Apparatus for transporting containers in labelling machines
First Claim
1. In a machine for multiple treatment of containers having circular portions with different diameters, transporting apparatus comprising a carrier tunable about a first axis, means for turning said carrier about said axis in a first direction;
- a succession of container supporting elements mounted on said carrier for orbital movement about said axis along a predetermined path, each of said elements being turnable about a discrete second axis parallel to said first axis;
means for treating successive containers at a first portion of said path;
means for treating successive containers at a second portion of said path a predetermined distance downstream of said first portion;
means for rotating said elements about the respective second axes in a second direction counter to said first direction, including first and second cams adjacent said path and first and second followers provided on each of said elements and respectively tracking said first and second cams; and
means for adjusting said cams relative to said path as a function of the diameters of circular portions of containers which are supported by said elements, said adjusting means including means for moving said cams along said path in and counter to said first direction.

Abstract
Apparatus for transporting containers having circular portions with any one of a number of different diameters first along an adhesive applying unit and thereupon past one or more units which apply labels all the way around the circular portions of the containers has a rotary turntable with a set of depending rotary supporting elements for discrete containers. The supporting elements are rotated about their own axes, while orbiting about the axis of rotation of the turntable, by two arcuate cams which are adjacent the path of orbital movement of the supporting elements and are tracked by roller followers provided on disc-shaped holders at the upper ends of the supporting elements. Adjustment of the apparatus for the transport of containers having circular portions of different diameters is effected by moving the cams in the circumferential direction of the turntable. The positions of the various treating units remain unchanged.
