Definitions

  • the invention relates to a spinning machine with a plurality of spinning stations according to the preamble of claim 1 and a method for yarn production according to claim 9.
  • a spinning machine with such spinning stations is known for example from DE-A-39 09 373.
  • the spinning station described there consists of a bell-shaped cover which can be driven in rotation by means of an air stream.
  • the spindle which can be moved up and down inside the bell, is driven by a running belt.
  • a ring with a rotor running around it in the manner of a ring spinning machine is provided on the lower edge of the bell.
  • the object of the invention is now to develop a spinning station with a bell and, at the same time, to provide a yarn production process which enables substantially lower and selectable thread tensions at high speeds of the bell.
  • the invention is based on the essential knowledge that not only a relative movement between the bell and a thread guide element at the end of the bell is necessary, but that this relative movement must be reliably adjustable. This requires very little friction, which is independent of centrifugal forces that arise when the bell is turned high. Since the speed of the bell is lower than the speed of the spindle, the speed of the tire lies between these two speeds. This relatively higher rotational speed of the tire compared to the rotational speed of the bell can be easily adjusted by a suitable selection of the rotational speeds of the bell and the spindle. The size of the thread tension can thus also be set, since the bearing friction, which mainly determines the thread tension, is essentially proportional to the relative speed of rotation of the tire. As in normal operation, the conditions can easily be guaranteed when starting up or braking the spinning station.
  • the invention has the great advantage that the element for the relative rotation with respect to the bell has a very long service life and therefore does not have to be replaced or hardly needs to be replaced during operation.
  • FIG. 1 shows a spinning machine with an apron warping zone 1, a pair of draw-off rollers 2 and a bell 4 driven around a spindle 3. Between the pair of draw-off rollers 2 and the bell 4, a thread guide 5 designed as a swab tail is provided.
  • the bell 4 is rotatably mounted with a bell bearing 6, a ball bearing and is driven by a drive 7, which can be a frequency-controlled asynchronous motor or an air motor, at a predetermined speed n G.
  • the conically widened end 8 of the bell 4 is rotatably connected to a ring 10 provided below it via a roller bearing 9.
  • An eyelet 11 is provided on the inner wall of this tire 10 and serves as a guide element for the thread 12.
  • the guide element can also have the shape of an obliquely upward slit with a circular end, as is generally known for the bell of a conventional spinning station (see, for example, EP-A-0303 063).
  • the thread 12 formed in the spinning station is wound onto a bobbin 13 which is attached to the spindle 3.
  • the essential differences here are the relative differences between the speed n G of the bell 4, the speed n F of the thread guide element or the eyelet 11 and the speed n S of the spindle 3.
  • the speed difference n can be set by changing or controlling the frequency of the AC voltages applied. But even if the bell 4 is air-driven, the speed difference n can be set easily.
  • the speed n G of the bell 4 must first be determined as a function of the air flow speed. It is important that the speed n S of the spindle 3 is always greater than the speed n G of the bell 4, and that the speed n F of the thread guide element 11 is also always greater than the speed n G of the bell 4, but always less than the speed n S of the spindle 3.
  • the plain bearing consists essentially of a round, curved edge of the tire 10 and a hollow circular groove in the lower edge of the conical end 8 of the bell.
  • the tire 10 with its convex rim consists of a material suitable for slide bearings, advantageously of a polyimide material with a small proportion of graphite and Teflon fluorocarbon resin, which is known as type SP-211 from DuPont, USA. The physical properties of this material are known from the brochure "VESPEL” E-65290-02 (published in November 1989).
  • FIGS. 6 and 7 show further variants of a sliding bearing 15, the bell with its conically widened end and the tire 10 being made from a common metal such as aluminum.
  • the tire 10 has a rectangular bulge 16 and the conically widened end 8 of the bell has a slide piece 17 connected to it in one piece.
  • This slider 17 is in turn made of a suitable material for sliding bearings, such as the aforementioned polyimide material, and is provided to match the bulge 16.
