And a turn roller 6 arranged.

Conventionally, the bending device 3 has three first, second,
It comprises third bending rollers 3a to 3c, and the third bending roller 3c is provided so as to be movable and adjustable in the direction of arrow X in the figure. Then, the bending radius of the wire rod 1 is determined by the moving amount of the roller 3c.

Then, at the time of operation, as shown in FIG. 12, the wire 1 is first wound around the upper winding drum 2, once separated by the turn roller 6, and again wound around the lower winding drum 2 5 to 6 times.
Next, after being separated from the drum 2 by the bending device 3, the storage line bundle 7 is wound around the winding drum 2 again.

At this time, the wire rod 1 is arranged between the turn roller 6 and the winding drum 2 as shown in FIGS. 11 and 12, and the first bending roller 3a and the second bending roller 3b of the bending device 3 are connected.
After passing between the second bending roller 3b and the third bending roller 3c, the third bending roller 3c gives a ring shape, and then the winding drum 2 winds the winding drum 2. The wire bundle is taken and stored on the outer circumference to form a wire bundle 7.

It is provided in. Then, at the lowermost position of the lifter 82, the lifter arm 83 pivots downward to drop the stored wire bundle 11a.

Reference numeral 84 in the figure is a storage line bundle dropped from the lifter arm 83.
A carrier 85 for receiving and transporting 11a is a turntable 85 for mounting the carrier 84 and transporting it by turning.

In the wire rod winding machine having the above configuration, the winding operation is
It will be described with reference to the drawings and FIG.

First, as shown in FIG. 9 (a), the winding drum 12 winds the wire rod 11 sent from the feeding means, while rotating at high speed, by the upper flange 26 and the lower flange 27 of the winding block 23 for only one turn. After picking up, guide to the turn roller 17. The wire rod 11 is temporarily wound onto the winding block via the turn roller 17.
Winded up at 23. At this time, the wire rod 11 is the winding wire and the flange.
It is pushed down by 27 and is moved while being wound in an obliquely downward direction, is placed on the elevating arm 13, and is stored as a bundle of stored wires 11a. At this time, every time the winding amount of the wire rod from the optical sensor is confirmed, the rod 29 moves downward due to the rotation of the screw part by the motor, and the elevating arm 13 intermittently moves between 5 and 5.
It descends a fixed amount in 6 mm increments. Also, the bending device 1
The bending rollers 19a and 19b of 8 are perpendicular to the wire 11 and are in a non-contact state.

When a certain amount of the storage wire bundle 11a is stored on the elevating arm 13, the winding drum 12 is decelerated by the full length signal,
Switch to low speed rotation of m / min. At this time, the turning means 20 of the bending device 18 is actuated, and the bending roller 19a,
19b is rotated and brought into contact with the wire rod 11, and about 1 to 2 m before and after the cutting position of the wire rod 11 and a total of about 2 to 4 m is about 90% of the diameter of the winding drum 12.
Bend to the coil diameter. At the same time, the elevating arm 13 descends by a certain amount to the state shown in FIG. 9 (b).

Next, the positioning lever 15a projects obliquely upward from the opening 35. Then, the wire rod 11 is dropped by the positioning lever 15a into the storage wire bundle 11a, and the wire rod 11 diagonally crosses the cutting window 16. After the winding drum 12 makes one rotation, the wire storage levers 15b project at right angles from the respective openings 35 to hold the wire rod 11.

Then, the turning means 20 is used to bend the bending rollers 19a, 19a.
b rotates to be perpendicular to the wire rod 11 and maintains a non-contact state. And the winding drum 12 accelerates to 80 m / mi
After switching to medium speed rotation for a certain period of time, about 100 to 200 g of wire is stored on the positioning lever 15a and the wire storage lever 15b. In this way, the wire rod 11 has a certain amount of
After the wires are stored in a and 15b, the winding drum 12 stops at a fixed position.

At this time, the wire rod 11 wound afterwards is bent by the bending rollers 19a and 19b and is wound up first.
Since the wires are stored on the wire bundles 15a and 15b so as to cover the wire bundle 1, the wire rod 11 wound first is located at the innermost side of the wire bundle 11a.

The wire rod cutting tool 14 uses the pneumatic cylinder 63 to cut the cutting window 16
And the wire rod 11 diagonally crossing the cutting window 16 is cut. At the same time, the ends of the cut wire 11 are bent by the bending jig 65. This facilitates the removal of the wire end in the process.

After cutting, the elevating arm 13 descends as shown in FIG. 9 (c). When the elevating arm 13 descends to the lowermost end of the winding drum 12, the elevating arm 13 rotates inward of the winding drum 12 and the bundle of stored wires 11 a falls on the lifter arm 83.

Then, as shown in FIG. 9 (d), when the lifter 82 descends to the lowermost end and stops, the lifter arm 83 pivots downward and drops the stored wire bundle 11a into the carrier 84. afterwards,
The turntable 85 turns in a horizontal plane, the carrier 84 that has received the storage bundle 11a is conveyed, and the carrier 84 without the bundle attached is conveyed below the winding drum 12.

After that, the lifter 82 rises, and at the same time, the raising and lowering arm 13 rises to reach the upper limit of the groove 31 of the storage line block 24. At the same time, the lever 15a and the storage wire lever 15b are retracted into the respective openings 35, and the wire rod 11 temporarily stored is dropped onto the elevating arm 13. Then, the winding drum 12 starts to rotate again, and the wire rod 11
Is wound up (Fig. 9 (a)). At this time, the wire rod 11
Since the tip of is located on the innermost side of the storage bundle 11a,
It is possible to prevent the tip of the wire bundle 11a from jumping out and its variation.

The above operation is repeated, and the storage bundle 11a is successively transferred to the carrier 8
Place on the turntable 85 via 4.

In this way, the cut end of the wire 11 is bent by the bending device 18
The leading end of the wire rod 11 is made smaller than the coil diameter of the winding drum 12 by means of the winding wire, and the temporary storage wire of the intermediate wire receivers 15a and 15b makes it possible to wind the wire material more than the winding wire 11 wound afterwards. It will be located inside on the outer peripheral surface of the drum 12. Therefore, even when it is dropped on the elevating arm 13, it is located inside the stored wire bundle 11a,
Even if the winding drum 12 is subsequently rotated, the cutting end can be prevented from protruding outward due to the centrifugal force.

Further, a cutting window 16 is formed on the outer peripheral surface of the winding drum 12, and the cutting window 16 is arranged in advance so that the wire rod 11 crosses the cutting window 16 from the intermediate wire receivers 15a and 15b. Wire 11 is cut along the outer peripheral surface of the winding drum 12,
Is maintained at a position inside the stored wire bundle 11a, and the shape of the winding coil is not sloping, so that the work can be continued smoothly.

Further, since the bending device 18 has the pair of bending rollers 19a, 19b and the turning means 20, the bending rollers 19a, 19b during high speed rotation and stop.
Does not come into contact with the wire rod 11, and it is possible to prevent variations in the ring shape of the storage wire bundle 11a.

It should be noted that the present invention is not limited to the above embodiments, and it goes without saying that many modifications and changes can be made to the above embodiments within the scope of the present invention.

For example, in this embodiment, four cutting windows 16 and four elevating arms 13 are provided, but other numbers may be provided.

Furthermore, the wire rod cutting tool is not limited to the arm swing type, and for example, a linear movement type may be used.

<Effect of the Invention> As is apparent from the above description, according to claim 1 of the present invention, a bending device is provided at the starting end portion of the wire rod with a bending diameter smaller than the coil diameter of the winding drum, and the intermediate wire receiver is used for temporary storage. By winding the wire, it is possible to sequentially cover the outside of the starting end of the wire with a plurality of windings of the wire wound afterwards, so even when the wire is dropped onto the lifting arm, the starting end of the wire is dropped. The part can be maintained on the outer peripheral surface of the winding drum inside the bundle of stored wires.

Further, according to claim 2, since the cutting window on the outer peripheral surface of the winding drum is arranged at a position where the wire rod from the intermediate wire bridge crosses, the wire material having a ring shape is attached to the outer peripheral surface of the winding drum. The cutting end of the wire can be maintained at a position inside the storage bundle.

Further, according to claim 3, as a bending device,
Since a pair of bending rollers and a rotating means for rotating the bending rollers are provided, only the cut ends of the wire can be curved inward by rotating the bending rollers by the rotating means for a predetermined time, Among the wire rods on the wire receiver, the diameter of the cutting start end portion can be made smaller than the diameter of the wire rod wound thereafter. Then, it becomes easy to maintain the starting end portion of the wire rod at a position inside the storage bundle.

From the above, even after the wire rod is cut, even if the winding drum is rotated in a state where the wire rod is stored on the elevating arm, the starting end portion can be prevented from jumping outward due to centrifugal force. Therefore, it is not necessary to re-bundle the wire rods as a setup for the next work, and work efficiency is increased.

Further, according to claim 3, at the time of high speed rotation and at rest, etc.
The bending roller can be brought into a non-contact state with the wire rod except when necessary, and it is possible to prevent variations in the ring habit of the stored wire bundle, which has an excellent effect.
