Title (EN) AUTOMATIC PRODUCTION APPARATUS AND AUTOMATIC PRODUCTION METHOD
(FR) APPAREIL DE PRODUCTION DE AUTOMATIQUE ET PROCÉDÉ DE PRODUCTION AUTOMATIQUE
(JA) 自動生産設備および自動生産方法
Abstract:
(EN) The present invention ensures, without increased complexity of the structure of an electric driver, that when a screw is picked up, a bit is inserted into the screw head. The electric driver 140 of an automatic production apparatus comprises a bit 20, a main body 10 and a cover 40. The bit 20 engages with the engaging slot of a screw 300. The main body 10 rotates the bit. The cover 40 is cylindrical and covers the bit 20. The inner diameter of the cover 40 is the same as the diameter of the screw head of a screw 300 that is to be tightened. The bit 20 is provided so that the tip of the bit 20 protrudes from the cover 40 when the bottom of the engaging slot formed in the screw head is closer to the top of the screw head than the terminal edge of a chamfer formed on the screw head, and so that the bit 20 is stowed in the cover 40 when the terminal edge of the chamber formed on the screw head is closer to the top of the screw head than the bottom of the engaging slot formed in the screw head.
(FR) La présente invention assure, sans augmentation de la complexité de la structure d'un tournevis électrique, que lorsqu'une vis est saisie, un foret est introduit dans la tête de vis. Le tournevis électrique 140 d'un appareil de production automatique comprend un foret 20, un corps principal 10 et un cache 40. Le foret 20 entre en prise avec la fente d'entrée en prise d'une vis 300. Le corps principal 10 fait tourner le foret. Le cache 40 est cylindrique et recouvre le foret 20. Le diamètre intérieur du cache 40 est identique au diamètre de la tête de vis d'une vis 300 qui doit être serrée. Le foret 20 est prévu de telle sorte que la pointe du foret 20 dépasse du cache 40 lorsque le fond de la fente d'entrée en prise formée dans la tête de vis est plus proche du sommet de la tête de vis que le bord terminal d'une chambre formée sur la tête de vis, et de telle sorte que le foret 20 est rangé dans le cache 40 lorsque le bord terminal de la chambre formée sur la tête de vis est plus proche du sommet de la tête de vis que le fond de la fente d'entrée en prise formée dans la tête de vis.
(JA) 電動ドライバの構造を複雑化せずにねじをピックアップした際にねじ頭にビットが挿入されることを担保する。自動生産設備が有する電動ドライバ140は、ビット部20、本体部10、およびカバー部40を有する。ビット部20は。ねじ300の嵌合部に嵌合する。本体部10は、ビットを回転させる。カバー部40は、円筒状からなり、ビット部20を覆う。カバー部40の内径は、締め付けるねじ300のねじ頭の直径と同じである。ビット部20は、ねじ頭に形成される嵌合部の底面がねじ頭に形成される面取りの終端部よりもねじ頭の頂部に近い場合、ビット部20の先端部がカバー部40から突出するように設けられ、ねじ頭に形成される面取りの終端部がねじ頭に形成される嵌合部の底面よりもねじ頭の頂部に近い場合、ビット部20がカバー部40に収納されるように設けられる。
