Method for operating a welding device, in particular a heat pulse-controlled and / or permanently heated foil welding and / or heat-sealing device with preselectable electronic, processor-controlled contact pressure and temperature control and device for this purpose

摘要

Method for operating a welding device (100) for welding weldable materials, in particular foils, preferably plastic foils in the form of tubes and / or bags and / or other weldable materials (e.g. internally coated aluminum and / or paper composite foils) with a first movable heating tape carrier (10) which carries a heating element and in particular with a second, immovable heating tape carrier (11) on which, for. B. a second heating element is arranged, the first movable heating tape carrier (10) being designed to be movable between an open position and a welding position by a drive of at least one positioning unit (12), should also malfunctions such as a blockage of a movable heating tape carrier (10) while take into account a traversing movement. This is achieved in that there is at least one sensor (20, 23, 24) for monitoring the movement between the open position and the welding position, which is connected to a monitoring controller (S) and outputs one or more signals to the latter if one is not -permitted operation. After a trouble-free travel into the welding position (SP), a permanent adjustment of the preselected contact pressure via the control (S) by the pressure sensors (23, 24) by means of the positioning unit (12) is also realized during the welding process.
