[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a multi-layer box-type circulating parking system having a turning device.

[0002]

2. Description of the Related Art Japanese Patent Publication No. 4-75984 discloses a multi-layered box-type circulating parking system in which a turning device is installed on an entry / exit floor so that a vehicle can be entered and exited forward.

[0003] Japanese Patent No. 2612479 discloses a multi-layer box-type circulating parking system in which a turning device is installed at the lower end side or in the middle of an elevating lift forming a circulation path on a storage floor.

[0004]

By the way, the former turning device of a parking device is provided with a turntable having an opening for raising and lowering a pallet, and a vehicle-mounted pallet is circulated by a lifting lift provided on the back of the turntable. The vehicle is turned by the turning motion of the turntable while being lifted from the lifting lift. For this reason, the load of the on-vehicle pallet and lifting lift is applied to the turntable, so the turntable must be solid, and the turning device becomes heavy, and the heavy turning device is supported on the floor of the loading and unloading floor. Therefore, this floor must be strengthened. Furthermore, since the pallet moves up and down the opening of the turntable, the outer diameter of the turntable is larger than the diameter of the turning trajectory of the pallet, and the floor area of the loading and unloading floor must be widened accordingly.

On the other hand, in the latter parking device, when the pallet is turned by the turning device, an empty space is provided so that the pallet on the turning device does not interfere with the pallet on the adjacent lateral transfer path, or the pallet on the lateral transfer path is set. Since it must be saved, the storage space is wasted and the control of the circulation operation becomes complicated.

The present invention has been made in view of the above points, and an object of the present invention is to prevent the floor surface of the entry / exit floor from being strengthened and the floor area not to be secured more than necessary, and the storage floor It is to eliminate useless empty space and complication of the control system of the device.

[0007]

In order to achieve the above object, the present invention provides a third lifting lift separate from the first and second lifting lifts of the circulation path, and mounts a turning device on the third lifting lift. It is characterized by doing so.

Specifically, the present invention comprises an upper and lower horizontal transfer path and first and second lifting lifts provided at both ends thereof so as to be able to move up and down. As a premise of the multi-layered box-type circulating parking device, a circulation path for circulating a plurality of pallets is provided on the storage floor, and vehicles are transferred between the storage floor and the storage floor to store and store the vehicles. I took such a solution.

That is, in the invention according to claim 1, the first and second lifts are circulation lifts for moving pallets between the upper and lower horizontal transfer paths, and the storage floor has the above-mentioned lifts. A third lifting lift for moving the vehicle between the loading and unloading floor and the storage floor by moving up and down on the hoistway where the first lifting lift goes up and down and its extension is provided, and the pallet is mounted on the third lifting lift. A turning device for holding the turning device is mounted.

According to a second aspect of the present invention, on the above-mentioned premise, the hoistway of the first elevating lift extends to the loading / unloading floor, and the first elevating lift is provided between the upper and lower lateral transfer paths. It has a circulation function of moving the pallet at the same time, and a relay function of moving up and down the hoistway to relay between the loading / unloading floor and the circulation path, while the second elevating lift is provided between the upper and lower lateral transfer paths. The third lifting lift equipped with a swinging device for swingably holding the pallet is a hoistway for the first lifting lift, which is a circulation-only lifting lift for moving the pallets at the storage floor and is directly below the storage floor of the storage floor. The third lifting / lowering lift is capable of advancing / retreating with respect to the first lifting / lowering lift by moving up / down in the advanced state.

With the above structure, in the inventions according to claims 1 and 2, since the turning device is mounted on the third lifting lift between the entry / exit floor and the circulation path, the floor surface of the entry / exit floor. Need not be strengthened more than necessary. Further, since the vehicle-mounted pallet is lifted at the time of turning by the original lifting function of the third lifting lift, the turning device becomes lighter because a separate lifting lift is not required. Further, since there is no need for a turntable having an opening and there is only a space for the pallet to turn, it is not necessary to secure a floor area on the entry / exit floor that is unnecessarily large. In addition, even if the pallet turns, it does not interfere with the pallet on the circulation path, and there is no need for a wasteful empty space or a complicated control system for avoiding interference. In particular, in the invention according to claim 2, since the third lifting lift is retracted and retracted from the hoistway of the first lifting lift, the circulation function and the relay function of the first lifting lift are not hindered, and the loading / unloading is performed. It is done efficiently.
