<p>PROBLEM TO BE SOLVED: To reduce cost and to improve productivity by quickening a clamp opening time and shortening a tact time in case of necessitating safety measures and repositioning in a pneumatic failure or power source failure. SOLUTION: In this work clamp devices 25A, 25B and a first and second pneumatic circuits 53, 55 of repositioning devices 27A, 27B, a pressurizing operation of a first pneumatic cylinders 65A, 65B provided in the repositioning devices 27A, 27B is inked with an opening operation of the upper jaws 41A, 41B of a second pneumatic cylinders 37A, 37B for opening and closing the upper jaws 41A, 41B provided in the work clamp devices 25A, 25B. Thus, costs are reduced and productivity is improved by quickening a clamp opening time and shortening a tact time in the case of repositioning.</p> |
