FIG. 10 is a front view of the state in which the first cover 60 is opened and the movable block 50 moves in the direction of the fixed block 40 in FIG. 9.

As shown in FIG. 5, the slider 32 holds the wire W while being located at the longest distance with the fixed block 40, and both the first cover 60 and the second cover 70 are closed. It is open.

At this time, the end of the wire (W) penetrates through the first through portion 42 and is seated only in the lower seating groove 41 of the fixed block 40, the fixed block 40 and the movable block 50 ) Are adjacent to each other.

In addition, the upper roller 92 of the second transfer unit 90 is spaced apart from the upper portion of the lower roller (91).

As the slider 32 moves in the direction of the fixed block 40 by the cylinder 33, the first cover 60 and the second cover 70 are opened. As described above, the wire W is disposed in the lower seating groove 41 of the fixed block 40 and the lower seating groove 51 of the movable block 50 while passing through the second through part 52. , The end of the wire (W) is arranged to move up to the upper portion of the lower roller (91).

That is, the wire W connects the fixed block 40 and the movable block 50.

This state is the same as the state shown in FIG.

The first distance sensor 34 measures the one-way movement distance of the slider 32, and when the controller 32 reaches the predetermined distance, the cylinder 33 passes through the cylinder 33. The movement of the slider 32 is stopped.

Thereafter, the control unit 100 rotates the first cover 60 and the second cover 70, as shown in FIG. 7, so that the first cover 60 and the second cover 70 are respectively Cover the upper portion of the fixed block 40 and the upper portion of the movable block 50.

This state is the same as that shown in FIGS. 3 and 4.

And the slider 32 which grasped the wire W releases the wire W. As shown in FIG.

In this state, the control unit 100 applies current to the fixed block 40 and the movable block 50 through the power supply unit.

Then, since the wire W is placed on both the fixed block 40 and the movable block 50, current flows through the movable block 50, the wire W, and the fixed block 40. .

At this time, since the wire W is pressed in a portion where the fixed block 40 and the movable block 50 are adjacent to each other, resistance is generated, and the wire W of the portion is heated to a high temperature by resistance heat and melted. Will be.

In this state, as shown in FIG. 8, the slider 32 moves in the direction of the guide part 20.

At this time, since the slider 32 does not hold the wire W, the slider 32 moves without transferring the wire W in the reverse direction.

When the slider 32 moves adjacent to the guide part 20, the second distance sensor 35 measures the amount of movement of the slider 32 in another direction, and the controller 100 controls the slider. When the 32 reaches a predetermined distance, the movement of the slider 32 is stopped through the cylinder 33.

When the slider 32 moves in a direction away from the fixed block 40, the first cover 60 covers an upper portion of the fixed block 40 and the wires W disposed therebetween. Since the wire W is held, the wire W maintains its state and position as it is.

After the slider 32 moves in a direction away from the fixed block 40, the movable block 50 is moved by the driving means in a direction away from the fixed block 40.

Then, the wires W between the fixed block 40 and the movable block 50 are better cut by the pulling force in the molten state.

In addition, the wire Wc cut to a predetermined length is moved in the direction of the second transfer part 90 together with the movable block 50, so that one end of the cut wire Wc is the upper portion of the lower roller 91. Is placed on.

At this time, the wire (W) is placed in a high temperature state by the resistance heat of the current, the air cooler 80 is filled with the wire (W) disposed between the fixed block 40 and the movable block (50) Air is blown to rapidly cool the wire W while simultaneously removing particles and the like on the cut surface.

Thereafter, as shown in FIG. 9, the slider 32 again holds the wire W. FIG.

In addition, the second cover 70 is reversely rotated to open the upper portion of the movable block 50, and at the same time, the upper roller 92 is lowered to the lower roller 91 on which the cut wire Wc is placed. do.

As the upper roller 92 descends, the cut wire Wc placed on the lower roller 91 is disposed between the lower roller 91 and the upper roller 92 while the lower roller 91 is disposed. It is separated from the upper surface of the movable block 50 by the rotation of and is transferred to the accommodating part 86 via the cradle 83.

At the same time or with a slight time difference, the controller 100 moves the movable block 50 in the direction of the fixed block 40 by the driving means, as shown in FIG. 60 is rotated to open the upper portion of the fixed block 40.

Then, the upper roller 92 is elevated in the upward direction of the lower roller 91.

Then, the fixed block 40 and the movable block 50 are placed adjacent to each other again, the first cover 60 and the second cover 70 is placed in an open state, the upper roller 92 Is raised, the state shown in FIG. 10 becomes the same as the state shown in FIG.

By repeatedly performing the above-described operation process, the wire (W) wound on the bobbin 15 is cut to a certain length by a resistance heat of the current is received in the accommodating portion (86).

As described above, the present invention can make the cutting surface neat by cutting the wire W using the current resistance heat, and can automatically transfer the wire W by the first transfer part 30 to build an unmanned system. Can be.
