In such a rack, the load may be loaded and unloaded in a state where the load is placed on a mounting plate constituting the shelf, that is, by sliding the load without lifting the load. In racks where loading and unloading is performed in this way, the loads are arranged at intervals so that they do not come into contact with adjacent loads when loading and unloading, and the loads are arranged so as not to interfere with loading and unloading. In many cases, no member is placed to regulate the movement of the. Therefore, due to the behavior of the load caused by the traveling of the transport device or the vibration caused by the occurrence of an earthquake, the position of the load may shift, the load may rotate, or the load may fall from the shelf.

Therefore, an object of the present invention is to provide a rack of an automated warehouse capable of suppressing the behavior of a load caused by vibration caused by traveling of a transport device or the occurrence of an earthquake.

The rack of the automatic warehouse of the present invention is a rack of an automatic warehouse in which loads are transferred by the transfer device of the transfer device, and is arranged at a position facing the traveling path of the transfer device and extends in the vertical direction. Along the travel path at a position farther from the travel path than the first column in the transfer direction in which the transfer device loads and unloads the load in the direction intersecting the traveling direction and the vertical direction of the one column and the transport device. A second strut that is arranged in the vertical direction and is provided between the arrangement position and the second arrangement position of the first strut, and a mounting plate on which the load is placed and a mounting plate in the transfer direction. It is provided with a guide member that movably supports the mounting plate and a regulating member that regulates the movement of the mounting plate in the transfer direction between the arrangement position of the first support column and the arrangement position of the second support column.

In an automated warehouse rack having this configuration, a mounting plate having a first guide surface and a second guide surface can be formed by a simple process such as bending process.

In the rack of the automatic warehouse of the present invention, the lower surface of the mounting plate opposite to the upper surface on which the load is placed and the upper surface of the second beam member intersecting in the vertical direction are in direct or indirect contact with each other. The mounting plate and the second beam are arranged in a state so that the frictional force generated between the mounting plate and the second beam member is smaller than the frictional force generated between the mounting plate and the load. At least one of the members may be configured. In the rack of the automated warehouse having this configuration, the frictional force generated between the mounting plate and the load and the frictional force generated between the mounting plate and the second beam member are made different from each other with respect to the mounting plate. This makes it possible to make the mounting plate slippery with respect to the second beam member while making the load less slippery. As a result, the behavior of the load caused by the vibration caused by the traveling of the transport device or the occurrence of an earthquake can be suppressed more reliably.

In the rack of the automatic warehouse of the present invention, an anti-slip member is arranged on the upper surface on which the load is placed on the mounting plate, and the lower surface on the side opposite to the upper surface on which the load is placed on the mounting plate and the second The upper surfaces of the beam members that intersect in the vertical direction are arranged in direct or indirect contact with each other, and the frictional force generated between the mounting plate and the second beam member is generated between the anti-slip member and the load.

Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the drawings. In the description of the drawings, the same elements are designated by the same reference numerals, and duplicate description will be omitted. The terms "above" and "below" correspond vertically upwards and downwards.

The rack 10 of the present embodiment shown in FIGS. 1 and 2 is used for an automated warehouse 1 that automatically stores the loaded load L and automatically carries out the stored load L. Here, first, the outline of the automated warehouse 1 will be described. The automated warehouse 1 includes a rack 10 and a stacker crane (conveyor device) 50. In the figure, the "Z direction" is the vertical direction and is the step direction of the rack 10. The "X direction" is a horizontal direction and is a traveling direction of the stacker crane 50. The "Y direction" is a horizontal direction perpendicular to the X direction and the Z direction, and is a transfer direction of the load L of the stacker crane 50 described later.

The rack 10 stores the load L in a matrix in the X direction and the Z direction. The rack 10 here is a so-called flat shelf, and has a plurality of shelf portions 10A. The shelf portion 10A includes a plurality of columns 11, a plurality of first beam members (regulatory members) 13, a plurality of second beam members (guide members) 15, and a mounting plate 20. The details of the rack 10 will be described later.

The stacker crane 50 is a device for loading and unloading a load L with respect to the shelf portion 10A of the rack 10. The stacker crane 50 travels between the pair of racks 10 along the X direction. In other words, the racks 10 are arranged on both sides of the stacker crane 50. The stacker crane 50 includes a traveling portion 51, a mast 52, an elevating platform 53, and a transfer device 54.

The traveling portion 51 is configured to be freely travelable along a traveling rail 56 extending along the X direction between the pair of racks 10. The traveling unit 51 includes driving wheels, a traveling motor, and the like. The mast 52 is erected on the traveling portion 51 along the Z direction. The lift 53 is configured to be able to move up and down along the mast 52. The transfer device 54 is provided on the elevating table 53. The transfer device 54 transfers the load L to and from the shelf 10A in a state where the elevating table 53 is stopped at the elevating stop position. An example of a mechanism for transferring a load L such as a tray to the rack 10 in the transfer device 54 is a rear hook mechanism for transferring by hooking a hook at the rear end of the load L as shown in FIG. In addition, a clamp mechanism for transferring while sandwiching and holding both sides of the load L, and a front hook for transferring by hooking a hook on the front end of the load L are included.

Next, the rack 10 having the shelf portion 10A in which the load L is taken in and out by the stacker crane 50 will be described in detail. As shown in FIGS. 1 and 2, the rack 10 includes a first support column 11A, a second support column 11B, first beam members 13A and 13B, a second beam member 15, and a mounting plate 20. I have. For convenience of explanation, the mounting plate 20 is not shown in FIG.

The first column 11A is arranged along the traveling rail 56 at a position facing the traveling path of the stacker crane 50, and extends in the vertical direction. The second support column 11B is a direction orthogonal to (intersects) the traveling direction (X direction) and the vertical direction (Z direction) of the stacker crane 50, and is a transfer direction (Y direction) in which the stacker crane 50 loads and unloads the load L. ), It is arranged along the traveling rail 56 at a position farther from the traveling path (traveling rail 56) than the first support column 11A, and extends in the vertical direction.

The first beam member 13A is a beam member that extends in the X direction and connects the first columns 11A and 11A to each other. The first beam member 13A is arranged along the traveling rail 56 at a position facing the traveling path of the stacker crane 50. Like the first beam member 13A, the first beam member 13B is also a beam member that extends in the X direction and connects the second columns 11B and 11B to each other. The first beam member 13B is arranged along the traveling rail 56 at a position farther from the traveling path (traveling rail 56) than the first beam member 13A in the transfer direction (Y direction).

The second beam member 15 is bridged over the first beam member 13A and the first beam member 13B (a pair of first beam members) and is arranged in the X direction. As shown in FIGS. 3A and 3B, the second beam member 15 has an upper surface 15a orthogonal to the Z direction, side surfaces 15b and 15b orthogonal to the X direction, and a lower portion located at the lower end in the Z direction. It has 15c and 15c. The second beam member 15 movably supports the mounting plate 20 on which the load L is placed between the first beam member 13A and the first beam member 13B in the Y direction. Specifically, the upper surface 15a of the second beam member 15 is supported in contact with the lower surface 21a on the side opposite to the upper surface 21b on which the load L is placed on the mounting plate 20, and the load L is placed on the mounting plate 20. The mounting plate 20 in the mounted state is formed or processed so as to be slidable (movable).

The mounting plate 20 is provided between the arrangement position of the first support column 11A and the arrangement position of the second support column 11B, and the load L is placed on the mounting plate 20. As described above, the mounting plate 20 is supported so as to be movable in the Y direction with respect to the second beam member 15. The mounting plate 20 has a mounting surface 21 having a lower surface 21a that is contact-supported by the upper surface 15a of the second beam member 15 and an upper surface 21b that is a surface on which the load L is mounted, and a side surface 15b of the second beam member 15. The pair of first guide surfaces 23, 23, which are arranged to face each other and restrict the movement of the mounting plate 20 in the X direction, and the lower portions 15c, 15c of the second beam member 15 are arranged to face each other. It has a pair of second guide surfaces 25, 25 that regulate the lifting (movement in the vertical direction) of the mounting plate 20 in the Z direction. In the mounting plate 20 of the present embodiment, the mounting surface 21, the pair of first guide surfaces 23, 23, and the pair of second guide surfaces 25, 25 are formed of one plate-shaped member.

An anti-slip member 31 is arranged on the upper surface 21b of the mounting surface 21 of the mounting plate 20. The anti-slip member 31 is a member that makes the frictional force generated between the mounting plate 20 and the second beam member 15 smaller than the frictional force generated between the anti-slip member 31 and the load L. In other words, the anti-slip member 31 is a member that adjusts the frictional force between the anti-slip member 31 and the load L mounted on the mounting plate 20, and for example, the load L is taken in and out while being slid on the anti-slip member 31 by the stacker crane 50. A member having a friction coefficient that does not hinder the operation is used. An example of the anti-slip member 31 is a non-slip sheet.

The first beam member 13A and the first beam member 13B restrict the movement of the mounting plate 20 movably supported in the transfer direction along the second beam member 15 in the transfer direction. The first beam member 13A and the first beam member 13B restrict the movement of the mounting plate 20 in the transfer direction between the arrangement position of the first support column 11A and the arrangement position of the second support column 11B. The first beam member 13A and the first beam member 13B project upward from the upper surface of the second beam member 15 on which the mounting plate 20 is mounted, and downward from the lower portion 15c of the second beam member 15. .. The second beam member 15 is fixed to the side surfaces 14b and 14b orthogonal to the Y direction in the first beam member 13A and the first beam member 13B by welding or the like. Further, the upper surfaces 14a and 14a of the first beam member 13A and the first beam member 13B orthogonal to the Z direction and the surface 31a of the anti-slip member 31 arranged on the mounting plate 20 are flush with each other (Z direction). Are arranged on the same plane).

In the rack 10 of the automated warehouse of the above embodiment, since the mounting plate 20 on which the load L is placed is configured to be movable in the Y direction, it becomes difficult for the vibration generated by the traveling of the stacker crane 50 to be transmitted to the load. .. Further, since the mounting plate 20 on which the load L is mounted is configured to be movable in the Y direction, it becomes difficult for the vibration generated by the occurrence of an earthquake to be transmitted to the load L. As a result, the behavior of the load L due to the vibration generated by the traveling of the stacker crane 50 or the occurrence of an earthquake can be suppressed. As a result, the position of the load L shifts or the load L rotates, so that, for example, the transfer device 54 having the rear hook mechanism cannot hook the hook on the load L. It is possible to avoid the trouble of. Further, due to the behavior of the load L described above, it is possible to prevent the load L from falling from the shelf portion 10A. When the rack 10 has seismic performance, the acceleration applied to the load L at the time of an earthquake becomes large, and the behavior of the load L also becomes large. Therefore, the effect is great when the present invention is applied to the rack 10 having seismic performance.

In the rack 10 of the above embodiment, as shown in FIG. 2, the first beam members 13A and 13B arranged in the normal rack 10 are used as the regulating members for restricting the movement of the mounting plate 20 in the Y direction. Therefore, a simple configuration can be achieved without separately arranging other members.

In the rack 10 of the above embodiment, the second beam member 15 arranged in the normal rack 10 can be used as a guide member for supporting the mounting plate 20, so that a simple configuration is made without separately arranging other members. Can be.

Since the mounting plate 20 of the rack 10 of the above embodiment has the first guide surface 23 arranged to face the side surface 15b of the second beam member 15, the mounting plate 20 has a simple configuration. Movement in the X direction can be restricted.

Since the first guide surfaces 23, 23 and the second guide surfaces 25, 25 of the mounting plate 20 of the above embodiment are formed of a single plate-shaped member, the first is a simple process such as bending. A mounting plate 20 having guide surfaces 23, 23 and second guide surfaces 25, 25 can be formed.

In the rack 10 of the above embodiment, the lower surface 21a of the mounting plate 20 and the upper surface 15a of the second beam member 15 are arranged in direct contact with each other, and the mounting plate 20 and the second beam member 15 are in direct contact with each other. The anti-slip member 31 is arranged on the upper surface 21b of the mounting plate 20 so that the frictional force generated between them is smaller than the frictional force generated between the mounting plate 20 and the load L. As a result, the frictional force generated between the anti-slip member 31 arranged on the mounting plate 20 and the load L and the frictional force generated between the mounting plate 20 and the second beam member 15 are made different from each other. The loading plate 20 can be made slippery with respect to the second beam member 15 while making the load L less slippery with respect to the mounting plate 20. As a result, the behavior of the load L caused by the vibration generated by the traveling of the stacker crane 50 or the occurrence of an earthquake can be suppressed more reliably.

Although one embodiment has been described above, the present invention is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the invention.

In the above embodiment, the mounting plate 20 is supported so as to be movable in the Y direction in a state of being in contact with the second beam member 15, but the present invention is not limited thereto. For example, as shown in FIG. 4, a flat plate 115 may be provided instead of the second beam member 15 of the above embodiment. Further, the flat plate 115 may support the flat plate-shaped mounting plate 120 which is arranged via a roller 35 which can move only in the Y direction instead of the mounting plate 20 described above. Further, the restricting members 113 and 113 for restricting the movement of the mounting plate 120 in the Y direction may be provided.

Even in the rack 110 of the automated warehouse having this configuration, since the mounting plate 120 on which the load L is placed is configured to be movable in the Y direction, it is difficult for the vibration generated by the traveling of the stacker crane 50 to be transmitted to the load L. Become. Further, in the rack 110 of the automated warehouse having this configuration, it becomes difficult for the vibration generated by the occurrence of an earthquake to be transmitted to the load L. In other words, even if acceleration acts on the rack 110 due to the occurrence of an earthquake or the like, the mounting plate 120 on which the load L is placed is configured to be movable in the Y direction, so that the acceleration acting on the load L is reduced. Will be done.

In the above embodiment or modification, the example in which the anti-slip member 31 is arranged on the upper surface 21b of the mounting surface 21 of the mounting plate 20 has been described, but the anti-slip member 31 may not be arranged. In this case, for example, by making the friction coefficient of the upper surface 21b of the mounting surface 21 larger than the friction coefficient of the lower surface 21a, the frictional force generated between the mounting plate 20 and the second beam member 15 is increased. It may be smaller than the frictional force generated between the mounting plate 20 and the load L.

In the above embodiment or modification, the lower surface 21a of the mounting surface 21 and the upper surface 15a of the second beam member 15 are in direct contact with each other, or the lower surface 121a of the mounting surface 21 and the upper surface 115a of the flat plate 115 are in direct contact with each other. Although the example of contacting through the roller 35 has been described, the frictional force generated between the anti-slip member 31 mounted on the mounting plate 20 and the load L is more than the frictional force generated on the lower surface 21a of the mounting plate 20. A sliding member may be interposed so that the frictional force generated between the second beam member 15 and the upper surface 15a is reduced. Further, the contact area between the upper surface 15a of the second beam member 15 and the lower surface 21a of the mounting plate 20 becomes smaller as necessary on at least one of the upper surface 15a of the second beam member 15 and the lower surface 21a of the mounting plate 20. Such surface treatment (for example, embossing for adjusting the frictional force or attachment of a member for adjusting the frictional force) is performed, and the frictional force generated between the mounting plate 20 and the second beam member 15 is reduced. It may be configured to be smaller than the frictional force generated between the mounting plate 20 (or the anti-slip member 31) and the load L.

In the above-described embodiment or modification, an example in which one load L is mounted on one mounting plate 20 has been described, but the present invention is not limited thereto. For example, two loads L may be mounted on one mounting plate 20, and a plurality of loads L may be mounted on one mounting plate 20. Even in this case, the behavior of the load caused by the vibration caused by the running of the stacker crane 50 or the occurrence of an earthquake can be suppressed.

In the above embodiment or modification, the mounting plate 20 is movable with respect to the second beam member 15 in contact with each other, or the mounting plate 120 is movable with respect to the flat plate 115 via the roller 35. Although the above examples have been described, for example, the mounting plate 120 may be provided so as to be movable with respect to the flat plate 115 constituting the shelf portion 10A via a linear motion mechanism.

In the above-described embodiment or modified example, one mounting plate 20 is arranged so as to straddle two second beam members 15 adjacent to each other. For example, one second beam member 15 has been described. One mounting plate 20 may be arranged on the two or more, or one mounting plate 20 may be arranged so as to straddle three or more second beam members 15 adjacent to each other.

The present invention is also applied to a transport device having a configuration different from that of the stacker crane described above. That is, according to the present invention, the transfer device can be moved horizontally along the track on the floor surface like the stacker crane described above, and the transfer device can be moved up and down along the mast. It can also be applied to a transport device having a configuration different from that of the transport device. For example, the present invention is a transfer device that can move the transfer device only in the vertical direction or the horizontal direction, or a transfer device that can move the transfer device in the horizontal direction along a track laid near the ceiling instead of on the floor surface. It can also be applied to devices (ceiling vehicles) and the like.
