Definitions

  • the present invention relates to a drive device for a waxing device of a textile machine, which has a plurality of similar waxing devices, each of which has a rotatable polygonal bolt for receiving a solid wax body, on which a thread to be waxed is supported.
  • the object of the invention is to provide a simple and safe drive device for a paraffinizing device.
  • each polygonal bolt is connected to a drive whorl with which an endless drive belt cooperating with a plurality of adjacent paraffinizing devices is in engagement.
  • a drive is extremely simple.
  • this drive has proven to be completely reliable even at the low speeds desired for the paraffin body, so that a uniform waxing of the thread is ensured even over a long period of time.
  • Drive belts in the sense of the present invention are not only understood to mean flat belts, but all elongate drive elements such as round cords, V-belts, toothed belts, etc. are to be covered herewith.
  • the drive belt is zigzagged around the drive whorls of the adjacent paraffinizing devices.
  • the drive belt jointly assigned to these waxing devices is thus alternately on the one and on the other side of the common surface, on which the polygonal bolts of these waxing devices are located, in driving connection with the drive whorls of these waxing devices.
  • the common surface can be a plane or (in the case of an inclined arrangement of the paraffining devices on round machines) also have a conical shape.
  • the drive belt is expediently connected to this shaft in terms of drive.
  • This shaft for controlling the fiber delivery is driven as a function of the fiber throughput by the open-end spinning devices, so that the paraffinizing devices are adapted to this throughput and are therefore always driven only at the speed required for this throughput.
  • the drive for the paraffinizing devices has a very long service life.
  • the drive whorl of each paraffinizing device is arranged between a holder for this paraffinizing device and the paraffinizing body. This also leads to particularly good accessibility to this drive. A further reduction in the construction effort will achieved when the polygonal bolt is formed in one piece with the drive whorl.
  • the polygonal bolt is expediently designed as a hollow body which receives the mounting and fastening.
  • the fastening has a threaded bolt which is screwed into a threaded bushing provided in the holder.
  • the cavity of the polygonal bolt can be closed at its end facing away from the bearing by a cap which projects beyond the outer circumference of the polygonal bolt and is designed as a stop for an elastically loaded paraffin support plate mounted on the polygonal bolt.
  • the flap advantageously has corners, the polygonal bolt protrudes on its chamfered edges, while the side surfaces of the polygonal bolt and the cap are flush, the paraffin support plate having guide surfaces which are closely matched to the profile of the polygonal bolt. In this way it is achieved that the paraffin body can be pushed over the insert serving as a stop for the paraffin support plate onto the polygonal bolt without the play between the polygonal bolt and the paraffin body having to be increased.
  • a support element for the returning run of the drive belt is preferably provided.
  • this support element is advantageously arranged just below this thread tension compensation element, so that the drive belt is protected by this cover.
  • the support element serves as a carrier for a stop limiting the advancing movement of the paraffin body.
  • a carrier designed as a supporting element is arranged on both sides of the paraffin body, the stop extending from one of these carriers to the other carrier.
  • the support element which is arranged in front of the paraffin body with respect to the rotational movement acting on the stop, is expediently designed as a pivot bearing for the stop, while the support element arranged after the paraffin body has a longitudinal slot on its side facing away from the waxing device for receiving the end of the stop having.
  • an open channel can be provided for this run on its side facing the paraffinizing device, which in an advantageous embodiment of the subject matter of the invention is formed by the holder and a cover strip, which is an integral part of the thread tension compensation element.
  • the invention preferably provides for the rotational speed of the paraffin body to be adapted to the fiber mass fed to the open-end spinning device .... This happens, as already mentioned above, preferably in that the drive of the paraffin body is removed directly from the shaft carrying the delivery rollers, but another is - for example electrical - speed coupling also possible in principle.
  • the invention provides a simple device that is compact, requires little energy to drive the paraffin body and that works reliably without maintenance. Despite the low mechanical engineering effort, the device is durable and user-friendly.
  • the invention can be used in various textile machines on which the thread can be waxed.
  • the textile machines can have an elongated or a round shape.
  • it does not matter whether it is yarn-producing spinning machines, yarn-treating winding machines or yarn-processing machines (knitting or warp knitting machines).
  • an open-end spinning machine (FIG. 1) was selected as an example, which has a large number of spinning positions 1 and, accordingly, paraffinizing devices 2.
  • the spinning machine shown has seven spinning positions 1; in practice, however, these are considerably more.
  • the spinning machine itself is only shown schematically, all the elements of which are not absolutely necessary for the understanding of the invention Were omitted for the sake of clarity.
  • the open-end spinning machine has an end frame 11 and 12 at each end.
  • the spinning machine has one spinning device covered by a cover 10 for each spinning station 1.
  • the fiber material 13, which is presented to it in a spinning can 14, is fed to the spinning device with the aid of a delivery device which is driven by a shaft 19 which extends over the entire length of the machine.
  • the thread 15 spun in the spinning device is drawn off with the aid of take-off rollers 17 and 18 and wound onto a bobbin 16, the thread 15 being presented to the bobbin 16 in an alternating manner in the usual and therefore not shown.
  • a waxing device 2 is arranged in the thread path between the take-off rollers 17 and 18 and the bobbin 16 (or a yarn processing point in the case of yarn processing machines).
  • Each waxing device 2 has a polygonal bolt 4 (FIG. 2), on which a waxing body 21 for waxing the thread 15 is attached.
  • the polygonal bolt 4 is connected in terms of drive to a drive whorl 20.
  • the drive whorls 20 of the paraffinizing devices 2 of a large number of adjacent spinning positions 1 are driven by a common drive belt 3.
  • the drive belt 3 can always rest on one and the same side on the drive whorls 20 (FIG. 2) of the paraffinizing devices 2, the drive belt 3 being tensioned by conventional tensioning rollers, not shown, and held in contact with the drive whorls 20.
  • the paraffin bodies 21 are driven uniformly in this way. Even if the moment exerted by the thread 15 on the paraffin body 21 changes briefly as a result of changes in the thread tension, a change in the rotational speed which is not so great that could impair the perfect waxing of the thread 15 is nevertheless achieved. Rather has shown that the waxing of the thread 15 and the processing of the wax body 21 takes place very uniformly.
  • FIG. 1 A particularly advantageous embodiment of the device is described below with reference to FIG. 1, in which the drive belt 3 wraps around the drive whorls 20 (FIG. 2) in a zigzag fashion.
  • the axes of the paraffinizing devices 2 are on a common surface E, while the driving strand 30 alternately on one and on the other side of this surface E with the drive whorls 20 (FIG. 2) of the paraffinising devices 2 in drive connection is.
  • every second paraffin body 21 is driven in a clockwise direction, while the paraffin bodies 21 located in between are driven in a counterclockwise direction.
  • this is irrelevant for the waxing of the thread 15, which is waxed equally well regardless of the direction of rotation of the wax body 21.
  • this surface E is a plane (in the case of elongated machines and in the case of round machines in which the axes of the paraffin waxing devices 2 extend exactly radially outward) or a conical surface (in the case of round machines in which the axes of the paraffin devices 2 are inclined).
  • the zigzag guide of the drive belt 3 keeps it taut and wraps around the drive whorls 20 over a larger area than with conventional tangential drives, so that a good entrainment of the drive whorls 20 is nevertheless achieved when tensioning rollers are omitted.
  • the drive belt 3 can also be driven in any desired manner.
  • the drive belt 3 receives its drive from the shaft 19, with which the fiber material 13 is fed to the spinning device.
  • a drive roller 32 is arranged on the shaft 19 in the vicinity of the end frame 11.
  • a further deflection roller 34 with which the drive belt 3 is fed to the deflection roller 33 at an optimal angle.
  • the drive belt 3 is in contact with the drive whorls 20 of the paraffinizing devices 2 alternately from above and from below.
  • the drive belt 3 is deflected by a further deflection roller 35 in the vicinity of the end frame 12.
  • the returning run 31 of the drive belt 3 is then returned above the paraffinizing devices 2 to a deflection roller 36 in the vicinity of the end frame 11, from where the drive belt 3 reaches the drive roller 32 again.
  • the drive of the drive belt 3 from the shaft 19 of the feed device of the open-end spinning machine causes the paraffin body 21 to be driven at a speed adapted to the fiber throughput. If a lot of sliver is fed to the open-end spinning devices, so that the fiber throughput is high, then the stretching speed of the paraffin bodies 21 increases accordingly. If less sliver is fed to the spinning devices, the speed of rotation of the paraffin bodies 21 is also reduced accordingly, so that the paraffin bodies 21 can only be driven at the required speed and not faster. This leads to a longer service life of the drive of the paraffin devices 2.
  • a particularly advantageous embodiment of the drive device and the correspondingly configured paraffinizing device 2 will be described below with reference to FIGS. 2 and 3.
  • This is carried by a bracket 5 designed as a holding plate.
  • a threaded bush 40 is pressed into the holding plate 5 or firmly connected in another way, into which a threaded bolt 41 is screwed.
  • On the threaded bolt 41 are two roller bearings 42 and 43, on which the polygonal bolt 4 is rotatably mounted.
  • the polygonal bolt 4 is designed as a hollow body, which on the one hand has the advantage that the threaded bolt 41 is accessible from the front of the polygonal bolt 4, and on the other hand reduces the weight of the waxing device 2 and thus contributes to an increase in its service life.
  • the polygonal bolt 4 has a polygonal profile 400, on which a paraffin support plate 44 with a guide section 440, which has a guide surface 441 adapted to the polygonal profile 400, is slidably mounted.
  • a paraffin support plate 44 with a guide section 440 which has a guide surface 441 adapted to the polygonal profile 400, is slidably mounted.
  • the paraffin support point 44 merges into a radial support surface 442 which is delimited by an annular collar 443 which axially projects beyond this support surface 442 on its side facing away from the drive whorl 20.
  • the drive whorl 20 is connected to the polygonal bolt 4 only with a radial connecting surface 200, so that an annular recess 45 for receiving a compression spring 46 is formed between the drive whorl 20 and the polygonal bolt 4.
  • this compression spring 46 which is supported on the radial connecting surface 200 on the one hand and on the radial support surface 442 on the other hand, the paraffin support plate 44 is acted upon in the direction of the free end of the polygonal bolt 4 and in this way ensures that the paraffin body 21 is always in predefined dimensions protrudes into the thread running plane so that it bears against the thread 15 in the desired manner.
  • the paraffin body 21 is held in this position against the action of the compression spring 46 by a stop 6, which will be described in more detail later.
  • the polygonal bolt 4 is designed as a hollow body.
  • a cylindrical extension 470 of a cap 47 projects into the open end of the polygonal bolt 4 facing away from the drive whorl 20.
  • This cylindrical extension 470 serves to fasten the cap 47 in the polygonal bolt 4. This can be done by means of cooperating catches or by a correspondingly tight fit between these parts.
  • the cap 47 also has a stop surface 471 with which it rests on the end face of the polygonal bolt 4. As shown in FIG. 4, the side surfaces 472 of the cap are flush with the side surfaces of the polygonal bolt 4. In contrast to the edges of the abutment surface 471 of the cap 47, the edges of the polygonal bolt 4 are provided with chamfers 401. In this way, the corners 473 transmit these chamfers 401.
  • the guide surface 441 of the paraffin support plate 44 is adapted to the polygonal profile 400 of the polygonal bolt 4, and thus also has surfaces corresponding to the chamfers 401 of the polygonal bolt 4.
  • the corners 473 of the cap 47 thus form a stop for the paraffin support plate 44 and hold it securely on the polygonal bolt 4.
  • the cap 47 Since the side surfaces 472 of the cap 47 are flush with the side surfaces of the polygonal bolt 4, the cap 47 in no way hinders the pushing of a paraffin body 21 onto the polygonal bolt 4 and likewise does not impair its displacement on the polygonal bolt 4.
  • the cap 47 has a central bore 474 which, without the cap 47 having to be removed from the polygonal bolt 4, enables access to the threaded bolt 41. This facilitates rapid removal of the paraffin device 2 should this become necessary.
  • the drive whorl 20 of the paraffinizing device 2 is located between the holder 5 for the paraffinizing device 2 and the paraffin body 21.
  • this is not a requirement.
  • the drive belt 3 is returned along the driven paraffinizing devices 2 to the drive point (shaft 19, see FIG. 1).
  • the drive belt 3 is kept so tensioned that the two strands 30 and 32 do not touch each other 2 and 3, support elements 60 and 61 are provided for the returning run 31 of the drive belt 3, which is out of engagement with the waxing devices 2, in principle, in long machines in which a large number of paraffinizing devices 2 are driven with this drive belt 3 it is sufficient if only one support element 60 or 61 is provided per paraffinizing device 2, it not even being necessary for each Paraffinizing device 2 has such a support element 60 or 61.
  • the support element 60 is designed as a carrier of the stop 6 limiting the advancing movement of the paraffin body 21.
  • a single supporting element 60 of this kind is sufficient for each paraffinizing device 2.
  • there is one on each side of the paraffin body 21 according to FIG such provided as a support for the stop 6 support element 60 and 61 is provided.
  • the stop 6 extends from one support element 60 to the other support element 61 of such a support element pair.
  • the stop 6 can be rigidly connected to both support elements 60 and 61.
  • a clamping screw 62 is only provided for the support element 60.
  • the support element 61 has on its upper side - i.e. on its side facing away from the polygonal bolt 4 of the paraffinizing device 2 - a longitudinal slot 610 for receiving the other end of the stop 6.
  • the rail-shaped stop 6 can thus be pivoted into and out of the operating position in the support element 61 forming a pivot bearing, so that the exchange of the paraffin body 21 and the subsequent securing thereof on the polygonal bolt 4 can be accomplished in the simplest and fastest manner can.
  • the thread 15 to be waxed is moved from bottom to top (see arrow B in FIG. 3).
  • the stop 6 is located on the thread outlet side of the paraffin body 21.
  • the paraffin body 21 rotates in the direction of the arrow D counterclockwise.

  • the support element 60-arranged which is designed as a pivot bearing for the stop 6.
  • the support element 61 having the longitudinal slot 610 is arranged accordingly after the paraffinizing device 2.
  • the rotating paraffin body 21 causes the stop 6 to be pressed into the longitudinal slot 610 and thus secures the stop 6 in its operating position.
  • the reason for this is that two opposing moments M and m act on the stop 6, of which, however, the moment M having the larger moment arm (based on the support element 60) outweighs the moment m having the smaller moment arm.
  • the support elements 60 designed as pivot bearings and the support elements 61 having the longitudinal slot 610 of each second paraffin device 2 in the arrangement shown and the paraffin devices 2 located in between are also shown reversed arrangement provided.
