PCT No. PCT/GB95/02271 Sec. 371 Date May 30, 1997 Sec. 102(e) Date May 30, 1997 PCT Filed Sep. 22, 1995 PCT Pub. No. WO96/09212 PCT Pub. Date Mar. 28, 1996An apparatus for applying adhesive labels to the rear of articles on a moving conveyor. Two arms are mounted on a gantry spanning the conveyor. Each arm has an inner arm portion mounted on a shaft which is rotated by a motor and transmission, always in the same direction, under the control of a computer having an input from a sensor for detecting the rear edge of each article. Each arm has an outer arm portion pivotably connected to the inner arm portion and urged to a generally straight position by a torsion spring. Each outer arm carries a label-applying pad which is extended by an actuator to collect a label from a printer above the gantry and then retracted as the arm rotates in response to detection of a package. |
