Labelling machine for objects such as bottles or the like

摘要

A labelling machine for bottles or the like includes several stations located behind one another along a track. The stations include an adhesive application station, a label feed station and a label transfer station. There are three extracting elements which are each mounted to rotate on a rotating support to be moved past the stations during each rotation of the support. Each extracting element has an outwardly-curved receptacle surface for the label which rolls along the stations. The drive for each extracting element is a cam drive, which comprises common, stationary double cam discs for all the extracting elements with two cams located on one side in two planes with one above and at some distance from the other. Two sets of followers are mounted on a bearing shaft which is coupled with the rotating support. By means of a form-fit with the two cams, the followers provide positive movement of each extracting element over its entire revolution when the support rotates. The bearing shaft terminates above the plane in which the first cam closer to the shaft is located. The followers which correspond to the other second cam are mounted on a bridge element lying between the two cams. The bridge element is supported by spacer elements on the bearing shaft so that the spacer elements lie outside the area or path covered by the movement of the first cam.
