に関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an automatic control device for a rice hulling sorting device,
More specifically, the present invention relates to an improvement of a roll-to-roll adjustment device when the amount of supply to the hulling section is reduced in a de-sorting device that is integrally configured with a hulling section and a swinging type paddy/brown rice sorting section.

The technique of controlling the distance between a pair of roll-offs by the load value of the electric motor that drives the roll-offs has been known for a long time.
This is a technique disclosed in Japanese Patent Publication No. 66101 and Japanese Patent Publication No. 47-25420. In addition, as an improvement of the automatic control device during derolling, Japanese Patent Application Laid-open No. 55-99347 describes
When the raw material for derolling is not supplied, the load on the main motor decreases and the distance between derolling narrows, resulting in an accident where the unrolled parts come into contact with each other and wear out. A technique is disclosed in which the adjustment of the distance between the rolls is not performed when the adjustment is not made.

However, the conventional method was limited to simple load control for derolling, and no consideration was given to fluctuations in flow rate caused by the interlocking of the huller and the sorting machine in the subsequent process. For this reason, if control is performed to reduce the amount of supply to the sorter in the post-process and the amount of supply to derolling is reduced,
The load on the electric motor that drives the derolling is also reduced, and the derolling interval is narrowed by the derolling interval control, which applies strong pressure to the supplied raw material paddy, which causes the brown rice to shift or break into granules. It was hot.

である。 The present invention was made for the purpose of solving the above-mentioned problems, and is designed to stop the adjustment between derolling when the amount of supply to the derolling section fluctuates, especially when the amount of supply decreases below the lower limit set amount. This is what I did.

In order to solve the above-mentioned problems, the present invention provides a rice husk wind-selecting chamber in the lower part of the de-rolling chamber in which a supply hopper is mounted and a pair of de-rolls driven by a main motor. The mixed grains of paddy and brown rice discharged from the chamber are supplied to a swing sorting board by a grain lifting machine and a grain tank installed on the discharge side of the machine so as to be able to move up and down. In the de-sorting device which uses a motion type to sort into three types: brown rice, mixed grains of paddy and brown rice, and paddy, the grain tank moves downward and downward in response to increases and decreases in the mixed grains of paddy and brown rice inside it, respectively. The grain tank and the flow rate control valve are interlocked and connected so that when the grain tank and the flow rate control valve are moved upward, the opening degree of the flow rate control valve provided in the supply section of the supply hopper is adjusted to small and large respectively. An opening detector for detecting the minimum opening position of the flow rate control valve is provided in connection with the flow rate control valve,
a setting device that sets an upper limit value and a lower limit value of the load in the output circuit of the opening degree detector and in the control circuit of the reversible rotary motor that adjusts the distance between the pair of derolling in relation to the load of the main motor; and the output side of
A technical measure was taken to connect the forward and reverse rotation relays of the reversible rotary motor through an AND circuit.

With the above configuration, more than 80% of the raw material paddy supplied to the supply hopper passes through the derolling section which is initialized and controlled by the load of the electric motor, and is de-rolled in the rice husk winding room. The rice husks are removed from the grains, and the mixed grains of paddy and brown rice are transferred to a grain tank via a grain frying machine, and then fed at a constant flow rate to a vibrating sorting board. The mixed grains of paddy/brown rice are gradually sorted into three types: brown rice, mixed grains of paddy/brown rice, and paddy by the shaking motion of a vibrating sorting board. Then, the brown rice is transferred to the next process, the paddy/brown rice mixed grains are returned to the grain tank via the grain lifting machine, and the paddy is transferred to the previous process for unrolling.

を続行する。 Here, when the amount of mixed grains of paddy and brown rice in the grain tank increases, the tank moves downward due to its own weight, and in conjunction with this, the opening degree of the flow rate control valve of the supply hopper decreases, and the amount of supply to the de-rolling is reduced. decrease, and the flow balance is maintained. However, when the amount of mixed grains of paddy and brown rice in the grain tank increases extremely, the opening degree of the flow control valve becomes narrower, and the supply to derolling is almost no longer performed, reducing the load on the main motor. The signal from the opening detector that detects the position causes the reversible rotary motor to stop adjusting the distance between rolls and continue the work without the rolls coming too close.

〓を正常に調節することができる。 During operation, the gap between derolling 3 and 4 becomes too narrow, causing the load current of the main motor 50 to drop to the upper limit value setting unit 5.
When the set value of 7 is exceeded, the setter 55 side issues an output signal, and conversely, when the gap becomes too wide and the load current becomes smaller than the set value of the lower limit value setting section 58, the setter 56 side outputs an output signal. Each signal is input to the logic (AND) circuit 59 or 60, and the matching signal from the AND circuit 61 causes the reversible rotary motor 37 for adjustment to rotate forward or backward, and the rotation causes The arm lever 28 moves forward or backward through the rod 31, and the derolling period can always be adjusted normally.

る場合がある。 In the sorting operation step, if the number of grains in the supply hopper 11 decreases to the lower limit flow rate, that is, the light receiving element 41 of the photoelectric device 42 no longer receives the reflected light from the grains, or if the opening/closing shutter 43 is closed and the proximity switch 44 issues a signal, the L signal is input to the logic (AND) circuit 59 or 60 via the AND circuit 61 to stop the operation of the reversible motor 37, and The area between the rolls 3 and 4 is locked in the same state, and wear of the rolls 3 and 4 and tearing of the brown rice are prevented. Further, when the flow rate control valve 13 moves upward and the proximity switch 47 serving as an opening detector for detecting the lower limit flow rate position issues a signal (i.e.,
When the grain tank 9 is almost full, the space between the rolls 3 and 4 is fixed in the same state as before to prevent roll abrasion and tearing of the brown rice. Ru. The position of the proximity switch 47 may be adjusted as appropriate.

According to the automatic control device for the de-sorting device of the present invention, it is configured so that the adjustment between rolls due to the load of the main motor can be stopped when the raw material flow rate fluctuates between the de-sorting section and the paddy/brown rice sorting section. , even when the amount of supply to the derolling stage is extremely reduced, the derolling interval can be maintained appropriately.
Stable unrolling work can be achieved without causing damage such as lacerations (skin abrasion) or crushing to unrolled brown rice, and by preventing unnecessary wear of unrolling.
