arrangement direction. However, the present invention is not limited to such an example. For example, the boundary range C2 may be a blank area. Furthermore, for example, the boundary range C2 may be a line extending in the vertical direction Z as shown in FIG. 10. Furthermore, for example, the target display image Dc2 may be displayed using a thick line indicating the boundary range C2 as shown in FIG. 11.

[0103] (6) In the above embodiment, the change instruction E3 includes an instruction E31 to change the position of the boundary range C2 in the arrangement direction and an instruction E32 to change the dimension of the boundary range C2 in the arrangement direction. However, the change instruction E3 is not limited to this example. For example, the change instruction E3 may include only one of the instructions E31 and E32.

[0104] (7) In the above embodiment, a configuration has been described in which a plurality of display areas A3 are set corresponding to the plurality of stages of support units 22 arranged in the vertical direction Z, the dimensions of the image display range C1 and the boundary range C2 in the vertical direction Z are set as common values ​​for each display area A3 included therein, and the control system 70 can accept a change instruction E3 for each boundary range C2 in each of the plurality of display areas A3. However, the present invention is not limited to such an example. For example, only one display area A3 may be set corresponding to the plurality of stages of support units 22 arranged in the vertical direction Z. For example, the dimensions of the plurality of image display ranges C1 or the plurality of boundary ranges C2 included in one display area A3 in the vertical direction Z may be set to different values. For example, the control system 70 may not accept a change instruction E3 for each boundary range C2 in each of the plurality of display areas A3.

[0105] (8) In the above embodiment, the change instruction E3 includes an instruction E31 to change the position of the boundary range C2 in the arrangement direction and an instruction E32 to change the dimension of the boundary range C2 in the arrangement direction. However, the change instruction E3 is not limited to this example. For example, the change instruction E3 may include either the instruction E31 to change the position of the boundary range C2 in the arrangement direction or the instruction E32 to change the dimension of the boundary range C2 in the arrangement direction.

[0106] (9) In the above embodiment, the control system 70 is configured to be able to accept, as the change instruction E3, an instruction E32 to change a dimension in the arrangement direction common to the boundary range C2 of each display area A3. However, without being limited to such an example, the control system 70 may be configured to be unable to accept, as the change instruction E3, an instruction E32 to change a dimension in the arrangement direction common to the boundary range C2 of each display area A3. For example, the control system 70 may be configured to be able to accept, as the change instruction E3, an instruction E32 to change a dimension in the arrangement direction common to multiple boundary ranges C2 of one display area A3.

[0107] (10) In the above embodiment, an example has been described in which the control system 70, when in the range setting mode, receives input of setting information indicating the number of image display ranges C1 or boundary ranges C2 and the dimensions of the display ranges in the arrangement direction, executes the automatic setting process based on the setting information. However, without being limited to such an example, for example, the control system 70 may be configured to, when in the range setting mode, receive input of setting information indicating the number of image display ranges C1 or boundary ranges C2, execute the automatic setting process based on the setting information.

[0108] (11) In the above embodiment, an example has been described in which the control system 70 executes an automatic setting process to automatically set the position and dimensions of the boundary range C2 in the arrangement direction based on the setting information. However, the present invention is not limited to such an example. For example, the control system 70 may execute an automatic setting process to automatically set only the position of the boundary range C2 in the arrangement direction based on the setting information. For example, the control system 70 may execute an automatic setting process to automatically set only the dimensions of the boundary range C2 in the arrangement direction based on the setting information.

[0109] (12) In the above embodiment, the control system 70, in the range setting mode, displays the boundary range C2 in the display area A3 according to the settings made by the automatic setting process as the initial setting before accepting the change instruction E3. However, the present invention is not limited to such an example. For example, the control system 70 may display the boundary range C2 in the display area A3 according to settings that are different from the automatic setting process, such as settings made in advance by an administrator, as the initial setting before accepting the change instruction E3.

[0110] (13) In the above embodiment, the input receiving terminal 71 includes a display unit 71a and an input unit 71b, and the control system 70 displays the layout plan Dc1, the target display image Dc2, and the operation image Dc3 on the display unit 71a in the range setting mode. However, the present invention is not limited to such an example. For example, the layout plan Dc1 or the target display image Dc2 may not be displayed on the display unit 71a. For example, the input receiving terminal 71 may include only the input unit 71b, and the control system 70 may display the layout plan Dc1 and the target display image Dc2 in the display area A3 of the display member 32 in the range setting mode.

[0125] (28) The configurations disclosed in the above-described embodiments may be combined with configurations disclosed in other embodiments as long as no contradiction arises. 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.

[0126] [Summary of the above embodiment] The work equipment according to the present disclosure will be described below.

[0127] In one aspect, the work equipment comprises an item placement device having a plurality of item placement areas each having an item placed therein, and a work support device that provides work support to a worker who works on items placed in the plurality of item placement areas, wherein the plurality of item placement areas are set to be aligned along a predetermined arrangement direction, and the work support device comprises a display device that displays support images for the work corresponding to each of the plurality of item placement areas in display areas provided corresponding to the plurality of item placement areas, a detection device that detects the movement of a worker passing through detection areas set corresponding to each of the plurality of item placement areas, and a control system, wherein the display range of the arrangement direction of the support images corresponding to each of the plurality of item placement areas is set as an arrangement direction display range, and the detection range of the arrangement direction of the detection areas corresponding to each of the plurality of item placement areas is set as an arrangement direction detection range, and the control system sets the arrangement direction display range according to the range of the arrangement direction of the corresponding item placement area, and sets the arrangement direction detection range to be more inward in the arrangement direction than the arrangement direction display range corresponding to the same item placement area.

[0128] According to this configuration, support images corresponding to each of a plurality of item placement areas can be displayed in a range in the arrangement direction corresponding to the corresponding item placement area, and detection areas corresponding to two adjacent item placement areas in the arrangement direction can be spaced apart in the arrangement direction. Therefore, when a worker works on an item placed in one item placement area, the possibility of the worker's movement being erroneously detected in a detection area set corresponding to another adjacent item placement area in the arrangement direction can be reduced. This makes it easier to improve the accuracy of detecting the movement of a worker working on an item placed in an item placement area, and, for example, makes it easier for the detection device to detect whether the worker has worked on the correct item placement area. This makes it easier to improve work efficiency.

[0129] In one aspect, when a ratio setting value is set as the ratio of the dimensions of the array direction detection range to the dimensions of the array direction display range, the control system sets the array direction detection range based on the array direction display range and the ratio setting value, and when a setting value change instruction that is an instruction to change the ratio setting value is received, the control system changes the array direction detection range corresponding to each of the multiple item placement areas in accordance with the setting value change instruction.

[0130] This configuration allows the array direction detection range of the detection area to be set in accordance with the array direction display range of each of the support images, thereby simplifying the task of setting the detection area compared to when the array direction detection ranges of the multiple detection areas are set individually.

[0131] In one aspect, when the control system receives a display range change instruction that is an instruction to change the arrangement direction position and arrangement direction dimension of the arrangement direction display range corresponding to each of the multiple item placement areas, the control system changes the arrangement direction display range of the support image in accordance with the display range change instruction, and changes the arrangement direction detection range of the detection area corresponding to the same item placement area in accordance with the change in the arrangement direction display range.

[0132] According to this configuration, the array direction detection range of the detection area corresponding to each of the multiple item placement areas can be changed in accordance with a change in the array direction display range of the support image corresponding to each of the multiple item placement areas, thereby simplifying the work of setting the detection area compared to when the array direction display range of the support image and the array direction detection range of the detection area are changed separately.

[0133] In one embodiment, the item placement device is a shelf having a plurality of support parts lined up in the vertical direction, and a plurality of the item placement areas are set on each of the plurality of support parts so that they are lined up along the horizontal arrangement direction, and the plurality of detection areas corresponding to the plurality of item placement areas set on each of the plurality of support parts are set as detection area groups, and the control system is able to set the vertical detection range of the detection areas belonging to the detection area groups corresponding to each of the plurality of support parts for each of the detection area groups.

[0134] With this configuration, the vertical detection range of the detection area of ​​the detection device can be set for each stage of the support section. Therefore, it is possible to appropriately set the detection range of the detection area to match the worker's movements, which differ for each stage of the support section. Therefore, with this configuration, it is easy to improve the accuracy of the detection device in detecting the worker's movements.

[0135] It is sufficient for the work equipment according to the present disclosure to achieve at least one of the above-described effects. [Explanation of symbols]
