The present invention relates to a double twist spindle with a winding device for a twisted yarn and a tire cord, wherein the twisted yarn and the plurality of yarn strands which are not firstly twisted are collected and secondly twisted.

Conventionally, as a twisting machine of synthetic fibers for industrial materials, mainly for tire cords, each yarn is individually twisted to a plurality of thread strands, and the first twist is performed, and the first twisted yarn strands are collected and wound twice. The step of winding the device on a single loom is generally known as being spread as a direct rolling machine (direct gebra).

Compared to the case where the primary twisting yarn and the secondary twisting spindle adopt the double twisting spindle in this direct-weaving machine, compared with the use of another ring twisting spindle, etc., the twisting efficiency is good and the productivity is very high. It has been proposed to incorporate a winding device on a secondary double twist spindle in this direct-winding machine (for example, Japanese Unemployment Office 56-38693, Japanese Unemployment Office 61-6173, Japanese Unexamined Patent Application 57-42931). ). The winding bobbin of the double twist spindle with a winding device is configured to be actively driven directly from the driving source. Therefore, the drive source of the winding bobbin is installed so as to face the permanent magnet mounted on the driving side and the magnetic plate on the driven side, and transmits the rotational force in a non-contact manner, accompanied by a change in the rotational speed according to the change in the winding diameter. The mounting rollers are brought into contact with the tip of the rotating arm on the surface of the wound chamber to be in accordance with the change in the tensile force of the bobbin caused by the change in the winding diameter, and at the same time as the rotational speed corresponding to the winding diameter. As a detection signal, the gap between the permanent magnet and the magnetic plate is adjusted according to the change of the winding diameter so that the thread is always wound under a constant tension, and when the initial winding tension is set, the gap between the magnets is changed every time the changing mechanism is set. It is configured to adjust.

However, such a double twist spindle with a winding device employs a mechanism for actively driving the winding bobbin itself directly from its driving source, which has the following problems.

In other words, in order to wind the winding strands at a constant speed in order to actively wind the winding bobbin, it is necessary to reduce the number of turns of the winding bobbin according to the increase of the seal layer of the package. It is necessary to cope by reducing the drive rotational power by increasing the distance of the pair of magnets.

However, in reality, the package also increases its own weight as the thread is wound, so it is necessary to increase the driving rotational force to wind the winding bobbin with increased weight to a certain winding tension. Then, the driving torque is decreased to decrease the number of rotations with the increase of the wound thread layer, while adjusting the rational betrayal technical task of increasing the driving rotational force to wind up with the constant winding tension with the increase of the self weight. Corresponds by reducing the gap of magnets However, since the drive rotational force of the winding bobbin changes in one dimension, the drive rotational force due to the adjustment of the magnet spacing changes in two dimensions, and is actually wound due to the inadequate relationship between these adjustments. There was a problem that the tension is increased and the thread is cut or twisted.

Therefore, it is an object of the present invention to solve the above problems by employing the following means.

That is, first, the winding bobbin is installed freely on the spindle. It is driven by an appropriate transmission means by a mechanical drive source between a bolster flange portion for supporting the hollow spindle blade having a center hole through which a thread is inserted, and a seal storage rotating plate fixed to an outer circumference of the hollow spindle blade. Drives with permanent magnets are rotatably installed around the bolster. A driven member having a permanent magnet opposed to this driving member is installed to be rotatable around the above-described hollow spindle blade at appropriate intervals by sandwiching the above-described actual storage rotary plate.

In addition, the driven shaft driven as a power source is rotatably supported on a stop plate opposed to the above-described hollow spindle in parallel with the hollow spindle blade, and at one end of the drive shaft, A guide roller and an overfeed roller are guided to the traverse device to guide the combined thread strands through the center hole to the winding bobbin. In addition, by installing a drive roller with a suitable conductive means in the middle of the drive shaft described above, the drive roller rotates to always press the surface according to the winding diameter and change of the winding bobbin rotatably mounted on the upper end of the hollow spindle described above. If possible, it is supported.

Since the winding bobbin built into the spindle and passively rotating freely is driven by the surface friction driving method with the driving roller, even if the winding progresses and the winding diameter of the package increases, the winding bobbin always winds at a constant winding speed as the driving roller rotates. Moreover, the drive body and the driven body using a pair of permanent magnets serving as the drive source are driven with a constant rotational force without any change.

The spur gear is a bobbin holder. (39) It is fixed. The above-described bobbin holder 39 is formed into a cylindrical body, and the inside thereof is formed in a hollow so that the hollow tube part of the support 14 described above is mounted on the hollow part, and rotation is performed through the bearing 40 (see FIG. 1). It is freely mounted. Reference numeral 41 denotes a basket-shaped spring fitted to the outer circumference of the bobbin holder 39, in which the winding bobbin 42 is fitted to fix the winding bobbin.

One example of a device embodying the present invention is constructed as described above, and the following describes the operation of the device, the hollow spindle blade 1 in FIG. 1 is timingd by a mechanical drive source (not shown). The timing pulley 2 is driven through the belt to rotate in the bolster 3. For this reason, the circular real storage rotating plate 1b fixed to the hollow spindle blade 1 rotates. Even when the hollow spindle 1 and the actual storage rotary disk 1b rotate, the stop plate 12 maintains its stop state due to its own weight and weight 13.

On the other hand, the drive body 6 having a permanent magnet is driven through the timing belt 9 by a mechanical drive source and rotated at the outer periphery of the bolster 3 to fit the bottom plate of the actual storage rotating plate 1b, and is suitable. At intervals, the driven body 10 facing the drive body 6 is driven to rotate at the outer periphery of the spindle blade 1. When the driven body 10 rotates, the drive shaft 14 rotates through the timing belt 18 fitted with the timing pulley 17 attached to the driven body 10.

Therefore, when this drive shaft 14 rotates, the drive roller 27 rotates through the timing belt 26 engaged with the timing pulley 24 attached to this drive shaft 14. As a result, the winding bobbin 42, which is always in pressure contact by the drive roller 27 and the pressure contact mechanism 31, is perforated with the surface frictional force. Moreover, the roller 22 attached to the front-end | tip part of this drive shaft 14 is also driven.

On the other hand, when the winding bobbin 42 is driven because the bobbin holder 39 is fixed to the winding bobbin 42 by the spring 41 of the basket shape, the spur gear 38 attached to the bobbin holder 39, The deceleration mechanism 36 and the beret gear 34 and 35 are driven through the spur gear 37, and as a result, the traverse camshaft 32 is driven so that the traverse guide mechanism 33 performs a curved motion. By the way, the first strand or the first strand not yarn (Y) is combined and guided to the thread storage rotating plate (1b) while drawing a balloon shape through the thread eye (43). Subsequently, the thread strand Y is turned about 1/2 to 2 times around the outer periphery of the bottom of the actual storage rotating plate 1b, and the center of the bobbin holder 39 is passed through the central hole 1a of the hollow spindle blade 1. It is guided to the guide roller 23 through. Therefore, the secondary twisting of the thread strand is performed between the above-mentioned one eye 43 and the guide roller 23. Thus, the thread strand Y passing through the guide roller 23 is pulled out by the overfeed roller 22 and wound around the winding bobbin 42 via the traverse guide mechanism 33.

Even if the winding progresses and the winding diameter of the winding bobbin 42 increases, the driving roller 27 receives pressure as the winding diameter increases, and the arm 29 rotates, so that the driving roller 27 attached to the arm 29 is rotated. The thread strand (Y) is always wound on the bobbin (42) at a constant speed because it is always in contact with the cold bobbin (42).

According to the present invention, the winding bobbin built in the double twist spindle is rotatably installed on the stationary plate, and at the same time, the driving roller contacting the winding bobbin at a predetermined pressure is rotated according to an increase in the wound diameter of the package. In addition, the drive roller is driven by a drive source having a pair of permanent magnets as a power source, and the winding speed is always constant even if the diameter of the package is increased, compared to driving the winding bobbin itself by the drive source. The instability of the winding tension caused by the deceleration of the supplied thread strand and the winding bobbin is completely eliminated, and there is an effect such that a complicated mechanism for winding the coil at a constant tension and adjusting the magnet spacing is unnecessary.
