A lifting magazine having a rail is guided, and a guide rail is installed between the roving frame installation position of each floor or the spinning frame installation position and the standby rail installation position, the end of which is the end of the storage rail of the lifting magazine whose end is at the standby rail position. Since the bobbin carriage with hanging thread bobbins or empty bobbins can be stored in the lifting magazine in its suspended state and easily transported to each floor, the roving bobbin can be transported to a different floor. The yarn quality can be improved by preventing damage to the rovings when the yarn is loaded, and the bobbin can be transported mechanically, reducing the labor involved in transporting and loading and unloading the bobbin. can. In addition, standby rails are installed on both sides of the lifting locus of the lifting body on each floor, and a lifting magazine with a storage rail is guided by a part of the lifting rail and the waiting rail, and the lifting magazine is moved from the lifting rail to one of the waiting rails. Since the other elevating magazine can be moved to the elevating rail at the same time or immediately after the elevating body is moved, the carrying capacity of the elevating magazine by the elevating body can be greatly increased, and the number of elevating bodies installed can be reduced, reducing equipment costs. There is an effect that can be done.
