2. Description of the Related Art First, a ring spinning machine using a traveler will be described with reference to FIG. The ring spinning machine 101 has a twisting mechanism 102 and a drafting mechanism 103. The draft mechanism 103 includes a back roller 104 and 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 thread S becomes a thread through 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. When 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 resistance body for producing a difference in the number of revolutions, and at the same time, a traveling direction changing mechanism for changing the twisting action into the winding action.

The ordinary traveler 7 has a shape in which a slender plate is bent into a C-shape, and the opening 7a is expanded and inserted into the ring 5. This Traveler 7 is Ring 5
Wears because it rotates at a high speed of around 10,000 to 20,000 RPM. Therefore, it is necessary to replace the traveler 7 with an old one every 1-2 weeks. Therefore, a new traveler 7 is inserted and attached to the rod member whose tip is bent by using a traveler insertion device that biases and holds the opening 7a of the traveler 7 with a spring member so that the opening 7a faces the front side. There is.

[0004]

However, the shape of the traveler 7 is not limited to the elongated plate bent in a C shape, and the cross section thereof is the same as the traveler 6 in which the wire is bent in an ear shape as shown in FIG. Some ring spinning machines also use non-flat travelers. Since the traveler 6 does not have a flat portion in the width direction, the posture cannot be kept constant by the bar member having the bent tip and the spring member. Therefore, there is a problem that the traveler 6 in which the wire is bent into an ear shape is manually inserted and is time-consuming to insert.

The present invention has been made in view of the above problems of the prior art, and an object of the present invention is to provide a traveler having a flat cross section, such as a traveler in which a wire is bent in an ear shape. On the other hand, it is intended to provide a traveler insertion device capable of reliably maintaining its posture.

[0006]

In order to achieve the above-mentioned object, a traveler inserting device of the present invention is capable of advancing and retracting with respect to a ring into which a traveler is inserted and holding two upper holding members of the traveler. And a traveler movement restricting member that is provided between the sandwiching members to maintain the posture of the sandwiched traveler.

[0007]

[Function] When the traveler is sandwiched by two sandwiching members, the posture is determined even by a traveler having a flat cross section like a traveler having a bent wire, and the traveler movement restricting member provided between the sandwiching members maintains the posture of the traveler. It
