DETAILED DESCRIPTION OF THE INVENTION

[0001]

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

[0002]

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

[0003]

However, the pallet needs to be large enough to hold at least the left and right front wheels and rear wheels, is adapted to a large vehicle type, and requires a predetermined strength. There is a tendency. Therefore, when the pallets used in circulation are large and heavy, there is a problem that a device for circulating the pallets becomes large and a large space is required.

An object of the present invention is to provide a car storage facility that can be made compact by using divided pallets.

[0005]

In order to achieve the above object, the invention according to claim 1 of the present invention comprises two pallet bodies having the same structure and having right and left front wheels and left and right front wheels, respectively. Car storage equipment that mounts cars on split pallets, temporarily stores cars transported from one or more transport lines, and sends them out to one or more transport lines, and loads the cars onto empty pallet bodies. An incoming line, a storage line for temporarily storing the in-vehicle pallet body brought in from the incoming line, an outgoing line for taking out the car from the in-vehicle pallet body taken out of the storage line, and collecting the empty pallet body from this outgoing line. A pallet standby line for temporarily storing the pallets, and a pallet supply line for sequentially sending empty pallets from the pallet standby line to the carry-in line Pallet supply line, the empty pallet body for the right wheel and the empty pallet body for the left wheel are sent to the left and right sides of the receiving line, respectively, and each empty pallet body is shifted to the receiving line side. It is configured to supply.

According to the above configuration, by using the divided pallet bodies, the pallet bodies are moved close to each other on the line for circulating and transporting the empty pallet bodies, so that many pallet bodies are transported and stored in a fixed path. The pallet main body can be held, which can respond to high speed.
Further, since the pallet supply lines for circulating and transferring the empty pallet main 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 using one large pallet.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Here, an embodiment of a car storage facility according to the present invention will be described with reference to FIGS.

As shown in FIG. 3, the divided pallets used for this storage facility include right and left wheels 1R and 2
R and two pallet bodies 3 of the same structure each mounted with front and rear left wheels 1L and 2L. The two pallet bodies 3 are integrated via the vehicle body MB, and the pallet body 3 is synchronously driven by the transfer device. Transported.

The pallet body 3 has a rectangular shape that is long in the front-rear direction when viewed in plan, and has a locking portion 4 formed at a front portion thereof, which is a locking portion for locking the front wheels 1R and 1L by slightly dropping them. . On both sides of the long side 3a of the pallet body 3,
A buffer block (buffer member) 5 made of a synthetic rubber or the like having a large thickness is attached to the pallet body 3. When the pallet bodies 3 approach each other in the left-right direction in an empty state, the shock at the time of collision is reduced, and the gap is narrowed in the left-right direction. When transporting,
A gap 6 (FIG. 4) for detection by the detector is formed. A pair of guide rollers 7, which are guided members, are guided by guide rails (FIG. 4) serving as guide means at the center left and right positions of the long side portion 3a when transported in the left and right direction.
