Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a traveler mounting device provided in a traveler changing machine for automatically changing a traveler fitted to a ring of a ring spinning machine.

[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 includes 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 can be opened and closed by a cradle arm. And the lower roller of each roller pair is driven. The sliver S or the roving yarn S having a large diameter becomes a yarn through the draft mechanism 103. This yarn is spun through a twisting mechanism 102 described below.

The twisting mechanism 102 includes a spindle shaft 11 into which the bobbin 12 is inserted, a ring rail 14 that is vertically movable and traversable along the longitudinal direction of the bobbin 12, and a ring fixed to the ring rail 14. 15, a traveler 7 attached to the ring 15 and movable in the circumferential direction, a balloon control ring 9, and a snell wire 8 are arranged from bottom to top.

The spindle shaft 11 is normally rotated at a high speed of about 10,000 to 20,000 RPM by a belt 13 common to a plurality of weights. The yarn Y is wound on the bobbin 12 via the snell wire 8, the balloon control ring 9 and the traveler 7. When the bobbin 12 rotates, the traveler 7 is pulled by the hung upper yarn Y1 and lower yarn Y2, runs on the ring 15, and twists the yarn. There is a difference in rotation speed between the bobbin 12 and the traveler 7 by an amount corresponding to the length of the yarn sent from above, and the bobbin 12 is wound by this length. That is, the ring 15 and the traveler 7 are a frictional resistance body for producing a difference in the number of rotations, 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 an overall length of 5 mm and a width of less than 1 mm, and is usually C-shaped or clamp-shaped, and is attached to the ring 15. This traveler 7 is worn because it rotates on the ring 15 at a high speed of around 10,000 to 20,000 RPM. Therefore, the traveler 7 is replaced with a new one every 1-2 weeks. Normal traveler replacement is done by hand. Using an appropriate claw fitting, insert this claw fitting into the gap between the traveler 7 and the ring 15, move the claw fitting in the direction to widen the gap, and remove the old traveler. , Had a new traveler attached. Therefore, if all the travelers of the ring spinning machine having a large number of spindles are replaced, even a skilled person will need a considerable amount of time.

[0007] Therefore, it has been desired to automatically exchange travelers by a traveler exchange equipped with a traveler exchange such as a traveler removing device or a traveler attaching device. In order to automatically change the traveler in this way, a traveler changer is proposed, in which the upper thread and the lower thread hung on the traveler are moved so as to intersect on the ring, and then the traveler removing device and the traveler attaching device are operated. Has been done.

A conventional example of a traveler mounting device used in this traveler exchange will be described with reference to FIGS. 7 and 8. FIG. 7 is a perspective view of a main part, and FIG. 8 is a mounting state view. The main part of the traveler mounting device 23 is composed of a guide member 36 into which a large number of the travelers 7 are fitted, a cutout member 37, and a leaf spring 38. The guide member 36 guides each traveler to one end side in order to attach a new traveler to the ring of the ring spinning machine. Then, by moving the cutting member 37 in the direction, one of the travelers 7 of the guide member 36 is pressed and fed to the tip. As shown in FIG. 8, the tip 36a of the guide member 36 is bent, and the traveler is held in a vertical C-shape. Then, when the whole of the traveler attaching device 23 is retracted in the direction, the end of the traveler 7 is extended and disengaged from the tip end 36a to be fitted and attached to the flange 6 of the ring. At the same time, the leaf spring 38 shown in FIG. 7 causes the free traveler 7 to be blown away to the back side in the thickness direction of the paper.

[0009]

[Problems to be solved by the device]

 By the way, if this traveler mounting device is loaded on a traveler exchange and the travelers for a number of ring spinning machines are automatically exchanged, a large amount of travelers are consumed. Since the amount of the traveler fitted into the guide member 36 in FIG. 8 is small, a rod member in which the traveler is fitted in a row is detachably attached to the end of the guide member 36 in a cassette type, and the rod member is replaced to replace the traveler member. Something to supply is suggested. However, there is a limit to the length of the cassette type bar that can be connected to the traveler mounting device, and there is a problem that it is often necessary to replace the bar.

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 that can store a large number of travelers and sequentially supply a required number of travelers. There is a mounting device provided.

[0011]

[Means for Solving the Problems]

 The traveler mounting method that achieves the above object is a traveler mounting device that holds the traveler at the tip and attaches it to the ring, and has a guide member that holds the traveler, and the guide member is in the state where the traveler is fitted. The driving means is connected to the cord stored in 1. and pulls an empty cord so as to transfer one traveler from the cord to the guide member in association with the operation of attaching the traveler.

[0012]

[Action]

 When the strap is stored with the traveler fitted, a large amount of the traveler is stored by winding the strap around the reel, and when the strap is pulled by the drive means that works in conjunction with the traveler's mounting operation, the traveler is Traveler corresponding to the traveler consumed by the mounting operation of is supplied to the guide member.

【Example】

 Embodiments of the present invention will be described below with reference to the drawings. 1 is an overall side view of a traveler mounting device of the present invention, FIG. 2 is a sectional view taken along line XX of FIG. 1, and FIG. 3 is a sectional view taken along line YY of FIG.

In FIG. 1, the guide member 36 is oriented obliquely downward, and the traveler 7 guided by the guide member 36 advances toward the tip 36 a by its own weight and stops slightly before the cutout member 37. . A parallel rod 50 is attached to the guide member 36, and the parallel rod 50 is held by the guide rollers 52 and 53 of the main body 51 so as to be slidable in the axial direction. Further, a tension spring 52 is attached between the parallel bar 50 and the main body 51, which is normally in the state shown in the drawing, but when the traveler 7 at the tip is caught by the ring 15 and the main body 51 retreats in the direction, the guide member 36 is removed. It protrudes from the main body 51. The main body 51 is attached to an arm 53, and the arm 53 moves back and forth with respect to the ring 15 by a cam mechanism (not shown). The illustrated example shows a state in which the ring 7 has been advanced to just install the traveler 7.

As shown in FIG. 2, the traveler 7 is fitted into the rubber cord 55, and the guide member 36 is inserted between the rubber cord 55 and the traveler 7. Then, when the rubber cord 55 is pulled in the direction, the rubber cord 55 is deformed and disengages from the guide member 36, and the traveler 7 is transferred to the guide member 36 and stored therein. The rubber cord 55 fitted with the traveler 7 is wound around the reel 56, and the empty rubber cord 55 'from which the traveler 7 is removed is wound around the reel 57. The reels 56 and 57 are urged in the winding direction like a tape measure and rotatably supported by the arm 53.

The empty rubber cord 55 ′ is sandwiched between the driving roller 58 and the driven roller 59. The rollers 58 and 59 are axially supported by the plate 54 at the rear end of the parallel rod 50. In particular, the drive roller 58 is driven via the first link 60 and the second link 61. The second link 61 has a rotation fulcrum on the main body 51 side, and the first link 60 has a rotation fulcrum on the drive roller 58 side.

As shown in FIG. 3, the drive roller 58 is supported by the tubular body 60 a of the first link 60 via a one-way clutch 62 that is free rotation and lock rotation shown in the drawing. The tubular body 60a is axially supported by a shaft 64 via a bearing 63. The driven roller 59 is rotatably supported by a shaft 66 via a one-way clutch 65 that performs free rotation and lock rotation as illustrated. Each of the rollers 58 and 59 has grooves 67 and 68 to which rubber is attached, and the rubber cord 55 ′ is sandwiched between the grooves 67 and 68.

Next, the operation of the traveler mounting device described above will be described with reference to FIG. When the main body 51 withdraws in the direction with the traveler 7 mounted on the ring 15, the guide member 36 relatively projects from the main body 51 while elastically deforming the traveler 7. Then, the first link 60 and the second link 61 rotate in the directions shown in the drawing, and the drive roller 58 pulls the empty rubber cord 55 'through the one-way clutch 62 of FIG. The pulling amount is adjusted so that one of the travelers 7 can be transferred to the guide member 36. The driven roller 59 is locked in rotation in the direction via the one-way clutch 65 shown in FIG. 4, and the empty rubber cord 55 'holds the pulled state. When the traveler 7 is disengaged from the tip 36a and fitted into the ring 15, the tension spring 52 returns the guide member 36 to the state shown in FIG. 1, and the links 60 and 61 also rotate in the opposite direction, but the drive roller 58 does not move. The one-way clutch 65 of No. 3 does not rotate and remains stopped. That is, the driven roller 59 serves as a back stop and prevents the drive roller 58 from rotating in the reverse direction. Then, only the tangential force in the delivery direction is transmitted to the emptied rubber cord 55 '.

In this way, the rubber cord 55 is pulled in association with one time of the traveler attaching operation of the guide member 36, and one of the travelers is supplied to the guide member 36. Further, the traveler 7 is wound around the reel 56 while being fitted in the rubber cord 55, so that a large amount of the traveler 7 can be supplied. Therefore, it is not necessary to frequently replenish the travelers of the traveler exchange.

Next, an example of the operation unit 31 in which the traveler exchanging device including the above-mentioned traveler removing device is mounted will be described with reference to FIGS. 5 and 6. 5 is a front view of the operating unit 31, and FIG. 6 is a top view of the operating unit. . The operating unit 31 is supported by a bogie unit (not shown) so as to be lifted and lowered, and is movable along the ring rail 14. The operating unit 31 is divided into three stations S1, S2 and S3. The station S1 is provided with a positioning plate 26, a roller 33 and a lever 27, and the station S2 is provided with a recovery box 32, a roller 28, a tensor 30, a thread shifting lever 1, a traveler removing device 17 and a traveler mounting device 22. Therefore, the station S3 is provided with a roller 29 and a slack eliminating device 34.

The traveler exchange procedure by the operation unit 31 is as follows. The station S1 loosens the thread, the station S2 replaces the traveler, and the station S3 tensions the thread. At the station S1, the roller 33 is located on the central bobbin 12, and the central bobbin 12 is reversed to loosen the yarn. Then, the operating unit 31 travels one pitch P to the left side of the drawing, and the station S2 is in the illustrated state.

At this time, the lever 27 slightly moves the traveler 7 so that the traveler 7 is removed from the position where it interferes with the operating position of the traveler removing device 17 described below. Then, the positioning plate 26 advances and is fitted into the ring 15 to be positioned. Next, the yarn Y is stored by the tensor 30, and the yarn Y can be fed or fed with a predetermined yarn tension. Then, the tip of the traveler removing device 17 advances onto the ring 15, the roller 28 rotates the bobbin 12 in the forward direction to run the traveler 7, and the traveler 7 is hooked on the tip of the traveler removing device 17. Next, the thread shifting lever 1 moves the thread across the ring 15, and the traveler removing device 17 removes the old traveler 7 and puts it in the collection box. Thereafter, the traveler attachment device 22 fits the new traveler 7 onto the ring 15 as described above. Then, the tensor 30, the yarn pulling lever 1, the traveler removing device 17, and the traveler attaching device 22 are retracted, and the operating portion 31 travels one pitch P to the left side in the drawing. Then, the roller 29 rotates the bobbin 12 in the forward direction to wind up the loosened yarn Y, and the looseness removing device 34 makes the yarn completely stretched.
