Definitions

  • the present invention relates to a method and an apparatus for coil winding control of a wire-shaped element.
  • the method and apparatus in reference apply in the field of winding electric wires round reels intended for use in motor and transformer windings and the like.
  • winding apparatuses consist of a support body, generally a reel, intended to form a core for winding of a wire-shaped element.
  • the wire-shaped element which may be a cable, a wire or a ribbon of various kind, is carried by a wire-guiding system capable of guiding it in a coil-making step.
  • the reel is driven in rotation about its own axis, whereas the wire guide carries out a reciprocating motion in a direction parallel to the reel axis.
  • the rotation speed of the reel and the translation speed of the wire guide are interlocked to each other depending on the geometry and the desired wire distribution pitch.
  • each reel is then generally provided with two flanges located at the axially opposite ends thereof and intended for retaining the wire windings.
  • the wire guide stroke is directly in relation to the distance between the flanges close to which motion reversal occurs.
  • the known art has only partly obviated the above drawbacks by providing the winding apparatus with a photoelectric-cell system arranged to cause motion reversal when a wire guide reaches one flange.
  • a photoelectric cell positioned on the wire guide coaxially with the cable is capable of detecting the instant that the wire guide reaches a flange thereby causing motion reversal of same.
  • the device incorporating a single photoelectric cell appears to be critical in the case in which the reel intended for receiving the winding should have a biconical or triconical profile.
  • profiles of this typology are not provided with true flanges, but with axially opposite end regions of an inclined profile; in this case wire guide reversal is determined by interception of the inclined profile of said opposite end regions of the reel by the photoelectric cell.
  • the reversal value of the wire guide motion is controlled by the photoelectric cell after the wire has already reached the flange or the reel end region.
  • An improvement in the above mentioned photoelectric-cell system is achieved by use of two photoelectric cells mounted integrally with the wire guide at opposite positions relative to the wire guide itself along axes parallel to the reel axis.
  • the photoelectric cell located at the advancing side of the wire guide intercepts the flange some instants before said flange is reached by the wire guide. Knowing the flange position in advance at the reversal instant enables, by setting an appropriate delay time, an increase in the winding precision to be achieved close to the flanges, above all in the case of inclined flanges.
  • the delay values vary on varying of the radial sizes of the coil.
  • the photoelectric-cell intercepting system of the flanges operates by recognizing the flange due to its different radial extension relative to the coil extension.
  • an apparatus for coil winding control of a wire-shaped element has been generally identified by reference numeral 1.
  • the apparatus consists of a predetermined support body 2, or reel, generally defined by a revolution body around which the wire-shaped element 3 is wound for generating a winding 4.
  • Reel 2 as in the example shown in Fig. 1, can have a central body 5 of substantially cylindrical form and two disc-shaped flanges 6,7 of greater radial size than the cylindrical body 5 and located at opposite ends along the longitudinal axis 8 of reel 2.
  • the outer surface of the cylindrical body 5 is designed to form the coil core, whereas flanges 6, 7 hold the windings thereby enabling a better laying down of the wire-shaped element 3 at the coil ends.
  • the support body 2 can have a different geometry; in typologies more commonly used the central body can be of frustoconical shape, provided with flat flanges (conical coil) or provided with flanges of frustoconical shape as well which are identical (biconical coil) or different (triconical coil).
  • the coil could also be of a mixed type (having any profile), but in any case it will be provided with two flanges 6, 7, located at opposite positions along a longitudinal-extension axis 8 of the support body 2, intended for holding winding 4.
  • the wire-shaped element 3 such as a metal cable adapted to make windings in electric motors for example (but generally a wire, a ribbon or flexible tube of the most different typologies and sizes and for the most diversified uses) is carried by guide means 9 arranged to wind it around the support body 2.
  • the guide means 9 currently known as wire guides, are moved with a reciprocating translational motion along a direction parallel to the reel axis 8.
  • the reel is driven in rotation around its own axis 8, while the wire guide is moved with a rectilinear motion, laying down wire 2 with the desired pitch on the support body 2.
  • the apparatus further comprises detecting means 10 to detect a real profile 11 of at least one portion of winding 4.
  • This detecting means 10 is capable of stating the actual distance of one point of the profile 11 from the axis 8 of the support body 2, even during the winding procedure.
  • This means comprises an emitter 12 sending a signal 12a to winding 4 and a receiver 13 for picking up the return signal from the winding.
  • emitter 12 is of a preferably IR, laser type capable of generating a signal 12a consisting of a collimated beam and then impinging on a precise and circumscribed region of profile 11 at the point where the wire is being wound; a receiving device 13 of known and conventional type receives the return signal 12b generated by impact of signal 12a onto winding 4. More specifically, device 13 determines the distance of emitter 12 from the hit point; the geometry of the support body 2 and positioning of its axis 8 relative to the emitter being known, device 13 enables a processing unit 14 to find the radial position of said point relative to the rotation axis 8.
  • the apparatus is always provided with at least one processing unit 14 capable of defining an ideal profile 15 of the winding, comparing a portion thereof with the corresponding real profile 11 previously detected and causing a relative axial displacement between the support body 2 and guide means 9, in order to correct the real profile 11 of the detected winding portion and make it consistent with the corresponding portion of the ideal profile 15.
  • the command for the relative displacement between winding 2 and guide means 9 is obtained by the processing unit 14 by varying the reversal positions of the wire-guide motion.
  • the processing unit 14 receives the signals relating to the ideal profile 15, compares them and generates an output signal by which a power unit 16 moving the guide means 9 is controlled.
  • the detecting means 10 is mounted integrally with the wire guide and it carries out detection of the positions of profile 11 points during winding.
  • the method for coil winding control (diagrammatically shown in Fig. 3), in addition to the steps of arranging a predetermined support body (denoted by reference numeral 17) and winding the wire-shaped element around said support body for generating a winding (reference numeral 18), also involves the further step of defining an ideal profile of the winding (reference numeral 19).
  • This step 19 is accomplished by identifying at least one sampling portion 20 of the real profile 11, which portion preferably is at a central region of the winding profile, and determining the ideal profile based on the identified sampling portion 20.
  • the method provides for detecting the position of five points of the central region of the real profile.
  • the position of a central point 21 of the real profile 11 is detected, as well as the position of the respective medium points 22, 23 of each of the two halves into which the profile is divided by said central point 21 and the position of the respective medium points 24, 25 of each of the two gaps defined between the medium points 22, 23 of the halves and the central point 21 of the real profile.
  • a straight line is defined that approaches the development or shape of the real profile 11 at the central region of winding 4 and supplies an indication of the desired shape at the axially opposite end regions 26 of the coil.
  • the method in accordance with the present invention further comprises a step of detecting a real profile of at least one portion of the winding (referenced by 27 in Fig. 3); this step involves detecting of the position of a predetermined number of points spaced apart at a region of the winding according to a desired pitch so that the real portion shape 11 can be extrapolated.
  • the axially opposite end regions 26 of the profile are those much more subjected to have irregularities in the profile during the coil manufacture (see, in this connection, coil shown in Fig. 1).
  • the method provides for detection of the winding portion at at least one axial end region 26 of the winding and preferably at both axially opposite ends.
  • the method involves a step 28 of comparing the corresponding parts of the real and ideal profiles, 11 and 15 respectively.
  • the deviation parameter is an index of how much the real profile deviates from the desired shape and may consist of, for example, an area 29 defined between the ideal profile 15 of the winding portion and the corresponding portion of the real profile 11.
  • the processing unit 14 is entrusted with the task of calculating this parameter; it receives the position of the points of the end regions 26 from the detecting means 10 and, since it knows the distance between two successive points, it can calculate the area of the rectangles 30 subtended to the arc (see Fig. 2).
  • a null area means a real profile 11 coincident with the ideal profile 15.
  • the method then involves a step 31 of correcting the real profile 11 of the winding portion 4 with a corresponding portion of the ideal profile 15.
  • the correcting step 31 further comprises the sub-step of varying a time law or space law regulating said winding step 18 in order to minimize said deviation parameter.
  • a starting step (denoted by reference numeral 32 in Fig. 3) can be provided for identifying a real positioning of each flange located on the support body in order to eliminate possible tolerance errors and/or positioning errors of the support body.
  • the invention achieves important advantages.
  • the method being the object of the present invention enables a control to be carried out on the actual correctness of the coil profile, by automatically varying the winding parameters in order to eliminate profile errors or irregularities.
  • the described method and apparatus enable errors in winding, due to shape defects in the support body and/or variations in the motion reversal positions of the wire guide to be corrected without the operator's intervention, and also enable correction of errors resulting from vibrations of the support body during winding.
  • this method can be implemented in a simple manner and can be applied to all different typologies of reels used, while always ensuring a regular profile.
  • a further advantage is connected with the fact that this method and apparatus, by ensuring a regular winding without being it necessary to intercept the flanges at each cycle, enable a complete and correct control of the coil profile until complete filling of said coil.
