Definitions

  • the present invention relates to a yarn winding method for a take-up winder and a take-up winder according to the preamble of claim 1 and 3, respectively.
  • a turret type take-up winder may use a traverse device to make a continuously supplied yarn traverse, and the turret is rotated to switch the two bobbin holders attached to the turret between a winding position and a standby position, and a contact roller contacts a bobbin at the winding position to wind the yarn supplied and traversed around the bobbin.
  • the present invention is provided in view of this problem in the conventional technique. Accordingly, the object of the present invention is to provide a winding method and take-up winder that varies the winding width in the axial direction of a bobbin in order to prevent saddle bag shape form being formed.
  • the winding method and the take-up winder according to the present invention configured as described above repeatedly causes a contact roller to contact and separate form a bobbin. This enables the free length to vary during yarn winding, and thus helps vary the winding width in the axial direction of the bobbin, thereby providing packages in which the edge shape of a yarn layer of package are prevented from becoming a saddle bag shape.
  • a take-up winder and a winding method for a take-up winder according to the present invention will be described below in detail based on specific examples shown in the drawings.
  • Figure 1 is a schematic front view showing a specific embodiment of a take-up winder according to the present invention. The figure shows a state at the end winding in which a yarn has been wound around a bobbin at a winding position in the take-up winder.
  • Figure 2 is a schematic side view showing the take-up winder as seen from the side.
  • the take-up winder U has a body frame 7 and an elevating box 1 that can ascend and descend, a rotatable turret plate 2 and a fixed frame 8 having an operation panel 9 at its front surface end are provided in the body frame 7.
  • a contact roller 3 and a traverse device 4 are supported in the elevating box 1.
  • the contact roller 3 applies pressure against the surface layer of yarn on a bobbin B at a winding position P1, and a driving source 10 comprising a motor M3, as shown in Figures 1 and 2, drives the-contact roller 3 so that the bobbin around which a yarn is being wound rotates counterclockwise.
  • a traverse device 4 has a traverse guide 5 so that the guide 5 engages a yarn Y to travel through the traversing range for performing traverse.
  • a rotational driving apparatus (not shown in the drawings) can rotate the turret plate 2 around a rotating shaft 6.
  • a first bobbin holder 11 and a second bobbin holder 12 are mounted on the turret plate 2 in such a way as to protrude therefrom.
  • a plurality of (in Figure 1, six) bobbins are installed on each of the bobbin holders 11 and 12.
  • One 11 of the bobbin holders 11, 12 is located at the winding position P1, while the other bobbin holder 12 is located at a standby position P2.
  • a driving source 13 comprising a motor M1 drives the first bobbin holder 11, while a driving source 14 comprising a motor M2 drives the second bobbin holder 12.
  • the yarn Y is wound around the bobbin B on the bobbin holder 11 located at the winding position P1.
  • the turret plate 2 rotates 180° to move the full bobbin FB at the winding position P1 to the standby position P2 while moving the empty bobbin EB prepared at the standby position P2 to the winding position P1.
  • a yarn transferring mechanism transfers the yarn from the full bobbin FB to the empty bobbin EB to provide continuous winding.
  • the plurality of (in the example shown in Figure 3, six) bobbins B are installed on each of the bobbin holders 11 and 12. During winding, one 11 of the bobbin holders 11, 12 is located at the winding position P1, while the other bobbin holder 12 is located at the standby position P2.
  • the yarn Y passes through the traverse guide 5 of the traverse device 4, around the contact roller 3, and onto the bobbin B at the winding position P1.
  • the contact controller 3 is configured to guide the traversing yam Y by the traverse guide 5 of the traverse device 4 and to repeatedly contact and separate from the bobbin during winding.
  • the yarn Y is guided to the bobbin B at the winding position at a distance of given free length L measured from the point at which the yarn Y leaves the contact roller 3 to the contact point of the winding yarn at the bobbin.
  • Figures 3 and 4 show a specific example of a configuration for varying the free length L in the winding method for the take-up winder according to the present invention.
  • Figure 3 shows a configuration in which the contact roller 3 is contacting the bobbin B ( Figure 3A), and in this configuration, the turret plate 2 supporting the bobbin B rotates ⁇ ° counterclockwise to mutually separate the bobbin B and the contact roller 3, thereby providing a long free length L (smaller winding width).
  • Figure 4 shows a configuration in which the contact roller 3 is contacting the bobbin B ( Figure 4A), and in this configuration, the elevating box 1 supporting the contact roller 3 ascends so as to mutually separate the bobbin B and the contact roller 3, thereby providing a long free length L (a smaller winding width).
  • An important characteristic of the present invention is that the rotations of the first and second bobbin holders 11 and 12 and the contact roller 3 must be controlled due to the configuration in which the contact roller 3 is separated from the bobbin B.
  • the drive motor 13 (M1) is provided for the first bobbin holder 11 holding the bobbin B
  • the second drive motor 14 (M2) is provided for the second bobbin holder 12
  • the third drive motor 10 (M3) is provided for the contact roller 3.
  • a contact roller rotation speed detection means 16 comprising a contact roller rotation speed detection sensor 15 provided for the contact roller 3 detects the rotation speed of the contact roller 3 to control the rotation speed of the motor 13 (M1) for the bobbin holder 11 at the winding position P1 on the basis of the detected value. If the bobbin holder 12 is at the winding position P1, the rotation speed of the motor 14 (M2) for the bobbin holder 12 is controlled.
  • the take-up winder U shown in Figure 1 comprises a contact/leave switching control means 17.
  • the contact/leave switching control means 17 outputs control signals to an elevation control means 18 for controlling the elevating box 1 as well as to a rotation control means 19 for controlling the rotation of the turret plate 2.
  • the contact/leave switching control means 17 also outputs control signals to a contact roller drive motor control means 20 for controlling the contact roller drive motor 10 (M3), a first bobbin holder drive motor control means 21 for controlling the first bobbin holder drive motor 13 (M1), and a second bobbin holder drive motor control means 22 for controlling the second bobbin holder drive motor 14 (M2).
  • a contact roller drive motor control means 20 for controlling the contact roller drive motor 10 (M3)
  • a first bobbin holder drive motor control means 21 for controlling the first bobbin holder drive motor 13 (M1)
  • a second bobbin holder drive motor control means 22 for controlling the second bobbin holder drive motor 14 (M2).
  • the contact/leave switching control means 17 supplies an instruction to the rotation control means 19 for the turret plate or the elevation control means 18 for the elevating box, and if the contact roller 3 separates from the bobbin B, the contact/leave switching control means 17 changes, via the bobbin holder drive motor control means, the control of the drive motor for the bobbin holder at the winding position P1.
  • the bobbin holder drive motor control means has a motor instruction value calculating means 23, a motor instruction value output means 24, and a motor instruction value input means 25, and while the bobbin B is contacting the contact roller 3, the motor instruction value calculating means 23 calculates a motor instruction value based on a detection signal from the contact roller rotation speed detection means 16, and the motor instruction value output means 24 outputs a control signal to the bobbin holder drive motor.
  • the motor instruction value calculating means 23 calculates a subsequent motor instruction value based on a detection signal (a motor instruction value) from the motor instruction value input means 25 provided when the bobbin B leaves the contact roller 3, and the motor instruction value output means 24 outputs a control signal to the bobbin holder drive motor.
  • the rotation speed (an instruction value for the bobbin holder drive motor) of the bobbin holder immediately before the bobbin B separates from the contact roller 3 is input, and after the bobbin B has left the contact roller 3, the rotation speed of the bobbin holder is reduced over time based on the input rotation speed.
  • Figure 5 is a schematic explanatory drawing for the winding method for a take-up winder according to the present invention.
  • Figure 5 is figure for explaning a principle how the winding width increases with decreasing free length and decreases with increasing free length, and also is a summary principle explanation figure which shows the state of the yarn path established when a yarn is wound at a winding angle ⁇ .
  • Figure 6 is a graph showing an example of the pattern of changes in free length based on the relationship between the free length and the winding diameter (winding duration).
  • the contact roller 3 is a driving roller and is driven by the driving source 10 comprising the motor M3, and is located between the traverse guide 5 and the bobbin B to guide the traversing yarn Y to the bobbin B. In this case, while that yarn is traveling, the contact roller 3 contacts and supports the yarn Y over a contact distance Lx.
  • the distance between the guide 5 and a contact start point CP 1 of a contact distance Lx on the contact roller 3 is defined as the first free length portion L o (fixed), and the distance between a contact end point CP 2 of the contact distance Lx on the contact roller 3 and a winding contact point WP of the bobbin B at the winding position is defined as the second free length portion (variable) which varies between free length L 1 and L 2 .
  • the winding width W1 is a winding width at the free length L 1 and the winding width W2 is a winding width at the free length L 2 .
  • the winding angle ⁇ is determined by the traversing speed of the traverse guide 5 of the traverse device 4 and the peripheral speed of the bobbin B, as shown in the vector diagram in Figure 5.
  • the yarn path established while the yarn Y is being wound around the bobbin B at the winding angle ⁇ is as shown in Figure 5.
  • the yarn Y follows a yarn path YA, and after the traverse guide 5 makes a turn, the yarn Y shifts to yarn path YB.
  • the winding width increases to W2 when the free length is short L 2 , and decreases to W1 when the free length is long L 1 .
  • the free length L becomes zero (0) and the winding width W is at a maximum.
  • the free length is switched between L 1 and 0 at specified times to allow the bobbin and the contact roller to contact and separate and thereby wind the yarn, as shown by pattern A in Figure 6.
  • the free length L is aperiodically varied between L 1 and 0 to allow the bobbin and the contact roller to contact and separate and thereby wind the yarn.
  • the per time during which the bobbin and the contact roller are mutually separated is preferably short, and within the overall winding time period, the total bobbin/contact roller separation time is preferably shorter than the total time during which they contact each other.
  • the traverse device is not limited to the illustrated cam traverse device, and may comprise a blade type traverse device.
  • the present invention can then be applied to, for example, the winding of elastic yarns etc..
  • the winding method for a take-up winder according to the present invention repeatedly causes a contact roller to contact and separate from a bobbin. This enables the free length to vary during yarn winding, and thus helps vary the winding width in the axial direction of the bobbin, thereby providing good yarn packages in which the edge shape of a yarn layer of a package are prevented from becoming a saddle bag shape. Therefore, this method is very effective in achieving the object of the present invention.
