Abstract
Description
- The invention relates to a synthetic yarn splicer.
- As a conventional synthetic yarn splicer, for example, one described in Patent Literature 1 (Japanese Unexamined Patent Publication No.
H10-17214 Patent Literature 1, a starting end and a terminating end of two synthetic yarns are aligned in the opposite directions to be drawn into an air nozzle, both side portions outside the air nozzle of the drawn yarn end are pressed down, the pressed both side portions are moved into the air nozzle, the aligned yarn end is loosened inside the air nozzle, and the yarns are spliced by an air flow inside the air nozzle. - The synthetic yarn splicer is used to splice a terminating end of a yarn of one supply bobbin and a starting end of a yarn of the other supply bobbin in, for example, a yarn winding machine for winding synthetic fibers. In the yarn winding machine, the yarn is wound around a bobbin while applying a tension to the yarn to form a package. For that reason, an entangled portion obtained by splicing the yarns by the synthetic yarn splicer is pulled while a tension is applied thereto. In the yarn winding machine, when the entangled portion is unwound during the winding operation, the winding operation must be temporarily stopped and hence the production efficiency is lowered. For that reason, there is a demand for forming an entangled portion having a tensile elongation capable of withstanding a winding tension in the synthetic yarn splicer.
- An aspect of the invention is to provide a synthetic yarn splicer capable of suppressing a change in tensile elongation decrease amount while suppressing a decrease in tensile elongation of an entangled portion.
- A synthetic yarn splicer according to an aspect of the invention is a synthetic yarn splicer that performs a splicing operation between one yarn and the other yarn formed of synthetic fibers, including: a yarn splicing portion that includes a passage which forms a space through which one yarn and the other yarn are insertable and an injection hole which opens to the passage and injects a fluid; and a pair of clamping mechanisms that is provided at a position interposing the passage of the yarn splicing portion and holds each of one yarn and the other yarn inserted through the space, in which a cross-sectional shape of the passage formed on a plane orthogonal to a penetration direction of the passage is a circular shape, and in which a first line passing through a center of the passage and connecting an inner peripheral surface of the passage and a second line passing through the center of the passage, connecting the inner peripheral surface of the passage, and orthogonal to the first line are equal to or larger than 4.0 mm and equal to or smaller than 7.0 mm.
- In the synthetic yarn splicer according to an aspect of the invention, the first line and the second line are equal to or larger than 4.0 mm and equal to or smaller than 7.0 mm. In the synthetic yarn splicer, since the first line and the second line are set to be equal to or larger than 4.0 mm, it is possible to suppress an influence of a contact with the inner surface of the passage when one yarn and the other yarn are swayed inside the passage by using the clamping mechanism as a fixed point. Further, in the synthetic yarn splicer, when the first line and the second line become larger than 7.0 mm, a fluid hardly acts on one yarn and the other yarn inside the passage and hence the entangled portion is not appropriately formed. Thus, in the synthetic yarn splicer, since the first line and the second line are set to be equal to or larger than 4.0 mm and equal to or smaller than 7.0 mm, the entangled portion can be appropriately formed. As a result, in the synthetic yarn splicer, it is possible to suppress a change in tensile elongation decrease amount while suppressing a decrease in tensile elongation of the entangled portion.
- In one embodiment, the injection hole may have a circular shape and a diameter of the injection hole may be equal to or larger than φ0.8 mm and equal to or smaller than φ2.0 mm. In this configuration, it is possible to suppress a change in tensile elongation decrease amount while suppressing a decrease in tensile elongation of the entangled portion.
- In one embodiment, the diameter of the injection hole may be equal to or larger than φ1.0 mm and equal to or smaller than φ1.8 mm. In this configuration, it is possible to further suppress a change in tensile elongation decrease amount while suppressing a decrease in tensile elongation of the entangled portion.
- According to an aspect of the invention, it is possible to suppress a change in tensile elongation decrease amount while suppressing a decrease in tensile elongation of an entangled portion.

chamber 14 is a passage through which a first yarn Y1 and a second yarn Y2 are inserted. As illustrated inFIG. 5 , thechamber 14 penetrates oneside surface 12b and theother side surface 12c of theyarn splicing nozzle 12. Thechamber 14 forms a space through which the first yarn Y1 and the second yarn Y2 are insertable. As illustrated inFIG. 4 , a cross-sectional shape of thechamber 14 formed in a plane orthogonal to the penetration direction of thechamber 14 is a circular shape. A circular shape includes a true circular shape, an oval shape, and the like.

Specifically, as illustrated inFIG. 2 , a base end portion of the support portion 22 (one end portion of the longitudinal direction) is provided with ashaft 21. Theshaft 21 is fixed to a frame (not illustrated) or the like. Thesupport portion 22 swings about theshaft 21. Thesupport portion 22 moves between a second position P2 (seeFIG. 6B ) in which a front end portion (the other end portion of the longitudinal direction) moves close to theyarn splicing portion 10 and a first position P1 (seeFIG. 6A ) in which the front end portion moves away from theyarn splicing portion 10 in relation to the second position P2. That is, thefirst clamping mechanism 20 moves between the first position P1 and the second position P2.

As illustrated inFIG. 2 , thefirst contact surface 27b and thesecond contact surface 27c are provided at a position in which at least the first clampingmember 24 and thesecond clamping member 26 contact. - As illustrated in
FIG. 5 , thefirst contact surface 27b is a flat surface which is continuous to one end of thesupport surface 27a (an end at the side of theside surface 22c). Thesecond contact surface 27c is a flat surface which is continuous to the other end of thesupport surface 27a (an end at the side of theside surface 22d). That is, respective surfaces are provided in order of thesecond contact surface 27c, thesupport surface 27a, and thefirst contact surface 27b from theyarn splicing portion 10 when viewed from the facing direction of the pair ofmain surfaces support portion 22. That is, thesecond contact surface 27c is disposed between theyarn splicing portion 10 and the clampingportion 23. Thesecond contact surface 27c is located at the inside of the facing direction of thefirst clamping mechanism 20 and thesecond clamping mechanism 30 facing each other with theyarn splicing portion 10 interposed therebetween and thefirst contact surface 27b is located at the outside of the facing direction. - The
first contact surface 27b is substantially parallel to themain surfaces first contact surface 27b is provided over thesupport surface 27a and theside surface 22c. Thesecond contact surface 27c is substantially parallel to themain surfaces second contact surface 27c is provided over thesupport surface 27a and theside surface 22d.

Each of the first clampingmember 24 and thesecond clamping member 26 is formed of, for example, metal such as SUS having abrasion resistance. The diameter of each of the first clampingmember 24 and thesecond clamping member 26 may be appropriately set. - The
first clamping member 24 and thesecond clamping member 26 are disposed at thesupport portion 22 so that respective end surfaces face each other. Specifically, the first clampingmember 24 is disposed at the side of the front end portion of thesupport portion 22 and thesecond clamping member 26 is disposed at the side of the base end portion of thesupport portion 22 in relation to the first clampingmember 24. Thefirst clamping mechanism 20 holds a yarn by clamping the yarn between the end surface of the first clampingmember 24 and the end surface of thesecond clamping member 26 in the clampingportion 23. - A part of the first clamping
member 24 is accommodated in thesupport portion 22 and a part of the first clampingmember 24 is exposed in theconcave portion 25 of thesupport portion 22. Thefirst clamping member 24 may be fixed to thesupport portion 22 and may be provided to be movable (slidable on thesupport surface 27a) in the facing direction of the first clampingmember 24 and the second clamping member 26 (hereinafter, simply referred to as the "facing direction"). - A part of the

Thesecond clamping member 26 is biased toward the first clampingmember 24 by a biasing member (not illustrated) such as a spring. That is, the end surfaces of thesecond clamping member 26 and the first clampingmember 24 are in contact with each other by a biasing force of a biasing member in a state in which a force other than the biasing member is not applied to thesecond clamping member 26. - The
second clamping member 26 moves in synchronization with the movement of thesupport portion 22. Thesecond clamping member 26 moves in a direction moving away from the first clampingmember 24 by the movement of thesupport portion 22 from the second position P2 (seeFIG. 6B ) to the first position P1 (seeFIG. 6A ). Specifically, thesecond clamping member 26 can be pressed down in a direction opposite to the biasing direction of the biasing member by a cam mechanism (not illustrated) or the like when thesupport portion 22 moves from the second position P2 to the first position P1. Accordingly, a gap (space) is formed between the first clampingmember 24 and thesecond clamping member 26 in the clampingportion 23. Furthermore, the movement of thesecond clamping member 26 may not be synchronized with the movement of thesupport portion 22. - As illustrated in

That is, thefirst clamping mechanism 20 moves between the first position P1 and the second position P2. Thesupport portion 32 moves by the driving of, for example, a driving portion (not illustrated) such as a cylinder. The driving portion may be the same as the driving portion that drives thesupport portion 22 or may be separately provided. In the embodiment, as described above, one end portion of the longitudinal direction provided with theshaft 31 in thesupport portion 32 will be referred to as a base end portion and the other end portion of the longitudinal direction opposite to the one end portion will be referred to as a front end portion. - The
support portion 32 is provided with aconcave portion 35. Theconcave portion 35 is provided at the side of the front end portion of thesupport portion 32. Theconcave portion 35 opens to themain surface 32a and the pair of side surfaces 32c and 32d of thesupport portion 32. Theconcave portion 35 exposes a part of the clampingportion 33.

FIG. 2 , the clampingportion 33 includes the first clampingmember 34 and thesecond clamping member 36. Each of the first clampingmember 34 and thesecond clamping member 36 is formed in a columnar shape. Each of the first clampingmember 34 and thesecond clamping member 36 is formed of, for example, metal such as SUS having abrasion resistance. The diameter of each of the first clampingmember 34 and thesecond clamping member 36 may be appropriately set. - The
first clamping member 34 and thesecond clamping member 36 are disposed at thesupport portion 32 so that respective end surfaces face each other. Specifically, the first clampingmember 34 is disposed at the side of the front end portion of thesupport portion 32 and thesecond clamping member 36 is disposed at the side of the base end portion of thesupport portion 32 in relation to the first clampingmember 34. Thesecond clamping mechanism 30 holds a yarn by clamping the yarn between the end surface of the first clampingmember 34 and the end surface of thesecond clamping member 36 in the clampingportion 33. - A part of the first clamping
member 34 is accommodated in thesupport portion 32 and a part of the first clampingmember 34 is exposed in theconcave portion 35 of thesupport portion 32. Thefirst clamping member 34 may be fixed to thesupport portion 32 and may be provided to be movable in the facing direction of the first clampingmember 34 and the second clamping member 36 (to be slidable on thesupport surface 37a). - A part of the
second clamping member 36 is accommodated in thesupport portion 32 and a part of thesecond clamping member 36 is exposed in theconcave portion 35 of thesupport portion 32. Thesecond clamping member 36 is movably provided in thesupport portion 32. Thesecond clamping member 36 moves in the facing direction. Thesecond clamping member 36 is biased toward the first clampingmember 34 by a biasing member (not illustrated) such as a spring. That is, the end surfaces of thesecond clamping member 36 and the first clampingmember 34 contact each other by a biasing force of a biasing member in a state in which a force other than the biasing member is not applied to thesecond clamping member 36. - The
second clamping member 36 moves in synchronization with the movement of thesupport portion 32. Thesecond clamping member 36 moves in a direction moving away from the first clampingmember 34 by the movement of thesupport portion 32 from a second position P2 (seeFIG. 6B ) to a first position P1 (seeFIG. 6A ). Specifically, thesecond clamping member 36 is pressed down in a direction opposite to the biasing direction of the biasing member by a cam mechanism (not illustrated) or the like when thesupport portion 32 moves from the second position P2 to the first position P1. Accordingly, a gap (space) is formed between the first clampingmember 34 and thesecond clamping member 36 in the clampingportion 33. Furthermore, the movement of thesecond clamping member 36 may not be synchronized with the movement of thesupport portion 32. - Subsequently, a method of forming an entangled portion using the synthetic yarn splicer 1 (a splicing method) will be described.
- First, as illustrated in
FIG. 6A , the first yarn Y1 and the second yarn Y2 are set on thesynthetic yarn splicer 1. Specifically, the first yarn Y1 and the second yarn Y2 are located in thechamber 14 through theslit 13 of theyarn splicing portion 10 and are disposed on thefirst clamping mechanism 20 and thesecond clamping mechanism 30 located at the first position P1. More specifically, the first yarn Y1 and the second yarn Y2 are disposed between the first clampingmember 24 and thesecond clamping member 26 of thefirst clamping mechanism 20 and are disposed between the first clampingmember 34 and thesecond clamping member 36 of thesecond clamping mechanism 30. Accordingly, the first yarn Y1 and the second yarn Y2 are placed on thefirst contact surface 27b and thesecond contact surface 27c of thefirst clamping mechanism 20 and are placed on thefirst contact surface 37b and thesecond contact surface 37c of thesecond clamping mechanism 30. - When the first yarn Y1 and the second yarn Y2 are set on the
synthetic yarn splicer 1, theoperation portion 7 is operated (pressed down). Accordingly, in thesynthetic yarn splicer 1, the driving portion is operated so that thefirst clamping mechanism 20 and thesecond clamping mechanism 30 are operated. - Specifically, the first yarn Y1 and the second yarn Y2 are clamped by the first clamping
member 24 and thesecond clamping member 26 of thefirst clamping mechanism 20. Further, the first yarn Y1 and the second yarn Y2 are clamped by the first clampingmember 34 and thesecond clamping member 36 of thesecond clamping mechanism 30. Then, as illustrated inFIG. 6B , thefirst clamping mechanism 20 and thesecond clamping mechanism 30 move from the first position P1 to the second position P2. Accordingly, as illustrated inFIG. 7 , the first yarn Y1 and the second yarn Y2 are held between the clampingportion 23 and the clampingportion 33 in a loosened state. Further, the first yarn Y1 and the second yarn Y2 are held while contacting at least thesecond contact surface 27c and thesecond contact surface 37c. - Further, when the
operation portion 7 is operated, air is injected from theinjection hole 16a to thechamber 14 through theair flow path 16. Accordingly, the first yarn Y1 and the second yarn Y2 located inside thechamber 14 are spliced by the action of air to form an entangled portion. - Subsequently, the operation of the
operation portion 7 is cancelled. Accordingly, in thesynthetic yarn splicer 1, the injection of air from theinjection hole 16a to thechamber 14 is stopped and thefirst clamping mechanism 20 and thesecond clamping mechanism 30 are operated. - Specifically, as illustrated in
FIG 6A , thefirst clamping mechanism 20 and thesecond clamping mechanism 30 move from the second position P2 to the first position P1. In accordance with this operation, thesecond clamping member 26 of thefirst clamping mechanism 20 moves in a direction moving away from the first clampingmember 24 and the clamping of the first yarn Y1 and the second yarn Y2 by the first clampingmember 24 and thesecond clamping member 26 is cancelled. Also similarly to thesecond clamping mechanism 30, thesecond clamping member 36 moves in a direction moving away from the first clampingmember 34 and the clamping of the first yarn Y1 and the second yarn Y2 by the first clampingmember 34 and thesecond clamping member 36 is cancelled. Furthermore, the clamping of the first yarn Y1 and the second yarn Y2 by the first clampingmember 24 and thesecond clamping member 26 may be cancelled after thefirst clamping mechanism 20 moves from the second position P2 to the first position P1. Similarly, the clamping of the first yarn Y1 and the second yarn Y2 by the first clampingmember 34 and thesecond clamping member 36 may be cancelled after thesecond clamping mechanism 30 moves from the second position P2 to the first position P1. With the above-described configuration, the splicing of the first yarn Y1 and the second yarn Y2 by thesynthetic yarn splicer 1 is completed. Accordingly, the first yarn Y1 and the second yarn Y2 become one yarn. - Subsequently, an operation and an effect of the
synthetic yarn splicer 1 according to the embodiment will be described. - In the
synthetic yarn splicer 1, when the first yarn Y1 and the second yarn Y2 are swayed in thechamber 14 by using the clampingportions chamber 14 is smaller than φ4.0 mm, the yarns easily contact the innerperipheral surface 14a of thechamber 14. In this way, when a ratio in which the first yarn Y1 and the second yarn Y2 contact the innerperipheral surface 14a of thechamber 14 increases, an influence of a friction due to a contact becomes noticeable. Accordingly, there is concern that an entangled portion is not appropriately formed since the first yarn Y1 and the second yarn Y2 are damaged. Further, in the synthetic yarn splicer, since air hardly acts on the first yarn Y1 and the second yarn Y2 inside thechamber 14 when the diameter R1 of thechamber 14 becomes larger than φ7.0 mm, an entangled portion is not appropriately formed. As a result, there is a possibility that the tensile elongation of the entangled portion decreases. - In contrast, in the
synthetic yarn splicer 1 according to the embodiment, the diameter R1 of thechamber 14 is equal to or larger than φ4.0 mm and equal to or smaller than φ7.0 mm. Accordingly, in the synthetic yarn splicer, it is possible to suppress an influence due to the contact with the innerperipheral surface 14a of thechamber 14 and to appropriately apply air to the first yarn Y1 and the second yarn Y2 when the first yarn Y1 and the second yarn Y2 are swayed inside thechamber 14. Thus, in thesynthetic yarn splicer 1, the entangled portion can be appropriately formed. As a result, in thesynthetic yarn splicer 1, it is possible to suppress a change in tensile elongation decrease amount while suppressing a decrease in tensile elongation of the entangled portion. -
FIGS. 7A and 7B show a tensile elongation measurement result of an entangled portion when the entangled portion is formed by changing a combination of the diameter R1 of thechamber 14 and the diameter R2 of theinjection hole 16a in thesynthetic yarn splicer 1 according to the embodiment. In the measurement, TENSORAPID4 (trade name) manufactured by USTER was used.FIG. 7A shows a result when the pressure of air injected from theinjection hole 16a is set to 4 kgf/cm2.FIG. 7B shows a result when the pressure of air injected from theinjection hole 16a is set to 5 kgf/cm2. The yarn is a pre-oriented yarn (POY). The yarn corresponding to a measurement object is 88dtex-72f. The tensile elongation of the yarn without the entangled portion used for the measurement ofFIG. 7A was 132.3 (%). The tensile elongation of the yarn without the entangled portion used for the measurement ofFIG. 7B was 131.1 (%). - As shown in
FIGS. 7A and 7B , a result was obtained such that the tensile elongation decrease amount was relatively small when the diameter R2 of theinjection hole 16a was equal to or larger than φ0.8 mm and equal to or smaller than 2.0 mm and the diameter R1 of thechamber 14 was equal to or larger than φ4.0 mm and equal to or smaller than 7.0 mm. As shown inFIG. 7A , a result was obtained such that the tensile elongation decrease amount was relatively small when the air pressure was 4 kgf/cm2, particularly, when the diameter R1 of thechamber 14 was φ5.5 mm, φ6.0 mm, and φ7.0 mm. As shown inFIG. 7B , a result was obtained such that the tensile elongation decrease amount was relatively small when the air pressure was 5 kgf/cm2, particularly, when the diameter R1 of thechamber 14 is φ6.0 mm and φ7.0 mm. As described above, in thesynthetic yarn splicer 1, it was found that a decrease in tensile elongation of the entangled portion could be suppressed when the diameter R1 of thechamber 14 was set to be equal to or larger than φ4.0 mm and equal to or smaller than φ7.0 mm. - Subsequently, an effect of the
synthetic yarn splicer 1 will be described on the basis of Examples and Comparative Examples.FIGS. 8A and 8B show a tensile elongation decrease amount (%) from a reference value in Examples and Comparative Examples when the tensile elongation measurement value of the synthetic fiber without the entangled portion is used as the reference value. In the measurement, TENSORAPID4 (trade name) manufactured by USTER was used. Examples show a result of the yarn provided with the entangled portion when the diameter R1 of thechamber 14 is set to φ6.0 mm in thesynthetic yarn splicer 1 according to the embodiment. Comparative Examples show a result of the yarn provided with the entangled portion when the diameter R1 of thechamber 14 is set to φ3.5 mm. The yarn is a pre-oriented yarn. The yarn corresponding to a measurement object is 88dtex-48f-CD (cationic dyeable yarn). The pressure of the air injected from theinjection hole 16a was set to 3.5 kgf/cm2. "A", "B", "C", and "D" show a repeated test result in the same condition. - In Example 1 and Comparative Example 1, the diameter R2 of the
injection hole 16a was set to φ1.3 mm. In Example 1, the tensile elongation decrease amount [%] from the reference value was -3.5% in "A", -2.1% in "B", -2.3% in "C", and -0.7% in "D". In Example 1, a difference between a minimum value and a maximum value of a decrease amount was 2.8%. - In Comparative Example 1, the tensile elongation decrease amount [%] from the reference value was -7.6% in "A", -5.3% in "B", -14.9% in "C", and -12.8% in "D". In Comparative Example 1, a difference between a minimum value and a maximum value of a decrease amount was 9.6%.
- In Example 2 and Comparative Example 2, the diameter R2 of the
injection hole 16a was set to φ1.6 mm. In Example 2, the tensile elongation decrease amount [%] from the reference value was -8.5% in "A", -12.4% in "B", -12.3% in "C", and -8.8% in "D". In Example 2, a difference between a minimum value and a maximum value of a decrease amount was 3.9%. - In Comparative Example 2, the tensile elongation decrease amount [%] from the reference value was -10.5% in "A", -8.4% in "B", -16.6% in "C", and -9.6% in "D". In Comparative Example 2, a difference between a minimum value and a maximum value of a decrease amount was 8.2%.
- As described above, when the diameter R1 of the
chamber 14 is set to φ6.0 mm, there is a tendency that the tensile elongation decrease amount is small as compared with the case of φ3.5 mm. Further, in Examples 1 and 2, a difference between a minimum value and a maximum value of a decrease amount of "A" to "D" is smaller than that of Comparative Examples 1 and 2. For that reason, it was found that a change in tensile elongation decrease amount was small in thesynthetic yarn splicer 1. Thus, since it is possible to stably form the entangled portion in thesynthetic yarn splicer 1, it was found that a change in tensile elongation decrease amount could be suppressed while suppressing a decrease in tensile elongation of the entangled portion. - In the
synthetic yarn splicer 1 according to the embodiment, theinjection hole 16a of theyarn splicing portion 10 has a circular shape. The diameter R2 of theinjection hole 16a is equal to or larger than φ0.8 mm and equal to or smaller than φ2.0 mm. In this configuration, as shown inFIGS. 7A and 7B , it is possible to suppress a change in tensile elongation decrease amount while suppressing a decrease in tensile elongation of the entangled portion. - Although the embodiment of the invention has been described, the invention is not essentially limited to the above-described embodiment and can be modified into various forms without departing from the gist thereof.

FIG. 1 has been described as the shape of themain body 3. However, the shape of themain body 3 is not limited to the shape illustrated inFIG. 1 . - In the above-described embodiment, an example of an embodiment in which the

That is, long and short axes of theoval chamber 14 may be equal to or larger than 4.0 mm and equal to or smaller than 7.0 mm. - In the above-described embodiment, an example of an embodiment in which the first yarn Y1 and the second yarn Y2 are disposed on the
first clamping mechanism 20 and thesecond clamping mechanism 30 located at the first position P1, thefirst clamping mechanism 20 and thesecond clamping mechanism 30 are moved from the first position P1 to the second position P2, and air is injected from theinjection hole 16a to thechamber 14 to form an entangled portion has been described. However, a method of forming the entangled portion by using thesynthetic yarn splicer 1 is not limited thereto. - For example, the first yarn Y1 and the second yarn Y2 are disposed on the
