Description

  The present invention relates to an apparatus for pulling out and processing a yarn group in a melt spinning process as described in the front part of claim 1.

  Such an apparatus for drawing and processing yarn groups in the melt spinning process is known from DE 103 34 462 A1.

  When producing synthetic yarns in the melt spinning process, fine filament strands are extruded from the polymer melt and are each combined into one multifilament yarn after cooling. At this time, usually, a plurality of yarns are drawn out from the spinning device as one yarn group and guided to a further processing step. The gathering of the filaments into yarn is preferably ensured by a wetting agent applied to the filament strands immediately after cooling. Since the yarn bundle produced by such an oil agent is insufficient for further processing, the yarn is entangled with compressed air in a separate processing step before winding.

  As is known from German Offenlegungsschrift 10 343 462, the processing steps for entanglement of the yarn are preferably carried out between two driven godets. The entanglement device is therefore arranged between two godets driven on the yarn runway and has a separate treatment path for each multifilament yarn. Such treatment of the yarn with compressed air results in the floating component of the yarn being partly carried out of the treatment path of the confounding device by the blow-off flow in relation to the respective working pressure of the confounding device.

  Therefore, in order to avoid a very heavy load on the surroundings, for example, a known entanglement device according to WO 2009/013107 is arranged in one housing together with an oil supply device. Suspended components, preferably liquid residues, collected in the housing are discharged via the suction connection. Although this known apparatus requires a combination of processing steps for wetting the yarn and for interlacing the yarn, both processing steps are often performed at completely different points in the melt spinning process.

  However, in the device known from DE 10006196 A, a plurality of godets and a plurality of confounding devices are arranged together in one housing, in which a floating component generated by confounding Is absorbed and sucked out by suction. However, with this configuration, there arises a problem that all members arranged in the housing, that is, godets are also arranged in an environment that receives a load due to floating components.

  The object of the present invention is therefore to improve the device for drawing and processing the yarn group of the type mentioned at the outset so that as little contamination as possible is possible around the confounding device.

  In order to solve this problem, in the configuration of the present invention, a suction pipe piece is disposed on the outlet side of the entanglement device, and the suction pipe piece has a suction opening at a free end and is on the opposite side. At the end located at the end, it is connected to the suction device.

  Further aspects of the invention are defined by the features and combinations of features described in each dependent claim.

  The invention stands out because the blown air generated from the treatment passage is directly absorbed and discharged at the outlet side of the entangling device. Depending on the configuration of the suction pipe piece, the suction pipe piece can be arranged below, above or at the height of the yarn path plane. Thereby, the blowing flow generated on the outlet side of the entanglement device can be continuously absorbed and discharged.

  In the compressed air treatment of the multifilament yarn inside the treatment passage, only a part of the blown air reaches the outlet side. Therefore, in a particularly preferable aspect of the present invention, the second suction pipe piece is provided on the inlet side of the entanglement device. Arranged, the second suction pipe piece has a suction opening at the free end and is connected to the suction device at the opposite end. With such a configuration, it is possible to absorb and discharge the blow-out flow directed to the yarn running path in the processing passage on the inlet side, which is preferable. Even in such an embodiment, suction around the yarn is possible according to the structural configuration of the suction pipe piece.

  In order to be able to produce a concentrated suction action on the outlet side and / or on the inlet side even when there are a large number of yarns and thus even when there are a large number of treatment paths in the entanglement device, In another aspect, the suction opening of the suction pipe piece on the outlet side and / or the suction opening of the suction pipe piece on the inlet side has a protruding suction trough, and the suction trough includes a plurality of processing passages of the confounding device. Extending along a plurality of outlet openings or along a plurality of inlet openings in the process passage. With this configuration, the suction action can be adjusted depending on the number of outlet openings and inlet openings in the processing passage.

  In a particularly preferred manner, the suction pipe piece is formed by a pipe member, which has a notch in the region of the suction trough, said pipe end being defined by a pipe bottom at the free end. ing. If comprised in this way, the thread | yarn guide located on a suction trough in the immediate vicinity of a suction opening at a slight space | interval is realizable. Thereby, the circumference | surroundings of a thread | yarn can be sucked especially strongly.

  For yarn guidance, a plurality of running-side yarn guides are correspondingly arranged at the outlet opening of the processing passage, and these running-side yarn guides are arranged together on the holding metal sheet. However, in order to obtain a uniform suction action at the outlet opening of the processing passage, the holding metal sheet is formed with a plurality of through openings between the suction trough and the outlet opening.

  A corresponding configuration can also be realized on the inlet side of the entanglement device, so that a plurality of threading side yarn guides are held by the holding metal sheet between the suction trough and the inlet opening of the processing passage. Sometimes the holding metal sheet has a plurality of through openings.

  In order to directly absorb the blow-off flow generated through the outlet opening and / or the inlet opening of the confounding device, in a preferred embodiment of the invention, a suction pipe piece on the outlet side and / or a second suction pipe piece on the inlet side are used. Is formed as a suction box in a box shape, where the suction opening is formed on the long side of the suction box, and the outflow opening connected to the suction device is formed on the end face side of the suction box .

  The deflecting device for turning the blow-out flow entering the suction pipe piece through the suction opening toward the outflow opening is preferably formed by a plurality of air guide metal thin plates, and these air guide metal thin plates are inclined. And is distributed and held on the long side of the suction box. In this way, the blow-out flow that directly enters the suction opening can be turned toward the outflow opening.

  In order to be able to suck in the entanglement device as large as possible around the yarn, in another aspect of the invention, the outlet opening of the suction box opens into the suction opening, which is the outlet opening. Larger opening cross section. Thereby, a part of the suction opening can be directly connected around the confounding device.

  Such an embodiment is particularly suitable for the case where the entanglement device is arranged in one godet box.

  In order to be able to draw in as much of the blowing flow as possible in the entanglement device despite the yarn movement, the entanglement device further comprises a holding body and a longitudinally arranged on the upper side of the holding body. Nozzle blocks, the nozzle blocks having process passages located side by side, wherein the holding body has one flow profile on at least one side of the nozzle block, a suction box Toward the suction opening. As a result, the so-called Coanda effect makes it possible to turn the blown flow directly toward the suction opening.

  In order to guide and stabilize the yarn, a plurality of yarn guides are provided on the outlet side and the inlet side, respectively. In order not to prevent the blow-in flow from entering the suction opening, the running-side yarn guide is further held by the holding metal thin plate, the holding metal thin plate is fixed to the holding body, and the holding body A plurality of through-openings at the end of the flow contour. Thereby, on the one hand, the free yarn part can be limited to a minimum length when the yarn is entangled, and on the other hand, the blow-out flow can be continuously supplied to the suction opening.

  For the case where the inlet opening is similarly sucked through the suction pipe piece, the installation of the running-side yarn guide is equivalently formed, so that continuous suction of the blow-out flow is also possible on the inlet side. .

  In a preferred embodiment of the present invention for realizing separation between the periphery of the yarn guide and the electric drive device, the godet, the entanglement device and the suction pipe piece are held by the mounting wall, and at this time, the godet peripheral wall of the godet, The processing path of the entangling device and the suction opening of the suction pipe piece are held on the front side of the mounting wall. If comprised in this way, the isolated thread | yarn circumference | surroundings in the front side of a mounting wall can be implement | achieved suitably.

  In order to limit the influence on the surroundings, in another aspect, the godet peripheral wall, the processing passage and the suction pipe piece are shielded from the surroundings by a cover on the mounting wall.

  At this time, it has been found that it is particularly suitable to form a separate chamber between the godet and the entanglement device if the cover is formed as a profile door. For this purpose, a plurality of partition walls having a thread passage opening are formed inside the deformed door, and at this time, the deformed door is rotatably held on the mounting wall.

  In a mode in which the compactness of the device can be further increased, the yarn entering device is arranged directly corresponding to one of the godets, and is held on the mounting wall inside the cover. As a result, the yarn can be supplied directly from the spinning device.

  In yet another aspect, the mounting wall is located directly on the machine frame of the winder so that the yarn can be fed directly to the winder unit of the winder. For this purpose, one of the godets is held in the region of the end face of the winder.

  Thus, the device according to the invention is particularly suitable for storing yarn groups consisting of a plurality of yarns directly from the spinning device and further supplying them directly to the winder in the melt spinning process. In particular, since the load elements for the surroundings that are generated when the yarn is entangled are absorbed and discharged directly at the generation point, the influence is exerted on the assembly arranged on the upstream side and the assembly arranged on the downstream side. There is no.
