Description

DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION This invention relates to a device for improving the difficulty in temporarily stopping and then restarting the main motor of a single pass rice mill during its operation.

Conventional technology The conventional so-called one-pass rice milling machine has
If you turn off the power switch of the main motor without stopping the supply of brown rice, the rice mill will stop rotating while the resistance cover of the white rice discharge port remains pressurized, so the white rice in the milling chamber will remain firmly filled. become. Therefore, when the main motor is restarted next time, that is, when power is applied to the main motor, a load is applied to the main motor from the beginning, making it difficult to start the main motor.

Problems to be Solved by the Invention The present invention is intended to solve the difficulty in restarting a single-pass rice mill after it is temporarily stopped during operation.

Means to Solve the Problem In a single-pass rice milling machine in which a resistor lid is freely adjustable at the polished rice discharge port of a polishing cylinder with a built-in polishing roll, the adjustment handle of the resistor lid and the power switch of the motor are connected. and synchronizes the time when the resistance value of the resistor lid becomes substantially zero and the time when the power switch is turned off.

Operation To stop operation during polishing, manually operate the adjustment handle on the resistor lid. In conjunction with this operation, operate the main motor power switch to change the position of the adjustment handle on the resistor lid. When the resistance value approaches zero and the polishing cylinder is no longer full of polished rice, the power switch is shut off in conjunction with the adjustment handle and the main motor is stopped.

Next, when restarting operation, grasp the adjustment handle and operate the resistance lid in the direction of increasing the resistance. In conjunction with this operation, connect the power switch and rotate the main motor to remove the polished rice in the polishing cylinder. Operation is restarted while gradually increasing the pressure.

Embodiment An embodiment of the present invention will be described with reference to the accompanying drawings. A milling roll 2 connected to a grain feeding roll 1 is provided concentrically in a cylindrical sugar removal net 3, and a milling chamber 4 is formed between them. and the white rice discharge port 5 of the whitening room 4.
In a single-pass type rice polishing machine in which a resistance lid 6 is freely adjustable, a resistance spring 10 and a resistance rod 1 are attached to the resistance lid 6.
1, and the power switch 9 of the main motor 8 is connected to the adjustment handle 7 via the interlocking rod 12, and when the resistance value of the resistance cover 6 is made substantially zero, the above-mentioned The interlocking relationship is adjusted so that the power switch 9 of the resistor cover 6 can be turned off.

This resistance lid 6 is pressed against the white rice discharge port 5 via a resistance spring 10, and the compression force of the resistance spring 10 is caused by sliding between a resistance cam 14 formed on the back surface of the adjustment handle 7 and a resistance rod 11. is adjusted to adjust the pressing force of the resistance lid 6 against the white rice discharge port 5.

Further, a power switch cam 15 is formed on the back surface of the adjustment handle 7, and the above-mentioned interlocking rod 12 is in contact with this cam 15, and the adjustment handle 7
By rotating the interlocking rod 12, the cam 15
When pressed, the power switch 9 swings about its shaft 16 in the direction of arrow A12 to turn the power switch 9 on and off.

To temporarily stop the illustrated rice milling machine during its operation, first rotate the adjustment handle 7 in the direction indicated by the character "Low", that is, in the direction of arrow A7, to bring it into the state shown in FIG. The pressure is reduced to substantially zero, and when the adjustment handle 7 is at the stop position, the notch 1 of the power switch cam 15 is opened.
The interlocking rod 12 is lowered at 5a to cut off the terminals 9a and 9b of the power switch 9 shown in FIG.

Immediately after the power switch 9 is turned off, the main motor 8 rotates slightly due to its inertia and then stops, during which time the milled rice that is tightly packed in the milling chamber 4 is loosened. In this state, when rotating the rice milling machine next time, move the adjustment handle 7 in the direction of arrow 7B shown on its surface.
That is, when rotated in the direction indicated by the character "strong", the interlocking rod 12 is pushed and moved by the resistance cam 14 of the power switch 9, presses the resistance spring 10, and directs the resistance lid 6 toward the white rice discharge port 5. to force.

At the same time, the interlocking rod 12 connected to the power switch cam 15 on the back of the adjustment handle 7 is rotated in the direction of arrow A12 as shown in FIG. 4, the power switch 9 is connected, and the main motor 8 is turned on. The grain feeding roll 1 and whitening roll 2 are rotated to start whitening.

Note that 17 is a brown rice hopper, 13 is a brown rice supply shutter, and 19 and 20 are a single-phase power source and a three-phase power source, respectively.

Although the present invention has been described above with reference to the embodiments shown in FIGS. 1 to 4, the present invention is not limited thereto. The present invention can be implemented by making partial additions or changes within the scope of the gist of the present invention, such as using a three-phase motor as shown in the figure.

Effects Since the present invention has the above-described structure and operation, when the single-pass type rice milling machine is in operation and when it is stopped, if the power switch 9 is turned off by operating the adjustment handle, the power switch 9 can be turned off immediately before the rice milling machine is stopped. The pressure acting on the resistance lid 6 of the polished rice discharge port 5 becomes substantially zero, and the whitening chamber 4
Since the load inside the rice milling machine is removed and the rice milling machine completely stops, the next time the rice milling machine is restarted, no overcurrent flows to the main motor 8 at the time of startup, and the restarting of the rice milling machine can be carried out extremely easily and reliably. Can be done.
