[Industrial applications]

 The present invention relates to a traveler supply unit in a traveler insertion device used in a traveler exchange, which automatically replaces a traveler inserted in a ring of a ring spinning machine, and in particular, it has a cross section like a traveler in which a wire is bent in an ear shape. The present invention relates to a traveler supply unit that stores a non-flat traveler and allows one of the travelers to be detached when the insertion head holds the traveler.

[0002]

[Prior 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 drafting mechanism 103. The draft mechanism 103 has a back roller 104, a middle roller 106 having an apron 105, and a pair of upper and lower rollers of a front roller 107 arranged in order from top to bottom, and an upper roller of each roller pair is supported by a cradle arm so as to be opened and closed. 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 on which a bobbin 2 is inserted, a ring rail 4 which 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. The spindle shaft 1 is a belt 3 common to a plurality of weights and normally rotates at a high speed of about 1 to 20,000 RPM. The yarn Y is wound on 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, runs on the ring 5, and twists 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 frictional resistance bodies for producing a difference in rotation number, and at the same time, they are a traveling direction converting mechanism for converting the twisting action into the winding action.

The ordinary traveler 7 has a shape in which an elongated plate is bent into a C-shape, and the opening 7 a is pushed open to be attached to the ring 5. This traveler 7 wears because it rotates on the ring 5 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 into 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 forward. ing. In addition, the extension of the rod member is a magazine rod into which a number of travelers are inserted, and one traveler can be cut from the magazine rod to the tip of the rod member.

[0004]

[Problems to be solved by the device]

 However, the shape of the traveler 7 is not limited to a long and thin plate bent into a C shape, and as shown in FIG. 6, a ring finer that uses a traveler whose cross section is not flat like the traveler 6 in which the wire is bent into an ear shape. Some spinning machines also exist. Since this 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. Moreover, since the posture is not determined, the rod member cannot be used also as the magazine rod. Therefore, there is a problem that the traveler 6 in which the wire is bent in 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 whose cross section is not flat, such as a traveler in which a wire is bent into an ear shape. It is an object of the present invention to provide a traveler supply unit in a traveler insertion device in which a supply unit is separated from an insertion head and a traveler can be reliably separated from the traveler supply unit to the insertion head.

[0006]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the traveler supply unit in the traveler insertion device of the present invention is a traveler supply unit that allows one traveler to be detached when the insertion head clamps the traveler. It is provided for the magazine guide that holds it in the inserted state and at least one traveler that is detached from the tip of the magazine guide, to prevent movement by the insertion head in the direction opposite to the detachment direction and allow movement in the detachment direction. It is provided with a traveler guide.

[0007]

[Action]

 The traveler is stored while it is inserted in the magazine guide, and there is no magazine guide in the part where the insertion head separates one of the travelers. Instead, the movement of the insertion head in the anti-separation direction is blocked, and the travel direction The traveler guide that allows the movement to hold the traveler, the traveler does not escape when the inserting head holds the traveler, and the traveler after holding does not get caught and leaves the supply part together with the inserting head.

FIG. 2A is a side view, FIG. 2B is a top view, and FIG. 3 is a side view showing a state in which the insertion head receives the traveler from the traveler supply unit.

First, the entire traveler insertion apparatus will be described with reference to FIG. The traveler inserting device is configured by attaching an inserting head 12 and a traveler supply unit 13 to a main body casing 11. The traveler inserting device is mounted as one of the traveler exchanging devices of the traveler exchanging device M which can travel along the ring spinning machine. By the way, as will be described in detail below, the insertion head 12 is rotatably supported by the main body casing 11. The traveler supply unit 13 is supported by the main body casing 11 so as to be movable in the axial direction. The main body casing 11 is attached to the tip of a swing lever 15 having a shaft 14 as a fulcrum, and the swing lever 15 is biased toward a cam 16 by a tension spring (not shown). A roller 17 is provided in the middle of the swing lever 15, and the roller 17 rolls on the cam 16. When the cam 16 makes one revolution, the main body casing 11 can repeat the forward / backward movement as indicated by arrows a, b, and c in order to insert the traveler 6 sandwiched by the insertion head 12 into the ring 5. A large number of cams are fitted into the shaft 18 of the cam 16, and the cams that rotate with the shaft 18 are used to operate traveler replacement devices other than the traveler insertion device, such as traveler removal devices and thread shifting levers, at predetermined timings. It is supposed to do.

In FIG. 2, the insertion head 12 is a rod 23 in which two sandwiching members 21 and 22 are superposed. The rod 23 is inserted into the discs 24 and 25 of the main body casing 11, is not slidable in the axial direction by the plates 26 on both sides of the disc 24, and is rotatably supported by the main body casing 11. The rod 23 is biased in the rotation direction by a coil spring 27, but the rotation angle is restricted by the pin 28 hitting a guide 37 described below. Normally, as shown in the figure, the rotation angle of the rod 23 is regulated so that the traveler 6 clamped by the clamp members 21 and 22 faces downward.

The traveler supply unit 13 is a magazine guide 31 having an L-shaped cross section in which a large number of travelers 6 are inserted in a row so as to fall in the direction of their own weight. This magazine guide 31 is fixed to a slide disk 34 via arms 32 and 33. The slide disc 34 is inserted into the rod 23 so as to be slidable in the axial direction, and is prevented from rotating by a guide rod 35. A tension spring 36 is provided between the slide disk 34 and the disk 25, and the slide disk 34 is retracted to a position where it abuts on the stopper 35a of the guide rod 35. Furthermore, a guide 37 for changing the direction of the pin 28 from the slide disk 34 is provided in a protruding manner.

In the traveler insertion device having the above-described structure, as shown in FIG. 3, the arm 32 extending from the slide disk 34 is provided while the main body casing 11 is returning to the predetermined position of the traveler exchange as indicated by the arrow d. When it hits the stopper 38 on the traveler exchange side, the tension spring 36 extends and only the rod 23 moves in the direction of arrow d. Then, the direction of the pin 28 is changed by the guide 37 that is provided so as to project on the slide disk 34, and the rod 23 is rotated so that the tips of the pinching members 21 and 22 are substantially sideways on the front side. Further, the tips of the holding members 21, 22 approach the tip of the traveler supply unit 13, and the holding members 21, 22 receive one of the travelers 6 from the tip of the traveler supply unit 13. The reason why the holding members 21 and 22 of the insertion head 12 are rotatable in this way is as follows. In order to improve the flow of the traveler 6 inserted into the magazine guide 31 of the traveler supply unit 13, the magazine guide 31 needs to be oriented in the direction in which the traveler 6 falls by its own weight. 6 is preferably substantially horizontal. However, the posture of the traveler 6 on the holding members 21 and 22 when inserted into the ring is vertically downward. Therefore, the holding members 21 and 22 are rotated in a substantially horizontal direction to receive the substantially horizontal traveler 6 at the tip of the magazine guide 31.

Next, details of the holding members 21 and 22 of the insertion head 12 will be described with reference to FIG. The nipping member 22 is formed with a blade 41 as one of the tips of the traveler 6 and a separating portion for separating the other end. The holding member 21 is formed with a pair of blades 41 and a taper 42 for facilitating reception of the traveler 6 at the tip.

The movement restricting member is formed on the surface of the holding member 22, and includes a groove portion 43 corresponding to the bending of the upper ear of the traveler 6 and an inclined portion 44 formed inside the groove portion 43 and reaching the groove portion 43. Has become. The holding members 21 and 22 separate the traveler 6 at the tip, and the upper part on the ear side moves as shown by the arrow e and is held by the holding members 21 and 22. Even if the sandwiched portion of the traveler 6 is a part of the upper part on the ear side, it is dropped into the groove 43 by the inclined portion 44 as shown by the arrow f, fitted in the groove portion 43, and regulated by this groove portion 43. Stabilize in posture. Further, when the traveler 6 is inserted into the ring, the traveler 6 clamped in a stable posture by the groove portions 43 of the clamping members 21 and 22 is smoothly removed due to the presence of the inclined portion 44.

Next, details of the traveler supply unit 13 will be described with reference to FIG. 7A is a sectional view of the traveler 6 at the front end, FIG. 8B is a sectional view of the traveler 6 second from the tip, and FIG. 7C is a sectional view of the traveler 6 on the upper side. As shown, a leaf spring 51, a first traveler guide 52, and a second traveler guide 53 are provided at the tip of the magazine guide 31 into which the traveler 6 is inserted. The leaf spring 51 normally contacts the first and second traveler guides 52 and 53 to prevent the traveler 6 from falling, and the holding member (not shown) allows the leaf spring 51 to escape when the traveler 6 at the tip comes off. ing. The first traveler guide 52 is a metal fitting having a concave cross section for receiving the upper bend 6a of the traveler 6, and the second traveler guide 53 is a metal fitting having an L-shaped cross section for receiving the lower bend of the traveler 6. Further, as shown in FIG. 9A, the magazine guide 31 does not exist for the traveler 6 at the tip.

Further, referring to FIG. 6, the detachment of the traveler 6 at the tip end to the holding members 21 and 22 will be described. FIG. 6A is a front view, and FIG. 6B is a top view of the traveler at the tip. The traveler 6 at the tip can support the reaction force in the anti-separation direction g when the sandwiching members 21 and 22 are sandwiched by the first and second traveler guides 52 and 53, and the inclined portion when sandwiched by the sandwiching members 21 and 22. The traveler 6 is released from the recessed space of the first traveler guide 52 by the downward movement in the detaching direction f through the groove 44 to the groove 43. As a result, the traveler 6 at the tip is carried while being held by the holding members 21 and 22. Then, the next Traveler 6 is lowered by its own weight. Further, in order to ensure the detachment of the traveler 6 at the tip, the surfaces of the holding members 21 and 22 and the surface of the leaf spring 51 are inclined by an angle θ, and the holding members 21 and 22 are biased by the leaf spring 51. By overcoming, the traveler 6 at the tip of the magazine guide 31 is tilted in the h direction to help the traveler 6 separate from the traveler guides 52, 53.
