After that, when the carriage element 24af at the rail element 35af position is sent to the second rail 34f position and the connecting piece 30f of the carriage element 24af is pushed down by the cam plate 84, the carriage element 24af is temporarily stopped from being fed. After that, after the transfer body 70f is moved by one pitch, the next carrage element 24af is sent to the position of the second rail 34f and brought into contact with the stopped carrage element 25f, and then both the carrage elements 24af are moved again. By this, the connecting piece 30f is disengaged from the cam plate 84 and pushed up by the spring 76, the connecting pin 77 is fitted into the connecting hole 78, and both the carrage elements 24af are connected. By repeating the above operation, all the carrage elements 2 of the bobbin carrage 24f.
4af are connected in series, and in this state, the bobbin carriage 24f is moved to the spinning machine installation position Bf. The above-described operation can be mechanized by a combination of well-known appropriate detecting means and moving means, but it may be performed by the operator's judgment and operation. The engagement and disengagement of the connecting pin 77 and the connecting hole 78 may be performed manually by an operator.

In the present application, the first, second, and third rails may be double-rowed and used for forward and backward respectively, so that the bobbin carriage can be continuously conveyed. Also, in the spinning machine position, instead of the spare rail, the creel rails are arranged in front of the creel and above the rear row bobbin hangers, respectively.The bobbin carriage is fed to the creel rails, and the bobbin hangers of the bobbin carage are moved to The bobbin hangers may be used as the bobbin hangers. In this case, the bobbin hangers of the bobbin carriage may be arranged in two rows, and the creel rail may be provided on one side of the spinning machine. Further, the elevating device may be configured by a crane or the like that directly elevates and lowers the third rail, and is not limited to the existing elevator.

As described above, according to the present invention, the bobbin hanger of the bobbin carriage guided by the first rail is made to hang the roving bobbin fried from the roving machine, and the bobbin carage is moved to the third rail. After raising and lowering the elevating device to the level of the spinning machine installation, the bobbin carriage is then guided to the second rail and moved to the spinning machine installation position, and the roving bobbin fried from the roving machine is suspended. Since the roving bobbin is transported to the spinning machine installation position by the above, damage to the roving of the roving bobbin can be reduced and the yarn quality can be improved even when the roving bobbin is transported to different layers. It is possible to mechanically convey the roving bobbin that has been suspended to the position of the spinning machine, reduce the labor for feeding and unloading the roving bobbin, and save labor by automation. In addition, the carriage element of the bobbin carriage is bent or separated at the connecting portion to change the alignment from the serial state to the parallel state, and the bobbin carriage in that state is guided to the third rail and supported in the lifting device. Therefore, it is possible to easily and quickly support a long bobbin carrage on a short lifting device, which can shorten the transportation time and use the existing elevator to lift the bobbin carrage, thus making a large change in the building. It is not necessary and the equipment cost can be reduced.
