Device for seizing, controlling, positioning and gripping for heat-sealable semi-rigid bags which is intended for insertion into an automated self-service system

摘要

The device according to the invention permits the seizing, holding and release of semi-rigid bags, and it comprises means for unwinding the bags 11, 12, 13, for guiding and aiding opening 19, for welding 9, 17, 18, for cutting the bags 8, 17, 18, for taking and holding 2, 3, 16, means for controlling and regulating such as the processing and use of optical signals reflected by the contents in movement (amplification and shaping of signals, incrementation of a counter whose checked-off output will be compared with a time delay), it being possible for the reference values of this speed regulator to be either a switch checking off on the outputs of the counter or a potentiometer adjusting the time delay. And, finally, means for distributing electrical and pneumatic energy. IMAGE
