Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention is used in the technical field of mechanical parking equipment, and in particular,
The present invention relates to a multi-layer circulation parking device equipped with a turntable for rotating pallets in the loading/unloading room.

(Conventional technology) Conventionally, a multi-layer circulation parking system a+ that adopted a box-shaped circulation system
, ax, as shown in FIGS. 7 to 9, for example, the lateral transfer path C for laterally transferring and accommodating the automobile loading pallet b has two upper and lower layers, that is, the upper lateral transfer path c.
, and a hoistway e for loading and unloading a warehouse, which is formed in the lower horizontal transfer path c2 and equipped with a lift dI for loading and unloading pallets at one end of the horizontal transfer path C, and a lift dZ for pallet circulation at the other end. A circulation hoistway e2 is formed, and an inlet/outlet room r1 is connected to the top of the inlet/outlet hoistway e.
In this case, the turntable gI is used as a lift for loading and unloading pallets)
It was located directly above the +.

In order to park the car at a desired parking position, the car is driven forward onto an empty pallet b that is supported so as to be exposed on the top surface of the turntable gI.
The barrel 1-b is transferred onto the topmost movable rail h of the pallet loading/unloading lift d+, and is lowered, for example, to the upper lateral transfer path C1.

and the pallet row of the lower horizontal transfer path C2 are connected to the upper horizontal transfer path CI, the circulation hoistway e2, and the lower horizontal transfer path C2.
By circulating one pallet b at a time in the clockwise (or counterclockwise) direction in FIG. 8 along the box-shaped circulation path formed by the loading/unloading hoistway e2
The car was stored at a desired parking position along with pallet b.

On the other hand, in order to take the car out of the warehouse, the pallet b is transferred onto the movable rail h of the pallet loading/unloading lift dI by the same box-shaped circulation operation as described above and raised to the top thereof. After this pallet b was transferred to the turntable g1, the direction of the automobile was changed from front to back by the rotation of the turntable g, and the automobile was taken out of the storage room f+ by moving forward.

In addition, in the rectangular loading/unloading room f2 as shown in Fig. 9,
A turntable g2 is provided at a distance from directly above the pallet loading/unloading lift d+ in the direction of travel of the vehicle (pallet length direction), and its loading/unloading operation is controlled by the pallet loading/unloading lift d+. After entering turntable g2 in reverse from the top of the car, the car was changing direction.

(Problems to be Solved by the Invention) However, in the conventional multi-layer circulation parking system "I+a2", the radius of the turntable g++gz is large (
For example, 3000 mm), therefore, below it, that is, in the hoistway el for loading and unloading, there is a wide idle space (for example, about 1500 mm
+nm)j is formed, which is extremely uneconomical from the viewpoint of effective space utilization.
+ (See Figure 7) or at the top of the pallet loading/unloading lift d (see Figure 9). There is an inconvenience that the box-shaped circulation operation in preparation for shipping cannot be performed unless the pallet b loaded with the pallet b returns to the pallet row on the lateral transfer path C.

In view of the above-mentioned conventional problems, the present invention provides a multi-layer circulation parking system that allows other vehicles to quickly prepare for exiting even if an exiting vehicle is waiting to exit directly above the pallet loading/unloading lift. is to provide.

(Means for Solving the Problems) A means for solving the above problems of the present invention is that a horizontal transfer path for accommodating automobile loading pallets is formed in a plurality of layers above and below, and one end of the horizontal transfer path is A loading/unloading hoistway equipped with a pallet loading/unloading lift is formed, and a circulation hoistway equipped with a pallet circulation lift is formed at the other end, which is connected to the top of the warehouse loading/unloading hoistway. In the case where a turntable is provided in the loading and unloading room, a pallet lifting means is provided directly above the lift for loading and unloading the pallet, and a means for lifting the pallet is provided on the side opposite to the horizontal transfer path for the loading and unloading hoistway and each horizontal transfer path. It is equipped with a pallet standby lift for loading and unloading pallets.

(Function) The effect of the above means is that when a pallet loaded with vehicles is waiting to be discharged directly above the pallet loading/unloading lift, if another vehicle receives a reservation for unloading, the pallet will be stored in the pallet waiting lift. By pulling out the other pallets that had been stored in the loading/unloading hoistway and connecting the rows of pallets in the horizontal transfer path, the reserved pallets can now be placed in the upper horizontal transfer path, lower horizontal transfer path, circulation hoistway, and the pallet loading/unloading hoistway. After being moved along a box-shaped circulation path connected to a lift or a pallet standby lift, it is accommodated in the pallet standby lift and left on standby.

The automobiles loaded on the pallet 2A accommodated on the pallet 2a are reserved for leaving the warehouse. [See Figure 6(a)]
.

(2) The movable rail 13a is adapted to each horizontal transfer path 12a, 12b by circulation drive of the pallet loading/unloading lift 13, and the pallet 2C at the end is used for pallet loading/unloading by lateral feeding of the pallet row in the upper horizontal transfer path 12a. When entering the lift 13, the movable rail 18a on the upper layer side of the pallet standby lift 18 is lowered to connect the pallet 2B with the pallet row, and the pallet row is transversely fed to the pallet circulation lift 15 side to remove the pallet 2B. After the pallet is pulled back to the loading/unloading lift 13, each balent row is moved to the loading/unloading hoistway 14,
Box-shaped circulation movement is performed in the lower lateral transfer path 12b, the circulation hoistway 16, and the upper lateral transfer path 12a [see FIG. 6, etc.].

(3) When the pallet 2A enters the pallet loading/unloading lift 13, the pallet 2A is sent to the upper side of the pallet standby lift 18 by lateral movement only on the upper horizontal transfer path 12a, and then the movable rail 18a is raised. Let me barre l-2

When the outgoing vehicle is taken out from the pallet 2 that has been evacuated from the top of the pallet in/out lift 13, the balent 2
The movable rail 1 is lowered by the downward drive of the valent lifting means 17.
3a, the movable rail 13a is driven downward to connect with the pallet row on the upper horizontal transfer path 12a, thereby completing the preparation for the subsequent box-shaped circulation operation [see Fig. 6(d)]. .

(5) When carrying out the barrette 2A from the state shown in FIG. 6(C), lower the movable rail 18a on the upper layer side of the barrette standby lift 18 and connect it to the pallet row on the upper layer horizontal transfer path 12a. 6(e)], the pallet row is moved horizontally by one pallet to the pallet circulation lift 15 side, and the pallet 2A is entered into the pallet loading/unloading lift 13 (see Figure 6). 1-2A is conveyed to the top by the lift 13 for pallet loading/unloading and is unloaded.

(Effects of the Invention) With the above-described configuration, the present invention can easily perform the box-shaped circulation operation even when another vehicle is reserved for leaving the warehouse while the leaving vehicle is placed directly above the pallet loading/unloading lift. Because it is possible to prepare a vehicle for unloading, it is done over a relatively short distance, which not only improves work efficiency and reduces running costs, but also makes effective use of idle space around the hoistway for loading and unloading. There is an advantage.
