Description

[0001] Various embodiments relate to a textile machine, a thread length compensation device and a method for producing a textile structure.

[0002] Threads can generally be processed into a textile structure using a textile machine, such as a weaving machine or a knitting machine. For example, the threads can be provided as warp threads on a reel, the warp beam, then fed to a work station on the textile machine where the textile structure is formed from the threads, and then the textile structure can be removed.

[0003] Typically, the threads are fed in and out at an essentially constant (i.e., consistent) speed. Threads processed together (e.g., uniformly) are also referred to as a thread sheet. However, a movement of working elements at the work station can lead to a situation where the demand for threads (also referred to as the thread requirement) is not constant. For example, the thread requirement can temporarily be smaller or larger than that supplied by the warp beam at a constant speed. In the case of a knitting machine, the movement of the working elements can, for example, be a swinging movement of a guide bar (e.g., one equipped with guide needles) (also referred to as a guide rail and / or guide needle bar) and / or a lifting movement of knitting needles.As can be seen, the thread requirement at the work station can be highly discontinuous due to the swinging of the guide bars around the needles and the formation of the thread loops, which can lead to extremely different thread speeds and thus accelerations in the thread path, which can lead to vibrations and differences in tensile force in the thread sheet.

[0004] Therefore, it may be necessary (e.g., to ensure process reliability) to retract the unused, i.e., released, thread lengths. This can be achieved by tensioning the threads. This tensioning of the threads is also referred to as thread length compensation. It may also be necessary (e.g., to ensure process reliability) to release thread lengths (in the other direction) if the thread requirement is greater than the supplied thread length (this could otherwise only be compensated by structural and / or material-inherent stretch).

[0005] Traditionally, mobile textile machine-specific deflection elements (e.g., a backrest in the case of a weaving machine, a thread rocker in the case of a warp knitting machine) are used for this purpose. These deflection elements are arranged across the width of the yarn sheet and are deflected out of a plane spanned by the yarns in order to tension the yarns in this way. For illustration, Fig. 4 shows such a conventional textile machine 400 in a schematic side view. Here, threads 404 (e.g. warp threads) can be provided on a warp beam 402 and fed to a work station 408 by means of a deflection element 406 (e.g. a backrest in the case of a weaving machine or a thread rocker in the case of a warp knitting machine). At the work station 408, a textile structure 410 can be formed from the threads 404 and then optionally guided away by means of other deflection elements 412 and rolled up onto another roll (e.g. a cloth beam) 414. The deflection element 406 can be configured such that it can be deflected out of the plane formed by the threads 404 (i.e. in direction 40) in order to tension the threads 404 depending on the thread requirement. Consequently, the deflection element 406 can serve for thread length compensation (and can therefore also be referred to as a thread length compensation element).The thread length compensation element can also be coupled to a passive (spring) or active drive (coupling gear, motor) and can then be referred to as a thread length compensation device.

[0006] DD 2 75 491 A1 discloses a device for adjusting the sewing thread feed to the sewing thread requirement on a stitch-bonding machine. DE 195 37 215 A1 shows a thread delivery device for elastic yarns.

[0007] According to various aspects, it was recognized that this type of deflection, caused by the arrangement of the thread length compensation device above the thread sheet plane (thread sheet plane 11-15) and the orientation of the thread tension forces perpendicular to this arrangement (in direction 13), leads to considerable bending and torsional forces acting on the thread length compensation element 107, and that this requires (for example, with active thread length compensation) solidly designed components of comparatively high mass. In this regard, it was recognized that (due to the design of the thread length compensation element as a spring-mass system) this high mass leads to a reduction in the natural frequency of the deflection elements, which limits the machine speed of the textile machine up to which the thread lengths can be (exactly) compensated by means of the deflection element.This limit for machine speed can be approximately 2200 courses per minute on warp knitting machines when processing yarns with low elastic elongation. Due to the excitation of the system in its natural frequency range, it can no longer follow the different yarn speeds proportionally, which can lead to an increase in the vibrations of the deflection elements, thus making reliable compensation of the different yarn length differences impossible.

[0008] Various aspects relate to a thread length compensation principle that enables a significant reduction in the mass of the thread length compensation element. This allows, for example, the natural frequency of the thread length compensation element to be increased, thereby increasing the machine speed of the textile machine up to which the thread lengths can be (exactly) compensated by the thread length compensation element (e.g., to approximately 3,000 courses per minute or more, e.g., to approximately 4,000 courses per minute or more).

[0009] This is achieved by deflecting the thread length compensation element not out of the plane spanned by the threads, but within the plane. As a result, the direction of the arrangement of the thread length compensation element across the thread sheet width (direction 15) and the forces acting on it in direction 15 resulting from the thread tension forces are identical, and only tensile and compressive forces arise in the thread length compensation element. This allows the mass of the thread length compensation element to be significantly reduced. Furthermore, the forces required for thread length compensation can be significantly reduced while maintaining the same thread tension forces.

[0010] Various embodiments relate to a textile machine, comprising: a thread feed device for feeding threads as a thread sheet to a work station, wherein the thread sheet runs between the thread feed device and the work station at least in a section in a thread sheet plane; a working device for processing the threads at the work station into a textile structure; and a thread length compensation device which is arranged in the section and which is configured for thread length compensation, wherein the thread length compensation device has a first and a second guide element and a thread length compensation element arranged therebetween with a deflection mechanism which enables a deflection of the thread sheet in the thread sheet plane.

[0011] It shows Fig. 1A to 1F each show aspects of a textile machine according to various embodiments; Fig. 2 a thread length compensation device according to various embodiments; Fig. 3 shows a flow diagram of a method for producing a textile structure according to various embodiments; and Fig. 4 a conventional textile machine.

[0012] In the following detailed description, reference is made to the accompanying drawings, which form a part hereof, and in which is shown by way of illustration specific embodiments in which the invention may be practiced.

[0013] Various aspects relate to a principle of thread length compensation, in which thread lengths are compensated by deflecting the threads in a plane spanned by the threads. As a result, the direction of the arrangement of the thread length compensation element across the thread sheet width and the forces resulting from the thread tension forces are identical, and only tensile and compressive forces arise in the thread length compensation element. This allows the forces required for thread length compensation to be reduced while maintaining the same thread tension forces. Furthermore, the thread length compensation element configured for thread length compensation can be designed with a reduced mass, thereby increasing the machine speed up to which the thread lengths can be (exactly) compensated.

[0014] Fig. 1A to Fig. 1F each show aspects of a textile machine 100 according to various embodiments. In general, the textile machine 100 can be configured to produce a textile structure 114. The textile structure 114 can be a knit fabric consisting of interlocking thread loops formed by a plurality of threads 104. The formation of the thread loops can take place at a work station 108. Consequently, threads 104 can be fed to the work station 108 and removed therefrom as a textile structure 114. The work station 108 can also be referred to as a loop-forming zone and / or (in the case of a knitting machine) as a knitting station.

[0015] The threads 104 fed to the work station 108 can run parallel to one another. Threads 104 running parallel to one another can also be referred to as a thread group and / or as a (e.g., knitting) thread system. These threads 104 of the thread group can be warp threads. In a warp knitting process, one or more thread groups can be formed into stitches simultaneously.

[0016] The textile machine 100 can have a thread feed device 102. The thread feed device 102 can be configured to feed the threads 104 (e.g., warp threads) as a sheet of threads to the work station 108. The thread feed device 102 can, for example, be or comprise a warp beam. Clearly, the threads 104 can be stored on the warp beam. The thread feed device 102 can have a drive so that the threads 104 can be fed by rotation of the warp beam.

[0017] According to various aspects, the yarn feed device 102 can be configured to feed the yarns 104 at a substantially constant speed. Feeding the yarns 104 at a substantially constant speed may be necessary because this can affect the yarn tension (also referred to as process yarn tension) and thus also the fabric properties (e.g., stitch size and uniformity, stretch properties, etc.) and quality of the produced textile structure 114.

[0018] The textile machine 100 can have a working device at the work station 108. The working device can be configured to process the threads 104 at the work station 108 into the textile structure 114 (e.g., by stitch formation). In this case, the working device can be configured to move the threads 104 and connect them to the textile structure 114 in such a way that a thread requirement is temporarily changed (e.g., reduced). A changed thread requirement can, for example, lead to a reduced tensile force acting on the threads 104. This tensile force can also be approximately 0 N in absolute terms, which could lead to one or more defects in the textile process, such as thread breakage due to incorrect interventions by one or more working elements.

[0019] The textile machine 100 can be any type of (thread-processing) textile machine 100. In some embodiments, the textile machine 100 can be a knitting machine (e.g., a warp knitting machine, a (right-left or right-right) Raschel machine, etc.). In this case, the working device can, for example, have a guide bar for laying the threads 104. In other embodiments, the textile machine 100 can be a weaving machine. In this case, the working device can have a shedding device. In some embodiments, the shedding device can, for example, have at least two heald shafts for moving the threads 104 (e.g., arranged in heddles of the at least two heald shafts). In other embodiments, the shedding device can have or be a jacquard device (in this case, the weaving machine can be a jacquard weaving machine).It is understood that these are exemplary embodiments of the textile machine 100 and the textile machine 100 may also be any other type of textile machine for which compensation of thread lengths can be used (e.g. is required).

[0020] As explained above, a substantially constant thread tension can be crucial for the properties and quality of the produced textile structure 114. Therefore, it may be desirable and / or necessary to compensate for the thread requirement released at work station 108. This thread length compensation can clearly be a balance between continuous material input by means of thread feed device 102 and discontinuous processing of the threads 104 at work station 108.

[0021] The textile machine 100 may comprise a take-off device (e.g. comprising a breast beam 116 and / or a cloth beam 118) for removing the textile structure 114 (see, for example, Fig. 1C). Illustratively, the work station 108 can be arranged between the thread feed device 102 and the take-off device. According to various aspects, the take-off device (e.g., using the cloth beam 118) can be configured to remove the textile structure 114 at a substantially constant speed.

[0022] According to various aspects, textile machine 100 may include a thread length compensation device 150. Thread length compensation device 150 may be configured for thread length compensation. According to various aspects, threads 104 in (at least) one section 10 may extend parallel to one another as a thread sheet and in a plane (e.g., spanned by directions 11 and 15) (hereinafter referred to as thread sheet plane 11-15).

[0023] With reference to Fig. 1D to Fig. 1F, the textile machine 100 may comprise a first guide element 120 for guiding the threads 104 and a second guide element 122 for guiding the threads 104. The section 10 may extend from the first guide element 120 to the second guide element 122. For example, the section 10 may comprise the first guide element 120, the second guide element 122, and the thread length compensation element 107. Consequently, the threads 104 may extend as a thread sheet between the first guide element 120 and the second guide element 122 in the thread sheet plane 11-15.

[0024] According to various aspects, the thread length compensation device in section 10 can have a length ranging from approximately 100 mm to approximately 300 mm. This length can be advantageous for the thread length compensation described herein. In this case, the design of textile machine 100 can result in a predetermined thread tension and / or a thread length to be compensated. According to various aspects, with increasing length of the section 10, one or more of the following (technically relevant) parameters can be adjusted: a path of deflection of the thread length compensation element 107 (e.g., of the thread length compensation comb 207) can be or be increased, a force for deflecting (and thereby tensioning) the threads 104 can be or be reduced, a sum of the deflection angles for the threads 104 can be or be reduced (thus, for example, the friction of the threads 104 in the thread length compensation element 107 (e.g.,the thread length compensation comb 207) and optionally further in the first guide element 120 and / or the second guide element 122).

[0025] In some embodiments, the first guide element 120 and / or the second guide element 122 can be an additional guide element (e.g., the first guide element 120 can be a first guide comb 110 and / or the second guide element 122 can be a second guide comb 112) between the thread feed device 102 and the work station 108. In various embodiments, the thread feed device 102 (e.g., the warp beam) can be the first guide element 120. In various embodiments, an element at the work station 108 (e.g., a guide comb (also referred to as a thread comb) of the guide bar) can be the second guide element 122.

[0026] A guide element can be designed as a guide comb. A guide comb can be an open guide comb or a closed guide comb (e.g., an eyelet plate).

[0027] According to various aspects, the first guide element 120, the thread length compensation element 107, and the second guide element 122 can be arranged at the work station 108. In an exemplary embodiment, the first guide element 120, the thread length compensation element 107, and the second guide element 122 can be part of a thread length compensation guide bar 200 (see, for example, Fig. 2 and associated description).

[0028] According to various aspects, the thread length compensation element 107 can be arranged in the section 10. The thread length compensation device 150 can have a deflection mechanism which, with the thread length compensation element 107, enables a deflection of the thread sheet in the thread sheet plane. For example, the deflection mechanism can be configured to deflect the threads 104 of the thread sheet in the thread sheet plane 11-15. According to various aspects, the deflection mechanism can be configured to deflect the threads 104 of the thread sheet in direction 15 and / or opposite direction 15 (see, for example, Fig. 1E). Fig. 1F shows an example of a thread length compensation element 107 deflected in direction 15.

[0029] Illustratively, the deflection mechanism can enable a deflection of the yarn sheet in the yarn sheet plane 11-15 perpendicular to a longitudinal extension of the yarns (in direction 11). Illustratively, the deflection mechanism of the yarn length compensation device 150 can be configured such that no deflection occurs in direction 13 or opposite to direction 13.

[0030] The deflection mechanism can comprise a passive deflection mechanism and / or an active deflection mechanism. An active deflection mechanism can comprise a control device that provides the deflection through active control.

[0031] According to various aspects, the thread length compensation device 150 may include a thread length compensation element 107 (e.g., a thread length compensation comb 207) coupled to the threads 104 of the thread sheet in the section 10. The thread length compensation device 150 may further include one or more other elements that enable deflection of the thread length compensation element 107, thus providing the deflection mechanism.

[0032] For example, in the case of the active deflection mechanism, the thread length compensation device 150 may comprise a drive element configured to drive the thread length compensation element 107 in order to deflect the thread length compensation element 107 and the thread sheet coupled to the thread length compensation element 107 in the thread sheet plane 11-15. In this case, the textile machine 100 may comprise the control device, which may be configured to control the drive element in order to thereby control the deflection of the thread length compensation element 107.

[0033] According to various aspects, textile machine 100 may include a detection unit configured to detect a thread requirement (e.g., represented by a freed thread length, a tensile force of the threads, etc.) and to provide information regarding the detected thread requirement to the control device. The control device may be configured to control the drive element such that the threads in the section are deflected (and thereby tensioned) according to the detected thread requirement or the detected thread tensile force.

[0034] As used herein, closed-loop control can be understood as controlling, wherein a change in state caused by disturbances is additionally counteracted. For this purpose, an actual state of the deflection of the thread length compensation element 107 can be compared with a desired state, and the deviation of the actual state from the desired state can be minimized. Therefore, as used herein, closed-loop control can be performed alternatively or in addition to open-loop control. For illustrative purposes, the control device in this case can also be referred to as a closed-loop control device.

[0035] According to various aspects, the control can be configured such that the thread tension force is detected indirectly via the drive force (e.g. drive torque) of the thread length compensation element 107, and the control is carried out as a function of the (known) deflection of the thread length compensation element such that the thread tension force in the thread sheet remains constant regardless of the position of the thread length compensation element.

[0036] The drive element may comprise any suitable type of drive, such as comprising one or more of the following drive elements: one or more cams, one or more chain links, one or more crank drives, a pneumatic drive element, a hydraulic drive element, one or more linear motors, one or more servo spindle drives, etc.

[0037] As explained herein, the thread length compensation device 150 can be configured such that the deflection mechanism enables deflection of the thread length compensation element 107 with the thread sheet in both directions (i.e., in direction 15 and opposite to direction 15) in the thread sheet plane 11-15 (perpendicular to the longitudinal extension of the threads 104 in direction 11). In this way, the frequency of the drive (by means of one or more drive elements) can be halved compared to a unilateral deflection.

[0038] For example, in the case of the passive deflection mechanism, the deflection mechanism can be provided with a spring mechanism. For example, the thread length compensation device 150 can have at least one spring element that provides the spring mechanism. The spring mechanism can be configured to deflect the thread length compensation element 107 and the thread sheet coupled to the thread length compensation element 107 according to a prestressing force (e.g., a tensile force or a compressive force) in the thread sheet plane 11-15. For example, the at least one spring element can have at least one tension spring that provides a tensile force (as a prestressing force) in direction 15 and / or opposite direction 15. For example, the at least one spring element can have at least one compression spring that provides a compressive force (as a prestressing force) in direction 15 and / or opposite direction 15.For example, the at least one spring element can comprise at least one tension spring which provides a tensile force (as a preload force) in direction 15, and at least one compression spring which provides a compressive force (as a preload force) in the opposite direction 15 (or vice versa). For example, the at least one spring element can comprise a first tension spring which provides a first tensile force in direction 15, and at least one second tension spring which provides a second tensile force opposite direction 15. For example, the at least one spring element can comprise a first compression spring which provides a first compressive force in direction 15, and at least one second compression spring which provides a second compressive force opposite direction 15.

[0039] The spring mechanism can be clearly provided by at least one tension spring and / or at least one compression spring. A spring (e.g., tension spring, compression spring) can be provided by any suitable spring principle. For example, at least one spring can be made of steel or elastane or a fiber composite material. For example, at least one spring can be a magnetic spring (e.g., a MagSpring® spring). A magnetic spring can be understood as a magnet system that provides a defined (e.g., constant with variable deflection) thread tension force and thus the spring mechanism. Therefore, the magnetic spring can provide a constant spring force independent of the spring travel. For example, the spring mechanism can be a pneumatic spring mechanism. Optionally, the thread length compensation device 150 can be configured such that a spring stiffness of the spring mechanism is adjustable (e.g.,by means of one of the springs, a lever system, etc.).

[0040] According to various aspects, the deflection mechanism can comprise the active deflection mechanism and the passive deflection mechanism (e.g., a spring element of the passive deflection mechanism can be arranged between the thread length compensation element 107 and the drive element). According to various aspects, the control device can be configured to actively control (e.g., to regulate) the deflection mechanism and to also design at least one guide element (e.g., 110 and / or 112) to be movable in the direction 15 in the thread sheet plane and to couple it to a passive deflection mechanism. In this way, the dimensions of the drive element(s) of the active deflection mechanism can be significantly reduced, whereby the textile machine 100 can be more compact and / or costs (e.g., manufacturing costs and / or operating costs) can be reduced.

[0041] Clearly, the thread length compensation element 107 is only subjected to pressure and / or tension (and not to bending and torsion) by this type of lateral deflection (in the thread sheet plane 11-15 in direction 15 and / or opposite direction 15), whereby the mass of the thread length compensation element 107 can be reduced.

[0042] As explained above, according to various aspects, the first guide element 120, the thread length compensation element 107 and the second guide element 122 may be part of a thread length compensation guide bar 200. Such a thread length compensation guide bar 200 is shown schematically for illustration purposes in Fig. 2 shown.

[0043] The thread length compensation guide bar 200 can have a guide comb 202. The guide comb 202 can be configured to guide the threads 104 (as a thread sheet). The thread length compensation guide bar 200 can have a plurality of guide needles 204. The thread length compensation guide bar 200 can be configured such that the threads 104 run between the guide comb 202 and the plurality of guide needles 204 as a thread sheet in the thread sheet plane 11-15.

[0044] Illustratively, the guide comb 202 of the thread length compensation guide bar 200 can form the first guide element 120 and the plurality of guide needles 204 can form the second guide element 122.

[0045] The thread length compensation guide bar 200 can have a thread length compensation element 206. The thread length compensation guide bar 200 can have a thread length compensation comb 207 (e.g., as thread length compensation element 107). The thread length compensation comb 207 can be coupled to a deflection mechanism that enables a deflection of the thread sheet in the thread sheet plane 11-15 (e.g., in direction 15 and / or opposite direction 15). The thread length compensation comb 207 can be configured as described above with respect to the thread length compensation element 107. For example, the deflection mechanism of the thread length compensation comb can have the active deflection mechanism and / or the passive deflection mechanism.

[0046] The guide comb 202, the plurality of guide needles 204, and the thread length compensation comb 207 can be attached to a guide bar 208. Illustratively, the guide bar 208 can be equipped with the plurality of guide needles 204. Fig. 2 further shows a knitting needle 210.

[0047] Fig. 3 shows a flow diagram of a method 300 for producing a textile structure according to various embodiments.

[0048] Method 300 may include guiding threads (e.g., warp threads) as a thread sheet (in 302). In this case, the thread sheet may extend in a thread sheet plane at least in one section.

[0049] Method 300 may include processing the threads into a textile structure (at 304). In this process, thread requirements may change (for example, releasing thread lengths).

[0050] The method 300 may include tensioning the threads in the section by deflecting the thread sheet in the thread sheet plane (e.g., perpendicular to a longitudinal extent of the threads) (in 306).

[0051] Optionally, method 300 may include detecting the thread requirement or the thread tension. Method 300 may include controlling (e.g., regulating) a drive element configured to deflect a deflection element coupled to the thread sheet in the section such that the threads in the section are deflected (and thereby tensioned) according to the detected thread requirement.

[0052] Various examples are provided below that describe one or more aspects of the textile machine 100, the thread length compensation device 150, the thread length compensation guide bar 200, and the method 300. It is understood that aspects described with respect to the textile machine 100 and / or the thread length compensation device 150 and / or the thread length compensation guide bar 200 may also apply to the method 300, and vice versa. For example, capabilities for which one or more components of the textile machine 100 and / or the thread length compensation device 150 and / or the thread length compensation guide bar 200 are configured may be implemented accordingly in a method.
