Definitions
- the invention relates to a twist stop device for guiding a thread according to the preamble of claim 1.
- a false twist is produced on a multifilament yarn by friction, which propagates counter to the yarn running direction in the yarn so that the twisted yarn can be heated and fixed in a so-called false twist zone.
- twist stop devices are used, which have per thread a twist roll with a trained on the circumference zig-zag threadline track.
- twist stop device is known, for example, from DE 1 158 422.
- the twist-stop roller is formed from two discs which overlap each other with axially projecting webs, so that a zigzag-shaped thread running track is formed between the two discs.
- the discs are rotatably connected via a retaining bush with a shaft.
- the rotatably mounted shaft can be driven or freely rotatable.
- the twist stop device is used with a non-driven spin stopper roll. The twist stopper is moved exclusively by the running thread.
- EP 0 460 799 A1 discloses a twist stop device in which the twist stop roller is mounted rotatably directly at the end of a shaft. Such a bearing is very unfavorable with relatively small swirl stop rollers, since only very small and in their life limited shelf life come into question.
- twist stop device known from US Pat. No. 6,408,608 B1 likewise has a swirl stop roller mounted directly on a shaft end, which leads to the known disadvantages.
- a twist stop device in that the bearing end of the shaft is rotatably supported within a bearing bush and that the bearing bush with mounted shaft and spin stop roller can be detachably connected to a roller carrier as a structural unit.
- the invention has the particular advantage that the dimensions of the bearing bush for receiving the bearing of the shaft can be selected independently of the size of the swirl stopper roller.
- the rolling elements necessary for the bearing of the shaft can thus be arranged directly between the bearing bush and the circumference of the shaft.
- the twist stop device can advantageously be held as a unit via the bearing bush in a roller carrier.
- the bearing bushing has a cylindrical sleeve which can be inserted and retained substantially free of play in a receiving opening of the roller carrier. For a simple quick replacement of the entire twist stop is possible.
- the development of the invention is particularly advantageous in which the ceramic discs are held on the circumference of a retaining bush and that the retaining bush is releasably connected to the holding end of the shaft.
- the attachment of the retaining sleeve on the shaft end of the shaft can be made preferably via an inwardly projecting clamping collar, which is clamped by a clamping means directly to the front side of the shaft end.
- a clamping means in this case a screw can be used, wherein for fixing the shaft, these preferably have on the end face of the opposite bearing end a tool holder, in which a holding tool can be inserted.
- the bearing end of the shaft facing away from the ceramic disc is preferably protected by an outer protective plate against damage, which is formed with respect to the ceramic disc with a protective edge radially protruding. This makes it possible in particular to avoid damage during application by a manually guided suction gun.
- the bearing bush is preferably closed at the end faces, each with a lid.
- Fig. 1 shows schematically a cross-sectional view of an embodiment of the
- FIG. 2 schematically shows a side view of the exemplary embodiment from FIG. 1.
- the twist stop device has a shaft 2.
- the shaft 2 protrudes with a bearing end 2.2 in a bearing bushing 5.
- a plurality of rolling elements 6 are arranged between the circumference of the shaft 2 and the bearing bush 5.
- the bearing bush 5 has at its end faces in each case a lid 18.1 and 18.2.
- the cover 18.2 is annular and extends between the inner diameter of the bearing bush 5 and the circumference of the shaft 2. Outside the bearing bush 5, the shaft 2 projects with a holding end 2.1.
- the swirl stop roller 1 is held at the holding end 2.1.
- the swirl stopper 1 has for this purpose two ceramic discs 3.1 and 3.2.
- the ceramic discs 3.1 and 3.2 have on one side on the circumference distributed a plurality of webs 4, which are held overlapping each other. Between the ceramic discs 3.1 and 3.2, a thread running track 19 is formed, wherein the thread in the wrap-around area of the twist stop roller 1 zig-zag-fö 'is guided through the webs 4.
- the ceramic discs 3.1 and 3.2 are held by a Zentrieraufhahme on the circumference of a retaining sleeve 10.
- the retaining sleeve 10 is cup-shaped and has an inwardly projecting clamping collar 11.
- the cup-shaped retaining sleeve 10 is attached to the bearing end 2.2 of the shaft 2.
- a clamping means 12 is provided in the form of a screw, the front side in the holding end 2.1 of the shaft 2 is screwed while the clamping collar 11 of the retaining sleeve 10 with the holding end 2.1 of the shaft 2 clamped.
- the swirl stop roller 1 On the side facing the bearing end 2.2, the swirl stop roller 1 has a support disk 14 which is firmly connected to the ceramic disk 3.2.
- the support plate 14 has an axially outstanding protective collar 15, which partially overlaps the bearing bush 5 in the axial direction with its free end.
- the twist stop roller 1 On the side facing away from the bearing end 2.2, the twist stop roller 1 has a
- Protective disk 16 which is fixedly connected to the ceramic disk 3.1.
- the protective disk 16 extends in the radial direction with a protective edge 17 via the circumference of the ceramic disc 3.1 addition and thus provides an edge protection for the ceramic disc 3.1.
- the protective disk 16 and the ceramic disk 3.1 have on their circumference a cutout 21 which extends as far as a groove base of the ceramic disks 3.1 and 3.2, as shown in FIG.
- the cutout 21 is used to introduce an auxiliary tool, for example, to remove a filament winding from the twist stopper roll 1.
- the support disk 14 on one side of the swirl stopper roller 1 and the protective disk 16 on the opposite side of the swirl stop roller 1 are connected to a plurality of screws 20 and fixed with the ceramic disks 3.1 and 3.2.
- the twist stop device is held on a roller carrier 7.
- the twist stop device is designed as a structural unit and is held via the bearing bush 5 in a receiving opening 8 of the roller carrier 7.
- the bearing bush 5 has a fitting jacket 9 which can be inserted without play in the receiving opening 8.
- the entire twist stop device can thus be connected by inserting or removing the bearing bush 5 from the Aufhahmeöfrhung 8 with the roller carrier 7.
- the roller carrier 7 is hereby preferably firmly integrated in a machine frame.
- a running thread is guided in the thread running track 19 with partial looping on the twist stop roller 1.
- the twist stop roller 1 is driven via the thread, so that the shaft 2 rotates with the twist stop roller 1.
- balls are preferably used as rolling elements 6 in the bearing bush 5 in order to obtain as low-friction as possible storage.
- the shaft 2 on the front side of the storage of 2.2 has a tool holder 13.
- the lid 18.1 on the end face of the bearing bush 5 an opening through which a holding tool in the tool holder 13 can be introduced. With the holding tool can thus fix the shaft 2 in position, so that the clamping means 12 is disassembled.
- the retaining sleeve 10 can be deducted from the holding end 2.1 of the shaft 2.
- the twist stop device according to the invention is particularly suitable for limiting the return of a false twist in the thread in a false twist texturing machine. Since thread-guiding parts usually count as wearing parts in a false-twist texturing machine, the twist-stop device according to the invention is particularly suitable for being able to make a flexible and rapid change when the bearing or the ceramic disks wear out.
