Description

本発明は、複数のワイヤが保持部材によって一体的に保持されたワイヤハーネスの被覆剥がし装置に関するものである。 The present invention relates to an apparatus for stripping a wire harness in which a plurality of wires are integrally held by a holding member.

従来、複数のワイヤの被覆層を同時に切断して剥がす被覆剥がし装置として、ワイヤの被覆層に切り込みを入れる刃を２つ設け、２つの刃の間に複数のワイヤを挟持して、ワイヤの被覆層を切断して剥がすものが提案されている（例えば、特許文献１参照）。 Conventionally, as a coating peeling device that cuts and peels a plurality of wire coating layers simultaneously, two blades for incising the wire coating layer are provided, and a plurality of wires are sandwiched between the two blades to cover the wires. There has been proposed one that cuts and peels off a layer (see, for example, Patent Document 1).

しかしながら、従来の被覆剥がし装置は、複数のワイヤが２列配置されるとともに各列毎に複数本配置されたワイヤハーネスの場合、全てのワイヤの被覆を同時に剥がすことができないため、各列毎に被覆層を切断して剥がす必要があった。すなわち、被覆剥がし作業を２回行う必要があった。 However, in the case of a wire harness in which a plurality of wires are arranged in two rows and a plurality of wires are arranged for each row, the conventional sheath peeling apparatus cannot peel off all the wires at the same time. It was necessary to cut and peel off the coating layer. That is, it was necessary to perform the coating peeling operation twice.

本発明は上記点に鑑みて、複数のワイヤが２列配置されるとともに各列毎に複数本配置されたワイヤハーネスの被覆層を剥がす際、１回の被覆剥がし作業で全てのワイヤの被覆を剥がすことができるようにすることを目的とする。 In the present invention, in view of the above points, when a plurality of wires are arranged in two rows and a coating layer of a plurality of wire harnesses arranged in each row is peeled off, the coating of all wires is performed by a single coating peeling operation. The purpose is to be able to peel off.

上記目的を達成するため、請求項１に記載の発明では、芯線を被覆層にて覆った複数のワイヤ（９２ａ、９２ｂ）が、２列配置されるとともに各列毎に複数本配置された状態で、保持部材（９１）によって一体的に保持された、ワイヤハーネスの被覆剥がし装置であって、第１列のワイヤ（９２ａ）と第２列のワイヤ（９２ｂ）との間に位置して、全てのワイヤ（９２ａ、９２ｂ）の被覆層に切り込みを入れる中央刃（１）と、第１列のワイヤ（９２ａ）と第２列のワイヤ（９２ｂ）の並び方向に沿って移動可能で、中央刃（１）側に移動したときに中央刃（１）との間に第１列のワイヤ（９２ａ）を挟持して第１列のワイヤ（９２ａ）の被覆層に切り込みを入れる第１可動刃（２）と、第１列のワイヤ（９２ａ）と第２列のワイヤ（９２ｂ）の並び方向に沿って移動可能で、中央刃（１）側に移動したときに中央刃（１）との間に第２列のワイヤ（９２ｂ）を挟持して第２列のワイヤ（９２ｂ）の被覆層に切り込みを入れる第２可動刃（３）とを備え、３個の刃（１〜３）によって全てのワイヤ（９２ａ、９２ｂ）が挟持された状態で、全てのワイヤ（９２ａ、９２ｂ）および保持部材（９１）と、３個の刃（１〜３）とが、相対的に遠ざかる向きに移動されることを特徴とする。 In order to achieve the above object, in the first aspect of the present invention, a plurality of wires (92a, 92b) whose core wires are covered with a coating layer are arranged in two rows and a plurality of wires are arranged in each row. Thus, the apparatus for stripping the wire harness, which is integrally held by the holding member (91), is located between the first row of wires (92a) and the second row of wires (92b), A central blade (1) for incising the covering layer of all the wires (92a, 92b), movable along the alignment direction of the first row of wires (92a) and the second row of wires (92b). The first movable blade that cuts the coating layer of the first row of wires (92a) by sandwiching the first row of wires (92a) between the central blade (1) when moved to the blade (1) side (2), the first row of wires (92a) and the second row of wires (92b) The second row of wires (92b) is sandwiched between the second blade (92b) and the central blade (1) when moved toward the central blade (1). And a second movable blade (3) for incising the coating layer of the wire (92a, 92b) with all the wires (92a, 92b) sandwiched between the three blades (1-3). ) And the holding member (91) and the three blades (1 to 3) are moved in a direction away from each other.

これによると、複数のワイヤ（９２ａ、９２ｂ）が２列配置されるとともに各列毎に複数本配置されたワイヤハーネスの被覆を剥がす際、１回の被覆剥がし作業で全てのワイヤ（９２ａ、９２ｂ）の被覆を剥がすことができる。 According to this, when a plurality of wires (92a, 92b) are arranged in two rows and a plurality of wire harnesses arranged in each row are peeled off, all the wires (92a, 92b) are removed by a single stripping operation. ) Can be removed.

Further, the central blade upper cutting blade portion 11 and the first movable blade cutting blade portion 21 face each other, and the central blade lower cutting blade portion 12 and the second movable blade cutting blade portion 31 face each other.

次に、被覆剥がし装置を用いてワイヤ９２の被覆層を剥がす手順について説明する。 Next, a procedure for removing the coating layer of the wire 92 using the coating peeling apparatus will be described.

まず、図１に示すように、第１可動刃２が上昇し且つ第２可動刃３が下降している状態で、ワーク９を３個の刃１〜３側に向かって（すなわち、図１（ｂ）の紙面左向きに）移動させて、ワイヤ９２の先端側を３個の刃１〜３の間に挿入する。 First, as shown in FIG. 1, with the first movable blade 2 raised and the second movable blade 3 lowered, the workpiece 9 is directed toward the three blades 1 to 3 (that is, FIG. 1). The wire 92 is moved between the three blades 1 to 3 and moved to the left in FIG.

より詳細には、中央刃上側切り込み刃部１１と第１可動刃切り込み刃部２１との間に、第１列のワイヤ９２ａの先端側を挿入し、中央刃下側切り込み刃部１２と第２可動刃切り込み刃部３１との間に、第２列のワイヤ９２ｂの先端側を挿入する。 More specifically, the distal end side of the first row of wires 92a is inserted between the central blade upper cutting blade portion 11 and the first movable blade cutting blade portion 21, and the central blade lower cutting blade portion 12 and the second cutting blade portion 12 are connected to the second cutting blade portion 12. Between the movable blade cutting blade portion 31, the distal end side of the second row of wires 92b is inserted.

続いて、図２に示すように、第１可動刃２を下降させて、すなわち、第１可動刃２を中央刃１側に移動させて、中央刃上側切り込み刃部１１と第１可動刃切り込み刃部２１との間に第１列のワイヤ９２ａを挟持し、第１列のワイヤ９２ａの被覆層に切り込みを入れる。 Subsequently, as shown in FIG. 2, the first movable blade 2 is lowered, that is, the first movable blade 2 is moved to the central blade 1 side, and the central blade upper cutting blade portion 11 and the first movable blade cutting are performed. The first row of wires 92a is sandwiched between the blade portions 21, and the covering layer of the first row of wires 92a is cut.

同様に、第２可動刃３を上昇させて、すなわち、第２可動刃３を中央刃１側に移動させて、中央刃下側切り込み刃部１２と第２可動刃切り込み刃部３１との間に第２列のワイヤ９２ｂを挟持し、第２列のワイヤ９２ｂの被覆層に切り込みを入れる。 Similarly, the second movable blade 3 is raised, that is, the second movable blade 3 is moved to the central blade 1 side, and the space between the central blade lower cutting blade portion 12 and the second movable blade cutting blade portion 31 is increased. The second row of wires 92b is sandwiched between the two and the coating layer of the second row of wires 92b is cut.

続いて、３個の刃１〜３によって全てのワイヤ９２が挟持された状態（図２の状態）で、図３に示すように、ワーク９を３個の刃１〜３側から遠ざかる向きに（すなわち、図３（ｂ）の紙面右向きに）移動させて、ワイヤ９２の先端側の被覆層をワイヤ９２から剥がす。なお、３個の刃１〜３によって全てのワイヤ９２が挟持された状態（図２の状態）で、３個の刃１〜３をワーク９から遠ざかる向きに（すなわち、図３（ｂ）の紙面左向きに）移動させて、ワイヤ９２の先端側の被覆層をワイヤ９２から剥がすようにしてもよい。 Subsequently, in a state where all the wires 92 are sandwiched by the three blades 1 to 3 (state shown in FIG. 2), as shown in FIG. 3, the workpiece 9 is moved away from the three blades 1 to 3 side. The cover layer on the tip side of the wire 92 is peeled off from the wire 92 by moving (that is, to the right in FIG. 3B). In a state where all the wires 92 are sandwiched by the three blades 1 to 3 (state shown in FIG. 2), the three blades 1 to 3 are moved away from the work 9 (that is, as shown in FIG. 3B). The coating layer on the tip side of the wire 92 may be peeled off from the wire 92 by moving the sheet 92 toward the left side of the drawing.

本実施形態によると、複数のワイヤ９２が２列配置されるとともに各列毎に複数本配置されたワイヤハーネスの被覆を剥がす際、１回の被覆剥がし作業で全てのワイヤ９２の被覆を剥がすことができる。 According to the present embodiment, when the plurality of wires 92 are arranged in two rows and the coating of the wire harness arranged in a plurality for each row is removed, the coating of all the wires 92 is removed by one coating removal operation. Can do.
