Problems to be Solved by the Invention Jitsuko Sho 49-148
According to the publication of No. 52, the plate-shaped body is lifted at the same place, rotated by 90 °, and returned to the original position. Therefore, the conveying distance cannot be earned during the operation, so that the speed-up in recent years is followed. However, there is a problem that when two stacked glass plates are placed on a support frame and rotated, for example, there is a possibility that the centrifugal force causes a deviation, and the one disclosed in Japanese Utility Model Publication No. 49-133961 has a problem. However, since the supporting part of the article is a suction cup, it cannot be applied to the case of a two-piece laminated glass plate, and an arm is required due to the use of a crank mechanism, which has the drawback of requiring excessive equipment. The actual exploitation 58-106
No. 190 can not be applied to the case of the two stacked glass crows in the same manner as described above, and there is a problem with excessive equipment that requires two lines of the transfer side and the transfer path after the direction change. is there.
