Definitions

  • the invention relates to a method and a device for forming a wad of cotton as defined in the preamble of the first method and first device claim.
  • Cotton wraps serve as a template for the sweeping section and for the subsequent combing process.
  • the wadding rolls In order to obtain good results in the sweeping section, as well as in the combing process, it is essential that the wadding rolls not only have a uniform wad of wadding, but also that the winding density from roll to roll is essentially uniform.
  • the winding In order to obtain a sufficiently tight winding, the winding must be pressed against the winding rollers carrying the winding. This is done by exerting a force caused by appropriate means on the winding aid receiving the winding in the appropriate direction.
  • these winding tubes are held by axles inserted at both ends of the tube.
  • a second way of exerting the above-mentioned force on the axles is to use toothed racks instead of compressed air cylinders, which are connected to the axle bearings guided in sliding guides and which, by means of a toothed wheel overdrive engaging the toothed racks, cause the force corresponding to the pressure cylinders.
  • These arrangements have the disadvantage that, due to the contact force acting uniformly over the entire time of the winding formation, the winding experience a decreasing pressing force as a result of the increasing contact surface, which causes a continuously decreasing density of the winding. According to the invention, this disadvantage is eliminated by the steps described in the characterizing part of the first method claim and by the means defined in the characterizing part of the first device claim.
  • the further advantageous embodiments are described in the additional claims.
  • the advantage achieved by the invention consists in the uniform contact pressure of each layer during the construction of the cotton roll.
  • a device 1 for forming a cotton roll (identified by the reference numerals LM and N in FIG. 3) on a winding tube 2 comprises two winding rollers 3 and 4 (respectively, only one shown in FIG Side walls 5 and 6 of the device 1 are rotatably mounted (not shown) and can be driven. 2, the rotatability of the winding rollers 3 and 4 with the geometric axis of rotation 4.1 of the winding roller 4 is only indicated for the sake of simplicity.
  • the winding tube 2 lying thereon is set in rotation and thereby takes the wadding emitted by the calender rollers 7 web 8 to form the cotton roll.
  • the winding tube 2 is held on both sides by a piston 9 of a pneumatic cylinder 10 which engages in the winding tube and which thereby form the axes which receive the winding tube 2.
  • Each pneumatic cylinder 10 is in turn attached to a support arm 11.
  • a disk 39 guiding the cotton roll is provided coaxially with the piston 9.
  • the disks 39 are each rotatably arranged by means of a roller bearing 40 which is accommodated in a bearing housing 41 belonging to the support arm 11.
  • the support arms 11 provided on both sides of the winding rollers 3 and 4 are each pivotally connected at the upper end to a slide guide 12 and at the lower end to a pivot mechanism 13.
  • the slide guide 12 comprises a slide rail 14 which is held at both ends by a carrier 15 or 16. These supports 15 and 16 are fastened on the one hand to the side wall 5 and on the other hand to the side calf 6.
  • the slide rail 14 serves to receive a slide element 17, on which the support arm 11 is pivotally connected by means of a hinge 18.
  • a control ruler 19 is also pivotally attached to the sliding element by means of a hinge 20.
  • the control ruler 19 has a control surface 21, by means of which a commercially available pressure reducing valve 22 known per se is controlled.
  • the pressure reducing valve 22 is also slidably attached to a support belonging to the side wall 5 (not shown) with the aid of an associated holder 26 provided with a slot 25.
  • the pressure reducing valve 22 is fed by a compressed air source 27 and forwards an air pressure adapted to the requirements by means of a compressed air line 29 to a pneumatic cylinder 28 which can be acted upon on both sides.
  • the compressed air cylinder 28 is on the one hand pivotally attached to a stationary support 30 belonging to the device 1.
  • a piston head 32 belonging to the piston 31 of the cylinder 28 is also pivotally connected to a lever 33 belonging to the pivot mechanism 13.
  • the lever 33 in turn is part of an intermediate piece 34 which is provided with a flange 35 at both ends.
  • the pivot mechanism is pivotally connected on the one hand by means of an axis 36 to a bearing element 37 firmly anchored in the side wall 5 or 6, and on the other hand by means of a pivot pin 38 to the support arm 11.
  • the position of the swivel mechanism 13 is such that when the support arm 11 is raised in the direction H (FIG. 1) from the lowest position of the support arm 11 shown in FIG. 1 to a top position (not shown), the swivel mechanism 13 from the one with the angle limiting line A marked position in the position marked with the angle limit line B. Location pivots.
  • the wire boundary line A lies in an imaginary plane containing the geometric axis of rotation of the axis 36 and the pivot pin 38, and these two lines A and B also limit the angle ⁇ .
  • the position of the swivel mechanism 13 is further characterized in that the line C bisecting the angle ⁇ intersects the axis of symmetry S of the support arm 11 in the lowest position, with a right angle or in other words, with an angle of 90 degrees, that the axis of symmetry of the support arm 11 located in the lowest position coincides with the axis of symmetry of the support arm 11 located in the uppermost position. It should also be mentioned that in the lowest position of the support arm 11, the winding tube 2 and in the uppermost position of the support arm 11, the full winding (marked N in FIG. 3) rests on the winding rollers 3 and 4.
  • the principle applies that the surface pressure in the contact surfaces between the winding K - N to be built up (FIG. 3) and the winding rollers 3 and 4 should take a controlled course.
  • FIG. 3 shows the winding rollers 3 and 4 with the winding tube 2 and indicates with the circles L, M, N the growing cotton roll.
  • FIG. 3 shows, on the right half labeled R, that is to the right of the direction of force F of the support arms 11, force ratios provided that the force F is maintained throughout The winding structure remains constant, which is shown by the force arrows FG of the same length.
  • the force FG is half of the force exerted by both support arms, which also corresponds to the force exerted by one support arm.
  • the contact force FK to FN decreases with increasing winding diameter from K to N. 3, the contact force is to be understood as the force which arises in the contact surface of the sleeve 2 or the winding on the winding roller 4.
  • the force curve of the forces FK to FN is shown in FIG. 4 with the characteristic curve FK-N and the force curve of the forces Fl to F4 with the characteristic curve Fl - 4, the ordinate showing the force F and the abscissa of the winding diameter.
  • the characteristic curve Fl - 4 takes into account that the contact forces should remain constant despite the winding becoming larger, but not yet that the surface pressure between the windings of different diameters and the winding roller should remain constant.
  • the surface pressure also called specific surface load, measured in Newtons / m2, called
  • the force F In order to keep the surface pressure constant even when the contact surface increases, the force F must be adjusted, which is indicated by the characteristic curve FA.
  • the air pressure delivered to the compressed air cylinder 28 In order to achieve the force curve of the force F shown with the characteristic curve FA, the air pressure delivered to the compressed air cylinder 28 must be correspondingly controlled by means of the control ruler 19 or by means of the control surface 21, as shown in FIG. H. the control surface 21 is shaped accordingly.
  • This control surface 21 must also contain the correction which compensates for the change in the force effect of the pneumatic cylinder caused by the pivoting movement of the lever 33 and the pivot mechanism 13.
  • control surface 21 Since the change in the contact surface is from the machine construction. dependent experience, the shape of the control surface 21 must be determined by experiment.
  • the control ruler can be pivoted by means of the hinge 20 and held by means of the screws 22 and fixable, as already mentioned.
  • the position of the pressure reducing valve 22 must also accordingly are changed, which is possible with the manner of fastening the pressure reducing valve 22, which includes the slot 25.
  • the compressed air cylinder 28 is connected at the end facing the piston 31 to a so-called 3/2-way valve 42 (with a blocking zero position), which is in the zero position shown in FIG. 1 during the winding construction.
  • the support arms 11 are lifted in the direction H due to the increasing winding diameter, whereby the piston 31 is pushed into the compressed air cylinder 28.
  • This pushing in builds up an air pressure in the part of the cylinder 28 connected to the compressed air line 29, which air pressure may or should have a certain size depending on the desired contact force FA. If, for example, the air pressure requirement corresponding to the greatest contact force FA is smaller than the air pressure built up by the movement of the piston 31, the controlled pressure reducing valve 22 must relieve the pressure in the compressed air line 29 via a vent 43 belonging to the pressure reducing valve 22.
  • the 3/2-way valve 42 is switched over, so that the full pressure of the compressed air source, e.g. B. 10 bar, pushes the piston 31 all the way into its final position in the compressed air cylinder 28.
  • the support arms 11 are in a not essential to the invention and therefore not described Brought intermediate position in which the sleeve 2 placed on the winding roller 3 and 4 can be gripped by the piston 9 pushed into the new sleeve 2 without any contact force FA.
