Automatic machine for feed of band roll to working machine, particularly for feed of packing material rolls

摘要

The registering device(28) of the conveyor's supervisory system(26) includes at least one analogue distance sensor(29) and sends a control signal which is in correlation with the distance recorded between the outer face(6) of the band roll(2) and the sensor. The distance sensor acts in accordance with a plane vertical to its longitudinal axis(5) and in accordance with a direction vertical to the feed path in the loading station(8). An Independent claim is included for an automatic feed machine where the conveyor system(12) has a lifting device which imparts to the band roll a translational movement along the feed path.
