Description

[Detailed description of the invention] The present invention has a function that can operate a blower as needed when threading the yarn supplied to the magazine tube, and also uses a yarn breakage sensor to issue a yarn knotting command. This invention relates to a blower control device for an automatic wine gourd, which has a function of automatically starting a blower when a signal is issued and automatically stopping the blower when a thread tying operation is completed.

Due to the function of the automatic wine goo, the blower is required to operate when taking out the thread from the supplied pipe yarn or when tying the yarn, and there is no need for the blower to operate other than that, and in fact, it is stopped. This is more desirable from the viewpoint of reducing noise and power consumption.

However, in the conventional wine goo, once the floorer is started, the mechanism continues to operate at all times until the entire wine goo is stopped, which results in large losses in terms of power consumption as mentioned above, and also in terms of noise. Problems in workability, etc. are also likely to occur.

Furthermore, when the yarn end of the pipe yarn supplied to the magazine tube is sucked and taken out, a constant suction airflow is applied to the taken out yarn end, which loosens the yarn end and blows away the fibers that make up the spun yarn. As a result, the length of the suctioned yarn end decreases.As a result, the yarn end that was pulled out when the tube yarn was dropped to the winding position is pulled out from the suction device as the tube yarn falls, and the yarn end at the winding position and the magazine tube are no longer connected. There will be no thread between the ends, and the end of the side thread will be caught incorrectly during the thread tying operation.

The present invention will be explained in detail below based on the drawings.

Fig. 1 shows a schematic diagram of an automatic wine goo, in which the thread end of the pipe thread 1 supplied to the magazine tube M is suctioned by operating the blower 8 shown in Fig. 2 in an operation described in detail later. and is sucked into the suction hole 2a.

After the yarn end is suctioned, the tube yarn 1 slides through the shooter 3 and is set in the state 1a on a support rod (not shown).

Further, a winding unit 7 is mounted and fixed on a shaft 5 supported by the frame 4 and an air conduit 6, and a suction nozzle 8 and a pipe are connected to the air conduit 6 and suck and capture the yarn end from the winding package 10. The suction nozzle 9, which suctions and captures the yarn end from the yarn 1, rotates and knocks both yarn ends.
Nok-11 performs the thread tying work.

When the thread Y to be wound is running, the thread Y is provided with a balloon breaker 12, a tension device 13, a thread breakage sensor 15 that detects that the thread is not running normally and activates a microswitch 14; slab catcher-16,
It is acted upon by the traverse drum 17.

At the end of the air conduit 8, a blower 1 is installed as shown in FIG.
8 is connected.

This blower 18 is separated from a fan 19 and a drive motor 20, and the rotation of the drive motor 20 is transmitted to the fan 19 via a fan belt 23 between pulleys 21 and 22.

Therefore, when the air flow in the air conduit 6 passes through the net 24 and flows out to the outside, a negative pressure is generated in the air conduit 6.
a suction nozzle 8 attached to one end of the air conduit 6;
9 and the suction hole 2a formed in the center of the suction device 2, a suction force is generated.

FIG. 3 shows the control circuit of the present invention.

In addition, in the following explanation, ``normally open contact'' refers to a contact that is closed when no current is flowing through the relay.
“Normally open contact” means a contact that is open when no current is flowing through the relay.

When the foot switch FS connected in parallel with the normally open contact r-2 of the relay R-2 is turned on by direct manual operation, the main contact mc is activated by the operation of the electromagnetic switch MC connected in series with the foot switch FS. is closed, thus starting the drive motor IM and operating the blower 18 via the fan belt 23.

When the sensor 15, which detects whether the thread is running normally, detects the occurrence of thread breakage, the current is cut off and the normally closed contact r-1 of the relay R-1 is closed.

At that time, relay R-2 connected in series with the contact r-1
The normally open contact r-2 of the electromagnetic switch MC is closed, and the normally open main contact mc of the electromagnetic switch MC is also closed.

Therefore, the drive motor IM is started, and the blower 18 is operated via the fan belt 23.

Moreover, when the contact r-1 is closed, the solenoid SQL connected in series with the contact r-1 is turned on, and the knock-1 is turned on.
1 starts and performs thread tying work.

When the thread tying is completed, the limit switch LS snaps into action due to the operation of the cam 25, and at this time, the contact r
-2 is opened, contact r-1 is opened, main contact MC is opened, the blower is stopped, and solenoid SQL is turned off, and the thread tying operation is stopped.

In addition, when eddy current occurs in TR-1 and TR-2,
Regarding the normally closed contact th-3, a thermal relay for interrupting current, KS is a knife switch.

That is, to summarize the present invention, when the yarn end of the yarn 1 supplied to the magazine tube M is turned on by direct manual operation of the foot switch FS, the drive motor 20 is driven, and there is a connection between the drive motor 20 and the blower 18. The air is transmitted through the wound fan belt 23, and the blower operates.

When the blower is operated, a negative pressure is generated in the air conduit 6, and a suction effect is generated in the suction device 2 attached to one end of the air conduit.

By pouring the yarn end into the suction hole 2a of the shaft of the suction device 2, the yarn end is suctioned, and when the yarn end is finished, the foot switch FS is turned off to complete the yarn end letting out process.

Also, when a yarn breakage is detected by the yarn breakage sensor 15 during winding work from the tube yarn 1 to the winding package 10, relays R-1 and R-2 are activated, and furthermore, the electromagnetic switch MC is activated and driven. The motor 20 is driven.

When the drive motor 20 is driven, negative pressure is generated in the air conduit 6 as described above, and suction force is generated in the suction nozzle 8°9 connected to one end of the air conduit 6, causing the winding package 10 to be removed. The yarn end is suctioned and captured by the suction nozzle 8, and the yarn end from the tube yarn 1 is captured by the suction nozzle 9.
Capture by suction.

At the same time as suction capture of the suction nozzles 8 and 9, the relay R
Solenoid SQL connected in parallel with knock-2 operates to operate knock-11 to tie the thread.

When the thread tying is completed, the micro switch 6 is activated by the cam 25, and the relay R-1 is turned on.
Relay R-2 and solenoid SQL are turned off.

Therefore, the thread tying operations in the blower 18 and the knock 11 are stopped.

In addition, in the present invention, when taking out the yarn supplied to the magazine tube, the foot switch FS is activated to suck the yarn end into the suction hole 2a of the suction device 2, and by turning off the switch FS, the yarn end is removed from the suction hole 2a. In this state, a request command from the winding unit is received, and during this time, the suction airflow is not acting, so the yarn end does not untwist and break, and when tying the yarn, the winding position 1a is When the bobbin is empty, the empty bobbin is discharged, and one of the bobbins waiting in the magazine tube M is supplied to the winding position 1a through the chute 3. However, at this time, since the blower is already operating according to the thread tying command signal, suction and one suction air flow are simultaneously applied to the suction device 2 of the magazine pipe M, so that when the pipe thread falls, the suction The yarn end in the hole is held by suction, and as the yarn falls, the yarn is pulled out from the tube. When the yarn reaches the winding position 1a, there is no yarn between the yarn at position 1a and the magazine tube M. In this way, the suction nozzle 9 can reliably suction and capture the ends of the side yarns.

As described above, in the present invention, the following experimental results were obtained by operating the blower only when the yarn was being fed, when the yarn was being fed, and when the yarn was tying when a yarn breakage occurred.

As mentioned above, compared to the conventional wine goo machine, we were able to obtain good results in terms of power savings of 72 to 88% as shown above.

In addition, noise was reduced and work efficiency was further improved.

In addition, untwisting and breakage of the thread end that has been pulled out is prevented, and the thread is dropped and supplied to the winding position while the thread end is held in the suction device of the magazine. Edge capture can also be performed reliably.

Furthermore, even if the motor is operated for a long period of time, the motor will not heat up, and therefore the ambient temperature will not rise, so the air drying caused by the high temperature heating of the motor will cause static electricity to build up on the yarn, which will easily adhere to the winding drum surface and cause yarn breakage. It is possible to prevent accidents that occur, and winding can be carried out in a favorable environment.
