Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a circulation type storage, and more specifically, it is possible to place heavy objects on the storage shelf, and it is possible to place items in and out of storage shelves. This invention relates to a circulation type storage that can be accessed from the side of the storage.

[Prior Art] The most typical example of a circulating shelf holding plywood horizontally is a multi-story parking lot, but in this multi-story parking lot,
The plywood on which the car body is placed is attached to a chain that passes through the sprockets placed above and below, and when the chain that connects the plywood meshes with the sprocket and the base plate circulates, the chain bends at the bend of the chain. The pulsation of the chain causes the plywood to swing significantly, and even if the chain is running at a slow speed, the larger the pitch of the chain, the greater the swing.
There was a tendency for the noise caused by the hammering sound produced when the chain and sprocket engaged to become louder, and there was also significant oscillation due to inertia at the start and stop of movement.

In order to solve the above-mentioned difficulties,
Even the merry-go-round type rotating storage device proposed in the publication cannot be said to have solved the problems of pulsation, rocking, and noise.

[Problem that the invention seeks to solve]

As mentioned above, with conventional circulating type movable shelves, strictly speaking, the movable shelf cannot be kept horizontal due to the effects of chain pulsation and inertia during startup and stop, and it oscillates with vibrations caused by chain pulsation. In addition, there remains the problem of moments generated by uneven loads of articles placed on the shelves.

Therefore, in order to solve the above-mentioned problems and drawbacks, the present inventor provided an endless first chain and a second chain on both the left and right sides of the device so as to be able to circulate. We have proposed a system in which a large number of storage shelves are attached to the chain and the second chain via links, and each storage shelf is transported while maintaining parallelism during circulation.
Since the storage shelf circulates from the front to the rear of this product, it is necessary to have a wide depth when installing it, so we further improved this so that the shelf can be made cantilevered so that loaded items can be taken in and out from the left and right sides of the shelf. Although this cantilever circulation shelf can reduce the installation area, it has the problem that it is difficult to store heavy items because the shelf is supported on a cantilever. .

SUMMARY OF THE INVENTION An object of the present invention is to provide a recirculating shelf that allows loaded items to be taken in and taken out from the side, thereby reducing the installation area, and in addition, making it possible to load heavy items. be.

[Means for solving problems]
