PACKAGING MACHINE HAVING A PROCESS-CONTROLLED EARLY START FUNCTION

摘要

The invention relates to a packaging machine (1), comprising a control unit (2), a plurality of measuring devices (5), and a plurality of working units (3) for different processes, wherein the control unit (2) is functionally connected to the working units (3) and to the measuring devices (5). A work cycle on the packaging machine (1) comprises at least one first functional process and a second functional process at one or at different working units (3), wherein the second functional process starts later than the first functional process. The control unit (2) is configured to carry out an early start for the second functional process of a working unit (3), when an actual process value of the preceding first functional process of the program sequence (P) of the working unit (3), or another working unit (3) has not yet reached the respective target process value (S). The control unit (2) is configured to actuate the early start of the second functional process based on an approximation method for predetermining the temporal end of the first functional process by means of a time-dependent measured variable of the first functional process detected on the working unit (3) by means of one of the measuring devices (5).
