JP 2011-136791 A

In an automated warehouse, when the beam members of racks and the rails on which carts run are also used, the vibrations generated from the carts are transmitted directly to the shelves via the rails, causing the goods placed on the shelves to vibrate. There is a possibility that position deviation, rotation, etc. may occur. When a load shift occurs, even if the trolley is stopped at an accurate position, the load may not be automatically transferred. Also, by limiting the running speed of the trolley, it is possible to prevent the load from being displaced.

SUMMARY OF THE INVENTION It is an object of the present invention to provide an automated warehouse capable of achieving both high-speed travel of the truck and stability of the cargo held on the rack, even if the rack is equipped with rails on which the truck travels. and

FIG. 1 is a perspective view showing an automated warehouse provided with racks and transport devices. As shown in the figure, the automated warehouse 200 automatically transfers packages 300 to the racks 201 using the carrier device 100, and unloads the packages 300 held on the racks 201 using the carrier device 100. It is a system that can

In the present embodiment, the traveling direction (X-axis direction) in which the conveying device 100 (carriage 101) travels, and the direction perpendicular to the traveling direction in the horizontal plane as the depth direction (Y-axis direction). A direction and a direction orthogonal to the depth direction may be referred to as an up-down direction (Z-axis direction).

The rack 201 is equipment for holding the cargo 300 and includes a first support 211 , a second support 212 , a first mounting bracket 220 , a beam member 213 and a holding member 214 .

The first support 211 and the second support 212 are columnar structural members that support the beam member 213 , the holding member 214 and the rail 162 and extend vertically. The first struts 211 are struts arranged side by side along the running direction of the truck 101 on the side on which the truck 101 travels, that is, the side on which the rails 162 are arranged. It is a pillar arranged side by side on the opposite side of the counter rail 162 . In the case of this embodiment, the first support 211 and the second support 212 are rectangular pipe-shaped, and the lower ends thereof are fixed to the floor or the like.

Note that the first support 211 and the second support 212 are names for distinguishing the support according to the position at which they are arranged, and they may have the same shape and size.

FIG. 2 is a perspective view showing the vicinity of the first mounting bracket. The first mounting bracket 220 is attached to the first support 211 and is a member for attaching the beam member 213 to the first support 211 . The shape of the first mounting bracket 220 is not particularly limited. , two connecting portions 222 extending from both ends of the base portion 221 in the extending direction of the beam member 213 (the X-axis direction in the drawing) toward the second support column 212, and and two fixing portions 223 extending from the ends toward the adjacent first struts 211 respectively. In addition, only the base portion 221 of the first mounting bracket 220 is in contact with the first support 211 , and the connection portion 222 and the fixing portion 223 are not in contact with the first support 211 . As a result, the vibration transmitted to the first strut 211 is weakened, and the vibration transmitted to the beam member 213 is suppressed.

Although the manufacturing method of the first mounting bracket 220 is not particularly limited, in the case of the present embodiment, the first mounting bracket 220 is formed by bending a sheet metal. Thereby, it is possible to provide structural strength capable of supporting the beam member 213, the holding member 214, and the load held by the holding member 214, and to effectively suppress the propagation of vibration.

As for the first mounting bracket 220 attached to the first strut 211 arranged at the end, one connecting portion 222 and one fixing portion 223 may be attached to the base portion 221 .

The beam member 213 is a rod-shaped member extending in the horizontal direction, and is a member attached to the first mounting brackets 220 attached to the adjacent first supports 211 in a bridge manner.

The beam member 213 is attached to the rail 162 side surface of the fixing portion 223 of the first mounting bracket 220 attached to the first support column 211, and the beam member 213 is attached to the rail 162 at least to the extent that it does not come into contact with the beam member 213 even if the rail 162 vibrates. are placed at intervals of In plan view, the distance between the beam member 213 and the rail 162 is set by the length of the beam member 213 in the depth direction (the length in the Y-axis direction in the figure) and the length of the connection portion 222 of the first mounting bracket 220. can do.

Also, both ends of the beam member 213 are arranged in a state separated by a predetermined distance without coming into contact with the connecting portion 222 of the first mounting bracket 220 . As a result, the beam member 213 does not receive vibration directly from the connection portion 222 of the first mounting bracket 220, and the beam member 213 can be stabilized even if the rail 162 vibrates.

Further, in the case of the present embodiment, a damping member 230 is sandwiched between the fixing portion 223 of the first mounting bracket 220 and the beam member 213 . Vibration damping member 230 is not particularly limited as long as it is a member that absorbs vibration transmitted to first mounting bracket 220, but in the case of the present embodiment, it is a damper made of a viscoelastic body. According to this, it is possible to attenuate the vibration generated in the rail 162 when the truck 101 travels, the vibration due to an earthquake, and the like, and it is possible to suppress the vibration propagated to the beam member 213 .

The holding member 214 is a member for holding the cargo 300, and the end edge on the rail 162 side, which is one end in the depth direction, is attached to the first support 211 via the beam member 213 and the first mounting bracket 220, The other end is a member attached to the second support. The shape and structure of the holding member 214 are not particularly limited. It is a member that is fitted and attached to the member 213 . A third mounting bracket is attached to the second support 212, the beam member 213 is also attached to the second support 212 via the third mounting bracket, and the holding members 214 are arranged side by side in the depth direction. It is attached to the two beam members 213 that are connected in the form of a bridge. Since the holding member 214 is in contact only with the beam member 213 and attached to the support via the beam member 213, the first mounting bracket 220, and the third mounting bracket, the vibration applied to the support is damped. It propagates to the holding member 214 in a state. As a result, the load 300 placed on the holding member 214 is held in a stable state without displacement or rotation even when the carriage 101 travels at high speed on the rail 162 attached to the first support 211. be done. The shape of the first mounting bracket 220 and the shape of the third mounting bracket may be the same or different.

The rail 162 is a long rod-shaped member for forming a track on which the carriage 101 of the transfer device 100 travels, and is attached to the side surface of the first support 211 . In the case of this embodiment, the automated warehouse 200 is a warehouse in which the transport device 100 travels between two racks 201 arranged in parallel. there is The conveying device 100 travels across two rails 162 arranged in the same horizontal plane.

The carriage 101 is a structural base member of the transport device 100 . The structure of the trolley 101 is not particularly limited, and in the case of the present embodiment, the trolley 101 has a structure in which rod-like members having the same structure as the column members 110 are combined in a ladder shape, parallel grid shape, or the like.

In the case of the present embodiment, a traveling device 160 is attached to the carriage 101 so that the transport device 100 as a whole can travel along rails 162 . As a result, the conveying device 100 functions as a stacker crane, and can convey the load 300 in the vertical direction and the running direction (the X-axis direction in the drawing). For example, the travel device 160 includes wheels 161 and a travel drive source 163 , and the power of the travel drive source 163 rotates the wheels 161 on rails 162 to cause the conveying device 100 to travel.

The column member 110 is a columnar member that extends upward from the carriage 101 and functions as a column that supports the lift table 130 that is stopped or being lifted. If there are at least two pillar members 110 , it is possible to support the lift table 130 . The four pillar members 110 stand vertically upward from the four corners of the carriage 101 assembled in a rectangular shape.

The pulley 121 is a member called a sheave, a pulley, or the like arranged in the upper end region of the column member 110 . By arranging the pulleys 121 at positions corresponding to both ends of the lifting platform 130 , the lifting platform 130 can be raised and lowered via the pulleys 121 .

The hanging member 122 is a long flexible member such as a wire, chain, or belt that is hung on the pulley 121 . In the case of this embodiment, the hanging member 122 is a timing belt connected in a loop, and is stretched in an endless track state between a lifting device 120 having a motor attached to the carriage 101 and the pulley 121. . Suspension members 122 respectively hung on two pulleys 121 are suspended on one elevating device 120 , and the operation of the elevating device 120 interlocks the two suspension members 122 . The lifting device 120 includes a lifting drive source 123 such as a motor, a second pulley 124 on which the hanging member 122 is hung, and a shaft 125 connecting the two second pulleys 124 .

The lifting platform 130 is a member that is connected to the suspension member 122 at separate connection points 131 and holds the load 300 between the connection points 131 . In other words, the lifting platform 130 is lifted and lowered by the lifting device 120 via the hanging member 122 to convey the held load 300 in the vertical direction.

The frame 140 is a member attached to the main body of the lifting table 130 in a state of protruding upward from the mounting surface of the lifting table 130, and is a member for stably moving the lifting table 130 up and down with respect to the column member 110. be.

In the case of this embodiment, guide rollers 104 are rotatably attached to each frame 140 and roll in contact with the column member 110 .

The transfer device 170 is a device for transferring the load 300 between the rack 201 and the lift table 130 and is attached to the lift table 130 . The transfer method of the load 300 of the transfer device 170 is not particularly limited. As the transfer device 170 , there is a device that pushes out and pulls in the load 300 by applying a claw to the back side of the load 300 in the transfer direction, and a device that moves the load 300 between the rack 201 and the lift table 130 while holding the side of the load 300 . For example, the load 300 placed on the pallet is lifted by a fork and transferred.

According to the automated warehouse 200 according to the above embodiment, even when the relatively tall transport device 100 is run at high speed on the rail 162 attached to the first support 211 of the rack 201, This vibration is sufficiently attenuated before it reaches the holding member 214, thereby preventing the load 300 placed on the holding member 214 from slipping. Therefore, transfer errors of the transfer device 170 are reduced, and the efficiency of conveying the cargo 300 can be improved.

Moreover, since the rail 162 is attached to the first support 211 of the rack 201, the traveling route of the transport device 100 and the rack 201 can be brought closer, and the entire automated warehouse 200 can be made compact. On the other hand, since the beam members 213 that support the holding members 214 do not directly contact the rails 162 at a predetermined interval, the dead space can be suppressed and vibrations generated in the rails 162 are less likely to be transmitted to the holding members 214 .

It should be noted that the present invention is not limited to the above embodiments. For example, another embodiment realized by arbitrarily combining the constituent elements described in this specification or omitting some of the constituent elements may be an embodiment of the present invention. The present invention also includes modifications obtained by making various modifications to the above-described embodiment within the scope of the gist of the present invention, that is, the meaning of the words described in the claims, which a person skilled in the art can think of. be

For example, in the above-described embodiment, the rail 162 is attached to the first support 211 via the first mounting bracket 220 , but the rail 162 may be attached directly to the first support 211 .

In addition, although the automated warehouse 200 provided with the conveying device 100 capable of raising and lowering the cargo 300 has been illustrated, an automated warehouse 200 in which a plurality of conveying devices 100 without a lifting device are arranged in stages corresponding to the respective stages of the holding members 214 It may be the warehouse 200 as well. That is, a rail 162 is attached to each stage, and the conveying device 100 travels on each rail 162 .

Moreover, although the conveying apparatus 100 that can lift and lower the load 300 over the three stages of the holding members 214 of the rack 201 has been illustrated, the lifting stroke of the load 300 is not limited.
