Etikettiereinrichtung mit automatischer Höhenverstellung

摘要

A top ply labeler includes a presser foot and applicator pad which are arranged for relative movement to one another travel along a rectilinear path as the ram of an applicator cylinder is extended and retracted toward and away from the top surface of a lay-up of sheet material whereby a label carrying identification information are applied at predetermined positions. The applicator cylinder is mounted to the applicator backplate for relative vertical movement toward and away from the top ply surface to maintain the labeller at a desired elevation above the top ply. A vane carried by the pressure foot is detected by a sensor carried on the applicator pad when the pressure foot contacts the surface of a top ply. As the applicator pad continues its downward movement, the pressure foot and vane move relative to the applicator pad until such time as the vane is detected by the applicator pad sensor to apply to the label and stop the downward movement. The applicator cylinder retracts the applicator pad and pressure foot carrier. The labeller is driven in the Z-axis direction when the ram of the applicator cylinder is fully extended without the pressure foot making contact with the surface of the top ply.
