Spare rails that form guide rails along the longitudinal direction of the spinning frame 1 at the front ends of the creel 20.
A spare rail 24 is attached to the spare rail 24. The spare rail 24 is branched from a main rail, which constitutes a guide rail connected to the upper part of the frame of the roving machine (not shown), and guides a known bobbin carriage 26 so that the bobbin carriage 26 can travel freely. The bobbin carriage 26 is constituted by connecting a plurality of carriage bars 26a having a required number of bobbin hangers 27 on the lower side as shown in FIG. 3 as disclosed in Japanese Patent Laid-Open No. 63-101284. ,
A pair of horizontal support rollers 28 provided on the upper side of each carriage bar 26a are guided on a support surface 24a of a main rail or a spare rail 24 (not shown), and a vertical guide roller 29 is guided on a guide surface 24b. 32 is a well-known transfer device in which a large number of rails are arranged on the rail at a pitch interval shorter than the length of the bobbin carriage 26. As shown in Japanese Patent Laid-Open No. 63-101284, a pair of feed rollers 34 are mounted on a carriage by a spring 37. It is configured so that it is pressed against the bar 26a and one of the feed rollers 34 can be rotated forward and backward by the drive motor M. A pair of brackets 40 extending below the full roving bobbin 6a (or the residual thread bobbin) suspended on the bobbin hanger 27 of the bobbin carriage 26 are fixed to the upper surface of the spare rail 24 at the entrance of the spinning machine 1, In the lower part of each bracket 40, a throwing device exemplified as a detecting device for detecting Shino S hanging from the full roving bobbin 6a,
The light receivers 41 and 42 are fixed to face each other. The projecting / receiving devices 41, 42 are provided at a height position between the lower end of the bobbin suspended on the bobbin carriage 26 and the upper end of the out-end box 7, and are in front of the draft part 5 of the spinning machine 1. It is provided on the side. When the light between the projector and the receiver 41, 42 is blocked by the Shino S, the signal is transmitted to the control box 45 (Fig. 2) and the control box
45 is a transfer device on the inlet side of the spinning machine 1 depending on the signal input.
