ABSTRACT:
The disclosure relates to a labelling mechanism for a weigh/price labelling apparatus comprising a device (10) which supplies printed self-adhesive labels on a backing strip (11) around a stripper block (12) to feed labels onto a temporary holder (13) on which a label is held by vacuum ports in the holder. A label transfer device (16) comprises a carrier (17) mounted for rotary movement on an eccentric drive mechanism (18). Rotation of the drive mechanism moves the carrier (17) from a label receiving position adjacent the holder (13) to a label delivery position for delivering a label to an article. The carrier includes a pad (42) having ports (47) to which vacuum or air pressure can be supplied to hold a label to or discharge a label from the pad.
In order to reorientate the label between the pick-up and discharge positions, the pad is mounted on a spindle (43) which is reciprocated in opposite directions by means of two pneumatically operatable piston/rack members (46) movable in bores (45) in the mounting block for the pads. The stroke of the pistons can be adjusted so that the pad can be orientated as required to suit the article to which the label is to be applied.
