Title: Method for registering origins of both driving device
Inventor: OKADA KATSUMI
IPC: B25J9/10
Filed: 1989-03-30
Abstract: PURPOSE:To surely and smoothly register the origins of both driving travel sections in a short time by allowing the driving travel sections on both sides to travel simultaneously to an origin position side and changing the speed to a low speed when the preceding driving travel section arrives at the position where the origin registration starts. CONSTITUTION:The driving travel sections 2R, 2L provided on both sides of a work are made to travel simultaneously at the high speed. The traveling speed is changed to the low speed by a detection signal when either one, for example, the driving travel section 2R arrives at the position X0+l0 where the origin registration starts. The other driving travel section 2L travels at a high speed at this time and follows up the driving travel section 2R up to the position where both the sections face each other upon lapse of a slight period of time. A limit switch 9R turns off to stop the driving travel section 2R when the driving travel section 2 R travels the distance l0. The origin coordinate position X<0> is simultaneously stored in a controller 7 R. The origin coordinate position X0 of the driving travel section 2L is written in a controller 7L when this driving travel section ends the distance X0.
