Title (EN) BAND SAW
(FR) SCIE À RUBAN
(JA) バンドソー
Abstract:
(EN) Provided is a band saw in which a plastic housing is used in order to reduce the weight of a device, and in which the likelihood of a blade dislodging from a guide roller is reduced. A first guide roller mechanism 30 and a second guide roller mechanism 40 have a pair of cylindrical guide rollers that rotate while being in contact, respectively, with the outer peripheral side and the inner peripheral side of the blade 20. The tip sides of the guide rollers 31, 41 and the guide rollers corresponding to the guide rollers 31, 41 are inclined with respect to the direction in which the blade runs. As a result, a force acts on the blade in the direction opposite that in which the blade is dislodged, making it possible to stabilize the position in which the blade is running.
(FR) L'invention concerne une scie à ruban dans laquelle un boîtier en matière plastique est utilisé afin de réduire le poids d'un dispositif, et dans laquelle la probabilité qu'une lame se détachera d'un rouleau de guidage est réduite. Un premier mécanisme de rouleau de guidage (30) et un second mécanisme de rouleau de guidage (40) ont une paire de rouleaux de guidage cylindriques qui tournent tout en étant en contact, respectivement, avec le côté périphérique externe et le côté périphérique interne de la lame (20). Les côtés de pointe des rouleaux de guidage (31, 41) et les rouleaux de guidage correspondant aux rouleaux de guidage (31, 41) sont inclinés par rapport à la direction dans laquelle se déplace la lame. Par conséquent, une force agit sur la lame dans la direction opposée à celle dans laquelle la lame est délogée, rendant ainsi possible de stabiliser la position dans laquelle la lame se déplace.
(JA) 樹脂製のハウジングを用いて装置の軽量化を図ると共に、帯鋸がガイドローラからずれにくくしたバンドソーを提供する。第一ガイドローラ機構30及び第二ガイドローラ機構40は、帯鋸20の外周側と内周側にそれぞれ接しながら回転する円筒状の一組のガイドローラを有し、ガイドローラ31、41とそれに対応するガイドローラの先端側を、帯鋸の走行方向に対して傾斜させるようにした。この結果、帯鋸に対して外れる方向と反対側への力がかかるようになるので、帯鋸の走行位置を安定させることができる。
