INTEGRATED DEVICE AND METHOD FOR TRANSPORTING BOBBINS AND TUBES BETWEEN A ROVING FRAME AND A SPINNING FRAME OF A SPINNING LINE

摘要

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.
