2. Description of the Related Art First, a ring spinning machine in which a traveler is used will be described with reference to FIG. The ring spinning machine 101 has a twisting mechanism 102 and a draft mechanism 103. The draft mechanism 103 includes a back roller 104, an apron 105
Middle roller 106 having front and front roller 1
07 upper and lower roller pairs are arranged in order from top to bottom, the upper roller of each roller pair is supported by a cradle arm so as to be openable and closable, and the lower roller of each roller pair is driven. The large-diameter sliver S or roving yarn S becomes a yarn via the draft mechanism 103. This yarn is spun through a twisting mechanism 102 described below. The twisting mechanism 102 includes a spindle shaft 1 into which the bobbin 2 is inserted, a ring rail 4 that is vertically movable and traversable along the longitudinal direction of the bobbin 2, and a ring 5 fixed to the ring rail 4. A traveler 7, which is attached to the ring 5 and can travel in the circumferential direction, a balloon control ring 9, and a snell wire 8 are arranged from bottom to top. Spindle shaft 1 is belt 3 common to multiple weights
It usually rotates at a high speed of around 10,000 to 20,000 RPM. Thread Y
Is wound onto the bobbin 2 via the snell wire 8, the balloon control ring 9 and the traveler 7. As the bobbin 2 rotates, the traveler 7 is pulled by the yarn and runs on the ring 5 to impart twist to the yarn. There is a difference in rotation speed between the bobbin 2 and the traveler 7 by an amount corresponding to the length of the yarn sent from above, and the bobbin 2 is wound by this length. That is, the ring 5 and the traveler 7 are a frictional resistor for generating a rotational speed difference, and at the same time, a traveling direction changing mechanism for changing the twisting action to the winding action.

The traveler 7 is a small metal fitting having a total length of 5 mm and a width of less than 1 mm, and is usually C-shaped or clamped, and is inserted into the ring 5. Since the traveler 7 rotates at a high speed of about 10,000 to 20,000 RPM on the ring 5, it wears out. So every 1-2 weeks, Traveler 7
Need to be replaced from old to new. Conventionally, this traveler exchange has been performed manually, and automation by a traveler exchange machine has been desired.
