BAND BUNDLING MACHINE AND METHOD FOR CONTROLLING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a band bundling machine wherein a good bundling can be achieved even if a soft work or a work which is easy to break is bundled. SOLUTION: There are provided a band pay-out mechanism 3 to pay out a band 1 along a guide route 2, a band tightening mechanism 4 which pulls back the band 1 to wind it around a work 36, and a band joining mechanism 5 to thermally bond a stacked portion of the band 1. A band drive roller 41 which can be driven normally and reversely to pay out or pull back the band 1 and a driven roller 43 which is pressed by the roller 41 are provided. A set input part 46 is provided to set a bundling length around the work 36 at a locating where the band 1 is wound. A servomotor 44 is provided with encoder to normally and reversely drive the roller 41. A control part 45 is provided to control the pulled back amount of the paid out band 1 based on the amount of rotational drive of the servomotor 44 corresponding to a bundle length set in the input part 46.
