Carrying an empty tray is discharged from the spinning machine 1 side out path L ₁₁
And a circulation path L ₁₂ for returning the actual bobbin, which has missed the yarn end ejection in the yarn ejection device 4, to the yarn ejection device 4 again.

When a small amount of thread remains on the bobbin inserted into the tray carried from the carry-out path L ₁₁ to the carry-out path L ₂ ,
The bobbin stripper 8 removes the residual yarn and returns it to the spinning machine 1 through the carry-out path L ₂ as an empty bobbin. Also,
When the come transported to discharge line L ₂ from the discharge path L ₁₁ trays remain yarn bobbins thirds ball of insertion is returned to the device 4 out again mouth than the circulation path L _12.

A stopper 9 for waiting the actual tray is provided near the downstream end of the unset actual bobbin standby path L ₃ , and a steam setter 5 is provided near the downstream end of the set actual bobbin standby path L _7. Stoppers 10 for waiting the actual trays that have been processed and dried by the drying device 7 are provided.

As shown in FIG. 2, the preheating device 6 and the drying device 7 are juxtaposed in one housing with a partition plate 11 interposed therebetween.

Below the passage L ₄ of the preheating device 6, there is arranged a hot air supply pipe 12 in which holes 12a are formed at an interval slightly longer than the outer diameter of the tray T (hole 12a in FIG. 4).
Are indicated by dotted lines at equal intervals). Hot air is sent to the hot air supply pipe 12 via a pipe 14 from a heating chamber 13 having a built-in heater for heating the air sucked from the air intake port 13a. Of course, holes corresponding to the holes 12a of the hot air supply pipe 12 are also formed in the bottom of the passage L ₄ at equal intervals.

[0014] hot air blown up from the hole 12a of the hot air supply pipe 12, passes through the center of the bobbin B from the center of each tray T in a row in the passage L _4, warm the bobbins B.

A fan 15 for taking in outside air is provided inside the drying device 7, and the partition plate 1 is also provided.
The exhaust gas of the preheating device 6 is sent from above 1. Each of these airflow, full bobbin moist discharged from the steam setter 5 is dried while passing through the passage L _6. Then, the airflow is discharged from below the drying device 7.

[0016] Between the passage L ₄ of the preheater 6 and passage L ₆ of the drying device 7, as shown in FIG. 5, each tray T in the passage L ₄ and passage L ₆ in opposite directions to each other A transfer plate 16 for intermittently transferring one pitch at a time is arranged.

The transfer plate 16 has a plurality of protruding pieces 16a on both sides thereof at the same intervals as the holes 12a of the hot air supply pipe 12.
The transfer plate 16 repeats forward, rightward, backward, and leftward movements as shown by the four arrows on the right side of FIG. The movement is performed by an air cylinder for right and left rows, not shown, and an air cylinder for forward and backward movement.

When the transfer plate 16 moves forward from the state shown in FIG. 5 (moves to the left side in FIG. 5), each projection 16a on the passage L ₄ side of the preheating device 6 has a central portion of the tray T in the passage L _4. And push each projection T forward to move the tray T forward by one pitch. Next, the transfer plate 16 is Migigyo, projections protruding pieces 16a of the passage L ₆ side of the drying device 7 together with the engagement of the tray T in passage L ₄ is released tray T in passage L ₆ Enter behind. After that, the transfer plate 16 retracts (see FIG.
Movement to the right), the left tray T in passage L ₄ is stopped, the tray T in the passage L ₆ is one pitch advanced medium passage L _6.

Finally, a nozzle 17 for injecting air toward the tray T in the passage L ₅ is provided near the outlet of the steam setter 5. The air flow ejected from the nozzle 17 blows off the water droplets condensed on the tray T in the steam setter 5.

In the steam setting device thus constructed, the actual bobbin carried in from the carry-in path L ₁ is sent to the unset actual bobbin standby path L ₃ and stopped behind the stopper 9. When the preheating device 6 has a space, it is taken into the preheating device 6 and the bobbin is warmed. Next, steam treatment is performed in the steam setter 5, but since the bobbin is heated, dew condensation does not occur on the bobbin. Subsequently, it is dried in the drying device 7, and the set actual bobbin standby path L ₇
And is stopped in front of the stopper 10 in order.
Then, the released stopper 10 every time there is a capture request from the lead unit 4, yarn end finding process is performed is sent to one by one port out device 4, it is released into the feed channel L _8. afterwards,
The tray is sent to the introduction path L ₉ , circulates, and is taken up by the weight for which the take-up is requested. The empty tray that has been wound up advances from the discharge path L ₁₀ to the carry-out path L ₁₁ , the residual yarn is removed by the bobbin stripper 8, and the empty tray is returned to the spinning machine 1 through the carry-out path L ₂ .
