Title: Aligner for sericeous pulse
Inventor: MATSUMOTO TOSHIYUKI
IPC: B65G47/30
Filed: 1986-06-23
Abstract: PURPOSE:To prevent transferred articles from overlapping with one another and make the sorting measure accurate, by installing a separate transfer belt which separates these transferred articles, being conveyed in line, from those not attracted while conveying them in a state of being attracted by the suction hole set up on the top. CONSTITUTION:When transferred articles are fed to the top of an aligning conveyor 3, these articles are aligned in the longitudinal direction, of each position by alternate high-low speed rotation of the round belt stretched across. And, they are dropped on each separate transfer belt 5 moving in the longitudinal direction at a lower part of the round belt by way of a guide plate 17 in a state of being aligned. This separate transfer belt 5 is set up to be longer than the aligning conveyor 3, and suction ports 4 are set up on the top of the belt at the specified intervals, while this separate transfer belt 5 is set up in a state of being gradually tilted from horizontality. Accordingly, only the transferred articles attracted by the suction hole are transferred up to the terminal, and those of overlapped ones are dropped down at an incline. And, only those attracted as being aligned are measured and sorted, thus accurate sorting can be done.

Filed: 1980-10-22
Abstract: PURPOSE: To easily and surely rotate the ring and to improve the workability, by contacting the ring with one side of ring supporting member when a pair of ring supporting members are lifted up.  
     CONSTITUTION: When a piston rod is retreated by a hydraulic cylinder 16 during the period of rolling, ring supporting members 12 and 12' are moved rightward, and located at positions which is deviated by (a) from the center of the ring (b). When the rolling is completed and the upper anvil is lifted up and, at the same time, the ring supporting members 12 and 12' are lifted up by driving eccentric rollers 14 and 14', and the left side ring supporting member 12 is contacted with a ring 2. As the ring supporting member is further lifted up, the ring 2 is rotated rightward by the ring supporting member 12 until the ring contacts with the right side ring supporting member 12'. Finally, the ring 2 is supported by both ring supporting members 12 and 12' at a location which is deviated by (a) from the center of the anvil (b). When the piston of the hydraulic cylinder 16 is extended under this condition, the center of both ring supporting members 12 and 12' coincides with the center of the anvil, and the ring supported by the supporting members 12 and 12' is returned to the center of the anvil. Thus, the ring 2 is rotated for a required amount from the position where the ring 2 received the first rolling.
