Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a balloon spinning control device for a spinning machine such as a ring spinning machine and a ring twisting machine in which a balloon control ring (anti-node ring) is integrally and movably fixed to a ring rail. .

[0002]

2. Description of the Related Art Generally, in this type of spinning machine, in order to form a yarn, the ring rail is gradually raised while repeating the vertical movement of the ring rail during operation of the machine base, and the lappet angle and balloon control are synchronized with it. Raise and lower the ring etc. The balloon control ring prevents excessive outward bulging (balloon) between the snell wire and the traveler during spinning. Then, it prevents the yarns of the adjacent weights from interfering with each other due to the enlargement of the balloon, and regulates the balloon to a size suitable for sliding on the ring flange in a stable state of the traveler.

Conventionally, as for the raising / lowering method of the balloon control ring, there are a method of raising / lowering the balloon control ring integrally with the ring rail (integrated raising / lowering method) and a method of raising / lowering independently of the ring rail. In the integral lifting method, as shown in FIGS. 6A and 6B, the balloon control ring 31 is fixed to the ring rail 33 via a mounting piece 32. Then, while the ring rail 33 and the lappet angle 34 are repeatedly moved up and down by the action of the lifting mechanism (not shown) as the machine base is operated,
It gradually rises to the end of winding (full pipe) position shown in FIG. 6 (b).

The yarn Y sent from the front roller 35
Is a snell wire 37 fixed to a lappet 36 supported by a lappet angle 34 so as to extend horizontally.
Then, it is taken up by the bobbin B via the traveler 39 running on the ring 38 fixed to the ring rail 33. The balloon control ring 31 regulates the balloon 40 of the yarn Y between the snell wire 37 and the traveler 39. In order for the balloon control ring 31 to exert its effect better, the height from the ring 38 has an appropriate value, and the effect of the balloon control ring 31 is that the balloon 40 is unstable from the beginning of winding to about 5 minutes. Expected in.

Further, as a balloon control ring that can be raised and lowered independently of the ring rail, Japanese Patent Laid-Open No.
Japanese Unexamined Patent Publication No. 27130 discloses a device provided with two line shafts and independently raising and lowering a ring rail, a lappet angle and a balloon control ring.

Further, Japanese Utility Model Laid-Open No. 53-19028 discloses a set wire for a head twisting device in a spinning machine and a twisting machine as shown in FIG. That is, the lappet 43 is supported by the lappet bar 42 rotatably supported by the bracket 41 fixed to the machine base, and the head twisting device 44
Is attached to the lappet 43 in a bent state so as to extend downward from the base end thereof.

[0007]

If the lift length is relatively short, there is no problem with the integrated lifting system. However, when a long bobbin is used to increase the lift length, there is a problem that it is difficult to properly perform balloon control in the entire range of the lift length by the integral lifting method. This is because the snell wire 37 is fixed to the lappet 36 so as to extend horizontally. Therefore, in order to prevent the balloon control ring 31 and the snell wire 37 from interfering with each other at the winding end position shown in FIG. There is a constraint on the maximum height H0. However, the height Hb suitable for the beginning of winding when the balloon 39 is easily collapsed is higher than the maximum value H0, and when the height of the balloon control ring 31 is set to H0, the optimum state is not obtained, and the balloon does not start at the beginning of winding. It becomes unstable, and unevenness in yarn quality and yarn breakage occur.

In order to avoid the interference between the balloon control ring 31 and the snell wire 37 at the end of winding, it is conceivable to increase the initial position and the highest rising position of the snell wire 37. However, if the initial position of the snell wire 37 is increased, the height of the balloon 39 in the initial stage is also increased, and it is necessary to increase the height of the balloon control ring 31. In addition, the distance between the snell wire 37 and the front roller 35 at the highest position is reduced, which impairs workability during yarn splicing work.

Japanese Utility Model Laid-Open No. 53-19028 discloses that the set wire 42 for supporting the head twisting device 41 is not extended horizontally from the lappet but is bent so as to extend immediately downward from the base end. There is. However, nothing is described about the interference between the snell wire and the balloon control ring, which is the problem of the present invention. Further, even if the snell wire 37 of a ring spinning machine or the like is bent so as to extend downward from the vicinity of its proximal end like the set wire disclosed in this publication, interference between the snell wire 37 and the balloon control ring 31 is avoided. It is not possible.

On the other hand, in the device disclosed in Japanese Patent Laid-Open No. 3-27130, the balloon control ring 31 can be raised and lowered independently of the ring rail 33. Therefore, as shown in FIG. 8, even if the initial position of the balloon control ring 31 is set to a height Hb suitable for winding start, the height of the balloon control ring 31 at the end of winding should be a height that does not interfere with the snell wire 37. Can be lifted up and down. However, a mechanism for raising and lowering the balloon control ring 31 independently of the ring rail 33 is required, and there is a problem that the structure becomes complicated. There is also a problem that it takes time to apply it to an existing machine base.

The present invention has been made in view of the above problems, and an object thereof is to make it possible to set the winding start position of the balloon control ring to a highly effective height by balloon control with a simple structure. It is to provide a spinning ballooning control device that can be easily applied to an existing machine base.

[0012]

In order to achieve the above object, according to the invention of claim 1, in a spinning machine in which a balloon control ring is integrally and movably fixed to a ring rail, the spinning machine is independent of the ring rail. Between the thread guide part and the base end part of the snell wire fixed to the lappet supported by the lappet angle that is lifted up and down by at least a distance equal to the radius of the balloon control ring from the center of the thread guide part. The bent portion is provided so that the height is higher than the thread guide portion.

According to the second aspect of the present invention, the snell wire is formed in a bent shape so that a side view thereof has a crank shape and a yarn guide portion is lower than a base end portion. According to a third aspect of the present invention, in the first aspect of the present invention, the bent portion is formed so that its top portion is higher than both of the thread guide portion and the base end portion, and the bent portion is provided with a support portion of the balloon control ring. It has a shape extending downward from the connecting portion with the balloon control ring so as not to interfere with the bent portion.

[0014]

According to the invention described in claims 1 to 3, the ring rail and the lappet angle are independently raised from the winding start position to the winding end position while being repeatedly moved up and down, and gradually raised in a synchronized state. The ring is raised and lowered integrally with the ring rail. As the winding progresses, the distance between the balloon control ring and the snell wire gradually decreases, and the balloon control ring becomes higher than the thread guide portion of the snell wire near the end of winding. Since the snell wire has a bent portion between the thread guide portion at the tip and the base end portion, the height at a position separated from the center of the thread guide portion by a distance equal to the radius of the balloon control ring is higher than that of the thread guide portion. The balloon control ring is arranged at a position corresponding to the bent portion near the end of winding, and interference between the snell wire and the balloon control ring is avoided.

According to the second aspect of the present invention, the balloon control ring and its supporting portion are brought into a state corresponding to the crank-shaped bent portion of the snell wire when the winding end is approached.

In a third aspect of the invention, the bent portion of the snell wire is formed such that its top is higher than both the thread guide portion and the base end portion, and the support portion of the balloon control ring extends downward. It has a shape. Therefore, even if the positions of the yarn guide portion and the base end portion of the snell wire are the same height, the balloon control ring can be arranged at a position higher than the yarn guide portion without interfering with the snell wire.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment embodying the present invention will now be described with reference to FIGS.
It will be described with reference to FIG. As shown in FIGS. 1A and 1B, the support arm 2 is fixed to the upper end of the pillar 1 that is lifted and lowered by a lifting mechanism (not shown), and the ring rail 3 is fixed to the upper surface of the support arm 2. There is. A ring 5 for guiding the traveler 4 is fixed in a fitting hole formed in the ring rail 3 at a predetermined pitch. The rear portion of the ring rail 3 is bent upward at a right angle so that the mounting portion 3a
Are formed. A balloon control ring 6 is fixed to the mounting portion 3a by a screw 9 so as to correspond to each spindle 8 supported by a spindle rail 7. The balloon control ring 6 has a supporting portion 6a extending substantially horizontally, and the supporting portion 6a is fixed to a mounting piece 10 fixed to the mounting portion 3a with a screw 9.

Above the balloon control ring 6, a snell wire 12 for guiding the yarn Y sent from the front roller 11 is arranged so as to be able to move up and down. Snell wire 12 is fixed to lappet 13 and lappet 1
Reference numeral 3 is supported by a lappet angle 15 fixed to a pillar 14 that is moved up and down independently and in synchronization with the pillar 1 that supports the ring rail 3. As shown in FIGS. 2 (a) and 2 (b), the snell wire 12 has a thread guide portion 12a formed at the tip thereof, the side view thereof has a crank shape, and the thread guide portion 12a has a base end portion 12b. It is bent so as to be lower. Also, the thread guide portion 1
2a and the center of the balloon control ring 6 are arranged on the same straight line. The bent portion 12c is formed such that the height at a position separated from the center of the thread guide portion 12a by a distance equal to the radius of the balloon control ring 6 is higher than that of the thread guide portion 12a.

Ring rail 3 and lappet angle 15
Is a known lifting device (for example, JP-A-62-133).
No. 129), they can be raised and lowered independently of each other and in a synchronized state.

Next, the operation of the above-configured device will be described. As shown in FIG. 1 (a), at the start of winding,
The ring rail 3 is arranged such that the position of the traveler 4 corresponds to the start of winding the bobbin B. The height from the upper surface of the ring 5 to the thread guide portion 12a at the start of winding,
The height from the upper surface of the ring 5 to the thread guide portion 12a at the end of winding (full tube) is set to be the same as the conventional one. The height from the upper surface of the ring 5 to the balloon control ring 6 at the start of winding is set to a height Hb suitable for the beginning of winding when the balloon 16 easily collapses. That is,
At the end of winding, the height Hb is such that the height of the balloon control ring 6 is the thread guide portion 12a of the snell wire 12.
Is set to a value equal to or higher than the height of.

From this state, the operation of the spinning machine is started.
When the operation of the machine base is started, the bobbin B is rotated together with the spindle 8, and the yarn Y sent out from the front roller 11 passes through the snell wire 12 and the traveler 4 and then the bobbin B.
To be wound up. The yarn Y bulges outward between the yarn guide portion 12a and the traveler 4 around the spindle 8 and a balloon 16 is formed between the yarn guide portion 12a and the traveler 4. Ring rail 3 and lappet angle 1
5 is independent of each other by the action of the lifting device,
Figure 1
It is raised to the winding end position shown in (b). The balloon control ring 6 moves up and down integrally with the ring rail 3.

Since the height of the balloon control ring 6 at the start of winding is set to a height Hb suitable for preventing the collapse of the balloon 16, the balloon 16 is unstable at the initial stage of winding unlike the conventional case. Is suppressed. As a result, unevenness in yarn quality and yarn breakage due to instability of the balloon 16 are prevented.

Since the balloon control ring 6 moves integrally with the ring rail 3, as shown in FIG. 3, the balloon control ring 6 from the beginning of winding to the end of winding.
The rising amount L1 of the ring rail 3 is the same as the rising amount L2 of the ring rail 3, and the height of the balloon control ring 6 becomes equal to or higher than the height of the thread guide portion 12a near the end of winding. In the conventional device, since the snell wire 12 is formed to extend horizontally from the lappet 13, when the balloon control ring 6 reaches the position corresponding to the snell wire 12, the two interfere with each other, and the balloon control ring 6 is positioned higher than the snell wire 12. I couldn't move. Therefore, conventionally, the balloon control ring 6
As shown by the chain line in FIG. 3, the initial position of the balloon control ring 6 was set so as to move to a lower position than in the case of this embodiment.

However, in this embodiment, the thread guide portion 12a
The snell wire 12 is bent in a side crank shape so that the position is below the base end 12b, and the tip side of the snell wire 12 is located inside the balloon control ring 6 near the end of winding. Becomes Therefore, the balloon control ring 6
Can be arranged at a position higher than the thread guide portion 12a without interfering with the snell wire 12.

That is, in this embodiment, the position and the amount of lifting of the thread guide portion 12a of the snell wire 12 are not changed from those of the conventional device, but in the structure of the conventional device, the snell wire 1 is wound at the end of winding.
Even if the initial position of the balloon control ring 6 is set to a height in which the balloon control ring 6 is in a state of interfering with 2, the interference between the snell wire 12 and the balloon control ring 6 can be avoided. Therefore, attach the balloon control ring 6 to the ring rail 3
In contrast, the height of the balloon control ring 6 can be set to an appropriate height at the beginning of winding without providing a drive mechanism for independently moving up and down (relative movement).

If the balloon control ring 6 is located above the thread guide portion 12a, it cannot perform its function. However, originally, the balloon control ring 6 exerts its function effectively from the beginning of winding to about 5 minutes, and when the distance between the ring 5 and the lappet 13 is shortened, the diameter of the balloon 16 becomes smaller than that of the balloon control ring. It is smaller than the diameter and does not fulfill its function. Therefore, there is no problem even if the balloon control ring 6 is arranged above the thread guide portion 12a near the end of winding.

The balloon control ring 6 has a simple structure in which the shape of the snell wire 12 is changed.
It can be easily applied to an existing machine stand, as compared with the case where a drive mechanism for moving relative to the ring rail 3 is provided.

Further, in this embodiment, since the snell wire 12 is formed so as to have a side crank shape, its processing is extremely simple. The present invention is not limited to the above embodiment, and may be embodied as follows, for example.

(1) As shown in FIG. 4, the bent portion 12c of the snell wire 12 is formed so that its top is higher than both the yarn guide portion 12a and the base end portion 12b. The support portion 6a of the balloon control ring 6 is shaped so as to extend downward from the connection portion with the balloon control ring 6 so as not to interfere with the bent portion 12c.
In this case, the initial position of the balloon control ring 6 can be set higher than in the above-described embodiment without changing the positions of the lappet 13 and the thread guide portion 12a.

(2) The mounting position of the mounting piece 10 with respect to the ring rail 3 is configured to be vertically movable, and the configuration of (1) is adopted. As means for making the movement adjustable, for example, a mounting portion 3a of the ring rail 3
An elongated hole extending in the up-down direction is formed at the position, so that the fixing position by the screw 9 can be changed. In this case, the initial position of the balloon control ring 6 can be set to an appropriate height over a wide range of the length of the bobbin B to be used.

(3) The shape of the snell wire 12 is to prevent interference with the balloon control ring 6 between the thread guide portion 12a and the base end portion 12b. Therefore, at least the radius of the balloon control ring 6 from the center of the thread guide portion 12a. The height at the position separated by a distance equal to
Any shape may be used as long as it has a higher bent portion. For example, in (1), the positions of the yarn guide portion 12a and the base end portion 12b may be the same height. in this case,
The initial position and the final position of the lappet 13 can be set to the same positions as in the conventional case.

(4) The shape of the ring rail 3 is not limited to that of the embodiment. For example, as shown in FIG. 5, a ring rail 3 having an inverted U-shaped cross section is used, and the ring rail 3 is used.
The bracket 17 may be projected at a position corresponding to each ring 5 above, and the balloon control ring 6 may be fixed to the bracket 17.

(5) Not limited to the ring spinning machine, it may be applied to a ring twisting machine. Inventions other than those described in the claims that can be grasped from the embodiments and modifications will be described below along with their effects.

(1) In the invention described in claim 3, the balloon control ring is attached to the ring rail in a height position adjustable manner. In this case, the bobbin B to be used
Even if the length is changed in a wide range, the initial position of the balloon control ring 6 can be easily set to an appropriate height.

[0035]

As described in detail above, claims 1 to 3 are described.
According to the invention described in (1), it is possible to set the winding start position of the balloon control ring to a height at which the effect of balloon control is better exhibited with a simple configuration, and it can be easily applied to an existing machine base. .

According to the second aspect of the invention, the processing of the snell wire is simplified. According to the third aspect of the invention, even if the positions of the thread guide portion and the base end portion of the snell wire are the same height, the initial setting position of the balloon control ring can be set to a higher position.
