Definitions

  • the thread touches the inside of the passage opening and only the thread causes the thread guide element to rotate due to its rotatable arrangement.
  • Ring spinning machines of the type mentioned are, for example, from the DE 199 09 501 A1 known.
  • a sliver is formed into a thread that is wound onto a cop in the ring spinning machine.
  • the ring spinning machine has a large number of spinning positions, at which a large number of slivers are simultaneously formed into threads, which are wound onto a large number of cops.
  • An essential part of a spinning station of the ring spinning machine is the drafting system and the spindle of the ring spinning device.
  • the sliver is drafted, with the drafting system having at least one pair of input rollers and one pair of output rollers for this purpose.
  • the lines of contact between the rollers of the roller pairs form a nip line through which the sliver is guided.
  • One or more further pairs of rollers can be arranged between the input and output pairs of rollers. Drafting systems with a total of three or four pairs of rollers are common. The delay or the stretching of the sliver is realized by a speed difference between the pairs of rollers.
  • the fibers of the sliver are rotated and are thereby transformed into a thread.
  • the rotation is generated by the spindle, which rotates the cop on which the thread is wound.
  • various yarn guide elements such as a traveling yarn guide, a balloon constriction ring and a spinning ring are known. These elements are in contact with the thread and, due to their friction, influence the twist propagation in the thread, which in turn influences the spinning result.
  • the DE 2 343 776 A1 discloses a spinning position of a ring spinning machine with a yarn guide arranged above the spindle, which is rotatably mounted by means of a ball bearing.
  • the yarn guide and the spindle each have a magnet arrangement which is designed in such a way that the yarn guide is carried along by the rotating spindle through the magnetic field of the magnet arrangements.
  • the twine guide rotates at a speed similar to the speed of the spindle.
  • the additional twist is intended to prevent yarn breakage from occurring.
  • the construction with the magnet arrangements is relatively complex.
  • the drive of the yarn guide with the magnet arrangements requires a fixed distance between the spindle and the yarn guide. This means that the yarn guide cannot be moved up and down, as is usual with wandering yarn guides.
  • the magnet arrangement on the spindle also makes doffing more difficult.
  • the DE 30 21 632 A1 also discloses a rotatably mounted, rotatingly driven thread guide of the spinning station of a ring spinning machine. This is intended to improve the evenness of the yarn produced.
  • the generic utility model CN 204661928 U discloses a yarn guide member for a ring spinning machine having an inner peripheral surface and an outer peripheral surface. Cylindrical rolling elements are arranged between the surfaces. During spinning, the thread is passed through the inner surface. When the thread passes the inner peripheral surface, the inner surface can rotate in the direction of twist impartation.
  • the thread uniformity and the reduction of thread defects in the thread produced are limited by the known ring spinning machines and the known methods for operating a spinning station of a ring spinning machine or require complex, otherwise restrictive constructions.
  • the invention is based on the object of providing a ring spinning machine and a method for operating a spinning position of a ring spinning machine, by means of which the production of a thread with a particularly high degree of thread uniformity and low thread defects is possible in a simple manner.
  • the invention solves the problem by a ring spinning machine with the features of claim 1 and a method for operating a spinning station of a ring spinning machine according to the features of claim 6.
  • Advantageous developments of the ring spinning machine are specified in the dependent claims 2 to 5.
  • the ring spinning machine according to the invention is characterized in that the respective spinning positions of the ring spinning machine have a thread guide element with a rotationally symmetrical passage opening for the thread, the thread guide element being arranged such that it can rotate about the longitudinal axis of the passage opening in the region between the drafting system and the end of the spindle facing the drafting system.
  • the thread guide element is designed and arranged in such a way that the thread touches the inside of the through-opening through the rotating spindle of the ring spinning device, which is arranged downstream of the thread guide element in the direction of thread travel, and that only the thread causes the thread guide element to rotate due to its rotatable arrangement.
  • the drafted sliver emerging from the drafting system is guided through the through-opening of the thread-guiding element before it enters the ring spinning device. Due to the rotating spindle of the ring spinning device, which is arranged downstream of the thread guide element in the direction of thread travel, the thread touches the inside of the passage opening and causes the thread guide element to rotate due to its rotatable arrangement, with the axis of rotation running parallel to the thread path.
  • the thread has a particularly high quality, in particular a particularly high degree of thread uniformity and only very few thread defects.
  • the high quality of the thread results from the interaction of the rotating inside of the through-opening of the thread-guiding element with the thread guided through the through-opening.
  • the invention is also based on the finding that it is not necessary to actively drive the rotatably arranged thread guide element in order to achieve a desired thread uniformity. Rather, it is sufficient if the rotatable thread guide element is driven by the thread itself. An additional drive device is not required.
  • the through-opening tapers at least in sections in the direction of the spindle.
  • the through-opening has a funnel-shaped section, for example, in which the cross-section of the through-opening tapers in the running direction of the thread.
  • the thread guide element can be designed in such a way that the passage opening tapers continuously from an inlet opening of the thread guide element to an outlet opening of the thread guide element.
  • the thread guiding element can also have sections in which the cross section of the passage opening is constant in the running direction of the thread.
  • the tapering section ensures a particularly reliable rotation of the thread guide element around the thread and thus interaction of an inside of the through-opening with the thread, so that the thread has a particularly high quality.
  • the inside of the through-opening has ring-shaped projections.
  • the inside of the through-opening does not have a smooth surface, but is provided with one or more annular projections which protrude in the direction of the longitudinal axis of the through-opening and are arranged coaxially with the longitudinal axis. Due to the projections, the thread does not engage with the entire inside of the through-opening of the thread guide element, but rather only rests against the projections in the area of the annular projections and does not engage with the inside of the through-opening in the area of the depressions running between the projections.
  • the partial interaction of the inside of the passage opening with the thread produced by the projections results in a particularly high degree of thread uniformity and a very small number of thread defects.
  • the configuration of the projections can in principle be freely selected. According to a particularly advantageous embodiment of the invention, however, it is provided that the projections are formed by a thread, which is arranged on the inside of the through-opening.
  • the use of a thread to form the projections is characterized in that they can be produced in a particularly simple and cost-effective manner.
  • the number of projections running over the entire circumference of the inside can be determined in a particularly simple manner via the length of the thread.
  • one to six, preferably two to five, particularly preferably three to four annular projections are provided.
  • the use of the thread guiding element according to the invention in the area between the drafting system and the ring spinning device results in a particularly high thread quality of the thread converted from the sliver.
  • a wandering thread guide is arranged in the area between the thread guide element and the end of the spindle facing the drafting system.
  • the use of a yarn guide which can be adjusted in the direction of the longitudinal axis of the spindle and is therefore referred to as a traveling yarn guide, increases the spinning geometry in a complementary way through its rotation propagation resulting from the friction.
  • the rotatable arrangement of the thread guide element can be freely selected. In its simplest configuration, it can be used in loose form, with the thread only being guided through the through-opening.
  • an eyelet can be provided which is arranged in the area between the drafting system and the spindle and prevents a displacement of the thread guide element in the direction of the spindle.
  • the thread guide element can be designed in such a way that it rests loosely on the wandering thread guide.
  • the thread guide element is rotatably arranged on the wandering thread guide.
  • a bearing is provided by means of which the thread guide element is rotatably mounted on the wandering thread guide.
  • the design of the bearing is in principle freely selectable and ensures a stationary arrangement of the thread guide element at the spinning station in a particularly reliable manner.
  • the wandering thread guide can be adjusted in the direction of the longitudinal axis of the spindle. The adjustment is made depending on the bobbin structure and enables the yarn balloon, which is formed by the rotating yarn, to be influenced and thus the spinning geometry to be optimized.
  • an arrangement can be provided, for example, in which the thread guide element in the area its funnel-shaped section is loosely rotatably mounted in an eyelet of the traveling thread guide.
  • the thread guide element can also be arranged on the moving thread guide by means of a roller bearing.
  • a sliver is fed to a drafting system and drafted in the drafting system and then, after exiting the drafting system, the drafted sliver is fed to a ring spinning device downstream of the drafting system, in which the drafted sliver is a thread is wound on a arranged on a spindle cop.
  • the thread is guided after the drafting system through a rotationally symmetrical through-opening of a thread guide element, which is arranged in the area between the drafting system and the end of the spindle facing the drafting system so that it can rotate about the longitudinal axis of the through-opening.
  • the drawn sliver is set in rotation by the rotating spindle and spun into a thread which is then wound onto the cop arranged on the spindle.
  • the thread touches the inside of the passage opening of the thread guide element due to the rotating spindle and causes it to rotate, with the axis of rotation being aligned parallel to the running direction of the thread.
  • the thread guide element has annular projections on the inside of the through-opening. According to the invention, the thread in the area of the ring-shaped projections is only in contact with the projections. Due to the interaction of the inside of the thread guide element with the thread, a particularly high thread quality with high thread uniformity and few thread defects is produced.
  • figure 1 is a schematic representation of a drafting system 1 and a ring spinning device 10 downstream of the drafting system 1 of a spinning position of a ring spinning machine, which has a large number of centrally driven spinning positions arranged next to one another.
  • the essential components of the spinning positions are the drafting system 1 and a spindle for receiving a cop 12.
  • the drafting system 1 has four pairs of rollers, the pair of input rollers (not shown), the pair of middle rollers 4, the pair of output rollers 3 and the pair of transport rollers 2 of a compression device.
  • the pairs of rollers 2, 3, 4 each consist of an upper roller 2a, 3a, 4a and a lower roller 2b, 3b, 4b.
  • the middle roller pair 4 accordingly consists of a middle upper roller 4a and a middle lower roller 4b.
  • the middle upper roller 4a and the middle lower roller 4b are each wrapped around by a delay strap.
  • the pair of output rollers 3 has an output upper roller 3a and an output lower roller 3b which form a nip line in their line of contact.
  • the pair of transport rollers 2 of the compaction device consists of a transport upper roller 2a, which is wrapped by a compaction apron, and a transport lower roller 2b.
  • the upper transport roller 2a and the lower transport roller 2b also form a clamping line and, in the exemplary embodiment shown, also the rotation blocking gap up to which the rotation generated by the spindle of the ring spinning device 10 propagates. Without the compression device, the anti-rotation nip would be formed by the exit roller pair.
  • the bottom rollers 2b, 3b, 4b are each driven via a common shaft.
  • the upper rollers 2a, 3a, 4a are rotatably mounted in a carrying and loading arm and are pressed against the lower rollers 2b, 3b, 4b.
  • the top rollers 2a, 3a, 4a are then carried along by friction.
  • the sliver first runs through the input nip line between the input top roller and the input bottom roller.
  • the sliver then runs through the center roller pair 4 and the output roller 3.
  • the sliver leaves the drafting system 1.
  • the sliver receives a delay.
  • a twist, through which the sliver becomes a thread takes place downstream of the rotation blocking nip.
  • a cop 12 is arranged on a spindle. Above the cop 12, the thread runs through an eyelet-forming tail 8 of a traveling thread guide 5, which is arranged via receiving openings 6 of fastening rings 17 on a holder 7 on a machine-long lifting device and enables the traveling thread guide 5 to be displaced along the longitudinal axis of the spindle. There is also a balloon constriction ring 11 which is arranged on a carrier 15 . The balloon constriction ring 11 limits the thread balloon that forms when the thread is wound up. A ring rail, not shown, moves up and down along the spindle as a cop is built up. A spinning ring 13 assigned to each spinning station is arranged on the ring rail.
  • a ring traveler which is driven by the rotating thread balloon, rotates on the spinning ring 13 .
  • the thread is rotated by the cop 12 rotating on the spindle.
  • the movement propagates up to the anti-rotation gap of the drafting system 1 and is stopped there.
  • a thread guide element 9a, 9b with a through-opening for receiving the thread is rotatably arranged.
  • the thread guide elements 9a, 9b rest loosely on the pigtail 8 of the traveling thread guide 5. Due to the rotating spindle, the thread touches the inside 18a, 18b of the passage opening of the thread guide elements 9a, 9b and causes them to rotate. The axis of rotation is parallel to the grain.
  • the thread guide element 9a on the outside in cross section hexagonal shape like a nut.
  • the thread guide element 9a rests loosely on the pigtail 8.
  • the thread guide element 9a has four projections 19 which protrude inwards in the direction of the thread and which are formed by an internal thread 20.
  • the thread guide element 9b has a conical section 21 following a cylindrical section, so that the passage opening tapers in the direction of the thread path.
  • the thread guide element 9b In an upper section--related to the position of use--the inside 18b of the thread guide element 9b also has projections 19, which are formed by a thread 20.
  • the conical section 21 adjoins the cylindrical section.
