Definitions

  • the present invention relates to a device for separating a fiber template from mutually slidable staple fibers with two driven roller pairs, which form two clamping lines for the fiber template guided between them.
  • a fiber template of mutually slidable staple fibers in the sense of this invention is understood to mean any fiber aggregate that extends in the longitudinal direction, regardless of the shape of its cross section, i. H.
  • Both fiber aggregates with a round or centrally symmetrical cross-section such as the conveyor belts of the staple fiber spinning mill) as well as with the elongated cross-section (such as the fiber floss in a lap-forming cotton machine or the fleece of a card of the staple fiber spinning mill), in which the fibers in one any shape (e.g. as longitudinal single fibers or flakes), and which essentially only stick together through the adhesive forces of the fibers to each other.
  • GB-A 967 366 also describes separation methods or devices for separating a fiber template, in which a clutch is required to interrupt the drive to the rear pair of rollers as seen in the direction of travel and thus does not separate the fiber template by actuating the clutch interrupted drive of the front pair of rollers.
  • Fig. 6 of GB-A 967 366 also shows another solution in which the fiber template can be separated by a separate drive for the front pair of rollers, this solution, just like the other solutions described in GB-A 967 366, requires one Large number of gears, which leads to high manufacturing costs.
  • the object of the present invention is therefore to propose a device of the type mentioned at the outset which is simple and reliable in construction, requires little maintenance work and in particular does not require a clutch in the drive system of both pairs of rollers.
  • a device of the type mentioned which is characterized in that the two pairs of rollers are kinematically coupled by means of a flexible force transmission element, and that the element around the drive roller of the driven roller of each pair of rollers and at least two further stationary deflection rollers, and around two connected to a roller tandem, movable rollers is guided so that it forms a loop leading over one of the rollers of the tandem loop between the drive rollers, and between the two deflection rollers forms a loop leading over the other role of the tandem, so that by moving the portable Roll tandems make one of the loops shorter by a certain amount, while the other becomes longer by the same amount, so that one pair of rollers can be rotated relative to the other and the fiber template clamped between the clamping lines is separated by pulling apart.
  • the figure shows the device according to the invention in a schematic, greatly simplified representation, and that is applied, according to a preferred embodiment of the invention, in a winding-forming cotton machine of the combing preparation process.
  • a plurality of staple fiber tapes are pulled out of the supply cans 1 and 2 (which are only shown schematically and on a much reduced scale in the figure) and doubled, that is, by suitable means, not shown united by side by side to a wide fiber template 3.
  • a fiber template 3 normally has a width of approximately 30 cm.
  • This fiber template 3, which forms a thick cotton wool, is wound onto a roll 4. This happens that the fiber template 3 is attached to the surface of the sleeve 5 in any way at the beginning of the winding process.
  • the sleeve 5 is supported on a friction roller 6, which is driven by means mentioned later, and is set in rotation by this by frictional engagement.
  • the fiber template 3 winds up around the sleeve 5 and forms a winder 4 that becomes ever larger in diameter.
  • the sleeve 5 must of course shift relative to the friction roller 6 in accordance with the widening diameter, which is ensured by appropriate holding means.
  • such holding means have the form of two guides 7, 8 which are perpendicular to the friction roller 6 and which guide the sleeve 5 on both edges (only one edge shown).
  • other types of holding means for the sleeve 5 can be provided, such as. B. closing arms, which guide the sleeve 5 along a circular path, etc.
  • the sleeve 5 is pressed onto it by suitable means (not shown) in order to increase the entrainment by the friction roller 6. It can further be provided that the drive of the winding 4 does not take place by means of cleaning by the friction roller 6, but that the sleeve 5 itself is driven by means of drive elements (not shown), with suitable control means then ensuring that the speed of the winding 4 corresponds to that increasing diameter of the same is continuously adjusted.
  • suitable drive types i. H. those in which the winding 4 is set in rotation by direct drive of the sleeve 5 and combined by a friction roller can be used in the context of this invention.
  • rollers 9/10 and 11/12 are provided according to the invention, which form two clamping lines m and n for the fiber template 3 guided between them.
  • the lower rollers 9 and 11 of the roller pairs are driven rollers, as will be explained in more detail, and are rotatably supported about the axes 13 and 14 in a frame of the machine, also not shown, with stationary bearings, not shown.
  • the upper rollers 10 and 12 of the roller pairs are designed as pressure rollers, which are guided vertically movably in a stationary body 17 provided with vertical guides for the corresponding axes 15 and 16 and are pressed against the driven rollers 9 and 11 by means of compression spring 18 .
  • the two driven rollers 9 and 11 of the roller pairs 9/10 and 11/12 are now kinematically coupled according to the invention by means of a flexible force transmission element 19, the element 19 preferably being a slip-free working element.
  • the force transmission element 19 is a chain or a toothed belt which is in engagement with corresponding chain wheels or toothed belt pulleys for the purpose of non-slip transmission of force and movement.
  • the force transmission element 19 is guided around the drive roller 20 or 21 of the driven roller 9 or 11 of each pair of rollers and at least two further stationary deflection rollers 22 and 23, the corresponding axes 24 and 25 of which are rotatably mounted in the frame of the machine, not shown. Furthermore, two movable rollers 27 and 28 connected to a roller tandem 26 are present in the track of the force transmission element 19. For this purpose, the axes 29 and 30 of the rollers 27 and 28 are rotatably mounted in a common bearing body 31.
  • the force transmission element 19 forms a loop 32 and 33 between the drive rollers 20 and 21 and the roller 27 and between the two deflection rollers 22, 23 and the roller 28 the rollers 20, 21, 22 and 23 are fixed in place, the scope of the flexible force transmission element 19 is independent of the position of the roller tandem 26.
  • a piston / cylinder 34, 35 system is provided in FIG. 1, the piston rod 36 of which is connected directly to the bearing body 31.
  • the cylinder 35 is connected by means of a line 37 with a valve 38 to a pressure source (not shown) for a suitable fluid and contains a return spring 39.
  • a pressure source not shown
  • the valve 38 When the valve 38 is opened, the pressure medium flows into the cylinder 35 from below and pushes the piston 34 together with piston rod 36, overcoming the force exerted by the return spring 39, from bottom to top, with which the bearing body 31 z. B. is shifted from position A to position B.
  • the piston 34 together with the bearing body 31 can then be returned to its initial position under the influence of the force of the return spring 39.
  • other methods e.g. purely mechanical drives with toothed rack and pinion, not shown
  • the axis 24 of the deflection roller 22 is equipped with a pulley 40 for a belt 41.
  • the belt 41 is driven by a motor 42 with a pulley 43 and thus sets the power transmission element ment 19 in circulation.
  • the friction roller 6, starting from the axis 14 of the roller 11, is driven by means of the pulley 44, belt 45 and pulley 46, so that there is a kinematic coupling between the roller 11 and the friction roller 6.
  • the belt 45 is preferably selected as a toothed belt.
  • a chain drive can of course also be used for the friction roller 6.
  • the ratio of the diameters of the pulleys 44 and 46 is chosen essentially equal to the ratio between the diameters of the roller 11 and the friction roller 6, so that between the clamping line n and the friction roller 6 the fiber template 3 does not warp (if one is from a possible here negligible tension delay) is subjected.
  • the type of drive of the power transmission element 19 and the friction roller 6 shown here is not the only one that can come into question in the context of this invention.
  • rollers 9 and 11 (as shown in the figure) have the same diameter and / or are kinematically coupled by means of drive rollers 20 and 21 of the same size. If this is the case, then both driven rollers 9 and 11 of the roller pairs 9/10 and 11/12 have the same surface speed, with which the fiber template 3 during the rotation of the force transmission element 19 around the stationary tandem 26 between the clamping lines m and n without Delays are transported further.
  • one of the roller pairs is kept in relation to the other during the displacement of the roller tandem 26, so that the relative rotation of the second roller pair must take place in relation to a stationary roller pair.
  • This is e.g. B. realized in the device of the figure shown that the roller 9 is braked directly by means of a brake 50 operated by a system cylinder 47 / piston 48 and piston rod 49. The piston 48 is actuated by means of the line 51 and the valve 52.
  • B. the use of a so-called stop motor, d. H. a motor equipped with a brake, also a very good solution instead of motor 42.
  • the motor 42 drives the roller pairs 9/10 and 11/12 via the belt 41 and the force transmission element 19, which continuously pull the fiber template 3 out of the cans 1 and 2 and convey them to the winding 4.
  • the winding 4 rotates by friction on the friction roller 6, which is also driven by the motor 42, and the fiber template 3 is wound onto the winding surface.
  • the motor 42 is switched off.
  • the fiber template 3 between the clamping lines m and n and from the clamping line n to the roll 4 is maintained throughout.
  • valves 52 and 38 are actuated simultaneously or in quick succession, with which the brake 50 comes into action and the roller tandem 26 is shifted from its lower position A to the upper position B shown in broken lines.
  • the drive roller 21 and the deflecting roller 23 must rotate clockwise, which causes the rollers 11, 12 to rotate in the sense of conveying the fiber template 3 from left to right . Since the rollers 9, 10 stand still, the fiber template 3 is separated between the clamping lines m and n by pulling apart, which is the purpose of the invention.
  • the diameter d of the drive roller 21 of the driven roller 11 of the further rotated roller pair 11/12, the diameter D of the driven roller 11 and the maximum stack length s of the fiber template 3 there is preferably the following relationship
  • the friction roller 6, which is kinematically coupled to the roller 11, is also rotated by the same superficial distance, so that the fiber template 3 is always in order is wound onto the surface of the winding 4.
  • the severed template end (not shown) can now be wound onto the surface of the roll 4 by two methods, thus providing the roll 4 for its replacement.
  • the motor 42 can be put into operation again for a short time; as a result, as during normal operation, the rollers 9, 11 and 6 are driven, with the result that the fiber feed is shifted from left to right before and after the separation point.
  • the motor 42 is switched off again and the winding 4 is exchanged for a new, empty sleeve 5 either manually or automatically, using known means, not shown.
  • the displacement path L of the tandem 26 is chosen so large that not only the fiber template 3 would be separated by the relative rotation of the rollers 11, 12 and 6 compared to the rollers 9, 10, but that the Separation point of the fiber template 3, or the end thereof on the winding side, is conveyed to the surface of the winding 4, while the rollers 9 and 10 are stationary.
  • the winding change operation can be carried out in a known manner.
  • the return of the tandem 26 from the position B to the position of normal operation A can in this second case (in which no fiber template 3 remains between the clamping line n of the roller 11, 12) immediately done during the change operation; it does not matter here whether the rollers 11 and 12 have to turn back (counterclockwise).
  • the first method in which the fiber wadding 3 is already pulled through the clamping line n of the pair of rollers 11/12 before the change operation, the resetting of the roller tandem 26 from position B to position A during normal operation, i. H. during the following construction phase for the next winding 4. This movement is carried out at such a low speed compared to the surface speed of the rollers 9, 11 and 6 that the change in the fiber mass of the fiber template 3 after the rollers 11, 12, which is naturally given, is negligible.
