【0006】
【発明が解決しようとする課題】
前者のブラシ駆動専用のモータを設ける方式は部品点数が多くなりコストが高くなるという問題がある。後者の場合は回転ブラシの回転方向が鋸刃走行方向に対して垂直でないためが低下する。また、切り粉が回転力を伝達するギヤに挟まると駆動部部が破損したり回転が停止したりする恐れがある。また、ワイヤーブラシが摩耗したときに、鋸刃とワイヤーブラシとの重なり量が調節できない。
【0007】
本発明は上述の如き問題を解決するためになされたものであり、本発明の目的は、回転ブラシの駆動力を鋸刃駆動ホイールから得る帯鋸盤の切り粉除去装置において、切り粉除去能率がよく、かつ切り粉による破損の恐れのない回転ブラシ駆動部を有すると共に、鋸刃とワイヤーブラシとの重なり量の調節が容易な帯鋸盤の切り粉除去装置を提供することである。
【0008】
【課題を解決するための手段】
上述の課題を解決する手段として請求項1に記載の帯鋸盤の切り粉除去装置は、駆動ホイールと従動ホイールの間に掛回した帯鋸刃の走行途上の歯部に接触して前記歯部に付着する切り粉を除去するワイヤブラシを有し、前記駆動ホイールの回転力を前記ワイヤブラシに伝達する回転力伝達手段を備えた帯鋸盤の切り粉除去装置において、前記回転力伝達手段は軸受け箱に回転自在に軸支した駆動軸に前記駆動ホイールの外周に接触自在の駆動輪を設けると共に、前記軸受け箱に前記駆動軸にほぼ直交するブラシ回転軸を備えたワイヤブラシを回転自在に設け、前記駆動軸に駆動傘歯車を設けると共に、該駆動傘歯車に噛合する従動傘歯車を前記ブラシ回転軸に設け、前記軸受け箱を前記駆動軸を軸に回動可能に軸支する軸受け箱支持体を設けると共に、該軸受け箱支持体を前記駆動ホイールの回転軸と平行に設けたヒンジ軸を軸にして回動可能に設け、該ヒンジ軸を軸にして前記駆動輪を前記駆動ホイールに押圧付勢するスプリングを設け、前記ワイヤブラシ軸を前記駆動輪の駆動軸を軸にして回動させることにより、ワイヤブラシと帯鋸刃の重なりを調節可能に設けたことを要旨とするものである。
【0009】
請求項2に記載の帯鋸盤の切り粉除去装置は、請求項1に記載の帯鋸盤の切り粉除去装置において、前記軸受け箱に該軸受け箱の回動位置を固定自在のクランプを設けたことを要旨とするものである。
【0010】
【発明の実施の形態】
以下、本発明の実施の形態を図面によって説明する。
【0011】
図1は本発明に係る帯鋸盤の切り粉除去装置1を帯鋸盤のひとつである吊りピース切断装置100に適用した場合の要部の説明図である。
【0012】
吊りピース切断装置100とは、大型の構造物にワイヤーまたはフックを掛けるために溶接などにより一時的に設けた突起物(吊りピース)を切断するのに適した帯鋸盤である。吊りピース切断装置100に関しては、後にその概要を説明する。なお、本発明の帯鋸盤の切り粉除去装置は吊りピース切断装置への適用に限定されるものではなく一般的な横型帯鋸盤または縦型帯鋸盤に適用することができる。
【0013】
図1〜図6を参照するに、前記吊りピース切断装置100における駆動ホイール129上部近傍を水平走行する帯鋸刃133の近傍の鋸刃ハウジング123に切り粉除去装置1の取付け基板9が複数のねじ11により取付けてある。
【0014】
取付け基板9には、前記駆動ホイール129の回転軸(図示省略)と平行にヒンジ軸13が設けてあり、このヒンジ軸13に断面形状が下向きにコの字の軸受け箱支持体15が回動可能に軸支してある。
【0015】
また、軸端部に前記駆動ホイール129の外周に接触自在の駆動輪17を備えた駆動軸19をベアリング20を介して回転自在に軸支する軸受け箱21を設け、この軸受け箱21に前記駆動軸19にほぼ直交するブラシ回転軸23を備えたワイヤブラシ25をベアリング22を介して回転自在に設け、前記軸受け箱内部に軸支された前記駆動軸19に駆動傘歯車27を設けると共に、前記軸受け箱内部に軸支された前記ブラシ回転軸23の端部に前記駆動傘歯車27に噛合する従動傘歯車29を設け、軸受け箱外部に延伸した前記ブラシ回転軸23の他端部に前記ワイヤーブラシ25を着脱可能に取り付けてある。
【0016】
また、前記軸受け箱21は前記軸受け箱支持体15に前記駆動軸19を軸として回動可能に軸支してある。より詳細には、前記駆動輪17側の端部から延伸した軸部を軸受け箱支持体15に取り付けた軸受け31に回動自在に軸支すると共に、前記駆動軸19の軸心の延長線上にある軸受け箱21の端部に螺合するクランプねじ33に回動自在に嵌合してある。なお、クランプねじ33には操作ハンドル33aが設けてある。また軸受け箱21と軸受け箱支持体15の間には、スペーサー34が挿入してあるが、スペーサー34を軸受け箱支持体15に一体的に設けても構わない。
【0017】
図5、図6、図8によく示されるように、前記軸受け箱支持体15の上面と前記取付け基板9からほぼ水平に張りだしたプリング取付け座9aとの間には、前記ヒンジ軸13を軸にして時計回りに(図6において)前記軸受け箱支持体15を押圧付勢するスプリング35が設けてある。したがって、軸受け箱21に駆動軸19を軸として回動可能に軸支された前記駆動輪17は、前記駆動ホイール129に常時適宜な圧力で押圧されることになる。
【0018】
上記構成におけるワイヤブラシの調整と動作について説明する。
【0019】
帯鋸盤を作動させると、前記駆動輪17は駆動ホイール129によって回転駆動され、駆動輪17の駆動軸19に設けた駆動傘歯車27を介してブラシ回転軸23の従動傘歯車29が回転駆動されることになる。したがって、ブラシ回転軸23の端部に装着したワイヤブラシ25が回転する。
【0020】
図4、図8に示す如く、ブラシ回転軸23は駆動軸19と直交しているので、ワイヤーブラシ25の回転方向は走行する帯鋸刃133に対して直交し、鋸刃の歯先から離れる方向に回転することになる。
【0021】
ワイヤーブラシ25と帯鋸刃133との重なり量は、前記駆動輪17の駆動軸19を軸にして前記ワイヤブラシ軸23を回動させることにより、ワイヤブラシ25と帯鋸刃133との重なりを調節する。
【0022】
なお、ワイヤブラシ25の位置を調節するには、操作ハンドル33aを回してクランプねじ33を緩めて、ワイヤブラシ25を回動させて帯鋸刃133との重なりを調節したらクランプねじ33を締めて固定する。
【0023】
図10、図11に示す如く、ワイヤーブラシ25が摩耗して直径が小さくなった場合には、ブラシ回転軸23を調節してワイヤーブラシ25と鋸刃との重なり量を適宜な量に調節することができる。
【0024】
ワイヤーブラシ25の直径が調整範囲を越えて小さくなった場合には、ブラシ回転軸23の先端の蝶ナット37を緩めれば、容易に新品のワイヤーブラシ25に交換することができる(図11参照)。
【0025】
また、ワイヤーブラシ25と軸受け箱21の間には、鋸刃5が通過可能な切欠き部を備えた遮蔽板39が軸受け箱21に取付けてある。この遮蔽板39によりワイヤーブラシ側から切り粉が軸受け箱21や駆動輪17の方へ飛散するのを防止すると共に、前記切り粉除去装置1の取付け基板9には、駆動ホイール129と駆動輪17との間へ切り粉が巻き込むのを防止するスクレーパ41が取付けてある。
【0026】
上述のようにして、ワイヤーブラシ25と帯鋸刃133とが適宜な重なり量となるように調節が完了して切断開始準備が完了する。その結果、帯鋸刃の歯部に付着した切り粉の除去能率が向上する。なお、除去された切り粉はシューター40を介して下方の切り粉受け(図示省略)に落下するようになっている。
【0027】
以下に前述の吊りピース切断装置100の概要を説明する。
【0028】
図12〜図14は、本発明に係る帯鋸盤の切り粉除去装置を装着した吊りピース切断装置100の全体構成を説明する図である。
【0029】
図12、図13に示す如く、吊りピース切断装置100は、帯鋸刃駆動ユニット103を前後方向(図12では紙面に直交する方向、図14では左右方向)へ移動自在に支持する本体フレーム105を備えている。
【0030】
この本体フレーム105は、前後方向に平行して延伸する左右一対のベースフレーム107(a,b)を有し、この左右ベースフレーム107(a,b)の前端部と後端部のそれぞれに左右一対の支柱109(a,b)を立設し、この左右一対の支柱間を水平な梁部材111(f,r)で一体的に結合した構成となっている。
【0031】
前記支柱109(a,b)は梁部材111(f,r)よりさらに上へ延伸して設けてあり、その上端部に前記支柱109aと9bの間を水平に連結する握り棒113(f,r)が前記梁部材111(f,r)と平行に設けてある。
【0032】
前記本体フレーム105の左側のベースフレーム107aの外側面には、ベースフレーム107aの前端部と後端部に渡る直線運動軸受け用のガイドレール115が取り付けてあり、前記右側のベースフレーム107bの外側端部には、上下一対のラジアル軸受け(図示省略)で挟持するためのベアリングガイド部(図示省略)が設けてある。
【0033】
一方、前記帯鋸刃駆動ユニット103は、切断加工対象である構造物117上面に一体的に設けた突起物(吊りピース)119が通過可能な開口部121を有する鋸刃ハウジング23を備えており、この鋸刃ハウジング123には減速機(図示省略)を介して駆動モータ127により回転駆動される駆動ホイール129と従動ホイール131とが前記開口部121を挟んで設けてある。駆動ホイール129と従動ホイール131には帯鋸刃133が巻き付けてある。
【0034】
上述の帯鋸刃駆動ユニット103は、前記ガイドレール115とベアリングガイド部とに案内されて、ベースフレーム107(a,b)上を前後方向へ移動自在に設けてあり、また前記鋸刃ハウジング123内には、前記ベースフレーム107(a,b)上に水平に張られた一対のチェーン137(a,b)に係合するスプロケット(図示省略)を備えた駆動モータ145が設けてある。
【0035】
上記構成において、駆動モータ145を適宜に駆動すれば、帯鋸刃駆動ユニット103が切断加工対象である突起物(吊りピース)119に対して水平に接近または後退できるように設けてある。
【0036】
突起物(吊りピース)119を切断するときには、突起物(吊りピース)119を本体フレーム105に設けたクランプ装置151で固定する。なお、クランプ装置151は棒状ストッパー161と、棒状ストッパー161に摺動自在に嵌合したクランプアーム163と、左セットプレート153aに対して垂直に進退自在に螺合した締め付けねじ167などから構成されている。また、図14に示す如く吊りピース切断装置100には、固定キャスター175とリフト機構付きキャスター177およびスタンド181がついているので、切断位置へ容易に移動すると共に固定できるようになっている。
【0037】
【発明の効果】
請求項1または請求項2の発明によれば、回転ブラシの駆動力を鋸刃駆動ホイールから得る帯鋸盤の切り粉除去装置において、帯鋸刃に対してワイヤブラシが垂直に当たるので切り粉除去能率が向上する。また、ワイヤブラシ回転軸を駆動輪の軸を中心にして回動させることにより、ワイヤブラシと帯鋸刃の重なり量が容易に調節できると共に、ワイヤブラシの交換も容易となる。
【0038】
また、鋸刃駆動ホイールと駆動輪の間に切り粉が入っても、駆動輪が鋸刃駆動ホイールの直径方向へ逃げるので、装置が破損したり駆動輪が停止したりすることがない。
