Become.

[0034]

By using the upper and lower conveying rollers,
The transport mechanism is simplified and costs are reduced. By reducing the size of the lower conveying roller, the cost is reduced and the height is reduced.

The height of the pallet is made smaller by making the pallet's transport roller receiving sill material flush with the upper surface of the pallet. The drive device for the transport rollers is integrated into the entrance and exit ports and the traveling cart, and the transport rollers of the parking room and the lift device are connected and rotated, so that the number of drive devices is reduced and the cost is reduced.

Further, since the number of driving devices is small, the rate of occurrence of failures is low, and the maintenance is also improved. Since the rotation is synchronized by connecting and turning, the pallet can be transported reliably, and the reliability of the apparatus is improved.

By separately providing a driving device for transporting the upper pallet and a driving device for transporting the lower pallet, the upper and lower pallets can be transferred at the same time, and the transfer time can be reduced. I'm sorry.
