SUMMERY OF THE UTILITY MODEL
[ problem to be solved by the utility model ]
The winding portion vibrates when the winding portion rotates. If the length of the winding unit is increased, the vibration is increased. In particular, when the winding section has reached a specific rotational speed, the vibration resonates and increases. If the rotation speed at which the vibration resonates is included in the rotation speeds at which the wire is wound, the wire may not be wound at the rotation speeds. Changing the chucks in accordance with the rotational speed used or changing the chucks for each fiber winding device requires a lot of labor and reduces the production efficiency.
Therefore, an object of the present invention is to provide a fiber winding device that does not restrict the rotation range of the wire winding by reducing the vibration.
[ means for solving problems ]
In order to solve the above problem, the fiber winding device of the present invention has the following configuration.
The utility model discloses a fibre coiling apparatus includes: a motor; a winding unit that is attached with a rotating shaft of the motor and rotates with the rotation of the rotating shaft to wind a wire; a holding portion that rotatably holds the rotating shaft; and a load unit for applying a load to the motor, the holding unit, or both.
In the fiber winding device, the load section is a weight attached to the holding section or a power device that applies a force to the holding section.
In the fiber winding device, the holding portion includes:
a bearing installed at the rotating shaft;
a cover mounted on an outer circumference of the bearing;
an elastic part mounted on the outer circumference of the cover; and
and a fixing portion mounted on the cover via the elastic portion.
In the fiber winding device, the power device may change a force applied to the holding portion.
[ effects of the utility model ]
According to the present invention, it is found that the rotation range in which the resonance is increased changes by applying a load to the motor, the holding portion of the chuck, or both, but the vibration itself at the time of resonance is reduced, and therefore, even if the rotation speed at the time of winding the wire rod includes a peak value, winding is possible. By making the rotation speed when the vibration is generated higher than the rotation speed when the wire is wound in the winding portion, the wire can be wound in the winding portion at the time of small vibration.

Detailed Description
The fiber winding device of the present invention will be described with reference to the drawings. Although a plurality of embodiments are described, the same components may be denoted by the same reference numerals and the description thereof may be omitted even in different embodiments.
[ embodiment 1]
The fiber winding device 10 of the present application shown in fig. 1 includes: a bundling machine (bundling die) 14 for bundling a plurality of filaments 12 to form a wire 16, a guide 18 for applying a predetermined tension to the wire 16, a traverse device (traverse device)20 for changing the position of the wire 16, a chuck 22 for winding the wire 16, and a turntable 24 to which the chuck 22 is attached.
The filaments 12 are single fibers, and are, for example, glass fibers, basalt fibers, natural fibers, synthetic fibers, carbon and other inorganic fibers. The buncher 14 is a roller comprising a groove (fig. 2). A plurality of filaments 12 are bundled by one slot. The wire 16 is formed by bundling a plurality of filaments 12. The single rotating shaft 26 may include a plurality of rollers, or the wide roller may include a plurality of grooves. By having a plurality of grooves, a plurality of wires 16 can be formed simultaneously.
The guide 18 is disposed between the buncher 14 and the collet 22. The wire 16 is in contact with the guide 18, and tension is applied to the wire 16. The guide 18 is a roller including a groove or a comb-shaped plate body. The guide 18 shown in fig. 2 is a roller including a groove, and the guide 18 is included in comparison with the number of the wires 16. In fig. 2, all guides 18 are mounted on one rotating shaft 28. All guides 18 rotate simultaneously. Further, the guides 18 are provided independently, and the guides 18 may rotate independently.
A traverse device 20 is included between the guide 18 and the collet 22. The traverse device 20 includes a rotary shaft 30 and a wire 32. The wire 32 is a curved linear body. The wire 32 is mounted on the rotating shaft 30. The wire 16 is pushed by the wire 32, and is rotated by the rotating shaft 30, and the wire 16 moves along the shape of the wire 32. The wire 16 reciprocates in the direction of the rotation axis of the chuck 22. When the wire 16 is wound around the chuck 22, the wire 16 is wound while reciprocating in the rotational axis direction of the chuck 22, and a cake 34 in which the wire 16 is gathered together is formed. The number of cakes 34 formed in one cartridge 22 is not limited, and four cakes 34 may be formed as shown in fig. 2. The detailed structure of the chuck 22 will be described later.
As shown in fig. 1, the turntable 24 has two winding units including the chucks 22. The two chucks 22 are disposed at positions symmetrical with respect to the center of the turntable 24. The position of the chuck 22 on one side is a winding position of the wire 16, and the position of the chuck 22 on the other side is a take-out position of the cake 34. A spacer plate 36 is included between the two collets 22. The cartridge 22 in the take-up position is rotated by a motor. If cake 34 is formed on chuck 22 on one side, turntable 24 is rotated to reverse the position of chuck 22, which in turn rotates chuck 22 on the other side.
In order to remove a cake 34 from a chuck 22 located in the removal position of the cake 34, a receiving member 38 and a moving device 40 for moving the receiving member 38 are provided. Receiving member 38 supports cake 34 from below. The moving means 40 includes a servo motor, a ball screw, an air cylinder, or the like. The moving device 40 moves the receiving member 38 in the rotational axis direction of the chuck 22. Receiving member 38 supports cake 34 such that cake 34 moves toward first end 58 of chuck 22. Cake 34 can be removed from chuck 22. Alternatively, a doffer may be used to remove the cake 34. Further, when the cake 34 is manually removed from the chuck 22, the receiving member 38 and the moving device 40 may be omitted.
The fiber winding device 10 includes a pushing-out device 42 that moves the position of the wire 16 that moves between the guide 18 and the collet 22. The pushing device 42 includes a pushing rod 44 for pushing out the wire 16, and an air cylinder for advancing and retreating the pushing rod 44. A push-out rod 44 is attached to a piston rod 46 of the cylinder. After chuck 22 completes cake 34, ejector bar 44 is advanced to push wire 16 outward of cake 34 (fig. 3) before turntable 24 rotates. Wire 16 is not wound around cake 34 but is wound around slot 66 near first end 58 of collet 22. When the dial 24 is rotated, the wire 16 is rewound from the vicinity of the first end 58 of the first chuck 22 toward the groove 66 in the vicinity of the first end 58 of the second chuck 22. Thereafter, the push-out rod 44 is returned to the original position, whereby the wire 16 is wound around the other chuck 22.
The fiber winding device 10 includes a spraying device 48 that sprays a liquid such as water. When the turntable 24 rotates, the wire 16 is rewound from the chuck 22 on the one side toward the chuck 22 on the other side. At this time, the rotation of the collet 22 on one side is stopped, and the rotation of the collet 22 on the other side is started, whereby the wire 16 is pulled, transferred by a difference in rotation of the collet 22, and cut by bending of the wire 16 at the time of winding. When the wire 16 is cut, the fine filaments 12 may scatter. The liquid is blown to the strand 16 by the spray device 48, thereby preventing the scattering of the filaments 12. The spraying device 48 is provided as needed.
As shown in fig. 4, the fiber winding device 10 of the present application is provided with a winding unit 52 for winding the thread material 16 on the turn table 24. The take-up section 52 contains the cartridge 22. Further, the chuck includes a motor 50 for rotating the chuck, a holding portion 54 for rotatably holding a rotation shaft of the motor 50, and a load portion 56.
The winding section 52 includes: a shaft member 62 having a first end 58 and a second end 60, a plurality of long plates 64 arranged on the outer periphery of the shaft member 62, and a groove 66 provided in the vicinity of the first end 58. A rotary shaft 68 (fig. 5) of the motor 50 is attached to the shaft member 62. The winding portion 52 is rotated by the power of the motor 50. The shaft member 62 is cylindrical or columnar, and a plurality of long plates 64 are attached so as to be wound around the outer periphery of the shaft member 62 in one turn. The long plates 64 are radially moved about the shaft member 62 by a power unit. When the wire 16 is wound, the long plate 64 moves in a manner of being separated from the shaft member 62, and when the cake 34 is taken out, the long plate 64 moves toward the shaft member 62. The first end 58 of the shaft member 62 is open, and the second end 60 is disposed on the holding portion 54 side. The groove 66 near the first end 58 temporarily winds the wire 16 as described.
The holding portion 54 includes: bearing 70, cover 72, elastic part 74 and fixing part 76. The bearing 70 rotatably holds the rotary shaft 68, for example, a ball bearing. The cover 72 is attached to the outer periphery of the bearing 70 and covers the rotary shaft 68 and the bearing 70. A fixing portion 76 is attached to the outer periphery of the cover 72. The fixing portion 76 is fixed to the turntable 24. The retainer portion 76 may also be part of the turntable 24. An elastic portion 74 is disposed between the cover 72 and the fixing portion 76. The elastic portion 74 is, for example, an O-ring (O ring) made of an elastic material such as rubber. The number of the elastic portions 74 may be plural. The elastic portion 74 absorbs the vibration of the winding portion 52 when rotated.
The load portion 56 is attached to the holding portion 54. The load portion 56 of the present embodiment is a heavy object. Although not limited to the present solution principle, it is considered that the load section 56 applies a load to the holding section 54, the center of gravity of the cartridge 22 located in the winding section 52 moves in the direction of the motor 50, and the center of gravity moves to change the vibration of the winding section 52 when rotating. The waveform X1 in fig. 6 is a conventional waveform, and includes the load portion 56, so that the amplitude (vibration) of the winding portion 52 resonates and increases as the rotation speed of the winding portion 52 increases, as in the waveform X2. For example, in the conventional case where the vibration of the winding portion 52 is increased when the rotation speed of the winding portion 52 is about 3000rpm, the vibration of the winding portion 52 is increased when the rotation speed of the winding portion 52 is about 5000rpm by the load portion 56. If the rotation speed at which the vibration becomes large becomes higher than the rotation speed at the time of winding the wire material 16, the winding of the wire material 16 is not affected any more. The vibration itself at the resonance rotational speed becomes small.
The load unit 56 is attached to the motor 50 side with respect to the fixing unit 76 of the holding unit 54. This is to facilitate the center of gravity of the cartridge 22 located in the winding portion 52 to move in the direction of the holding portion 54.
The load unit 56 is attached with a plate-like weight from two directions. When the turntable 24 rotates, the load unit 56 also rotates. The load portion 56 is disposed so as not to collide with other members. The shape of the load portion 56 is not limited as long as the load portion 56 does not collide with other members. When the chuck 22 is located at the winding position of the wire 16, a load is applied in the direction of gravity.
A tube 78 (fig. 2) is attached to the winding portion 52 of the cartridge 22. When the tube 78 is attached to the collet 22 and the long plate 64 is moved so as to be separated from the shaft member 62, the tube 78 is fixed. The tube 78 rotates together with the winding unit 52. Wire 16 is wound onto tube 78 to form cake 34. A cake 34 is formed in a tube 78. When the long plate 64 moves toward the shaft member 62, the tube 78 falls off from the chuck 22. Receiving member 38 moves tube 78 with cake 34. The same number of tubes 78 as the number of cakes 34 formed in one cartridge 22 are installed in the cartridge 22. The tube 78 is made of paper or resin.
As described above, the center of gravity of the cartridge 22 located in the winding portion 52 moves toward the motor 50, and the rotation speed when the vibration of the winding portion 52 increases. The weight of the load portion 56 is adjusted so that the rotation speed at which the vibration becomes large becomes higher than the rotation speed at the time of winding the wire material 16. The vibration of the winding section 52 does not increase when the wire material 16 is wound, and the wire material 16 can be wound around the winding section 52. Since the vibration of the resonance rotation speed is also reduced, the wire 16 can be wound even if the winding rotation speed and the resonance rotation speed overlap.
[ embodiment 2]
The chuck 22 may be a load unit 80 (fig. 7) including a power unit such as an air cylinder or a hydraulic cylinder. The load part 80 is fixed to the turntable 24. The holding portion 54 is pressed by the piston rod 82. The pressed portion is a portion of the holding portion 54 on the motor 50 side. The holding portion 54 is pressed in a direction in which an upper portion of the holding portion 54 is pressed in a direction of gravity. A load is applied to the holding portion 54. As in embodiment 1, the rotation speed of the winding portion 52 at which the vibration of the winding portion 52 becomes large can be increased. Further, since the vibration of the resonance rotation speed is also reduced, the wire 16 can be wound even if the winding rotation speed and the resonance rotation speed overlap.
The pressing force by the load portion 80 may be changed. The rotation speed of the winding portion 52 is fast when the winding of the wire material 16 is started, and the rotation speed of the winding portion 52 is slow as the wire material 16 is wound. The force of the load portion 80 is reduced when the winding of the wire material 16 is started. When the rotation speed of the winding portion 52 is reduced, the force of the load portion 80 is increased. When the force of the load portion 80 is small, the vibration becomes large when the rotation speed of the winding portion 52 becomes high. When the force of the load portion 80 is large, the vibration becomes large when the rotation speed of the winding portion 52 is slow. That is, the load section 80 applies a load so that the vibration of the winding section 52 does not increase in accordance with the rotation speed of the winding section 52.
The load portion 80 may be provided in plural numbers, and the load may be applied to the holding portion 54 from plural directions.
The load portion 80 may be fixed to any member that does not rotate, not to the turntable 24. When the chuck 22 is rotated by the dial 24 and is disposed at the winding position, the piston rod 82 is extended to apply a load to the holding portion 54. When the winding of the wire is completed, the piston rod 82 is contracted and separated from the holding portion 54. When the turntable 24 is rotated, the chuck 22 may be rotated together. Further, when the turntable 24 rotates, the load unit 80 may be moved to allow the turntable 24 to rotate.
[ embodiment 3]
As shown in fig. 8, the screw 84 may apply a load to the holding portion 54. The screw 84 passes through a fixing member 88 having a screw hole 86. The fixing member 88 is fixed to an arbitrary portion of the turntable 24. The screw 84 has a tip end contacting the holding portion 54. By screwing the screw 84, the load on the holding portion 54 can be changed.
Further, the load may be applied to the holding portion 54 by a jack. One end of the jack is fixed with the other end abutting against the holding portion 54. The holding portion 54 is loaded by adjusting the height of the jack.
Further, the load portion 80 may be disposed below the holding portion 54, the holding portion 54 may be fixed to the piston rod 82, and the piston rod 82 may pull the holding portion 54 to apply a load to the holding portion 54. The state is the same as the state in which the load is applied from above the holding portion 54. The structure of the load portion 80 is not limited as long as a load can be applied to the holding portion 54.
[ embodiment 4]
In all the embodiments described above, a load is applied to the holding portion 54, but a load may be applied to the motor 50 by the same configuration as that of the embodiments described above. Further, the motor 50 and the holding portion 54 may be loaded by the same configuration as that of the above-described embodiment.

The rotation speed of the winding unit when the vibration of the chuck becomes large becomes high, and may be different from the rotation speed when the wire is actually wound. The wire can be wound in a state where the vibration of the chuck is small. Since the vibration of the resonance rotation speed is reduced, the wire can be wound even if the winding rotation speed of the wire overlaps the resonance rotation speed.
(second item) the load section is a weight mounted on the holding section or a power device that applies force to the holding section.
According to the fiber winding device described in the second aspect, the load section may apply a load to the holding section not only by the weight but also by a power member such as an air cylinder or a hydraulic cylinder.

(fourth item) the power unit may change the force applied to the holding portion.
According to the fiber winding device described in the fourth aspect, the force can be adjusted so that the vibration of the chuck becomes small in accordance with the rotation speed of the winding unit.
The present invention can be implemented in embodiments to which various improvements, modifications, and changes have been made according to the knowledge of those skilled in the art, without departing from the scope of the present invention. The embodiments described are not independent embodiments and can be implemented by appropriate combinations according to the knowledge of a person skilled in the art.
