Abstract

PROBLEM TO BE SOLVED: To enable a wire to be positively positioned in a wire supply path. SOLUTION: A centering unit is provided with a pair of opening and closing members 11 and 12 opposite to each other that interposies a wire supply path R. Each opening and closing member 11 and 12 can be displaced at an opening position for opening a wire supply path R and a closing position for closing it. The opening and closing members 11 and 12 is provided with guide parts 11D and 12D, respectively. The guide parts 11D and 12D surround the full circumference of the wire supply path R at a closing position and partition a surrounding space S1 in which a wire W is put aside on the wire supply part R. Thus, when the wire W is guided by means of the guide parts 11D and 12D, not only can the wire W be positively put aside on the wire supply path R, but also the wire W can be positively positioned on the wire supply path R to restrict positional displacement of the wire R.

427). In the above-mentioned prior art, a pair of restricting means arranged on the left and right of the electric wire feeding path to form a pair and restricting the positional deviation of the electric wire in the left-right direction, and a pair of restricting means arranged above the electric wire feeding path, A guide bar that regulates the positional deviation is provided.

[0004]

Since the above-mentioned restricting means and guide bar merely restrict the large deviation of the electric wire from the electric wire feeding path, the electric wire is precisely positioned in the electric wire feeding path. From the point of view, it worked only passively. Therefore, depending on the type of electric wire and the feeding speed, there is still a problem that the precise feeding accuracy cannot be maintained.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a centering unit capable of positively positioning an electric wire in an electric wire feeding path.

And a pair of opening / closing members that are displaceable to the opening / closing member, and that surrounds the entire circumference of the electric wire feeding path when the opening / closing member is in the closed posture, and defines an enclosed space that draws the electric wires onto the electric wire feeding path. In addition, the centering unit is provided with a guide portion that separates from each other to open the electric wire feeding path when the opening / closing member is in the open posture.

In the invention including this specific matter, the guide portion provided on the opening / closing member positions the wire by displacing the opening / closing member from the open position to the closed position in association with the wire feeding operation of the automatic terminal crimping device. regulate. At this time, the guide portion forms a surrounding space which is closed around the electric wire feeding path, and the electric wires in the surrounding space are positively moved to the electric wire feeding path. When the surrounding space is formed, that is, when the opening / closing member is changed from the open state to the closed state, the bevel surface formed on each opening / closing member is closed from the open state in the shape of a V on the guide side. The electric wire is pushed into the guide part side.

According to a second aspect of the present invention, in the centering unit according to the first aspect, the guide portion is
It is formed at the free end of each opening / closing member and is divided into meshing portions that overlap each other when in the closed state. In the invention including this specific matter, since the guide portions are defined by the meshing portions that overlap each other, the enclosed space defined by the guide portions can be set as narrow as possible when the opening / closing member is in the closed posture. .
