Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reeling method for preventing the occurrence of an abnormal fineness, which is called a fineness far from the target fineness, which occurs when the cocoon yarn is reeled from the cocoon to the target fineness.

[0002]

2. Description of the Related Art The reeling of a cocoon yarn from a cocoon to a predetermined fineness is most often carried out by a constant fineness reeling machine shown in FIG. The reeling by this is performed as follows.

A plurality of cocoons 2 reeled in the reel tank 1.
Is passed through the rotary binding device 3 and then focused by the binding device 4 to the kennel 5
After passing through the intermittent drum 6 through the fineness sensor 7, the drum 8,
After passing through 9 and the interlacing 10, the small frame 11 is wound and the raw silk S is prepared. The cocooning machine 12 is circulated to the front of the reeling tank 1, and when the fineness becomes fine in the cocooning machine 12 due to a failure in the reeling process, a standby cocoon for storing new cocoons is stored. There is. When it is detected by the constant fineness sensor 7 that the reeling fineness has decreased, the binding drive device 13 is activated and the binding rod 14 is activated.
Is for taking out the cord cocoon 2 discharged from the cocoon feeder 12, guiding the cord to the rotary binding device 3, and performing the binding.

The above-mentioned constant fineness sensor 7 operates in cooperation with the retrieval device 15. The retrieval device 15 intermittently retrieves the fineness of the running raw silk S which is being prepared. Figure 3
The operating state is shown in C of FIG.

The search device 15 comprises an adder wheel 16, an L-shaped adder lever 17, a cam adder lever 18, and a search metal fitting 19. The L-shaped drive lever 17 is swingably supported by a support member 21 with a shaft 20 as a fulcrum, and one end of the lever 17 and one end of a cam addition motion lever 18 are pivotally stopped by a shaft 22 to make a cam addition motion. The cam 23 of the lever 18 is positioned so as to contact a cam follower 24 provided on one side of the driven wheel 16. In addition, the cam addition lever 18
At the end opposite to the shaft 22 of the operating rod 25 connected to the attachment drive unit 12.
Is supported by a shaft 28 so as to hang down. The actuating rod 25 mechanically actuates the binding drive device 13 when it is pulled up by the cam adding motion lever 18, but at that time,
The force by which 18 pivots counterclockwise around shaft 22 and pulls up operating rod 25 is greater than the force by which cam-applying lever 18 pivots around shaft 28 clockwise. The end portion of the L-shaped cam lever 17 and the search metal fitting 19 are connected by a connecting rod 26. The search metal fitting 19 is pivotally supported 27 at its central portion, is it? It has a letter shape and supports the intermittent drum 6 at the lower end, and a cutout 30 is provided at the outer peripheral edge of the bent portion 29 at the upper end. A fixed-fineness sensor 7 is pivotally supported so as to be able to swivel in a manner substantially parallel to the search metal fitting 19. The constant-definition sensor 7 has two discs 31 supported in parallel with a spacer (not shown) between them with a small gap therebetween, and a weight limiting rod 33 having a pin 32 protruding from the tip side. To provide.
The raw silk S for which the fineness is to be searched is intermittently inserted between the slits of the constant fineness sensor 7 by the swinging action of the intermittent handwheel 6 described below while passing between the intermittent handwheel 6 and the handwheel 8. At that time, the fineness is searched.

The search operation is performed as follows. The motor 16 is constantly rotating in the direction of arrow 12. Each time the driven wheel 16 rotates, the cam follower 24 moves the cam 23
3 and the cam 23 is lifted up, but the cam addition drive lever 18 and the L-shaped drive lever 17 are integrally pivoted by the shaft 22. Therefore, the L-shaped drive lever 17 is supported by the shaft 20 as a fulcrum. A rotates in the clockwise direction at A, and the probe 19 is rotated in the clockwise direction around the shaft 27 via the connecting rod 26.

In the above, if the fineness of the yarn S is the target fiber, the disc forming the slit of the yarn S and the constant fineness sensor 7
Due to the friction with 31, the constant-fineness sensor 7 moves as the yarn S progresses.
In A, the pin 32 of the eccentric weight limiting rod 33 is rotated in the counterclockwise direction and is raised, and the notch 30 of the bent portion 29 of the probe 19 is also engaged by rotating the probe 19 in the clockwise direction. No
The search metal fitting 19 can pivot to the maximum clockwise direction. Therefore, the cam-adding lever 18 pivots the shaft 22 in the clockwise direction so that the hanging end of the actuating rod 25 serves as a fulcrum, and the actuating rod 25 does not move up to operate the binding drive device 12. There is no.

On the contrary, when the fineness of the yarn S is lowered, the constant fineness sensor 7 overcomes the frictional resistance with the yarn S traveling upward and moves in the clockwise direction by the weight of the eccentric weight limiting rod 33. As it swivels, the pin 32 is bent at the bent portion 29 of the search metal fitting 19.
When the probe metal 19 is swung in the clockwise direction by the rotation of the driving wheel 16 as described above, the pin 32 engages with the notch 30 and the probe metal 19 further pivots. It becomes impossible to move. However, since the driven wheel 16 continues to rotate and the cam follower 24 pushes up the cam 23, the cam-equipped lever 18 pivots counterclockwise around the shaft 22 and raises the operating rod 25. The raising of the operating rod 25 actuates the binding drive device 13 to rotate the binding rod 14 to bind the cocoon thread from the cocoon machine 12 to the rotary binding device.

As described above, in the constant-fineness reeling machine, the frictional resistance of the traveling raw yarn S is large or small (the deformation resistance of the traveling yarn S due to the slit formed by the disc 31 constituting the constant-fineness sensor).
When the fineness becomes smaller than a certain limit value while searching intermittently, the production operation of replenishing one cocoon grain is continuously performed.

However, such a regular production operation is not always performed continuously, and an abnormal situation occurs in reality, so that the thickness is significantly larger or thinner than the fineness standard of the prepared raw silk. A fluctuating situation occurs, which results in an abnormality called so-called fly-fineness yarn mixing, resulting in deterioration of raw silk quality.

The factors causing this abnormal fineness and the actual conditions of thick and thin abnormalities are as follows. 1. The running yarn path is out of the slit type fineness sensor. … Thick 2. Slits such as sericin are clogged in the slits of the slit type constant density sensor. … Thick and thin 3. The slit of the slit type fineness sensor is clogged with thread waste. … Thick and thin 4. Slit type fineness sensor tilts due to shock or insertion error… Thin 5. Non-operation and abnormal operation due to mechanical trouble of the rod system… Fine 6. Mechanical trouble of retrieval device Abnormality of search due to ... Thick and thin 7. Insufficient cocoon in cocoon machine and no cocoon waiting at unloading slot ... Thin 8. Unable to remove due to mechanical trouble at unloading slot in cocooning machine ... Occurrence (continuous attachment) ...

As a phenomenon of such an abnormal occurrence, the cocoon machine 12
Aside from the method of moving, the reeling system and the cocooning machine have a 1: 1 opposing relationship with each other, and all of 1 to 9 are characterized in that they continuously generate the attachment request signal. is there. In the system in which the cocoon machine 12 moves, 7 and 8 have abnormalities. Even if there is one abnormal cocoon machine, if the next cocoon machine is normal, there will be a time delay but the abnormality will be corrected and the abnormal fineness will be Modified and restored. However, if the cocoon lacking cocoon machine shown in 7.
Most of the shortage of cocoons replenished to the cocoon machine from the papermaking section takes a long time to restore the standby cocoon amount, resulting in continuous fineness. From such a fact, it was found that most of the fibers with the degree of fineness generated had the continuous attachment request signal. The other remaining phenomenon is that as a result of the other phenomenon of 5 and 6, the result is that no attachment is made. The reeling is continued without performing the search movement or the binding movement, which rarely occurs phenomenologically.

That is, when classifying the occurrence of the degree of fineness, firstly, most of the time, a continuous stitching request or a continuous stitching movement is performed, and secondly, the stitching is not performed for a long time and a fine stitching is performed. It was found that the degree of fineness is rarely generated.

[0014]

In order to prevent such an abnormal situation, the production worker is forced to carry out a constant visual correction at all times to find out the abnormal condition and immediately perform a correction operation. Continuous visual observation is mainly performed by comparing the number of cocoon particles in the reeling tank, but not only is it inaccurate, but continuous monitoring is virtually impossible, resulting in a time delay and abnormal fineness of raw silk. As a result, the work of removing the roll back is also required, which results in an increase in the amount of raw silk waste. Thus, the constant monitoring work for detecting anomalies that occur occasionally is not only unproductive, but also results in an increase in labor cost and an increase in production and processing cost, and a decrease in raw silk quality and a decrease in production efficiency. Etc. will be lost. Such an abnormality is the same not only in the constant fineness reeled yarn but also in the fixed grain reeled yarn.

In view of the above points, it is an object of the present invention to provide a reeling method for preventing the occurrence of abnormal fineness, in which the desired fineness is developed on both sides of thin and thick, without any manual operation.

[0016]

[Means for Solving the Problems] In a reeling method for intermittently searching the fineness of a reeled yarn and detecting a decrease in the fineness, a binding request signal is issued to perform a binding operation, after the binding operation. When the number of times of request for sending the binding or the number of times the binding operation reaches a predetermined number without interruption without the recovery of the fineness of the reeling, the reeling is stopped as an abnormal fineness phenomenon occurs.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the device of the present invention will be described below with reference to the drawings.

In the device of the present invention, portions having the same structure as the conventional example will be described with the same reference numerals as the conventional example, and points different from the conventional example will be described with new reference numerals.

L-shaped drive lever 17 and cam addition drive lever
A claw wheel 41 is provided below the 18. The ratchet wheel 41 is supported by the shaft 42 in a free state, and a winding spring 43 is stretched between the shaft 42 and the ratchet wheel 41 to increase the elastic force when the ratchet wheel 41 rotates in the counterclockwise direction on the drawing. It is biased to rotate in the direction of the clock hand.
A ratchet wheel 44 is provided on the side surface of the ratchet wheel 41, and a stopper 45 is provided at a position where the ratchet wheel 41 contacts the ratchet wheel pin 44 when the ratchet wheel 41 rotates in the clockwise direction. The support shaft 20 of the L-shaped drive lever 17 supports a spring hook 46 bent in an L-shape.
One end of the spring hook 46 is locked to the upper arm of the L-shaped drive lever 17, and the hook 47 formed at the other end is connected to the ratchet wheel 41.
To prevent rotation by the winding spring 43. A ratchet wheel rotation arm 49 having a hook 48 at the lower end is hung on the shaft 20.

Now, assume that the reeling operation is performed in the state shown in FIG. The cam follower 24 comes into contact with the cam 23 of the cam adding motion lever 18 by one rotation of the driven wheel 16 in the direction of the arrow, and tries to move up the cam 23. The cam addition lever 18 has a shaft 22
Since the turning in the clockwise direction around the shaft 28 can be performed with less force than the turning in the counterclockwise direction around the center, the cam addition lever 18 is integrated with the L-shaped lever 17 at the shaft 22. Therefore, the L-shaped drive lever 17 pivots around the shaft 20 in the clockwise direction by the upward movement of the cam addition drive lever 18,
Through the connecting rod 26, the search metal fitting 19 is swung about the shaft 27. The intermittent drum 6 supported on the lower end of the search metal fitting 19 by the above-mentioned swinging motion is shown in FIG.
It swings to the left and right around 27, and this movement causes the raw silk S guided by the intermittent drum 6 to be taken in and out of the slit of the constant-fineness sensor 7. That is, the raw silk S from the kennel 5 to the drum 8 runs while being in contact with the intermittent drum 6 while being refracted.
The raw silk S traveling between the intermittent drum 6 and the drum 8 is released from the above refraction by swinging in the left direction at, and enters the slit of the constant fineness sensor 7, and the raw silk S and the constant fineness detector are detected. When a predetermined fineness abnormality occurs due to friction between the circular disc 31 and the circular disc 31, the circular disc 31, that is, the constant fineness sensor 7 pivots counterclockwise in FIGS. 1A and 1B, Raise the position of pin 32. However, when the raw silk S does not reach the predetermined fineness, the friction is small and the constant fineness sensor 7 cannot be swung.

The oscillation of the intermittent drum 6 is the same as that of the intermittent drum 6
It is performed once per rotation. As the handwheel 6 swings to the left in FIG. 1, the bent portion 29 of the probe 19 pivots around the shaft 27 in the clockwise direction, but the pin 32 of the fineness sensor 7 rises as described above. Therefore, there is no engagement between the notch 30 and the pin 32, and the swing of the probe 19 in the clockwise direction is not blocked.

Therefore, the turning angle of the L-shaped driving lever 17 is large, and the spring hook 46 supported by the shaft 20 and locked by the L-shaped driving lever 17 also turns about the shaft 20 at the same turning angle. The hook 47 at its tip is released from the engagement with the ratchet wheel 41, and the ratchet wheel 41 is rotated to the position where the ratchet wheel pin 44 hits the stopper 45 by the repulsive force of the winding spring 43 provided on the ratchet wheel 41. . That is, when the fineness search operation is performed once and the fineness of the target fineness is detected by the turning reciprocating motion of the metal fitting 19, the ratchet wheel 41 is returned to the origin of zero stitching.

On the other hand, when the fineness of the running yarn S becomes smaller than the fineness, the constant fineness sensor 7 turns clockwise as shown in FIG. 1C, and the pin 32 of the eccentric weight limiting rod 33 is rotated. Is in contact with the upper edge of the bent portion 29 of the search metal fitting 19, and at that time when the search metal fitting 19 is pushed by the connecting rod 26 and pivots in the clockwise direction, the pin 32 enters the notch 30 of the search metal fitting 19. , Connecting rod
The forward movement of 26 and the swinging of the L-shaped drive lever 17 in the clockwise direction are prevented. Therefore, since the turning angle of the L-shaped drive lever 17 about the shaft 20 is small, the spring hook also remains locked to the ratchet wheel. However, as described above, although the L-shaped drive lever 17 stops the turning motion,
Since 16 continues to rotate as it is, the cam follower 24 continues to lift the cam addition motion lever 18 via the cam 23. At this time, since the cam adding motion lever 18 cannot ascend on the shaft 22 side as described above, it turns around the shaft 22 in the counterclockwise direction and pulls up the operating rod 25.
Actuate the attachment rod 14 and make one attachment. The ratchet wheel rotating arm 49 also rises as the actuating rod 25 rises due to the counterclockwise rotation of the cam adding lever 18 and the hook 48 provided at the lower end of the ratchet wheel arm 49 causes the ratchet wheel 41 to move counterclockwise by one tooth. Rotate in the needle direction.

When the fineness of the raw silk S is restored to normal by the above-mentioned binding action, the L-shaped actuating lever by the contact of the next cam follower 24 and the cam 23 by the next rotation of the driving wheel 16 is performed.
At the time of searching the fineness of the search metal fitting 19 via 17, as described above, the ratchet wheel 41 is disengaged from the hook 47 on the assumption that the normal fineness is held, and the ratchet wheel pin 44 is released by the elastic force of the winding spring 43. Has returned to the 0 position where it contacts the stopper 45.

When the fineness is reduced by the above-mentioned binding action, the binding is performed at the time of the next fineness retrieval after the motor wheel 16 makes one continuous rotation. At this time, the ratchet wheel 41 is further fed by one tooth by the descending and ascending movements of the ratchet wheel rotating arm 49. Then, the state of fineness fineness or less continues in succession, and the nail wheel pin 44 is rotated to the position of the switch 50 at the time when the nail wheel 41 is intermittently turned by that amount of time, the stitches are continuously made for a predetermined number of times. And then
The small frame stop device (not shown) is operated via the switch 50 to stop the winding of the small frame 11.

As described above, according to the method of the present invention, the fineness is not recovered despite the fineness signal, and the abnormal signal is issued only when the fineness signal continues for a predetermined number of times or more. However, the number of times can be arbitrarily set by changing the position where the ratchet pin 44 and the switch 50 face each other. If the fineness signal is not generated next even if the fineness signal is generated two or three times in succession, the ratchet wheel instantly moves to the position where the ratchet pin 44 hits the stopper 45 by the winding spring 43.
As described above, the point 41 was reversed and returned to the zero point.

[0027]

As described above in detail, according to the method of the present invention, when the fineness of the reeled yarn is intermittently searched and a decrease in the fineness is detected, a binding request signal is issued to carry out the binding operation. In the method, when the number of times the request signal is transmitted or the number of times the operation operation reaches a predetermined number continuously without the recovery of the fineness of the reeling after the operation operation, or when the request signal is received within a predetermined time. When there is none, the yarn winding is stopped as the occurrence of an abnormal fineness phenomenon, so that it is possible to eliminate the occurrence of large and fine flying fineness, and it is possible to eliminate the constant monitoring.
