Definitions

  • the invention relates to a splice unit for a pneumatic splicer, a splicer containing such a splice unit and a textile machine with such a splicer.
  • a splicer is understood to mean a device for connecting two thread ends, wherein here and below a thread is always intended to mean a structure consisting of twisted individual fibers.
  • the thread connection is made by inserting the threads to be joined through an insertion slot in a splice of the splicer, then injected with at least one therein inlet channel compressed air, which mixes the fibers of the threads together and twisted, so that one of the other thread structure in appearance and strength similar connection arises.
  • compressed air or splicing air is used here representative of all suitable connection media, so in addition to pure ambient air in particular also humidified air.
  • the insertion slot can be covered by a splice lid after inserting the threads.
  • the top and bottom openings of the splice channel can be narrowed by directly adjacent control plates, or the outflow of the splicing air can be suitably influenced there by spaced from the top and bottom surfaces control plates. Often these control plates also take over thread guiding functions when inserting the threads into the splice channel and are then also called thread guide plates.
  • Near the top and bottom surfaces of the splice channel may alternatively or in addition also thread holding levers are used, sometimes referred to as Fadenand Weghebel or locking fork, which limit the mobility of the threads directly outside the splice.
  • the injection of the splicing air also leads to the rotation of the threads above and below the splice channel and thus to the formation of two thread balloons which pull the threads from the splice channel if the diameter is too large.
  • a barrier fork limits the diameter of these balloons.
  • the DE 36 122 29 C2 also describes in addition to the just mentioned control plates and Fadenandrückhebeln a split in the axial direction in two radially staggered splice splice.
  • Each splice chamber has its own inlet channel for the splicing air opening tangentially into it, which generates eddy currents directed in opposite directions in the chambers.
  • the DE 102 02 781 A1 discloses an insert of the yarn return nozzles located above and below the splice channel as holding elements of the filaments until the initiation or even shortly after the initiation of the splicing operation.
  • holding and Auflöserschreibchen Fadenendeschwinddüsen in the immediate vicinity and suitable geometric arrangement attached to the axial splice channel exits, and their thread-side openings are funnel-shaped.
  • the suction air is turned off in the holding and Auflöserschreibchen only the first injection of the splicing or even shortly thereafter, so that the holding and Auflöserschreibchen exert until then a secure holding function on the threads.
  • the axial subdivision of the splice channel into two radially offset splice chambers also offers the possibility of providing separate inlet channels for the splicing air in both chambers, which can then generate mutually opposing eddy currents in the chambers.
  • the radial offset of the chambers ensures a certain decoupling of these flows, since the impact surface between the chambers is reduced thereby.
  • Another resistance to the splicing air caused by the axial pushing out of the threads from the splice channel can be achieved by an inclination of the splice channel relative to the adjacent thread profile.
  • a winding unit an automatic winder, in which the splicer can be used, erected in a vertical design, so the thread runs, for example, from the bottom mounted delivery bobbin substantially vertically upwards to the package.
  • the splice would then be inclined to the vertical, with a minimum inclination angle of 20 ° being particularly preferred.
  • the geometry and mutual position of the thread insertion slot and the tangential opening area can be designed such that the injected splicing air is directed in the thread insertion direction.
  • the vortex flow at the thread insertion slot conveys the threads radially into the interior of the splice channel, since there are no practically relevant flow components which extend radially out of the thread insertion slot.
  • splicer covers and / or locking forks are additionally possible.
  • a pivotal base receptacle to which then alternatively a lid lever with splicer cover or a locking fork, for example with a screw or a snap connection, are attached. This allows, with relatively little financial and labor expense, the use of such simple accessories without having to remove the splicer as such from a textile machine in which it is used.
  • the control of the valves in the corresponding compressed air lines is to be designed so that the pressurization of the holding and Auflöserschreibchen is terminated at the earliest with the onset of splicing.
  • This control can, as is common today, in the workstation computer, for example, the winding unit, in which the splicer is used, are housed. But also possible is a central control by the central computer of the textile machine.
  • FIG. 2 shows in a perspective view of the splicer 10 Fig. 1
  • the suction nozzle 12 has just brought back the upper thread 31 of the cheese 15 and inserted into the splice 20 of the splice head 19, while the gripper tube 25, the lower thread 32 from Spinnkops 9 and has also inserted into the splice channel 20.
  • the upper thread 31 is also threaded into the clamping element 11 'of the upper thread clamping and cutting device 11 and into the cutting element 17 "of the bottom arranged Fadenklemm- and cutting device 17.
  • the lower thread 32 is in the clamping element 17' of the lower thread clamping and cutting device 17 and in the cutting element 11 "of the upper thread clamping and cutting device 11.
  • the further production of the splice takes place in a basically known manner.
  • the upper clamping element 11 clamps the upper thread 31, which is cut to length by the lower cutting element 17 ", and accordingly the lower clamping element 17' clamps the lower thread 32, which is cut to length by the upper cutting element 11".
  • the thread ends are dissolved by pressurized air in the holding and Auflöserschreibchen 18 and prepared for splicing together.
  • the actual splice is made by injecting the spliced air into the splice channel 20.
  • the feeder 30 ensures the movement of the thread ends of upper thread 31 and lower thread 32, which is necessary in between.
  • FIG. 3 shows in its left part a splice channel unit 60 according to the invention in a perspective view, as it is from a viewing direction from the front and slightly obliquely from above. Essentially, therefore, one looks straight onto the thread guide surfaces 61 leading to the thread insertion slot 62 and recognizes the upper axial exit 63o of the splice channel 20 well through the viewing angle from slightly obliquely above.
  • the same splice channel unit 60 is again shown in a similar view, but with the viewpoint now higher up.
  • FIG. 5 shows a further perspective inside view of the splice channel unit 60 according to the invention FIG. 3 ,
  • the perspective of the perspective view is from above and slightly from behind.
  • Splice channel unit 60 is cut slightly below its center with respect to its height.
  • the cutting plane is inclined on the left side in the figure down and back. Again, then all components are omitted in front of the cutting plane and the remaining components are displayed transparently.
  • This embodiment of the inlet channel 66u in the only two bores of their parts 67u and 68u and 69u is easy to manufacture.
  • the flow conditions during injection The splicing air is not optimal due to the strong deflection at the lower closure pin 64u, but is acceptable in practice given a suitable choice of bore diameter.
  • the flow distribution should be as free from turbulence as possible, largely any desired design of the inlet channel can be realized by casting techniques for the splice channel unit, thereby further completely avoiding even any leakage problems with the closure pins 64o and 64u.
  • An alternative embodiment of this embodiment of the invention which leads to similarly optimal flow conditions in the lower splice 20u, is not to specify the specific dimensions of the mouth-side inlet channel part 69u, but to give the designer here more freedom regarding channeling and its design, where he However, care must be taken that the splicing air at the latest before the mouth 70u of the lower mouth-side inlet channel part 69u forms a laminar flow directed into the lower splice chamber 20u.
  • Such a laminar and suitably directed flow also ensures good mixing and subsequent twisting of the fibers of upper thread 31 and lower thread 32 and thus to a high-quality splice.
  • the laminarity of the flow also prevents Energy losses through turbulence and thus ensures optimal energy use of the compressed air generator.
  • downstream side lower intake passage part 69u is disposed opposite to the lower splice chamber 20u so that the splicing air flows tangentially in the circumferential direction of the cylindrically shaped lower splice chamber 20u.
  • the inlet channel part 69u opens in the immediate vicinity of the FadeneinGermanschlitzes 62 and is directed so that the splicing air fully introduced in Fadenein technological conference 72 fibers of upper thread 31 and lower thread 32 fully and they continue the Fadenein technological puzzle 72 in the vortex 71u and thus into the interior of the lower Pulling splice chamber 20u, wherein the fibers are intimately mixed and twisted.
  • the splice channel unit 60 is essentially made of a single workpiece, so it is made in one piece. Only the outer sides of the holes for the inlet channels 66o and 66u are closed by separate closure pins 64o and 64u. This one-piece design allows, in addition to sufficient for the desired inlet channel design size still a compact design and good dimensional stability by minimizing the tolerance chains and a high density of compressed air supply.
  • FIG. 6 shows in its left main part a cross section through the two-part splice channel 20 of the splice unit 60 according to the invention, which cross-section contains both the splice axis 74 and the axes 76 and 77 of the upper and lower splice 20o and 20u.
  • the diameter of each of the upper and lower splice chambers 20o and 20u is entered.
  • the essential element of the present invention is the sufficiently sharp formation of the abutting edges 20SKo and 20SKu of the upper and lower splice chambers 20o and 20u. This is shown in detail 79 of the right of her main body FIG. 6 shown.
  • the radius of curvature 80 of the upper and lower abutting edges 20SKo and 20SKu must be greater than 0 mm and less than 0.35 mm.
  • a splice channel unit 60 can also be combined with the other constructive measures known from the prior art for optimizing the splicing process.
  • splicer covers, control plates / thread guide plates and / or locking forks can be used.
  • FIG. 7 shows three variants of such combinations.
  • a splicer 10 with a splice channel unit 60 according to the invention whose splice channel 20 leading Fadenein Industriesschlitz 62 is clearly visible in the left and right variants shown, while it is closed in the middle variant of a splicer cover 23.
  • All three variants also have thread guide plates 81 mounted on the splice channel unit 60.
  • the splice channel unit 60 for better thread guidance also with the in FIG. 3 shown leading obliquely to Fadenein Industriesschlitz 62 Fadenleit vom 61.
  • the middle variant with the cover by the splicer cover 23 is a splice unit 60 with a cheaper for such a cover and in FIG. 2 used shown smooth front.
  • this has in the FIG. 7 a pivotable about an axis of rotation 82 base receptacle 83.
  • This has a drive lever 83b (only in the left part of FIG. 7 referred to), to which at the installation of the splicer 10 in the winding unit 2, possibly via a transmission linkage, a drive is connected.
  • a receiving lever 83 a which, if there is no need, can remain free (left part of the figure), or to either a cover lever 85, a splicer cover 23 (middle part of the figure) or directly a locking fork 86 (right part the figure) each by means of a screw 84 can be attached.
  • the base receptacle 83 thus provides a simple way to operate the splicer 10 in different variants without triggering large conversion effort.
  • other and also tool-less fastening systems such as, for example, Snap connections conceivable, and instead of a receiving lever 83a may e.g. also a slide-in system can be selected.
  • splice channel unit according to the invention has been described in the foregoing only in certain variants, it is clear to the person skilled in the art that the individual embodiments can be largely freely combined with one another and used individually, and further variants are possible. So, for example, no specially designed inlet channel for the splicing air are used, but the inventive sharp design of the abutting edges of the splice chambers provides for many situations already alone for the desired improvement of the splicing process.
