The common abnormality of the rewinding machine is that the length of the core tube is correct. After the core tube is lowered to the front track, the trolley does not push the core tube to the corresponding position in the rear section. Abnormal reason: unknown (no abnormality in instrument control inspection), solution: manually load the tube in this batch, change the knife online, change the order of layout, or change the width to ±1-2mm (usually the latter is used, which is convenient for the core tube operator), then reset, and the next batch will be automatically loaded.
Generally, you can change the knife online once. This class has tried to change the knife online three times at most. The last one used it normally. It is suspected that it may be a problem with the program.

The second common abnormality of the rewinding machine is that the knife is changed correctly, the core tube has reached the ready position, and the induction limit also senses that there is a core tube, but it does not start to automatically lower the tube. Solution: reset, manually load the tube in this batch, change the knife online, when the knife is successfully manually installed, check whether the limit near the position of the push tube is disturbed by the damaged paper, after checking OK, drive, accelerate and then reset, automatic, It should be fine.
The operator loaded the tube too fast and did not pay attention. In the case of a tube in the track, the data was reset and cleared, and the next batch of core tubes was automatically generated, which caused the motor protection alarm of the push tube trolley. Don't worry, after unloading the paper, take out all the core tubes in the track, and manually drive the push tube trolley to the initial position on the inner touch screen, and the abnormality will be released.
