Definitions

  • the invention relates to a combing machine with a rotatable circular comb roller, which carries at least one circular comb segment and at least one tear-off segment, which cooperates with a tear-off pressure cylinder, and with a pair of pliers which has a pair of lower pliers which are stationary with respect to the axis of the circular comb roller and a pair of upper pliers which can be moved with respect to the lower pliers .
  • the object of the invention is to design the specified combing machine in such a way that it can be produced simply and inexpensively and thereby enables high production (amount of fibers per unit of time).
  • the combing machine according to the invention is characterized by a device for sucking in fibers torn off by the tear-off segment and the tear-off pressure cylinder.
  • the separate tear-off cylinder which is present in known combing machines and the pressure roller which cooperate with it and which are rotated with a pilgrim step movement can first be dispensed with.
  • the device can contain a suction shaft with an inlet opening adjacent to the tear-off pressure cylinder. In this way, however, you do not get a sliver, but individual tufts of fibers - the machine acts practically as a stack sorting machine.
  • the device for sucking fibers can also contain a screen drum adjacent to the tear-off pressure cylinder, the interior of which can be connected to a vacuum source. With such a screening drum it is possible to produce a combed belt.
  • the fixed comb used in known combing machines is dispensed with, that is to say if there is a free space without additional combing elements between the lower pliers and the tear-off pressure cylinder when the pliers unit is open.
  • a decrease in the quality of the comb is accepted. This decrease can be kept within limits if the pliers unit has additional pliers which can be moved with respect to the lower pliers in order to clamp this cotton onto the lower pliers during the tearing off of fibers from a cotton fed to the lower pliers.
  • the pliers unit can also contain a rotatable cotton pressure cylinder for pressing a cotton to be combed onto the lower pliers.
  • the combing machine shown schematically in FIG. 1 has a continuously rotatable round comb roller 1, which carries a round comb segment 2 and a tear-off segment 3, which cooperates with a tear-off pressure cylinder 4.
  • the circular comb roller 1 could also carry several circular comb segments and several tear-off segments.
  • the combing machine also has a pair of pliers which has lower pliers 5 which are fixed with respect to the axis of the circular comb roller 1 and upper pliers 6.
  • the upper pliers 6 can be moved with respect to the lower pliers 5 in order to clamp a fiber beard between the front edge of the lower pliers 5 and the lower edge of the upper pliers 6, which is then combed out by the circular comb segment 2 passing under the lower pliers 5.
  • the combing machine also includes a suction shaft 10 connected to a vacuum source (not shown) with an inlet opening 10a adjacent to the tear-off pressure cylinder 4 and a cleaning brush with a brush roller 11. It may be expedient to brush brush roller 11 only on part of its circumference with a brush segment 12 to be provided so that the brush segment 12 only interacts with the circular comb segment 2 and does not damage the tear-off segment 3.
  • the pliers assembly 5, 6 is closed and holds a fiber beard from the cotton wool W supplied to the circular comb segment.
  • the tongs unit 5, 6 opens.
  • the intermittently rotatable feed cylinder 7 can now advance the cotton wool W on the lower tongs 5 by an adjustable amount.
  • the additional pliers 9 are lowered against the lower pliers 5 as shown, in order to keep the cotton wool W clamped onto the lower pliers 5 shortly behind the front edge during the subsequent tearing off.
  • the fiber beard comes to the tear-off segment 3, approximately in the position of the circular comb roller 1 shown to lie and is lifted by this and clamped against the tear-off pressure cylinder 4.
  • the fibers clamped between it and the tear-off pressure cylinder 4 are then torn off.
  • the torn fibers are sucked into the suction shaft 10.
  • the tear-off pressure cylinder 4 can be rotated by the movement of the tear-off segment 3, but it can also have its own rotary drive.
  • the additional pliers 9 are lifted off the lower pliers 5 again.
  • the feed cylinder 7 can then advance the cotton wool W on the pliers 5 again by an adjustable amount. This second advancement is optional if advancement has already been carried out before tearing off.
  • the fibers sucked off through the suction shaft 10 are in the form of tufts of fibers which have been freed of impurities and short fibers by combing them out.
  • the machine works practically as a stack sorting machine. With the tufts of fibers, for example, a band can then be formed again on a card.
  • the machine is simple and constructed with few moving parts, which makes it not only inexpensive, but also enables high working speeds.
  • high production is also possible in that between the front edge of the lower pliers 5 and the tear-off pressure cylinder 4, when the upper pliers 6 are lifted off the lower pliers 5, a free space without additional combing elements, i.e. without the usual fixed comb. Therefore, a thicker wadding W can be fed to the machine.
  • FIG. 1 show various possible variants of the combing machine according to the invention, wherein same parts with the same reference numerals as in Fig. 1 are designated.
  • the additional pliers 9 shown in FIG. 1 are omitted and replaced by a small rotatable cotton pressure cylinder 13, which is mounted on the lower pliers 5 as close as possible to the front edge thereof.
  • the cotton pressure cylinder 13, which presses the cotton wool W to be combed onto the pliers 5, is driven by a drive device (not shown), in which a freewheel is arranged, each time the feed cylinder 7 is rotated.
  • the suction shaft 10 shown in FIG. 1 is omitted and replaced by a rotatable screen drum 14 which is adjacent to the tear-off pressure cylinder 4 and which sucks in the fibers torn off by the tear-off segment 3 and the tear-off pressure cylinder 4.
  • the screening drum 14, the interior of which is connected to a vacuum source (not shown), has an air-permeable jacket which is covered on the inside in an upper region of the circumference by a stationary, non-air-permeable shield 15. The negative pressure therefore acts only in a lower region of the circumference, on which the sucked fibers are transported to a pair of press rollers 16 connected by the rotation of the screen drum 14.
  • the screening drum 14 is rotated by a drive device (not shown) either continuously or step by step or with a vocational step movement. If a suitable drive device ensures that the tufts of fibers torn off one after the other by the tear-off segment 3 and the tear-off pressure cylinder 4 overlap somewhat on the screen drum 14, a tape can be obtained directly in the variant according to FIG. 3, together with the press roller pair 16 . It is also possible, however, to transport the tufts of fibers separately from one another on the screening drum 14 and to connect them to a band only in the pair of press rollers 16 by the Press roller pair is rotated with a vocational step movement.
  • FIG. 4 differs from that of FIG. 3 only in that the screen drum 14 is rotated in the opposite direction and that a stationary, not air-permeable cover 15 'covers the jacket of the screen drum 14 in a lower region of the circumference inside .
  • the negative pressure therefore only acts in an upper region of the circumference of the screen drum 14, and the sucked-in fibers are carried to the press roller pair 16 on this upper region of the circumference. Otherwise, the mode of operation is the same as described for the variant according to FIG. 3.
  • the cotton pressure element is omitted in the variant according to FIG. 5.
  • a fixed comb 18 is attached to the pliers 5, which are movable with respect to the same, for example on levers 17 which can be pivoted about the axis of the feed cylinder 7.
  • this fixed comb 18 is kept lowered in the position shown onto the lower pliers 5 during the tearing off of fibers in order to comb out the rear ends of the tufts of fibers torn off the wadding W.
  • a groove 20 is provided just behind its front edge, which receives the free ends of the fixed comb needles so that they can extend all the way through the wadding W.
  • the fixed comb 18 is lifted off the lower pliers 5.
  • a fixed comb 19 can be arranged movably on the upper pliers 6 according to FIG. 6.
  • the fixed comb 19 is in the illustrated lower position during the tearing off of fibers in order to comb out the rear ends of the tufts of fibers torn off from the cotton wool W. In the remaining time, the fixed comb 19 is retracted upward with respect to the upper pliers 6.
  • the cotton pressure element is not shown in FIG. 6, but either the additional pliers 9 according to FIG. 1 or the cotton pressure cylinder 13 according to FIG. 2 is again present.
