Description

本発明は雑草等の刈払機用チップソーの研磨機と研磨方法に関する。     The present invention relates to a polishing machine and a polishing method for a tip saw for a brush cutter such as weeds.

従来、草刈用にエンジン駆動のチップソーを用いた刈払機が汎用されており、通常、市販品はチップソーの円板状の歯面とチップの天刃（先端の刃面）が直角をなしているが、本発明者において、それでは切れ味が短期間に鈍化しやすく、チップの天刃がチップソーの円板状の歯の下面となす角度を鋭角にしたほうが効果的であることがわかっている。そのようにするため、手作業による目立ては容易でなく煩雑であり、さりとてチップソーの新品との交換を頻繁におこなうこともできない。   Conventionally, a brush cutter using an engine-driven tip saw for mowing has been widely used. Usually, in a commercially available product, the disc-shaped tooth surface of the tip saw and the top blade (tip blade surface) of the tip form a right angle. However, in the present inventors, it has been found that the sharpness is easily blunted in a short period of time, and it is more effective to make the angle formed by the top edge of the tip and the lower surface of the disc-shaped tooth of the tip saw more acute. For this reason, manual sharpening is not easy and cumbersome, and the tip saw cannot be frequently replaced with a new one.

従来、チップソーの研磨機として特許文献１のごときものが提案されており、それによれば、チップソーが天刃研磨位置或いは腹刃研磨位置においてテーブルに着脱、かつ回転可能に支軸されていて、テーブルにはホルダーが回動可能に軸着されており、ホルダーにはディスクグラインダーが着脱可能に取着されていて、ディスクグラインダーには研磨ホイールが取着され、天刃研磨位置または腹刃研磨位置に軸支されている。そして、ディスクグラインダーに取着の研磨ホイールが天刃研磨位置に軸支されるチップソーの天刃、或いは腹刃の研磨位置に軸支されるチップソーの腹刃に当てられるようホルダーの位置決めを行うストッパーが存在している。また、テーブルには爪を軸着してバネの作用により一方向に回動できるように付勢し、チップソーの歯に当てられてチップソーが一方向にのみ回動できるようにされている研磨機が示されている。しかしながら、この研磨機は、天刃の横逃げ角或いは腹刃の横すくい角に応じて垂直方向内で研磨ホイールの向きを変え、チップソーの円板状の歯面と直交する位置でチップの天刃を研磨するというものであり、そのようにしてチップの天刃等を研磨するものは、本発明が意図する、研磨ホイールでチップの天刃がチップソーの円板状の歯の下面と傾斜をなすように研磨するものとは全く異なるので、提案されている研磨機を本発明の研磨に応用することはできない。
特開平９−１５５７０１号 Conventionally, a tip saw polishing machine such as that disclosed in Patent Document 1 has been proposed. According to this, a tip saw is attached to and detached from a table at a top blade polishing position or a stomach blade polishing position, and is rotatably supported. A holder is pivotally attached to the holder, and a disc grinder is detachably attached to the holder, and a grinding wheel is attached to the disc grinder, so that it is in a top blade polishing position or a stomach blade polishing position. It is pivotally supported. A stopper for positioning the holder so that the grinding wheel attached to the disc grinder is applied to the top blade of the tip saw supported by the top blade polishing position or the tip saw abdomen blade supported by the polishing position of the belly blade. Is present. Also, a claw is pivotally attached to the table so that it can be rotated in one direction by the action of a spring and applied to the teeth of the tip saw so that the tip saw can rotate only in one direction. It is shown. However, this grinding machine changes the direction of the grinding wheel in the vertical direction according to the side clearance angle of the top blade or the side rake angle of the top blade, and the top of the tip is at a position orthogonal to the disc-shaped tooth surface of the tip saw. The blade is polished, and the tip top blade and the like are polished in this manner, and the tip top blade of the tip is inclined with the lower surface of the disc-like tooth of the tip saw in the polishing wheel as intended by the present invention. Since it is completely different from what is polished, the proposed polishing machine cannot be applied to the polishing of the present invention.
JP-A-9-155701

本発明は草刈の刈払機用チップソーの研磨機と研磨方法に関し、チップソーのチップの天刃をチップソーの円板状の歯の下面と任意の傾斜角度とすることができる研磨機と研磨方法を提供せんとするものである。   TECHNICAL FIELD The present invention relates to a tip saw polishing machine and a polishing method for a mowing brush cutter, and provides a polishing machine and a polishing method in which the top blade of the tip saw tip can be at an arbitrary inclination angle with the lower surface of the disc-like tooth of the tip saw. It is something to be done.

ここにおいて本発明者はチップソーの研磨機として、架台２に取付けたディスクグラインダー１とチップソー誘導板３とからなり、ディスクグラインダー１はその研磨用円板14が所定の高さで垂直方向に支持されていて、チップソー誘導板３は研磨用円板14に向かい前下がりに所定の傾斜角度をなし、チップソー誘導板３にはその板面に研磨用円板14と直交方向の縦長の溝４と、裏面に軸着されているチップソー誘導用のレバー６と、レバー６の作動により縦長の溝４の対向両縁に沿い自在に移動し得る台座（図示省略）とがあり、台座は横断面がＨ型をなし、両側に縦長の溝４の対向両縁と緩嵌する（ゆるやかにはめるの意）凹部を有し、台座の頂面にチップソー５が回動可能なようにチップソー５の取付孔と嵌合する円環が固定されていて、円環の中心にボルトが植設されておりそれに円環より大径のキャップを螺合して緊締し、チップソー５が回動可能なようにチップソーとの間隙を小にしてあり、レバー６開放時台座が、傾斜している縦長の溝４の上限に位置するよう台座にバネＡ８が付いており、レバー６には手元付近で交差し、先端付近に円柱突起11がある、バネＢ10付きの補助レバー９があり、また、レバー６には補助レバー９のバネＢ10による開放角度を制限する突起15があり、さらに、チップソー誘導板３の裏面に軸着している支持片16の先端にある円柱突起12がチップソー誘導板３の側縁に当接し、レバー６使用時、バネ13の作動によりチップソー５が時計反対方向に回動できるように付勢してあり、円柱突起12がチップソーの歯の彎曲18内に位置していることからなるチップソーの研磨機を見出すに至った。   In this case, the inventor comprises a disc grinder 1 attached to a gantry 2 and a tip saw guide plate 3 as a tip saw polishing machine. The disc grinder 1 has a polishing disc 14 supported vertically at a predetermined height. The tip saw guide plate 3 has a predetermined inclination angle toward the polishing disc 14 in a forward and downward direction, and the tip saw guide plate 3 has a vertically long groove 4 perpendicular to the polishing disc 14 on the plate surface. There is a tip saw guiding lever 6 pivotally attached to the back surface, and a pedestal (not shown) that can move freely along opposite edges of the longitudinal groove 4 by the operation of the lever 6. It has a mold, has recesses that loosely fit (oppositely fit) the opposite edges of the vertically long groove 4 on both sides, and a mounting hole for the tipsaw 5 so that the tipsaw 5 can be rotated on the top surface of the base. The mating ring is fixed A bolt is planted in the center of the ring, and a cap larger in diameter than the ring is screwed and tightened, and the gap with the tip saw is made small so that the tip saw 5 can rotate, and the lever 6 is opened. A spring A8 is attached to the pedestal so that the hour pedestal is positioned at the upper end of the inclined long groove 4, and the lever 6 intersects near the hand, and has a cylindrical protrusion 11 near the tip, with a spring B10. There is an auxiliary lever 9, and the lever 6 has a protrusion 15 that limits the opening angle of the auxiliary lever 9 by the spring B 10, and is further at the tip of the support piece 16 that is pivotally attached to the back surface of the tip saw guide plate 3. The cylindrical projection 12 abuts the side edge of the tip saw guide plate 3 and when the lever 6 is used, the tip saw 5 is urged by the action of the spring 13 so that the tip saw 5 can be rotated in the counterclockwise direction. Because it is located in I came to find the polishing machine of the chip saw.

また、チップソーの研磨方法として、上記によるチップソーの研磨機を用いて、補助レバー９を引き寄せたままレバー６を時計反対方向に若干回転して補助レバー９の円柱突起11をチップソー５の手近にある歯の彎曲18内に嵌め、補助レバー９を引き寄せたままレバー６をさらに時計反対方向に回転して、円柱突起12を嵌まっている歯の湾曲18内から隣接する時計方向の歯の彎曲18内に移動して嵌め、補助レバー９を放して補助レバー９の円柱突起11を歯の彎曲18内から外し、レバー６のみを研磨用円板14方向に押出してチップソー５のチップ17の天刃を作動中のディスクグラインダー１の研磨用円板14に当接して研磨してから、レバー６を元の位置に戻し、以上を繰り返すことからなるチップソーの研磨方法を見出すに至った。   As a tip saw polishing method, using the tip saw polishing machine described above, the lever 6 is slightly rotated counterclockwise while the auxiliary lever 9 is attracted so that the cylindrical protrusion 11 of the auxiliary lever 9 is close to the tip saw 5. Fit in the tooth curvature 18 and rotate the lever 6 further in the counterclockwise direction while pulling the auxiliary lever 9, and the curvature 18 of the adjacent clockwise tooth from the inside of the tooth curvature 18 in which the cylindrical protrusion 12 is fitted. Move and fit inside, release the auxiliary lever 9 to remove the cylindrical projection 11 of the auxiliary lever 9 from the inside of the tooth curvature 18, push only the lever 6 in the direction of the polishing disc 14, and the top blade of the tip 17 of the tip saw 5 Is brought into contact with the polishing disc 14 of the disc grinder 1 in operation, and then the lever 6 is returned to the original position, and the above method is repeated.

草刈の刈払機用チップソーのチップ17の刃面に対し研磨してチップソーの円板状の歯の下面と任意の傾斜角度にすることができるので、チップソーの切れ味がよく連続使用期間をおよそ２倍に延ばすことができる。また、刈払われた雑草の飛散範囲が従来のものよりも狭いので刈払われた雑草の片付けが容易である。   Since the blade surface of the tip 17 of the saw blade for a mowing brush cutter can be polished to an arbitrary inclination angle with the lower surface of the disc-like tooth of the tip saw, the tip saw has good sharpness and approximately doubles the continuous use period Can be extended. Moreover, since the range of the scattered weeds is narrower than that of the conventional one, it is easy to clean up the weeds.

本発明の草刈用刈払機で使用するチップソー５の研磨具の一例を図１に示すが、この図はチップソー誘導板３の下側からみた説明用のものてある。架台２に取付けたディスクグラインダー１とチップソー誘導板３とからなり、ディスクグラインダー１はその研磨用円板14が所定の高さで垂直方向に支持されていて、研磨円板14がディスクグラインダー１の胴体の移動により図中左右に移動できるようになっている。チップソー誘導板３は研磨用円板14に向かい前下がりに所定の傾斜角度（９０度からチップ17の天刃がチップソー５の円板状の歯の下面となす角度を引いた角度に等しい）をなすよう固定し、チップソー誘導板３にはその板面に縦長の溝４と、裏面に軸着されているチップソー誘導用のレバー６と、溝４の対向両縁に遊嵌しレバー６の作動により溝４に沿い自在に移動し得る台座とがあり、台座は横断面がＨ型をなし、両側に縦長の溝４と遊嵌する凹部を有し、台座の頂面にはチップソー５が回動可能なようにチップソー５の取付孔と嵌合する円環が固定されていて、円環の中心にボルトが植設されておりそれに円環より大径のキャップを螺合して緊締し、チップソー５が回動可能なようにチップソー５との間隙を小にしてある。そして、レバー６の開放時、台座が、傾斜している縦長の溝４の上限に位置するよう台座にはバネＡ８が付いている。なお、台座の頂面の円環にチップソー５の取付孔が嵌合して台座の頂面にチップソー５が載置されるのでチップソー５が回動可能でかつ台座とともに移動可能なように台座の頂面はチップソー誘導板３の最上面よりも上の位置になるようにしておかなければならない。また、チップソー５の円板状の歯面はチップソー誘導板３の側縁の板面と接近していたほうが後述の円柱突起11や円柱突起12との係合が効果的におこなわれるので、そのため縦長の溝４はチップソー誘導板３の凹面内に形成したほうが好適である。   FIG. 1 shows an example of a polishing tool for the tip saw 5 used in the brush cutter for mowing according to the present invention. This figure is for explanation as viewed from the lower side of the tip saw guide plate 3. The disc grinder 1 is attached to the gantry 2 and the tip saw guide plate 3. The disc grinder 1 has a polishing disc 14 supported in a vertical direction at a predetermined height, and the polishing disc 14 is the disc grinder 1. The body can be moved left and right in the figure by moving the body. The tip saw guide plate 3 faces the polishing disc 14 and has a predetermined tilt angle (equal to an angle obtained by subtracting the angle formed by the top blade of the tip 17 from the lower surface of the disc-like teeth of the tip saw 5 from 90 degrees). The chip saw guide plate 3 has a vertically long groove 4 on its plate surface, a tip saw guide lever 6 pivotally mounted on the back surface, and loosely fitted on both opposite edges of the groove 4 to operate the lever 6. There is a pedestal that can move freely along the groove 4, the pedestal has an H-shaped cross section, has recesses that loosely fit with the vertically long grooves 4 on both sides, and the tip saw 5 rotates on the top surface of the pedestal. A ring that fits into the mounting hole of the tip saw 5 is fixed so that it can move, and a bolt is planted in the center of the ring, and a cap having a larger diameter than the ring is screwed and tightened. The gap with the tip saw 5 is made small so that the tip saw 5 can rotate. Then, when the lever 6 is opened, the pedestal is provided with a spring A8 so that the pedestal is positioned at the upper limit of the inclined long groove 4. Since the mounting hole of the tip saw 5 is fitted to the ring on the top surface of the pedestal and the tip saw 5 is placed on the top surface of the pedestal, the tip saw 5 can be rotated and moved together with the pedestal. The top surface must be positioned above the top surface of the tip saw guide plate 3. Further, since the disk-like tooth surface of the tip saw 5 is closer to the plate surface of the side edge of the tip saw guide plate 3, the engagement with the cylindrical protrusion 11 and the cylindrical protrusion 12 described later is effectively performed. The longitudinal groove 4 is preferably formed in the concave surface of the tip saw guide plate 3.

また、レバー６の移動による台座の移動、すなわち帯状片７の移動の実施例として、「台座の裏面には縦断面コの字状の帯状片７が固定されていて、帯状片７による環状内にレバー６が挿通されており、レバー６の移動により台座も移動するようにしてある。」レバー６には手元付近で交差し、先端付近に円柱突起11がある、バネＢ10付きの補助レバー９があり、また、レバー６には補助レバー９のバネＢ10による開放角度を制限する突起15（ストッパー）があり、また、チップソー誘導板３の裏面に軸着している支持片16の先端にある円柱突起12がチップソー誘導板３の側縁の所定位置に当接し、支持片16にはバネ13の作動によりチップソー５が時計反対方向に回動できるように付勢してあり、円柱突起12がチップソーの歯の彎曲18内に嵌まっている状態にしてある。   Further, as an example of the movement of the pedestal by the movement of the lever 6, that is, the movement of the belt-like piece 7, “the belt-like piece 7 having a U-shaped longitudinal section is fixed to the back surface of the pedestal, The lever 6 is inserted into the pedestal, and the pedestal is also moved by the movement of the lever 6. ”The auxiliary lever 9 with spring B10 intersects the lever 6 near the hand and has a cylindrical protrusion 11 near the tip. Further, the lever 6 has a protrusion 15 (stopper) for limiting the opening angle of the auxiliary lever 9 by the spring B10, and is located at the tip of the support piece 16 that is pivotally attached to the back surface of the tip saw guide plate 3. The cylindrical projection 12 abuts on a predetermined position on the side edge of the tip saw guide plate 3, and the support piece 16 is urged so that the tip saw 5 can be rotated in the counterclockwise direction by the action of the spring 13. Fits into the tip saw tooth curve 18 Are you in that state.

この状態からレバー６を研磨用円板14方向に押出してチップソー５のチップ17の天刃を作動中のディスクグラインダー１の研磨用円板14に当接して研磨するのであるが、チップ17の天刃を的確に研磨用円板14に当接させるためには、あらかじめディスクグラインダー１の胴体を図中左右に移動して研磨円板14にチップ17の天刃が当接するように調節しておく必要がある。   From this state, the lever 6 is pushed in the direction of the polishing disc 14 and the top blade of the tip 17 of the tip saw 5 is brought into contact with the polishing disc 14 of the disk grinder 1 in operation to polish. In order to bring the blade into contact with the polishing disc 14 accurately, the body of the disc grinder 1 is moved to the left and right in the drawing in advance so that the top blade of the chip 17 contacts the polishing disc 14 in advance. There is a need.

以上のごときチップソーの研磨機を用いて、補助レバー９を引き寄せたままレバー６を時計反対方向に若干回転して補助レバー９の円柱突起11をチップソー５の手近にある歯の彎曲18内にが嵌め、補助レバー９を引き寄せたままレバー６をさらに時計反対方向に回転して、円柱突起12を嵌まっている歯の湾曲18内から隣接する時計方向の歯の彎曲18内に移動して嵌め、補助レバー９を放して補助レバー９の円柱突起11を歯の湾曲18内から外し、レバー６のみを研磨用円板14方向に押出してチップソー５のチップ17の天刃を作動中のディスクグラインダー１の研磨用円板14に当接して研磨時間を決め、ついでレバー６を元の位置に戻し、以上の研磨を繰り返してチップソー５を研磨する。       Using the tip saw polishing machine as described above, the lever 6 is slightly rotated in the counterclockwise direction while the auxiliary lever 9 is attracted, and the cylindrical protrusion 11 of the auxiliary lever 9 is moved into the curvature 18 of the tooth near the tipsaw 5. The lever 6 is further rotated in the counterclockwise direction while the auxiliary lever 9 is attracted, and the cylindrical protrusion 12 is moved from the inside of the tooth curve 18 into which the cylindrical protrusion 12 is fitted into the adjacent clockwise tooth curve 18. Then, the auxiliary lever 9 is released to remove the cylindrical protrusion 11 of the auxiliary lever 9 from the inside of the tooth curve 18, and only the lever 6 is pushed in the direction of the polishing disk 14 to operate the top blade of the tip 17 of the tip saw 5. The polishing time is determined by abutting against the polishing disk 14 of 1 and then the lever 6 is returned to the original position, and the above-described polishing is repeated to polish the tip saw 5.

ディスクグラインダー１は市販のものを購入して使用する。図中、説明のためディスクグラインダー１の研磨用円板14の安全カバーの図を省略してある。チップソー誘導板３を所定角度傾斜してチップ17の天刃の傾斜に合わせるため、傾斜角度は案内板をチップソー誘導板３の側面に取付けておいて好適な２０度にしてある。レバー６をバネＡ８の引く力に逆らいディスクグラインダー１の研磨用円板14方向に下げてチップの刃面17をディスクグラインダー１の研磨用円板14に当接して研磨する際は、若干の手加減を要する。すなわち、バネＡ８をレバー６の押圧緩衝用のバネとするのである。また、研磨時間は研磨の程度を確認しながら一刃に要する時間を調子をとりながら決めるようにする。   The disc grinder 1 is purchased from a commercially available one. In the drawing, the illustration of the safety cover of the polishing disc 14 of the disc grinder 1 is omitted for the sake of explanation. In order to incline the tip saw guide plate 3 by a predetermined angle to match the tilt of the top blade of the tip 17, the tilt angle is set to a suitable 20 degrees by attaching the guide plate to the side surface of the tip saw guide plate 3. When the lever 6 is lowered in the direction of the disc 14 for polishing of the disc grinder 1 against the pulling force of the spring A8 and the tip blade surface 17 is brought into contact with the disc 14 for polishing of the disc grinder 1 for polishing, it is slightly adjusted. Cost. That is, the spring A8 is used as a spring for pressing the lever 6. The polishing time is determined while adjusting the time required for one blade while checking the degree of polishing.
