Definitions

  • the present invention relates to a device for laying a thread on a cross-wound bobbin at a plurality of winding units operated next to one another, a thread guide being provided for each winding unit, with a traversing element connecting the thread guides, which can be moved together with the thread guides by a traversing drive along the winding stations.
  • the spun yarn runs through a thread guide which moves back and forth in the bobbin depending on the delivery speed and the crossing angle of the thread.
  • the superposition of the rotary movement of the bobbin with the translational movement of the thread guide creates a cross-wound coil, the so-called cross-wound bobbin. Due to the large number of spinning stations working side by side, it is advantageous to move the thread guides of all spinning stations on one spinning machine side synchronously.
  • the large number of spinning positions also means that the spinning machine is very long.
  • the length of the machine can be over 30 m and it contains over 200 spinning positions.
  • a rod For synchronous running of the thread guides, a rod, called a traversing rod, is usually set into an oscillating, translatory movement via a cam mechanism or a control roller.
  • the traversing rod is essentially as long as the spinning machine and there is a thread guide on it in front of each spinning station.
  • the object of the present invention is therefore to reduce the mechanical loads on the traversing elements and the drive unit and thus to reduce the wear on the parts and to significantly increase the traversing speed.
  • Another task is to design a drive element in such a way that an optimal coil structure is made possible.
  • the traversing element is expediently designed as a flexible component which is rigid in the traversing direction for transmitting tensile forces.
  • This configuration of the traversing element means that many light components such as wires, cords, ropes, belts, tapes, chains can be used.
  • the simplest and least expensive embodiment for the traversing element is a steel wire. It combines all the required characteristics in an advantageous manner. But it is also e.g. a strap or steel band can be used.
  • Driver devices are attached to the traversing element to accommodate the thread guides. These can be made of different materials, e.g. Plastic or steel exist and be attached to it with a variety of joining methods (pressed, glued, etc.). The distances between the driver devices correspond to the distances between the spinning positions.
  • the driver devices can be dispensed with.
  • the thread guide is attached directly to the steel wire and can be moved as required for adjustment.
  • this inexpensive solution requires greater care in assembly to prevent misalignment during operation.
  • the thread guides are detachably connected to the steel wire. They can therefore be replaced individually or readjusted. It is also advantageous if the individual thread guides can be dismantled independently of the other thread guides and removed from the traversing element. This ensures that a quick and inexpensive repair is possible in the event of a defect in a thread guide.
  • the traversing element is connected to the thread guide essentially at the center of gravity of the thread guide is. Forces that can occur here arise, among other things, from friction, air resistance and the resistance of the thread to be guided. Since these forces are essentially constant over a wide range of motion, a point can be found where the sum of these forces and the resulting torques is the lowest. If the thread guide is fastened at this point, the thread guide will tilt the least during acceleration and thus generate the least counterforce.
  • the thread guides can advantageously be adjusted relative to the bobbins by means of at least one adjustable roller.
  • the traversing element with the thread guides attached to it is rotated further via the adjustable roller without being in engagement with the drive and thus varying its longitudinal positioning.
  • an adjustment can also be carried out which corrects the misalignment between the traversing element and the thread guide. This takes place via a translational offset of the roll transversely to the direction of movement of the thread guides. The adjustment is made easier if there are adjustment marks on the spinning machine and / or on the traversing belt which indicate the correct position of the thread guides.
  • the thread guides can also be advantageous for the thread guides to be adjusted relative to the bobbins by means of at least one adjustable drive platform.
  • the adjustment is carried out in such a way that the drive platform is displaced in translation.
  • the thread guide slides on the guideway.
  • At least one stationary guideway is preferably provided for the movement of the thread guide.
  • the guideway should enable the thread guide to have a translatory movement that is resistant to twisting.
  • the friction between the thread guide and the guideway should be low so that the tensile resistance remains low during acceleration.
  • it must therefore be ensured that the friction partners are cheap.
  • the fact that the thread guide has a low mass inertia also contributes to the smooth running of the thread guide. This reduces the acceleration and braking forces.
  • the traversing element runs along a plurality of winding points arranged next to one another and is deflected at the end of the machine and returned to the drive element.
  • Another proposal provides for operating both machine sides with one traversing element.
  • the drive in the reversing area of the traversing element is particularly advantageously arranged, since the direction can be reversed with the drive, for example with a roller.
  • the idling part of the traversing element can be avoided.
  • one of the drive elements is an energy store.
  • This energy storage reproduces the stored force depending on the path and has an extremely high efficiency.
  • a spring can be used which, in addition to introducing the tensile force in one direction, also tension the traversing element and permits simple adjustment of the thread guides. Depending on the direction of movement, the forces required for the reversal are generated either by the drive element or the spring.
  • At least one damper element can act on the traction means between the drive element and the traversing unit in order to dampen the acceleration peaks occurring due to the change in speed.
  • a servo motor which is controlled by a microcomputer, ensures that the stroke, speed and acceleration of the traversing unit are determined solely by the rotational movement of the servo motor. They can be set independently and very precisely in the simplest way, and varied during the formation of the coil. In addition, only a minimum of wear-prone components are required for the drive. Due to the low mass of the moving parts of such a motor, the mass to be accelerated during the traversing can be reduced at the same time, which enables a higher thread delivery.
  • the direction of movement can be reversed particularly quickly.
  • the traversing element traction means, or pressure and traction means when using a traversing rod
  • the traversing element is held securely so that buckling is prevented.
  • deceleration or acceleration can be faster.
  • the use of a microcomputer for controlling cooperating servomotors is particularly favorable.
  • the desired traversal properties can be entered as programs using the microcomputer.
  • the effort of mechanical traversing devices to avoid bad coils (image windings, edge beads etc.) can easily be replaced by a control program.
  • An optimal coil structure is achieved in that the traversing unit is driven by at least one servo motor, which is controlled by a microcomputer.
  • the traversing unit In order to convert the rotary movement generated by the servo motor into a straight back and forth movement of the traversing unit running at high speed, the traversing unit is driven via a gearwheel which engages in a rack assigned to the traversing unit.
  • the gearwheel can be fastened on the motor shaft or also on the output side of a gear downstream of the servo motor to reduce the motor speed.
  • the servo motor is expediently a brushless three-phase motor, which is particularly favorable for high performance, e.g. over 3 KW, can be used, is responsive and has a high torque from standstill to high speeds.
  • FIG. 1 shows a traversing unit 1 in front of a package 30.
  • Traversing unit 1 is understood to mean the structural unit of thread guide 10, traction means 11, 12.
  • a guide track 13, which guides the thread guide 10, extends along the winding stations to absorb web guide forces.
  • the thread guide 10 is shown in a longitudinal section.
  • the positive connection of the thread guide 10 via the driver device 110 on the steel wire 11 can be clearly seen.
  • the driver device 110 which in this case is shaped as a spherical structure, engages in the center of gravity 100 of the thread guide 10.
  • the distance 1 M of the successive driver devices 110 corresponds to the spinning position distance 1 S or the distance between the ends of two successive cross-wound bobbins 30.
  • the thread guide 10 is divided into the components 101, 102 and 103.
  • the guideway 13 is fixed in the end frames 2.
  • a fastening of the guideway 13 is, however, also possible at all of the points which are not traversed by the thread guides 10, ie the guideway 13 can also be fastened at each spinning station 4.
  • the main drive directions 130 and 131 are determined by the position of the guideway 13 on which the thread guides 10 slide or roll in a rotationally fixed manner.
  • the superimposition of the oscillating, translatory movement of the thread guide 10 with the rotational movement of the package 30 results in a crosswise winding of the spun yarn 31 on the package 30.
  • the exemplary embodiment shows a two-part thread guide 101 and 103. However, it is also a one-part thread guide 10 mountable and adjustable by adjusting the guideways 13 to each other.
  • the steel wire 11 is fixed in the center of gravity 100 by a clamping screw 104. This type of attachment enables the individual thread guides 10 to be adjusted relative to one another, ie a change in the distance 1 M.
  • the steel wire 11 is clamped in the center of gravity 100 by the connection of the thread guide parts 101 and 102. Continuous adjustment of the distance 1 M is also possible here.
  • the thread guide 10 is not slidably mounted on the guideway 13, but rather in a rolling manner.
  • the roller bearings 105 allow the thread feeder 10 to move with extremely little effort.
  • Fig. 4 shows another type of traction means. Instead of the steel wire 11, a traction band 12 was used.
  • Various materials such as e.g. Steel, plastic or composite materials such as Belts in question.
  • the installation does not have to take place in the position shown, but can be done in any position around the center of gravity 100, i.e. e.g. upright, depending on how the deflection of the traction means 11, 12 in the end frames 2 is cheaper.
  • a drive element 50 drives the steel wire 11 in both main directions 130 and 131.
  • the drive element can be either a motor with a direct effect on the traversing element or a motor-driven traversing gear.
  • a special design of a traversing drive is described further below (FIGS. 11, 12).
  • the steel wire 11 with the thread guides 10 attached to it is deflected via the deflecting rollers 20 and returned to the drive element 50.
  • the deflection rollers 20 can be adjustable in position so that the position of the thread guides 10 or of the steel wire 11 relative to the cross-wound bobbins 30 can be adjusted.
  • a Another possibility of adjustment is to vary the zero position of the drive element 50 and its position. It is advantageous in this embodiment that only one drive element 50 is required for the large number of winding units 3.
  • a disadvantage is the large mass of steel wire 11 and thread guide 10 to be moved, which has to be accelerated by a drive element 50 and braked again.
  • the drive element 50 is responsible for both main directions 130 and 131 of a number of winding units 3.
  • the parallel row of winding units 3 is operated by a further traversing unit 1.
  • FIG. 7 A principle similar to FIG. 6 is shown in FIG. 7.
  • the drive element 51 is responsible for the main drive direction 130 and the drive element 52 for the main drive direction 131.
  • the moving masses could be reduced again, although two motors 51, 52 are used per row of winding units.
  • the traversing unit 1 can be adjusted and tensioned by translationally displacing at least one drive platform 5. For a simple adjustment, it can be advantageous if 3 markings are attached to the winding stations, with which the thread guides 10 are to coincide.
  • the acceleration peaks which arise when the direction of the thread guides 10 is reversed can be reduced by spring-damper systems 6.
  • the spring-damper systems 6 should be installed between the drive element 50, 51, 52, 53 and the tension band 12 or the steel wire 11 in order to show the best effect.
  • Spring-damper systems 6 have certain characteristic curves which, in cooperation with the acceleration characteristic curves of the drive elements 50, 51, 52, 53, can advantageously influence the acceleration and deceleration of the thread guides 10. This interaction of the components to form a specific characteristic curve causes the winding of the package 30 with yarn 31, which is typical for the characteristic curve, since at a higher traversing speed, there is also a larger crossing angle of the yarn layers on the package 30.
  • FIG. 9 shows the relieved spring-damper system 6 while the steel wire 11 is moving in the main drive direction 130.
  • the stationary housing 60 there are an energy store 62 and a damper element 61 through which the steel wire 11 is passed. If the traversing unit 1 reaches the vicinity of a dead center, a driver device 110 fastened to the steel wire 11 enters the spring-damper housing 60 and compresses the compression spring 62 with the aid of the damper element 61. When the dead center is reached, the compression spring 62 is tensioned and accelerated the traversing unit 1 after the release for a movement in the main drive direction 131. After the spring 62 has been released, the drive element 50, 51, 52, 53 takes over the further movement of the traction means.
  • the spring-damper system 6 In addition to rapid acceleration of the traversing unit 1, the spring-damper system 6 also causes the thread guides 10 to be reversed smoothly and thus considerably relieves the mechanical strain on the drive elements 50, 51, 52, 53. By providing separate components for the transmission of the acceleration elements and the web guiding forces the thread guide 10 has succeeded in significantly increasing the traversing speed while at the same time reducing the mechanical loads.
  • FIG. 11 shows a traversing unit 1 with a drawstring 12 which is driven by a servomotor 501.
  • a conventional traversing unit with a traversing rod can be driven just as well and advantageously with this type of drive.
  • the drawstring 12 extends over a plurality of winding positions and is guided in a plurality of slide bearings 121 and is held and tensioned by deflection rollers 21, similar to FIG. 6.
  • the drawstring 12 is moved back and forth to form a cheese. This movement is indicated by the double arrow P.
  • the thread laying at each winding point is carried out by thread guides 10 which are fastened on the drawstring 12 and thus follow its traversing movement.
  • the cross-wound bobbins 30 are driven by a rotating drive roller 33 on their circumference and independently of the drive of the drawstring 12.
  • the guideway 13 for the thread guide 10 can be dispensed with. The guidance is achieved by the tightened tension band 12 together with its bearing in a slide bearing 121, which practically represents a shortened guideway 13.
  • the drawstring 12 is driven by a servo motor 501, the rotational movement of which is converted into a straight back and forth movement of the drawstring 12 by a gear 55 in conjunction with a toothed rack 56.
  • the toothed rack 56 in which the toothed wheel 55 engages, is mechanically coupled to the drawstring 12 or is also integrated therein and is, for example, guided and mounted in a sliding manner.
  • a gear 57 is arranged downstream of the servomotor 501 to reduce its speed and the gear 55 is arranged on the output side of the gear 57. The gear 57 permits an increase in the torque and thus an increase in the radius of the gear 55.
  • the gear 55 can, if appropriate, also be fastened directly on the motor shaft of the servo motor 501. It is also possible to use other suitable mechanical devices for converting the rotary movement of the servo motor 501 into a straight back and forth movement of the traversing unit 1, for example a spindle and a spindle nut for a slow traversing.
  • the servo motor 501 used is preferably a motor with a particularly small rotating mass, which is also powerful and responsive and has a large torque from standstill to high speeds in both directions of rotation for acceleration and deceleration Has.
  • a brushless three-phase servo motor, for example, meets these requirements. This is particularly advantageous for use as a drive for the traversing unit 1 of a machine section or a complete machine, because it can be used to provide the high performance required.
  • the servo motor 501 is controlled electronically.
  • the control device consists of a control part MS with a microcomputer MIC, into which the setpoint values S of rotation angle, rotation speed, rotation acceleration and rotation deceleration or rotation force of the servo motor are entered.
  • the crossing angle of the wound thread layers of the bobbin can be increased, for example, by entering a higher rotational speed and reduced by a lower rotational speed.
  • the thread guide is thereby moved faster or slower along the bobbin, so that the thread is wound onto the bobbin with a greater or lesser inclined position.
  • the stroke of the thread guide is influenced by the angle of rotation, ie, by entering a certain angle of rotation, the thread guide covers a certain stroke according to the desired width of the bobbin.
  • These can be sets of fixed values that are entered digitally via a keyboard, whereby the sequence and the number of repetitions of the sets are also entered.
  • the setpoints can also change over time.
  • a program can be entered, according to which the stroke of the thread guide (angle of rotation of the servo motor) changes constantly, so that an edge shift occurs. A superposition of turns (image winding) is avoided by constantly changing the speed of rotation of the servo motor 501.
  • the control part MS with the microcomputer MIC is connected to a controller R, which in turn is connected to the servo motor 501 via an electrical line 50 and ensures that the actual values of the movement of the servo motor 501 match the target values at all times.
  • the actual values are determined by an encoder or resolver E assigned to the servo motor 501, which is connected via electrical lines 531 and 532 to the controller R and the control part MS with microcomputer MIC.
  • the controller R and servo motor 501 are operated via a line part L connected to the power supply.
  • the drive according to the invention makes it possible to accelerate the drawstring 12 with the thread guides 10 constantly and smoothly at the start of the stroke and to decelerate them at the end of the stroke, and to give them a constant or arbitrarily accelerated and decelerated movement between the acceleration and deceleration phases at the ends of the stroke.
  • FIG. 11 shows an arrangement in which a servo motor controls both directions of movement of the oscillation.
  • one or more servomotors can also be provided for each direction of movement. These are coordinated so that they support each other in their running and acceleration phases and the tension band remains taut. By using two servomotors, the moment of inertia of the rotating parts can be reduced and higher acceleration can be achieved.
  • strokes of the thread guide rod 1 or thread guide 2 are freely programmable with regard to their length during the build-up of the bobbin and their number, image windings and beads on the bobbin ends can be avoided in a simple manner by appropriate choice and sequence of shortened strokes.
  • an arbitrarily selectable stroke shortening can be used, which takes place after a likewise arbitrarily selectable number of maximum strokes of the thread guide rod 1 at the start of winding and then after a predetermined number of equally long strokes.
  • the two stroke end positions are shifted inward by the same amount.
  • periodic shortening and again lengthening can be provided as part of the continuous stroke shortening, the two stroke end positions being shifted inward or outward by the same amount. This also prevents image winding.
