Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is a full bobbin roving that is prepared by intermittently moving along a spindle row of a ring spinning machine and preliminarily prepared rovings of a small bobbin being spun at each spindle position. The present invention relates to a ring spinning machine's Shinotsugi, which is designed to be connected to Shinotsu.

2. Description of the Related Art Conventionally, as shown in Japanese Patent Application Laid-Open No. 62-53425, this type of Shino-joint machine uses a small reel bobbin on the front row of the creel when the Shino-maki bobbin becomes a small bobbin. One that intermittently moves toward the end side and joins the rovings of a plurality of small bobbins to the roving of a full bobbin prepared in advance.
As shown in Japanese Patent Publication, when every other two rows of crepe bobbins in the front and rear of the creel become small bobbins, they move intermittently from one end side to the other end side of the machine base, and two front and rear It is known that the roving of No. 1 is spliced onto a full bobbin of roving prepared in advance on a spare rail. The sino-joining work by the sino-jointing machine is started before the tubing yarn reaches about 5 minutes or 6 minutes in order to prevent the tubing thread from becoming full during the operation, and the tubing thread becomes full. It manages to finish all the work before. The Shino-jointing by the Shino-jointing machine is performed by a succeeding method in which the roving thread end of the full bobbin is overlapped on the roving thread end drawn into the draft section, and in this method, the Shino-joint portion is formed by overlapping the roving threads. As it becomes thicker, the spun yarn at the Shino joint becomes thicker,
As a result, the ballooning of spun yarn in the Shino joint part became abnormally large, and the spun yarn was caught in the slab catcher attached to the snell wire of the ring spinning machine,
Thread breakage will occur. Therefore, conventionally, in order to prevent yarn breakage during the above-mentioned jointing, the rotation speed of the spindle of the ring spinning machine is reduced to prevent ballooning of spun yarn from increasing, and spun yarn is less likely to get caught in the slab catcher. In order to achieve this, the actual condition is that the Shino Tsuki machine is designed to perform the Shino Tsuki work when the winding thread of the pipe thread grows to about 5 minutes and the anti-node ring approaches the Snell wire to some extent. Is.

Problem to be Solved by the Invention When the sash joint is performed by the sword splice machine as described above, reducing the rotational speed of the spindle to prevent yarn breakage at the sash splice portion greatly reduces the productivity of the ring spinning machine. There is a problem, and starting the Shino-joint work after the winding diameter of the pipe thread becomes large shortens the time from the start of Shino-joint to the full filling of the pipe thread. As a result, when the number of spindles in the ring spinning machine is large, the yarn will be full before the completion of Shinotsugi, so there is a problem that it cannot support the recent long spinning machines with more than 900 spindles. Therefore, the object of the present invention is to solve the above problems, and to prevent the yarn breakage of the Shino joint portion at the time of Shino joint without lowering the rotation speed of the spindle of the ring spinning machine, and also for a long ring spinning machine. It is to provide a Shinotsuji machine of a spinning machine that can sufficiently deal with the situation.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention provides a ring spinning machine in which a spun yarn is formed on the lower side of a slab catcher even if ballooning of the spun yarn is increased in an operating position. And a moving device that can move the yarn guide member from the standby position to the operating position while the piecing portion of the roving is spun.

Action When the Shino-joining machine performs the Shino-Join work at each spindle position, the Shino-Joint portion of the roving is spun and wound around the tubular yarn, and the yarn guide member is moved from the standby position to the operating position by the moving position. . Ballooning becomes large when the spun portion of the roving is spun, but the spun yarn is guided by the thread guide member so as not to get caught in the slab catcher of the ring spinning machine, so the spun yarn is under the slab catcher. Even if the ballooning of the spun yarn becomes large, it can be prevented from being broken even if the spun yarn becomes large.

Is done. The air cylinders 60 and 63 are operated before the completion of the Shino-joint to put the thread guide finger 55 on the slab catcher 16, and after the Shino-Joint portion has been spun, it is operated in reverse to return the thread guide finger 55 to the original position. It is designed to work in connection with Shinotsugi work.

Next, the operation of the Shinotsugi machine 2 will be described. First, the bobbin suspended on the front row bobbin hanger 25 is a small bobbin 27.
Then, it was confirmed that the winding amount of the tubular yarn 6 was before about 5 to 6 minutes (this winding amount changes depending on the number of the spindles 5, that is, the length of time required for the jointing work of the ring spinning machine). After that, the Shino-joint machine 2 is moved from one end side to the other end side of the machine base 3 along the row of the spindles 5, and the first Shino-joint working position, that is, the Shino-joint head 50, moves the coarse bobbin 27 of the small bobbin 27 to be joined. Positioning is stopped at a position facing the yarn 27a. Next, the Shinotsu device 39
6, the supporting head 41 moves up and down as shown by the arrow in FIG. 6 to remove the full bobbin 33 from the spare bobbin hanger 32 onto the peg 43, and the outlet nozzle 47 is lifted as shown by the arrow so that the suction port is moved to the peg 43. It is located near the outer peripheral surface of the upper full bobbin 33 and at the height of the roving yarn end of the full bobbin 33, and applies a suction force to the suction port. In this state, the full bobbin 33 is rotated to the rewinding side, and the roving yarn end of the full bobbin 33 is sucked and held by the suction nozzle 47. After that, the suction nozzle 47 descends to the original position and the full bobbin 33
Pull down the roving, and guide the end of the roving to the tip of the Shinotsu head 50. Next, the Shinotsu head 50 grips the roving and then swings upward to cut the roving between the suction nozzle 47 into a brush-like shape, and then the Shino succession head 50 advances to remove the roving. The roving yarn 27a introduced into the trumpet 11 is polymerized, and at the same time, the holding of the roving yarn is solved and the roving yarn 27a is held and the roving yarn 27a is cut. As a result, the cut end of the roving yarn of the full bobbin 33 overlaps with the cut end of the roving yarn of the small bobbin 27, is guided from the trumpet 11 to the draft section 10 and is spliced. Be done. After that, the shining lever 51 is moved up and down as shown by the arrow to lift the roving of the full bobbin 33 that has been spliced up and hook it on the mouth-moving guide 20.
To evacuate. In this state, the replacement head of the Shino exchange device 40 moves to remove the small bobbin 27 from the front row bobbin hanger 25 and then returns to the original state, after which the support head 43 (replacement head 52) moves to move the full bobbin 33 to the front row bobbin. Hanger
25, and the replacement head 53 moves to move the small bobbin 27.
To the spare bobbin hanger 32, and then replace both heads.
52,53 returns to the original.

On the other hand, the roving thread of the full bobbin 33 is the roving thread 27a of the small bobbin 27.
Before the roving is spliced to the air cylinder 63 of the thread guiding device 54.
Of the piston rod 63b of the, the support rod 58 is rotated to raise each air cylinder 60 and the thread guide finger 55 to the upper position,
In this state, the piston rod 60b of the air cylinder 60 protrudes, the thread guide finger 59 is positioned above the corresponding slab catcher 16, and then the piston rod 63 of the air cylinder 63 is placed.
With b free, the thread guiding finger 55 is dropped onto the tip of the slab catcher 16 as shown in FIG. Therefore, the thread guiding finger 55 is lifted up integrally with the slab catcher 16 while resting on the slab catcher 16. With the thread guiding finger 55 placed on the slab catcher 16 as described above, the sash splicing portion of the roving spliced by the splicing operation was spun from the draft section 10. Since the sash splicing portion of the roving yarn returns to a length of about 5 to 7 cm and becomes thicker due to the polymerization of two roving yarns, the spun yarn of the sash splicing portion is, for example, 1.5 m when the draft is about 30 times.
It becomes thicker over a length of ~ 2.1 m, and the ballooning of the spun yarn in that portion becomes larger. When the ballooning of the spun yarn is increased in this way, the spun yarn tends to be caught on the tip of the slab catcher 16 as is apparent from FIG. However, in this embodiment, since the thread guiding fingers 55 are placed on the slab catcher 16 as described above, even if the ballooning of the spun yarn becomes large, the spun yarn will be guided by the thread guiding finger as shown in FIG. 5 each time. Slab catcher by the underside of 55
The spun yarn is guided to the lower side of 16 and is not caught by the slab catcher 16, and cutting of the spun yarn by the slab catcher 16 is coarse yarn. It takes about 6 to 8 seconds at the longest to wind the piecing portion of the roving around the tube yarn 6 (it becomes shorter as the rotational speed of the spindle 5 becomes faster), and the thread guide finger 55 is slapped at least for this time. Catcher 16
Put it on top. After the piecing portion of the roving is completely wound around the tube yarn 6 (after the lapse of the time), the air cylinder 63
The piston rod 63b of the slab re-enters and the thread guide finger 55 is lifted from above the slab catcher 16, and then the air cylinder 60
After the piston rod 60b is closed, the piston rod 63b of the air cylinder 63 projects to return the thread guiding finger 55 to the downward standby position. After finishing the above series of work,
The Shino-Join machine 2 moves again along the spindle 5, stops at the next Shino-Joi work position, repeats the above-mentioned series of operations, and thereafter repeats the above-mentioned operations, thereby repeating the Shino-Join of the ring spinning machine.
Complete Shino exchange.
