Definitions

  • the present invention relates to a device for paraffining a thread with the aid of a paraffin body, which is mounted on a rotatable polygonal bolt, the axis of which is essentially perpendicular to the thread path between a delivery point and a winding device, and is elastically displaceable in the direction of the thread path and a stop.
  • a stop is arranged on one or both sides of the face of the thread on the end face of the paraffin body.
  • the paraffin body is supported only over a partial length by the polygonal bolt which supports and drives it, so that it is reliably excluded that the polygonal bolt protrudes beyond the end face of the paraffin body and comes into contact with the yarn. Due to the own weight of the paraffin body, a tilting moment results, by which in particular a large paraffin body lowers with its side facing the yarn.
  • the inner polygonal guide in the paraffin body becomes knocked out, so that the tilting movement is getting bigger and the entrainment of the paraffin body by the polygonal bolt is getting worse.
  • this tilting moment is usually amplified by the stop or stops, which attack the bottom half of the face of the paraffin body during the most common thread movement from bottom to top.
  • the traversing angle is very limited by the stop or stops arranged to the side of the traversing area. If the thread is exceeded, the traverse reaches the area of the trapping or stops and thus impairs the paraffinizing process.
  • the object of the invention is therefore to design a paraffinizing device of the type mentioned at the outset in such a way that a uniform rotation of the paraffin body and a uniform paraffinizing of the thread is ensured.
  • the stop is designed as a stop rail extending transversely to the thread running direction, which is arranged on the half of the end face of the paraffin body facing away from the thread unit side.
  • the measure that the stop rail extends transversely to the thread running direction is prevented with certainty that the thread can temporarily adhere to the stop during its traversing movement, so that a consequent uneven application of paraffin on the thread is excluded. Since a hold of the thread by the stop is impossible due to its orientation, a single removal in the edge area of the face side while leaving the central area of the face side of the paraffin body at the same time cannot occur; in contrast, is an even Ab ensure the paraffin body over the entire surface of its face.
  • the measure that the stop rail is arranged between the end face of the paraffin body and the thread ensures that the thread cannot become jammed between the stop and the paraffin body.
  • the moments acting on the paraffin body are essentially compensated for, so that the hollow polygon adapted to the polygonal bolt does not deflect in the paraffin body.
  • the stop rail has a widened area that extends to the edge of the paraffin body. This widening increases the contact surface of the stop rail on that side of the thread run on which the thread is not in contact with the paraffin body anyway, and causes gentle sliding on the rotating paraffin body.
  • the widening extends somewhat beyond the paraffin body on its circumference, so that the paraffin body never comes into contact with the outer edge of the stop rail can guess.
  • the flat widening is inclined towards the peripheral edge of the paraffin body.
  • the flat widening is rounded on its side facing the polygonal bolt against the paraffin body.
  • the stop rail is designed as a thread tension compensation bracket, so that a separate thread tension compensation bracket is not required.
  • the stop rail is advantageously adjustable parallel to the axis of the paraffin body. As a result, the deflection angle of the yarn on the paraffin body is changed, which also changes the contact pressure of the yarn fixed in its barrel.
  • the stop rail is expediently pivoted away from the area in front of the front side of the paraffin body, the stop rail advantageously having a thread catcher in order to remove the thread that is still running from the area in front of the end face of the paraffin body.
  • the stop rail can also be made for the stop rail to be assigned an elastic element with the aid of which the stop rail is pressed elastically against the end face of the paraffin body. Accessibility to the paraffin body can also be improved in this way by simply folding away.
  • the paraffin body is supported on a plate which can be moved without tilting along the polygonal bolt, for which purpose the plate advantageously has on its side facing away from the paraffin body a guide hub with an inner profile adapted to the shape of the polygonal bolt.
  • the plate advantageously has on its side facing away from the paraffin body a guide hub with an inner profile adapted to the shape of the polygonal bolt.
  • the subject of the invention brings about an extremely uniform removal of the paraffin body, since it is rotated permanently in a precisely fixed position. This makes it possible for the first time to process large paraffin bodies cost-effectively, which enables more economical production of the paraffin bodies and, moreover, also makes it more economical to work with paraffin waxing.
  • the paraffinizing device arranged in the thread path between an active or passive delivery point and a winding device has a rotatable guide mandrel designed as a polygonal bolt 10, which is actuated by a suitable drive device 1 (FIG. 2), e.g. a motor or a suitably driven gear, can be rotated and on which a paraffin body 2 is placed.
  • a suitable drive device 1 e.g. a motor or a suitably driven gear
  • An active delivery point is to be understood here as a delivery point which feeds the thread 3 positively to the paraffin body 2, e.g. the spinning device of an open-end spinning device.
  • a passive delivery point in the sense of this description, on the other hand, is a point from which the thread is withdrawn, e.g. the supply spool of a winding machine.
  • a thread guide 4 which can also be formed by the pair of draw-off rollers in an open-end spinning device.
  • the thread 3 is inserted into a traversing thread guide or a cross-groove roller, through which element the thread 3 is presented to a bobbin in a changing manner.
  • the thread 3 covers a triangular surface during traversing, the so-called traversing triangle 5, which is limited by the running of the thread as shown and the running 3 'of the thread shown in dashed lines.
  • the end face 20 of the paraffin body 2 is arranged in the traversing triangle 5 such that the paraffin body 2 projects beyond it laterally. This ensures that the iridescent thread 3 always rests on the end face 20 of the paraffin body 2.
  • a stop designed as a stop rail 6 is assigned to the paraffin body 2 and limits the position of the paraffin body 2 in the direction of the running thread 3.
  • the stop rail 6 extends transversely to the thread running direction and lies against the upper half of the end face 20 of the paraffin body 2.
  • the stop rail 6 is mounted in a suitable manner on both sides of the paraffin body 2 in stationary holding devices 60 and 61.
  • a compression spring 11 is supported on the machine frame 9 and holds the paraffin body 2 in contact with the stop rail 6.
  • the thread 3 lies on its way from the delivery device to the winding device on the lower half of the end face 20 of the paraffin body 2, while on the upper half of the end face 20 of the paraffin body 2 it is lifted off the paraffin body 2 by the stop rail 6 .
  • the thread 3 passes through the end face 20 of the paraffin body 2, whereby it is moved back and forth in the area of the traversing triangle 5 by the traversing device, not shown (traversing thread guide or cross-groove roller). During this movement, the thread 3 lies against the paraffin body 2 on the feed side thereof, while on the discharge side of the paraffin body 2 it is slightly lifted from the paraffin body 2 by the stop rail 6. The thickness of the selected stop rail 6 determines the length range of the thread course of the thread 3 on the end face 20 of the paraffin body 2.
  • the thread 3 is not disturbed during its traversing movement by any stops or paraffin accumulations, so that a regular traversing of the thread 3 is also ensured in the area of the paraffin body 2. This also ensures even removal of the paraffin body 2. Since the thread 3 also cannot get stuck between the stop rail 6 and the paraffin body 3, since the stop rail 6 extends essentially transversely to the course of the oscillating thread 30 between the thread and the paraffin body 2, the end face 20 of the paraffin body 2, in which this is supported on the stop rail 6, uniform wear of the paraffin body 2 is achieved.
  • the direction of the thread does not matter. While in the described embodiment the (active or passive) delivery point is below the paraffin body 2 and the winding device above it, so that the thread 3 passes through the paraffin body 2 from the bottom up, a reverse thread running direction is quite possible. In this case, the support rail 6 can still rest against the upper half of the end face 20 of the paraffin body 2, but the tip of the traversing triangle 5 formed by the thread guide 4 is located above the paraffin body 2 The advantage achieved is that the thread 3 is not jammed in the area of the stop rail 6, thereby achieving a uniform removal of the paraffin body 2. Regardless of the thread running direction, it is ensured that the paraffin body 2 rests on the stop rail 6 on that half of its end face 20 on which the thread 3 does not rest on the end face 20.
  • the thread 3 exerts pressure on the paraffin body 2 in one half of the end face 20 and the stop rail 6 in the other half of the end face 20, with a suitable choice of the thread contact pressure and of the compression spring 11 assigned to the paraffin body 2 Exerted contact pressure between paraffin body 2 and stop rail 6, the moments generated thereby largely compensate.
  • the thread guide 4 below the paraffin body 2 and the stop rail 6 are designed such that the thread essentially only on the lower half of the end face 20 of the paraffin body 2 is present.
  • the rotation of the paraffin body 2 thus always acts on the thread 3 over the entire contact length of the thread 3 on the paraffin body 2 in the same direction - and not in the opposite direction as with longer contact lengths.
  • the polygonal bolt 10 does not extend all the way to the end face 20 of the paraffin body 2, so that it cannot come into contact with the thread 3 that changes on the end face 20, which would prevent uniform waxing. Due to the weight of the paraffin body 2, it has the tendency to tilt downward on its unsupported end face 20, in particular since certain tolerances between the outer profile of the polygonal bolt 10 and the inner profile of the paraffin body 2 cannot be avoided. At a Supporting the paraffin body 2 on the lower half of its end face 20 - as is the case with the prior art - this tendency is further supported.
  • the paraffin body 2 is here always supported by the stop rail 6, regardless of the direction of the thread, on the half of its end face 20 facing away from the thread system side, so that the paraffin body cannot tilt at all. As a result, the paraffin body 2 always assumes such a position that its longitudinal axis 200 coincides with the axis 100 of the polygonal bolt 10 (FIG. 2). This ensures a uniform drive of the paraffin body 2 even over long times and leads to a uniform removal of the paraffin body 2.
  • the device described enables longer running times of the paraffin body 2, it also offers the prerequisite for larger dimensions of the paraffin body 2. This is also particularly advantageous in that it is in this way the contact length of the thread 3 on the end face 20 of the paraffin body 2, which has been somewhat shortened by the stop rail 6 extending transversely to the thread running direction, can be increased again.
  • the paraffin body 2 has a diameter of at least 50 mm.
  • the paraffin body 2 thus has, for example, 5 times the mass and a more than 5 times the service life of conventional paraffin body sizes.
  • the tilting moment is of course also significantly greater than with small paraffin bodies 2. Even if the stop rail 6 certainly generates a sufficiently large counter torque, this is nevertheless bought with the disadvantage of an increased contact force and thus increased wear.
  • the paraffin body 2 is supported on a plate 7 which can be displaced along the polygonal bolt and which has a guide hub 70 on its side facing away from the paraffin body 2 has an inner profile adapted to the outer profile of the polygonal bolt 10. This enables tilt-free displacement of the plate 7 on the polygonal bolt 10.
  • the paraffin body 2 due to the axial forces acting on it (compression spring 11 and stop rail 6) has the tendency to lie against this plate 7 with the full base area 21, the plate 7 counteracts the tilting moment of the paraffin body 2 in a safe manner, which is due to its own weight and the polygonal bolt 10 which does not extend over the full length of the paraffin body 2 is produced.
  • This effect of the plate 7 is substantially supported by the largest possible contact surface for the paraffin body 2 and achieves its optimum if the plate 7 has an annular collar 71 on its circumference, which encompasses the paraffin body 2 slightly. In this way, the paraffin body 2 can be used for a particularly long working time; Even in the case of paraffinizing devices with other stops instead of the stop rail 6 described, such a tilt-free guided plate 7 is advantageous.
  • the plate 7 it is not absolutely necessary for the plate 7 to have a guide hub 70 which projects beyond the plate base in the direction of the compression spring 11; with a corresponding thickness of the plate 7, this guide hub can also be omitted under certain circumstances if a tilt-free guiding of the plate 7 is ensured.
  • Paraffin bodies 2 are advantageous if the stop rail 6 lies as softly as possible on the paraffin body 2, in order to thereby contribute to its long service life.
  • the stop rail 6 according to FIG. 1 has a widening 62 on its upper side, with which it rests on the paraffin body 2.
  • the stop surface 63 of the stop rail 6 on the paraffin body 2 is enlarged and the pressure per unit area is correspondingly reduced at the same total system pressure.
  • the widening 62 is achieved in a particularly simple manner in that the stop rail 6 with the widening 62 is formed as a continuous sheet.
  • the sheet forming the stop rail 6 and the widening 62 projects somewhat beyond the paraffin body 2 on its peripheral edge 23 in the embodiment shown, so that the stop rail 6 has no edge in the area of the paraffin body 2 on its upper side.
  • this stop rail 62 In order to ensure that the stop rail 62 cannot cut into the rotating paraffin body 2, it not only has rounded edges, but also has a specially designed stop surface 63. According to FIG. 3, this stop surface 63 runs slightly convex towards its lower end, so that here too it is effectively prevented that an edge can cut into the end face 20 of the paraffin body 2.
  • the contact pressure of the wax body 2 against the thread 3 can be changed.
  • the plane of the traversing triangle 5 of the thread 3 is, however, defined by the thread guide 4 and the stop rail 6 which effects a thread deflection. To the contact force of the thread 3 on the paraffin To change body 2, this is moved parallel to its longitudinal axis 200, so that the thread deflection at the lower peripheral edge 24 of the paraffin body 2 is increased or decreased.
  • the paraffin body 2 is fixed in its respective axial position by adjusting the stop rail 6 parallel to the longitudinal axis 200 of the paraffin body 2.
  • the stop rail 6 has ends 64 and 65 bent on both sides parallel to the longitudinal axis 200 of the paraffin body 2 , with the help of which the stop rail 6 is mounted in the holding devices 60 and 61.
  • One end 64 has a plurality of circumferential grooves 640 arranged one behind the other, with which a locking bolt 66 elastically mounted in the holding device 60 cooperates.
  • the stop rail 6 By partially pulling out the locking pin 66, the stop rail 6 can be adjusted by one or more circumferential grooves in one direction or the other parallel to the longitudinal axis 200 of the paraffin body 2, whereupon the stop rail 6 is secured in its new position again by releasing the locking pin 66.
  • Other attachments are of course also possible.
  • the mounting of the end 65 in the holding device 61 is designed as an upwardly open groove 610.
  • the stop rail 6 in order to remove the thread 3 from the end face 20 of the paraffin body 2 at the same time without the thread withdrawal having to be interrupted, the stop rail 6 in the embodiment shown has a thread catcher 67, which reaches the area of the thread 3 sliding along the stop rail 6 and takes it to the rest position 6 'during the pivoting movement.
  • paraffinized yarn is mainly used in knitting and knitting, where the thread 3 is guided by thread guides before reaching the stitch-forming parts.
  • a paraffin film settles over time, which ensures sufficient sliding and post-waxing of the thread 3 in the case of non-waxed thread sections.
  • pivot axis 68 of the stop rail 6 it is not absolutely necessary for the pivot axis 68 of the stop rail 6 to run parallel to the longitudinal axis 200 of the paraffin body 2. Rather, it is also possible to provide a vertical pivot axis, so that the pivot plane is arranged parallel to the longitudinal axis 200 of the paraffin body 2.
  • a thread catcher 67 can also be provided here, as can the possibility of adjusting the stop rail 6 parallel to the longitudinal axis 200 of the paraffin body 2, for example by the holding devices 60 and 61 being adjustably mounted in this direction. It is also possible to have the swivel axis parallel to provide the level 22 through the end face 20 of the paraffin body 2. Such a modification of the described device is shown in FIG.
  • the stop rail 6 can undergo further modifications. For example, it is possible to design these as thread tension compensation brackets. With appropriate guidance of the thread over the stop rail 6, this can take over the task of a thread tension compensation bracket, so that a separate thread tension compensation bracket is unnecessary.
  • the size of the paraffin body 2 to be processed is in principle irrelevant to the present invention, but its use is particularly advantageous for large diameters of 50 mm or more.
