Title: Robot coordinate transform processing method
Inventor: KAMIMURA MITSUO
IPC: G05B19/4093
Filed: 1990-07-25
Abstract: PURPOSE:To perform work with high accuracy by finding the robot coordinate value of a designation point P setting a point nearest to the point P designated on a working area out of points defined in advance as an origin. CONSTITUTION:Assuming definition points located at a position nearest to the work coordinate value (Xo,Yo) of the designation point P as P6, P7, and P2, the nearest definition point out of the definition points is the point P6. Therefore, coordinate transform processing can be performed with the the least number of errors by finding the position of the designation point P setting the point P6 as the origin even when the distortion of coordinate exists in a triangular area. In other words, the robot coordinate value of the designation point P can be given as the vector sum of a vector P setting the point P6 as the origin and a vector PP6 connecting the original position of the robot coordinate to the point P6. Thereby, it is possible to perform the coordinate transform processing with the least number of errors, and to inexpensively obtain a robot operated with high accuracy.

Abstract: PURPOSE:To prevent generation of winding slippage, winding strain and a wrinkle inside a roll by positioning a contact part of a touch roll between embossing parts on both sides in the lateral direction substantially, in a winding device of a web having the embossing parts on both sides in the axial direction. CONSTITUTION:In a touch roll winding method, where a touch roll 2 is pressed to a winding core 3 side by a cylinder 4 so as to prevent entrainment of air in a process of winding a film 1 around the winding core 3 while the winding core 3 shaft-supported by shaft bearings 5 is being rotated, the touch roll 2 is contracted in length and pressed to only a portion between embossing parts E, E of the film 1 to conduct winding. In case the touch roll 2 having right- angled end edges is installed in full length between the embossing parts E, E, force concentrated to the end edges of the touch roll 2 causes scratches on the film 1, so that the touch roll 2 having end edges each with a radius of curvature R is employed. Since the touch roll 2 is pressed to the portion between the embossing parts E, E from start to finish of winding, winding slippage due to air entrainment, winding strain and a wrinkle inside a roll can be eliminated.
