Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle storage facility for temporarily storing a vehicle and changing a transportation cycle at a connection portion between the transportation line for transporting the vehicle and the transportation line.

[0002]

2. Description of the Related Art Conventionally, in a storage facility for sending out a car, for example, transferred from two transfer lines to the next two transfer lines by changing the transfer cycle, the car is mounted on an integral pallet. Temporarily stored in a storage line,
It is sent out sequentially for each transport cycle.

[0003]

However, the pallet needs to have at least a size for mounting the left and right front wheels and rear wheels, is suitable for a large vehicle type, and is required to have a predetermined strength. Therefore, the pallet becomes large and heavy. There is a tendency. Therefore, when the pallet to be circulated and used becomes large and heavy, there is a problem that a device for circulatory movement also becomes large and a large space is required.

An object of the present invention is to provide a vehicle storage facility which can be made compact by using a divided pallet.

[0005]

In order to achieve the above object, the invention according to claim 1 of the present invention comprises two pallet bodies of the same structure for mounting front and rear right wheels and front and rear left wheels respectively. Car storage equipment that mounts cars on divided pallets, temporarily stores cars that are transported from one or more transport lines and sends them to one or more transport lines, and transports the cars onto the empty pallet body. A receiving line, a storage line for temporarily storing the in-vehicle pallet body carried in from the receiving line, a shipping line for carrying out the car from the in-vehicle pallet body carried out from the storage line, and an empty pallet body for collecting from this shipping line. Pallet waiting line for temporary storage of the pallets and the pallet supply line for sequentially sending empty pallet bodies to the loading line A pallet supply line, an empty pallet body for the right wheels and an empty pallet body for the left wheels are respectively sent to the left and right sides of the warehousing line, and each pallet body is shifted to the warehousing line side. It is configured to be supplied.

According to the above structure, by using the divided pallet bodies, the pallet bodies are moved close to each other and transferred and stored on a line for circulating and transporting the empty pallet bodies, so that many pallet bodies can be transferred to a certain route. The pallet body can be held, and this makes it possible to handle higher speeds.
Further, since the pallet supply lines for circulating and transferring the empty pallet body from the standby line to the storage line are formed on both sides of the storage line, the equipment can be downsized as compared with the case of using one large pallet.

Elevator device 3 for leaving the vehicle from the leaving lines 14A, 14B
1 is transferred to the first floor F1 via the first and second lifting lines 15A and 15B, and the transfer cycle T ₃ + T ₄
(T ₃ + T ₄ = T ₁ + T ₂ ), and the third and fourth transfer lines 1
It is carried out to 1C and 11D.

On the other hand, the pallet bodies 3 and 3 are composed of the first and second pallets.
The vehicle M is mounted at the start ends of the warehousing lines 12A and 12B, and the first and second warehousing lines 14A and 14B from the first and second warehousing lines 12A and 12B through the storage line 13.
After being sent to the vehicle M, the vehicle M is transferred from the recovery line 16 to the standby line 18 of the third floor F3 via the ascending line 17 by the pallet recovery elevator device 32 and temporarily stored. Furthermore, from the standby line 18 to the first and second
A pallet supply line PR is formed between the starting ends of the storage lines 12A and 12B. The two sets of four pallet supply lines PR are separated from the third floor F3 by the first and second return lines 19A and 19B branched from the standby line 18 and the first and second pallet supply elevator devices 33A and 33B. 1st and 2nd warehousing line 1 of floor Float F2
The first and second descending lines 20A and 20B, which are descended and conveyed to the outside of the 2A and 12B, and the first and second storage lines 12
It is composed of first and second shift lines 21A and 21B which are circulated and transferred to the start ends of A and 12B.

As shown in FIG. 2, by means of a transfer device for loading (described later), the pallet bodies 3, 3 of the first and second warehousing lines 12A, 12B are transferred from the conveyor devices of the first and second transfer lines 11A, 11B. The car M is loaded on top. 1st, 2nd
A pair of left and right storage chain conveyors 12a and 12b for transporting the vehicle-mounted pallet bodies 3 and 3 into which the vehicle M is loaded and mounted are respectively arranged in the storage lines 12A and 12B, and at the start end position. Elevating shift roller conveyors 21a and 21b for guiding the empty pallet bodies 3 and 3 from the first and second shift lines 21A and 21B are provided.

The lateral feed storage line 13 is provided with, for example, 3 to laterally feed the vehicle-mounted pallet bodies 3 and 3.
A plurality of row side chain conveyors 13a are connected and arranged in series, and the first and second storage lines 12A, 12 are arranged.
At a position corresponding to B, elevator conveyors 12c and 12d for raising and lowering are provided which can be raised and lowered by a raising and lowering cylinder device. Therefore, the receiving chain conveyor 12
Roller conveyors 12c, 12 for lifting and unloading from a, 12b

As a result, a large number of pallet bodies can be held at a fixed distance, and it is possible to cope with speedup.

Further, since the pallet body 3 has the same structure in which either the left or right wheels can be mounted, the transfer from the standby line 18 to the first and second return lines 19A, 19B can be easily carried out.

Furthermore, the pallet loading line allows the empty pallet bodies 3 and 3 to be circulated and transferred from the standby line 18 to the warehousing lines 12A and 12B from both sides of the warehousing chain conveyors 12a and 12b. The device can be downsized as compared to the case of using one large pallet.

[0033]

As described above, according to the present invention,
By using the divided pallet bodies, by moving and storing the pallet bodies close to each other on the line for circulating and transporting empty pallet bodies, it is possible to hold many pallet bodies in a certain route, which enables high speed operation. It is also possible to deal with. In addition, a pallet supply line that circulates the empty pallet body from the standby line to the storage line,
Since it is formed on both sides of the storage line, the equipment can be downsized as compared with the case of using one large pallet.

Further, by providing guide means for guiding the guide member projecting at the front and rear positions in the transport direction at the center of the long side of the pallet body in the standby line which is fed laterally so that the long side approaches, The vertically long pallet body can be continuously conveyed in the width direction, and the pallet body does not tilt and become clogged as in the case where guides are provided on both sides.
It can be transported smoothly.
