<p>Article handling apparatus comprises one or more handling arms for performing operations on articles as those articles move continuously through a work station without slowing down or stopping. The operations that may be performed include direction changing with or without changes in the orientation of the articles, assembly, processing or wrapping. Each handling arm (54) is pivotally mounted on a first rotary member (56) and comprises cam means (58) engaged by a cam follower (60) mounted on a second rotary member (61). The shapes of the cam means (58) and the circular paths of the handling arm pivots (55) and cam followers (60) are such that the handling arms maintain a fixed angle of presentation through the handling zone, then rotate in the opposite sense to the first rotary member (56) to retard their tip speeds, then move laterally from the path of the articles to be handled, and finally rotate in the same sense as the first rotary member to approach the handling zone to repeat the cycle.</p> |
