Definitions

  • the present invention relates to a yarn winding machine and a yarn winding method.
  • the Unexamined Japanese Patent Application Publication (Tokkai-Hei) No. 9-71367 discloses a technique to prevent what is called bulging when a yarn traversed by a traverse device is wound around a winding bobbin via a contact roller to form a package.
  • a winding angle is increased to reduce the tightening of a yarn layer formed at the initial stage.
  • the Unexamined Japanese Patent Application Publication (Tokkai-Hei) No. 9-71367 further describes a technique to avoid ribbon winding by gradually reducing the winding angle toward winding end so as to prevent a wind number from becoming smaller than 1.
  • the bulging is a phenomenon in which windings of the yarn are stacked to bulge the middle of the end surface of a package.
  • the ribbon winding is a phenomenon in which the yarn travels along the same route on a peripheral surface of the package so as to be over lappingly wound thereon.
  • the ribbon winding may cause various problems; the yarn may slip down along the end surface of the package during traversing, the contact roller may vibrate, or the yarn may be improperly unwound from the package during the subsequent step.
  • the improper yarn unwinding is particularly likely to occur with elastic yarns because the elastic yarn is pulled in a tangential direction with respect to the circular package. Furthermore, the improper unwinding may cause yarn breakage.
  • the wind number N is a numerical value used to predict the occurrence of the ribbon phenomenon.
  • Figure 3 illustrates the definition of the wind number.
  • a rectangle 90 shown in Figure 3 corresponds to a developed surface of a peripheral surface of a package. Positions on the developed surface at which the yarn is wound are denoted by reference characters (a) to (d).
  • reference character D denotes the winding diameter of the package.
  • Reference character S denotes a stroke.
  • Reference character WA denotes the winding angle.
  • Reference character ⁇ DtanWA denotes the distance that the yarn advances on the peripheral surface of the package in the axial direction of the package while the yarn travels one round around the peripheral surface of the package in the circumferential direction.
  • the wind number N of 1 is generally called a critical wind number Nd.
  • Figure 1 is a diagram illustrating a technique to inhibit possible bulging by increasing and reducing the winding angle.
  • Figure 2 is a diagram illustrating problems newly occurring if an attempt is made to inhibit possible bulging by increasing and reducing the winding angle.
  • the axis of abscissa indicates the winding diameter of a package.
  • the axis of ordinate indicates the winding angle.
  • Figure 1A shows winding with no bulging measures taken.
  • Figure 1B shows winding with bulging measures taken as disclosed in the Unexamined Japanese Patent Application Publication (Tokkai-Hei) No. 9-71367 .
  • winding at a constant winding angle WA causes windings of the yarn to be stacked to bulge the middle of the end surface of the package. That is, bulging occurs.
  • the winding angle WA is increased at the initial stage of winding start (when the winding diameter D is small). Then, the density of a yarn layer formed at the initial stage is reduced step by step. Furthermore, at the later stage of winding end (when the winding diameter D is large), the winding angle WA is reduced so that the line of the winding angle WA does not stride over the alternate long and two short dashes line.
  • this winding allows the offsetting between an increase in the density of the yarn layer formed by the stacked windings of the yarn and a decrease in the density of the yarn layer resulting from the increased winding angle WA. Consequently, a package with possible bulging inhibited is formed.
  • the yarn may slip down along the end surface of the package as shown in (c2) in Figure 2C , or the yarn may be improperly unwound as described above.
  • the technique described in the Unexamined Japanese Patent Application Publication (Tokkai-Hei) No. 9-71367 can inhibit possible bulging but may inevitably involve ribbon winding depending on the yarn type.
  • EP-A-1 256 540 discloses a yearn winding machine comprising a contact roller which rotates by contacting to the peripheral surface of the package, a yarn feed roller which is provided to the upstream side of the contact roller with a space from the peripheral surface of the package, and rotates while contacting the yarn to the peripheral surface to supply the yarn to the package, a roller supporting member for supporting the contact roller and the yarn feed roller, and a roller supporting member position adjusting means for adjusting the position of the roller supporting member in the direction the space changes.
  • the contact roller is supported capable of being displaced relative to the roller supporting member in the direction the space changes.
  • the contact roller is supported capable of being displaced relative to the roller supporting member, and a control means is provided for controlling the roller supporting member position adjusting means so that the space is to be constant irrespective of the package diameter.
  • EP-A-1 175 364 discloses a method for winding a continuously fed thread and a device for carrying out this method.
  • the thread is wound on a driven bobbin to form a cross-wound bobbin, whereby the thread is guided in a to-and fro manner within a traversing stroke by a traversing thread guide.
  • the length of the traversing stroke of the traversing thread guide can be changed within the bobbin width of the cross-wound bobbin.
  • the traversing stroke is changed between a maximum length at the start of bobbin travel and a final length at the completion of bobbin travel according to a predetermined stroke function such that, over the course of the bobbin travel, a determined length is assigned to each traversing stroke, whereby the lengths of the traversing strokes are smaller than the respective wound bobbin widths.
  • a main object of the present invention is to provide a technique to prevent possible ribbon winding regardless of the yarn type while inhibiting possible bulging.
  • FIG 4 is a diagram showing the relationship between the free length and a traverse delay.
  • a free length FL (FL1, FL2) shown in Figure 4 refers to the free length of a yarn over which the yarn engaged with a traverse guide in a traverse device travels after being released from the traverse guide and before coming into contact with the peripheral surface of a contact roller.
  • the free length FL can be increased and reduced by moving the traverse guide away from and closer to the contact roller as shown in Figure 4 .
  • the yarn is received on the contact controller at an axial position N1.
  • the traverse delay E is E1. That is, the yarn is wound around the package at a position closer to the axial center of the package than the axial position of the traverse guide by a distance corresponding to the traverse delay E1.
  • the traverse delay E is E2.
  • FIG. 5 is a diagram illustrating a mechanism to inhibit possible bulging utilizing the free length FL.
  • Figure 5A shows winding with the free length FL maintained constant.
  • Figure 5B shows winding with the free length FL varied from FL1 through FL2 to FL1 (FL1 ⁇ FL2). That is, if winding is carried out with the free length FL maintained constant without using the technique disclosed in the Unexamined Japanese Patent Application Publication (Tokkai-Hei) No.
  • the winding width starts to decrease gradually during winding start as shown in the left part of Figure 5B . Then, when the free length FL reaches FL2, the winding width is smaller than a value measured during the winding start, by ⁇ E x 2. Thereafter, the winding width gradually increases toward the winding end. When the free length FL eventually varies back to FL1, the winding width becomes equal to the value measured during the winding start.
  • the cross section of the package is shaped like a saddle-backed shape.
  • the above-described technique allows bulging caused by a winding tightening force resulting from the stacked windings of the yarn to be offset by increasing and reducing the winding width so that the cross section of the package is shaped like a saddle-backed shape.
  • the technique allows possible bulging to be inhibited by increasing and reducing the free length FL.
  • a feature of the above-described technique is that an increase and reduction in free length FL does not cause an undesirable change in wind number N.
  • the technique is advantageous over the Unexamined Japanese Patent Application Publication (Tokkai-Hei) No. 9-71367 .
  • a yarn winding machine that forms a package is configured as follows.
  • the yarn winding machine includes a contact roller configured to come into contact with the package during formation of the package, a traverse device located upstream side of the contact roller in a traveling direction of a yarn, a free length varying means for enabling the free length of the yarn located between the contact roller and the traverse device to be varied during formation of the package, and a control means for controlling the free length varying means in such a manner that the free length is increased during winding start of the package and then reduced toward winding end.
  • This configuration allows possible bulging to be inhibited.
  • an increase and reduction in free length avoids varying the wind number.
  • winding can be easily carried out with possible bulging inhibited and with the critical wind number avoided.
  • Successful avoidance of the critical wind number in turn allows avoidance of various problems: slip-down of the yarn along the end surface of the package during traversing, vibration of the contact roller, and improper unwinding of the yarn from the package during the subsequent step.
  • the winding angle may be maintained constant or increased and reduced similarly to the free length.
  • the above-described yarn winding machine is further configured as follows.
  • the yarn winding machine further includes a winding angle varying means for enabling the winding angle to be varied.
  • the control means controls the winding angle varying means in such a manner that the winding angle is increased during the winding start of the package and then reduced toward the winding end. In this manner, to allow possible bulging to be inhibited, both the free length and the winding angle are increased and reduced. This enables a reduction in the range of an increase and reduction in free length required to inhibit possible bulging. As a result, the free length varying means can be made compact.
  • a second aspect of the present invention provides a yarn winding method of forming a package using a contact roller configured to come into contact with the package during formation of the package and a traverse device located upstream side of the contact roller in a traveling direction of the yarn.
  • the free length of the yarn located between the contact roller and the traverse device is increased during winding start of the package and then reduced toward winding end.
  • This configuration allows possible bulging to be inhibited.
  • an increase and reduction in free length is prevented from changing the wind number.
  • winding can be easily carried out with possible bulging inhibited and with the critical wind number avoided.
  • Successful avoidance of the critical wind number in turn allows avoidance of various problems: slip-down of the yarn along the end surface of the package during traversing, vibration of the contact roller, and improper unwinding of the yarn from the package during the subsequent step.
  • the above-described yarn winding is further carried out by following method.
  • the winding angle is increased during the winding start of the package and then reduced toward the winding end. In this manner, to allow possible bulging to be inhibited, both the free length and the winding angle are increased and reduced. This enables a reduction in the range of an increase and reduction in free length required to inhibit possible bulging.

  • the control section 80 first calculates the winding diameter D of the current package 4 (S300). Specifically, the control section 80 acquires the rotation speed of the contact controller 8 based on a sensing signal from the rotation sensor 40. The control section 80 acquires the rotation speed of the bobbin holder 12 based on a sensing signal from the bobbin holder rotation sensor 35. Based on the rotation speed of the contact controller 8, the rotation speed of the bobbin holder 12, and the diameter of the contact controller 8 pre-stored in the ROM, the control section 80 calculates the winding diameter D of the current package 4.
  • control section 80 calculates an increment ⁇ D in the winding diameter D of the package 4 (S310). Specifically, the control section 80 determines the difference between the past winding diameter D calculated as described in S300 and the current winding diameter D of the package 4 calculated as described in S300 to calculate the increment ⁇ D in the winding diameter D of the package 4.
  • the control section 80 calculates the variation amount ⁇ FL of the free length FL (S330). Specifically, the control section 80 determines the difference between the past free length FL calculated as described in S320 and the current free length FL calculated as described in S320 to calculate the variation amount ⁇ FL of the free length FL.
  • Figure 8 indicates that the variation amount ⁇ FL has positive values while the winding diameter D is varying from D1 to D2. The variation amount ⁇ FL has negative values while the winding diameter D is varying from D2 to D3.
  • the control section 80 calculates the movement amount ⁇ G of the slide box 16 (S340). Specifically, based on the increment ⁇ D in the winding diameter D of the package 4 calculated as described in S310, the variation amount ⁇ FL of the free length FL calculated as described in S330, and Expression 2 shown below, the control section 80 calculates the movement amount ⁇ G (the upward direction of the body frame 5 corresponds to the positive side) of the slide box 16.
  • the ⁇ FL in Expression (2) may take a negative value as described above. Thus, if the absolute value of the variation amount ⁇ FL is larger than ⁇ D, the movement amount ⁇ G has a negative value.
  • control section 80 moves the slide box 16 up and down based on the movement amount ⁇ G calculated as described in S340 (S350). Specifically, the control section 80 drivingly controls the motor 23 so as to elevate and lower the slide box 16 until the height position of the slide box 16 determined based on a sensing signal received from the position sensor 18 varies by the movement amount ⁇ G.
  • the control section 80 determines whether or not the winding diameter D of the package 4 calculated as described in S300 has reached a predetermined value Dmax (S360). If the control section 80 determines that the winding diameter D has not reached the predetermined value Dmax yet (S360: N0), the control section 80 shifts back to the processing in S300. On the other hand, if the control section 80 determines that the winding diameter D has reached the predetermined value Dmax (S360: YES), the control section 80 rotates the turret plate 6, changes the bobbin, and then starts a new winding operation.

  • the axis of abscissa indicates the winding time.
  • the axis of ordinate indicates the height position of the slide box 16.
  • the solid line shows how the height position of the slide box 16 according to the present embodiment varies.
  • An alternate long and two short dashes line shows how the height position of the slide box 16 varies with the free length FL maintained constant.
  • the alternate long and two short dashes line is high on the right side because in order to allow the free length FL to be maintained constant even though the contact roller 8 is pushed up by the thickened package 4, the slide box 16 is elevated to offset the increment ⁇ D in winding diameter D.
  • the winding diameter D of the package 4 is varying from D2 to D3
  • the movement amount ⁇ G of the slide box 16 has a negative value, thus allowing the slide box 16 to lower.
  • Winding angle WA 12 degrees at the winding start and 10 degrees at the winding end.
  • a constant winding angle WA makes the wind number N equal to the critical wind number Nd toward the winding end.
  • the reduction in winding angle WA has no relation with the inhibition of possible bulging.

  • a trace of slip-down of the yarn 2 along the end surface of the package 4 was found.
  • the winder 1 that forms the package 4 is configured as follows.
  • the winder 1 includes the contact roller 8 configured to come into contact with the package 4 during formation of the package 4, the traverse device 7 located upstream side of the contact roller 8 in the traveling direction of the elastic yarn 2, the free length varying means 9 for enabling the free length FL of the elastic yarn 2 located between the contact roller 8 and the traverse device 7 (specifically, the traverse guide 31) to be varied during formation of the package 4, and the control section 80 configured to control the free length varying means 9 in such a manner that the free length FL is increased during winding start of the package 4 and then reduced toward winding end. This configuration allows possible bulging to be inhibited.
  • an increase and reduction in free length FL avoids varying the wind number N.
  • winding can be easily carried out with possible bulging inhibited and with the critical wind number Nd avoided.
  • Successful avoidance of the critical wind number Nd in turn allows avoidance of various problems: slip-down of the elastic yarn 2 along the end surface of the package 4 during traversing, vibration of the contact roller 8, and improper unwinding of the yarn from the package 4 during the subsequent step.
  • the above-described embodiment does not adopt the technique to increase and reduce the winding angle WA in order to inhibit possible bulging.
  • the technique to increase and reduce the winding angle WA may also be used.
  • the winding angle WA may be slightly reduced toward the winding end.
  • the free length FL is increased from FL1 to FL2 and reduced back to FL1.
  • the free length FL need not necessarily be reduced back to FL1.
  • the free length FL is preferably increased from FL1 to FL2 and then reduced back to FL1.
  • winding diameter D2, shown in Figure 8 of the package 4 corresponding to the turning point where the free length FL that has been increased so far starts to be reduced is preferably appropriately increased and reduced depending on yarn winding conditions.
  • the elastic yarn 2 is wound around the bobbin 3. If the elastic yarn 2 is used, a strong winding tightening force is exerted, resulting in significant bulging as described above. An attempt to deal with the significant bulging simply by increasing and reducing the winding angle WA results in the inevitable occurrence of ribbon winding. However, possible ribbon winding can be avoided by increasing and reducing the free length FL. Thus, the technique to inhibit possible bulging by increasing and reducing the free length FL is beneficial particularly when the elastic yarn 2 is used.
  • Figure 13 is a graph which is similar to Figure 8 and which shows how the free length FL and the winding angle WA are controlled based on the winding diameter D of the package 4 according to the second embodiment of the present invention.
  • the axis of abscissa indicates the winding diameter D of the package 4.
  • the axis of ordinate indicates the free length FL and the winding angle WA.
  • the winding angle WA increases from WA1 to WA2 consistently with the winding diameter D.
  • the winding angle WA reduces from WA2 to WA1 consistently with the winding diameter D so as to prevent the wind number N from equaling the critical wind number Nd.
  • Figure 14 is a flowchart which is similar to Figure 9 and which illustrates the second embodiment of the present invention.
  • Figure 13 like the Unexamined Japanese Patent Application Publication (Tokkai-Hei) No. 9-71367 , the present embodiment adopts the technique to increase and reduce the winding angle WA in order to inhibit possible bulging.
  • winding of the elastic yarn 2 is started with the free length FL set to FL1. Then, the control section 80 first calculates the winding diameter D of the current package 4.
  • control section 80 calculates the increment ⁇ D in the winding diameter D of the package 4 (S310).
  • the control section 80 then calculates the variation amount ⁇ FL of the free length (S330).
  • the control section 80 then calculates the movement amount ⁇ G of the slide box 16 (S340) .
  • the control section 80 then moves the slide box 16 up and down based on the movement amount ⁇ G calculated in S340 (S350).
  • the control section 80 then changes the current winding angle WA to the winding angle WA calculated as described in S360 (S370). Specifically, the control section 80 acquires the rotation speed of the contact roller 8 based on a sensing signal received from the rotation sensor 40. Then, taking into account the rotation speed of the contact roller 8, that is, the peripheral speed of the package 4, the control section 80 drivingly controls the traverse motor 28 so as to increase or reduce the rotation speed of the traverse cam 30 so that the current winding angle WA is set to the winding angle WA calculated as described in S360.
  • the control section 80 determines whether or not the winding diameter D of the package 4 calculated as described in S300 has reached the predetermined value Dmax (S380). Upon determining that the winding diameter D has not reached the predetermined value (S380: NO), the control section 80 shifts back to the processing in S300. On the other hand, upon determining that the winding diameter D has reached the predetermined value (S380: YES), the control section 80 rotates the turret plate 6, changes the bobbin 3, and starts a new winding operation.
  • the winder 1 is further configured as follows.
  • the winder 1 further includes a winding angle varying means for enabling the winding angle WA to be varied.
  • the control means 80 controls the winding angle varying means in such a manner that the winding angle WA is increased during the winding start of the package 4 and then reduced toward the winding end. In this manner, to allow possible bulging to be inhibited, both the free length FL and the winding angle WA are increased and reduced. This enables a reduction in the range of an increase and reduction in free length FL required to inhibit possible bulging. As a result, the free length varying means 9 can be made compact.
  • the technique to vary the winding width by varying the traverse width is compared with the technique to vary the winding width by varying the free length FL and the winding angle WA (that is, the traverse speed) with the traverse width maintained constant as is the case with the present embodiment, the latter technique allows the traverse width to remain constant, allowing even a yarn type such as elastic yarns to be smoothly wound. Moreover, the end surface is properly finished.
  • the turnaround point relating to the increase and reduction in free length FL and the turning point relating to the increase and reduction in the winding angle WA are reached when the winding diameter D of the package 4 reaches D2.
  • the turning point relating to the increase and reduction in free length FL may be out of alignment with the turning point relating to the increase and reduction in winding angle WA.
  • the winding angle WA is set to WA1 both at the start and end points of winding.
  • the winding angle WA at the start point may be different from that at the end point instead of being the same as that at the end point.
