Abstract

PROBLEM TO BE SOLVED: To require a wire to be simply led through a cylindrical body at the time of starting a work, and perform the work easily in a short time by forming a wire guide device out of the cylindrical body, regarding a wire guide device for guiding a wire to a sizing roller. SOLUTION: This wire guide device 2 is formed to have a cylindrical body, and the inner diameter of the cylindrical body is slightly larger than the outer diameter a wire. Also, an inner diameter part at a wire insertion end is formed as a taper 2D for allowing the easy insertion of the wire. When the wire guide device 2 formed out of the cylindrical body is used, the wire is delivered under contact with the inner surface of the cylindrical body, and guided to a sizing roller approximately in a linear state. Thus, the wire is simply required to be led through the cylindrical body at the start of a work, and the work can be done easily in a short time.

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to, for example, sending an electric wire to a measuring roller to measure it to a predetermined length, cutting it,
The present invention relates to a wire rod guiding device used in an automatic cutting machine or the like for crimping a terminal to the end of an electric wire cut afterwards.

2. Description of the Related Art In order to manufacture a wire harness or the like, first, an electric wire is sent to a measuring roller through a wire rod guiding device, the electric wire is measured to a predetermined length by the measuring roller, and the measuring wire is cut. A wire harness is manufactured by crimping a terminal to the end of the electric wire cut later to manufacture an electric wire with a terminal, and bundling a plurality of electric wires with a terminal.

As described above, first, the electric wire is sent to the measuring roller through the wire rod guiding device, and then the electric wire is measured to a predetermined length by the measuring roller, cut, and then the end of the cut electric wire. The work of crimping the terminal to the part is done by an automatic cutting machine.
It is done automatically.

As shown in FIG. 2, this automatic severing machine measures a wire rod guiding device 2 for guiding an electric wire 1 to a measuring roller 3 and an electric wire 1 passing through the wire rod guiding device 2 to a predetermined length. And a guide roller 4 for guiding the electric wire 1 that has passed through the measuring roller 3 in a predetermined direction. The electric wire that has passed through the guide roller 4 is cut and attached with terminals.

As shown in FIG. 3, a conventional wire rod guide device 2 has a plurality of small-diameter rollers 2C arranged in a zigzag pattern, and the plurality of small-diameter rollers 2C are arranged so that an electric wire 1 passes in a corrugated manner. Has been done. As shown in FIG. 2, two wire rod guide devices 2 are arranged in series, and the lateral guide device 2A in the preceding stage is arranged in a zigzag pattern so that the rotation axes of the plurality of small diameter rollers 2C are in the horizontal direction. In the vertical guide device 2B arranged in the rear stage, the rotary shafts of the plurality of small-diameter rollers 2C are rotated 90 ° from the horizontal direction and arranged in a zigzag pattern in the vertical direction.

The wire rod guide device 2 guides the wire rod 1 to the measuring roller 3 and also has a role as a wire rod straightening device for straightening the wire rod 1.

[0007]

However, as described above, in the conventional wire guide device 2, the small diameter rollers 2C are arranged in a staggered manner so that the electric wire 1 passes between the small diameter rollers 2C in a corrugated manner. Due to this structure, there is a problem that the work of passing the electric wire 1 between the small diameter rollers 2C at the start of the work is troublesome.

[0008]

Means for Solving the Problems As a result of various investigations for solving the above-mentioned problems, the present inventors have found that the wire does not have a large bending tendency and that the wire need not be realigned. It was Therefore, in the present invention, a cylindrical wire rod guide device is used instead of the wire rod guide device in which the small diameter rollers 2C are arranged in a staggered manner. That is, the present invention is a wire rod guide device for guiding a wire rod to a measuring roller, wherein the wire rod guide device is formed of a cylindrical body.

When the wire guide device is formed of a cylindrical body, the work can be carried out easily and in a short time because the electric wire only has to be passed through the cylindrical body at the start of the work.

DETAILED DESCRIPTION OF THE INVENTION The present invention will be described in detail below with reference to the drawings. FIG. 1 shows a wire rod guide device 2 used in the present invention.
The wire rod guide device 2 is formed in a cylindrical body. The inner diameter of the cylindrical body is formed to be slightly larger than the outer diameter of the electric wire. Further, the inner diameter portion on the wire insertion end side is formed in a tapered shape 2D to facilitate insertion of the wire 1.

A wire rod guide device 2 having such a cylindrical body.
Is used, for example, by removing the vertical guiding device 2B shown in FIG. 2 and arranging it at that position. In this case, the lateral guide device 2A is also removed.

A wire rod guide device 2 having such a cylindrical body.
When the wire is used, the electric wire 1 is sent while hitting the inner surface of the cylindrical body so that it becomes a substantially linear shape and is guided to the measuring roller.

[0013]

Example A wire guide device made of hard iron and having an inner diameter of 7 mm and a length of 270 mm was prepared. When an electric wire having a diameter of 2 mm was passed through this wire guide device and the electric wire was guided to a standard length roller, the electric wire became substantially straight and was guided to the measuring roller, and it was confirmed that there was no problem without realigning the electric wire. It was

The cylindrical body of the wire rod guide device 2 used in the present invention may be provided with a cut groove in the longitudinal direction thereof, and the electric wire may be inserted into the cylinder body by utilizing the cut groove. By providing such a cut groove, the work of passing the electric wire through the cylindrical body can be further facilitated. The shape of the kerfs is preferably linear or corrugated.
In addition, the cylindrical body of the wire guide device 2 used in the present invention,
This includes not only an ellipsoid but also a tapered cylindrical body having a tapered front end. Further, the present invention can be used not only as a guide device for electric wires but also as a guide device for various wire rods.

[0015]

As described above, since the wire guide device according to the present invention is a cylindrical body, it is only necessary to pass the electric wire through the cylindrical body at the start of the work. Therefore, the work can be performed easily and in a short time. It can be carried out.
