Hang Method, in particular, for taking up melt-spun yarn in a take-up winding device Hang It concerns the method. [Background technology]

[0002] In the production of synthetic yarns, molten polymer is fed at high pressure by a spinning pump to a spinning nozzle and extruded in multiple thin filament strands. After extrusion and cooling, the filament strands are brought together to form a single yarn. The multiple yarns thus produced are wound in parallel on a so-called winder to form a package.

[0003] This type of winding machine, also called take-up winding device, has for winding a so-called winding spindle with a chuck and a clamping jacket with a clamping device for supporting and attaching the winding tube arranged on the circumference of the chuck. One winding tube can be arranged on the winding spindle for each yarn to be wound. The winding spindle can be mounted on one side and can be arranged to protrude above the spindle support, so that the package wound around the circumference of the winding spindle can be removed from the free end of the winding spindle after completion. The removal of the package is also called doffing.

Hang The aim was to define the method. [Means for solving the problem]

[0007] thread HangingWith regard to the device, this object is achieved by the subject matter of claim 1 or claim 16, respectively. A take-up winding device is defined in claim 17, which winds the melt-spun yarn. Hang The method is defined in claim 18. Advantageous design embodiments are the subject of the respective dependent claims and are explained below.

[0008] Melt spun yarn Hang Therefore, especially in the take-up winding device for melt-spun yarn, Hang The yarn according to the invention for Hanging The apparatus includes a suction unit for suctioning at least one melt spun yarn, a positioning device for guiding and moving the suction unit, and a yarn movably guided by the positioning device. Hanging and an auxiliary device. Here, the suction unit and the suture Hanging The auxiliary device can be placed in different functional positions by a movement guided by a positioning device, Hanging The auxiliary device is a thread Hanging It is arranged to be movable relative to the suction unit in order to perform the auxiliary action.

[0009] As a result of the positioning device provided by the present invention, the suction unit and the thread Hanging The auxiliary device is a take-up winding device for winding each melt-spun yarn. Hanging With only a little effort from the operator, the yarn can be moved to the different functional positions required for Hanging A thread movably arranged relative to the suction unit for performing an auxiliary action Hanging The auxiliary device can provide additional flexibility for guiding or positioning, respectively, the melt-spun yarn aspirated by the suction unit, resulting in a significant or only minor overall reduction in the operator's manual effort. Hang This can reduce the risk of melt spun yarns becoming tangled or breaking. Hanging is advantageously carried out for the yarn according to the invention. HangingThe process can be fully automated or at least partially automated by the device. Hanging The reliability of the process can be increased.

[0010] thread Hanging According to an advantageous design embodiment of the device, the thread Hanging The auxiliary device is a thread Hanging The yarn may be configured as a roller. Hanging The rollers require little effort in terms of construction and at the same time make it possible to reliably capture each melt-spun yarn and guide it to the desired position in the take-up winding device.

[0011] Further preferably, the melt spun yarn sucked by the suction unit is provided with a yarn guide and / or positioning device. Hanging The auxiliary device can contact the thread. Hanging Assistive devices or threads Hanging Yarn configured as roller Hanging Each of the auxiliary devices can contact the melt-spun yarn while it is being sucked by the suction unit and then perform the respective desired positioning. Hanging This allows for a particularly advantageous interaction between the auxiliary devices, so that the yarn Hanging Automated operations in the process can be further improved.

[0012] According to another advantageous design embodiment, the suction unit and / or the thread Hanging The auxiliary device can be positioned by a movement guided by the positioning device at the yarn catching position, where the at least one melt spun yarn can be received and / or sucked by the yarn injector and / or the spinning nozzle. In particular, at the yarn catching position, the at least one melt spun yarn can be initially received and / or sucked by the yarn injector and / or the spinning nozzle. Thus, at the yarn catching position, the melt spun yarn exiting the spinning nozzle and / or the yarn injector can be initially sucked and thus received by the suction unit.

[0013] In this state of the melt spun yarn, where the melt spun yarn is sucked and received by the suction unit, the suction unit can be preferably moved to at least one further functional position, during which the sucked and thus received state of the melt spun yarn is maintained. As a result of the ability to position the suction unit at the yarn capture position, the melt spun yarn can be sucked and thus received by the suction unit. Hanging The process can advantageously be started without any manual intervention, in particular by an operator.

[0014] According to another advantageous design embodiment, the suction unit and / or the thread Hanging The auxiliary device can be placed by a movement guided by a positioning device into a yarn cutting position, in which at least one melt-spun yarn can be severed and / or cut by a yarn cutting device. The yarn cutting device can advantageously be a yarn cutting device of a take-up winding device and / or a so-called gathering / chopping device. Using such a gathering / chopping device, the melt-spun yarn can be cut or severed, respectively, with high reliability and precision and at the same time with low construction-related efforts. The yarn cutting position can therefore be a chopper yarn cutting device, in which at least one melt-spun yarn can be severed and / or cut by a gathering / chopping device. Hanging It may be a position.

[0015] Cutting and / or severing of melt spun yarns can occur, for example, by Hanging During the winding process, it may be necessary to complete and / or interrupt the winding procedure if undesirable defective winding or entanglement of the melt spun yarn occurs. Hanging The process can be resumed after the melt spun yarn has been cut or severed. As a result of the suction unit being able to be positioned at the yarn cutting position, the cutting or severing of the melt spun yarn can be performed with only low effort and in particular without any manual intervention of the operator.

[0016] According to another preferred design embodiment, the suction unit and / or the thread Hanging The auxiliary device is moved by a guided movement of the positioning device. Hanging Position the draft unit to thread Hanging At the position, at least one melt spun yarn is drawn into a draft unit, particularly a draft unit having multiple godets. Hang In such a draft unit, for example, the melt-spun yarn can be pre-drawn or pre-oriented, and then wound up as a pre-drawn or pre-oriented yarn (POY-pre-oriented yarn). Hanging As a result of the possibility of placing the yarn in a position, pre-drawing or pre-orienting of the melt-spun yarn can be carried out prior to winding with only minor effort, in particular without any manual intervention of the operator.

[0017] More preferably, the suction unit and / or the thread Hanging The auxiliary device can be positioned by a movement guided by the positioning device at a yarn distribution position, in which at least one melt spun yarn can be positioned along the yarn distribution direction by the yarn distribution device and / or can be brought into contact with the yarn distribution device for positioning in the yarn distribution direction. The yarn distribution position is particularly advantageously located at a gathering roller yarn Hanging The position may be a gathering roller yarn Hanging At the position, at least one melt spun yarn is gathered at a gathering roller. Hang The conveying member may be movable and / or may be in contact with a movably disposed gathering roller.

[0018] In particular, the gathering roller yarn Hanging In the position, the melt-spun yarns are collected on one gathering roller in each case. HangIn each case, the yarn distribution device, in particular the yarn distribution device of the winding device, can be advantageously configured as a gathering roller device with multiple gathering rollers, and / or can be configured and / or arranged to contact one melt spun yarn in each case.

[0019] In other words, the melt-spun yarn is gathered at such a gathering roller. Hang The suction units can be arranged at the yarn distribution positions, or can be brought into contact with such gathering rollers, and then positioned in the yarn distribution direction by the respective gathering rollers, or can be pre-aligned along the longitudinal direction of the winding spindle at each desired yarn position. As a result of the suction units being able to be arranged at the yarn distribution positions, the positioning of the melt spun yarn in the yarn distribution direction before winding can be performed by the yarn distribution device with only low effort, in particular without any manual intervention of the operator, or at least with reduced operator effort.

[0020] More preferably, the suction unit and / or the thread Hanging The auxiliary device can be placed in a longitudinal alignment position by a movement guided by a positioning device, in which at least one melt spun yarn can be aligned in the longitudinal direction of the winding spindle, in particular by the longitudinal alignment device, and / or in the longitudinal alignment device Hang The longitudinal alignment position can be, in particular, a so-called lower transition unit threading position and / or a longitudinal alignment device can be threaded into the longitudinal alignment device. The longitudinal alignment device can preferably be configured in the form of a so-called lower transition unit. Hanging Position (LCU thread Hanging position).

[0021] The longitudinal alignment device or the lower transition unit of the take-up winding device can be positioned below or approximately at the height level of the winding spindle positioned at the winding position, and can guide a plurality of melt spun yarns at defined positions spaced apart from one another along the longitudinal direction of the winding spindle, or can move the melt spun yarns to each of the positions spaced apart from one another.

[0022] The melt spun yarns, which are captured, moved to a predetermined position and / or guided by the longitudinal alignment device or the lower transfer unit, respectively, can in each case be fed to a winding tube arranged on a winding spindle and thus wound up on the respective winding spindle. To guide or move the melt spun yarns, they can be threaded into the longitudinal alignment device or the lower transfer unit at a specifically defined receiving portion and / or by means of a locking hook. To thread the melt spun yarns into the longitudinal alignment device or the lower transfer unit, the longitudinal alignment device or the lower transfer unit can be displaced or moved to an open position or a threading position and / or a gathering position. Once the melt spun yarns have been threaded or captured, the longitudinal alignment device or the lower transfer unit, respectively, can be displaced or moved to a closed position or a guide position and / or a distribution position.

[0023] As a result of the suction unit being able to be arranged at the longitudinal alignment position, the longitudinal alignment of the melt spun yarn on the winding spindle and / or the longitudinal alignment device or the yarn on the lower transition unit can be improved. Hanging and / or threading, respectively, before winding can be performed with only low effort, in particular without any manual intervention of the operator or at least with reduced operator effort.

[0024] More preferably, the suction unit and / or the thread HangingThe auxiliary device can be positioned at the winding spindle position by a movement guided by the positioning device, in which at least one melt spun yarn is wound on the winding spindle, in particular on a winding tube arranged on the winding spindle.

Hang or can be captured by the movement of each winding spindle and the winding tubes arranged on each winding spindle, caused by the spindle turret, and the actual winding procedure can be started.

[0027] As a result of the possibility of arranging the suction unit at the winding spindle position, the yarn of the melt spun yarn on the winding spindle or on the winding tube arranged on the winding spindle can be spun. Hanging can be performed with only low effort, in particular without any manual intervention by an operator or at least with reduced operator effort.

[0028] According to another preferred design embodiment, the take-up spindle position of the suction unit may correspond to the longitudinal alignment position of the suction unit.

[0029] Particularly preferably, the yarn proceeds from the functional position determined by the positioning device. Hanging The auxiliary device is a suture unit for sucking the suture.

[0038] According to a further preferred embodiment, a suction unit and / or a thread can be determined by the positioning device. Hanging At least some of the functional positions of the auxiliary devices can be arranged so as to be distributed vertically. Thus, the suction units and / or the sutures can be arranged so as to be distributed vertically. Hanging The auxiliary devices can be arranged by the positioning device in successively vertically distributed functional positions along the guide rail. The vertical distribution can particularly advantageously replace or mimic the manual vertical movement of the suction unit, respectively. Furthermore, the vertical movement sequence is suitable for the transfer of the melt-spun yarn from the guide, spinning nozzle or yarn injector, respectively, to a winding spindle arranged vertically below, capable of carrying out the winding process.

[0039] More preferably, the functional positions can be determined in a predetermined sequence by the positioning device. The functional positions can be particularly preferably determined by the positioning device in the form of a yarn catch position, a yarn cutting position, a draft unit yarn position, a Hanging The positions may be determined in a predetermined order: position, yarn distribution position, longitudinal alignment position and take-up spindle position.

[0040] This type of predetermined sequence and / or vertically distributed arrangement of the functional positions allows the suction units and / or the threads to be Hanging The auxiliary devices are moved by the positioning device, so that the yarn is moved in a predetermined process sequence. Hanging Thus, each individual step can be performed in sequence for each vertically successive functional position.

[0041] According to a further preferred embodiment, a suction unit and / or a thread can be determined by the positioning device. Hanging At least two functional positions of the auxiliary device can be arranged offset from one another in the horizontal direction. In particular, the positioning device can determine a yarn cutting position and / or a draft unit yarn cutting position can be determined by the positioning device. Hanging The position can be arranged to be horizontally offset with respect to at least one other functional position.

The yarn distribution device 118 can be configured as a gathering roller device and / or can have a plurality of gathering rollers 122. Each gathering roller 122 can be movably arranged to contact the melt spun yarn 102. At least some of the gathering rollers 122 can be arranged to be distributed in the x-direction, respectively, so as to contact or individually capture one melt spun yarn 102 in each case. Additionally, the yarn distribution position at each gathering roller 122 can be arranged to be distributed in the x-direction, respectively, so as to contact or individually capture one melt spun yarn 102 in each case. Hanging Positioning of each melt spun yarn 102 for this purpose can be accomplished by movement with the longitudinal axis 20 configured as a transverse axis.

[0097] Figure 8 shows the retracted state of the yarn distribution device 118, while Figure 9 shows the deployed state of the yarn distribution device 118. The yarn portion 102b, shown in dashed lines in Figure 6, can be contacted by the yarn distribution device 118 and, depending on the contacting gathering roller 122, can be moved to a position offset in the yarn distribution direction 120, as shown in Figure 9 as well. The yarn distribution direction 120 can extend in particular in the z-direction.

[0098] The suction unit 14, by the movement guided by the positioning device 12, can be further placed in a longitudinal alignment position shown in FIG. 10, in which the at least one melt spun yarn 102 can be aligned in the longitudinal direction of the take-up spindle 104, in particular by the longitudinal alignment device. The at least one melt spun yarn 102 can be aligned in the longitudinal direction of the take-up spindle 104, in the longitudinal alignment position, preferably in the lower transition unit 124. Hanging and / or may be threaded into the lower transition unit 124.

[0099] The longitudinal alignment device may be in the form of, for example, a lower transfer unit 124. The melt spun yarn 102 is transferred to the lower transfer unit 124 in a yarn Hanging The yarn can be aligned in the longitudinal direction of the winding spindle 104 by being threaded and / or threaded therein, which in this case corresponds in particular to the yarn distribution direction 120 and / or the z-direction.

[0100] For this purpose, the lower transition unit 124 may comprise a number of locking hooks 126, which may be defined to capture in each case one melt-spun yarn 102 and, in the captured state, may effect longitudinal alignment of each melt-spun yarn 102. For this purpose, the locking hooks 126 are arranged movably along the longitudinal direction of the winding spindle 104 or along the z-direction, respectively, with FIG. 9 showing the collective position of the locking hooks 126 and FIG. 10 showing the distributed position of the locking hooks 126.

[0101] Thus, the lower transition unit 124, corresponding to the yarn distribution device 118, can perform longitudinal distribution of the melt-spun individual yarns 102 along the longitudinal direction of the winding spindle 104 or along the z-direction, respectively.

[0102] 10 shows suction unit 14 in a longitudinally aligned position where yarn portions of melt spun yarn 102, shown by dashed lines, can be captured and longitudinally distributed by lower transfer unit 124, or generally by a longitudinal alignment device, respectively. The profile of longitudinally distributed melt spun yarn 102 is shown by solid lines in FIG.

[0103] The threading of the melt-spun yarn 102 into the longitudinal alignment device or into the lower transfer unit 124, respectively, is particularly advantageously carried out by Hanging This can be achieved by the auxiliary device 16. HangingAs a result of the auxiliary device 16, the melt spun yarn 102 proceeding from the longitudinal alignment position can be moved along the longitudinal direction or z-direction, respectively, of the winding spindle 104, thus facilitating threading or capture by the locking hook 126 before the actual longitudinal alignment is performed by the longitudinal alignment device or into the lower transfer unit 124, respectively.

[0104] Finally, the suction unit 14, by a movement guided by the positioning device 12, is adapted to wind at least one melt spun yarn 102 onto a winding spindle 104 or onto a winding tube 106 arranged on the winding spindle 104, respectively. Hang and / or may be positioned at a take-up spindle position that can contact and / or capture the take-up spindle 104 supported by the spindle turret 105 and / or the take-up spindle 104 moved by the spindle turret 105.

[0105] The above-mentioned winding spindle positions may be achieved by the suction unit 14 and / or the yarn winding unit 15, which are shown diagrammatically in FIG. Hanging This may correspond to the position of the auxiliary device or to a position arranged further down in the y-direction.

[0106] The threaded and longitudinally distributed melt-spun yarn 102 is wound on a winding spindle 104 or a winding tube 106 arranged on the winding spindle 104, respectively. Hanging In order to ensure that the longitudinal alignment device or the lower transition unit 124 is aligned with the winding spindle 104, the longitudinal alignment device or the lower transition unit 124, respectively, can perform a depth-offset operation in a depth-offset direction, which may in particular extend at an angle to the longitudinal direction of the winding spindle 104, in particular transversely to the longitudinal direction of the winding spindle 104 or along the vertical direction and / or along the x-direction, respectively.

[0107] To perform the depth offset operation, the locking hook 126 may be moved in a depth offset direction along with each guide of the locking hook 126, and the threaded melt spun yarn 102 may be entrained in the depth offset direction, respectively.

[0108] When a depth offset operation is performed, the take-up spindle 104 on which the winding tube 106 - not yet wound - is disposed may be moved or pivoted by a spindle turret 105 (shown in FIG. 4) from a doffing position to a winding position. As a result of this type of movement or pivoting from the doffing position to the winding position, the melt spun yarn 102, which has moved in the depth offset direction, contacts the take-up spindle 104 or the winding tube 106 disposed on the take-up spindle 104, respectively, where the yarn Hanging It is possible.

[0109] The melt spun yarn 102 is wound on a winding spindle 104 or a winding tube 106 disposed on the winding spindle 104, respectively. Hanging After this, movement of the take-up spindle 104 can continue to the winding position, where each winding process can be performed and completed, after which the take-up spindle 104 can be returned to the doffing position shown in Figures 4-10.

[0110] In the winding position, the winding spindle 104 is disposed vertically or in the y-direction approximately at the level of the longitudinal alignment device or the lower transition unit 124, respectively. When viewed transversely or in the x-direction, respectively, relative to the drawing plane of Figures 5 to 10, the winding spindle 104 is disposed behind the longitudinal alignment device or the lower transition unit 124, respectively.

[0111] Each of the longitudinal alignment devices or lower transfer units 124 may include a cutting device that allows cutting or severing of each melt spun yarn 102. Such a cutting device may, in particular, be adapted to cut or sever each melt spun yarn 102 by contacting each take-up spindle 104 and separating the yarn from the respective take-up spindle 104. Hangingand may be configured and / or defined to effect a cut or severance of each melt spun yarn 102 when the take-up spindle 104 reaches the take-up position or immediately before it reaches the take-up position.

[0112] Thus, the winding process can be initiated by the longitudinal alignment device or lower transfer unit 124 after each melt spun yarn 102 is cut or severed, and the cut or severed remnants of the melt spun yarn 102 can be sucked up by the suction unit 14, thereby avoiding any disruption of the winding process by the cut or severed remnants.

[0113] As noted above, in each of the Figures 4-10, a wound package 108 is shown, which is configured to wound the melt spun yarn 102 into a yarn Hanging This can only occur by subsequent complete winding onto the winding tube 106. Upon completion of the winding process, the wound package 108 is removed from the winding spindle 104 in the doffing position shown in Figures 4 to 10, and a new, not yet wound, winding tube 106 can be attached to the winding spindle 104. A new winding process can then be performed. [Explanation of symbols]
