Abstract
A control device for obtaining a uniform or even winding is provided for a winding machine for winding strand-shaped winding material, and includes a first measurement device which detects the position of the last winding to have been wound in each instance, a second measuring device for detecting the relative position of a spool with respect to a strand guide, and a computer for controlling the feed drive for the relative reciprocating traversing movement between the spool and the strand guide.
Claims8
In a winding machine for winding strand-shaped winding material on a spool to which the winding material is fed via a strand guide, having a feed drive for a reciprocating relative traversing movment of the spool and the strand guide along each other and having a control device for maintaining a constant run-on angle of the winding material running onto the spool for accurately laying turns of the winding material within each winding layer, the control device including a first and a second measurement means for detecting, respectively, locating of the winding material and instantaneous traversing position of said spool relative to said strand guide, the improvement wherein
- said first measurement means detects a position of a last-wound turn at a measurement point which is at a predetermined angle of rotation of the spool in front of a run-on point of the winding material onto the spool, and said control device further comprises
- computer means for receiving measurement values from said first and second measurement means and for calculating a relative position which said spool and said strand guide must reach after rotation of said spool by said predetermined angle of rotation of the spool in order to maintain said run-on angle and for commanding said relative position from the feed drive.
In a winding machine for winding strand-shaped winding material on a spool to which the winding material is fed via a strand guide, having a feed drive for a reciprocating relative traversing movement of the spool and the strand guide along each other and having a control device for maintaining a constant run-on angle of a running-on strand of the winding material running onto the spool for accurately laying turns of the winding material within each winding layer, the control device including a first and a second measurement means for detecting, respectively, location of the winding material and instantaneous traversing position of said spool relative to said strand guide, the improvement wherein
- said first measurement means is spaced at a distance in front of a run-on point of the winding material onto the spool for detecting the run-on angle of the running-on strand, said control device further comprising
- computer means for receiving measurement values from said first and second measurement means and for calculating an actual position of the run-on point and a desired position of the run-on point after a further rotation of the spool from the measurement values of said first measurement means, and wherein
- said first measurement means is a television camera which is directed tangentially to the uppermost winding and monitors the travel of the front end of the layer being wound.
