Rotary transfer device in blow molding machine

摘要

To realize direct and intermittent rotation of a transfer member by directly coupling the rotary part of a servo motor with a rotary shaft. A supporting board is arranged side by side with working space 3 made vacant above a machine base. The center part of a transfer member arranged on the undersurface of a supporting board 4 is coupled with a rotary shaft 7 of a relatively large diameter inserted through the center of the supporting board and mounted on a bearing. The servo motor 8 provided with the fixing part 8 b inside of the rotary part 8 a of the large diameter in the center of the supporting board 4 is attached to a supporting base 15 erected on the supporting board 4 via a joint 18 on the side of the fixing part 8 b. The rotary part 8 a is mounted on the top of the rotary shaft 7, and thereby the transfer member 6 is constructed so as to be directly rotated with the rotary shaft 7 by the servo motor 8.
