DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of manufacturing a wire-laden tag used for indicating a delivery destination of a wire.

[0002]

2. Description of the Related Art A method for automating the production of a tag with a wire is disclosed, for example, in JP-A-63-193827. It has a pair of elongated pipes arranged such that the holes of the pipes are on the same straight line, and has a wire torsion portion rotatable about an axis perpendicular to the straight line between the two pipes. When the hole is between the pair of pipes, the wire is passed through the pair of pipes and the hole of the tag, and from the state where the central portion of the wire passes through the hole of the tag, the tag and the wire are twisted. The wire is twisted and attached to the tag by rotating the wire torsion portion in a state where the wire portions are separated from each other and both ends of the wire are not completely removed from the holes of the pair of pipes.

[0003]

However, in this method, the wire is twisted with the hole of the tag as a fulcrum. If the strength of the wire is higher than that of the tag, the tag is broken by the wire and the wire is bent. There is a problem that you can not. The problem to be solved by the present invention is to enable the wire to be twisted without breaking the tag even when the strength of the wire is large, such as a large-diameter wire.

[0004]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention relates to a method for manufacturing a wire tag with a wire formed by providing a wire through a hole in a tag and twisting the wire. Take out the tags one by one, grasp the hole of the removed tag by hand at the position where the wire passes, and send out the wire wound in a coil shape as long as the tag is in the middle,
Pass the wire through the hole in the tag, bend the wire doubly around the hole in the tag, grab the bent wire end with a robot, wind the middle part of the wire around the wheel making mold to form a ring,
The robot grips the wheel and twists it to produce a wire tag.

[0005]

According to the above-mentioned means, a wire is passed through the tag in a fully automatic manner, a necessary loop is provided, and the wire is twisted to complete the tag. As soon as this tag is completed, it can be supplied to a steel bar binding machine by a robot and automatically attached to the steel bar and bound.

And the hands 7-1 and 7-2 have a tag 5
Notches 7-3 and 7-4 are provided so that the wire is sent through the hole 5-1 through which the wire passes. When the tag is inserted between the hands 7-1 and 7-2, the hands 7-1 and 7-2.
Is closed, and the tag is securely clamped. And hand 7
Is rotated by 90 degrees as shown in FIG. 2 and is sent out to the wire bending portion by the rotation / sending device 7-5.

(3) Wire-through bending section The wire-through bending section corresponds to the bending apparatus 15, 1 in FIG.
6. It is composed of holding devices 17 and 18, a gear for rotating them, and a rotation drive unit. Details of the wire bending device will be described with reference to FIGS. 4 shows a cross section XX of FIG. 3, and FIG. 5 shows a cross section YY of FIG. In these figures, a wire bending device 15 is a bending device 15 provided with a groove 15-6 for guiding a wire, and a pressing device 17 also provided with a wire guiding groove 17-6 drives the pressing device 17. Pin 15
It is configured to be attached at -9.

The holding device 17 is attached to the bending device 15 by a pin 15-9, and is attached away from the holding device 17 by a spring 15-7 to a cylinder 15-8.
Thereby, the pressing device 17 is pressed against the bending device 15. In the folding device 15, a folding device 16 having the same structure is provided symmetrically with the tag in the center. The folding device 15 is mounted on a gear 15-1 and is rotated by a driving device 15-3 via a gear 15-2. The folding device 16 is attached to a gear 16-1 and is rotated by a driving device 16-3 via a gear 16-2.

The wire 8 is fed by the feeding device 3 and the pressing device 17 is pressed against the bending device 15 so that the groove 1 is pressed.
It is sent through the folding device 15 along the line 5-6, and is sent along the groove 16-6 of the folding device 16 through the hole 5-1 of the tag 5. The wire 8 fed by the specified length is cut by the cutting machine 4. FIG. 4 shows a state in which the wire 8 is placed on the wire passing bent portion through the hole 5-1 of the tag 5.

From this state, as shown in FIG. 6, the bending device 15 is rotated about the hole 5-1 of the tag 5 by approximately 90 degrees as shown by an arrow through a gear 15-2 by a driving device 15-3. You. Similarly, the folding device 16 is also a driving device 16.
The tag 3 is rotated about the hole 5-1 of the tag 5 by approximately 90 degrees via the gear 16-2 as indicated by an arrow. The rotation of the folding devices 15 and 16 takes place simultaneously. Gears 15-1 and 16 to which folding devices 15 and 16 are attached
-1 is concentrically mounted, so hole 5 in tag 5
The bending devices 15 and 16 can rotate around the wire 1 to bend the wire 8.

(4) Wire Ring Forming Part FIG. 7 shows details of the wire ring forming part. In FIG. 7, the wire wheel forming unit includes a wheel forming die 30 and a robot 41. The ring forming process will be described with reference to FIGS. 7, 8, 9, and 10. In FIG. 7, the wire 8 is in a state of being folded in two at the hole 5-1 of the tag 5. At this point, the end of the wire is firmly gripped by the grip 41-1 of the hand 41 of the robot 40. Since the notches 15-5 and 16-5 are provided in the bending devices 15 and 16, the end of the wire 8 can be gripped by the robot hand.

After firmly holding the end of the wire with the robot hand 41, the pressing devices 17, 18 of the bending devices 15, 16 are used.
Is separated from the bending device by the cylinder 15-8 and the spring 15-7 described with reference to FIG. 5, and the bending devices 15, 16 and the pressing devices 17, 18
A gap is formed between the folding devices 15 and 16, and the folding devices 15 and 16 are rotated 90 degrees back to the original state by the rotating gears. At this time, since the wire has a gap between the bending devices 15 and 16 and the holding devices 17 and 18, the wire is held by the robot in FIG.
It remains in the state as shown in FIG. In the state shown in FIG.
Pushed up by -1. When the wheel mold 30 is pushed up and installed, the robot 40 moves the hand 41.
The wire 8 is wound around the wheel forming die 30 while the wire is gripped by the step (5), and the wire is wound around the wheel forming die 30 to form a ring as shown in FIG.

When the wire 8 is wound around the wheel forming die 30, the wire gripping hand 20 is moved upward by, for example, a cylinder 20-2 while the end of the wire 8 is gripped by the robot hand 41 of the robot 40. Grasping part 20-1
, Firmly grasp the intersection that has deviated from the wire 8. Then, the wheel forming mold 30 is lowered by a cylinder 30-1 or the like. At this time, as shown in FIG. 10, the ring forming die 30 is moved downward along the hole of the frame 19 so that the wire 8 formed in the ring easily comes out of the ring forming die 30. Then, the wire 8 held by the hand 41 of the robot 40 is removed. FIG. 9 shows a state in which the wire 8 is gripped by the wire gripping hand 20, the wheel forming mold 30 moves downward, and the robot 40 removes the wire 8 from the hand 41.

(5) Wire torsion part The wire torsion part is constituted by a robot. In FIG. 9, the wire 8 is formed into a loop and is held by the wire gripping hand 20. In this state, the hand 41 of the robot 40 firmly grasps the loop portion of the wire 8 so that the loop is sandwiched by the grasping section 40-1.

FIG. 11 shows a state in which the hand 41 of the robot 40 holds the wheel. With the robot hand 41 holding the wire 8 around, the robot 40 rotates the hand 41 as shown in FIG. As the robot 40, a multi-axis drive robot having the number of axes capable of performing such an operation is used. Rotation is performed by the necessary number of twists while holding the wire 8. When the necessary rotation is completed, the tag gripping hand 7 releases the gripping of the tag 5, and the wire gripping hand 20 also releases the gripping of the wire 8.
Is taken out of the device. The picked-up tag 5 is put on the bar bars arranged on a plane, then bound by the bar bar binding machine 50, and inserted into the bar bar bundle.
