DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a striated body guide for a striated winding machine capable of improving the striated body alignment during winding by a simple mechanism.

[0002]

2. Description of the Related Art A conventional wire winding machine is provided with a wire guide (traverser guide) for guiding a wire in order to prevent winding disturbance during a winding operation. The striated body guide is fixedly arranged outward from the flange of the bobbin on which the striated body is wound, and when the striated body is wound, the bobbin rotates and reciprocates in parallel with the bobbin axis. The striatum is wound on a bobbin. In such a striated body guide, the distance between the striated body winding point on the bobbin and the striated body guide is increased because the striated body guide is outwardly separated from the bobbin flange, and winding disturbance is likely to occur. There was a disadvantage.

Therefore, as disclosed in Japanese Patent Application Laid-Open No. Hei 2-270772, a pair of guide pieces (striated body guides) formed of a thin metal band and forming slits for sandwiching the striated body are provided. A wire winding device has been devised in which the guide piece is disposed inside the flange and the guide piece gradually moves outward as the winding diameter of the filament increases. Since the guide strip guides the striated body immediately near the winding point on the bobbin side, it is possible to prevent the occurrence of winding disturbance. Furthermore, this device has a mechanism in which the guide piece on the flange side escapes outward when the guide piece is close to the bobbin flange, so that the filament is also formed at the beginning of winding (when the guide piece is close to the bobbin flange). The body can be guided along the bobbin flange end surface and wound up without any gap.

[0004]

However, since the thin strip-shaped guide piece is used in the conventional wire rod guide of the wire winding device, 1) the guide piece is set well when used for a long time. 2) It is difficult to adjust the slit width according to the diameter of the guided striated body. 3) The guide piece escape operation mechanism when the guide piece is close to the bobbin flange is complicated. On the other hand, a guide having only one side has a problem of lack of reliability.

[0005]

DISCLOSURE OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and has been made in consideration of the above-mentioned problem. In a striated body guide of a striated winding machine arranged near a bobbin to prevent the striated winding of the striated body, an arm and two guide wires laid parallel to both ends of the arm A pin which is detachably attached near both ends of the arm and is inserted between the two guide wires to expand and contract the interval between the wires; and a pin provided at at least one end of the arm to apply tension to the guide wire. And a tension applying means.

[0006]

FIG. 1 shows an embodiment of a striated body guide of a wire rod winding device according to the present invention. An arcuate arm 3 is attached to both ends of the arm 3 and is stretched between both ends. A guide wire 4 composed of two wires, a tension applying portion 2 for fixing the guide wire 4 at one end of the arm 3 and applying a tension to the wire by a repulsive force of the spring 1, and near a both end of the arm 3. It comprises a detachable cylindrical pin 9 inserted between two guide wires 4, and a rotary actuator 5 connected to the other end of the arm 3 by a drive shaft to swing the arm 3. You.

Here, a slit for guiding the striatum 10 is formed by inserting the pin 9 between two guide wires 4 which are stretched closely and in parallel. The interval between the slits can be adjusted by exchanging the pins 9 having different diameters to expand and contract the width between the two guide wires 4. The shape of the pin 9 may be any shape as long as a slit having a predetermined width can be formed between the guide wires 4, and those having a cross section such as a polygonal shape, a flat shape, etc. in addition to a columnar shape are also applicable.

The tension applying section 2 has a spring 1 and always applies tension to the guide wire 4, so that even when used for a long period of time, the guide wire 4 is kept taut without causing settling of the guide wire 4. The wire 4 is surely the striatum 1
0 can be guided. Note that this tension applying section 2
As the elastic means for applying tension in (1), any commonly used elastic means other than a coil spring and a leaf spring can be applied. Further, the tension applying portions can be provided at both ends of the arm.

FIG. 1 shows the guide operation by this striatum guide.
This will be described below with reference to FIGS. The striated body 10 is inserted through the fixed guide pulley 8 between two guide wires 4 of the striated body guide disposed immediately near the winding point of the bobbin, and supplied to the bobbin 6. The winding is performed by rotating the bobbin 6 and reciprocating a bobbin traverser 7 connected in the axial direction of the bobbin 6 in the same direction.

[0010] As the winding progresses, the winding diameter increases due to the overlapping of the filaments 10, but as shown in FIG.
By swinging the arm, the arm 3 gradually moves outward so as to separate from the bobbin 6, and the distance between the winding point and the striatum guide can be kept constant. When the striated body guide approaches the flange of the bobbin 6, for example, at the beginning of winding of the striated body 10, the portion of the pin 9 in contact with the guide wire 4 is decentered with respect to the mounting portion to the arm 3. Pin 9
By rotating the guide wire 4, as shown in FIG. 3, the position of the guide wire 4 shifts in a direction closer to the flange of the bobbin 6, so that the striated body 10 is guided along the flange end of the bobbin 6. It can be wound without gaps.

[0011]

As described above in detail, according to the wire guide of the wire winding device of the present invention, the wire is disposed near the bobbin in order to prevent the wire wound on the bobbin having the flanges on both sides from being disturbed. A striated body guide of a striated winding machine, wherein: an arm, two guide wires that extend in parallel with both ends of the arm, and detachably attached near both ends of the arm. It has a simple structure because it is composed of a pin inserted between the guide wires to expand and contract the interval between the wires, and tension applying means provided at at least one end of the arm and applying tension to the guide wire. It is possible to reliably guide the winding of the striated body.

[0012] Therefore, it is possible to prevent the striated body from being irregularly wound at the time of winding and to improve the space factor of the striated body.
