Description

[Detailed Description of the Invention] (a) Field of Industrial Use The present invention is an automatic device for preventing the paddy from catching the paddy rolls and overflowing the paddy from the transfer section when the paddying machine is operated or stopped. The present invention relates to a control device.

(B) Conventional Technology The conventional technology related to the control of the huller is known. For example, Japanese Utility Model Laid-Open No. 60-132843,
The technique is described in JP-A-57-24648.

(C) Problems to be solved by the invention In the above-mentioned Japanese Utility Model Laid-Open No. 60-132843, the huller is a single piece of hull and it is only the motor that drives the shutter and debarking roll that needs to be controlled. Since the hulling machine has a small processing capacity, even when the motor is stopped and the hulls are accumulated in each part during the hulling, the hulling machine is not likely to be clogged at the next start.

Therefore, as in the case of the plant huller like the present invention,
There was no need to perform complicated control when starting and stopping.

Further, in the grain huller disclosed in Japanese Patent Laid-Open No. 57-24648, a grain elevator, a grain huller, a sorter, a mixed rice elevator,
A drive motor is provided for each unit, such as a grain sorter / brown rice elevator, and the motor is turned on / off in the reverse order at the start and stop of operation according to the setting order.

However, even in this technology, since the elevator and the shutter are not configured to be driven separately and the shutter is not controlled, even if each device is operated or stopped in the order,
Since the shutter is not controlled to be opened and closed, paddy, mixed rice, and brown rice are clogged in the portion, which causes a problem that rotation is impossible in the next operation.

The present invention solves the above problems.

In FIG. 1, the entire structure of the huller will be described.

The huller is composed of three elevators 1, 2, and 3, a main body, and brown rice tanks 11 and 12. 1 is paddy lifter, 2
Is a mixed rice elevator and 3 is a brown rice elevator. The paddy elevator 1 is driven by a paddy lifting motor M2, and paddy hoppers 17 and 17a are arranged at the lower end thereof.

The grain fried by the paddy elevator 1 is put into the roll tank 4. Inside the roll tank 4, a roll tank upper limit switch LS1 and a roll tank lower limit switch LS2 are arranged. A shutter 19 is arranged at the lower end of the roll tank 4, and a solenoid valve SV2 for operating the shutter 19 is configured.

Further, a dewaxing roll 9 is arranged below the shutter 19, and a solenoid valve SV3 for opening the dewaxing roll 9 when the main switch MS is stopped is arranged.

The main body is the dewaxing roll 9, a wind sorting device 10 thereunder, a mixed rice lifting machine 2, a mixed rice tank 5, an oscillating sorting device 6,
It is composed of the particle size selection device 8 and the like, and all the driving parts are driven by the machine motor M3. Therefore, when the machine motor M3 is stopped, the paddy elevator 1 and the brown rice elevator 3
All stop together except.

The mixed rice after de-meshing by the de-meating roll 9 is wind-selected by the air-selecting device 10 and enters the mixed-rice tank 5 from the mixed-rice hopper 15. Next, it is lifted by the mixed rice elevator 2 and enters the mixed rice tank 5. In the mixed rice tank 5, the mixed rice tank upper limit switch LS3 and the mixed rice tank lower limit switch LS are also included.
4 are arranged.

The mixed rice dropped from the mixed rice tank 5 is sorted by the rocking sorting device 6 into three types of paddy, mixed rice and brown rice, and the brown rice enters the grain size sorting device 8 and is grain size sorted by the grain size sorting device 8. Then, from the brown rice hopper 14, through the brown rice elevator 3,
It is sent to brown rice tanks 11 and 12. The brown rice elevator 3 is driven by a brown rice lifting motor M1.

As described above, the grain huller of this embodiment is the brown rice rising motor M1.
It is driven by three motors, a hull rising motor M2 and a machine motor M3.

A tank changeover switch LS7 is arranged in a portion separated from the brown rice elevator 3 and the brown rice tanks 11 and 12, and each brown rice tank 11 and 12 has a brown rice tank upper limit switch LS5.
・ 6 is placed.

The mixed rice sorted by the swing sorting device 6 is returned to the mixed rice tank 5 from the mixed rice hopper 15 a of the mixed rice elevator 2. The paddy sorted by the swing sorting device 6 is returned to the paddy hopper 17a and then to the roll tank 4.

The brown rice tanks 11 and 12 may be provided with two tanks or only one tank depending on the required capacity of the side using the huller. In this case, the tank changeover switch LS7
By setting the mixed rice tank upper limit switch LS3 on the brown rice tank 11 side as it is, the flow chart described later does not need to be changed.

(F) Function of the invention The invention is constructed as described above, and then, as shown in FIG.
The control operation will be described with reference to the flowchart of FIG.

In FIG. 2, according to the flowchart in the state in which FIG. 3 is connected, the judgment is repeated every 20 mm seconds to 40 mm seconds by the command of the clock circuit, following the flowchart. Then, if the determination circuit reaches each determination circuit and if yes and no are in the same state, the same flow is repeated, and if yes and no of the determination circuit changes, the flow path changes and the operation is performed accordingly.

Explain from the start of Fig. 2. When the main switch MS is operated to the stop side, the paddy hopper 1
The solenoid valve SV1 for opening and closing the paddy hopper shutter 18 of No. 7 operates in the closing direction, and the solenoid valve SV2 of the shutter 19 also operates in the closing direction.
The solenoid valve SV3 for opening and closing is operated in the opening direction.

Then, after the set time of the machine motor timer M3T has elapsed, the machine motor M3, the paddy rice rising motor M2, and the brown rice rising motor M1 are stopped.

The main part of the present invention is in the order of the stop operation of the main switch MS described above.

Next, when the main switch MS is turned on to the driving side, first, the brown rice rising motor M1 is driven, the paddy rising motor M2 is driven, the machine motor M3 is driven, and at the same time, the machine motor timer M3T is set. Start it.

Then, turn on / off the roll tank upper limit switch LS1.
Judging FF, roll tank upper limit switch LS1 is ON
That is, when the paddy tank 4 is sufficiently covered with paddy, the indicator lamp 25 is turned on and the solenoid valve SV1 is operated in the closing direction to prevent further paddy from flowing into the roll tank 4. It will stop. Further, the display lamp 22 showing the opening and closing of the paddy hopper shutter 18 is turned off.

On the contrary, when the roll tank upper limit switch LS1 is OFF and there is still a sufficient margin in the roll tank 4, the indicator lamp 25 indicating the fullness of the roll tank 4 is extinguished, and the machine motor timer M3T has not elapsed. In this case, since it is just after the operation, other devices are not operating sufficiently, so the paddy hopper shutter 18 of the paddy hopper 17 is closed by the solenoid valve SV1.

Next, after the set time of the machine motor timer M3T has passed, the paddy hopper shutter 18 of the paddy hopper 17 is opened by the solenoid valve SV1. Then, the display lamp 22 indicating that the paddy hopper shutter 18 is opened is turned on.

Next, the flow proceeds to FIG. 3 to determine whether the upper limit switch LS3 of the mixed rice tank 5 is ON or OFF. When the mixed rice tank upper limit switch LS3 is ON and the mixed rice tank 5 is full, the indicator lamp 27 is turned on because it does not enter any more, the solenoid valve SV2 is closed, and the supply to the debarking roll 9 is performed. It is stopped and the dewaxing roll 9 is also opened.

When the mixed rice tank upper limit switch LS3 is OFF and the amount of mixed rice is small, the display lamp 27 is turned off and ON / OFF of the roll tank lower limit switch LS2 is determined.

Then, it is determined whether the roll tank lower limit switch LS2 of the roll tank 4 is ON or OFF. When the roll tank lower limit switch LS2 is OFF, since the roll tank 4 is empty, the display lamp 26 is turned on, the shutter 19 is closed by the solenoid valve SV2, and the derailing roll 9 is opened by the solenoid valve SV3.
Open up.

When the roll tank lower limit switch LS2 is ON and there is paddy in the roll tank 4, the display lamp 23 is turned on, the shutter 19 is opened, and the debarking roll 9 is closed.

Next, it is judged whether the tank changeover switch LS7 is ON or OFF, and if it is ON, it flows toward the brown rice tank 12,
Next, the upper limit switch LS5 of the brown rice tank 12 is determined, and when the switch is ON, there is no room for the tank, and the alarm buzzer 29 is sounded. Then, the tension pulley is removed by the solenoid valve SV4 to stop the swing sorting device 6.

Similarly, when the tank changeover switch LS7 is OFF, the upper limit switch LS5 of the brown rice tank 11 is judged, and when the brown rice tank 11 is also full, the alarm buzzer 29 is sounded. If the upper limit is not reached, the mixed rice tank lower limit switch LS4 of the mixed rice tank 5 is determined.

When the mixed rice tank lower limit switch LS4 is ON, that is, when the mixed rice tank 5 is empty, the solenoid valve SV4
The oscillating sorting device 6 is stopped by, and when the mixed rice remains to some extent, the oscillating sorting device 6 is driven by the solenoid valve SV4.

2 and 3, the roll tank upper limit switch L
S1 has timer LS1T and roll tank lower limit switch LS
2 has timer LS2T, mixed rice timer upper limit switch LS
3 has timer LS3T, mixed rice tank lower limit switch LS
4 is provided with a tank LS4T, an upper limit switch LS5 of the brown rice tank 11 is provided with a timer LS5T, and a solenoid valve SV2 is provided with a timer SV2T.
It is provided in order to prevent chattering in which the operating portion is repeatedly switched at the N / OFF branch point and the ON / OFF is repeated accordingly. It is configured so that it is not switched to another state while the timer has not elapsed.

As shown in the above flow chart, the ON / OFF of each sensor switch is judged and the paddy hopper shutter 18 and the shutter 19 of the roll tank 4 are opened / closed, the drive of the rocking / sorting device 6 is stopped, and the alarm buzzer is activated. It sounds and performs automatic control. As a result, only the operation of the main switch MS to the driving side is performed, and thereafter, the movement of the sensor switch and the operating solenoid causes the paddy / mixed rice /
By detecting the movement and amount of brown rice, it is possible to automatically perform the perfect hulling work.

Also, when the main switch MS is set to the stop side, the paddy hopper shutter 18 is closed and the shutter 19 is closed,
The debarking roll 9 is opened, and the brown rice rising motor M1, the paddy rising motor M2, and the main motor M3 are stopped after a certain period of time.

Therefore, the operator only operates / stops the main switch MS, and after that, the huller detects the optimum state.

(G) Effect of the Invention Since the present invention is configured as described above, it has the following effects.

Firstly, the present invention separately opens and closes each shutter and debarking roll by a solenoid valve, in addition to a motor for driving each device constituting a huller, and operates the solenoid valve first when stopped and later when operated. By doing so, the clogging of each part could be completely eliminated.

Second, instead of stopping the three motors at once by stopping the main switch MS of the huller as in the conventional case,
First, the paddy hopper shutter 18 of the paddy hopper 17 is closed, the shutter 19 of the roll tank 4 is closed, the flow of the paddy is stopped, and the debarking roll 9 is opened. In that state, only during the machine motor timer M3T, Each motor is maintained in a rotating state to allow a time for finishing the sorting of the grains passing through the inside of the wind sorting device 10, the mixed rice tank 5, the swing sorting device 6 and the grain size sorting device 8. Therefore, even if the machine is stopped after the machine motor timer M3T has elapsed, there will be no residual kernels in each device, and there will be no badly sorted kernels at the beginning of the next restart. Of.

Thirdly, as in the case where the three motors are stopped without opening and closing the shutter as in the conventional case, the paddy remains on the de-sticking roll 9 after the stop, and when the restart is performed, the paddy is bitten. In the jammed state, the dewaxing roll 9 does not rotate and V from the motor
The belt never slips.
