DEEP DRAW PACKAGING MACHINE AND METHOD FOR CONTROLLING A FILM PUNCH

摘要

The invention concerns a deep-drawing machine (1) with a moulding station (2) for deep-drawing of moulds into a film rail (8, 10),a filling line (12) for filling products into the mills, a sealing station (3) for sealing the mills, a chain guide (13) for conducting a transport chain (11) for the rolling stock (8, 10),a cross-sectional device (4) for cutting through the foil track (8, 10) in a direction perpendicular to the direction of transport (R);a longitudinal cutting device (5) for cutting through the foil track (8, 10) in the direction of transport (R);and a control device (19) to control processes occurring on the deep-drawing machine (1), with the cross-cutting device (4) a film dance (15),includes a control drive (19) controlled by the control device (16) to close and open the film dance (15) and a recording unit (17) connected to the control device (19) and having at least one sensor (18) trained to close and open the film dance (D) one at the film dance (15)recording the force flow (K) associated with opening and closing, with the control device (19) designed to detect temporary bursts of force (E) recorded by means of the sensor (18) during a tendency increase in force (Z) in the course of force (K);which detects separation of the film track (8, 10) by means of a knife (22) of the film dance (15) to perform a dynamic adjustment of a control signal (x) to open and/or close the film dance (15) depending on this.The invention also concerns a process for the controlled separation of a film track (8, 10).
