Description

  The present invention relates to an apparatus for pulling out and winding up a yarn group in a melt spinning process according to the preceding stage of claim 1.

  When producing synthetic yarns by a melt spinning process, as is generally known, yarns are godet systems with multiple godets and processing equipment for further processing after melt spinning and cooling. To be supplied. For this reason, in a recent apparatus, the godet system is designed to cooperate with the winder, and therefore a compact arrangement of the godet is required. At this time, it is desired that the godet system and the winder can be operated from one operation path without a large auxiliary means.

  Such a device is known, for example, on the basis of German Offenlegungsschrift DE 101010146647. In this known device, the godet system is arranged in a godet module, which is held directly on the winder by a machine frame. The godet module and the winder each have one operation panel, which is disposed on the operation side and can be operated from the operation passage by an operator. The godet system has a plurality of heated godets and an unheated godet, and these godets are held by protruding on a holding wall. At this time, the number and type of godets are mainly related to each manufacturing process. For example, as is generally known, in order to produce a fully drawn yarn, multiple godets are required for drawing and subsequent relaxation. At this time, the critical conditions of the processing steps necessary for this purpose must be maintained.

  For example, in a device for processing yarn known from WO 13078744, the godets of the godet system are arranged in one common processing chamber. A processing apparatus that supplies oil to the yarn, which is disposed on the downstream side of the godet system, is disposed in an adjacent processing chamber separately from the godet. Depending on the yarn material, different thermal conditions must be created by the godets in order to be able to carry out drawing and subsequent relaxation in the yarn. Thus, the godet peripheral wall of the godet is heated to different surface temperatures depending on the process and yarn material. In order to avoid obtaining a wide range of processing results, the temperature regulation of the yarns made through the godet peripheral wall, in particular based on the godet's common ambient environment, must be maintained within the narrowest possible error range. .

  The object of the present invention is therefore to improve the known device for drawing out and winding up a group of yarns and to provide a device in which the heat treatment necessary for the yarn is possible even with a very compactly arranged godet. .

  Another object of the invention is to ensure an environment that is as easy to operate as possible for the operator to carry out all the operating steps.

  In order to solve this problem, in the configuration of the present invention, the godet in the holding wall including the godet peripheral wall adjusted in high temperature and the godet including the godet peripheral wall adjusted in low temperature are arranged to be insulated from each other. .

  Preferred embodiments of the invention are determined by the features and combinations of features of the respective dependent claims.

  The present invention is based on the recognition that a high speed difference is required between the individual godets of a godet system based on normal drawing conditions when producing fully drawn yarns. Therefore, the godet heated to relax the yarn must have a significantly higher surface temperature in order to be able to perform a sufficient heat treatment on the yarn based on the high peripheral speed and the relatively short contact time. It is. By disposing the godet peripheral wall adjusted at a high temperature in a state of being insulated from the godet peripheral wall adjusted at a low temperature, it is possible to prevent the temperature adjustment of the godet that stretches and relaxes the yarn from affecting each other.

  This is because the godet's high-temperature-adjusted godet peripheral wall is arranged in the high-temperature chamber of the godet box held by the holding wall, and the godet's low-temperature-adjusted godet peripheral wall is arranged in the low-temperature chamber of the godet box. Can be further improved. When configured in this way, additional thermal insulation between the godets can be suitably used to produce a corresponding ambient temperature for the heat treatment for stretching and relaxation. Furthermore, the godet adjusted at a high temperature can be suitably moved away from the operation environment of the intensive operation process.

  Insulation between the high and cold rooms can only be interrupted by at least one or more thread passage openings.

  In a preferred embodiment of the present invention, the cryogenic chamber is divided into a warm zone and a cold zone inside the godet box, in order to keep the subsequent processing and its processing equipment away from the operating environment. At least one processing device is arranged in the zone. If comprised in this way, the possibility of cut | disconnecting the godet provided with the godet surrounding wall which is not heated from the godet provided with the godet surrounding wall adjusted low temperature is acquired.

  The control of the godet and the control of the winder are preferably performed using an operation panel that is arranged corresponding to one operation side and can be operated from one operation path. At this time, the operation panel is arranged on the side by the cold room of the godet box, thereby preventing the electronic control unit from being undesirably subjected to a heat load.

  In order to be able to directly operate the interface to the spinning device arranged on the upstream side, which is usually formed by the yarn driving device, in another aspect, in the vicinity of the operation panel that controls the godet, A yarn threading device is formed in the godet module. If comprised in this way, the operator can also operate the suction pistol guided manually for delivering a thread group simultaneously with the key operation in an operation panel. Thereby, an extremely short failure time can be realized when the process is interrupted.

  In order to be able to continuously receive a group of yarns from the spinning device in the event of an incorrect change or breakage in the winder, the yarn run-in device has at least one movable, multi-yarn yarn guide, It has a cutting device and a suction device. If comprised in this way, by moving a thread | yarn guide, the whole thread | yarn group can be guided in the cutting device and the suction device which cooperates with this cutting device. This step is preferably performed in an automated manner by the monitoring sensor, at which time the operator directly accesses the operation panel.

  The yarn entering device is preferably held by a holding wall of the godet module, and an operation panel for controlling the godet is formed in the godet module in a direction transverse to the holding wall. If comprised in this way, the operation panel which controls a yarn entering device and a godet can be directly operated from an operation path.

  In order to wind up as many yarns as possible, in another preferred embodiment of the invention, the godets of the godet module are arranged corresponding to two winders arranged mirror-symmetrically with respect to each other. With such a configuration, it is possible to limit the protruding length of the winding spindle despite the large number of yarns.

  Next, an embodiment of an apparatus according to the present invention will be described in detail with reference to the drawings.

The winding machines 1.1 and 1.2 have the same structure, and are positioned so as to face each other in mirror symmetry. Accordingly, the structure of the winding machines 1.1 and 1.2 will be described only for one winding machine 1.1. The winding machine 1.1 has a winding revolver 3. The take-up revolver 3 is rotatably supported by the machine frame 13 and can be driven by the revolver driving device 6. The take-up revolver 3 has a first take-up spindle 4 and a second take-up spindle 5 that is arranged 180 ° apart. The winding spindles 4, 5 are swung alternately from the operating zone to the exchange zone or vice versa by the winding revolver 3 in order to wind up the yarn continuously.

  The winding spindles 4 and 5 are formed so as to be able to be driven independently of each other. At this time, the winding spindle 4 is driven by a spindle driving device 7 and the winding spindle 5 is driven by a spindle driving device 8. The

  1 and 2, the winding spindles 4 of the winding machines 1.1 and 1.2 are respectively shown in the operating region, whereby the group of yarns 2.1 and 2.2 to which they belong are arranged in a plurality of packages 11. Can be wound up. The second winding spindle 5 is held in the replacement area, and at this time, the package 11 has already been replaced with the empty tube 12.

  In the operation region, a pressure roller 9 is arranged correspondingly to the winding spindles 4 and 5, and this pressure roller 9 is in contact with the surface of the package 11 during winding of the yarn. The pressure roller 9 is rotatably held by a roller support 10. At this time, the roller support 10 is formed to be movable in a machine frame 13.

  As can be seen from the illustration in FIG. 2, the winder 1.1 has four winding units 33, so that each yarn group 2.1 has four single yarns. The number of winding units 33 for each of the winding machines 1.1 and 1.2 for determining the number of yarns for each yarn group is an example. Basically, more winding units 33 may be formed on the winding spindle in parallel with each other. For example, 10, 12 or more yarns can be wound into a package in parallel using a winding spindle.

  In order to be able to wind a yarn and form a traversing package, the winder 1.1 has a traversing device 14 which is arranged upstream of the pressure roller 9. Has been. For each yarn, the traversing device 14 has yarn guide means, which can guide the yarn back and forth inside the winding unit 33. The supply of the yarn is performed via a head yarn guide 15. The head yarn guide 15 is disposed on the traversing device 14, and each yarn has a guide element. In the present embodiment, the guide element of the head yarn guide 15 is formed as a turning roller.

  In order to control the drive device, each winder 1.1, 1.2 has a separate control device, indicated at 17 in FIG. This control device 17 has a controller for controlling a godet motor of the godet system 21 arranged on the upstream side in addition to a controller for the drive device of the winder 1.1, 1.2. Can have. The control device 17 is connected to one operation panel 20.1, 20.2 of each of the winders 1.1, 1.2.

  As is clear from the illustrations in FIGS. 1 and 2, a holding frame 24 is provided between the winders 1.1, 1.2 and the godet module 16. A godet module 16 is held immediately above the winders 1.1, 1.2.

  To describe the godet module 16, reference is additionally made to FIGS. 3 and 4. 3 is a front view schematically showing the godet module 16 of the embodiment shown in FIG. 1, and FIG. 4 is a side view schematically showing the godet module 16 of the embodiment shown in FIG. is there. Accordingly, the following description is for FIGS.

  The godet module 16 has a godet system 21 having a plurality of godets arranged on the holding wall 17. On the front side of the holding wall 17, a plurality of heated godet peripheral walls of the godet 22 and a plurality of cold or room temperature godet peripheral walls of the godet 23 are held in a protruding manner. At this time, a plurality of godet motors 25 for driving the godet peripheral walls of the godets 22 and 23 are arranged on the back side of the holding wall 17. Accordingly, the godet module 16 has a partition between the yarn guide portion and the drive portions of the godets 22 and 23. The godets 22 and 23 are controlled through an operation panel 19 disposed on the end face of the holding wall 17.

  The heated godet peripheral wall of the godet 22 is disposed inside the godet box 28. For this purpose, the godet box 28 shown without a door at the end face of the godet 22 has an upper hot chamber 34 and a lower cold chamber 35 formed on the front side of the holding wall 17 for that purpose. Yes. In the upper high temperature chamber 34, the godet peripheral walls 22.2, 22.3, 22.4 of the heated godet 22 are arranged at a high temperature. The high greenhouse 34 is formed in the upper half of the godet module 16. The low temperature chamber 35 located therebelow is divided into a warm zone 38.1 and a cold zone 38.2 in this embodiment. Arranged in the warm zone 38.1 is a godet peripheral wall 22.1 of another heated godet 22 which has been chilled. For the yarn guide, the godet box 28 has a yarn inlet opening 36.1 and a yarn outlet opening 36.2. The low greenhouse 35 is connected to the high temperature chamber 34 through a plurality of yarn passage openings 39.1 and 39.2. The yarn inlet opening 36.1 and the yarn outlet opening 36.2 are formed in the lower cold chamber 35, respectively.

  The heated godets 22 in the low greenhouse 35 and the high temperature chamber 34 are used for yarn stretching and relaxation. In this case, a stretching zone is formed between the godet peripheral wall 22.1 adjusted at low temperature and the godet peripheral wall 22.2 adjusted at high temperature. Subsequent godet peripheral walls 22.3 and 22.4 form a post-processing zone, in which the yarn group is guided along the godet peripheral wall adjusted at a high temperature. Accordingly, a relatively high temperature level is generated in the surroundings in the high temperature chamber 34, and such a temperature level is insulated from the environment in the low temperature chamber 35 by the chamber wall. The heated godet 22.1 in the low greenhouse 35 is usually heated to a clearly lower surface temperature to warm the yarn group. At this time, the surface temperature of the godet peripheral wall 22.1 adjusted at low temperature is in the range of 40 ° C to 150 ° C.

  On the other hand, the godet peripheral walls 22.2 to 22.4 adjusted at high temperature have a relatively high temperature level. The surface temperature of the godet peripheral wall 22.2 to 22.4 adjusted at high temperature is in the range of 120 ° C to 250 ° C.

  As can be seen in particular in the illustrations of FIGS. 2 and 4, in the cold zone 38.2 of the cold chamber 35, another unheated godet 23 and additional processing devices are arranged. In the present embodiment, the processing device is formed by the oil supply device 26 and the entanglement device 27.

  Since the godet box 28 is closed by the door 40, the high temperature chamber 34 and the low temperature chamber 35 are shielded from the surroundings. The door 40 is only shown in FIG.

  As is apparent from the illustrations of FIGS. 1 to 4, the yarn entering device 18 is formed in the godet module 16 in the immediate vicinity of the operation panel 19. In this embodiment, the yarn entering device 18 includes a movable multi-yarn yarn guide 29, a turning yarn guide 32, a cutting device 31, and a suction device 30, which are arranged on the front side of the holding wall 17. ing. For this purpose, the yarn threading device 18 is arranged in the region of the cold room 35 at the side near the godet box 28 and directly arranged in correspondence with the operation passage 37. As can be seen in particular in FIG. 2, the operating passage 37 extends parallel to the end surfaces of the godet module 16 and the winders 1.1, 1.2. Accordingly, the operation panel 19 of the godet module 16 is directed directly to the operation passage 37 in the same manner.

  In order to draw the yarn group from the spinning device arranged on the upstream side, which is not shown in detail here, a plurality of godet peripheral walls of the godet 23 that are not heated are correspondingly arranged in the yarn entering device 18. The godet 23 is held on the holding wall 17 so as to protrude from the side near the godet box 28. Similarly, one godet motor 25 is correspondingly disposed on the godet peripheral wall of the godet 23 on the opposite side of the holding wall 17 from the godet 23.

  1 to 4 show an embodiment of the device according to the invention in an operating situation in which the godet system 21 pulls the yarn group 2 out of the spinning device. The yarn is guided by the godet module 16 via the yarn run-in device 18 and supplied to the heated godet 22 inside the godet box 28 via the unheated godet 23.

  Usually, at the start of the process, the operator stores the yarn continuously extruded in the spinning device using a suction pistol, and places it on the godets 22 and 23, the processing devices 26 and 27, and the winding position. At the same time, the operation of the drive device can be operated by the operator via the operation panels 19, 20.1 and 20.2. At this time, the operation panel 19 in the godet module 16 can also implement the control functions of the winders 1.1 and 1.2. The operation panels 19, 20. 1, 20.2 arranged around the operation area of the operator are arranged with a large interval with respect to the high temperature chamber 34.

  If an incorrect replacement or yarn breakage occurs at one of the winding points during operation, the yarn entry device 18 is actuated via a monitoring sensor (not shown) and a yarn guide 29 for multi-yarns. Delivers the yarn group 2 to the cutting device 31 and the suction device 30. After the yarn residue has been removed, the yarn group is again delivered from the yarn run-in device 18 by a manually guided suction pistol, guided by the operator, and placed at the winding point of the godet and winder. .

  In the embodiment shown in FIGS. 1 to 4, the cold chamber 35 of the godet box is arranged in the lower region, thereby making the ambient environment for the operating elements and the operator as heat load as possible. It can be kept unaffected. Therefore, the high temperature chamber 34 is formed in the upper region of the godet box. However, basically, the high temperature chamber 34 and the low temperature chamber 35 can be arranged in the same plane, and at this time, the high temperature chamber is preferably arranged in a region opposite to the operation passage. To that end, FIG. 5 schematically shows another embodiment of the device according to the invention. Since the rest of the apparatus, in particular the winder, is constructed the same as the embodiment of FIG. 1 already described, FIG. 5 shows the godet module 16 in a side view. Therefore, only the configuration of the godet module 16 will be described in detail below.

  In the embodiment shown in FIG. 5, a plurality of godets 22 and 23 are arranged on the holding wall 17. In FIG. 5, the unheated godet is indicated by reference numeral 23, and the heated godet is indicated by reference numeral 22. The number and arrangement of the godets 22 and 23 are an example. For example, in order to draw out the yarn group 2 from the melt spinning apparatus arranged on the upstream side, two cold or room temperature godets 23 are provided on the run-in side. On the downstream side of the room temperature godet 23, four heated godets 22 are arranged on the yarn path, and the first heated godet 22 having the heated godet peripheral wall 22.1 is a low-temperature godet 22. The peripheral wall surface of this low-temperature godet is heated to a temperature in the range of 40 to 150 ° C. The subsequent heated godet 22 with the heated godet peripheral wall 22.2, 22.3, 22.4 forms a so-called high temperature godet, and the peripheral wall surface of this high temperature godet is 120 ° C to 250 ° C. Is heated to a temperature in the range.

  The godet peripheral walls 22.1 to 22.3 projectingly held on the holding wall 17 are shielded against the surroundings by the godet box 28. At this time, the high temperature godet including the godet peripheral walls 22.2 to 22.4 is The low temperature godet disposed in the high temperature chamber 34 and including the godet peripheral wall 22.1 is disposed in the low temperature chamber 35. At this time, the low temperature chamber 35 is divided into a warm zone 38.1 and a cold zone 38.2, and the normal temperature godet 23 arranged upstream of the low temperature godet 22 is in the cold zone 38.2 of the low temperature chamber 35. Is held in.

  Under the high greenhouse 34 and the low temperature chamber 35, the godet box 28 has a processing chamber 41, which extends under the high temperature chamber 34 and the low temperature chamber 35. The processing chamber 41 serves to accommodate another godet 23 and a plurality of processing assemblies that are not heated to perform further processing steps in the yarn group 2 after drawing and relaxation. In the present embodiment, the oil supply device 26 and the entanglement device 27 are held in the processing chamber 41 as the processing device.

  For the yarn guide, the godet box 28 has a yarn inlet opening 36.1 and a yarn outlet opening 36.2. Inside the low greenhouse 35, the warm zone 38.1 and the cold zone 38.2 are likewise separated from each other by a partition wall, at which time the yarn passes between both zones via a yarn passage opening 39.1. Be guided in.

  The entry into the high greenhouse 34 is possible via a separate thread passage opening 39.2. Further, the yarn enters from the high temperature chamber 34 into the processing chamber 41 of the godet box 28 through another yarn passage opening 39.3. For thermal insulation, the hot chamber 34 has a thermal insulation 42, which on the one hand avoids heat loss and on the other hand obtains as stable an ambient environment as possible inside the hot chamber 34. it can.

  The yarn entry device 18 is correspondingly arranged at the yarn inlet of the godet box 28. The yarn introduction device 18 is the same as the embodiment shown in FIG. Now, further explanation will be omitted and the explanation above will be referred to. An operation panel 19 of the godet module 16 is disposed on the side of the godet box 28 facing the operation passage. Also in this embodiment, the operation panel 19 is located in the immediate vicinity of the low temperature chamber 35.

  In the embodiment shown in FIG. 5, the driving devices for the godets 22 and 23 are arranged on the back side of the holding wall 17. Since the godet box 28 held on the front side of the holding wall 17 is closed by a door (not shown), the protruding peripheral wall of the godet and the processing apparatus are completely insulated from the surroundings and held by the holding wall 17. ing.

  Due to the easy-to-operate arrangement and compact configuration of the godet module 16, the device according to the invention is particularly easy to operate, so that, for example, process interruptions after a failure can be eliminated as quickly as possible. Furthermore, the arrangement configuration in which the godet with the godet peripheral wall adjusted at a high temperature is insulated from the godet with the godet peripheral wall adjusted at a low temperature adjusts the temperature of the yarn necessary for each processing step. Particularly suitable for maintaining. For example, it is preferred that the yarns of the yarn group can be adjusted to different temperatures for drawing and subsequent relaxation treatments without causing mutual effects.
