Abstract
Strand-shaped winding material is continuously supplied to a coil, whereby the position of the winding material is observed with at least one video camera, whereby the data about the wrapping obtained in this way are conducted to a computer unit that initiates a corresponding readjustment. With reference to the coil axis and as seen in radial direction, the position of the apexes of the turns is identified for at least respectively two turns of the new winding ply, and, given a deviation of these apexes from a rated value, a readjustment is implemented in the delivery of the winding material.
Claims18
A method for winding strand-shaped winding material onto a coil, wherein the winding material is continuously supplied, the position of the winding material is observed and registered by at least one video camera, and data about the winding obtained in this way are conducted to a computer unit that initiates a corresponding readjustment of the delivery of the winding material, the improvement comprising identifying, with reference to the coil axis as seen in radial direction, the position of the apexes of the turns for respectively at least two turns of the new winding ply;
- and for any given a deviation of these apexes from a rated value, implementing a readjustment in the delivery of the winding material that reduces the deviation.
An apparatus for winding strand-shaped winding material onto a coil whereby the winding material is supplied via a guide means that modifies the winding ply of the winding material on the coil so that an optimum uniform wrapping occurs, said apparatus having a video camera for the observation of the winding ply that supplies the data about the position of the winding it identifies to a computer unit, which initiates a corresponding readjustment of the guide means, the improvement comprising the apparatus having a light source that generates a light band on at least parts of the last winding ply;
- and the video camera serving the purpose of observation being arranged so that it identifies the condition of the illuminated winding ply roughly in the region of the winding-on point where the winding material meets the winding ply lying therebelow.
An apparatus for winding strand-shaped winding material onto a coil whereby the winding material is supplied via a guide means that modifies a winding ply of the winding material on the coil so that a uniform wrapping occurs, said apparatus having a video camera for the observation of the winding ply that supplies data about a position of the winding material to a computer unit, which initiates a corresponding readjustment of the guide means, the improvement comprising the apparatus having a light source that generates a light band on at least parts of a last winding ply;
- and the video camera serving the purpose of observation being arranged so that the video camera identifies a condition of the illuminated winding ply roughly in the region of a winding-on point where the winding material meets the winding ply lying therebelow, and the computer unit being of the type that identifies, with reference to a coil axis as seen in a radial direction, the position of respective apexes of at least two turns of the last winding ply, and for any given deviation of these apexes from a rated value, the computer unit implements a readjustment in the delivery of the winding material that reduces the deviation.
