CONSTITUTION:In a silver ending machine intermittently moving along the row of spindles of a ring spinning frame equipped with a slub catcher and carrying out sliver ending in front of each spindle, the sliver ending machine is equipped with a yarn guide member 55 to introduce spun yarn to the lower part of slub catchers 16 during sliver ending and a means 56 to transfer the member. Consequently, even if ballooning of spun yarn is enlarged, the spun can be prevented from being caught by the slub catchers 16.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention moves intermittently along the spindle row of a ring spinning frame, and at each spindle position, the roving yarn of the full bobbin is prepared in advance for the yarn of the small bobbin being spun. The present invention relates to a splicing machine for a ring spinning machine that is designed to splice.

Conventional technology Conventional 4 This type of Shino joint machine is disclosed in Japanese Patent Application Laid-Open No. 62-53425.
As shown in the publication, when the Shinomaki bobbin in the front row of the creel becomes a small bobbin, the machine table moves intermittently from one end side to the other end to prepare threads for multiple small bobbins in advance. As shown in Japanese Unexamined Patent Publication No. 63-57478, every other Shinomaki bobbin in two rows at the front and back of the creel became a small bobbin. It is known that the machine moves intermittently from one end to the other end of the machine and splices two roving threads, one front and one back, onto a full bobbin braid prepared in advance on a spare rail. In order to prevent the pipe yarn from becoming full during the work, the Shino-joining work using the above-mentioned Shino-jointing machine starts before the pipe yarn reaches a 5-minute or 6-minute ball, and the pipe yarn becomes full. I manage to finish all the work beforehand. Shino splicing using the above-mentioned Shino splicing machine is performed by overlapping the roving end of a full bobbin on the roving end drawn into the draft section. As the spun yarn becomes thicker, the spun yarn at the spliced part becomes thicker, and as a result, the ballooning of the spun yarn at the spun joint part becomes abnormally large. The thread will get caught and breakage will occur. Therefore, conventionally, in order to prevent yarn breakage during the above-mentioned splicing, the rotation speed of the spindle of the ring spinning machine was lowered to prevent the ballooning of the spun yarn from increasing, or to prevent the spun yarn from getting caught in the slab catcher. In order to make it more difficult, we have devised the timing for the Shino-joining machine to perform the Shino-joining work when the winding bobbin of the pipe yarn has grown to about a 5-minute bobbin size and the anti-node ring has approached the size of the Snell wire. This is the reality.

Problems to be Solved by the Invention When splicing with a splicing machine, reducing the rotational speed of the spindle in order to prevent thread breakage at the spliced part reduces the productivity of the ring spinning machine. There is a big problem, and starting the Shino-joining work after the number of rolled balls of yarn becomes large shortens the time from the start of Shino-joining to the time when the yarn becomes full. As a result, if the ring spinning machine has a large number of spindles, the pipe yarn will become full before the splicing is completed, which is a problem that cannot be handled by recent long spinning machines with over 900 spindles. Therefore, one object of the present invention is to solve the above-mentioned problems, to prevent yarn breakage at the spliced part during splicing without lowering the rotational speed of the spindle of a ring spinning machine, and to be able to also be applied to a long ring spinning machine. It is an object of the present invention to provide a spinning machine for a spinning machine that can be fully used.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention aims to prevent the spun yarn from falling under the slab catcher even if the ballooning of the spun yarn becomes large in the operating position in the spun splicing machine of the ring spinning machine. It is characterized by comprising a yarn guide member that can be guided to the side, and a moving device that can move the yarn guide member from a standby position to an operating position while the spliced portion of the roving is being spun. .

Operation When the splicing machine performs splicing work at each spindle position, the opening guide member, which spins the spliced portion of the braided yarn and winds it into a pipe yarn, is moved from the standby position to the operating position by the movement position. Ballooning increases when the spun joint part of the braided yarn is spun, but the spun yarn is guided by the yarn guide member so that it does not get caught in the slab catcher of the ring spinning machine, so the spun yarn does not get caught in the slab catcher of the ring spinning machine. It is wound around the tube yarn so as to guide it downward, and even if the ballooning of the spun yarn becomes large, the occurrence of yarn breakage can be prevented.

The pet angle 12 rises as the lifting range of the ring rail 7 rises, that is, as the winding of the tube yarn 6 becomes larger, and adjusts the distance between the antinode ring 9 and the Snell wire 15 to a predetermined size. I try to keep it above that. Further, a well-known slab catcher 16 is integrally provided with the Snell wire 15, and when the ballooning of the spun yarn becomes large due to the generation of slabs due to the inclusion of fluff, etc., the spun yarn is caught by the slab catcher 16. hooked on and forcibly disconnected,

Furthermore, when the piston rod 63b is set in a free state, the thread guide 59 is allowed to fall under its own weight. The air cylinders 60 and 63 operate prior to the completion of the splicing to place the yarn guide 55 on the slab catcher 16, and operate in reverse to place the yarn guide 55 on the slab catcher 16 after the splicing is completed. It is intended to be operated in conjunction with Shinotsugu work to return it.

Next, the operation of the above-mentioned Shino connecting machine 2 will be explained.

First, when the bobbin suspended from the front row bobbin hanger 25 becomes the small bobbin 27, the winding amount of the tube yarn 6 is about 5 to 6 minutes (this winding amount is the number of spindles 5, that is, the ring spinning machine is used for spinning work). After confirming that the machine is in front of the machine (which varies depending on the length of time required for Working position, that is, the small bobbin 2 to be spliced by the splicing head 50
It is positioned and stopped at a position facing No. 7 roving 27a.

Next, the support head 41 of the connecting device 39 moves up and down as shown by the arrow in FIG.
2 onto the peg 43, and the outlet nozzle 47 is raised as shown by the arrow so that its suction port is located near the outer peripheral surface of the full bobbin 33 on the peg 43 and at the height of the roving end of the full bobbin 33. , apply suction force to the suction port. In this state, the full bobbin 33 is rotated to the unwinding side, and the full bobbin 33
The end of the braided thread is suctioned and held by the suction nozzle 47.

After that, the suction nozzle 47 descends to its original position and the full bobbin 33
The braided yarn is pulled down, and the roving end is guided to the tip of the sashimi head 50. Next, the Shinotsugi head 50 grips the roving and swings upward to cut the roving between it and the suction nozzle 47 into a brush tip shape, and then the Shinotsugi head 50 moves forward to separate the braided yarn. The roving yarn 27a introduced into the trumpet 11 is polymerized, and at the same time, the gripping of the braided yarn is solved and the roving yarn 27a is polymerized.
7a and cut the roving 27a. the result,
The cut end of the roving yarn of the full bobbin 33 overlaps the cut end of the braided yarn of the small bobbin 27 and is guided from the trumpet 11 to the draft section 10 and is then spliced.
is restored. After that, the lever 51 is moved up and down as shown by the arrow to lift the braided yarn of the full bobbin 33 upwards and hook it onto the roving guide 20, and the support head 43 rises to move the full bobbin 33 upward. Evacuate to. In this state, the exchange head of the Shino exchange device 40 moves to remove the small bobbin 27 from the front row bobbin hanger 25 and returns to its original position, and then the support head 43 (exchange head 52) moves to transfer the full bobbin 33 to the front row bobbin. hanger 2
5, the exchange head 53 moves again to insert the small bobbin 27 into the spare bobbin hanger 32, and then the exchange heads 52 and 53 return to their original positions.

On the other hand, before the braided yarn of the full bobbin 33 is spliced to the roving yarn 27a of the small bobbin 27, the piston rod 63b of the air cylinder 63 of the yarn guide device 54 protrudes, and the support rod 5
8 to raise each air cylinder 60 and yarn guide 55 to the lifting position, and in that state, the piston rod 60b of the air cylinder 60 protrudes, and the yarn guide 59 is moved above the corresponding slab catcher 16. After that, the piston rod 63b of the air cylinder 63 is placed in a free state, and the thread guide 55 is moved to the slab catcher 16 as shown in FIG.
drop it onto the tip of the device and move it to the operating position. Therefore,
The thread guide 55 is placed on the slab catcher 16 and is raised together with the slab catcher 16. As mentioned above, the thread guide 55 is the slab catcher 1.
6, the spliced portion of the roving spliced by the splicing operation described above is spun out from the draft section 10. The woven seam part of the roving is formed by the polymerization of two rovings.
Since it has returned to a length of about 7a1 and has become thicker, the spun yarn at the shinosetsugi part will be 1.1 when the draft is about 30 times, for example.
The yarn becomes thicker over a length of approximately 5 m to 2.1 m, and ballooning of the spun yarn becomes large in that portion. When the ballooning of the spun yarn increases in this manner, the spun yarn tends to be caught at the tip of the slab catcher 16, as is clear from FIG. However, in this embodiment, since the yarn guide 55 is placed on the slab catcher 16 as described above, even if the ballooning of the spun yarn becomes large, the spun yarn is guided as shown in FIG. The spun yarn is guided to the lower side of the slab catcher 16 by the lower surface of the shaft 55, so that the spun yarn is not caught by the slab catcher 16, and the spun yarn is cut by the slab catcher 16 as a roving.

The time it takes for the spliced portion of the roving to be wound around the pipe yarn 6 is about 6 to 8 seconds at most (the faster the rotation speed of the spindle 5 is, the shorter it is).
5 is placed on the slab catcher 16. After the spliced portion of the roving has been completely wound around the pipe thread 6 (after the above-mentioned time has elapsed), the piston rod 63b of the air cylinder 63
re-immerses the yarn guide 55 into the slab catcher 16.
After lifting from above, the piston rod 60b of the air cylinder 60 is inserted, and the piston rod 63b of the air cylinder 63 protrudes to return the thread guide 55 to the downward waiting position. After completing the series of operations described above, the shin joint machine 2 moves along the spindle 5 again, stops at the next shin joint work position, repeats the above series of operations, and thereafter repeats the above operations to create a ring. °Complete the splicing and replacement of spinning machines.

7 to 9 show different embodiments of the thread guide device. In the moving device 56e of the thread guide device 54e shown in the drawing, reference numeral 70 denotes a longitudinal guide rod installed between the frame members 35be and 35ce of the main body 35e, and a plurality of guide rods are provided.
A movable frame 71 is movably supported by these guide rods 70.

The end of the movable frame 71 is connected via a pin and an elongated hole to a swinging lever 72 that swings back and forth by an air cylinder (not shown), so that it can be moved back and forth by a predetermined amount. 73.
A pair of support rods 74 are rotatably and axially slidably supported by frame members 35ce and 35de, and their rear ends are rotatably connected to the movable frame 71, respectively. A plurality of pairs or one pair of support rods 73 and 74 are provided corresponding to the spindles 5e to be spliced, and are respectively positioned so as to be movable back and forth toward both sides of a position slightly below the Snell wire 15e.

The intermediate portions of ring elements 75, 76 each having a semicircular arc shape are fixed to the front ends of the support rods 73, 74, and when these ring elements 75, 76 are rotated laterally so as to face each other, both ring elements 75 and 76 are connected in a complete ring shape to constitute a thread guide ring 55e, which is illustrated as a thread guide member. The inner diameter of the yarn guide ring 55e is set such that even if the ballooning of the spun yarn becomes large in the state shown in FIGS. 8 and 9, the spun yarn can be rotated below the slab catcher 16e. The size is set to guide you. Reference numerals 78 and 79 denote rotary cylinders which are fitted between the frame members 35ce and 35de so as to rotate integrally with the support rods 73 and 74 via sliding keys, and levers 80 and 81 are respectively fixed thereto. Each lever 80, 81 is operated by an operating bar 82, 83 that is reciprocated by an air cylinder (not shown).
The ring element 75 is connected to the ring element 75 through a pin and an elongated hole and is rotated 90 degrees in opposite directions by one operating bar 82 and 83.
．． 76 can be rotated between an upward position shown in phantom lines in FIG. 9 and a sideways position shown in solid lines.

In the above configuration, in the standby state, the movable frame 71 is located at the rearward end, and the ring elements 75, 76 are housed in the main body 35e in an upward position. After confirming that the amount of winding of the yarn 6e is about 6 minutes or less, we start the splicing work, and at the time of each splicing, the spliced part of the braided yarn is first movable before being spun. The frame 71 is advanced to move the ring elements 75 and 76 to both sides below the Snell wire 15e, and then one of the actuating vanes 82 is moved and one of the support rods 73 is rotated approximately 90 degrees to move the ring elements 75. laterally, the other actuating bar 83 is moved and the other support rod 74 is rotated approximately 90 degrees to bring the ring element 76 sideways, so that the face ring elements 75, 76 are moved into the actuating position and both Both ends overlap each other to form a thread guide ring 5.
Configure 5e. In this state, the spun joint part of the braided yarn is spun out and the ballooning of the spun yarn increases, but the spun yarn is guided by the yarn guide ring 55e slightly below the snell wire 15e, and the slub catcher 16e
It is rotated below. Therefore, the spliced portion of the roving is prevented from being caught by the slab catcher 168 and broken. Ring element 7 of the thread guide ring 55e
5.76 is returned to the original standby position by the above-mentioned reverse operation after the spinning of the spliced portion is completed.

It should be noted that the same or equivalent constituent parts as those of the above embodiment will be denoted by the same reference numerals as those of the corresponding parts with the alphabet e added thereto, and redundant explanation will be omitted.

The present application can be applied to various types of Shino joint machines, for example, in Japanese Patent Application No. 175943/1988, which was previously filed by the applicant of the present application.
As shown in the specification and drawings, the same method can be used to join the roving threads of every other pair of front and rear small bobbins from one end of the creel to the other end, and the threads can also be replaced. It can also be applied to items that are to be joined later.

Effects of the Invention As described above, in the present invention, even if the ballooning of the spun yarn becomes large while the spun joint portion is spun and wound into a pipe yarn, the spun yarn is not ringed by the yarn guide member. Since the thread is guided to the underside of the slab catcher of the spinning machine, it is possible to prevent the spliced part from getting caught in the slab catcher and break the yarn, and the splicing work can be carried out reliably and efficiently.

In addition, there is no need to reduce the rotational speed of the spindle of the ring spinning machine when splicing, and the productivity of the ring spinning machine can be maintained, and the splicing work can be performed even when the bobbin is small. It is effective enough to handle the splicing work on long spinning machines.
