被切断部材の切断幅を自由に変更することができる刃物ホルダーユニット２を有するスリッタ装置１は、比較的厚みの薄いリング状の第１丸刃（以下、丸刃と記載）３が装着されているホルダー４と、丸刃３をホルダー４とで同心円状に挟んで複数の保持ボルト７でホルダー４に保持する円筒状の押え蓋５とで構成された刃物ホルダーユニット２が複数備えられている第１回転軸１０と、剛性を有する第２丸刃（以下、下丸刃と記載）２１が丸刃３と対向して装着されている第２回転軸２０と、が平行に設けられて組立てられている。また、丸刃３の刃先側面と下丸刃２１の刃先側面とは、例えば比較的厚い被切断部材の場合は所定のスキマを保つように調整され、比較的薄い被切断部材の場合は所定の接触圧力を保つように調整されている。そして第１回転軸１０と第２回転軸２０との間に送られた帯状の被切断部材を長さ方向に沿って複数の狭幅帯体に切断するものである。 A slitter device 1 having a blade holder unit 2 that can freely change the cutting width of a member to be cut is provided with a ring-shaped first round blade (hereinafter referred to as a round blade) 3 having a relatively thin thickness. A plurality of blade holder units 2 each having a holder 4 and a cylindrical presser lid 5 which are held by the holder 4 with a plurality of holding bolts 7 with the circular blade 3 concentrically sandwiched between the holder 4 and the holder 4 are provided. A first rotary shaft 10 and a second rotary shaft 20 on which a rigid second round blade (hereinafter referred to as a lower round blade) 21 is mounted facing the round blade 3 are provided in parallel and assembled. It has been. Further, the edge side surface of the round blade 3 and the edge side surface of the lower round blade 21 are adjusted to maintain a predetermined clearance in the case of a relatively thick member to be cut, for example, and predetermined in the case of a relatively thin member to be cut. It is adjusted to maintain the contact pressure. The strip-shaped member to be cut sent between the first rotary shaft 10 and the second rotary shaft 20 is cut into a plurality of narrow strips along the length direction.
ところで、以上のようなスリッタ装置１において、帯状の被切断部材の切断幅を変える場合には刃物ホルダーユニット２を軸線方向に移動しなければならない。そのため、移動可能な刃物ホルダーユニット２の従来技術として、たとえば特許文献１に開示されたものがある。これは、図７及び図８に示すようにホルダー４の外周面と内周面とを貫通するスリット３０を形成し、軸固定ボルト６でスリット３０を締付けてホルダー４の内径を減少させ、回転軸に刃物ホルダーユニット２を固定するようにしたものである。 By the way, in the slitter apparatus 1 as described above, when changing the cutting width of the band-shaped member to be cut, the blade holder unit 2 must be moved in the axial direction. Therefore, as a prior art of the movable blade holder unit 2, there is one disclosed in Patent Document 1, for example. As shown in FIGS. 7 and 8, a slit 30 is formed through the outer peripheral surface and the inner peripheral surface of the holder 4, and the inner diameter of the holder 4 is reduced by tightening the slit 30 with the shaft fixing bolt 6. The blade holder unit 2 is fixed to the shaft.
また、押え蓋５には、ホルダー４に形成されたスリット３０と同じ位置にスリット３５が形成されている。これは、軸固定ボルト６を締め付けたり緩めたりすることよってホルダー４のスリット３０の幅が拡縮するので、ホルダー４に固定された押え蓋５のスリット３５の幅もホルダー４と一体で拡縮する必要があるためである。 Further, a slit 35 is formed in the presser lid 5 at the same position as the slit 30 formed in the holder 4. This is because the width of the slit 30 of the holder 4 is expanded or contracted by tightening or loosening the shaft fixing bolt 6, so that the width of the slit 35 of the presser lid 5 fixed to the holder 4 needs to be expanded or contracted integrally with the holder 4. Because there is.
この方法は、軸固定ボルト６を締めたり緩めたりする作業をスリッタ装置１の正面から行うことができるので、刃物ホルダーユニット２を軸線方向に移動させるのが容易であることから、被切断部材の切断幅を自由に変更する方法として一般的に用いられている。 In this method, since the work of tightening or loosening the shaft fixing bolt 6 can be performed from the front of the slitter device 1, it is easy to move the blade holder unit 2 in the axial direction. Generally used as a method of freely changing the cutting width.
ところが、特許文献１の刃物ホルダーユニットの場合、図８及び図９に示すようにスリット３０によってホルダー４の外周面４ｃと内周面４ｂとが分断されているため、ホルダー４自体が持つ内部応力や、スリット３０を形成する際の加工応力等によって、たとえホルダー４の加工精度を上げたとしても、スリット３０の両面に軸線方向のズレが発生してしまうことがあった。また、軸固定ボルト６を締付けて回転軸に刃物ホルダーユニット２を固定する際も、軸固定ボルト６の締め付けトルクによって軸線方向のズレが発生してしまうことがあった。 However, in the case of the blade holder unit of Patent Document 1, since the outer peripheral surface 4c and the inner peripheral surface 4b of the holder 4 are divided by the slit 30 as shown in FIGS. Even if the processing accuracy of the holder 4 is increased due to processing stress or the like when the slit 30 is formed, the axial displacement may occur on both surfaces of the slit 30 in some cases. Further, when the shaft fixing bolt 6 is tightened and the blade holder unit 2 is fixed to the rotating shaft, the axial displacement may occur due to the tightening torque of the shaft fixing bolt 6.
より詳しくは、軸固定ボルト６を締め付けていくと、図１０−ａに示したように矢印で示した軸線方向に力が働くことで、２点鎖線で示した位置から実線で示した位置にずれたり、図１０−ｂに示すように矢印で示した方向に力が働くことで捩れをおこしたりする。これによってホルダー４に保持された丸刃３の刃先にはスラスト振れが発生するようになり、丸刃３の刃先側面と下丸刃２１の刃先側面とのスキマ或いは接触圧力の円周方向におけるムラが生じることになる。 More specifically, when the shaft fixing bolt 6 is tightened, a force acts in the axial direction indicated by the arrow as shown in FIG. 10A, so that the position indicated by the two-dot chain line is changed to the position indicated by the solid line. As shown in FIG. 10B, the twisting is caused by the force acting in the direction indicated by the arrow. As a result, thrust runout occurs at the cutting edge of the round blade 3 held by the holder 4, and the clearance between the cutting edge side surface of the round blade 3 and the cutting edge side surface of the lower round blade 21 or unevenness in the circumferential direction of the contact pressure. Will occur.
このムラが大きいと以下のような問題が生じる。まず、丸刃３の刃先側面と下丸刃２１の刃先側面とのスキマが大きい範囲或いは接触圧力が低い範囲では十分な切断力を得ることができないので、シート材はちぎれるように切断されて切断粉が発生する。これは被切断物の切断品質に影響を及ぼす原因となる。次に、スキマが小さい範囲或いは接触圧力が高い範囲では刃先に部分的な磨耗（偏磨耗）が発生する。これは刃物の寿命が得られない原因となる。 If this unevenness is large, the following problems occur. First, since a sufficient cutting force cannot be obtained in a range where the clearance between the cutting edge side surface of the round blade 3 and the cutting edge side surface of the lower round blade 21 is large or in a range where the contact pressure is low, the sheet material is cut to be broken and cut. Powder is generated. This is a factor that affects the cutting quality of the workpiece. Next, in the range where the clearance is small or the contact pressure is high, partial wear (uneven wear) occurs on the cutting edge. This causes the life of the blade not to be obtained.
また、スリット３０を締め付けてホルダー４の内径を減少させるには、ある程度の締め付けトルクが必要なため、その締め付けトルクの加減によってスラスト振れを増大させる原因にもなっていた。このため、切断幅を変更する度に、夫々のホルダー４の軸固定ボルト６の締め付けを加減するなどして、スラスト振れが適正な範囲内に収まるよう再度調整し直さなければならなかった。 Further, in order to reduce the inner diameter of the holder 4 by tightening the slit 30, a certain amount of tightening torque is required, and this has been a cause of increasing thrust runout by adjusting the tightening torque. For this reason, every time the cutting width is changed, it has been necessary to readjust the shaft fixing bolt 6 of each holder 4 so that the thrust runout falls within an appropriate range.
本発明は、上述したような従来の刃物ホルダーユニットを有するスリッタ装置の欠点に鑑みてなされたものであり、切断幅の変更を繰り返し行っても刃先のスラスト振れが適正な範囲内に容易に収まることができる刃物ホルダーユニットを有するスリッタ装置を提供することを課題とする。 The present invention has been made in view of the drawbacks of the slitter device having the conventional blade holder unit as described above, and the thrust runout of the blade edge can be easily within an appropriate range even when the cutting width is repeatedly changed. It is an object of the present invention to provide a slitter device having a blade holder unit that can be used.
本発明は、前述の課題を解決するため、まず、丸刃が装着されて回転軸に嵌装される円筒状のホルダーと、丸刃をホルダーとで挟んで複数の保持ボルトでホルダーに保持する円筒状の押え蓋とを備えた刃物ホルダーユニットを有するスリッタ装置において、ホルダーには、内周面側と外周面側とに、軸線方向に貫通し、略半径方向に向かい他方の面側に到らない深溝を少なくとも１個以上交互に隣接して形成し、深溝の溝間を内周面側と外周面側とを繋ぐ連結部として、その連結部を軸線方向と直角な面内で弾性変形可能な肉厚になるように形成し、深溝の側面のうち深溝が隣接していない側面には、軸固定ボルトが螺合される雌ねじ孔を形成し、雌ねじ孔と対向する側面には、軸固定ボルトが挿入される通し孔を形成し、軸固定ボルトを締付けて連結部を弾性変形させることによってホルダーの内径を減少させ、刃物ホルダーユニットが回転軸に固定されるようにしたスリッタ装置とする。 In order to solve the above-mentioned problems, the present invention first holds a cylindrical holder that is fitted with a round blade and fitted on a rotating shaft, and the round blade is sandwiched between the holders and held by a plurality of holding bolts. In a slitter device having a blade holder unit having a cylindrical presser lid, the holder penetrates in the axial direction on the inner peripheral surface side and the outer peripheral surface side, and reaches the other surface side substantially in the radial direction. At least one or more deep grooves that are not adjacent to each other are formed alternately adjacent to each other, and the deep groove is elastically deformed in a plane perpendicular to the axial direction by connecting the inner peripheral surface side to the outer peripheral surface side. A female screw hole is formed on the side surface of the deep groove that is not adjacent to the deep groove, and a shaft fixing bolt is screwed into the side surface of the deep groove. Form a through hole into which the fixing bolt is inserted, and tighten the shaft fixing bolt. Only reduces the inner diameter of the holder by elastically deforming the connecting portion, cutter holder unit and slitter apparatus that is fixed to the rotary shaft.
これにより、ホルダーの内周面と外周面は切断されることなく繋がっているので、ホルダー単体での軸線方向のズレは無くなり、軸固定ボルトを締め付けた際にズレが発生したとしても小さく抑えることができるようになる。 As a result, the inner peripheral surface and the outer peripheral surface of the holder are connected without being cut, so there is no axial displacement of the holder alone, and even if a displacement occurs when tightening the shaft fixing bolt, keep it small. Will be able to.
また、押え蓋には、内周面側と外周面側を貫通するスリットを形成して、ホルダーの深溝と押え蓋のスリットとを保持ボルトの同一ボルト間で円周方向に位相をずらして配設することを特徴とする請求項１に記載のスリッタ装置とする。 In addition, the presser lid is formed with slits that penetrate the inner and outer peripheral surfaces, and the deep groove of the holder and the slit of the presser lid are arranged with a phase shift in the circumferential direction between the same bolts of the holding bolts. The slitter device according to claim 1, wherein the slitter device is provided.
これにより、ホルダーの深溝は押え蓋のスリットの無い剛性のある部分で押えられるので、ホルダーの軸線方向のズレを押え蓋でも抑えることができるようになる。 As a result, the deep groove of the holder is pressed by a rigid portion without a slit of the presser lid, so that the shift in the axial direction of the holder can be suppressed even by the presser lid.
また、押え蓋には、内周面側と外周面側とに、軸線方向に貫通し、略半径方向に向かい他方の面側に到らない深溝を少なくとも１個以上交互に隣接して形成し、押え蓋の深溝の溝間を内周面側と外周面側とを繋ぐ連結部として、その連結部を軸線方向と直角な面内で弾性変形可能な肉厚になるように形成し、ホルダーの深溝と押え蓋の深溝とは、同一位置または同一保持ボルト間で円周方向に位相をずらして配設することを特徴とする請求項１に記載のスリッタ装置とする。 The presser lid is formed with at least one deep groove alternately adjacent to the inner peripheral surface side and the outer peripheral surface side in the axial direction and extending substantially in the radial direction and not reaching the other surface side. The connection between the deep grooves of the presser lid is a connecting portion that connects the inner peripheral surface side and the outer peripheral surface side, and the connecting portion is formed to have a thickness that can be elastically deformed in a plane perpendicular to the axial direction. 2. The slitter device according to claim 1, wherein the deep groove and the deep groove of the presser cover are disposed at the same position or between the same holding bolts with a phase shifted in the circumferential direction.
これにより、ホルダー及び押え蓋の内周面と外周面は切断されることなく繋がっているので、更に軸線方向のズレを小さく抑えることができるようになる。 Thereby, since the inner peripheral surface and the outer peripheral surface of the holder and the presser lid are connected without being cut, it is possible to further suppress the deviation in the axial direction.
また、丸刃が装着されて回転軸に嵌装される円筒状のホルダーと、丸刃をホルダーとで同心円状に挟んで複数の保持ボルトでホルダーに保持する円筒状の押え蓋と、を備えた刃物ホルダーユニットを有するスリッタ装置において、ホルダーには、内周面側と外周面側を貫通するスリットを形成し、スリットの一方の側面に軸固定ボルトが螺合する雌ねじ孔を形成し、他方の側面に軸固定ボルトが挿入される通し孔を形成し、押え蓋には、内周面側と外周面側を貫通するスリットを形成し、ホルダーのスリットと押え蓋のスリットとは、保持ボルトの同一ボルト間で円周方向に位相をずらして配設し、軸固定ボルトを締め付けることで、ホルダーのスリットを変形させてホルダーの内径を減少させ、刃物ホルダーユニットを回転軸に固定されるようにしたスリッタ装置とする。 In addition, a cylindrical holder fitted with a round blade and fitted to the rotating shaft, and a cylindrical presser lid that holds the round blade concentrically with the holder and holds the holder with a plurality of holding bolts. In the slitter device having the blade holder unit, the holder is formed with a slit penetrating the inner peripheral surface side and the outer peripheral surface side, and a female screw hole into which the shaft fixing bolt is screwed is formed on one side surface of the slit. A through hole into which the shaft fixing bolt is inserted is formed on the side surface, and a slit that penetrates the inner peripheral surface side and the outer peripheral surface side is formed in the presser lid. The slit of the holder and the slit of the presser lid are the holding bolts The same bolts are arranged out of phase in the circumferential direction, and by tightening the shaft fixing bolt, the holder slit is deformed to reduce the inner diameter of the holder, and the blade holder unit is fixed to the rotating shaft. And Unishi was slitter.
内周面側と外周面側を貫通するスリットであっても、ホルダーと押え蓋のスリットを、保持ボルトの同一ボルト間で円周方向に位相をずらして配設することで、ホルダーのスリットが押え蓋のスリットの無い剛性のある部分で押えられるので、ホルダーの軸線方向のズレを抑えることが出来るようになる。 Even if it is a slit that penetrates the inner peripheral surface side and outer peripheral surface side, the slits of the holder and the presser lid are arranged with a phase shift in the circumferential direction between the same bolts of the holding bolts. Since the presser lid can be held by a rigid part without slits, the holder can be prevented from shifting in the axial direction.
本発明によれば、丸刃の刃先のスラスト振れが適正な範囲内に収められるようになり、丸刃の刃先側面と下丸刃の刃先側面とのスキマ或いは接触圧力を適正に保つことができるようになるので、刃物の寿命が得られ、切断された被切断部材の品質も維持されるようになる。 According to the present invention, the thrust runout of the cutting edge of the round blade can be accommodated within an appropriate range, and the clearance or contact pressure between the cutting edge side surface of the round blade and the cutting edge side surface of the lower round blade can be properly maintained. As a result, the life of the blade is obtained, and the quality of the cut member to be cut is also maintained.

次に、刃物ホルダーユニット２の組立て及びスリッタ装置１の組立てについて、丸刃３の刃先側面と下丸刃２１の刃先側面とが所定の接触圧力を保つよう調整され組立てられる場合で説明する。 Next, the assembly of the blade holder unit 2 and the assembly of the slitter device 1 will be described in the case where the blade tip side surface of the round blade 3 and the blade tip side surface of the lower round blade 21 are adjusted and assembled so as to maintain a predetermined contact pressure.
刃物ホルダーユニット２の組立は、まず、ホルダー４の段部４ａに皿バネ２５と丸刃３を装着する。その後、溝部４０と押え蓋５の溝部５０とを保持ボルト７ａと保持ボルト７ｂとの同一ボルト間に配置させて、ホルダー４と押え蓋５とで丸刃３及び皿バネ２５を挟み込んで、保持ボルト７で保持する。これにより、刃物ホルダーユニット２が組立てられる。 To assemble the blade holder unit 2, first, the disc spring 25 and the round blade 3 are attached to the step 4 a of the holder 4. Thereafter, the groove 40 and the groove 50 of the presser lid 5 are arranged between the same bolts of the holding bolt 7a and the holding bolt 7b, and the round blade 3 and the disc spring 25 are sandwiched between the holder 4 and the presser lid 5 and held. Hold with bolts 7. Thereby, the blade holder unit 2 is assembled.
第２回転軸２０には、予め切断幅と切断条数に応じた下丸刃２１とスペーサ２２（２２ａ、２２ｂ、２２ｃ）が装着され、第２回転軸２０のフランジ部２３とナット２４によって軸線方向に締付けられて固定されている。下丸刃２１とスペーサ２２ａの軸線方向の寸法は、帯状の被切断部材の切断幅の基準となるので、要求される切断幅の精度に応じて精密に加工されている。尚、切断幅を変更する場合は、例えば特開２００８-０４４０７１号公報に記載の２分割スペーサ等を用いることによって、第２回転軸２０をスリッタ装置１から取り外すことなく、スペーサ２２を取り外し、違う幅のスペーサ２２と交換することができるようにしている。 A lower round blade 21 and spacers 22 (22a, 22b, 22c) corresponding to the cutting width and the number of cutting strips are mounted on the second rotating shaft 20 in advance, and the axis line is formed by the flange portion 23 and the nut 24 of the second rotating shaft 20. It is fastened in the direction and fixed. Since the dimension of the lower round blade 21 and the spacer 22a in the axial direction is a reference for the cutting width of the band-shaped member to be cut, it is precisely processed according to the required cutting width accuracy. When changing the cutting width, for example, by using a two-part spacer described in JP 2008-040771 A, the spacer 22 is removed without removing the second rotating shaft 20 from the slitter device 1. It is possible to replace the spacer 22 with a width.

Next, the blade holder unit 2 is moved in the axial direction so that the side surface of the round blade 3 and the side surface of the lower round blade 21 come into contact with each other, and the shaft fixing bolt 6 is temporarily tightened so that a predetermined contact pressure is obtained. adjust. When the contact pressure appropriate for cutting is obtained, the shaft fixing bolt 6 is tightened to fix the blade holder unit 2 to the first rotating shaft 10.
この場合において、ホルダー４の内周面４ｂと外周面４ｃとは連結部４０eによって切断されることなく繋がっているので、軸固定ボルト６を締付けていって溝部４０で軸線方向のズレが発生したとしても少なくて済む。また、連結部４０eが板バネ状に弾性変形できるように、溝４０ａと溝４０ｂを隣接させ、底部４０ｃ及び底部４０ｄを僅かに残して形成している。これにより、軸固定ボルト６を緩める時には連結部４０eの板バネの反発力でホルダー４の内径が広がって元に戻るので、刃物ホルダーユニット２の軸線方向の移動がスムーズに行えるようになる。 In this case, since the inner peripheral surface 4b and the outer peripheral surface 4c of the holder 4 are connected to each other without being cut by the connecting portion 40e, the shaft fixing bolt 6 is tightened and the axial deviation occurs in the groove portion 40. Even less. Further, the groove 40a and the groove 40b are adjacent to each other so that the connecting portion 40e can be elastically deformed into a leaf spring shape, and the bottom portion 40c and the bottom portion 40d are left slightly. As a result, when the shaft fixing bolt 6 is loosened, the inner diameter of the holder 4 expands and returns to its original state due to the repulsive force of the leaf spring of the connecting portion 40e, so that the blade holder unit 2 can move smoothly in the axial direction.
また、押え蓋５も内周面５ａと外周面５ｂとが連結部５０eによって切断されることなく繋がっているので、軸線方向のズレが少なくて済む。また、ホルダー４の溝部４０と押え蓋５の溝部５０とを保持ボルト７ａと保持ボルト７ｂとの同一ボルト間で円周方向に位相をずらして配置することで、ホルダー４の溝部４０は押え蓋５の溝部５０を避けた剛性のある部分で押えることができる。これによっても軸線方向のズレをより少なく抑えることができるようになる。また、連結部５０eが板バネ状に弾性変形できるように、溝５０ａと溝５０ｂを隣接させ、底部５０ｃ及び底部５０ｄを僅かに残して形成している。これにより、ホルダー４の連結部４０eと同様、軸固定ボルト６を緩める時に連結部５０eの板バネの反発力で押え蓋５の内径が広がって元に戻るので、刃物ホルダーユニット２の軸線方向の移動がスムーズに行えるようになる。 In addition, since the presser lid 5 is connected to the inner peripheral surface 5a and the outer peripheral surface 5b without being cut by the connecting portion 50e, the displacement in the axial direction can be reduced. Further, the groove portion 40 of the holder 4 and the groove portion 50 of the presser lid 5 are arranged in the circumferential direction out of phase with each other between the same bolts of the holding bolt 7a and the holding bolt 7b, so that the groove portion 40 of the holder 4 becomes the presser lid. 5 can be pressed by a rigid portion that avoids the groove portion 50. This also makes it possible to suppress the deviation in the axial direction. Further, the groove 50a and the groove 50b are adjacent to each other so that the connecting portion 50e can be elastically deformed into a leaf spring shape, and the bottom 50c and the bottom 50d are left slightly. As a result, like the connecting portion 40e of the holder 4, when the shaft fixing bolt 6 is loosened, the inner diameter of the presser cover 5 is expanded and returned to the original by the repulsive force of the leaf spring of the connecting portion 50e. You can move smoothly.
このことから、刃物ホルダーユニット２を移動させて切断幅の変更を繰り返し行っても、丸刃３の刃先のスラスト振れが適正な範囲内に安定して収められるようになり、丸刃３の刃先側面と下丸刃２１の刃先側面との接触圧力を適正に保つよう調整することが容易にできるようになるので、刃物の寿命が得られ、切断された被切断部材の品質も維持されるようになる。 From this, even if the blade holder unit 2 is moved and the cutting width is repeatedly changed, the thrust runout of the cutting edge of the round blade 3 can be stably stored within an appropriate range. Since the contact pressure between the side surface and the blade tip side surface of the lower round blade 21 can be easily adjusted, the life of the blade can be obtained, and the quality of the cut member can be maintained. become.
尚、本実施形態では、溝部４０と溝部５０の溝幅及び溝の底部４０ｃ、４０ｄ、５０ｃ、５０ｄの寸法を１〜２ｍｍとしたが、これに限るものではなく、軸固定ボルト６を締め付けても丸刃３の刃先のスラスト振れが適正な範囲内に収まる寸法であればよい。また、溝の数をホルダー４及び押え蓋５共に内周面側と外周面側とに各1個ずつとしたが、複数個交互に形成してもよい。 In this embodiment, the groove width of the groove 40 and the groove 50 and the dimensions of the groove bottoms 40c, 40d, 50c, 50d are 1 to 2 mm. However, the present invention is not limited to this, and the shaft fixing bolt 6 is tightened. As long as the thrust runout of the cutting edge of the round blade 3 falls within an appropriate range. The number of grooves is one for each of the inner peripheral surface side and the outer peripheral surface side of both the holder 4 and the presser lid 5, but a plurality of grooves may be alternately formed.
また、本実施形態では、ホルダー４及び押え蓋５共に内周面側と外周面側とに１ケ所ずつ、一方の面に到らない深溝が形成されている場合について説明したが、ホルダーのみに内周面側と外周面側とに１ケ所ずつの一方の面に到らない深溝を形成し、押え蓋には図４に示すように、内周面側と外周面側とを貫通したスリットを形成して、保持ボルトの同一ボルト間で円周方向に位相をずらして配設させてもよい。丸刃３の刃先のスラスト振れ精度が比較的緩く設定されている場合は、これを用いることで、加工費を安価に抑えることができる。 In the present embodiment, the holder 4 and the presser lid 5 have been described with respect to the case where a deep groove that does not reach one surface is formed on the inner peripheral surface side and the outer peripheral surface side. A deep groove that does not reach one surface on each of the inner peripheral surface side and the outer peripheral surface side is formed, and a slit penetrating the inner peripheral surface side and the outer peripheral surface side as shown in FIG. And may be arranged with the phase shifted in the circumferential direction between the same bolts of the holding bolts. When the thrust runout accuracy of the cutting edge of the round blade 3 is set to be relatively loose, the processing cost can be reduced by using this.
また、丸刃３の刃先のスラスト振れ精度が更に緩く設定されている場合は、図８で示したホルダーと図４で示した押え蓋のように、どちらも内周面側と外周面側とを貫通したスリットを形成して、保持ボルトの同一ボルト間で円周方向に位相をずらして配設させてもよい。丸刃３の刃先のスラスト振れ精度が更に緩く設定されている場合は、これを用いることで、加工費をより安価に抑えることができる。 Further, when the thrust runout accuracy of the cutting edge of the round blade 3 is set to be looser, both the inner peripheral surface side and the outer peripheral surface side, like the holder shown in FIG. 8 and the presser lid shown in FIG. May be formed so as to be shifted in the circumferential direction between the same bolts of the holding bolts. When the thrust runout accuracy of the cutting edge of the round blade 3 is set to be more loose, by using this, the processing cost can be further reduced.
また、本実施形態では、刃物ホルダーユニット２の組立て及びスリッタ装置の組立てについて、丸刃３の刃先側面と下丸刃２１の刃先側面とが皿バネ２５によって所定の接触圧力を保つよう調整されて組立てられる場合で記述したが、丸刃３の刃先側面と下丸刃２１の刃先側面とが所定のスキマを保つよう調整されて組立てられる場合で、刃物ホルダーユニット２に皿バネ２５を用いる場合或いは皿バネを用いずに丸刃３をホルダー４と押え蓋５で直接挟み込む場合も同様の効果を得ることができる。 Further, in this embodiment, the blade holder unit 2 and the slitter device are assembled so that the blade tip side surface of the round blade 3 and the blade tip side surface of the lower round blade 21 are adjusted by the disc spring 25 to maintain a predetermined contact pressure. Although described in the case of assembling, the case where the blade side surface of the round blade 3 and the blade side surface of the lower round blade 21 are adjusted and assembled so as to maintain a predetermined clearance, and the disc holder 25 is used in the blade holder unit 2 or The same effect can be obtained when the round blade 3 is directly sandwiched between the holder 4 and the presser lid 5 without using a disc spring.
