Japanese Unexamined Patent Publication No. 6-41821

In a conventional air spinning device, a swirling air flow is generated by supplying compressed air from a nozzle block in the vicinity of the tip of the hollow guide shaft. The tip of the hollow guide shaft may be worn by friction (contact) with fibers swirling by compressed air. In a conventional air spinning device, compressed air is blown to a specific part of the hollow guide shaft body. Therefore, friction between the swirling fiber and the hollow guide shaft body may also occur at a specific location, so that wear may proceed at a specific location of the hollow guide shaft body.

One aspect of the present invention is to provide an air spinning device and a spinning machine capable of suppressing the progress of wear of a hollow guide shaft body.

The air spinning apparatus according to one aspect of the present invention has a spinning chamber in which fiber bundles are swirled by a swirling flow of air, and a nozzle having a first nozzle through which air injected into the spinning chamber is passed to generate the swirling flow. A block, a hollow guide shaft body having a passage for guiding the fiber bundle swirled in the spinning chamber to the outside, a spinning position where the hollow guide shaft body is located in the spinning chamber, and a position farther from the spinning chamber than the spinning position. The hollow guide shaft body is provided with a moving portion for moving the hollow guide shaft body, and the hollow guide shaft body is rotated by a predetermined angle around the axis by the operation of moving the hollow guide shaft body between the spinning position and the separated position.

In the air spinning apparatus according to one aspect of the present invention, the hollow guide shaft body is rotated by the operation of moving the hollow guide shaft body between the spinning position and the separated position by the moving portion. As a result, in the air spinning device, the portion of the hollow guide shaft body to which the air injected from the first nozzle of the nozzle block is blown changes. Therefore, since it is possible to prevent the air from being continuously injected into a specific portion of the hollow guide shaft body, it is possible to suppress the occurrence of friction between the swirling fiber and the specific portion of the hollow guide shaft body. As a result, in the air spinning device, the progress of wear of the hollow guide shaft can be suppressed.

In one embodiment, the hollow guide shaft body is connected to a guide shaft member into which a fiber bundle is introduced, a guide pipe having a passage, a support member for accommodating the guide pipe, and a guide shaft member. The guide shaft member may be provided so as to be rotatable around the axis with respect to the support member and the fixing member. The air injected from the first nozzle of the nozzle block is injected toward the guide shaft member. Therefore, by rotating the guide shaft member, it is possible to prevent the hollow guide shaft body from being continuously injected with air at a specific location.

In one embodiment, the guide shaft member may rotate by a predetermined angle around the axis by moving to a separated position. In this configuration, the guide shaft member can be rotated by the operation of interrupting the spinning operation.

In one embodiment, the guide pipe is movable with respect to the support member in the axial direction of the guide pipe, is provided so as to be rotatable around the axis together with the guide shaft member, and guides the fiber bundle. It has a first pipe portion to be introduced from the shaft member and a second pipe portion which is provided separately from the first pipe portion and discharges the fiber bundle to the outside, and the support member is a separated position of the hollow guide shaft body. It has a cam that rotates the first pipe part around the axis by moving to, and has a contact part that comes into contact with the second pipe part by moving to the separated position of the hollow guide shaft body, and the first pipe part is It may be moved to the guide shaft member side by the second pipe portion in contact with the contact portion, and may be rotated about the shaft by the cam when it reaches a predetermined position. In this configuration, the first pipe portion is rotated by the cam by moving the hollow guide shaft body to the separated position. As a result, the guide shaft member connected to the first pipe portion can be rotated by a predetermined angle around the axis by moving to the separated position.

In one embodiment, a spring that urges the first pipe portion toward the second pipe portion may be provided. In this configuration, when the hollow guide shaft body moves to the spinning position side, the first pipe portion is pushed back from the predetermined position to the original position by the spring. As a result, the first pipe portion (guide shaft member) can be rotated only when moving to the separated position.

In one embodiment, the guide shaft member may rotate by a predetermined angle around the axis by moving from the spinning position to the separating position and moving from the separating position to the spinning position. In this configuration, the guide shaft member rotates due to both the movement from the spinning position to the separation position and the movement from the separation position to the spinning position. Therefore, the guide shaft member can be rotated frequently. Therefore, the progress of wear of the hollow guide shaft can be further suppressed.

In one embodiment, the guide shaft member is provided with a first concave-convex portion continuously provided in the circumferential direction at a position facing the support member and a first concave-convex portion continuously provided in the circumferential direction at a position facing the fixing member. It has two uneven portions, the support member is provided at a position facing the first uneven portion, and has a third uneven portion that engages with and separates from the first uneven portion, and the fixing member has a second uneven portion. It is provided at a position facing the concavo-convex portion, and has a fourth concavo-convex portion that engages with and separates from the second concavo-convex portion. The concavo-convex portion engages, the second concavo-convex portion and the fourth concavo-convex portion are separated from each other, and the second concavo-convex portion and the fourth concavo-convex portion engage with each other due to the movement of the spinning position and the separated position to the other position. At the same time, the first concavo-convex portion and the third concavo-convex portion are separated from each other, and at one position, the second concavo-convex portion and the fourth concavo-convex portion do not mesh with each other. The uneven portion and the third uneven portion may have a positional relationship in which they do not mesh with each other. In this configuration, the pitch of the unevenness is deviated between the third uneven portion and the fourth uneven portion. Therefore, there is a transition from a state in which the first concavo-convex portion and the third concavo-convex portion are engaged at one of the spinning position and the separated position to a state in which the second concavo-convex portion and the fourth concavo-convex portion are engaged at the other position. By doing so, the guide shaft member rotates. As a result, the guide shaft member can be rotated by both the movement from the spinning position to the separation position and the movement from the separation position to the spinning position.

In one embodiment, the first spring that urges the first uneven portion and the third uneven portion in the direction in which they are close to each other, and the second spring that urges the second uneven portion and the fourth uneven portion in the direction in which they are close to each other. And may be provided. In this configuration, the first concavo-convex portion and the third concavo-convex portion can be reliably engaged by moving to one of the spinning position and the separated position, and the second concavo-convex portion and the second concavo-convex portion can be moved to the other position. It is possible to securely engage with the fourth uneven portion.

In one embodiment, the guide pipe may be provided with a second nozzle through which the air injected into the passage passes. In this configuration, at the start of the spinning operation, air is injected from the first nozzle into the nozzle block and air is injected from the second nozzle into the guide pipe, so that the fiber bundle is falsely twisted and the fibers are twisted. The bundle can be reliably pulled into the air spinning device.

In one embodiment, the predetermined angle may be an angle that is not divisible by 360 degrees. In this configuration, even when the hollow guide shaft body makes one rotation, the hollow guide shaft body is not located at the same position with respect to the injection position of the first nozzle. Therefore, the portion of the hollow guide shaft body to which the air injected from the first nozzle is blown can be dispersed. Therefore, the progress of wear of the hollow guide shaft can be further suppressed.

In one embodiment, the moving unit may move the hollow guide shaft to a separate position when the spinning operation is interrupted. In this configuration, the hollow guide shaft can be rotated each time the spinning operation is interrupted.

The spinning machine according to one aspect of the present invention includes the above-mentioned air spinning device and a winding device for winding the yarn produced by the air spinning device into a package.

The spinning machine according to one aspect of the present invention includes the above-mentioned air spinning apparatus. Therefore, in the spinning machine, the progress of wear of the hollow guide shaft body can be suppressed in the air spinning device. Further, in the spinning machine, a plurality of air spinning devices may be provided. In such a configuration, it takes a lot of labor to manually rotate the hollow guide shaft of the air spinning apparatus. Regarding this, in the spinning machine according to one aspect of the present invention, since the hollow guide shaft body rotates automatically, the work of rotating the hollow guide shaft body can be reduced.

According to one aspect of the present invention, the progress of wear of the hollow guide shaft can be suppressed.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the description of the drawings, the same or equivalent elements are designated by the same reference numerals, and duplicate description will be omitted. Further, hereinafter, "upstream" and "downstream" mean upstream and downstream in the traveling direction of the fiber bundle F and the yarn Y at the time of spinning.

As shown in FIG. 1, the spinning machine 1 includes a plurality of spinning units 2, a thread joint carriage 3, a ball lifting carriage (not shown), a first end frame 4, and a second end frame 5. Be prepared. The plurality of spinning units 2 are arranged in a row. Each spinning unit 2 produces a yarn Y and winds it around a package P. When the yarn Y is cut by a certain spinning unit 2 or the yarn Y is cut by some reason, the yarn splicing carriage 3 performs a yarn splicing operation by the spinning unit 2. When the package P is fully wound in a certain spinning unit 2, the ball lifting trolley lifts the package P and supplies a new bobbin B to the spinning unit 2.

The first end frame 4 houses a recovery device or the like that collects fiber waste, yarn waste, and the like generated in the spinning unit 2. The second end frame 5 supplies power to each part of the spinning unit 2 and the air supply part that adjusts the air pressure of the compressed air (air) supplied to the spinning machine 1 to supply air to each part of the spinning machine 1. A drive motor or the like for the operation is housed. The second end frame 5 is provided with a machine base control device 5a, a display screen 5b, and an input key 5c. The machine stand control device 5a centrally manages and controls each part of the spinning machine 1. The display screen 5b can display information on the setting contents and / or the state of the spinning unit 2. The setting work of the spinning unit 2 can be performed by the operator performing an appropriate operation using the input key 5c.

As shown in FIG. 2, each spinning unit 2 has a draft device 6, an air spinning device 7, a thread monitoring device 8, a tension sensor 9, and a thread storage device in this order from the upstream side in the traveling direction of the thread Y. An eleven, a waxing device 12, and a winding device 13 are provided. The unit controller 10 is provided for each of a predetermined number of spinning units 2 and controls the operation of the spinning units 2.

The draft device 6 drafts the sliver (fiber bundle) S. The draft device 6 is supplied with the sliver S from Kens (not shown) via the creel 14. The creel 14 is installed in a creel device (not shown). As shown in FIG. 3, the creel 14 has a main body 14a, a shaft 14b, and a cam 14c.

The main body 14a has a cylindrical shape. The main body 14a is rotatably provided by the shaft 14b. The outer peripheral surface of the main body 14a has a concave shape in the width direction of the main body 14a. The outer peripheral surface of the main body 14a guides the sliver S. A locking portion 14d is provided on the inner peripheral surface of the main body 14a. The locking portion 14d projects inward from the inner peripheral surface of the main body 14a. A plurality of locking portions 14d (three in the present embodiment) are arranged at predetermined intervals in the circumferential direction. Covers 14h are provided on both sides of the main body 14a. The end of the shaft 14b is inserted into the cover 14h. As a result, the main body 14a rotates about the shaft 14b.

The shaft 14b is a rod-shaped member. The shaft 14b is provided coaxially with the rotation shaft of the main body 14a. The shaft 14b has a portion having a circular cross section and a portion having a quadrangular cross section. Specifically, as shown in FIG. 3, the cross sections of both ends of the shaft 14b in the longitudinal direction have a circular shape. The cross section of the central portion of the shaft 14b in the longitudinal direction has a quadrangular shape. The end of the shaft 14b is inserted into the cover 14h and projects outward from the cover 14h. The shaft 14b is supported by a support portion (not shown).

The cam 14c is, for example, a plate member. The cam 14c is supported at the center of the shaft 14b. The cam 14c is provided so as to be movable in the vertical direction with respect to the shaft 14b. Specifically, the cam 14c is provided with an insertion hole 14e into which the shaft 14b is inserted. The insertion hole 14e is provided so as to penetrate in the thickness direction of the cam 14c. The insertion hole 14e has a rectangular shape. The width dimension of the insertion hole 14e is equivalent to the width dimension of the shaft 14b, and the height dimension of the insertion hole 14e is larger than the height dimension of the shaft 14b. As a result, the cam 14c can move in the vertical direction with respect to the shaft 14b. The tip of the cam 14c (the end opposite to the end supported by the shaft 14b) abuts on the inner peripheral surface of the shaft 14b at the lowest position of the cam 14c.

The tip of the cam 14c is composed of a first surface 14f and a second surface 14g. The first surface 14f is a surface along the extending direction (vertical direction) of the cam 14c. The second surface 14g is a surface that is inclined with respect to the extending direction (vertical direction) of the cam 14c. The second surface 14g is inclined in a direction away from the first surface 14f toward the shaft 14b side from the top (tip of the cam 14c) where the second surface 14g and the first surface 14f intersect.

Subsequently, the operation of the creel 14 will be described. When the sliver S is hung on the creel 14 and the sliver S is supplied to the draft device 6, the main body 14a rotates as shown in FIG. 4A. When the locking portion 14d moves while one end of the locking portion 14d of the main body 14a is in contact with the second surface 14g of the cam 14c, the cam 14c is pushed upward by the locking portion 14d. When the cam 14c slides on the locking portion 14d and reaches the other end of the locking portion 14d, the cam 14c moves downward and the inner circumference of the main body 14a is as shown in FIG. 4 (b). Contact the surface. At this time, since the locking portion 14d is locked by the first surface 14f of the cam 14c, the rotation of the main body 14a in the counterclockwise direction is restricted. As described above, in the creel 14, only rotation in one direction is permitted, and rotation in the other direction is restricted. As a result, it is possible to prevent the creel 14 from rotating in the direction opposite to the supply direction of the sliver S due to the weight of the sliver S or the like. As a result, it is possible to prevent the sliver S from being stretched before being supplied to the draft device 6.

As shown in FIG. 2, the air spinning device 7 twists the fiber bundle F drafted by the draft device 6 by a swirling air flow (swirl flow of air) to generate a yarn Y. The yarn storage device 11 takes the slack of the yarn Y between the air spinning device 7 and the take-up device 13. The waxing device 12 applies wax to the yarn Y between the yarn storage device 11 and the take-up device 13. The take-up device 13 winds the thread Y on the bobbin B to form the package P.

The yarn monitoring device 8 monitors information on the running yarn Y between the air spinning device 7 and the yarn storage device 11, and detects the presence or absence of yarn defects based on the monitored information. When the thread monitoring device 8 detects a thread defect, the thread monitoring device 8 transmits a thread defect detection signal to the unit controller 10. The tension sensor 9 measures the tension of the traveling yarn Y between the air spinning device 7 and the yarn storage device 11, and transmits a tension measurement signal to the unit controller 10. When the unit controller 10 determines that there is an abnormality based on the detection result of the yarn monitoring device 8 and / or the tension sensor 9, the yarn Y is cut in the spinning unit 2.

The thread splicing carriage 3 has a thread splicing device 15, a suction pipe 16, and a suction mouse 17. The suction pipe 16 is rotatably supported by a support shaft 16a, captures the yarn Y from the air spinning apparatus 7, and guides the yarn Y to the yarn splicing apparatus 15. The suction mouse 17 is rotatably supported by a support shaft 17a, captures the thread Y from the winding device 13, and guides the thread Y to the thread joining device 15. The thread splicing device 15 splices the guided threads Y together. The yarn splicing device 15 is a splicer using compressed air, a knotter for mechanically splicing yarn Y, or the like. The yarn splicing device 15 does not splice the yarns Y with each other, but may be a piecer for splicing the yarn Y and the fiber bundle F together.

Subsequently, the air spinning apparatus 7 will be described in detail.

The end opposite to the tip) is supported by the support shaft 67.

The first spring 63 connects the first support portion 61 and the second support portion 62. The first spring 63 is urged in a direction in which the first support portion 61 and the second support portion 62 are close to each other. The cylinder 65 moves the second support portion 62. Specifically, the cylinder 65 is moved in the direction in which the second support portion 62 is separated from the first support portion 61, that is, in the direction in which the hollow guide shaft body 30 is separated from the nozzle block 20.

The second spring 64 connects the second support portion 62 and the frame of the spinning unit 2. The second spring 64 is in a direction opposite to the direction in which the second support portion 62 (hollow guide shaft body 30) is rotated by the cylinder 65 (direction away from the first support portion 61) (in the first support portion 61). Bounce in the approaching direction).

The contact portion 66 is a member with which the hollow guide shaft body 30 comes into contact. The contact portion 66 is arranged on the downstream side of the air spinning device 7 in the traveling direction of the yarn Y. As shown in FIG. 8, the contact portion 66 comes into contact with the second pipe portion 41 of the guide pipe 32 of the hollow guide shaft body 30 at a separated position of the air spinning device 7 described later. The contact portion 66 is fixed to the support shaft 67.

The air spinning device 7 can be moved to a spinning position and a separated position. As shown in FIG. 7, the spinning position is an air spinning device when the air spinning device 7 is arranged close to the draft device 6 at the time of spinning and the fiber bundle F is supplied from the draft device 6 to the air spinning device 7. It is the position of 7. As shown in FIG. 8, the separation position is a position farther from the draft device 6 than the spinning position. The separation position is the position when the spinning operation is interrupted. The hollow guide shaft body 30 can be further moved from the nozzle block 20 at a separated position. When the air spinning device 7 moves from the spinning position to the separated position, the nozzle block 20 and the hollow guide shaft body 30 are integrally separated from the draft device 6. After that, as shown in FIG. 8, only the nozzle block 20 stops at a predetermined position. The hollow guide shaft body 30 continues to move away from the nozzle block 20. After that, the hollow guide shaft body 30 separated from the nozzle block 20 comes into contact with the contact portion 66 and stops.

Subsequently, the operation of the air spinning device 7 will be described. As shown in FIG. 7, when the air spinning device 7 is located at the spinning position, the guide shaft member 31 and the guide pipe 32 of the hollow guide shaft body 30 are separated from the nozzle block 20 by the spring 58. ) Is being urged. At this time, as shown in FIG. 9, the protrusion 48 of the rotating member 47 is separated from the cam 46 of the second pipe portion 41 and is formed in the groove 56a formed by the outer cam 56 of the first support portion 51. positioned.

When the hollow guide shaft body 30 moves toward the separated position due to the interruption of the spinning operation and the hollow guide shaft body 30 is positioned (reached) at the separated position, the second portion 41b of the second pipe portion 41 of the guide pipe 32 is hit. It abuts on the contact portion 66. When the second pipe portion 41 comes into contact with the contact portion 66, as shown in FIG. 10, the second pipe portion 41 is pushed toward the nozzle block 20 side, and the spring 58 contracts. As a result, the guide shaft member 31 and the guide pipe 32 move to the upstream side. At this time, the cam surface 46a of the cam 46 provided in the first portion 41a of the second pipe portion 41 and the end surface 48a of the protrusion 48 of the rotating member 47 engage with each other, and the rotating member 47 is moved upstream by the second pipe portion 41. Move to the side. When the end surface 48a of the rotating member 47 reaches the upper end (predetermined position) of the end surface 56b of the outer cam 56 of the first support portion 51, the end surface 48a of the protrusion 48 of the rotating member 47 becomes the end surface of the outer cam 56 of the first support portion 51. Slide along 56b. As a result, the rotating member 47 rotates (rotates counterclockwise in this embodiment), and the first pipe portion 40 and the guide shaft member 31 of the guide pipe 32 rotate accordingly. After that, when the air spinning device 7 returns to the spinning position, the protrusion of the rotating member 47 is located in the groove 56a formed by the outer cam 56 of the first support portion 51. As described above, in the air spinning device 7, the guide shaft member 31 rotates about the axis by the operation of moving between the spinning position and the separated position.

The rotation angle of the guide shaft member 31 is set by designing the shapes of the cam 46 of the second pipe portion 41, the protrusion 48 of the rotating member 47, and the outer cam 56 of the first support portion 51. The rotation angle of the guide shaft member 31 by one operation is preferably an angle that is not divisible by 360 degrees (for example, 7 degrees, 11 degrees, etc.).

As described above, in the air spinning apparatus 7 according to the present embodiment, the hollow guide shaft body 30 rotates due to the operation of the hollow guide shaft body 30 moving between the spinning position and the separated position. In the present embodiment, the hollow guide shaft body 30 moves from the spinning position to the separated position and rotates by being positioned at the separated position. As a result, in the air spinning device 7, the portion of the hollow guide shaft body 30 to which the air injected from the first nozzle 24 of the nozzle block 20 is blown changes. Therefore, since it is possible to prevent the hollow guide shaft body 30 from continuously injecting air into a specific portion, it is possible to suppress the occurrence of friction between the swirling fiber bundle F and the specific portion of the hollow guide shaft body 30. As a result, in the air spinning device 7, the progress of wear of the hollow guide shaft body 30 can be suppressed.

In the air spinning apparatus 7 according to the present embodiment, the guide pipe 32 is provided so as to be rotatable around the axis together with the guide shaft member 31, and the fiber bundle F is introduced from the guide shaft member 31.

The support member 33 has an outer cam 56 that rotates the first pipe portion 40 about an axis by moving the hollow guide shaft body 30 to a separated position. Further, the air spinning device 7 includes a contact portion 66 that comes into contact with the second pipe portion 41 by moving the hollow guide shaft body 30 to a separated position. In the air spinning device 7, the first pipe portion 40 is moved toward the guide shaft member 31 by the second pipe portion 41 that abuts on the contact portion 66, and when it reaches a predetermined position, it is rotated about the axis by the outer cam 56. Be made to. In this configuration, the first pipe portion 40 is rotated by the outer cam 56 by moving the hollow guide shaft body 30 to the separated position. As a result, the guide shaft member 31 connected to the first pipe portion 40 can be rotated by a predetermined angle around the axis by moving to the separated position.

In the air spinning apparatus 7 according to the present embodiment, the predetermined angle is an angle that is not divisible by 360 degrees. In this configuration, the hollow guide shaft body 30 is not located at the same position as the injection position of the first nozzle 24 even when the hollow guide shaft body 30 makes one rotation. Therefore, the portion of the hollow guide shaft body 30 to which the air injected from the first nozzle 24 is blown can be dispersed. Therefore, the progress of wear of the hollow guide shaft 30 can be further suppressed.

In the air spinning apparatus 7 according to the present embodiment, the cylinder 65 moves the hollow guide shaft body 30 to a separated position when the spinning operation is interrupted. In this configuration, the hollow guide shaft body 30 can be rotated each time the spinning operation is interrupted.

In the air spinning apparatus 7 according to the present embodiment, the guide pipe 32 of the hollow guide shaft body 30 is provided with a second nozzle 44 through which the air injected into the first yarn passage 42 passes. In this configuration, at the start of the spinning operation, air is injected from the first nozzle 24 into the nozzle block 20 and air is injected from the second nozzle 44 into the guide pipe 32 to apply false twist to the sliver S. While hanging, the sliver S can be reliably pulled into the air spinning apparatus 7.

In the above embodiment, the mode in which the guide shaft member 31 rotates when the hollow guide shaft body 30 moves to the separated position, that is, when the movement to the separated position is completed has been described as an example. However, the guide shaft member 31 may rotate by moving to the separated position. Specifically, the guide shaft member 31 may be in a form in which the hollow guide shaft body 30 starts moving from the spinning position toward the separation position and rotates until the hollow guide shaft body 30 reaches the separation position.

As a result, in the air spinning device 7A, the portion of the hollow guide shaft body 70 to which the air injected from the first nozzle 24 of the nozzle block 20 is blown changes. Therefore, since it is possible to prevent the hollow guide shaft body 70 from being continuously injected with air at a specific portion, it is possible to suppress the occurrence of friction between the swirling fiber bundle F and the specific portion of the hollow guide shaft body 70. As a result, in the air spinning device 7A, the progress of wear of the hollow guide shaft body 30 can be suppressed. In particular, in the air spinning apparatus 7A, the guide shaft member 71 is rotated by both the movement from the spinning position to the separation position and the movement from the separation position to the spinning position. Therefore, the guide shaft member 71 can be rotated frequently. Therefore, the progress of wear of the hollow guide shaft 70 can be further suppressed.
