Description

  The invention relates to a textured machine for crimping yarns of the type described in the superordinate concept of claim 1.

  This type of textured machine is used for crimping and drawing the smooth yarn being fed, i.e. the raw yarn, in a textured process. For this purpose, the textured machine has a plurality of process units and a winding device in one of a plurality of work places. The process unit and the winding device are arranged in the machine frame in combination with the yarn traveling path. Process units such as delivery mechanisms, heating devices, cooling devices, textured units, entanglement devices and lubrication devices are often arranged in two layers in the machine frame. Therefore, known textured machines require special auxiliary devices to feed the raw yarn to the process unit to the winding at the start of the process. That is, for example, it is known from French Patent Publication No. 2380972 or French Patent Publication No. 29665631 to guide the yarn through a guide tube in a pneumatic manner for initial feeding. That is, the yarn is guided through the guide tube to just before the winding device, and blown out from the discharge opening at the end of the guide tube. At this time, the collision plate is arranged at a distance from the discharge opening in the discharge direction. The impingement plate causes the yarn to turn to the winding device. Within the winding device, the yarn is then taken up by a suction device.

  However, the general disadvantages of the known devices are that the yarn undergoes a change in directionality only during a very strong discharge action, or a loose yarn reception is still possible only with a very high suction action. It is in that point. In addition, the problem arises that the yarn remains constrained by the impingement plate based on the residual lubrication attached to the yarn from the pretreatment.

  The object of the present invention is therefore to improve a textured machine of the type mentioned at the outset so that the yarn is automatically guided to the winding device in a simple manner with great certainty before the start of the process. It is to be possible or deliverable.

  According to the present invention, there is provided a textured machine having the features described in the characterizing portion of claim 1 and an initial feeding of a yarn to a winding device having the features described in the characterizing portion of claim 8. It is solved by the method of feeding.

  Advantageous configurations of the invention are defined by the features and feature combinations of the dependent claims.

  The invention is advantageous in that the yarn is guided for hanging on the winding device without turning. For this purpose, the discharge opening of the guide tube and the receiving opening of the suction device are arranged to face each other. In this case, the guide tube is formed so as to be adjustable so that the discharge opening can be held at a plurality of positions relative to the receiving opening for hanging and feeding the yarn. In this way, the function “hanging the yarn” and the function “aligning” are advantageously carried out from different positions. In particular, it should be noted that when the yarn is blown from the discharge opening, a loose yarn end can be reliably received by the receiving opening of the suction device. For this purpose, it is necessary that the arrangement between the discharge opening and the receiving opening, which are located opposite to each other, be free from obstructions and be maintained at a sufficient distance from the mechanical part of the winding device. In addition, the yarn is fed to the winding device in a simple manner immediately after hanging on the suction device, without an additional yarn guiding device. Thereby, threading and feeding of the yarn to the winding device is possible in a very short time, so that a very short process interruption, for example after yarn breakage, can be realized.

  On the one hand, in an advantageous configuration of the invention, the discharge opening is designed so that a long section between the discharge opening and the receiving opening can be bridged, and on the other hand, so as to avoid thread sticking to the machine part. The provided guide tube was adjusted between two positions. At the hanging position of the discharge opening, the yarn is blown out towards the receiving opening for hanging. This position is advantageously chosen such that the best possible flight course is provided for the yarn. After the yarn is taken up by the receiving opening of the suction device and guided between the discharge opening and the receiving opening, the guide tube is moved to the feeding position. In this position, the yarn is advantageously guided for feeding to the winding part. These positions are advantageously arranged in a plane that is vertically, horizontally or arbitrarily oriented.

  In this case, for adjusting the guide tube, it is proposed that the end region of the guide tube having the discharge opening is formed telescopically or elastically. Thereby, pneumatic transport in the guide tube is not adversely affected by the adjustability at the end of the guide tube for positioning of the discharge opening. In this case, the movement is advantageously carried out by a controllable actuator arranged corresponding to the end region of the guide tube.

  A particularly simple variant of the present invention that does not require additional auxiliary means is provided by the advantageous configuration as defined in claim 5. For this purpose, the discharge opening of the guide tube is arranged upstream of the winding location on the inlet side of the winding device, and the receiving opening of the suction device is arranged downstream of the winding location on the outlet side of the winding device. Yes. Thereby, after the yarn is hung from the discharge opening to the receiving opening, the yarn is advantageously guided directly through the winding point. At the winding point, the yarn is taken up by, for example, a catching device and wound around a bobbin.

  In a particularly advantageous configuration of the invention, the yarn is guided in the traversing plane by the movement of the guide tube from the hanging position to the feeding position. In the traverse plane, a yarn guide for traversing the yarn during winding into the package is provided, whereby the yarn guide automatically takes the yarn held on the traverse plane, Guide for delivery and capture.

  In an advantageous configuration, it is proposed to arrange the lubrication device in the feed position downstream of the discharge opening of the guide tube so that the yarn can be threaded through another processing device at the same time. At that time, the yarn is automatically inserted into the lubricating device by the movement of the guide tube from the hanging position to the feeding position.

  The method according to the invention is advantageous in that the yarn can be guided to the winding device with high certainty and reproducibly and can be fed in a short time.

Hereinafter, embodiments of the textured machine according to the present invention will be described in detail with reference to the drawings.
FIG. 1 is a schematic view of a first embodiment of a textured machine according to the present invention.
FIG. 2: Extraction of another embodiment of a textured machine according to the invention.
FIG. 3 is an excerpt from a further embodiment of a textured machine according to the invention.

  FIG. 1 schematically shows the working location of a textured machine according to the invention. The textured machine has a large number of work points, and one thread is textured and wound up at each work point. Thereby, since each work location is configured the same, each process unit of the textured machine will be described below in accordance with the yarn travel path of one work location.

  In the creel 3, the yarn supplying package 1 is fitted on the mandrel 2. The yarn feeding package 1 has a smooth thermoplastic yarn 36. The yarn 36 is pulled out from the yarn supply package 1 through the first delivery mechanism 5 through the head. For this purpose, a yarn guide 4 is arranged downstream of the yarn supply package 1. From the delivery mechanism 5, the thread 36 reaches the textured zone. The textured zone is formed by the textured unit 8, the heating device 6 and the cooling device 7. In this example, the textured processing unit 8 is configured as a provisional device, so that the textured unit 8 is fixed in the heating device 6 and the cooling device 7 rather than the temporary generated in the yarn 36. A turning roller 9 is disposed upstream of the textured unit 8.

  The yarn 36 is pulled out of the textured zone through the second delivery mechanism 10 and conveyed to the post-processing zone. A second heating device 11 is provided in the post-processing zone. A third delivery mechanism 14 is disposed downstream of the heating device 11. The delivery mechanism 14 includes a godet 16 and an idle roller 17 as a godet delivery mechanism.

  The delivery mechanisms 5 and 10 are configured, for example, as “nip-type delivery mechanisms (Klemmlieferwerk)”. In the case of the nip type delivery mechanism, the yarn is guided between a delivery shaft to be driven and a pressure roller applied to the peripheral surface of the delivery shaft. In this case, the delivery mechanisms 5 and 10 can be driven by a collective drive unit or an individual drive unit. However, it is also possible to use a conveyance roller or a godet.

  A winding device 20 having a winding portion is disposed downstream of the delivery mechanism 14. The winding location has a package holder 24 that is pivotably supported. A bobbin 23 is fastened to a free end of the package holder 24. The bobbin 23 is applied to the peripheral surface of the drive roller 22 for winding the package. The driving roller 22 is driven by the driving unit at a substantially constant peripheral speed. A traverse device 21 is provided before the yarn 36 is wound on the package. The traverse device 21 guides the yarn back and forth within the package width. This type of traverse device may have a traverse yarn guide 37 driven by a fold grooved shaft or a traverse yarn guide 37 driven by a belt drive. The traverse yarn guide 37 moves in parallel to the drive roller 22 and defines a traverse plane with the head yarn guide 39 disposed upstream. The head yarn guide 39 is disposed on the support 40 together with a lubrication device 38. In the operating position, the yarn 36 is guided through the lubrication device 38 and the head yarn guide 39 one after the other. In this case, the head yarn guide 39 is disposed downstream of the lubricating device 38 and forms one end of a triangle formed by traversing.

  The textured machine has a threading device for conveying the yarn 36 pneumatically so that the yarn 36 can be fed at the start of the process at the work site. The threading device is substantially formed by the guide tubes 12 and 18. For this purpose, a guide tube 12 having an injector 13 is connected to the outlet of the second heating device 11. Thereby, the suction opening 33 is formed on the inlet side of the heating device 11. Through the suction opening 33, an air flow is sucked when the injector 13 is active.

  The guide tube 12 added to the heating device 11 has a discharge opening 34 at an end portion facing the guide tube 12. The discharge opening 34 is opened on the inlet side of the delivery mechanism 14. A suction opening 28 of the second guide tube 18 is formed on the opposite exit side of the delivery mechanism 14. In this case, the discharge opening 34 of the first guide tube 12 and the suction opening 28 of the second guide tube 18 are located facing each other in one plane. The guide tube 18 is connected to an injector 19. The injector 19 generates an air flow in the guide tube 18, and this air flow is directed in the yarn traveling direction. The guide tube 18 ends just before the winding device 20. A discharge opening 27 is formed in the end section 31 of the guide tube 18. The end section 31 is connected to the other sections of the guide tube 18 by an elastically formed sleeve 32. In order to adjust the position of the discharge opening 27, an actuator 30 is provided. Actuator 30 acts on end section 31 of guide tube 18. The discharge opening 27 provided at the end of the guide tube 18 is positioned opposite the receiving opening 26 of the suction device 25. The sucking device 25 is arranged corresponding to the winding device 20 for picking up and drawing out the yarn during the package exchange process. A lubrication device 38 and a head yarn guide 39 are disposed downstream of the discharge opening 27 provided in the guide tube 18.

  The end region 31 of the guide tube 18 is adjusted by the discharge opening 27 between the upper hanging position and the lower feeding position. In FIG. 1, the guide tube 18 is shown in the feeding position. The hanging position of the guide tube 18 is indicated by a broken line.

  In the illustrated embodiment, the suction device 25 having the receiving opening 26 is arranged on the outlet side of the winding position, downstream of the driving roller 22 as viewed in the yarn traveling direction, and the discharge end 27 of the guide tube 18 is It is arranged upstream of the driving roller 22 when viewed in the yarn traveling direction on the inlet side of the winding portion. The yarn is guided across the winding site. As a result, it is possible to hang and feed the yarn without imposing a burden on the yarn without much entanglement of the yarn. However, it is also possible to arrange the suction device 25 immediately after the traverse device 21 and immediately before the drive roller 22.

  FIG. 1 shows the work location of the illustrated embodiment of the textured machine in a state immediately before the start of the process. In this case, the traveling yarn 36 is already guided through the process units 5, 6, 7, 8, 10, 11, and 14 arranged in series with the yarn. At that time, in the winding device 20, the yarn 36 is received by the sucking device 25 and guided to the waste container.

  In order to feed the yarn 36, the yarn 36 is first guided manually by a suction gun. After the yarn 36 is inserted into the process units 5, 6, 7, 8, 10, the yarn 36 is taken up through the suction opening 33 provided at the inlet of the heating device 11 and discharged by the air flow in the guide tube 12. Guided to opening 34. The yarn 36 discharged from the guide tube 12 is captured by the suction opening 33 of the second guide tube 18 on the opposite side of the delivery mechanism 14. Here, the yarn 36 guided in parallel to the delivery mechanism 14 has already been automatically fed to the godet delivery mechanism by the feeding device 15. The feeding device 15 can be formed of, for example, a turning drive unit and a turnable yarn guide, and winds the yarn around the delivery mechanism 14 a plurality of times.

  After the yarn 36 is taken up by the guide tube 18, the yarn 36 is blown out from the discharge opening 27 by the air flow generated by the injector 19 in the guide tube 18 and taken up by the receiving opening 26 of the suction device 25. For this purpose, the end section 31 of the guide tube 18 is held by the discharge opening 27 at the upper hanging position (illustrated by a broken line). At the position where the discharge opening 27 is hung, the yarn 36 is discharged without any obstacles to the receiving opening 26 located opposite to the suction device 25. After hanging, the thread 36 is guided between the discharge opening 27 and the receiving opening 26 in the guide plane and led out to the thread disposal container via the suction device 25. In order to feed the yarn to the winding position of the winding device 20, the actuator 30 is active to guide the end section 31 of the guide tube 18 with the discharge opening 27 to the lower feeding position. It becomes. In the feeding position, the guide plane defined between the discharge opening 27 and the receiving opening 26 is substantially equal to the traversing plane in which the yarn 36 is guided back and forth during winding into the package. In this state, the yarn is taken up by the traverse yarn guide 37 of the traversing device 21 and taken up by an empty bobbin for capture and winding. This process is started by turning the package holder 24. At that time, the yarn is captured by the traverse yarn guide 37 and a capturing device not described in detail here, and wound on the bobbin 23. Thereby, the process of feeding the yarn 36 at the work site of the textured machine is completed.

  At the time of transition from the hanging position to the feeding position, the thread 36 is simultaneously inserted through the guide tube 18 into the lubrication device 38 and the head thread guide 39, so that the thread 36 is lubricated and wound through the head thread guide 39. Supplied to the take-up section.

  In the case of the textured machine shown in FIG. 1, the injectors 13 and 19 for conveying the yarn pneumatically are shut off during winding. However, in order to support the conveyance of the yarn, the injectors 13 and 19 may not be interrupted during winding. This achieves a particularly low yarn stress when winding the yarn.

  2 and 3 schematically show a partial view of another embodiment of a textured machine according to the present invention. In this case, components having the same function have the same reference numerals. The following description applies to both drawings unless explicitly limited to one drawing.

  Only the process unit provided in the machine frame 45 and immediately before the winding device 20 is shown. In this case, the machine of the textured machine can be operated from two sides facing the machine frame 45, namely the operating side 46 and the doffing side 47. On the doffing side 47 of the machine frame 45, the winding device 20 with a plurality of winding points can be arranged adjacent and overlapping. FIG. 2 and FIG. 3 show the winding location of the work location. From the doffing side 47, the fully wound package of the winding part can be removed and carried out.

  Process units such as textured units, delivery mechanisms and tangling devices can be advantageously arranged on the operating side 46 of the machine frame 45 located oppositely. These process units can be operated by an operator from the operation path. In order to automatically guide the yarn 36 from one machine side 46 to the opposite machine side 47 to the winding site of the winding device 20, each work site is provided with guide tubes 12, 18. It is configured. The guide tubes 12 and 18 enable pneumatic conveyance of the thread 36. For this purpose, the delivery mechanism 10 is arranged on the operation side 46 in the lower region of the machine frame 45. In this case, the delivery mechanism 10 is formed by the godet 16 and the idle roller 17. The godet 16 and the idle roller 17 are wound in multiple numbers by the thread 36. Another delivery mechanism 14 is positioned opposite the delivery mechanism 10 on the facing doffing side 47. The delivery mechanism 14 is also formed by a godet 16 and an idle roller 17. The godet 16 and the idle roller 17 are wound with multiple yarns. A heating device 11 and a guide tube 12 connected to an inlet and an outlet of the heating device 11 are arranged in a yarn traveling path between the delivery mechanism 10 and the delivery mechanism 14. The guide tube 12 is connected to the injector 13. The injector 13 generates an air flow that flows in the yarn traveling direction. At that time, the guide tube 12 forms a suction opening 33 on the inlet side. Opposite to the suction opening 33, a discharge end 34 formed at the end of the guide tube 12 is located. A cutter 31 is provided in a holder 32 in a suction opening 33 provided in an inlet region of the heating device 11. On the doffing side 47, the winding device 20 is disposed above the delivery mechanism 14. The winding device 20 has a traverse device 21, a driving roller 22, and a suction device 25 at a winding location corresponding to the work location, as viewed in the yarn traveling direction. A bobbin or a package 48 is held by a package holder 24 on the peripheral surface of the drive roller 22.

  A guide tube 18 is arranged in the machine frame 45 to guide the yarn from the delivery mechanism 14 to the winding device 20. The guide tube 18 has a suction opening 28. The suction opening 28 is arranged on the side of the delivery mechanism 14 that faces the discharge opening 34 of the guide tube 12. At that time, the discharge opening 34 and the suction opening 28 are positioned to face each other at a certain angle. The guide tube 18 has a discharge opening 27 at the other end. The discharge opening 27 faces the traverse device 21.

  Between the discharge opening 34 of the guide tube 12 and the suction opening 28 of the guide tube 18, a guide plate 44 made of a thin metal plate is disposed at a distance from the delivery mechanism 14 in the discharge direction and the suction direction. The guide plate 44 has a curvature that causes a change in direction of the air flow flowing out from the discharge opening 34.

  Between the discharge opening 27 of the guide tube 18 and the traverse device 21, a lubrication device 38 and a head yarn guide 39 are arranged in the yarn traveling path. For example, the lubricating device 38 may be immersed in an oil tank and have a roller for guiding the yarn on the surface thereof.

  The guide tube 18 has a movable end region 31, and the end region 31 is connected to a fixedly arranged portion of the guide tube 18 via a telescopic guide 35. A discharge opening 27 is formed in the movable end region 31 of the guide tube 18. The discharge opening 27 is directed towards the receiving opening 26 of the suction device 25. The actuator 30 acts on the end region 31 of the guide tube 18. The actuator 30 can guide the movable end region 31 of the guide tube 18 to the hanging position and the feeding position.

  In order to feed the yarn for the first time, and in order to hang the yarn 36 from the operation side 46 to the winding device 20 provided on the doffing side 47, the yarn 36 is then pulled by a manually operated suction gun. Then, it is guided to the suction opening 33 provided in the inlet region of the heating device 11. The injector 13 of the guide tube 12 and the injector 19 of the guide tube 18 are activated. The yarn 36 is sucked into the suction opening 33 after being cut by the cutter 31 and blown out from the discharge opening 34. Thereafter, the loose yarn is turned toward the suction opening 28 by the guide plate 44. After the guide tube 18 pulls the yarn through the suction opening 28, the yarn 36 is discharged through the discharge opening 27 toward the receiving opening 26 located opposite to the suction device 25. This situation is illustrated in FIG. In this case, the end section 31 of the guide tube 18 with the discharge opening 27 is in the hanging position. After the thread 36 is taken up by the receiving opening 26 of the suction device 25, the thread hanging is completed.

  In order to feed the yarn 36 to the winding position of the winding device 20, the actuator 31 is activated again so that the discharge opening 27 can be guided to the feeding position. FIG. 3 shows an operating state in which the end section 31 of the guide tube 18 is held at the feeding position. At that time, the yarn 36 is already wound on the package. At the feeding position, the yarn is guided in the traverse plane and is ready for take-up by the traverse yarn guide 37. The winding process at the work site can be started. FIG. 3 shows the work location during the textured process. As a result, the yarn 36 is wound on the package 48.

  The embodiment shown in FIGS. 1, 2 and 3 of the textured machine according to the present invention is exemplary in terms of the arrangement and configuration of the process units. Important for the automatic operation of the textured machine is the simple and rapid initial feeding of the yarn in the winding device. Again, the adjustability of the discharge opening of the guide tube at multiple positions is exemplary. In other words, these positions may be formed in a horizontal plane if the machine components are appropriately configured. What is important here is that during automatic feeding of the yarn, the discharge end of the guide tube and the receiving opening of the suction device are for hanging the yarn at one position and for feeding the yarn at the other position. Therefore, they are held relative to each other.
