Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a twisted yarn winding device capable of twisting yarn and directly winding it onto a large-diameter bobbin to form cheese.

Conventionally, in order to obtain cheese by winding twisted yarn onto a bobbin as a final product, it was necessary to wind the yarn onto the bobbin once during the twisting process, and then unwind it onto a large-diameter bobbin, which required a lot of work. This required a lot of effort and time. This is because the pressure applied to the wound layer changes as the winding diameter changes when the yarn is twisted by a twisting machine and wound onto a bobbin while giving a traversing motion to the yarn. This is because the thread could not be directly wound onto a large diameter bobbin because the thread layer would collapse.

In the present invention, when winding the twisted yarn onto a bobbin while twisting the yarn, the bobbin or the wound yarn layer on its circumference is always pressed with a constant force regardless of changes in the winding diameter. The present invention is characterized in that by providing a device for winding the twisted yarn, the yarn can be directly wound onto a large-diameter bobbin without problems such as yarn breakage.

The illustrated embodiment will be explained below. Reference numeral 1 denotes a flyer of a twisting machine, and here a pair of flyers 1,
1 are arranged so as to be interlocked. These have similar configurations, so to explain one, yarn 2
A shaft 4 having a hole 3 for feeding the air is inserted into one support shaft 5 of the fryer 1, and is connected to the support shaft 5 via a series of gears 6, and
It is connected via a planetary gear mechanism 7 to several pairs of capstan rolls 8 provided within the fryer 1.

Inside the fryer 1, a core rod 9 and a fundo pipe 10 rotatably mounted on the core rod 9 are provided, passing through the other support shaft portion 11 of the fryer 1, and one end of the core rod 9 is inserted through an arm member 12. and is fixed to the capstan roll 8. Fundo pipe 1
A bobbin 13 is fixed to the flyer 1, and the yarn 2 passes through the hole 3 of the shaft 4 and is wound around the circumferential surface of the capstan roll 8. After that, the yarn 2 passes through the hole 3 of the shaft 4 and is wound around the circumferential surface of the capstan roll 8. It is guided onto the circumference of the bobbin 13 via rollers 15 and 16.

A belt 19 is stretched between pulleys 18, 18 fixed to the support shafts 11, 11 of both flyers 1, 1, and a belt 20 is stretched between one pulley 18 and a pulley 21 fixed to a driving shaft 22. As a result, both fryers 1, 1 are rotated periodically by the driving shaft 22.

The bobbin 13 is moved to the flyer 1 by the tension of the yarn 2.
A pulley 23 is attached to the circumferential surface of the fundo pipe 10, which is integral with the bobbin 13, so as to be displaceable in the axial direction. A wheel 24 is integrally provided, and the brake wheel 24 is appropriately braked by a brake belt 26 equipped with a weight 25. Here, by adjusting the load of the weight 25, the rotation speed of the bobbin 13 can be adjusted, that is, the tension of the yarn 2 can be adjusted.

27 is a differential device, which is connected to pinion shafts 28, 2.
8 and the pinion shaft 2
The rotation of the driving shaft 22 is transmitted to the housing 29 via a pulley 34, a belt 35, and a pulley 36. The rotation of the fundo pipe 10 is transmitted to the shaft 32 via the pulley 23, belt 37, and pulley 38, and the shaft 33 transmits the rotation speed difference between the housing 29 and the shaft 32, that is, the difference in the rotation speed between the flyer 1 and the bobbin 13. It is designed to be rotated according to the

The shaft 33 is connected to a series of gear mechanisms 39, pulleys 40,
A protrusion (not shown) on the inner surface of a cylinder 45 is connected to a camshaft 44 having a spline-shaped groove 43 carved on its circumference through a belt 41 and a pulley 42, and the camshaft 44 is loosely inserted into the groove 43. camshaft 44
When the cylindrical body 45 rotates, the cylindrical body 45 reciprocates along the camshaft 44.

Arm rods 46, 46 project from the left and right sides of the cylinder 45 and fit into the recess 47 at the end of the fund pipe 10.
When the cylindrical body 45 moves, the fund pipe 10 also reciprocates along the core rod 9 following the movement of the cylindrical body 45.

In the above components, the bobbin 13 rotates following the flyer 1 due to the tension of the yarn 2, so as the yarn 2 is wound into multiple layers, the rotation speed of the bobbin 13 approaches the rotation speed of the flyer 1. In this case, since the rotation of the shaft 33 also becomes slow, the displacement of the bobbin 13 linked to this shaft 33 also becomes slow.

The apparatus of the present invention is provided with a winding pressure adjusting device 48 on the rod 14 of the flyer 1, which receives the yarn 2 from the guide roller 16 and guides it onto the circumference of the bobbin 13. As shown in FIGS. 2 and 3, this winding pressure adjustment device 48 includes a shaft tube 49 rotatably held by the rod 14 of the flyer 1, and a thread extending from the shaft tube 49 in the direction of the bobbin 13. A guiding arm 50, a pressing surface portion 51 formed at the tip of the yarn guiding arm 50 and pressed against the bobbin 13 or the winding layer on the circumference thereof, a yarn guide hole 52 provided in the pressing surface portion 51, and a yarn guide hole 52 provided in the pressing surface portion 51. It consists of a guide arm 50 and a balance weight 53 protruding from the shaft cylinder 49 on the opposite side, and the guide roller 16 is mounted on the shaft cylinder 49.

In the apparatus of the above embodiment, when the flyer 1 is rotated, the bobbin 13 reciprocates while rotating as described above, and the yarn 2 passed through the thread guide hole 52 is twisted and wound around the bobbin 13. However, the outer surface of the thread layer is pressed against the pressing surface portion 5 of the thread guiding arm 50.
1, the yarn is constantly pressurized to prevent the yarn from collapsing.
Moreover, as the diameter of the wound yarn layer increases, this pressing surface portion 51 gradually moves away from the rotation axis, and as shown in FIG. 2, the balance weight 53 approaches the rotation axis. The centrifugal force generated at 53 gradually decreases, which acts to reduce the pressure applied to the wound yarn layer. Therefore, by adjusting the position and mounting angle of the balance weight 53, the weight of the balance weight 53, etc. in advance, the pressure applied from the pressing surface portion 51 to the wound yarn layer from the beginning of winding to the end of winding can be controlled. By applying a constant pressure to the yarn layer at all times, yarn can be wound onto the bobbin while preventing problems such as yarn collapse.

It goes without saying that the present invention can also be applied to an apparatus that twists a plurality of yarns into one yarn, and then twists and winds the yarn.

As explained above, the present invention allows the bobbin to wind the yarn while constantly applying a constant pressure to the winding layer, so the yarn can be wound directly onto the large diameter bobbin without causing problems such as yarn collapse. You will be able to get the final product. Therefore, unlike in the past, there is no need to rewind the material that has been wound onto a small diameter bobbin in the twisting process onto a larger diameter bobbin as the final product, which simplifies the process and makes it possible to use a rewinding bobbin. You will be able to turn it off if it is no longer needed.

Moreover, according to the present invention, by adjusting the relative position of the pressing surface of the winding force adjusting device with respect to the shaft cylinder and the balance weight, as well as the shape, weight, etc. of the balance weight, the diameter of the bobbin to be applied and the winding layer thickness can be adjusted. This means that the optimum pressing force can be easily obtained.
