Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a Zj method for automatically inserting spun yarn into yarn being warped.

When applying treatments such as burning, scouring, bleaching, and Norken 1-1 dyeing to warp yarn, which has many yarns lined up in parallel, marks for yarn length, defects, and correction in case of sewing are applied. etc., the spun yarn is inserted into the warp yarn. However, since the number of warp yarns is large, it is not easy to insert the spun yarns. That is, conventionally, for example, the spun yarn was inserted into two pipes,
Either manually tie the ends of each spun thread together to form a loop, or as described in Japanese Patent Publication No. 57-43652, hold the tip of the inserted spun thread with suction air and insert the spun thread into the thread insertion pipe. There was a way to pull it out.

However, with these methods, the operator must constantly insert the spun yarn into the pipe, and when the end of the spun yarn is gripped by air force, there may be discrepancies in the magnitude of the air force and the timing of its action. Failures such as these were occurring.

The present invention utilizes two automatically inserted yarn insertion pipes, sends the yarn from one pipe using an air flow, makes a U-turn, suctions the other pipe, and then pulls out the pipe to discharge the yarn. It relates to a method of inserting yarn, and more specifically, it is a method of inserting two pipes into the opening between the two upper yarns, which is formed by alternately tilting each adjacent yarn of the warp yarn. In the method of inserting yarn, the spun yarn is forced by air flow from one pipe, passes through a semicircular connection part that forms a yarn spouting passage connecting the two pipes, and is transferred to the other pipe that is being rotated 180 degrees during suction. This automatic spun yarn insertion method is characterized in that after feeding, the spun yarn passage in the semicircular connection part is eliminated, the two pipes are pulled out from the warp yarn, and only the spun yarn is inserted into the warp yarn.

The present invention will be explained based on the drawings. As shown in Fig. 1, when each adjacent thread of the running warp yarn is divided into upper and lower parts (AI) and (A, 2) using (1), a space is created in which the pipe (3) can be inserted. Pipe (3) is inserted.

Next, if (AI) and (A2) are swapped up and down, the intersection (+3
) is created, a space for pipe (4) is created, and pipe (4) is created.
) is included.

As shown in Figure 2, the groove of the semicircular connecting part (7), which is fixed close to the ends of the two inserted pipes, changes from a C-shaped groove to a 0-type groove by the lifting action of the lid (8). Thus, the two pipes are connected from one end to the other by an arc-shaped tube, and the lowering action of the lid (8) creates a C-shaped groove and opens the warp side.

Now, when the pipe (3L (4)) approaches the semicircular connection part (7) and stops, the lid (8) will rise and the thread (4) will be inserted into the pipe (4).
5) is blown through the air jet (6) and into the type 0 groove in the semicircular connection (7) from the tip of the pipe. Air suction device (9) attached to the base of the pipe (3)
Due to this action, the spun yarn from the C-shaped groove is sucked into the tip of the pipe (3), passes through the air suction device (9), and activates the spun yarn sensor QO. Then, the lid (8) is lowered and the 0-type groove opens to become a C-type groove.

At the same time, pipes (3) and (4) are pulled out from the warp threads.

At this time, the spun yarn from the semicircular connecting portion (7) is also pulled out, and the spun yarn sandwiching the intersection of the warp yarns is cut to a required length by a cutter @. The cut yarn end of the pipe (3) is blown outside. With this, the thread insertion work is completed.

The above operation is illustrated step by step as shown in FIG. 3. In (a), the warping machine is being warped before the pipe is inserted, and in (b), the warping machine is temporarily stopped by a signal (not shown) sent as necessary, the pipe is inserted, and the air jet (6 ), the spun yarn (5) passes through the tension 0υ to the pipe (4).
Inside, the guide groove of the semicircular connecting part (7) passes through the O-shaped groove, and the air suction device (9) in front of the pipe (3) works to remove the pipe (3). The thread is sucked into the thread, passes through the suction device (9), and the end of the work is confirmed by the thread dispensing sensor 00. (C) shows the C-shaped groove of the semicircular connecting portion (7) opened and the spun yarn being pulled out as the pipes (3) and (4) are pulled out. ) is the pipe (3),
When (4) is completely pulled out, the spun yarn will be in the position shown in the figure. (E) shows the spun yarn being pulled in order to cut or tie it (Figure 2 (B) shows the chevron-shaped pulling mechanism). In (f), the front end of the spun yarn is cut and the warping machine starts to move, and the spun yarn end in the pipe (3) is taken out at point C. During this time, the tension gate 0υ opens and closes to supply the required length of yarn.

is closely related to the above-mentioned operation timing, and Figure 4 is an example of the operation analysis.Here, after the pipe is inserted, air is ejected and sucked into the spun yarn 1 to 2 times in a short period of time. Repeat times. If, in any case, the yarn passing confirmation processor does not work even after ejection and suction are repeated five times, an abnormality signal is generated and the operator is notified using a closure or the like.

As mentioned above, the automatic thread insertion method of the present invention involves several steps of operation, but in reality, the process is almost instantaneous from the start to the end, so the warp production efficiency is high. ,
Moreover, the spun yarn can be inserted reliably. Since these series of operations are automatically controlled, the invention does not require any manual effort to insert the yarn, resulting in a large labor-saving effect.
