TUBE STRAIGHTENING APPARATUS, TUBE DRIVE MECHANISM, TUBE STRAIGHTENING MECHANISM AND TUBE CUTTING APPARATUS

摘要

PROBLEM TO BE SOLVED: To quickly cope with a dimensional change in a tube and to improve a precision in a tube cutting length. SOLUTION: A tube drive mechanism 10 inclusive of a pair of conveyer belts 43, 62 opposing each other is used for the purpose of transporting continuous thin walled tubes T1, T2. The tube is elongated with a tube straightening mechanism 70 having a pair of rollers 86, 102 to be straightened to be straight. These are appropriately adjustable to an interval of the pair and are quickly coped with a change in tube size. The tube is cut by a tube cutting apparatus 150, at this time, the tube is accurately positioned with the optical measurement by a tube length adjustment means 120.
