In the above, the structure of the thread winding device 1 was demonstrated. Next, the arrangement relationship of the belt-type traverse apparatus 5 which adjoins mutually is demonstrated, referring FIG.

That is, as shown in FIG. 2, in this embodiment, the belt-type traverse apparatus 5 which adjoins mutually is arrange | positioned so that they mutually overlap. Specifically, the belt-type traverse apparatus 5 which adjoins mutually is made to overlap by inclining the rail 19 with respect to the longitudinal direction of the bobbin holder 3. In addition, since the rail 19 corresponds to the trajectory of the reciprocating motion of the seal guide 4, it can be said as follows. That is, the belt-type traverse apparatus 5 which adjoins mutually overlaps by making the track | route of the reciprocation motion of the seal guide 4 incline with respect to the longitudinal direction of the bobbin holder 3.

As shown in FIG. 4, the shallow groove 2T for rod winding for forming what is called rod winding (it is also called tail end winding) is formed in the front end side edge part of the winding bobbin 2 of this embodiment. . The package Q, which is roughly represented by a dashed two-dot chain line, is formed between the shallow groove 2T for winding the rod and the other end side of the winding bobbin 2. In addition, the belt-type traverse device 5 can guide the thread Y in a wide range including the shallow groove 2T for winding the rod in addition to the package length of the package Q. It is designed to be wide enough to be used.

Next, the structure of the winding control part 60 is demonstrated, referring FIG. 5 is a control block diagram of the thread winding device.

That is, the winding control unit 60 includes a CPU (Central Processing Unit) which is an arithmetic processing unit, a control program executed by the CPU and a ROM (Read Only Memory) storing data used for the control program, and data at the time of program execution. RAM (Random Access Memory) for temporarily storing the data. Then, the control program stored in the ROM is input to the CPU and executed on the CPU, so that the control program uses hardware such as the CPU to traverse the control unit (Nos. 1 to 4) 61, the origin change unit 62, and the bobbin holder control unit ( 63). The number assigned to each traverse control part is assigned from the front end side in FIG. In addition, the winding control unit 60 is connected with a drive motor (Nos. 1 to 4) 17, a keyboard 13, a bobbin holder motor 14, and a turret motor 27. The numbers assigned to the respective drive motors are also assigned from the front end side in FIG. 1 similarly to the traverse control unit.

Each traverse control unit (Nos. 1 to 4) 61 has a control pattern storage unit 64 and an origin storage unit 65, and the control pattern and the origin storage unit 65 stored in the control pattern storage unit 64. The drive motors (No. 1 to 4) 17 of each belt-type traverse device 5 are controlled based on the origin stored in the. Specifically, each of the traverse control units (No. 1 to 4) 61 has a respective drive motor (No. 1 to 4) 17 is configured to control.

The control pattern of the drive motor 17 is stored in the control pattern storage unit 64. In this embodiment, the said control pattern is created so that the package Q formed on the winding bobbin 2 may become a taper end package shown by the dashed-dotted line in FIG. do. In other words, the reciprocating width of the reciprocating motion of the seal guide 4 is gradually narrowed from the start of winding to the end of winding. By changing the interval of inversion in this way, the belt type traverse apparatus 5 which concerns on this embodiment is comprised so that the reciprocation width of the reciprocation motion of the seal guide 4 can be changed freely. An example of this control pattern is shown in FIG. 6 is a diagram illustrating a control pattern of the traverse device. In FIG. 6, the vertical axis means traverse speed Vt, and the horizontal axis means time t. In addition, in FIG. 4, the traverse speed Vt when the seal guide 4 advances to the front end side is made into + in FIG. As shown in FIG. 6, the control pattern which concerns on this embodiment is specifically created so that the movement pattern in the vicinity of the traverse both ends of the seal guide 4 may differ. More specifically, in Fig. 4, the traverse speed Vt of the seal guide 4 immediately after the seal guide 4 reaches the right end of the reciprocating range of the reciprocating motion and is reversed is set slightly higher. That is, only the right end is configured to perform feed forward control in order to eliminate the stay of thread Y at the time of reversal. In addition, the control pattern shown in FIG. 6 was created so that a ridge angle might be 0.5 degree | times. It is preferable to make this ridge angle 1 degree or less. As is well known, the adjustment of the ridge angle may be performed by increasing or decreasing the amplitude of the traverse speed Vt.

The origin storage unit 65 stores the origin as a reference for the reciprocation of the seal guide 4 of the belt traverse device 5. Here, "origin" means the position of the center point of the reciprocating motion of the thread guide 4 of the belt type traverse apparatus 5 in this embodiment.

The origin change unit 62 is stored in the origin storage unit 65 of each traverse control unit (No. 1 to 4) 61 based on the amount of expansion and contraction of the winding bobbin 2 input through the keyboard 13. Change the origin. 7 is a partially enlarged view of the tip portion of the bobbin holder. Specifically, the amount of expansion and contraction is the amount of expansion and contraction in the direction of the bobbin length of the entire plurality of winding bobbins 2 and is wound on the front end side of the plurality of winding bobbins 2 filled and arranged on one side on the bobbin holder 3. The position of the front end side end surface E of the bobbin 2 can be acquired by reading on the scale S of FIG. 7 engraved on the bobbin holder 3. For example, as shown in FIG. 7, when the position of the front end side end surface E of the said winding bobbin 2 is "-2.8 mm" on the scale S, the said amount of expansion and contraction will become "-2.8 mm". Then, the origin changing unit 62 divides the amount of expansion and contraction ΔL by 8 and multiplies 7 by 7/8 ΔL to the origin stored in the origin storage unit 65 of the traverse control unit (No. 1) 61. Add. Similarly, the origin change unit 62 transmits 5 / 8ΔL to the origin stored in the origin storage unit 65 of the traverse control unit (No. 2) 61 and 3 / 8ΔL to the traverse control unit (No. 3) 61. 1 / 8ΔL is added to the origin stored in the origin storage unit 65 of the traverse control unit (No. 4) 61, respectively. In addition, the operation of the origin change unit 62 is that the bobbin length is changed by the humidity of the environment in which the winding bobbin 2 is used for paper making, and the change in the bobbin length is between all the winding bobbins 2. It is assumed that they occur evenly in the.

The bobbin holder controller 63 controls the rotation of the bobbin holder motor 14.

In addition, the winding control unit 60 includes a turret control unit for controlling the rotation of the turret motor 27.

Next, the operation of the present embodiment will be described. The operator first fills the empty take-up bobbin 2 in the direction of the turret half 10 for each of the pair of bobbin holders 3.

Then, the operator operates the keyboard 13 or the like to operate the spin take-up machine 7, and also reads the amount of stretch and inputs it to the take-up control unit 60. Then, the origin change unit 62 changes the origin stored in the origin storage unit 65 of each traverse control unit (Nos. 1 to 4) 61 as described above. By changing this origin, the reciprocating range of the reciprocating motion of each thread guide 4 is slightly out of the longitudinal direction of the bobbin holder 3.

The four yarns Y discharged from the radiating part are sucked and held by the suction gun (not shown), and the bobbin holder controller 63 drives the bobbin holder motor 14 to drive the winding bobbin 2. Rotate to the desired speed. Each thread Y which is sucked and held by the suction gun is guided to the shallow grooves 2T for rod winding of each winding bobbin 2. As a result, each thread Y is strongly gripped by the shallow groove 2T for winding the bobbin 2 of each winding bobbin 2, and the suction holding state by the suction gun is released, so that each thread Y is wound. It climbs from the shallow groove 2T to the outer peripheral surface of the winding bobbin 2, and moves while spiraling toward the center of the bobbin length of the winding bobbin 2.

Next, each traverse control unit (Nos. 1 to 4) 61 is based on the control pattern stored in the control pattern storage unit 64 and the origin stored in the origin storage unit 65. .1 ~ 4) (17). As a result, each thread Y is captured by each thread guide 4 and begins to traverse so as to be cross-wound (see also FIG. 3), and on each winding bobbin 2 shown in FIG. 4. The tapered end package Q as described above is formed by cross winding (winding process).

When the package Q is completely wound up, the turret control unit drives the turret motor 27 to rotate the turret half 10 counterclockwise by 180 degrees, and each traverse control unit (Nos. 1 to 4) (61). ) Moves the seal guide 4 to a position opposite the shallow groove 2T for rod winding. Then, each thread Y is strongly held in the same manner as above in the shallow grooves 2T for rod winding of the empty winding bobbin 2. Subsequently, each of the drive motors (No. 1 to 4) 61 is based on the control pattern stored in the control pattern storage unit 64 and the origin stored in the origin storage unit 65 again. .1 ~ 4) (17). Thereby, on each winding bobbin 2, the capture | acquisition of thread | dye Y by the thread guide 4 is not interrupted, and the taper end type package Q as shown in FIG. 4 is again formed by cross winding. do.

Next, the test for confirming the technical effect by making ridge angle 1 degree or less as mentioned above is demonstrated. Numerical limitations on the ridges are reasonably supported by the following confirmation tests. In the following confirmation test, the relationship between the finish state of the end surface shape of the taper end package Q, and a ridge angle was investigated using the said thread winding device 1.

First, the evaluation method of each confirmation test is demonstrated. It is a figure which shows the index of the evaluation in the test for confirming the technical effect by the special setting of a ridge angle. 8 (a) shows the appearance of the tapered end package according to the embodiment, and FIG. 8 (b) shows the appearance of the tapered end package according to the comparative example. That is, when the end face shape of the package wound up is observed, and this end face shape shows a linear beautiful silhouette as shown in FIG. 8 (a), the confirmation test is evaluated as "(good)", On the other hand, when this end surface shape is made into the unevenness | corrugation only by seeing at first glance, as shown in FIG. However, when it cannot be determined whether to evaluate by "(circle)" or "x", it shall evaluate by "(triangle | delta)".

The test conditions common to each confirmation test are as follows.

Thread (Y): Monofilament (20 dtex) of approximately circular cross section

ㆍ Diameter of winding bobbin: φ110 mm

ㆍ Diameter of tapered end package Q: φ200 mm

Winding width of the tapered end package Q: Winding start = 270 mm to winding end = 114 mm Taper angle A of the cross section of the tapered end package Q (see Fig. 8): 30 [deg.] (θ) (see also in conjunction with FIG. 8): as shown in Table 1 below. In addition, the traverse speed Vt set slightly higher immediately after the inversion shown in FIG. 6 is not considered.

The free length ΔF (see FIG. 4), which is the travel distance of the thread Y between the thread guide 4 and the contact roller 11, can be set between 25 and 45 mm, and in this test, 25 It set to mm.

Next, the test results of each confirmation test are shown in Table 1 below.

Ridge angle θdeg. Evaluation of the finish of the end face shape 6.0 × 2.0 × 1.2 △ 1.0 ○ 0.5 ○ 0.2 ○

According to the said Table 1, when the ridge angle is 1 degree or less, it turns out that the finish of an end surface shape is favorable. In addition, the finishing state of the end surface shape obtained by making a ridge angle 1 degree or less was not obtained when ridge angle was 1.2 degrees or more.

Hereinafter, the present inventor introduces the process which found the special numerical limitation of the said ridge angle (theta) [deg.].

In the beginning, generally, when multifilament is wound by cross-winding and a cheese package is formed, it is common technical knowledge to set the ridge angle (theta) [deg.] To 4-8. In this case, if the ridge angle [theta] [deg.] Is less than 4, the cross section of the cheese package will bulge in the longitudinal direction of the package, and if the ridge angle [theta] [deg.] Is more than 8, the cheese package will be This is because the end of the shrunk shrinks.

This time, the taper end package was adopted from the viewpoint that the end face of the monofilament was easily distracted in cross winding the monofilament. However, it was originally bound by the above technical common sense and attempted to adopt 4 as the ridge angle [theta] [deg.]. Was doing. However, at this ridge angle [theta] [deg.], The appearance of the end face shape of the tapered end package is bad as seen at first glance, as shown in Fig. 8B.

Here, the inventor of the present invention noticed that the setting of the ridge angle θ [deg.] Was initially targeted to the cheese package, and thus the assignment of the ridge angle θ [deg.] Was largely allocated. When the ridge angle [theta] [deg.] which is remarkably small compared to [deg.] is adopted, that is, the ridge angle [theta] [deg.] of 1 degree or less is adopted, the end face shape as shown in Fig. 8 (a) is good. It was found that a finish was obtained.

And the inventor of the present application performed the above-mentioned confirmation test, and performed well-known winding density calculation in order to reproduce the meaning of numerical limitation on a calculation. 9 is a calculation result of the calculation for confirming the technical effect by the special setting of the ridge angle. That is, FIG. 9 (a) shows the distribution of the winding density when the ridge angle [theta] [deg.] Is 0.5, and FIG. 9 (b) shows the winding when the ridge angle [theta] [deg.] Is 6.0. The distribution of density is shown. 9 (a) and 9 (b), the horizontal axis represents the winding width position [mm], that is, the position in the longitudinal direction of the package, and the winding width position of the end of the longitudinal direction at the start of winding the package. Mm. 9 (a) and 9 (b) each show the winding density [%]. The winding density [%] means the occupied cross-sectional area of yarns occupying the space, and the winding density [%] in the longitudinal center of the package is 100. According to Figs. 9 (a) and 9 (b), when the ridge angle [theta] [deg.] Is set to 0.5, the ridge angle θ with respect to uniform winding density [%] from the center of the package in the longitudinal direction to the longitudinal end thereof is shown. When 6.0 [deg.] was set to 6.0, it was found that the winding density [%] at the longitudinal end was extremely high compared with the longitudinal center of the package. As the ridge angle [theta] [deg.] Increases, as shown in FIG. 10, the followability of thread to the movement of the thread guide at the time of inversion of a thread guide worsens, As a result, the length of a package The direction end is considered to be because thread thread tries to stay for a long time compared with the longitudinal center of a package. In addition, the calculation data shown with the broken line in FIG. 9 (b) is data corresponding to the movement of the yarn before the yarn thread inversion (not at the time of inversion of the real guide) in FIG. 10 (b). The calculation data shown by the solid line is the data corresponding to the movement of the thread after the thread inversion in Fig. 10B. In other words, the thread thread satisfactorily follows the movement of the thread guide in the stage before the thread thread inversion, but it is difficult to follow the movement of the thread guide in the step after the thread thread inversion. This is shown as other calculation data as shown by the solid line and the broken line on the graph of FIG.9 (b).

Therefore, it becomes possible to wind up the monofilament which an end surface is easy to be distracted by cross winding.

The thread winding device 1 is further configured as follows. That is, each of the traverse control units (No. 1 to 4) 61 controlling the belt-type traverse device 5 so that the reciprocating width of the reciprocating motion of the seal guide 4 gradually narrows from the start of winding to the end of winding. Is installed. The traverse control units (No. 1 to 4) 61 control the belt-type traverse device 5 so that the ridge angle is 1 degree or less.

In addition, the tapered end package Q formed using the said spin winder 7 is a thing in which a monofilament was wound directly by cross winding.

Incidentally, yarn winding is performed in the following manner. That is, the traverse width of each thread Y is gradually narrowed from the start of the winding to the end of the winding in winding up the winding bobbin 2 while traversing the plurality of threads Y by cross winding. According to the above method, it becomes possible to wind up the monofilament which the end surface is easy to be distorted as what is called a tapered end package Q by cross winding.

The thread winding is further performed in the following manner. That is, the ridge angle θ is 1 degree or less. According to the said special ridge angle (theta), the shape of the end surface of the tapered end package Q becomes favorable.

In addition, spinning winding is performed by the following method. That is, it comprises a release step of releasing the monofilament, and a winding step of winding the released monofilament directly by the thread winding method. According to the above method, the tapered end package Q can be produced by winding up the monofilament which an end surface is easy to be distracted by cross winding.

The tapered end package Q formed by the said spin winding method winds and forms the monofilament directly by cross winding.

As mentioned above, although preferred embodiment of this invention was described, the said embodiment can be changed and implemented as follows.

That is, for example, in the above-described embodiment, the belt-type traverse device 5 is adopted as the traverse device 5, but if the reciprocation width of the reciprocating motion of the seal guide 4 can be changed, other traverse devices (5) For example, a female traverse apparatus or a cam type traverse apparatus may be employed. A female traverse apparatus is a traverse apparatus which pivotally reciprocates the arm member in which the thread guide is formed in the front end by the drive motor comprised by the voice coil motor. Moreover, a cam type traverse apparatus is a traverse apparatus provided with a traverse cam, the traverse guide provided so that a slide movement is possible in engagement with the traverse groove formed in the circumferential surface, and the traverse guide drive motor which rotates the said traverse cam.

In the above embodiment, the case where the monofilament is mainly wound is described. Alternatively, the tapered end package may be formed by winding the multifilament by cross winding.

In addition, in this specification, a taper end package means only that taper angle A is 45 degrees or less in FIG.
