Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for winding a monofilament material of a slide fastener, a linear body such as a thread, a rope or the like on a bobbin having a taper flange.

[0002]

2. Description of the Related Art As a device for winding a linear body on a bobbin,
A device is known that includes a mechanism for rotating a bobbin and a traverse mechanism that reciprocates (that is, traverses) the linear body guide in the bobbin axial direction, and properly winds the linear body by laminating it onto the bobbin winding body. There is.

If the bobbin described above is a bobbin with a tapered flange having opposing tapered flanges having tapered winding surfaces on both sides of the winding barrel, the winding width increases as the winding diameter of the linear body increases. Is increased sequentially, it is necessary to increase the reciprocating distance (that is, the traverse width) of the linear body guide. For example, as disclosed in Japanese Patent Application Laid-Open No. 58-167358, a winding device has been proposed in which the traverse width of the linear body guide is increased according to the winding diameter of the linear body of the bobbin.

In the above-mentioned winding device, the swing rod is moved in the bobbin axial direction by the rotation of the two traverse screw shafts, and at both ends of the bobbin, it is slanted, and the slider is attached to the frame structure provided with the linear body guides. Is movably provided by a motor and a screw shaft, and its slider is slidable in the longitudinal direction of the oscillating rod, and the screw shaft is rotated by the motor according to the winding diameter to make the slider an oscillating rod. By sliding along, the linear body guide is moved in the axial direction of the bobbin to adjust the traverse width.

[0005]

In the above-described winding device, since a plurality of members are operated to change the traverse width, an error easily occurs in the traverse width with respect to the winding diameter. Further, since a large number of members such as two traverse screw shafts, a swing rod, a frame structure, a motor, a screw shaft, and a slider are used, the structure is complicated and an operation error is likely to occur in each member. These operation errors may be combined to cause a large error in the traverse width with respect to the winding diameter.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a winding device for a linear body which can solve the above-mentioned problems.

The first nut member 65 is provided with a ball that contacts the spiral groove 62, and the second nut member 66 is provided with an engaging piece that engages with the spline 63. When the first nut member 65 rotates forward and backward, the traverse shaft 60 moves in the axial direction, and the second nut member 6

The output side of the speed reducer 68 is connected to the first nut member 65 via a timing pulley 70, a timing belt 71, and a timing pulley 72.

Therefore, when the servo motor 69 is driven to rotate the first nut member 65 forward and backward, the traverse shaft 60 reciprocates in the axial direction, thereby forming the traverse mechanism 25.

The base end of the winding diameter measuring arm 5 is shown in FIG.
As shown in FIG. 3, it is fixed to one end of the measuring shaft 80, and a measuring roller 81 is rotatably attached to the tip thereof. As shown in FIG. 5, the other end of the measuring shaft 80 is rotatably supported by a bearing 83 on a cylindrical body 82 fixed to the substrate 22, and a potentiometer 84 rotates on the other end of the measuring shaft 80.

As shown in FIG. 7, the expansion chamber 91a and the contraction chamber 91b of the cylinder 91 are provided with a switching valve 92 and an air source 9
3 and the atmosphere are controlled. When the switching valve 92 is set to the first position a, air is supplied to the extension chamber 91a, the third gear 88 moves in the direction of arrow c, and the traverse arm 4 and the winding diameter measuring arm 5 swing in the direction of arrow. As shown by the alternate long and short dash line in FIG.
0, and the linear body guide 11 comes closest to the bobbin 3. The air pressure in the expansion chamber 91a is low by the pressure reducing valve 94,
For example, it is set to 3 kg / cm ^2, and the swinging force of the winding diameter measuring arm 5 is weak. When the linear body is wound and the winding diameter becomes large, the linear body swings in the opposite direction.

When the switching valve 92 is set to the second position b, air is supplied to the compression chamber 91b, the third gear 88 moves in the direction of arrow d, and the traverse arm 4 and the winding diameter measuring arm 5 are opposite to the arrow. The linear body guide 11 and the measuring roller 81 swing in the direction of the bobbin 3 as shown by the two-dot chain line in FIG.
Get away from. As a result, when the bobbin 3 is attached to and removed from the bobbin rotating shaft 2, they do not get in the way.

When the winding diameter measuring arm 5 swings, the measuring shaft 80 rotates, and the rotation thereof is controlled by the potentiometer 84.
The detection signal of the potentiometer 84 is input to the controller 100 as shown in FIG. The controller 100 calculates the winding diameter based on the input signal,
The traverse width according to the winding diameter is calculated. Servo motor 6 for traverse based on the calculated traverse width
The energization to 9 is controlled to match the actual traverse width with the calculated traverse width.

For example, the size and shape of the bobbin 3 and the linear body 7
The traverse width L corresponding to the winding diameter is calculated in advance based on the diameter. Further, the number of rotations of the traverse servo motor 69 corresponding to the traverse width set based on the pitch of the spiral groove 62 of the traverse shaft 60, the reduction ratio, etc. is calculated,
The controller 100 sets the energization time corresponding to the rotation speed. Then, by selecting an energization time corresponding to the traverse width corresponding to the detected winding diameter and changing the energization time to the traverse servo motor 69, the linear body guide 11
Move by the traverse width corresponding to the winding diameter. In addition,
The controller 100 may calculate the traverse width, the rotation speed of the servo motor 69, and the energization time according to the input winding diameter.

Further, the controller 100 controls the amount of electricity supplied to the servomotor 33 for rotating the bobbin according to the input winding diameter, and slows down the rotation speed of the bobbin rotating shaft 2 as the winding diameter increases. The linear body 7 is wound with a constant tension. That is, as the winding diameter increases, the winding amount of the linear body per one rotation of the bobbin increases. Therefore, if the traverse speed is constant, the tension increases. Therefore, the rotation speed of the bobbin 3 is reduced to maintain the tension constant. To do.
