Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to an improvement of a horizontal circulation parking device, and particularly to measures for increasing transfer efficiency.

(Prior Art) In recent years, due to soaring land prices and difficulty in obtaining construction land, there has been a significant increase in mechanical parking systems that are installed underground instead of using above-ground space in order to make effective use of land. and,
As such a mechanical parking device, for example,
As disclosed in Publication No. 15059, a plurality of pallets on which vehicles are loaded are rectangular, consisting of two horizontal transfer paths arranged in parallel with each other and two vertical transfer paths connecting 20 vehicle horizontal transfer paths. A horizontal circulation type configured to allow circulation on a circulation path is generally well known.

(Problem to be solved by the invention) However, in the above-mentioned conventional horizontal circulation parking device, when a large number of vehicles are parked, the number of pallets transferred along the horizontal transfer path naturally increases, and the circulation transfer distance increases. Because of the length, it takes a long time to circulate and transport the target pallet to the storage/unloading position during loading/unloading, resulting in a problem that the transfer efficiency decreases.

The present invention has been made in view of the above points, and its purpose is to move the target pallet to the storage/output position by taking appropriate means that can shorten the actual circulation transfer distance of the pallet. The objective is to reliably improve the transfer efficiency by performing circular transfer in a short period of time.

(Means for Solving the Problems) In order to achieve the above object, the solution means of the present invention is to add a vertical transfer path to a substantially central portion in the longitudinal direction of the horizontal transfer path, and to provide a vertical transfer path on both sides of the vertical transfer path. Two independent circulation paths are constructed, and a lifting means is provided next to the additional vertical transfer path.

Specifically, a plurality of horizontal transfer paths for horizontally transferring pallets on which vehicles are placed are arranged in parallel, and first and second vertical transfer paths for vertically transferring pallets between the horizontal transfer paths are arranged in parallel with each other. They are provided so as to intersect one end and the other end of the lateral transfer path. Further, a third vertical transfer path for vertically transferring the pallet between the horizontal transfer paths is provided so as to intersect approximately at the longitudinal center of each of the horizontal transfer paths. Further, the third vertical transfer path divides each of the horizontal transfer paths to form first and second circulation paths, and the first and second circulation paths divide diagonally two vacant spaces where no pallets are present. Each pallet is circulated by vertically and horizontally transferring the plurality of pallets by placing the pallets at different positions.

In addition, a lifting means is provided adjacent to the third vertical transfer path,
The elevating means allows each pallet to be moved up and down in order to move vehicles into and out of the warehouse.

(Function) According to the above configuration, in the present invention, a plurality of pallets on which vehicles are placed can be placed in the first pallet, which is partitioned by the third vertical transfer path that intersects approximately at the center in the longitudinal direction of the plurality of horizontal transfer paths arranged in parallel.
The pallets are circulated through the second circulation path by arranging two empty spaces in diagonal positions and performing vertical transfer and horizontal transfer, and are provided adjacent to the third vertical transfer path. The elevating means allows the vehicle to be moved up and down in order to enter and exit the warehouse.

From this, it can be seen that the circulation transfer distance of each pallet is the same when the third vertical transfer path is not provided, that is, when the third vertical transfer path is not provided, the first The second vertical transfer path is shortened by half compared to the circulation path that transfers pallets vertically, and the target pallet can therefore be circulated to the storage/output position in a short time, improving transfer efficiency. This will definitely be done.
