Integrated device and method for transporting bobbins and tubes between a roving frame and a spinning frame of a spinning line

An integrated device (50) performs the picking of dirty tubes (12) from a secondary transport device (26) of a spinning frame (8) and bobbins (10) from a main transport device (22) of a roving frame (6), the cleaning of the dirty tubes (12) to obtain empty tubes (14), the exchange of the bobbins (10) with the empty tubes (14) and the release of the bobbins (10) to the secondary transport device (26) and of the empty tubes (14) to the main transport device (22). The working method of the spinning line avoids that, between the picking of the dirty tube (12) and the release of the related empty tube (14), said dirty (12) or empty (14) tube is further released. 种集成装置(50)，所述集成装置执行：从细纱机(8)的辅助传输装置(26)拾捡污管件(12)并从粗纱机(6)的主传输装置(22)拾捡筒管(10)，清洁污管件(12)以获得空管件(14)，将筒管(10)与空管件(14)进行交换，以及将筒管(10)释放至辅助传输装置(26)并将空管件(14)释放至主传输装置(22)。纺纱生产线工作方法避免了在拾捡污管件(12)与释放关联的空管件(14)之间进步释放污管件(12)或空管件(14)。
