Title: Conveying system in plastic film bag prodn. - detects records and automatically corrects effects of film slippage due to frictional drive
Inventor: KUHN ROLAND
IPC: B31B19/74
Filed: 1990-11-22
Abstract: Tubing is conveyed to a tool which divides the tubing into individual bags. The initial lay-flat longitudinally welded tubing is fed by an electric motor-driven device by friction to the tool concerned; the motor is adjusted by a signal from a regulator to which a target value has already been set for the distance moved by the bag from the angle of rotation of the motor, the actual value measured by a sensor; that actual value is fed back into the regulator to deviate for the adjustment (sic). The path of the film before the tubing is produced is measured by a detector; its value is also fed back to a controller where it is compared with a target value; any difference (due to slippage) in the distances moved by the lay-flat film and tubing is used to automatically correct the original target value of the regulator and also for recording machine data; the process can also be used to detect and display tendency of the film conveying system to alter over a long period, so that it can provide an early warning for use w.r.t. maintenance of the machine.       ADVANTAGE - Corrects the effects of slippage over prolonged periods (which effects are unavoidable). (Dwg.0/1)
