Detailed Description

The fiber winding apparatus of the present application will be described with reference to the accompanying drawings. Although the embodiments are described, the same reference numerals are given to the same components even in different embodiments, and the description thereof may be omitted.

Embodiment 1

The fiber take-up device 10 of the present application shown in fig. 1 includes: a bundling device (bundling brush) 16 for bundling a plurality of filaments 12 to form a wire 14, a guide 18 for applying a predetermined tension to the wire 14, a collet 20 for winding the wire 14, and a traverse device 22 for changing the position of the wire 14 when the wire 14 is wound around the collet 20.

The filaments 12 are single fibers, for example, glass fibers, basalt fibers, natural fibers, synthetic fibers, inorganic fibers such as carbon, and the like. The buncher 16 is a roller including a groove (fig. 2). The plurality of filaments 12 are bundled by one slot. The wire 14 is formed by bundling a plurality of filaments 12.

The guide 18 is disposed between the cluster 16 and the collet 20. The wire 14 is in contact with the guide 18, and tension is applied to the wire 14. The guide 18 is a roller or comb-like plate body including grooves. The guide 18 shown in fig. 2 is a roller comprising grooves.

The collet 20 has a cylindrical shape or a columnar shape. Including a first motor 24 (fig. 2) that rotates the collet 20. The wire 14 is wound around the outer periphery of the collet 20. A cylindrical tube 26 may be attached to the outer periphery of the collet 20, and the wire 14 may be wound around the tube 26. The tube 26 comprises paper or resin.

As shown in fig. 1, two chucks 20 are mounted on the turntable 28. The two chucks 20 are arranged in symmetrical positions with respect to the center of the turntable 28. A spacer plate 32 is included between the two chucks 20. A motor (not shown) for rotating the turntable 28 is included. The position of the chuck 20 on one side is the winding position of the wire 14, and the position of the chuck 20 on the other side is the removal position of the completed cake 30. The cartridge 20 in the winding position is rotated by the first motor 24. If the spin cake 30 is formed on the chuck 20 on one side, the turntable 28 is rotated to change the position of the chuck 20.

The fiber winding apparatus 10 includes an ejector 34 that moves the position of the wire 14 that moves between the guide 18 and the collet 20. The ejector 34 includes an ejector rod 36 for ejecting the wire 14, and a power device such as a cylinder or a hydraulic cylinder for advancing and retreating the ejector rod 36. For example, a push rod 36 is attached to a piston rod 38 of the cylinder. After the chuck 20 completes the cake 30, the push rod 36 is advanced before the turntable 28 rotates, and the wire 14 is pushed out of the cake 30 (fig. 3). The wire 14 is not wound around the cake 30, but is wound around the slot 42 near the end 40 of the collet 20. When the turntable 28 rotates, the wire 14 is rewound from the vicinity of the end 40 of the one chuck 20 to the groove 42 in the vicinity of the end 40 of the other chuck 20. Thereafter, the push-out bar 36 is returned to the original position, whereby the wire 14 is wound around the collet 20 on the other side.

The fiber winding apparatus 10 may include a spraying device 44 for spraying a liquid such as water. When the turntable 28 rotates, the wire 14 is rewound from the one collet 20 toward the other collet 20. At this time, the rotation of the one collet 20 is stopped, and the other collet 20 starts to rotate, whereby the wire 14 is pulled, and the wire 14 is bent and cut at the time of winding. When the wire rod 14 is cut, the filaments 12 which have become fine may be scattered. The spraying device 44 blows the liquid toward the wire 14 to prevent the filaments 12 from scattering.

A traversing device 22 is included between the guide 18 and the collet 20. As shown in fig. 2, the traversing device 22 includes a rotating shaft 46, a helical wire 48, and a second motor 50. As shown in fig. 4, the spiral line 48 is a linear body including a curved portion in at least a part thereof. Two spiral wires 48 are mounted on the rotation shaft 46. When the second motor 50 rotates the rotation shaft 46, the spiral wire 48 also rotates in accordance with the rotation of the rotation shaft 46. The wire 14 is pushed against by the spiral wire 48. By rotating the rotation shaft 46, the wire 14 moves along the shape of the spiral line 48. The wire 14 reciprocates in the longitudinal direction of the rotation shaft of the collet 20. When the wire 14 is wound around the collet 20, the wire 14 is wound while reciprocating in the longitudinal direction of the rotation shaft of the collet 20. Forming a cake 30 of a predetermined shape. The shape and number of the spiral lines 48 are not limited as long as the wire 14 can reciprocate.

Comprising control means 52 for controlling the rotational speed of the first motor 24, the rotational speed of the second motor 50 or both. The control device 52 includes an arithmetic device such as a central processing unit (Central Processing Unit, CPU) or a programmable logic controller (Programmable Logic Controller, PLC). The rotational speed of the chuck 20 is controlled by controlling the rotational speed of the first motor 24. The rotational speed of the spiral 48 is controlled by controlling the rotational speed of the second motor 50. The lead angle when the wire 14 is wound around the collet 20 is controlled by controlling the rotational speed of the collet 20, the rotational speed of the spiral wire 48, or both. The control device 52 controls the rotation speed of the first motor 24, the rotation speed of the second motor 50, or both to control the lead angle of the wire rod 14 to be an inputted value.

The lead angle is an angle of the wire 14 in the vertical direction with respect to the rotation axis of the collet 20. For example, as shown by dashed line 54 in fig. 5, the wire 14 traverses a single pass during two rotations of the collet 20, wrapping two turns around the surface of the cake 30. When the surface of the cake 30 is spread, the lead angle is α as shown in fig. 6 _n 。

For example, the rotation speed of the first motor 24 and the rotation speed of the second motor 50 are fixed. In this case, as the cake 30 is formed, the diameter of the cake 30 becomes larger, and thus the lead angle becomes smaller. A lead angle at the start of winding of the wire rod 14 is alpha ₀ The lead angle at the end of winding of the wire rod 14 (at the completion of the cake 30) is α _f In the case of (2), becomes alpha ₀ ＞α _f . When the lead angle is reduced, the direction of the wire 14 approaches the vertical direction with respect to the rotation axis of the collet 20. When the wire 14 is wound in a direction perpendicular to the rotation axis of the collet 20, a stronger force can be applied to the wire 14 than when the wire 14 is wound obliquely. Therefore, as the lead angle becomes smaller, the winding-up degree of the wire 14 becomes stronger.

On the other hand, the present application can control the lead angle by controlling the rotational speed of the first motor 24, the rotational speed of the second motor 50, or both using the control device 52. As the wire 14 is wound, the rotation speed of the first motor 24 is slowed, or the rotation speed of the second motor 50 is increased, or both. By setting the lead angle to a predetermined value, the force at the time of winding the wire rod 14 can be controlled from the start of winding the wire rod 14 to the completion of the cake 30. The take-up of the wire 14 can be prevented from becoming gradually stronger as described.

The present application includes a timing device 56. The timing device 56 starts timing when the winding of the wire 14 around the collet 20 is started. The time measured by the timer 56 is input to the control device 52. The time from the start of winding the wire 14 is counted, whereby the control device 52 can control the rotational speeds of the motors 24, 50 in correspondence with the time. For example, when the push rod 36 of the push-out device 34 is in the state of being housed inside (fig. 2) from the state of being extended forward (fig. 3), a signal is input from the control device 52 to the timer device 56, and the timer device 56 starts to count time. Further, the control device 52 is configured to control the power unit of the ejector 34, and thus, when the state of fig. 3 is changed from the state of fig. 2, a signal can be sent from the control device 52 to the timer 56.

The present application includes a lead angle input device 58. The input device 58 includes a touch screen, buttons, or both included in the fiber take-up device 10. The operator of the fiber winding device 10 inputs the lead angle α using the input device 58 _n . Inputted lead angle alpha _n Is inputted into the control device 52 to set the lead angle alpha _n . The control device 52 sets the lead angle alpha _n The rotational speed of the first motor 24, the rotational speed of the second motor 50, or both.

The first motor 24, the second motor 40, the control device 52, and the timer device 56 are housed in a housing 60. The input device 58 is mounted at an arbitrary position of the housing 60.

Next, an example of a method for determining the rotational speed of the first motor 24 and the rotational speed of the second motor 50 will be described. Lead angle α at which winding of wire rod 14 is started ₀ From the lead angle alpha at the time of completed cake 30 _f If the difference is Δα, Δα is expressed by the following equation 1. If the rotational speed of the collet 20 at the start of winding the wire 14 is set to V ₀ The rotational speed of the chuck 20 when the cake 30 is completed is set to V _f Assuming that the difference in rotational speeds of these chucks 20 is Δv, Δv is expressed by the following equation 2.

[ mathematics 1]

Δα＝α _f -α ₀

[ math figure 2]

ΔV＝V _f -V ₀

In setting the lead angle that has been input into the control device 52 to alpha _n The winding time from the start of winding the wire rod 14 to the completion of the cake 30 is T, and the elapsed time from the start of winding the wire rod 14 is T _n When the lead angle change index is B, the lead angle α _n The following equation 3 is obtained.

[ math 3]

[ mathematics 4]

If the diameter of the collet 20 or tube 26 is set to D ₀ The average winding diameter when forming the cake 30 is set as D _n D is then _n The following equation 5 is obtained.

[ math 5]

When the rotation speed of the second motor 50, that is, the rotation speed of the rotary shaft 46 is set to Y, Y is expressed by the following equation 6.

[ math figure 6]

When the control device 52 inputs the lead angle α from the input device 58 _n Then at the lead angle alpha _n Control the rotational speed V of the chuck 20 so as to be the same as the inputted value _n And the rotational speed Y of the second motor. The rotational speed V _n The control of the rotational speed Y is controlled so as to change linearly.

As described above, the control device 52 of the present application controls the first motor 24, the second motor 50, or both, and controls the lead angle to a set value, thereby preventing the wire 14 from being strongly wound up as the wire 14 is wound. The rotational speed of the first motor 24 and the rotational speed of the second motor 50 are controlled in a linear fashion, and the force of the wire 14 when wound around the collet 20 can be controlled.
