Strip-shaped body cutting position adjustment method and system for cutting apparatus

A strip-shaped body cutting position adjustment method for a cutting apparatus, the method used in a system comprising:

• a strip-shaped body feeding apparatus configured to feed a strip-shaped body;
• a cutting apparatus configured to cut the fed strip-shaped body;
• a compensator roller which is provided in a strip-shaped body transport path extending from the strip-shaped body feeding apparatus to the cutting apparatus and which is supported movably for changing a length of the strip-shaped body transport path extending from the strip-shaped body feeding apparatus to the cutting apparatus;
• a register mark printed on the strip-shaped body;
• a detector which is provided in such a manner as to face the strip-shaped body transported from the compensator roller to the cutting apparatus, and which is configured to detect the register mark;
• and
• a control device that receives an output from the detector,
• the method comprising the steps of:
• finding, by the control device, a rotation phase of the cutting apparatus when the detector detects the register mark;
• finding, by the control device, a rotation phase difference by comparing, by the control device, the found rotation phase of the cutting apparatus at the time of detection of the register mark with a previously stored reference rotation phase;
• and
• moving the compensator roller in accordance with the found rotation phase difference,
• the system further comprising:
• first storage means for storing a first reference elapsed time from start of speed acceleration of the cutting apparatus at which movement of the compensator roller is started to an end of the speed acceleration;
• second storage means for storing a first moving amount of the compensator roller;
• and
• elapsed time measurement means for measuring time from the start of speed acceleration of the cutting apparatus,
• the method further comprising the steps of:
• comparing, by the control device, the elapsed time measured by the elapsed time measurement means with the first reference elapsed time stored in the first storage means;
• and
• moving the compensator roller by the first moving amount stored in the second storage means, when the elapsed time measured by the elapsed time measurement means becomes equal to the first reference elapsed time.
