Definitions

  • the present invention relates to a winding method and that device for the preamble of claims 1 and 8, respectively.
  • the winding unit 1 of a known autowinder is arranged such that a package P of predetermined shape is formed by winding yarn Y on a take-up tube 3 from a spinning bobbin (not shown in the drawing) arranged on the lower part while traversing is being carried out by a traverse drum 2.
  • the traverse drum 2 is arranged so as to be rotated while supported on one side only on a frame 4 of the winding unit 1.
  • a cover 6 in order to prevent the yarn Y from flying from the groove 5 is arranged on the front side of the traverse drum 2 and a guide member 7 for restricting the running of the yarn Y corresponding to the traverse width is arranged in front of that.
  • the guide member of this type may be adjustable in accordance with the kind of yarn, the winding speed and other conditions as disclosed in JP-A-63306166.
  • a slub catcher 8 that detects yarn defects (slub) in the yarn Y and cuts the yarn is arranged upstream in the yarn running direction from the guide member 7.
  • a tension device for applying a suitable tension to the yarn Y and a suction mouth and suction pipe for transferring the upper yarn and lower yarn to the knotter by rotating during yarn piecing and the like are arranged on the winding unit 1.
  • the yarn Y when performing winding of the yarn Y by this kind of the autowinder, the yarn Y sometimes becomes separated from the package P (end missing ) and yarn bundles on the outer layer of the package P sometimes lips to the small diameter side (scramble) resulting in a defective package.
  • end missing one cause is the unrestricted flying of the yarn due to the sudden decrease in tension when the yarn breaks or when the supply yarn runs out due to the lastly wound part of the spinning bobbin.
  • scramble one cause is the instability of the yarn Y tension when winding starts after yarn piecing.
  • the object underlying the invention is the prevention of the generation of defective packages by tension decreases and an increase in the package quality.
  • Figure 1 is front view showing a first embodiment of the present invention.
  • Figure 2 is a plan view of the main part of Figure 1.
  • Figure 3 is front view showing a second embodiment of the present invention.
  • Figure 4 is a plan view of the main part of Figure 3.
  • Figure 5 is a drawing showing the change in drum speed for describing the actions of Figure 4.
  • Figure 6 is a front view of the main part of an autowinder being a conventional winding device.
  • Figures 1 and 2 show an autowinder utilizing the winding method and that device being a first embodiment of the present invention.
  • a winding unit 11 of this autowinder is provided with a traverse drum 2 for winding a yarn Y from a spinning bobbin (supply yarn bobbin) 12 while performing suitable traversing and is arranged such that a package P of predetermined shape (cone shape) is formed while removing yarn defects by a slub catcher 13.
  • the traverse drum 2 is supported on one side on the frame 14 of the winding unit 11 and makes the package P rotate by friction contact by the rotation of a drum motor (not shown in the drawings).
  • a groove 5 for traversing the yarn Y at a predetermined width A is formed in the peripheral surface of the traverse drum 2 and a cover 6 is arranged in front of that for preventing the yarn Y from flying out of the groove 5.
  • a yarn restriction member 15 is arranged below (upstream in the yarn running direction) the traverse drum 2.
  • the yarn restriction member 15 comprises a pair of lever plates 16, 17 which are able to swivel freely arranged along the axial direction of the traverse drum 2.
  • a drive system 18 for driving these lever plates 16, 17 at predetermined timings is provided.
  • the lever plates 16, 17 are supported via vertical shafts 19, 20 on a support bracket (not shown in the drawings) mounted on the frame 14 and the side where the tip swivels extends more forward than the traverse drum 2.
  • Indented contact parts 21, 22 are formed on the inside edge of those extending parts in order to suitably contact with the yarn Y.
  • the contact parts 21, 22 which contact with the yarn Y form the yarn restriction member 15 being essentially the present invention.
  • a link lever 23 spans from the near basal end of the vertical shaft 19 of one lever plate 16 positioned at the small diameter side of the package P to near the tip end of the vertical shaft 20 of the other lever plate 17 positioned at the large diameter side and is supported so as to be able to rotate on both ends by a pin 24.
  • the swivelling of one lever plate 16 is transmitted to the other lever plate 17 and the lever tips separate or close together.
  • angled surfaces 32, 33 being a shape consisting of two converging lines separated at the top when viewed from above are arranged on the lever plates 16, 17 more toward the tip than the contact parts 21, 22 and are able to contact with the yarn (the end of the yarn which has begun to fly up) further in front of the yarn path during normal winding.
  • the drive system 18 comprises an air cylinder 25 connected to one lever plate 16, an electromagnetic valve 26 for supplying or expelling the air for operation of the air cylinder 25, and a controller 27 for suitably operating the electromagnetic valve 26.
  • the air cylinder 25 is arranged in the axial direction of the traverse drum 2 and is coupled to the basal end of one lever plate 16 via a vertical pin 30 of a linking tool 29. In short, the air cylinder 25 extends when air is supplied and causes the pair of lever plates 16, 17 to swivel towards each other.
  • the projection distance of the contact part 21 of one lever plate 16 is arranged to be greater than the projection distance of the contact part 22 of the other lever plate 17.
  • the traverse restriction amount L 1 (the distance the contact part 21 projects into the traverse range A) of the small diameter side is 35mm
  • the traverse restriction amount L 2 (the distance the contact part 22 projects into the traverse range A) of the large diameter side is 30mm.
  • the traverse restriction amount L 1 of the package small diameter side of the yarn restriction member 15 is larger than the traverse restriction amount L 2 of the package large diameter side of the yarn restriction member 15 (L 1 >L 2 ). This is a countermeasure as end missing tends to more easily occur on the small diameter side as the peripheral surface of the cone shaped package P is in a downwards slanting state toward the small diameter side.
  • the operations of the electromagnetic valve 26 can be executed first and a position approximately 50cm from the slub detection place can be cut even at a yarn speed of 1,300m/min and accordingly, this does not present any hindrances to removal of the yarn defect.
  • the package P is separated from the drum 2 by a no-yarn detection signal from the slub catcher 13.
  • a balloon controller 28 shown in Figure 1 In order to perform operations when the supply yarn 12y runs out, operations of a balloon controller 28 shown in Figure 1 are used.
  • the balloon controller 28 restricts the balloon whenever there is unwinding of the spinning bobbin 12 and if the supply yarn 12y of the spinning bobbin 12 becomes scarce, the balloon length is prevented from becoming too long by moving downwards.
  • a gate feeler 31 is also used for controlling.
  • the gate feeler 31 determines whether to carry out a bobbin exchange by detection of whether there is a lower yarn (supply yarn) or not when there is a yarn breakage or when the yarn is cut. An absence of yarn is detected by the gate feeler 31 at almost the same time as when unwinding of the supply bobbin 12 is complete. Accordingly, by inputting this no-yarn signal c in the controller 27, yarn restriction may be performed by swivelling of the lever plates 16, 17 immediately before flying of the yarn end.
  • the upper yarn (package P yarn) is easily picked up by the yarn picking means (suction mouth) when yarn piecing occurs and the success rate of auto-yarn piecing can be improved.
  • lever plates 16, 17 and that drive system 18 shown in the present embodiment can be simply arranged on a pre-installed auto-winder due to their simple structure and show extremely high utility.
  • traverse restriction may be performed even when the yarn naturally breaks.
  • knotting is performed but maintaining the traverse restriction by the lever plates 16, 17 during this knotting and gradually opening while increasing the rotation of the traverse drum 2 and then removal of the restriction, is also possible.
  • the tension can be increased during the period of tension instability when winding starts after knotting and mis-traversing where the yarn Y separates from the groove 5 of the traverse drum 2 can be prevented. Loose winding by a decrease in tension can also be prevented.
  • this scramble can be prevented if a traverse restriction is performed, for example, for 6-7 seconds from the start of rotation of the 10 second slow start period.
  • the present invention is able to improve package quality as traverse restriction is performed when the yarn tension decreases to a level which affects the quality of the package P.
  • a pair of lever plates 16, 17 are shown as a yarn restriction member 15 but if able to restrict the yarn path to the center, any construction is suitable.
  • the drive system 18 is not limited to the air cylinder 25 but may be any such construction that operates the yarn restriction member 15 by a predetermined timing.
  • Figures 3 and 4 show an autowinder utilizing the winding method and that device being a second embodiment of the present invention.
  • a winding unit 111 of this autowinder is provided with a traverse drum 102 for winding a yarn Y from a spinning bobbin (supply yarn bobbin) 112 while performing suitable traversing and is arranged such that a package P of predetermined shape (cone shape) is formed while removing yarn defects by a slub catcher 113.
  • the traverse drum 102 is supported on one side on the frame 114 of the winding unit 111 and makes the package P rotate by friction contact by the rotation of a drum motor 134.
  • a groove 105 for traversing the yarn Y at a predetermined width A is formed in the peripheral surface of the traverse drum 102 and a cover 106 is arranged in front of that for preventing the yarn Y from flying out of the groove 105.
  • a yarn restriction member 15 is arranged below (upstream in the yarn running direction) the traverse drum 102.
  • the yarn restriction member 115 comprises a pair of lever members being lever plates 116, 117 which are able to swivel freely arranged along the axial direction of the traverse drum 102.
  • a drive system 118 for driving these lever plates 116, 117 at predetermined timings is provided.
  • the lever plates 116, 117 are supported via vertical shafts 119, 120 on a support bracket (not shown in the drawings) mounted on the frame 114 and the side where the tip swivels extends more forward than the traverse drum 102.
  • Indented contact parts 121, 122 are formed on the inside edge of those extending parts in order to suitable contact with the yarn Y.
  • the contact parts 121, 122 which contact the yarn Y form the yarn restriction member 115 being essentially the present invention.
  • a link lever 123 spans from near the basal end of the vertical shaft 119 of one lever plate 116 positioned at the small diameter side of the package P to near the tip end of the vertical shaft 120 of the other lever plate 117 positioned at the large diameter side and is supported so as to be freely rotatable on both ends by a pin 124. In short, the swivelling of one lever plate 116 is transmitted to the other lever plate 117 and the lever tips separate or close together.
  • angled surfaces 132, 133 being a shape consisting of converging line with the ends top end separated when viewed from above are arranged on the lever plates 116, 117 more toward the tip than the contact part 121, 122 and are able to contact with the yarn (the end of the yarn which has begun to fly up) further infront of the yarn path during normal winding.
  • the drive system 118 comprises an air cylinder 125 connected to one lever plate 116, an electromagnetic valve 126 for supplying and expelling the air for operation of the air cylinder 125, and a controller 127 for suitably operating the electromagnetic valve 126.
  • the air cylinder 125 is arranged in the axial direction of the traverse drum 102 and is coupled to the basal end of one lever plate 116 via a vertical pin 130 of a linking tool 129. In short, the air cylinder 125 extends when air is supplied and causes the pair of lever plates 116, 117 to swivel towards each other.
  • traverse restriction may be performed continuously from knotting up to and after when the drum starts by swivelling of the lever plates 116, 117 during knotting (being when the spinning bobbin yarn and package yarn are joined including yarn piecing by air).
  • the yarn picking means suction mouth
  • the yarn picking means easily picks the upper yarn (package P yarn) during yarn piecing and the auto-yarn piecing success rate improves.
  • lever plates 116, 117 and that drive system 118 shown in the present embodiment can be simply arranged on a pre-installed auto-winder due to their simple structure and show extremely high utility.
  • this yarn restriction member 115 may also be used to prevent end missing. It is believed that the flying of the yarn Y due to a sudden loss of high tension due to a cut yarn Y is one cause of end missing. Accordingly, not only when winding starts, but also when the yarn is cut by the slub catcher 113 and when supply yarn 112y of the spinning bobbin 112 runs out, traverse restriction is performed. In order to drive the lever plates 116, 117 by this timing, a yarn defect detection signal is input from the slub catcher 113 shown in Figure 4 into the controller 127 and before the cutter provided on the slub catcher 113 operates, the air cylinder 125 operates by switching of the electromagnetic valve 126.
  • the operations of the electromagnetic valve 126 can be executed first and a position approximately 50cm from the slub detection place can be cut even at a yarn speed of 1,300m/min and accordingly, this does not present any hindrances to removal of the yarn defect.
  • a balloon controller 128 shown in Figure 3 In order to perform operations when the supply yarn 112y runs out, operations of a balloon controller 128 shown in Figure 3 are used.
  • the balloon controller 128 restricts the balloon whenever there is unwinding of the spinning bobbin 112 and if the supply yarn 112y of the spinning bobbin 112 becomes scarce, the balloon length is prevented from becoming too long by moving downwards. Accordingly, when the balloon controller 128 has been moved to the lowest position, this is detected by a sensor or the like and when this detection signal enters the controller 127 or after a predetermined time has elapsed after receiving this signal, traverse restriction can be performed immediately before the supply yarn 112y runs out if the lever plates 116, 117 are swivelled.
  • a gate feeler 131 may also be used for controlling the prevention of end missing.
  • the gate feeler 131 determines whether to carry out a bobbin exchange by detection of whether there is a lower yarn (supply yarn) or not when there is a yarn breakage or when the yarn is cut. An absence of yarn is detected by the gate feeler 131 at almost the same time as when unwinding of the supply bobbin 112 is complete. Accordingly, by inputting this no-yarn signal in the controller 127, yarn restriction may be performed by swivelling of the lever plates 116, 117 before flying of the yarn end.
  • the projection distance of the contact part 121 of one lever plate 116 is larger than the other lever plate 117. This is a countermeasure as end missing tends to easily occur on the small diameter side as the peripheral surface of the cone shaped package P is in a downwards slanting state toward the small diameter side.
  • a pair of lever plates 116, 117 are shown as a yarn restriction member 115 but if able to restrict the yarn and change the tension, any construction is suitable.
  • the drive system 118 is not limited to the air cylinder 125 but may be any such construction that operates the yarn restriction member 115 by a predetermined timing.
  • the yarn restriction member is arranged of a pair of lever members pushing the yarn towards the center, the device construction may be simplified and application on a pre-existing auto-winder is possible providing high utility.
