Description

The present invention relates to a mechanical parking device in which a vehicle gets on and off at a warehousing / delivery section.

There are various types of mechanical parking devices such as an elevator system and a vertical circulation system.

In these mechanical parking devices, an entry / exit section is provided inside the building, and an entry / exit port communicating with the entry / exit section is provided on the wall surface of the building. An opening / closing door is provided at the entrance / exit (see, for example, Patent Document 1).

In this type of mechanical parking device, when a start-up operation for loading and unloading is performed on the operation panel at the time of loading and unloading, the machine related to the transportation of the pallet starts to move, and the called target pallet is placed on the storage shelf. It is transported from such a storage location to the warehousing / delivery section.

In the case of warehousing, the pallet to be called becomes an empty pallet, and when this empty pallet arrives at the warehousing / delivery section, the door of the warehousing / delivery port opens. In this state, the user enters the warehousing / delivery section through the warehousing / delivery port and stops the vehicle on the empty pallet. Next, the user gets out of the vehicle and exits from the warehousing / delivery section through the warehousing / delivery port.

On the other hand, in the case of warehousing, the pallet to be called is the pallet on which the vehicle is mounted, and when this pallet arrives at the warehousing / delivery section, the door of the warehousing / delivery port opens. In this state, the user enters the entry / exit section through the entry / exit port, gets on the vehicle on the pallet, drives the vehicle, and goes out of the entry / exit section through the entry / exit port.

After that, when the door is closed on the operation panel, the mechanical parking device closes the door of the entrance / exit after confirming whether or not there are any people left in the entry / exit section by the detector.

After closing the door of the entrance / exit, in the mechanical parking device, when the next activation operation is performed on the operation panel or at the set timing, the machine related to the transportation of the pallet starts to move and enters. The pallet of the delivery section is transported to the storage location and stored.

Therefore, the entrance / exit section of the mechanical parking device is a boarding / alighting room where people can enter and get in and out of the vehicle when the entrance / exit is open, and a pallet is used when the entrance / exit is closed. This is the area where the operation of the machine related to the transportation of the door occurs. Machine operations that occur in the warehousing / delivery section in connection with the transportation of the pallet include, for example, the operation of turning the pallet by the turntable provided in the warehousing / delivery section, and transporting the vehicle between the warehousing / delivery section and the storage location. The operation of transport devices (carryers) such as cages and lifts, and the movement of movable platforms at locations that interfere with the operation of turntables and transport devices.

Therefore, if the door of the warehousing / delivery port is closed with a person remaining in the warehousing / delivery section and the operation of the machine is started, the person in the warehousing / delivery section operates in the warehousing / delivery section. There is a possibility of contact with the machine.

Further, at the time of maintenance of the mechanical parking device, the maintenance worker may operate the machine in the warehousing / delivery section while the maintenance worker is in the warehousing / delivery section.

Therefore, in the mechanical parking device, the outer edge of the operating range of the machine operating in the warehousing / delivery section, for example, the turning range of the pallet by the turntable, is displayed with yellow paint on the floor of the warehousing / delivery section. It is becoming popular. In addition, in the mechanical parking device, the place where contact with the operating machine can be avoided because it does not overlap with the operating range of the machine operating in the warehousing / delivery section can be displayed with green paint. It is becoming more and more done.
