BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a steam set apparatus for connecting a spinning machine and an automatic winder, and circulating a bobbin inserted in a tray between the spinning machine and the automatic winder to perform steam processing.

[0002]

2. Description of the Related Art Generally, when a spun yarn supplied to an automatic winder is a yarn or the like, a torque acts on the yarn to be unwound when twisting in a later step. In a bobbin processing system for connecting a spinning machine and an automatic winder, a steam setter (see Japanese Patent Application Laid-Open No. 61-215728) for performing a steaming process before sending a spun yarn to an automatic winder is provided to reduce the torque of the yarn. I am erasing.

[0003]

Water droplets condense and adhere to the surface of the bobbin discharged through the above-mentioned steam setter, and the dew drops wet the yarn wound near the bobbin surface to degrade the quality. There is fear.

The purpose of this invention is to prevent the dew condensation from occurring on the surface of the bobbin by preheating only the bobbin of the spun yarn to be fed into the steam setter.

[0005]

In order to achieve the above object, the steam set device of the present invention is provided with a preheating device for blowing hot air into a bobbin center hole in front of a steam setter.

[0006]

[Operation] In the steam set device configured as described above, when the spun yarn is taken into the preheating device and hot air is blown into the bobbin center hole, only the bobbin itself is heated. Then, when the spun yarn is steam-set by a steam setter, the bobbin is heated, so that dew condensation does not occur. Further, since the temperature of the yarn wound on the bobbin does not rise, the transfer of steam is performed smoothly.

Carrying an empty tray is discharged from the spinning machine 1 side out path L ₁₁
If, which is more a circulation passage L ₁₂ back to the lead unit 4 a full bobbin with the yarn end finding mistakes yarn end out again mouth 4.

[0010] If the thread is left little to the discharge line L ₂ to the carried the incoming tray to the insertion of the bobbin from the feed-out path L ₁₁ is,
Residual thread is removed by the bobbin stripper 8, it is returned to the spinning frame 1 from out path L ₂ in the 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.

[0011] In the vicinity of the downstream end of the unset completed bobbin waiting path L _3, stopper 9 for waiting the actual tray, also in the vicinity of the downstream end of the set actual bobbin waiting path L _7, steam steam setter 5 Stoppers 10 are provided for holding the processed and dried actual trays in the drying device 7, respectively.

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 12 a are drilled upward at intervals slightly longer than the outer diameter of the tray T.
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 hole in the bottom of the passage L ₄ corresponding to the hole 12a of the hot air supply pipe 12 is bored 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.

Thus, when the bobbin B is heated from the center hole, only the bobbin itself can be heated. When the temperature of the yarn wound on the bobbin B becomes high, the steam is not transferred when the steam is processed by the steam setter 5,
If only the bobbin itself is heated in this way, the steam can be smoothly transferred.

At the upper part of the drying device 7, a fan 15 for taking in the outside air is provided.
Exhaust gas from 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.

[0017] Between the passage L ₄ of the preheater 6 and passage L ₆ of the drying device 7, as shown in FIG. 5, passage L ₄ and the respective trays T in the passage L ₆ in opposite directions to each other A transfer plate 16 for intermittently transferring one pitch at a time is provided.

The transfer plate 16 has a plurality of projecting pieces 16a on both sides thereof at the same interval as that of each hole 12a of the hot air supply pipe 12.

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. Thereafter, the transfer plate 16 is retracted (FIG. 5).
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.

[0020] Finally, in the vicinity of the outlet of the steam setter 5, a nozzle 17 for injecting air toward the tray T in the passage which L ₅ is provided. Due to the air flow ejected from the nozzle 17, water droplets condensed on the tray T in the steam setter 5 are blown off.

In the steam setting apparatus thus configured, 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 becomes empty, it is taken into the preheating device 6 and hot air is blown into the bobbin center hole, so that only the bobbin is heated. Next, the steam is set in the steam setter 5, but the yarn wound on the bobbin B is not heated, so that the steam is smoothly transferred, and the bobbin B is warmed. Does not occur. Subsequently, it is dried in the drying device 7, paid out to the set actual bobbin standby path L ₇ , and 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. Thereafter, the tray is circulated sent to introduction path L _9, incorporated into the spindle with a capture request. In addition,
Empty tray take-up has been completed, carry-out path L from the discharge path L ₁₀
Advances to _11, the remaining yarn are removed by the bobbin stripper 8, it is returned to the spinning frame 1 from out path L ₂ in the empty bobbin.

[0022]

[Effects of the Invention] The present invention is configured as described above, and has the following effects.

That is, when the spun yarn is steam-set by the steam setter, since only the bobbin is already heated, no dew condensation occurs on the bobbin of the set spun yarn, and the wound yarn is wound near the bobbin surface. No loss of quality is obtained by wetting the yarn. Further, since the temperature of the yarn wound on the bobbin does not rise, the steam can be smoothly transferred in the steam setter.
