Description

  The present invention relates to a texturing machine having a large number of machining points arranged side by side as described in the front part of claim 1.

  During the production of synthetic yarns, the yarns produced in the melt spinning process are crimped in subsequent processes, especially for textile use. This process is known in the industry under the concept of “texturing”, where the synthetic yarn is drawn simultaneously in the texturing process. Such a texturing process is performed using a texturing machine having a large number of processing points. At least one yarn at each processing site is processed by the texturing assembly. At this time, the yarn is drawn in the texturing zone, textured, and wound on a package after texturing. Process assemblies such as, for example, texturing assemblies, feeding units, heating devices, cooling devices and winding assemblies are arranged in the machine cross section with respect to the predetermined yarn path inside the machining site. At this time, in the prior art, basically, texturing machines of two different structural types are known.

  For example, in the first type of construction known from DE 3719048, the heating and cooling devices are arranged at an angle with respect to the cross-machine plane inside the texturing zone. Yes. This makes it possible to realize a texturing zone which is elongated for a relatively long time at a slight structural height of the machine. However, this known texturing machine has the disadvantage that the yarn must pass through a plurality of turning sections between feeding units within the texturing zone. Such turning is then particularly critical to obtain an unimpeded return of false twist in the yarn produced by the texturing assembly.

  For example, in a texturing machine of the second construction type known from DE-A-3801506, the heating device and the cooling device at the processing location are combined with a supply unit to form a texturing zone. It is arranged in one machine crossing plane. As a result, a long texturing zone can be realized. For this purpose, the heating and cooling devices are preferably arranged in the superstructure of the machine, however, such an arrangement basically makes the operability of the process assembly difficult. Furthermore, in order to be able to accommodate such texturing machines with a large number of machining points, a corresponding machine shop with a large chamber height is required.

  The object of the present invention is therefore to improve a texturing machine of the type mentioned at the outset, on the one hand a suitable yarn runway is ensured in the texturing zone and on the other hand an efficient operation of the process assembly is possible. It is to provide a texturing machine.

  Another object of the present invention is to achieve as compact an arrangement of process assemblies as possible.

  In order to solve this problem, in the texturing machine according to the present invention, a straight yarn path between yarns, between the heating device and the yarn inlet of the cooling device, and between the texturing assembly and the yarn outlet of the cooling device. A cooling device is formed between the texturing assembly and the heating device inside one of the processing points so that it can be guided between them.

  Preferred embodiments of the invention are defined by the features and combinations of features of each dependent claim.

  The present invention is distinguished by the fact that the yarn can be guided inside the texturing zone at every machining point, without large turnings and without an additional yarn guide. In this way, the centrifugal force on the filament of the yarn can be applied uniformly. Furthermore, unwinding (Drallrueckfuehrung) in the yarns necessary for texturing is possible without weakening due to the deflection of the yarns. By appropriately arranging the heating device and the subsequent cooling device in the machine longitudinal direction, it is also possible to achieve a relatively slight machine height, in particular a relatively short yarn section occurring at the machining site. It is done.

  In order to construct the transition in the yarn path between the process assemblies inside the texturing zone of the machining site as loosely as possible, in a preferred embodiment, the cooling device is provided with a curved cooling rail at the corresponding machining site. Is formed. With this arrangement, the yarn inlet of the cooling device and the yarn outlet of the cooling device can be optimally adapted to the front process assembly and the rear process assembly. And the deviation between the texturing assembly and the heating device outlet acting transversely to the cross machine plane can be suitably compensated for without additional yarn guide elements by shaping the curved cooling rail. it can.

  In the aspect which can further improve the uniformity with respect to the processing of the yarn at the processing location, the heating device and the cooling device at the processing location are located on one common yarn path plane. With this construction, it is possible to achieve the same yarn guide with a very short yarn section between the individual process assemblies at the respective machining locations.

  In an embodiment in which the yarn processing in the texturing zone can be further improved at this time, the texturing assembly and the feeding unit after the texturing assembly are arranged together in the yarn runway plane. With this configuration, the yarn can be guided through the entire texturing zone between the supply units in a substantially straight yarn path inside the machining area.

  In order to obtain a compact arrangement of the process assembly inside the texturing machine, in another preferred embodiment of the invention, the yarn runway plane of the texturing zone at the processing site is perpendicular to the machine center plane. Oriented in parallel. If constituted in this way, what is called a double machine (Doppelmaschine) in which many processing points are formed in contrasting arrangement form located mutually opposed can also be realized advantageously.

  In a further possible embodiment by means of a heating device that is tilted in the machine longitudinal direction, the heating devices are arranged side by side in parallel with a minimum spacing, the minimum spacing being the processing points that are adjacent to each other. It is smaller than the position interval between. With this compact arrangement of the heating device, an energy-friendly and suitable arrangement of the heating device can be selected. For example, multiple heating devices can be incorporated together in a single insulating housing.

  The spacing between adjacent heating devices is directly related to the inclination level of the heating device. In order to achieve as compact an arrangement of the heating devices as possible on the short yarn path, in another particularly preferred embodiment of the invention, the feeding unit comprising the texturing zone has a mechanical offset of at least 1 m. . When configured in this way, the inclination of the heating device and the length of the texturing zone can be brought to a suitable ratio for realizing a compact and particularly energy-saving arrangement.

  In another aspect of the invention, which can have a particularly favorable influence on the operability of the process assembly, the supply unit, the heating device, the cooling device and the texturing assembly are operable from the floor in the machine frame. Is retained. Preferably, subsequent supply units are held in the lower region of the machine frame, so that the operator can set up the yarn from the operating path to all process assemblies at the start of the process.

  The texturing machine according to the invention is basically independent of the respective automation level of the winding assembly. For example, the texturing machine according to the present invention may comprise a winding assembly in which the package is automatically wound, or may comprise a winding assembly in which the package is wound manually.

  Next, an embodiment of a texturing machine according to the present invention will be described in detail with reference to the drawings.

1 is a cross-sectional view schematically showing an embodiment of a texturing machine according to the present invention. FIG. 2 is a side view partially and schematically showing the embodiment shown in FIG. 1. FIG. 2 is a plan view partially and schematically showing the embodiment shown in FIG. 1.

  1 to 3 show a first embodiment of a texturing machine according to the present invention for texturing a large number of yarns from various viewpoints. FIG. 1 shows the present embodiment in a cross-sectional view, and FIGS. 2 and 3 show a part in a side view and a plan view, respectively. In particular, unless one of the drawings is designated, the following description is for all drawings.

  This embodiment of the texturing machine has a large number of machining locations, and a plurality of these machining locations are arranged side by side. For example, more than 100 machining points may be arranged side by side along the machine long side. In FIGS. 1 to 3, only the first three machining points are indicated by reference numerals 1.1, 1.2 and 1.3.

  Each machining location 1.1-1.3 has a plurality of process assemblies, which are held in a machine frame consisting of a plurality of parts. In this embodiment, the machine frame 2 includes a process frame 2.1 that accommodates a process assembly, a winding frame 2.2 that accommodates a plurality of winding assemblies, and a process frame 2.1 that is a winding frame 2. 2 is formed by a cross beam 2.3 coupled to 2. An operation passage 6 is formed between the process frame 2.1 and the winding frame 2.2.

  Since the structures of the processing points 1.1, 1.2, and 1.3 are the same, in the following, the process assembly will be described in detail using the yarn path at the processing point 1.1 with reference to the illustration in FIG. To do.

  At the processing point 1.1, first, the yarn 18 is pulled out from the supply package 16 by the first supply unit 8, and at this time, the yarn is guided through a plurality of guide rollers 13. The supply package 16 is held by the creel frame 3, which is arranged beside the process frame 2.1 on the machine long side 5. A reserve package 17 is disposed in correspondence with the supply package 16 inside the creel frame 3. The machine long side 5 extends in a direction perpendicular to the drawing plane of FIG.

  The first supply unit 8 forms a so-called texturing zone 7 together with the second supply unit 21 placed later, in which the yarn 8 is stretched and textured. The first supply unit 8 and the second supply unit 21 are held in the process frame 2.1. Inside the texturing zone 7 formed by the supply units 8, 21, a heating device 9, a cooling device 10 and a texturing assembly 11 are arranged in succession in the yarn traveling direction. The texturing assembly 11 is arranged in the process frame 2.1 just above the second supply unit 21.

  In order to maintain the maximum operating height and to achieve a relatively long texturing zone, the heating device 9 and the cooling device 10 are tilted in the machine longitudinal direction and held in the process frame 2.1. In order to explain the texturing zone and to explain the arrangement of the heating device 9 and the cooling device 10, reference is additionally made to FIGS.

  FIG. 2 shows a part of the process frame 2.1 in a side view. FIG. 3 shows the operation passage 6 in a plan view.

  As can be seen from the illustrations of FIGS. 2 and 3, the heating device 9 and the cooling device 10 form one common yarn runway plane, at which time the yarn is fed into the first supply unit 8 and the texturing assembly 11. Between and without any additional yarn guide elements and thus without any turning in the yarn runway.

  As can be seen in particular from the illustration in FIG. 2, the heating device 9 at the machining location 1.1 is arranged at an angle with respect to the cross-machine plane 4. This angle is indicated by the symbol α and is preferably in the range of 30 ° to 70 °.

  In the yarn running path, the yarn inlet 25 of the cooling device 10 is directly arranged corresponding to the heating device 9 so that the yarn can run into the cooling device 10 in the yarn running path where the yarn is straight. The cooling device 10 then has substantially the same angular position with respect to the cross machine plane 4.

  In order to be able to guide the yarn to the texturing assembly 11 with as little deflection as possible, the yarn outlet 26 of the cooling device 10 is arranged directly above the texturing assembly 11 so that the yarn is textured with the yarn outlet 26. It is guided without turning between the ring assembly 11. In order to continuously guide the yarn inside the machining location 1.1 and to overcome the mechanical misalignment inside the machining location 1.1, the cooling device 10 in this embodiment is a curved cooling rail. 24. This configuration is advantageous because the spatially offset process assemblies can be coupled together without additional guide elements.

  2 and 3, the heating device 9 and the cooling device 10 together with the texturing assembly 11 and the second supply unit 21 form one common yarn path plane. The yarn path planes of the texturing zone are each oriented in the vertical direction in parallel with the machine center plane 31 at the machining location. The machine center plane 31 extends perpendicular to the machine crossing plane 4. This makes it possible to arrange all the process assemblies in the process frame 2.1 very compactly. At this time, the heating devices 9 at the machining points 1.1 to 1.3 are arranged in parallel with each other at a minimum interval. It is smaller than the position interval between 1.2. In FIG. 2, the minimum distance between the two heating devices 9 adjacent to each other is indicated by a symbol H. For example, the position interval between the two adjacent processing points of the yarn outlet of the cooling device 10 is This is indicated by the symbol S. This makes it possible to arrange the heating device 9 in the insulating housing in an energetically favorable manner. In relation to the inclination angle α of the heating device 9 and the cooling device 10 in the machine longitudinal direction, a shift occurs in the machining location 1.1 between the first supply unit 8 and the second supply unit 21. For example, the supply units 8, 21 are arranged in different machine crossing planes. The mechanical deviation (position deviation) between the supply unit 8 and the supply unit 21 at the first machining location 1.1 is indicated by the symbol A in FIG. On the one hand, to obtain a sufficient inclination for a compact arrangement of the heating devices 9 at adjacent processing points, and on the other hand, a sufficient length of the texturing zone to achieve a high yarn processing speed. Therefore, it is desirable to maintain a mechanical deviation of at least 1 m. If the machine deviation is relatively small, a relatively large operating height is required, and such an operating height partially requires the superstructure of the machine.

  As can be seen from the illustration in FIG. 1, in a further transition, the yarn 18 is guided to the entanglement device 15 and then through the after-heating device 14 between the third supply unit 22 and the fourth supply unit 23. Guided. The post-heating device 14 forms a post-treatment zone, whereby a relaxation treatment on the yarn 18 can be carried out at a low yarn tension adjustable between the supply unit 22 and the supply unit 23.

  The after-heating device 14 and the third supply unit 22 are additionally used only for the case of yarn aftertreatment. For the case where it is not necessary to add post-processing to the yarn material, the processing point 1.1 is configured without the post-heating device 14 and the third supply unit 22.

  As is apparent from the illustration in FIG. 2, the post-heating device 14 is similarly held in the process frame 2.1 while being inclined in the machine longitudinal direction. The post-heating device 14 is preferably tilted in the same direction as the heating device 9. In principle, however, it is also possible to arrange the post-heating device 14 parallel to the cross-machine plane 4.

  As can be seen from the illustration in FIG. 1, a winding assembly 12.1 is provided at the end of the machining location 1.1, and the yarn 18 is wound around the package 19 by this winding assembly 12.1. For this purpose, the winding assembly 12.1 at the machining location 1.1 can be arranged, for example, directly in the upper region of the winding frame 2.2.

  The winding frame 2.2 is directly connected to the process on the side located opposite the operation passage 6 in order to accommodate the winding assemblies 12.1 to 12.3 of the processing points 1.1 to 1.3. Corresponding to the frame 2.1. The winding frame 2.2 forms the second machine long side 5. The winding assemblies 12.1 to 12.3 are arranged one above the other in a hierarchical manner. For example, the width of one winding assembly is usually several times larger than the position spacing between adjacent machining points 1.1, 1.2 in the process frame 2.1. In this way, a compact structure form of the texturing machine can be realized by the hierarchical arrangement form. The winding assemblies 12.1 to 12.3 shown in FIG. 1 at the machining locations 1.1 to 1.3 and the adjacent winding assemblies at the adjacent machining locations are configured identically, and the yarn 18 Is wound around the package 19. The package 19 formed in the winding assemblies 12.1 to 12.3 is taken out from the operation passage 6 and carried out.

  As can be seen from the illustration in FIG. 1, all the operating steps for initial setting of the yarn or at the time of yarn breakage in the process assembly can be carried out by the operator from the operating passage 6. For this purpose, in particular, the supply units 8, 21, the heating device 9, the cooling device 10 and the texturing assembly 11 held in the upper region of the machine frame are configured to be operable from the floor without auxiliary means. Since the winding assemblies 12.1 to 12.3 are partially automated, the operation for changing the package can also be performed from the operating channel 6 by the operator.

  For conveying and stretching, the supply units provided at the processing points 1.1 to 1.3 are partly formed as so-called nip supply units (Klemmlieferwerk) or as winding supply units (Umschlingungslieferwerk). . In the nip type supply unit, the conveying force is transmitted by nipping the yarn. In the winding supply unit, the necessary conveying force is generated by winding the yarn several times. In particular, it has been found that it is preferable to configure the supply unit 23 arranged upstream of the winding assemblies 12.1 to 12.3 as a nip-type supply unit. As can be seen from the illustration in FIG. 2, the nip type supply unit has a pressing roller 27 for each processing portion, and this pressing roller 27 is in contact with the periphery of the driven shaft 28. The shaft 28 is driven via a motor 29. At this time, the shaft 28 is held by the machine frame 2 via a plurality of bearing bases 30.

  The supply units 8 and 21 arranged corresponding to the texturing zone 7 are configured as winding supply units, and are formed of, for example, a driven godet and an additional corresponding guide roller (Ueberlaufrolle). In the present embodiment, the first supply unit 8, the second supply unit 21, and the third supply unit 22 at the processing location 1.1 are configured as a winding supply unit.

  To emphasize and describe here, the arrangement and configuration of the yarn guide element and the process assembly in the embodiment shown in FIGS. 1 to 3 are an example. Thus, the supply unit can be varied in any combination between the wound supply unit and the nip supply unit.
