Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention involves passing yarn drawn from a yarn bundle through a cylinder of a rotating shaft, and passing the yarn through the cylinder onto a winding rod. This invention relates to a yarn twisting device that twists yarn by winding it.

<Prior Art> Conventionally, an up-twister ring twisting machine has been used and generally known as a device for twisting yarn.

The former up twister twists the thread while pulling it out from a rotating bobbin on which the thread is wound.

The latter ring twister twists the yarn while winding it up, in contrast to the above-mentioned up twister. To explain in more detail, the thread guide rotates in the opposite direction to the bobbin and drives the outer periphery of the rotating winding bobbin up and down, and through the thread guide, the thread is evenly wound around the bobbin while being twisted and twisted into the thread. is multiplied by

<Problems to be Solved by the Invention> However, the above-mentioned up-twister ring twisting machine has the following problems.

(1) Since the thread is twisted while rotating the bobbin, only the amount of thread that is wound around the bobbin can be twisted.

(2) When the bobbin is rotated at high speed, balooning occurs in the thread due to the centripetal force.

(3) The bobbin in which the thread is wound has a heavy amount of Il, and
Since the volume is large, the holder that holds the bobbin is required to be large and durable.

b. A large load is applied to the rotating shaft that rotates the bobbin.

(4) As the amount of yarn wound around the bobbin decreases (in the case of an up twister) or increases (in the case of a ring twister), the load applied to the rotating shaft changes, making it impossible to twist the yarn at a constant speed. Can not.

The present invention was devised in view of the above, and an object of the present invention is to provide a yarn twisting device that has an extremely simple structure, rotates at high speed, and can twist yarns well at a constant speed. do.

Means for Solving the Problems> In order to achieve the above-mentioned objects, the present invention has a lid that is closed on one side,
A cylindrical body having a through hole formed in the faith position of the closing lid, and a winding rod that is formed coaxially with the cylindrical body and protrudes from the cylindrical body, and has a thread locking member formed at its tip. The rotating shaft is composed of a rotating shaft, a holding member that rotatably holds the rotating shaft, and a rotating means that rotates the rotating shaft.

<Example> An embodiment of the present invention will be described below based on the drawings.

FIG. 1 shows an overall perspective view of the present invention, and FIG. 2 is a longitudinal sectional view of the present invention.

The yarn twisting device 1 of Example A has a closed lid on one side, and the closing lid part 12
A cylindrical body 11 in which a through hole 13 is formed at one center position of the cylindrical body, and a thread locking member 16 that is formed coaxially with the cylindrical body 11 and protrudes from the closing lid part 12 of the cylindrical body, and has a thread locking member 16 at the tip end thereof. The rotating shaft 10 includes a formed winding rod 15, a holding member 20 that rotatably holds the rotation @h10, and a rotating means that rotates the rotating shaft 10.

More specifically, the cylindrical body 11 is formed into a cylindrical body having a circular cross section, and one end of the cylindrical body 11 is closed. This closing portion 12 is formed in a tapered shape, and the cylindrical body 11
A through hole 13 through which a thread inserted through the opening 14 passes through the cylindrical body 11 through the inside of the cylindrical body 11 is bored at an eccentric position of the closing lid part 12. A winding rod 15 that passes through the body 11 and winds the thread pulled out is connected to the cylinder body 1.
It is fixed coaxially with 1 and protrudes outward.

The through hole 13 is preferably provided adjacent to the outer circumferential surface of the winding rod 15 from the viewpoint of winding the thread pulled out through the through hole 13 around the winding rod 15.

The winding rod 15 is formed to have a triangular cross section, and a thread locking member 16 is formed at the tip of the winding rod 15 to prevent the thread wound around the winding rod 15 from coming off. The thread locking member 22 is formed into a flange shape. The winding rod 15 is preferably tapered from the viewpoint that the thread is drawn out while winding the winding rod 15. Furthermore, the cross-sectional shape of the winding rod is not particularly limited, and for example, , may have a circular or hexagonal cross section.

20 is a holding member that holds the rotating shaft 10, and the cylindrical body 11
A rotary shaft 10 is rotatably held at two locations, an upper portion and a lower portion.

A drive belt K is disposed between the holding members 20 so that the rotating shaft 10 can be rotated. This drive belt is driven in the direction of arrow A by a drive means (not shown).

A fixing plate 30 is fixed by connecting these two holding members 20. The fixing plate 3o fixes the twisting device 1 to a wall or the like.

Hereinafter, the operation of the yarn twisting device 1 having the above structure will be explained based on FIG. 3.

The yarn pulled out from the untwisted yarn bundle G is passed through the yarn guide 55, pin 54, and first feed roller section 50 consisting of rollers 51, 52, and 53 to the cylindrical body. 11 into the opening 14 and further through the through hole 13.
The strands are being pulled out. Each of these rollers 51.52
．． 53 is arranged in a triangular shape, and includes a roller 51 and a roller 52.
, and the thread is held between rollers 52 and 53,
When the thread is pulled out, each roller rotates and feeds the thread.

Further, the thread pulled out from the through hole 13 is wound around the winding rod 15 several times in a counterclockwise direction, and is taken up by a second feed roller section 60 (not shown), which is made up of rollers 61, 62, and 63. Leading to the bobbin.

At this time, the thread wound around the winding rod 15 is locked by the thread locking member 16 formed at the tip of the winding rod 15, so the thread is wound around the winding rod 15. Even when the thread is pulled out, the wound thread does not come off the winding rod 15, and further,
Rotate in the same direction as the thread winding direction (counterclockwise) 1iIllll
Even if O is rotated, the thread will not come off the winding rod 15.

Therefore, the thread pulled out from the cylinder 11 is pulled out from the winding rod 15 after being wound around the winding rod 15 four times.

The configuration of the second feed roller section 60 is as follows.
Same as 0.

The tension of the yarn is controlled by the difference in rotation between the first feed roller and the second feed roller.

In the above state, when the drive belt K is driven by a drive means (not shown), the drive belt is driven in the direction of arrow A, and the rotating shaft 10 is rotated in the direction of arrow B.

As the rotating shaft 10 rotates, thread is pulled out from the yarn bundle G, and the drawn thread passes through the rotating cylinder 11 via the thread guide 55, the bin 50, and the first feed roller section 50. At this time, a Z twist (left twist) is applied between the reference numerals CD, that is, between the portion where the yarn is held between the rollers 52 and 53 and the portion where the yarn is wound around the winding rod 15.

The thread passing through the cylinder body 11 is rotated by a winding rod 15.
is pulled out from the winding rod 15 while being wound four times. At this time, the Z-twisted thread that has penetrated through the cylinder 11 and is pulled out is twisted one time by 5174 threads (right-handed twist) when it rotates once from the part where it is wound around the winding rod 15. There will be no state.

The thread pulled out from the winding rod 15 passes through the second feed roller section 60 and is wound onto a winding bobbin (not shown). At this time, an S twist is applied between the symbol EL in the figure, that is, between the part where the thread is pulled out from the winding rod 15 and the part where the thread is held between the rollers 61 and 62. This right-twisted state is wound onto a winding bobbin (not shown).

Therefore, when the rotating shaft 11 rotates once while the thread is being pulled out, the thread between symbols CD is twisted once, and the thread between symbols DE is untwisted.
One twist is applied between the symbols EL.

In the above embodiment, the thread was wound around the winding rod four times, but the number of windings is not particularly limited, but from the viewpoint of frictional resistance between the winding rod and the yarn, it is recommended that the thread be wound around 2 to 6 times. preferable.

In addition, the rotating shaft is rotated counterclockwise and the thread rotates around the winding rod counterclockwise each time, so that the thread is twisted to the right, but it goes without saying that the reverse is also possible. .

<Effects of the Invention> As explained above, the yarn twisting device of the present invention includes a cylinder whose end is closed and a through hole is formed in the closed lid, and which is formed coaxially with the cylinder. It is composed of a rotating shaft consisting of a winding rod having a thread locking member formed on its portion, a holding member that rotatably holds the rotating shaft, and a rotating means for rotating the rotating shaft.

Therefore, the yarn twisting device according to the present invention exhibits the following effects.

(1) Since the yarn twisting device and the yarn bundle are independent, it is possible to connect the end of each yarn bundle to the tip and twist the yarn continuously.

(2) It is possible to use a yarn bundle with a heavy yarn weight or a yarn bundle with a large volume.

(3) Burloning phenomenon does not occur.

(4) Since the load of the bobbin is not applied to the rotating shaft, twisting can be applied at a constant rotational speed.

Therefore, due to the above effects, a much higher production capacity can be obtained compared to the conventional method.
