Definitions

  • the present invention relate to a take-up winder according to the preamble of claim 1.
  • a take-up winder of this type is disclosed, in US-A-4 867 385.
  • This take-up winder has a yarn guide acting on the yarn portion between a yarn traversing guide and an empty bobbin. There is, therefore, a relatively long distance between the yarn guide and the full bobbin. Because the yarn is in contact with the empty bobbin the timing of the movement of the yarn may be delayed and makes the timing with which the yarn drops from the package of the full bobbin difficult.
  • US-A-4 210 293 discloses an apparatus for strand transferring that occurs during the exchange of two winding collets.
  • the apparatus comprises an ejector fork on the absturing side of the empty callet which shifts a strand on the full collet, and an finger acting on the strand between the empty and the full collets after the shifting has been terminated causing a slack of strand.
  • a slack of strand Unless skillful use is made of the slack at the moment it drops from the full collet to wind the required amount of strand on the empty collet directly after it drops from the layer of the full collet, transfer of this strand will fail.
  • a conventional take-up winder for an elastic yarn is disclosed for example in DE-A-44 14 180 A1 and has a turret with a turret plate and two bobbin holders mounted thereon to change the positions of the bobbin holders.
  • Such a type of take-up winder is also shown in Figure 2C and rotates and stops the turret 2 in such a way that an empty bobbin Be is located at a middle position M beyond the winding position K.
  • a yarn guide 7 that is a yarn-winding means is moved in such a way that yarn Y makes a single round of the empty bobbin Be, and a fully wound package P is suddenly stopped to loosen the yarn Y in order to adhere elastic yarn Ya to the surface of the empty bobbin Be.
  • the yarn Ya is wood around the surface of the empty bobbin Be and cut between the empty bobbin Be and the fully wound package P due to yarn tension caused by winding of the yarn Ya on the package P.
  • the subsequent elastic yarn Y is wound to fix the end of the elastic yarn Y adhered to the empty bobbin Be.
  • the empty bobbin Be is returned to the winding position K and a traversing device 4 is used to start regular winding, as shown in Figure 2D and Figure 2E.
  • Figure 4 shows the yarn guide 7 that is a yarn-winding means and the position of the yarn Y that is wound-around the empty bobbin Be and the fully wound package P.
  • the yarns, which have been contacted with each other may be separated causing yarn-transferring to fail if the amount of contact between the yarns is small, because the yarns, which have been extended during winding, are contracted following contact unless the yarn tension is reduced to contract the yarns in order to sufficiently contact them with each other.
  • This take-up winder suddenly stops the fully wound package to loosen the yarn in order to adhere the elastic yarn to the surface of the empty bobbin, so it requires a braking apparatus for making a sudden stop in such a way as to assist in the winding around the empty bobbin.
  • a straight winding occurs on the surface of the fully wound package wherein unwanted yarn generated during yarn-transferring is wound around one section.
  • the unwanted yarn in this case, the straight winding, must be removed due to its different physical properties resulting from conditions, such as yarn tension, that differ from those in normal winding.
  • the elastic yarn is thin and very sticky, the end of the yarn (the winding end part of the elastic yam) can not be found easily through the use of suction.
  • the straight winding has been removed by picking the corresponding yarn up with nails and pulling it out from the package. In this case, the nails may damage the surface of the package.
  • This invention is provided in view of the problems with the prior art, and its object is to provide a take-up winder for elastic yarn that can reliably transfer the yarn using a simple structure and that can easily remove the winding end part of the yarn from a package.
  • the invention includes a yarn-transferring means that releases yarn wound around a package from a winding width and transfers the yarn to an empty bobbin using a decrease in the yarn tension caused by the winding of the yarn around the bobbin end of a fully wound package that is winding at a different peripheral speed.
  • the invention transfers the yarn fed from the surface of the package that is at a high rotational speed, to the bobbin end that is at a low rotational speed to reduce yarn tension in order to loosen the elastic yarn, thereby assisting the winding of the yarn around the empty bobbin.
  • the yarn-transferring means is also used as a yarn-winding means for winding elastic yarn around the empty bobbin.
  • the yarn-transferring means not only removes the yarn from the winding width of the package but also acts as the yarn-winding means to directly wind the removed yarn around the empty bobbin.
  • the time after the yarn-transferring means has released the yarn fed to the fully wound package from the winding width until this yarn-transferring means contacts the yarn on the downstream side of the empty bobbin with the yarn an the upstream side thereof is set at the amount of time required for a bunch winding to be formed at the end of the fully wound package.
  • the take-up winder 5 comprises an elevating frame 1 that can be elevated from and lowered into a machine frame 8, and a rotatable turret 2 that is a position-changing means for the bobbin holders.
  • a touch roller 3 and a traversing device 4 are each supported by the elevating frame 1, and the touch roller 3 constantly contacts the yarn layer of a bobbin at a winding position, which is described below, to rotationally drive the bobbin counterclockwise.
  • the traversing device 4 includes a traversing guide 6 that engages yarn Y and moves back and forth within a traversing range in order to traverse the yarn Y.
  • the yarn Y is continuously fed from a spinning machine (not shown in the drawing) at a predetermined travelling speed.
  • the turret 2 is driven around a rotating shaft 14 by a driving source such as a induction motor (not shown in the drawing).
  • a bobbin is installed in each of two bobbin holders 15, 16, and one of the bobbin holders 15 is located at a winding position K while the other holder 16 is located at a standby position L.
  • the bobbin on which a yarn layer is formed that is, the bobbin with a package P, is referred to as Bf and an empty bobbin is referred to as Be.
  • a yarn guide 7 that is a yarn-winding means consists of an oscillating arm 17 borne by a shaft to the lower part of the machine frame 8 and a guide bar 18 attached to the tip of the oscillating arm 17.
  • the oscillating arm 17 is provided on the side of the tips of the bobbin holders 15, 16 and extends the guide bar 18 from that side to the side of the root of the bobbin holders 15, 16 in a cantilever manner.
  • a rotating shaft 19 of the oscillating arm 17 is provided in such a position that when the empty bobbin Be located at a yarn-transferring position is located at a middle position M shown in Figure 2C, the oscillating arm 17 can be rotated to cause the guide bar 18 to wind the yarn Y around the empty bobbin Be.
  • the yarn-transferring position is set, at the middle position M between the winding position K and the standby position L in order to simplify the structure of the take-up winder by increasing the winding angle of the yarn Y relative to the empty bobbin Be to one-third or more of the total circumference to reduce the amount of rotation of the yarn guide 7, and allowing the yarn guide 7 to be simply rotated away from the rotational traces of the bobbin holders 15, 16.
  • the oscillating arm 17 is oscillated around the shaft 19 by a driving means such as a rotary actuator (not shown in the drawings), and the yarn guide 7 is moved between the standby position (in fact, at the standby position, the guide bar 18 is arranged so as to come off from the rotation locus of the fully wound package P) indicated by the solid line in Figure 1 and the operating position indicated by the chain double-dashed line.
  • a driving means such as a rotary actuator (not shown in the drawings)
  • the guide bar 18 is attached to the tip of the oscillating arm 17 and includes the guide groove 9 that is entered by the yarn Y as shown in Figure 3.
  • the guide groove 9 consists of a curved portion 10 that guides the yarn Y along the curve and a notch portion 11 for restricting the yarn Y that is guided by the curved portion 10.
  • the part of the groove in which the curved portion 10 and the notch portion 11 are combined together has a somewhat larger width than the yarn so as to reliably contact the yarn Ya with the yarn Yb.
  • the curved portion 10 and the notch portion 11 are combined together at a position offset from the winding width (traversing range) of the package P.
  • the yarn guide 7 acts not only as a winding-start yarn-winding means for winding the winding start part of the yarn Y around the end of the empty bobbin Be through the guide groove 9, but also as a yarn-transferring means for transferring the yarn Y from the surface of the yarn layer of the package P to the end of the bobbin Bf. This configuration reduces the number of required parts and simplifies the structure of the take-up winder, and thus simplifies its control.
  • the yarn Ya which has been transferred from the layer of the fully wound package P to the end of the bobbin Bf through the guide groove 9, is wound at the lower speed of the bobbin Bf instead of the higher speed of the yarn layer of the fully wound package P, thereby substantially and instantaneously reducing the yarn tension.
  • the instantaneous decrease in yarn tension is used as an alternative to reliably and sufficiently contact the yarns Ya and Yb with each other in order to assist in the winding of the yarn around the empty bobbin Be.
  • the yarn Ya transferred from the fully wound package P to the end of the bobbin Bf has its tension reduced not only instantaneously but also continuously until yarn-transferring has been completed, followed by the catting of the yam.
  • the take-up winder controls the rotation of the bobbin holders to make the peripheral speed of the fully wound package P equal to that of the empty bobbin Be, thereby increasing the peripheral speed of the empty bobbin Be to higher than that of the bobbin Bf of the fully wound package P.
  • the empty bobbin Be provides the same function as a feed roller to reduce the tension of the yarn Ya located on the downstream side of the empty bobbin Be.
  • the yarn can be reliably transferred some time after it has been transferred from the fully wound package P to the end of the bobbin Bf. That is, the yarn can be transferred by contacting the yarns Ya and Yb with each other after unwanted yarn resulting from yarn-transferring is reliably wound around one section of the end of the bobbin Bf many times to form a bunch winding 12.
  • the yarn In the straight winding, the yarn is wound around one section of the package surface, whereas in the bunch winding 12, the winding end part of the yarn wound around the package P is located at the end of the bobbin Bf, thereby allowing the end of the yarn to be located and picked up easily and preventing the package surface from being damaged when the end is picked up by nails.
  • This configuration also allows unwanted yarn resulting from yarn-transferring to be removed easily without damaging the package P.
  • a controller (not shown in the drawings) controls the rotational timing and speed of the driving means for the yarn guide 7, and of the drive source for the turret 2.
  • the yarn Y continues to be traversed when the positions of the bobbin holders are changed.
  • the empty bobbin Be reaches the middle position M and the yarn guide 7 is rotated counterclockwise, the yarn Ya, which is being traversed, is captured in the guide groove 9.
  • the yarn guide 7 is further rotated to move the yarn Ya from the surface of the fully wound package P to the end of the bobbin Bf along the curved portion 10, while capturing and guiding the yarn Yb on the upstream side.
  • the yarn guide 7 is rotated until the yarn Ya contacts that yarn Yb.
  • the yarn tension is substantially reduced due to the difference in peripheral speed between the fully wound package P and the bobbin Bf.
  • the decrease in yarn tension allows the yarn Y to be loosened with no need to suddenly stop the bobbin holder 15 at the side of the fully wound package P, causing the yarns Ya and Yb to be reliably and sufficiently contacted with each other within the guide groove 9.
  • the yarn Ya is reliably entwined with the yarn Yb and is then extended and cut, and the yarn Y (yam at the winding start part) is wound around the end of the empty bobbin Be to form a bunch winding of the winding start at the end of the empty bobbin Be.
  • the yarn guide 7 is returned to its standby position and the turret 2 is rotated clockwise to move the empty bobbin Be to the winding position K as shown in Figure 2E in order to contact it with the touch roller 3 for regular winding.
  • the rotation of the turret 2 may be stopped at the position shown in Figure 2D, and the package may be moved to the position shown in Figure 2E after its diameter has reached a specified value.
  • this winding method using the decrease in tension during yarn-transferring, the yarn guide 7 moves the yarn Y from the fully wound package P to the end of the bobbin Bf through the guide groove 9 while catching the yarn Ya on the bobbin Bf, and is then rotated until the Ya contacts the yarn Yb. That is, this method loosens and reliably winds the yarn Ya around the empty bobbin Be using only the decrease in tension occurring when the yarn Y is transferred from the surface of the package P to the end of the bobbin Bf.
  • this method does not always form a sufficient and required amount of bunch winding 12 (bunch winding of the winding end part) at the end of the bobbin Bf located at the side of the package P.
  • a method for reliably forming a bunch winding 12 is described below. This method is also effective in preventing the end of the yarn from being released during transport.
  • This method is the same as the above method until the yarn guide 7 is rotated counterclockwise after the empty bobbin Be has reached the middle position M, so the description of this part is omitted.
  • the yarn guide 7 When the empty bobbin Be reaches the middle position M, the yarn guide 7 is rotated counterclockwise. The yarn guide 7 moves the yarn Ya from the surface of the fully wound package P to the end of the bobbin Bf through the guide groove 9 while capturing and guiding the yarn Yb on the upstream side, and is stopped rotating immediately before the yarn Ya contacts the yarn Yb. When the rotation of the yarn guide 7 is stopped, the yarn Ya (yarn at the winding end part) continues to be wound at one position on the bobbin Bf offset from the winding range, in order to form a bunch winding 12.
  • the yarn guide 7 is rotated until the yarn Ya contacts the yarn Yb. Since the peripheral speed of the bobbin Bf for the package is lower than the travelling speed of the yarn, the peripheral speed of the empty bobbin Be is almost equal to this travelling speed, the rotational speed of the bobbin Bf differs from that of the empty bobbin Be, the tension of the yarn Ya remains at the reduced value, and the yarn Ya is loosened without the need to suddenly stop the bobbin holder 15 for the fully wound package P.
  • the yarns Ya and Yb which are both restricted within the guide groove 9, are reliably and sufficiently contacted with each other, and the yarn Ya is reliably entwined with the yarn Yb and is then extended and cut, causing the yarn Y to be wound around the empty bobbin Be.
  • the empty bobbin Be is placed at the winding position K as in the above method.
  • the yarn guide 7 also operates as a winding-end yarn-winding means for winding the winding end part of the yarn around the end of the fully wound bobbin.
  • This invention may be embodied as follows: Although the present embodiment stops the rotation of the yarn guide 7 to rel iably form the bunch winding 12, the speed at which the yarn guide 7 is rotated may be reduced to delay contact between the yarns Ya and Yb and the subsequent cutting of the yarn Ya, thereby allowing the bunch winding 12 to be reliably formed.
  • the invention uses the difference in peripheral speed between the package and the bobbin of the ful ly wound package, so it does not require a large braking apparatus for sadden stopping of the fully wound package.
  • a small apparatus that can eventually stop the inertial rotation of the fully wound package may be used to provide a take-up winder that can reliably transfer the yarn using a simple structure.
  • the yarn-transferring means releases the yarn from the winding width of the package and this yarn transferring means directly winds the released yarn around the empty bobbin, thereby reducing the number of required parts, simplifying the structure of the take-up winder, and thus simplifying its control.
  • the invention winds the winding end part of the elastic yarn around the end of the bobbin instead of the yarn layer of the full bobbin, thereby enabling the winding end of the yarn to be located and picked up easily.
  • unwanted yarn resulting from yarn-transferring can be reliably wound around the bobbin and removed without damaging the package. Consequently, this invention provides a take-up winder for elastic yarn that can remove unwanted yarn resulting from yarn-transferring without damaging the package.
