Description

この発明は、塗装時などに用いられるマスキングシートをカットするマスキングシートカッターに関する。   The present invention relates to a masking sheet cutter for cutting a masking sheet used at the time of painting.

従来から、塗装対象以外の部分が塗料で汚れないように覆うための塗装用のマスキングシートのロールがあった。このマスキングシートのロールは、樹脂製のシート部材の一端側に粘着テープを取り付けるとともに、シートを一定の幅に折りたたんで帯状にしたものをロール状に巻いたものである。
また、このようなマスキングシートは、引き出しながら粘着テープを利用して目的の個所に固定することができる。このようなロールを保持し、引き出されたマスキングシートを切断することができるマスキングシートカッターとして、特許文献1に示すものが知られていた。
2. Description of the Related Art Conventionally, there has been a masking sheet roll for coating to cover portions other than the object to be painted so as not to get dirty with paint. The masking sheet roll is obtained by attaching an adhesive tape to one end of a resin sheet member, and folding a sheet into a belt shape and winding it into a roll.
Moreover, such a masking sheet can be fixed to a target location using an adhesive tape while being pulled out. As a masking sheet cutter capable of holding such a roll and cutting the drawn masking sheet, the one shown in Patent Document 1 has been known.

図8は、この従来のマスキングシートカッターを、ロールの軸線に直交する面で切った断面図である。
このマスキングシートカッターは、ロール1を保持する一対の挟持片2を備えた本体3内に、刃4を一体的に保持した保持体5を組み込んでいる。そして、本体3の側面に突出した図示していない押し部を押すと、保持体5が移動して刃4を本体から露出させるようにしている。
FIG. 8 is a cross-sectional view of this conventional masking sheet cutter cut along a plane perpendicular to the axis of the roll.
This masking sheet cutter incorporates a holding body 5 that integrally holds a blade 4 in a main body 3 having a pair of clamping pieces 2 that hold a roll 1. And if the push part which is not shown in figure which protruded on the side surface of the main body 3 is pushed, the holding body 5 will move and the blade 4 will be exposed from a main body.

通常は、刃4が本体3内に収容されるように保持体5に、ばね部材6の弾性力を作用させていて、上記弾性力に抗して押し部を押したときにのみ、ロール幅に対応させた刃4が露出するようにしている。
そして、上記ばね部材6は、その一端を保持体5のばね受け部5aに接触させるとともに、他端をばね受け部材7のばね受け部7aに接触させ、このばね受け部7aと保持体5のばね受け部5aとの間で弾性力を発揮させている。また、ばね受け部材7は、本体3に止めねじ8で固定されている。
Usually, only when the elastic force of the spring member 6 is applied to the holding body 5 so that the blade 4 is accommodated in the main body 3 and the pressing portion is pressed against the elastic force, the roll width is increased. The blade 4 corresponding to is exposed.
The spring member 6 has one end in contact with the spring receiving portion 5a of the holding body 5 and the other end in contact with the spring receiving portion 7a of the spring receiving member 7, and the spring receiving portion 7a and the holding body 5 An elastic force is exerted between the spring receiving portion 5a. The spring receiving member 7 is fixed to the main body 3 with a set screw 8.

特開2005−288652号公報JP-A-2005-288552

上記のようなマスキングシートカッターは、本体3から押し出された刃4をシートに押し付けることによってカットするものであるが、樹脂製のシートは腰が弱いうえ何層にも折りたたまれているので、単に刃4を押し付けただけでは切断しにくい。特に、折り重なったシートの層がずれてしまうと、押し付けただけでは切断できないため、刃4をずらしながら切断する必要がある。このように、シート上で刃4をずらして切断することを繰り返すと、短期間で刃4の切れ味が悪くなってしまう。そのため、刃4を頻繁に交換しなければない。   The masking sheet cutter as described above is cut by pressing the blade 4 pushed out from the main body 3 against the sheet, but the resin sheet is weak and is folded in several layers. It is difficult to cut by simply pressing the blade 4. In particular, if the folded layers of sheets are displaced, they cannot be cut simply by being pressed, so it is necessary to cut the blade 4 while shifting it. As described above, when the blade 4 is repeatedly shifted and cut on the sheet, the sharpness of the blade 4 is deteriorated in a short period of time. Therefore, the blade 4 must be replaced frequently.

しかし、上記従来のマスキングシートカッターでは、刃4と一体的になった保持体5が、ばね部材6で本体3に押し付けられている。そして、ばね部材6は、その一端をばね受け部材7で支持されているため、保持体5を取り外すためには、止めねじ8を外して、ばね受け部材7とばね部材6とを本体3から取り外す必要があった。
つまり、刃4を交換するためには、止めねじ8を外し、ばね受け部材7及びばね部材6を外してから、保持体5を取り出さなければならない。そして、上記取り外した保持体5を新たな保持体5に替え、この保持体5を、ばね部材6とばね受け部材7とともに本体3内に組み込み、止めねじ8によってばね受け部材7を本体3に固定しなければならない。
However, in the conventional masking sheet cutter, the holding body 5 integrated with the blade 4 is pressed against the main body 3 by the spring member 6. Since one end of the spring member 6 is supported by the spring receiving member 7, in order to remove the holding body 5, the set screw 8 is removed, and the spring receiving member 7 and the spring member 6 are removed from the main body 3. I had to remove it.
That is, in order to replace the blade 4, the holding screw 5 must be taken out after removing the set screw 8 and the spring receiving member 7 and the spring member 6. Then, the removed holding body 5 is replaced with a new holding body 5, and this holding body 5 is incorporated in the main body 3 together with the spring member 6 and the spring receiving member 7, and the spring receiving member 7 is attached to the main body 3 by the set screw 8. Must be fixed.

このように、上記した従来のマスキングシートカッターは、刃を交換する際には、本体の分解・組み立てなどが必要で、手間がかかるという問題があった。
この発明の目的は、本体の分解や組み立てが必要なく、簡単に刃を交換できるマスキングシートカッターを提供することである。
As described above, the conventional masking sheet cutter described above has a problem that it takes time and effort to disassemble and assemble the main body when replacing the blade.
An object of the present invention is to provide a masking sheet cutter in which a blade can be easily replaced without requiring disassembly or assembly of a main body.

この発明は、折りたたんで帯状にして巻かれたマスキングシートのロールを回転自在に保持する本体と、この本体から出入自在にした替刃部材とを備え、
上記替刃部材を上記ロールから引き出されたマスキングシートの方向に突出させて先端の刃部で上記折りたたまれたマスキングシートを切断するマスキングシートカッターを前提とする。
上記発明を前提とし、第1の発明は、上記本体には、作業者の操作力を作用させたとき上記替刃部材と一体となって上記本体内で移動する移動部材を設け、上記替刃部材は、弾性力によって上記移動部材の連結部を挟持するための一対の連結片を備え、上記連結片と上記連結部とを上記替刃部材の突出方向の力で分離可能にするとともに、上記移動部材に対して、上記替刃部材の幅方向の移動を規制する第1のストッパ機構及び上記替刃部材の厚み方向の移動を規制する第2のストッパ機構を備えたことを特徴とする。
This invention comprises a main body rotatably holding the masking sheet roll wound with a strip folded, and a blade member that is freely and out from the body,
It is premised on a masking sheet cutter that projects the replaceable blade member in the direction of the masking sheet drawn out from the roll and cuts the folded masking sheet with the blade portion at the tip.
Based on the above invention, the first invention is provided with a moving member that moves integrally with the replaceable blade member when the operator's operating force is applied to the main body, The member includes a pair of connecting pieces for holding the connecting portion of the moving member by elastic force, and the connecting piece and the connecting portion can be separated by the force in the protruding direction of the replaceable blade member. A first stopper mechanism that restricts movement of the replaceable blade member in the width direction relative to the moving member, and a second stopper mechanism that restricts movement of the replaceable blade member in the thickness direction are provided . .

の発明は、上記連結片に対向する上記連結部における2側面のそれぞれに係止突起が設けられるとともに上記替刃部材の一対の連結片のそれぞれに上記連結部の係止突起に対応する係止突起が設けられ、上記一対の連結片間に上記連結部を挿入する過程において上記連結片の弾性変形によって上記連結片の係止突起が上記移動部材の連結部の係止突起を乗り越え、その状態で上記連結片が上記連結部を挟持し、上記移動部材からの上記替刃部材の脱落を防止することを特徴とする。 The second invention is to provide a locking projection is provided on each of two sides of the connecting portion opposite to the connecting piece, corresponding to the locking projection of the connecting portions to the respective pair of connecting pieces of said blade member In the process of inserting the connecting portion between the pair of connecting pieces, the engaging protrusion of the connecting piece gets over the engaging protrusion of the connecting portion of the moving member by the elastic deformation of the connecting piece. In this state, the connecting piece sandwiches the connecting portion to prevent the replacement blade member from falling off the moving member .

第1の発明は、本体内で移動する移動部材に対して、替刃部材を着脱可能に設けたので、本体を分解したり組み立てたりすることなく、簡単に替刃部材を交換することができる。そのため、いつでも切れ味の良い状態でマスキングシートカッターを使用できる。
また、替刃部材を着脱するための力の方向が移動部材の出入方向、すなわち替刃部材の刃を露出させる方向に沿っているので、露出した刃をシートに押し付ける際に作用する力が、替刃部材を引き抜く方向と逆方向の力になる。したがって、カット作業中に替刃部材が移動部材から外れることがない。
つまり、替刃部材の交換を容易にしながら、シートをカットする際に替刃部材が外れてしまうようなことがない。
In the first invention, since the replaceable blade member is detachably provided with respect to the moving member that moves in the main body, the replaceable blade member can be easily replaced without disassembling or assembling the main body. . Therefore, the masking sheet cutter can be used at any time with a good sharpness.
In addition, since the direction of the force for attaching and detaching the replaceable blade member is along the direction of moving in and out of the moving member, that is, the direction in which the blade of the replaceable blade member is exposed, the force acting when pressing the exposed blade against the sheet is The force is in the direction opposite to the direction in which the replaceable blade member is pulled out. Therefore, the replaceable blade member does not come off the moving member during the cutting operation.
That is, the replacement blade member does not come off when cutting the sheet while facilitating replacement of the replacement blade member.

しかも、上記連結部には、上記替刃部材の幅方向の移動を規制する第1のストッパ機構と、上記替刃部材の厚み方向の移動を規制する第2のストッパ機構とを備えているので、移動部材に対して替刃部材が幅方向及び厚み方向にもずれにくくなる。したがって、シートをカットする際に、替刃部材ががたついたりしないで、折りたたんだシートもカットしやすくなる。
の発明によれば、替刃部材が移動部材から容易に外れることがない
In addition, the connecting portion includes a first stopper mechanism that restricts movement of the replaceable blade member in the width direction and a second stopper mechanism that restricts movement of the replaceable blade member in the thickness direction. The replaceable blade member is less likely to shift in the width direction and the thickness direction with respect to the moving member . Therefore, when you cut the sheet, do not or rattling the blade member, the seat is also easy to cut folded Kunar.
According to the second invention, the replaceable blade member is not easily detached from the moving member .

When the blade 25 is sandwiched between the sandwiching portion 23a of the main body member 23 and the sandwiching portion 24a of the pressing member 24 and the hook portion 23d is fitted into the hooking hole 24b, these members are integrated to form the replaceable blade member 21. Complete.
In such a replaceable blade member 21, the pair of trapezoidal connection pieces 23 e and 24 c described above are provided on the base end side of the blade 25 with a predetermined facing interval. These connecting pieces 23e, between 24c, in the course of inserting the connecting portion 20c of the moving member 20, as shown in FIG. 7, the locking projections 23 f and 24d of the blade member 21 side locking of the moving member 20 If the positional relationship over the projection 20f is reached, the replaceable blade member 21 functions as the third stopper mechanism of the present invention, and the replaceable blade member 21 is connected without dropping from the moving member 20. Incidentally, the locking projection 23 f and 24d of the blade member 21 is at to overcome the locking protrusion 20f of the movable member 20, the connecting piece 23e and 24c are elastically deformed.

図7に示すように移動部材20に替刃部材21が連結されると、替刃部材21側の連結片23e,24cは、移動部材20側の台形凹部20dに一致した状態で、連結部20cを挟持することになる。
また、上記連結片23e,24c間では、上記ストッパ突部23g及び24eが一体となって移動部材20の切欠き部20eにはまって、替刃部材21の幅方向の移動を規制する。
As shown in FIG. 7, when the replaceable blade member 21 is connected to the moving member 20, the connecting pieces 23 e and 24 c on the replaceable blade member 21 side are aligned with the trapezoidal recess 20 d on the moveable member 20 side. Will be pinched.
Further, between the connecting pieces 23e and 24c, the stopper protrusions 23g and 24e are integrated into the notch portion 20e of the moving member 20 to restrict the movement of the replaceable blade member 21 in the width direction.

したがって、上記台形凹部20dと連結片23e,24c、ストッパ突部23g及び24eと切欠き部20eが、それぞれ、この発明の第1ストッパ機構を構成し、替刃部材21は、幅方向の移動を規制している。
また、上記連結部20cを一対の挟持片23e,24cで挟持する構成が、替刃部材21の厚み方向の移動を規制する第2ストッパ機構を構成する
Therefore, the trapezoidal recess 20d, the connecting pieces 23e and 24c, the stopper protrusions 23g and 24e, and the notch 20e constitute the first stopper mechanism of the present invention, and the replaceable blade member 21 moves in the width direction. It is regulated.
Moreover, the structure which clamps the said connection part 20c with a pair of clamping pieces 23e and 24c comprises the 2nd stopper mechanism which regulates the movement of the replaceable blade member 21 in the thickness direction .

Is rotated, the inclined surface 16c at the tip of the rotated operation member 16 is pressed while sliding on the plate-like portion 20b serving as the pressing surface of the present invention, and the moving member 20 is moved. When the moving member 20 moves, the replaceable blade member 21 connected to the moving member 20 moves integrally, and the blade 25 is protruded from the main body 10 to cut the masking sheet drawn from the roll.

また、上記移動部材20は、上記正面板11と、区画壁17及びガイド突部17aとに挟まれているので、これら上記正面板11、区画壁17及びガイド突部17aが、ガイド部となって、移動部材20の移動方向を直線方向にガイドする。したがって、操作部材16が回動しても、移動部材20は直線方向に移動し、替刃部材21を一定の方向に突出させることができる。
そして、本体10の収容部19から先端側を突出させた替刃部材21は、上記したように、移動部材20に対して幅方向及び厚み方向の移動が規制されているため、ロールから引き出されたマスキングシートに押し当てて、幅方向や厚み方向にずらしたとしても、移動部材20に対してがたついたり、外れたりしてしまうことがなく、安定してマスキングシートをカットすることができる。
Further, since the moving member 20 is sandwiched between the front plate 11, the partition wall 17 and the guide projection 17a, the front plate 11, the partition wall 17 and the guide projection 17a serve as a guide portion. Thus, the moving direction of the moving member 20 is guided in the linear direction. Therefore, even if the operation member 16 rotates, the moving member 20 moves in the linear direction, and the replaceable blade member 21 can protrude in a certain direction.
And since the replacement blade member 21 which protruded the front end side from the accommodating part 19 of the main body 10 is controlled to move in the width direction and the thickness direction with respect to the moving member 20 as described above, it is pulled out from the roll. Even if it is pressed against the masking sheet and shifted in the width direction or thickness direction, the masking sheet can be stably cut without rattling or detachment from the moving member 20. .

また、上記のような替刃部材21を交換する際には、本体10の収容部19の下端開口から、替刃部材21を突出させ、本体部材3の一対の支持部23bを挟みもって引っ張るだけで足りる。替刃部材21をその突出方向に沿って引っ張れば、上記連結片23e,24cが弾性変形して、これら連結片23e,24cに形成された係止突起23f,24dが移動部材20の係止突起20fを乗り越えて移動部材20から替刃部材21を外すことができる。
Further, when replacing the blade member 21 as described above, from the lower end opening of the accommodating portion 19 of the body 10, to protrude the blade member 21, pulls with sandwiching the pair of support portions 23b of the body member 2 3 Just enough. When the replaceable blade member 21 is pulled along the protruding direction, the connecting pieces 23e and 24c are elastically deformed, and the locking protrusions 23f and 24d formed on the connecting pieces 23e and 24c are the locking protrusions of the moving member 20. The replaceable blade member 21 can be removed from the moving member 20 over 20f.

また、新たな替刃部材21を取り付ける際には、上記操作部材16によって移動部材を押し下げた状態で、替刃部材21を、取り外したときと反対に、収容部19に押し込んで、上記一対の連結片23e,24dを移動部材20の連結部20cにはめ合わせるようにすればよい。替刃部材21を押し込むと、連結片23e,24dが弾性変形し、これら連結片23e,24dに形成された係止突起23f,24dが移動部材20の係止突起20fを乗り越えて両部材の連結が完了する。
このように、この実施形態では、替刃部材21の着脱時に、本体10の分解や組み立てが必要ないので、替刃部材21の交換作業が簡単にできる。そのため、いつでも刃25の切れ味の良い状態を保つことができる。
In addition, when attaching a new replaceable blade member 21, the replaceable blade member 21 is pushed into the accommodating portion 19 in the state where the moving member is pushed down by the operation member 16. The connecting pieces 23e and 24d may be fitted to the connecting portion 20c of the moving member 20. When the replaceable blade member 21 is pushed in, the connecting pieces 23e and 24d are elastically deformed, and the locking projections 23f and 24d formed on the connecting pieces 23e and 24d get over the locking projection 20f of the moving member 20 to connect the two members. Is completed.
Thus, in this embodiment, since the disassembly and assembly of the main body 10 are not required when the replaceable blade member 21 is attached or detached, the replacement work of the replaceable blade member 21 can be easily performed. Therefore, the sharp state of the blade 25 can be maintained at any time.

なお、本体10における一方の挟持片12に形成したストッパ孔12bには、スライド可能なストッパ部材26を組み込んでいる。このストッパ部材26は、図1に示すように、正面板11側に位置しているときには、回動する操作部材16に当接してその回動を規制し、正面板11と反対側端部に移動させたときには、操作部材16の回動を邪魔しないようにしている。したがって、上記ストッパ部材26を図1の位置に保っておけば、替刃部材21が不用意に突出して、露出した刃25でけがをするようなことも防止できる。
この実施形態のマスキングシートカッターは、一端側に粘着テープを設けたマスキングシートをロールから引き出して、貼りながらカットすることができるが、粘着テープを備えていないマスキングシートのロールにも用いることができる。
A slidable stopper member 26 is incorporated in the stopper hole 12b formed in one clamping piece 12 in the main body 10. As shown in FIG. 1, when the stopper member 26 is located on the front plate 11 side, the stopper member 26 abuts on the rotating operation member 16 to restrict the rotation, and is arranged at the end opposite to the front plate 11. When moved, the rotation of the operation member 16 is not disturbed. Therefore, if the stopper member 26 is kept at the position shown in FIG. 1, it is possible to prevent the replaceable blade member 21 from inadvertently protruding and being injured by the exposed blade 25.
The masking sheet cutter of this embodiment can be cut while sticking out a masking sheet provided with an adhesive tape on one end side, and can also be used for a masking sheet roll not provided with an adhesive tape. .
