Description of the invention (1) [Technical Field] The present invention relates to a winding device for a line and a method for manufacturing a line package, which can wind the line at a high speed. [Technical background] Up to now, the production process of synthetic fibers has been speeded up for the purpose of improving productivity and improving thread quality. Generally, it has become a manufacturing process of synthetic fibers whose line winding speed is 5,000 m / min or more. On the one hand, attempts have been made to put into practice a coiling device that can coil lines at a speed of 7,000 m / min or more. Furthermore, in this practical application, if the length of the bobbin holder of the line winding device can be realized, it is possible to reduce the operating cost of the synthetic fiber manufacturing process and improve productivity. Under these circumstances, we have developed a long bobbin holder that can be used at high speeds. The biggest problem developed here is how to suppress the vibration of the long-sized bobbin holder during high-speed rotation. A bobbin holder for a high-speed winding device for a line, for example, disclosed in Japanese Patent Publication No. 275 1 5 5 1, Shi Jie 02-0 1 5 8 8 8, or JP 8- 1 75 7 5 Bulletin 3. The structure of these bobbin holders is shown in Figure 13. As shown in FIG. 13, the bobbin holder 30 is formed by a cylindrical member 31 that supports four cylindrical bobbin sections 100 freely and detachably. The cylindrical member 31 has a hub 36 in its inside. One end of the mandrel 3 4 (the left end) is attached to the hub 36. The end face of the other end (right end) of the mandrel 34 is located opposite to the end face of the end of the motor shaft 39 of the motor 38 (left end 565525 5. Part (2) of the description of the invention) . A tubular support body 3 3 is attached to the motor case 37. The front end on the side opposite to the tubular support body 3 3 is located inside the cylindrical member 31. The position of the mandrel 34 is inside the tubular support 3 3. A bearing 35, which rotatably supports the mandrel 34, is mounted inside the tubular support body 33. The right end portion of the mandrel 34 and the left end portion of the motor shaft 39 are coupled to the mandrel 34 as a flexible coupling 40 for transmitting the rotational force of the motor shaft 39 to the torque device. The prepared bobbin 100 is a bobbin holding mechanism 32 which can be detachably mounted on the bobbin holder 31 of the bobbin holder 30. Compressed air supply holes 3 9 a and 3 4 a for operating the bobbin holding mechanism 32 are provided on the motor shaft 39 and the mandrel 34. The detailed structure of the flexible coupling 40 that transmits the rotational force of the motor shaft 39 to the mandrel 34 as a torque transmission device is shown in Fig. 14. The rotation axis of the mandrel 34 and the rotation axis of the motor shaft 39 in FIG. 14 are substantially the same, and the right end of the mandrel 34 and the left end of the motor shaft 39 face each other and are located in a separated position. . The right shaft end of the mandrel 34 and the left shaft end of the motor shaft 39 are connected by a flexible coupling 40 so as to transmit the rotational force of the motor shaft 39 to the mandrel 34. A seal member 41 is provided between the right shaft end portion of the mandrel 34 and the left shaft end portion of the motor 39. In addition, according to the sealing member 41, leakage of the compressed air supply holes 39a, 34a in the partition of the compressed air is prevented. The previous connecting portion of the right end of the mandrel 3 4 and the left end of the motor shaft 39 is a transmission device and a compression space supply device that only have a rotating torque, but does not have an active support mandrel. 3 4 of the deflected structure. 565525 V. Description of the invention (3) In Japanese Patent Application Laid-Open No. 2-225268, Patent No. 275 1 5 51, or Japanese Patent Application No. 8-1 75753, it is described that the shape of the cylindrical member of the bobbin holder is improved. Or material, you can speed up the winding speed of the line. However, the length of the bobbin in the axial direction of the bobbin holder (the total extension of the bobbin), using a bobbin holder with a length of more than 1,200 mm, at a winding speed of more than 6000 m / min. When taking lines, a winding device suitable for the lines cannot be realized only by improving the shape or material of the cylindrical member of the bobbin holder. The inventors have seen that the previous bobbin holder is a vibration that oscillates at the front end of the motor shaft side of the mandrel at high speeds, and thus oscillates. Therefore, it is impossible to achieve a line winding speed of 6000 m / min or more Make the required high-speed rotation of the mandrel. Measures taken to improve the natural vibration number of the cylindrical member of the bobbin holder from the previous measures are taken: 'Because the vibration system of the mandrel is not solely generated by the vibration of the cylindrical member', when it becomes a high-speed rotation above a certain level, it is determined The natural vibration number of the structure formed by the bobbin holder and the mandrel has not been improved.

Description of the invention (15) The fitting shape of the moment is sufficient. In the above-mentioned embodiment, it has been described that the elastic bodies 20 and 22 exist in the joint portion of the mandrel 8 and the motor shaft 12. However, the deflected state (displacement of the deflection direction) of the connection portion between the mandrel 8 and the motor shaft 12 is made to be approximately the same state. Depending on the rigidity of the motor shaft 12 as long as the mandrel 8 can be restricted, It is a form in which the elastic bodies 20 and 22 do not exist. That is, the mandrel 8 and the motor shaft 12 have sufficient concentric accuracy, and the centering displacement does not need to have an elastic body in the connecting portion unless problems such as vibration or abrasion of the connecting portion occur. The cross-sectional shape of the first shaft end portion 8 c of the mandrel 8 of the fitting portion may be non-circular in the axial direction of the entire fitting portion. In this case, the cross-sectional shape of the hole 1 2c provided in the first shaft end portion 12g of the motor shaft 12 fitted to the first shaft end portion 8c of the spindle 8 is “corresponding to the first shaft end portion 8c”. The cross-sectional shape of the uniaxial end portion 8c is preferable. Next, the ideal ranges of the respective shaft diameters of the connecting portion of the mandrel 8 and the motor shaft 12 and the axial length of the fitting portion will be described. In FIG. 9, among the bearings 1 1 of the mandrel 8 arranged in the tubular support 9, the mandrel on the mandrel 8 side (the bearing 1 1 on the side of the first shaft end portion 8 c of the mandrel 8) The shaft diameter of 8 is D 1, the shaft diameter of the mandrel 8 and the embedded portion of the mandrel 8 and the motor shaft 1 2 (the elastic bodies 20 and 22 are mounted) is d, the bearing 15 of the motor shaft 12, and the motor 12 When the shaft diameter of the motor shaft 12 of the side bearing 15 (the first shaft end portion 12 g of the motor shaft 12 and the side bearing 1 5) is D 2, it is desirable to satisfy the following two relations at the same time. 1.5 $ (Dl / d) S 3 ’and

Description of the invention (16) 1.5 '(D2 / d) S 3 In addition, the fitting surfaces of the first shaft end portion 8c of the mandrel 8 and the first shaft end portion 12g of the motor shaft 12 are fitted in the fitting portion. When the length in the axial direction is L, it is ideal that the above two relationships can satisfy the following relationship. (L / d) ^ 8 and satisfies these relationships, it brings about an appropriate deflection limiting effect and ease of formation and assembly of the fitting portion. When the cross-sectional shape of the first shaft end portion 8c of the mandrel 8 at the fitting portion is a non-circular cross-section of the shaft diameter d, the imaginary shaft diameter is calculated using the area moment of inertia determined by the cross-sectional shape. In the above-mentioned embodiment, the deflection limiting device has been described. The shaft end of the mandrel is inserted into a hole provided on the end face of the motor shaft to form the fitting portion. That is, the fitting portion may be formed by inserting a shaft end portion of the motor shaft into a hole provided on an end surface of the mandrel shaft. In the embodiment described above, the fitting portion of the mandrel 8 and the motor shaft 12 has been described as a hole type in which the front end portion of one shaft is fitted into the shaft provided on the other side. However, it is not limited to this. It is also possible to insert a common sleeve into the outer peripheral surface of the front end portion of the mandrel 8 and the outer peripheral surface of the front end portion of the motor shaft 12 in the sleeve. Those can also. In this case, an elastic body exists as necessary between the facing end face of the mandrel 8 axis and the end face of the motor shaft 12 or between each shaft and the inner peripheral surface of the sleeve. (Embodiment 1) 565525 V. Description of the invention (17) A specific embodiment of a winding device for lines shown in Figs. 1, 2 and 4 is shown. In this device, the shaft diameter D1 of the mandrel 8 is 25 mm, the shaft diameter d is 15.9mm, the hole diameter of the hole portion 12c of the motor shaft 12 is 16mm, and the shaft diameter D2 of the motor shaft 12 is 30mm. The ring-shaped elastic system is composed of NBR (nitrile butadiene rubber), 6 O-rings with a wire diameter of 2.4 mm, and is mounted on the first shaft end portion 8c of the mandrel 8 at a distance of 6 mm. To the bobbin holder 1, four round bobbins 18 having a width of 300 mm and an inner diameter of 125 mm were mounted. The total length of the bobbin is 1,200mm. The winding device of this line drives the motor 10 to raise the rotation of the bobbin holder 1. Here, the vibration of the bearing 15 portion of the motor shaft 12 was measured by a normal acceleration type vibration sensor mounted on the outer periphery of the motor 10. The measurement results are shown in Fig. 10. In Fig. 10, the number of rotations (unit: rpm) of the horizontal axis bobbin holder 1 and the vibration 値 (unit: ju m) measured by the vertical axis sensor. As shown in Fig. 10, the winding device of this line is capable of rotating to UJOOmirT1 with vibration (not exceeding the allowable vibration) in the range of 10 // m. When the number of rotations is converted into the winding speed of the line (circle speed of the tube 18), it is equivalent to 8,000 m / min. This state of affairs is a winding device for the line, which means that for the purpose of the present invention, the winding speed of the line can stably wind the line at a speed of 7,000 m / min or more. (Comparative example) The mandrel and motor shaft of the line take-up device of Example 1 and the joint portion of these shafts were replaced with the former shown in Figures 13 and 14 as -19-565525. Description of the invention (18) is the winding device of the previous line. The winding device for this line is the same as that of the first embodiment, and the motor 38 is driven to raise the rotation of the bobbin holder 30. During this time, the vibration of the motor shaft 39, the bearing 39b, and the like was measured by a normal acceleration-type vibration sensor mounted on the outer periphery of the motor 38. The measurement results are shown in Fig. 11. And in Fig. 11, the horizontal axis is the rotation number (unit: rpm) of the bobbin holder 1, and the vertical axis is the vibration 値 (unit ···· m) measured by the sensor. As shown in Figure 11, the winding device of this line is in a vibration range that does not exceed the permissible vibration range # 10 # m and can only rotate to ISSOOmirr1. This rotation number is equivalent to 6,900 m / min when the winding speed of the line is calculated (circle speed of the bobbin 100). This ratio is 1,100 m / min lower than 8,000 m / min in Example 1, and does not reach a speed of 7,000 m / min or more, which is the purpose of the present invention. (Example 2) In the winding device for the line used in Example 1, the above-mentioned shaft diameter D1 was changed, and the shaft diameter d and the shaft diameter D2 were changed into various forms. The rotation of the bobbin holder 1 was raised in the same manner as in Example 1. The results are shown in Table 1. ^ According to Table 1, in the condition of any combination, the bobbin holder 1 is shown to be rotatable to 18900min_1 within the allowable vibration range.
