2. Description of the Related Art As a method for automating the production of a tag with a wire, for example, there is a method described in JP-A-63-193827. This is to attach a pair of long and narrow pipes arranged so that the holes of the pipes are on the same straight line, and have a wire twisting portion rotatable about an axis orthogonal to the straight line between both pipes, When the hole is between the pair of pipes, the wire is passed through the pair of pipes and the hole of the load tag, and the load tag and the wire twist from the state where the central portion of the wire penetrates the hole of the load tag. The wire is twisted and attached to the luggage tag by rotating the wire twisting portion in a state where both ends of the wire are not completely pulled out from the holes of the pair of pipes by separating the parts.

[0003]

However, in this method, since the wire is twisted around the hole of the tag as a fulcrum, if the wire is stronger than 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 if the wire has a large strength such as a wire having a large diameter.

[0004]

In order to solve the above-mentioned problems, the present invention has been stocked in a method of manufacturing a wire tag with wire formed by twisting the wire by providing a loop through the wire in the hole of the tag. Take out the luggage tags one by one, grasp the holes of the retrieved luggage tags with the hand at the position where the wire passes, and send the wire wound in a coil shape as long as the luggage tag comes to the center,
Pass the wire through the hole of the tag, double fold the wire around the hole of the tag, grab the bent wire end with a robot, wind the middle part of the wire around the ring making mold to form a ring,
A robot grabs the loop and twists it to produce a wire tag.

[0005]

The tag is completed by fully automatically passing the wire through the tag, providing a necessary ring and twisting the wire by the above means. Upon completion, this tag can be robotically supplied to a steel bar tying machine and automatically attached and tied in the steel bar.
