BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic rice milling machine.

[0002]

BACKGROUND Conventionally, rice how Sessu closing regulating the frictional chamber resistor valve by frictional resistance motor so that optimum load conditions while rice was fed to the friction rice chamber brown rice is known.

[0003]

The known rice milling method comprises:
When rice is one separated Lisa and settles, frictional chamber resistor valve set to optimum load state is also open Kukara, when rice resumed, just as optimum load state so as to open and close the frictional chamber resistor valving and it has had a troublesome.

[0004]

The object of the present invention is to eliminate the need for adjusting the resistance valve for the friction chamber when restarting rice polishing.

[0005]

Accordingly, the present invention is to adjust the opening and closing of the friction chamber resistance valve 30 by the friction resistance motor 27 so that the brown rice supplied to the friction milling chamber 9 is brought into an optimal load state while polishing the brown rice. Then, the adjustment completion state of the resistance valve 30 is stored in the ram storage unit 41 of the control circuit. When the supply of brown rice is completed, the brown rice detection sensor 25 detects this and the friction valve resistance valve 30 is set to the optimal load state. automatically opens taken out the remaining rice and from the a predetermined time elapses ram memory 4
The gist of the invention is an automatic rice polishing method in which the resistance valve 30 is automatically closed by the frictional resistance motor 27 and the next rice polishing is performed until the optimum load state is reached based on the numerical value stored in 1.

Next, the operation will be described. a. When the knob of the frictional resistance adjusting switch 36 is manually operated in the strong or weak direction, a numerical value is set in the frictional resistance window 38. This numerical value may be an appropriate numerical value determined by those skilled in the art. In one example, it is determined around " 63 " . In conjunction with this operation, by energizing the friction motor 27, the rotating wheel 26 is horizontally rotated, against the elastic force of the spring 28, to adjust the inclination of Hasu杆29, up and down the bran removing cylinder 3 Let the friction chamber resistance valve 30
And Ru are interlocked adjusted so that the value.

B. Then, turning on the operation button operated switch 33, Chokomi lifts 16 rotate, finishing and circulating elevator 20 also rotates, friction rice roll 2 is rotated by a friction roll motor 8. The shutter 13 is closed
I have.

C. Next, the close button of the on- off valve switch 35 is pressed, and the on-off valve 14 is closed by the on-off valve motor 15.

D. Next, the circulation button of the switching valve switch 34 is pressed to return the switching valve 21 to the gutter 23 side via the motor or the solenoid 22.

E. Next, the numerical value of the flow rate value window 39 is set by operating the flow rate adjusting switch 37. Still, the shutter 13 and the on-off valve 14 are still closed.

F. Next, brown rice is stuffed into the stuffing mouth 17.
The shutter 13 is fully opened manually.

G. The brown rice that has been lifted by the elevator 16
After reaching the sensor 25 via the storage tank 12, the sensor 25 is turned on. After a few seconds (at some point), open and close
When the open button of the valve switch 35 is pressed and turned on, the open / close valve 14 is opened by energizing the open / close valve motor 15 by the amount indicated by the window 39 of the flow rate value determined by the flow control switch 37, and the open / close valve 14 in the storage tank 12 is opened. Brown rice is supplied into the grain sending cylinder 5,
It is made to flow into the friction rice mill 9 by the lower feed spiral roll 4,
Friction is polished by the polished rice roll 2, taken out from the take-out pipe 19, lifts the finishing / circulating lift 20, returned from the switching valve 21 to the storage tank 12 via the return gutter 23, and circulated and polished.

H. When the rice discharged from the take-out pipe 19 is inspected and the frictional resistance adjusting switch 36 is finely adjusted, the motor 27 for frictional resistance is energized to rotate the rotating wheel 26 horizontally, thereby resisting the elasticity of the spring 28. Then, the inclination of the oblique rod 29 is rapidly and gradually adjusted, and the bran removing cylinder 3 is moved up and down to adjust the resistance valve 30 for the friction chamber.
The load becomes appropriate . In conjunction with this, the numerical value of the window 38 changes, and the numerical value is stored in the ram storage unit 41 via the input / output circuit 40 of FIG.

I. H. In the inspection of the discharged rice from the take-out pipe 19, it is recognized that the initial milling is completed, and the discharge button of the switching valve switch 34 is pressed, and the switching valve 21 is moved to the discharge gutter 2.
Switch to the 4 side and transfer the polished rice to the next step.

J. When brown rice runs out, sensor 25
Detects the absence of brown rice and rubs through the input / output circuit 40
By directly energizing the resistance motor 27 , the rotating wheel 26 is horizontally rotated, the inclination of the oblique rod 29 is set to a gentle inclination against the elasticity of the spring 28, and the bran removing cylinder 3 is moved downward for the friction chamber. Open the resistance valve 30 and remove the remaining rice. At this time, the numerical value of the window 38 becomes 0.

K. If there is a blower, energize the motor and send air to clean it for a few seconds.

L. The blower is automatically stopped after a few seconds, and at the same time, according to the numerical value stored in the ram storage unit 41, a current is supplied to the frictional resistance motor 27 via the input / output circuit 40 to horizontally rotate the rotating wheel 26, and the spring 28 Against the elasticity of
And steeper the slope of Hasu杆29, closed <br/> Jill the bran removing cylinder 3 to the state in which the upper movement is allowed optimum load conditions the frictional chamber resistor valve 30 resulting.

M. Put the brown rice of each lot into the spout 17. Milling is performed according to the above sequence.
It is not necessary to set 0.

[0023]

According to the well-known milling method, when the milled rice is separated in one paragraph, the resistance valve for the friction chamber in the optimum load state is also opened, so that when the milling is restarted, the optimum load state is similarly obtained. Opening and closing the friction chamber resistance valve
It was troublesome. However, according to the present invention, the resistance valve 30 for the friction chamber is opened and closed by the friction resistance motor 27 so that the brown rice supplied to the friction milling chamber 9 is milled so as to be in the optimum load state. Is stored in the ram storage unit 41 of the control circuit. When the supply of brown rice is completed, the brown rice detection sensor 25 detects this and automatically opens the friction chamber resistance valve 30 from the optimal load state to remove remaining rice. After a certain period of time, based on the numerical value stored in the ram storage unit 41, the friction valve motor 27 automatically closes the resistance valve 30 and automatically mills the next milled rice until the optimum load state is reached. Since the method is a gist, it is not necessary to readjust the resistance valve 30 when restarting rice polishing.
