2. Description of the Related Art In general, a vertical-circulation-type multi-story parking facility as described above is provided with a pallet installed in a pit below the car, after a vehicle is moved forward into a cage at a vehicle entry position. The direction of the vehicle is changed by 180 ° in a horizontal plane by ascending and descending and turning by the upper turning device, so that the vehicle can be exited from the vehicle entering position in a forward state at the time of unloading.

In such a cage, for example, as disclosed in Japanese Patent Publication No. Sho 63-17988, a positioning pin c is projected from a cage lower member b for holding a pallet a from below, and The positioning holes d provided in the pallet a are guided along the positioning pins c by the lowering operation of the pallet a.
Are positioned on the cage lower member b (see FIG. 18).

[0004]

However, in the above-described conventional positioning method, since the positioning pin c is protruded upward from the cage lower member b, the pallet a must be turned to rotate the pallet a. It must be raised upward by the dimension e, which increases the lifting stroke. For this reason, a hanger for suspending the cage lower member b (not shown)
Otherwise, the vehicle may interfere with the hanger when the pallet a rises. As a result, the upper and lower cage pitches become longer, and the number of vehicles stored is limited.

SUMMARY OF THE INVENTION The present invention has been made in view of the foregoing, and an object of the present invention is to make a positioning pin movable so that the positioning pin is retracted when the pallet is turned so that the positioning pin does not protrude. In other words, the pallet lifting stroke is shortened to shorten the cage pitch, and the number of stored vehicles is increased accordingly.

[0006]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a method for storing a vehicle by circulating a large number of vehicle mounting cages vertically above a pit to store the vehicles. A vertical circulation type multi-story parking system in which a pallet is mounted on a lower part of a cage so as to be able to be pulled out, and a pallet lifting and turning device having a lifting frame and a turning frame supported on the lifting frame so as to be horizontally rotatable is installed in the pit. The following measures were taken for equipment.

That is, a first solution of the present invention is to provide a positioning pin in the pit. When the pallet is turned, the positioning pins are retracted downward to allow the pallet to turn. On the other hand, when the pallet is positioned, the positioning pins are projected upward to penetrate the cage lower member and the pallet from below, and the pallet is inserted into the cage. It is characterized in that it is guided to be engaged with the lower member.

According to a second aspect of the present invention, in the first aspect, a positioning pin is provided on an elevating frame in the pit.

According to a third aspect of the present invention, in the first aspect, a positioning pin is provided on a fixed side in the pit.

A fourth solution of the present invention is characterized in that, in the first solution, a positioning pin is provided on a bottom wall of the pit in the pit, and furthermore, the positioning pin is movably inserted vertically into a lifting frame. I do.

According to a fifth aspect of the present invention, in the first to fourth aspects, a pin protrusion amount determining device is connected to the positioning pin, and the pin protrusion amount at the time of pallet positioning is defined by the pin protrusion amount determining device. It is determined whether or not the amount. Further, an emergency stop device is connected to the pin protrusion amount determination device, and the driving source of the parking facility is stopped when the determination of the pin protrusion amount determination device by the emergency stop device is less than a specified amount. Features.

[0012]

With the above arrangement, according to the first to fourth solutions of the present invention, when a vehicle gets on a pallet of a cage at a vehicle entering position, the above-mentioned pallet mounted on the vehicle is moved from a lower member of the cage by a rising operation of a pallet lifting and turning device. Separated and lifted, then retracted below the positioning pin (evacuated)
In this state, the pallet lifting and turning device rotates the pallet mounted on the vehicle 180 ° in the horizontal plane by the turning operation of the pallet lifting and turning device. By the lowering operation of the apparatus, the pallet is guided by the positioning pins and engaged with the cage lower member.

As described above, since the positioning pins are retracted when the pallet is turned, the pallet does not interfere with the positioning pins even if the rising stroke of the pallet is shortened by the amount that the positioning pins do not protrude. The shorter the stroke, the lower the hanger of the cage, the shorter the upper and lower cage pitches, and the greater the number of stored vehicles.

In particular, in the fourth solution, since the positioning pins are fitted into the lifting frame, the lifting frame is guided by the positioning pins and does not move, so that the lifting operation of the lifting frame is stabilized.

According to the fifth solution of the present invention, if the inverted pallet is displaced with respect to the cage lower member, the projecting operation of the positioning pin is hindered by the pallet, and does not reach the specified amount. Is determined by the pin protrusion amount determination device, the emergency stop device is operated, and the driving source of the parking facility is stopped.

From this, the incomplete positioning of the pallet can be reliably determined, and thereafter, the cage circulation is stopped and safety is maintained.
