Definitions

  • the present invention relates to the collection of the thread produced or processed by textile machines for winding onto bobbins.
  • thread collection onto a bobbin is effected on tubes supported by a bobbin-holder arm and resting on a rotating roll, by pulling the thread to be wound onto it.
  • the rotating roll can be activated by a motor, transmitting the rotation movement to the tube onto which the thread is wound, or, in an alternative solution, the roll is idle and is entrained by the bobbin in formation which in turn is driven by a motor.
  • the function of the roll is to ensure the pressure necessary for forming a sufficiently compact bobbin and with a correct shape.
  • the thread is spirally wound onto the rotating bobbin as the collecting unit is equipped with a thread-guide device which distributes the thread onto the outer surface of the bobbin, with an axial back-and-forth movement, according to a pre-determined cross angle.
  • the bobbins can have a conical-truncated or cylindrical shape with substantially flat bases, except in some particular cases in which the bobbins are shaped with a marked flaring in the terminal parts.
  • the most widely-used device for distributing the yarn onto the surface of the bobbin with an axial back-and-forth, i.e. transversing, movement consists in a spiral groove situated on the surface of the rotating roll which allows the yarn to effect an axial excursion of a prefixed length, for a pre-established number of revs of the roll itself and with a prefixed trend of the cross angle of the yarn being wound.
  • the thread winding and yarn distribution organs operate according to a fixed velocity ratio.
  • the thread distribution device on the bobbin must be produced with an autonomous thread-guide device which is independent of the movement of the winding organs.
  • the thread-distribution device on the bobbin must therefore be moved by its own activation organ, with which the frequency of the back-and-forth movement, its run, the length of the spiral wound and the winding cross angle, etc. can be modulated each time.
  • Patent EP 311,827 describes an individual thread-guide system for a thread collection unit which envisages moving the thread-guide with a closed toothed transmission belt moved with a step-by-step motor controlled by a microprocessor in the transversing movement.
  • the control of the step-by-step motor with a microprocessor allows the desired winding to be effected, with respect to the cross angle, run and transversing frequency.
  • Patent EP 1,209,114 describes belt-tensioner devices for this type of individual thread-guide.
  • the thread-guide In the intermediate part of its transversing run, the thread-guide is easily activated at the desired velocity, whether said velocity be constant, as in the case of cylindrical bobbins, or when said velocity is variable, as in the case of conical bobbins.
  • the inertia of the thread-guide complex makes it necessary to operate with a lower average speed, with respect to the intermediate excursion section.
  • the greater density at the ends of the bobbin can be reduced by alternating complete transversing runs with shortened transversing runs, or with fixed transversing runs, but with continuous staggering at the two ends.
  • Patent EP 311,784 envisages accumulating kinetic energy with mechanical activation systems of the thread-guide during the intermediate part of its run and transferring it to the thread-guide in the movement inversion phases.
  • Patent EP 453,622 describes a method and a thread-guide device - again activated with constraint to a flexible ring-closed element and activated with a motor piloted with an alternating movement by a control unit - which controls the position of the thread-guide and applies the step-by-step motor with an overcurrent close to its inversion points, thus increasing the braking and acceleration values.
  • This document also envisages further increasing the power transmitted in the movement inversion phases with an elastic system which is engaged and disengaged during the thread-guide run.
  • Patent application EP 1,498,378 describes an analogous thread-guide with an oscillating finger with an energy accumulator having a repulsing effect obtained by positioning permanent magnets in correspondence with the run-end of the oscillating finger, which repel magnets having the same polarity.
  • EP 1.159.217 A as well as the US 6,311,919 B, describe a thread guide with an oscillating finger of the previous type, again actuated by an electric motor in an alternating clockwise/anticlockwise movement, in which torsion springs, with opposing winding directions, are used as energy accumulators and as electrical connectors.
  • EP 302461 A discloses a traversing device for a plurality of winding posts in which the aligned thread guides are connected to a wire actuated in to-and-fro motion by pulleys driven to one or two motors in alternate movement clockwise/anticlockwise.
  • DE 199 63 232 discloses an individual traversing device in which the thread-guide is driven by an endless belt circulating around driving pulleys actuated by their own step-motors driven by a control unit 11. Such motors cooperate together in a clockwise/anticlockwise alternating movement to pull the belt in the to-and-fro rectilinear motion.
  • An objective of the present invention is to produce an individual distribution device of the yarn on the winding bobbin which overcomes the restrictions and drawbacks of the thread-guide devices available in the state of the art and allows extremely high accelerations of the thread-guide in correspondence with the inversion points and consequently to obtain the highest-quality bobbins.
  • the present invention therefore proposes a thread-guide device for the collection of yarns onto a bobbin, wherein the moving parts are not activated by a single motor which acquires the necessary torque, but by at least two motors having smaller dimensions, arranged to as to assist each other in providing the same torque necessary for the moving parts, with an overall lower inertia.
  • the device is also equipped with elastic means which coadjuvate the motors supplying additional energy in correspondence with the inversion points of the movement.
  • the device according to the invention is defined, in its essential components, in the first claim, whereas its variants and preferred embodiments are specified and defined in the dependent claims.
  • figure 1 illustrates the scheme, in principle, of the present invention for the activation of a high frequency thread-guide in an alternating movement.
  • Figure 2 illustrates a preferred embodiment of the principle scheme of figure 1 , with torque springs, wherein figure 2A shows its front view, whereas figure 2B shows its side view, partially sectional.
  • Figure 3 illustrates actuation in a practical embodiment of the invention, in greater detail.
  • Figures 4A and 4B illustrate a preferred embodiment of the activation device of the thread-guide according to the scheme of figure 3 .
  • Figure 5 shows the trend of the return force exerted by the elastic energy accumulation device on the thread-guide.
  • Figure 2 schematically represents a solution in which the motors and pulleys develop a rotation lower than one rev; it is obviously possible to have rotations greater than a rev, completely similar and completely functioning.
  • the bobbin 10 being wound is supported by a bobbin-holder arm for rotating around its axis due to the effect of the contact created by resting on the activation roll 11.
  • the yarn which is wound onto the bobbin 10 is distributed on the surface of the bobbin by the thread-guide 12 which moves with a back-and-forth movement parallel to the axis of the roll 11 and along a guide-rod 13, and as close as possible to the contact point between the roll 11 and the bobbin 10.
  • the thread-guide device 14 envisages that the transversing movement of the thread-guide 12 be activated with an open flexible element 15 having an extremely low inertia, which can be a wire or cord, as shown in the figures - or an equivalent known element, for example smooth or toothed belts and so forth, - to which said thread-guide 12 is fixed with a plug 42 which slides along the rod 13.
  • an open flexible element 15 having an extremely low inertia, which can be a wire or cord, as shown in the figures - or an equivalent known element, for example smooth or toothed belts and so forth, - to which said thread-guide 12 is fixed with a plug 42 which slides along the rod 13.
  • index "a” indicates the element on the left and index “b” the element on the right, the right and left elements being symmetrical and specularly equal to each other.
  • the flexible element 15 is typically moved by two driving pulleys 16a, 16b activated in an alternating clockwise/anticlockwise movement according to the arrows, each with its own electric motor 17a, 17b, both of said motors being piloted in frequency by a control unit, not shown in the figure for the sake of simplicity, which coordinates the movement of the two motors of the device 14, in a known way, to create the desired transversing movement and keep the flexible element 15 tensioned for its whole length.
  • These motors driven in frequency to move with an alternating and coordinated movement with a piloted angular excursion are known in the art.
  • synchronous motors (17a, 17b) are used, of the so-called brushless or step-by step type, coordinatingly piloted by a control unit of the yarn winding station.
  • the ends of the cord 15 are wound onto the two driving pulleys 16a, 16b, to which they are physically constrained by means of the balls 19a, 19b housed in the respective cavities 20a and 20b.
  • Two pulleys 30a, 30b are coaxially housed on the driving pulleys 16a, 16b, onto which two flexible transmission elements 31a, 31b, for example cords or belts, are hooked and wound by means of the constraints 32a, 32b to one of their ends.
  • the flexible elements 31a, 31b are connected to two elastic spring elements 18a, 18b which are fixed to the structure of the machine.
  • These elastic elements 18a, 18b which always operate under tension, tend to rotate the pulleys 30a, 30b and with them the pulleys 16a, 16b respectively, in the opposite direction, the latter tending to pull the thread-guide 12 each from its own part, keeping the cord 15 under tension.
  • One of the characteristics of the device 14 lies in the fact that, even without the action of the motors 17a, 17b, the device tends to keep the cord 15 suitably tense and bring the thread-guide 12 back towards the centre of its back-and-forth run, in the point where the forces exerted by the springs 18a, 18b are equal and contrary.
  • the combined movement of the two motors, of which the motor 17a pulls, whereas the motor 17b coordinatingly follows with a slight delay, in order to keep the cord 15 suitably tense causes the thread-guide 12 to advance towards the left, by means of the respective pulleys 16a and 16b, rigidly fitted onto the driving shafts.
  • the motor 17a increases its driving torque to overcome the gradual increase in the force of the opposite spring 18b, or more specifically the difference in load between the two springs, i.e.
  • the two motors 17a, 17b are contemporaneously stopped and brought back to velocity in the opposite direction with the maximum torque available which, under the maximum winding velocity conditions, can be obtained by giving the motors an overcurrent also equal to 4 or 6 times the nominal value.
  • the braking and restarting action of the motors is coadjuvated by the elastic energy accumulated by the spring 18b, or better by the difference in energy between the two springs 18b and 18a, which forces the thread-guide 12 to brake and restart it in the opposite direction.
  • the invention envisages that the springs 18a, 18b be structured so that in the inversion point they have an energy available which is such as to brake the thread-guide 12 and restart it in the opposite direction with an acceleration close to or higher than the maximum acceleration which every single motor is capable of supplying to the system consisting of the motor, the respective pulley and other parts connected thereto.
  • the thread-guide 12, whose mass or inertia is not indifferent is the only part not symmetrically positioned and rigidly connected to the two motors. In this way, with each inversion the maximum torque of each motor is available, so that the motor which follows, in the case in question the motor 17a, cannot surpass the opposite motor, consequently slowing down the cord 15.
  • the thread-guide 12 moves from left to right with the pre-established velocity, up to the centre of the run, under the action of the two motors which coordinatingly cause the thread-guide 12 to advance, controlling the decreasing elastic energy of the springs 18a and 18b.
  • the cycle restarts symmetrically as described above.
  • the synchronous motors 17a, 17b are controlled by means of respective position detectors, such as encoders for example, which allow the control unit of the winding unit to reveal the position of the motors and consequently the thread-guide 12: on the basis of the position indications, the control unit coordinatingly controls and drives the two motors 17a, 17b with the relative variable frequency current generators, currently called inverters, to ensure the movement of the thread-guide 12 and at the same time to keep the appropriate tensioning of the cord 15, both under regime conditions and during the start-up, rest or stoppage phase of the collection unit.
  • position detectors such as encoders for example
  • Figures 2A and 2B illustrate an alternative embodiment of the technical solution of figure 1 , with springs subjected to torsion stress instead of traction.
  • Figure 2A synthetically illustrates the connection scheme between motor and torsion elastic elements in a front view
  • figure 2B shows the side view of the left torsion spring, of index "a”: torsion spring 22a with cylindrical winding and with a thread having a round section.
  • torsion springs 22a, 22b are inserted, having, as illustrated in the side view on the left of figure 2B , with particular reference to the left-hand elements, index "a", of the thread-guide device 14, one of the ends 23a, 23b constrained to the driving shaft 45a, 45b and the other end 24a, 24b constrained to the structure of the motor itself 17a, 17b.
  • the two ends of the cord 15 are fixed to the throat of the driving pulleys 16a, 16b with the constraint 26a, 26b.
  • the torsion springs 22a, 22b operate completely analogously to the scheme of figure 1 , referring to the torsion instead of traction stress, and the functioning of the thread-guide device 14 occurs as described for the device represented in the same figure 1 , with the only difference that the springs act directly on the driving shafts.
  • figures 2A and 2B represent the alternative with a torsion spring having a cylindrical winding and with a thread having a round section and a spring applied on the rear side of the motors
  • completely similar and equally functional alternative solutions are in any case possible, for example with springs with a thread having a rectangular section, and/or with spiral winding, and/or applied on the front side of the respective motor, said alternative forms being completely equivalent to that shown.
  • figure 3 illustrates a variant of the solution schematically represented in figure 1 with a second alternative use of torsion springs.
  • the constraint between the cord 15 and driving pulleys 16a, 16b is completely analogous to the scheme of figure 1 , whereas the embodiment of the accumulation and elastic energy release device is different.
  • Two pulleys 30a, 30b are coaxially joined to the two driving pulleys 16a, 16b on which two flexible transmission elements 31a, 31bm, for example belts or cords, are hooked, as in the case of the solution represented in figure 1 .
  • the cords 31a, 31b are connected, with the constraints 32a, 32b, to two levers 34a, 34b oscillating around pins 35a, 35b, and preferably oscillating around axes parallel to those of the pulleys 16a, 16b.
  • the oscillating levers 34a, 34b are connected to two torsion springs - better shown in the subsequent figure 4B as springs 38a, 38b - which are elastically loaded and accumulate elastic energy increasing their torsion when the homologous pulley 30a, 30b is rotated for winding its cord 31a, 31b for the rotation of its motor 17a, 17b, and which are unloaded by releasing their elastic energy untwisting themselves when the homologous pulley 30a, 30b is rotated to release its cord 31a, 31b, supplying at least the necessary torque for restarting the thread-guide 12 with a higher acceleration than that for each single motor 17a, 17b with the respective pulleys.
  • Figures 4A , 4B illustrate a further perfected and preferred embodiment of the thread-guide activation device according to the scheme of figure 3 .
  • this perfected embodiment is shown in a front view and corresponds to that of figure 3 , with the modification of the winding pulleys of the cords 31a, 31b.
  • Said pulleys 40a, 40b are produced with a substantial eccentricity with respect to the axis of the driving pulleys 16a, 16b, adopting the minimum value of the application arm of the force exerted by the cords 31a, 31b on their pulley 40a, 40b in correspondence with the centre point of the thread-guide run 12 and the maximum value of said arm in correspondence with the end points 41a, 41b of the excursion of the thread-guide 12.
  • FIG. 4B shows a sectional side view of the device according to the invention with greater details of its functioning.
  • the winding bobbin 10 is sustained by counter-points 43a, 43b of the bobbin-holder arm to rotate in a clockwise direction for contact with the activation roll 11.
  • the yarn F comes from below, diverted by the distancing rod 44, and is wound onto the bobbin 10, distributed on the surface of the bobbin by the thread-guide 12, which moves with a back-and-forth movement parallel to the axis of the roll 11 and along the guiding rod 13.
  • the spring 38a is a torsion spring having an end 39a constrained to rotate with the pass-through pin 35a of the lever 34a, loading and unloading the torsion, whereas the other end 40a is constrained to the structure 41 of the machine.
  • Figure 5 illustratively illustrates the trend of the return force exerted by the elastic energy accumulation device on the thread-guide 12 with the cord 15 with a variation of the anticlockwise excursion of the pair of levers 34a, 34b which are tilted towards the left, whereas the thread-guide 12, on the other hand, goes from the centre towards the right, position "0" being the central rest position of the thread-guide and position "10" the extreme movement inversion position.
  • the trend of the return force in the clockwise excursion of the levers 34a, 34b and the return towards the left of the thread-guide is specularly equal to the other part.
  • the overall inertia of the system is lower due to the use of an open flexible element, i.e. a flexible element having reduced dimensions and a smaller mass.
