A CONTROL SYSTEM FOR A MACHINE FOR WINDING ELECTRICAL CABLES AND THE LIKE, AND A METHOD OF CONTROLLING THE MACHINE

摘要

The system comprises a laser light source (20) arranged so that it projects a line of light (L) which intersects the portion (C1) of the cable (C) between the cable guide (17) and the reel (8) near the point (Q) at which the cable (C) is deposited on the reel (8), and a processing and control system (30, 31) which is arranged: to determine the position of a characteristic point (P) of the intersection of the line of light (L) with the portion (C1) of the cable (C), relative to a first reference axis (x) parallel to the axis of the reel (8) and fixed to the cable guide (17); to calculate the velocity (VP) of the movement of the characteristic point (P) relative to the axis (x); to bring about a relative movement between the cable guide (17) and the reel (8) at a nominal velocity (VO) which depends upon the diameter (D) of the cable (C) and is proportional to the speed of rotation ( OMEGA ) of the reel (8) when the characteristic point (P) remains in a constant and predetermined reference position (xO) relative to the axis (x) and its velocity (VP) is substantially zero.
