BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a linear body cutting device used, for example, to cut a sealed lead-in wire to a predetermined length.

0002

2. Description of the Related Art Conventionally, as shown in FIG. 9, this type of cutting device pulls out a linear body 1 wound around a spool (not shown) from the spool by a linear body drawing mechanism 2. The tip of the linear body 1 is chucked by a chuck mechanism 3, and the linear body 1 is cut into a predetermined length by a cutting mechanism 4 provided between the chuck mechanism 3 and the linear body drawing mechanism 2. ing.

The linear object feeding mechanism 2 is constructed by installing a clamp mechanism 5 on the top surface of a slider 6 for clamping the linear object 1. The tip is configured to be delivered to the chuck mechanism 3. The cutting mechanism 4 includes a fixed blade 7 and a movable blade 8, and the linear body 1 is cut by driving the movable blade 8 by a movable blade drive mechanism (not shown). In addition,
A clamp mechanism 9 is provided between the linear object drawing mechanism 2 and the cutting mechanism 4, which clamps the linear object 1 when the slider 6 retreats.

By the way, in the conventional cutting device configured as described above, the fixed blade 7 of the cutting mechanism 4 is plate-shaped, so that the fixed blade is attached to the cut linear body 1a as shown in FIG. The shape of No. 7 remains, which poses problems such as problems when welding the sealing wire to the outer lead or the inner lead.

Therefore, in order to solve this problem, as shown in FIG. 11, the fixed blade 7 and the movable blade 8 of the cutting mechanism 4 are
It has been considered that the blade is formed into a cylindrical shape, and the linear body 1 is cut by sliding the blade surface of the movable blade 8 on the blade surface of the fixed blade 7.

However, although the above-mentioned cutting device can cut the linear object 1 almost at right angles to the axial direction, the cutting mechanism 4 has the chuck mechanism 2 and the linear object drawing mechanism 3.
Since the tip of the linear body 1 held by the linear body drawing mechanism 2 was in contact with the rear end of the cut linear body 1a, the chuck mechanism 2 was There was a problem in that the linear body would be bent when trying to move it in the direction.

[0007]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned points, and its object is to cut a linear body almost at right angles to the axial direction, and to provide a chuck mechanism. An object of the present invention is to provide a cutting device for a linear body that can prevent the linear body from bending even when the linear body is moved in the radial direction of the linear body.

[0008]

[Means for Solving the Problems] In order to solve the above-mentioned problems, the present invention provides a linear body drawing mechanism that pulls out a linear body wound around a spool from the spool, and a linear body drawing mechanism that pulls out a linear body wound on a spool from the spool. a chuck mechanism that chucks the tip of the linear body pulled out from the spool; a clamp mechanism that is provided between the linear body drawing mechanism and the spool and clamping the linear body; and a clamp mechanism that clamps the linear body; a fixed blade provided in the linear body drawing mechanism and having an insertion hole through which the linear body is inserted; a movable blade provided in the linear body drawing mechanism and having an insertion hole through which the linear body is inserted; The movable blade driving means is provided to cut the linear body by sliding it on the blade surface of the blade.

[0009]

[Operation] In the present invention, the linear body is inserted into the insertion holes of the fixed blade and the movable blade, and the movable blade drive means slides the blade surface of the movable blade onto the blade surface of the fixed blade, thereby moving the linear body into the axis. It can be cut almost perpendicular to the direction. In addition, by providing a clamp mechanism for clamping the linear object between the linear object drawing mechanism and the spool, and providing a fixed blade and a movable blade in the linear object drawing mechanism, the fixed blade and movable blade are provided by the linear object drawing mechanism. The blade can be moved far back from the cutting position,
The cutting portion of the linear body can be exposed from the cutting mechanism consisting of a fixed blade and a movable blade. Therefore, after cutting the linear object, the fixed blade and the movable blade are moved back from the cutting position, and the linear object wound around the spool is pulled back.
Since a gap is formed between the linear body wound around the spool and the cut linear body, even if the chuck mechanism is moved in the radial direction of the linear body after cutting the linear body, the linear body It can prevent bending of the body.
