Several specific examples are given below:

example one

Small-angle cutting machine:

basic setting data: the current angle ActualAngle is 17 degrees, the set angle SetAngle is 24 degrees, the platform radius PlatLength is 1800mm, the cord width MaterialWidth is 1200mm, the left distance EndLength between the material point after retreating to the position and the platform edge is 800mm, the single distance SingleLength after retreating and advancing is 600mm, the maximum stroke MaxLength of the delivered magnetic beam is 1500mm, and the long pulse unit distance PulseLength is 17.5 mm. The single advancing and retreating distance is set to ensure that the curtain cloth is not folded due to the fluctuation of the curtain cloth caused by overlarge passive pushing resistance.

The control system analyzes and calculates the data according to the set data to obtain the total movement distance TotalLength which is materialWidth/Tan (actual Angle) 0.5+ PlatLength-EndLength which is 2962 mm.

The method comprises the following steps:

1. the magnetic beam is lifted to the rearmost confirmation reference position;

2. the magnetic beam is lifted to advance, and the starting movement single distance is recorded;

3. the magnetic beam falls down to suck the materials and then retreats to the rearmost end;

4. repeating the steps 2 and 3 when the remaining moving distance is larger than the single distance, and otherwise, performing the step 5;

5. the magnetic beam is lifted and the starting movement remaining distance is recorded;

6. the magnetic beam falls down to suck the materials and then retreats to the rearmost end;

7. guiding the automatic swing angle;

8. after the swing angle is finished, the magnetic beam falls down to suck materials and moves to the foremost end;

9. the magnetic beam is lifted to retreat, and the starting movement single distance is recorded;

10. the magnetic beam falls down to suck materials and moves to the foremost end;

11. repeating steps 9 and 10 when the remaining moving distance is larger than the single distance, and otherwise, performing step 12;

12. the magnetic beam is lifted up and retreated to record the starting movement remaining distance;

13. the magnetic beam falls down to suck materials and moves to the foremost end, and specification changing is completed.

In each step, the magnetic beam is a main action part for driving the curtain cloth to move by the cloth transfer mechanism. And (1) step (6) is a specific process that the cord fabric is sucked by the cord fabric delivery mechanism and moves backwards to return the cord fabric, and the unwinding mechanism correspondingly performs winding and unwinding actions in the process. And 8-13, namely, a specific process of leading the cord fabric by the forward movement of the cord fabric sucked by the cloth delivering mechanism, wherein the unwinding mechanism correspondingly performs winding and unwinding actions.

The control system analyzes and calculates the data according to the set data to obtain the total movement distance TotalLength (materialWidth)/Tan (actual Angle) 0.5+ PlatLength-EndLength (1580 mm).
