The arrangement relationship with a will be described. While the brown rice partition plate 18 is supported by the machine frame so as to be movable and adjustable, a partition plate marker 18a is extended from the brown rice partition plate 18 to the swing sorting plate 15 side to facilitate confirmation of the partition position on the plate surface. The partition plate marker 18a is disposed below the lower end of the rice / brown rice discrimination sensor 30. Therefore, even if the brown rice partition plate 18 is moved to the uppermost swing position of the swing sorting plate 15 by manual adjustment, it is possible to prevent a problem such as collision.

The rice / brown rice discrimination sensor 30 is constructed as follows in this embodiment. An electromagnetic wave including a moisture absorption wavelength band and a reference wavelength band that is not absorbed by moisture is applied to the grain from a light emitting portion constituted by an incandescent lamp, and reflected light (or transmitted light) from the grain is used for the moisture absorption wavelength band. The light is received by a detection element, which is an optical filter section, via a band-pass filter. The detection element converts the light into a large or small voltage value in accordance with the amount of received light, and sends the converted voltage to a control section 41 built in the CPU. Also,
The reference wavelength band reflected by the bandpass filter is sent to the reference wavelength band detection element unit via the filter, converted into a voltage value, and sent to the control unit 41. Thus, the control unit 41

This is a configuration for determining the type of brown rice.

As shown in FIG. 3, the control unit 41 having a built-in CPU includes a rice / brown rice discrimination sensor 30, a partition plate origin switch (upward swinging) 33, and a partition plate origin switch (upward swinging).
4, a sensor origin switch (upward swing) 35, a sensor origin switch (upward swing) 36, a load current sensor 44 for detecting a load current value of the main motor 42, and an operation switch 45 are connected via an input interface. doing.

The control unit 41 includes a partition plate adjusting motor 29, a sensor adjusting motor 32, and a main motor 42 via an output interface (not shown) and a driving circuit.
Each one is connected. Next, the control of the brown rice partition plate by the control unit 41 will be described. When this control is started,
The brown rice discrimination sensor 30 moves to the lower side 15d by a predetermined distance from the uppermost upper side 15c position, stops for a predetermined time, and detects the voltage value of the grain. Next, the number of detected rice grains for a predetermined time is compared with the control reference value, and when the number of detected rice grains is large (or small), the rice / brown rice discrimination sensor 30 is swung upward 15c.
(Or the lower side 15d) while moving a predetermined distance
The operation of detecting the boundary of brown rice is continued, and the position where the number of detected rice grains reaches the reference value is set as the detection position of the distribution boundary of rice and brown rice. Next, based on the boundary detection position of the paddy / brown rice, the partition position of the brown rice partition plate 4 is calculated, the brown rice partition plate 18 is moved to the partition position, and the brown rice is partitioned by the brown rice partition plate 18 at a position where paddy is not mixed. Take it out of the machine.

Next, a description will be given, with reference to FIG. At the end of the operation of the oscillating sorting device, for example, the brown rice partition plate 18 is moved upward by a predetermined distance from the partitioning position of the normal operation in relation to the distribution kernels moving upward due to the decrease in sorted kernels. Then, the brown rice was taken out of the partitioning machine at a position where no paddy was mixed, and then the grains circulating in the machine were returned to the paddy rolls 7, 7 while being padded and detected by the paddy / brown rice discrimination sensor 30. The brown rice is taken out of the machine while controlling the movement of the brown rice partition plate 18 to the partition position related to the boundary position between the paddy and brown rice, and the brown rice partition plate 18 is removed.
Moves to the predetermined swinging up position, it is determined that the residual kernel processing is completed, and processing such as stopping the motor is performed.

In this embodiment, the shift from the normal operation to the residual grain processing step is determined based on the detection content of the paddy / brown rice discrimination sensor 30. When the supply of the mixed rice to the rocking sorting plate 15 is lost, the mixed rice on the plate surface decreases and moves to the rocking side, and the boundary position of the paddy / brown rice also moves to the rocking side in relation to the plate surface. In the case of the mixed rice flowing rapidly to the discharge side, the mixed rice moves up and down in a short time. In this embodiment, utilizing such a phenomenon, the shift to the residual grain processing step at the end of the work is determined by the paddy / brown rice discrimination sensor 30 to try to make effective use of the paddy / brown rice discrimination sensor 30. Things.

Next, the determination method will be described with reference to FIG. When this control is started, a timer function for a predetermined time is set and time measurement is started, and it is determined whether or not time is up. When the time is being measured, the paddy / brown rice discriminating sensor 30 detects the number of paddy grains for detecting the boundary position of the paddy / brown rice, and determines whether or not there is an interrupt input of the paddy detection data. When there is an interrupt input, it is determined that it is a normal sorting operation, and the clocking is continued.When there is no interrupt input, it is determined that there is no kernel at the detection point, and it is determined that the process is to shift to the residual kernel processing step. ,
When there is an interrupt input, it is determined that the work is normal work, and the clocking is continued.

When the counting of the timer function is completed, it is determined whether or not the number of rice grains detected by the rice / brown rice discrimination sensor 30 is appropriate. When the number of detected paddy grains is appropriate compared to the paddy / brown rice boundary reference grain count, reset the continuous counter, and
If the number of detected rice grains is not appropriate, proceed to the residual grain processing determination step, compare the number of detected rice grains with the standard number of rice grains to determine the boundary position between rice and brown rice, Is determined, and when the number of detected rice grains is small, the continuous counter function is reset, and the rice / brown rice discrimination sensor 30 is moved a predetermined distance to the rocking side.

When the number of detected grains is larger than the number of grains for judging the boundary between rice and brown rice, the continuous counter is set to 1
And the paddy / brown rice discrimination sensor 30 is moved upward by a predetermined distance, and then it is determined whether or not the continuous counter has reached the set reference number. If the set reference number has not been reached, the routine returns. Is reached, it is determined that the process proceeds to the residual kernel processing step, and the continuous counter is reset.

In this embodiment, the determination is made by moving the paddle / brown rice discriminating sensor 30 upward and downward at least a predetermined number of times when the paddy / brown rice discriminating sensor 30 detects the boundary between the paddy / brown rice. The configuration may be such that the determination is made based on the upward movement. As described above, it is possible to determine the shift to the residual kernel processing step at the end of the operation by using the paddy / brown rice discrimination sensor 30 without using a special sensor, thereby achieving cost reduction. it can.

Next, another embodiment of the residual grain processing control at the end of the operation will be described with reference to FIG. When this control is started, for example, it is determined whether or not the process has shifted to the residual kernel processing step at the end of the work, based on whether or not the paddy / brown rice discrimination sensor 30 has continuously moved upward for a predetermined time. When it is determined to shift to the residual grain processing step, the current partition position (LP) of the brown rice partition plate 18 is read out, and a predetermined residual kernel processing reference partition position [or a predetermined formula (LP / a) is calculated from the current partition position. , A is a constant].
Then, a command to move the brown rice partition plate 18 is issued to determine whether or not the rice has moved to the reference partition position, and upon reaching the reference position, the brown rice partition plate 18 is stopped.

Next, the paddy / brown rice boundary position is detected by the paddy / brown rice discrimination sensor 30, and the detected paddy / brown rice boundary position of the paddy / brown rice discrimination sensor 30 and the partition position of the brown rice partition plate 18 are in a predetermined relational expression. It is determined whether the condition is appropriate or not, and if it is within the range of the relational expression, the same normal brown rice partition plate control as described above is executed, and the partition related to the rice / brown rice boundary detection position of the rice / brown rice discrimination sensor 30 is detected. Move and adjust the brown rice partition plate 18 to the position.

During the control of the partitioning position of the brown rice partitioning plate 18, in order to improve efficiency, the partitioning position is positioned slightly above the boundary between the rice and brown rice and the operation is performed. When the supply of grains to the rocking sorter plate 15 decreases, the grains on the plate move quickly to the rocking upper side. Then
In the method in which the sensor detects the boundary position between the paddy and brown rice and issues a command to move to the swinging side, and the brown rice partition plate 18 is moved by the rotation of the screw rod of the partition plate movement adjusting means 28, the rapid movement of the grain Cannot be followed, and a problem occurs that rice is mixed into brown rice.

However, in this embodiment, when the shift to the residual grain processing step is detected, the brown rice partition plate 18 is moved upward by a predetermined distance from the normal partition position to reduce the width of the brown rice partition. It is possible to prevent the paddy from being mixed into the brown rice during the transition to the grain processing step, and to improve the accuracy of controlling the brown rice partition plate. Next, another embodiment of the residual grain processing control shown in FIG. 7 will be described.

In this embodiment, during the residual kernel processing step,
When the paddy / brown rice discriminating sensor 30 detects the boundary position of the paddy / brown rice, if it moves to the lower side continuously for a predetermined number of times, it is determined that the work has returned to the normal operation, and the residual grain processing control is to be released. Is what you do. The control contents will be described with reference to FIG. When this control is started, a timer function for a predetermined time is set to start timing, and it is determined whether or not the time is up.
Count the number of paddy grains detected as 0 for the boundary between paddy and brown rice. When the counting of the timer function ends, the number of detected rice grains is compared with the number of reference grains to determine whether or not the count is appropriate. If the count is appropriate, the continuous counter is reset.

If the number of detected rice grains is not appropriate,
The number of detected rice grains is compared with the standard number of rice grains for judging the boundary between rice and brown rice or a separately determined reference number of rice grains, and the number of detected rice grains is determined.If the number of detected rice grains is large, the continuous counter is reset. Then, the paddy / brown rice discrimination sensor 30 is moved a predetermined distance upward. When the number of detected paddy grains is small, the continuous counter is counted as 1 and the paddle / brown rice discrimination sensor 30 is moved downward by a predetermined distance, and then it is determined whether or not the continuous counter has reached the set value. When the set value is not reached, the process returns. When the set value is reached, it is determined that the operation has returned to the normal operation from the transition to the residual kernel processing step, and the continuous counter is reset.

As described above, the rocking sorter 1 uses the rice / brown rice discrimination sensor 30 without using a special sensor.
5. From the change in the grain distribution state on 5 above, it is possible to cancel the residual grain processing step at the end of the work and return to the normal work,
Highly accurate brown rice partition plate control can be performed while reducing costs. Next, an embodiment shown in FIG. 8 will be described.

This embodiment is a mode in which the operator stops the main motor after the residual grain processing, or terminates the operation before or during the operation, or the main motor after the residual kernel processing. A mode in which driving is continued,
The control unit 41 is provided with a stop mode switch capable of selecting a mode in which the main motor is stopped without performing a residual processing step.

The control will be described with reference to FIG. When this control is started, the mode of the stop mode switch is read, and it is determined whether or not the main motor 42 is stopped after performing the residual grain processing step. It is determined whether or not the kernel processing is completed, and when the residual kernel processing is completed, the main motor 42 is stopped. Also,
In the case of a mode in which the main motor 42 is terminated without stopping after the residual kernel processing, the driving of the main motor 42 is continued for a predetermined time after the residual processing, and then stopped.

In this embodiment, since the operation end mode can be selected by a switch, continuous operation is possible by re-inputting the paddy to the hulling roll, and the main motor 42 is also stopped after the residual kernel processing. Therefore, power saving and improvement of machine durability can be achieved. Next, paddy
In controlling the brown rice partition plate for detecting the boundary position of the unpolished rice and brown rice with the brown rice discriminating sensor 30 and moving and adjusting the brown rice partition plate 18 to the relevant partition position, the partition position of the brown rice partition plate 18 is changed by the swing sorting plate 15. An embodiment in which the swing center is set will be described.

In issuing a movement command for the brown rice partition plate 18 from the control unit 41, when the movement position is calculated, a predetermined formula (for example, y = aX + b, a and b are constants, X is the calculated movement of the brown rice partition plate 18) Position) or a predetermined table to determine a correction movement position to be a swing center and issue a movement command. Since the brown rice partition plate 18 is fixed to the outer frame with respect to the swing sorting plate 15 that swings in the lateral direction, the partition position of the brown rice partition plate 18 is, for example, within a swing width of 20 mm. Change.

In this embodiment, as described above, the position of the brown rice partition plate 18 is set to the partitioning position with reference to the center of the swing width.
The partition position becomes accurate, and the data processing of the automatic control can be simplified. In addition, the paddy / brown rice discrimination sensor 30 is swung
By moving to the swing center position of No. 5 and detecting the boundary position between the paddy and brown rice, the data processing can be similarly simplified.

Next, the embodiment shown in FIG. 9 will be described. In order to accurately determine the transition to the residual grain processing step in the control of the partitioning position of the brown rice partitioning plate 18, a poor machine adjustment (for example, It is accurately determined whether the adjustment is due to poor adjustment of the lateral inclination angle of the surface, poor removal rate due to poor adjustment of the roll gap of the hulling rolls, or the loss of the hulling supply to the hulling rolls 7, 7. Then, it is intended to improve the accuracy of the processing of the residual kernel.

When this control starts, the rice / brown rice discrimination sensor 30 moves from the upper side to the lower side to determine whether or not the reference voltage value for determining the rice / brown rice has been calculated.
The determination may be made as to whether or not the rice / brown rice discrimination sensor 30 has detected the boundary position between the rice / brown rice and whether the brown rice partition plate 18 has been moved to the partition position by automatic adjustment. ). When the reference voltage value is calculated, for example, a grain sensor (not shown in the drawing) indicates whether or not the paddy has been stuck into the paddy hopper 6. The closing of the paddy supply control valve may be detected by the paddy supply sensor. ), And the presence or absence of the supply of the rice to the hulling rolls 7, 7 is determined. Thus, when there is no paddy supply, the paddle / brown rice discrimination sensor 30 determines whether or not it has reached the pivoting origin position by the sensor origin switch (pivoting) 35,
When moving to the swinging origin position, it is determined that the normal operation has been shifted to the residual kernel processing.

In order to control the partitioning of the brown rice partition plate 18 from the relationship between the preset rice / brown rice discrimination sensor 30 and the partition position of the brown rice partition plate 18, the mixing supplied to the swing sorting plate 15 is performed. As the amount of rice decreases, the boundary position of the paddy / brown rice moves upwards and the brown rice is taken out of the machine until the paddy / brown rice discrimination sensor 30 or the brown rice partition plate 18 moves to a predetermined reference position, and thereafter Moves the brown rice partitioning plate 18 to the uppermost position, returns the grains discharged from the rocking sorting plate 15 to the hulling rolls 7, 7 and grinds the rice for a predetermined time. When the hulling is completed, the brown rice partitioning is performed. The plate 18 is moved to the lower side to remove the brown rice outside the machine, and the residual grain is treated.

However, such a change in the state of the sorted kernels does not occur only at the end of the work, but the swinging sorter 1
5 may occur due to poor adjustment of the lateral inclination angle, etc., and there is a problem that it is not possible to accurately determine the shift to the residual kernel processing only with the detection data of the rice / brown rice discrimination sensor 30. However, as described above, since the transition to the residual kernel processing is determined based on the detection of the boundary position between the rice and brown rice by the rice / brown rice discrimination sensor 30 and the supply state of the kernel, the determination is accurate and the work efficiency is improved. be able to.
