Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a traveler inserting device used in a traveler exchanging machine for automatically exchanging a traveler attached to a ring of a ring spinning machine, and particularly to a traveler having a flat cross section such as a traveler in which a wire is bent into an ear shape. For things that can be inserted automatically.

[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 and runs on the ring 5 to impart twist to the yarn. There is a difference in the number of rotations 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 members for producing a difference in rotation speed, and at the same time, they are a traveling direction changing mechanism for changing the twisting action to 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. Since this traveler 7 rotates on the ring 5 at a high speed of about 10,000 to 20,000 RPM, it is worn. Therefore, it is necessary to replace the Traveler 7 with a new one every 1-2 weeks. Therefore, a new traveler 7 can be inserted and attached to the rod member whose front end 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. It is being appreciated. 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 out from the magazine rod at 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 the elongated plate bent into a C-shape, and a ring-shaped structure using a traveler whose cross section is not flat like the traveler 6 in which the wire is bent into an ear shape as shown in FIG. 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 in an ear shape. On the other hand, it is not intended to provide a traveler insertion device that can reliably hold its posture and can reliably receive the traveler from the traveler reservoir.

[0006]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the traveler inserting device of the present invention comprises a magazine guide for holding the traveler in a state in which it is inserted in a direction in which it falls by its own weight, and two pieces of the traveler that sandwich the traveler in a vertical posture inserted in a ring. An inserting head having a sandwiching member is provided, and the inserting head is rotatable and receives a traveler by approaching the magazine guide tip while changing its posture. Further, a traveler separating portion is provided in the portion of the holding member that approaches the magazine guide, and the holding member approaches in a lateral direction with an inclination angle so that the traveler at the tip of the magazine guide is tilted outward. Is preferred.

[0007]

[Action]

 A traveler that improves the flow of the traveler with a magazine guide that keeps the traveler inserted in the direction in which it falls by its own weight, and a traveler with a flat cross section like a traveler that has a wire with a circular cross section to sandwich the traveler with two clamping members However, the posture is determined, but since the posture of the sandwiching member that inserts the traveler into the ring and the posture of the sandwiching member that receives the traveler at the tip of the magazine guide are different, the insertable head with the sandwiching member can be rotated to change the posture. However, when approaching the sandwiching member, the traveler inserted in the direction of falling by its own weight can be received. Further, if the traveler separating portion is provided on the holding member, it is easy to separate the traveler at the tip of the magazine guide. You will receive it while tilting it, and you will be sure to detach it from the tip of the traveler's magazine guide.

 Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view of a main part of a traveler exchange using the traveler insertion device of the present invention, FIG. 2 is a view showing the traveler insertion device of the present invention, and FIG. 2 (b) is a top view, and FIG. 3 is a side view showing a state where the traveler insertion device receives the traveler from the traveler reservoir.

In FIG. 1, the traveler insertion device has an insertion head 12 and a traveler reservoir 13 attached to a main body casing 11. The traveler inserting device is installed 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 described in detail below, the insertion head 12 is rotatably supported with respect to the main body casing 11. The traveler reservoir 13 is supported by the 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 rotation, 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 heads 12 into the ring 5. A large number of cams are fitted on the shaft 18 of the cam 16, and a traveler rotating device such as a traveler removing device other than the traveler inserting device or a thread shifting lever is a predetermined timing with a cam that rotates together with the shaft 18. It is designed to work with

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 reservoir 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 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 inserting apparatus having the above-described structure, as shown in FIG. 3, the arm 23 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 projectingly provided on the land disc 34, and the rod 23 is immediately rotated so that the tips of the pinching members 21 and 22 are in a substantially horizontal posture on the front side. Further, the tips of the sandwiching members 21, 22 approach the tip of the traveler reservoir 13, and the sandwiching members 21, 22 receive one of the travelers 6 from the tip of the traveler reservoir 13. The reason why the holding members 21 and 22 of the insertion head 12 are rotatable and the posture is changed is as follows. In order to improve the flow of the traveler 6 inserted in the magazine guide 31 of the traveler reservoir 13, the magazine guide 31 needs to be oriented in the direction in which the traveler 6 falls due to its own weight. The traveler 6 is preferably substantially horizontal. However, the posture of the traveler 6 in 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 sideways posture so that the substantially horizontal traveler 6 at the tip of the magazine guide 31 can be received.

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. Further, a movement restricting member for maintaining the posture of the traveler is provided between the holding members 21 and 22. 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 shape of the traveler 6, and an inclined portion 44 formed inside the groove portion 43 and reaching the groove portion 43. ing. The sandwiching members 21 and 22 separate the traveler 6 at the tip, and the upper part on the ear side moves as shown by an arrow e and is sandwiched by the sandwiching members 21 and 22. Even if the sandwiched portion of the traveler 6 is a part of the upper portion on the ear side, it is dropped into the groove 43 by the inclined portion 44 as shown by the arrow f, fitted into the groove portion 43, and regulated by the groove portion 43. Be stable with your appearance. 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 existence of the inclined portion 44. It should be noted that the inclined portion 44 with respect to the groove portion 43 as the movement restricting member is not always necessary. Further, the groove 43 is not limited to being provided on one of the sandwiching members 21 and 22, and a thin plate having a notch corresponding to the groove 43 may be provided between the sandwiching members 21 and 22.

Next, the details of the traveler reservoir 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 separation assisting member 52, and a second separation assisting member 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 separation assisting members 52 and 53 to prevent the traveler 6 from dropping, and the holding member (not shown) allows the leaf spring 51 to escape when the traveler 6 at the leading end comes off. Has become. The first release assisting member 52 is a metal fitting having a concave cross section that receives the upper bend 6a of the traveler 6, and the second release assisting member 53 is a metal fitting having an L-shaped cross section that receives the lower bend of the traveler 6. . Further, as shown in FIG. 7A, 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 g direction when the sandwiching members 21 and 22 are sandwiched by the first and second separation assisting members 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 separation assisting member 52 by the falling movement in the f direction 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 goes down 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, 22 and the surface of the leaf spring 51 are inclined by an angle θ, and the holding members 21, 22 are biased by the leaf spring 51. And the traveler 6 at the tip of the magazine guide 31 is tilted in the h direction to help the traveler 6 detach from the detachment assisting members 52, 53.
