Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a stringing method, and particularly in the case of dupioni reeling and direct reeling, the present invention relates to a method for splicing new cocoon strings to strings that have been collected in a threading tube and are being rolled up. When stringing, a stringing device such as a rope broom for stringing new cocoon strings attaches new cocoons to grain-bearing strings, and when separating them from the grain-bearing threads, the strings are lifted up. The purpose of this invention is to prevent the occurrence of a situation in which the cord of another cocoon with grains is entangled and the cord is torn off from the grain-bearing cocoon.

When dupioni reeling or direct reeling is performed, the number of grains is several times or several tens of times larger than in general automatic reeling, and the diameter of the area where the grained cocoons are located is also larger. To attach a cord to a cocoon with grains, a cord broom at the tip of a swinging arm suspended from a support arm is moved in a circular trajectory around the cone formed by the grain-bearing cocoon and its cord thread. The rope was rotated and swung periodically toward grain attachment, and the new cocoon thread that had been taken out with the cording broom was attached. Because the trajectory when approaching the thread is the same as the trajectory when leaving the thread with grains attached after being attached,
There have also been cases where the string that has already been tied and is being reeled is torn off from the grain attachment and removed.

Therefore, in the method of the present invention, when attaching a new cocoon to the grain-bearing yarn during reeling using a cording broom, the trajectory of the cording broom when it approaches the grain-bearing yarn and the trajectory when it leaves the grain-bearing yarn are determined. The trajectory was changed so that after the stringing, the stringing broom moves away from the string of the grained cocoon, unlike the trajectory before stringing, and then swings downward and returns to its original position.

Next, an example of an apparatus for carrying out the method of the present invention will be explained with reference to the drawings.

Reference numeral 1 denotes a silk reeling tank, which has a circular planar shape, and a pupae discharge tank 2, which has a rectangular planar shape and is integrally continuous with the silk reeling tank 1 at the bottom of the tank, is provided on the side of the reeling tank. The reeling tank 1 is

4 and a rotary disk 25 are supported on the frame 3. The bevel gear 24 is connected to a drive shaft 26 connected to a driving part (not shown).
It meshes with a bevel gear 27 provided at one end, and rotates the rotary disk 25 as the driving part rotates. Turntable 2
5, the support arms 28 branch out radially into a plurality of support arms 28, and a cord member 30 is suspended from the tip thereof. The cord member 30 has a plurality of cord brooms 33 attached downward to a cord broom base 32 provided at the lower end of the cord rod 31, and an elongated hole extending in the axial direction is provided in the upper base plate 34 of the cord rod 31. 35 and a concave portion 36 continuing to the end of the elongated hole 35, and a pin 37 is provided near the base plate 34, so that the cord rod 31 can swing freely with respect to the support arm 28 by the pin 38. It is hanging down.

A guide bar 42 of the cord member 30 is supported by a support rod 40 and a support rod 41 fixed to the peripheral wall 15 of the reeling tank 1. The guide bar 42 is located at the upper part of the reeling tank 1, and is used to lift up the cord rod 31 hanging down in the reeling tank 1, and to cause the cord broom 33 at the tip of the cord rod 31 to perform a splicing operation. It is provided in an arc shape over about half the circumference of the reeling tank 1, and the radius of the arc is smaller than the length of the support arm 28.

A cord member pull-back bar 43 for pulling back the cord member is provided below the guide bar 42 over about a quarter of the circumference and bent so as to gradually move away from the axis of the hollow shaft 23.

The thread threading tube 50 is inserted into the hollow shaft 23 of the cord member 20. The threading tube 50 has a swing arm 52 that is swingably supported by a support arm 51 fixed to the frame 3.
It is rotatably suspended from the tip of the shaft by a bearing 53. The other end of the swinging arm 52 is connected to a pulley 5 that is integrated with the motor shaft of a motor 54 supported by the frame 3.
The motor 5 is
4 rotates, the thread passing tube 50 vibrates up and down. A pulley 57 is provided at the upper end of the threading tube 50, and a belt 58 is stretched between the pulley 57 and the pulley 55. As a result, the thread threading tube 50 rotates while vibrating vertically.

Next, the attachment method will be explained.

In the reeling tank 1, the cocoons 70 that have been drawn out are concentrated in the thread passing tube 50, forming a cone with the cocoon grains as the base and the cord yarn as the hypotenuse, and the cocoons 70 are assembled into a winding frame (not shown). It has been raised to . and,
As the support arm 28 rotates, the cording member 30 approaches the cone with the cording broom 33 entwined with the new cocoon's cord 72, and wraps the new cocoon's cord 72 pulled out by the cording broom 33. The cord is attached to the thread 71 of the conical body, entwined with it, and pulled up towards the thread threading tube 50 to perform the threading. The details are as follows.

The strapping device 20 transmits power from a drive source (not shown) to a drive shaft 26, bevel gears 27, 24, and a hollow shaft 2.
3. The support arm 28 is rotated by the rotary disk 25.

In FIG. 2, when the cord member 30 is in position A, it hangs vertically from the cord rod 31 to the tip of the support arm 28 (FIG. 4), and at this time, the cord broom 33 is at the tip. is immersed in the reeling bath and brought into contact with new cocoons or cocoons that have not been coed out among the new cocoons or fallen cocoons floating on the surface of the reeling bath. As the support arm 28 rotates, the rope broom 32 moves in an arcuate trajectory centered on the hollow shaft 23 until it approaches the position B in FIG.
Near position B in the figure, the cable rod 31 is connected to the guide bar 42.
come into contact with. As the guide bar 42 approaches the C position from the B position, the distance from the hollow shaft 23 gradually decreases, so that the cord rod 31 gradually becomes closer to the cord broom 33.
is taken out of the reeling bath, the tip is raised as shown by lines a to b in FIG. 4, and the cord broom 33 approaches the grained cocoon 70 being reeled. Then, when leaving the reeling bath, since the cord of the new cocoon is entangled in the rope broom 33, the cord of the new cocoon is pulled out and the cord 7 of the cocoon with grains 70 is removed.
By approaching the above-mentioned cord broom and moving in an arc, the cord thread is entangled obliquely on the surface of the cone formed by the cord broom. Then, at position B in FIG. 2, the cord broom 33 rises the most and is positioned above the lower end of the thread threading tube 50, thus completing the cord splicing. The attached cord is wound up together with the cord 71 of the grained cocoon 70 through the thread threading tube 50.

Next, when the cord rod 31 passes through the position C in FIG. (from b to c in Figure 4).
Then, the cord member 30 is stopped in a state where the pin 38 that pivotally supports the cord rod 31 is fitted into the recess 36 at the end of the elongated hole 35. (Fig. 4) In this state, when the cord member 30 is rotated and passes the D position and comes near the A position, the guide bar 42 disappears, so the cord rod 31 that was supported by the guide bar 42 until then is removed from the cord. Turn the broom 33 in the direction of dropping (Fig. 4) and immerse the cord broom 33 into the reeling bath, but the cord rod 31
The pin 38 that pivots the rope rod 31 at the start of turning
is engaged with the concave portion 36 of the upper base plate 34 of the cord rod 31, so the cord rod 31 turns around the concave portion 36, and the radius of rotation of the cord broom 33 becomes small. That is, it passes through a course from c to d shown by the dashed line in Fig. 4 and is vertically positioned (Fig. 4), at which time the pin 38 comes out of the concave portion 36, and the tip of the cord broom is positioned vertically as shown in Fig. 4 d to a. The rope broom 33 is immersed in the reeling bath as shown in FIG. 4. In that state, the second
Turn from position A to position B again in the figure, raise the cord broom 33 as before, and transfer the cord entangled with the cord broom 33 from position A to position B to the cord of the cocoon with grains. Accompany it.

During the cording operation by the cording member 30, the swinging arm 52 swings due to the rotation of the motor 54, swinging the threading tube 50 up and down, and also moving the threading tube 50 through the belt 58. The thread rotates to prevent pupa, etc. from clogging the thread tube, and also to twist the thread.

In addition, the pump 11 is activated to suck the reeling water from the pupa collection tank 13, flow it into the reeling tank 1 from the outlet 8 of the cap 9, and circulate it.

As described in detail above, in the present invention, since the cording broom that performs the strapping operation has a swinging trajectory during the strapping and a swinging trajectory after the strapping is different,
The cording broom that returns to its original position after stringing may re-hook the string attached to the grain-bearing cocoon and cause it to separate from the grain-bearing cocoon, or the grain-bearing cocoon is being rolled up during reeling. It is possible to prevent occurrences such as cutting the thread and causing thread failure.
