The overall structure of the wire strip device will be outlined with reference to FIG. 12. The wire W fed forward (downward in the drawing) by the wire feeding means 1 is cut by the cutting blade 2 and then the rear portion W1. The front end and the rear end of the front portion W2 are held by the electric wire holding means 3 and 4, respectively, and are conveyed by the conveying means 5 and 6 and face the strip blades 7 and 8, respectively.
Insulation debris stripped by the cooperation of the wire holding means 3 and 4 and the strip blades 7 and 8 is sucked and removed by a suction pipe connected to a vacuum means (not shown) and supplied with negative pressure. .
The front end of the rear portion W1 and the rear end of the front portion W2 from which the core wire is exposed are further transported by the transport means 5 and 6, respectively, and face the terminal crimping machines 11 and 12, and the terminals are crimped.

  At this time, in the conventional electric wire strip device shown in FIG. 12, the cutting blade 2 and the strip blades 7 and 8 are arranged in a line on an extending straight line perpendicular to the feeding direction of the electric wire W.

Therefore, the rear portion W1 and the front portion W2 of the electric wire W cut by the cutting blade 2 are moved in the front-rear direction and separated from the cutting blade 2 as shown by the arrow A in FIG. As shown by B, it is moved laterally so as to face the strip blades 7 and 8, respectively, and then moved back and forth as shown by an arrow C in FIG. It is necessary to insert.
Then, with the strip blades 7 and 8 cut into the insulation coating, when the rear part W1 and the front part W2 of the electric wire W are moved back and forth as indicated by the arrow D in FIG. 15, the insulation coatings H1 and H2 are respectively moved back and forth. Are stripped and sucked into the suction pipes 9 and 10 to be removed.

  That is, in the conventional wire strip device shown in FIG. 12, the movement amount in the front-rear direction of the rear portion W1 and the front portion W2 of the wire W is large, and the process time required for stripping the insulation coating at the end of the wire is reduced. It has become difficult to shorten.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a wire strip device that can solve the above-described problems of the prior art and reduce the process time required for stripping the insulation coating at the end of the wire.

Hand stage for solving the aforementioned problem,
A wire strip device that cuts the supplied wire and strips the insulation coating at the end of the cut wire to expose the core wire,
A cutting blade for cutting the electric wire;
A strip blade that cuts into the insulating coating at the end of the cut wire;
An electric wire moving means for moving the electric wire back and forth in the axial direction and moving the electric wire in a lateral direction between a position facing the cutting blade and a position facing the strip blade;
With
After the cutting blade cuts the electric wire, the electric wire moving means moves the electric wire in the axial direction so as to be separated from the cutting blade by a distance corresponding to a strip length, and then the electric wire is moved to the strip blade. When the strip blade of the electric wire is moved laterally to an opposing position, the strip blade in the longitudinal direction of the strip blade with respect to the cutting blade is aligned with the strip blade in the vertical direction. The position is determined.

That is, in the above-described electric wire strip device, the cutting blade and the strip blade are not aligned in the horizontal direction as in the conventional device, but the direction in which the electric wire is moved in order to remove the insulation coating at the end of the electric wire. It is arranged offset.
Thus, after the supplied electric wire is cut by the cutting blade, the electric wire is moved in the axial direction so as to be separated from the cutting blade by a distance corresponding to a desired strip length, and then the strip is moved from the position facing the cutting blade. When the end part of the wire is moved laterally to the position facing the blade, the part of the wire where the strip blade is cut coincides with the strip blade in the vertical direction. You can make incisions.
Therefore, since the terminal portion of the electric wire is moved laterally to the position facing the strip blade as in the conventional device, the step of moving the electric wire further in the axial direction toward the strip blade is unnecessary. The process time required for the strip operation can be shortened.

In the above-described wire strip device,
The cutting blade and the strip blade each have an upper blade and a lower blade that are driven by a blade driving means to contact and separate from each other in the vertical direction,
The blade driving means is
A first position in which the upper and lower blades of the cutting blade and the upper and lower blades of the strip blade are both spaced apart in the vertical direction;
The upper blade and the lower blade of the cutting blade intersect each other to cut the electric wire, but the upper blade and the lower blade of the strip blade are spaced apart in the vertical direction and can receive the end of the electric wire in the horizontal direction. And the position of
A third position where the upper blade and the lower blade of the cutting blade and the upper blade and the lower blade of the strip blade intersect each other, and the strip blade cuts into the insulating coating of the electric wire;

More specifically, at the first position, the upper blade and lower blade of the cutting blade and the upper blade and lower blade of the strip blade are both separated in the vertical direction, so that the electric wire is fed forward by a predetermined length. Can be paid.
In the second position, the upper blade and the lower blade of the cutting blade intersect each other to cut the electric wire, but the upper blade and the lower blade of the strip blade are separated in the vertical direction, so that the cut electric wire is used as the cutting blade. Even if it is moved laterally from the facing position to the position facing the strip blade, the end portion of the electric wire and the strip blade do not interfere with each other.
In the third position, the upper blade and the lower blade of the cutting blade intersect further deeply, and the upper blade and the lower blade of the strip blade intersect each other and bite into the insulation coating of the electric wire. The terminal insulation coating can be stripped off.
As a result, it is possible to proceed directly from the second position to the third position without returning from the second position to cut the electric wire to the first position, so that the vertical movement of the cutting blade and the strip blade is wasted. The movement time required for strip work can be shortened.

The tip of the suction tube is provided with an opening for receiving the distal end portion of the electric wire that moves laterally from a position facing the cutting blade to a position facing the strip blade inside the suction tube. It may be characterized by that .

That is, in the conventional apparatus, in order to insert the end of the electric wire into the suction tube, it is necessary to move the electric wire in the axial direction after making the end of the electric wire face the suction tube.
On the other hand, in the above-described strip device, when the end of the cut electric wire is moved in the lateral direction so as to face the strip blade, the end of the electric wire enters the inside through the opening provided in the suction tube. Does not need to be moved in the axial direction.
Thereby, the process time required for strip work can be shortened.

In the above-described wire strip device,
When stripped of insulation at the end of the wire, characterized by further comprising an opening closing means for closing the opening provided in the suction tube may be so.

That is, a negative pressure from a vacuum device is supplied to the suction pipe so as to suck the stripped pieces of insulating coating.
Therefore, if the opening provided in the tip portion of the suction tube is open, the suction force is reduced, and there is a possibility that the waste of the insulating coating cannot be sucked smoothly.
At this time, in the strip device described above, the opening of the suction tube is closed by the closing means when stripping the end of the electric wire, so that the suction force is not reduced and the insulating coating debris is reliably sucked and removed. can do.

In the above-described wire strip device,
The opening closure means, may be characterized in that in conjunction with the vertical movement of the strip blades a lid member for opening and closing the opening.

That is, when stripping the insulation coating at the end of the electric wire, the blade driving means operates to bring the upper blade and the lower blade of the strip blade closer to each other and cut into the insulation coating.
At this time, by fixing the lid member that moves up and down in conjunction with the strip blade to the strip blade or blade driving means, the opening of the suction tube can be opened and closed in conjunction with the strip operation.

Further, the wire strips apparatus described above, the opening closure means, may be characterized in that it is a cover member for opening and closing the opening in conjunction with the wire to move in the axial direction when the strip.

That is, when stripping the insulation coating at the end of the wire, the wire is moved in the axial direction when the strip blade is cut into the insulation coating.
