Definitions

  • the invention relates to a balloon limiter for a textile machine according to the preamble of claim 1.
  • balloon limiters are used to narrow the formed by the running thread circulating thread balloon. Also on winding machines, the balloon behavior of the yarn withdrawn from the cop is influenced by means of the balloon limiter and the thread tension is kept low.
  • balloon limiters allows a reduction in the distance, referred to as spindle pitch, from spindle center to spindle center. In this way, more spindles can be arranged on a textile machine without lengthening the machine.
  • DE 1510869 A shows a balloon limiter whose cylindrical jacket is formed by a ring.
  • the holder is made by solid patches that surround the balloon limiter on the entire circumference. The patches are each attached to one of two spaced running longitudinal profile carriers. This bracket is expensive.
  • the ring has to protect its position Umkantungen that prevent falling out of the filler. Such rings are made by forming processes such as extrusion or by welding.
  • the balloon restrictor according to the invention only a small amount of material that is easy to process is required. Despite its low weight, it provides good dimensional stability. This stability is achievable when at the two edges of the hollow cylinder in each case an edge strip is folded.
  • the width of the Umfalzung between 5 mm and 10 mm.
  • the sheet thickness of the metal strip from which the hollow cylinder is made is advantageously between 0.3 mm and 0.6 mm. This sheet thickness represents an optimum between low weight and dimensional stability.
  • a further increase in the stability of the cylindrical shape of the hollow cylinder can be achieved by bent at right angles to the outside end portions of the metal strip, which are pressed against each other.
  • the balloon limiter is designed in such a way that the end sections touch a frame wall of the textile machine and an electrically conductive connection is established by the contact, the undesired electrostatic charge of the balloon limiter caused by friction of the running thread on the hollow cylinder is dissipated.
  • the balloon limiter is preferably held by means of a holding element which presses the end sections against one another. Includes the holding element first planar contact surfaces with which it rests against the end portions and presses against each other, and at least a second concave contact surface, with which it rests against the outer surface of the cylinder, and the balloon limiter is fixed by means of connecting elements, the holding element and traverse the end portions, undergoes an inventive hollow cylinder additional stabilization.
  • the second contact surface, with which the holding element bears against the outer surface of the hollow cylinder is adapted to the curvature of the hollow cylinder.
  • the balloon limiter obtains a secure fit in the retaining element.
  • the holding element on position cam and holding magnets, with which it can be fixed to a frame wall of the textile machine.
  • the position cams of the holding element engage in corresponding position holes of the frame wall of the textile machine and allow fast and accurate positioning.
  • the holding magnets which are firmly connected to the holding element, together with the position cam ensure a secure fit of the balloon limiter.
  • the magnetic connection is easily solvable if necessary and without the use of tools.
  • the holding element made of plastic.
  • An embodiment of the retaining element made of plastic has little weight.
  • the holding element can be produced particularly inexpensively, for example as an injection molded part.
  • the hollow cylinder is made of thin stainless chromium-nickel steel, the wear resistance is high even without additional surface treatment.

  • FIG. 8 shows the balloon limiter of FIG. 7 in the view C, FIG.
  • FIG. 9 shows the detail X of FIG. 7.
  • Figures 1, 2 and 3 show a balloon limiter 1 for a textile machine with a hollow cylinder 2.
  • the hollow cylinder 2 is formed from a sheet metal strip.
  • the length of the metal strip is greater than the circumference of the hollow cylinder 2.
  • an edge strip 8, 9 is folded in each case.
  • the edge strip 8, 9 may have a width b of 5 mm to 10 mm.
  • An end section 3, 4 is formed at each of the two ends of the sheet metal strip from the longitudinal section of the sheet-metal strip extending beyond the circumference.
  • the two end portions 3, 4 are the same length, bent at right angles outwards and pressed against each other.
  • the end sections 3, 4 are both compressed by rivets 5 as well as firmly connected to an angled flap 6 of the frame wall 7 of the textile machine.
  • the hollow cylinder (2) is held in a simple manner by the outwardly bent end portions (3, 4) of the sheet metal strip.
  • the thin sheet metal strip may consist of a chromium-nickel sheet or of an aluminum sheet on which a wear-reducing surface treatment has been made.
  • the balloon limiter 1 is inexpensive to manufacture and easy to assemble. Additional brackets are not needed.

  • a simple screw connection includes, for example, a screw with nut.
  • the sections 18, 19 are in each case with a first planar contact surface 21, 22 at the end portions 14, 15 at.
  • the pressing pressure, by which the end portions 14, 15 are pressed against each other, is generated by tightening the screw 20.
  • the sections 18, 19 of the retaining element 13 are located on the hollow cylinder 23, each with a concave second contact surface 24, 25.
  • the curvature of the concave contact surfaces 24, 25 is adapted to the curvature of the hollow cylinder 23.
  • the hollow cylinder 23 and the holding member 13 have the same height.

  • the projection a of the end sections 14, 15 ensures that the end sections 14, 15 are in contact with the frame wall 32 and an electrically conductive connection is made between the hollow cylinder 23 and frame wall 32.
  • the electrostatic charge which results from the friction of the rotating thread in the hollow cylinder 23, safe dissipated.

Abstract

La présente invention concerne un limiteur de ballon (12) pour une machine textile, comprenant un cylindre creux métallique (23) qui présente une surface résistante à l'usure, formée d'une bande de tôle. Une bande latérale (8, 9; 10, 11; 55, 56) est respectivement repliée sur le bord supérieur et le bord inférieur du cylindre creux (2, 23, 37). Une section d'extrémité (14, 15) est respectivement pliée vers l'extérieur aux deux extrémités de la bande de tôle et le cylindre creux (2, 23, 37) est maintenu par les sections d'extrémité (3, 4; 14, 15; 38, 39). L'épaisseur de tôle de la bande de tôle (23) est inférieure ou égale à 0,6 mm. Il est ainsi possible de fabriquer un cylindre creux indéformable (23) de manière simple et économique. La stabilité dimensionnelle du cylindre creux (23) est renforcée par l'élément de maintien (13) du limiteur de ballon (12).
