Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention particularly relates to an oil supply device for a bobbin used in a ring spinning machine.

[Prior Art] Generally, the yarn wound on the bobbin by the ring spinning machine is rewound into the package by the winder. Therefore, the full bobbin fried in the ring spinning machine is conveyed to the winder process, and the empty bobbin after the yarn is unwound by the winder is conveyed again to the ring spinning machine for recycling. When winding the yarn on the bobbin with the ring spinning machine, in order to make the shape of the tube yarn uniform and to smoothly perform the doffing work by the doffing machine,
It is necessary to insert the bobbin to the predetermined position on the spindle. However, since cotton dust, dust, etc. are suspended in the spinning factory, when the bobbin is used for a long time, the cotton dust adheres to the inner surface of the bobbin and the insertion force required to insert the bobbin into the spindle of the spinning machine is reduced. It becomes large and it becomes difficult to insert the bobbin to a predetermined position. Therefore, conventionally, the bobbins are regularly collected, and the inner surface of the bobbin is manually coated with silicon oil or the like so that the insertion force into the spindle is returned to a predetermined magnitude.

[Problems to be solved by the device] However, a ring spinning machine usually has 200 weights on one side and a total of 4 on both sides.
The number of spindles is 00, and the number of spindles per spinning machine is increasing due to the large number of spindles. Therefore, in order to apply the oil to the inner surface of the bobbin without lowering the operating efficiency of the spinning machine, it is necessary to prepare a large number of extra bobbins.
There is also a problem that the oil application work is labor-intensive and therefore takes a lot of time.

The present invention has been made in view of the above problems, and an object thereof is to provide a device capable of automatically applying oil to the inner surface of a bobbin without preparing an extra bobbin.

[Means for Solving the Problems] In order to achieve the above-mentioned object, in the present invention, a spinning bobbin is inserted into a peg tray and conveyed to a winder side by a conveying device, and a full bobbin is inserted into the winder side. A peg tray mounted on the bobbin is intermittently moved and guided so that the yarn end is ejected, and the yarn end is inserted from the top of the bobbin to the inside of the bobbin by using a suction airflow. A compressed air jet nozzle for causing compressed air to act on the full bobbin at the time of dispensing is provided, and the nozzle tip is located above the tray stop position before the dispensing position of the dispensing device so as to face the bobbin top. A pipe for arranging the oil injection device, and for branching the compressed air supplied to the compressed air injection nozzle of the outlet device to the oil injection device. Set up a road,
The oil injection device is configured to inject oil in a mist form from the tip of the nozzle by using compressed air passing through the conduit.

[Action]

In the device of the present invention, the oil injection device is provided above the tray stop position before the output position of the output device mounted on the winder, and the bobbin is arranged at the tray stop position so as to face the bobbin top. Oil is sprayed in a mist form from the tip of the nozzle arranged at the position. As a result, it is not necessary to collect the bobbins and perform manual work for applying the oil.

Here, in the case where cotton wool etc. are accumulated in the bobbin,
The oil will soak into the cotton wool and the like, and the cotton wool will be discharged due to the momentum of the oil injection.However, the cotton wool that has been soaked with oil may not be completely discharged, or the excess oil is dripping on the inner surface of the bobbin. Even if it adheres to the
The cotton wool or the like soaked with the oil or the oil adhering to the inner surface of the bobbin in a droplet form is discharged from the inside of the bobbin to the outside.

Further, when the oil is sprayed in the form of mist by the oil injection device, the compressed air supplied to the compressed air jet nozzle of the outlet device is branched, and the branched compressed air is used for the oil injection. The conduit structure for guiding is simplified as a whole.

〔Example〕

An embodiment in which the present invention is embodied in a spinning winder for carrying a full bobbin and an empty bobbin using a peg tray will be described with reference to the drawings.

As shown in FIG. 2, a main conveying path 3 (only a part is shown) forming a closed loop is arranged between a plurality of spinning machines 1 and one winder 2 which are installed in parallel with each other. Is connected to the main transport path 3 via a transport path for loading 4 and a transport path for unloading 5 as a transport device. Only the peg tray 6 having a full bobbin inserted at the entrance of the carry-in transport path 4 is guided to the carry-in transport path 4, and the peg tray 6 having an empty bobbin inserted is configured to go straight on the main transport path 3. The known sorting device 7 is provided. The carry-in carrying path 4 extends along the rear side of the winding unit 8 so that the peg tray 6 is carried, and the carry-out carrying path 5 extends along the front side of the winding unit 8.

A feeding device 9 is arranged near the entrance of the carry-in transport path 4. The dispensing device 9 has a configuration similar to that of a known device (for example, Japanese Patent Laid-Open No. 61-155172), a suction mouth 10 for sucking the thread end of the full bobbin F inserted in the peg tray 6, and a peripheral portion. Many (8 in this embodiment)
And the rotary plate 11 which is intermittently rotated and which is provided with the engaging recess 11a. Then, the full bobbin F inserted into the peg tray 6 which has entered the carry-in carrying path 4 from the main carrying path 3 is sequentially arranged at a position corresponding to the suction mouth 10 through the bunch winding cut portion (not shown). The thread end is sucked into the suction mouth 10 and the thread is pulled out from the full bobbin F, and then the thread end cut into a predetermined length is formed in the peg from the bottom side of the peg tray 6 to the peg (not shown).
It is designed to be inserted inside the top of the bobbin by the suction airflow acting on the bobbin via. Further, since the dispensing device 9 does not have a top bunch winding, it is possible to dispense the bobbin in which the yarn end is attached to the yarn layer surface of the full bobbin F (for example, Japanese Patent Laid-Open No. 61-45870). A compressed air jet nozzle (not shown) is arranged at a position corresponding to the suction mouth 10 (similar to the device disclosed in the publication).

At the position corresponding to the predetermined stop position of the peg tray 6 before (in this embodiment, one before) the ejection position of the ejection device 9, the tip of the nozzle 13 is located at a position where the oil injection device 12 faces the top of the bobbin. It is arranged to be located. The oil injection device 12 has a known structure in which oil is atomized from a nozzle by the action of compressed air. The oil injection device 12 is connected through a pipe line 16 to a distributor 15 provided in a pipe line 14 for supplying compressed air to the compressed air jet nozzle of the outlet device 9, and the compressed air is supplied to the compressed air jet nozzle. Compressed air is supplied at the timing. The pipe line 16 is bifurcated, and one of the branch lines 16a is connected to the oil injection device 12
And the other branch 16b is connected to the nozzle 13. Further, a switching valve 17 is provided at the branch portion of the pipe line 16.

Next, the operation of the device configured as described above will be described.
Since it is sufficient to apply the oil to the bobbin about once every half a month, normally the compressed air is not supplied to the main body of the oil injection device 12 but is directly supplied to the nozzle 13
The spinning winder is operated with 17 being switched. In this case, the peg tray 6 that has entered the carry-in transport path 4 is guided to the ejection device 9, and when the rotary plate 11 is intermittently rotated, the peg tray 6 is stopped at a predetermined position one position before the sequential ejection position. The compressed air supplied to the passage 16 is directly supplied to the nozzle 13 via the branch passage 16b. That is, compressed air containing no oil is jetted from the nozzle 13. The compressed air injected from the nozzle 13 to the inside of the bobbin has a function of removing the cotton dust and the like existing inside the bobbin from the through hole formed in the peg to the outside.

When it is time to apply oil to the bobbin, the switching valve 17 is operated to switch so that the compressed air supplied to the conduit 16 is supplied to the main body side of the oil injection device 12. In this case, the peg tray 6 in which the full bobbin F is inserted is attached to the nozzle 13
When stopped at a predetermined position corresponding to the tip of the, the compressed air is supplied to the main body of the oil injection device 12 via the branch passage 16a of the pipe 16, and atomized oil is injected from the tip of the nozzle 13 into the bobbin. Oil is automatically applied inside the bobbin. The full bobbin F inserted in the peg tray 6 is a rotating plate.
The intermittent rotation of 11 surely stops at a position corresponding to the nozzle 13, and atomized oil is ejected from the nozzle 13 when stopped. After a lapse of time necessary for the bobbin used in the spinning spinning winder to complete a cycle, the switching valve 17 is switched to a state in which compressed air is directly supplied to the nozzle 13 again. Similarly, when the oil application timing for the bobbin comes, the switching valve 17 is operated to apply the oil.

As described above, the great advantage of supplying the oil at the position before the outlet position of the outlet device 9 using the air flow is that the oil is soaked and the cotton wool or the like is not completely discharged, or the excess oil is not discharged on the inner surface of the bobbin. Even if it adheres in the form of drops, the mouthpiece device 9 that is placed behind the oil injection device 12
The action of the air flow is that the cotton wool or the like soaked with the oil or the oil adhering in drops on the inner surface of the bobbin is discharged from the inside of the bobbin to the outside.

Further, in the present embodiment, the compressed air supplied to the compressed air ejection nozzle of the outlet device 9 is branched, and the branched compressed air is supplied to the oil injection device 12 via the pipe 16. As a result, a complicated structure in which a compressed air supply source is separately provided for the oil injection device 12 and the supply source and the oil injection device 12 are connected by a pipe is unnecessary, and the pipe line configuration is simplified as a whole. .

The present invention is not limited to the above-described embodiment, and for example, the pipe 16 may not be bifurcated and the nozzle 13 may constantly spray a small amount of mist-like oil.

[Effect of device]

As described in detail above, according to the present invention, oil is automatically applied to the inside of the bobbin. In addition, even if the cotton wool that has soaked in the oil is not completely discharged by applying oil to the inside of the bobbin, or if excess oil adheres to the inner surface of the bobbin in the form of drops, the oil is put in the latter stage of the oil injection device. Due to the action of the suction airflow of the dispensing device, the cotton wool or the like soaked with oil or the oil adhering to the inner surface of the bobbin in a droplet form is discharged from the inside of the bobbin to the outside. As a result, it is not only necessary to collect the bobbin in another place for oil application, but also the insertion force required when inserting the bobbin into the spindle is always maintained at a predetermined value, so that the bobbin can be inserted into the spindle. Definitely done. Further, when the oil is sprayed by the oil injection device in a mist state, the compressed air supplied to the compressed air injection nozzle of the outlet device is branched, and the branched compressed air is used for the oil injection. The conduit structure for guiding is simplified as a whole.
