Definitions

  • the present invention relates to a device for winding electrical coils with closed cores, according to the preamble of claim 1 and is based on US-A-2 962 235.
  • the present invention has for its object to provide a device which is suitable for winding extremely small core coils in the order of magnitude of about 3 mm core outer diameter with a core opening up to about 0.35 mm. It is a further object of the invention to design the device in such a way that an automatic workflow is ensured from the wire feed to the fully wound core coil.
  • the advantage of the invention can be seen in particular in the fact that the coil former is fixed on the coil former receptacle during the entire winding process of the core coil and that the winding wire is constantly held and guided during the winding of the core coil by the total length of the wire section measured for each winding in the Wire holder is clamped, the distance between the wire holder in the winding position and the separating device in each case corresponding to a wire section required for the winding, and on the other hand for each individual winding the winding wire in one of the four wire tensioners is only lightly pressed by an adjustable spring, so that the wire can slip slightly after each turn.
  • the wire is placed on the coil former by means of the catch hook before the rotation of the wire tensioners, whereupon the wire tensioners rotate by 270 ° and one turn is thus placed on the coil former.
  • a support 1 is arranged on a foundation plate 9, for example as a rectangular, rotatable turret, which is designed to be rotatable about the axis of rotation X by 180 °.
  • a turret head 1 Arranged on the turret head 1 are two bobbin receptacles 11, 11 ', each of which has a wire holder 12, 12', the one bobbin receptacle 11 'with the wire holder 12' in the region of a coil magazine 52, and the second bobbin holder 11 with the wire holder 12 is in the winding position in the area of a wire feed device 4.
  • the coil magazine 52 is a component of a loading and unloading station 5 which has a transfer device 51.
  • the wire feed device 4 consists of a supply spool 41 for a winding wire 6, a wire guide 42 and a wire brake 43.
  • the winding unit 3 consists of a winding head 31 with four wire tensioners 32a, 32b, 32c, 32d, each of which has an adjustable spring 33 for clamping the winding wire 6 exhibit.
  • the winding head 31, together with the wire tensioners 32a, 32b, 32c, 32d, is driven by a winding head drive 34 and can be raised and lowered vertically by an adjusting device 35.
  • the wire pull-in device 2 consists of a catch hook 22 (as shown in FIGS. 3, 3 ', 3 ") which is guided horizontally in the positions 22-1, 22-2, 22-3, 22-4 in a guide 21 and which holds the wire tensioner 32a, 32b, 32c, 32d and the core opening 71 of the bobbin 7 'is designed to be penetrable, the free wire end 62 of the wire section in the form of a wire loop 61 being pulled through one of the wire tensioners 32a, 32b, 32c, 32d and the core opening 71
  • Wire tensioners 32a, 32b, 32c, 32d are designed to be rotatable clockwise and counterclockwise with the winding head 31, with a cyclical rotary movement of the wire tensioners 32a, 32b, 32c, 32d in each case by 270 ° via the winding positions A, B, C, D etc.
  • the individual working positions, in particular the catch hook 22 and the wire tensioner 32a, 32b, 32c, 32d, can be preselected in a known manner by a controlled drive device 10 of the winding device.
  • the catch hook (shown in dashed lines) arranged in the starting position 22-1 immediately outside the wire tensioner 32a in the winding position A is shifted horizontally to the still unwound bobbin 7 'in such a way that it first opens the wire tensioner 32a and then the core opening 71 of the bobbin 7'. penetrates, and with the hook directed downwards lies above the tensioned winding wire 6 according to FIG. 3 "(shown in broken lines) in position 22-2. Subsequently, the catch hook 22 is slightly moved to position 22-3 (in FIG .3 "also shown in broken lines), whereby the winding wire 6 stretched between the wire holders 12, 12 'is caught and held in the hook directly in front of the core opening 71.
  • the winding wire 6 held in this way for the coil former 7 ′ is now separated by the separating device 13.
  • the separating device 13 can be designed such that two mutually adjustable separating points 13, 13 'are provided in order to be able to set the length of the required wire sections for the coil former 7' to be wound and the length of the winding end of the finished core coil 7 as desired. In the latter case, the piece of wire between the separation points 13, 13 ' would be eliminated as waste.
  • the catch hook 22 is withdrawn again from the position 22-3 with the winding wire 6, so that the wire section with the free wire end 62 in the form of a wire loop 61 first of all the core opening 71 of the coil former 7 '.
  • the winding head 31 rotates with the four wire tensioners 32a, 32b, 32c, 32d counterclockwise by 270 ° (in the direction of the arrow with the arrow fully drawn), the wire section being held in the wire tensioner 32a to form the first turn 81 while the other wire tensioners 32b, 32c, 32d turn empty.
  • the catch hook 22 is moved from the position 22-4 (shown in broken lines) to the starting position 22-1 of the winding position A.
  • the wire tensioners 32a, 32b, 32c, 32d according to FIGS. 3a, 3a 'rotate from positions A, B, C, D (shown in broken lines) to the intermediate positions (with solid lines), the wire tensioner 32a with the held one Wire section after 270 ° rotation of the winding head 31 is brought into position D according to FIGS. 3b, 3b ', with which a full turn 81 was placed on the first leg 72 of the coil former 7'.
  • the one in the floor plan 3a 'shown in FIG. 3a' wire tensioners 32a, 32b, 32c, 32d rotated counterclockwise by 45 ° into the intermediate positions have been omitted for the sake of clarity.
  • the second and subsequent turns 81 of the first leg 72 of the coil former 7 ' are wound analogously to the previously described functional sequence according to FIGS. 3, 3', 3 "to 3c, 3c ', only with the difference that the winding wire 6 is already in the
  • the catch hook 22 is pushed back and forth from its starting position by the following open wire tensioner 32b located in the winding position A and the core opening 71, as already described, whereby the winding wire 6.
  • the wire tensioner 32a which is located in position D when wound in a counterclockwise direction or in position B when wound in a clockwise direction, is then opened again.
  • the winding of the second leg 73 takes place by reversing the winding direction — in the present case clockwise — in order to establish a wire connection between the two legs 72, 73 of the bobbin 7 ′ within the core opening 71 avoid, a vertical displacement of the wire tensioners 32a, 32b, 32c, 32d of the winding head 31 takes place, so that the connecting wire from the first to the second leg 72, 73 is not guided over the core opening 71, but at the edge of the core opening 71.
  • the adjusting device 35 In order to be able to lay the turns 81 approximately in layers, the adjusting device 35 according to FIG. 1 is provided, which after each turn 81 or continuously shifts the winding head 31 with the wire tensioners 32a, 32b, 32c, 32d slightly vertically, for example on the first leg 72 of the bobbin 7 'from bottom to top and on the second leg 73 from top to bottom. Depending on the number of turns, the wire tensioners 32a, 32b, 32c, 32d are each adjusted by 90 ° clockwise or counterclockwise.
  • the core coil 7 is formed from several, for example from two individual, independent windings on each leg 72, 73 of the coil former 7 ', the winding of the coil former 7' can be carried out on two winding devices 2, 3 arranged on a support 1 designed, for example, as a rotary table respectively.
