Abstract

PURPOSE: To correct the adjustment position of brown rice discriminating plate based on a standard with a boundary detected position by a paddy-brown rice discriminating sensor while considering the taste of an operator and easily carry out the adjustment correspondingly to the taste in relation to the operation in the case when a manual adjustment operation by the operator is carried out during automatic adjustment of the brown rice discriminating plate. CONSTITUTION: When a swinging sorting plate 1 starts sorting, brown rice in mixed rice and paddies are deflected and distributed to a swinging upper side 1c and a swinging lower side 1d, respectively, while the mixed rice is moving from a supply side 1a to a discharge side 1b and unsorted mixed rice is sorted in the middle part while being deflectedly distributed. A paddy-brown rice discriminating sensor 2 is therefore moved reciprocally to detect the boundary position of the brown rice distributed area and mixed rich distributed area and, based on the detected result, the brown rice discriminating plate 5 is moved and adjusted. In the case when an operator manually adjusts a discriminating plate adjusting motor 8 during such an automatic operation at the discriminating position, the shift distance of the brown rice discriminating plate movement adjusting means is corrected and the automatic adjustment of the discriminating plate is carried out based on the corrected shift distance as a standard.

出制御に移行する。Next, the control contents of the control unit 11 will be described. First, when the main motor (not shown) is driven, the rotating parts of the hulling / sorting machine are driven, and the full sensor 9 detects whether or not the hull hopper is being pulled into the hull hopper. Then, the paddy supply control valve is adjusted to open, the rocking clutch is engaged and the paddy sorting operation is started. Then, the light amount of the paddy / brown rice discrimination sensor 2 is adjusted, and the paddy and brown rice are adjusted to have a predetermined detection voltage. That is, when the swing sorting plate 1 enters a stable sorting state (grains are distributed over the entire width from the rocking side 1c to the rocking side 1d), the light amount adjustment control is started, and the control unit 11 sets the initial reference light amount adjustment voltage. Then, the paddy / brown rice discrimination sensor 2 starts to move from the most swaying upper side 1c to the most swaying lower side 1d, the grain voltage is read, and as shown in FIG. To the side, the detection voltage of brown rice, mixed rice, and paddy is detected and detected (there is a lot of water on the surface of brown rice,
The voltage difference is detected because the water content on the paddy surface is low. ), A comparison is made as to whether the brown rice voltage value on the swaying side and the paddy voltage value on the swaying side are within the predetermined reference voltage values. When the light amount is adjusted to the decreasing side or the increasing side and falls within the range of the reference voltage value, the light amount adjustment ends. Then, the voltage value at the boundary between the brown rice voltage value and the mixed rice voltage value in the voltage distribution chart of FIG. 4 is set as the boundary reference voltage value (horizontal dotted line in FIG. 4 (2)). When the light amount adjustment control is completed, the process shifts to the control of detecting the boundary position between the brown rice and the mixed rice on the brown rice partition plate 5 by the paddy / brown rice discrimination sensor 2.

率を上げながら、作業を継続することがある。Then, a movement command is issued to the uppermost sway of the paddy / brown rice discrimination sensor 2 to move, and the sensor swayest upper movement sensor 14 detects the movement of the paddy / brown rice discrimination sensor 2 to the uppermost sway and moves. Is completed. Then, a command to move the paddy / brown rice discrimination sensor 2 to the swaying side is issued and moved, and the detection voltage value V of the paddy / brown rice discrimination sensor 2 is sequentially read. Then, as shown in the flow chart of FIG. 4, when the detected voltage value V is compared with the boundary reference voltage value and the detected voltage value V is smaller than the boundary reference voltage value, the sensor adjustment motor 4 is further moved downward by one step. When the detected voltage value V is greater than the boundary reference voltage value, the sensor adjustment motor 4 is instructed to move upward by one step, and the paddy / brown rice is discriminated. The sensor 2 is moved up and down one step, and, in this way, is moved and adjusted to the boundary position between the brown rice and the mixed rice. In this way, when the movement adjustment of the paddy / brown rice discrimination sensor 2 to the boundary position is completed, the movement distance from the uppermost sway of the paddy / brown rice discrimination sensor 2 to the boundary position is, for example, that of the sensor adjustment motor 4. It is calculated from the normal and reverse rotation speeds. Then, the control unit 11 instructs the partition plate adjusting motor 8 to subtract the reference shift distance of the predetermined distance from the calculated sensor moving distance to calculate the moving distance of the brown rice partition plate 5, and to command the movement of the brown rice partition plate 5. Is issued and movement is adjusted. Then, brown rice partition plate 5
The brown rice is separated at a position where paddy is not mixed, and the brown rice is taken out. The reference shift distance of a predetermined distance for determining the moving position of the brown rice partition plate 5 from the boundary detection position of the paddy / brown rice discrimination sensor 2 is stored in the EEPROM. By adding the following contents to the adjustment control of the brown rice partition plate 5 described above, the brown rice partition plate control suitable for the operator can be performed. That is, after the partition position of the brown rice partition plate 5 is automatically adjusted and set, the partition plate adjustment motor 8 is manually adjusted further according to the operator's preference to move it to the upper side or the lower side by a predetermined distance. The work may be continued while making adjustments to improve the sorting accuracy and the sorting efficiency.

て説明する。The lower half of FIG. 5 shows the control flow. In this case, the moving distance to the rocking side or the rocking side is detected by the forward / reverse rotation speed of the partition plate adjusting motor 8, and the reference shift distance of the predetermined distance stored in the EEPROM is: The boundary reference position of the paddy / brown rice discrimination sensor 2 is rewritten to a correction reference shift distance that takes into account the manual adjustment distance to the upside or downside of the operator. From this, the adjustment position of the brown rice partition plate 5 is determined. Thus, the brown rice partition plate can be controlled according to the operator's preference. Next, the work end control of the swing sorting device shown in FIG. 6 will be described.

When the paddy sensor 10 detects the absence of paddy, it is determined that the work is completed, the paddle supply control valve (not shown) is closed and the swing clutch on / off motor 17 is instructed to swing the clutch. The swing clutch is disengaged and the swing selection plate 1 stops swinging. Next, the partition plate adjustment motor 8 is instructed to move to the uppermost rocking position, the brown rice partition plate 5 moves to the uppermost shaking position, and the movement to the upper shaking position is detected by the brown rice partitioning plate uppermost moving sensor 12. When the movement is detected and the movement is completed, the rocking clutch is commanded to enter the rocking clutch, and all the grains discharged from the rocking sorting plate 1 are returned to the hulling portion (not shown) and hulled. When the detection value of the selection state of the paddy / brown rice discrimination sensor 2 becomes higher than the reference value, the brown rice partition plate 5 is moved from the uppermost position to the lower side for a predetermined distance to move the brown rice out of the partitioning machine. The normal work end process of taking out is executed.

混入するという問題点が発生していた。In the conventional device, at the end of the work, a rice cutting sensor is provided in the mixed rice hopper of the rocking and sorting device, and the brown rice partition plate is moved to the uppermost position in relation to the detection of the rice cutting by the rice cutting sensor. There is a device for moving to the end of the work of the swing sorting device. However, in the conventional device, the supply of grains to the swing selection plate is stopped quickly, and moreover, since the brown rice partition plate is moved while swinging the swing selection plate, the number of grains to be selected decreases. The movement of the grain distribution to the upper side does not match the movement of the brown rice partition plate to the upper side, and the brown rice partition plate partitions the brown rice mixed with paddy, and the paddy rice mixed with the paddy rice taken out of the machine is mixed. There were dots.

のである。However, in this embodiment, as described above, since the swinging of the swing selecting plate 1 is stopped and the brown rice partition plate 5 is moved to the upper side of the swing, the paddy rice is mixed with the grain. In addition, the partition plate adjusting motor 8 does not need to have a large capacity, and the drawbacks of the conventional device can be solved. In addition, as shown in the flow chart of FIG.
When the absence of paddy is detected, it is determined that the work is completed, and the brown rice partition plate 5 may be moved to the uppermost rocking side without stopping the rocking of the rocking sorting plate 1 while continuing the rocking. . In this embodiment, a hulling sensor 10 for determining the end of work is provided in a hulling section (not shown) which is a front stroke of the swing sorting device. Therefore, in the initial stage of the upward movement of the brown rice partition plate 5, the grains remaining in the slide-down rice wind selecting unit (not shown) and the conveying path (not shown) in the previous process are supplied to the swing selecting plate 1. The grain is continuously supplied, and the uneven movement of the grain to the upper side of the grain is delayed. During that time, the brown rice partition plate 5 can be moved to the uppermost side and the rice is mixed by the brown rice partition plate 5. There is little possibility of partitioning brown rice, and the drawbacks of conventional devices can be eliminated.
