Abstract

A device for melt spinning, treating and winding synthetic threads includes a spinning unit, a treatment unit and a winding unit. The spinning unit, the treatment unit and the winding unit are arranged in tiers one above the other and form a plurality of single-thread or multi-thread production positions along the longitudinal side of a machine. To permit a rapid, simple operation, in particular at the start of a process and during interruptions of the process, an operator walkway is located at a height between the treatment device and the winding device.

Description

The invention relates to a device for melt-spinning, treating and winding synthetic threads according to the preamble of claim 1.

In the production of synthetic threads, it is known that a plurality of filaments are extruded from a polymer melt, which are brought together after passing through a cooling section to the thread. Subsequently, a further treatment is carried out essentially by drawing, preparation and turbulence, in order to be subsequently wound up into a bobbin. The devices of such devices usually extend over several floors. Such a device is for example from the DE 103 55 294 A1 known. In this case, a spinning device for extruding and cooling the threads, a treatment device for treating the threads and a winding device for winding the threads to form bobbins are stacked one above the other. The devices along a machine longitudinal side form a plurality of manufacturing positions for simultaneously winding a plurality of threads. In order to obtain the most user-friendly arrangement, the spinnerets are divided into several longitudinal modules in the known device. Thus, with double-sided arrangement, the operation of the spinnerets in the spinning devices can be improved.

In practice, however, the operating instructions in the production of synthetic threads in the area of the treatment device and the take-up device are to be carried out much more frequently, since a thread break requires a new application of the threads each time. Regardless of whether the treatment device and the winding device are arranged one above the other, as shown in DE 103 55 294 A1 is known or as for example from the EP 0 718 424 B1 nested to each other, resulting in particular in the field of treatment facilities operating heights, which are to bridge only by incorporating an additional floor or by additional resources. At the time of the EP 0 718 424 A1 known arrangement of the treatment device and the take-up also occur large machine partitions, which have the disadvantage in particular in a single-threaded process management that the spinnerets required for melt spinning must also be kept at greater distances from each other within a heated spinner. However, such spinning devices require more energy in order to make continuous heating of the melt-carrying components over the entire machine length. Thus, tiered superposed arrangements of the device are preferred to obtain corresponding compact spinners.

From the DE 858 005 C , a machine is known for the production of Kunstseidefäden with several floors for operating the machine. From the FR 2 286 895 A1 , of the EP 0 350 450 A2 and the DE 33 43 714 A1 are melt spinning devices with at least two levels of operation known. From the DE 100 09 335 A1 and the DE 100 39 093 A1 For example, other devices for melt-spinning synthetic threads are known.

It is an object of the invention to provide a device for melt spinning, treating and winding synthetic threads of the generic type, in which in particular the treatment facilities and winding devices are designed to be easy to use.

A further object of the invention is to enable rapid application of the threads in the treatment device and the take-up device in the event of process interruptions.

This object is achieved by a device having the features of the preamble of claim 1, characterized in that for operating the manufacturing positions on the machine longitudinal side an operating gear is arranged at a height between the treatment device and the winding device.

The invention is characterized in that all manufacturing positions can be operated out of an operating level by an operator. Thus, for example, the spun by the spinning device threads take over directly by a manually operated suction gun by the operator and invest in the subsequent aggregates of the treatment device and take-up. It is thus possible to bridge larger heights without additional aids by the operator.

In spite of the separation between the operation of the treatment device and the operation of the take-up device to obtain a quick by the operator, especially at the process start or process interruptions, according to an advantageous embodiment of the invention, at least one passage opening relative to the take-up device in the operating passage, through which a thread guide and thread transfer can take place. The winding device is preferably formed with a winding position with two winding spindles to allow continuous winding of the yarn or threads. Per changing station auxiliary equipment for bobbin replacement are provided, so that the winding device automatically wraps around the coils substantially without manual intervention.

To automate the application process in the winding position is further proposed to provide a movable yarn guide per winding position, which yarn guide between an operating position in the vicinity of the passage opening in the operating gear and a contact position in the vicinity of the winding spindles and is feasible. Thus, the thread can be passed by the operator in a simple manner to the thread guide, which leads the thread for initial application in a designated application position.

The thread guide can in this case be formed, for example, by an injector device which continuously guides a thread transferred by the operator to a waste container. In a particularly cost-effective variant, the yarn guide is formed by a deflection, which is held vertically adjustable on a guide carriage. This allows the thread without transfer lead the manually guided by the operator suction gun during the application process in the winding position.

The application process in the winding position can be further improved in that the auxiliary equipment of the winding point have at least one pivotable Anlegearm which is feasible with a leading end in the thread guide formed by the yarn guide held in the abutment position for the deflection of the thread. Thus, without a manual, provided by the operator support the thread automatically create for winding a coil in the winding position. In this case, the thread guide can be designed to guide a thread or to guide a plurality of threads.

The automation of the device according to the invention can be further improved by the development of the invention in that the winding stations Doffeinrichtung is assigned for the removal and removal of the coils.

The manufacturing positions for melt-spinning, treating and winding one or more threads can be used particularly flexibly, in which, according to a further preferred development, the winding positions of adjacent production positions can be driven and controlled independently of one another. This can be avoided in a variety of threads so-called Sympathiefadenbrüche advantageous so that the fast and easy operation in addition to the individual control of the aggregates of manufacturing positions lead to very low amounts of waste.

The treatment units are preferably also driven and controlled independently, so that the required operating and maintenance work can be performed quickly and efficiently in the production positions.

In order to obtain the most user-friendly arrangement of treatment units, the treatment units are arranged on a frame wall, so that there is a separation between the thread-guiding components and the drives and electronic components, the drives and controls are preferably formed on a rear side of the frame wall and the Guide the thread required assemblies are held on a front side of the frame wall.

The device according to the invention is particularly suitable for continuously winding spun-spun threads into coils after a single-stage or multistage treatment, the user-friendly design leading in particular to avoiding large production interruptions and thus avoiding waste quantities during production stoppages. The treatment units of the treatment facilities may include by godets, swirling device, preparation device, suction devices, thread monitor and combinations of such aggregates. The device according to the invention can also be used particularly advantageously for producing crimped threads. Thus, per processing position additional treatment units such as texturing and cooling drum are available.

The device according to the invention will be explained in more detail below with reference to some embodiments with reference to the attached figures.

In Fig. 1 and Fig. 2 a first embodiment of the device according to the invention for melt-spinning, treating and winding synthetic threads is shown in several views. In Fig. 1 is a schematic front view and in Fig. 2 schematically shown a side view of the device. Unless an explicit reference is made to one of the figures, the following description applies to both figures.

The device is formed in this embodiment by a spinning device 1, a treatment device 8 and a winding device 9, which are arranged one above the other in a stack. The spinning device 1, the treatment device 8 and the winding device 9 form a total of three manufacturing positions 1.1, 1.2 and 1.3, to spin several threads side by side in parallel, treat and wind to coils. The number of manufacturing sites is exemplary. In principle, such devices may have a variety of manufacturing positions to produce a plurality of threads simultaneously. For each production position 1.1, 2.1 and 1.3, a total of two threads 24.1 and 24.2 are spun, treated and wound simultaneously.

The spinning device 1 has per production position 1.1, 1.2 and 1.3 each two spinnerets 2.1. The spinnerets 2.1 and 2.2 are held on an underside of a heated spinning beam 6. The spinning beam 6 extends over all production positions 1.1, 1.2 and 1.3, so that the spinnerets 2.1 and 2.2 are each arranged in two row-shaped nozzle arrangements. The spinning beam 6 is connected via a melt feed with a melt source, not shown here. Through the melt supply 7 is a polymer melt by a distributor system not shown here with assigned Spinning pump distributed to the individual spinnerets 2.1 and 2.2 of the manufacturing positions 1.1, 1.2 and 1.3.

Below the spinning beam 6, a cooling device 3 is arranged, which cooperates in each case with a spinning shaft 4. In this case, each production position 1.1, 1.2 and 1.3 has a spinning shaft 4 with a conical outlet. The cooling device 3 is designed as a cross-flow blowing, in which a transverse cooling air flow is generated for cooling the freshly extruded filaments. It should be expressly mentioned at this point that other cooling principles, not shown here, could also be used for cooling the filaments within the spinning shaft. 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 treatment device 8 is arranged. The treatment device 8 has, per production position 1.1, 1.2 and 1.3, in each case a preparation device 8.1 and a stretching device 8.2. The stretching device 8.2 is arranged downstream of the preparation device 8.1 and 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 at least one driven galette, on the circumference of which the individual threads are stirred in multiple wraps.

The preparation device 8.1, which may be designed, for example, as a pin preparation or as a roll preparation shown here, is assigned directly to the outlet of the spin shaft 4 in the production position 1.1, 1.2 or 1.3 and combined with a convergence yarn guide 5 which extrudes the through the spinneret 2.1 and 2.2 Filaments to a thread 24.1 and 24.2 merges.

The treatment units of the treatment device 8 are arranged on a frame wall 26. In this case, the components of the treatment units 8.1 and 8.2 which are decisive for the thread guide protrude to a front side of the frame wall 26. The electric drives and control are arranged opposite each other on the back of the frame wall 26. In principle, there is the possibility that the treatment device has even wider treatment units such as turbulators or alternative treatment units such as individual godets. In that regard, the in Fig. 1 and Fig. 2 illustrated treatment device 8 by way of example.

The winding device 9 is also held on the frame wall 26. The frame wall 26 may for this purpose be formed in one piece or in several parts. The take-up device 9 has, for each production position 1.1, 1.2 and 1.3, a winding point which has two driven winding spindles 21.1 and 21.2 for winding the two threads. The winding spindles 21.1 and 21.2 are held on a rotatable spindle carrier 20. Through the spindle carrier 20, the winding spindles 21.1 and 21.2 of the winding stations 10.1, 10.2 and 10.3 are guided alternately 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 the threads 24.1 and 24.2 into a respective coil 25.1 and 25.2.

Each of the winding stations 10.1, 10.2 and 10.3 respectively has auxiliary devices 38 in order to be able to carry out a bobbin change automatically. The auxiliary device 38, which is formed as an example by a Abschiebegabel for coils, also has a Anlegearm 39, which is held laterally next to the winding spindles 21.1 and 21.2 and supports the first application of a thread in a pivotable axis. The function of the Anlegearmes 39 will be explained in more detail below.

To operate the manufacturing positions 1.1, 1.2 and 1.3, in particular when creating a thread in the treatment device 8 and in the winding device 9, an operating passage 27 is arranged at the machine longitudinal side between the treatment device 8 and the take-up device 9. The operation gear 27 extends over the entire length of the machine longitudinal side, so that an operator from the operation gear 27 can perform all the necessary operations for applying the thread or for the maintenance of the treatment units 8.1 and 8.2. Thus, when piecing, the yarns 24.1 and 24.2 leaving the spinning shaft 4 can take on one of the production positions 1.1, 1.2 or 1.3 by means of a manually guided suction gun and place one after another in the treatment units 8.1 and 8.2. Due to the elevated position of the operating gear 27 on the machine longitudinal side, all working operations can be carried out from one position by an operator.

In the field of winding stations 10.1, 10.2 and 10.3, the operating gear 27 each have a passage opening 28, which allows a yarn transfer and a yarn path during a docking operation. For thread transfer to the trained below the operation 27 winding position the winding stations 10.1, 10.2 and 10.3 are each assigned a movable yarn guide 29. The movable yarn guide 29 can thereby lead between an operating position and a contact position. In Fig. 1 and Fig. 2 the yarn guide 29 is shown in an operating position in the vicinity of the passage opening 28. The movable yarn guide 29 is formed in this embodiment by a deflection means 31 which is projectingly connected to a guide carriage 32. The deflection means 31 may be formed for example by a deflection pin or a deflection roller. The guide carriage 32 is guided in the vertical direction on a guide rail 33 and can thus be moved between the operating position and a lower application position. For further explanation of the function of the movable yarn guide 29 will be discussed in more detail below.

In Fig. 3 is an embodiment of the winding station 10.1 in Fig. 1 and 2 shown winding device 9 shown in a situation in which a thread to Start process is applied to one of the winding spindles for winding a coil. The situation here is shown on the yarn path of only one thread.

At the beginning of the application process, the movable yarn guide 29 is held in the vicinity of the passage opening 28 in its operating position. For thread guidance, the yarn guide 29 has a deflection means 31, which is held on the guide carriage 32. Now, the thread 24 is continuously withdrawn via a manually guided suction gun 34 from the spinning device 1 and guided to a waste container. First, the thread 24 is successively inserted into the treatment units 8.1 and 8.2 of the treatment device 8, to be threaded at the end in a head thread guide 30. Then, an operator guides the suction gun 34 with the thread 24 in a loop around the deflection means 31 and remains with the suction gun 34 in a waiting position. The thread 24 is thereby threaded into the movable yarn guide 29. By operating elements in the region of the treatment device 8, the operator triggers the drive of the guide carriage 32, so that the yarn guide 29 moves vertically from the operating position into the application position downwards. The application position is in Fig. 3 shown in dashed lines in the lower region of the guide rail 33. Here, the leading end of the yarn guide 29 is held in the vicinity of the winding spindles 21.1 and 21.2. The yarn path between the head thread guide 30, the deflection pin 31 and the suction gun 34 is also shown in dashed lines. Now, in the further course of the application process, the feed arm 39 of the auxiliary device of the winding point 10.1 is activated, so that a leading end 40 of the feed arm 39 with increasing pivot angle in the yarn path of the guided between the head thread guide 30 and the deflection means 31 thread 24 applies. The leading end 40 of the Anlegearmes 39 takes the thread and deflects it in the direction of the winding spindle 21.1. The winding spindle 21.1 holds a winding tube with a catching means, so that the thread 24 is grasped and severed. The winding cycle of the winding station 10.1 begins. Thus, the operation of the take-up device 9 can advantageously be carried out of the operation gear 27 out.

In the Fig. 4 and 5 is a further embodiment of the device according to the invention shown in several views. In Fig. 4 schematically a front view and in Fig. 5 schematically shown a side view of the device. Unless an explicit reference is made to one of the figures, the following description applies to both figures.

The embodiment is in turn composed of a spinning device 1, a treatment device 8 and a take-up device 9. The spinning device 1, the treatment device 8 and the winding device 9 are combined to a total of three production positions 1.1, 1.2 and 1.3 with a single-thread guide per production position.

The spinning device 1 contains for each production position 1.1 and 1.2 and 1.3 respectively three spinnerets 2.1, 2.2 and 2.3, which are held on an underside of a heated spinneret 6. The spinning beam 6 in this case carries the spinnerets 2.1 to 2.3 of the manufacturing positions 1.1 to 1.3 in a single-row arrangement. 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 a polymer melt is provided which distributes the melt supply 7.1, 7.2 and 7.3 and the distribution system not shown here within the spinning beam 6 with associated spinning pumps on the individual spinnerets 2.1, 2.2 and 2.3 of the manufacturing positions 1.1, 1.2 and 1.3. Thus, for example, differently colored polymer melts can be extruded in the spinnerets 2.1, 2.2 and 2.3 in order, for example, to produce a so-called tricolor thread per manufacturing position 1.1, 1.2 and 1.3, as is usually required for the production of carpets. Thus, the filament bundles of the spinnerets 2.1, 2.2 and 2.3 in each of the manufacturing positions 1.1, 1.2 and 1.3 are each combined to form a thread.

The arranged below the spinning beam 6 cooling device 3 is identical to the preceding embodiment according to Fig. 1 and 2 , so that no further explanation will be given here.

Below the spinning shafts 4, the treatment device 8 is arranged with their treatment units 8.1, 8.2, 8.3 and 8.4. Per manufacturing position 1.1, 1.2 and 1.3, the treatment device 8 each have a preparation device 8.1, a stretching device 8.2, a crimping 8.3 and a relaxation 8.4, which are held substantially to one another on a frame wall 26. In this case, the components of the treatment units which are decisive for the thread guide protrude on a front side of the frame wall 26. The electric drives and controls, however, are held on the opposite side of the frame wall 26.

The preparation device 8.1 is upstream of the stretching device 8.2, which is formed by a withdrawal godet duo 14 and a draw godet duo 15. The stretching device 8.2 follows the crimping device 8.3, which contains a texturing nozzle 16 and a cooling drum 17. Within the texturing nozzle 16, the monofilaments are textured into a common thread and cooled as a thread plug on the circumference of the cooling drum 17. After cooling, the thread is dissolved out of the yarn plug and fed to the take-up unit 9 via the relaxation device 8.4. The relaxation device 8.4 contains in each case a plurality of Relaxiergaletten 18.1 and 18.2, which are each formed to a driven godet with associated overflow roller. Between the Relaxiergaletten 18.1 and 18.2 a swirler 19 is arranged to compact the thread before the winding.

The winding device 9 is in their Wickestellen 10.1, 10.2 and 10.3 substantially identical to the embodiment according to Fig. 1 and 2 executed, wherein per winding position 10.1, 10.2 and 10.3 only one thread 24 is wound into a coil 25. To explain the structure and function of the winding stations 10.1, 10.2 and 10.3 will become to the foregoing description of the embodiment according to Fig. 1 and 2 Referenced

In the height between the treatment device 8 and the take-up device 9 extends along the machine longitudinal side of the operation gear 27, which opposite each of the winding stations 10.1, 10.2 and 10.3 each have a passage opening 28. In that regard, the thread transfer takes place during initial application via the passage opening 28. Below the access passage 27, a free space for changing the coils at the winding locations 10.1, 10.2 and 10.3 is formed. The bobbin change at the winding stations 10.1 to 10.3 is performed fully automatically by a doffing device 42. The doffing device 42 has for this purpose a plurality of Spulwechselvorrichtungen 43, wherein in the winding position 10.1 to 10.3 one of the Spulwechselvorrichtungen 43 is associated. The Spulwechselvorrichtungen 43 cooperate with a Spulentransporteinrichtung 44. By the bobbin transport device 44 taken at the winding stations 10.1 to 10.3 coils 25 are discharged. The bobbin transport device 44 is formed in this embodiment as a monorail. The Spulwechselvorrichtung 43 is formed by a Drehkreuzarmsystem, for example from the German patent application 10 2006 010855 (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 flexibility in the use of the device, the production positions 1.1, 1.2 and 1.3 are driven and controlled independently with their treatment units and winding stations. For this purpose, the drive and control electronics of the manufacturing positions 1.1 to 1.3 are each combined separately in an E-unit 35 and each assigned to the manufacturing position 1.1 to 1.3. In Fig. 5 the situation for the manufacturing position 1.1 is shown. Here, the E-unit 35 is held on the back of the frame wall 26. The godet drives, the roller drive of the cooling drum, the traversing drive, the spindle drives of the winding spindles and the rotary drive of the spindle carrier 20 are connected to the E-unit 35. Furthermore, even more actuators and sensors can be assigned to the treatment 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 in a control panel 36. The control panel 36 held on the front of the frame wall 26, thus all process units can be controlled by an operator on the control panel in their function. The control panel 36 is located in the area of the treatment device 8, above the operating gear 27th

In order to be able to operate the spinning device 1 without interruptions in the event of a yarn break in one of the production positions 1.1, 1.2 or 1.3, a yarn chopper 12 and a suction nozzle 13 are assigned to each production position 1.1, 1.2 and 1.3 in the inlet region of the treatment device 8. The suction nozzle 13, which is connected to a waste container, and the thread chipper 12 cooperate in order to remove the threads from the spinning device in the event of a process failure.

This in Fig. 4 and 5 illustrated embodiment of the device according to the invention is particularly suitable to produce a plurality of composite threads in parallel side by side with high flexibility from quick-spinning to winding. Here, the choice of the treatment units held at the production positions is only an example. In principle, additional treatment steps, such as, for example, pre-whirling of the thread immediately after preparation or alternative treatment stages, such as multiple drawing without texturing, can be carried out. So it is also possible to perform in a complete system with a variety of manufacturing positions groups of individual production positions in different training of process units and treatment steps. Thus, different types of thread can be made with a device.
