Title
(EN) INJECTION DEVICE AND CONTROL METHOD
(FR) DISPOSITIF D'INJECTION ET MÉTHODE DE CONTRÔLE
(JA) 射出装置および制御方法
Abstract
(EN) In an injection device (10) according to an embodiment, each of a plurality of outer peripheral protrusions (50) of a screw (12) is formed with an outer peripheral protrusion inclined surface (50S), and each of a plurality of inner peripheral protrusions (60) of a through-hole (14H) of a bush (14) is formed with an inner peripheral protrusion inclined surface (60S). The injection device (10) advances the bush (14) until a linear-motion torque exceeds a linear-motion torque threshold, and, if a rotation torque exceeds a rotation torque threshold before the linear-motion torque exceeds the linear-motion torque threshold, ends control processing when the linear-motion torque exceeds the linear-motion torque threshold.
(FR) Dans un dispositif d'injection (10) selon un mode de réalisation, chacune d'une pluralité de saillies périphériques externes (50) d'une vis (12) est formée avec une surface inclinée de saillie périphérique externe (50S), et chacune d'une pluralité de saillies périphériques internes (60) d'un trou traversant (14H) d'une douille (14) est formée avec une surface inclinée de saillie périphérique interne (60S). Le dispositif d'injection (10) fait avancer la douille (14) jusqu'à ce qu'un couple de mouvement linéaire dépasse un seuil de couple de mouvement linéaire, et, si un couple de rotation dépasse un seuil de couple de rotation avant que le couple de mouvement linéaire dépasse le seuil de couple de mouvement linéaire, termine le traitement de contrôle lorsque le couple de mouvement linéaire dépasse le seuil de couple de mouvement linéaire.
(JA) 一実施形態による射出装置(10)では、スクリュー(12)の複数の外周突起(50)の各々に外周突起斜面(50S)が形成され、ブッシュ(14)の貫通孔(14H)の複数の内周突起(60)の各々に内周突起斜面(60S)が形成される。射出装置(10)は、直動トルクが直動トルク閾値を超えるまでブッシュ(14)を前進させ、直動トルクが直動トルク閾値を超える前に回転トルクが回転トルク閾値を超えた場合には、直動トルクが直動トルク閾値を超えたときを契機として制御処理を終了する。
