Description

[Detailed description of the invention] This article relates to automatic rice polishing equipment.

If the rice milling operation is stopped during milling in a rice milling machine, the grains being milled will remain filled in the milling chamber together with the peeled surface carbohydrates, and the grain temperature will rise due to friction during the milling process. As the rice mill cools down when the rice mill is stopped, it coagulates with the bran etc. When it is restarted, a large load is generated and there is a risk of damage to the motor. Therefore, before stopping the milling operation, the supply of grains to the milling chamber is cut off by closing the shutter, and we wait until the grain in the milling chamber becomes empty to some extent and becomes suitable for operation again. It has been stopped artificially. In addition, all other operations related to rice milling work are performed manually.

Therefore, it was necessary to constantly monitor the work, and it was not suitable for the current situation where labor saving is required.

The present invention aims to solve these problems, and its purpose is to automate the rice milling process.
This seems to be a measure of labor saving.

Next, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 shows the configuration of an embodiment of the present invention, in which 1 is a hopper, 2 is a feeding device for the hopper 1, 6 is a shutter,
Ml is the motor for milling rice, M2 is the motor for feeding device 1, S
4. S2 is a detector, SOL is a solenoid, and C is a controller.

The shutter 3 is normally closed, but is opened during operation, and when the detector S0 is turned on, the shutter 3 is closed by the solenoid → SQL and locked in this position. This lock is released when the motor is started.

The detector S1 is turned on when the number of grains is less than the detector S1, and is turned off when there are grains above the detector S1.It is a proximity switch, a limit switch, a photoelectric switch, etc. can be used.

The detector S2 is turned off when there are fewer grains than the detector S2, and turned on when there are grains above the detector S2, and the same detector as the detector S is used. Also, the installation location should be such that it can detect when the hopper is full under normal conditions.

Controller C is composed of a microcomputer and includes detectors S1.
The signal from S2 causes solenoid SQL, motor M,...
It controls M2. In this case, it is also possible to check the degree of rice polishing and control the degree of polishing of the rice based on the detected value.

FIG. 2 explains the operation of the embodiment shown in FIG.

The motor M1 is started to perform rice polishing work for a predetermined time.

During this work, if there are no grains in the hopper 1, Sl will detect this, and the signal will cause the solenoid SQL i
It operates, closes the shutter 3 and starts the motor pigeon. Then, after a certain period of time (for example, 5 seconds), the motor Mtk is stopped.

The shutter 3 is opened at the same time as the Ml is started. Then, when the hopper is full, the detector S2 is turned on, and the signal causes the simulator pigeon to stop. Then, the rice polishing operation is performed while repeating the above process until a predetermined time.

FIG. 3 uses sequence control instead of the microcomputer control in FIG. 1. In the drawings, the same members as in FIG. 1 are designated by the same reference numerals.

is a thermal relay, consisting of a heater part and contacts.

PBl, PB is a push button switch, R11R11
1R31R4 is a relay, T1+T! It is a 2-digit timer.

When the working time is set with timer T1 and push button switch PB is turned on, relay R□ is turned on and MC is turned on.
When □ is on, motor M7 rotates and starts milling.

When the time set by the timer T1 comes, the contact T0 turns on, turning on the relay R2 fully, and at the same time setting the timer T2 and operating the solenoid SQL. When the time set by the timer T2 has passed, the contact T2 is turned off and the relays R□ and R2 are demagnetized.

As a result, SOL and MC□ are turned off, and motor M
, stop.

On the other hand, if the number of grains in the hopper 1 decreases before the time set by the timer T1 has elapsed, the detector S1 is turned on. This turns on relay R3 and solenoid S.
OL←Isu≠-di→Sai→Hpa+= and MC are also turned on, closing the shutter and operating the motor M2. At this time as well, the timer T2 is activated, and after a predetermined period of time, the contact T2 is turned off and the motor M1 is stopped. Motor M
When the grains enter the hopper by the operation of 2 and the a contact of the switch S is turned off, the b contact of the switch S1 is turned on, so that the motor M operates again. When the hopper is full of grain, switch S2 is turned off, turning off relay R3 and stopping motor M2'. Whether the restarted motor M1 is caused by the timer T0 or not, the switch S
1, it is stopped by timer T2.

As explained in detail above, the present invention consists of a detector installed in the hopper and a device that controls the shutter and motor based on the signal from the detector, so when the timer is set and the button is pressed, Rice milling work can be performed automatically for a predetermined period of time with just one step, resulting in labor savings. Furthermore, since the rice milling device is controlled in conjunction with the operation of the switch of the grain swallowing section of the rice milling machine, the motor can operate smoothly.
