Description

本発明は、金属薄板製の帯状ワークからリードフレームやコネクター、シャーシ類等の各種製品を連続的に生産するプレスラインやメッキライン、組立ライン等に設置され、ライン上を流れている先行の帯状ワークの終端に後行の帯状ワークの始端を突合せ溶接により接合し、或いはライン上を流れている帯状ワークの不良部分を切断除去し、不良部分を除去した帯状ワークの切断端面同士を突合せ溶接により接合し、帯状ワークをライン上へ連続的に供給できるようにした帯状ワークの突合せ接合装置に用いられるものであり、特に、リードフレームのようにピッチの異なるパイロット孔を夫々等間隔毎に形成した数種類の帯状ワークに対応することができ、各帯状ワークを幅方向に沿って正確に且つ容易に切断することができると共に、取扱性や作業性、経済性等に優れた帯状ワークの突合せ接合装置に用いる切断装置の改良に関するものである。   The present invention is a preceding strip that is installed in a press line, a plating line, an assembly line, etc. that continuously produces various products such as lead frames, connectors, chassis, etc. from a strip-shaped workpiece made of a thin metal plate, and flows on the line. Join the start of the following strip work to the end of the work by butt welding, or cut and remove the defective part of the strip work flowing on the line, and butt weld the cut end surfaces of the strip work from which the defective part has been removed It is used in a butt-joining apparatus for belt-shaped workpieces that can be joined and supplied continuously on the line, and in particular, pilot holes with different pitches, such as lead frames, are formed at equal intervals. It can correspond to several kinds of belt-like workpieces, and each belt-like workpiece can be cut accurately and easily along the width direction,扱性 and workability, to an improvement of the cutting device used in the butt joining device excellent belt-like work in the economy and the like.

一般に、銅や鉄、アルミ、ステンレス等から成る金属薄板製の帯状ワークを連続的に供給しながらリードフレームやコネクター、シャーシ類等を成形加工するプレスライン等に於いては、プレス装置内へ帯状ワークを挿入するための手数を省くため、ライン上に繰り出されている帯状ワークの終端に新しい帯状ワークの始端を突合せ溶接により接合し、新しい帯状ワークをライン上へ連続的に供給することが行われている。   Generally, in a press line that forms and processes lead frames, connectors, chassis, etc. while continuously supplying strip-shaped workpieces made of thin metal plates made of copper, iron, aluminum, stainless steel, etc. In order to save the labor for inserting the workpiece, the start of the new strip workpiece is joined to the end of the strip workpiece fed on the line by butt welding, and the new strip workpiece is continuously fed onto the line. It has been broken.

従来、帯状ワークを突合せ溶接により接合する装置としては、本件発明者等が先に開発した帯状金属薄板（帯状ワーク）の突合せ接合装置が知られている（例えば、特許文献１及び特許文献２参照）。   Conventionally, as a device for joining strip-shaped workpieces by butt welding, a butt-joining device for strip-shaped metal thin plates (band-shaped workpieces) previously developed by the present inventors has been known (see, for example, Patent Document 1 and Patent Document 2). ).

即ち、前記突合せ接合装置は、図示していないが、帯状ワークを支持載置するテーブルを備えたキャビネット本体と、帯状ワークを幅方向に沿って切断する切断装置と、帯状ワークの切断端面同士を突合せた状態でその突合せ部近傍を上下方向から挾持するクランプ機構と、帯状ワークの突合せ部を突合せ溶接する溶接用トーチを備えた溶接装置と、帯状ワークの溶接部を圧延して溶接部の厚みや組織を均一化する圧延装置等から構成されており、金属薄板製の帯状ワークの突合せ溶接を高精度で且つ高能率で行うことができる等の利点を有する。   That is, although the butt joining device is not shown, the cabinet body provided with a table for supporting and mounting the belt-like workpiece, the cutting device for cutting the belt-like workpiece along the width direction, and the cutting end surfaces of the belt-like workpiece are connected to each other. The clamp mechanism that holds the vicinity of the abutting portion in the up-down direction in the butted state, a welding device equipped with a welding torch that butt welds the abutting portion of the belt-like workpiece, and the thickness of the welded portion by rolling the welding portion of the belt-like workpiece And a rolling device that makes the structure uniform, and has an advantage that butt welding of a strip-shaped workpiece made of a thin metal plate can be performed with high accuracy and high efficiency.

ところで、プレス加工されて位置決め用のパイロット孔等を形成したリードフレーム等の帯状ワークは、引き続き別のプレス工程（フォーミングプレス、切断プレス）やボンディング工程（ダイボンディング、ワイヤボンディング）等に送り込まれて加工されている。この場合にも、帯状ワークをプレス工程やボンディング工程等へ連続的に供給できるように、上述した帯状ワークの突合せ接合装置を用いて先行の帯状ワークの終端に後行の帯状ワークの始端を突合せ溶接により接合することが行われている。   By the way, a strip-shaped work such as a lead frame that has been pressed to form a pilot hole for positioning, etc. is continuously sent to another press process (forming press, cutting press), bonding process (die bonding, wire bonding), etc. Has been processed. In this case as well, the starting end of the succeeding belt-shaped workpiece is butt-matched to the end of the preceding belt-shaped workpiece using the above-described belt-shaped workpiece butt-joining device so that the belt-shaped workpiece can be continuously supplied to the pressing process, bonding process, etc. Joining is performed by welding.

又、リードフレーム等の帯状ワークに於いては、プレス加工中にバリや傷、打痕跡、変形等の不良部分が発生することがある。特に、帯状ワークに部分的な変形が生じた場合には、位置決め用のパイロット孔のピッチに狂いが生じることになる。
このような状態の帯状ワークを別のプレス工程やボンディング工程等に送り込んで加工した場合、製品の品質に支障を来たすばかりでなく、金型が損傷する等の問題が発生する。然も、プレス工程中やボンディング工程中に帯状ワークの送りが不良となったり、位置決め精度が悪くなったりする等の問題も発生する。 Further, in a strip-shaped workpiece such as a lead frame, defective portions such as burrs, scratches, dent marks, and deformation may occur during press working. In particular, when a partial deformation occurs in the belt-like workpiece, the pitch of the positioning pilot holes is deviated.
When the belt-like workpiece in such a state is sent to another press process or bonding process and processed, not only will the product quality be impaired, but there will be problems such as damage to the mold. However, problems such as poor feeding of the strip-shaped workpiece and poor positioning accuracy during the pressing process and the bonding process also occur.

そのため、位置決め用のパイロット孔を形成した帯状ワークを加工するプレスライン等に於いては、帯状ワークの不良部分近傍を幅方向に沿って切断して不良部分を取り除き、帯状ワークの切断端面同士を突合せ溶接により接合してから、不良部分の無くなった帯状ワークを後続の加工工程等へ送るようにしている。この突合せ溶接にも、上述した帯状ワークの突合せ接合装置が使用されている。   For this reason, in a press line or the like that processes a strip-shaped workpiece in which positioning pilot holes are formed, the vicinity of the defective portion of the strip-shaped workpiece is cut along the width direction to remove the defective portion, and the cut end surfaces of the strip-shaped workpiece are separated from each other. After joining by butt welding, the belt-like workpiece having no defective portion is sent to the subsequent processing step or the like. The butt welding device for the band-shaped workpiece described above is also used for this butt welding.

ところが、上述した帯状ワークの突合せ接合装置を用いてリードフレームのように一旦加工された帯状ワークを突合せ溶接する場合には、様々な問題が生じることになる。
例えば、前記突合せ接合装置の切断装置を用いて位置決め用のパイロット孔を等間隔毎に形成した帯状ワークの終端部や始端部を幅方向に沿って切断した後、或いは帯状ワークの不良部分を切断加工により取り除いた後、二つの帯状ワークの切断端面同士を突合せ溶接により接合した場合、帯状ワークの突合せ部分のパイロット孔のピッチが狂うと云う問題が発生する。
何故なら、帯状ワークの終端部や始端部、不良部分を切断装置により切断する際に正確な位置で切断することが極めて困難であり、二つの帯状ワークの切断端面同士を突合せ溶接したときにパイロック孔のピッチにバラツキが生じるからである。その結果、この帯状ワークを後続の加工工程（ボンディング工程等）へ送り込むと、帯状ワークの送りが不良となったり、位置決め精度が悪くなったりする等、様々な不都合を生じることになる。 However, various problems arise when a belt-like workpiece once processed like a lead frame is butt welded by using the above-described belt-like workpiece butt joining apparatus.
For example, after cutting the end part and the start end part of the belt-like work in which the pilot holes for positioning are formed at equal intervals using the cutting device of the butt joining device along the width direction, or cutting the defective part of the belt-like work When the cut end surfaces of the two strip-shaped workpieces are joined by butt welding after being removed by machining, there arises a problem that the pitch of the pilot holes at the butt portion of the strip-shaped workpiece is out of order.
This is because it is extremely difficult to cut at the exact position when cutting the end, start and defective parts of the strip work with a cutting device. This is because the hole pitch varies. As a result, when this belt-like workpiece is fed into a subsequent processing step (bonding step or the like), various disadvantages such as poor feeding of the belt-like workpiece or poor positioning accuracy occur.

一方、本件発明者等は、上述した問題を解決する新しい帯状ワークの突合せ接合装置を開発し、これを特開２００４−２８３８６６号公報（特許文献３）として公開している。   On the other hand, the inventors of the present invention have developed a new butt-joining apparatus for belt-like workpieces that solves the above-described problems, and discloses this as Japanese Patent Application Laid-Open No. 2004-283866 (Patent Document 3).

即ち、前記帯状ワークの突合せ接合装置は、図１４に示す如く、位置決め用のパイロット孔を等間隔毎に形成した帯状ワークを幅方向に沿って切断する切断装置２０と、帯状ワークの切断端面同士を突合せた状態でその突合せ部近傍を上下方向から挾持する上部クランプ２１ａ及び下部クランプ２１ｂから成るクランプ機構２１と、帯状ワークの突合せ部を突合せ溶接する溶接用トーチを備えた溶接装置２２と、帯状ワークのパイロット孔のピッチと同一ピッチで配置されて帯状ワークの各パイロット孔に夫々着脱自在に嵌合される複数本の切断用位置決めピン２３ａから成る切断用位置決め機構２３と、同じく帯状ワークのパイロット孔のピッチと同一ピッチで配置されて帯状ワークの各パイロット孔に夫々着脱自在に嵌合される複数本の突合せ用位置決めピン２４ａから成る突合せ用位置決め機構２４等を備えており、帯状ワークの切断時にそのパイロット孔を切断用位置決め機構２３の切断用位置決めピン２３ａに嵌め込み、又、帯状ワークの突合せ時にそのパイロット孔を突合せ用位置決め機構２４の突合せ用位置決めピン２４ａに嵌め込むことによって、帯状ワークの位置決めを正確に行えるようになっている。   That is, as shown in FIG. 14, the belt-shaped workpiece butt-joining apparatus includes a cutting device 20 that cuts a belt-shaped workpiece in which positioning pilot holes are formed at equal intervals along the width direction, and the cutting end surfaces of the belt-shaped workpiece. A clamping mechanism 21 including an upper clamp 21a and a lower clamp 21b that holds the vicinity of the butted portion in the vertical direction, a welding device 22 having a welding torch for butt welding the butted portion of the band-like workpiece, and a belt-like shape A cutting positioning mechanism 23 comprising a plurality of cutting positioning pins 23a that are arranged at the same pitch as the pilot hole pitch of the workpiece and are detachably fitted to the pilot holes of the belt-like workpiece, and a pilot of the belt-like workpiece. A plurality of holes that are arranged at the same pitch as the holes and are detachably fitted to the pilot holes of the belt-like workpiece. A butt positioning mechanism 24 composed of a positioning pin 24a is provided, and the pilot hole is fitted into the cutting positioning pin 23a of the cutting positioning mechanism 23 when the strip-shaped workpiece is cut. By fitting the hole into the butt positioning pin 24a of the butt positioning mechanism 24, the belt-like workpiece can be positioned accurately.

その結果、この突合せ接合装置を用いれば、リードフレームのようにプレス加工等が施された帯状ワークであっても、切断装置２０に設けた切断用位置決め機構２３とクランプ機構２１に設けた突合せ用位置決め機構２４とによって、帯状ワークの切断と切断した帯状ワークの突合せ等を夫々正確に行うことができ、接合された帯状ワークもその寸法精度が高精度に保たれることになる。   As a result, if this butt joining device is used, even for a strip-like workpiece that has been subjected to press working or the like, such as a lead frame, the cutting positioning mechanism 23 provided in the cutting device 20 and the butt joining provided in the clamp mechanism 21 are used. The positioning mechanism 24 can accurately perform cutting of the strip-shaped workpiece and butting of the cut strip-shaped workpiece, and the dimensional accuracy of the bonded strip-shaped workpiece can be maintained with high accuracy.

然し乍ら、上述した帯状ワークの突合せ接合装置に於いても、未だ解決すべき問題点が残されており、その中でも切断装置２０部分に幾つかの問題がある。   However, there are still problems to be solved in the above-described belt-shaped workpiece butt joining apparatus, and among them, there are some problems in the cutting apparatus 20 portion.

即ち、従来の帯状ワークの突合せ接合装置に用いる切断装置２０は、図１５に示す如く、帯状ワークのパイロット孔のピッチと同一ピッチで配設された左右の下刃２５ａを備えた雌型２５と、雌型２５に形成した平面形状凸形の挿入穴２５ｂ内に上下動自在に挿入され、左右の下刃２５ａとの協働作用により帯状ワークの不良部分近傍を幅方向に沿って切断する左右の上刃２６ａを備えた雄型２６と、雄型２６を上下動させる流体圧シリンダ２７とから構成されており、切断処理する帯状ワークを左右の下刃２５ａと左右の上刃２６ａとの間に挿入し、雄型２６を流体圧シリンダ２７により上下動させることによって、左右の下刃２５ａと左右の上刃２６ａとで帯状ワークを幅方向に沿って切断するようになっている。   That is, as shown in FIG. 15, a cutting device 20 used in a conventional belt-shaped workpiece butt joining device includes a female die 25 having left and right lower blades 25a arranged at the same pitch as the pitch of pilot holes of the belt-shaped workpiece. The left and right sides are inserted in a flat convex insertion hole 25b formed in the female die 25 so as to be movable up and down, and cut the vicinity of the defective portion of the belt-like workpiece along the width direction by the cooperative action with the left and right lower blades 25a. It is composed of a male mold 26 having an upper blade 26a and a fluid pressure cylinder 27 for moving the male mold 26 up and down, and a band-shaped workpiece to be cut between the left and right lower blades 25a and the left and right upper blades 26a. Then, the belt 26 is cut along the width direction by the left and right lower blades 25a and the left and right upper blades 26a.

ところで、切断装置２０を長期間使用していると、特に、雌型２５の左右の下刃２５ａのエッジ部分が摩耗、損傷、変形したりすることがあり、この場合には、切れ味が悪くなって帯状ワークの切断を正確且つ良好に行えなくなり、左右の下刃２５ａを新しい下刃２５ａと交換しなければならない。
しかし、従来の切断装置２０に於いては、左右の下刃２５ａが雌型２５の挿入穴２５ｂの内周縁部に雌型２５と一体的に形成されているため、左右の下刃２５ａを交換するには、雌型２５全体を交換しなければならず、雌型２５の取り外しや取り付けに極めて手数が掛かるうえ、経済性に劣ると云う問題があった。特に、プレスラインやメッキライン等が複数列並んだ状態で帯状ワークが加工処理されている場合には、一台の突合せ接合装置を各ライン上へ移動させ、一台の突合せ接合装置で各ライン上の帯状ワークの切断や突合せ溶接を行うようにしているため、切断装置２０等の使用回数が大幅に増え、左右の下刃２５ａ等がより短期間で摩耗、損傷、変形したりすることになり、前記問題がより助長されることになる。 By the way, when the cutting device 20 is used for a long period of time, the edge portions of the left and right lower blades 25a of the female die 25 may be worn, damaged, or deformed. In this case, the sharpness becomes worse. Thus, the belt-shaped workpiece cannot be cut accurately and satisfactorily, and the left and right lower blades 25a must be replaced with new lower blades 25a.
However, in the conventional cutting device 20, since the left and right lower blades 25a are formed integrally with the female die 25 at the inner peripheral edge of the insertion hole 25b of the female die 25, the left and right lower blades 25a are replaced. In order to do so, the entire female mold 25 must be replaced, and the removal and attachment of the female mold 25 are very troublesome, and there is a problem that the cost is inferior. In particular, when strip-shaped workpieces are processed with multiple rows of press lines, plating lines, etc., one butt joining device is moved onto each line, and each line is moved with one butt joining device. Since the upper strip-shaped workpiece is cut and butt welded, the number of times the cutting device 20 and the like are used is greatly increased, and the left and right lower blades 25a are worn, damaged, and deformed in a shorter period of time. Thus, the problem is further promoted.

又、従来の切断装置２０に於いては、帯状ワークの切断時に雌型２５に設けた切断用位置決め機構２３の切断用位置決めピン２３ａに帯状ワークのパイロット孔を嵌め込んで位置決めするようにしているが、帯状ワークの切断後に帯状ワークを切断用位置決めピン２３ａから引き抜くときに極めて引き抜き難く、取扱性や作業性に劣ると云う問題があった。特に、切断用位置決め機構２３は、帯状ワークの位置決めを正確に行えるように帯状ワークのパイロット孔と切断用位置決め用ピン２３ａとの嵌め合い公差を小さく設定しているため、前記問題がより一層顕著に現れることになる。然も、厚みの極めて薄い帯状ワークを切断用位置決めピン２３ａから無理に引き抜いたりした場合、帯状ワークが部分的に変形してしまい、パイロット孔のピッチに狂いが生じると云う問題があった。この帯状ワークを後続の加工工程（ボンディング工程等）へ送り込んだ場合には、帯状ワークの送りが不良となったり、位置決め精度が悪くなったりする等、様々な不都合を生じることになる。   Further, in the conventional cutting device 20, when cutting the strip-shaped workpiece, the pilot hole of the strip-shaped workpiece is fitted into the cutting positioning pin 23a of the cutting positioning mechanism 23 provided in the female mold 25 for positioning. However, there is a problem that it is very difficult to pull out the strip-shaped workpiece from the positioning pin 23a for cutting after cutting the strip-shaped workpiece, resulting in poor handling and workability. In particular, the cutting positioning mechanism 23 has a small fitting tolerance between the pilot hole of the strip-shaped workpiece and the cutting positioning pin 23a so that the positioning of the strip-shaped workpiece can be accurately performed. Will appear. However, when the extremely thin belt-like workpiece is forcibly pulled out from the cutting positioning pin 23a, there is a problem that the belt-like workpiece is partially deformed and the pitch of the pilot holes is distorted. When this belt-like workpiece is fed to a subsequent processing step (bonding step or the like), various inconveniences such as poor feeding of the belt-like workpiece or poor positioning accuracy occur.

更に、従来の切断装置２０に於いては、雌型２５に設けた切断用位置決め機構２３の各切断用位置決めピン２３ａを全て同一ピッチで配置しているため、パイロット孔のピッチが全て同じ帯状ワークしか取り扱うことができないと云う問題があった。若し、パイロット孔のピッチが異なる別の帯状ワークを突合せ溶接する場合には、別の雌型２５と交換しなければならず、取り換えに極めて手数が掛かるうえ、別の雌型２５を用意しておかなければならないためにコストの高騰を招くと云う問題があった。
特開平１１−３４７７９２号公報 特開２００１−４７２８１号公報 特開２００４−２８３８６６号公報 Further, in the conventional cutting device 20, since the cutting positioning pins 23a of the cutting positioning mechanism 23 provided on the female die 25 are all arranged at the same pitch, the pilot holes all have the same pitch. There was a problem that it could only be handled. If another belt-like workpiece with different pilot hole pitches is to be butt welded, it must be replaced with another female mold 25, and it takes a lot of trouble to replace it, and another female mold 25 is prepared. There is a problem that the cost increases because it must be kept.

The lower position (the position shown in FIGS. 8 and 9) positioned below the upper end of the cutting positioning pin 13 ″, and the upper end of the cutting positioning pin 13 ″ are flush with the upper end of the cutting positioning pin 13 ″. The belt-shaped workpiece W can be moved up and down over the raised position (position shown in FIG. 12) where the belt-like workpiece W is pushed out from the cutting positioning pin 13 ″.
Note that the thickness of the left and right elevating plates 14 'is ½ of the depth of the recess 9b of the female main body 9, and the length of the left and right elevating plates 14' is the same as the length of the left and right pin positioning plates 13 '. Similarly, the widths of the left and right elevating plates 14 'are set to be the same as the widths of the left and right pin positioning plates 13'.

一方、駆動部１４″は、図８及び図９に示す如く、雌型本体９のピストン穴９ｃの大径部分にＯリング１４ｆを介して上下方向へ摺動自在に嵌合されたピストン１４ｂと、ピストン１４ｂの上面に連設され、ピストン穴９ｃの小径部分及びピン用位置決め板１３′に夫々挿通されて昇降プレート１４′にボルト１４ｇを介して連結されたロッド１４ｃと、ピストン穴９ｃの大径部分に配設され、ピストン１４ｂ及びロッド１４ｃを下方へ附勢して昇降プレート１４′を雌型本体９の凹部９ｂ内（下降位置）に位置させる復帰用の圧縮スプリング１４ｄと、ピストン穴９ｃの大径部分に螺着され、ピストン１４ｂ等を抜け止めすると共に、ピストン１４ｂの下面側へ作動流体（圧縮空気）を供給する作動流体用通路１４ｅ′を形成したプラグ１４ｅとから構成されており、作動流体供給源（図示省略）からの作動流体をピストン穴９ｃへ供給すると、ピストン１４ｂ、ロッド１４ｃ及び昇降プレート１４′が圧縮スプリング１４ｄの弾性力に抗して上昇し、昇降プレート１４′が切断用位置決めピン１３″の上端と面一又は切断用位置決めピン１３″の上端よりも上方位置になる上昇位置（図１２に示す位置）になり、又、作動流体の供給を停止すると、圧縮スプリング１４ｄの弾性力によりピストン１４ｂ、ロッド１４ｃ及び昇降プレート１４′が下降し、昇降プレート１４′が雌型本体９の凹部９ｂ内に収納されて切断用位置決めピン１３″の上端よりも下方に位置する下降位置（図８及び図９に示す位置）になるように制御されている。   On the other hand, as shown in FIG. 8 and FIG. 9, the drive unit 14 ″ includes a piston 14b fitted in a large diameter portion of the piston hole 9c of the female main body 9 through an O-ring 14f so as to be slidable in the vertical direction.

The plug 1 is screwed into the large-diameter portion to prevent the piston 14b and the like from coming off, and the working fluid passage 14e 'for supplying the working fluid (compressed air) to the lower surface side of the piston 14b is formed. When the working fluid from the working fluid supply source (not shown) is supplied to the piston hole 9c, the piston 14b, the rod 14c and the elevating plate 14 'rise against the elastic force of the compression spring 14d. Then, the elevating plate 14 ′ is in a raised position (position shown in FIG. 12) which is flush with the upper end of the cutting positioning pin 13 ″ or higher than the upper end of the cutting positioning pin 13 ″. When the supply is stopped, the piston 14b, the rod 14c and the elevating plate 14 'are lowered by the elastic force of the compression spring 14d, and the elevating plate 14' is accommodated in the recess 9b of the female main body 9, and the cutting positioning pin 13 " It is controlled so as to be a lowered position (position shown in FIGS. 8 and 9) located below the upper end.

前記ワーク押え機構１５は、図３及び図７に示す如く、雄型１１の突起部１１ｂの上面に立設した支持軸１５ａと、支持軸１５ａに上下動自在に支持され、雄型１１の突起部１１ｂを上方から覆う下方が開放されたアルミ合金等の金属材から成るボックス状の材料押え１５ｂと、支持軸１５ａの上端部と材料押え１５ｂとの間に介設され、材料押え１５ｂを下方へ附勢する弾性体１５ｃ（圧縮スプリング）とから構成されており、雄型１１が待機位置から切断位置へ下降したときに材料押え１５ｂの下端面が雌型本体９の上面に配置した帯状ワークＷの上面へ弾性的に当接し、材料押え１５ｂにより帯状ワークＷを雌型本体９の上面側へ押圧固定すると共に、左右の切断上刃１１ａ及び左右の切断下刃１０を覆い隠し、又、雄型１１が切断位置から待機位置へ上昇したときに材料押え１５ｂが弾性体１５ｃ（圧縮スプリング）により下方へ附勢されて左右の切断上刃１１ａを略覆い隠すようになっている。   As shown in FIGS. 3 and 7, the work presser mechanism 15 is supported by a support shaft 15 a erected on the upper surface of the protrusion 11 b of the male mold 11, and supported by the support shaft 15 a so as to be movable up and down. Covering the portion 11b from above, a box-shaped material retainer 15b made of a metal material such as an aluminum alloy whose bottom is open, and an upper end portion of the support shaft 15a and the material retainer 15b are interposed between the material retainer 15b and the lower portion. A belt-like workpiece in which the lower end surface of the material presser 15b is disposed on the upper surface of the female die main body 9 when the male die 11 is lowered from the standby position to the cutting position. Elastically abuts against the upper surface of W, presses and fixes the belt-like workpiece W to the upper surface side of the female main body 9 with the material presser 15b, covers the left and right cutting upper blades 11a and the left and right cutting lower blades 10; Male mold 11 is in cutting position Material pressing 15b when elevated to the standby position is adapted to conceal substantially cover the cutting upper blade 11a of the right and left are biased downward by an elastic body 15c (compression spring) from.

次に、上述した突合せ接合装置の切断装置１を用いてリードフレーム等の位置決め用のパイロット孔Ｗａを形成した先行の帯状ワークＷの終端部と同じく先行の帯状ワークＷと同じ形状の後行の帯状ワークＷの始端部とを幅方向に沿って切断する場合について説明する。   Next, the trailing end of the preceding belt-like workpiece W in which the pilot hole Wa for positioning of the lead frame or the like is formed using the cutting device 1 of the butt-joining device described above is the same as the preceding belt-like workpiece W. A case where the starting end portion of the belt-like workpiece W is cut along the width direction will be described.

プレスラインやメッキライン等のライン上を流れている先行の帯状ワークＷが残り少なくなると、先行の帯状ワークＷの終端部を切断用位置決め機構１３により位置決めし、この状態で先行の帯状ワークＷの終端部を切断上刃１１ａ及び切断下刃１０により幅方向に沿って一直線状に切断する。   When the preceding belt-like workpiece W flowing on a line such as a press line or a plating line is reduced, the end portion of the preceding belt-like workpiece W is positioned by the cutting positioning mechanism 13, and in this state, the end of the preceding belt-like workpiece W is reached. The part is cut in a straight line along the width direction by the cutting upper blade 11 a and the cutting lower blade 10.

即ち、雌型本体９と待機位置にある雄型１１との間に先行の帯状ワークＷの終端部を挿入し、先行の帯状ワークＷの終端部が右側の切断上刃１１ａと右側の切断下刃１０との間に位置するように帯状ワークＷのパイロット孔Ｗａの一部を右側の切断用位置決め機構１３の切断用位置決めピン１３″の何れかに嵌め込む（図１０参照）。これによって、先行の帯状ワークＷの終端部は、右側の切断用位置決め機構１３により雌型本体９上で位置決めされる。このとき、切断装置１は、待機位置にある雄型１１の左右の切断上刃１１ａがワーク押え機構１５の材料押え１５ｂにより略覆い隠されているため、作業員が左右の切断上刃１１ａで怪我をすると云うことがなく、位置決め作業を安全に行える。   That is, the end portion of the preceding belt-like workpiece W is inserted between the female die body 9 and the male die 11 at the standby position, and the end portion of the preceding belt-like workpiece W is cut at the right cutting upper blade 11a and the right cutting bottom. Part of the pilot hole Wa of the belt-like workpiece W is fitted into one of the cutting positioning pins 13 ″ of the right cutting positioning mechanism 13 so as to be positioned between the blade 10 (see FIG. 10). The end portion of the preceding belt-like workpiece W is positioned on the female die main body 9 by the right cutting positioning mechanism 13. At this time, the cutting device 1 has left and right cutting upper blades 11a of the male die 11 in the standby position. Is substantially covered and covered by the material presser 15b of the work presser mechanism 15, so that the operator can be safely injured without being injured by the left and right cutting upper blades 11a.

先行の帯状ワークＷの終端部が雌型本体９上で位置決めされたら、この状態で待機位置にある雄型１１を流体圧シリンダ１２により切断位置に下降させる（図１１参照）。そうすると、先行の帯状ワークＷの終端部が右側の切断上刃１１ａ及び右側の切断下刃１０により幅方向に沿って一直線状に切断される。このとき、ワーク押え機構１５の材料押え１５ｂの下端面が雌型本体９の上面に配置した帯状ワークＷの上面へ弾性的に当接し、材料押え１５ｂにより帯状ワークＷを雌型本体９の上面側へ押圧固定すると共に、材料押え１５ｂが左右の切断下刃１０及び左右の切断上刃１１ａを略覆い隠しているため、帯状ワークＷの切断をより安全に正確且つ確実に行えることになる。   When the terminal portion of the preceding belt-like workpiece W is positioned on the female die main body 9, the male die 11 at the standby position in this state is lowered to the cutting position by the fluid pressure cylinder 12 (see FIG. 11). If it does so, the termination | terminus part of the preceding strip | belt-shaped workpiece | work W will be cut | disconnected in a straight line form along the width direction with the cutting upper blade 11a on the right side, and the cutting lower blade 10 on the right side. At this time, the lower end surface of the material retainer 15b of the work retainer mechanism 15 is elastically brought into contact with the upper surface of the strip-shaped workpiece W disposed on the upper surface of the female mold body 9, and the strip-shaped workpiece W is brought into contact with the upper surface of the female mold body 9 by the material retainer 15b. Since the material presser 15b substantially covers and hides the left and right cutting lower blades 10 and the left and right cutting upper blades 11a, the belt-like workpiece W can be cut safely and accurately and reliably.

先行の帯状ワークＷの終端部が幅方向に沿って切断されると、右側の払出し機構１４を手動により又は自動により作動させる。そうすると、右側の払出し機構１４の昇降プレート１４′が下降位置から上昇位置へ上昇し、帯状ワークＷの終端部を水平姿勢で切断用位置決めピン１３″に沿って上方へ持ち上げ、切断用位置決めピン１３″から引き抜く（図１２参照）。このとき、昇降プレート１４′が、切断用位置決めピン１３″に嵌合された帯状ワークＷの裏面側に当接して帯状ワークＷの切断用位置決めピン１３″に嵌合された部分全域を押し上げているため、帯状ワークＷの複数のパイロット孔Ｗａを複数本の切断用位置決めピン１３″に嵌め込んでいても、帯状ワークＷを変形させることなく、切断用位置決めピン１３″から簡単且つ容易に引き抜くことができる。   When the end portion of the preceding belt-like workpiece W is cut along the width direction, the right-side dispensing mechanism 14 is operated manually or automatically. Then, the lifting plate 14 ′ of the right delivery mechanism 14 rises from the lowered position to the raised position, lifts the end portion of the belt-like workpiece W upward along the cutting positioning pins 13 ″ in a horizontal posture, and the cutting positioning pins 13 Pull out from ″ (see FIG. 12). At this time, the elevating plate 14 ′ is in contact with the back side of the strip-shaped workpiece W fitted to the cutting positioning pin 13 ″ and pushes up the entire area of the strip-shaped workpiece W fitted to the cutting positioning pin 13 ″. Therefore, even if the plurality of pilot holes Wa of the belt-like workpiece W are fitted into the plurality of cutting positioning pins 13 ", the belt-like workpiece W is easily and easily pulled out from the cutting positioning pins 13" without being deformed. be able to.

先行の帯状ワークＷの終端部が切断用位置決めピン１３″から引き抜かれたら、引き続き後行の帯状ワークＷの始端部を切断用位置決め機構１３により位置決めし、この状態で後行の帯状ワークＷの始端部を切断上刃１１ａ及び切断下刃１０により幅方向に沿って一直線状に切断する。   When the end portion of the preceding belt-like workpiece W is pulled out from the cutting positioning pin 13 ″, the starting end portion of the succeeding belt-like workpiece W is continuously positioned by the cutting positioning mechanism 13, and in this state, The starting end portion is cut in a straight line along the width direction by the cutting upper blade 11a and the cutting lower blade 10.

即ち、雌型本体９と待機位置にある雄型１１との間に後行の帯状ワークＷの始端部を挿入し、後行の帯状ワークＷの始端部が左側の切断上刃１１ａと左側の切断下刃１０との間に位置するように帯状ワークＷのパイロット孔Ｗａの一部を左側の切断用位置決め機構１３の切断用位置決めピン１３″の何れかに嵌め込む。これによって、帯状ワークＷの始端部は、左側の切断用位置決め機構１３により雌型本体９上で位置決めされる。このときも、切断装置１は、待機位置にある雄型１１の左右の切断上刃１１ａがワーク押え機構１５の材料押え１５ｂにより略覆い隠されているため、作業員が左右の切断上刃１１ａで怪我をすると云うことがなく、位置決め作業を安全に行える。   That is, the starting end portion of the succeeding belt-like workpiece W is inserted between the female die body 9 and the male die 11 at the standby position, and the starting end portion of the succeeding belt-like workpiece W is located on the left cutting upper blade 11a and the left hand side. A part of the pilot hole Wa of the strip-shaped workpiece W is fitted into any one of the cutting positioning pins 13 ″ of the left-side cutting positioning mechanism 13 so as to be positioned between the lower cutting blade 10 and the strip-shaped workpiece W. Is positioned on the female die body 9 by the left cutting positioning mechanism 13. Also at this time, the cutting device 1 has the left and right cutting upper blades 11a of the male die 11 at the standby position as the work holding mechanism. Since it is substantially covered by the 15 material pressers 15b, the operator can be safely positioned without any injury from the left and right cutting upper blades 11a.

後行の帯状ワークＷの始端部が雌型本体９上で位置決めされたら、この状態で待機位置にある雄型１１を流体圧シリンダ１２により切断位置に下降させる。そうすると、後行の帯状ワークＷの始端部が左側の切断上刃１１ａ及び左側の切断下刃１０により幅方向に沿って一直線状に切断される。このときも、ワーク押え機構１５の材料押え１５ｂの下端面が雌型本体９の上面に配置した帯状ワークＷの上面へ弾性的に当接し、材料押え１５ｂにより帯状ワークＷを雌型本体９の上面側へ押圧固定すると共に、材料押え１５ｂが左右の切断下刃１０及び左右の切断上刃１１ａを略覆い隠しているため、帯状ワークＷの切断をより安全に正確且つ確実に行えることになる。   When the starting end of the succeeding belt-like workpiece W is positioned on the female die body 9, the male die 11 at the standby position is lowered to the cutting position by the fluid pressure cylinder 12 in this state. Then, the starting end portion of the succeeding belt-like workpiece W is cut in a straight line along the width direction by the left cutting upper blade 11a and the left cutting lower blade 10. Also at this time, the lower end surface of the material presser 15b of the work presser mechanism 15 is elastically brought into contact with the upper surface of the strip-shaped workpiece W arranged on the upper surface of the female mold main body 9, and the band presser W is held by the material presser 15b of the female mold main body 9. While pressing and fixing to the upper surface side, the material presser 15b substantially covers and hides the left and right cutting lower blades 10 and the left and right cutting upper blades 11a, so that the strip-shaped workpiece W can be cut more safely and accurately. .

後行の帯状ワークＷの始端部が幅方向に沿って切断されると、左側の払出し機構１４を手動により又は自動により作動させる。そうすると、左側の払出し機構１４の昇降プレート１４′が下降位置から上昇位置へ上昇し、後行の帯状ワークＷの始端部を水平姿勢で切断用位置決めピン１３″に沿って上方へ持ち上げ、切断用位置決めピン１３″から引き抜く。このとき、昇降プレート１４′が、切断用位置決めピン１３″に嵌合された帯状ワークＷの裏面側に当接して帯状ワークＷの切断用位置決めピン１３″に嵌合された部分全域を押し上げているため、帯状ワークＷの複数のパイロット孔Ｗａを複数本の切断用位置決めピン１３″に嵌め込んでいても、帯状ワークＷを変形させることなく、切断用位置決めピン１３″から簡単且つ容易に引き抜くことができる。   When the starting end portion of the succeeding belt-like workpiece W is cut along the width direction, the left-side dispensing mechanism 14 is operated manually or automatically. Then, the raising / lowering plate 14 'of the left paying mechanism 14 is raised from the lowered position to the raised position, and the starting end portion of the succeeding belt-like workpiece W is lifted upward along the cutting positioning pins 13 "in a horizontal posture, for cutting. Pull out from the positioning pin 13 ″. At this time, the elevating plate 14 ′ is in contact with the back side of the strip-shaped workpiece W fitted to the cutting positioning pin 13 ″ and pushes up the entire area of the strip-shaped workpiece W fitted to the cutting positioning pin 13 ″.
