Title (EN) WORKPIECE CONVEYANCE SYSTEM AND MACHINE TOOL SYSTEM
(FR) SYSTÈME DE TRANSPORT DE PIÈCE À USINER ET SYSTÈME DE MACHINE-OUTIL
(JA) ワーク搬送システム及び工作機械システム
Abstract:
(EN) [Problem] To improve workpiece machining efficiency even when there are multiple workpiece-holding parts by efficiently delivering workpieces to each workpiece-holding part and shortening the time necessary for workpiece conveyance. [Solution] A workpiece conveyance system 50 for delivering workpieces W to main shafts (workpiece-holding parts) 11, 12, 21 and 22, which hold and rotate a workpiece W to be machined, wherein the workpiece conveyance system comprises a main loader 52 provided with n+m (n being an integer ≥2 and m being an integer ≥1) main loader chucks 56 for delivering workpieces to and from each of n main shafts 11, 12, 21 and 22 or to and from n relay loaders 51 that are each disposed facing the n main shafts 11, 12, 21 and 22 and deliver workpieces W to and from the main shafts 11, 12, 21 and 22.
(FR) Le problème décrit par la présente invention est d'améliorer l'efficacité d'usinage de pièce à usiner même lorsqu'il y a de multiples parties de maintien de pièce à usiner en distribuant efficacement des pièces à usiner à chaque partie de maintien de pièce à usiner et en raccourcissant le temps nécessaire au transport de pièces à usiner. La solution selon l'invention porte sur un système de transport de pièces à usiner (50) permettant de distribuer des pièces à usiner (W) à des arbres principaux (pièces de maintien de pièce à usiner) (11, 12, 21 et 22), qui maintiennent et font tourner une pièce à usiner (W) en vue de son usinage, le système de transport de pièces à usiner comprenant un chargeur principal (52) pourvu de n+m (n étant un entier ≥ 2 et m étant un nombre entier ≥1) mandrins de chargeur principaux (56) pour distribuer des pièces à usiner vers et depuis chacun des n arbres principaux (11, 12, 21 et 22) ou vers et depuis n chargeurs de relais (51) qui sont chacun disposés en regard des n arbres principaux (11, 12, 21 et 22) et délivrer des pièces à usiner (W) vers et depuis les arbres principaux (11, 12, 21 et 22).
(JA) 【課題】ワーク保持部が複数ある場合においても各ワーク保持部に対してワークの受け渡しを効率よく行い、ワークの搬送に要する時間を短縮してワークの加工効率を向上させる。 【解決手段】ワーク搬送システム50は、加工対象のワークWを保持して回転する主軸(ワーク保持部)11、12、21、22に対してワークWを受け渡しするワーク搬送システムであって、n(n≧2の整数)個の主軸11、12、21、22のそれぞれに対して、又はn個の主軸11、12、21、22のそれぞれに対応して配置され、主軸11、12、21、22に対してワークWを受け渡しするn個の中継ローダ51に対してワークを受け渡すn+m(m≧1の整数)個の主ローダチャック56を備える主ローダ52と、を有する。
