[Second Embodiment] Next, a second embodiment will be described with reference to FIG. In this embodiment, instead of aligning the roving ends with the full bobbin lifter 11 provided in the pipe changer 9, for example, a roving bobbin is provided in front of the roving machine as in the device disclosed in JP-A-58-41919. Corresponding staggered pegs are arranged on the belt conveyor and a bobbin lifting device is installed at the end of the belt conveyor, and the bobbin lifting device is moved to the end by the belt conveyor and the full bobbins are paired front and rear by the transfer device. The present invention is significantly different from the above-mentioned embodiment in that it is applied to a device for delivering a full bobbin to a bobbin carrier by the ascending / descending movement of a bobbin lifting device. A bobbin lifting device 27 is provided on one side of the belt conveyor 26 provided on the front side of the roving machine, and a lifting member 28 of the bobbin lifting device 27 is equipped with a pair of pegs 29a, 29b. One peg 29b is rotatably mounted and is rotated by a motor 30 attached to the lower surface of the elevating member 28 so as to be movable integrally with the elevating member 28. In this device, the pair of front and rear full bobbins F transferred from the belt conveyor 26 to the pegs 29a and 29b of the elevating member 28 by a transfer device (not shown) have their roving ends 180 ° out of phase with each other. During the upward movement of the member 28, the one peg 29b is driven by the drive of the motor 30.
After being rotated, the positions of the roving ends of both full bobbins F are aligned at the same position, and then the bobbins are suspended from the bobbin hanger 6 of the bobbin carrier 7.

It should be noted that the present invention is not limited to the above-described embodiments, and for example, in the device of the first embodiment, instead of the configuration in which the peg 18b is rotationally driven via the gear 24 fixedly fitted to the shaft 22, As shown in FIG. 6, a driven pulley 31 is attached to the lower end of each stud 20, and a belt 33 is wound between the driven pulley 31 attached to the motor 25 and the driven pulley 31 to drive each peg 18b. May be.
Further, instead of rotating only one peg 18b, 29b by 180 degrees, both pegs 18a, 18b, 29a, 29b may be rotated by 90 degrees in opposite directions. Further, the bobbin lifting device is arranged at a position away from the roving frame, and the full bobbin lifted from the roving frame is mounted on the carrier to carry it to a position corresponding to the bobbin lifting device, and then it is transported at that position. It may be applied to a system in which a full bobbin is suspended on a bobbin carrier on a rail.

[Effects of the Invention] As described in detail above, according to the present invention, the roving ends of the full bobbin are automatically moved in the same direction while the full bobbin doffed by the roving machine is hung on the carrier by the lifting device. Since they are arranged in a uniform manner, it is not necessary to provide special time for aligning the roving ends. Further, in the full bobbin that is carried into the spinning machine in a state of being suspended from the carrier, all the roving yarn ends are arranged in the same direction, and roving splicing is performed during roving yarn replacement work by the roving yarn changer. Therefore, the mechanism for searching the position of the roving thread end becomes simple, and the trouble of finding the roving thread end is eliminated even in the case of manual roving thread splicing work, and the time required for the roving splicing work is shortened. The operating rate of the spinning machine is improved.
