Definitions

  • the present invention relates to a splicer device for splicing yarns during the winding thereof on a tube in order to achieve the formation of collection packages of the yarn produced or processed by textile machines.
  • the present invention relates to a winding machine comprising such a splicer device too.
  • the yarn collection technique rotatably actuating a tube, idly carried by the spindles of a package-holder arm and drawing back the yarn coming from a follower to wind thereon.
  • the package is thus formed by pulling and winding the yarn on the surface thereof, being rotatably dragged with an underlying motor-driven roller on which the package itself rests.
  • the yarn may be wound at a constant linear speed, independent of the size taken by the package as the winding advances, and only as a function of the rotation speed of said actuating roller.
  • winding machines consist of a plurality of winding stations or units aligned along the front of the machine and provided with common service apparatuses.
  • the winding unit is shown in its essential components in Figure 1 which illustrates a front view thereof.
  • the feeding bobbing 1 is unwound by drawing its yarn 2.
  • the yarn 2 passes through the uncoiling assembly 3, which comprises yarn containment and driving members and a yarn detector, and thus through the yarn tensioner 5 which makes the path of the yarn 2 more or less tortuous and determines the tension thereof.
  • the splicer 6 is found, to which the yarn ends are taken that have to be joined by suction inlets 9 and 10 from the feeding bobbing- and the package-side, respectively.
  • inlet 9 takes the yarn end from the feeding bobbing-side to the splicer 6 and inlet 10 draws the yarn end upwards by drawing it from the package to take it downward and insert it in the splicer.
  • inlet 10 draws the yarn end upwards by drawing it from the package to take it downward and insert it in the splicer.
  • Such inlets operate frequently, both upon yarn interruptions due to the breaking thereof or to the intervention of the following yarn clearer 11, which is located downstream of the splicer 6, and to the depletion of the feeding bobbing 1.
  • the packaged yarn is collected into the package 12, which is rotatably actuated by the actuating cylinder 13, whereon it rests supported by the package-holder arm 14.
  • each winding station depletes a large number of feeding bobbings to form greatly larger-sized packages.
  • a feeding bobbing is depleted in a few minutes, while a package is completed in a little less than one hour.
  • Each feeding bobbing depleted is replaced with a new feeding bobbing, then carrying the yarn 2 thereof to join with the yarn end coming from the package.
  • a feeding bobbing handling system is placed, which feeds the new feeding bobbings to be unwound and discharges the tubes of depleted feeding bobbings, handling even thousands of items per hour.
  • the yarn winding processing consists of the cleaning of the yarn by eliminating defective portions, which are detected and eliminated with the interventions of the yarn clearer 11, then by splicing or joining the two ends of the yarn with the splicer 6 and resuming the unwinding of the feeding bobbing 1.
  • the quality of the yarn produced with the winding therefore depends on the selection carried out by the yarn clearer and the splicing achieved by the splicer 6.
  • the requirements needed for the splicing carried out by the splicer are of a mechanical nature, in terms of splicing resistance, of an aesthetic nature, since the splicing should not be distinguishable along the yarn, and of reliability, in terms of performance consistency of the splicers which equip the winding units.
  • the two ends are prepared with air blows to be refined eliminating a part of their fibers, so that the two ends to be superimposed are untwisted and their fibers are made parallel.
  • Such operation is carried out in a conduit and by subjecting the yarn end to the action of compressed air blown in the direction consistent with the end of the yarn to be refined,
  • US patent 6,199,360 discloses the actuation of the various members of the splicer with a piston valve which slides and sequentially distributes compressed air to the various members of the splicer.
  • Patent applications WO 2006/42721 and 2007/76908 disclose coordinated actuating means of the pneumatic splicer.
  • the technical problem to which the present invention is directed is the controlled actuation of such movements of the splicer 6 in the various steps of the splicing process by simplifying both the device and the process in terms of movements and synchronisms.
  • Figure 1 shows the scheme - in front view - of the yarn collecting unit in a winder, wherein there are indicated the most significant members which take part in the package formation process and is illustrative of the technical problem.
  • Figure 2 show the steps of the yarn splicing process with the splicer device according to the present invention, with reference to the exploded view of the essential components thereof.
  • Figure 2A shows the splicer device in the initial step 1, wherein the yarn ends are brought to the splicer from the package-side and feeding bobbing-side inlets, wherein the following items are shown in exploded view:
  • clamping members which receive and retain the yarn of the package 12 carried by inlet 10 and the yarn of the feeding bobbing 1 carried by inlet 9, respectively.
  • Such clamping members are secured onto plates 20,21 and placed inside the gap between said plates,
  • the 30,31 upper and lower yarn end preparation chambers for the preparation of the feeding bobbing-side yarn end and package-side yarn end, respectively. They consist of conduits wherein air is blown at high speed which refines the yarn end. Halfway of each conduit 30,31 a passage 32,33 is made for the input and output of the yarn end being processed.
  • the upper preparer 30 processes the yarn end coming from the feeding bobbing 1 blowing to the right and discharging air according to arrow S.
  • the lower preparer 31 processes the yarn end coming from the package 12 blowing to the left and discharging air according to arrow R.
  • the splicing chamber 35 splicing chamber of the ends of the yarn 2; according to an embodiment said splicing chamber 35 performs pneumatic splicing of the yarn with compressed air; according to other embodiments of the present invention, the splicing chamber 35 performs yarn splice by other means;
  • the inlets 9 and 10 take the two yarn ends to the splicer 6.
  • the feeding bobbing-side inlet 9 carries the yarn end to enter, guided by the guiding slot 22, firstly the cavity of the splicing chamber 35 and then the open upper shears 28.
  • the package-side inlet 10 carries the yarn end to enter, guided by the guiding slot 23, firstly the cavity of the splicing chamber 35 and then the open lower shears 29.
  • Figure B shows the splicer device in step 2, wherein the yarn ends brought to the splicer from the package-side and feeding bobbing-side inlets are introduced in the clamps 24,25 with the clockwise rotation of levers 38 and 39, which with their end cavities 40 and 41 carry the two yarn ends to also enter, guided by the guiding slot 22, the clamps 24,25 still open.
  • the lid 36 closes back. Therefore, the clamps 24,25 are closed with the two yarn ends still suctioned by inlets 9 and 10.
  • the lid 36 is not shown as completely closed in order to clearly show the position of the yarn ends being processed.
  • FIG. 2C shows the splicer device in step 3, wherein the yarn ends are held by the clamps 24,25 and closed in the lid 36.
  • Step 3 consists of the cut of the yarn ends with the shears 28 and 29: yarn segments are suctioned with the inlets 9 and 10. Once the yarn ends have been cut, said inlets are no longer needed and may be taken to a stand-by position.
  • FIG. 2D shows the splicer device in step 4, wherein the yarn ends are still held by the clamps 24,25 and closed in the lid 36.
  • Step 4 consists of a second clockwise advance of the levers 38 and 39 to determine the yarn length to be introduced in the preparers 30 and 31.
  • Step 5 shows the splicer device in step 5, wherein the yarn ends are still held by the clamps 24,25 and closed in the lid 36.
  • Step 5 consists in the refining of the yarn ends untwisting them and eliminating the shortest part of their fibers, so that the processed yarn ends globally have the same number of fibers as the entire yarn, with modes per se well known to those skilled in the art.
  • Such operation is carried out in the preparers 30 and 31 wherein compressed air is blown in the S and R directions.
  • the two yarn ends are thus suctioned by the air stream and enter, with openings 32 and 33, their preparer 30 and 31, wherein they are processed by a determined length with step 4.
  • FIG. 2F shows the splicer device in step 6, wherein the yarn ends are still held by the clamps 24,25 and closed in the lid 36.
  • Step 6 firstly consists of a third clockwise advance of the levers 38 and 39 to carry inside the splicing chamber the yarn end segments which have been prepared in step 5 and to determine the length of their superimposition in the splicing chamber 35. A proper splicing is therefore achieved by blowing compressed air in the chamber 35, with modes per se well known to those skilled in the art.
  • Figure 2G shows the splicer device once the operation is complete: all the assemblies return to a stand-by position.
  • the clamps 24 and 25 as well as the shears 28 and 29 are open.
  • the levers 38 and 39, as well as the lid 36, are rotated counterclockwise releasing the joined yarn 2, which exits the chamber 35 and cavities 22,23. Winding of the yarn 2 from the feeding bobbing 1 to the package 12 may be resumed.
  • a remarkable feature of the present invention lies in that the synchronism of the initial movements of clamping and cutting to size of the yarn ends is made possible by a single control for both yarn ends, as is shown with reference to the exemplary embodiment of figures from 3 to 5.
  • Figure 3 shows the structure of the common actuating device of the clamps and shears of the splicer device according to the invention, with reference to the device installed onto the upper plate 20 and driven with the actuator 50, having the shears 28 placed over the plate and the clamp 24 under the plate.
  • the same device is installed onto the lower plate 21 and driven with the actuator 51, but is made with a mirror construction, that is with the shears 29 placed under the plate and the clamp 25 over the plate.
  • the relative position of the two clamping and cutting members may also be achieved in a different way, for example, conversely, with the clamps on the outside of the plates and the shears on the inside, or with the two members on the same side of the plate thereof.
  • said actuators 50,51 comprise cylinders, for example pneumatic cylinders.
  • said cylinders may also be hydraulic cylinders.
  • said actuators 50,51 may comprise electric devices, for example electric motors and so on.
  • Figure 3A shows the actuating device in a stand-by condition, that is with the clamp and the shears open.
  • the actuating device comprises a pneumatic cylinder 50 which extends and retracts a stem 53, which causes lever 55 to move pivoted on the lower face of the plate 20 with a fixed pin 56 and which can rotate according to arrow A.
  • the end part of the stem 53 is pivoted on lever 55 with a moving pin 57.

  • the end part of the stem 53 with its moving pin 57 is connected to lever 65 with the insertion of such pin 57 in a slot or hole 68 made in the body of the second lever 65, so that the first part of the stroke of the stem 53 does not cause the rotation of lever 65 and that with the second part of the stroke the pin 57 reaches the bottom of the slot 68 and causes the rotation of the same lever according to arrow B.
  • Lever 65 is installed above the plate 20 and its rotating end 69 makes up the cutting moving part of the shears 28 which corresponds to the abutment fixed part 70, mounted onto the plate 20.
  • Figure 3B shows the actuating device in a clamping step, that is with clamp 24 only closed, leaving the shears 28 open.
  • the pneumatic cylinder 50 extends the stem 53 by a first feed segment, which causes lever 55 to rotate according to arrow A. Its rotating end 59 rotates until it meets the fixed abutment anchor 60 and closes clamp 24, with the dampening from the springs 62.
  • the end moving pin 57 of the stem 63 goes through the slot 68 and does not cause the rotation of lever 65 according to arrow B.
  • the shears 28 remain open.
  • Figure 3C shows the actuating device in a cutting step of the yarn ends, that is also with the closing of the open shears 28.
  • the pneumatic cylinder 50 extends the stem 53 by a second feed segment, which causes lever 55 to further rotate according to arrow A. Its rotating end 59 rotates further against the fixed abutment anchor 60 and compresses the springs 62, still with clamp 24 closed.
  • the end moving pin 57 of the stem 53 has completed its path in the slot 68 and rests at the bottom thereof, causing the rotation of lever 65 according to arrow B.
  • the shears 28 close: their rotating end 69 rotates according to arrow B up to their fixed abutment part 70, mounted onto plate 20.
  • Said upper and lower actuators 50,51 are fed in parallel by a feeding device 76 which is common to the two upper and lower actuators 50,51 themselves.
  • pneumatic actuating cylinders 50 and 51 are fed in parallel with a feeding device 76, for example a feeding valve 76, which is common to the two upper and lower devices.
  • a feeding device 76 for example a feeding valve 76, which is common to the two upper and lower devices.
  • the structure of the pneumatic actuating device - which anyway causes the clamping of the yarn end to take place before they are cut to size - ensures the control of their length during the following steps of the process.

  • a half-stroke by-pass conduit is interposed between the two pneumatic cylinders 50 and 51, to make sure that the cutting is only made when the two clamps are closed to block the yarn end thereof.
  • FIGs 4A , B, C show the actuating scheme of the two upper and lower cylinders 50 and 51.
  • a piston 75 slides to which the stem 53 is connected which sequentially actuates clamps and shears.
  • the piston 75 is shown in its three positions: in Figure 4a in initial stand-by position A, in Figure 4B in intermediate clamp closing position B and in Figure 4C in final yarn cutting position C.
  • the piston 75 is pushed from left to right by the air blown with the three-way electrovalve 76.
  • the return stroke from right to left after the yarn ends have been cut, and together with the release of pressure by the electrovalve 76, is instead carried out by a return spring 77, which is loaded in the advance stroke of the piston from left to right.
  • a double effect actuation may be used and in this case the electrovalve may be of the five-way type.
