Abstract

PURPOSE:To easily perform split weaving, yarn threading, etc. by placing multiple yarn guides at a predetermined interval on a cantilever fixed guide rail and collecting them at the tip section with an air cylinder as required. CONSTITUTION:When multiple blocks such as a tip block 29 and sliding blocks 30, 31, 32 are spread at a predetermined interval, if the sliding block 30 at the base side is pushed to the tip side by a sliding drive shaft 27, the said sliding block 30 at the base side advances to the tip side along a guide rail 23. In this case, the said sliding block 30 at the base side and the second sliding block 31 from the base side is slidably connected with an interval rod 33, thereby the said second sliding block 31 is kept stationary, and when the interval between them is narrowed and they are brought into contact with each other, the second sliding block 31 is pushed by the sliding block 30 at the base side and starts advancing. Subsequently, the second and third sliding blocks 31, 32 likewise advance in sequence, and yarn guides 37 are collected near the tip of the guide rail 23.

Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a multi-filament guiding device for narrowing or widening the interval between a plurality of threads running in parallel as necessary. In a multi-filament winder used in the spinning process of synthetic fibers, there is a splitting device that widens the spacing between multiple threads running in parallel at narrow intervals and guides them to a traverse guide, and a fiber suction device that guides the threads to a traverse guide. A device or the like is used to separate a plurality of threads and thread them onto an empty bobbin.

(Prior Art) As shown in FIG. 8, as a conventional multi-filament winder, four threads are spun from an upper spinning nozzle (not shown).
The main synthetic fiber multifilament yarn (hereinafter referred to as yarn) Y is taken up by a roller 1, a guide roller 2, and a fiber splitting device 3.
It is known that yarn is wound onto a bobbin 6 via a yarn guide 4 and a traverse guide 5. In addition, C
7 is a traverse cam box, and 8 is a bobbin support shaft. The above-mentioned yarn guide 4 for splitting is
The splitting yarn guide 41 is fixed at predetermined intervals to sliding rods 9a that are slidably fitted into a cylindrical support guide 9; By pulling it out (to the left in the figure), the yarn Y can be easily hung on the yarn guide 4 located at the back (on the side of the support guide 9).

In addition, a thread hook for winding the plurality of yarns Y, which are sucked into the lower air sucker 10, around the bobbin 6 is provided between the air sucker 10 and the bobbin support shaft 8 as a device to facilitate the work. A cylindrical support 1 parallel to the bobbin support shaft 8
1 is provided, and a plurality of yarn guides 13 are attached to the operating rod 12 which is slidably fitted to the support 11, and the operation rod 12 is pulled out to the front and the yarn guides 13 are attached to the operating rod 12 which is slidably fitted to the support body 11. 13 toward the front, and in this state, the threader inserts the yarn Y into the yarn guide 13. Then, by pushing the operating rod 12, the threader widens the gap between the yarn guides 13, and then the threader inserts the yarn Y into the yarn guide 13. It is known that the thread Y is pressed against the bobbin 6 by rotating in the direction of the arrow P, and at the same time, the thread Y is cut between the bobbin 6 and the air sucker 10 by the tension. Showa 60-56774
(see publication).

(Problems to be Solved by the Invention) A large number of the above multi-filament winders are arranged along a passage, and the bobbin support shaft 8 is oriented at right angles to the passage. Moreover, in recent winders, the length of the bobbin support shaft 8 is 120 to 140 cm, which is much longer than the conventional 60 to 80 cm, due to multi-filament winding and large packaging.
m, and the fiber splitting and threading operations are becoming increasingly difficult, so the need for the above-mentioned fiber splitting equipment and threading equipment is increasing.

However, in the conventional fiber splitting device 3, the sliding rod 9a to which the fiber splitting yarn guide 4 is fixed is placed in the front.

That is, since it is pulled out to the passage side in front of the machine, there is a problem in that other workers and transport vehicles cannot pass through the passage while threading the separating yarn guide 4 is being carried out. Furthermore, since the thread hooking device described in JP-A No. 60-56774 is one that pulls out the operating rod 12 toward the front, similar to the above-mentioned fiber splitting device 3, it is difficult for other workers or transport vehicles to pass by. There was a problem of interfering with

The present invention is capable of narrowing or widening the interval between a plurality of threads running in parallel as necessary, like the splitting device and thread hooking device of the multi-filament winder. Moreover, it is an object of the present invention to provide a multi-filament guiding device that does not protrude to the passage side during its operation.

(Means for solving the problem) A linear guide rail 23 is provided in a cantilevered manner, and a tip block 29 is fixed to the tip of the guide rail 23, and at least one sliding block 30. 31

and sliding blocks 30, 31, 32, etc., two at a time, and stoppers 33a, 34a, 35 for preventing the other from moving forward and backward with respect to one of them within a predetermined interval.
a, connect the sliding drive shaft 27 to the sliding block 30 at the proximal end, and attach the yarn guide 37 to the sliding block 30, 31, 32 mentioned above. .

(Function) Tip block 29 and sliding block 30.31.32
When a plurality of blocks such as the above are spread out at a predetermined interval, when the sliding block 30 on the base side is pushed toward the tip side with the sliding drive shaft 27, the sliding block 30 on the base side moves along the guide rail 23. and move forward toward the tip. At this time, since the sliding block 30 on the base side and the second sliding block 31 from the base side are slidably connected by the spacing rod 33, the second sliding block 31 does not stand still. °Continue, when the distance between the two becomes narrower and they touch, 2
The th sliding block 31 is pushed by the sliding block 30 on the base side and starts moving forward. Similarly, the second and third
The sliding blocks 31, 32 move forward in the order of the slide blocks 31, 32, and when the slide block 32 closest to the tip comes into contact with the tip block 29 fixed to the tip, the above drive is stopped and the slide blocks 30, 32 move forward. Yarn guides 37 fixed to 31 and 32 are gathered near the tip of the guide rail 23.

On the other hand, a sliding block 30.
31 and 32 are gathered, when the sliding block 30 on the base side is pulled by the drive shaft 27 and retreats toward the fixed part, the sliding block 30 on the base side and the second sliding block 31 from the base side Since they are slidably connected by the spacing rod 33, the second sliding block 31 remains stationary until the distance between the two reaches a predetermined distance determined by the length of the spacing rod 33. When the spacing is reached, the second sliding plot 31 begins to retreat under the action of the stopper 33a of the spacing rod 33. From the base side, 2
The sliding blocks 31 and 32 are moved back in the order of 3rd and 3rd.
When the distance between the last sliding block 32 and the tip block 29 reaches a predetermined distance, the driving is stopped and the plurality of yarn guides 37 are fixed at a predetermined distance.
