[0003] [Patent Document 1] Japanese Patent Publication No. 2022-82213 Summary of the Invention [Problem to be solved by the invention]

[0004] In order to properly ensure the safety of workers who use the scaffolding, a scaffolding that is detachable from a pair of storage shelves is required to be highly stable when attached to the pair of storage shelves. In this regard, paragraph 0042 of Patent Document 1 describes providing anti-slip rubber blocks on the scaffolding (called steps in Patent Document 1), but if a force acting on the scaffolding exceeds the frictional force of the rubber blocks, the scaffolding may move. Therefore, the technology described in Patent Document 1 leaves room for improvement in terms of scaffolding stability.

[0005] Therefore, it is desirable to realize an article storage facility that can easily increase the stability of the scaffolding when attached to a pair of storage shelves. [Means for solving the problem]

[0006] In accordance with the present disclosure 1st The article storage facility is an article storage facility comprising a pair of storage shelves arranged to face each other, and scaffolding configured to be detachable from the pair of storage shelves, wherein the direction in which the pair of storage shelves face each other is defined as an X direction, a direction perpendicular to the X direction when viewed in a vertical direction is defined as a Y direction, one side in the Y direction is defined as a Y direction first side, and the other side in the Y direction is defined as a Y direction second side, the pair of storage shelves are arranged to be spaced apart in the X direction, each of the pair of storage shelves is provided with a plurality of alignment members aligned in the Y direction, and the scaffolding is configured to be detachable from the pair of storage shelves in the X direction. a locking structure that is locked to each of the pair of storage shelves in a state in which the scaffold is arranged so as to bridge between the pair of storage shelves in the Y direction, and the locking structure includes a Y-direction regulating structure that regulates movement of the scaffold in the Y direction, and the Y-direction regulating structure includes a first opposing portion that faces a first array member that is one of the array members in each of the pair of storage shelves from a first side in the Y direction, and a second opposing portion that faces the first array member in each of the pair of storage shelves or a second array member that is another array member other than the first array member from a second side in the Y direction. Each of the pair of storage shelves includes a plurality of support columns arranged in the Y direction and a horizontal member connecting the support columns adjacent to each other in the Y direction, and the scaffolding is configured to be supported from below by the horizontal member of each of the pair of storage shelves in a state in which the scaffolding is arranged to bridge between the pair of storage shelves in the X direction. .

[0007] According to this configuration, when the scaffolding is arranged to span the X-direction between a pair of storage shelves, movement of the scaffolding toward the first side in the Y direction is restricted by the second opposing portion that faces the alignment member from the second side in the Y direction, and movement of the scaffolding toward the second side in the Y direction is restricted by the first opposing portion that faces the alignment member from the first side in the Y direction. In this way, according to this configuration, movement of the scaffolding toward both sides in the Y direction when attached to a pair of storage shelves can be restricted by the contact between the members rather than by friction between the members. Therefore, it is easy to increase the stability of the scaffolding when attached to a pair of storage shelves.

DETAILED DESCRIPTION OF THE INVENTION

[0014] [First embodiment] A first embodiment of an item storage facility will be described with reference to the drawings (FIGS. 1 to 9). As shown in FIG. 1, the item storage facility 100 includes a pair of storage shelves 1 arranged to face each other. Here, the direction in which the pair of storage shelves 1 face each other is defined as the X direction, and the direction perpendicular to the X direction when viewed from the up-down direction Z is defined as the Y direction. The up-down direction Z is a vertical direction, and the X and Y directions are horizontal directions perpendicular to each other. One side in the X direction is defined as the X-direction first side X1, the other side in the X direction is defined as the X-direction second side X2, one side in the Y direction is defined as the Y-direction first side Y1, and the other side in the Y direction is defined as the Y-direction second side Y2. The pair of storage shelves 1 are arranged spaced apart in the X direction. A scaffolding 3, which will be described later, is arranged to bridge the X-direction gap between the pair of storage shelves 1.

[0015] The storage shelf 1 is equipped with a shelf section 10 that supports an item A. The item A is stored on the storage shelf 1 while being supported by the shelf section 10. The item A is, for example, a container (such as a container or cardboard box) that stores goods (such as merchandise). A plurality of items A are supported on the shelf section 10 and lined up in the Y direction. A configuration in which a plurality of items A are supported on the shelf section 10 and lined up in the Y direction at a plurality of positions in the X direction (i.e., a plurality of positions in the depth direction) can also be adopted.

[0016] As shown in Fig. 1, in this embodiment, each of a pair of storage shelves 1 has multiple shelf sections 10 arranged in the vertical direction Z. Fig. 1 shows five shelf sections 10 arranged in the vertical direction Z. The shelf sections 10 on the same level in each of the pair of storage shelves 1 are arranged at the same position in the vertical direction Z.

[0017] Each of the pair of storage shelves 1 includes a plurality of alignment members 11 aligned in the Y direction. The plurality of alignment members 11 are aligned so that gaps are formed between adjacent alignment members 11 in the Y direction. The spacing between the plurality of alignment members 11 in the Y direction may vary depending on the location, but in this embodiment, the plurality of alignment members 11 are aligned at equal intervals in the Y direction.

[0018] As shown in FIG. 1, in this embodiment, the components that make up the shelf section 10 are aligning members 11. Specifically, each of the aligning members 11 is arranged on the shelf section 10 so as to extend along the X direction. The upper surfaces of the multiple aligning members 11 aligned in the Y direction form a support surface (placing surface) for the article A on the shelf section 10. The article A is supported by the multiple aligning members 11. As shown in FIG. 14 of a third embodiment described later, in this embodiment, the aligning member 11 is a groove-shaped member having a cross-sectional shape with an open lower side Z2, and includes an upper portion that forms the support surface for the article A, and side portions that extend from both ends of the upper portion in the Y direction to the lower side Z2.

[0019] In this embodiment, the article storage facility 100 is equipped with a transfer machine 9 that travels along the Y direction and transfers articles A between the storage shelves 1. The transfer machine 9 travels along the Y direction between the pair of storage shelves 1 in the X direction. The transfer machine 9 is configured to be able to transfer articles A to either of the pair of storage shelves 1. In the example shown in FIG. 1, the transfer machine 9 is configured to transport articles A one by one. The transfer machine 9 can also be configured to transport multiple articles A (for example, two articles A) together.

[0020] The transfer machine 9 illustrated in Fig. 1 is configured as follows. The transfer machine 9 includes a traveling body 90 that travels along the Y direction, and a transfer device 92 that transfers an article A. The traveling body 90 includes a plurality of wheels 91 that roll on the traveling surface of the rail 2, and at least some of the plurality of wheels 91 are rotationally driven by a driving device such as an electric motor, causing the traveling body 90 to travel along the rail 2. The rail 2 is configured, for example, by connecting a plurality of rail members in the Y direction.

[0021] The transfer device 92 moves the item A along the X direction to transfer the item A between the transfer target location (such as the shelf portion 10 of the storage shelf 1). For example, the transfer device 92 can be configured to deliver the item A to the transfer target location by pushing out the item A using an abutment portion (for example, a hook that can swing around an axis along the X direction) not shown that abuts against the item A, and to receive the item A from the transfer target location by pulling in the item A using the abutment portion.

[0022] The rails 2 on which the transfer machine 9 (specifically, the running body 90) travels are arranged to extend along the Y direction. In this embodiment, each of a pair of storage shelves 1 is equipped with rails 2. The transfer machine 9 is equipped with wheels 91 that roll on the running surface of the rails 2 of one of the storage shelves 1, and wheels 91 that roll on the running surface of the rails 2 of the other storage shelf 1. In this way, in this embodiment, the running path of the transfer machine 9 is formed by the pair of rails 2. The pair of rails 2 are arranged at the same height and spaced apart in the X direction.

[0023] As shown in FIG. 1, the storage shelf 1 is equipped with support columns 12 extending in the vertical direction Z. The support columns 12 are erected on the floor so as to extend from the floor to the upper side Z1. A plurality of support columns 12 are arranged in a line in the Y direction at each of a plurality of positions in the X direction. Specifically, a plurality of support columns 12 are arranged in the Y direction at X direction positions corresponding to both ends of each storage shelf 1 in the X direction. The rail 2 is connected to the plurality of support columns 12 arranged in the Y direction, and is thereby supported by these plurality of support columns 12. In this embodiment, a second surface S2 (see FIG. 4), which will be described later, of the rail 2 is connected to the support columns 12, for example, via a bracket.

[0024] The rails 2 are connected to the X-direction ends of the aligning members 11 that constitute the shelf section 10, and the aligning members 11 are supported by the support columns 12 via the rails 2. In the example shown in FIG. 1 , one end of the aligning members 11 in the X-direction (the side where the transfer machine 9 is arranged) is connected to the rails 2, and the other end of the aligning members 11 in the X-direction is connected to a horizontal member 15 that connects adjacent support columns 12 in the Y-direction. Therefore, in the example shown in FIG. 1 , the aligning members 11 are supported by the support columns 12 via the rails 2 and the horizontal member 15. Note that if rails 2 are provided instead of the horizontal members 15 and the transfer machines 9 travel on both sides of the storage shelf 1 in the X-direction, both end portions of the aligning members 11 in the X-direction are connected to the rails 2.

[0025] In this embodiment, the travel path of the transfer machine 9 is formed corresponding to each of the multiple shelf sections 10. Specifically, a pair of rails 2 forming the travel path of the transfer machine 9 is provided at a height corresponding to each of the multiple shelf sections 10. Although FIG. 1 shows only the transfer machine 9 arranged on the travel path of the topmost of the multiple travel paths, for example, one or more transfer machines 9 are arranged on each of the multiple travel paths. The transfer machine 9 transfers an article A between the travel path on which the transfer machine 9 is arranged and the shelf section 10 on the same level as the travel path on which the transfer machine 9 is arranged.

[0026] In this embodiment, the article storage facility 100 includes an intermediary section 13 and an elevating conveying device 14. An intermediary section 13 is provided corresponding to each of the multiple shelf sections 10, and the transfer machine 9 conveys article A between the shelf sections 10 arranged on the same level and the intermediary section 13. The elevating conveying device 14 conveys article A in the vertical direction Z. In the example shown in FIG. 1, the intermediary section 13 and the elevating conveying device 14 are provided with conveyors that convey article A in the Y direction.

[0027] 1 , the relay section 13 and the lifting and conveying device 14 are provided on both sides in the X direction, and the relay section 13 and the lifting and conveying device 14 on one side in the X direction are used for receiving the item A, and the relay section 13 and the lifting and conveying device 14 on the other side in the X direction are used for retrieving the item A.

[0028] 1, the relay section 13 and the lifting and conveying device 14 are arranged on the second side Y2 in the Y direction with respect to the storage shelf 1, but the relay section 13 and the lifting and conveying device 14 may also be arranged on the first side Y1 in the Y direction with respect to the storage shelf 1. Furthermore, the relay section 13 and the lifting and conveying device 14 may also be arranged on both sides of the storage shelf 1 in the Y direction.

[0029] The article storage facility 100 is equipped with a scaffolding 3 that is configured to be detachable from a pair of shelves 1. The scaffolding 3 is normally detached from the pair of shelves 1 and is attached to the pair of shelves 1 only when in use. The scaffolding 3 is attached so that it is placed from the upper side Z1 on the installation portion of the pair of shelves 1 (in this embodiment, a pair of rails 2 arranged at the same height). The scaffolding 3 is detached from the pair of shelves 1 by moving it to the upper side Z1. The scaffolding 3 is used when a worker W performs work (for example, maintenance work on the shelves 1 or the transfer machine 9). Maintenance work on the shelves 1 is, for example, work to correct the position of an article A stored on the shelf section 10. Maintenance work on the transfer machine 9 is, for example, work to restore the transfer machine 9 when an abnormality such as a breakdown has occurred.

[0030] Only one scaffolding 3 may be attached, or multiple scaffoldings 3 may be attached. When multiple scaffoldings 3 are attached, for example, the multiple scaffoldings 3 may be arranged in a staircase-like manner, or the multiple scaffoldings 3 may be arranged side by side at the same height. FIG. 2 shows, as an example of how the scaffoldings 3 are used, a state in which multiple scaffoldings 3 are arranged in a staircase-like manner so that a worker W can climb up. In this example, it is assumed that the worker W climbs up to the top scaffolding 3 to perform work, and an additional scaffolding 8, which will be described later, is placed in a position adjacent to the top scaffolding 3 on the first side Y1 in the Y direction. This ensures a large width in the Y direction of the tread surface (the surface on which the worker W stands) on the top step where the worker W works.

[0031] The scaffolding 3 is arranged to bridge the gap between the pair of storage shelves 1 in the X direction. In this embodiment, as shown in Fig. 5, the scaffolding 3 is arranged to bridge the gap between the pair of storage shelves 1 in the X direction and is configured to be supported from the underside Z2 by the rails 2 of each of the pair of storage shelves 1. The rails 2 have a portion on which the wheels 91 of the transfer machine 9 roll and a portion to which the alignment member 11 is connected, and the scaffolding 3 is supported on a portion of the rails 2 that is different from these two portions.

[0032] Specifically, in this embodiment, as shown in Figures 3 and 4, the rail 2 is equipped with a mounting surface forming section 20 that forms a mounting surface on which the scaffolding 3 (specifically, a bottom surface section 30b described later) is placed, and a running surface forming section 21 that forms a running surface (a surface on which the wheels 91 roll) of the transfer machine 9. The mounting surface is formed by the upper surface of the mounting surface forming section 20, and the running surface is formed by the upper surface of the running surface forming section 21. The mounting surface forming section 20 is arranged on the upper side Z1 above the running surface forming section 21. The scaffolding 3 is supported from the lower side Z2 by the rail 2 while placed on the mounting surface formed by the mounting surface forming section 20.

[0033] The rail 2 further includes a connecting portion 22 that connects the placing surface forming portion 20 and the running surface forming portion 21. The connecting portion 22 connects the ends of the placing surface forming portion 20 and the running surface forming portion 21 on the same side in the X direction (the left side in FIG. 4). Of the two surfaces of the connecting portion 22 in the X direction, the surface on which the placing surface forming portion 20 and the running surface forming portion 21 are arranged with respect to the connecting portion 22 (the right side in FIG. 4) is referred to as a first surface S1, and the surface on the opposite side is referred to as a second surface S2. The rail 2 is arranged on each of the pair of shelves 1 with the first surface S1 facing the space between the pair of shelves 1. The end of the alignment member 11 in the X direction is connected to the rail 2 from the side of the second surface S2. For example, an engagement portion (e.g., a slit) with which the arrangement member 11 engages is formed in the connecting portion 22, or in the placing surface forming portion 20, or across the connecting portion 22 and the placing surface forming portion 20. The placing surface forming portion 20, the running surface forming portion 21, and the connecting portion 22 (in this embodiment, a first extending portion 23 and a second extending portion 24, which will be further described below) are integrally formed.

[0034] The rail 2 further includes a first extension portion 23 and a second extension portion 24. The first extension portion 23 is formed to extend downward Z2 from the end of the placing surface forming portion 20 on the side away from the connecting portion 22 in the X direction (the right side in FIG. 4). As will be described later, the first extension portion 23 restricts movement of the scaffolding 3 in the X direction. The second extension portion 24 is formed to extend upward Z1 from the end of the running surface forming portion 21 on the side away from the connecting portion 22 in the X direction (the right side in FIG. 4). The second extension portion 24 prevents the wheels 91 of the transfer machine 9 from falling off the rail 2.

[0035] In this embodiment, the portion of the scaffolding 3 on the second X-direction side X2 is configured similarly to the portion of the scaffolding 3 on the first X-direction side X1. Specifically, the portion of the scaffolding 3 on the second X-direction side X2 corresponds to the portion of the scaffolding 3 on the first X-direction side X1 flipped in the X direction. That is, the portion of the scaffolding 3 on the first X-direction side X1 and the portion of the scaffolding 3 on the second X-direction side X2 are configured to be mirror-symmetrical to each other with respect to a plane perpendicular to the X direction. Therefore, the following description of the scaffolding 3 basically applies to both portions of the scaffolding 3 on both sides in the X direction. Similarly, the portion of the second X-direction side X2 of the additional scaffolding 8 is configured similarly to the portion of the first X-direction side X1 of the additional scaffolding 8. Therefore, the following description of the additional scaffolding 8 basically applies to both portions of the additional scaffolding 8 on both sides in the X direction.

[0036] As shown in FIG. 5 , in this embodiment, the item storage facility 100 includes a first scaffolding 3A as the scaffolding 3. The first scaffolding 3A includes a scaffolding main body 30 that forms a tread surface. The tread surface is formed by the upper surface of the scaffolding main body 30. The scaffolding main body 30 is formed in a plate shape that conforms to a horizontal plane. The upper surface of the scaffolding main body 30 does not need to be flat, and the upper surface of the scaffolding main body 30 may have an uneven surface. Furthermore, the scaffolding main body 30 may have a through-hole that penetrates the scaffolding main body 30 in the vertical direction Z. In this embodiment, the dimension of the scaffolding main body 30 in the Y direction is smaller than the dimension of the scaffolding main body 30 in the X direction. That is, the first scaffolding 3A is attached to the pair of storage shelves 1 with the longitudinal direction of the scaffolding main body 30 aligned along the X direction. The following description will be given of a state in which the first scaffolding 3A and the additional scaffolding 8 are attached to the pair of storage shelves 1, unless otherwise specified.

[0037] 6, 8, 9, and 14, the first X-direction side X1 is the outside in the X direction, and the second X-direction side X2 is the inside in the X direction. In the following description of the first scaffolding 3A and the additional scaffolding 8, the side toward the center of the scaffolding main body 30 (the additional scaffolding main body 80 described later in the case of the additional scaffolding 8) in the X direction is referred to as the "inside in the X direction," and the opposite side is referred to as the "outside in the Y direction." In Figs. 7, 11, and 12, the first X-direction side X1 is the inside in the X direction, and the second X-direction side X2 is the outside in the X direction. In addition, in the following description of the first scaffolding 3A and the additional scaffolding 8, the side toward the center of the scaffolding main body 30 (the additional scaffolding main body 80 in the case of the additional scaffolding 8) in the Y direction is referred to as the "inside in the Y direction," and the opposite side is referred to as the "outside in the Y direction." 8 and 9, the first side Y1 in the Y direction is the outer side in the Y direction, and the second side Y2 in the Y direction is the inner side in the Y direction.

[0038] In this embodiment, the first scaffolding 3A has side surfaces 30a extending downward Z2 from both ends of the scaffolding main body 30 in the Y direction, and a bottom surface 30b extending inward in the Y direction from the end of the side surface 30a on the lower side Z2. The side surfaces 30a and the bottom surface 30b are formed integrally with the scaffolding main body 30, for example. As shown in FIGS. 5 and 7, the first scaffolding 3A is attached to a pair of storage shelves 1 so that the bottom surface 30b is placed on the mounting surface forming portion 20 of the rail 2.

[0039] The first scaffolding 3A is arranged so as to bridge the X-direction gap between the pair of storage shelves 1 and is provided with a locking structure 4 that is locked to each of the pair of storage shelves 1. The locking structure 4 is provided with a Y-direction restricting structure 4Y (see FIG. 6) that restricts movement of the first scaffolding 3A in the Y-direction. In this embodiment, the locking structure 4 further includes an X-direction restricting structure 4X (see FIG. 7) that restricts movement of the first scaffolding 3A in the X-direction. The Y-direction restricting structure 4Y and the X-direction restricting structure 4X may be configured to restrict movement of the first scaffolding 3A while allowing it within a predetermined range (for example, a range corresponding to the gap between the components). Allowing movement of the first scaffolding 3A within a predetermined range makes it easier to install the first scaffolding 3A.

[0040] The "structures" in the locking structure 4, the Y-direction restricting structure 4Y, and the X-direction restricting structure 4X may be formed using a single member or multiple members. In this embodiment, the locking structure 4 is formed using multiple members including the members that form the Y-direction restricting structure 4Y and the members that form the X-direction restricting structure 4X. In this embodiment, the Y-direction restricting structure 4Y is formed using multiple members including a first restricting member 71 and a second restricting member 72, which will be described later. In this embodiment, the X-direction restricting structure 4X is formed using multiple members including a third restricting member 73 and a fourth restricting member 74, which will be described later.

[0041] Furthermore, the locking structure 4 can also be realized by interchanging the configuration provided on the first scaffold 3A side with the configuration provided on the storage shelf 1 side, and the locking structure 4 may have either configuration. Thus, for example, the locking structure 4 may have a protrusion that engages with a hole provided on the storage shelf 1 side, or may have a hole that engages with a protrusion provided on the storage shelf 1 side. Similarly, the Y-direction restricting structure 4Y and the X-direction restricting structure 4X can also be realized by interchanging the configuration provided on the first scaffold 3A side with the configuration provided on the storage shelf 1 side, and the Y-direction restricting structure 4Y and the X-direction restricting structure 4X may have either configuration.

[0042] As shown in FIG. 5, the first scaffolding 3A (specifically, the locking structure 4) includes a first restricting member 71 and a second restricting member 72. The first restricting member 71 and the second restricting member 72 are provided at the ends of the first scaffolding 3A in the X direction. In this embodiment, the first restricting member 71 is disposed on the second side Y2 in the Y direction relative to the second restricting member 72. The first restricting member 71 and the second restricting member 72 are locked to the storage shelves 1 (specifically, the alignment member 11) in a state in which the first scaffolding 3A is disposed so as to bridge between the pair of storage shelves 1 in the X direction.

[0043] In this embodiment, the first scaffolding 3A includes a bracket 31 for fixing a first restricting member 71 and a second restricting member 72. As shown in FIG. 9, the bracket 31 is fixed to the side surface portion 30a (specifically, the surface of the side surface portion 30a facing inward in the Y direction) while being placed on the bottom surface portion 30b. As shown in FIG. 6, the first restricting member 71 is fixed to the bracket 31 by a first bolt B1 (an example of a fastening member), and the second restricting member 72 is fixed to the bracket 31 by a second bolt B2 (an example of a fastening member). The first restricting member 71 is fixed by one first bolt B1, and the second restricting member 72 is fixed by one second bolt B2. The first bolt B1 is disposed with its shank oriented along the vertical direction Z, and the second bolt B2 is disposed with its shank oriented along the vertical direction Z.

[0044] The first restricting member 71 has a first opposing portion 41. A fixed portion of the first restricting member 71 that is fixed to the bracket 31 is disposed on the upper side Z1 with respect to the bracket 31. The first opposing portion 41 is formed to extend from an end portion of the fixed portion of the first restricting member 71 that is on the outer side in the X direction (first side X1 in the X direction in FIG. 6) to a lower side Z2. Rotation of the first restricting member 71 (in other words, the first opposing portion 41) around its axis along the up-down direction Z is restricted when a portion of the first restricting member 71 that is disposed on the outer side in the X direction with respect to the bracket 31 (a portion on the upper side Z1 above the first opposing portion 41 in the example shown in FIG. 6) abuts against the bracket 31.

[0045] The second restricting member 72 has a second opposing portion 42. A fixed portion of the second restricting member 72 that is fixed to the bracket 31 is disposed on the upper side Z1 with respect to the bracket 31. The second opposing portion 42 is formed to extend from an outer end of the fixed portion of the second restricting member 72 in the X direction to a lower side Z2. Rotation of the second restricting member 72 (in other words, the second opposing portion 42) around its axis in the up-down direction Z is restricted when a portion of the second restricting member 72 that is disposed on the outer side in the X direction with respect to the bracket 31 (in the example shown in FIG. 6, a portion on the upper side Z1 above the second opposing portion 42) abuts against the bracket 31.

[0046] Here, one alignment member 11 on each of a pair of storage shelves 1 (specifically, a pair of shelf portions 10 on the same tier) is referred to as a first alignment member 11A. The first alignment member 11A on one of the pair of storage shelves 1 and the first alignment member 11A on the other of the pair of storage shelves 1 are alignment members 11 arranged at the same position in the Y direction. Furthermore, another alignment member 11 other than the first alignment member 11A on each of the pair of storage shelves 1 (specifically, a pair of shelf portions 10 on the same tier) is referred to as a second alignment member 11B. The second alignment member 11B on one of the pair of storage shelves 1 and the second alignment member 11B on the other of the pair of storage shelves 1 are alignment members 11 arranged at the same position in the Y direction.

[0047] When the first scaffolding 3A is attached to the pair of storage shelves 1, the first opposing portion 41 is arranged to face the first alignment member 11A from the first side Y1 in the Y direction, and the second opposing portion 42 is arranged to face the second alignment member 11B from the second side Y2 in the Y direction. In this embodiment, the second alignment member 11B is the alignment member 11 adjacent to the first alignment member 11A on the first side Y1 in the Y direction. Therefore, the first opposing portion 41 and the second opposing portion 42 are arranged to face the opposing surfaces of the two alignment members 11 adjacent in the Y direction. Note that "facing" includes both cases where they are in contact (facing each other with no gap) and cases where they are not in contact (facing each other with a gap).

[0048] Because the first opposing portion 41 and the second opposing portion 42 as described above are provided on the first scaffolding 3A, movement of the first scaffolding 3A toward the first side Y1 in the Y direction is restricted by the second opposing portion 42, and movement of the first scaffolding 3A toward the second side Y2 in the Y direction is restricted by the first opposing portion 41. In this way, the Y-direction restricting structure 4Y that restricts movement of the first scaffolding 3A in the Y direction includes the first opposing portion 41 that faces the first array member 11A of each of the pair of storage shelves 1 from the first side Y1 in the Y direction, and the second opposing portion 42 that faces the second array member 11B of each of the pair of storage shelves 1 from the second side Y2 in the Y direction.

[0049] In this embodiment, the first opposing portion 41 and the second opposing portion 42 are formed in the shape of plates perpendicular to the X direction. Therefore, it is easy to keep the amount of outward protrusion of the first opposing portion 41 and the second opposing portion 42 in the X direction relative to the rail 2 small, and as a result, as shown in Figures 5 and 7, even if an item A is placed near the rail 2 on the shelf unit 10, it is easy to place the first scaffolding 3A while avoiding interference with the item A.

[0050] In this embodiment, the Y-direction restricting structure 4Y includes a gap adjustment mechanism 5 that adjusts the gap in the Y direction between the first opposing portion 41 and the second opposing portion 42. As shown in FIG. 6 , in this embodiment, the gap adjustment mechanism 5 includes an elongated hole 50 through which the shank of the first bolt B1 and the shank of the second bolt B2 are inserted. In this example, the elongated hole 50 is formed in the bracket 31. The elongated hole 50 is formed long in the Y direction so that the Y-direction positions of the first bolt B1 and the second bolt B2 can be adjusted. Therefore, by loosening the first bolt B1, the Y-direction position of the first restricting member 71 including the first opposing portion 41 can be adjusted, and by loosening the second bolt B2, the Y-direction position of the second restricting member 72 including the second opposing portion 42 can be adjusted. This allows the Y-direction gap between the first opposing portion 41 and the second opposing portion 42 to be adjusted.

[0051] In this embodiment, the first scaffolding 3A (specifically, the locking structure 4) further includes a third restricting member 73 and a fourth restricting member 74. The third restricting member 73 and the fourth restricting member 74 are provided at the ends of the first scaffolding 3A in the X direction. The third restricting member 73 and the fourth restricting member 74 are formed in a plate shape perpendicular to the Y direction. As shown in FIGS. 5 and 7, the third restricting member 73 is fixed to one of the pair of side surface portions 30a on the second Y direction side Y2 (specifically, the surface of the side surface portion 30a facing outward in the Y direction). As shown in FIGS. 8 and 9, the fourth restricting member 74 is fixed to one of the pair of side surface portions 30a on the first Y direction side Y1 (specifically, the surface of the side surface portion 30a facing outward in the Y direction). The third regulating member 73 and the fourth regulating member 74 are engaged with the storage shelf 1 (specifically, the rail 2) when the first scaffolding 3A is positioned so as to span between the pair of storage shelves 1 in the X direction.

[0052] As shown in FIGS. 5 and 7, when the first scaffolding 3A is attached to the pair of storage shelves 1, the third restricting member 73 is arranged to face the rail 2 (specifically, the first extending portion 23) from the inside in the X direction (the first side X1 in the X direction in FIG. 7). Although not shown, when the first scaffolding 3A is attached to the pair of storage shelves 1, the fourth restricting member 74 is arranged to face the rail 2 (specifically, the first extending portion 23) from the inside in the X direction. Therefore, movement of the first scaffolding 3A toward the first side X1 in the X direction is restricted by the third restricting member 73 and the fourth restricting member 74 provided at the end of the first scaffolding 3A on the first side X1 in the X direction, and movement of the first scaffolding 3A toward the second side X2 in the X direction is restricted by the third restricting member 73 and the fourth restricting member 74 provided at the end of the first scaffolding 3A on the second side X2 in the X direction.

[0053] Thus, in this embodiment, the X-direction restricting structure 4X that restricts movement of the first foothold 3A in the X direction includes a third opposing portion (third restricting member 73) and a fourth opposing portion (fourth restricting member 74) that face the rail 2 from the inside in the X direction on each of the pair of storage shelves 1. The third opposing portion and the fourth opposing portion face the rail 2 from the inside in the X direction at different positions from each other in the Y direction.

[0054] In this embodiment, the members constituting the X-direction restricting structure 4X are separate from the members constituting the Y-direction restricting structure 4Y, but the X-direction restricting structure 4X can also be constituted using the members constituting the Y-direction restricting structure 4Y. In this configuration, the structure of the first scaffold 3A can be simplified.

[0055] Specifically, as shown in FIG. 6 , when the first scaffolding 3A is attached to the pair of storage shelves 1, the first opposing portion 41 and the second opposing portion 42 are arranged to face the rail 2 from the outside in the X direction (the first side X1 in the X direction in FIG. 6 ). Therefore, even if the third restricting member 73 and the fourth restricting member 74 are not provided, the movement of the first scaffolding 3A toward the first side X1 in the X direction is restricted by the first opposing portion 41 and the second opposing portion 42 provided at the end of the first scaffolding 3A on the second side X2 in the X direction, and the movement of the first scaffolding 3A toward the second side X2 in the X direction is restricted by the first opposing portion 41 and the second opposing portion 42 provided at the end of the first scaffolding 3A on the first side X1 in the X direction. In this case, it can be said that the X-direction restricting structure 4X includes the first opposing portion 41 and the second opposing portion 42 that face the rail 2 of each of the pair of storage shelves 1 from the outside in the X direction.

[0056] In this embodiment, the item storage facility 100 includes an additional scaffolding 8 that is arranged adjacent to the first scaffolding 3A on the first side Y1 in the Y direction. By arranging the additional scaffolding 8 adjacent to the first scaffolding 3A on the first side Y1 in the Y direction, it is possible to ensure a larger width of the tread in the Y direction compared to when the first scaffolding 3A is used alone.

[0057] 8 and 9, the first scaffolding 3A has a connecting part 32 that is arranged to protrude toward the first side Y1 in the Y direction relative to the scaffolding main body 30 and is connected to the additional scaffolding 8. The connecting part 32 is provided at the end of the first scaffolding 3A in the X direction. In this embodiment, the connecting part 32 is formed integrally with the fourth restricting member 74.

[0058] The connecting portion 32 has a fitting recess 33 into which the additional scaffolding 8 fits from the upper side Z1. The fitting recess 33 is formed so as to open to the upper side Z1 and recessed to the lower side Z2. In this embodiment, the fitting recess 33 is formed so as to open to both sides in the X direction. Specifically, the connecting portion 32 has a bottom portion extending from the end of the fourth restricting member 74 on the lower side Z2 to the first side Y1 in the Y direction, and a side portion extending from the end of the bottom portion on the first side Y1 in the Y direction to the upper side Z1. The fitting recess 33 is formed by being surrounded by the fourth restricting member 74, the bottom portion, and the side portion.

[0059] The connecting portion 32 further includes a guide portion 34. The guide portion 34 is provided so as to extend toward the first side Y1 in the Y direction relative to the fitting recess 33. The guide portion 34 is disposed so as to be inclined toward the upper side Z1 as it approaches the first side Y1 in the Y direction. Note that the connecting portion 32 may also be configured without the guide portion 34.

[0060] As shown in Fig. 5, the additional scaffolding 8 comprises an additional scaffolding main body part 80 that forms a tread surface. The tread surface is formed by the upper surface of the additional scaffolding main body part 80. The tread surface formed on the additional scaffolding main body part 80 is arranged at the same height (the same or approximately the same height) as the tread surface formed on the scaffolding main body part 30. The additional scaffolding 8 comprises side surface parts 80a that extend downward Z2 from both ends in the Y direction of the additional scaffolding main body part 80. The side surface parts 80a are formed integrally with the additional scaffolding main body part 80, for example.

[0061] The additional scaffolding main body part 80 is formed in the shape of a plate that fits along a horizontal plane. The top surface of the additional scaffolding main body part 80 does not need to be flat, and the top surface of the additional scaffolding main body part 80 may be uneven. Furthermore, a through-hole that penetrates the additional scaffolding main body part 80 in the vertical direction Z may be formed in the additional scaffolding main body part 80. In this embodiment, the dimension of the additional scaffolding main body part 80 in the Y direction is smaller than the dimension of the additional scaffolding main body part 80 in the X direction. In other words, the additional scaffolding 8 is attached to the pair of storage shelves 1 in an orientation where the longitudinal direction of the additional scaffolding main body part 80 is along the X direction.

[0062] In this embodiment, the extension scaffolding 8 does not have a structure that restricts movement of the extension scaffolding 8 in the Y direction. On the other hand, the extension scaffolding 8 does have a structure that restricts movement of the extension scaffolding 8 in the X direction. Specifically, as shown in FIG. 5 , the extension scaffolding 8 has a fifth restricting member 75 and a sixth restricting member 76. The fifth restricting member 75 and the sixth restricting member 76 are provided at the ends of the extension scaffolding 8 in the X direction. The fifth restricting member 75 and the sixth restricting member 76 are formed in a plate shape that is perpendicular to the Y direction. The fifth restricting member 75 is fixed to one of the pair of side surface portions 80a on the second Y-direction side Y2 (specifically, the surface of the side surface portion 80a facing outward in the Y direction), and the sixth restricting member 76 is fixed to one of the pair of side surface portions 80a on the first Y-direction side Y1 (specifically, the surface of the side surface portion 80a facing outward in the Y direction).

[0063] When the additional scaffolding 8 is attached to the pair of storage shelves 1, the fifth restricting member 75 and the sixth restricting member 76 are arranged to face the rail 2 (specifically, the first extending portion 23) from the inside in the X direction. Therefore, movement of the additional scaffolding 8 towards the first side X1 in the X direction is restricted by the fifth restricting member 75 and the sixth restricting member 76 provided at the end of the additional scaffolding 8 on the first side X1 in the X direction, and movement of the additional scaffolding 8 towards the second side X2 in the X direction is restricted by the fifth restricting member 75 and the sixth restricting member 76 provided at the end of the additional scaffolding 8 on the second side X2 in the X direction.

[0064] In this embodiment, the dimension in the X direction of the additional scaffolding main body 80 is shorter than the separation distance in the X direction between the pair of rails 2 (here, the separation distance in the X direction between the placing surface forming portion 20 of one rail 2 and the placing surface forming portion 20 of the other rail 2). As will be described below, the additional scaffolding 8 is configured to be supported from the lower side Z2 by the pair of storage shelves 1 on the first side Y1 in the Y direction, and to be supported from the lower side Z2 by the scaffolding 3 on the second side Y2 in the Y direction.

[0065] The additional scaffolding 8 includes a pair of supported protrusions 81 and a fitted portion 82. While FIG. 5 shows only the supported protrusion 81 on the first side X1 in the X direction out of the pair of supported protrusions 81, the pair of supported protrusions 81 are formed to protrude outward in the X direction from the side portion of the additional scaffolding main body 80 on the first side Y1 in the Y direction. When the additional scaffolding 8 is attached to the pair of storage shelves 1, the pair of supported protrusions 81 are supported from the lower side Z2 by each of the pair of storage shelves 1. Here, when the pair of supported protrusions 81 are placed on the placement surface forming portion 20, they are supported from the lower side Z2 by the rails 2 of each of the pair of storage shelves 1. In this embodiment, the supported protrusions 81 are formed integrally with the sixth restricting member 76.

[0066] The fitted portion 82 is provided on a side portion of the additional scaffolding main body 80 on the second side Y2 in the Y direction. The fitted portion 82 is provided on the end portion of the additional scaffolding 8 in the X direction. As shown in FIG. 9 , in this embodiment, the fitted portion 82 is formed integrally with the fifth restricting member 75. Then, when the first scaffolding 3A and the additional scaffolding 8 are attached to the pair of storage shelves 1, the fitted portion 82 fits into the fitting recess 33 of the connecting portion 32. Because movement of the first scaffolding 3A in the Y direction is restricted, movement of the additional scaffolding 8 in the Y direction is also restricted by fitting the fitted portion 82 into the fitting recess 33. In this embodiment, the additional scaffolding 8 is configured so that the engaging portion 82 is supported from the lower side Z2 by the connecting portion 32 (specifically, the bottom of the engaging recess 33), and thus the side portion of the additional scaffolding main body portion 80 on the second side Y2 in the Y direction is supported from the lower side Z2.

[0067] In this way, the additional scaffolding 8 is configured to be supported from the lower side Z2 by the pair of storage shelves 1 on the first side Y1 in the Y direction, and to be supported from the lower side Z2 by the scaffolding 3 (specifically, the connecting portion 32) on the second side Y2 in the Y direction. Therefore, even if an attempt is made to use the additional scaffolding 8 alone, which is not provided with a structure to restrict movement in the Y direction, the additional scaffolding 8 is supported from the lower side Z2 only at the side portion on the first side Y1 in the Y direction by the pair of storage shelves 1, and therefore the side portion on the second side Y2 in the Y direction of the additional scaffolding 8 is lowered to the lower side Z2. Therefore, it is easy to avoid the additional scaffolding 8 being used alone by mistake.

[0068] The position and dimensions of the fitting recess 33 in the Y direction are set so that the size of the gap between the first scaffolding 3A and the additional scaffolding 8 is within a range that ensures the safety of the worker W (for example, 30 mm or less). Two first scaffoldings 3A can be lined up in the Y direction without using the additional scaffolding 8, but in this case, the worker W may need to adjust the Y direction positions of the first opposing portion 41 and the second opposing portion 42 on site to reduce the gap between the two first scaffoldings 3A. In contrast, when the additional scaffolding 8 is used, such on-site work is unnecessary, and convenience and safety for the worker W can be improved.

[0069] Second Embodiment A second embodiment of the article storage facility will be described with reference to the drawings (FIGS. 10 to 12). The following description will focus on the differences from the first embodiment. Points that are not specifically mentioned are the same as those in the first embodiment, and the same reference numerals will be used to omit detailed description.

[0070] As shown in Fig. 10, in this embodiment, the article storage facility 100 includes a second scaffolding 3B as the scaffolding 3. Unless otherwise specified, the second scaffolding 3B is similar to the first scaffolding 3A of the first embodiment. As shown in Figs. 11 and 12, in this embodiment, the first regulating member 71 is disposed on the first side Y1 in the Y direction relative to the second regulating member 72. Furthermore, in this embodiment, as will be described below, the second opposing portion 42 is disposed so as to oppose the first array member 11A from the second side Y2 in the Y direction.

[0071] As shown in FIG. 11 , in this embodiment, the fixed portion of the first restricting member 71 that is fixed to the bracket 31 is disposed on the lower side Z2 with respect to the bracket 31. The first opposing portion 41 is formed so as to extend downwardly Z2 from the inner end of the fixed portion of the first restricting member 71 in the Y direction. In this embodiment, the first opposing portion 41 is formed in a plate shape that is perpendicular to the Y direction. As shown in FIG. 12 , the first restricting member 71 includes a first claw portion 71a that extends upwardly Z1 from the fixed portion and is disposed inside the elongated hole 50. Rotation of the first restricting member 71 (in other words, the first opposing portion 41) around its axis along the up-down direction Z is restricted by the first claw portion 71a abutting against the inner surface of the elongated hole 50.

[0072] As shown in FIG. 11 , in this embodiment, the fixed portion of the second restricting member 72 that is fixed to the bracket 31 is disposed on the lower side Z2 with respect to the bracket 31. The second opposing portion 42 is formed so as to extend downwardly Z2 from the inner end of the fixed portion of the second restricting member 72 in the Y direction. In this embodiment, the second opposing portion 42 is formed in a plate shape that is perpendicular to the Y direction. As shown in FIGS. 11 and 12 , the second restricting member 72 includes a second claw portion 72a that extends upwardly Z1 from the fixed portion and is disposed inside the elongated hole 50. Rotation of the second restricting member 72 (in other words, the second opposing portion 42) around its axis in the up-down direction Z is restricted by the second claw portion 72a abutting against the inner surface of the elongated hole 50.

[0073] When the second scaffolding 3B is attached to the pair of storage shelves 1, the first opposing portion 41 is arranged to face the first alignment member 11A from the first side Y1 in the Y direction, and the second opposing portion 42 is arranged to face the first alignment member 11A from the second side Y2 in the Y direction. That is, the first opposing portion 41 and the second opposing portion 42 are arranged to face surfaces of one alignment member 11 that face opposite each other. In this manner, in this embodiment, the Y-direction regulating structure 4Y includes the first opposing portion 41 that faces the first alignment member 11A, which is one alignment member 11 in each of the pair of storage shelves 1, from the first side Y1 in the Y direction, and the second opposing portion 42 that faces the first alignment member 11A in each of the pair of storage shelves 1 from the second side Y2 in the Y direction.

[0074] Third Embodiment A third embodiment of the article storage facility will be described with reference to the drawings (FIGS. 13 and 14). The following description will focus on differences from the second embodiment. Points that are not specifically mentioned are the same as those in the second embodiment, and the same reference numerals will be used to omit detailed description.

[0075] As shown in Fig. 13, in this embodiment, the item storage facility 100 is provided with a third scaffolding 3C as the scaffolding 3. In this embodiment, as shown in Fig. 13, the third scaffolding 3C is used to install the scaffolding main body 30 at a height between two shelf sections 10 adjacent in the vertical direction Z when the scaffolding main body 30 is set in a stepped shape to form stepped treads. Therefore, the item storage facility 100 is provided with a second scaffolding 3B in addition to the third scaffolding 3C as the scaffolding 3. Note that the item storage facility 100 may also be configured to be provided with a first scaffolding 3A in addition to the third scaffolding 3C as the scaffolding 3.

[0076] The third scaffolding 3C will be described below, but unless otherwise specified, it will be considered the same as the second scaffolding 3B. As shown in FIG. 14 , the third scaffolding 3C includes a scaffolding main body 30, a support portion 35, and a connecting member 36. The support portion 35 includes a locking structure 4 (here, a Y-direction restricting structure 4Y). In this embodiment, an elongated hole 50 is formed in the support portion 35, and a first restricting member 71 and a second restricting member 72 are fixed to the support portion 35. The third scaffolding 3C is attached to a pair of storage shelves 1 so that the support portion 35 is placed on the mounting surface forming portion 20 of the rail 2.

[0077] In this embodiment, the first regulating member 71 is disposed on the second side Y2 in the Y direction relative to the second regulating member 72. In this embodiment, the Y-direction regulating structure 4Y includes a first opposing portion 41 that faces the first array member 11A of each of the pair of storage shelves 1 from the first side Y1 in the Y direction, and a second opposing portion 42 that faces the second array member 11B of each of the pair of storage shelves 1 from the second side Y2 in the Y direction. That is, the third scaffolding 3C is attached to the pair of storage shelves 1 so that the first opposing portion 41 and the second opposing portion 42 face opposing surfaces of two array members 11 adjacent in the Y direction, respectively. Note that the third scaffolding 3C may also be attached to the pair of storage shelves 1 so that the first opposing portion 41 and the second opposing portion 42 face opposing surfaces of one array member 11 that face in opposite directions, similar to the second scaffolding 3B.

[0078] In this embodiment, the scaffolding main body 30 is disposed on the lower side Z2 of the support 35. The distance in the vertical direction Z between the support 35 and the scaffolding main body 30 is smaller than the distance in the vertical direction Z between two shelf portions 10 adjacent in the vertical direction Z in each of the pair of storage shelves 1. Therefore, when the third scaffolding 3C is attached to the pair of storage shelves 1, the scaffolding main body 30 is disposed at a height between the shelf portion 10 to which the support 35 is attached and the shelf portion 10 one level below this shelf portion 10.

[0079] The connecting members 36 connect the support parts 35 and the scaffolding main body part 30 in the vertical direction Z. The connecting members 36 are provided at the ends of the third scaffolding 3C in the X direction. The connecting members 36 are arranged to extend along the vertical direction Z. In this embodiment, the connecting members 36 are configured to extend further downward Z2 from the connection part with the scaffolding main body part 30. The connecting members 36 are provided at each of two locations in the Y direction, and the support parts 35 and the scaffolding main body part 30 are connected by the connecting members 36 at two locations in the Y direction.

[0080] When the third scaffolding 3C is attached to a pair of storage shelves 1, the connecting member 36 is configured to face at least the shelf 10 to which the support parts 35 are attached from the inside in the X direction (the second side X2 in the X direction in FIG. 14 ). In this embodiment, facing the shelf 10 means facing the rail 2 provided on the shelf 10. Although the connecting member 36 can be configured to face only the shelf 10 to which the support parts 35 are attached from the inside in the X direction, in this embodiment, the connecting member 36 is configured to face not only the shelf 10 to which the support parts 35 are attached, but also the shelf 10 one level below this shelf part 10 from the inside in the X direction. In other words, the connecting member 36 is configured to face both of the two shelf parts 10 adjacent to each other in the vertical direction Z from the inside in the X direction.

[0081] Movement of the third scaffolding 3C toward the first side X1 in the X direction is restricted by a connecting member 36 provided at the end of the third scaffolding 3C on the first side X1 in the X direction, and movement of the third scaffolding 3C toward the second side X2 in the X direction is restricted by a connecting member 36 provided at the end of the third scaffolding 3C on the second side X2 in the X direction. As described above, in this embodiment, the X-direction restricting structure 4X is provided with connecting members 36 that face the shelf portions 10 (specifically, the rails 2) of each of the pair of storage shelves 1 from the inside in the X direction. In order to ensure high stability of the third scaffolding 3C when attached to the pair of storage shelves, it is preferable that the connecting members 36 face the shelf portions 10 without any gap (i.e., come into contact with them) when the third scaffolding 3C is attached to the pair of storage shelves 1.

[0082] In this embodiment, the scaffolding main body 30 is configured to be detachable from the connecting member 36. Specifically, as shown in FIG. 14 , the third scaffolding 3C includes a holding portion 37 that holds the scaffolding main body 30, and the connecting member 36 connects the support portion 35 and the scaffolding main body 30 via the holding portion 37. Although not shown, the holding portion 37 is provided with a mounting portion on which the scaffolding main body 30 is placed. The connecting member 36 is fixed to each of the support portion 35 and the holding portion 37, thereby connecting the support portion 35 and the holding portion 37. Then, with a unit including the support portion 35, the connecting member 36 (here, a pair of connecting members 36), and the holding portion 37 attached to each of the pair of storage shelves 1, the scaffolding main body 30 is attached so as to be placed on the holding portion 37 from the upper side Z1. Furthermore, the scaffolding main body 30 is detached from the holding portion 37 by moving the scaffolding main body 30 to the upper side Z1.

[0083] When the scaffolding main body 30 is not attached to the holding parts 37, movement of the unit toward the inside in the X direction (the second X-direction side X2 in FIG. 14 ) is restricted by the first opposing part 41 and the second opposing part 42 that are arranged to face the rail 2 from the outside in the X direction. This restriction is performed by the support parts 35, so the lower part of the connecting member 36 that is provided to extend from the support part 35 to the lower side Z2 can be displaced toward the inside in the X direction, but when the scaffolding main body 30 is attached to the holding parts 37, the scaffolding main body 30 is braced between the holding parts 37 on both sides in the X direction, so that the displacement of the connecting member 36 toward the inside in the X direction can be restricted.

[0084] 14 , when the scaffolding main body part 30 is attached to the holding parts 37, movement of the scaffolding main body part 30 in the Y direction is restricted by the connecting members 36 arranged on both sides of the scaffolding main body part 30 in the Y direction. Furthermore, when the scaffolding main body part 30 is attached to the holding parts 37, movement of the scaffolding main body part 30 in the X direction is restricted by the holding parts 37 arranged on both sides of the scaffolding main body part 30 in the X direction.

[0085] Other Embodiments (1) In the above embodiments, an example has been described in which the additional scaffolding 8 is supported from the lower side Z2 by a pair of storage shelves 1 on the first side Y1 in the Y direction, and is supported from the lower side Z2 by the scaffolding 3 on the second side Y2 in the Y direction. However, the present disclosure is not limited to such a configuration, and the additional scaffolding 8 can also be configured to be supported from the lower side Z2 by a pair of storage shelves 1 (specifically, a pair of rails 2) on both sides in the Y direction, similar to the scaffolding 3. Even in this case, the fitted portion 82 fits into the fitting recess 33, thereby restricting movement of the additional scaffolding 8 in the Y direction.

[0086] (2) In each of the above embodiments, the article storage facility 100 is described as having an additional scaffolding 8 as an example. However, the present disclosure is not limited to such a configuration, and the article storage facility 100 may also be configured without having an additional scaffolding 8. In this case, the connecting portion 32 does not need to be provided on the scaffolding 3. For example, the fourth restricting member 74 in the above first and second embodiments may be a plate-shaped member perpendicular to the Y direction, similar to the third restricting member 73. Even if the article storage facility 100 does not have an additional scaffolding 8, by arranging multiple scaffoldings 3 (e.g., two scaffoldings 3) adjacent to each other in the Y direction, it is possible to ensure a larger width of the tread in the Y direction compared to when a single scaffolding 3 is used. The position of the scaffolding 3 in the Y direction can be adjusted by adjusting the position of the first opposing portion 41 and the second opposing portion 42 in the Y direction. Therefore, even when multiple scaffoldings 3 are arranged adjacent to each other in the Y direction, it is possible to minimize the gap between two adjacent scaffoldings 3 in the Y direction.

[0087] (3) In the above embodiments, the Y-direction restricting structure 4Y is described as including a gap adjustment mechanism 5 that adjusts the gap in the Y direction between the first opposing portion 41 and the second opposing portion 42. However, the present disclosure is not limited to such a configuration, and the Y-direction restricting structure 4Y may be configured not to include a gap adjustment mechanism 5.

[0088] (4) In each of the above embodiments, the configuration has been described as an example in which the member (support surface forming member) that forms the support surface for the item A on the shelf section 10 is the aligning member 11. However, the present disclosure is not limited to such a configuration, and any member other than the support surface forming member can be the aligning member 11 as long as it is a member that is arranged in multiple in the Y direction on the storage shelf 1. For example, the aligning member 11 can be a pillar member that the storage shelf 1 has, or a bolt that connects members on the storage shelf 1, etc.

[0089] (5) In the above embodiments, an example has been described in which the scaffolding 3 is arranged to bridge the X-direction gap between a pair of storage shelves 1 and is supported from the lower side Z2 by the rails 2 of each of the pair of storage shelves 1. However, the present disclosure is not limited to such a configuration, and the scaffolding 3 may also be arranged to bridge the X-direction gap between a pair of storage shelves 1 and be supported from the lower side Z2 by members other than the rails 2 of each of the pair of storage shelves 1 (for example, horizontal members 15 provided instead of the rails 2).

[0090] (6) Note that the configurations disclosed in the above-described embodiments can be applied in combination with configurations disclosed in other embodiments (including combinations of embodiments described as 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.

[0091] [Summary of this embodiment] The above-described embodiments of the item storage facility will be summarized below.

[0092] The article storage facility is an article storage facility comprising a pair of storage shelves arranged to face each other, and a scaffolding configured to be detachable from the pair of storage shelves, wherein the direction in which the pair of storage shelves face each other is defined as an X direction, a direction perpendicular to the X direction when viewed in a vertical direction is defined as a Y direction, one side in the Y direction is defined as a Y direction first side, and the other side in the Y direction is defined as a Y direction second side, the pair of storage shelves are arranged to be spaced apart in the X direction, each of the pair of storage shelves is provided with a plurality of alignment members aligned in the Y direction, and the scaffolding is configured to be detachable from the pair of storage shelves in the X direction. The scaffolding is provided with a locking structure that is locked to each of the pair of storage shelves while being arranged so as to span between them, and the locking structure is provided with a Y-direction regulating structure that regulates movement of the scaffolding in the Y direction, and the Y-direction regulating structure is provided with a first opposing portion that faces a first alignment member, which is one of the alignment members in each of the pair of storage shelves, from a first side in the Y direction, and a second opposing portion that faces the first alignment member or a second alignment member, which is another alignment member than the first alignment member, in each of the pair of storage shelves, from a second side in the Y direction.

[0093] According to this configuration, when the scaffolding is arranged to span the X-direction between a pair of storage shelves, movement of the scaffolding toward the first side in the Y direction is restricted by the second opposing portion that faces the alignment member from the second side in the Y direction, and movement of the scaffolding toward the second side in the Y direction is restricted by the first opposing portion that faces the alignment member from the first side in the Y direction. In this way, according to this configuration, movement of the scaffolding toward both sides in the Y direction when attached to a pair of storage shelves can be restricted by the contact between the members rather than by friction between the members. Therefore, it is easy to increase the stability of the scaffolding when attached to a pair of storage shelves.

[0094] Here, it is preferable that the Y-direction regulating structure includes a gap adjusting mechanism that adjusts the gap in the Y direction between the first opposing portion and the second opposing portion.

[0095] According to this configuration, even when the Y-direction spacing of the multiple alignment members varies depending on the location, or when the same scaffolding is installed on storage shelves with different Y-direction spacing of the multiple alignment members, the spacing between the first opposing portion and the second opposing portion can be adjusted to match the Y-direction spacing of each alignment member. Therefore, it is easy to increase the versatility of the scaffolding.

[0096] Preferably, the locking structure further includes an X-direction restricting structure that restricts movement of the platform in the X-direction.

[0097] This configuration makes it easier to further increase the stability of the scaffolding when attached to a pair of storage shelves.

[0098] The item storage facility further comprises an additional scaffolding arranged adjacent to the scaffolding on the first side in the Y direction, the scaffolding having a connecting portion arranged to protrude on the first side in the Y direction relative to a scaffolding main body portion forming a tread surface and connected to the additional scaffolding, the connecting portion having a fitting recess that is open on the upper side and recessed on the lower side and into which the additional scaffolding fits from above, the additional scaffolding having a connecting portion arranged adjacent to the scaffolding on the first side in the Y direction relative to a scaffolding main body portion forming a tread surface and a fitting recess that is formed to protrude on the first side in the Y direction relative to the additional scaffolding main body portion and a pair of supported protruding portions formed to protrude outward in the X direction from the side portion on the first side and supported from below by each of the pair of storage shelves, and a fitted portion provided on the side portion on the second side in the Y direction of the additional scaffolding main body portion and fitted into the fitting recess of the connecting portion, and it is preferable that the additional scaffolding is configured so that the side portion on the second side in the Y direction of the additional scaffolding main body portion is supported from below by the fitted portions being supported from below by the connecting portions.

[0099] According to this configuration, the movement of the additional scaffolding in the Y direction can be restricted by fitting the fitted portion of the additional scaffolding into the fitting recess of the scaffolding, whose movement in both directions in the Y direction is restricted. Therefore, the need to provide the additional scaffolding with a structure that restricts movement in the Y direction can be reduced. Furthermore, according to this configuration, the additional scaffolding is supported from below by a pair of storage shelves on the first side in the Y direction, while it is supported from below by the scaffolding on the second side in the Y direction. Therefore, the additional scaffolding cannot be properly installed unless it is used together with the scaffolding, and it is easy to prevent the additional scaffolding from being accidentally used alone. Note that if the additional scaffolding does not have a structure that restricts movement in the Y direction, the additional scaffolding is more likely to move in the Y direction than if it were not provided, and there is a greater need to prevent the additional scaffolding from being accidentally used alone. Therefore, this configuration is particularly suitable for cases where the additional scaffolding does not have a structure that restricts movement in the Y direction.

[0100] In the configuration in which the item storage equipment is equipped with the additional scaffolding as described above, it is preferable that the connecting portion is arranged to extend toward the first side in the Y direction relative to the mating recess and is equipped with a guide portion that is inclined upward as it approaches the first side in the Y direction.

[0101] According to this configuration, when the fitted portion of the additional scaffolding is fitted into the fitting recess of the connecting portion, the fitted portion is guided toward the fitting recess along the guide portion, making it easier to install the additional scaffolding. Furthermore, according to this configuration, when the fitted portion is not fitted into the fitting recess, the side portion of the additional scaffolding on the second Y-direction where the fitted portion is provided is positioned above the appropriate position. Therefore, it is easy to visually determine whether the additional scaffolding is installed properly.

[0102] In the item storage equipment of each of the above configurations, each of the pair of storage shelves has multiple shelf sections arranged in the vertical direction, and the scaffolding has a support section having the locking structure, a scaffolding main section arranged below the support section to form a tread surface, and a connecting member that connects the support section and the scaffolding main section in the vertical direction, and it is preferable that the vertical distance between the support section and the scaffolding main section is smaller than the vertical distance between two vertically adjacent shelf sections in each of the pair of storage shelves.

[0103] According to this configuration, when scaffolding is installed on each of the shelves at different heights in the vertical direction on a storage shelf to form a stepped tread, even if the vertical distance between two vertically adjacent shelves on the storage shelf is too wide, by using scaffolding of this configuration, the scaffold main body can be positioned at the height between the two vertically adjacent shelves. Therefore, by using scaffolding of this configuration in combination with scaffolding whose scaffold main body is positioned at the same height as the shelves, stepped treads positioned at an appropriate vertical distance can be formed.

[0104] In the above-described configuration in which the scaffolding comprises the support portion, the scaffolding main body portion, and the connecting member, it is preferable that the connecting member is configured to face both of the two shelf portions adjacent in the vertical direction from the inside in the X direction.

[0105] With this configuration, the outward movement of the connecting member in the X direction can be restricted by the two shelves located at different heights in the vertical direction, thereby enabling stable support of the scaffolding main body located below the support part.

[0106] In each of the above-described configurations of item storage facilities, it is preferable that the item storage facilities further include a transfer machine that travels along the Y direction and transfers items between the storage shelves, each of the pair of storage shelves having rails arranged to extend along the Y direction and on which the transfer machine travels, and that the scaffolding is arranged to span the space between the pair of storage shelves in the X direction and is supported from below by the rails on each of the pair of storage shelves.

[0107] According to this configuration, a scaffold can be installed to span the X-direction between the pair of storage shelves by utilizing rails provided on each of the pair of storage shelves for travel of the transfer machine. This reduces the need for dedicated members for installing the scaffold, thereby reducing costs.

[0108] It is sufficient for the article storage facility according to the present disclosure to achieve at least one of the above-mentioned effects. [Explanation of symbols]
