PACKAGING MACHINE AND METHOD FOR ADJUSTING MULTIPLE MACHINE ELEMENTS ON A PACKAGING MACHINE

Abstract

A packing machine and a method for adjusting multiple machine elements on a packaging machine, wherein the position of each machine element is changeable by driving an assigned spindle in a rotary manner, and wherein a position measuring device by means of which the position of the assigned spindle is measurable is present on each spindle, and wherein the measurement data of the different position measuring devices are transmittable to a control.

Claims

1. A method for adjusting multiple machine elements on a packaging machine, wherein the position of each machine element is changeable by driving an assigned spindle in a rotary manner, and wherein a position measuring device by means of which the position of the assigned spindle is measurable is present on each spindle, and wherein the measurement data of the different position measuring devices are transmittable to a control, the method comprising the following method steps: a) coupling an adjusting device to a spindle, wherein the coupled spindle is drivable in a rotary manner by driving the adjusting device; b) driving the adjusting device with a predefined detection adjusting movement, wherein the spindle is adjusted along a detection adjustment path by means of the predefined detection adjusting movement; c) detecting the spindle, for which the adjustment along the detection adjustment path has been transmitted, via the control; d) determining the deviation between the measured actual value (α.sub.ist) and a predetermined target value (α.sub.soll) of the position of the detected spindle via the control; e) via the control, generating an adjustment signal for controlling the adjusting device when adjusting the detected spindle from the actual position (α.sub.ist) into the target position (α.sub.soll).

2. The method according to claim 1, wherein when driving the adjusting device with the predefined detection adjusting movement, the spindle is adjusted by a predefined angular amount in a direction of rotation in a first step and by the same angular amount in the direction of counterrotation in a second step.

3. The method according to claim 1, wherein the adjustment signal for controlling the adjusting device when adjusting the detected spindle from the actual position into the target position is automatically output by the control in a time-controlled manner after a preset time period (t.sub.2 to t.sub.3).

4. The method according to claim 1, wherein method steps a) to e) are performed for all spindles of the packaging machine which have to be adjusted in a format adjustment of the packaging to be processed.

5. The method according to claim 1, wherein the adjustment of all spindles which are to be adjusted in a format adjustment of the packaging to be processed is monitored, wherein the operation of the packaging machine is blocked until all spindles which are to be adjusted in the format adjustment of the packing to be processed are adjusted.

6. A packaging machine for performing a method according to claim 1, wherein the position of each machine element is changeable by driving an assigned spindle in a rotary manner, and wherein a position measuring device by means of which the position of the assigned spindle is measurable is present on each spindle, and wherein the measurement data of the different position measuring devices are transmittable to a control, wherein the packaging machine comprises an adjusting device which is capable of being coupled to a spindle of the packaging machine, wherein the coupled spindle is drivable in a rotary manner by driving the adjusting device, and wherein a trigger element is provided on the adjusting device, and wherein, by actuating the trigger element, driving the adjusting device with a predefined detection adjusting movement is capable of being triggered, and wherein the spindle is adjusted along a short detection adjustment path by means of the predefined detection adjusting movement.

7. The packaging machine according to claim 6, wherein the trigger element is realized in the manner of a pressure switch.

8. The packaging machine according to claim 6, wherein the adjusting device and the control exchange data via a wired data interface.

9. The packaging machine according to claim 6, wherein the adjusting device and the control exchange data via a wireless data interface.
