Hollow spindle s above the spindle member S separated from the nozzle member N
When the compressed air is supplied to the air supply pipe 133, the compressed air is generated in the space formed between the slidable nozzle 129 and the hollow cylindrical body 125. The compressed air sent in presses the ring member 129c protruding from the cylindrical outer wall 129a of the slidable nozzle 129 and moves the slidable nozzle 129 to the left in FIG. 19, so the cylinder attached to the slidable nozzle 129.

Into the space formed between the sliding nozzle 129 and the inner nozzle 130 through the hole 129b formed in the inner nozzle 130, and is discharged through the through hole 128a formed in the cylindrical cover 128. The suction air flow is generated in the through hole 130a. The fins 130b provided on the outer wall of the inner nozzle 130 prevent the air flowing in the space formed between the slidable nozzle 129 and the inner nozzle 130 from becoming a swirling air flow.

When the spun yarn Y is sent out by rotating the roller 108, the spun yarn Y is inserted into the hollow passage 4 of the hollow spindle s by the suction airflow. When the yarn feeding roller 108 of the yarn finger 103 is rotated to feed the spun yarn Y, the reverse rotation roller 70 is driven again to rewind the spun yarn Y from the package b by a required length.

When the spun yarn Y has come out from the tip 2 of the hollow spindle s by a predetermined length necessary for splicing, the rotation of the yarn feed roller 108 of the yarn finger 103 is stopped to stop the spun yarn Y from being sent out, and The supply of the compressed air to the air supply pipe 133 attached to the cylindrical body 125 is stopped, and the compressed air is supplied to the air supply pipe 132. When the rotation of the yarn feed roller 108 of the yarn finger 103 is stopped, the driving of the reverse rotation roller 70 is also stopped. The compressed air supplied to the air supply pipe 132 enters the space 129h formed by the ring member 129d and the edge 125c of the cylindrical body 125, presses the ring member 129d, and moves the sliding nozzle 129 to the right in FIG. ,

Next, the cylinder rod 123a of the cylinder 123 of the air soccer member As is connected to the center of the defibrating tube 134 of the air soccer body x through which the spun yarn Y is passed through the hollow passage 4 and the spun yarn Y is moved from the tip 2 to a predetermined position. The hollow spindle s is retracted until it reaches a arbitrarily set distance from the center of the protruding hollow spindle s. Next, compressed air is sent from the air supply pipe 136 through the recess 135a of the intermediate cylindrical body 135 into the hole 134b formed in the defibration tube 134, so that the twisted direction of the spun yarn Y in the defibration tube 134 is opposite to the twisting direction. A swirling airflow in the direction is generated to untwist the tip of the spun yarn Y extending a predetermined length from the tip 2 of the hollow spindle s to form a spear-shaped tip in which the fibers are defibrated. The air sucker member which stops the supply of the compressed air from the air supply pipe 136 at the stage where the tip ends of the fibers disentangled are formed, retracts the cylinder rod 123a of the cylinder 123, and also retracts the cylinder rod 122a of the linder 122. As is moved to the standby position shown by the chain double-dashed line in FIG.

Next, the cylinder Cs is operated to retract the rod r, and the spindle member S is joined to the nozzle member N as shown in FIG. Also at this time, the yarn feeding roller 108 of the yarn finger 103 is rotated so that the length of the disentangled tip-shaped tip portion protruding from the tip portion of the hollow spindle s can be maintained, and the spun yarn Y is rotated.
And the reverse rotation roller 70 is rotationally driven to rewind the spun yarn Y from the package b as much as necessary. After that, the movable feed roller 109 is separated from the yarn feed roller 108 and the jacket j is moved rightward in FIG.
After extracting the spun yarn Y inserted from 05, the segment gear 93 is rotated clockwise to rotate the gear 94 engaged with the segment gear 93 and move the accelerator wire member v downward. And return it to the standby position, retract the reverse rotation roller 70 to the standby position, and
The shoe lever 61 is rotated clockwise about the fixed shaft 62 to separate the shoe 61a from the shoe 42a of the package positioning lever 42, and the package b is brought into contact with the friction roller d again.

In this state, the hollow spindle s is hammered in at a low speed and rotated, and the electromagnetic clutch Ch of the back roller Rb is connected to start the draft device D to start supplying the sliver L. After the supply of the sliver L is started, the hollow spindle s is fully rotated after a predetermined time, and compressed air is ejected from the air ejection hole 3 of the nozzle n to generate a high-speed swirling air flow to start spinning. Simultaneously with the start of spinning, the nip roller Rn separated from the delivery roller Rd is brought into contact with the delivery roller Rd, and the friction roller d is rotationally driven to start winding the spun yarn Y, whereby the spun yarn Y is disentangled. The newly supplied fibers are connected to the yarn end and spun into a continuous yarn.

Finally, referring to FIGS. 20 to 25, the nozzle member N, the spindle member S, the cylinder Cs and the air sucker member As, which are the main members forming the piecing device P, which constitute the spinning unit Sp, and the transfer arm member Ta The outline of only the operation order will be described. Package b

, The driving of the reverse rotation roller 70, and the like have been described above, and will not be described.

FIG. 20 shows a state in which the spun yarn Y is normally spun with the nozzle member N and the spindle member S constituting the spinning unit Sp joined.

If a yarn break occurs, the cylinder C
s is operated to separate the spindle member S from the nozzle member N and air is blown to the nozzle member N for cleaning (FIG. 21).

Next, the air sucker member As is actuated, and the sliding nozzle 129 of the air sucker member As is arranged above the hollow spindle s of the spindle member S. Thereafter, the transfer arm member Ta holding the spun yarn Y unwound from the package b is attached to the spindle member S.
22. The spun yarn Y gripped and transferred by the transfer arm member Ta by the suction action of the sliding nozzle 129 of the air sucker member As is inserted into the hollow spindle s (FIG. 22).

The spun yarn Y inserted into the hollow spindle s and pulled out by a predetermined length from the tip of the hollow spindle s.
By lowering the air sucker member As,
The tip of the spun yarn Y is defibrated by inserting it into the defibrating tube 134 of the air sucker member As to form a tip shape (FIGS. 23 and 2).
4).

A spun yarn Y disintegrated from the tip of a hollow spindle s as shown in FIG.
By operating the cylinder Cs, the spindle member S in the state in which the nozzles are exposed is joined to the nozzle member N, and the driving of the spinning machine is restarted (FIG. 25).

The operational effects of the above-described embodiments of the present invention will be listed below. The spinning part is divided into a nozzle member and a spindle member so that they can be brought into and out of contact with each other, and a sliver supplied to the spinning part, which has been conventionally difficult, is air-jetted by a member such as an air sucker member or a transfer arm member. It is possible to automate the splicing of a spinning machine that forms spun yarn while spreading the fibers around the outer circumference and twisting the fibers.

Since the spinning section is divided into a nozzle member and a spindle member so as to be freely contactable and detachable, the threading to the hollow spindle becomes easy, and the spinning section such as the nozzle member can be completely and quickly cleaned. .

After the spindle member of the spinning section is separated from the nozzle member, the nozzle member is separated from the front roller of the drafting device by using the ejection of air, and air is jetted to the front roller or the nozzle.
Cleaning around the nozzle including the front roller can be completed completely and quickly. Further, the nozzle casing and the like can be completely cleaned by injecting air from the air injecting holes for twisting the fibers.

When the spun yarn wound in the package is pulled out and moved upward by the suction tube, a guide member having a guide plate or the like is provided, so that handling and control of the spun yarn such as subsequent delivery of the spun yarn are ensured. Can be done quickly.

Since the spun yarn cutting device is arranged on the upper guide plate of the guide member, the cut end of the spun yarn held by the yarn finger of the transfer arm member can be shortened. It can be prevented from contacting or getting tangled with members of the machine.

Since the yarn fingers of the transfer arm member for gripping and feeding the spun yarn are driven and controlled through the accelerator wire member, the spun yarn can be fed or moved accurately and the piecing device can be provided. It can be made compact.

Since the yarn fingers configured to drive and control the pair of thread feed rollers which can be freely moved in and out of contact with each other are controlled by the accelerator wire, the feed amount of the spun yarn inserted into the spindle member can be accurately controlled. The yarn splicing can be performed reliably and quickly.

Since the yarn fingers of the transfer arm member are driven and controlled via the accelerator wire member, the position of the yarn finger can be freely adjusted by transmitting the accelerator wire of the accelerator wire member, and the curvature error of the arm can be adjusted. It becomes easy to absorb.

Since the operation of inserting the spun yarn into the spindle member and the operation of defibrating the spun yarn are performed separately and continuously performed by moving the cylinder rod, each operation can be performed reliably. The splicing operation can be sped up.

Since the fins are provided on the outer wall of the inner nozzle of the air sucker member, it is possible to reliably prevent the air flowing in the space formed between the slidable nozzle and the inner nozzle from becoming a swirling air flow, and thus the defibrated spinning The yarn can be kept in a more natural state, and troubles such as untwisting and cutting of the sucked spun yarn can be prevented.

Since the suction pipe for inserting the spun yarn into the spindle member is slidably formed and is configured to be able to be in contact with the hollow spindle of the spindle member, the insertion of the spun yarn into the hollow spindle is ensured. In addition, the inertia rotation of the hollow spindle can be stopped quickly, and the piecing time can be shortened.

Since the nip roller constituting the spun yarn sending-out member is configured so as to be able to be freely moved toward and away from the delivery roller, it is possible to easily control the spun yarn sending timing when resuming the spinning.

Since the nozzle casing is connected to the suction pipe, harmful floating fibers generated in the nozzle casing during spinning can be removed, and the air ejected from the air ejection holes of the nozzle can be effectively discharged. Therefore, it is possible to prevent the generation of an air flow harmful to the yarn formation.

Since the spun yarn sucked by the suction mouse is transferred to and transferred to the yarn finger that mechanically grips the spun yarn, the spun yarn may be detached during the transfer as compared with the case where the spun yarn is transferred upward by the suction mouse. Without doing
The suction force of the suction mouse can be weakened to save energy.
