Can not. Therefore, the cutter holder must be removed from the cutter lifting / lowering member, and the adjustment of the entrance / exit of the tip of the variable positioning member must be adjusted using a dedicated jig, and there is a problem that it takes time to correct the inclination of the cutting edge of the cutter blade edge. It was.
Therefore, an object of the present invention is to solve the above-mentioned problems, and to provide a sheet cutting machine that can quickly correct the inclination of the cutter blade edge in the crossover direction without employing a large-scale mechanism like the prior art. Objective.

本発明のシート切断機は、カッタを備えたカッタホルダをカッタ昇降部材の左右に夫々設けた位置決め部材に当接させ、その状態でカッタホルダをカッタ昇降部材に装着して成るシート切断機において、カッタ昇降部材の上下位置決め部材に少なくとも一方の位置決め部材の上下位置を他方の位置決め部材の上下位置に対して調整する位置調整具を設け、その位置調整具により一方の位置決め部材を他方の位置決め部材に対して上下移動させ、各位置決め部材に当接させるカッタホルダに備えたカッタ刃先の刃渡り方向の傾きを補正するようにしたことを特徴とする。具体的には、前記位置調整具はマイクロメータヘッドであり、マイクロメータヘッドの先端にカッタホルダを当接させるようにしたことを特徴とする。   The sheet cutting machine according to the present invention is a sheet cutting machine in which a cutter holder provided with a cutter is brought into contact with positioning members provided on the left and right sides of the cutter lifting member, and the cutter holder is mounted on the cutter lifting member in this state. A position adjustment tool for adjusting the vertical position of at least one positioning member with respect to the vertical position of the other positioning member is provided on the vertical positioning member of the member, and the positioning member is used to move one positioning member to the other positioning member. It is characterized in that the inclination in the blade crossing direction of the cutter blade edge provided in the cutter holder that is moved up and down and brought into contact with each positioning member is corrected. Specifically, the position adjusting tool is a micrometer head, and a cutter holder is brought into contact with the tip of the micrometer head.

本発明では、カッタ昇降部材の位置決めレールの左右に設けた位置決め部材の一方をマイクロメータヘッドの先端とし、他方の位置決め部材の上下位置に対してマイクロメータヘッドの先端の上下位置を調整することにより、カッタホルダをカッタ昇降部材に取り付けた状態でカッタ刃先の刃渡り方向の傾きを速やかに補正することが可能となる。また、位置決めレールにマイクロメータヘッドを取り付けた簡単な構成であるので、既存のシート切断機に採用した場合でもそのシート切断機が大型化となることはない。   In the present invention, one of the positioning members provided on the left and right of the positioning rail of the cutter lifting member is used as the tip of the micrometer head, and the vertical position of the tip of the micrometer head is adjusted with respect to the vertical position of the other positioning member. In addition, it is possible to quickly correct the inclination of the cutting edge of the cutter blade edge with the cutter holder attached to the cutter lifting member. In addition, since the micrometer head is attached to the positioning rail, the sheet cutting machine does not become large even when it is adopted in an existing sheet cutting machine.

図1は、カッタホルダ1をシート切断機Mのカッタ昇降部材25に装着した正面図である。カッタホルダ1は、本体2と、カッタ押え部材3と、本体2の長手両側に設けられる一対の掛止部材4とを備えている。横長で下端を刃先5aとしたカッタ5は、本体2とカッタ押え部材3との間に挟み込まれ、複数の締め付けボルト6により挟持固定される。前記一対の掛止部材4は、夫々本体2の前面の両側にボルト7で固着され、本体2上端から上方に伸びて上端が本体2側に向けて張り出す張り出し部8に形成され、張り出し部8と本体2の上面との間に嵌合部9が形成されている。張り出し部8には、上下方向に固定ねじ10が螺合されている。本体2には、カッタ昇降部材25に取り付けるときに、カッタ昇降部材25側に螺合された取り付けボルト32の頭部32aが通過可能な左右一対の取付孔11が形成され、また、カッタホルダ1の扱いを容易にするための把手12が固着してある。   FIG. 1 is a front view in which the cutter holder 1 is mounted on the cutter lifting member 25 of the sheet cutting machine M. FIG. The cutter holder 1 includes a main body 2, a cutter pressing member 3, and a pair of latching members 4 provided on both longitudinal sides of the main body 2. The cutter 5 which is horizontally long and has a blade edge 5a at the lower end is sandwiched between the main body 2 and the cutter pressing member 3, and is clamped and fixed by a plurality of fastening bolts 6. The pair of hooking members 4 are respectively fixed to both sides of the front surface of the main body 2 with bolts 7, formed on the overhanging portion 8 that extends upward from the upper end of the main body 2 and overhangs the upper end toward the main body 2 side. A fitting portion 9 is formed between 8 and the upper surface of the main body 2. A fixing screw 10 is screwed onto the overhanging portion 8 in the vertical direction. The body 2 is formed with a pair of left and right mounting holes 11 through which a head 32 a of a mounting bolt 32 screwed to the cutter lifting member 25 side can be passed when attached to the cutter lifting member 25. A handle 12 for easy handling is fixed.

カッタ昇降部材25の前面25aには、カッタホルダ1の上下位置を定める上下位置決め部材として、左右に伸びる位置決めレール26が複数のボルト13により固着されている。位置決めレール26には先端が左右下側に突出するように位置決め部材27,28が設けられている。位置決めレール26に設けた位置調整具29により、少なくとも一方の位置決め部材27の上下位置を他方の位置決め部材28の上下位置に対して調整するようになっている。本実施形態では、前記位置調整具はマイクロメータヘッド29であって、マイクロメータヘッド29の先端を一方の位置決め部材27として位置決めレール26の下側に突出させてある。他方の位置決め部材は位置決めレール26に螺合固定された位置決めボルト28である。マイクロメータヘッド29の先端27と位置決めボルト28は、カッタ昇降部材25の幅方向中心線CLを挟んで左右対称な位置に設置されている。位置決めレール26の前面には先端をフック部30とした係止レバー31の基端部が枢着されている。フック部30はカッタ昇降部材25に正面側から螺合されている左右一対の取り付けボルト32の頭部32aとカッタホルダ1の本体2前面との間に入り込んで夫々取り付けボルト32に係脱可能に係止される。   A positioning rail 26 extending to the left and right is fixed to the front surface 25 a of the cutter lifting member 25 by a plurality of bolts 13 as a vertical positioning member that determines the vertical position of the cutter holder 1. Positioning members 27 and 28 are provided on the positioning rail 26 so that the tip protrudes to the lower left and right. A position adjustment tool 29 provided on the positioning rail 26 adjusts the vertical position of at least one positioning member 27 with respect to the vertical position of the other positioning member 28. In the present embodiment, the position adjusting tool is a micrometer head 29, and the tip of the micrometer head 29 is protruded below the positioning rail 26 as one positioning member 27. The other positioning member is a positioning bolt 28 screwed and fixed to the positioning rail 26. The tip 27 of the micrometer head 29 and the positioning bolt 28 are installed at symmetrical positions with respect to the center line CL in the width direction of the cutter lifting member 25. A base end portion of a locking lever 31 whose tip is a hook portion 30 is pivotally attached to the front surface of the positioning rail 26. The hook portion 30 enters between the head portion 32a of the pair of left and right mounting bolts 32 screwed into the cutter lifting member 25 from the front side and the front surface of the main body 2 of the cutter holder 1 so as to be detachable from the mounting bolt 32. Stopped.

前記カッタホルダ1は、係止レバー31を上方に旋回した位置(図1の二点鎖線位置)とし、作業者が把手12を握って機台Mの前方から、本体2の取付孔11を取り付けボルト32に挿通してホルダ1背面をカッタ昇降部材25の前面25aに押し当て、同時に嵌合部9に位置決めレール26を位置させ、その状態で係止レバー31を下方に旋回してフック部30をボルト頭部32aとカッタホルダ1との間で取り付けボルト32に引っ掛けて仮保持する。その状態で、固定ねじ10を捩じ込んでねじ10先端を位置決めレール26の上面に押し当ててカッタホルダ1全体を上方に引き上げ、カッタホルダ1を位置決めレール26の左右下側に突出したマイクロメータヘッド29の先端27と位置決めボルト28の先端に当接させてカッタホルダ1の上下位置を定める。この状態で、取り付けボルト32が締め付けられ、カッタホルダ1がカッタ昇降部材25に装着、固定される。尚、本実施形態では、固定ねじ10によりカッタホルダ1全体を上方に引き上げ、カッタホルダ1を各位置決め部材27,28に当接させるようにしたが、図6(a)のように、ボールプランジャ50を用いてカッタホルダ1全体を上方に引き上げ、カッタホルダ1を各位置決め部材27,28に当接させるようにしてもよい。
図2に示すように、カッタ昇降部材25は板状部材であり、その背面左右に上下方向に案内子36が取り付けられ、それらの案内子36は、ワークテーブルTの上方でワークテーブルTに対して垂直な機台フレーム37の前面左右に固着した上下に長い案内レール38に上下方向に移動するように案内され、図示しないサーボモータと送りねじ機構を介してカッタ昇降部材25が昇降するように構成され、こうしてワークテーブルT上に載置されたシート状ワークWに対して、カッタ5が上下してワークWを切断するようにしてある。
The cutter holder 1 has the locking lever 31 pivoted upward (the two-dot chain line position in FIG. 1), and the operator grasps the handle 12 and attaches the mounting hole 11 of the main body 2 from the front of the machine base M to the mounting bolt. 32, the holder 1 is pressed against the front surface 25a of the cutter lifting / lowering member 25, and the positioning rail 26 is simultaneously positioned on the fitting portion 9. In this state, the locking lever 31 is pivoted downward to bring the hook portion 30 into place. The bolt 32 is hooked on the mounting bolt 32 between the head 32a and the cutter holder 1 and temporarily held. In this state, the fixing screw 10 is screwed in and the tip of the screw 10 is pressed against the upper surface of the positioning rail 26 to pull up the cutter holder 1 as a whole. The upper and lower positions of the cutter holder 1 are determined by abutting against the tip 27 of the cutter and the tip of the positioning bolt 28. In this state, the mounting bolt 32 is tightened, and the cutter holder 1 is attached and fixed to the cutter lifting member 25. In the present embodiment, the entire cutter holder 1 is lifted upward by the fixing screw 10 and the cutter holder 1 is brought into contact with the positioning members 27 and 28. However, as shown in FIG. Alternatively, the cutter holder 1 may be lifted upward so that the cutter holder 1 is brought into contact with the positioning members 27 and 28.
As shown in FIG. 2, the cutter elevating member 25 is a plate-like member, and guides 36 are attached to the back and left and right of the cutter in the vertical direction. These guides 36 are above the work table T with respect to the work table T. The upper and lower guide rails 38 fixed to the front left and right sides of the vertical machine frame 37 are guided so as to move up and down, and the cutter elevating member 25 is moved up and down via a servo motor and a feed screw mechanism (not shown). Thus, the cutter 5 moves up and down with respect to the sheet-like workpiece W placed on the workpiece table T in this way, and cuts the workpiece W.

上記構成のシート切断機Mにおいて、図5(a)のように、カッタ刃先5aの刃渡り方向の傾きの補正が必要な場合には、カッタホルダ1をカッタ昇降部材25に装着、固定している取り付けボルト32を緩め、そして、固定ねじ10を緩めてカッタホルダ1と各位置決め部材(マイクロメータヘッド29の先端27、位置決めボルト28)との当接状態を解除する。その後、マイクロメータヘッド29の先端27の上下位置を位置決めボルト28の上下位置に対して調整する。先端27の上下位置の調整量は、図5(a)の時にワークテーブルTのテーブル上面Taからカッタ刃先5aの刃渡り方向の二箇所を測定して算出されたものである。その後、固定ねじ10を再び捩じ込んでカッタホルダ1を各位置決め部材27,28に当接させると、図5(b)のように、カッタホルダ1に備えたカッタ刃先5aとワークテーブルTのテーブル上面Taとが平行となる。そして、取り付けボルト32が締め付けられ、カッタホルダ1が再びカッタ昇降部材25に装着、固定される。   In the sheet cutting machine M configured as described above, as shown in FIG. 5A, when the correction of the inclination of the cutter blade edge 5a in the blade crossing direction is necessary, the cutter holder 1 is attached to the cutter lifting member 25 and fixed. The bolt 32 is loosened, and the fixing screw 10 is loosened to release the contact state between the cutter holder 1 and each positioning member (the tip 27 of the micrometer head 29, the positioning bolt 28). Thereafter, the vertical position of the tip 27 of the micrometer head 29 is adjusted with respect to the vertical position of the positioning bolt 28. The adjustment amount of the vertical position of the tip 27 is calculated by measuring two points in the blade crossing direction of the cutter blade edge 5a from the table upper surface Ta of the work table T in the case of FIG. After that, when the fixing screw 10 is screwed again to bring the cutter holder 1 into contact with the positioning members 27 and 28, the cutter blade edge 5a provided in the cutter holder 1 and the table upper surface of the work table T as shown in FIG. Ta becomes parallel. Then, the mounting bolt 32 is tightened, and the cutter holder 1 is mounted and fixed to the cutter lifting member 25 again.

従って、一方の位置決め部材(マイクロメータヘッド29の先端27)の上下位置を他方の位置決め部材(位置決めボルト28)の上下位置に対して調整することで、位置決め部材27,28に当接させるカッタホルダ1に備えたカッタ刃先5aの刃渡り方向の補正をカッタ昇降部材25に取り付けた状態(仮保持状態)で行なえると共に、従来のように、カッタホルダ1をカッタ昇降部材25から取り外した後、専用の治具にて可変位置決め部材の微調整を行なうことに比べて、カッタ刃先5aの刃渡り方向の補正を速やかに行うことができる。更に、位置決めレール26にマイクロメータヘッド29を取り付けた簡単な構成であるので、既存のシート切断機Mに採用したとしてもそのシート切断機Mが大型化となることはない。また、一方の位置決め部材27にカッタホルダ1を当接させる他の実施形態として、図6(b)のような位置決め部材27Aを位置調整具29に取り付け、その位置決め部材27Aの先端をカッタホルダ1の本体2に形成した位置決め孔2Aに挿入し、上下位置を調整した位置決め部材27Aに前記位置決め孔2Aの下面を当接させるようにしてあってもよい。   Therefore, the cutter holder 1 to be brought into contact with the positioning members 27 and 28 by adjusting the vertical position of one positioning member (tip 27 of the micrometer head 29) with respect to the vertical position of the other positioning member (positioning bolt 28). The cutting edge direction of the cutter blade edge 5a provided for the cutter can be corrected while attached to the cutter lifting member 25 (temporary holding state), and after the cutter holder 1 is removed from the cutter lifting member 25 as in the prior art, a dedicated jig is used. Compared with the fine adjustment of the variable positioning member with the tool, the cutting edge direction of the cutter blade edge 5a can be corrected quickly. Furthermore, since the micrometer head 29 is simply attached to the positioning rail 26, even if it is adopted in the existing sheet cutting machine M, the sheet cutting machine M will not be enlarged. As another embodiment in which the cutter holder 1 is brought into contact with one positioning member 27, a positioning member 27A as shown in FIG. 6B is attached to the position adjusting tool 29, and the tip of the positioning member 27A is attached to the main body of the cutter holder 1. 2 may be inserted into the positioning hole 2A formed in 2 and the lower surface of the positioning hole 2A may be brought into contact with the positioning member 27A whose vertical position is adjusted.
