Next, the control contents of the CPU 25 will be described. First, the automatic / manual switch 30 is selected on the automatic side, and the run / stop switch 43 is operated on the run side. Then, the main motor 44 is turned on to drive the rotating parts of the paddy hull sorting machine. Next, the initial gap setting control for setting the initial gap between the hulling rolls 3 and 3 is performed. A roll gap opening command signal from the CPU 25 is output to the roll gap adjusting motor 45, and the roll gap adjusting means 24 is driven to open for a predetermined time.
When the clearance between the hulling rolls 3 is adjusted and the load current sensor 31 detects the non-contact state of the hulling roll in which the detected load current value does not change, the opening adjustment is stopped. Then,
A close command signal for the roll gap is output, the roll gap is closed and adjusted, and the load current sensor 32 detects an increase in the load current value.
When the slight contact between the hulling rolls 3 and 3 is confirmed, the closing adjustment is stopped. Then, an opening command signal for the roll gap is output, and the roll gap adjusting motor 45 is opened for a predetermined time.
The adjustment setting is made to a predetermined initial gap (for example, 1 mm). Next, the shutter opening initial setting control for adjusting the initial opening of the paddy supply adjusting valve 39a is performed. An open command signal is output from the CPU 25 to the shutter opening adjustment motor 46,
Set the paddy supply control valve 39a to a predetermined valve opening (for example, 10 mm)
The initial opening is set so that the hulling work is started. Next, a valve opening adjustment command signal for adjusting the supply amount adjustment setting position of a paddy supply adjusting lever (not shown) is output, and the paddy supply adjusting valve 39a is changed and adjusted to a position corresponding to the set efficiency valve opening. The roll gap is adjusted based on the reference load current value corresponding to the set efficiency. Next, the paddy supply control valve 39a and the roll gap are not adjusted, and the paddy supply control valve 39a is kept in a fixed state to continue the paddy hulling operation for a predetermined time.
Then, when the detected load current value of the main motor 44 reaches a stable hulling work state, the process shifts to the roll clearance control based on the next load current value reference. Next, the roll gap control based on the load current value will be described. The detected load current value of the load current sensor 32 is the control unit 25.
And the control reference load current value is compared with the detected load current value. If the detected load current value is higher (or lower) than the control reference load current value, the roll gap adjusting motor 4
An open (or close) command signal is output to 5, and the gap between the hulling rolls 3, 3 is adjusted to a predetermined amount on the open side (or closed side), and the detected load current value returns to the control reference load current value. Planned. If the detected load current value is within the range of the control reference load current value, the control command signal is not issued and the hulling operation is performed while maintaining the roll gap as it is. In addition,
Instead of the roll clearance control based on the load current value reference, the hull roll clearance may be controlled based on the removal rate reference. Next, the system setting that is performed when the product is manufactured will be described.

This system setting is such that while the operation / stop switch 43 is stopped, any two switches in the switch group are operated, for example, the display changeover switch 31 of the control panel 54 is turned on, and the automatic / manual switch 30 is set. It is started by turning on. In connection with the selection of the system setting, the function of the switch group is converted, and, for example, the removal rate upper switch 26 or the removal rate lower switch 2
When 7 is turned on, system setting items such as model setting, sensor / actuator check function, overload current value rate correction, scattering position adjustment correction of the rotary selection cylinder 11, original power supply voltage correction, load current value correction The above items are switched in ascending order or descending order, and a predetermined item is selected and started.

Next, the model setting mode is changed to the control flow shown in FIG.
It will be described based on. When the removal rate increase switch 26 is pressed while the display changeover switch 31 is in the ON state, an initial value display of the model (for example, P50) is displayed on the display tube 49, and then the removal rate increase switch 26 is also pressed. Then, the next model display, for example, P40, P30, and P25 is sequentially switched to select the model to be set. Next, when the automatic / manual switch 30 is pressed, the selected model is determined, the model is set and stored in the EEPROM 57, and the display tube 49 returns to the normal display.

Based on this setting type, various control reference values of the type of the automatic control device are selected, and during automatic control, control such as roll gap control based on the load current value is performed based on this. It Also, if the model has already been set, in the process of "Display initial value",
The setting model is first displayed, and the operator confirms the setting model and presses the display changeover switch 31 to terminate the model setting mode and shift to the normal display.

Further, when the setting type is changed from the large type to the medium type in the type setting mode, for example, the breaker capacity data of the previously set type and the breaker capacity of the overload reference current value are compared. The load factor data is erased, and these control reference values are newly input by the operator, or the control data are automatically changed and set in connection with the model change. It may be configured. With this configuration, it is possible to prevent a problem such as hunting of the roll clearance adjustment caused by remaining data such as the previous overload reference current value. Next, the open setting time setting mode of the hulling roll of the system setting will be described with reference to the control flow of FIG.

The initial clearance of the hulling roll is set by a. Open adjustment to confirm roll gap separation, b. B
Closed adjustment to make a slight contact between the gaps, c. The setting is made by adjusting the opening of the roll gap for setting the initial gap. In order to share control of a plurality of types in the control unit 25 having a single configuration, the above-mentioned “c. It is intended to selectively set the "opening time of the gap".

If, for example, the removal rate increasing switch 26 is pressed while the automatic / manual switch 30 is being pressed, an initial value, for example, "5SEC" is displayed on the display tube 49.
When the removal rate upper switch 26 is turned on, a plurality of opening adjustment times, that is, 6SEC, 7SEC, 8SEC, 3SE
The display is sequentially switched to C, 4SEC, etc., and the opening adjustment time that matches the model is selected. Next, when the automatic / manual switch 30 is pressed, the time setting mode for the hull roll gap is completed, and when the automatic / manual switch 30 is then pressed, the selected opening adjustment time is determined. hand,
The open adjustment time corresponding to the model is set and stored in the EEPROM 57, and the display tube 49 returns to the normal display.

Incidentally, instead of the display on the display tube 49, a plurality of initial gaps are sequentially displayed on the 7 segments of the cylindrical rotation speed display device 50 by turning on the removal rate increasing switch 26, and the setting mode is completed. Relatedly, the configuration may be selected and set as described above. If the opening adjustment time has already been set, the opening adjustment time corresponding to the setting model is displayed first in the process of "displaying the initial value", and the operator sets the setting model. After confirming and pressing the display changeover switch 31, the opening adjustment time setting mode for the hull roll gap is set.
The display is terminated and the display is shifted to the normal display.

With this construction, the initial gap can be set according to the size and type of paddy and the type of paddy, and the padding can be carried out at an appropriate removal rate to improve the paddy efficiency. Next, the load factor setting mode at the time of contact with the hull rolling will be described based on the control flow of FIG. At the time of setting the initial clearance of the roll clearance, the "fine contact of the roll clearance when the load current value increases by a predetermined amount" is determined, and this fine contact determination depends on the size of the model. However, it is necessary to select the one that matches the relevant model from a plurality of reference values.

When the display changeover switch 31 is pressed while the automatic / manual switch 30 is being pressed, an initial value of the load factor, for example, "no-load current value + 1 ampere" is displayed on the display tube 49. It Then, by turning on the switch 26 for removing the removal rate, a plurality of load rates, for example, 1.5 amp, 2.0 amp,
Is added, or the load factor of the model is selected by sequentially switching to the display of the load factor for multiplying the no-load current value by 1.18 or 1.25.

Next, when the automatic / manual switch 30 is pressed, this control ends, the selected load factor is selectively determined and stored in the EEPROM 57 as the load factor corresponding to the relevant model, and the display tube 49 is Return to normal display.
When the load factor is already set, the load factor corresponding to the setting model is first displayed in the process of "displaying the initial value", and the operator sets the load factor of the setting model. When the display changeover switch 31 is pressed after confirming the setting, the load factor setting mode of the hull roll gap is completed and the normal display is set.

Next, the time setting mode for shifting from the initial hulling work set by the system to the roll clearance control based on the load current value will be described with reference to the flow chart of FIG. As described above, the initial clearance setting of the paddy roll and the initial opening setting of the paddy supply control valve 39a are completed, and the opening adjustment corresponding to the set efficiency of the paddy supply control valve 39a, and this efficiency setting. The roll clearance is adjusted according to the corresponding load current value reference. Then, the paddy supply control valve 39a and the paddy roll gap are not adjusted, and in a fixed state (the control command signal for roll gap adjustment is not output even if the detected load current value is changed). Continue the hulling work for an hour, and after a predetermined time when the hulling work is stable,
The control shifts to the roll clearance control based on the load current value.

However, the transition time is selected to be long or short in accordance with a plurality of large and small types or according to the kind of paddy to be hulled. When, for example, the removal rate lowering switch 27 is turned on while the automatic / manual switch 30 is still pressed, an initial value of the transition time, for example, 5 minutes is displayed on the display tube 49. Then, by turning on the removal rate lowering switch 27, the transition time is selected by sequentially switching to a plurality of transition times, for example, 10 minutes, 15 minutes, 20 minutes, 25 minutes, 30 minutes. Next, when the automatic / manual switch 30 is pressed, this control ends, and the selected transition time is selected and set, and the EE
The transition time corresponding to the model is stored in the PROM 57, and the display tube 49 is returned to the normal display.

When the transition time has already been set, the transition time corresponding to the setting model is displayed first in the process of "displaying the initial value", and the operator sets the setting model. When the display changeover switch 31 is pressed and the display changeover switch 31 is pressed, the load current value control transition time setting mode is completed and the normal display is selected. Since it is configured in this way, the transition time can be set according to the wear condition of the hulling roll depending on the type of large or small or the type of paddy, etc., and the uneven wear of the hulling roll is prevented, and the proper removal rate is obtained. Can hull and improve efficiency.

When executing the above system setting,
When the operating states of a plurality of modes are displayed on the LED display device 52a of the control panel 54 by lighting different LEDs, the operator can visually recognize the execution mode and the setting work is stable. To do. 10. Next, the maximum load factor setting mode for setting the overload current value for breaker drop will be described with reference to FIG.

While the display changeover switch 31 is still pressed,
For example, when the removal rate lowering switch 27 is turned on, the display tube 4
9, the initial value of the maximum load factor, for example, the breaker capacity ×
The display of 0.95 is made. Next, by turning ON the removal rate lowering switch 27, a plurality of maximum load rates, for example, 1.05 times, 1.1 times, 1.15 times the breaker capacity are added.
The maximum load factor display is sequentially switched to the maximum load factor display of double, 0.85, 0.90, etc. Next, when the automatic / manual switch 30 is pressed, this control ends, and the selected maximum load factor is selectively set, and the EEPRO is set.
The maximum load factor corresponding to the model is stored in M57, and then the display tube 49 returns to the normal display.

When the maximum load factor has already been set, the maximum load factor corresponding to the setting model is first displayed in the process of "displaying the initial value", and the operator is the operator. By confirming the setting of the maximum load factor of the setting type and pressing the display changeover switch 31, the setting mode of the overload current value is completed and the normal display is set. 11. Next, the prevention of erroneous operation during the above various system settings will be described.

When the run / stop switch 43 is turned on during the above-mentioned system setting operation, the system setting is interrupted, and the above-mentioned initial clearance setting control of the hulling roll is carried out.
Next, the control process is sequentially shifted to the next control process of the automatic control operation,
Hulling work is started. In the conventional device, in such a case, the system setting is stopped, "Incorrect operation" is displayed on the display tube, and then "System setting is completed,
The message "Please turn on the operation switch" was displayed, but as mentioned above, the operation can be started immediately and the operation becomes easy. 12. Next, the data confirmation mode will be described.

This mode is intended to easily check the data used for the automatic control operation of hull sorting. The operation method for data confirmation is the run / stop switch 43.
When the machine is stopped on the stop side, the paddy supply control valve 3
9a is opened, and the display changeover switch 31, which is one of a plurality of switch groups, remains ON,
By turning on the manual selector switch 30,
Is selected.

The data that can be confirmed in this mode are, for example, jumper wire settings (models are switched by the short cut state of a plurality of jumper wires) and model type settings. , The maximum load current value rate, the roll gap opening time of the roll gap initial setting, the transition time from the roll gap fixed hull operation to the roll gap automatic control operation, and the hull roll Load current ratio to no-load current value to judge contact,
Control ratio of the initial opening of the paddy supply control valve 39a (the increase value of the load current value when the valve opening is set by a predetermined amount), the upper limit and the lower limit of the opening of the paddy supply control valve 39a (the upper limit of the opening) Is exceeded or becomes narrower than the lower limit of the opening, the roll clearance control based on the load current value is interrupted.), And the paddy supply control valve 3
9a valve opening correction value (increase / decrease correction value with respect to the initial opening),
Frequency difference of breaker capacity (table created from relationship between power supply voltage, frequency and load current value), paddy supply control valve 3
9a is a valve opening origin or the like.

By turning on the display changeover switch 31, the data can be sequentially displayed and confirmed on the seven segments of the cylindrical rotation speed display device 50, and the LED display device 52 is turned on every time the data display is switched. , Switching of data display can be confirmed. Further, when the control data is desired to be changed, the data displayed in the 7 segment of the cylindrical rotation speed display device 50 is pushed by, for example, the removal rate upper switch 26 or the removal rate lower switch 27. The data can be increased / decreased and corrected, and the operator confirms that the data display has been corrected, and when the display changeover switch 31 is pressed,
The previous data is erased and the modified data is stored in the EEPROM.
The data is registered in 57 and the next data is switched and displayed. If you press the automatic / manual switch 30,
Do ends.

With this configuration, the control data can be easily confirmed and the data can be easily corrected. Next, the operation of FIG. 1 will be described. Paddy hopper 2
