Definitions

  • the invention relates to a combing machine according to the preamble of patent claim 1.
  • combing machines are known for example from FR-A-2 264 899.
  • the combing suction shaft primarily serves to discharge the combs pneumatically. Combs are combed out from the fiber whiskers by the round comb segment and usually by a fixed comb from the fiber whiskers, which are torn off by the tear-off cylinder and the tear-off pressure roller from the cotton lying in the forceps aggregate.
  • the air flow sucked between the tear-off cylinder and the pliers unit into the combing suction shaft has the desired effect of laying the fleece end sections fed back by the tear-off cylinder down on the circumference of the tear-off cylinder, so that combed fiber fibers that come from the pliers unit to the tear-off cylinder can be smoothly placed on the fleece end sections in order to then be soldered to them.
  • this desired effect often does not occur to the extent necessary.
  • Air currents caused by the rotating round comb shaft and the rotating round comb brush in the combing suction shaft also have a disruptive effect. In particular, a pressure surge occurs in the Kämmlings extraction shaft under the tear-off cylinder each time the circular comb segment enters the circular comb brush.
  • the object of the invention is to design the combing machine specified at the outset in such a way that a sufficient laying down of the fed-back nonwoven end sections on the circumference of the tear-off cylinder can be ensured without disruptive influence on the fiber whiskers moving from the forceps unit to the tear-off cylinder.
  • the additional suction air shaft has an upper inlet opening, which is arranged in the tear-off cylinder in such a way that air sucked into the inlet opening causes a tangential air flow at the tear-off cylinder, which causes each fleece end section fed back by the tear-off cylinder via a Apply an angle of at least 180 °, measured from the nip between the tear-off cylinder and the tear-off pressure roller, to the circumference of the tear-off cylinder.
  • the additional suction air duct is connected to a suitable vacuum source. It is easiest if the additional suction air shaft communicates with the combing suction shaft, in which there is a negative pressure anyway during operation, at a point below the circular comb brush. If the additional suction air shaft above this point is separated from the combing suction shaft in which the round comb shaft and the round comb brush rotate, there is a uniform, practically non-pulsating flow in the additional suction air shaft and along the tear-off cylinder, with which the returned fleece end sections reliably come into contact the circumference of the tear-off cylinder can be created. Moreover, the uniform suction air flow also ensures that the soldering area is kept clean of dust and impurities more effectively than is possible with a pulsating flow.
  • the fed-back nonwoven end sections are applied to the circumference of the tear-off cylinder through an angle of at least 180 ° by the air flow, which is sucked forward into the additional suction duct through the upper edge of the front wall of the combing duct .
  • a combing machine contains a forceps unit with a forceps frame 1, which can be moved back and forth by forceps cranks 2, which are articulated at its rear end, between the illustrated front end position and a rear end position.
  • front supports 3 are articulated, which can be pivoted about the axis of a round comb shaft 4 are.
  • the pliers unit includes a lower pliers plate 5 carried by the pliers frame 1 and an upper pliers plate 6 which is carried by upper pliers arms 7 which are pivotally connected to the pliers frame 1 about an axis 8.
  • a cotton wool W to be combed is clamped between the front edge of the lower forceps plate 5 and the lower edge of the upper forceps plate 6, and a fiber beard protruding from the forceps unit is combed out by a circular comb segment 9, which is carried on the rotating round comb shaft 4 is.
  • the front edge of the lower pliers plate 5 and the lower edge of the upper pliers plate 6 thus form a clamping area for clamping the cotton wool W to be combed.
  • a tear-off cylinder 10 is mounted in the frame of the combing machine at a point which lies just before the front edge of the lower jaw plate 5 when the forceps unit is in its front end position shown.
  • a tear-off pressure roller 11 interacts with the tear-off cylinder 10 and presses a combing machine fleece V made of combed fiber material against the tear-off cylinder 10.
  • the tear-off cylinder 10 and the tear-off pressure roller 11 are rotated back and forth with a pilgrim step movement. During the reverse rotation, they feed back an end section V.1 of the fleece V, so that a combed fiber beard W.1, which is moved from the pliers assembly to the tear-off cylinder 10, can lie on the fleece end section V.1.
  • the tear-off cylinder 10 and the tear-off pressure roller 11 are rotated forward and pull the fleece end section V.1 together with the fiber beard W.1 placed thereon, which has been pushed forward by a predetermined amount of food with respect to the tongs unit, back into its clamping line, the Tip of the fiber beard W.1 is torn off from the cotton wool W lying in the pliers unit.
  • the fibers of the fiber beard W.1 captured by the tear-off cylinder 10 are generally pulled through a fixed comb (not shown).
  • a combing duct 12 is arranged in the usual way.
  • the round comb shaft 4, which carries the round comb segment 9, and a round comb brush 13 extend transversely through the combing suction shaft 12.
  • a front wall 14 of the shaft 12 has an upper edge which runs adjacent to the tear-off cylinder 10.
  • a rear wall 15 of the shaft 12 has an upper edge which runs adjacent to the path of movement of the circular comb segment 9.
  • An adjustable throttle plate 17 extends into the connecting piece 16. The size of the extracted air flow can be regulated by moving the throttle plate 17.
  • An additional suction air shaft 18 is arranged in front of the combing suction shaft 12 and communicates with the combing suction shaft 12 at a location below the round comb brush 13.
  • the lower end of the additional suction air shaft 18 opens between the round comb brush 13 and the nozzle 16 in the combing suction shaft 12.
  • Periodic turbulent air flows or pressure fluctuations caused by the rotation of the round comb shaft 4 and the round comb brush therefore only influence the air flow through the additional suction air shaft 18 insignificant.
  • an adjustable throttle plate 19 extends. By moving the throttle plate 19, the width of a slot 20, which is delimited by an edge of the throttle plate 19 and a wall opposite this edge, and thus the size of the air flow by the additional Regulate suction duct 18.
  • the additional suction air shaft 18 is expediently limited, as shown, on the one hand by the front wall 14 of the combing suction shaft 12 and on the other hand by an additional front wall 21.
  • the front wall 21 can also contain a slot 22 through which some air can pass can be sucked from the environment in the lower region of the additional suction duct 18.
  • the slot 22 can be limited by an adjustable plate 23, the displacement of which allows the width of the slot 22 and thus the proportion of the air drawn in from the environment to be regulated.
  • the additional suction air shaft 18 has an upper inlet opening 18.1, which runs adjacent to the circumference of the tear-off cylinder 10 in such a way that the air flow, which is sucked forward between the upper edge of the front wall 14 and the circumference of the tear-off cylinder 10, into the additional suction air shaft 18, each Fleece end section V.1 fed back from the tear-off cylinder 10 is sucked around the rear of the tear-off cylinder 10 and applied to the circumference of the tear-off cylinder 10 over an angle of more than 180 °, measured from the clamping line between the tear-off cylinder 10 and the tear-off pressure roller 11.
  • the half-plane starting from the axis of the tear-off cylinder 10 and containing the axis of the tear-off pressure roller 11 (and the clamping line) forms with the half-plane starting from the axis of the tear-off cylinder 10, which is the narrowest point of the passage gap between the tear-off cylinder 10 and the contains the upper edge of the front wall 14, an angle measured at the rear around the tear-off cylinder 10 of more than 180 °.
