ABSTRACT:
A transfer device of the opposed finger type is disclosed for transferring an article along an arcuate path of travel between two stations while rotating the article, so that transfer from one station to another is effected while simultaneously turning the article 180 degrees about an axis substantially normal to the path of travel. The transfer device has a subframe with a fixed reaction element mounted thereon and an elongated transfer arm mounted on the subframe in a manner which allows the transfer arm to rotate about its longitudinal axis as well as pivot with respect to the subframe. One end of the transfer arm has a rotating element which is engaged with the fixed reaction element which causes the transfer arm to rotate about its longitudinal axis as the transfer arm pivots. The other end of the transfer arm has grasping elements to hold an article or workpiece as it is transferred from one work station to another by the pivoting action of the transfer arm, the article also being rotated as the transfer arm rotates in response to the engagement of the rotating element with the reaction element. Apparatus is provided to cyclicly pivot the transfer arm and rotate and transfer the article in timed sequence from one work station to another. Transfer arms may be arranged in tandem or ganged configuration for transfer of the article sequentially along a series of stations.
