Abstract
Abstract A matching method and apparatus for the automatic cutting of patterned fabrics by an integrated marking and cutting system first defines matching points in each of the patterns of panels to be cut and digitizes these points so that the coordinates and respective identification codes for each of the points are recorded in a memory. Matching relationships are then defined for the matching points which unequivocally fix the position which the design must be in at each of the matching points and digitizes and records these relationships in the memory. Separation margins between the panels in their distribution are then established either automatically or interactively on the basis of the previously defined matching relationships and a vision sensor is then automatically positioned over the spread patterned fabric which is to be cut in the positions of the matching points which have been defined for each one of the panels which have been distributed for cutting. The relative design position with respect to a reference position at each of the matching point positions is then determined and a position correction obtained for each panel with respect to the position initially assigned to each one of the panels to be cut, each position correction being obtained on the basis of the positions of the pattern determined in the previous step and on the basis of the previously defined matching relationships wherein all of the panels which are to be cut are matched prior to proceeding with their cutting operation.

A matching method for the automatic cutting of patterned fabrics by an integrated marking and cutting system comprising the following steps: defining matching points in each of a plurality of patterns of panels to be cut, digitizing these matching points, and recording a set of coordinates and also a respective identification code for each of the digitized points in a memory of the system; defining matching relationships for the matching points which unequivocally fix the position which the design must be in at each of the matching points, and digitizing these relationships and recording them in the memory of the integrated marking and cutting system; establishing separation margins between the panels, either automatically or interactively, on the basis of the matching relationships which have been defined; initially assigning a position to each of the panels to be cut on a spread piece of patterned fabric and distributing said panels to the assigned positions; automatically positioning a vision sensor device over the spread patterned fabric which is to be cut, at the positions of said matching points which have been defined for each one of said panels which have been distributed; determining a relative design position with respect to a reference position at each of said matching point positions at which said vision sensor is positioned; and obtaining a position correction for each panel with respect to the initially assigned position based on said relative design position and said defined matching relationships, wherein all of said panels which are to be cut are matched prior to proceeding with their cutting operation.
