Definitions

  • the invention relates to a thread splicing head according to the preamble of claim 1.
  • splicing Due to the better processability of threads, splicing has quickly spread as a connection between two thread ends of textile staple fiber yarns. It was also recognized very early on that the formation of the splice channel, the location at which the splice connection is made, must undergo a formation adapted to the respective yarn. This does not only refer to the supply of the compressed air required for the splicing into the respective splicing channel. The shape of the splice channel also has a significant influence on the splice result. It has also been shown that the quality of the splice connections changes over longer periods of use.
  • a thread splicing device with an exchangeable thread splicing insert which has the thread splicing channel.
  • the thread splicing channel is designed as an insert, so that a change can be made to match different yarn parameters.
  • the inserts have differently arranged openings for splice air into the splice channels. These inserts offer the possibility of interchangeability.
  • the object of the invention is therefore to keep the quality of the splice connections constant over a long period of time.
  • the invention is based on the knowledge that, for example, the condition of the surface of the splice channel is an important factor which influences the splice result.
  • the thread splicing heads of the thread splicing devices consist of metal, preferably of aluminum alloys, into which the thread splicing channel is introduced by means of a metal-cutting manufacturing process.
  • the roughness of the material that occurs during processing cannot be reproducibly controlled due to the processing methods.
  • Refining the surface of the splice channel by chemical or electrolytic deposition processes, for example by nickel plating is complex and does not lead to the desired success in the long run.
  • the protective layer is removed over time or at least a noticeable change in the surface structure. It is therefore understandable that such a modified surface of the splicing channel cannot provide reproducible splicing results in the long term.
  • the process of changing the surface of the splice channel very often runs so slowly that the deterioration of the splice connection is initially not noticeable qualitatively and quantitatively. Since the splice heads are not subjected to any optical or metallographic examination during their use, their wear only becomes apparent when there is a massive, no longer tolerable yarn defect in the splice connection. If there is an increased incidence of bad splice connections, the splice connections previously made in this splice head no longer correspond qualitatively to the splice connections that can be achieved with a new splice head.
  • Ceramic materials offer the user the possibility of the material in its green phase, ie before firing or Sintering to give any, very dimensionally stable form in reproducible quality.
  • the nature of the surface can be specified precisely on the basis of the surface of the shaping tools and is therefore reproducible.
  • the ceramic material thus advantageously offers the possibility of reproducibly giving the surface of the splice channel a predeterminable quality.
  • the splice channel can be formed, for example, from a ceramic tube that is inserted as a ceramic insert into the splice head in an adapted recess.
  • An adhesion-promoting layer can be applied between the ceramic insert in the splice head for fixing. Further aids for fixing and precisely fixing the position of the ceramic insert are conceivable, for example webs which are provided with grooves in the recess for engaging, which for example enable the exact position of the openings for supplying the splice air to one another.
  • the surface condition of the splice channel is adapted to the yarn parameters.
  • Ceramic materials have the great advantage that they are very resistant to wear. This is why thread splicing heads with a ceramic insert have a significantly longer service life than metal thread splicing heads. Furthermore, due to the resistance to wear, a constant surface condition of the splice channel is very long guarantees and thus enables the production of high-quality splice connections of constant quality over a long period of time. Since parts made of ceramic materials can be formed reproducibly and true to size, it is advantageously ensured that even inserts produced in large numbers have the same geometry and the same surface quality. This ensures that in splicing heads with ceramic inserts on a yarn-producing textile machine or on a winding machine, the thread connections produced by splicing at the individual spinning or winding positions are all of the same quality.
  • the surface of the splice channel has a defined roughness.
  • the roughness is matched to the yarn parameters, for example the fiber length or the fiber material.
  • the splice results are improved, particularly in the case of open-end spun yarns, by a high roughness.
  • a roughness of the surface of the splice channel of approximately 40 micrometers is particularly advantageous.
  • the surface of the splice channel can have a structure.
  • This can consist, for example, of longitudinal or transverse grooves or also of a helical structure of grooves and / or webs.
  • Such structures can be particularly advantageous when it comes to twisted or coarse yarns that are to be spliced or yarns that have so-called abdominal bandages at short intervals.
  • the structures cause a particularly good interlacing of the fibers.
  • the ceramic insert can advantageously consist of a thin-walled tube inserted into the splice head.
  • This tube can, for example, be glued into the thread splicing head or by other devices, for example by clamping. So that the openings for supplying the compressed air required for the splicing are always in the same place and always open into the splice channel in the same direction, it is advantageously possible to drill these openings through the splice head and the insert in one operation.
  • the ceramic insert forms the predominant part of the splicing head and only the means for fastening the splicing head in the thread splicing device are made of metal.
  • thread splice channels with a helical structure or a structure of transverse and longitudinal grooves require thick-walled inserts instead of thin-walled tubes.
  • the thread splicing head can be fastened in the thread splicing device by means of tabs guided in grooves. By loosening these tabs, the splicing head can be changed quickly.
  • Fig. 1 denotes a thread splicing device which is not shown in all its details here.
  • This thread splicing device contains a thread splicing head 2 which is screwed onto a plate 4 of the thread splicing device 1 by means of a screw 3.
  • This detachable connection enables a quick change of the thread splicing head.
  • the thread splicing head has a block-like shape and is fixed in position by a centering pin 5 on the plate 4.
  • the splicing channel 6, which is formed from a ceramic insert 7 and is fitted into the splicing head 2 in a recess 8 adapted to the ceramic insert, is incorporated in the thread splicing head 2, running obliquely from top to bottom.
  • Two openings 9 and 10 open one above the other in the thread splicing channel for supplying the compressed air required for the splicing.
  • the two openings 9 and 10 are connected to the compressed gas channel 11, which is inserted as a tube through the plate 4 into the splice head 2.
  • the insertion slot 12 of the splice channel 6 is closed by a cover 13.
  • This cover can advantageously prevent the thread ends from being blown out of the splice channel by the compressed air.
  • a splice channel which is closed in this way favors the formation of eddy currents, as is necessary for an optimal splicing of the two thread ends.
  • the cover 13 can completely cover the insertion slot 12, it consists of two Layers of different materials.
  • the layer 14 lying on the insertion slot 12 consists of an elastic, resilient material, for example soft plastic or rubber, which has been glued onto a metal carrier 15.
  • the lid 13 is actuated by a lever 16 which is connected to an actuating device of the thread splicing device, not shown here.
  • the splicing head 2 shows the thread splicing head 2 of the thread splicing device 1 in a front view, but without the cover 13 covering the insertion slot 12.
  • the splicing head 2 is fastened to the indicated mounting plate 4 with the screw 3 and centered with the centering pin 5.
  • the introduction of the compressed gas channel 11 into the back of the thread splicing head 2 is indicated by dashed lines.
  • the splice channel 6 can be seen through the insertion slot. As a result, the staggered openings 9 and 10 for supplying the compressed air required for the splicing are visible.
  • the ceramic insert 7, the ceramic tube, fitted into the recess 8 is adapted by grinding the front of the thread splicing head 2.
  • 3 and 4 show exemplary embodiments for thread splicing heads in which the surface of the splice channel has a structure.
  • 3 shows a section of a splice head 2 with a ceramic insert 7, which has a structure in the longitudinal direction of the splice channel 6 made of longitudinal grooves 17, which are separated from one another by webs 18. Due to the oblique course of the splice channel, the grooves 17 and webs 18 show a perspective course.
  • the openings 9 and 10 respectively open into one of the webs for supplying the compressed air required for the splicing. In the area of the insertion slot 12, the structuring is processed so that it does not hinder the insertion of the thread ends and the removal of the spliced thread.
  • FIG. 4 shows a section through a splice head 2 with a ceramic insert 7, in which the surface of the splice channel has a structure of transverse grooves 19.
  • the transverse grooves 19 are formed at a uniform distance from each other by webs 19 'with the same depth in the ceramic insert 7. In each of the webs 19 that have remained between the grooves 19 'open to one another, the openings 9 and 10 offset to supply the compressed air required for the splicing.
  • Thread splicing heads in which the surface of the splicing channel has a structure, are used particularly advantageously in the case of coarse yarns and in yarns which have an increased number of so-called belly bandages and which can therefore also cause difficulties in the preparation of the thread ends for the splicing process.
  • the webs and grooves support a final unraveling of the thread ends before the splicing process and an intimate swirling of one thread end with the other thread end.
  • the oblique course of the splice channels in the thread splicing heads can be replaced by another course, depending on the adaptation to the mechanics of the thread splicing device.
  • FIGS. 5 and 6 show an exemplary embodiment in which the ceramic insert forms the predominant part of the splicing head and in which only the means for fastening the splicing head in the thread splicing device are made of metal.
  • a thread splicing head 2 ' is attached, which is made of a cube-shaped ceramic piece, in which the splice channel 6 is formed.
  • the ceramic block there are also openings 9 and 10 for supplying the compressed air required for the splicing and the recess into which the compressed gas channel 11 is inserted from behind through the support plate 4 into the thread splicing head 2.
  • the thread splicing head 2 ' is fastened to the plate 4 with a fastening device 20.
  • the fastening device 20 consists of a rectangular, sheet-metal strip 21, which completely encompasses the thread splicing head 2 and, in order that the thread splicing head can be held, lies in a grooves 22 incorporated into it.
  • the sheet metal strip 21 is bent on the narrow sides of the thread splicing head 2 into tabs 23 a and 23 b, respectively, and provided with screw holes.
  • the thread splicing head 2 is fastened to the plate 4 of the thread splicing device 1 in an easily detachable manner with screws 24 a or 24 b. By means of the two screws, the thread splicing head can be quickly and easily exchanged for another thread splicing head with a thread splicing channel with a different surface, for example a structured surface.
  • the insertion slot 12 is closed with a cover 13, the structure of the cover being the same as that in the exemplary embodiment according to FIG. 1.
  • Fig. 6 shows a view of the thread splicing head 2 'according to the embodiment of Fig. 5. Again, the cover 13 is omitted.
  • the two tabs 23 a and 23 b located to the side of the thread splicing head are only one exemplary embodiment for fastening a thread splicing head in which the ceramic insert forms the predominant part of the splicing head. It is also conceivable to attach the thread splicing head 2 'to thread guide plates, not shown here, which serve as insertion aids for the thread ends to be spliced and partially cover the outlet of the splice channel in the longitudinal direction.
  • ceramic materials are very dimensionally stable under the influence of heat and do not undergo any surface changes, for example tarnishing or scaling and oxidation, they are particularly suitable for use in thermal splicers.
