Definitions

  • the invention relates to a device for winding a coil core with a wire for the production of electrical coils according to claim 1.
  • winding devices are known in which the coil cores are mounted with the aid of a spindle arranged centrally on the rotation table.
  • the spindle extends through a central passage opening in the coil core and is accommodated in a separable bearing in its upper end region protruding from the coil core.
  • a slide is provided on the spindle, which is pushed between the through-opening in the coil core and the spindle, so that the coil core is braced in the upper end area with the spindle.
  • the upper spindle bearing In order to be able to remove the coil core from the winding device, the upper spindle bearing must first be divided and pivoted to the side; then the spreader fastener must be removed so that the coil core can be pulled upwards from the spindle.
  • the particular disadvantage here is that when lifting coils stored in this way, the coil core has to be pulled off via the spindle, so that the coil core has to be lifted relatively high in order to be able to be removed from the winding device. Due to the considerable lifting height of the heavy coil, there is an increased risk of injury for the operator of the device or for other people in the vicinity of the device, in particular if the carrying cable or the like breaks.
  • removing the finished coil from such winding devices with a spindle for supporting the coil core requires special coil lifting devices. Such winding devices are therefore structurally complex and also expensive.
  • the aim of the present invention is therefore to create a device of the type mentioned in the introduction, in which the coil core is reliably supported during winding, but removal from the winding device is comparatively simple compared to known devices;
  • the aim here is to reduce the risk of injury to an operator of the device or other people in the vicinity of the device, particularly when removing the finished coil with a lifting device.
  • this is achieved in that the holding arm of the holding device can be pivoted between a winding position and a rest or changing position.
  • the bearing element Due to the spindle-free mounting with the help of a bearing element arranged on a holding arm, which, as a counter bearing to the rotary table, accommodates the coil core at the end of the coil core facing away from the rotary table, with the holding arm being pivotable, the bearing element can easily be moved to a rest position after a coil has been completed. or change position are pivoted, so that the finished wound coil can be easily lifted from the rotary table.
  • no lifting above the height of a spool spindle extending beyond the total height of the spool is necessary. As a result, the risk of injury to the operator of the device or to other people in the vicinity of the device as a result of the finished coil can be reduced.
  • conventional lifting devices can also be used and coil cores with different dimensions can be stored in a simple manner using the same bearing element, so that the overall production costs are reduced.
  • a new coil core can be easily placed on the rotary plate from above with the aid of a lifting device.
  • the holding arm can be pivoted about an axis arranged parallel to the axis of the coil core.
  • the holding arm is arranged in a height-adjustable manner according to the invention.
  • the holding arm is, according to the invention, optionally rotatable or non-rotatable with the aid of a locking device.
  • the arm can be mounted in a height-adjustable or pivotable manner in a simple manner if the holding arm is arranged on a substantially vertical post.
  • the upright according to the invention has an inner base part over which a sleeve part carrying the holding arm is placed.
  • the holding arm is mounted on the sleeve part in a height-adjustable and non-rotatable manner according to the invention.
  • the sleeve part can be adjusted in height relative to the base part by means of a screw device.
  • sleeve part is arranged in a rotationally fixed manner in its lowermost screwed-in position, preferably via an expanding attachment, a rotationally fixed arrangement of the sleeve part and thus also of the holding arm arranged in a rotationally fixed manner on the sleeve part can be achieved in a simple manner.
  • the bearing element has a housing which is arranged in a rotationally fixed manner on the holding arm and in which an intermediate part which can be vertically displaced against a spring force is arranged in a rotationally fixed manner.
  • a bearing in particular a ball bearing, is accommodated in the intermediate part, on which a fastening part is rotatably mounted.
  • a flange is provided on the fastening part for receiving a connecting part having the conical projection, different connecting parts can be fastened to the fastening part in a simple manner, so that a respective adaptation to the coil core, in particular to the dimension of the central recess or Through hole of the coil core can be achieved.
  • the rotary disk has a quill in the center, which is accommodated in a central recess of the coil core when the coil core is in the fitted position.
  • a winding device 1 in which two rotation or coil plates 2 are provided, on each of which a coil core 3 is accommodated, wherein in 1 the coil core 3 arranged on the left in the view is being wound with a wire.
  • a holding device 4 with a holding arm 5 is provided in each case as an abutment to the rotary plate 2, at the freely projecting end of which a bearing element 6 is arranged in each case.
  • the holding arm 5 can be connected to the bearing element 6 via a post 8, to which the holding arm 5 is attached, between the in 1 shown winding position and in 2 rest or changing position shown are pivoted.
  • a coil core 3 that is still empty can thus be placed on the rotary plate 2 in a simple manner, or a completed coil can be removed with a conventional lifting device after the coil core 3 has been wound with the wire 4 .
  • the post 8 is pivotably mounted in a base 9 of the device, with the post 8 being able to be arranged in the base 9 in a rotationally fixed manner via a locking device 10 .
  • the upright 8 carrying the holding arm 5 is shown in detail.
  • the upright 8 has an inner base part 11 over which a sleeve part 12 is slipped, on which the holding arm 5 can be fastened with the aid of a fastening sleeve 13 and screws 13'.
  • a linear guide 14 is provided here, so that the holding arm 5 is arranged on the sleeve part 12 in a height-adjustable but non-rotatable manner.
  • the sleeve part 12 is in the in Figure 3a shown lowermost position in its lower end area 15 spread with an engagement part 9 'of the base 9 (cf. 4 ), so that the sleeve part 12 is arranged in a rotationally fixed manner relative to the inner base part 11 .
  • the sleeve part 12 is released from its non-rotatably arranged, spread position with the aid of the locking device 10, which has a lever arm 16.
  • a threaded part 16' screwed into a receptacle 11' of the inner base part 11 is connected to the lever arm 16, via which the sleeve part 12 can be lifted out of its lower position with the aid of a nut 17 and transferred into the upper position released from the splayed position can (cf. Figure 3b ).
  • the transfer to the raised position is facilitated by means of a spring 18 which is arranged between the inner base part 11 and the sleeve part 12.
  • the coil core 3 is shown in its winding position, whereby it can be seen that the coil core 3 is rotatably mounted on the rotary plate 2 and the bearing element 6 arranged on the holding arm 5 as a counter bearing to the rotary plate 2 .
  • a quill 19 is provided centrally on the rotation plate 2 and is accommodated in a central recess 3 ′ of the coil core 3 .
  • the quill 19 extends - unlike known spindles - over a very small section of the overall height of the coil core 3, in any case less than half the height of the coil core 3.
  • the bearing element 6 also has a conically tapering connecting part 20, which is in the central recess 3' of the coil core 3 in the in 4 shown winding position is included.
  • the sleeve part 12 of the post 8 is first fixed by turning the lever arm 16 of the locking device 10 in the direction of the arrow 21, then the screws 13' of the sleeve 13 of the holding arm 5 are loosened so that the holding arm 5 can be pushed down in the direction of the arrow 22, until the conical connecting part 20 engages in the central recess 3' of the coil core 3.
  • the sleeve part 13 is released by rotating the lever arm 16 of the locking device 10 in the direction of the arrow 21'.
  • the holding arm 5 is then pushed down again in the direction of the arrow 22 and the screws 13' of the fastening sleeve 13 are then tightened. Finally, the holding arm 5 is moved again in the direction of the arrow 21 for the non-rotatable fixing of the sleeve part 12 and for bracing the coil core 3 between the rotary plate 2 and the bearing element 6 provided as a counter bearing (cf. Figure 5c ) twisted.
  • the bearing element 6 is shown in detail, it being evident that a housing 23 is fastened to the holding arm 5 via a screw connection.
  • a vertically displaceable intermediate part 24 is received in the housing 23 in a rotationally fixed manner and can be displaced counter to the force of cup springs 25 which are arranged between the intermediate part 24 and the base part 23 .
  • a ball bearing 26 is accommodated in the intermediate part 23, via which a fastening part 27 with an end flange 27' is rotatably mounted.
  • the fastening part 27 here has a central recess for receiving a centering bolt 20' of the connecting part 20, which has a conical projection 20'' which engages in the central recess 3' of the coil core 3 in the winding position. From a comparison of 6 and 7 It can be seen that the connecting part 20 can be exchanged, so that an adaptation to different coil cores 3, in particular to coil cores 3 with central recesses 3' of different sizes, can be achieved in a simple manner.
  • a bearing element 6 provided as a counter bearing for the rotary plate 2 means that no spindle guided through the central recess 3 ′ of the coil core has to be provided, so that the insertion and in particular the removal of the coil core 3 in or out of the device 1 is significantly simplified and thus the risk of injury for the operator of the device or for other people in the vicinity of the device is reduced.
