Definitions

  • the invention relates to a wire drawing device, in particular for a wire enamelling machine, in which wire to be coated, continuously withdrawn from an unwinding device, is wound several times around at least two spaced, axially parallel roller blocks, passes through the processing stations of the wire enamelling machine several times during circulation around these roller blocks and is finally removed from the roller block arrangement becomes.
  • a wire coating machine of the type mentioned above is known for example from DE-PS 31 18 830.
  • a lacquer application device for applying lacquer to the wire, an oven for baking the lacquer onto the wire and a drying or curing device for drying and subsequent hardening of the lacquer are provided one behind the other.
  • the wire to be coated with varnish is drawn off from wire spools by means of a wire drawing device, wound several times around two spaced-apart, opposite deflecting rollers, so that the wire passes through each of the processing stations several times, so that the required varnish layer thickness is gradually built up, the one with a Finished enameled wire provided with the required thickness is finally removed from the deflecting rollers and wound up on an enameled wire winding device.
  • either a single wire or alternatively also a plurality of wires can be coated in parallel with lacquer, in the latter case two or more wires being guided parallel to one another and wound around the deflection rollers.
  • the wire end or the wire ends must be passed through the processing stations by hand at the beginning of the coating process and wound around the roller blocks. This is a cumbersome and time-consuming procedure, especially when you take into account that the distance between the roller blocks is usually between about 10 and 15 m and the insertion of the wire can not be carried out by a single person, especially if the Wire enamelling machine has a vertically oriented construction, d. H. the roller blocks are arranged vertically one above the other. Furthermore, pulling in the wires by hand is subject to numerous sources of error. There is in particular the risk that the groove of the roller block assigned to the respective winding is inadvertently selected. Furthermore, the wire can also twist undesirably during insertion. Additional problems result from the fact that the wire guide is not visible in certain processing stations such as, for example, in the furnace and in the wire cooling device, which additionally complicates the proper threading of the wire.
  • the invention is therefore based on the object of simplifying the drawing of the wires into the wire enamelling machine and of eliminating possible sources of error as completely as possible.
  • an automatically operating wire pulling device having a laying bar running around the roller blocks and parallel to the axis of the roller blocks, on the laying bar an axially displaceable sled is arranged, the sled is a device for fastening has at least one wire end, the carriage carries a guide element which extends transversely to its plane of movement, and wherein a stationary switch arrangement is arranged in the path of movement of the guide element, which axially displaces the guide element during each revolution around the roller block arrangement by a distance which corresponds to the axial displacement corresponds to two adjacent windings of the wire on the roller block arrangement.
  • the wire end is fastened to the slide, the slide being in the initial situation, viewed in the axial direction, at one end of its displacement path, the position of which corresponds to the axial position of the first guide groove to be covered with the wire, the roller blocks .
  • the laying beam is put into circulation, whereby, pulling the wire behind it, it places it in the first groove of the roller blocks.
  • the switch arrangement so that the guide element of the carriage comes into engagement with this switch arrangement.
  • the slide is displaced in the axial direction relative to the laying beam by an amount corresponding to the distance between two guide grooves of the roller blocks over the guide surface of the switch arrangement which runs obliquely to the wire direction.
  • the wire is therefore inserted into the second grooves of the roller blocks adjacent to the first grooves sets.
  • the process described above is repeated until the wire is completely and properly wound on the roller blocks.
  • the circulation of the laying beam is stopped, the wire end is detached from the slide and fed to the enamelled wire winding device.
  • the above statements refer to the pulling in of a single wire. If several wires are to be drawn in at the same time as a harp, the corresponding procedure is followed.
  • the ends of the plurality of wires are attached to the carriage at a predetermined distance and the switch arrangement is designed in this case so that the carriage is displaced by a multiple of the distance between adjacent guide grooves corresponding to the number of wires to be drawn in at each pass.
  • the automatic wire pulling device thus ensures rapid, simple, reliable and error-free pulling in of both a single wire and a plurality of wires simultaneously.
  • two endless carriers are provided for moving the laying bar, around which the roller blocks are arranged, arranged on both sides of the winding area of the wire or wires, on which the ends of the laying bar are carried.
  • These carriers can be formed, for example, by chains, ropes or the like, but the carriers preferably consist of heat-resistant perforated tape of suitable material.
  • the carriers After the carriers rotate around the roller blocks, they can be driven by means of the same drive as the roller blocks, so that a separate drive is unnecessary.
  • the carriers rotate on rollers which are coaxial with the roller blocks and can be coupled only with these, so that the roller block or the rollers carrying the carriers can be driven separately from one another.
  • the band-shaped carriers have perforations which cooperate with the projections formed on the roller blocks, which results in a particularly secure, form-fitting engagement of the band carriers with their transport means and thus a particularly safe and reliable forward movement of the wire to be drawn in Laying bar results.
  • the laying bar can expediently be releasably attached to the carrier, so that after the wire has been drawn in, the laying bar can be removed from the carrier tapes and the carrier tapes can run together with the wire during operation of the wire coating machine without having to be uncoupled from the roller blocks.
  • the carriage may be expedient to releasably attach the carriage to the laying beam so that it can be easily replaced, for example, if a plurality of wires are to be drawn in simultaneously instead of a single wire and therefore the carriage must have a plurality of fastening devices for the wire ends.
  • the stationary switch arrangement is also arranged interchangeably, since the switch arrangement must produce a different degree of displacement depending on the number of wires to be drawn in simultaneously.
  • the switch arrangement has a number of guide surfaces which come into engagement with the guide element of the slide and which correspond to the number of windings of the wire on the roller block arrangement and which are arranged next to one another in the axial direction and are inclined with respect to the central plane connecting the roller blocks. Seen in the direction of movement of the guide element, the guide surfaces define a funnel-shaped entrance area for the guide element and an exit area, the width of which corresponds to the width of the guide element.
  • a limit switch can be arranged in the path of movement of the guide element or of the slide, which switches off the circulation of the laying beam after the winding process has ended, so that improper winding due to additional, undesired windings is avoided with certainty.
  • a functional wire pull-in device of the type according to the invention can also be designed such that the switch arrangement on the slide of the laying beam and the guide element are arranged in a stationary manner.
  • the arrangement with a stationary switch and movable guide element is generally preferred.
  • the wire coating machine shown only partially and very schematically in FIGS. 1 and 2 comprises two opposing, coaxial roller blocks 10, 12, around which the wire 14 to be coated is guided in several layers or windings 16.
  • the roller blocks 10, 12 have guide grooves 18 for the wire 14 which are evenly spaced in the axial direction.
  • the distance between the individual windings 16 corresponds to the distance between the individual guide grooves 18 of the roller blocks 10, 12.
  • the roller block 10 is biased in the direction of the connecting plane of the two roller blocks 10, 12 away from the roller block 12 so that the required tension is exerted on the wire 14 wound on the roller blocks in order to keep the wire 14 tensioned.
  • the roller block 12 can be driven in the arrow direction A by a drive motor 20.
  • the wire 14 to be coated is drawn off from a wire spool (not shown) by means of a wire drawing device (also not shown) and fed via a deflection roller 22 to the outermost guide groove 18a of the roller block 10.
  • the enamelled wire finished in the processing stations of the wire enamelling machine is, as shown at B, discharged via suitable deflection rollers, not shown in more detail, and wound onto an enamelled wire winding device, also not shown.
  • the wire 14 wound in a plurality of windings 16 onto the roller blocks 10, 12 passes through the various processing stations of the wire coating machine, namely in particular the coating application device 24, the oven 26 and the drying and curing device 28, in several passes depending on the number of windings, until the required coating thickness is reached.
  • a plurality of wires 14 are to be machined simultaneously in a manner not shown in more detail, a plurality of wires 18 which are parallel to one another are accordingly fed simultaneously via a plurality of deflecting rollers 22 which are staggered next to one another.
  • the number of passes of the multiple wires through the individual processing stations corresponds to the ratio of the number of grooves to the number of wires.
  • roller block 10 instead of the roller block 10 with a large diameter, two separate roller blocks 10a, one above the other, 10b each of a smaller diameter are shown, but the two arrangements are to be regarded as completely equivalent.
  • the wire retraction device designated as a whole in FIG. 3 by reference number 30, comprises two carrier tapes 32, 34 made of suitable heat-resistant material, which are circumferentially guided over the axial end regions of the roller blocks 10a, 10b, 12 and have perforations 36 which have corresponding pin-shaped projections 38 , which protrude radially outward on the circumference of the two ends of the roller block 12, cooperate in terms of drive, so that when the roller block 10 is driven by means of the drive motor 20, the carrier tapes 32, 34 are reliably driven together.
  • a laying bar 40 which runs transversely to the running direction of the carrying tapes, i.e. parallel to the axes of rotation of the roller blocks, is detachably fastened and carries a carriage 42 movable in the longitudinal direction of the laying bar 40, i.e. parallel to the axes of rotation of the roller blocks.
  • the carriage 42 has a device (not shown in more detail) for fastening the end of the wire 14, with which the end of the wire is clamped, for example, on the carriage.
  • this carriage has a plurality of fastening devices which are spaced apart from one another in the direction of displacement of the carriage 42 by the predetermined distance between the individual wire windings.
  • a displacement of the carriage 42 within the laying beam 40 counteracts at least such a frictional force that an unintentional or unintentional displacement of the carriage 42 relative to the laying beam 40 is avoided.
  • a downwardly projecting guide pin 44 is fastened, which, when the laying beam 40 rotates, also a switch arrangement 46 comes into engagement.
  • the switch arrangement 46 is arranged stationary with respect to the wire pulling-in device 30 and has a number of guide grooves 48 corresponding to the number of guide grooves 18 of each roller block 10a, 10b, 12, which extend approximately in the wire direction, but run somewhat obliquely with respect to this, so that the guide pin 44 entering one of the guide grooves 48 experiences an axial displacement in the direction of the axis of the roller blocks as it passes through each guide groove 48.
  • the axial dimension of this offset corresponds to the distance between the individual guide grooves 18 on the roller blocks 10a, 10b, 12.
  • Each guide groove 48 has an inlet area 50 which widens in a funnel shape and an outlet area 52 which is narrower than the input area 50, the width of the guide grooves 48 in the exit area 52 is only slightly larger than the diameter of the guide pin 44. Seen in the axial direction, the exit areas 52 of the guide grooves 48 are located exactly at the level of the guide grooves 18 of the roller block 10 or 10b assigned to them, while the entry areas 50 are in the axial direction seen exactly at the level of the guide grooves 18 of the roller block 12 assigned to them.
  • the configuration described above ensures that the guide pin 44 that runs out of the switch arrangement 46 with the wire end attached to it is exactly at the level of the respectively assigned guide groove 18 and that even if the position of the slide 42 relative to the laying beam 40 during a Rotation should be adjusted slightly, due to the funnel-shaped widening of the input areas 50 of the guide pin 44 is reliably inserted into the corresponding, next guide groove 48.
  • the carriage 42 To pull in a wire, the carriage 42 is first brought into its starting position, which is defined by a stop (not shown), and the end of the wire is fastened to the fastening device of the carriage 42. Subsequently, the roller block 12 and thus the support straps 32, 34 coupled to the drive motor 20 are rotated via the drive motor 20, as a result of which the laying beam 40 is rotated. As a result, the wire 14 is gradually inserted into adjacent guide grooves 18 of the roller blocks, the guide pin 44 coming into engagement with the switch arrangement 46 each time the laying beam 40 rotates, and is displaced by the distance between two adjacent guide grooves until the wire is completely open the roller blocks are wound up or wound up. As can be seen from FIGS.
  • the last position of the drawn-in wire is guided onto the lateral flange 54 of the roller block 12, with a pressure roller 56 which is movably mounted and preloaded on this flange 54, the end region of the tensioned wire between itself and the flange 54 pinched in order to prevent the wire end from being pulled back into the wire enamelling machine due to the tension acting on the wire when the wire end is subsequently released from the carriage 42.
  • the individual processing stations of the wire coating machine must be designed in such a way that passage of the laying beam 40 together with the slide 42 is made possible, but this generally does not pose any difficulties.
  • the paint application devices 24 constructed in the form of a nozzle or made of impregnated felt parts can be designed to be divisible in the wire plane, and a part of these paint application devices can be lifted off or removed for the purpose of pulling in the wire.
  • the outer roller parts 60 to 70 carrying the carrier tapes 32, 34 can be rotated independently of the associated roller blocks 10a, 10b, 12 and the roller parts 60, 62 of the drivable roller block 12 can be coupled to the roller block 12 for the purpose of driving the laying beam 40.
  • the laying beam 40 is left in a non-disturbing position outside the processing stations of the wire coating machine and the roller parts 60, 62 are uncoupled from the roller block 12.
  • a carriage 42 provided with a corresponding number of fastening devices and a correspondingly modified one Switch arrangement 46 is used, in which the axial displacement of the slide per revolution is a multiple of the wire spacing or the spacing of adjacent guide grooves 18 corresponding to the number of wires.
