Abstract
The pick-up device comprises a plurality of pick-up members connected together and articulated by means of arms so as to be disposed at the vertices of a polygon. Cam surfaces defined by the sides of slots provided in one or more motion plates allow the geometry, and possibly the length of one or more sides of the polygon to be varied. It is thus possible selectively to vary the geometry of the arrangement of articles held by the device during transfer thereof, possibly also causing the distance between groups of separate pick-up members to be varied.
Claims11
A pick-up device, comprising:
- a first array of movable pick-up members;
- articulated linkage members directly connecting pick-up members in said first array to each other, the pick-up members being located at pivot points of said articulated linkage members;
- and
- guide means for guiding movement of said pick-up members, said guide means comprising cam surfaces along which said pick-up members slide;
- whereby the pick-up members move in coordinated, linked fashion from a first configuration in which the pick-up members are located at the vertices of a first polygon to a second configuration in which the pick-up members are located at the vertices of a second polygon.
