A servo controlled labeling apparatus, comprises a conveyor for supplying a plurality of articles through a conveyor guide, an active star wheel having a plurality of arms to form a plurality of pockets, a rotating roller star drum having a plurality of rollers and a vacuum drum rotatable about a drum axis positioned opposite the rotating roller star drum. A servomechanism controls the infeed acceleration of the active star wheel and the speed of each of the plurality of articles. Each of the plurality of articles fed through the conveyor goes past the active star wheel, then between at least two of the plurality of rollers of the rotating roller star drum and the vacuum drum, which spins each of the plurality of articles into the labeling zone by the speeding up of the rotating roller star drum and the slowing down of the vacuum drum for the application of the label thereto. |

1. A servo controlled labeling apparatus, comprising:
a conveyor for supplying a plurality of articles into a labeling zone through a conveyor guide, the conveyor guide configured to constrain the plurality of articles passing there through; an active star wheel having a plurality of arms to form a plurality of pockets, each of the plurality of pockets adaptable to receive each of the plurality of articles through the conveyor, the active star wheel adaptable to rotate about a central axis; a rotating roller star drum having a plurality of rollers, each of the plurality of rollers includes a plurality of flexible discs arranged in a stacked manner, the rotating roller star drum employed to guide each of the plurality of articles from the active star wheel to the labeling zone utilizing at least two of the plurality of rollers; a vacuum drum rotatable about a drum axis and positioned opposite the rotating roller star drum, the vacuum drum rotates at a speed higher than the speed of the rotating roller star drum and holds a label to be attached to each of the plurality of articles coming into the labeling zone; and a servo mechanism controlled by a programmed control panel with a user machine interface, the servo mechanism controls the infeed acceleration of the active star wheel and the speed of each of the plurality of articles fed through the conveyor; whereby the servo mechanism controls the infeed acceleration of the active star wheel and each of the plurality of articles goes past the active star wheel, then between at least two of the plurality of rollers of the rotating roller star drum and the vacuum drum, which spins each of the plurality of articles into the labeling zone by the speeding up of the rotating roller star drum and the slowing down of the vacuum drum for the application of the label thereto. |
