Definitions
- the invention relates to a spinning station with a fiber guide element according to the preamble of patent claim 1.
- the present invention relates to the field of air spinning machines.
- Air spinning machines have a large number of spinning positions.
- a yarn is spun from a longitudinal fiber structure.
- the longitudinal fiber structure is first refined, that is, the amount of fibers per unit length is reduced by warping.
- the refined fiber structure is spun into a yarn in the spinning station.
- the spinning station has a fiber guiding element with a fiber guiding surface, which guides the fiber structure into a swirl chamber, where a yarn is produced in a spindle by the known vortex air spinning process.
- FIG. 1 shows a fiber guide element designed as a sleeve 3 with a fiber guide surface 5 arranged inside. A fiber structure 1 is guided through the sleeve 3 from the outlet roller pair 2 of the upstream drafting system.
- EP 1 335 050 A2 proposes a sleeve in which two mutually inclined fiber guide surfaces are arranged and thereby form a deflection point on the inside.
- the deflection point formed as an edge increases the proportion of the free fiber ends on the surface of the fiber structure by lifting them off. These free fiber ends are caught by the vortex flow in front of the spindle.
- the increase in the proportion of free fibers also increases the proportion of wrapping fibers in the yarn, and the quality of a yarn spun in this way can be improved.
- This deflection point improves the yarn quality, but it does nothing to improve the flow conditions when the fiber structure 1 enters the sleeve 3.
- the present invention is based on the object of specifying a spinning station with a fiber guide element and a fiber guide element, in which the flow conditions are also improved during the transition from the drafting system to the fiber guide element in order to subsequently obtain better conditions for spinning the fiber structure.
- the feed direction of the fiber structure to the direction of the fiber guide surface at a deflection point is inclined by an angle of inclination and that the deflection point is arranged inside or at the edge of the fiber guide element; this results in significantly improved flow conditions and, in particular, can effectively contain a wobble or pendulum movement of the fiber structure.
- the deflection point e.g. an entry edge can be on the edge of the fiber guide element, i.e. be arranged on the end face of the fiber guide element (see end face 33 from FIG. 2 described below), as well as by resetting or suitable positioning inside the fiber guide element.
- the invention leaves open how the exit of the fiber guide element can be designed. This can be done in accordance with the teaching of Scripture 1 335 050 A2. This configuration of the exit is not, however, necessarily prescribed by the invention.
- Figure 1 Representation of fiber guide element and pair of outlet rollers of a spinning station according to the prior art in EP 0 854 214 A2 and EP 1 335 050 A2.
- Figure 2 shows a sectional view of a fiber guide element according to the invention at a spinning station;
- FIG. 3 Compared to FIG. 2, a more detailed sectional illustration of a fiber guide element according to the invention.
- FIG. 1 to illustrate the problem and the solution provided by the present invention, a perspective view of a spinning station 6 of an air spinning machine with a pair of outlet rollers 2 and a fiber guide element 3 designed as a sleeve is shown. A fiber structure 1 is guided through the fiber guide element 3, which then in the spindle 7, not shown, to one
- the task of the fiber guide element 3 is to optimally feed the fiber structure 1 to the adjoining swirl chamber 36 so that a yarn can be formed there by means of an air flow.
- fiber guide element 3 and sleeve 3 are used synonymously.
- a fiber guide element 3 according to the invention is shown in FIG.
- the fiber structure 1 is transported in the direction 34 to the fiber guide element 3.
- a deflection is provided on the leading edge 32.
- the leading edge 32 is formed by an inclination between the feed direction 34 and the fiber guide surface 5 arranged in the sleeve 3 and is arranged inside said sleeve 3.
- an exit edge 17 is also provided in order to achieve an additional spreading of the edge fibers.
- a swirl stop 38 is provided at the end of the trailing edge 17.
- the present invention leaves open how the exit and the subsequent insertion into the inlet mouth 9 of the spindle 7 must be designed.
- an air inlet opening 37 is arranged in the swirl chamber 36.
- the leading edge 32 is based on the mostly cylindrical shape of the sleeve 3 and the distance b from the upper end face 33 of the sleeve 3.
- the entry ramp 39 is inclined by an angle ⁇ with respect to the fiber guide surface 5.
