METHOD AND DEVICE TOR REMOVING A RING-SHAPED LABEL FROM A PACK OF SUBSTANTIALLY IDENTICAL, ABUTTING RING-SHAPED LABELS, LABEL-TRANSFERRING DEVICE AND SYSTEM FOR PRODUCING PLASTIC INJECTION-MOULDED PRODUCTS

摘要

A device for removing a ring-shaped label from a pack of substantially identical, abutting ring-shaped labels comprises a pick-up head which is provided with a stop surface and retaining devices for holding a ring-shaped label against the stop surface. The device comprises a storage holder for accommodating the pack of ring-shaped labels. A displacement device can displace the pack of ring-shaped labels from a storage position, in which the pack of ring-shaped labels is situated at a distance from the stop surface of the pick-up head, to a discharge position, in which the pack of ring-shaped labels is pushed against the stop surface of the pick-up head by means of an outer ring-shaped label. A blast of air is delivered when the outer ring-shaped label is held against the stop surface of the pick-up head. The blast of air is directed laterally between the outer ring-shaped label and the adjacent ring-shaped label of the pack of ring-shaped labels, so that the adjacent ring-shaped label is blown off the outer ring-shaped label.
