Definitions

  • the present invention relates to a guide device for a ring spinning machine for guiding a strand-shaped fiber structure with a guide area which limits freedom of movement of the fiber structure perpendicular to a running direction of the fiber structure and with an opening for introducing the fiber structure into the guide area.
  • the invention also relates to a ring spinning machine with at least one workstation for producing a yarn, the workstation having a drafting system for stretching a fiber structure, a ring traveler rotating on a spinning ring and a guide device for guiding the fiber structure.
  • the invention relates to the use of a guide device in a ring spinning machine.
  • Ring spinning machines for producing a yarn from a fiber structure have been known for a long time.
  • ring spinning machines have a drafting system for stretching the fiber structure. After the drafting system, the stretched fiber structure is wound onto a spinning tube via a ring runner rotating on a spinning ring. This gives the fiber structure a twist and turns it into a yarn.
  • the ring spinning machine usually has at least one guide device, through which at least one movement of the fiber structure is limited perpendicular to its direction of travel. On the one hand, the guide device can prevent unwanted movements of the fiber structure.
  • the tension of the fiber structure can also be specifically controlled by the guide device.
  • Known guide devices generally have an opening for threading the fiber structure on, via which the fiber structure can be brought into a guide area of the guide device, for example before spinning again.
  • Such known guide devices are, for example, spirally bent wires, such as those in DE 35 20 864 A1 or the US 4,114,829 A are revealed.
  • a disadvantage of the known guide devices is that it is difficult to thread the fiber structure, especially using a service robot, as has recently been used more and more frequently in ring spinning machines.
  • cleaning the known guide devices also involves increased effort, since fibers that come loose from the fiber structure easily get stuck on the turns of the wire.
  • the object of the present invention is to eliminate the disadvantages known from the prior art, in particular to create a guide device for a ring spinning machine which overcomes the disadvantages mentioned.
  • the task is solved by a guide device, a ring spinning machine and the use of a guide device with the features of the independent claims.
  • the guide device for a ring spinning machine for guiding a strand-shaped fiber structure with a guide area that limits freedom of movement of the fiber structure perpendicular to a running direction of the fiber structure and with an opening for introducing the fiber structure into the guide area.
  • the guide device has a first guide element with a first guide section and a second guide element with a second guide section.
  • the first leadership section and the second guide section together form the guide area in the form of a closed contour in a top view of the guide device.
  • the proposed guide device can be cleaned more easily compared to the known guide devices.
  • the first guide element and the second guide element can be easily spaced apart in such a way that fewer fibers get stuck on the guide device.
  • the closed contour also prevents the fiber structure from jumping out of the guide area of the guide device or making other unwanted movements.
  • the guide device limits the freedom of movement of the fiber structure, particularly perpendicular to its direction of travel in a ring spinning machine. It is also conceivable that freedom of movement of the fiber structure in other directions is restricted by the guide device.
  • the closed contour of the guide area has the shape of a circle, an ellipse or a drop.
  • the contour of the guide area can be adapted in particular to the shape of the movement of the fiber structure, which it carries out through the guidance of the ring traveler. In this way, unnecessary friction of the fiber structure on the guide device and thus the detachment of additional fibers can be avoided.
  • the tension of the fiber structure can also be influenced by the shape of the contour of the guide area.
  • first guide element and the second guide element are arranged essentially parallel to one another. This contributes to further simplifying the threading of the fiber structure into the guide area of the guide device.
  • the first guide element and the second guide element can, for example, be plate-shaped.
  • the first guide element and the second guide element can in particular each be arranged in a plane, the planes being essentially parallel to one another.
  • the first guide element and the second guide element are arranged parallel to one another. It is conceivable that the first guide element and/or the second guide element comprise a plurality of flat sections, which in turn run parallel to one another.
  • first guide element and the second guide element are arranged one above the other when the guide device is used as intended.
  • the closed contour of the guide area can be constructively implemented in an efficient manner.
  • the first guide element and the second guide element are arranged one above the other in two parallel planes.
  • first guide element and the second guide element are connected to one another via a connecting section, the connecting section running perpendicular to the first guide element and the second guide element.
  • the connecting section increases the stability of the guide device. It is conceivable that during production the first guide element and the second guide element are initially produced as a common component, for example as a stamped part. The second guide element can then, for example, in a further manufacturing step from the plane of the first guide element be bent out and then aligned essentially parallel to the first guide element. The connecting section then results from the curved section between the first guide element and the second guide element. If the first guide element and the second guide element are provided as separate components, the connecting section can be formed, for example, by one or more connecting elements, such as screws, bolts or clamps.
  • the opening is at least partially formed by a distance between the first guide element and the second guide element. This contributes to further simplifying the threading process of the fiber structure into the guide area of the guide device.
  • the fiber structure In order to thread the fiber structure into the guide device, the fiber structure must be temporarily aligned along the opening, i.e. along the distance between the first guide element and the second guide element. If the first guide element and the second guide element are aligned parallel to one another, as described above, the fiber structure for threading must also be aligned essentially parallel to the two guide elements, for example.
  • the size of the distance between the first guide element and the second guide element can be selected such that automatic threading of the fiber structure into the guide area of the guide device is possible without any problems.
  • the first guide element has an entry area connected to the first guide section.
  • the fiber structure can be guided via the entry area when threading into the first guide section.
  • the entry area can, for example, be designed in the form of a channel with parallel side walls. He leads in particular from an outer edge of the first guide element to the first guide section, which is arranged, for example, essentially centrally between two outer edges of the first guide element. Depending on how the side walls of the entry area are spaced, the freedom of movement of the fiber structure when threading can be limited.
  • the entry area is at least partially formed by an arm which extends beyond the second guide element in the top view of the guide device.
  • the arm can be used, for example, to catch and fix the fiber structure when threading.
  • An outer edge of the arm can, for example, merge directly into one of the side walls of the entry area already described. This further simplifies the threading of the fiber structure first into the first guide section and then into the second guide section of the second guide element, in particular by a robot.
  • An exemplary threading process of the fiber structure into the guide area of the guide device can look like this.
  • the fiber bandage is brought into the area of the arm and captured by it.
  • the fiber structure is then moved in the direction of the first guide section.
  • the fiber structure moves along the arm and the entry area into the first guide section.
  • the fiber structure is at least partially aligned along the opening between the first and second guide elements.
  • the fiber structure can be brought into the second guide section of the second guide element, which completes the process.
  • first guide element and/or the second guide element are at least partially made as a stamped part, preferably Metal, is formed.
  • Metal is a robust and durable material.
  • the first and/or the second guide element can be smoothed after punching, for example by vibratory grinding. In particular, this rounds off the edges of the components so that damage to the fiber structure is less likely.
  • the first guide element and/or the second guide element can also be provided with one or more bends, particularly in the area of the edges. This can increase the stability of the components.
  • Various hardening processes for the stamped parts are also conceivable.
  • the first guide element and the second guide element can be produced, for example, as individual stamped parts. These are then assembled to form the guide device. As already mentioned, the first guide element and the second guide element can in particular also be produced as a single stamped part. The second guide element is then bent out of the plane of the first guide element, for example in a further method step, and preferably aligned essentially parallel to the first guide element.
  • the first guide element and/or the second guide element has a recess, the recess serving to fasten the guide device to a support of a workstation of a ring spinning machine.
  • the recess can be closed to the outside or open.
  • the recess serves to accommodate or pass through a screw, with the help of which the guide element is connected to the carrier can be connected.
  • the recess is not connected to the first guide section and the second guide section.
  • the ring spinning machine comprises at least one workstation for producing a yarn.
  • the workstation has a drafting system for stretching a fiber structure, a ring traveler rotating on a spinning ring and a guide device for guiding the fiber structure.
  • the guide device is designed according to the previous description.
  • the features mentioned can be implemented individually or in any combination.
  • the advantages described also result from the provision of the guide device according to the invention for the ring spinning machine. In particular, threading the fiber structure into the guide device and cleaning the guide device on the ring spinning machine are simplified.
  • the guide device is arranged between the drafting system and the spinning ring.
  • guidance of the fiber structure is particularly important in order to avoid damage to the fiber structure on the one hand and to control the tension of the fiber structure on the other hand.
  • the advantages of the guide device according to the invention therefore unfold in a special way in this area. It is conceivable that one or more balloon constriction rings are also arranged between the drafting system and the spinning ring in order to limit the expansion of the balloons of the fiber structure that may arise as a result of the rotation of the spinning ring.
  • the use of a guide device according to the previous description in a ring spinning machine is also proposed, wherein the ring spinning machine is designed in particular as described above.

  • the closed contour of the guide area 6 has the shape of a circle.
  • the contour of the guide area 6 can also have the shape of an ellipse or a drop, for example.
