SYSTEM FOR COMPUTER CONTROLLED LABELLING MACHINE

摘要

A system 150) includes a labeling machine (52) and a digital data processing system (54) connected to the labeling machine (52). A cutter (56) of the labeling machine (52) has a shaft 158) with a mark (60), which is sensed by a sensor (62). The sensor (62) supplies shaft (58) information on line (64) to digital data processing system (54). The digital data processing system (54) supplies control signals on line (64) to feed roll 166) stepper motor (67). The digital data processing means (54) is also connected to an optical sensor (76) by line (78). The optical sensor (76) senses the position of position mark (74) on the labels (70), which is correlated with the position of shaft (58) in order to feed the labels (70) to the cutter (56) at the proper rate so that the labels (70) are always cut at the kerf (72) between each label (70).
