Definitions

  • the invention relates to a combing machine with at least one combing head, which contains a vibrating pliers unit, in which an intermittently rotatable feed cylinder for advancing the cotton to be combed in the combing head is mounted.
  • the feed cylinder is driven by the opening or closing movement of the tongs unit consisting of the lower tongs and upper tongs, i.e. on the relative movement of the upper tongs with respect to the lower tongs, while the pliers assembly swings between a retracted, closed position and an advanced, open position.
  • the drive takes place during the forward movement of the pliers unit - so-called forward feed - or during the return movement of the pliers unit - so-called return feed.
  • a switch from flow feed to return feed or vice versa is possible with some designs, but also cumbersome.
  • the object of the invention is to avoid these disadvantages.
  • the object is achieved in the combing machine specified in the introduction in that an electric motor is arranged for the intermittent rotation of the feed cylinder.
  • the electric motor driving the feed cylinder for example a stepper motor or servo motor, can easily be controlled with a simple control device so that it rotates the feed cylinder through a desired angle during each forward movement or during each return movement of the forceps unit.
  • the feed cylinder can also, if desired during the forward movement as well as during the return movement - so-called mixed feed.
  • the feed amount i.e. the angle of rotation during each comb play, can be changed in a simple manner and without loss of time, even when the combing machine is running, if desired continuously, if the lengths and / or amplitudes and / or (in the case of a stepper motor) numbers of the the drive pulses feeding the electric motor are adjustable.
  • these drive impulses have to be synchronized with the movements of the pliers unit, that is, they always occur at the same time or in the same times during each comb game.
  • the position of this point in time or these points in time in the comb play can also be changed in a simple manner if the phases of the drive pulses with respect to the movements of the pliers unit can be set in the control device.
  • the feed cylinder is rotated by an adjustable angle at an adjustable time during the forward movement of the forceps unit and / or at an adjustable time during the return movement.
  • the control device can therefore preferably be designed such that it not only controls the electric motor of the feed cylinder, but also a drive device for a continuously rotating winding roller, which unwinds the cotton to be combed in the combing head from a cotton roll.
  • the circumferential speed of the winding roller should be such that the wad length unwound from the wadding roll is always approximately in the same ratio during a comb game to the wad length advanced by the feed cylinder in the comb game.
  • a sensor can be arranged according to the invention, which continuously detects the titer of the combed strip emitted by the combing head and outputs it as a control variable to a controller which adjusts the amount of food to keep the titer at least approximately constant.
  • a sensor can also be arranged in such a way that it determines the titer of the combed strips emitted by the combing heads and combined or doubled with one another, optionally after being warped in a drafting system.
  • the assigned controller can then adjust the feed amounts for all combing heads together.
  • the feed roller can be assigned its own electric motor in each combing head. All or at least some of the electric motors can be supplied by a common control device, or a separate control device can be assigned to each electric motor. However, it is also possible to couple the feed rollers of at least some of the combing heads with one another and to drive them with a common electric motor. In such a case, a sensor would of course be recommended for a control system, which detects the titer of the combing belts emitted by the coupled combing heads and combined with one another.
  • the combing head according to FIG. 1 has in the usual way two winding rollers 1 and 2, a pliers shaft 3, a round comb shaft, 4, a first tear-off cylinder pair 5, a second tear-off cylinder pair 6 and a discharge roller pair 7, all of which are mounted in a machine frame (not shown).
  • a cotton roll 8 rests on the two rotatable winding rollers 1 and 2.
  • the oscillating pliers shaft 3 carries crank arms 9 to which the rear end of lower pliers 10 is articulated.
  • the front end of the collet 10 is articulated on front supports 11 which are pivotally mounted about the round comb shaft 4.
  • Upper pliers 12 are connected to lower pliers 10 so that they can pivot about pins 13.
  • the pliers assembly 10, 12 is in the forward position of the lower pliers 10 open while it is closed in the rear position.
  • An intermittently rotatable feed cylinder 14 is mounted in the tongs 10.
  • the continuously rotating round comb shaft 4 carries in the usual way a round comb roller 15 with a round comb segment 16 carrying comb teeth.
  • the cotton wool W unwound from the cotton roll 8 by the rotation of the winding rollers 1, 2 runs to the feed cylinder 14 and from there into the clamping point of the forceps unit 10, 12.
  • the closed forceps unit 10 holds , 12 the rotating circular comb 15, 16 a fiber beard from the cotton wool, which is combed out by the circular comb segment 16.
  • the lower pliers 10 are moved into their front position and the pliers assembly 10, 12 is opened.
  • the combed fiber beard is pulled through a fixed comb, not shown, into the tear-off cylinder pair 5 and is united therein with the previously combed cotton wool.
  • the pliers unit 10, 12 is then moved back to its rear position, and the game begins again.
  • the combed cotton wool runs from the tear-off cylinder pair 5 through the second tear-off cylinder pair 6, a belt funnel 17 and the pull-off roller pair 7 and then as a comb belt to an outlet table 18.
  • the feed cylinder 14 is rotated by a predetermined, adjustable angle during the movement of the lower forceps 10 from its rear to the front position and / or during the movement from the front to the rear position, to the cotton with respect to the lower forceps 10 by a desired amount of food to advance.
  • the feed cylinder 14 is rotated by an electric motor 19.
  • the motor 19 is expediently a highly dynamic DC or three-phase motor, e.g. a stepper motor or a servo motor.

  • the control device 20 is acted upon, for example, by the output signal of a position transmitter 21, which scans markings, for example teeth, on an element (not shown) carried on the round comb shaft 4, for example magnetically or optically.
  • the round comb shaft 4 makes one revolution each time the pliers unit 10, 12 moves back and forth.
  • the control device 20 is designed in such a way that the phases of the drive pulses emitted by it can be adjusted with respect to the movements of the forceps unit 10, 12, so that the motor 19 feed roller 14 in each case at an adjustable time during the forward movement of the forceps unit and / or in one adjustable time during the return movement of the pliers unit rotates.
  • the amount of food can also be set, i.e. the angle through which the motor 19 rotates the feed roller 14 during each forward movement and / or during each return movement of the forceps unit 10, 12.
  • the lengths and / or the amplitudes of the output drive pulses can be set in the control device 20, or, if the motor 19 is a stepper motor, the number of pulses which the control device 20 can set during each forward movement and / or during each can be set Returns movement of the pliers unit 10, 12 releases.
  • a speed-controllable electric motor 22 preferably a geared motor, is provided for driving the winding roller 2 (and possibly also the winding roller 1 via a coupling, not shown), and the control device 20 is designed such that it drives the motor 22 with an electrical current of this type tension and / or feeds such a frequency that the peripheral speed of the winding rollers 1 and 2 is always in a substantially constant ratio to the average peripheral speed of the intermittently rotating feed cylinder 14.
