Description

本発明は、廃棄物等を束ねて所望の大きさに切断できる切断装置に関する。   The present invention relates to a cutting apparatus capable of bundling wastes or the like and cutting them into a desired size.

被切断物を通過させる開口部の下縁に固定刃が設けられたフレームと、フレームに昇降自在に案内されるスライダの下縁に設けられた可動刃と、被切断物を開口部の付近で下方に押える押圧駆動手段とを備える切断装置が、下記の特許文献に開示されている。
特開平７−１６４３７７号公報 A frame provided with a fixed blade at the lower edge of the opening through which the workpiece is passed, a movable blade provided at the lower edge of the slider guided so as to be raised and lowered by the frame, and the workpiece to be cut in the vicinity of the opening. A cutting device provided with a pressing drive means for pressing downward is disclosed in the following patent document.
JP 7-164377 A

図９に示すように、従来例の切断装置１００に適用されている可動刃６０は、幅方向の一端６０２から他端６０３まで直線状にエッジ６０４が傾斜した形状である。符号４０
はフレームを指し、符号９０は、被切断物１４を可動刃６０の一端６０２へ向けて押付ける幅寄せ手段を指している。 As shown in FIG. 9, the movable blade 60 applied to the conventional cutting device 100 has a shape in which the edge 604 is inclined linearly from one end 602 to the other end 603 in the width direction. Reference 40
Indicates a frame, and reference numeral 90 indicates a width adjusting means for pressing the workpiece 14 toward one end 602 of the movable blade 60.

図に表れていないフィダーにて紙面に直角な方向へ搬送される被切断物１４が、開口部２０を通過するところで、スライダ５０が可動刃６０と共に下降する。この行程で、可動刃６０の一端６０２付近のエッジ６０４が被切断物に切れ込み、更に可動刃６０の他端６０３付近のエッジ６０４が被切断物１４の下方へ通り抜けるには、可動刃６０が下降するストロークを少なくとも寸法線Ｓｈで表した長さに設定しなければならない。被切断物１４の切断を繰り返す毎に、可動刃６０を上昇させるストロークについても同様である。このため、切断装置１００の全高を低くすることが妨げられる。   When the workpiece 14 conveyed in a direction perpendicular to the paper surface by a feeder not shown in the drawing passes through the opening 20, the slider 50 moves down together with the movable blade 60. In this process, the edge 604 near one end 602 of the movable blade 60 cuts into the workpiece, and the edge 604 near the other end 603 of the movable blade 60 passes below the workpiece 14 so that the movable blade 60 is lowered. The stroke to be performed must be set to at least the length represented by the dimension line Sh. The same applies to the stroke for raising the movable blade 60 each time the cutting of the workpiece 14 is repeated. This prevents the overall height of the cutting device 100 from being lowered.

また、従来例の可動刃６０は、そのエッジ６０４の一端６０２から他端６０３までの全体と、固定刃３０のエッジ３０１の全体との間に被切断物１４を挟むことによって被切断物１４を切断を行うものである。固定刃３０又は可動刃６０に、磨耗又は欠損する等の不具合が起こった場合、これらを交換する必要に迫られる。このため、上記の不具合が起こる度に、切断装置１００を休止させることは避けられない。   Further, the movable blade 60 of the conventional example sandwiches the workpiece 14 by sandwiching the workpiece 14 between the whole from one end 602 to the other end 603 of the edge 604 and the whole edge 301 of the fixed blade 30. Cutting is performed. When troubles such as wear or chipping occur in the fixed blade 30 or the movable blade 60, it is necessary to replace them. For this reason, it is inevitable that the cutting device 100 is paused each time the above-described problem occurs.

そこで、本発明の目的とするところは、可動刃が昇降するストロークを短くでき、また大掛かりなメンテナンスの回数を減らすことのできる切断装置を提供することにある。   Accordingly, an object of the present invention is to provide a cutting device that can shorten the stroke in which the movable blade moves up and down and can reduce the number of large-scale maintenance.

本発明に係る切断装置は、フィーダにて搬送される被切断物が通過する開口部の下縁に、前記開口部の幅方向に延びる固定刃が設けられたフレームと、前記フレームに昇降自在に案内されるスライダの下縁に、前記固定刃に対向するよう設けられた可動刃と、前記被切断物を前記開口部の付近で下方に押える押圧駆動手段と、を備える切断装置において、前記可動刃が、互いに前記幅方向に隔たる両端を有し、前記両端から前記幅方向の内方へ向ってエッジが傾斜した山形であることを特徴とする。   The cutting device according to the present invention includes a frame in which a fixed blade extending in the width direction of the opening is provided at a lower edge of the opening through which an object to be cut conveyed by the feeder passes, and the frame can be moved up and down freely. In the cutting apparatus, comprising: a movable blade provided on a lower edge of the guided slider so as to face the fixed blade; and pressing drive means for pressing the object to be cut downward in the vicinity of the opening. The blade has a mountain shape having both ends spaced apart from each other in the width direction, and an edge inclined from the both ends toward the inside in the width direction.

更に、本発明に係る切断装置は、互いに前記幅方向に隔たり前記開口部の両側に配置され、相対向する作動部をそれぞれ進退させる一対の幅寄せ駆動手段を備え、前記一対の幅寄せ駆動手段のうち一の幅寄せ駆動手段が、その作動部を後退位置で停止させた状態で、前記一対の幅寄せ駆動手段のうち他の幅寄せ駆動手段が、その作動部を前進させることにより、前記被切断物を、前記幅方向の一方に寄せることを特徴とする。   Furthermore, the cutting device according to the present invention includes a pair of width-shifting drive units that are arranged on both sides of the opening and spaced apart from each other in the width direction, and that respectively move the opposing working portions forward and backward, respectively, With one of the width-shifting driving means stopping the operating portion at the retracted position, the other width-shifting driving means of the pair of width-shifting driving means advances the operating portion, thereby The workpiece is brought close to one side in the width direction.

更に、本発明に係る切断装置は、前記スライダが下降する行程で、前記幅方向の一方に寄せられた前記被切断物が、前記前記可動刃の両端のうちの一端から前記幅方向の内方へ向って傾斜するエッジと、前記固定刃との間に挟まれ切断されることを特徴とする。   Further, in the cutting device according to the present invention, in the stroke in which the slider descends, the object to be cut brought to one side in the width direction is inward in the width direction from one end of the both ends of the movable blade. It is characterized by being sandwiched and cut between an edge inclined toward the top and the fixed blade.

本発明に係る切断装置の可動刃は、その幅方向の両端から内方へ向って傾斜する山形であるため、被切断物を切断する毎に可動刃を昇降させる上下方向のストロークが比較的短く、スライダを開口部の上方へ案内する高さを抑えらる。従って、当該切断装置の全高を抑えることができる。   Since the movable blade of the cutting device according to the present invention has a mountain shape that inclines inward from both ends in the width direction, the vertical stroke for raising and lowering the movable blade every time the workpiece is cut is relatively short. The height for guiding the slider to above the opening is suppressed. Therefore, the overall height of the cutting device can be suppressed.

しかも、本発明に係る切断装置の可動刃は、その両端のうちの一端から幅方向の内方へ向って傾斜するエッジと、可動刃の両端のうちの他端から幅方向の内方へ向って傾斜するエッジとを適宜に使い分けることができる。即ち、一の幅寄せ駆動手段がその作動部を後退位置で停止させた状態で、他の幅寄せ駆動手段がその作動部を前進させることにより、被切断物を幅方向の一方に寄せることができる。更にスライダが下降すると、この行程で、可動刃の両端のうちの一端から幅方向の内方へ向って傾斜するエッジ、と固定刃との間に、幅方向の一方に寄せられた被切断物を挟み、この被切断物を切断することができる。   In addition, the movable blade of the cutting device according to the present invention has an edge inclined inward in the width direction from one end of both ends thereof, and inward in the width direction from the other end of both ends of the movable blade. It is possible to properly use the inclined edge. In other words, in a state where one width-shifting drive means stops its operating part at the retracted position, another width-shifting drive means moves the operating part forward so that the object to be cut can be brought close to one side in the width direction. it can. When the slider is further lowered, in this process, the object to be cut toward one side in the width direction between the edge that inclines inward in the width direction from one end of the movable blade and the fixed blade. The object to be cut can be cut.

ここで、一の幅寄せ駆動手段と他の幅寄せ駆動手段とは相対的な呼称であり、一対の幅寄せ駆動手段のそれぞれの作動部を進退させる向きを逆にすれば、被切断物を幅方向の一方の反対側（以下で「幅方向の他方」と記す。）に寄せるこができる。   Here, one width-shifting drive unit and the other width-shifting drive unit are relative names, and if the direction in which each operating portion of the pair of width-shifting drive units is advanced and retracted is reversed, the object to be cut is It is possible to approach one side in the width direction (hereinafter referred to as “the other in the width direction”).

以上の動作が所定の期間繰り返されると、可動刃の両端のうちの一端から幅方向の内方へ向って傾斜するエッジが徐々に磨耗し又は欠損することがある。また、固定刃についても、可動刃に対応する箇所で磨耗又は欠損が生じることがある。このような不具合が起こる時期を見計らって、被切断物を幅方向の他方に寄せると、上記のようにスライダが下降する行程で、可動刃の両端のうちの他端から幅方向の内方へ向って傾斜するエッジと、固定刃との間に、幅方向の他方に寄せられた被切断物を挟み、被切断物を切断することができる。   When the above operation is repeated for a predetermined period, an edge inclined inward in the width direction from one end of both ends of the movable blade may be gradually worn or missing. In addition, the fixed blade may be worn or chipped at a position corresponding to the movable blade. In anticipation of the time when such a failure occurs, when the work piece is moved to the other side in the width direction, the slider descends as described above, and the other end of the movable blades goes inward in the width direction. The object to be cut brought close to the other in the width direction can be sandwiched between the edge inclined toward the fixed blade and the fixed blade, and the object to be cut can be cut.

従って、本発明に係る切断装置によれば、可動刃と固定刃の一部分を使用して被切断物を切断する間、可動刃と固定刃の他の部分を使用しなくて済むので、可動刃と固定刃の一部分が磨耗し又は欠損した後で、更に可動刃と固定刃とのそれぞれの他の部分を使用して、被切断物の切断を継続できる。このため、可動刃と固定刃との交換を行うために当該切断装置を休止させる頻度を減らし、その稼動し続けられる期間を延長することができる。   Therefore, according to the cutting device according to the present invention, it is not necessary to use other parts of the movable blade and the fixed blade while cutting the workpiece using a part of the movable blade and the fixed blade. After a portion of the fixed blade is worn or missing, the other parts of the movable blade and the fixed blade can be used to continue cutting the workpiece. For this reason, in order to exchange a movable blade and a fixed blade, the frequency which makes the said cutting device rest can be reduced, and the period which can continue operating can be extended.

以下に述べる駆動手段、又は案内手段の他、周知の技術については、それぞれの一般名称を記すものとし図示又は説明は省略する。また、以下に記す駆動手段とは、ピストンロッドを進退させる油圧シリンダ、又はエアシリンダ等のアクチュエータであり、案内手段とは、レールにスライダを滑動自在に係合させて成る滑り対遇を意味する。   In addition to the drive means or guide means described below, for well-known techniques, their general names are described, and illustration or description is omitted. The drive means described below is an actuator such as a hydraulic cylinder or an air cylinder that moves the piston rod back and forth, and the guide means means a slip treatment in which a slider is slidably engaged with a rail. .

図１，２に示すように、切断装置１は、被切断物が通過する開口部２の下縁に固定刃３が設けられたフレーム４と、フレーム４に昇降自在に案内されるスライダ５の下縁に設けられた山形の可動刃６と、被切断物を開口部２の付近で下方に押える押圧駆動手段７と、互いに矢印Ｗで指した幅方向に隔たり開口部２の両側に配置された一対の幅寄せ駆動手段８，９と、後述の切断用駆動手段１０とフィーダ１１とを備える。   As shown in FIGS. 1 and 2, the cutting device 1 includes a frame 4 in which a fixed blade 3 is provided at the lower edge of an opening 2 through which an object to be cut passes, and a slider 5 that is guided by the frame 4 so as to be movable up and down. A chevron-shaped movable blade 6 provided at the lower edge, a pressing drive means 7 for pressing the object to be cut downward in the vicinity of the opening 2, and a widthwise direction pointed to each other by an arrow W, are arranged on both sides of the opening 2. A pair of width-shifting drive means 8 and 9, a cutting drive means 10 and a feeder 11 described later are provided.

フレーム４は、複数の鋼板を一体に溶接して成る門型の構造物であり、その両柱部４１の間に開口部２を形成している。フレーム４の背面側にはフィーダ１１が設置されている。フィーダ１１は、そのフィーディングボックス１２に投入された被切断物を矢印Ｆ方向へ搬送し、この被切断物を開口部２へ送り込むものであれば良い。被切断物とは、例えば解体された自動車の車体、鉄筋等の建築廃材、又はその他の産業廃棄物を集めたものである。固定刃３は、図２，３に示すように、四角形の断面を有し開口部２の幅方向に直線状に延びる長尺な鋼棒体である。この鋼棒体は1本として表しているが、固定刃３が、複数本の鋼棒体を一列に並べたものであっても良い。   The frame 4 is a gate-shaped structure formed by integrally welding a plurality of steel plates, and an opening 2 is formed between both pillar portions 41. A feeder 11 is installed on the back side of the frame 4. The feeder 11 is not limited as long as it feeds the workpiece put in the feeding box 12 in the direction of arrow F and feeds this workpiece into the opening 2. The to-be-cut object is a collection of dismantled automobile bodies, building waste materials such as reinforcing bars, or other industrial waste. As shown in FIGS. 2 and 3, the fixed blade 3 is a long steel rod having a square cross section and extending linearly in the width direction of the opening 2. Although this steel bar is represented as one, the fixed blade 3 may be a plurality of steel bars arranged in a row.

スライダ５は、その両側部を上下方向に案内する一対の案内手段５１を介して、フレーム４の両柱部４１に係合している。スライダ５の上端には、切断用駆動手段１０のピストンロッド１０１が接続されており、切断用駆動手段１０がピストンロッド１０１を上下方向に進退させると、これに従いスライダ５と共に可動刃６が昇降する。固定刃３と可動刃６とは互いに上下方向に対向するが、可動刃６は固定刃３より少し矢印Ｆ方向の前方に位置する。このため、スライダ５が下降すれば、可動刃６は、固定刃３に近接するが突き当ることはなく、固定刃３に滑り接触しながら下降する。   The slider 5 is engaged with both column portions 41 of the frame 4 through a pair of guide means 51 that guides both sides thereof in the vertical direction. The piston rod 101 of the cutting drive means 10 is connected to the upper end of the slider 5, and when the cutting drive means 10 moves the piston rod 101 up and down, the movable blade 6 moves up and down together with the slider 5 accordingly. . The fixed blade 3 and the movable blade 6 oppose each other in the vertical direction, but the movable blade 6 is positioned slightly ahead of the fixed blade 3 in the direction of the arrow F. For this reason, when the slider 5 is lowered, the movable blade 6 comes close to the fixed blade 3 but does not come into contact with it, and descends while slidingly contacting the fixed blade 3.

可動刃６は、図４，５に示すように、四角形の断面を有する長尺な鋼棒体６１を、４個山形に並べて配置し、これら４個の鋼棒体６１を、スライダ５の下縁の段部にホルダ５２で位置決めしボルト５３で固定したものである。可動刃６の両端６２，６３は、互いに幅方向に隔たり、両端６２，６３から幅方向の内方へ向ってエッジ６４，６５がそれぞれ傾斜して延びているので、可動刃６を正面から見ると、一端６２から幅方向の内方へ向って上昇傾斜するエッジ６４と、他端６３から幅方向の内方へ向って上昇傾斜するエッジ６５とが成す形状が山形となる。これらのエッジ６４，６５を説明の便宜により、それぞれ右エッジ６４、及び左エッジ６５と称して以下で区別する。   As shown in FIGS. 4 and 5, the movable blade 6 includes four long steel rods 61 having a square cross section arranged in a mountain shape, and these four steel rods 61 are placed under the slider 5. It is positioned with a holder 52 and fixed with bolts 53 at the edge step. Both ends 62 and 63 of the movable blade 6 are spaced apart from each other in the width direction, and the edges 64 and 65 extend from the both ends 62 and 63 inward in the width direction so that the movable blade 6 is viewed from the front. A shape formed by an edge 64 inclined upward from the one end 62 inward in the width direction and an edge 65 inclined upward from the other end 63 inward in the width direction is a mountain shape. For convenience of explanation, these edges 64 and 65 are referred to as a right edge 64 and a left edge 65, respectively, and are distinguished below.

また、鋼棒体６１は、その表裏に同形状の座刳りがそれぞれ形成されているので、図示の鋼棒体６１をその表裏を反転させた姿勢、又は上下を反転させた姿勢にしても、スライダ５に取付けることができる。これは、鋼棒体６１の四隅が総てエッジ６４，６５と成り得るので、四隅の何れかに磨耗、又は欠損が生じた場合に、その他の隅部を図５に矢印Ｅで指した箇所に位置させるためである。   In addition, since the steel rod body 61 is formed with the same shape of the seating on the front and back, the steel rod body 61 illustrated in FIG. It can be attached to the slider 5. This is because all the four corners of the steel bar 61 can be edges 64 and 65, and when any of the four corners is worn or broken, the other corners are indicated by arrows E in FIG. This is because it is located in the area.

図３に示すように、押圧駆動手段７は、そのピストンロッド７１を上下方向に進退させることができ、ピストンロッド７１の下端に、押圧部材７２が水平姿勢で接合されている。一対の幅寄せ駆動手段８，９は、相対向する方向にそれぞれのピストンロッド８１，９１を進退できる。ピストンロッド８１，９１のそれぞれの先端には作動部１３が接続されている。作動部１３は、その先端付近を図３で板として表しているが、実際には図６（ａ）に示すような幅方向に厚みを有する箱体である。一対の幅寄せ駆動手段８，９がピストンロッド８１，９１を進退させると、これに従い作動部１３が幅方向に進退する。   As shown in FIG. 3, the pressing drive means 7 can move the piston rod 71 in the vertical direction, and the pressing member 72 is joined to the lower end of the piston rod 71 in a horizontal posture. The pair of width-shifting drive means 8 and 9 can advance and retract the piston rods 81 and 91 in opposite directions. The operating portion 13 is connected to the tip of each of the piston rods 81 and 91. The vicinity of the tip of the actuating portion 13 is shown as a plate in FIG. 3, but in practice it is a box having a thickness in the width direction as shown in FIG. When the pair of width-shifting drive means 8 and 9 moves the piston rods 81 and 91 forward and backward, the operating portion 13 advances and retracts in the width direction accordingly.

以上に述べた切断装置１によれば、図６（ａ）に示すように、一の幅寄せ駆動手段８がその作動部１３を後退位置で停止させた状態で、他の幅寄せ駆動手段９がその作動部１３を前進させることにより、被切断物１４を幅方向の一方に寄せることができる。更に、スライダ５が下降する行程で、可動刃６の右エッジ６４と固定刃３との間に、幅方向の一方に寄せられた被切断物１４を挟み、この被切断物１４を切断することができる。   According to the cutting device 1 described above, as shown in FIG. 6A, in the state where one width-shifting drive unit 8 stops its operating portion 13 at the retracted position, the other width-shifting drive unit 9 However, the workpiece 14 can be brought close to one side in the width direction by moving the operating portion 13 forward. Further, in the process of lowering the slider 5, the workpiece 14 brought close to one side in the width direction is sandwiched between the right edge 64 of the movable blade 6 and the fixed blade 3, and the workpiece 14 is cut. Can do.

例えば、被切断物１４を切断する上記の動作が所定の期間繰り返されると、可動刃６の右エッジ６４が徐々に磨耗し又は欠損することがある。また、固定刃３についても、可動刃６に対応する箇所で磨耗又は欠損が生じることがある。このような不具合が起こりそうな時期を見計らって、図６（ｂ）に示すように、他の幅寄せ駆動手段９がその作動部１３を後退位置で停止させた状態で、一の幅寄せ駆動手段８がその作動部１３を前進させることにより、被切断物１４を幅方向の他方に寄せることができる。更に、スライダ５が下降する行程で、可動刃６の左エッジ６５と固定刃３との間に、幅方向の他方に寄せられた被切断物１４を挟み、この被切断物１４を切断することができる。   For example, when the above-described operation for cutting the workpiece 14 is repeated for a predetermined period, the right edge 64 of the movable blade 6 may be gradually worn or missing. In addition, the fixed blade 3 may be worn or chipped at a location corresponding to the movable blade 6. As shown in FIG. 6B, in a state where such a malfunction is likely to occur, another width-shifting drive means 9 stops its operating portion 13 at the retracted position, and one width-shift drive is performed. When the means 8 advances the operating portion 13, the workpiece 14 can be moved toward the other side in the width direction. Further, in the process of lowering the slider 5, the workpiece 14 brought close to the other in the width direction is sandwiched between the left edge 65 of the movable blade 6 and the fixed blade 3, and the workpiece 14 is cut. Can do.

このように、右エッジ６４と左エッジ６５とを適宜に使い分けられるので、可動刃６と固定刃３の一部分を使用して被切断物１４を切断する間、可動刃６と固定刃３の他の部分を使用しなくて済むので、可動刃６と固定刃３の一部分が磨耗し又は欠損した後で、更に可動刃６と固定刃３の他の部分を使用して、被切断物１４の切断を継続できる。従って、可動刃６と固定刃３との交換を行うために切断装置１を休止させる頻度を減らし、その稼動し続けられる期間を延長することができる。   As described above, the right edge 64 and the left edge 65 can be properly used, so that the movable blade 6 and the fixed blade 3 can be used while the movable blade 6 and a part of the fixed blade 3 are used to cut the workpiece 14. Therefore, after a part of the movable blade 6 and the fixed blade 3 is worn out or lost, the other part of the movable blade 6 and the fixed blade 3 is used to further remove the workpiece 14. You can continue cutting. Accordingly, it is possible to reduce the frequency of pausing the cutting device 1 in order to exchange the movable blade 6 and the fixed blade 3, and to extend the period during which the cutting device 1 can continue to operate.

更に、可動刃６は山形であるため、被切断物１４を切断する毎に可動刃６を昇降させる上下方向のストロークＳを比較的短くすることができる。これは、可動刃６の右エッジ６４又は左エッジ６５が、被切断物１４を上下方向に横切るために必要なストロークは、従来例のように幅方向の一端から他端まで直線状にエッジが傾斜した可動刃が、被切断物１４を上下方向に横切る場合よりも短くて済むからである。従って、スライダ５を開口部２の上方へ案内する高さを抑えらるので、切断装置１の全高を抑えることができる。   Furthermore, since the movable blade 6 has a mountain shape, the vertical stroke S for raising and lowering the movable blade 6 every time the workpiece 14 is cut can be made relatively short. This is because the stroke required for the right edge 64 or the left edge 65 of the movable blade 6 to cross the workpiece 14 in the up-down direction is a straight line from one end to the other end in the width direction as in the conventional example. This is because the inclined movable blade can be shorter than the case where the workpiece 14 is traversed in the vertical direction. Therefore, since the height for guiding the slider 5 to the upper side of the opening 2 is suppressed, the overall height of the cutting device 1 can be suppressed.

図７（ａ）に示すように、可動刃６の右エッジ６４よりも左エッジ６５の幅方向の寸法を長くすることにより、右エッジ６４と左エッジ６５とが非対称な山形を成すようにしても良い。この場合、他の幅寄せ駆動手段９がその作動部１３を後退位置で停止させた状態で、一の幅寄せ駆動手段８がその作動部１３を左エッジ６５の下方に達するまで前進させる。これにより、被切断物１４が左エッジ６５の下方に位置決めされる。更に、スライダ５が下降する行程で、可動刃６の左エッジ６５と固定刃３との間で被切断物１４を切断することができる。   As shown in FIG. 7A, the width of the left edge 65 is made longer than the right edge 64 of the movable blade 6 so that the right edge 64 and the left edge 65 form an asymmetric mountain shape. Also good. In this case, with the other width adjusting drive means 9 stopping the operating portion 13 at the retracted position, one width adjusting drive means 8 advances the operating portion 13 until it reaches below the left edge 65. As a result, the workpiece 14 is positioned below the left edge 65. Further, the workpiece 14 can be cut between the left edge 65 of the movable blade 6 and the fixed blade 3 in the process of lowering the slider 5.

或いは、図７（ｂ）に示すように、一の幅寄せ駆動手段８がその作動部１３を後退位置で停止させた状態で、他の幅寄せ駆動手段９がその作動部１３を右エッジ６４の下方に達するまで前進させる。これにより、被切断物１４が右エッジ６４の下方に位置決めされる。更に、スライダ５が下降する行程で、可動刃６の右エッジ６４と固定刃３との間で被切断物１４を切断することができる。   Alternatively, as shown in FIG. 7B, in the state where one width adjusting driving means 8 stops the operating portion 13 at the retracted position, the other width adjusting driving means 9 sets the operating portion 13 to the right edge 64.

このように、幅方向の寸法が異なる右エッジ６４と左エッジ６５とを適宜に使い分けられるので、被切断物１４の量が比較的多いときには、これを可動刃６の左エッジ６５と固定刃３との間で切断し、被切断物１４の量が比較的少ないときには、これを可動刃６の右エッジ６４と固定刃３との間で切断できる。   As described above, the right edge 64 and the left edge 65 having different dimensions in the width direction can be appropriately used. Therefore, when the amount of the workpiece 14 is relatively large, the left edge 65 and the fixed blade 3 of the movable blade 6 are used. When the amount of the workpiece 14 is relatively small, it can be cut between the right edge 64 of the movable blade 6 and the fixed blade 3.

尚、本発明は、その趣旨を逸脱しない範囲で当業者の知識に基づき種々なる改良、修正、又は変形を加えた態様で実施できる。例えば、図８に示すように、可動刃６が、一端６２から幅方向の内方へ向って下降傾斜するエッジ６６と、他端６３から幅方向の内方へ向って下降傾斜するエッジ６７とを有すものであっても良い。この場合も本発明の効果を達成することができる。   It should be noted that the present invention can be implemented in variously modified, modified, or modified forms based on the knowledge of those skilled in the art without departing from the spirit of the present invention. For example, as shown in FIG. 8, the movable blade 6 has an edge 66 inclined downward from one end 62 in the width direction, and an edge 67 inclined downward from the other end 63 in the width direction. It may be a thing having. Also in this case, the effect of the present invention can be achieved.
