JP 2006-2725425 A

上記した従来の糊付機用スリッターでは、下刃を駆動する下刃駆動軸は、スリッターの左右両端部に別体として軸受された左右下刃駆動軸からなり、また、上刃は駆動軸を有せず、バネにより下刃に圧接するようにしたので、上刃駆動軸の曲がりに起因する上刃の振れの発生を防止することができるため、切断ぶれが生ぜずスムーズに壁紙の切断を行うことができ、また、上刃をバネに抗して下刃から離反する方向に移動させることにより、下刃の取り外しを容易に行うことができ、また、下刃駆動板及び下刃回転軸の嵌合穴の内径を下刃駆動軸の軸径より僅か大きく設定することで、下刃駆動軸が振動した場合であっても、下刃駆動板及び下刃回転軸は、下刃駆動軸に対して直角方向に移動できるため、下刃駆動軸の振動を吸収し、下刃を下刃駆動軸の影響を受けずに安定して回転することができ、下刃駆動軸の曲がりに起因する下刃の振れの発生を防止することができるという作用を有するが、軸方向のガタ（スキマ）を極小に抑える必要があり、面接触する構成である為、駆動板を駆動軸に対してラジアル方向（軸に垂直な方向）にスライドすることが出来ず、駆動軸と回転軸に芯ズレがあった場合、駆動軸が駆動板を無理矢理回転させようとする力が働き、その結果、軸受けケース全体が振動し、駆動板を駆動軸に対し、スムーズにスライドさせる為には、両者の摩擦係数を極力少なくする必要があり、接触面を機械加工で表面粗さを抑えたり、表面処理等が必要となる為、コスト増になるという課題を有していた。   In the conventional slitter for pasting machine, the lower blade drive shaft for driving the lower blade is composed of left and right lower blade drive shafts that are separately supported at the left and right ends of the slitter, and the upper blade is driven by the drive shaft. Since it is pressed against the lower blade by a spring, it is possible to prevent the upper blade from shaking due to the bending of the upper blade drive shaft. The lower blade can be easily removed by moving the upper blade away from the lower blade against the spring, and the lower blade driving plate and the lower blade rotating shaft can be removed. Even if the lower blade drive shaft vibrates, the lower blade drive plate and the lower blade rotation shaft are used as the lower blade drive shaft even if the inner diameter of the fitting hole is set to be slightly larger than the shaft diameter of the lower blade drive shaft. Because it can move in the direction perpendicular to the It has the effect of being able to rotate stably without being influenced by the blade drive shaft and preventing the lower blade from being shaken due to the bending of the lower blade drive shaft. It is necessary to keep the clearance between them to a minimum, and because the structure is in surface contact, the drive plate cannot be slid in the radial direction (perpendicular to the axis) with respect to the drive shaft. If there is a deviation, the drive shaft will force the drive plate to rotate forcefully. As a result, the entire bearing case vibrates, and in order to slide the drive plate relative to the drive shaft smoothly, The friction coefficient must be reduced as much as possible, and the contact surface must be machined to reduce the surface roughness or surface treatment, which increases the cost.

前記した従来の糊付機用スリッターにおいて、駆動軸と回転軸に芯ズレがあった場合に軸受けケースに振動が発生する理由について説明する。   The reason why vibration occurs in the bearing case when the drive shaft and the rotation shaft are misaligned in the above-described conventional slitting machine for a pasting machine will be described.

図１２は特許文献１に示すスリッターにおいて、駆動軸７に芯振れが無いが、駆動軸７の回転中心と回転軸２０の中心に芯ズレが生じたまま組み立てた場合の１例（回転軸中心と駆動板の六角中心より上部に駆動軸の回転中心がある場合）を示す。   FIG. 12 shows an example of the slitter shown in Patent Document 1 in which the drive shaft 7 does not run out but is assembled with the center of rotation of the drive shaft 7 and the center of the rotation shaft 20 being misaligned (center of rotation shaft). And when the rotation center of the drive shaft is above the hexagonal center of the drive plate).

図１３は図１２のような状態において、例えば回転軸２０中心と駆動軸７の回転中心の組立芯ズレが０．５ｍｍの場合に、回転軸を回転させた時の動きを表している。   FIG. 13 shows the movement when the rotary shaft is rotated in the state shown in FIG. 12, for example, when the assembly center misalignment between the center of the rotary shaft 20 and the rotational center of the drive shaft 7 is 0.5 mm.

図１３において、駆動軸７を約２．０度回転させると駆動板２１が回転し、すぐに回転軸２０に取り付けられる回転軸カラー２４と駆動板２１の係合穴２３が接触する。その状態から駆動軸７を１５度ずつ順次回転させ、１８０度まで回転させた時の状態を表している。回転軸カラー２４と駆動板２１の係合穴２３の接触点は、回転するにつれて徐々にずれていき、７５度回転した時点から９０度回転した時点の間で接触点１から接触点２へ移り、別の回転軸カラー２４ｂと駆動板２１の係合穴２３ｂに移動している。   In FIG. 13, when the drive shaft 7 is rotated about 2.0 degrees, the drive plate 21 rotates, and the rotary shaft collar 24 attached to the rotary shaft 20 immediately contacts the engagement hole 23 of the drive plate 21. In this state, the drive shaft 7 is sequentially rotated by 15 degrees and is rotated to 180 degrees. The contact point between the rotary shaft collar 24 and the engagement hole 23 of the drive plate 21 gradually shifts as it rotates, and moves from the contact point 1 to the contact point 2 between the point of rotation of 75 degrees and the point of rotation of 90 degrees. The rotary shaft collar 24b is moved to the engagement hole 23b of the drive plate 21.

図１４に回転軸カラー２４と駆動板２１の係合穴２３の接触点が別の回転軸カラー２４ｂと駆動板２１の係合穴２３の直線部２３ｂに移動する状態を示す。接触点１においては、７５度まで駆動軸７の回転を伝えていた回転軸カラー２４と駆動板２１の係合穴２３は回転軸中心から１４．００ｍｍの位置で接しており、また、回転を伝える角度は１０３．６６度になっている。   FIG. 14 shows a state where the contact point between the rotation shaft collar 24 and the engagement hole 23 of the drive plate 21 moves to another rotation shaft collar 24 b and the straight portion 23 b of the engagement hole 23 of the drive plate 21. At the contact point 1, the rotation shaft collar 24 that has transmitted the rotation of the drive shaft 7 to 75 degrees is in contact with the engagement hole 23 of the drive plate 21 at a position of 14.00 mm from the center of the rotation shaft. The transmission angle is 103.66 degrees.

次に接触点２においては、駆動軸の回転を伝える回転軸カラー２４ｂと駆動板２１の係合穴２３ｂは回転軸中心から１６．５８ｍｍの位置で接し、また、回転を伝える角度は５３．８度に変化している。   Next, at the contact point 2, the rotation shaft collar 24b for transmitting the rotation of the drive shaft and the engagement hole 23b of the drive plate 21 are in contact with each other at a position of 16.58 mm from the center of the rotation shaft, and the angle for transmitting the rotation is 53.8. Has changed.

このように、接触点１から接触点２へと駆動板の係合穴から回転軸カラーへの力の伝達距離と回転を伝える角度が一瞬に変化するため、駆動板の回転によるブレが発生し、その結果、上刃、下刃を軸受けする軸受けケース全体が振動するという課題を有していた。   As described above, since the transmission distance of the force from the engagement hole of the drive plate to the rotary shaft collar and the angle for transmitting the rotation change instantaneously from the contact point 1 to the contact point 2, blurring due to the rotation of the drive plate occurs. As a result, the entire bearing case for bearing the upper blade and the lower blade vibrates.

糊付機本体の駆動に連動する上刃駆動軸及び下刃駆動軸により駆動する上刃及び下刃により壁紙を切断する糊付機用スリッターであって、下刃が固設され、下刃駆動軸が嵌挿される下刃中空回転軸と、前記下刃中空回転軸に等間隔で突設したカラーと、前記下刃駆動軸に連結し、前記カラーが接触するよう等間隔で設けられた係合穴を有する下刃駆動板を備え、前記係合穴は、下刃中空回転軸の中空穴径の半径と下刃駆動軸の半径の差により求められる長さ分前記カラーの外形寸法より大きい径の円の外周と下刃駆動軸の中心を結ぶ接線により規定される直線部を有し、前記下刃駆動軸と下刃中空回転軸間の芯振れ時に、前記カラーと係合穴の接触位置の回転中心からの長さ及び接触角度を一定にしたことを特徴とする。   Slitting machine for gluing machine that cuts wallpaper with upper and lower blades driven by upper and lower blade drive shafts that are linked to the drive of the gluing machine body. Lower blade is fixed and driven by lower blades. A lower blade hollow rotary shaft into which the shaft is inserted, a collar projecting at an equal interval from the lower blade hollow rotary shaft, and an engagement provided at equal intervals so as to contact the collar connected to the lower blade drive shaft A lower blade drive plate having a joint hole is provided, and the engagement hole is larger than the outer dimension of the collar by a length determined by the difference between the radius of the hollow hole diameter of the lower blade hollow rotary shaft and the radius of the lower blade drive shaft. A collar portion defined by a tangent line connecting the outer periphery of the circle of the diameter and the center of the lower blade drive shaft, and contact between the collar and the engagement hole at the time of runout between the lower blade drive shaft and the lower blade hollow rotary shaft The length of the position from the rotation center and the contact angle are made constant.

本発明の糊付機用スリッターは、下刃駆動板に設けた係合穴の形状を、下刃中空回転軸の中空穴径の半径と下刃駆動軸の半径の差により求められる長さ分下刃中空回転軸に固設したカラーの外形寸法より大きい径の円の外周と下刃駆動軸の中心を結ぶ接線により規定される直線部を有する形状とし、前記下刃駆動軸と下刃中空回転軸間の芯振れ時に、前記カラーと係合穴の接触位置の回転中心からの長さ及び接触角度を一定にしたことにより、従来の糊付機用スリッターの課題であった、駆動軸と回転軸に芯振れがあった場合や駆動軸に芯振れがあった場合に下刃駆動板の回転に生ずる回転ブレに起因する軸受けケースの振動を防止することができる。   The slitter for a gluing machine according to the present invention has the shape of the engagement hole provided in the lower blade drive plate by the length determined by the difference between the radius of the hollow hole diameter of the lower blade hollow rotary shaft and the radius of the lower blade drive shaft. The lower blade drive shaft and the lower blade hollow have a shape having a straight portion defined by a tangent line connecting the outer periphery of a circle having a diameter larger than the outer dimension of the collar fixed to the lower blade hollow rotary shaft and the center of the lower blade drive shaft. The drive shaft, which was a problem of the conventional slitter for pasting machines, by making the length and contact angle from the rotation center of the contact position of the collar and the engagement hole constant during the runout between the rotation shafts, It is possible to prevent vibration of the bearing case due to rotation blur caused by rotation of the lower blade drive plate when the rotation shaft has runout or when the drive shaft has runout.

Explained.

図５は、下刃駆動板２１に設ける係合穴２３の形状を説明する断面図である。下刃駆動軸７と下刃駆動板２１間には下刃駆動板２１がスラスト方向に僅かにスライドできる、例えばスラスト方向０．１ｍｍ程度の隙間を設け、下刃中空回転軸２０に固設された回転軸カラー２４と当接する下刃駆動板２１に設けた係合穴２３の形状を、前記回転軸カラー２４の外形寸法より、後記する下刃駆動軸２１の芯振れ許容範囲分大きい径を有する仮想円の外周と下刃駆動軸２１の中心を結ぶ接線により規定される直線部２３ａを有する構成としている。   FIG. 5 is a cross-sectional view illustrating the shape of the engagement hole 23 provided in the lower blade drive plate 21.

For example, the hollow hole diameter of the lower blade hollow rotary shaft 20 is 15 mm. When the outer shape is 14 mm, it is obtained by (15-14) ÷ 2 = 0.5.

また、図６には前記直線部２３ａを有する係合穴２３を備えた下刃駆動板２１と下刃駆動軸７に芯振れが生じた場合の１例（回転軸中心より上部に下刃駆動軸と下刃駆動板の六角中心がある場合）を示す。   FIG. 6 shows an example of the case where the lower blade driving plate 21 having the engagement hole 23 having the linear portion 23a and the lower blade driving shaft 7 run out (lower blade driving above the rotation axis center). (When there is a hexagonal center of the shaft and lower blade drive plate).

図７は、例えば０．５ｍｍの下刃駆動軸芯振れが有った場合に、下刃駆動軸７を回転させた時の動作を示す。図７において、下刃駆動軸７を約２．６度回転させると下刃駆動板２１が回転し、すぐに下刃中空回転軸２０に取り付けられる回転軸カラー２４と下刃駆動板２１の係合穴２３の直線部２３ａが接触する。   FIG. 7 shows an operation when the lower blade drive shaft 7 is rotated, for example, when there is a runout of the lower blade drive shaft of 0.5 mm. In FIG. 7, when the lower blade driving shaft 7 is rotated about 2.6 degrees, the lower blade driving plate 21 is rotated, and the rotary shaft collar 24 and the lower blade driving plate 21 that are immediately attached to the lower blade hollow rotating shaft 20 are engaged. The straight portion 23a of the joint hole 23 comes into contact.

その状態から下刃駆動軸７を１５度ずつ回転させ、１８０度まで回転させても係合穴２３は前記した直線部２３ａを有しているので、回転軸カラー２４と下刃駆動板２１の係合穴２３の接触点は、常に直線上同位置で、回転中心からの直線距離及び回転伝達角度は一定であるため下刃駆動板２１の回転に起因する回転ブレは発生せず、従って、軸受けケース１５には芯ズレに起因する振動は生じない。   Even if the lower blade drive shaft 7 is rotated by 15 degrees from that state and rotated to 180 degrees, the engagement hole 23 has the linear portion 23a described above, so the rotation shaft collar 24 and the lower blade drive plate 21 The contact point of the engagement hole 23 is always at the same position on a straight line, and the linear distance from the rotation center and the rotation transmission angle are constant, so that no rotation blur due to the rotation of the lower blade drive plate 21 occurs. The bearing case 15 is free from vibration due to misalignment.

次に、図８には、下刃駆動軸７に芯振れが無いが、下刃駆動軸７の回転中心と回転軸中心に芯ズレを生じさせて組み立てした場合の１例（回転軸中心と駆動軸と駆動板の六角中心より上部に駆動軸の回転中心がある場合）を示す。   Next, FIG. 8 shows an example in which the lower blade drive shaft 7 does not run out of core but is assembled by causing a misalignment between the rotation center of the lower blade drive shaft 7 and the rotation shaft center (the rotation shaft center and (When the rotation center of the drive shaft is above the hexagon center of the drive shaft and drive plate).

図９は、例えば０．５ｍｍの回転軸中心と下刃駆動軸７の回転中心の組立芯ズレが有った場合に、下刃中空回転軸２０を回転させた時の動作を示す。下刃駆動軸７を約２．５度回転させると下刃駆動板２１が回転し、すぐに下刃中空回転軸２０に取り付けられる回転軸カラー２４と下刃駆動板２１の係合穴２３の直線部２３ａが接触する。   FIG. 9 shows an operation when the lower blade hollow rotary shaft 20 is rotated when there is an assembly misalignment between the rotation shaft center of 0.5 mm and the rotation center of the lower blade drive shaft 7, for example. When the lower blade drive shaft 7 is rotated about 2.5 degrees, the lower blade drive plate 21 is rotated, and the rotary shaft collar 24 and the engagement hole 23 of the lower blade drive plate 21 are immediately attached to the lower blade hollow rotary shaft 20. The linear part 23a contacts.

その状態から下刃駆動軸７を１５度ずつ回転させ、１８０度まで回転させても回転軸カラー２４は下刃駆動板２１の係合穴２３の直線部２３ａと接触したままであるが、１０５度回転した時点から１２０度回転した時点の間で接触点が接触点１から別の回転軸カラーと駆動板の係合穴２３の接触点２に移動する。   Even if the lower blade drive shaft 7 is rotated by 15 degrees from that state and rotated to 180 degrees, the rotary shaft collar 24 remains in contact with the linear portion 23a of the engagement hole 23 of the lower blade drive plate 21. The contact point moves from the contact point 1 to another contact point 2 of the engagement hole 23 of the drive plate between the contact point 1 and the point of rotation 120 degrees.

図１０に接触点が別の回転軸カラーと駆動板の係合穴に移動する瞬間の状態を示す。接触点１では、１０５度まで下刃駆動軸７の回転を伝達していた回転軸カラー２４と下刃駆動板２１の係合穴２３は回転軸中心から１４．６５ｍｍの位置で接し、また、回転を伝える角度は９０．９８度になっている。   FIG. 10 shows a state at the moment when the contact point moves to another rotation shaft collar and the engagement hole of the drive plate. At the contact point 1, the rotation shaft collar 24 that has transmitted the rotation of the lower blade drive shaft 7 to 105 degrees is in contact with the engagement hole 23 of the lower blade drive plate 21 at a position of 14.65 mm from the rotation shaft center. The angle for transmitting rotation is 90.98 degrees.

次に接触点１から接触点が移動した接触点２では、下刃駆動軸７の回転を伝達する回転軸カラー２４と下刃駆動板２１の係合穴２３は回転軸中心から接触点１と同じ１４．６５ｍｍの位置で接し、また、回転を伝える角度も同じ９０．９８度になっている。   Next, at the contact point 2 where the contact point has moved from the contact point 1, the rotation shaft collar 24 for transmitting the rotation of the lower blade drive shaft 7 and the engagement hole 23 of the lower blade drive plate 21 are connected to the contact point 1 from the rotation shaft center. The contact is made at the same 14.65 mm position, and the rotation transmission angle is also 90.98 degrees.

以上説明した通り、下刃駆動板２１の係合穴２３と回転軸カラー２４の接触点と回転中心からの距離は常に同じで、回転軸カラー２４と係合穴２３の接触点は、接触点１から接触点２に移動しているものの、接触点の回転中心からの直線距離は回転中心から、半径１４．６５の同一円周上にあり、変化は無く、また力のかかる方向も９０度にほとんど近い９０．９８度のままで変化無く、下刃駆動軸７の回転中心と回転軸中心にズレを生じさせたまま組み立てた場合にでも、下刃駆動板２１の回転に起因する回転ブレは発生せず、従って軸受けケース１５には組み立て芯ズレに起因する振動は生じない。   As described above, the contact point between the engagement hole 23 of the lower blade driving plate 21 and the rotation shaft collar 24 and the distance from the rotation center are always the same, and the contact point between the rotation shaft collar 24 and the engagement hole 23 is the contact point. Although moving from 1 to contact point 2, the linear distance from the rotation center of the contact point is on the same circumference with a radius of 14.65 from the rotation center, there is no change, and the direction in which the force is applied is also 90 degrees. Even when assembled with the difference between the rotation center of the lower blade drive shaft 7 and the center of the rotation shaft, the rotation blur caused by the rotation of the lower blade drive plate 21 remains unchanged at 90.98 degrees. Therefore, the bearing case 15 does not vibrate due to assembly misalignment.

本実施例において、係合穴と回転軸カラーは３個設けているが、図１１に示すように、等ピッチで２個の係合穴をそれぞれ対象位置に設けてもよい。また、円周方向が開口形状であってもよい。   In this embodiment, three engagement holes and three rotation shaft collars are provided. However, as shown in FIG. 11, two engagement holes may be provided at the target positions at equal pitches. Further, the circumferential direction may be an opening shape.

また、糊付機本体からの駆動を、下刃駆動軸を介して上刃駆動軸を駆動する構成として説明したが、上刃駆動軸を介して下刃駆動軸を駆動する構成としてもよい。   Further, the drive from the gluing machine main body has been described as the configuration in which the upper blade drive shaft is driven through the lower blade drive shaft, but the lower blade drive shaft may be driven through the upper blade drive shaft.
