Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides an oscillating sorting device equipped with an oscillating sorting device that oscillates a sorting plate tilted back and forth and left and right to sort the grains on the sorting plate into brown rice and paddy. It's about machines.

The grains that are sorted into brown rice and paddy by a sorting plate are separated and taken out by a dividing plate at the end of the sorting plate, and the position control of the dividing plate is used to control the Alternatively, it is configured to use a grain sensor that detects the mixing ratio of paddy.

However, when the position of the partition plate is controlled only by the grain sensor, there is a large deviation in the operation between the sensor and the partition plate, and the partition plate cannot follow the detection operation of the sensor, resulting in a certain delay. This always results in a hunting phenomenon occurring on the partition plates, and there is a disadvantage that it is impossible to respond accurately and control the partition plates appropriately, especially at the start or end of operation where the grain flow changes rapidly. Ta.

The present invention has been improved in view of the above points, and includes a position sensor for detecting the position of a partition plate that separates and takes out brown rice and paddy, and a grain sensor that outputs brown rice or paddy. By controlling the position of the partition plate using a position sensor and a grain sensor, the poor followability of the partition plate to the grain sensor can be resolved, and the occurrence of hunting phenomena etc. can also be prevented, and the detection operation of the grain sensor can be improved. The present invention aims to provide an oscillating sorting machine that can maintain a constant sorting performance and improve the efficiency of sorting work by appropriately moving the position of the finishing plate based on the following.

Next, automatic control of the brown rice partition plate (9) will be explained with reference to FIG.

The plate (9) is moved to the brown rice side or the coarse side, and when the output of the potentiometer (support) and the output of the sensor (support) are balanced, the drive of the motor Qη is stopped and this detection is performed. The system is configured to constantly control the amount of paddy contained in the mixed rice at each location.

Further, the manual switch 4 to decoy for manual priority forward rotation and reverse rotation is connected to the relay circuit 07), and these switches f411149) are connected to one of the NAND circuits IIA of the flip-flop circuit via the knot circuit -. Then, connect the automatic switch for partition control to the other NAND circuit of the flip-flop circuit via a knot circuit, and connect the output side of the NAND circuit 131 of this flip-flop circuit to the buffer circuit. At the same time, the output side of each NAND circuit extension 1thυ is connected to each automatic and manual indicator lamp block b81, so that when the manual switch (481149) is off and the automatic switch β (to) is on, At this time, the automatic indicator lamp 157) is turned on, the relay unit 4 is energized, the relay switch r42a) is turned on, and the motor Q is turned on.

? ) is energized, the relay switch (45aX47a) is switched to the circuit side (-8f49), and the motor 0η is manually rotated in the forward and reverse directions.

In addition, the tongue tab α was rotated in the normal direction and the partition plate (9) was moved to the maximum movement end on the brown rice side, so that the width σ) on the brown rice side was minimized.
Connect the normally open switch that operates in conjunction with the normally closed switch that operates when
A solenoid η for operating the switching shutter is connected to the pot via a normally closed limit circuit and an operation delay circuit, and ``when the partition plate (9) reaches the maximum movement end on the brown rice side, the solenoid η is activated after a certain period of time. Excite the force until the shutter (1)
The mixed rice outlet (15) is configured to switch from the brown rice outlet f+3) to the mixed rice outlet (15). The switch H is installed on the back side of the guide plate (11) as shown in FIG. +3) so that the mixed rice flows down to the mixed rice discharge port (15) and is turned off when the shutter (1) is switched.

This embodiment is constructed as described above, and now each sorting plate (
3) The grains fed on top after the hulling process have an inclination angle (
During the flow down along β), the angle of inclination decreases due to differences in the stationary position and coefficient of friction, the rocking movement of the sorting plate (3), and the rough sorting surface of the sorting plate (3) surface. Perhaps due to this, there is a paddy layer (B) on the shaking side and a mixed rice layer (C) in the middle area.
are sorted into a state where they are concentrated. This is separated by the partition plate +9) +10+ provided at the end of the flow and taken out respectively, and the position of this brown rice partition plate (9) is controlled by the paddy detection operation of the boundary sensor in the mixed rice layer (C). This is what I did.

In other words, when detecting the difference in light reflection between brown rice and paddy, the reflectance increases in proportion to the amount of mixed paddy.As a result, the amount of paddy contained in the mixed rice at the detection position of the sensor is larger than usual. When the ratio becomes higher than a certain reference value, the detection output of the sensor also increases, causing an output difference between the output of the voltage regulator and the output of the voltage regulator. A signal is output to activate the rotation drive circuit. As a result, the partition plate (9) is moved toward the brown rice side, and the partition σ) on the brown rice side is automatically adjusted to a small value to prevent paddy from entering the brown rice side.

On the other hand, contrary to the above □, if the paddy mixing ratio of this mixed rice is lower than the reference value and the detection output of light reflection by the sensor (36) is also small, the comparator (c) activates the reverse drive circuit decoy. A signal is output, and the partition plate (9) is moved to the coarse side, and the brown rice partition (T) is automatically adjusted to a large size, thereby appropriately increasing the amount of brown rice to be taken out.

Further, when the partition plate (9) reaches the maximum movement end on the brown rice side, the switch is turned off and the drive of the mortar θ motor is stopped, and at the same time the switch 19, which is interlocked with the switch (3S), is turned off. As a result, after a certain period of time, the solenoid (2 forces) is excited, the shutter is switched, and the grains on the brown rice side flow down to the mixed rice discharge port 05, and the brown rice is discharged. This prevents rice mixed with paddy from flowing down to the outlet (13).

In addition, FIGS. 6 and 7 show other deformed structures,
Photoelectric brown rice and photoelectric paddy sensors ((to) It is configured to detect reflected light of the irradiated light.

Then, the other input terminal of the differential amplifier t411, which connects the boundary sensor (G) to one input terminal, is connected to the brown rice and paddy sensor (6υ(()) for setting the level of the output of the differential amplifier. A regulator is connected.

The brown rice sensor (661 is connected to the differential amplifier (buffer circuit 189 to one input terminal of 6η) via the differential amplifier (buffer circuit 189 to one input terminal of 6η), and the paddy sensor (661 is connected to the buffer circuit (7Ill and relay power to the other input terminal of 6η) ) relay switch (
71a), and the reference voltage (Vcc)
The relay ff++ is connected to the output side of a differential amplifier (c) whose input terminals are connected to the buffer circuit -. In addition, the relay (side race Ijichi (7,
:(a) A regulator is provided to control the operation of the relay and the output of the operating amplifier (6η), and the relay is connected to the differential amplifier via a knot circuit (7). (Connect it to the output side of
When the relay ((to) is detecting paddy, the relay (7)
1) is energized to turn on the relay switch (71a) to automatically set the standard composition of the boundary sensor eel based on the light reflection difference detected by the sensor (g) and the brown rice sensor (t). On the other hand, when the paddy sensor (@) does not detect paddy but detects the sorting plate (3) surface due to insufficient supply of unsorted grains, the excitation of the relay circle is canceled and the relay switch ( 71a) is turned off, the relay (74) is energized to turn on the relay switch (78a), and the relay 74 is energized to switch the relay switch (45a) to correct the motor (17). The partition plate (9) is moved to the maximum movement end on the brown rice side.

In the case of this configuration, even under conditions where the material such as the variety and moisture content of unsorted grains changes and the light reflectance thereof changes, the reflectance of the brown rice and paddy after this alteration can be measured by the brown rice and paddy sensor ((
To) ((G)) The boundary sensor (G) is automatically adjusted to have an appropriate reference sensitivity adapted to the material of the grain based on the difference in reflection, and There is no need to adjust the reference sensitivity each time.As a result, the boundary sensor (g) can be adjusted to the partition plate (9) by changing the reflectance due to the material.
The sensor ■ is adjusted to the standard sensitivity that always detects a constant paddy mixture ratio without any inconvenience such as having to control the paddy mixture ratio, and the sensor ■ operates only by changes in reflectance due to changes in the paddy mixture ratio, and the partition plate (9) This is to control the position of the

In addition, when the unsorted grains are insufficiently supplied during operation, or when the sorting is about to end and the paddy sensor (■) detects the sorting plate (3) surface, the grain layer becomes thinner and the grains may shift or become separated. The oscillating movement of the sorting plate (3) and its rough sorting surface cause the rice to be separated entirely on the shaking side, that is, on the unpolished rice side, without causing any floating liquid phenomenon of the paddy, resulting in the inconvenience of poor sorting.
Sign. Therefore, when the paddy sensor (g) detects the plate surface of the sorting plate (3), an output balanced with the reference voltage (Vcc) is output from the paddy sensor (g), and as a result, the relay switch (71a) is turned off. , and relay switch (78a)
is turned on, the relay switch (45a) is replaced, the motor (17) is driven to rotate in the forward direction, and the partition plate (9) is moved to minimize the brown rice side partition (T).

It should be noted that this configuration also provides the same effects as those of the above-mentioned embodiment, and the same components are denoted by the same reference numerals and detailed explanation thereof will be omitted.

As is clear from the above embodiments, the present invention is based on the position of the partition plate (9) that separates and takes out the brown rice and paddy in a swinging sorting device (2) that sorts several grains into brown rice and paddy. The partition plate (9) is equipped with a position sensor (311) and a grain sensor (311) and a grain sensor (311) and a grain sensor (311) and a grain sensor (311) and a grain sensor (311) and a grain sensor (311) and a grain sensor (G) and a grain sensor (G) and a grain sensor (311 and Therefore, the movement of the partition plate (9) is always controlled in a constant manner based on the correlation between the grain sensor and the position sensor.For example, when the grain sensor is used alone, When this happens, the hunting phenomenon of the partition plate (9) caused by poor followability is resolved, and the grain sensor ■((to)(
It is possible to move the partition plate (9) appropriately based on the detection operation of the grain flow, and it is possible to accurately respond to changes in the flow of grains, such as at the start or end of a fluid operation, resulting in excellent workability. , it has remarkable effects such as maintaining a constant sorting performance and improving the efficiency of sorting work.
