Definitions

  • the invention relates to a device with a winding nozzle for winding saddle coils.
  • Saddle coils are used in cathode ray tube deflection units for the horizontal deflection of the electrons.
  • winding strands running in the direction of the electron beam direction are connected in series with one another.
  • the winding wire is usually inserted into a winding form provided with corresponding receptacles and the turns arranged in this way are later baked together to form a self-supporting saddle coil.
  • JP-A-5723451 specifies for the formation of a saddle coil that the turns are to be glued directly after application into a non-receiving inner contour of a mold.
  • a so-called bobbin is required to form the saddle coils, around which the winding wire is wound.
  • the coil former can be closed or, as illustrated in DE-2807978, can be designed to be open on one side.
  • the two known bobbins have two things in common. These are, on the one hand, the grooves arranged next to one another on the conical inner contour and running in the direction of the long axis of the coil body. Furthermore, these are the chambers arranged on the outside of the coil body, each of which is formed by two mutually parallel edges. The edges forming the end faces of the coil body each have slots through which a winding wire guided in a groove can be transferred to a chamber or a winding wire running in a chamber can be transferred to a groove.
  • DE-3011897 specifies a device for winding such winding areas, each lying on the inner and outer surface of the coil body, which has a winding nozzle which can be moved in two planes.
  • the winding nozzle with its internal winding wire is guided from its starting position at the upper edge of the coil former along the inner surface of the coil former to the lower edge and beyond that to the side to a stationary stop .
  • the winding wire is inserted into the lower edge of the bobbin. Then he threw the winding nozzle back along the inner surface of the bobbin to the top.
  • the winding wire is gripped by means of a hook and drawn to the outer surface of the coil former. Then the bobbin holder performs one Clockwise rotation. Since the winding wire is held by the hook during the rotation, the winding wire is simultaneously inserted into the upper edge (the so-called upper chamber). After the hook has released the winding wire and the winding nozzle has moved down a little, the formation of the next turn train begins in accordance with the procedure described above.
  • the device discussed in this document can also be used to form saddle coils on closed bobbins. Although saddle coils can be formed on all known bobbins by means of the known device, it is extremely cumbersome to finally form saddle coils by means of the known device. This is because an abundance of mechanical and therefore fragile work steps are required. The latter applies in particular to the work steps required to insert the winding wire into the upper chamber.
  • the invention is therefore based on the object of specifying a device for winding saddle coils on half-open bobbins by means of which saddle coils of any shape can be wound quickly and without problems.
  • FIG. 1 the device for winding the saddle coils is shown in a side view.
  • a stand 2 On a base plate 1, a stand 2 is arranged, which has a holding arm 3 and a receptacle 4 for the at its upper end Carries the bobbin of the saddle coil (not shown).
  • a device on the base plate 1 which can be moved in three mutually perpendicular planes.
  • This device has a bearing block 5 for a horizontal rod 6, the other end of which is arranged in a carriage 7.
  • the carriage 7 can slide on a further horizontal rod 8, which is arranged at right angles to the rod 6.
  • the rod 8 is connected to the base plate 1 via two bearing blocks 9.
  • a carrier 10 is slidably arranged on the rod 6 and holds a further vertical rod 11.
  • a bracket 12 can slide on this rod 11.
  • the holder 12 has a channel for the winding wire 19 (shown in dashed lines) 13, at one end of which there is an inlet nozzle 14 and at the other end of which there is a horizontal winding nozzle 15.
  • An outlet nozzle 16 is attached to the free end of the winding nozzle 15.
  • the inlet and outlet nozzles correspond to the commonly used nozzles.
  • the holder arm 3 with the receptacle 4 can rotate about the longitudinal axis of the stand 2.
  • the carriage 7 and thus the rod 6 can move along the rod 8, ie perpendicular to the plane of the drawing.
  • the carrier 10 is movable in the direction of the double arrow 17 along the rod 6.
  • the bracket 12 can be moved in the direction of the double arrow 18 along the rod 11.
  • the three movements mentioned are perpendicular to one another and thus the outlet nozzle 16 can be brought to any point in the space enclosed by the planes of movement.
  • FIG. 2 shows the top view of the device for winding the saddle coils. From this illustration, the possible movement of the carriage 7 along the rod 8 can be clearly seen and is indicated by the double arrow 23. It can also be seen that the bearing block 5 extends over the entire width of the base plate 1 and has a receptacle for the end of the rod 6 in the region of the rod 8 opposite it. The movement of the holding arm 3 with the receptacle 4 about the longitudinal axis of the stand 2 is indicated by the curved double arrow 20.
  • the coil body 21 is shown in side view and the starting position a of the winding nozzle 15 is shown.
  • the winding nozzle 15 moves out of this position in accordance with the movement arrows shown, then below the lower edge of the coil body 21 and then upwards in front of the groove to be wound.
  • the winding nozzle then moves further up and to the right up to the position labeled b above the upper edge of the coil body. From here there is a movement to the right and then down to the position labeled c.
  • the coil former 21 is shown with a partially broken edge in order to show the winding wires lying in the chamber underneath. From this figure it can also be seen that the planes of the grooves 22 and thus the planes of the later strands of the saddle coil do not run through the center 26 of the bobbin 21.
  • the winding nozzle then moves up, i.e. out of the plane of the drawing, and the bobbin 21 rotates 180 ° in the counterclockwise direction (arrow 25). At the same time, the winding nozzle moves to the left until the position shown in FIG. 4d, which is denoted by d, is reached.
  • FIG. 6 shows the path of the angled winding nozzle when winding the saddle coil.
  • the winding nozzle is in the starting position a and the angled end points upwards.
  • Position c is then approached via position b.
  • the winding nozzle rotates 180 ° clockwise about its longitudinal axis, so that the angled end points downward.
  • position e is reached via position d
  • the winding nozzle moves to the left into position f.
  • the bobbin 21 remains in the position shown in Figure 6.
  • the winding nozzle rotates clockwise about its longitudinal axis by 180 °, so that in the position h the angled end of the winding nozzle points upwards.
  • the winding nozzle then reaches position k via position i. From there, the changing nozzle moves to the right until it returns to position a, i.e. has reached its starting position. The next turn then begins winding as described above.
