Definitions

  • the present invention concerns a method and device for spooling yarns, and the wound body thus achieved.
  • the cycle to produce yarns in the classical system for cotton, wool and cut fiber in general provides, after the spinning step, the spooling step.
  • the yarn contained in a series of cops arriving from the spinning machine is wound, generally onto a spool shaped like a truncated cone or cylindrical, so as to form a pack, commonly called a reel, with predetermined size and weight.
  • the yarn wound onto the reel is the method almost universally used to obtain a semi-worked product which can be used more rationally in the subsequent processes, such as doubling, warping, weaving or other, for storing, transporting and selling the yarn.
  • the machine that achieves these packs is generally called a spooler, the pack obtained is the reel and the relative operation is spooling.
  • the yarn contained in the various cops is knotted one after the other.
  • the yarn is subjected to the action of a slub-catcher which, located upstream of the system for winding the yarn, identifies possible defects present in the yarn, cuts the yarn in the defective part and eliminates the segment thus cut.
  • the support, or spool is drawn in rotation due to friction by a winding cylinder, on which it rests with a certain pressure.
  • the winding cylinder can have, engraved on its surface, helical traversing grooves, on which the yarn slides. The latter is thus wound on the supporting spool in spirals, which gradually cross according to the helixes present on the winding cylinder.
  • the formation of the reel with crossed spirals, distributed along the winding zone by using grooved cylinders, has a limit due to the difficulty of controlling the yarn at the points where the travel is inverted and when critical diameters are reached with the formation of overlappings due precisely to the fixed traversing frequency connected to the geometry of the grooved cylindrical.
  • the winding cylinder has no groove and the yarn is displaced longitudinally from one end to the other of the spool by means of the action of a thread-guide member independent of the drawing roller, or traversing device, which with an alternate movement crosses the spirals on the spool.
  • the yarn is deposited in successive circumferential layers on the spool, thus forming a pack with crossed spirals which gradually assumes a truncated cone or cylindrical shape according to the type of support (spool) used, the shape and disposition of the helixes present on the winding cylinder or the type of alternate longitudinal movement performed by the thread guide member.
  • the yarn is also cleaned by means of the slub-catcher which, since it has to cut the yarn in order to eliminate the defect, requires that the reel is stopped and a leading segment of the yarn, wound in the reel, is recovered: this is called the "reel head”. It is necessary to insert the reel head inside a knotting device where it will be joined to a leading segment of the yarn wound on the spool, called the “spool head”, so as to re-establish continuity of the yarn.
  • Spooling is then re-started when the join has been made.
  • this step we have an acceleration of the reel being formed, with possible slipping and damage to the yarn, entailing an increase of the sizes of the reel and consequently of the weight.
  • a first limit is to production.
  • the current level of performance of known spoolers, applied for working wool, cotton, synthetic and artificial fibers, and mixes, does not substantially exceed the following parameters:
  • the compactness and uniformity of winding are decisive in subsequent steps, such as for example in dyeing, due to the resistance that the yarn opposes to the passage of the dyebath; in fact, the inner layer of the traditional reel generally has a more intense and darker color, and affects hundreds of meters of yarn, while the outer part, which is sequential to the inner part and represents the part with the sample dye, consists of thousands of meters of yarn; or in twisting, in order to improve the working performance thereof and the quality of the twisted yarn obtained; or again in sales, in order to optimize packing, transport and storage.
  • the quantity of yarn and the weight of the pack are therefore limited by the variables previously described and by the level of tension which arises on the yarn during the unwinding step, according to the use for which it is intended.
  • this packing condition of the spirals mainly entails:
  • the purpose of the invention is to perfect a method and achieve a device able to overcome the above limits and disadvantages, obtaining the following advantages:
  • Another purpose of the present invention is to obtain a disposition of the spirals which will ensure maximum freedom of movement of the spirals, in both a radial and axial direction, and which will allow to adopt a simplified and cheaper cycle of retraction, volume-giving or dyeing.
  • the Applicant has devised, tested and embodied the present invention to overcome the shortcomings of the state of the art and to obtain these and other purposes and advantages.
  • the spooling method according to the present invention comprises at least a first unwinding step in which the yarn is unwound from a support member, such as for example a spool, a reel or other, and a second spooling step, in which the yarn is disposed in layers according to a desired order.
  • the yarn is disposed inside a containing means in overlapping layers, each of which consists of a plurality of contiguous spirals of yarn distributed substantially according to the variable geometry of the containing means.
  • the spooling device comprises at least a feed unit which unwinds the yarn from the support member, and a forming unit, comprising the containing means and deposition means, configured to distribute the yarn in contiguous spirals according to the geometry of the containing means.
  • a so-called wound body is defined as a spooling element, the layers of which are deposited axially one above the other, and not circumferentially around a physical support as happens in the state of the art; said layers have an identical configuration and are without substantial variations in the diameter, or equivalent diameter if the containing means has a non-circular section.
  • the solution according to the present invention thus allows to discharge the unwinding tension, due to the speed of unwinding of the yarn from the feed spool or reel, using calender means disposed upstream of the distribution means, and/or on the distribution means itself, with the advantage that it is possible to wind and deposit a yarn that has not been subject to any stress during packing.
  • the wound body thus achieved can thus exploit completely the available volumes in the feed creels of the textile machines, for example, weaving machines, knitting machines, retouching machines and dyeing machines, and more generally all processes done downstream of the spooling, with considerable improvements in the performance and relative processing costs.
  • Another advantage is that the yarn is always and continuously between the outside and the inside of the wound body due to the effect of the deposition in spirals, so that during the dyeing step the differences in color are eliminated, due to the passage of the dyebath, which occur between the outer and inner layers of traditional reels.
  • the characteristic deposition in spirals of the yarn allows to ensure the maximum freedom of movement of the spirals themselves, in both a radial and an axial direction, and to adopt a simplified and cheaper cycle to retract, give volume to or dye the yarn, without needing to form hanks and the subsequent unwinding thereof.
  • the dyeing cycle is effected starting directly from the wound body obtained, with qualitative results equal to those of the traditional cycle using hanks.
  • the continuous spirals of yarn are disposed around a first axis of rotation "Y" longitudinal and median with respect to said containing means, and substantially misaligned with respect to a second axis "X" on which the spirals are formed.
  • the misalignment of the two axes X and Y allows to deposit the yarn with a substantially hypo-cyclical trajectory which defines, central to the wound body, a cylindrical space that can be used for the subsequent handling of the wound body.
  • the containing means has a square or rectangular cross section, and consequently has an alternate rectilinear movement with respect to the device that distributes the spirals, or two alternate rectilinear movements orthogonal to each other, and on a plane orthogonal to the plane on which the axis X lies, there will be a deposition of the yarn with a trajectory substantially of the cycloid type, obtaining wound bodies of a cubiform or parallelepiped shape.
  • an accumulation step is provided, in which, by means of super-feed/reserve means, an accumulation store of yarn is created to allow the substantially continuous deposition of yarn in the containing means, even during possible steps to replace the spool and/or to detect and eliminate defects in the yarn.
  • the segment of defective yarn comprised between the spool and the inlet to the super-feed/reserve means, is stopped; the defective yarn is removed, with the yarn being cut in correspondence with the defect and simultaneously the heads of the yarn being captured directly by the super-feed/reserve means; and the heads of the yarn are knotted.
  • the super-feed/reserve means therefore allow not to stop the unwinding of the yarn from the support member as the cylindrical container is changed when the wound body is completed. In fact, during this step feed is stopped to the unit that forms the wound body, but yarn continues to be taken up from the support member in order to form an accumulation of yarn on a drum of the super-feed/reserve unit; this accumulation will later be disposed of when the formation is restarted of the new wound body.
  • downstream of the second spooling step at least a step of pressing and tying is provided, in which the overlapping layers consisting of contiguous spirals of yarn are pressed, discharged from the containing means and tied together for packing.
  • the pressing operation effected according to the present invention does not interfere on the tension of the yarn and does not weaken its mechanical characteristics.
  • the pressing performed allows to increase the density of the wound body, with the advantage that during the forming step the number of layers can be increased for a height of the wound body much greater than that of the desired final height.
  • This advantage is particularly important in subsequent steps: packing, transport and logistics in general: in the dyeing step the dyeing apparatus can be loaded with a greater quantity of yarn, as in the feed devices in the subsequent working steps, the knitting machines, warping machines, weaving machines etc.
  • the speed at which the yarn is deposited can also be increased, for example said speed can be about 2,000 m/min.
  • the present invention therefore overcomes the current limits of spooling speed, due to the tension necessary for winding the yarn onto the reel and the alternate movement of the yarn during the traversing step, thus also reducing production times and costs.
  • a spooling device 10 is installed in a spooling machine 11.
  • the spooling device 10 substantially comprises a feed unit 12 which picks up the yarn 17 from a spinning spool 13, from one or more reels 15, or from one or more so-called wound bodies 16, the latter for example obtained previously with the method and device 10 according to the present invention, a super-feed/reserve unit 26 which forms a store for feeding yarn 17, a forming unit 32 in which the wound body 16 is formed, and a doffing, pressing and tying device 51 which picks up the wound body 16 formed in the forming unit 32 and prepares it for packing and subsequent working steps.
  • the feed unit 12 comprises, in a substantially known manner, a plurality of devices, respectively to control and limit the ballon 19, a tensioner device 20, a thread feeler 21, a knotter 22, a slub-catcher and metering device 23, and possibly a paraffining device 25 and/or thread-gripper.
  • the super-feed/reserve unit 26 comprises an accumulation drum 27, upstream and downstream of which there are two groups of calenders, respectively a pick-up calender 29 and an unwinding calender 30, and a deflection calender 31 which introduces the yarn into the forming unit 32.
  • the super-feed/reserve unit 26 allows to accumulate a determinate quantity of yarn 17 in the accumulation drum 27, so as to define a store of yarn 17 upstream of the forming unit 32.
  • This store allows to feed the forming unit 32 substantially continuously, even when slub-catching operations are carried out, or operations to replace the spinning spool 13, or other operations which normally require the temporary stoppage of the spooling machine 11, thus considerably increasing the performance of the spooling machine 11.
  • an alarm signal is emitted and the movement of the pick-up calenders 29 and the accumulation drum 27 is stopped, while the unwinding calenders 30 continue to feed the yarn 17 to the forming unit 32.
  • the pick-up calenders 29 normally detect the length of the yarn 17 that has passed through from the moment of the signal to the stoppage of the yarn 17, and invert the direction of rotation in order to remove from the accumulation drum 27 the correct quantity of yarn 17, in which the defect is contained, said length having been memorized during the stoppage.
  • two thread-catcher mouths rotate, respectively spool head 24 and reel head 28, intercepting the yarn 17 that is stationary in a position suitable for pick-up.
  • the yarn 17 is cut in a known manner by the slub-catcher device 23 in correspondence with the defective segment, which segment is sucked up and removed by the mouth that catches the reel head 28 before being joined with the spool head.
  • the knotting device 22 makes the knot and the pick-up calenders 29 restart their normal rotation, increasing the speed in order to reconstitute the store of yarn 17 in the accumulation drum 27.
  • the unwinding calenders 30 have fed the forming unit 32 substantially continuously.
  • the forming unit 32 comprises two feed calenders 33, a thread-guide channel 36 rotating around a second substantially vertical axis "X", and having a substantially S-shaped development, a distributor plate 37 associated with the thread-guide channel 36 by means of a connection pin 35, and from whose lower periphery the thread-guide channel 36 faces, and a collector plate 39 substantially facing below the distributor plate 37, and rotating around a first vertical axis "Y", in this case misaligned with respect to the second vertical axis "X". If the containing means does not have a circular section, the collector plate 39 will have an alternate rectilinear movement and/or with two directions orthogonal to each other, on a horizontal plane, as explained hereafter.
  • the collector plate 39 can be disposed in contact, or with a gap of less than the diameter of the yarn 17 being worked, with respect to the distributor plate 37, so as to exert a slight pressure on the yarn 17 also during the deposition of the first spiral and the formation of the first layer of spirals.
  • the thread-guide channel 36 comprises an initial segment coaxial with the second vertical axis "X", a final segment in correspondence with the point where the yarn 17 is distributed, and an inclined intermediate segment which connects the initial segment and the final segment.
  • the entity of the orthogonal projection of the intermediate segment on the plane of the distributor plate 37 represents the radius of rotation of the point of distribution of the yarn 17 on the collector plate 39, and also the radius of each spiral of the wound body 16 being formed.
  • the spirals made can have a diameter either greater than or smaller than the radius of the collector plate 39.
  • the simultaneous rotation of the structure of the distributor plate 37 and the collector plate 39 advantageously in opposite directions, according to the direction of torsion of the yarn 17, and the radius of rotation of the point of distribution, determine the formation of successive layers of spirals of yarn 17, defining a wound body 16 having a substantially cylindrical central hole 42.
  • wound body 16 can have sizes, weight and density much greater than those of known reels 15.
  • the wound body 16 has the spirals distanced from each other by a pitch equal to about 0.25 mm, that is, the same as the diameter of the yarn 17, whereas due to the effect of the slight pressure exerted by the collector plate 39 on the yarn 17 during the distribution step, the diameter of the yarn 17 is reduced, thus allowing to have a number of layers 117 of spirals 116 such as to determine a specific density greater by more than 70+80% with respect to a reel of the same size obtained with the state of the art.
  • the distributor plate 37 advantageously has a lower surface with a mirror finish, so as not to interfere on the yarn 17 deposited, it is provided on the upper part with two calenders 40 to distribute and reduce the tension of the yarn 17, disposed in correspondence with the point of distribution of the yarn 17, and is motorized by means of a drive unit 41 kinematically connected to the thread-guide channel 36.
  • both the thread-guide channel 36 and the drive unit 41 are contained inside a protective casing 34.
  • the distribution calenders 40 receive motion from corresponding conical rollers 65 which roll on a conical circular track 66 associated at the upper part with the distributor plate 37.
  • the conical rollers 65 are coaxial and solid with the calenders 40, so that a revolution of the calenders 40 corresponds with every revolution of the rollers 65.
  • the conical rollers 65 tend to move radially due to the centrifugal force, they overcome the resistance of respective return springs 67, opening the gap between the two calenders 40, and thus allow the yarn 17 to exit due to the centrifugal force.
  • the distributor plate 37 is associated in co-planar manner with a fixed plate 38, also advantageously having the surface in contact with the yarn 17 mirror finished, and having sizes corresponding to those of the collector plate 39.
  • the collector plate 39 advantageously has a high-friction upper surface, for example felted, in order to retain the yarn 17 during the deposition step, and is associated at the lower part with a pneumatic piston 43 which allows it to be selectively moved along the first axis "Y" according to the number of layers of spirals 117 of the wound body 16.
  • connection between the pneumatic piston 43 and the collector plate 39 is made advantageously by means of a connection plate 45, provided with an attachment system that allows the simultaneous rotation or translation of the collector plate 39 around the first axis "Y", together with the pneumatic piston 43.
  • the collector plate 39 and the pneumatic piston 43 are selectively made to rotate by a relative drive unit 49.
  • the collector plate 39 will have the same section as the container 46, it will act with a slight pressure on the yarn 17, exerted by the piston 43 during the collection step, and will have a rectilinear movement such that the spirals of yarn 116 will be deposited with the same pitch or distance from each other, the layer of spirals 117 thus being formed by the alternate movement of the system container 46-collector plate 39.
