Abstract

A texturing machine is described for texturing and reeling a plurality of threads which is composed of two machine halves. The machine halves are placed against one another in a mirror-image manner and have respectively several operating points with several process units for texturing and reeling several threads. Heating devices thereby face one another in a symmetry plane, which heating devices can be controlled and regulated separately from one another in the machine halves. In order to obtain a compact, space-saving construction and also avoid heat losses, the heating devices of the two machine halves are arranged jointly in the symmetry plane in an insulating housing according to the invention, a heat barrier being embodied inside the insulating housing between the heating devices. Individual settings in the heating devices are thus possible without impacting one another.

Description

texturing

The invention relates to a texturing machine for texturing and winding a plurality of threads according to the preamble of claim 1.

A generic texturing machine is known from WO 98/33963.

The known texturing machine has a multiplicity of processing points in order to simultaneously texturize and wind a multiplicity of threads. For this purpose, the process units such as delivery mechanisms, heaters, cooling devices, texturing and rewinding devices are held in a machine frame. For this purpose, the processing stations and thus the process units are divided into two machine halves, the machine halves being arranged in mirror image with respect to one another. This arrangement allows a relatively high space utilization in order to obtain a favorable ratio between the number of processing points and the space requirement of the machine. The processing points within the machine halves can be operated independently so that the processing units in the machine halves are independently driven and controlled. In the known texturing machine, the plane of symmetry thus constitutes a separation between the machine halves and between the processing units held in the machine halves in order to be able to make individual adjustments in the processing stations depending on the yarn material presented. Such symmetrically designed double machines have long been known in the art and, for example, are already apparent from US 4,581,884.

However, the older texturing machines were designed so that threads with the same parameters and the same process settings are textured and wound up in all processing stations and thus in each machine half. In order to obtain the highest possible integration of the process units of the two machine halves and thus the best possible space utilization, a process unit jointly used by both machine halves was arranged in the form of a heating device in the plane of symmetry. Such heaters have guiding and heating means for simultaneously heating two parallel groups of filaments. This structure and the use of the process units is thus necessarily linked to an equal treatment of all threads in both halves of the machine. However, individual adjustments of the process units within the machine halves can not be realized thereby.

It is an object of the invention to further develop a texturing machine for texturing and winding a plurality of yarns of the generic type such that, despite individual adjustment possibilities of the process units in the machine halves, high integration of the processing units with high space utilization becomes possible.

Another object of the invention is to choose an arrangement of the machine halves, which has the most energy savings possible.

This object is achieved in that the heaters of the two machine halves are arranged in the plane of symmetry together in an insulating and that is formed within the insulating housing between the heaters a thermal barrier. Advantageous developments of the invention are defined by the features and feature combinations of the respective subclaims.

The invention is characterized in that the insulation required for heating devices is substantially reduced in order to avoid heat losses, in which the heating devices adjacent to the machine halves receive a common insulation with respect to the environment. In order to prevent mutual influencing of the tempering of the threads in the mutually opposite processing points of the machine halves within the insulating housing, a thermal barrier is formed between the heating devices. As a heat barrier means are meant that significantly hinder the heat transfer between the heaters. It is essential here that the heat treatment of the filaments associated with the heaters is decisively effected by the relevant heating device and not by the adjacent heating device.

Since the heaters are preferably designed such that at the same time several threads are guided and heated as a group, the development of the invention, in which the thermal barrier extends within the insulating housing substantially over the entire width and entire length of the heaters, sure that none the threads undergoes an unwanted heat treatment by heat emission of a neighboring heater.

In extreme cases, in which one of the machine half without temperature control of the threads and the adjacent machine half is operated with maximum temperature control of the threads, to obtain an unintended mutual interference in the treatment of threads, according to a preferred embodiment of the invention, the thermal barrier between the heaters designed so that when operating only one of the heaters, the threads are heated in the non-activated heater to a maximum temperature of <80 ° C. In order to unwanted thermal changes to the non-tempered threads can be avoided even with maximum heating of the adjacent threads in the adjacent heater.

In a preferred embodiment of the invention, it is proposed to form the thermal barrier by an air gap, which is connected by at least one opening on a bottom of the insulating housing and a further opening on an upper side of the insulating housing with the environment. In this way, essentially two effects can be advantageously realized to avoid heat transfer between the heating devices. On the one hand, it is known that air has a poor heat-conducting property compared to other materials, so that a high insulating effect is achieved by the thermal barrier. On the other hand, the downwardly open air gap leads to the formation of a natural chimney effect, so that an air exchange takes place within the air gap with the environment, which leads to an advantageous heat dissipation. This significantly improves the effect of the thermal barrier.

In order to obtain a uniform air flow acting over the entire width of the air gap, the openings on the lower side and on the upper side are preferably slit-shaped and extend substantially the same size over the width of the air gap.

In cases where the machine halves are operated with substantially equal tempered threads in heaters, the amount of heat discharged through the air gap can be avoided that, according to an advantageous embodiment of the invention, the opening at the top of the insulating housing formed by a movable lid closed is. Thus, depending on the operating state and selected parameters in the machine halves, the thermal barrier can be designed to be highly active with the lid open or reduced with the lid closed.

- A - A very cost-effective and effective insulation of the heaters towards the environment is given by the development of the invention, wherein the insulating two has formed by sheet-shaped housing walls insulating chambers for receiving the heaters, said insulating chambers have at least one insulating material surrounding the heater insulating material and wherein the Heat barrier is arranged between the insulating chambers. This allows unwanted heat losses to the heaters can be reduced to a minimum.

The heaters arranged in the plane of symmetry of the texturing device are preferably used for the so-called shrinkage treatment of the threads, the threads being conveyed into the heating devices with a slight transmission. In order to nevertheless ensure a secure thread guidance and tempering of the threads, the formation of the texturing machine is preferably carried out with heating devices, each of which has a group of heating tubes for heating the threads, wherein the heating tubes are jointly controlled by a respective heating device associated heating means are heated.

As a heating means, a heat transfer medium is preferably used, which is guided by means of a heat carrier circuit to the outer walls of the heating tube. The heat cycles of both heaters are independently adjustable and adjustable up to maximum temperatures in the range of 280 ⁰ C.

To further explain the invention, an embodiment of the texturing machine according to the invention will be described below with reference to the accompanying drawings.

In Fig. 1, a first embodiment of the texturing machine according to the invention is shown in a cross-sectional view schematically. The texturing machine has two mirror-image juxtaposed machine halves. The left half of the machine is identified by the reference numeral 1 and the right half of the machine by the reference numeral 2. In the further course of the description, the process units and device parts associated with the machine halves are additionally provided with the reference numeral 1 or 2 in order to identify the affiliation with the machine halves.

Each of the machine halves 1 and 2 includes a plurality of processing points to each in each of the processing points to texturize and wind a thread. In the illustrated view in Fig. 1 in each of the machine halves 1 and 2 each of the yarn path of a processing point is shown. The machine halves 1 and 2 have in the longitudinal direction - in FIG. 1, the plane of the drawing is equal to the transverse plane - further processing points to simultaneously texturize and wind several threads parallel to each other. The take-up devices within the machine halves 1 and 2 occupy a width of three processing points, so that in each case three take-up devices are arranged one above the other in a column one above the other. The cross-sectional view shown in Fig. 1 thus represents the yarn path 2 in the machine halves 1 and 2 opposite processing points, the process units required for pulling, guiding, texturing, treating and winding the threads are held on a machine frame 4.1 and 4.2, the Machine frame 4.1 of the machine half 1 holding the process units to a an operation gear 20.1 teilumschließenden threadline and the machine frame 4.2 holds the process units in the machine half 2 to an operating gear 20.2 teilumschließenden threadline.

The process units are described below with reference to the thread run in the processing station of the left half of the machine 1. The arrangement of the process units in the right half of the machine is mirror image identical, so that at the same time the structure of the right half of the machine 2 is explained.

For removing the thread 40 in the processing station of a held in a gate frame 3.1 feed bobbin 5 a deduction delivery 6.1 is provided. The deduction feed unit 6.1 follows in the yarn path a texturing zone with a texturing heater 7.1, a texturing cooler 8.1 and a texturing unit 9.1. This is followed by a draft delivery unit 10.1, a turbulizer 11.1, a supplier 12.1, a heater 13.1, a set-supply 16.1 and a take-up 17.1 connects. The abovementioned process units can be designed and driven as individual units per processing point or as multiple units for a group of processing points. The processing units of the processing station in the machine half 1 can be driven and controlled independently of the processing units of the processing station of the opposite machine half 2. Thus, the threads in the processing points of the left half of the machine 1 can be texturized independently and according to individual specifications. For thread guidance within the processing points further here unspecified yarn guide elements in the form of yarn guide and guide rollers are arranged, so for example, the thread in the transition between the Texturi rierheizer 7.1 and the texturizing 8.1 guided by the guide roller 19.1. The thread guide elements shown in Fig. 1 further will not be further explained at this point.

In order to obtain the most compact possible arrangement of the process units in the machine halves 1 and 2, arranged in a plane of symmetry heaters 13.1 and 13.2 are held together in an insulating housing 14. To avoid mutual interference in the tempering of the threads by the heaters 13.1 and 13.2 a thermal barrier 15 between the heaters 13.1 and 13.2 is provided within the insulating housing 14. The thermal barrier 15 is shown in dashed lines in Fig. 1 in the insulating housing 14. The structure of the insulating housing 14 and the formation of the heaters 13.1 and 13.2 with the thermal barrier 15 will be explained in more detail below.

The insulating housing 14 is held in the machine frames 4.1 and 4.2 between the stacking arranged winding devices 17.1 and 17.2. In this case, the insulating housing 14 preferably also take over supporting functions of the machine frames 4.1 and 4.2, for example, to fix the winding devices 17.1 and 17.2. Overall, this makes it possible to achieve a very compact arrangement in the middle region of the machine halves 1 and 2, without hindering the individual application possibilities and setting options of the heating devices 13.1 and 13.2.

The texturing machine shown in Fig. 1 is suitable for texturing, stretching, shrinking and winding a synthetic thread. The arrangement and design of the processing units within the machine halves 1 and 2 is exemplary in this case. Thus, for example, the as supply units with single drives shown supply plants also replace by group supply plants, in which the threads are supported by a driven delivery shaft.

The heaters held in the plane of symmetry of the texturing machine

13.1 and 13.2 are protected from the environment by the insulating housing 14 to prevent heat loss. 2 and 3, the structure of the heaters 13.1 and 13.2, as arranged in Fig. 1, described in more detail. FIG. 2 shows a schematic view of the insulating housing 14 with enclosed heating devices 13.1 and 13.2, and FIG. 3 shows a schematic cross-sectional view of the insulating housing 14 with the heating devices 13.1 and

13.2 shown. Unless an explicit reference is made to one of the figures, the following description applies to both figures.

The insulating housing 14 is cuboid and formed by rectangular side plates 26 and end plates 36. At the bottom, the side plate 26 and the end plates 36 are closed by a bottom plate 22 and on the top by a cover plate 21. Within the insulating housing 14, the heaters 13.1 and 13.2 are arranged. The heating devices 13.1 and 13.2 are designed as so-called tube heaters, which each have a heated heating tube for heating the filaments. The heating tubes 28. 1 of the heating device 13. 1 protrude out of the insulating housing 14 with a respective inlet end and outlet end. The heating device 13.1 has a plurality of heating tubes 28.1 in order to temper a group of threads simultaneously. In this embodiment, the heater 13.1 is equipped with a total of seven heating tubes 28.1. The heater 13.1 is arranged parallel to one of the side plates 26 of the insulating housing 14 for this purpose.

On the opposite side of the insulating housing, the second heating device 13.2 with identical construction is parallel to the opposite side plate. te 26 held. The heater 13.2 also has a plurality of heating tubes 28.2, which protrude respectively with their inlet ends and outlet ends of the insulating housing 14. The heating tubes 28.1 are hollow-cylindrical with open ends, so that the filaments pass through the heating tubes 28.1 and 28.2 for heating purposes.

Within the insulating housing 14, a heat barrier 15 is formed between the heaters 13.1 and 13.2. In the embodiment shown in FIGS. 2 and 3, the thermal barrier 15 is formed by an air gap 24 extending substantially over the entire length and width of the heating devices 13.1 and 13.2. The air gap is connected via an upper opening 23 in the cover plate 21 and through a lower opening 25 in the bottom plate 22 with the environment. The upper opening 23 and the lower opening 25 are slot-shaped and extend substantially over the entire width of the air gap 24.

As shown in Fig. 3, the heaters 13.1 and 13.2 are each arranged in an insulating chamber 14 formed within the insulating chamber. The heater 19.1 is arranged in the insulating chamber 27.1 and the heater 13.2 in the insulating chamber 27.2. To form the insulating chambers 27.1 and 27.2, two separating plates 37 are provided within the insulating housing 14, which extend parallel to the side plates 26 and form the air gap 24 between them.

The structure of the heaters 13.1 and 13.2 is identical, so that the device of the heater 13.1 is described in detail for explanation. The heating tubes 28.1 penetrate the insulating housing 14 from the cover plate 21 to the bottom plate 22. Within the insulating chamber 27.1 heating means are provided which heat the heating tubes 28.1 from the outside. The heating medium used here is a heat transfer medium, for example a diphyl. To guide the Heat transfer fluid and heating of the heating tube 28.1 is in the insulating chamber 27.1 in the upper part of a distribution chamber 29 arranged in the form of a tube, which is penetrated by the heating tube 28.1. The distribution chamber 29 is coupled via an inlet 34 with a heat carrier circuit.

In the lower part of the insulating chamber 27.1, a collecting chamber 30 is arranged, which is also penetrated by the heating tubes 28.1. the collection chamber 30 is connected via a drain 35 with the heat transfer circuit, not shown here. The upper distribution chamber 29 and the lower collection chamber 30 are interconnected by a plurality of jacket tubes 31, which are arranged substantially coaxially to the heating tube 28.1 and thereby completely enclose them. Thus, each of the heating tubes 28.1 can be uniformly heated by the guided in the jacket tubes 31 heat transfer medium.

The distribution chamber 29, the collection chamber 30 and the jacket tubes 31 are wrapped within the insulating chamber 27.1 with an insulating material 33 in order to avoid possible heat loss to the environment. As insulation material 33, for example, a glass wool can be used.

The heater 13.1 and the heater 13.2 are constructed identically, wherein the heating tube 28.1 and the heating tubes 28.2 by separate heat transfer circuits, which are independently adjustable and adjustable, are heated.

As can be seen from Fig. 1, the insulating housing 14 is held in the plane of symmetry such that the heating tubes 28.1 and 28.2 of the heaters 13.1 and 13.2 are aligned substantially vertically. As a result, the thermal barrier 15 can advantageously be improved in that, due to a natural chimney effect, an air flow forms within the air gap 24, one of the surroundings via the lower opening 25 in the base plate 22 entering air flow ensures that an exchange of air takes place via the upper opening 23 in the cover plate 21 with the environment. As a result, operating conditions can be created in the texturing machine which make it possible to produce and wind a crimped yarn with heat treatment in one of the machine halves and a crimped yarn in the adjacent machine half without heat treatment. Here, the guided through the non-activated heater yarn is slightly heated. Regardless of the design of the thermal barrier, which may for example also be formed by an insulating material, it is therefore essential that, when only one of the heating devices is used, the filaments in the non-activated heating means are heated to a maximum temperature of <80 °. This ensures that no undesired thermal changes to the unheated filaments occur.

In order to avoid undesired heat losses in operating states in which heat treatment of the crimped threads takes place in both machine halves of the texturing machine, a further embodiment of an insulating housing 14 with integrated heating devices 13.1 and 13.2 is shown in FIG. 4, as in the texturing machine, for example 1 would be used. The embodiment shown in FIG. 4 is substantially identical to the embodiment shown in FIGS. 2 and 3, so that only the differences will be explained below and otherwise referred to the above description.

In the embodiment of the insulating housing shown in Fig. 4, the thermal barrier 15 between the heaters 13.1 and 13.2 is also formed by an air gap 24. The air gap 24 is via a lower opening 25 in the bottom plate 22 and through an upper opening 23 in the cover plate 21 with the

Environment connected. On the cover plate 21, a lid 38 is held, which is adjustable via a pivot axis 39 between two positions. In the position shown in Fig. 4, the lid 38 is located with a longitudinal side on the cover plate 21st at. The upper opening 23 formed in the cover plate 21 is closed by the cover 38.

In a deflected position of the lid 38, which is shown in dashed lines in Fig. 4, the lid 38 is guided in a position in which the opening 23 in the cover plate 21 is open and connected to the environment. Thus, the heat exchange processes generated by the chimney effect in the air gap 24 can be adjusted depending on the operating state. In the event that the heaters 13.1 and 13.2 are activated with substantially identical operating settings, the upper opening 23 in the cover plate 21 is closed by the lid 38. Thus, no heat exchange occurs in the thermal barrier 15.

In the event that a tempering of the crimped threads is desired in the texturing only in one of the machine halves, the lid 38 is held in an open position on the insulating housing 14. As a result, the desired heat exchange occurs in the thermal barrier 15.

The embodiment of the lid 38 and the connection to the heater 13.1 or 13.2 via a pivot axis 39 is exemplary. In principle, it is also possible to place the cover 38 as a separate component on the opening 23 of the cover plate 21, so that if necessary, the lid 38 is completely removable.

The type, design and arrangement of the processing units within the texturing machine of FIG. 1 is exemplary. Basically, the invention extends to both semi-automatic and automatic texturing machines. The invention enables flexible use of the texturing machines, in which the machine halves can be used individually to produce different textured threads. Conversions for dismantling or mounting a heating device in one of the machine halves or both nenhälften can advantageously be omitted. Thus, each of the machine halves can be operated with or without activated heating device. The invention is not limited to the fact that the heater is formed by a so-called tube heater. It is also possible to advantageously use contact heaters or non-contact heaters with electrical heating of the thread guide elements. Likewise, the number of simultaneously treated by a heater threads is exemplary. Thus, heating devices for individual treatment of threads can be performed.
