Abstract

A spinning, drawing and texturing machine for the production of curled threads includes a spinning unit and multiple machine modules associated with the spinning unit. Each of the machine modules has multiple processing assemblies for drawing and curling one of the threads, and a spooling unit for winding the thread. The machine modules positioned next to one another form a longitudinal side of the machine. The processing assemblies and the spooling unit are arranged among each other at one of the machine modules such that a narrow machine partition (T) in a range of <800 mm occurs on the longitudinal side of the machine. The spinning unit has one or more spinnerets and one spinning duct within the machine partition (T) per machine module. The spinnerets are held in rows parallel to the longitudinal side of the machine.

Description

Spin-draw-texturing

The invention relates to a spinning-stretch texturing machine for producing crimped threads according to the preamble of claim 1.

Such a spin-draw texturing machine is known, for example, from EP 0 718 424 A1.

In the known spin-stretch texturing machine, the processing units arranged underneath a spinning device for drawing and curling the threads and the winding units are each combined to form individual machine modules. Within the machine modules, in particular, the process units are arranged next to one another, so that a substantially horizontally oriented thread guide on the machine module predominates. Thus, depending on the treatment steps very wide machine modules are needed, which lead to a corresponding large machine pitch. Such large machine partitions, however, in principle have the disadvantage, in particular in the case of single-thread process control, that the spinnerets required for melt spinning likewise have to be held at greater distances from one another within a heated spinneret. However, such spinning devices require a greater energy consumption in order to make continuous heating of the melt-carrying components over the entire machine length. This can not meet today's requirements for high space utilization and low energy consumption.

In order to obtain a high space utilization in the production of a plurality of threads, also such spin-stretch texturing machines are known, in which the parallel juxtaposed threads are passed together over the arranged below a spinning device processing units, to be subsequently wound together in parallel next to each other on a winding spindle to a coil. Such a spin-stretch texturing machine is known for example from the document EP 103 52 38 Al. In systems of this type, several threads are guided, treated and wound up as a thread group per spinning position. In the event that travels in the treatment or during winding one of the threads of the yarn group, the adjacent threads are automatically interrupted in their litigation, so that the entire spinning position is interrupted.

By contrast, the spinning-stretching-texturing machine known from EP 1 300 496 A1 already has the advantage that the threads are wound into bobbins within the spinning position in individual winding stations. However, the process units arranged between the take-up device and the spinning device are provided for guiding a plurality of threads, so that an individual guidance of the threads within the spinning position is not possible.

It is therefore an object of the invention to provide a spin-stretch texturing machine of the generic type, in which even the thread yarn guide the largest possible number of threads in a confined space can be produced flexibly.

Another object of the invention is to provide a spin-stretch texturing machine of the type mentioned, with which an automated production of crimped threads is possible.

This object is achieved by a spin-stretch texturing machine in that the processing units and the winding unit are arranged with each other on the machine modules, which adjusts a small machine pitch in the range of <800 mm on the machine longitudinal side, and that the spinning device per machine module Having one or more spinnerets and a spinning shaft within the machine pitch, wherein the spinneret sen are held in a row-like arrangement parallel to the machine longitudinal side.

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

The invention is detached from the usual in the melt spinning of a variety of threads plant concept, in which a plurality of threads are produced in parallel simultaneously in a spinning position. The spinning stretch texturing machine according to the invention continues the division effected by the machine modules as far as into the spinning device, so that only one thread is produced per spinning position. Within the spinning position, the thread can be formed both from a melt-spun filament bundle or else from a plurality of individual filament bundles, for example in the production of composite threads. The per unit of thread from the winding unit up to the spinneret division of the machine has the particular advantage that significantly less thread waste in the production of a variety of threads with a variety of spinning positions. Thus, it is achieved by the machine division in the spinning device, that fail in a thread break in the spinning position, the so-called sympathy breaks. Only the thread produced in the spinning position is affected, the adjacent threads in adjacent spinning positions remain unaffected. This results in a higher availability of the entire system, since only one thread is affected, for example, during maintenance or cleaning. In addition, no long-protruding process units are required, in particular, during drawing, texturing and winding.

Since the narrow machine division leads to a narrow and high design of the machine, the development of the invention is preferably carried out, in which on the machine longitudinal side an increased operation gear is formed immediately in front of the machine modules, which extends substantially over the entire length of the machine longitudinal side. Thus, all can be side by side operate trained positions out of an operating passage out by an operator.

In a fully automatic package handling, in particular, the development of the invention is provided, in which the operation gear is formed in a plane above the winding units and in which the winding units a Doffereinrichtung is assigned for removal and removal of the coils. Thus, the fully automatic bobbin change and bobbin transport can be carried out in a lower level, in which no access by an operator takes place. In that regard, this high security requirements are met, so that in a semi-automatic machine, the operator operates exclusively from an operating gear out, which is guided above the Doffereinrichtung.

In order to achieve a high degree of flexibility when removing and changing the bobbins in the winding units, according to a preferred development of the spin-stretch texturing machine it is provided to drive and control the winding units of the machine modules independently of each other, each winding unit only winding one thread into one bobbin winds.

In order to enable a continuous thread guide without interruption, the winding units are each carried out with two drivable winding spindles, which are usually held on a rotatable support and thus can be performed alternately in an operating range and a change range.

In these cases, in particular Doffereinrichtungen have been found to be particularly suitable, in which each winding unit is associated with a stationary Spulwechselvorrichtung, which cooperates with a Spulentransporteinrichtung. However, it should be expressly mentioned at this point that other doffing systems with mobile doffers could be used in order to be able to remove the bobbins from the winding units.

To be able to carry out required operating and maintenance work independently of adjacent machine modules, the development of the invention is particularly advantageous, in which the process units of the machine modules are independently drivable and controllable. This allows the production of the threads individually controlled and regulated.

In that regard, the training has proven particularly useful in which per machine module an E-unit for receiving the process units and the winding unit associated drive and control electronics is formed. This results in a very flexible construction of the entire spinning-stretching texturing machine, in which the individual positions for the production of the threads are interchangeable.

In this case, in particular the formation of the spin-stretch texturing machine according to the invention has been found to be particularly easy to use, in which the E-units each have a remotely controllable control unit and that the control units are controlled separately via a mobile control unit. Thus, the process units and the winding unit of a machine module can be operated by an operator from a greater distance. This allows adjustment adjustments of individual process parameters or individual monitoring and control functions to be carried out. In addition, actual data of the position can be displayed and documented.

In order to obtain the most user-friendly arrangement of the processing units, the machine modules each have a frame wall, on which the processing units and the winding unit are held one below the other. This also allows a separation between the thread-guiding components and the Make drives and electronic components in the way that the drives and control are formed on a rear side of the frame wall and the components required to guide the thread are held on a front side of the order wall.

The development of the spin-stretch texturing machine according to the invention, in which the machine modules is associated with a suction device, which suction for each machine module in each case has a suction nozzle upstream in the process unit, is particularly suitable for automation of the entire manufacturing process. Thus, in the case of a winder formation within the processing units, an automated separation of the thread can be carried out, which is then removed continuously via the suction device to a waste container. This is a shutdown of the spinning position is not required. The spinnerets remain in operation, so that after the removal of the winder the production process can be continued very quickly.

In order to automate the spin-draw-texturing machine according to the invention, it is proposed to provide a robot which is movably arranged on the machine longitudinal side and which robot with a movable robot arm carries out the attachment of one or more threads at the beginning of the process and / or after interrupting the process. For a fully automatic operation of the spin-stretch texturing machine is possible.

In order to be able to operate the machine modules formed within a machine longitudinal side, the robot is held on a movable carrier, which carrier can be guided in a vertical plane parallel to the machine longitudinal side. The carrier is equipped with drives, which allows both a vertical and a horizontal movement in a plane, so that the robot receives additional degrees of freedom next to the robotic arm usually formed with multiple axes. In this case, all components used for the thread guidance, treatment, crimping and guidance can be used as process units. Thus, the process unit for drawing the thread is preferably formed by at least two driven godets.

In order to perform as many functions as possible with a few processing units, the first godet is preferably used to pull the thread from the spinning device.

The spin-draw texturing machine according to the invention is particularly suitable for producing multicolored carpet yarns, wherein the crimped yarn is formed from a plurality of monofilaments. In principle, however, individual threads can also be spun, stretched, curled and wound up into a spool within one position.

The invention will be explained in more detail below with reference to some embodiments of the spinning stretch texturing machine according to the invention with reference to the attached figures.

They show:

Fig. 3 and

Fig. 4 shows schematically views of another embodiment of the spin-stretch texturing machine according to the invention In Fig. 1 and Fig. 2 shows a first exemplary embodiment of the spin-stretch texturing machine according to the invention is shown. In Fig. 1 is a front view schematically and in Fig. 2 is a side view of the spin-stretch texturing illustrated schematically. Unless an explicit reference is made to one of the figures, the following description applies to both figures.

The spin-stretch texturing machine is formed in this embodiment by a spinning device 1 and a plurality of arranged below the spinning device 1 machine modules, in this embodiment, three adjacent machine modules 5.1, 5.2 and 5.3 are shown by way of example. The machine modules 5.1, 5.2 and 5.3 include a plurality of processing units 8 for drawing and curling a thread and a winding unit 9 for winding the thread.

The spinning device 1 is divided into several spinning positions 1.1, 1.2 and 1.3, wherein each spinning position is associated with one of the machine modules. Thus, the spinning position 1.1 and the machine module 5.1 form a unit to produce a melt-spun yarn. The spinning position 1.2 and the machine module 5.2 and the spinning position 1.3 and the machine module 5.3 also each form a unit for producing a thread. In that regard, the spin-stretch texturing machine illustrated in Figures 1 and 2 is suitable for making three threads in parallel. In order to obtain the most compact spinning device with correspondingly low energy consumption for temperature control of the melt-carrying components, and on the other hand to obtain a high space utilization when installing such spin-stretch texturing machines, the process units 8 and the winding units 9 within the machine modules 5.1, 5.2 and 5.3 arranged one below the other so that adjusts a very small machine pitch in the range of <800 mm on the long side. The machine division, which is entered by the reference symbol T in FIG. 1, determines the formation of the spinning positions 1.1, 1.2 and 1.3, so that the space required for the production of a thread is essentially defined by the machine parting. Dependent on Whether a composite thread or a single thread is produced in the spinning position as a thread, the machine modules 5.1, 5.2 and 5.3 and the spinning positions 1.1, 1.2 and 1.3 can also be arranged in ranges of <600 mm.

In the exemplary embodiment of the spin-draw-texturing machine shown in FIG. 1, a plurality of individual threads are each extruded per spinning position 1.1, 1.2 and 1.3, which are then brought together within the machine module by swirling or crimping to form a thread.

The spinning device has per spin position in each case three spinnerets 2.1, 2.2 and 2.3, which are held on an underside of a heated spinneret 6. The spinning beam 6 extends over all spinning positions 1.1, 1.2 and 1.3. The spinning beam 6 is connected via a plurality of melt supply lines 7.1, 7.2 and 7.3 with a plurality of melt sources, not shown here. Each of the melt sources in each case provides a polymer melt which, via the melt feeds 7.1, 7.2 and 7.3 and the distribution system not shown here within the spinning bar 6, is distributed to the individual spinnerets 2.1, 2.2 and 2.3 of the spinning position 1.1, 1.2 and 1.3 with associated spinning pumps , Thus, for example, differently colored polymer melts can be extruded in the spinnerets 2.1, 2.2 and 2.3 to produce, for example, a so-called tricolor thread per spinning position 1.1, 1.2 and 1.3, as is usually required for the production of carpets.

Below the spinning beam 6, a cooling device 3 is arranged, which cooperates in each case with a spinning shaft 4. Here, each spinning position 1.1, 1.2 and 1.3 a spinning shaft 4 with a conical outlet. The cooling device 3 includes a pressure chamber 50, which is coupled via a blowing wall 51 with the spinning shaft 4, so that a transversely directed cooling air flow is generated for cooling the freshly extruded filaments. The pressure chamber 50 is for this purpose connected to a coolant source, not shown here. At this point, however, it should be expressly mentioned that other not shown here Cooling principles for cooling the filaments within the spinning shaft could be used. Thus, so-called blow candles, in which a directed from the inside outward cooling air flow is generated to use for cooling.

Below the spinning shafts 4, the machine modules 5.1, 5.2 and 5.3 are arranged. Each of the machine modules 5.1, 5.2 and 5.3 is identical, so that the structure is explained using the example of the machine module 5.1.

The machine module 5.1 has a frame wall 26, on which a plurality of process units 8 and a discharge unit 9 are held cantilevered. The process units 8 are essentially formed by a preparation device 8.1, a stretching device 8.2, a crimping device 8.3 and a relaxation device 8.4, which are essentially supported on the frame wall 26 with one another. In this case, the components of the process units 8 which are decisive for the thread guide protrude on a front side of the frame wall 26. The electric drives and controls are assigned to the process units 8 opposite on the back of the frame wall 26.

The preparation device 8.1, which may be designed, for example, as a pin preparation or roll preparation, is assigned directly to the outlet of the spinning shaft 4 and combined with a collecting yarn guide 11 which guides the yarns fed via the yarn guides 10 for entry into the machine module 5.1.

The preparation device 8.1 is followed by the stretching device 8.2, which is formed by a withdrawal godet duo 14 and a draw godet duo 15. The withdrawal godet duo 14 and the draw godet duotone 15 each have two driven godets, on the circumference of which the individual threads are guided. The stretching device 8.2 is followed by the crimping device 8.3, which contains a trexturizing nozzle 16 and a cooling drum 17. Within the texturing nozzle 16, the individual textured threads to a common thread and cooled as a thread plug on the circumference of the cooling drum 17.

After cooling, the thread is dissolved from the yarn plug and fed via the relaxation device 8.4 of the winding unit 9. The relaxation device 8.4 contains in each case a plurality of Relaxiergaletten 18.1 and 18.2, which are each formed by a driven godet with associated overflow roller. Between the Ralxiergaletten 18.1 and 18.2 a swirler 19 is arranged to compact the thread before the winding.

It should be expressly mentioned at this point that a second swirling device can preferably be arranged between the preparation device 8.1 and the stretching device 8.2 in order to carry out a preliminary swirling on the individual threads. On the one hand, this makes it possible to even out the preparation application on the multifilament monofilaments and, on the other hand, to influence the mixing of the monofilaments during texturing.

The winding unit 9 is also held on the frame wall 26. The frame wall can in this case be formed in one piece as well as in several parts within the machine module 5.1. To wind the thread, the winding unit 9 has two driven winding spindles 21.1 and 21.2, which are held on a rotatable spindle carrier 20. Through the spindle carrier 20, the winding spindles 21.1 and 21.2 are alternately guided between an operating position and a change position. In the operating position, the winding spindles 21.1 and 21.2 cooperate with a pressure roller 23 and a traversing device 22 in order to wind a thread 24 into a coil 25.

The machine modules 5.1, 5.2 and 5.3 are arranged next to one another and thus form a machine longitudinal side, on which the process units 8 and the winding units 9 are held side by side. For operation of process units

8 is disposed on the front side of the frame wall 26 an access passage 27, the extends over the entire length of the machine longitudinal side, so that an operator from the operating gear 27 can perform all the necessary operations for applying the thread or for the maintenance of process units. Thus, the threads emerging from the spinning shaft 4 during piecing can be taken over, for example, by a manually guided suction gun and placed one after the other in the processing units 8 and winding unit 9 on the machine module. In this case, the operation gear 27 is designed to be increased in order to be able to execute all work operations from a position on the machine module 5.1, 5.2 or 5.3. In the exemplary embodiment illustrated in FIGS. 1 and 2, the operating gear 27 is arranged in a plane which extends between the process units 8 and the winding unit 9. A space for changing the bobbins on the winding unit 9 forms below the operating path 27. The bobbin change on the winding units of the machine modules 5.1, 5.2 and 5.3 is carried out fully automatically by a doffing device 28. For this purpose, the doffer device 28 has a plurality of package changing device 29, wherein each package winding unit 9 is assigned a package changing device 29. The Spulwechselvorrichtung 29 cooperate with a Spulentransporteinrichtung 30, through which the coils are discharged. The bobbin transport device 30 is formed in this embodiment by a bobbin holder 47 which is guided on a monorail 48. The bobbin holder 47 can optionally be placed in each case a transfer position immediately in front of the Spulwechselvorrichtungen 29, so that a full bobbin of the Spulwechselvorrichtung 29 can be transferred. The spool changing device 29 is constituted by a turnstile pivot arm system 42 and a magazine magazine 40. Such a system is described, for example, in German Patent Application 10 2006 010 855 (not previously published). It is thus explicitly taken at this point reference to the cited document and given at this point no further explanation.

In order to obtain a high degree of flexibility in the use of the spinning-stretch texturing machine, the process units 8 and winding units 9 held on the machine modules 5.1, 5.2 and 5.3 are driven independently of each other and controls. For this purpose, the drive and control electronics of the machine modules 5.1, 5.2 and 5.3 are each combined separately in an E-unit 35 and each associated with the machine module 5.1, 5.2 or 5.3. FIG. 2 shows the situation for the machine module 5.1. Here, the E-unit 35 is held on the back of the frame wall 26. The godet drives 31.1, 31.2, 31.3, the roller drive 32 of the cooling drum, the traversing drive 33 of the traversing device 22 and the spindle drives 34.1 and 34.2 of the winding spindles 21.1 and 21.2 and the rotary drive 53 of the spindle carrier 20 are connected to the E-unit 35. Furthermore, further actuators and sensors may be assigned to the process units, which are also linked to the E-unit 35. To control the E-unit 35 is assigned a control unit 37 which is coupled to a control panel 36. The control panel 36 is held on the front of the frame wall 26. Thus, all process units can be controlled by an operator via the control panel 36 in their functions. To coordinate all positions within the spin-stretch texturing, the control unit 37 is coupled to a master control unit 39 through which higher-level control commands and settings can be entered.

It is also possible to connect the control unit 37 wirelessly with an operating device 38. For example, settings and process data or product parameters can be displayed on the operating unit 38. However, it is also possible to specify settings changes or to the processing units and control commands of the control unit 37. For this purpose, the control unit 37 has a remote control module in order to receive and send signals.

In the spin-stretch texturing machine illustrated in FIGS. 1 and 2, the drives and actuators of the spinning device are separately controlled and coupled to the control unit 37 via a central guidance / control unit 39. For this purpose, it is necessary that, in the event of a process interruption, for example due to winding formation, the respective spinning position assigned to the machine module 5.1, 5.2 or 5.3 1.1, 1.2 or 1.3 can continue to operate without interruption. For this purpose, a thread chipper 12 and a suction nozzle 13 are provided on each machine module 5.1, 5.2 and 5.3 respectively in the inlet region. The suction nozzle 13 is coupled to a suction device 49, through which one or more sucked in threads can be continuously fed to a waste container. Thus, a break in the extrusion of the threads is not required in process interruption due to a thread break or a winder formation. Thus, the supply of spinnerets 2.1, 2.2 and 2.3 can be combined with multiple spin positions, so that complex distribution systems and additional spin pump units are dispensable. However, it is also possible to control a spinning position independently of adjacent spinning positions, for example in order to be able to set a reduced melt throughput during a process interruption.

The embodiment of the spin-stretch-texturing machine according to the invention shown in FIGS. 1 and 2 is therefore particularly suitable for producing a plurality of composite threads parallel to one another with high flexibility from melt spinning to winding. Here, the choice of the held on the machine modules process units in Fig. 1 and 2 indicate only by way of example. In principle, additional treatment steps, such as, for example, pre-whirling of the thread immediately after preparation or alternative treatment stages, such as, for example, multiple stretching without texturing, can be carried out. Thus, it is also possible to execute groups of machine modules in different configurations of the process units and treatment steps in a complete system with a large number of machine modules. Thus, different types of thread can be made with a spin-stretch texturing machine.

FIGS. 3 and 4 show a further exemplary embodiment of the device according to the invention in several views. Here, the spinning-stretching texturing machine is shown in a front view in FIG. 3 and in a side view in FIG. see shown. The exemplary embodiment according to FIGS. 3 and 4 is essentially identical to the exemplary embodiment according to FIGS. 1 and 2, so that at this point reference is made to the abovementioned description and only the differences are explained subsequently.

In the embodiment of the spin-stretch texturing machine according to the invention shown in FIGS. 3 and 4, the spinning device 1 has only one spinneret 2 per spinning position 1.1, 1.2 and 1.3. The spinneret 2 of the spinning positions 1.1 and 1.2 and 1.3 are held on the underside of the spinning bar 6 and are supplied via a melt feed 7 with a provided by a melt source polymer melt. The cooling device 3 arranged below the spinning beam 6 and the spinning shafts 4 interacting with the cooling device 3 are identical to the aforementioned embodiment, so that in each case a thread is extruded per spinning position 1.1, 1.2 and 1.3 in the spinning device and subsequently to the machine module 5.1, 5.2 and 5.3 prepared, stretched, curled, relaxed and wound into a bobbin.

In order to be able to create the thread at the start of the process or after a process interruption to the process units 8 of the machine module 5.1, 5.2 or 5.3, a robot 23 is provided. For this purpose, the robot 43 is held on a carrier 44, which is movably coupled to a carrier frame 45. The support frame 45 is held in an upper and lower frame guide 46, which extends at a distance in front of the machine longitudinal side substantially over the entire length of the machine longitudinal side. The support frame 45 can thus be guided on the frame guide 46 along the machine longitudinal side. To start a docking operation on one of the machine modules 5.1, 5.2 and 5.3, the support frame 45 is guided to the relevant machine module. Within the machine module, the carrier 44 can be guided with the robot 43 on the carrier frame 45 in the vertical direction, so that the robot 43 with a multi-axis robot arm 52 can execute the application operation on the processing units 8. The robot arm 52 holds this purpose at the free end of a suction nozzle, through which the extruded threads are taken from the spinning device 1.1, 1.2 or 1.3 after piecing. Subsequently, the application process is carried out through a robot control to Aufspuleinheit.

Thus, a fully automatic operation of the spin-stretch texturing machine can be realized, wherein the bobbin change and the Spulenabtransport is performed in a lower level by the Doffereinrichtung 28. The Doffereinrichtung 28 is identical to the aforementioned Ausführungsbei- game of FIG. 1 and 2 executed here.

The operating gear 27 arranged above the doffer device 28 is preferably used in this case for maintenance work on the process unit.

The embodiments of the spinning stretch texturing machine according to the invention shown in FIGS. 1 to 4 are exemplary in construction and arrangement of the process units and the winding unit. Essential here is the compact design of the machine modules achieved by the vertically oriented arrangement of the processing units and the winding unit, so that compact machine arrangements can be realized even with a single winding, which combine simple and easy operation with maximum flexibility. In particular, the failure rates and thus the unavoidable during a production process interruption can be reduced to a minimum, since in a winder formation or a thread break only one spinning position and thus only one thread is affected. So-called sympathy breaks, as they are known for example in conventional spinning devices are completely avoided.

Depending on the nature and the choice of process units hereby also advantageous uncrimped stretched or partially drawn threads can be produced. In the stretching devices shown in the embodiments, the number and the execution of the godets are basically freely selectable. The design of the stretching device depends on the manufacturing process and on the type of yarn. In addition, the single-thread guide within the machine module and the winding unit leads to a gentle and uniform thread quality, since deflections for merging or spreading, which are usually accompanied by changes in thread tension and thus changes in physical properties avoided. It is thus ensured a gentle and uniform production of the threads.
