In order to obtain a high integration and closeness of the process units inside the machine frame, the invention provides that a portion of the process units are held in an overlapping manner by at least one frame part of the machine part, said frame part facing the operator passage, the guiding of the thread ensuing between the overlapping process units via a redirecting means.

Description

Texturi ermaschine

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

For texturing synthetic threads, two types of texturing machines differing in the degree of automation are known in the prior art. Thus, in the so-called semi-automatic texturing the bobbin change manually by an operator to perform. An example of a semi-automatic texturing machine is known for example from DE 34 00 767 Al. Here, an operating gear is formed in the texturing machine in order to be able to operate by an operator arranged in the texturing machine process units when threading and to be able to perform the bobbin change during operation.

In contrast, in the so-called automatic texturing machines, the bobbin change is carried out automatically, so that without manual intervention a thread can be continuously textured and wound in a processing station. Such a texturing machine is known for example from DE 197 05 810. In the known automated texturing machine, a so-called Doffgang is formed on the machine parallel to the operation gear, through which the Spulenabtransport takes place. The operation is used here for the operation of the process units in particular for applying the threads before the start of the process.

Regardless of the type of Texturiermaschine are the deducting, guiding,

Treating and winding the threads required process units to a threadline held one behind the other in a machine frame. Here, the largest installation spaces are required for the process units for temperature control of the threads. which leads in many cases to a multi-layered construction of the texturing machine. The integration of such elongated process units therefore usually requires additional auxiliary equipment for operating the processing units.

It is an object of the invention to provide a texturing machine of the generic type, in which the process units can be kept in the most compact possible arrangement within the machine frame.

This object is achieved by a texturing machine with the features of claim 1.

Advantageous developments of the invention are defined by the features and feature combinations of the respective subclaims.

The invention proceeds to thread guide a completely new way, which turns away from the fact that in a yarn path subsequently arranged process units are held one behind the other. By contrast, the invention uses the depth of the machine to overlap the process units on the frame part of the machine frame facing the operating gear, wherein the thread guide takes place between the overlapping processing units by a deflection means. This allows a large number of process units to be integrated in a small space within a machine frame.

The further development of the invention, in which the process unit facing the frame part has a holding device for receiving the overlapping process unit, is particularly advantageous, since in this case one of the process units can be integrated as a load-bearing element in the machine frame. The integration of the process units as load-bearing parts in the machine frame enables completely new rack systems, which only bring about the required stability together with the processing units. This makes it possible to realize very compact, user-friendly and cost-effective texturing machines. In this case, the process unit can preferably be used for stiffening the machine frame, in order to still ensure interchangeability of the process unit.

For the formation of a semi-automatic texturing machine, the further development of the invention is particularly preferred, in which the processing units of the processing station are held in such a way that the process units are within the range of a control system. Thus, the application of the yarn at the beginning of the process and the bobbin change by an operator could be carried out in a simple manner.

Irrespective of the type of texturing machine, the further development of the invention provides for the frame part of the machine frame to be arranged between the operating gear and the gate frame and for which the process unit facing the frame part is formed by a substantially vertically oriented heating device with one heating tube per processing point is the advantage that even very long process units can be integrated within the machine frame at low heights.

The deduction delivery unit assigned to the creel frame can advantageously be attached to the side of the heating device facing the operating passage.

In order to realize as possible a short thread guide between the gate frame and the deduction delivery, the development of the invention is preferably used, in which the heater per processing point has a passage for feeding the thread from a supply spool in the gate frame to the deduction delivery. Such feeds are preferably formed by guide tubes extending from the gate frame to the deduction delivery unit.

The further development of the invention, in which the frame part is arranged on the side of the machine frame opposite the gate frame, and in which the process unit facing the frame part is formed by a set heater oriented essentially vertically, is characterized by the fact that in so-called Heater machines can be minimized the necessary parts to accommodate the process units. In particular, the process frame usually provided for receiving the set heating device and the adjacent winding frame carrying the take-up device can thus be combined to form a single frame part.

For this purpose, it is advantageous to assign a take-up device to the side of the set heating device facing the operating passage. Thus, the set heater on a holding device to facilitate the reception and fixation of the take-up in the machine frame, so that both the set heater and the take-up are held in a common frame part of the machine frame in a confined space next to each other.

On the one hand to obtain sufficient freedom of movement for an operator operating in the operating gear and on the other hand to allow quick access to the process units at the start of the process development of the invention is particularly advantageous, in which arranged on both sides of the operating gear processing units with a distance of <1, 5m to each other are arranged, wherein in the processing point, a cooling device determines the yarn path o- above the operating path. In this case, the formation of the cooling device by an actively coolable cooling tube is particularly preferred, which spans the operating passage substantially in a horizontal position with an inclination angle of 0 to 30 °, to be able to sufficiently cool threads even at low cooling lengths at high process speeds.

The integration of the heating device on the rack frame facing the frame part of the machine frame also has the advantage that holding devices for additional units can be accommodated, by which processing point a second thread is feasible. Thus, the texturing machine can also be used for the production of composite threads.

Further advantages of the invention will be explained below with reference to an embodiment with reference to the accompanying figures.

They show:

texturing

Fig. 4 shows schematically another embodiment of the texturing machine according to the invention

FIG. 1 schematically shows a first exemplary embodiment of a texturing machine in a cross-sectional view. The texturing machine has a machine frame 2, which consists of several frame parts 2.1, 2.2 and 2.3. The frame parts 2.1, 2.2 and 2.3 are arranged relative to each other such that an operating passage 22 is formed therebetween. Immediately next to the machine frame 2 is a gate tergestell 1 arranged, which holds a plurality of feed bobbins 26 for withdrawing a respective thread.

In the longitudinal direction-in FIG. 1 the drawing plane is equal to the transverse plane-the texturing machine has a multiplicity of processing points in order to texturise one thread in each of the processing points. The take-up devices within the texturing machine occupy a width of three processing points, so that in each case three take-up devices are arranged in the form of a tier in a column one above the other in the machine frame 2.

The cross-sectional view shown in Fig. 1 thus represents the yarn path in one of the processing stations, the process units required for pulling, guiding, handling and winding the thread on the frame parts 2.1, 2.2 and 2.3 of the machine frame 2 to a gangway 22 teilumschlie- ing Threadline are arranged.

Below, the process units are described in more detail on the basis of the thread run in one processing point. To pull off the thread in the processing station from a supply reel 26 held in the gate frame 1, a deduction delivery unit 3 is provided. The deduction delivery 3 follows in the yarn path a heater 4, a cooling device 6, a Texturieraggregat 9, a draft delivery unit 10, a turbulizer 11, a set delivery 12 and the winding device 13. The aforementioned process units can here as individual units per processing point or as multiple units for a Group of workplaces trained and driven. To fix the process units in the machine frame 2, the heater 4 is first attached to the disposed between the service corridor 22 and the gate frame 1 frame part 2.1 in a substantially vertical arrangement. The design of the heater 4 will be explained in more detail below. In the lower area, the heater 4 carries a holding device 5, to which the deduction delivery unit 3 is attached. The deduction delivery unit 3 is hereby kept within the working height of an operator. Below the deduction delivery unit 3 and below the inlet of the heater 4, a deflection means 19 is provided to transfer the running of the deduction delivery unit 3 thread in the heater 4. As deflecting means 19, preferably a plurality of deflection rollers are used.

The deduction delivery unit 3 and the heating device 4 are overlapping arranged process units, which are held on the machine frame part 2.1.

In the further yarn path of the heater 4 follows a cooling device 6, which is arranged substantially horizontally aligned on the frame part 2.2 above the operating path 22. The cooling device 6 has per processing point on a cooling tube 8, which is cooled by an internally flowing cooling medium. The position of the cooling tube is determined essentially by an angle of inclination α, which may be formed in the range of 0 to 30 ° relative to the horizontal.

The cooling device 6 are downstream of the texturing unit and the drafting device 10 in the yarn path, which are attached to the frame part 2.3. In the further course follows on the machine frame part 2.3, the swirling device 11 and the set delivery mechanism 12, wherein between the swirling device 11 and the set delivery mechanism 12 a plurality of guide rollers 20 are provided for thread guidance. The set delivery mechanism 12 is arranged below the take-up devices 13, so that the thread runs from below into the take-up device 13. Each of the three superimposed processing stations arranged Aufwickeleinrichtungen comprise a bobbin holder, on which a coil 14 is held and wound, which is driven via a drive roller 15 during the Wickeins. The bobbin change takes place here manually by an operator from the operation gear 22 out. The operating gear 22 is kept as narrow as possible so that all processing units can be operated quickly and safely when threading one after another. The distance between the processing units arranged opposite the operating unit is preferably less than 1.5 m.

For the supply of the threads from the gate frame 1 to the deduction delivery unit 3, a guide tube 21 is provided per thread. The design of the heating device 4 and the arrangement of the guide tubes 21 is apparent in particular from the schematic view of several adjacent processing points shown in Fig. 2. The heating device 4 has a heating tube 7 for each processing point, through which the thread is guided. The heating tube 7 is disposed within a heating tube 28 and is heated by a contained in the heating tube 28 heat transfer medium. The heat transfer medium is in this case supplied and removed by an upper distribution chamber 24 and a lower distribution chamber 25. The heating pipes 28 are in this case with the distribution chambers 24 and 25 in connection. The distribution chambers 24 and 25 and the heating tubes 28 also have here not shown insulating materials. Between the heating tubes 28, a passage 23 is formed per processing point, through which the guide tube 21 assigned to the thread supplied to the processing point is guided. In this case, the guide tube 21 ends in the vicinity of the deduction delivery unit 3 in the processing station. The deduction delivery unit 3 is shown in this embodiment as a wrapping delivery plant with a godet and a bail roll. For this purpose, the galette is driven by an electric motor.

For the first application of the threads in the processing points of the heater 4 is associated with a pneumatic application device, through which the threads are pneumatically inserted into the heating tube 7. Such pneumatic guide systems are generally known and therefore not described in detail at this point. The texturing machine shown in Fig. 1 is suitable for texturing a synthetic thread and winding it into a bobbin. In the event that a shrinkage treatment on the thread is required prior to winding, the texturing machine shown in FIG. 1 can be supplemented without significant changes by a set heater 18 and a pre-set delivery mechanism 17. For this purpose, the set heating device 18 and the pre-set delivery mechanism 17 is shown in dashed lines in the yarn path in Fig. 1. These process units are held here in the frame part 2.3.

The exemplary embodiment illustrated in FIG. 1 for the arrangement of the processing units within the machine frame of a texturing machine is exemplary. In principle, other process units such as the set heater are suitable to be integrated as a supporting element in the machine frame for fixing other process units. Likewise, the training of the delivery works as wrapping delivery plants with single drive is exemplary. In semi-automatic texturing machines, it is preferred to use group supplying plants in which the threads are conveyed by a driven delivery shaft.

In Fig. 3, another embodiment of the texturing machine according to the invention is shown. The embodiment is substantially identical to the aforementioned embodiment, so that reference is made to the above description and only the differences will be explained at this point. For this purpose, the components with the same functions are identified by identical reference symbols.

In the embodiment shown in FIG. 3, a composite thread made of a textured thread 27 and a non-textured thread 29 is produced per processing point. For this purpose, the heating device 4 has an upper holding device 5.1 and a lower holding device 5.2. At the upper holding device 5.1 is a first deduction delivery 3.1 and at the lower holding device 5.2 a second deduction delivery 3.2 arranged. The lower take-off delivery plant 3.2 in this case leads to the thread 27 to be textured, which is subsequently guided by the heating device 4, the cooling device 6 to the texturing unit 9. The trigger delivery 3.1, however, draws a vacant thread that is not textured, for example, an elastane thread. The elastane yarn 29 is fed directly to the swirling device 11 by means of a plurality of deflecting rollers 20 after the take-off delivery unit 3.1. In the turbulizer 11, the elastane yarn 29 is combined with the textured yarn 27 to form a composite yarn and then fed via the pre-S et- delivery 17 in the set heater 18. After the shrinkage treatment, the composite thread is fed via the set delivery mechanism 12 to the take-up device and wound up into a bobbin. In the embodiment shown in Fig. 3, the attached to the heater 4 second deduction delivery as an additional unit is exemplary. In principle, further or other additional units such as presentation points or draw pins can be positioned on the heating device.

FIG. 4 shows a further exemplary embodiment of the texturing machine according to the invention. This is a so-called two-heater machine, in which a first heating device 4 in the false twist zone and a second heating device 18 are provided for shrinking treatment.

The process units for stripping, guiding, treating and winding a thread within a processing station are essentially identical to the embodiment of the texturing machine according to FIG. 1. In that regard, reference is made to the above description and only the differences are mentioned here.

The machine frame 2 is formed by the frame parts 2.1, 2.2 and 2.3, which include an operating passage 22 between them. In addition to the machine frame 2, a gate frame 1 with a plurality of feed bobbins 26 is arranged. The gate frame 1 facing frame part 2.1 carries a deduction delivery 3 and a Heating device 4. The deduction delivery unit 3 is arranged in this case in front of the inlet of the heater 4. Thus, the heater 4 could also be formed by a high-temperature heater having a closed by a lid slot-shaped Heiznut.

A substantially extending over the operating passage 22 cooling device 6 is supported on the frame part 2.2 from. On the gate frame 1 towards the opposite side of the machine frame 2, the frame part 2.3 is provided for receiving the process units. In the upper region of the frame part 2.3, the texturing unit 9 and the stretch delivery units 10 and pre-set delivery mechanism 17 are arranged. Between the delivery mechanisms 10 and 17, a turbulizer 11 is provided. In the lower region of the frame part 2.3, a set heating device 18 is integrated as a supporting part in the frame part 2.3. On the side facing the operating passage 22 of the set heating device 18, a holding device 5 is provided for fixing the take-up device 13, which is likewise held in the frame part 2.3. Below the set heating device 18 and the winding device 13, a deflection roller 20 and a set-delivery mechanism 12 is provided to deflect a thread 27 in a U-shape.

The process units, which are held around the operation gear 22 on the frame parts 2.1, 2.2 and 2.3, can all be operated by an operator from the operation gear 22. Thus, both the thread application and the bobbin change can be performed in the processing station by an operator. Usually, such texturing machines have a plurality of processing points next to one another. As a result of the compact arrangement of the process units, it is thus possible to operate a large number of process units and processing stations by an operator. The gate frame 1 opposite side of the machine frame 2 in this case preferably forms a plane of symmetry to connect a second texturing machine mirror image. The type, the design and the arrangement of the process units in the embodiment shown in Fig. 1 to 4 is exemplary. In principle, the invention extends to both semi-automatic and automatic texturing machines. What is essential here is the immediate overlapping arrangement of the processing units on a frame part of the machine frame, so that a straight thread run which is customary in the prior art is replaced by a U- or V-shaped thread run between the processing units. Thus, a high density of process units is realized within a machine frame, so that even complex machine structures can be installed in a single machine level.
