Next, as shown in FIG. 22D, the suction pipe lever M is rotated to the substantially vertical standby position as described above. After that, the yarn y sucked and held by the suction mouth m2 and guided by the yarn guiding member G and the package pushing device E, as in the doffing operation described above,
The transfer arm member T is rotated so as to be located near the exit of the yarn y of the spindle member u1 separated from the nozzle member u2, and then the exit of the yarn y of the spindle member u1 separated from the nozzle member u2. Nearby,
Thread y conveyed by transfer arm member T
Is passed through the spindle member u1 by the air sucker n1 of the air sucker N disposed between the nozzle member u2 and the spindle member u1, and then the nozzle member u2
The air sucker n1 is retracted from between the spindle member u1 and the nozzle member u2 and the spindle member u1 are joined, and a sliver is supplied to the draft device to restart the spinning of the spinning unit U. Immediately after the spinning of the spinning unit U is restarted, the detached nip roller u5 is brought into contact with the delivery roller u4 to resume the take-up of the yarn y, the package lifting cylinder d13 is deactivated, and the package P is removed. The package P gripped by the bobbin gripper d9 on the arm d1 ″ side of the cradle arm d1 and the bobbin gripper d8 on the extended cradle arm d5 is rotated by the urging force of the spring d14 in the direction of the drive roller u6. The winding of the yarn y by the package P is restarted by making contact with the rotating drive roller u6.

Next, control means for the spinning unit U and the bogie Ad will be described with reference to FIGS. 23 and 24. FIG.
As shown in FIG. 3, whether or not each spinning unit U can be operated is controlled by a signal from the main control device J. Similarly, the bogie Ad also receives a signal from the main control device J. Controls whether operation is possible or not. When a full-package signal or a yarn breakage signal issued from a known full-package detection unit or a yarn breakage detection unit provided in the spinning unit U is input to the control unit U1 of each spinning unit U, the control unit A service request signal is issued from U1 (for example,
By optical communication using light emitting diodes or the like. ), When the traveling cart Ad receives this service request signal, it stops at the predetermined position of the spinning unit U. Even after the bogie Ad stops at the front of a predetermined spinning unit U requiring a service such as a splicing operation or a doffing operation, a service request signal is sent from the control unit U1 of the spinning unit U to the control unit A1 of the bogie Ad. Sent. While the service request signal continues, the truck Ad
, The bogie Ad continues to stop at the position of the spinning unit U. When the truck Ad stops at a predetermined position of the spinning unit U, a stop completion signal (service acknowledge signal) of the truck Ad is sent from the control unit A1 of the truck Ad to the control unit U1 of the spinning unit U. After the control unit U1 of the spinning unit U receives the service acknowledgment signal of the bogie Ad, the bogie Ad performs doffing work or splicing work based on either the full-package signal or the yarn breakage signal.

If the empty bobbin storage box b9 has no empty bobbin b11 detected by the empty bobbin presence detecting means provided on the truck Ad, or the seed yarn presence detecting means provided on the truck Ad has a seed When it is detected that the seed yarn c4 wound around the yarn package C has been exhausted, such a bogie Ad cannot perform an appropriate doffing operation, so that it is manually or automatically performed. By activating the select switch A2 and activating the full-package signal blocking means U2 provided in the control section U1 of the spinning unit U, the full-package signal issued from the full-package detection section is transmitted to the control section U1 of the spinning unit U. Even if the service request signal is input, the output of the service request signal is blocked. As described above, when the appropriate doffing operation cannot be performed, the service request signal based on the full-fill signal issued from the full-fill detection means is blocked, so that there is no empty bobbin b11 or the seed yarn c4 is exhausted. The bogie Ad is prevented from being stopped uselessly, and passes through the spinning unit U. Therefore, the spinning unit U that requires the splicing operation instead of the doffing operation is required.
The bogie Ad can be moved quickly or reliably to perform the piecing operation.

Signals from main controller J to bogie Ad and spinning unit U are transmitted via repeater j. Signals from the carriage Ad to the spinning unit U (commands for starting the back roller at the time of splicing, activating the nozzle air, connecting and disconnecting the spinning nozzle, etc.) are transmitted via the relay j without passing through the main controller J. Is done. The cutting of the empty bobbin b11 to the empty bobbin supply device and the driving of the conveyor u8 are controlled by the main controller J from the carriage Ad via the repeater j.

[0064]

Since the present invention is configured as described above, the following effects can be obtained.

Since the seed yarn is not wound around the empty bobbin mounted on the bobbin gripping member, there is no need to change the seed yarn depending on the yarn to be spun. Therefore, the workability of doffing is improved. Since the newly spun yarn is wound around the empty bobbin held by the bobbin gripping member, the seed yarn is not wound around the empty bobbin conveyed to the bobbin gripping member. The transfer of the empty bobbin becomes easy.

The seed yarn is pulled out from the seed yarn package placed on the doffing device by the seed yarn gripping means.
Since the drawn seed yarn is stored, the seed yarn does not fall out of the seed yarn transport member during the transfer of the seed yarn.
Therefore, winding after doffing can be reliably started.
