A fiber winding device of the present invention will be described with reference to the drawings.

A fiber winding device 10 of the present application shown in FIG. 1 includes a gathering shoe 14 that converges a plurality of filaments 12 to form a strand 16, a guide 18 that applies a predetermined tension to the strand 16, and a traverse device that changes the position of the strand 16. 20, a collet 22 for winding the strand 16 and a turret board 24 to which the collet 22 is attached.

The filament 12 is a single fiber, and is, for example, glass fiber, basalt fiber, natural fiber, synthetic fiber, inorganic fiber such as carbon, or the like. The gathering shoe 14 is a roller having a groove (FIG. 2). A plurality of filaments 12 are bundled in one groove. One strand 16 is formed by bundling 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. The strand 16 is in contact with the guide 18 and gives tension to the strand 16. The guide 18 is a roller provided with a groove or a comb-like plate body. The guide 18 shown in FIG. 2 is a roller having a groove, and the guide 18 is provided according to the number of strands 16. All the 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 shaft 30 and a traverse 32. The traverse 32 is a curved linear body. A traverse 32 is attached to the rotating shaft 30. The strand 16 is pressed against the traverse 32, and the rotation shaft 30 rotates, whereby the strand 16 moves along the shape of the traverse 32. The strand 16 reciprocates in the length direction of the rotating shaft of the collet 22. When the strand 16 is wound around the collet 22, the strand 16 is wound back and forth along the longitudinal direction of the rotation axis of the collet 22 to form a cake 40 in which the strand 16 is bundled. The number of cakes 40 formed on one collet 22 is not limited, and four cakes 40 may be formed as shown in FIG.

The collet 22 is included in the winding unit 36 that winds the strand 16. The rotating shaft of the motor 34 is attached to the collet 22. The collet 22 is rotated by the power of the motor 34. The holding part 38 includes a bearing. The bearing rotatably supports the rotating shaft of the motor 34, and the holding portion 38 rotatably holds the collet 22. The holding portion 38 is fixed to the turret board 24. When the turret board 24 rotates, the collet 22 also rotates.

As shown in FIG. 1, two collets 22 are attached to a turret board 24. The two collets 22 are arranged symmetrically with respect to the center of the turret board 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 taking-out position of the cake 40. A partition plate 42 is provided between the two collets 22. The collet 22 in the winding position is rotated by the motor 34. When the cake 40 is formed on one of the collets 22, the turret board 24 is rotated to replace the position of the collet 22, and then the other collet 22 is rotated.

In order to take out the cake 40 from the collet 22 at the take-out position of the cake 40, 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 length direction of the rotating shaft of the collet 22. The receiving member 44 supports the cake 40 and moves the cake 40 toward the first end 48 of the collet 22. The outer shape of the collet 22 can be reduced to remove the cake 40 from the collet 22. When the cake 40 is manually removed from the collet 22, the receiving member 44 and the moving device 46 may be omitted.

The fiber winding device 10 includes an extrusion device 50 that moves the position of the strand 16 that runs between the guide 18 and the collet 22. The extrusion device 50 includes an extrusion bar 52 that pushes the strand 16 and an air cylinder that moves the extrusion bar 52 back and forth. The push bar 52 is attached to the piston rod 54 of the air cylinder. Before the cake 40 is completed on the collet 22 and the turret board 24 is rotated, the extrusion bar 52 is advanced to push the strands 16 to the outside of the cake 40 (FIG. 3 ). The strand 16 does not wrap around the cake 40, but wraps around the groove 56 near the first end 48 of the collet 22. When the turret board 24 rotates, the strand 16 is rewound from the vicinity of the first end 48 of the one collet 22 into the groove 56 near the first end 48 of the other collet 22. Then, the extrusion bar 52 is returned to the original position, and the strand 16 is wound around the other collet 22.

The fiber winding device 10 includes a spray device 58 for ejecting a liquid such as water. When the turret board 24 rotates, the strand 16 is rewound from one collet 22 to the other collet 22. At that time, one of the collets 22 stops rotating and the other collet 22 starts to rotate, so that the collet 22 is transferred due to a difference in rotation of the collet 22 and is broken by the bending of the strand 16 when wound. It is cut by a cutter (not shown) provided on the partition plate 42. When the strands 16 are cut, the finely divided filaments 12 may scatter. Spraying the liquid onto the strands 16 with the spray device 58 prevents the filaments 12 from scattering. The spray device 48 is provided as needed.

The tube 60 is attached to the collet 22 (FIG. 2). The tube 60 rotates with the winding portion 36 of the collet 22. The strand 16 is wound on the tube 60 to form the cake 40. One cake 40 is formed in one tube 60. The receiving member 44 moves the tube 60 together with the cake 40. The same number of tubes 60 as the number of cakes 40 formed on one collet 22 are attached to the collet 22. The tube 60 is made of paper or resin.

A motor 34 for rotating the collet 22 and a motor (not shown) for rotating the turret board 24 are housed in a housing 62. The housing 62 is made of a corrosion resistant material such as stainless steel.

As shown in FIGS. 4 and 5, the front portion 64 of the housing 62 is a surface on which the collet 22 and the like are arranged. The front portion 64 of the housing 62 includes a first front cover 66, a first opening 68 provided in the first front cover 66, a first labyrinth structure 70 provided at the periphery of the first opening 68, and a first labyrinth structure 70. The second front cover 72, the second opening 74 provided in the second front cover 72, and the second labyrinth structure 76 provided at the periphery of the second opening 72 are provided.

The front portion 64 of the housing 62 has a double structure of a first front cover 66 and a second front cover 72. The first front cover 66 and the second front cover 72 are plate-shaped. The first front cover 66 and the second front cover 72 are parallel to each other. A gap 78 is provided between the first front cover 66 and the second front cover 72. The portion of the casing 64 other than the front portion 64 is formed of a plate-shaped member, and the casing 64 is a box.

The holding portion 38 of the collet 22 passes through the first opening 68 and the second opening 74. Further, the turret board 24 passes through the second opening 74 (FIG. 5). The first opening 68 and the second opening 74 are circular along the outer shape of the turret board 24. The turret board 24 rotates in the second opening 74. The rotation causes the holding portion 38 of the collet 22 to move within the first opening 68 and the second opening 74.

The first labyrinth structure 70 includes a first disk-shaped portion 80 and an eaves portion 82. The outer circumference of the first disk-shaped portion 80 is provided so as to go around the outside of the first opening 68 once. The first disk-shaped portion 80 is attached to the holding portion 38, the turret disk 24, or both, and rotates together with the turret disk 24. For example, the first disc-shaped portion 80 is provided with a third opening 84 through which the holding portion 38 of the collet 22 passes, the holding portion 38 of the collet 22 is passed through the third opening 84, and the first disc-shaped portion 80 and the collet 22 are The holding portion 38 is fixed without a gap. The eaves portion 82 covers the vicinity of the outer periphery of the first disk-shaped portion 80. The outer peripheral portion of the first disk-shaped portion 80 fits into the space formed by the first front cover 66 and the eaves portion 82. The eaves portion 82 is attached to the first front cover 66 and does not rotate. The eaves portion 82 is arranged in at least the upper half of the first opening 68 (FIG. 4).

The second labyrinth structure 76 includes a second disc-shaped portion 86. The outer circumference of the second disk-shaped portion 86 is provided so as to go around the outer side of the second opening 74. The second disk-shaped portion 86 is attached to the holding portion 38, the turret disk 24, or both, and rotates with the turret disk 24. For example, the second disc-shaped portion 86 is provided with a fourth opening 88 through which the holding portion 38 passes, and the holding portion 38 of the collet 22 is passed through the fourth opening 88. The second disk-shaped portion 86 is attached to the surface of the turret disk 24. No gap is formed between the second disc-shaped portion 86, the holding portion 38, and the turret disc 24.

Separators 90 and 92 are provided between the first front cover 66 and the second front cover 72 and between the first disk-shaped portion 80 and the second disk-shaped portion 86. The separators 90 and 92 form gaps 78 and 94 between the first front cover 66 and the second front cover 72 and between the first disk-shaped portion 80 and the second disk-shaped portion 86. The separators 90 and 92 are columnar or plate-shaped members.

When the collet 22, the turret board 24, and the front portion 64 of the housing 62 are cleaned with water, the first front cover 66 and the first disk-shaped portion 80 are splashed with water. The upper half of the first labyrinth structure 70 provided on the first front cover 66 can prevent water that falls in the direction of gravity from entering the gap 78 by the eaves 82. The first disk-shaped portion 80 can also prevent water at an angle close to horizontal from entering the gap 78. Further, the lower half of the first labyrinth structure 70 can prevent water falling in the direction of gravity and water having an angle close to horizontal from entering the gap 78 by the first disk-shaped portion 80.

If water reaches the gap 78, the first labyrinth structure 70 has no momentum in the water flow. Therefore, the second labyrinth structure 76 can prevent water from entering the housing 62.

As described above, the front portion 64 of the housing 62 of the present invention has the double structure of the first front cover 66 and the second front cover 72, and the first labyrinth structure 70 and the second labyrinth structure 76 are provided. Thus, water is prevented from entering the housing 62. Liquids other than water are similarly prevented from entering the housing 62. It is easy to protect devices such as the motor 34 arranged in the housing 62.

The present invention is not limited to the above embodiment. For example, the positions of the first front cover 66 and the second front cover 72 with respect to the turret board 24 are not limited to the configuration of FIG. As shown in FIG. 6, the fourth opening 96 of the second disk-shaped portion 86 may be an opening through which the turret disk 24 has passed. Further, as shown in FIG. 7, the third opening 98 of the first disk-shaped portion 80 and the fourth opening 96 of the second disk-shaped portion 86 may be openings through which the turret disk 24 has passed. If at least one of the holding portion 38 and the turret disk 24 passes through the third opening 98 and the fourth opening 96, the positions of the first disk-shaped portion 80 and the second disk-shaped portion 86 can be changed appropriately.

As shown in FIG. 8, the outer periphery of the first disk-shaped portion 102 may be bent toward the eaves portion 104. The tip of the eaves portion 104 may be bent toward the first disc-shaped portion 102. The bending of the first disc-shaped portion 102 and the eaves portion 104 makes it difficult for liquid to enter the gap 78. The outer circumference of the second disk-shaped portion 106 may be bent in the opposite direction of the second front cover 72. The liquid that has entered the gap 78 is unlikely to enter the internal space of the housing 62. The first labyrinth structure 70 and the second labyrinth structure 76 are not limited in structure as long as they can prevent liquid from entering.

The front portion 64 of the housing 62 includes two front covers 66 and 72 and two labyrinth structures 70 and 76, but the front cover and labyrinth structures may be further added.
