Abstract
PURPOSE: To improve an orientation stop accuracy of a doffing bar of an automatic pipe changer and to get better shock absorption of each portion of machines by switching off the device power source when a doffing bar can be lowered by its own weight and by providing adequate braking action corresponding to lowering force of the doffing bar.
CONSTITUTION: Rotation of motor M given to Ball Screw 5 via Reducer 1 causes reciprocating movements of Pull Rod 6 and up and down movements of Doffing Bar 12 by Doffing Arm 9 and Fixed Side Arm 11. Switching off the drive power source when Doffing Bar 12 can be lowered by its own weight and giving adequate braking force to allow speed reduction of Doffing Bar 12, as well as operation of electrobrake MB by Limit Switch LS will stop Doffing Bar at a fixed position.
