Definitions

  • the invention relates to a coil winding device with a clamping device for the coil support body and with a wire feed device.
  • a known coil winding device - DE-B-1914 946 - is equipped with a turret table on which the winding mandrels for the production of wire windings are arranged.
  • the drive shaft which is constantly coupled to a drive device, can be displaced relative to the turret table and can be brought into a drive connection with the winding mandrel.
  • two cooperating wire clamping jaws which are displaceable in the axial direction relative to one another are assigned to the drive shaft.
  • the displacement arrangement for the drive shaft is actuated, the wire is clamped by means of these wire clamping jaws. Clamped to produce the desired wire jaws.
  • the winding mandrels in the turret table are axially adjustable to produce the desired wire windings.
  • This construction is very complex to manufacture, since the drive shaft for coupling with the coil support bodies must be displaced in the longitudinal direction of the shaft.
  • the coil support body is shifted both in its longitudinal direction and set in rotation about its own axis, whereby additional control devices are required.
  • FIG. 1 Another known coil winding machine - DE-A-26 32 671 - has a clamping device for a plurality of coil support bodies of electrical coils.
  • the clamping device consists of two collets which are spaced apart from one another in the longitudinal direction of the bobbin and with which the opposite ends of the bobbin are gripped.
  • the collets coupled to the rotary drive can be adjusted relative to the other collets facing the other ends of the coil support bodies along an axis running transversely to the longitudinal direction of the coil support bodies in order to engage different ones of the coil support bodies arranged in a row next to one another with the opposing further collets.
  • coil support bodies to be wound and the associated wire feed devices are adjustably mounted along several axes relative to the coil support bodies. Due to the one-sided rotation drive of the coil support body, there is often twisting during the winding process, as a result of which the quality of the applied winding and of the coil support body itself is adversely affected.
  • the present invention has for its object to provide a coil winding device of the type mentioned, with which wires with different wire sizes can be processed in succession and in which the pitch and the number of turns of the individual coils can be freely controlled in wide ranges.
  • this coil winding device it should be possible with this coil winding device to apply windings to rectangular coil carriers and to process wires with angular cross sections.
  • the pitch of the coil windings can be changed continuously in large areas without influencing the rotary drive for the coil support body.
  • This also opens up the possibility of carrying out separate return and lifting movements for positioning the wire on the coil support body when winding wires or for winding a coil support body with angular cross sections.
  • the separate arrangement for generating the winding gradients enables rapid changeover to different types of wire, and the accessibility and maintenance of the machine are improved or simplified.
  • the use of two separate collets enables quick adjustment to bobbins with different lengths. Due to the separate collets, the coil support body can be held with one collet, while the wire can be gripped with the coil support body at the beginning of the winding process with the second collet.
  • Another embodiment of the invention describes claim 3, whereby the threading of the beginning of the wire at the beginning of the winding process in the collet facilitates and thus simultaneous clamping of the wire to be wound and the coil support body is achieved with a collet.
  • This embodiment variant combines the advantages of a fixed-mounted rotary drive with the advantages of using one of the collets as a feed device for the coil support bodies.
  • the use of highly resilient and very precise gear or rotating ring arrangements is made possible in a surprisingly simple manner with the adjustable collet by assigning the locking device for the toothed ring. This ensures that after a movement of the collet, it can be brought back into engagement with the rotary drive in a trouble-free manner and in exactly the same position as the fixed collet. This ensures high winding accuracy and prevents the coil former from being overstressed from the start due to a twisted arrangement of the collets.
  • Another embodiment is disclosed in claim 5.
  • the use of the swiveling guide arm allows, especially in connection with the wire deflection roller, a gentle guiding of the wire, so that even thin wires can be wound up perfectly on angular bobbins.
  • the fixing of the guide arm surprisingly achieves an exact positioning of the start of the wire for threading into the collet without this hindering the winding process due to the guiding of the wire lying directly in front of the coil support body, since the guide arm can be freely pivoted during the winding process.
  • Another advantage is an embodiment according to claim 6.
  • the use of braking devices enables a uniform wire removal speed. Deformations in the wire during the winding process or in the event of brief stoppages for positioning the wire during the winding process are avoided. This prevents overstressing of the wire material as well as unwanted kinking of the same.
  • the functional reliability of the coil winding device is increased. It is advantageous if the braking force of the magazine is regulated as a function of the wire weight in the magazine, since undesirably high tensile stresses are therefore present, especially when there is only a small amount of wire in the magazine and at the same time excessive strain on the wire is avoided.
  • An embodiment variant according to claim 7 is also possible within the scope of the invention.
  • By assigning an additional wire straightening device between the wire feed device and the wire magazine it is also possible to compensate for stronger deformations in the longitudinal direction of the wire. This makes it possible to use the coil winding machine to process not only thin, flexible, but also very stiff wires, for example with a square, rectangular or other polygonal cross section.
  • the straightening jaws of the straightening stations can be used as additional braking stations for evenly decelerating the wire band during stop movements when using strong wires.
  • An embodiment according to claim 8 is also advantageous. This ensures that the wires are cut correctly since the wire is already aligned in the cutting area.
  • An embodiment according to claim 9 is also particularly advantageous. These measures ensure that the wire feed device can simultaneously be used to push the wire at the end of a winding process, to position the start of the wire for a further winding process or to thread the start of the wire into the collet. This makes it possible to position the aligned beginning of the wire in the new starting position for the next winding process without arranging a further additional device.
  • An embodiment according to claim 10 is also advantageous, as a result of which both the wire and the coil support body can be gripped simultaneously.
  • Winding down, especially with rectangular coils. can be achieved by the subsequent free movement of the guide arm can.
  • FIG. 1 shows a coil winding device 1 according to the invention.
  • This comprises a machine table 2, on which a rotary drive 3 for collets 4, a clamping device 6 is attached.
  • the collet 4 is assigned to the machine table 2 and consists of two gripper jaws 7, 8.

This adjustability of the distance between the guide jaws 29, 30 enables adjustment to different wire thicknesses.
  • the guide jaws 29, 30 with the guide 31 are fastened on a slide 34 which is mounted so as to be displaceable along a guide track 35 by means of a feed drive 36 in the feed direction of the wire - arrow 37.

  • the wire magazine 28 is assigned a braking device 39, the effect of which is controlled as a function of the wire weight in the magazine 28.
  • the wire is mounted on a mounting plate 40, which is rotatably mounted about an axis of rotation 41.
  • a friction clutch 42 which forms the braking device 39, is arranged under the receiving plate 40.
