By the way, when a long-sized baggage is loaded on a pallet and loaded into a loading section of a conveyor line, the fork of a forklift is placed at a position of the pallet such that the balance of the center of gravity of the baggage is approximately in the longitudinal direction. Insert it, transport it with a forklift, and put it in the conveyor line. Therefore, when the loading port is provided only in the conveying direction on the conveyor line, when the long-sized handling baggage described above is loaded on the conveyor line, the handling baggage is in a state of being long in the width direction of the conveyor line. Is brought in. When a long-sized baggage is loaded in such a state, the center of gravity of the baggage deviates from the center in the width direction of the conveyor line during transportation on the conveyor line, and the baggage is biased to one side of the conveyor line. , Could not be transported smoothly.

In order to solve the above-mentioned inconveniences, the width of the conveyor line has been widened according to the length of the conventionally handled baggage, and the handling baggage such as a turntable which can be rotated by 90 ° at the loading / unloading section of the baggage to be handled. By adding a mechanism to change the direction of, the center of gravity of the cargo handled can be almost aligned with the widthwise center of the conveyor line.
