Description

[0001] The invention relates to a mouth application device for automatically applying a synthetic thread in a mouth of a heating device of a texturing device for texturing the synthetic thread into a textured thread.

[0002] Texturing devices and the associated application devices for applying synthetic threads to a heating device are known from the general state of the art.

[0003] DE 10 2004 007 074 A1 discloses a method for applying a yarn in an associated false twist texturing machine. At the beginning of the process, the synthetic yarn to be textured is applied from a supply spool via take-off feeders to a heating device, a cooling device, a false twist device, and a winding device. For feeding the synthetic yarn to the heating device, a feeding device is provided. This device has a linear guide along which a carriage is movable, via which the synthetic yarn is fed to the heating device.

[0004] WO 00 22 211 A1 discloses a texturing machine for texturing a plurality of thermoplastic threads, each at a processing station. For this purpose, the threads are guided and conveyed through several feeders in the processing station. One of the feeders is attached to a movable carriage. For this purpose, the carriage is guided along a guide rail and is moved between an operating position and an operating position by means of a linear drive. The carriage makes it possible to guide the thread to a heating device.

[0005] The problem with both of the application and guiding devices known from the respective documents is that the transfer of the thread via the respective application device, particularly to the opening of the heating device, is prone to errors, and can lead to incorrect and / or faulty positioning of the thread towards the opening of the heating device. Furthermore, the timing of the transfer cannot be adjusted.

[0006] The object of the invention is therefore to provide a mouth insertion device for automatically placing a synthetic thread into a mouth of a heating device, with which it is possible to carry out a safe and time-determined positioning of the thread on the heating device.

[0007] Furthermore, it is an object of the invention to provide a corresponding texturing device with the associated mouth application device according to the invention.

[0008] The object with regard to the muzzle insertion device is achieved according to the invention with a muzzle insertion device having the features according to claim 1.

[0009] According to one aspect of the invention, a mouth application device is provided for automatically applying a synthetic thread in a mouth of a heating device from a texturing device for texturing the synthetic thread into a textured thread, comprising an application part for applying the synthetic thread into the mouth and a triggering part for triggering the insertion of the insertion part, wherein by engaging the application part with the triggering part the synthetic thread can be laid into the mouth of the heating device.

[0010] The nozzle placement device essentially comprises two parts: a movable placement part and a fixedly positioned trigger part associated with the placement part. The trigger part acts on the placement part in such a way that, by engaging the placement part with the trigger part, precise positioning and laying of the synthetic thread into a nozzle of the heating device can take place. Furthermore, it is possible to set a predetermined time delay during the transfer.

[0011] According to one embodiment of the mouth application device, the application part has a thread guide for gripping the synthetic thread, wherein the thread guide is mounted on a support carriage and can be moved by means of the support carriage between a starting position in which the thread is in engagement with the thread guide and a placement position in which the thread can be inserted into the mouth of the heating device.

[0012] The movable or movable feeder part, which guides the thread to the trigger part or the opening of the heating device, is a movable support carriage that can be moved at least between a starting position and a feeder position. In the feeder position, the trigger part interacts with the feeder part in such a way that the thread is securely fed into the opening of the heating device.

[0013] The time at which the thread is laid into the mouth can be adjusted, for example, by changing the start and application position.

[0014] The mooring position is adjacent to the opening of the heating device.

[0015] According to a further embodiment of the muzzle application device, the application part has a clamping device for holding the thread, wherein the holding of the thread at the application position is releasable.

[0016] The clamping device can be used to secure a free end section of the synthetic thread wound on a supply spool to the attachment part. Clamping can be performed at the level of the supply spools by clamping the free end section to the attachment part using the clamping device.

[0017] The clamping device has a release mechanism that can be triggered at the application position using the release part. By triggering the clamp release mechanism, the clamp is released, and the free thread end section can be placed into the opening of the heating device.

[0018] The clamping device can have two clamping claws pre-tensioned against each other.

[0019] According to another embodiment of the muzzle application device, the application part has a rotatable thread guide for gripping the synthetic thread, wherein the thread guide is rotatably mounted in the support carriage, wherein the rotation of the thread guide can be effected by bringing it into engagement with the trigger part.

[0020] A rotatable thread guide is preferably provided if a thread loop is formed at the thread guide and the free thread end section is guided back to the level of the supply spools. The thread guide is provided on the attachment part. The thread can be guided to the opening with the thread guide.

[0021] According to a further embodiment of the muzzle positioning device, the thread guide is coupled to a rotary latch by means of a pivoting shaft in such a way that the thread guide is pivoted by pivoting the rotary latch.

[0022] The thread guide is coupled to a pivoting shaft with a rotary latch in a rotationally fixed manner, so that the thread guide is also pivoted by pivoting the rotary latch, thus ensuring secure positioning of the thread in the mouth.

[0023] According to a further embodiment of the mouth application device, the thread guide for receiving the synthetic thread has a receiving groove and / or a thread catching projection, wherein the receiving groove and / or the thread catching projection are / is rotatable.

[0024] For secure positioning, the thread guide is provided with a receiving groove into which the synthetic thread can be inserted. To ensure secure guidance and positioning of the synthetic thread, the receiving groove can be provided with a thread catching projection on the side, which allows for improved holding and guiding of the thread. The thread catching projection is designed to hinder and / or prevent the thread from jumping out of the receiving groove.

[0025] Both the receiving groove and the thread catching projection are rotatably mounted individually or together in the muzzle positioning device or the associated support system of the muzzle positioning device.

[0026] According to another embodiment of the muzzle application device, the trigger part is fixedly positioned relative to the application part and has a stop projection and a stop carrier to which the stop projection is fastened.

[0027] The trigger part is positioned and arranged on the stop projection at a predetermined position adjacent to the heating device, so that the triggering and application process of the synthetic thread in the heating device can take place at the correct position and at the correct time when the application part is moved toward the heating device. By changing the position of the trigger part, the time at which the thread is released at the application position can be controlled.

[0028] For this purpose, the trigger part has a stationary positioned stop carrier which has a trigger part in the form of a stop projection.

[0029] The stop projection can, for example, be a bolt which interacts with the application part in such a way that precise positioning of the synthetic thread in the heating device is possible.

[0030] According to a further embodiment of the muzzle positioning device, the rotary bolt is mounted on the pivot shaft in a pre-tensioned manner in a rotary bolt carrier, so that the rotary bolt is pre-tensioned away from the rotary bolt carrier.

[0031] The rotary latch is pivotally mounted on a rotary latch support and held in a pre-tensioned position. The pre-tension can be achieved, for example, with a suitable torsion spring arranged around the pivot shaft and positioning the rotary latch away from the rotary latch support. The pre-tension positions the rotary latch so that, in the application position, the rotary latch can be easily and securely engaged with the trigger part or the stop projection of the trigger part, thus enabling the secure insertion of the synthetic thread into the opening of the heating device.

[0032] According to a further embodiment of the muzzle application device, a cutting knife is positioned at the position of the rotary latch carrier adjacent to the muzzle of the heating device.

[0033] The cutting blade is used to separate the synthetic thread during the application process at the heating device, allowing a free end to be fed into the heating device. The thread is fed via the linear guide and the associated carriages over rollers, with the thread being guided on both sides with a predetermined tension.

[0034] In order for a free end to be inserted into the heating device, the thread loop must be cut at the attachment position.

[0035] According to another embodiment of the muzzle application device, the muzzle application device is attached to a placement arm for laying the synthetic thread from a supply spool to the heating device by means of a mounting web at a distance therefrom.

[0036] The mounting bracket also allows for retrofitting the muzzle positioning device to existing positioning arms. Furthermore, a suitably mounted positioning arm allows for easier maintenance and repair of the muzzle positioning device.

[0037] According to a further embodiment of the mouth application device, the application arm has a deflection roller at a first end section for deflecting the thread towards a conveyor roller rotatably mounted at the opposite second end section for feeding the thread towards the mouth application device, wherein the deflection roller and the conveyor roller are each mounted in a first mounting receptacle and a second mounting receptacle on the application arm

[0038] The deflection roller or conveyor roller on the feed arm serves to ensure that the loop formed by the synthetic thread can be safely guided to the position near the outlet opening of the heating device. To ensure safe and even guidance of the synthetic thread, the conveyor roller is rotatably mounted and can be set in rotation by the thread inserted in the conveyor roller.

[0039] According to a further embodiment of the muzzle positioning device, the first mounting receptacle for pivoting and moving the positioning part cooperates with a pivoting link which is positioned at the positioning position.

[0040] The swivel link, preferably an angled sheet metal, allows guidance and swiveling of the mounting holder, which, when the application arm together with the mounting holder are brought into engagement with the swivel link, the swivel arm is swiveled into the predetermined application position.

[0041] In addition, the swivel link ensures that the mooring arm and the mooring part attached to it are moved and swiveled to the exact mooring position.

[0042] The object is achieved with regard to the texturing device with a texturing device having the features according to claim 13.

[0043] According to one aspect of the invention, a texturing device is provided for false twist texturing a plurality of synthetic threads which are provided on supply spools, wherein in the texturing device the synthetic thread is textured into a textured thread, comprising a first, second and / or third delivery mechanism for feeding and stretching the synthetic thread, a first heating device for preheating the synthetic thread, a cooling device for tempering the synthetic thread, a false twist unit for texturing the synthetic thread and a set heating device for fixing the texturing, wherein a mouth application device according to at least one of the preceding embodiments is provided for feeding the synthetic thread to a mouth of the heating device.

[0044] The mouth application device according to the invention is explained in more detail below using some embodiments of the mouth application device according to the invention together with the associated texturing device with reference to the attached figures.

[0045] They represent: Fig. 1 schematically shows a view of a texturing device with its essential devices with a mouth application device according to the invention, Fig. 2 a schematic detailed view of the mouth application device according to the invention together with a suction device for sucking in the synthetic threads to be processed, Fig. 3 to Fig. 5 different position views and detail views according to the Fig. 1 detailed view of the mouth application device together with an associated application carriage between a start position, intermediate position or an application position for applying the synthetic thread in a mouth of a heating device

[0046] Fig. 1 schematically shows a texturing device 100, wherein a mouth application device 30 according to the invention is provided at a predetermined position for applying the synthetic thread F in a heating device 18, in particular at its mouth 41 in a application position A for more precise and better positioning.

[0047] The schematic representation of the texturing device 100 is simplified and shown schematically for better understanding. The texturing device 100 can also be configured differently.

[0048] The texturing device 100 has several devices and means for texturing a synthetic thread F, which is provided wound on supply spools 7.

[0049] The supply spools 7 are mounted in a creel frame 2 for unwinding the synthetic thread F. A first, second and third conveyor system 11, 12 and 13 are provided for feeding and stretching the synthetic thread F.

[0050] After the first conveyor 11, a linear guide 8 is provided, in which a feed carriage 60 can be moved from the position of the creel frame 2 to the feed position A at the heating device 18 with inserted synthetic thread F. The linear guide 8 is supported via a feed frame 4, for example, on the creel frame 2.

[0051] Above the gate frame 2 adjacent to the application position A, the mouth application device 30 is arranged, which can be moved by means of the application carriage 60 together with the synthetic thread F to the application position A.

[0052] At the application position A, the synthetic thread F is brought into a first heating device 18 for heating and preheating the synthetic thread, so that a corresponding texturing of the synthetic thread F into a textured thread T is possible.

[0053] Adjacent to the first heating device 18, a cooling device 19 is provided which tempers the synthetic thread F to a predetermined temperature in order to prevent overheating or excessive heat input to the synthetic thread F.

[0054] The yarn F is then brought to a false twist unit 20 via deflection rollers 14. For this purpose, rotating bands, belts, or discs can be provided in the false twist unit 20, which produce a texturing on the synthetic yarn F by applying a torque.

[0055] The synthetic thread F is then guided via a second delivery system 12 to a set heating device 22.

[0056] In the set heating device 22, the texturing is fixed to the synthetic thread F. Then, the textured thread T is further fed via a third delivery device 13 and associated deflection rollers 14 to a winding device 9.

[0057] In the texturing device 100, a heating device 18, delivery mechanisms 11, 12, 13, a false twist unit 20, a cooling device 19, a winding device 9 and a mouth application device 30 are provided for each thread F.

[0058] The winding devices 9 can, for example, have a friction roller 24 for conveying the textured thread T, a winding spool 25 onto which the textured thread T is wound, and a traversing device 26 with which the textured thread T can be wound, for example with a cross-wound bobbin winding, into a winding spool 25.

[0059] In other embodiments of the texturing device 100, the mouth application device 30 can also be provided at other positions, for example for applying the thread to a mouth of a set heating device 22, a cooling device 19 and / or a delivery mechanism 11, 12, 13.

[0060] Fig. 2 shows a schematic detailed view of the essential components of the mouth application device 30 together with a suction device 40, via which the synthetic thread F is sucked and guided towards the first heating device 18.

[0061] As from Fig. As can be seen from Figure 2, the muzzle application device 30 has an application part 301 and a trigger part 302.

[0062] The attachment part 301 can be mounted and attached to the attachment carriage 60 via a mounting web 34.

[0063] It is also possible in other embodiments that the mounting web 34 is not mounted by a screw connection, but directly on the application carriage 60 in another way, such as by welded connections and / or by rivets.

[0064] The attachment part 301 has a support carriage 39, which is mounted to the mounting bar 34 by means of a screw connection. The mounting bar 34 is mounted to the attachment carriage 60 with a mounting bracket 360.

[0065] The support carriage 39 further comprises a thread guide 36 which is rotatably mounted on the support carriage 39 so that the synthetic thread F can be guided towards the mouth 41 of the first heating device 18.

[0066] According to an embodiment not shown, the application part 301 has a clamping device for holding the thread. The clamping device is designed to hold the thread F, and the clamping force can be released at the release part 302, so that the thread is released at the application position A and can be laid into the opening 41.

[0067] With the clamping device, a free thread end portion of the synthetic thread F, which is wound on a supply spool 7, can be fastened to the application part 301. The clamping can be carried out at the level of the supply spools 7 by clamping the free thread end portion to the application part 301 by means of the clamping device.

[0068] The clamping device has a release mechanism that can be triggered at the application position A by means of the release part 302. When the clamp release mechanism is triggered, the clamp is released and the free thread end section can be placed in the mouth 41 of the heating device 18.

[0069] The clamping device can have two clamping claws pre-tensioned against each other.

[0070] The heating device 18 further comprises, as in Fig. 2, a suction device 40 which is supplied with suction air via a compressed air connection 46 so that the thread can be guided towards the heating device 18.

[0071] At the opening 41 of the heating device 18, there is a compressed air connection 45, through which intake air can be supplied for sucking the thread F into the opening 41. The supply line for supplying the intake air is not shown or illustrated.

[0072] Furthermore, a cutting blade 42 is provided near the mouth 41, which is designed to form a free thread end that can be sucked into the mouth 41 when the thread F is to be fed as a thread loop FS. The cutting blade 42 cuts off a thread loop FS fed by the mouth application device 30 when the synthetic thread F has been brought into the depositing position A by the mouth application device 30.

[0073] In the Fig. In the embodiment of the muzzle application device 30 shown in Figure 2, the thread guide 36 has a carrying carriage 39 on which a rotary latch carrier 34 is rotatably mounted.

[0074] The rotary latch carrier 34 has, on the one hand, a receiving groove 35 formed with a thread catching projection 37 for receiving the synthetic thread F and, on the other hand, a rotary latch 33 which is connected in a rotationally fixed manner to the thread guide 36 via a pivot shaft 38, so that the synthetic thread F can be guided exactly into the mouth 41 when the rotary latch 33 is triggered.

[0075] The muzzle application device 30 has a trigger part 302 for triggering the application part 301, which is positioned stationary adjacent to the muzzle 41.

[0076] The trigger part 301 has a stop projection 31 that protrudes from a stop support 32. The stop projection 31 can be, for example, a stud bolt and / or pin.

[0077] With the length of the rotary latch 33 and the distance of the engagement point of the rotary latch 33 with the stop projection 31, for example, the time at which the thread F is released to the mouth 41 can be determined.

[0078] The time of release can also be determined by the distance of the trigger part 301 relative to the application part 301.

[0079] Both options can also be combined.

[0080] In the Fig. 3, Fig. 4 and Fig. 5 shows the application of the synthetic thread F in the mouth 41 of the heating device 18 by means of the mouth application device 30 from a starting position S, intermediate position Z or application position A in succession.

[0081] The muzzle device 30, as shown for example in Fig. 3, is attached to the application carriage 60 via the mounting piece 360. In Fig. 3 shows the starting position S of the application process in the heating device 18.

[0082] The feed carriage 18 is moved via the guide rail 50 with a linear guide 8 to the feed position A, in which a pivoting link 53 for actuating the feed carriage 60 is fixed in place.

[0083] The swivel link 53 is mounted on the guide rail 50 via a link assembly 51. This can be, for example, a screw connection, as in Fig. 3. However, other mounting methods are also possible, such as riveted and / or welded connections.

[0084] As further in the starting position in Fig. 3, the application carriage 60 is not yet engaged with the pivoting link 53, but is spaced apart from it.

[0085] The synthetic thread F forms a loop FS and is wound around the conveyor roller 61 at one end portion of the application carriage 60 and the thread guide 34 of the mouth application device 30.

[0086] In Fig. 4, the feed carriage 60 is engaged with the pivoting link 53 at least on the conveyor roller 61 by means of a second mounting receptacle 64. The conveyor roller is rotatably mounted in the mounting receptacle. The second mounting receptacle 64 also causes the pivoting of the feed carriage 60 when the second mounting receptacle 64 engages with the pivoting link 53, as shown in Fig. 4 shown.

[0087] The deflection roller 63 arranged on the second end section of the feed carriage 60 at the opposite end to the first end section with the conveyor roller 61 is mounted in a mounting receptacle 63 on the feed carriage or on the feed arm 65.

[0088] As further stated Fig. 4, the loop FS formed by the synthetic thread F - shown with a dashed line - runs over the deflection roller 62 to the conveyor roller 61 and the thread guide 36 and a thread overrun 10, so that the synthetic thread F has sufficient tension and is collected, for example, in a waste container until the synthetic thread F has been laid in the mouth 41.

[0089] Fig. 5 shows the application position A of the thread F in the mouth 41 of the heating device 18.

[0090] Here, the thread F was severed by the thread cutter 42 and sucked up by the suction device 40 and brought into the heating device 18 and into the thread guide line 43. In the thread guide line 18, the thread F is heated by the heating device 18.
