Definitions

  • the invention relates to a yarn laying device for use in the production of a wound with a yarn, preferably designed as a cheese package, with a rotatable by means of a drive about a rotation axis laying drum with a thread-guiding slot on the cylinder surface of the laying drum, wherein the axis of rotation of a shaft with two Shaft ends is formed.
  • the yarn package When producing bobbins to achieve a uniform winding of the yarn to be wound yarn over the length of the longitudinal axis, ie the stroke of the yarn package, the yarn package must be reciprocated so that a traversing movement is performed.
  • the latter is called laying.
  • This is z. B. from the US 3523652 A known to use so-called laying drums.
  • the laying drum is arranged with its axis of rotation parallel to the longitudinal axis of the yarn package in the yarn path in front of the yarn package in the yarn laying device.
  • the thread is guided in a zig-zag-shaped slot in the cylinder-like surface (cylinder surface) of the laying drum and running the axis of rotation forming shaft tangentially through the laying drum therethrough.
  • the thread is thus applied to the shaft.
  • the yarn is reciprocated over the length of the longitudinal axis of the yarn package as far as the slot extends correspondingly in the longitudinal direction of the longitudinal axis.
  • the type of winding, ie the Aufspul characterizing is thus determined by the shape of the slot.
  • the shaft is mounted on both shaft ends on the thread laying device, usually via ball bearings. So it is a two-sided storage of the laying drum used.
  • the two-sided storage of the laying drum leads to considerable installation effort in disassembly of the laying drum for their cleaning or to replace the laying drum to use a laying drum with a different Aufspul characterizing.
  • different basic components of the laying drum must be used for different strokes, as always the entire length between the mounting points of the shaft must be bridged to the thread laying device to the two-sided storage.
  • the drum must be cleaned so that, for example, a light yarn is not contaminated by the deposits (lint, softening etc.) of the previous yarn.
  • the invention has for its object to provide a yarn laying device, which avoids the disadvantages of the prior art, in particular, a rapid change of Aufspul characterizing should be possible.
  • a thread laying device for use in the production of a yarn package wound with a yarn, preferably a cross-wound bobbin, has a laying drum rotatable about a rotation axis by means of a drive with a thread-guiding slot on the cylinder surface of the laying drum.
  • the axis of rotation is formed by a shaft with two shaft ends.
  • One of the shaft ends is formed as a mounting shaft end such that the shaft is mounted with the mounting shaft end on the thread laying device.
  • the second shaft end is designed as a free shaft end. The shaft is thus mounted only on one side, so that a one-sided storage, ie a one-sided clamping of the laying drum is formed.
  • the shaft can be formed, for example directly from an electric motor in extension of the motor shaft of the electric motor or it can be provided a rotatable mounting of the shaft, so that the drive, for example as a belt drive can be trained.
  • the shaft can also be rigidly mounted, so that only the laying drum is rotatably mounted on the shaft.
  • the laying drum must therefore have no windows in the cylinder surface of the laying drum. A cleaning can be made without much effort in dismantled laying drum. If no windows are present in the cylinder surface can be dispensed with a safety housing. In the laying drum according to the invention can therefore be dispensed with a door because no rotating openings must be present.
  • the laying drum according to the invention has a hollow shaft, wherein the hollow shaft, preferably via ball bearings, is rotatably mounted on the shaft.
  • the hollow shaft is preferably pushed onto a rigid axle as a shaft and rotatably mounted thereon.
  • the shaft can be rigidly mounted on the thread laying device, so that it forms a rigid and stationary, very stable axis.
  • the drive can be directly connected e.g. engage by means of a belt drive on the hollow shaft or via a gear-type power transmission module.
  • the laying drum comprises a first drum half arranged at the end of the assembly shaft and a second drum half arranged in the region of the free shaft end, the drum halves respectively forming partial surfaces of the cylinder surface of the laying drum.
  • the thread-guiding slot is formed by a gap separating the partial surfaces.
  • the montage shaft end side arranged first half drum is fixedly connected to the hollow shaft, preferably screwed, and the second drum half is pushed onto the hollow shaft and rotatably connected to the hollow shaft with the hollow shaft.
  • a flying storage of the laying drum is realized.
  • first the second drum half can be removed and then the second drum half can be pushed down together with the hollow shaft of the shaft.
  • the second drum half is fastened on the hollow shaft via a quick-release mechanism, whereby the removal of the second drum half is further simplified, in particular for cleaning purposes.
  • the quick release mechanism can also serve to adjust the gap width of the thread guiding slot.
  • Such a quick release mechanism may comprise a screwed onto the hollow shaft with a screw thread ring, wherein the screw thread is formed on tiltably attached to the ring jaws. This results in a secure screw without the ring must be screwed tight over a larger threaded portion.
  • the gap width of the thread-guiding slot can be determined by means of the thickness and / or the number of spacer elements.
  • the partial surfaces of the cylinder surface formed by the drum halves and / or the end faces of the laying drum are advantageously designed to be free of openings.
  • the drum surface is thus closed, i. it has no opening for cleaning. This minimizes the risk of injury from the laying drum.
  • FIG. 1 shows a thread laying device according to the invention in a cross section.
  • the thread laying device has a, by means of a drive about a rotation axis 1 rotatable, laying drum 2, which forms a cylinder surface 4.
  • the axis of rotation 1 is formed by a shaft 6 with two shaft ends.
  • the shaft 6 is rigidly mounted on the thread laying device.
  • One of the shaft ends is designed as a mounting shaft end 10, such that the shaft 6 is mounted with the mounting shaft end 10 on the thread laying device and the second shaft end 11 is formed as a free shaft end, such that a one-sided mounting of the laying drum 2 is formed.
  • the laying drum 2 has a hollow shaft 14, wherein the hollow shaft 14 is rotatably mounted on the shaft 6 is pushed.
  • the hollow shaft 14 is mounted on ball bearings on the rigid shaft 6.
  • the drive is designed as an electric motor 15, which drives the rotation of the laying drum via a belt drive 16.
  • the laying drum 2 has a first drum half 21 arranged on the assembly shaft end side and a second drum half 22 arranged in the region of the free shaft end 11.
  • the drum halves 21, 22 each form part surfaces of the cylinder surface of the laying drum 2.
  • a thread guiding slot 25 is formed by a gap spacing the sub-surfaces.
  • the montagewellenenden document arranged, ie the left in the figure arranged first drum half 21 is connected by means of screws 28 fixed to the hollow shaft.
  • the second drum half 22 is on the hollow shaft fourteenth deferred and rotatably connected to the hollow shaft 14 via a flange 30 with the hollow shaft 14.
  • the second drum half 22 is secured on the hollow shaft 14 by means of a quick-lock mechanism 32.
  • the right drum half is therefore fast, e.g. removable for cleaning purposes. There may therefore be closed drum sheets, i. the cylinder surface of the laying drum 2 no longer needs to have any windows. A cover of the rotating laying drum 2, e.g. by means of a door, can therefore be omitted.
  • FIG. 2 shows two laying drums of a yarn laying device according to the invention with different Aufspul characterizinga.
  • the laying drum shown in the figure above has a stroke of 6 inches
  • the laying drum shown in the figure below has, for example, a stroke of 1.5 inches.
  • the second drum half 22 arranged in the region of the free shaft end is designed in the length of its longitudinal axis such that it can be mounted on the hollow shaft 14 at identical positions to form a desired thread-guiding slot 25. This allows a rapid changeover of the strokes of the laying drum by changing sets of the drum plates and the drum halves 21,22.
  • FIG. 3 shows a cross section of an embodiment of a yarn laying device according to the invention with a closed laying drum.
  • the mounting shaft end 10 is arranged in the figure on the left side of the laying drum 2.
  • the shaft 6 is thus mounted as a rigid shaft by means of a nut, for example a hex nut 50, on a holding element 52, for example a housing, a thread laying device, that is screwed tight.
  • the laying drum 2 has one, apart from the thread-guiding Slot 25, closed cylinder surface, ie the drum plates are closed.
  • the left half of the drum in the figure has a flange 60, on which the drum plate 61 is attached, on.
  • the flange 60 is fastened via connecting elements to the sleeve 63 serving as a hollow shaft and to a drive wheel 65.
  • the bush 63 and the drive wheel 65 are mounted on the shaft 6 via ball bearings 67, 68, in the case of the right ball bearing 68 in the figure via a sleeve 71 inserted in the shaft 6.
  • a bush 69 serves as a spacer.
  • the right half of the drum in the figure is mounted on the sleeve 63 via an anti-rotation device 70 and locked by means of a closure.
  • the closure is formed as a quick release with a snap ring 75 and screwed onto a threaded pin 76 attached to bushing 63.
  • a sensor e.g. a Hall sensor 80 which is mounted on the fixed hollow shaft 6 and monitors the axial distance of the shutter.
  • magnet holders are provided on the closure. The cable of the sensor is led away through the hollow shaft 6.
  • the two drum halves left and right form a slot 25 which moves the yarn back and forth while being wound up by the yarn package.
  • the accuracy of the thread guide (traversing movement) is influenced by the slot width. The smaller the slot, the more accurate the guide.
  • the slot width can be adjusted by spacers, which plugged onto the socket 63, the distance between the socket 63 and flange 90, in the figure to the right.
  • the slot 25 has been adjusted to the coarsest yarn to reduce set-up work.
  • the slit 25 can be set optimally in the shortest possible time to the respective yarn to be produced, ie to be wound up.
  • FIG. 4 is the thread laying device according to the invention FIG. 3 shown with open laying drum. The second drum half of the hollow shaft 6 and the sleeve 63 is pushed down, shown offset to the right.
  • FIG. 5 shows the structure of the anti-rotation device 70 for the rotationally fixed connection of the second drum half with the sleeve designated as the hollow shaft 63 in a section of a three-dimensional representation.
  • the anti-rotation device 70 is realized by cams 100 on the hollow shaft 63, which engage in grooves 102 on the second drum half.
  • FIG. 6 shows a preferred embodiment of a quick release mechanism for securing the second drum half on the hollow shaft.
  • the closure can also be realized by a quick release.
  • this thread segments 110 are used instead of the simple thread in the closure side, which can be pushed by squeezing over the thread on the left side, to the stop.
  • the thread segments 110 are provided on jaws 112 for compression. Compression of the jaws 112 allows for rapid retraction of the closure as the thread segments are thereby forced radially outward. With a minimum of effort, the closure can now be biased by turning.
  • Such a quick release is very safe against its release.
  • the thread can be self-locking.
  • An overload torque is defined by springs 114. If the tightening torque, i. the axial preload force by the quick release, is not sufficient, only the Spul briefly is impaired. The risk of injury remains low.
  • FIG. 7 shows the handling of in FIG. 6 shown quick release.
  • the quick release as in Figure 7a shown, compressed and retracted.
  • the right half drum to a stop, for example, to a positioning pin 120 for a laying edge, inserted.
  • the quick release is now released.
  • FIG. 7c shown turned on the closure until the coupling, ie the threaded jaws, snap over.
  • FIG. 8 shows a further closure variant for fixing the second drum half with a standard thread.
  • the right half of the drum is screwed by a thread 130 on the left half. This can be done with a particular freely movable rotary handle 132, which can be rotated on the right half.
  • the left half of the drum in this case has a fixedly mounted on the rotary body threaded pin 134.
  • stabilizing ribs may be provided in the interior of the laying drum.
  • a yarn laying apparatus for use in making a yarn-wound, preferably cross-wound, package trained yarn package, with a rotatable by means of a drive about a rotation axis 1 laying drum 2 with a thread-guiding slot 25 on the cylinder surface of the laying drum 2, wherein the axis of rotation 1 is formed by a shaft 6 with two shaft ends 10,11.
  • one of the shaft ends is designed as a mounting shaft end 10, such that the shaft 6 is mounted with the mounting shaft end 10 on the thread laying device and the second shaft end 11 is formed as a free shaft end, such that a one-sided mounting of the laying drum 2 is formed.
