Description

The present invention relates to a fiber winding device.

Conventionally, devices for winding fibers such as glass fibers have been developed, including Patent Document 1 listed below. For example, conventional fiber winding devices collect a plurality of filaments (single fibers) to form a strand, and wind the strand using a collet. The collet is attached to a turret disk, and the turret disk is rotated by a motor. Since the collet cannot wind the strand unless the turret is positioned, a mechanism for positioning the turret is required.

For example, as shown in FIG. 14, a block 202 attached to a turret board 200, a protrusion 206 fitted into a recess 204 of the block 202, and an air cylinder 208 that moves the protrusion 206 up and down are provided. After the turret board 200 is rotated by a motor, the convex portion 206 is moved toward the concave portion 204 of the stopped block 202. The alignment of the turret board 200 is completed by fitting the concave portion 204 and the convex portion 206 together.

JP2015-137222A

If the recess 204 is misaligned, the protrusion 206 will not fit into the recess 204, making it impossible to align the turret board 200. If the concave portion 204 is widened, the convex portion 206 must be made larger, and the force with which the convex portion 206 is fitted into the concave portion 204 must be increased. The air cylinder 208 becomes large, which is not preferable. If the performance of the motor is improved in order to reduce the displacement of the recess 204, the configuration for positioning becomes complicated and expensive.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a fiber winding device that can align a turret board with a simple configuration.

The fiber winding device of the present invention will be explained with reference to the drawings. Although a plurality of embodiments will be described, even in different embodiments, the same means may be given the same reference numerals and the explanation thereof may be omitted.

[Embodiment 1]
The fiber winding device 10 of the present application shown in FIG. It is provided with a collet 22 to take and a turret board 24 to which the collet 22 is attached.

The filament 12 is a single fiber, such as glass fiber or basalt fiber. Gathering shoe 14 is a roller with grooves (FIG. 2). A plurality of filaments 12 are focused in one groove. A strand 16 is formed by converging a plurality of filaments 12. A single rotating shaft 26 may be provided with a plurality of rollers, or a wide roller may be provided with a plurality of grooves. By having a plurality of grooves, a plurality of strands 16 can be formed at the same time.

The guide 18 is arranged between the gathering shoe 14 and the collet 22. Strand 16 contacts guide 18, applying tension to strand 16. The guide 18 is a roller or a comb-like plate with grooves. The guide 18 shown in FIG. 2 is a roller with grooves, and the guides 18 are provided in accordance with the number of strands 16. All guides 18 are attached to one rotating shaft 28. All guides 18 rotate simultaneously.

A traverse device 20 is provided between the guide 18 and the collet 22. The traverse device 20 includes a rotating rod 30 and a traverse 32. The traverse 32 is a curved linear body. The traverse 32 is attached to the rotating rod 30. The strand 16 is pressed against the traverse 32, and as the rotating rod 30 rotates, the strand 16 moves along the shape of the traverse 32. The strand 16 reciprocates in the direction of the rotation axis of the collet 22. When the strand 16 is wound around the collet 22, the strand 16 is wound while reciprocating in the direction of the rotation axis of the collet 22.

The collet 22 has a cylindrical or cylindrical shape (FIGS. 1 and 2). A first end 34 of the collet 22 is open, and a second end 36 of the collet 22 is disposed on the turret board 24 side. The turret disk 24 is disk-shaped, cylindrical, or cylindrical. The two collets 22 are arranged symmetrically with respect to the center of the turret disk 24. The position of one collet 22 is the winding position of the strand 16, and the position of the other collet 22 is the position of taking out the cake. A partition plate 38 is provided between the two collets 22. The collet 22 in the winding position is rotated by a motor (not shown). A rotating shaft of a motor is attached to the collet 22, and a holding part (not shown) such as a bearing that rotatably holds the rotating shaft is attached to the turret board 24. When the cake 40 is formed on one collet 22, the turret disk 24 is rotated to change the position of the collet 22, and then the other collet 22 is rotated. The number of cakes 40 formed in one collet 22 is not limited, and four cakes 40 may be formed as shown in FIG. 2.

A tube 42 is attached to the collet 22. Tube 42 rotates together with collet 22. Strand 16 is wound onto tube 42 to form cake 40. One cake 40 is formed in one tube 42. The same number of tubes 42 as the number of cakes 40 to be formed in one collet 22 are attached to the collet 22. The tube 42 is made of paper or resin.

In order to take out the cake 40 from the collet 22 at the cake 40 takeout position, a receiving member 44 and a moving device 46 for moving the receiving member 44 are provided. The receiving member 44 supports the cake 40 from below. The moving device 46 includes a servo motor, a ball screw, an air cylinder, or the like. The moving device 46 moves the receiving member 44 in the direction of the rotation axis of the collet 22. A receiving member 44 supports the cake 40 and moves the cake 40 and tube 42 together toward the first end 34. Cake 40 and tube 42 can be removed from collet 22. Note that when removing the cake 40 and tube 42 from the collet 22 manually, the receiving member 44 and the moving device 46 may be omitted.

The fiber winding device 10 includes an extrusion device 48 that moves the position of the strand 16 running between the guide 18 and the collet 22. The extrusion device 48 includes an extrusion bar 50 that pushes the strand 16 and an air cylinder that moves the extrusion bar 50 back and forth. A push bar 50 is attached to a piston rod 52 of the air cylinder. After the cake 40 is completed on the collet 22 and before the turret disk 24 rotates, the extrusion bar 50 is advanced to extrude the strands 16 to the outside of the cake 40 (FIG. 3). Strand 16 does not wrap around cake 40, but instead wraps around groove 54 near first end 34 of collet 22. When the turret disk 24 rotates, the strand 16 is re-wound from the vicinity of the first end 34 of one collet 22 to the groove 54 near the first end 34 of the other collet 22. Thereafter, the extrusion bar 50 is returned to its original position, and the strand 16 is wound around the other collet 22.

The fiber winding device 10 may include a spray device 56 that sprays a liquid such as water (FIG. 1). As the turret disk 24 rotates, the strand 16 is wound from one collet 22 to the other collet 22. At that time, one collet 22 stops rotating and the other collet 22 starts rotating, which causes the strand 16 to be pulled, transferred due to the difference in rotation of the collets 22, and broken due to the bending of the strand 16 during winding. Ru. When the strand 16 is cut, the fine filaments 12 may be scattered. Spraying liquid onto the strands 16 with a spray device 56 prevents the filaments 12 from scattering. Note that the spray device 48 is provided as necessary.

A mechanism for positioning the turret board 24 is housed in the casing 58 of FIG. 1 (FIG. 4). Further, the turret board 24 is rotated by the power of the motor 60. The positioning mechanism includes a block 62 attached to the turret board 24, a first arm 64, a second arm 66, and a power device 68.

Two blocks 62 are attached to the turret board 24. The two blocks 62 are attached at symmetrical positions with respect to the center of the turret board 24. Each block 62 is attached near the outer periphery of the turret board 24. The shape of the block 62 is not limited as long as it can be gripped by the first arm 64 and the second arm 66, such as a rectangular parallelepiped or a cube.

The first arm 64 and the second arm 66 are members for gripping the block 62. The turret board 24 is fixed by the first arm 64 and the second arm 66 gripping the block 62.

The first arm 64 includes a first rotating shaft 70 , a first gripping section 72 , a first convex section 74 , a third convex section 76 , and a connecting section 78 . The second arm 66 includes a second rotating shaft 80 , a second gripping portion 82 , a second protrusion 84 , and a fourth protrusion 86 .

The first arm 64 rotates around a first axis of rotation 70, and the second arm 66 rotates around a second axis of rotation 80. By rotating the first arm 64 and the second arm 66, the first grip part 72 and the second grip part 82 can grip the block 62 or release the block 62.

When the first arm 64 rotates, the second arm 66 rotates accordingly. The first convex portion 74, the second convex portion 84, the third convex portion 76, and the fourth convex portion 86 are used as a cooperation mechanism for the first arm 64 and the second arm 66 to rotate together. The first protrusion 74 pushes the second protrusion 84 when the first arm 64 rotates. When the first gripping part 72 and the second gripping part 82 grip the block 62, the first convex part 74 and the second convex part 84 are in contact with each other. The third protrusion 76 presses the second protrusion 84 when the first arm 64 and the second arm 66 release the block 62, causing the second arm 66 to rotate. Furthermore, when the first arm 64 and the second arm 66 grip the block 62, the third protrusion 76 pushes the fourth protrusion 86, causing the second arm 66 to rotate. The detailed operation when the first arm 64 and the second arm 66 rotate will be described later.

A connecting portion 78 of the first arm 64 is a portion connected to the power device 68. The first gripping part 72 and the connecting part 78 are arranged in opposite directions with respect to the first rotation axis 70 of the first arm 64. By moving the connecting portion 78, the first arm 64 rotates about the first rotation axis 70.

The power device 68 is an air cylinder, a hydraulic cylinder, or the like. For example, the tip of a piston rod 88 of an air cylinder is rotatably connected to the connecting portion 78. A cylinder 90 of the air cylinder is attached to a fixing plate 92 fixed to the inner surface of the housing 58. The cylinder 90 is attached to a fixed plate 92 via a belt 94. A rotating member 96 is provided between the belt 94 and the fixed plate 92, and the cylinder 90 can rotate around the rotating member 96.

Next, opening and gripping of the block 62 using the first arm 64 and the second arm 66 will be explained. First, the process of opening the block 62 will be explained.

(1) In FIG. 5, the first grip part 72 is in contact with the block 62, and the first convex part 74 is pushing the second convex part 84, so that the second grip part 82 is in contact with the block 62. The block 62 is gripped by two gripping parts 72 and 82.

(2) As the piston rod 88 enters the cylinder 90, the position of the connecting portion 78 is brought closer to the cylinder 90, and the first arm 64 rotates about the first rotation shaft 70. As shown in FIG. 6, the first arm 64 rotates in a direction in which the first gripping portion 72 moves away from the block 62. During the rotation, the third protrusion 76 comes into contact with the second protrusion 84 .

(3) As the first arm 64 continues to rotate, the third protrusion 76 pushes the second protrusion 84 (FIG. 7). The second arm 66 rotates about the second rotation shaft 80 when the second convex portion 84 is pushed. The second arm 66 rotates in a direction in which the second gripping portion 82 moves away from the block 62 .

(4) Rotate the first arm 64 to a position where the first grip part 72 does not enter the orbit of the block 62 when the turret board 24 rotates (FIG. 8). During this time, the third protrusion 76 is pushing the second protrusion 84, and the second arm 66 also rotates. The second grip part 82 of the second arm 66 is also moved to a position where it does not enter the orbit of the block 62.

By the above process, the block 62 that was being held by the first arm 64 and the second arm 66 is released. In this state, the turret plate 24 rotates, and when the other block 62 is placed at or near the specified position, the turret plate 24 stops. The process of holding the block 62 will now be described.

(5) The first arm 64 and the second arm 66 are in the state shown in FIG. 8, and from this state, the first gripping part 72 and the second gripping part 82 are brought closer to the block 62. The piston rod 88 is moved out of the cylinder 90 and the connecting portion 78 is moved away from the cylinder 90. The first arm 64 rotates around a first rotation axis 70. The first gripping portion 72 approaches the block 62 . In the middle, the third convex portion 76 comes into contact with the fourth convex portion 86 (FIG. 9).

(6) As the first arm 64 continues to rotate, the third protrusion 76 pushes the fourth protrusion 86 (FIG. 10). By pressing the fourth convex portion 86, the second arm 66 rotates about the second rotation shaft 80. The second gripping portion 82 approaches the block 62 .

(7) When the first arm 64 continues to rotate and the third protrusion 76 cannot press the fourth protrusion 86, the first protrusion 74 then comes into contact with the second protrusion 84 (FIG. 11). As the rotation continues, the first protrusion 74 pushes the second protrusion 84, and the second arm 66 rotates about the second rotation shaft 80. By continuing to rotate the first arm 64 and the second arm 66, the block 62 can be gripped by the first gripping part 72 and the second gripping part 82 as shown in FIG. The first grip part 72 and the second grip part 82 may grip the block 62 while pressing it.

When the motor 60 rotates the turret platen 24, the block 62 may shift from the predetermined position as indicated by reference symbol 62' in FIG. 9. The block 62 can be pushed by the first arm 64 and the second arm 66, moved to a predetermined position, and then grasped by the first arm 64 and the second arm 66. The block 62 moves to the predetermined position together with the turret platen 24. Therefore, the motor 60 for rotating the turret platen 24 does not need to have high positioning accuracy, making it easier to design. An induction motor can be used for the motor 60.

As described above, in the present application, the block 62 is gripped by the first arm 64 and the second arm 66, so that the turret plate 24 can be easily aligned. The motor 60 and the power unit 68 do not need to be enlarged.

[Embodiment 2]
As shown in FIG. 12, the first arm 64 may be provided with a first gear 100 and the second arm 66 may be provided with a second gear 102 as a cooperation mechanism. The first gear 100 rotates around the first rotating shaft 70. The second gear 102 rotates about the second rotating shaft 80. The first gear 100 and the second gear 102 are in mesh with each other. When the first arm 64 is rotated by the power of the power device 68, the first gear 100 is rotated. The second gear 102 rotates in accordance with the rotation of the first gear 100. The rotation of the second gear 102 causes the second arm 66 to rotate. When the first arm 64 rotates so that the first gripping part 72 moves away from the block 62, the second arm 66 rotates so that the second gripping part 82 moves away from the block 62 (FIG. 13). When the first arm 64 rotates so that the first gripping part 72 approaches the block 62, the second arm 66 rotates so that the second gripping part 82 approaches the block 62. When the first grip part 72 contacts the block 62, the second grip part 82 also contacts the block 62.

Although the first convex portion 74 and the second convex portion 84 are shown in FIGS. 12 and 13, the presence or absence of the first convex portion 74 and the second convex portion 84 is arbitrary.

The shapes of the first arm 64 and the second arm 66 are not limited, and for example, the first gripping part 72 and the second gripping part 82 may be extended as shown by reference numerals 72' and 82' in FIG. The number of parts for gripping the block 62 increases, making it easier for the first arm 64 and the second arm 66 to grip the block 62.
