湿式ウレタン舗装表面切削機に使用されているカッターユニットは、ウレタン切削粉を含んだ汚水が排水溝や河川へ流出する。 A cutter unit used in a wet urethane pavement surface cutting machine discharges sewage containing urethane cutting powder into drains and rivers.

乾式ウレタン舗装表面切削機に使用されているカッターユニットは雨天の場合切削粉が回収口などに溶着するため作業中止となる。 The cutter unit used in the dry urethane pavement surface cutting machine stops working when it rains because the cutting dust adheres to the collection port.

機械本体の幅に比べカッター幅が狭い為、現場端部隅々までの表面切削加工が出来ない。 Since the width of the cutter is narrower than the width of the machine body, it is not possible to cut the surface to every corner of the site.

図１から図６を参照しながら、本発明の実施形態の詳細を説明する。なお、以下の実施形態は、本発明の一例であって、本発明、その適用物、あるいはその用途の範囲を制限することを意図するものではない。 Details of embodiments of the present invention will now be described with reference to FIGS. The following embodiments are examples of the present invention, and are not intended to limit the scope of the present invention, its applications, or its uses.

図６に示すウレタン舗装表面切削機は全天候型の陸上競技用トラック、テニスコートなどの表面補修工事に主に使用するもので電動機またはエンジンで図１、２に示すメインカッターＦｒ１，Ｒｒ２を有しているウレタン舗装表面切削機用カッターユニットを駆動し舗装表面を切削する。切削粉はウレタン舗装表面切削機が有する切削粉回収用ブロアーで吸引し切削粉回収袋に回収する。 The urethane pavement surface cutting machine shown in FIG. 6 is mainly used for surface repair work on all-weather tracks, tennis courts, etc., and has main cutters Fr1 and Rr2 shown in FIGS. The cutter unit for the urethane pavement surface cutting machine is driven to cut the pavement surface. The cutting powder is sucked by a cutting powder collecting blower of the urethane pavement surface cutting machine and collected in a cutting powder collecting bag.

図１、図２に示すメインカッターＦｒ１、Ｒｒ２は舗装表面を切削するもので、２軸の外周に等角度で切削用チップ５を取付けた回転ディスク部１ａ、２ａを所定間隔空けて複数列設け、切削熱の放熱と空冷のため空冷流路部１ｄ、２ｄは各回転ディスクの間隙部に設ける。図１に示すように未切削部が残らないようにメインカッターＦｒ１が有する回転ディスク部１ａ・空冷流路部１ｄとメインカッターＲｒ２が有する回転ディスク部２ａ・空冷流路部２ｄは千鳥に配置する。 The main cutters Fr1 and Rr2 shown in FIGS. 1 and 2 are for cutting the pavement surface, and are provided with a plurality of rows of rotating disk portions 1a and 2a having cutting tips 5 mounted at equal angles on the outer periphery of the two shafts at predetermined intervals. , Air-cooling passages 1d and 2d are provided in the gaps between the rotating discs for the purpose of radiating cutting heat and air-cooling. As shown in FIG. 1, the rotary disc portion 1a and air-cooling passage portion 1d of the main cutter Fr1 and the rotary disc portion 2a and air-cooling passage portion 2d of the main cutter Rr2 are arranged in a staggered manner so that no uncut portion remains. .

回転転ディスク部１ａ、１ｂと切削用チップ５の冷却はメインカッター自体の回転と機械本体に設ける切削粉回収用ブロアーによる空気が所定間隔を空けて複数列設けた空冷流路部を流れて空冷する。 The rotating discs 1a and 1b and the cutting tip 5 are cooled by the rotation of the main cutter itself and the blower for collecting cutting powder provided in the machine body, in which air flows through multiple rows of air cooling passages provided at predetermined intervals. do.

メインカッターＦｒ１、Ｒｒ２の例えば回転ディスク部１ａ、２ａの幅１０ｍｍ、空冷流路部１ｄ、２ｄの幅１０ｍｍとすると回転ディスク部の間隔は２０ｍｍとなり、切削用チップ５の幅１２．７ｍｍとすると表面切削は７．３ｍｍ未切削となる。 For example, if the width of the rotating disk portions 1a and 2a of the main cutters Fr1 and Rr2 is 10 mm, and the width of the air cooling passage portions 1d and 2d is 10 mm, the interval between the rotating disk portions is 20 mm. Cutting becomes 7.3 mm uncut.

メインカッターＦｒ１、Ｒｒ２の未切削部を無くする為、例えば２軸の回転ディスク部１ａ、２ａと空冷流路部１ｄ、２ｄを１０ｍｍずらし千鳥に配置しメインカッターＦｒ１で１２．７ｍｍ、メインカッターＲｒ２で未切削部の７．３ｍｍ切削する。（図４参照） In order to eliminate the uncut portions of the main cutters Fr1 and Rr2, for example, the two-axis rotating disk portions 1a and 2a and the air-cooled passage portions 1d and 2d are arranged in a staggered manner with a 10 mm shift. Cut 7.3 mm of the uncut portion with . (See Figure 4)

メインカッターＦｒ１、Ｒｒ２は図１に示すように両端を軸受６で支え、回転方向は切削粉を２軸の中間の切削粉回収口に効率よく集めるためメインカッター駆動軸側側面図２から見てメインカッターＦｒ１は反時計回転、メインカッターＲｒ２は時計回転とする。（図４参照） Both ends of the main cutters Fr1 and Rr2 are supported by bearings 6 as shown in FIG. The main cutter Fr1 rotates counterclockwise, and the main cutter Rr2 rotates clockwise. (See Figure 4)

メインカッターの駆動は例えば電動機またはエンジンを駆動源としメインカッターＦｒ１、Ｒｒ２の駆動軸部１ｂ、２ｂに歯付プーリを取付け、両面歯付ベルトのＳ字掛けで反時計回転、時計回転にする。（図６参照） The main cutters are driven by, for example, an electric motor or an engine, and toothed pulleys are attached to the drive shafts 1b and 2b of the main cutters Fr1 and Rr2, and the double-sided toothed belts are S-shaped to rotate counterclockwise and clockwise. (See Figure 6)

着脱式サイドカッター３，４は現場端部隅々まで表面切削加工を可能にするためのもので、図１に示すように回転ディスク部３ａ、４ａおよび空冷流路部３ｂ、４ｂはメインカッター１，２に準じた構想で、メインカッターＦｒ１、Ｒｒ２の着脱式サイドカッター取付け軸部１ｃ、２ｃに組付ける。 The detachable side cutters 3 and 4 are for enabling surface cutting to every corner of the site, and as shown in FIG. , 2, and assembled to the detachable side cutter mounting shafts 1c and 2c of the main cutters Fr1 and Rr2.

着脱式サイドカッターの回転ディスク部３ａ、４ａはメインカッターの回転ディスク１ａ、２ａの外径より数ミリ大きく形成されており、現場端部隅々までの表面切削加工時にはメインカッターは空転している。回転方向はメインカッターと同じで切削粉を回収口に集める。現場端部隅々まで表面切削加工作業の無い時は取外して保管する。（図５参照） The rotating discs 3a and 4a of the detachable side cutter are formed several millimeters larger than the outer diameter of the rotating discs 1a and 2a of the main cutter, and the main cutter is idling during surface cutting to every corner of the edge of the site. . The direction of rotation is the same as that of the main cutter, and the cutting dust is collected in the collection port. When there is no surface cutting work to every corner of the site, remove it and store it. (See Fig. 5)

切削用チップ５はウレタン舗装表面切削の要で、適切なすくい角をとり、例えば靭性の高い超硬にＣＶＤ法（化学蒸着法）によって薄膜をコーティングし高硬度・耐摩耗性・低切削抵抗などに優れた切削用チップを使用する。 The cutting tip 5 is the key to cutting the urethane pavement surface, and has an appropriate rake angle. Use cutting inserts with excellent cutting performance.

切削用チップ５は図２、図３に示すよう４コーナー使用可能な切削用チップを切削チップ取付けネジ５ａで取付け切削チップ５のコーナーが損耗した場合順次切替え、長期に安定して使用が出来るものとしコーナー全て損耗した場合切削用チップ５を交換する。 As shown in Figs. 2 and 3, the cutting tip 5 is a cutting tip that can be used at four corners and is attached with a cutting tip mounting screw 5a. When the corners of the cutting tip 5 are worn, they can be switched sequentially and can be used stably for a long period of time. If all the corners are worn, the cutting tip 5 is replaced.

クロスフローフアン用翼１ｅ、２ｅ、３ｃ、４ｃは図１、２、３に示すように例えばフラットバーを湾曲状にプレス成形、またはパイプを等角度で分割した形状で幅は数十ミリ、長さはメインカッター１、２の全幅、着脱式サイドカッター３、４の全幅とする。 The blades 1e, 2e, 3c, and 4c for the cross-flow fan are, as shown in FIGS. The width is the full width of the main cutters 1 and 2 and the full width of the detachable side cutters 3 and 4.

クロスフローフアン用翼は図２，３に示すように回転ディスク部１ａ、２ａ，３ａ、４ａの切削用チップ５の取り付面の背面に空気をすくうように頂部を回転ディスク部の回転方向と反対側に張出させ、クロスフローフアン用翼がウレタン舗装表面に当たらないように外周を切削用チップのより数ミリ内寄りに取付ける。 As shown in FIGS. 2 and 3, the blades for the cross-flow fan have their tops oriented in the direction of rotation of the rotating discs 1a, 2a, 3a, and 4a so as to scoop the air behind the mounting surfaces of the cutting tips 5 of the rotating discs 1a, 2a, 3a, and 4a. Extend it to the opposite side, and attach the outer circumference a few millimeters inward of the cutting tip so that the wings for the cross flow fan do not hit the urethane pavement surface.

カッターユニットを駆動するとクロスフローフアン用翼により空気は多列の空冷流路部をほぼ均等に流れ、回転ディスク部と切削用チップの強制空冷とともに切削粉の回収を促進し、切削加工作業前後の清掃・集塵など活用が出来る。 When the cutter unit is driven, air flows almost evenly through the multi-row air cooling channels due to the blades for the cross-flow fan, which promotes the forced air cooling of the rotating disk and cutting chips and the collection of cutting powder. It can be used for cleaning and dust collection.
