Description

DETAILED DESCRIPTION OF THE INVENTION The present invention generally relates to an oscillating sorting machine, and more particularly, the present invention relates to an oscillating sorting machine, and more particularly, the present invention relates to an oscillating sorting machine that separates brown rice and mixed rice on a sorting plate.
The brown rice partition plate is automatically moved to the boundary position to obtain finished rice with less paddy ([-1 rice fJl).

This (heavy equipment) (according to the optical sensor that detects the culm position of brown rice and mixed rice on the sorting table and the corresponding output) cuts the detected separation. The means for moving the unpolished rice to the position of the circle W is arranged so that the cutting plate moves and covers the position of the separated J3λ field on the sorting plate. Although the discharge control device contributes to the automation of the oscillating sorter, when the moving distance N1 of the brown rice partition plate toward the brown rice side is long, it causes a large amount of W in the paddy to be mixed into the finished rice. In other words, from the viewpoint of more accurately detecting the division boundary position between brown rice and mixed rice, Sen1no is selected as much as possible (1).
1 It is desirable to grow rice near the output side, and brown rice 1
Since there is a limit to the movement speed of one cut plate, if the moving distance of one cut plate on the brown rice side l\ is a person, before 119 plates reach the desired separation boundary position. The detected grains will be ejected from another plate/JI I, and therefore the ejection of rice will be increased according to the detected amount of PiIl boundary.
A large amount of paddy will be mixed into the grains that are taken out as finished rice.

The present invention was developed based on this viewpoint, and its purpose is to remove finished rice according to the detected separation boundary in the case where the moving distance of the serving plate toward the brown rice side is a person. The purpose of the present invention is to provide a device for controlling the discharge of rice from 14 types of oscillating sorting rocks.

The sorting plate 2 has a portion 11 of brown rice and mixed rice on the sorting plate near the discharge surface 2a. It has detection means 7 for detecting the ll boundary.

The separation boundary detection means 7 is connected to the upper blade of the sorting plate 2 (the eastern part 78 which is bridged parallel to the discharge surface 2a of the part 2 and the core part trA7a along the discharge surface 2a of the sorting plate 2). The optical sensors (So, S+, '++, Ss) that are The optical sensor So, which is a terrible one, always detects 1ε as a reference sensor.
+..., So) are arranged at predetermined intervals C to detect the separation boundary between brown rice and mixed rice. Each sensor distinguishes between unpolished rice and paddy by using the difference in q4 light φ between them, which is detected by a symmetrical optical lens. Each detection sensor (Sl,...,S
Regarding o), as will be described later, the output when the grain distribution state is detected in which the proportion of paddy mixed with brown rice is approximately 50% or more is considered to be a significant output. The separation boundary between brown rice and paddy at the time of 50% detection is now A5 brown rice, and for pn()Sl, it is at position a,
l? sensor S2, and position C for sensor S3.

The sensor S4 is at the position d, the sensor S5 is at the position e, and the sensor S6 is at the position [.

Each separation boundary position corresponding to a paddy contamination rate of 50% can be easily determined from the characteristics of grain distribution in shaking sorting.

The partition plates 4 and 5 are held on a shaft 8 substantially parallel to the discharge surface 2a of the sorting plate 2. The partition plate 4 is a paddy partition plate-C1 located near the separation boundary between paddy and mixed rice.This partition plate is fixed. The other partition plate 5 separates and discharges brown rice and mixed rice in accordance with the same boundary.The discharge surface 2 of the sorting plate 2 is driven by rotation of the brown rice partition plate moving shaft 9 provided on the shaft 8.

Communicate with. The valve indicated by reference numeral 1'1 in the sorting grain removal section 6 is as follows:
There is a flow path switching IYC that determines whether the finished rice flowing into the finished rice discharge port of the sorting plate 2 is to be flowed to the finished rice outlet [6C] or the mixed rice outlet 61). That is, when the valve 11 is in the state shown in the figure (JJI jJj), the finishing rice brushing upper rice outlet 6. c and is discharged outside C11ft, and in the reverse state (circulation) indicated by the two-dot chain line, the finished rice is fed to the mixed rice outlet 6b and is used as circulating rice in the machine.

It is possible to have a 1,7J exchange valve at the other end '11
The valve drive shaft 13 is fixed to the rotation shaft 11a of the valve drive shaft 11a, and 15 is an elastic body that acts to pull out the valve drive shaft 13 from inside the solenoid. When the solenoid 12 is not driven, the shaft 13 or the elastic body 15c' is pulled as shown by the solid line, so the switching valve 1'1 is in the JJI pre-dispatch state, and the solenoid 12

- If it is 2 (1-1-), it is possible to prevent a large amount of paddy from entering into the rice.On the other hand, if it is 1-2, then there will be paddy that should not be mixed into the finished rice. Based on this viewpoint, the differential output voltage of the differential amplifier 30 when T+≧T2 becomes 1 without being added is set as the reference value VA.

Therefore, the solenoid 12 outputs the difference output of the differential amplifier 30≧V
When the brown rice partition plate approaches the target separation boundary position, the drive is released and the switching valve 11 is brought into the discharge state.

With the above configuration, the brown rice partition plate 5 detects the most grains from the paddy as shown in FIG. 1 (Δ) and separates the grain S1? If the boundary position output means 20 provides an output voltage corresponding to the repair sensor S6 from the most unpolished rice when it is at the rod position a,
The output voltage of the output means 20 at the boundary position is the output type II of the potentiometer 10 which outputs the position 11 of the brown rice partitions 1 to 5, and the output horn of the differential amplifier 30 receives the output voltage 11 of the differential amplifier 30.
is solenoid PJ8! r! 11 from the reference voltage of means 40. This connection causes the solenoid RI8 actuating means 40 to operate, and the switching valve 11 enters the circulating state by driving the solenoid 12. When the brown rice partition plate 5 approaches the separation boundary position @r of the rice scoop, the difference output between the output voltage of the boundary position output means 20 and the output type J, □F of the potentiometer 10 becomes the reference voltage +,
If T: V becomes 2 smaller than A, the solenoid drive means 40 releases the drive of the solenoid 12, so 1i7
J exchange valve-11 returns to the discharge state.

When the difference between the output voltage of the boundary position output means 20 and the output voltage of the potentiometer E1 meter 10 is smaller than the reference voltage VA, for example, the brown rice partition plate 5 detects the separation boundary position a of the detection sensor S1.
, the voltage corresponding to the shadow field IQ @b of the adjacent detection sensor S2 is 151 Vl! The position output solenoid drive means 40 does not operate, only the cutting plate moving motor drive means operates, and the switching valve 11 does not enter the circulating state.

As explained above, according to the present invention, the movement of the brown rice partition plate
