4 and the inner frame 16 placed on the winding table 13.
It is composed of.

The outer frame 14 includes a plurality of vertical ribs 14a which are fixed to the outer circumference of the take-up table 13 at equal intervals and whose upper ends are slightly curved outward, and an annular bone 1 that connects the upper ends of the vertical bones.
4b.

The inner frame 16 includes a seat bone 16a having an outer circumferential shape of four petals placed on the winding table 13, and a seat bone 16a which is erected on the seat bone 16a so as to surround the guide column 15 and connected to each other at the upper end. It is composed of four vertical ribs 16b.

The screw shaft 9 has a lower end rotatably supported on the take-up table 13 inside the guide column 15, and an upper end rotatably supported on the upper end of the guide column 15.

The receiving plate 11 is formed in a cross shape, and its outer end 11a is arranged between the vertical ribs 14a of the outer frame 14,
Moreover, it extends to the inside of the ischial bone 16a of the inner frame 16. Then, the nut 17 fixed to the center portion 11b of the receiving plate 11 is fitted onto the screw shaft 9,

The drive device 10 for the receiving plate 11 includes an external gear 20 that meshes with an internal gear 19 fixed to the lower end of the screw shaft 9.
It consists of a vertical shaft 21 and a drive motor 22 for rotating the vertical shaft 21.

Further, the rotational drive device 8 for the winding frame 7 is connected to a first gear 23 fitted to the lower end of the winding table 13 passing through the support table 12, and meshing with the first gear 23 to rotate the drive device 11. has a second gear 24 driven by a separate drive motor (not shown).

In this embodiment, the rotational speed of the screw shaft 9 is set higher than the rotational speed of the winding frame 7, and the difference in rotational speed between the winding frame 7 and the screw shaft 9 causes the receiving plate to
1 is configured to move up and down along a screw shaft 9.

Furthermore, the rocking device 6 which is the main part of the present invention
is a rotationally driven camshaft 25, and the camshaft 25
A disc-shaped eccentric cam 26 is fixed to the upper end and comes into contact with the rear end 5a of the arm 5, and the device main body 3 and the arm 5 The tension spring 27 is interposed between the tip end side of the tension spring 27.

The camshaft 25 is arranged outside the take-up frame 7 with its axial direction being the vertical direction.

The arm 5 is formed into a straight rod shape, and its rear part is supported by the pivot shaft 4 disposed outside the winding frame 7, and the arm 5 is connected to the winding drum 1 and the winding frame 7 below the winding drum 1. The winding frame 7 is disposed so that its length direction is substantially perpendicular to the radial direction of rotation of the winding frame 7. The arm 5 has a rear end 5a.
A circular contactor is brought into contact with the cam surface of the eccentric cam 26, and a first roller 28 for guiding the wire rod rotates around the horizontal axis at the tip 5b, and a first roller 28 rotates around the vertical axis at the tip of the first roller 28. A pair of second wire guide rollers 29 are supported, and these rollers 28,
29 has a function of guiding the wire rod that has fallen from the winding drum 1 so that it passes from the first roller 28 to the second roller 29 and falls onto the winding frame 7. and,
The swing range of the tip of the arm 5 is 1/2 of the diameter difference between the inner frame 16 and the outer frame 14, that is, the vertical bone 14a of the outer frame 14.
The position of the pivot shaft 4, the distance from the pivot shaft 4 to the rear end contact of the arm 5, and the shape of the cam 26 are set so as to be between the vertical bone 16b of the inner frame 16 and the vertical bone 16b of the inner frame 16.

Further, the arm 5 is set so that the number of rotations of the take-up frame 7 and the number of swings of the arm are slightly different. For example, the arm 5 is set to swing 99 times for every 100 rotations of the take-up frame 7.

Next, to explain the operation, first, the wire rod coming in from the wire input direction is once wound up on the rotating drum 1, then it slides on the roller surface of the first roller 28 of the guide arm 5 below the drum, and then it is moved to the second roller. 29
It passes through the gap and falls onto the receiving plate 11 of the winding frame 7.

On the other hand, the winding frame 7 and the screw shaft 9 are rotated by the respective drive devices 8 and 10, but their rotational speeds are slightly different, so that the tip 11a of the receiving plate 11 that is screwed onto the screw shaft 9 is rotated by the guide column. 15 (or the outer frame 14 of the winding frame 7), the receiving plate 11 attempts to rotate at the same rotational speed as the winding frame 7. Therefore, the receiving plate 11
is the screw shaft 9 due to the rotational speed difference between the winding frame 7 and the screw shaft 9.
If the receiving plate 11 descends in proportion to the amount of accumulated wire, the distance between the upper end of the wire 2 stored on the receiving plate 11 and the roller 29 of the arm 5 can be kept constant and small. to reduce suspended parts. In this case, the angle formed by the horizontal plane at the upper end of the storage line and the falling line becomes almost constant. Therefore, the influence of the centrifugal force exerted on the wire rod 2 while it is suspended in the air can be minimized, the falling angle remains unchanged and the state of the falling line is almost constant, and the appearance of the stacked wires is improved. Therefore, it is possible to wind a thin wire with a diameter of 1 mm, and the winding speed can be increased (from 150 m/min to 300 m/min).

Further, the arm 5 swings around the pivot shaft 4, and if the number of rotations (rotation period) of the winding frame 7 and the number of swings (swing period) of the arm are slightly different, the guide roller 29
The falling starting point of the wire rod 2 guided by moves in the horizontal direction, and the center A of the wire ring shape formed by one turn of the wire draws a trajectory B slightly eccentric from the axial center A1 of the screw shaft 9. For example, the arm 5 is swung 99 times for each 100 rotations of the take-up frame 7, and the amount of swiveling is adjusted to the inner frame 16.
If it is 1/2 of the diameter difference between the outer frame 14 and the receiving plate 11
The distance between the falling wire rod 2 and the outer periphery of the inner frame 16 changes sequentially, and furthermore, as described above, the receiving plate 11 descends according to the amount of wire storage, and the upper end of the wire storage rod 2 and the roller of the arm 5 change. 29 is kept constant and small, the falling point of the wire follows the movement trajectory of the tip of the arm 5, and as shown in Fig. 3, the wire falls in a fixed shape to the receiving plate 11 and is stored. . Therefore, it is expected that the line storage shape will be made more beautiful and the amount of accumulated radiation will be increased. Also,
The structure is simple because the swing of the arm 5 causes the wire to fall in a fixed shape and store the wire.

When winding is completed, the receiving plate 11 is lowered to the upper surface of the winding stand 13 and placed on the inner frame 16. Then, the support stand 12 is rotated and another take-up frame 7 is installed below the drum 1. In the winding frame 7 where winding is completed, the inner frame 16 is moved upward and the stored wire is taken out together with the inner frame 16. Note that the receiving plate 11 may be raised by rotating the screw shaft 9 before the next winding.

<Effects of the invention> As is clear from the above explanation, according to the invention, the wire guide arm is oscillated so that its oscillation period is slightly different from the rotation period of the take-up frame, and the wire rod receiving plate is It is configured to descend according to the amount of stored wire to keep the distance between the upper end of the stored wire and the tip of the arm constant and small, so that the falling point of the wire follows the movement trajectory of the tip of the arm. As a result, the wire falls in a fixed shape onto the receiving plate and is stored, which can be expected to improve the beauty of the stored wire shape and increase the amount of wire stacked. Also,
The swinging of the arm causes the wire to fall in a fixed shape and store the wire, so the structure is simple and has excellent effects.
