Apparatus and method for making electric wire for harness

An apparatus for making an electric wire for a harness, said apparatus including a wire cutter for cutting a supplied wire to form said electric wire of a predetermined length, said apparatus comprising:

• a sensor positioned upstream of said wire cutter in a supply direction of said supplied wire for detecting a portion to be removed from said supplied wire and to output a detection signal based thereon;
• a position element for specifying the position of said portion based on said detection signal;
• a wire distinguisher for determining the position of said portion based on said detection signal and information as to the length of said electric wire,
• a discriminator for differentiating between said electric wire and wire containing said portion cut from said supplied wire based on information determined by said wire distinguisher.

An apparatus for making an electric wire for a harness, said apparatus including a wire cutter for cutting a supplied wire to form said electric wire of a predetermined length, said apparatus comprising:

• a sensor positioned upstream of said wire cutter in a supply direction of said supplied wire for detecting a portion to be removed from said supplied wire and to output a detection signal based thereon;
• a position element for specifying the position of said portion based on said detection signal;
• a wire distinguisher for determining the position of said portion based on said detection signal and information as to the length of said electric wire,
• said position element indicating the position of said portion relative to a reference position at a time, said wire distinguisher including
• a first arithmetic element for calculating in which said electric wire to be formed, said portion is located at said time after detection of said portion by said sensor based on a position of said portion, a length of said electric wire, and a distance from said reference position to a cutting position of said wire cutter,
• a second arithmetic element for determining a distance from a front end of said electric wire, having said portion, to the position of said portion, and
• a removal element for determining a section, containing said portion, of said supplied wire to be removed based on said distance.

A method of making an electric wire for a harness, said method including cutting a supplied wire at a predetermined cut position to form said electric wire of a predetermined length, said method comprising

• detecting a portion to be removed from said supplied wire at a point upstream of said cut position in a supply direction of said supplied wire;
• determining the position of said portion;
• and
• specifying a removal section of said supplied wire having said portion based on the position of said portion relative to a reference position at a time, and the length of said electric wire,
• said specifying comprising calculating in which said electric wire to be formed is located at said time after detection of said portion based on the position of said portion, the length of said harness electric wire, and a distance from said reference position to said cut position,
• determining a distance from a front end of said electric wire to said portion and
• specifying said removal section on the basis of said distance.
