DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multistage type storage in which a plurality of underframes on which articles are placed are connected and stored in a multistage storage, and can be sequentially taken out. And a storage processing device for the truck.

[0002]

2. Description of the Related Art A trolley or a frame on which articles are placed using a traverser is stored in a storage compartment partitioned into a number of rooms,
In addition, there are a first-in first-out method and a first-in first-out method as a take-out method.

[0003] In the former case, since a bogie or a frame is pushed in and pulled out from one side of the storage, a parent-child traverser is mainly used as a traverser. In other words, the parent traverser traverses in front of the storage, the child traverser directly stacks the trolley or underframe, mounts the elevating device, enters the storage, and stores the trolley or underframe on which articles are sequentially loaded from the back. When the child traverser is to be pulled out, the child traverser pulls out the bogie or underframe from the entrance side of the storage and transfers it to the parent traverser. In this case, there is only one storage entrance.

In the latter case, since the storage is open front and rear, the entrance traverser traverses the entry side and pushes the bogie or underframe into the storage, while the bogie or platform pushed out from the exit side. The frame is transferred to the exit traverser and processed.

[0005]

In the prior art, a method in which a trolley or underframe is moved in and out from one side of a storage by a child traverser requires complicated equipment and many troubles.
The equipment becomes expensive. In particular, in the case of a storage for the purpose of curing concrete products, since electrical components run in the storage of high heat, many troubles occur in particular.

Further, in the method in which a bogie or underframe is pushed in from one side of the storage and pushed out from the other side, doors are required on both sides, and traversers need to be traversed on both sides, so that the installation area of the apparatus is large. In addition, the storage often occupies the central part of the factory building, and the waste of equipment is large compared with the one-sided type.

Further, in the conventional storage, it is not possible to exchange articles at different heights with the traverser so as to stack the trucks or underframes only by arranging them in a plane, and the area of the storage is reduced. We did not use it.

The present invention solves such a problem, and it is possible to efficiently push in and pull out the underframe on which articles are placed by using only one traverser and without using a child traverser. Further, it is an object of the present invention to provide an apparatus for processing a trolley into a multi-stage storage, in which articles having different heights and lengths can be stored if the width is constant.

[0009]

SUMMARY OF THE INVENTION The present invention provides a storage in which storage chambers having a fixed width provided with multi-stage guide rollers are arranged in parallel, a traverser traversing the front surface of the storage, and a traverser mounted on the traverser. A mounting table for mounting a frame on which articles are mounted, which is provided so as to be able to move up and down. A latch having a fitting groove, a locking shaft horizontally fitted to an end surface of the underframe opposite to the storage box, and a fitting shaft of a latch provided in a succeeding underframe fitted therein; A rotating chain having a chain hook attached to the gantry and transferring the underframe to and from the storage chamber; a underframe pushing claw and an underframe extracting claw that are raised and lowered by the first cylinder at a distal end; Before moving back and forth by the second cylinder toward the storage room The traverser is provided with a moving frame provided on the mounting base and a push-up cylinder attached to the mounting base for removing the latching groove of the latch from the locking shaft, and the traverser stops in front of each storage chamber to guide the mounting base. According to the height of the step provided with the rollers, a plurality of frames mounted on the mounting table were sequentially pushed into the storage room, and all the frames stored in the storage room were connected when the frame was pulled out from the storage room. The trolley is stored in a multi-stage storage box, which is pulled out from the storage room, and the fitting grooves of the latches are removed one by one from the locking shaft one by one from the front, so that the trolley is transferred and carried out on the mounting base. It concerns the device.

When the underframe is pushed into the storage by the storage processing device for the carriage in the multi-stage storage, the platform is raised and lowered to adjust the height of the storage stage, and a rotating chain having a chain hook is provided. When the underframe is pushed into the storage by the underframe pushing claw, and then the underframe is pushed in sequence, a plurality of underframes can be connected and continuously pushed by the latch and the locking shaft, and the By changing the height of the frame and repeating the same operation, a plurality of underframes can be connected to other stages and pushed continuously.

When pulling out the underframe from the storage, the underframe can be pulled out by pulling out the underframe by the underframe pulling-out claw and the rotating chain, and the underframe can be pulled out. When the latch of the underframe is pushed up by the push-up cylinder and removed from the anchoring axis of the next underframe, the next underframe is left in the storage, and one underframe on which articles are placed can be carried out by the traverser. it can.
