Description

The invention relates to a texturing machine with a plurality of processing stations according to the preamble of claim 1.

In the production of synthetic threads, the plain yarns produced in a melt spinning process are crimped, in particular for textile applications in a subsequent process. This process is known in the art by the term texturing, wherein the synthetic threads are stretched simultaneously in the texturing process. Such texturing processes on a multiplicity of threads are carried out with the aid of texturing machines which have a corresponding multiplicity of processing stations. In each processing point at least one thread is treated by several processing units. The process units such as texturing units, delivery mechanisms, heaters, cooling devices and Aufspulaggregate are distributed to the processing points and arranged in a multi-part machine frame, so that adjusts a predetermined yarn path in the processing stations. In order to ensure in particular the operability of the processing points, different concepts for the arrangement of the individual machine frame parts to each other are known in the prior art.

In a first variant, the processing points are operated within the machine from different levels of operation. Such a texturing machine is for example from the DE 23 50 558 known. In the known texturing, the process units are at a middle Process rack held, which extends over two floors. In an upper operating floor, the process rack is assigned a rack frame, on which the supply bobbins required for the processing stations are held. In the lower operating floor of the process frame, a winding frame is assigned, on which the Aufspulaggregate are held. Both between the winding frame and the process frame at the lower operating level and between the gate frame and the process frame in the upper operating level two operating paths are formed in each case.

Such an arrangement of the machine frame parts makes it particularly difficult to operate the processing points at a process start or after a thread break. In order to create a thread in one of the processing stations, the operator must operate the processing units distributed over two floors. This mode of operation can only be achieved with a greater use of operating personnel or additional auxiliary equipment.

A second variant of the arrangement of the machine frame parts, which has prevailed in practice and can be considered as standard, is for example from EP 0 641 877 B1 known. In this texturing machine, the machine frame parts are arranged side by side in a plane, wherein a part of the process units are held by a superstructure in an upper operating floor. For example, the winding frame and the process frame are arranged opposite one another and form an operating passage between them. Above the winding frame and the process rack, a superstructure is provided on which the heating device and the cooling device are held. In this case, the process units are assigned several auxiliary devices to perform an operation in the upper operating level can. Moreover, such texturing machines have a so-called Doffgang, which extends along the winding frame and allows the clearing and removal of the wound full bobbins. Likewise, the gate frame is assigned a Doffgang to allow the delivery and the placement of new supply bobbins. In that regard, such texturing on a relatively large footprint.

In the search for economical and compact machine arrangements, other concepts of a texturing machine can also be found. For example, from the DE 39 31 878 A1 a texturing machine is known in which a Doffgang is formed between two winding frames. The winding frames are connected to each other via a cross member, which essentially serves to accommodate the process units. In that regard, can be used by additional climbing means of Doffgang also to operate the process units. Here, both the removal of the bobbin and the operation must be performed out of a common Doffgang, which often leads to disabilities and collisions in the large number of processing points along a machine side.

From the EP 2 145 848 A1 a false twist texturing machine is known for texturing a plurality of multifilament yarns, comprising a plurality of delivery mechanisms of a heating device, a cooling device, a false twist device and a winding device for drawing off, drawing, texturing and winding at least one of the threads.

From the DE 23 50 558 A1 is a draw-texturing machine for threads of synthetic fibers known.

From the DE 101 23 042 A1 For example, a false twist texturing machine is known for draw texturing thermoplastic threads having a plurality of processing locations.

From the DE 74 19 925 U is a formed as a high gate feed bobbin gate for draw texturing known, with an elevated mounted on the gate catwalk for connecting to an adjacent gate.

It is an object of the invention to provide a texturing machine of the generic type, in which the operation of the machine and the bobbin transport to the machine are as efficient as possible executable.

Another object of the invention is to realize a compact as possible space-saving arrangement of the machine frame parts.

This object is achieved in that the process frame is arranged with the process units on an upper operating floor along an operating gear and that the winding frame is arranged with the Aufspulaggregaten on the lower operating floor along a Doffganges.

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

The invention is characterized in that the process units can be operated together from one operating gear. For an operator, all process units that are particularly important for the texturing process are arranged in the upper operating level and can be operated for all processing points from the upper operating level. In contrast, the Spulenabtransport takes place from the Doffgang in the lower operating floor. In addition, the space requirement of the texturing machine is limited at a ground level on the winding frame and the Doffgang. Thus, such texturing machines can be combined to a large majority within a machine shop.

Since the transport path for the feed bobbins and the transport path for the wound coils require different distances, the development of the invention is particularly advantageous, in which the gate frame with the feed bobbins on an upper floor above the process rack is arranged. This allows the delivery of the bobbins and the supply of the gate racks regardless of the operation of the processing points and the removal of the coils run.

Alternatively, however, it is also possible to enable the transport of the supply bobbin and the wound bobbin from one floor. For this purpose, it is proposed to arrange the gate frame with the feed bobbins together with the winding frame on the lower operating level.

In the case of texturing machines, it is customary for the processing stations to be arranged next to one another with the closest possible pitch and to form a machine longitudinal side with up to more than 100 processing points. In order to be able to comply with such machine divisions across all processing stations, it is further provided that in each case a staircase is formed at the front ends of the machine frame, which connects the upper service aisle with the lower service floor. Thus, there is the possibility that during operation an operator lingers in the upper operating level and ensures the operation of all processing points.

Furthermore, it is customary to produce texturing machines with a so-called A-side and a B-side in order to be able to offer twice the number of processing points. For this purpose, the development of the invention is used, in which the machine frame has a second mirror-symmetrical machine half with a second process frame, with a second winding frame and with a second frame frame.

The process racks are arranged mirror-symmetrically on the operating floor facing each other. The winding frames are also mirror-symmetrically opposed on the lower operating level. This arrangement of the process units makes it possible to carry out all operating processes for the process start or in the event of a yarn break at the processing points of both machine halves from one operating cycle.

In order to obtain an advantageous for the operation of the process units low construction, the development of the invention is particularly advantageous in which a plurality of heaters, which are provided for heating the threads are arranged on the process frame with a slope in the machine longitudinal direction together in a plane , By having a slope juxtaposed heaters can be realized even in compact arrangements with low height relatively long heating distances for temperature control of the threads in the texturing. In addition, the heaters can be kept in close proximity, so that the heat losses can be minimized.

Depending on the design and inclination of the plane in which the inclined heaters are held, integration is possible both on the process rack and on a crossbeam connecting adjacent process racks.

In order to obtain as few yarn rubbings in the processing points, in particular in the texturing zones of the processing points, is in accordance with According to an advantageous development of the invention, the heaters can be allocated to a plurality of cooling devices on an outlet side, wherein the cooling devices and the heaters in the plane each form a straight yarn path per machining point.

In the event that a thread material is textured, which requires an aftertreatment, the development of the invention is particularly suitable, in which the process frame or the process racks carry a plurality of Nachheizeinrichtungen for heating the threads and in which the Nachheizeinrichtungen common with a slope in the machine direction arranged in a plane. In that regard, the advantages in the arrangement of the heaters can also be used in the arrangement of the afterheating. By choosing the size of the slope of the Nachheizeinrichtungen also the positions of the Aufspulaggregate can match the yarn path in the texturing zone.

The afterheating devices are preferably held in a lower region of the process racks. Thus, the threading of the threads into the afterheating devices can advantageously be carried out of the operating aisle.

The delivery mechanisms provided in the processing stations are also held so that they can be operated out of the operating gear. As delivery plants hereby single driven godets or shaft systems with pressure rollers can be used.

The texturing machine according to the invention can basically be used independently of the respective degree of automation of the winding units. Thus, the texturing machine according to the invention can be equipped with Aufspulaggregaten, in which the coils are changed automatically or manually.

For further explanation of the invention, some embodiments of the invention will be described in more detail with reference to the accompanying figures.

In the Fig. 1 to 3 a first embodiment of the texturing machine according to the invention for texturing a plurality of threads is shown in different views. In Fig. 1 is the embodiment in a cross-sectional view and in the Fig. 2 and 3 each in a section a side view and a top view of the process frame shown. Unless expressly made to any of the figures, the following description applies to all figures.

The embodiment of the texturing machine has a multiplicity of processing points, which are arranged next to one another on a multi-part machine frame 1 along a machine longitudinal side. Thus, for example, more than 100 processing stations can be arranged next to one another in the machine frame 1.

As from the illustration in Fig. 1 shows, the machine frame 1 from a winding frame 3, a process frame 2 and a gate frame 5 is formed. The winding frame 3 is located on a lower operating floor 30.1 and is placed directly on the floor of a machine hall. The process frame 2 is supported above on the winding frame 3 and forms an upper operating floor 30.2. The gate frame 5 is arranged on an upper floor 31 directly above the process rack 2.

At the gate frame 5 a plurality of supply spools 16 and a plurality of reserve spools 17 are held, wherein in each case a supply spool 16 and a reserve spool 17 is assigned to one of the processing points. The gate racks 5 usually have the feed bobbins of a group of processing stations. In that regard, several frame racks 5 are usually kept side by side along the machine longitudinal side.

The gate frame 5 is assigned a transport passage 32 on the upper floor 31. About the transport passage 32, the delivery and the subsequent placement of the gate 5 is performed by an operator.

Within the processing stations, the threads are each deducted from the supply bobbins 16 via a bottom opening 33 in the upper floor 31 and fed to the process units on the process rack 2 located thereunder. Since the construction of the processing stations is identical, the process units are subsequently identified by means of a yarn path within one of the processing stations with reference to the illustration in FIG Fig. 1 described in more detail.

In the Fig. 1 shown processing point has on a cross member 4 of the process frame 2, a first delivery mechanism 8, which subtracts a thread 18 from a supply spool 16. The first delivery mechanism 8 forms with a downstream second delivery mechanism 25 a so-called texturing zone, in which the thread 18 is stretched and textured. The second delivery mechanism 25 is held in the middle region of the process frame 2 for this purpose. Within the texturing zone formed by the delivery mechanisms 8 and 25, a heating device 9, a cooling device 10 and a texturing unit 11 are arranged one after the other in the yarn running direction. The texturing unit 11 is arranged directly above the second delivery mechanism 25 on the process rack 2.

To maintain a maximum operating height and to realize long texturing zones, the heating device 9 and the cooling device 10 are inclined to the process frame 2 in the machine longitudinal direction and the cross member 4 held. To explain the arrangement of the heaters 9 and the cooling devices 10 on the process rack 2 is in addition to the Fig. 2 and 3 Referenced. In Fig. 2 a section of the side view of the process frame 2 is shown. The Fig. 3 shows a plan view of the process frame 2.

In the Fig. 2 and 3 the first two processing points are indicated by the reference numerals 24.1 and 24.2. Since the structure of the processing points is identical, the subsequent processing points are not further marked.

As from the illustrations in Fig. 2 and 3 shows the heater 9 and the cooling device 10 form a common thread running plane, wherein the thread between the first delivery mechanism 8 and the texturing unit 11 associated guide roller 13 is guided in a straight run. Depending on the angle of inclination of the heating device 9 and the cooling device 10, an offset in the processing point 24.1 between the first delivery mechanism 8 and the second delivery mechanism 25 is established. The delivery mechanisms 8 and 25 are arranged in different cross-sectional planes of the process frame 2.

As from the illustration in Fig. 1 As can be seen, in the further course of the thread 18 is guided to a swirling unit 15 and then passed between a third delivery mechanism 26 and a fourth delivery 27 through a post-heating device 14. The afterheating device 14 forms an aftertreatment zone, at low yarn tension, the between the delivery mechanisms 26 and 27 is adjustable to perform a relaxation treatment on the thread 18.

The afterheating device 14 and the delivery mechanism 26 are optional only in the case of a post-treatment of the thread. In the event that the thread material does not have to be aftertreated, the processing points are carried out without reheating and without third delivery.

As from the illustration in Fig. 2 shows, the after-heater 14 is also held with an inclination in the machine longitudinal direction of the process frame 2. The after-heater 14 is preferably aligned at the same inclination angle to the upper heater 9. The inclination angle for aligning the heater 9 and the after-heater 14 is usually in a range of 30 ° to max. 60 °. In principle, however, different angles of inclination for the heating device 9 and the afterheating device 14 can be selected. Thus, depending on the design of the heating device, the afterheating device 14 can also be arranged with an inclination angle in the range from 0 to 45 °.

Parallel to the process rack 2, an operating gear 6 is formed in the upper service floor 30.2. The operation 6 extends to a platform 22 parallel to the process frame 2. At the front ends of the machine frame 1, a stairway 29 is arranged in each case, which connects the operation gear 6 with the lower operating floor 30.1. In the Fig. 1 and the Fig. 3 the staircase 29 is shown at the ends of the process rack 2.

As from the illustration in Fig. 1 As can be seen, the thread 18 is guided by the delivery mechanism 27 to a winding unit 12. The winding unit 12 is arranged on the winding frame 3 arranged below the process frame 2. The winding frame 3 carries several Aufspulaggregate 12 floor-level above the other. Since the Aufspulaggregate 12 produce a coil width that is greater than a pitch between the processing stations, the Aufspulaggregate several processing points are arranged in a stack on the winding frame 2 one above the other. In this embodiment, a total of three Aufspulaggregate 12 are held one above the other on the winding frame 3. In principle, several Aufspulaggregate can be kept one above the other on the winding frame 3.

The winding units 12 are formed in this embodiment as a semi-automatic winding units 28, in which the coils 19 must be changed manually after completion of the winding. For this purpose, a Doffgang 7 is provided parallel to the winding frame 3 along the outer machine longitudinal side. The Doffgang 7 serves an operator to perform the bobbin change in the Aufspulaggregaten 12 and remove the full bobbins.

As from the illustration in Fig. 1 shows, all operations for the first application of a thread or thread break in the process units by an operator from the aisle 6 run out. Thus, the processing points in the machine can be monitored and operated from the aisle 6 in the second operating floor 30.2.

The deliveries and equipment of the gate frame 5 and the manual Spulwechsel and Spulenabtransport can be carried out independently of this. Thus, the texturing machine according to the invention enables an optimal material flow. In addition, the space required to set up the machine is reduced to a minimum.

For conveying and drawing, the delivery plants provided in the processing stations are partly designed as so-called clamping delivery plants or as looping delivery plants. In the case of the terminal delivery systems, the conveyance is transmitted by clamping the thread. In the Umschlingungslieferwerken the necessary conveying forces are caused by a multiple looping of the thread. It has been found that, in particular, the delivery mechanisms upstream of the winding units are preferably designed as clamping delivery units. Thus, the fourth delivery 27 is shown in the processing station as Klemmlieferwerk. The delivery plants associated with the texturing zone are designed as wrapping delivery units which are formed, for example, from a driven galette and an associated overflow roller. In the embodiment, the Lieferweke 8, 25 and 26 are designed as Umschlingungslieferwerke.

It should be expressly mentioned at this point that the arrangement and the design of the thread guide elements and processing units of the processing points in the embodiment shown after Fig. 1 to 3 are exemplary. Thus, the delivery plants can be varied in any combination. Likewise, thread guides without deflection, in particular between the cooling device and the texturing unit executable.

In practice, such texturing machines are preferably formed as a double machine from two mirror-symmetrical machine halves. Such an embodiment of the texturing machine according to the invention is in Fig. 4 shown. At the in Fig. 4 illustrated embodiment, the machine frame is formed of two mutually mirror-symmetrically arranged machine halves, each having a plurality of processing points. The Fig. 4 shows the embodiment of the texturing machine schematically in a cross-sectional view.

Each of the machine halves 1.1 and 1.2 each have a winding frame 3.1 and 3.2, a process frame 2.1 and 2.2 and a gate frame 5.1 and 5.2. The process frames 2.1 and 2.2 are arranged on a platform 22, which is supported on the winding frames 3.1 and 3.2. The process frames 2.1 and 2.2, whose process units are arranged mirror-symmetrically opposite, include an access passage 6 between them. The operation gear 6 extends over the entire length of the process frame, wherein at the front ends of the process frame, a staircase 29 is provided to connect the operation gear 6 with the lower operating floor 30.1. The process units held in the upper operating level 30.2 can be operated together from the operating gear 6 on both process racks 2.1 and 2.2. The arranged on the process racks 2.1 and 2.2 process units are identical to the aforementioned embodiment according to Fig. 1 to 3 , so that no further description is given to the structure of the processing stations at this point. The process frame 2.1 thus maintains in the thread running direction a first delivery mechanism 8.1, a heating device 9.1, a cooling device 10.1 and a second delivery system 25.1. These process aggregates form the so-called texturing zone the relevant processing station. In the further threadline follows a Verwirbelungsaggregat 15.1, a third delivery 26.1, a Nachheizeinrichtung 14.1 and a fourth delivery 27.1.

The same number and design of the process units is held on the mirror-symmetrically opposed process rack 2.2. The process rack 2.2 thus carries a first delivery mechanism 8.2, a heating device 9.2, a cooling device 10.2, a texturing unit 11.2, a second delivery mechanism 25.2, a fluidization unit 15.2, a third delivery mechanism 26.2, an afterheating device 14.2 and a fourth delivery mechanism 27.2. The delivery mechanisms 8.1 and 8.2 and the heaters 9.1 and 9.2 are arranged in this embodiment on a cross member 4, which connects the process frames 2.1 and 2.2. The delivery 8.1 and 8.2, however, are arranged in a machine height that can perform an operator from the aisle 6 out without the aid of other tools a Fadenanlegen.

Below the process frames 2.1 and 2.2, the winding frames 3.1 and 3.2 are arranged, which also face each other mirror-symmetrically and each hold a plurality of Aufspulaggregate 12.1 and 12.2 one above the other. The winding frames 3.1 and 3.2 are assigned to the outer longitudinal sides of the machine each separate Doffgänge 7.1 and 7.2. The winding units 12.1 and 12.2 are executed in this embodiment, identical to the aforementioned embodiment, so that the Doffgänge 7.1 and 7.2 are used by an operator for manual Spulwechsel and removal of the full bobbins.

At the in Fig. 4 illustrated embodiment, the gate racks 5.1 and 5.2 are also arranged on the lower operating floor 30.1. The gate frames 5.1 and 5.2 are respectively compared to the winding frames 3.1 and 3.2 and include between them the Doffgänge 7.1 and 7.2. The Doffgänge 7.1 and 7.2 can hereby be used simultaneously for the delivery of the feed bobbins 16.1 and 16.2 and for equipping the gates 5.1 and 5.2.

In the Fig. 5 is another possible embodiment of a twin machine with two mirror-symmetrical machine halves 1.1 and 2.2 shown. This in Fig. 5 illustrated embodiment is in construction and function of the processing stations substantially identical to the aforementioned embodiments, so that only the differences will be explained below.

At the in Fig. 5 illustrated embodiment, the winding frames 3.1 and 3.2 and the process frames 2.1 and 2.2 are also stacked one above the other, the operation of the process units on the process racks 2.1 and 2.2 from the trained in the upper operating floor 30.1 6 operating gear.

The Aufspulaggregate 12.1 and 12.2 held in the winding frames 3.1 and 3.2 are identically constructed and executed here by way of example as automatic Aufspulaggregate. Each of the winding units 12.1 and 12.2 has in each case a winding station 28.1 or 28.2, a bobbin tray 20.1 or 20.2 and a sleeve magazine 21.1 and 21.2. The provided for an automatic Spulwechsel auxiliary equipment are not shown here.

Such automatic Aufspulaggregate are well known in the art and, for example in the US Pat. No. 6,189,826 B1 described. In that regard, no further explanation is given at this point and taken to the cited reference.

The full bobbins 19.1 and 19.2 produced in the winding units 12.1 and 12.2 are preferably taken off the machine longitudinal sides of the machine halves 1.1 and 1.2 by automated auxiliary equipment such as doffer and discharged via the Doffgänge 7.1 and 7.2. In that regard, in the lower operating floor 30.1 a fully automated operation of the texturing machine executable. The manual operator required is required only for threading the threads in the process units, which is done from the operation gear 6 in the upper operating floor 30.2.

For this purpose, the gate racks 5.1 and 5.2 for receiving the supply bobbins 16.1 and 16.2 and the reserve coils 17.1 and 17.2 are arranged on an upper floor 31. The delivery and loading of the supply bobbins takes place from the formed on both sides of the gate transport passages 32.1 and 32.2. In that regard, the arrangement of the machine frame parts 5.1 and 5.2 identical to the embodiment according to Fig. 1 ,

In principle, however, it should be mentioned at this point that the heating devices shown in the exemplary embodiments and the afterheating devices could also be arranged on the process racks without an inclined position with inclination in the machine longitudinal direction. Essential here, however, is that the operation of all process units centrally from the process rack or the process racks associated operating gear is possible.
