Technology CPUs: Flying shears with print-mark synchronization based on gear synchronism
The technological task is based on flying shears containing 2 axes. Via a conveyor belt, axis 1 transports a material line marked with print-marks. Upon recognizing the print-mark, the speed of the shears connected to axis 2 is to be synchronized with the speed of axis 1. If both axes are synchronous, the material will have to be cut and axis 2 to be returned to its initial position.
This task has been realized by synchronizing the shears slide axis to the material line axis in the gear synchronism. The synchronism will be maintained as long as required by the processing (here cutting). Then the synchronized operation will be resolved and the shears slide axis will return to its initial position. When recognizing the next print-mark, the synchronized operation will be reactivated.
