BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mark tube mounting apparatus for producing an electric wire with a mark tube used for wiring a switchboard or the like.

[0002]

2. Description of the Related Art An electric wire to be connected to a switchboard or the like is provided with a mark tube at an end of the electric wire for indicating a wiring destination to which the electric wire is connected so that the electric wire can be correctly connected to each device. As a mark tube mounting apparatus for producing such an electric wire with a mark tube, an apparatus for printing characters of a specific wiring destination and mounting a mark tube cut to a specific length to an electric wire cut to a specific length is known. is there. An example of such an apparatus is disclosed in JP-A-60-10510 . In order to mount a soft mark tube on an electric wire, the mark tube mounting apparatus is provided with a mark tube holder having a cylindrical mark tube storage chamber having an inner diameter slightly larger than the outer diameter of the mark tube in a wire conveyance path, and the holder includes: This is to temporarily hold the mark tube, transport the electric wire toward the hole of the held mark tube, insert it, and release the gripping state by the mark tube holder.

[0003] In this mark tube mounting apparatus, a mark tube is mounted on the front end side and the rear end side of the electric wire, respectively. The mark tube mounted on the rear end side of the electric wire is mounted first when the electric wire is conveyed. Since there is a danger that the wire will come off the wire if it deviates from the position, a bent portion is formed in the wire to prevent the mark tube from coming out of the wire.

[0004]

Although the bent portion 1c is formed in the electric wire 1, the mark tube accommodating chamber in the mark tube holder 3 during the transfer of the electric wire 1 with the mark tube 2 to the right in FIG. When the mark tube 2 is hooked on the step 3e between the wire guide 3c and the wire guide 3d, the mark tube 2 sometimes comes off the wire 1 beyond the bent portion 1c of the wire. It is an object to solve this problem.
