Definitions

  • Devices for applying a wire coil to a fine wire strand by throwing or wrapping one wire around a thin wire strand being conducted through an elongated hollow bore or axis of the device are in themselves known. Some of these devices operate according to the socalled flyer principle, i.e. wherein one element, which consists of a revolving arm with guide holes or grooves for the coiling wire or a revolving disk with one or more bores in the vicinity of its edge, is rotated at a speed adjusted to the chosen feed rate of the wrapped wire and the desired pitch of the coiling wire.
  • This rotating element lifts the coiling wire from a freely turnable but braked supply reel borne coaxially to the advancing wire strand or cable and winds this coiling wire simultaneously at the winding point, i.e., at the point at which the coiling wire runs onto the fine wire strand or cable as a core receiving the coiled 'wire wrapped therearound.
  • the supply reel (or reels) for the coiling wire is borne in a rotor by means of a coil cradle, from which the coiling 'wire is guided axially to the winding point.
  • the fine wire strand or core cable runs from a different supply reel arranged outside the rotor axially through a suitable bore on the axis and is then directly conducted to the circumference of the rotor, along an inner surface thereof to the opposite end of the rotor and finally to the winding point where it is wrapped about the coiling wire and is drawn off in such a manner that the fine wire strand is straight and the coiling wire takes on the desired-helical or coiled form.
  • the first described device makes necessary a separate bearing of the flyer and supply reel, in which generally the flyer is part of a central revolving spindle on which the supply reel, in turn, is borne freely turnable but in a braked manner.
  • the wire tensioning takes place through the braking of the supply reel in this instance while the braking force itself depends on a number of influencing factors changing in part during the operation of the spindle or at any rate is subject to possible variations. Because of the resulting changes in wire tension it was not possible to actually achieve equal or uniform working conditions, especially in the case of several similar working points, or else these equal working conditions were only infrequently achieved with great difficulty.
  • the device of the invention for applying a wire coil to a fine wire strand thus includes a rotatable hollow shaft adapted to receive the fine wire strand being wound in combination with means for drawing this strand axially through said shaft, a rotationally symmetrical pot receptacle joined securely to the shaft for rotation therewith and being open toward the wire exit end of the shaft which projects axially outwardly from the pot receptacle, a supply reel for the coiling wire seated in a fixed position on the shaft concentrically within the pot receptacle, and wire guiding and braking means positioned along the axis of the shaft between the supply reel and the axially exposed exit end of said shaft, these means including at least two annular run-over rings together with at least one disk brake means which interact with the opposing inner peripheral wall surface of the pot receptacle to apply
  • the hollow shaft is preferably conically narrowed at its exit end in order to better accommodate the path of the coiling wire as it approaches this end of the shaft, i.e., so that the coiling wire can be brought onto the core or central strand being wound at an acute angle away from or opposite to the direction of wire travel.
  • An axial insert with a narrow bore at the tip or exit end of the hollow shaft is also of advantage in controlling the draw or pull on the fine wire strand.
  • the pot receptacle surrounding the hollow'shaft is cylindrical from its bottorn up to a height or axial length which corresponds approximately to the length of the supply reel for the coiling wire, and from this length onwardly toward its open end widens conically outwardly, the total height or length of the receptacle being about 1.5 to 2.2 times the length of the supply reel.
  • the construction of the invention also preferably provides clamping means including, for example, an annular nut which can be tightened by screwing it on a threaded portion at the exit end of the hollow shaft and which simultaneously fixes the guiding and braking means in place and, in so doing, also fixes the supply reel inside the pot receptacle surrounding the hollow shaft, for example, such that the supply reel is pressed with its rear flange against the inner base or covered end of the pot.
  • clamping means including, for example, an annular nut which can be tightened by screwing it on a threaded portion at the exit end of the hollow shaft and which simultaneously fixes the guiding and braking means in place and, in so doing, also fixes the supply reel inside the pot receptacle surrounding the hollow shaft, for example, such that the supply reel is pressed with its rear flange against the inner base or covered end of the pot.
  • the braking means are preferably in the shape of disks which can consist of a wearproof and resilient plastic material, for example a suitable elastomeric molded polymer such as a plasticized polyvinyl chloride (PVC), tetrafluorethylene or similar tough, flexible materials.
  • PVC plasticized polyvinyl chloride
  • These braking disks can also be coinposed of annularly positioned bristles arranged next to one another in several layers and projecting radially outward from the periphery of a flat retaining disk.
  • the bristles can be natural fiber bristles such as animal bristles, synthetic fibrous bristles such as polyarnide bristles, metal bristles as formed by short steel wires or the like, and similar stiff but resiliently positioned bristles.
  • the braking force is also variable by other means, for example such that with equal brake disk measurement, one can vary the difference in diameter between the brake disk or disks and the diameter of the disk or disks guiding or tensioning the coiling wire being drawn thereover.
  • FIG. 1 is a vertical sectional view, in partly schematic form, through the longitudinal axis of the wrapping or coiling device of the invention
  • FIG. 3 is a schematic flow sheet generally illustrating the wrapping or coiling units of the invention with means to draw the wound product therefrom.
  • the hollow tubular shaft 1 is illustrated in a vertical position, the shaft being joined or securely connected to a pot 2 consisting of the lower cylindrical part 3 and the upper conical part 4 opening outwardly.
  • the hollow shaft 1 and the pot receptacle 2 are represented as being made of one piece, which is generally recommended when operating at rotational speeds of about 10,000 to 15,000 rpm or even higher speeds.
  • the pot can also be made separately of materials especially adapted to resist the high strain imposed thereon and can then be connected with the hollow shaft in any suitable manner at its base or lower closed end 5 such that a faultless rotational balancing becomes possible.
  • the channel or bore la of the hollow shafts terminates, in the embodiment shown, in an inserted nozzle member 6 converging in the form of a funnel or cone 6a down to the narrower diameter channel or bore 6b.
  • the terminal or nozzle end of the hollow shaft is contained with the outer element 7 which is firmly connected, e.g., in threaded attachment, and axially aligned with the remainder of the hollow shaft 1.
  • This nozzle 7 also contains at its coni-
  • the hollow shaft or spindle 1 is supported rotatably in two ball bearings 9 and 10 inserted at a distance from each other with the help of spacing sleeves 1 1 and 12 in a bearing housing 21 securely connected with a horizontal base frame 13, this bearing assembly being closed off underneath with a cover or cap 14 in which there is a suitable positioned sealing and packing ring 15 and 16.
  • Another packing ring 17 is positioned adjacent the upper bearing 9.
  • the bearings 9 and 10 can be lubricated with a suitable oil or grease introduced through the closable lube hole 22 in the housing 21.
  • An upper sealing-ring is not essential in this vertical position of the shaft 1 and housing 21.
  • a pinion or toothed collar 18 is secured with the aid of a spline or key 18a or the like, this pinion or collar 18 serving as a driven means in which there engages a toothed belt or other positive drive means (not represented).
  • the pinion 18 is fastened tightly with the aid of a ring nut 19 and a retaining ring or washer 20.
  • the brake discs are shown schematically in the sense that there are represented on one side of the vertical section the brake rings 28 and 30 consisting of a wearproof plastic, e.g., PVC disks, and on the other side the brake rings 28 and 30' with bristles extending radially outwardly from their edges to bend slightly in contact with the inner wall surface 35 of the conical part 4 of pot 2.
  • the disks with bristles are especially well suited for very high turning rates, i.e., very high draw-off speeds of the wound wire 36, while the flat-shaped solid disks have special advantages for braking at lower draw-off speeds of the wound wire cable 36.
  • the brake disks 30' provided with bristles 30a preferably contain a large number of these bristles densely packed into two or more rows and tightly held between two halves 30b and 30'c of the plate portion of the disk.
  • the bristles 30a can be bonded or set in an annular holding member 30'd to prevent them from being too easily pulled out as they frictionally engage and apply tension to the coiling wire 37 in running contact therewith.
  • the fine wire strand 38 wound about at the exit from hollow nipple 8 with the wire 37 is thereupon conducted as the wound wire 36 through a pressing die or compression bore 41, wherein the helically wound wire receives its final carefully shaped form adapted exactly to the circumference of the fine wire strand 38 and then drawn and wound for collection on the collecting spool means 42, if desired with guide or nip rolls 43 and/or other drawing or tensioning means.
  • the means for feeding the initial fine wire strand or core wire from below is quite conventional as are the drawing means illustrated in FIG. 3.
  • the present invention is therefore adapted to be used in combination with any such feed and draw means, particularly since a separate feed and/or draw located outside of the device itself is not required for the cooling or wrapping wires.
  • the assembly and operation of the device according to the invention is extremely simplified, much lower in cost and designed to provide excellent uniformity in sequential and/or parallel winding and coiling operations as well as in asingle winding operation.
  • Apparatus for applying a wire coil to a fine wire strand which comprises:
  • a rotatable hollow shaft adapted to receive the fine wire strand being wound in combination with means for drawing said strand axially through said shaft; rotationally symmetrical pot receptacle joined securely to said shaft for rotation therewith and being open toward the wire exit end of said shaft which projects axially outwardly from said pot receptacle;
  • clamping means include a tightening nut-threaded onto the exit end of said hollow shaft to engage and clamp
  • a brake disk cooperating with the wall of the pot receptacle is composed of a resilient, wearproof plastic material.
