Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pallet delivery device for delivering a vehicle-mounted pallet using a swing arm between a moving body that moves up and down or travels and a parking room.

[0002]

2. Description of the Related Art In a multi-story parking facility in which parking rooms are arranged on a plurality of parking floors and vehicles are loaded and unloaded via pallets, a moving body (elevation platform or traveling vehicle) that moves up and down or travels.
Each is equipped with a pallet delivery device. This pallet delivery device is conventionally equipped with a drive type roller conveyor device, but the roller conveyor device requires a plurality of drive rollers and a power transmission mechanism, and the pallet is transferred between the pallet and the parking room. Since a device for pushing and pulling is also required, there is a problem that the device mounted on the moving body becomes complicated and the weight increases.

For this reason, in recent years, a swivel arm for swiveling around a vertical axis is provided in a moving body, and an engaging roller provided at a free end portion of the swivel arm is provided in an engaging groove formed on a side portion of a pallet. A swing-arm type pallet delivery device has been proposed which delivers a pallet between a parking room and a moving body by engaging and rotating the slewing arm.

[0004]

By the way, normally, when the engaging roller of the turning arm is engaged with the engaging groove provided in the pallet of the parking room, the engaging roller is projected into the parking room, and It can be smoothly engaged by swiveling from a direction substantially perpendicular to the transfer direction and engaging. Further, since it is better to start moving the pallet slowly at the time of starting the transfer of the pallet, the pallet delivery posture for delivering the pallet and the pallet mounting posture for stopping the pallet on the moving body are separated by 180 degrees and the revolving arm is along the transport direction. Set to the direction.

Further, it is more rational that the parking rooms are arranged on both sides of the moving path of the moving body and the pallets on both sides can be handled by the same swing arm. Then, it is necessary to form a gap between the pallet in the parking room and the pallet at the pallet mounting position of the movable table to avoid interference.

Therefore, the swing arm type pallet delivery device is provided with an arm swiveling device for the swivel arm and an arm shift device for shifting the swivel arm in the transfer direction. The arm revolving device and the arm shift device are respectively driven by different driving devices (for example, electric motors), and a synchronizing device that electrically controls them so as to be synchronized with each other is provided.

However, in recent years, in this type of multi-story parking facility, along with the demand for cost reduction, an accurate and reliable drive structure has been demanded. For example, due to electrical noise, the swing arm is engaged. Even if the engagement position of the roller is slightly deviated, the engagement roller may not be fitted in the engagement groove, which makes it difficult to transfer the pallet. Further, since the arm turning device and the arm shift device are separately provided, the delivery device for the moving body is complicated and the weight is increased.

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above problems and to provide a pallet delivery device for a multi-story parking facility, which enables cost reduction, weight reduction, and stable delivery of pallets.
