Next, the automatic winding operation will be described with reference to the time chart of FIG.

At the beginning of winding the wire, the elevating arm 3 is in the temporary storage line posture C at the uppermost portion of the storage line block 14, as shown in FIG. Then, the wire 1 sent from the supply side is once wound on the winding block 13 side, then passes through the turn roller 37 and the bending device 35, and is again wound up on the winding block 1 side.
3 and is pressed by the pressing roller 38, and the winding drum 2
Is set so as to be guided to the lower side of the drum 2 through the guide ring 72 close to Then, the guide ring 72 is brought close to the outer peripheral surface of the winding drum 2 to adjust the winding position of the wire 1.

In this state, the starting end side of the wire rod 1 maintains the coiling shape due to the tendency of the bending device 35, and is sent onto the elevating arm 3 as the drum 2 rotates, and the wire rod 1 is temporarily stored. It is supplied while sliding down on the elevating arm 3 having the line posture C, and is placed as the storage line bundle 1a.

At this time, as shown in FIG. 1, the starting end of the wire 1 is
The bending device 35 bends inwardly to form a ring shape, so that it is placed in contact with the elevating arm 3 and at the lowest end of the stored wire.

Then, the wire rods 1 that are sequentially placed as the winding drum 2 rotates are covered over the wire rods 1 that have been wound up earlier.

Then, the starting end portion of the wire rod 1 can be pressed from the outside by the wire rod 1 placed later.

Next, when the proximity switch 33 has detected from the number of rotations of the drum 2 that the winding is completed in this state, the motor 4a is operated and the elevating device 4 lowers the elevating arm 3. When the lifting arm 3 is lowered, the sliding piece 8 moves from the convex step portion 62 to the inner wall 6a. Then, the tip of the sliding piece 8 moves inward by the height of the convex step portion 62. The elevating arm 3 is rotated downward to be horizontal and maintained in the mounting posture A.

At this time, the wire 1 on the upper side shifts to the outside and disperses to some extent, but since the starting end of the wire 1 is pressed inward while contacting the elevating arm 3, even if the elevating arm 3 is in the mounting posture A, The spring back of the wire 1 can be prevented.

Thereafter, the elevating arm 3 descends every time the wire rod 1 is wound around the elevating arm 3 by a certain amount, and by repeating this descending operation, the wire rod 1 is stored on the elevating arm 3 as a storage wire bundle 1a as shown in FIG. To be When the wire rod 1 is in the fully wound state, the bending device 35 is operated, and the coil shape is maintained by the coil end having a smaller diameter. And
When the arm 3 descends to a predetermined position, the winding drum 2 is automatically stopped.

At the same time, the guide ring 72 moves in a direction away from the outer peripheral surface of the winding drum 2, pulls out the wire rod 1 to the cutting position, and the cutter 71 moves to the cutting position to cut the wire rod 1.

At this time, as shown in FIG. 9, the wire rod 1 is pressed by the pressing roller 38, and the cut end of the wire rod 1 is guided by the guide ring 7.
It remains to be left in 2.

Then, as shown in FIG. 9, after cutting, the elevating arm 3 further descends and falls vertically by the switching mechanism 17, and as a result, the placed wire rod bundle 1a falls onto the lifter arm 39. .

The wire bundle 1a thus taken out is shown in FIG.
Carriage 41 further set below it, like 0
It is transferred to and transported outside.

On the other hand, the elevating arm 3 is pulled up by the operation of the elevating device 4 after the wire is discharged. Then, as shown in FIGS. 1 and 2, when the elevating arm 3 reaches the uppermost part of the elevating guide groove 6, the roller 19 of the sliding piece 8 rolling on the inner wall 6 a of the elevating guide groove 6 causes the convex stepped portion 62. And is pushed downward (outside), and the elevating arm 3 rotates in the R direction around the horizontal shaft 15b. Then, the elevating arm 3 becomes the temporary storage line posture C. Then, the wire 1 may be wound again in order from the inside of the elevating arm 3.

As described above, in this embodiment, since the storage line posture switching means 61 for switching the elevating arm 3 between the temporary storage line posture C and the mounting posture A is provided, the starting end portion of the wire 1 is set at the start of winding. The storage wire bundle 1a can be pressed inward at the lowermost end of the storage wire bundle 1a in contact with the elevating arm 3, automatically preventing the cut end of the wire rod 1 from jumping outward, and stacking the storage wire bundle on the elevating arm. It is possible to easily prevent the shape from being disturbed.

Therefore, it is possible to prevent the wire rod 1 from being entangled in the subsequent process, and it is easy to form the wire bundle as a finished product. Therefore, it is possible to improve the work efficiency and to perform the manual work. It is possible to omit the step of aligning the stored wire bundles such as cutting the end portions of the wire rods, and it is possible to reduce the labor.

It is also possible to consider a proposal example in which a wire receiving device that is controlled to project and retract from the winding drum 2 is provided in association with the temporary storage wire of the wire rod 1 in association with the elevating operation of the elevating arm 3. Then, since the wire rod 1 can be temporarily stored with a simple structure by directly using the elevating arm 3, the number of parts can be further reduced as compared with the proposed example, and the cost can be reduced.

The starting end of the wire 1 slides on the inclined mounting piece 101 toward the winding drum 2 side, is positioned at the lowermost end, and is mounted on the innermost side of the elevating arm. Then, as the winding drum 2 rotates, the wire rod 1 is sequentially covered over the inclined mounting piece 101.

When a fixed amount is stored, the elevating device 4 lowers the elevating arm 3. Then, the short piece 104 of the tilted mounting piece 101 is released from the contact of the contact piece 105, and the tilted mounting piece 101 is rotated downward by its own weight, and the lifting arm 3 is moved.
And is buried in the buried groove 107. The wire rod 1 has a portion located outside, which varies to some extent, but the starting end portion remains in contact with the elevating arm 3 at the lowermost side of the inclined mounting piece 101, and therefore does not vary due to vibration. Then, the starting end portion is pressed against the outer wire rod 1 and placed on the upper surface of the elevating arm 3 while being positioned inside, and the wires are successively stored.

In this way, the inclined mounting piece 1 is attached to the elevating arm 3.
01 is rotatably provided, and the short piece 104 at one end of the inclined placement piece 101 is brought into contact with the contact piece 105 of the elevating guide groove 6, whereby the inclined placement piece 101 can be tilted.
