In FIG. 1, L denotes a sliver supplied to a draft device D via a sliver guide T. The draft device D includes a back roller Rb, a third roller Rt, a second roller Rs having an apron, and a front roller R.
The sliver L drafted by the draft device D is supplied to a spinning unit Sp including a nozzle member N and a spindle member S, and is formed into a spun yarn Y in the spinning unit Sp. The spindle member S is held by a support member h at the tip of a rod r of the cylinder Cs, and is configured to be separable from the nozzle member N as described later.

FIG. 2 shows the nozzle member N shown in FIG.
FIG. 2 is an enlarged partial cross-sectional view of a hollow spindle s of a nozzle n and a spindle member S of FIG.

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 first supplied to the space formed between the sliding nozzle 129 and the hollow cylindrical body 125. The compressed air is sent in and presses a ring member 129c protruding from a cylindrical outer wall 129a of the sliding nozzle 129 to move the sliding nozzle 129 leftward in FIG. The cylindrical cover 131 is protruded from the hollow cylindrical body 125, and the distal end portion 2 of the hollow spindle s is fitted into the through hole 131a of the cylindrical cover 131, and the free rotation of the hollow spindle s can be stopped by this fitting. .

The compressed air supplied from the air supply pipe 133 causes the cylindrical cover 131 to protrude from the hollow cylindrical body 125, and the cylindrical side wall 129 a of the sliding 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 are for preventing the air flowing in the space formed between the sliding nozzle 129 and the inner nozzle 130 from becoming a swirling air flow. When the suction airflow becomes a swirling airflow, the spun yarn Y that is defibrated by the defibration tube 134 in the next stage after the introduction of the yarn cannot be kept in a more natural state, and is inserted into the threading hole 130a.

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 feed roller 108 of the yarn finger 103 is rotated to feed the spun yarn Y, the reverse rotation roller 70 is driven again, and the spun yarn Y is rewound 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 a 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 rightward in FIG. ,
Cylindrical cover 13 attached to sliding nozzle 129

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 to the hole 134b formed in the defibrated tube 134 through the concave portion 135a of the intermediate cylindrical body 135, so that the direction of twist of the spun yarn Y in the defibrated tube 134 is opposite. In this way, a swirling airflow is generated in the direction, and the tip of the spun yarn Y projecting a predetermined length from the tip 2 of the hollow spindle s is untwisted to form a spike-shaped tip where the fibers are unwound. At the stage where the spike-shaped distal end portion where the fibers are defibrated is formed, the supply of the compressed air from the air supply pipe 136 is stopped, the cylinder rod 123a of the cylinder 123 is retracted, and the cylinder rod 122a of the cylinder 122 is retracted, so that the air sucker member is retracted. As is moved to the standby position indicated by the two-dot chain 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. At this time, the spun yarn Y is rotated by rotating the yarn feed roller 108 of the yarn finger 103 so that the defibrated tip portion protruding a predetermined length from the front end of the hollow spindle s can maintain the length.
And the reverse rotation roller 70 is rotationally driven to rewind the spun yarn Y from the package b as necessary. Thereafter, 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 to move the accelerator wire member v downward. To return to the standby position and retract the reverse rotation roller 70 to the standby position.
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 again brought into contact with the friction roller d.

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, after a predetermined time, the hollow spindle s is fully rotated, and compressed air is ejected from the air injection hole 3 of the nozzle n to generate a high-speed swirling airflow, thereby starting spinning. Simultaneously with the start of the spinning, the nip roller Rn, which has been separated from the delivery roller Rd, is brought into contact with the delivery roller Rd, and the friction roller d is driven to rotate to start winding the spun yarn Y. The newly supplied fiber is connected to the yarn end and spun as 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. In addition, package b
Of the spun yarn Y entangled in the yarn, and the spun yarn Y rewound
, 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 to clean the nozzle member N by blowing air (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 moved to the spindle member S.
And the spun yarn Y gripped and sent out 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 from the tip of the hollow spindle s by a predetermined length
By lowering the air soccer member As,
The tip of the spun yarn Y which is inserted into the defibration tube 134 of the air soccer member As is defibrated into a tip-like 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 operation and effect of the above embodiment of the present invention will be listed below. The spinning section is divided into a nozzle member and a spindle member so that it can be freely contacted and separated, and the sliver supplied to the spinning section, which has been considered difficult by a member such as an air sucker member or a transfer arm member, is blown to the hollow spindle tip by air injection. The splicing of a spinning machine that forms a spun yarn while twisting the fibers while spreading the outer periphery of the spun yarn can be automated.

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 completely and quickly performed. Further, the nozzle casing and the like can be completely cleaned by injecting air from the air injection hole for fiber twisting.

A guide member having a guide plate and the like is provided when the spun yarn wound in the package is pulled out and moved upward by the suction pipe, so that the handling and control of the spun yarn such as the 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 finger of the transfer arm member for gripping and sending out the spun yarn is driven and controlled via the accelerator wire member, the spun yarn can be sent out or moved accurately, and the piecing device can be used. It can be made compact.

Since a pair of yarn feed rollers that can be freely contacted and separated is driven and controlled by the accelerator wire, the feed amount of the spun yarn inserted into the spindle member can be accurately controlled. The piecing can be performed reliably and quickly.

Since the drive of the yarn finger of the transfer arm member is 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 improved. Absorption becomes easier.

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 fins are provided on the outer wall of the internal nozzle of the air sucker member, the air flowing in the space formed between the sliding nozzle and the internal nozzle can be reliably prevented from turning into a swirling airflow. The yarn can be kept in a more natural state, and troubles such as the spun yarn being untwisted and cut 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 reduced, and energy can be saved.

The spinning section is divided into a nozzle member and a spindle member so that it can be freely contacted and separated, and the sliver supplied to the spinning section, which has been considered difficult by a member such as an air sucker member or a transfer arm member, is blown to the hollow spindle tip by air injection. The splicing of a spinning machine that forms a spun yarn while twisting the fibers while spreading the outer periphery of the spun yarn can be automated. In addition, the action of inserting the spun yarn into the spindle member and the spinning
Since the defibrating action of the yarn is performed separately,
The operation of the piecing operation can be reliably performed.
Speeding up is possible and the end of the spun yarn is released.
The fibers that make up the sliver can be attached easily.
