Definitions

  • the invention relates to a winding machine and a method for winding slivers of cotton wool on a sleeve, according to the preamble of claim 1.
  • Winding machines are known for producing a lap roll in which the lap roll is pressed against the winding rolls with a high force of up to 15,000 N during the winding process.
  • This high force is necessary to densify the batting so far that 300 m winding length can be wound into a lap roll with about 550 mm diameter.
  • the disadvantage is that is pulled by this high force of the resulting lap roll in the gusset between the rigid winding rollers and thereby permanently deformed.
  • the compressive force on the lap roll and the deformation cause the lap roll to warm to 40-60 ° C, causing sticky substances in the cotton to stick to the fiber layers, resulting in increased hairiness when unrolled.
  • a further development of the classic winding process by means of winding rollers represents the tape winding technology, in which instead of the two winding rollers, a winding tape is used.
  • the winding tape encloses the lap roll on its outer circumference depending on the embodiment at an angle of 155 ° to 270 °.
  • the tensile force acting on the winding band acts as a winding force, which is distributed over the circumference of the wrap.
  • the wrapping tape reduces the deformation of the lap roll to a minimum because the wrapping tape absorbs possible deformations. This has the disadvantage that the winding tapes must be replaced due to this load after a few months in operation, which is very expensive.
  • the band Since the length of the band must cover the winding circumference of a full lap roll as well as the opening for removing the lap roll, the band is designed much longer than needed for the pure winding process. Therefore, the leadership of the band and the constant tension hold the winding tape constructively extremely expensive, which can be compensated only partially due to the higher winding speed.
  • the object of the invention is the development of a winding machine for winding slivers of cotton wool, which has a high productivity, can be produced inexpensively and has a low maintenance requirement.
  • the invention includes the technical teaching that the cotton is guided by a first endless circulating belt to the sleeve, and that a second endless circulating belt guides the cotton around the sleeve.
  • the lap roll is formed by a single circumferential belt
  • a delay due to different speed can be adjusted, whereby the hardness of the coil is adjustable.
  • each belt has a separate drive.
  • the distortion may be in the range of a speed difference of the belts of 0.5 to 5%, preferably 2%.
  • each of the two belts wraps around the sleeve or the lap roll during the winding process by 50 ° to 120 °. This ensures a sufficient investment of the belt to the lap roll, with the entrained air is pushed out through the cotton wool.
  • the belts and the associated deflections are preferably arranged symmetrically to the sleeve or to the lap roll.
  • the belt and the associated deflections to the sleeve or to the lap roll can at least one Strap around the lap roll during the wrapping process by 50 ° to 180 °.
  • each belt is guided around at least two deflections, wherein the winding is formed in the region between the deflections.
  • At least one deflection is designed to be movable such that a sleeve can be fed between the belts, or the lap roll from the winding machine can be discharged.
  • both deflections are designed to be movable apart.
  • each belt has a separate tensioning device, with which the tension of each belt is individually adjustable.
  • a lap roll is formed between two endlessly circulating belts. This results in a structurally simpler guidance and the structure of the belt tension due to the absolutely lower elongation is easier and more accurate to implement than in the prior art.
  • each of the two belts wraps around the sleeve or the lap roll during the winding process by 50 ° to 120 °, whereby a sufficient contact surface is formed, with the entrained air to push out of the cotton wool.
  • at least one belt wraps around the sleeve or the lap roll during the winding process by 50 ° to 180 °.
  • the cotton wool 2 runs in the material flow direction (arrow) to the pressure rollers 3a-3d.
  • the cotton wool 2 orbits at least partially in succession the pressure rollers 3a, 3b, 3c and 3d between which it is stretched until it is caught between the pressure roller 3d and the deflection 8 by the first belt 6 and fed to the sleeve 4 and wound up.
  • the sleeve 4 can be clamped at its end faces by means of plates and / or guided, whereby at the same time the cotton wool 3 undergoes a lateral guidance for the winding process.
  • the cotton wool 2 is guided by the first belt 6 by about 50 ° to 120 ° to the sleeve 4 and passed through the adhesion to the sleeve 4 in the gusset between the deflections 10, 11 to the second belt 7. Also, this second belt 7 leads the cotton to about 50 ° to 120 ° to the sleeve 4 until a new layer of cotton wool covering the first layer.
  • the sleeve 4 rotates counterclockwise with the lap roll 5.
  • the belts 6, 7 are each guided by an upper deflection 8, 9 and a lower deflection 10, 11.
  • the belts 6, 7 are each guided and deflected by a tensioning device 12, 13 with which the belt tension for the winding operation and for the following functions (sleeve feed and winding ejection) is generated.
  • This embodiment requires an approximately symmetrical arrangement of the belts 6, 7 and their deflection 8, 9, 10, 11 ahead. In an asymmetrical arrangement, a looping of a lap roll by a belt (6 or 7) by about 50 ° to 180 ° is possible.
  • the drive of the belt 6, 7 can take place via a driven deflection 10, 11 or 8, 9, wherein for reasons of constructive arrangement, the deflection 10, 11 is more suitable.
  • the drive of the belt 6, 7 also take place through the rollers of the tensioning device 12, 13, which at the same time take over a plurality of functions.
  • Anwickeln can be provided in the gusset between or below the deflections 10, 11 one or more nozzles that briefly press the beginning of the cotton wool 2 to the sleeve 4 with air until the beginning of the cotton wool 2 taken from the belt 7 becomes.
  • the lap roll 5 may at least partially rest on the deflections 10, 11, which may depend inter alia on the distances between the deflections 8 and 10 or 9 and 11.
  • a resting on the deflections 10, 11 may have the advantage that the voltage and thus the load on the belt 6, 7 can be reduced, which extends their life. This presupposes that with a lateral guidance of the lap roll by the side plates these can move flexibly in the height.
  • the device according to the invention has the advantage, in contrast to the prior art, that the belt guide can be realized more simply because of the shorter belts and the associated absolute belt elongation, since the compensation of the belt tension can be realized over a shorter travel path.
  • Another significant advantage over the single-belt solution according to the prior art is the setting of a delay between the two belts 6 and 7, over which the hardness of the lap roll 4 is adjustable. It has been found that the open gap or gusset between the deflections 10 and 11 has no effect on the winding quality or a possible entrainment of air.
  • FIG. 2 It is shown how the upper deflections 8, 9 were moved outwards to make room for the supply of a new sleeve 4.
  • the lap roll 5 with the sleeve 4 off FIG. 1 is shown in phantom for comparison.
  • the new sleeve 4 can be vertically inserted from above into the gap between the belts 6, 7, or fed horizontally.
  • the sleeve 4 is chambered and guided laterally on their end faces of winding plates, not shown.
  • the deflections 8 and 9 are again in their original position FIG. 1 method.
  • the mobility of the rollers of the clamping device 12, 13 is not shown for reasons of simplicity.
  • the cotton wool 3 is taken away from the belt 6 after the last pressure roller 3d and fed to the sleeve 4. Due to the smaller diameter of the sleeve 4 compared to the finished lap roll 5, the cotton wool 2 is guided only about a circumference of about 70 ° to the sleeve 4, wherein the circumference increases with increasing diameter of the lap roll 4 to about 120 °.
  • the sleeve 4 moves vertically with the lateral sleeve plates.
  • the movable arrangement of the deflection 8, 9 can be done by means of horizontally arranged guides. It can also be down at an angle take place, this movement can also be done on a straight guide or by means of swivel joint.
  • the finished lap roll 5 is deposited from the winding machine 1 on a transport device 14.
  • the transport device 14 may be formed as a carriage or as a conveyor belt. Before that, however, the cotton is torn off between the pressure rollers 3c and 3d, or 3b and 3c, or between the pressure rollers 3a and 3b, stopping a pressure roller 3a or 3b or 3c while the forward direction of the pressure roller 3b, 3c or 3d continues.
  • At least one of the deflections 10 and 11 must move apart to make room for the passage of the lap roll 5. This divergence could be sufficient depending on the constructive implementation, to transfer the lap 5 down to a transport device 14. It may be useful to drive the pulleys 8 and 9 apart so that when you shut down the lap roll 5 this is not damaged by the belt 6, 7 on its outside. In this embodiment, both deflections 10, 11 proceed to the outside and create space for the removal of the lap 5. In an asymmetrical arrangement of the belt and the deflections, it may be sufficient if only one of the deflections (10 or 11) is moved outward.
  • the belts 6, 7 are covered with sufficient tension, and the rollers of the clamping devices 12, 13 can be moved apart so that the belts 6, 7 are guided in the lateral guides and the belt 6, 7 have a minimum voltage.
  • the deflections 10, 11 After the cotton roll 5 is output from the winding machine 1, first the deflections 10, 11 return to their original Position, according to FIG. 2 to pick up and hold the empty sleeve. After then again the deflections 8, 9 were moved to its original position, the tension of the belt 6, 7 are rebuilt on the tensioning devices 12, 13 and set the belt to form a new roll in motion.
  • the sleeve 4 is located on the deflections 10, 11, which may be a relief of the belt 6, 7 for the winding process. Depending on the belt tension, however, the sleeve 4 can also be adjusted centrally between the deflections 8 and 10 or 9 and 11 and can not rest on the deflections. For this purpose, preferably the side plates are positioned stationary.
  • the winding machine according to the invention has the advantage that by the use of two belts 6, 7 a delay can be established by the belts 6, 7 are operated at a different speed.
  • the winding quality can be influenced by the cotton roll is wound harder or softer depending on the fibers used.
  • By using two separate belts 6, 7 results in a structurally simpler guidance and the construction of the belt tension due to the absolutely lower elongation is easier and more accurate to implement.
  • Another significant advantage is that an empty sleeve 4 supplied from one side between the belt 6, 7 (here in the embodiment above) and the finished lap 5 of the other side between the belt 6, 7 (here in the embodiment from below) are removed can. The idle time for the change can thus be significantly reduced.
  • the invention further provides a control for the belt tension, which can preferably be done depending on the wound and measured length of lap or lap length, wherein the cotton quality, the elastic behavior of the lap roll 5, for example due to the moisture of the cotton wool, in the control With can be taken into account.
  • the current diameter of the lap roll 5 is interpolated over the winding length and the aforementioned parameters, so that via the controller, the tensioning device 12, 13, the belt 6, 7 so far releases or clamps that the lap roll 5 with the largest possible wrap angle through both Belt 6, 7 is wound.
  • a lateral belt guide can be integrated into the deflections 8-11.
  • a lateral belt guide can also be arranged between the deflections 8 - 11 within the winding machine.
  • the belts 6, 7 may preferably be formed as a flat belt.
  • the flat belts can have many small holes with a diameter of 0.5 mm to 5 mm in order to dissipate the air entrained in the cotton wool 2, that is to say have a perforation.
  • the belts 6, 7 may be constructed in multiple layers, wherein an inner layer is formed so that it has a high strength and low elongation.
  • an outer layer which comes in contact with the wadding 2 should preferably have an acceptable friction without the wadding being liable to stick to this layer.
  • the belt 17 may have on its rear side at least one wedge shape, preferably a plurality of wedge shapes, which engage in corresponding grooves of the deflections 8 - 11 and the tensioning device 12, 13. With the arranged on the back of the belt wedges integration of the belt guide in the rotating rollers 8 - 13 is ensured.
  • each belt 6, 7 may be formed as adjacent belt strips.
  • each belt strip can vary in tension in a predetermined range, whereby the winding quality over the winding width is adaptable.
  • 5 broad belt strips are preferably used to the edge of the lap roll, which can be narrower to the center of the lap 5.
  • These belt strips can also have at least one wedge on their rear side, which engage in a corresponding groove of the deflections 8 - 11 or the tensioning device 12 - 13. This also ensures a lateral belt guide.
  • the arrangement of the winding machine 1 after the FIGS. 1 to 3 shows a vertical arrangement in which the sleeve is supplied from above or laterally and the finished lap roll is transferred to the bottom of a transport device 14.
  • the course of the belt 6, 7 also takes place in a vertical orientation.
