LABELLING UNIT FOR APPLYING A LABEL ONTO AN ARTICLE

摘要

A labelling unit comprises support means and a receiving member adapted to carry an article to be labelled and to receive a label, and supported by the support means in a translational and rotational manner with respect to an axis. The receiving member is movable along an axis between a raised position, in which it axially protrudes from the support means and is adapted to receive the article on its top portion and the label wrapped around its lateral wall, and a retracted position, in which it is housed within the support means so as to permit insertion of the article into the label welded in an endless configuration. The lateral wall of the receiving member comprises first suction means cooperating in use with a leading edge of the label, and second suction means cooperating in use with a remaining part of the label.

主权项

1. A labelling unit for applying a label onto an article; said labelling unit comprising:
support means; and a receiving member adapted to carry said article and to receive said label, and supported by said support means in a translational and rotational manner with respect to a unit axis; wherein said receiving member is movable along said unit axis between:
a raised position, in which said receiving member axially protrudes from said support means, carries said article on a top portion and is adapted to receive said label wrapped around a lateral wall; anda retracted position, in which said receiving member is housed within said support means so as to permit insertion of said article into the label welded in an endless or sleeve configuration; wherein said lateral wall of said receiving member comprises first suction means cooperating in use with a leading edge of the label during wrapping thereof around the receiving member, and second suction means cooperating in use with a remaining part of the label during said wrapping; wherein, during wrapping of said label around said receiving member, said first suction means are activated prior to said second suction means to maximize the retention force on said leading edge of said label at the beginning of the transfer of the latter onto said receiving member.
