Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a three-dimensional storage device using pallets, which is employed, for example, in a multi-level parking lot where cars are parked in and out of the parking lot while being placed on pallets.

Conventional technology For example, as a three-dimensional storage device using pallets,
What is shown in Utility Model Publication No. 56-16369 is provided. This involves installing a roller conveyor on a turntable, placing a car on a pallet placed on the roller conveyor, and rotating the turntable to direct the pallet and car toward the car entrance. Then, by running a truck connected to the pallet along a roller conveyor, the pallet and the car are moved on the roller conveyor and are carried into the building of the multi-level parking facility through the car entrance. A delivery roller conveyor is provided on a lift table as an extension of the roller conveyor inside the vehicle entrance. When the pallet and the car are carried into the building through the car entrance as described above, they are further moved on the delivery roller conveyor and stopped at a predetermined position within the cage. When the lift table is lowered, the pallets and cars are transferred from the delivery roller conveyor to the cage. In this way, the car is placed in the cage together with the pallet, and this cage is moved upwards, while at the same time the next cage is moved inside the car door in preparation for the next storage. Also, shipping is the reverse of the above procedure.

Another conventional example, as seen in Japanese Unexamined Patent Publication No. 58-69966, is that after a car enters a building, a pantograph-type lift device is used to lift the car together with pallets to a predetermined floor. This car, along with its pallets, is then delivered to trolleys set up on each floor. This cart moves horizontally,
The car is transported along with the pallet to the desired parking area and parked there. Also, shipping is the reverse of the above procedure.

Problems to be Solved by the Invention According to the above-mentioned conventional type, when a pantograph-type lift device attempts to raise the device to a too high position, the number of pantograph arms increases, which makes the entire device bulky. As a result, it became difficult to maintain that strength. Therefore, there is a limit to the height at which the pantograph type lift device can be raised and lowered, making it unsuitable for use in multi-story parking lots or the like having a certain height or more.

Furthermore, when transporting cars into a building in a multi-storey parking lot, the control of the trolleys that run along the roller conveyor is complicated, and there is also the risk that foreign objects may enter the travel path of the trolleys, causing problems with the running of the trolleys. It was hot.

The object of the present invention is that the lifting height of the lift device is high, that it is easy to control when loading and unloading cargo, and that
The object of the present invention is to provide a three-dimensional storage device using pallets that does not cause any problems.

A delivery device that is movable in the horizontal direction and can freely transfer pallets to and from the storage section is provided on each floor except for the loading/unloading floor, and the loading/unloading floor is installed at an appropriate location within the loading/unloading work space. A lift device that can freely transfer pallets between the and each delivery device is provided, and this lift device is connected to an upright guide column, an elevating member guided by the guide column, and a lift device that moves from the elevating member to the loading/unloading work space. A turntable is formed of a pedestal that protrudes and is located in the interior of the container, and a lifting-side conveyor device that is disposed on the pedestal and has a pallet support surface, and that the turntable faces the lift device on the cargo loading/unloading floor. and a table-side conveyor device that can be freely connected to the elevating-side conveyor device is provided on the turntable.

According to the configuration of the present invention, a load is transferred from the front direction onto an empty pallet placed on a turntable, and after the direction of the load is changed by rotation of the turntable, the load is transferred to the table side conveyor. By sending out a pallet with a load supported by the device and drawing it in by the lifting conveyor device, the pallet is placed on the pedestal while being supported by the lifting conveyor device. Then, the elevating member is guided by the guide column and ascends,
The lift device can stably transport the load together with the pallet to a predetermined floor. After the cargo is delivered to the delivery device together with the pallet, a cart provided on the delivery device moves horizontally, and the cargo is stored together with the pallet in a desired storage section. Moreover, the retrieval can be performed in the reverse order of the above procedure.
