Definitions

  • the invention relates to a combing machine with a pair of pliers, which can be fed with staple fiber material to be combed, a rotatable circular comb roller which carries at least one circular comb segment for combing out a fiber beard held by the pliers, and a tear-off device for tearing off the combed fiber beard from the pliers.
  • the tear-off device contains tear-off cylinders which are arranged adjacent to the circular comb roller and are rotated back and forth during operation with a pilgrim step movement.
  • the pliers are usually moved between a retracted, closed position, in which the clamp line of the pliers lies at the circumference of the circular comb segment, and an advanced, open position, in which the clamp line is closer to the tear-off cylinders, by a larger distance, e.g. about 6 to 7 cm, moved back and forth.
  • the working speed of such combing machines is limited by the inertial forces of the parts moved back and forth.
  • a complicated gearbox is also required to turn the tear-off cylinders back and forth.
  • the object of the invention is to design a combing machine of the type specified at the outset in such a way that the disadvantages described are avoided and higher working speeds can be achieved.
  • the tear-off device following the or each circular comb segment, has a tear-off pliers carried by the circular comb roller with two clamping jaws, at least one of which can be moved approximately in the circumferential direction of the circular comb roller, and that adjacent to the circumference of the Round comb roller has a movable comb-pull transport surface for receiving Beards from the or each opening tongs are arranged.
  • the combing machine according to the invention does not require a tear-off cylinder which can be rotated back and forth.
  • the feeding tongs are moved back and forth at most by a relatively small distance and can therefore work faster without difficulty than in known combing machines.
  • the round comb roller can have a relatively large diameter and carry several round comb segments and several tear-off pliers distributed over its circumference, the number of revolutions of the round comb roller or the number of actuations of each tear-off tong is then equal to the number of reciprocating movements of the feeding tongs divided by the number of round comb segments and tear-off pliers on the round comb roller.
  • the ridge feed surface can be moved continuously at a constant speed.
  • the combing machine according to FIGS. 1 to 3 has a pair of pliers 1 with a pair of sub-pliers 2 a fixed axis 3 is pivotable. At least one link 4 is articulated at the rear end of the collet frame 2, which is in contact with an eccentric 5, which is seated on a continuously rotating tong drive shaft 6 mounted on the frame.
  • the lower jaw frame 2 carries a lower jaw plate 7, the front edge of which cooperates with the lower edge of an upper jaw plate 8.
  • the upper tong plate 8 is supported by upper tong arms 9 which can be pivoted with respect to the lower tong frame 2 and which are moved by at least one link 10.
  • the combing machine also has a round comb roller 11 which is arranged on a continuously rotating round comb shaft 12 which is mounted on the frame.
  • the round comb roller 11 carries a round comb segment 13 covered with round comb needles.
  • tear-off pliers are arranged on the side flanges carried by the round comb roller 11.
  • This has a first clamping jaw 15, which is fastened to the flanges of the circular comb roller 11, and a second clamping jaw 16, which is fastened to levers 17.
  • the levers 17 can be pivoted on the flanges of the circular comb roller 11 about pivot pin 18, so that the second clamping jaw 16 can be moved with respect to the circular comb roller 11 approximately in the circumferential direction of the circular comb roller.
  • a compression spring device 19 acting between the flange of the circular comb roller 11 and the lever 17 holds a cam follower roller 20 arranged on the lever 17 against a stationary cam disc 21, which is indicated by a dash-dotted line.
  • a movable comb-pull transport surface in the form of a rotatable drum 22 Adjacent to the circumference of the circular comb roller 11, a movable comb-pull transport surface in the form of a rotatable drum 22 is arranged.
  • the drum 22 has an air-permeable (perforated) peripheral wall, and a vacuum is maintained inside by means not shown.
  • the pliers 1, to which a staple fiber material in the form of a wadding W to be combed is supplied in the usual manner, are in a lowered, closed position. Between the front edge of the lower pliers plate 7 and the lower edge of the upper pliers plate 8, a fiber beard is clamped by the cotton wool W, which is combed out by the circular comb segment 13.
  • the tear-off pliers 15, 16 are open because the cam follower roller 20 rolls on a section of the cam disk 21 with a relatively large radius.
  • the feeding tongs 1 go into an upper position as shown in FIG. 2 and open.
  • the cam follower roller 20 arrives in a section of the cam disk 21 with a smaller radius, so that the compression spring device 19 closes the tear-off pliers 15, 16.
  • the front end of the combed fiber beard is clamped between the jaws 15 and 16.
  • the circular comb roller 11 continues to rotate, the clamped fiber beard is torn off from the cotton wool W lying in the open feeding tongs 1 and pulled through a stationary fixed comb 23 which combs out the rear end of the fiber beard.
  • the closed tear-off pliers 15, 16 with the held fiber beard approach the circumference of the drum 22.
  • the fiber beard F is placed on the circumference of the drum 22 as shown in FIG. 3, where it is held by the negative pressure maintained in the drum.
  • the tear-off pliers 15, 16 open and release the fiber beard F, since the cam follower roller 20 comes into a section of the cam disk 21 with an increasing radius.
  • the feeding tongs 1 return to their lower, closed position and have a next fiber beard ready for combing out through the round comb segment 13.
  • the successive fiber beards F are deposited in a scale-like overlapping manner to form a roving fleece.
  • the extent of the overlap is determined by the ratio between the rotational speed of the circular comb roller 11 and the preferably constant movement speed of the circumference of the drum 22.
  • the comb web is removed from the circumferential surface of the drum 22 by a stationary support element 24 and then compressed between two compacting rollers 25, 26 .
  • the peripheral wall of the drum 22 is covered on the inside with a stationary cover element 27, so that no negative pressure is effective here on the drum peripheral surface.
  • the circular comb roller 11 could carry two or more circular comb segments distributed over its circumference, each with a subsequent tear-off pliers for tearing off whiskers from the feeding tongs 1 and placing the whiskers on the drum 22. This would reduce the speed of the round comb roller 11 and the number of operations of each tear-off pliers accordingly.
  • a round comb roller 32 arranged on a continuously rotating round comb shaft 31 which is fixed to the frame carries two round comb segments 33 and 34.
  • a tear-off pliers with one each are attached to each of the round comb segments 33 and 34 first jaw 35 and 36 and a second jaw 37 and 38 respectively.
  • the first clamping jaws 35 and 36 are fastened to the flanges of the round comb roller 32.
  • the second clamping jaws 37 and 38 are each attached to levers 39 and 40, which can be pivoted about pivots 41 and 42 on the flanges of the circular comb roller 32 and carry cam followers 43 and 44, respectively.
  • the cam followers 43 and 44 will held against a stationary cam 45 by the force of springs, not shown, acting on the levers 39 and 40, respectively.
  • a movable comb-pull transport surface Adjacent to the circumference of the circular comb roller 32 is a movable comb-pull transport surface, which here is the surface of a running endless belt 46.
  • the band 46 is breathable, e.g. perforated, and on its side opposite the circular comb roller 32 a suction box 47 is arranged, in which a negative pressure is maintained.
  • FIGS. 4 and 5 is essentially the same as that of the combing machine according to FIGS. 1 to 3.
  • the feed tongs 1, of which only the lower tong plate 7 and the upper tong plate 8 are partially shown in FIGS. 4 and 5 are to be combed cotton W is fed.
  • the pliers 1 In Fig. 4, the pliers 1 is in a lowered, closed position.
  • the fiber beard of the cotton wool W clamped between the lower pliers plate 7 and the upper pliers plate 8 is combed out by the circular comb segment 33.
  • the feeding tongs 1 go into the upper, open position, as shown in FIG. 5.
  • the pliers jaw 35 comes into the region of the front edge of the pliers plate 7, the front end of the fiber beard is sucked in front of this pliers jaw 35 by a vacuum acting in the region of the pliers jaw 35, for example through a suction line 48.
  • the cam follower roller 41 comes into a section of smaller radius of the cam plate 45, so that the spring (not shown) acting on the lever 41 closes the tear-off pliers 35, 37.
  • the front end of the combed fiber beard is clamped between the jaws 35, 37.
  • the other tear-off pliers 36, 38 place a previously processed fiber beard on the surface of the running belt 46 and open, since its cam follower roller 42 comes in a section increasing radius of the cam plate 45.
  • the successive fiber whiskers are laid overlapping one another in a scale-like manner to form a comb-tension fleece.
