Description

[Detailed description of the invention] Industrial application field The present invention is a rotary shelving system that is used to store and store long items or items made by combining multiple short items into a long item. It is related to.

Conventional technology Conventionally, as this type of technology, for example,
Like the storage device seen in Publication No. 52-43272,
Chain rings (sprockets) that can be rotated intermittently are arranged at intervals between the upper and lower parts, a chain is stretched between the chain rings, and buckets having a comb-like load supporting surface are attached at regular intervals to the chain. A large number of chains are suspended in the horizontal direction, and a means for fixing the chain is provided near the chain, and a transfer means is provided on one side of the chain for transferring the loads brought to the loading section by the loading roller conveyor to the bucket. There is something set up.

In order to store a load in this storage device, a motor is driven to place an arbitrary empty bucket in the loading section, and the chain is fixed so that it does not move by a means for positionally fixing the chain. Then, the load brought to the loading section by the loading roller conveyor is slid into the bucket by the transfer means. The loaded load is then stopped by a stopper formed on the load supporting surface of the bucket. Furthermore, the motor is operated intermittently to sequentially store loads into multiple buckets.

Problems that the invention aims to solve When storing loads on a bucket, this type of storage device positions and stores the loads in a fixed position to prevent them from losing their balance and falling, ensuring accurate and stable transportation. It is necessary to do so.

However, in the above-mentioned conventional storage device, the load supporting surface of the bucket is inclined and the load is slid into position for positioning, so it is difficult to position the load reliably, and there is a problem in the stability of transportation.

Moreover, when storing cargo, the cargo is directly loaded onto the bucket cart, which causes a strong impact on the bucket cart, causing the chain to swing, and requiring means for fixing the chain in position.

Furthermore, since the cargo must be stored while the chain is moved intermittently, continuous loading and unloading is not possible, which poses the problem of inefficiency.

This idea was made to solve these problems, and it not only makes it possible to position the load reliably, but also ensures accurate and stable transport of the load, and also prevents strong shocks from being applied to the bucket when loading the load into the bucket. To provide a rotary shelf facility that does not require a means for fixing the position of a chain, and further enables continuous loading and unloading of cargo.

Means for Solving the Problems In order to solve the above problems, the rotating shelving equipment of the present invention has a frame disposed between floors, and a pair of left and right endless rotating bodies are attached to the frame in the vertical direction. A plurality of bucket carts are installed between these endless rotating bodies so as to be able to swing relative to each other, and when the bucket carts face the loading section, the load supporting surface of the bucket trucks is connected to the horizontal member located on the loading loading section side. and a plurality of longitudinal members connected from this left-right member toward the loading section side to form a comb-like shape, forming a loading section on one of the upper and lower floors of the hierarchy. , forming the other cargo unloading section, and in the loading section, a plurality of receiving materials are provided that project in the direction of the loading section and are shifted in phase from the front and rear direction of the bucket to the left and right, so that the bucket can pass upwardly. A flexible tooth-shaped cargo receiver is installed,
A stopper surface that stands up on the inner end side of the load receiving device is formed, and guide plates are provided upright on both ends, and the load carrying device is provided with a comb-toothed carrying device attached to the frame body, through which the bucket can freely pass downward. It is arranged and configured both inside and outside.

According to the configuration of the present invention, the load pushed onto the load receiving device in the loading portion comes into contact with the stopper surface and the guide plates at both ends, and can always be positioned at a constant position. Then, the load supporting surface of the empty bucket that has risen passes upwardly against the load receiving device due to the comb structure.
This lifts the load. The load is conveyed upward to the upper floor, or immediately moves downward and conveyed downward to the lower floor, and is placed in a storage state during these conveyances.
Then, the bucket that reached the unloading section after being transported,
The comb structure allows it to pass downwardly relative to the removal device, thereby passing the load to the removal device.

8 is controlled via the link 27, and will not swing unexpectedly. On the first floor 2, a long load 46 is placed on a table 37 as shown by the solid line in FIG. The load 46 is then transferred to the receiving member 3 of the load receiving tool 32 by the operator as shown in the imaginary line in FIG.
Pushed above the 4th group. In this pushing, the load 46 is guided by the guide plate 36 and then hits the stopper surface 35, so that the load 46 is always positioned and stored in a fixed position. Further, pushing (carrying in) is performed when the operation is stopped, and this can be done by checking and operating the operating section 38. After that, when the operation is performed intermittently, the empty bucket 18 rises from the lower end of the ascending path 21, and the longitudinal material 25 passes upward between the receiving materials 34, which causes Load 4
6 is lifted by the bucket 18 via the load support surface 26.

Since the load 46 that is stationary on the load receiving device 32 is lifted by the bucket 18 in this way, the bucket 18
There is no strong impact when storing the load 46. Therefore, when loading a load, the chain 10 to which the bucket 18 is attached does not swing, and the load 4 is
The work of storing the 6 goes smoothly.

The load 46 ascends along the ascending route 21, passes through the second floor 4, and then reaches the third floor 6. Then, when moving to the descending route 22, the cargo unloading section 31 is immediately reached. In this cargo unloading section 31, the longitudinal member 25 passes downward between the plurality of conveyors 40, whereby the cargo 46 on the bucket 18 is transferred to the group of conveyors 40. The load 46 is then carried out of the frame 1 and conveyed to the next process by the conveyor 42. The cargo 46 is stored on the ascending route 21, and the cargo 46 is moved to the operating section 4 on the third floor 6.
By operating and driving 1, it is possible to carry out (take out) intermittently or continuously. At that time, in order to prevent accidents caused by almost simultaneous operations of the cargo loading section 30 and the cargo unloading section 31, the operation sections 38, 4
A safety circuit is provided and displayed so that when one of the devices is operated, the other cannot be operated.

In the above embodiment, the cargo 46 is transported to the upper floor, but as shown by the imaginary line in FIG. It may also be of a type in which a cargo unloading section 31 is provided opposite the descending path 22 of No. 2 to transport the cargo 46 to the lower floor.

Effects of the invention According to the invention having the above-mentioned configuration, the carried cargo can be received by the cargo receiving device and then always positioned at a fixed position by contacting the stopper surface and the guide plate. Transport can be carried out accurately and stably, and
Storage can be performed using the transport route between the layers.

Moreover, since the load is once stored in the load receiving device and then scooped up by the bucket, there is no excessive impact on the bucket, the chain does not swing, and the load storage operation is smooth.

Furthermore, since loading and unloading can be carried out continuously, loading and unloading can be carried out efficiently.
