The reflected light of both sides.

In addition, the downstream side illumination unit accommodates a long-length light projection body in a downstream side illumination unit housing case which is formed in a state in which a light transmission window facing the measurement target portion is extended and extends in a granular body group expansion direction. Since the inside of the storage unit of the downstream side illumination unit is separated from the measurement target portion by the transmission window, the light projected from the light projection body can be projected toward the measurement target portion while preventing the measurement target portion from being irradiated. The dust and the like are scattered and adhere to the light projecting body.

Then, the downstream side light receiving portion is formed to be wider and narrower than the downstream side illumination portion in the direction in which the granular body group is expanded, and is housed in the downstream side light receiving casing that is connected and supported by the downstream side illumination unit housing case.

The electric wiring h to which the device 9 is connected is provided in a state of being inserted into the inside of the tubular portion 28.

Further, electrical wiring (not shown) connected to the linear light sources 41A and 41B and the respective light receiving devices 5A, 5B, and 5C is configured to be connected to the control device 9 by being disposed inside the storage body 54. As described above, the electric wiring h is not exposed in the measurement passage area through which the rice grains pass. In the part where the rice grain passes, for example, a small animal such as a mouse enters, but the electric wiring h is not exposed to the measurement passage area, and it is possible to avoid the disadvantage that the electric wiring is damaged by a small animal.

Next, the control configuration will be described.

As shown in Fig. 14, a control device 9 for use by the microcomputer is provided, and image signals from the respective light receiving devices 5A, 5B, and 5C and operation information from the operation panel 11 are input to the control device 9. As shown in Fig. 2, the operation panel 11 is provided in the front cover member 10 in a state of facing the outside, and various settings can be made. On the other hand, the control device 9 outputs a drive signal for turning on the linear light sources 30A and 30B, and a solenoid valve 45 for intermittently driving the air supplied to the respective discharge nozzles 6a by the air manifold 42. The driving signal of the solenoid valve driving circuit 29; the driving signal of the vibration generator 26 for the vibrating feeder 3B; and the signal for controlling the command of the dimming device 35.

Then, the light receiving information by the light receiving means 5 is executed by the control device 9, and it is determined whether or not the granular material (including foreign matter such as defective rice grains, small stones, or glass sheets) to be separated (hereinafter referred to as an object to be separated) is determined. The evaluation processing means 100 for the granular body discrimination processing; and the supply amount control means 101 for controlling the operation of the vibration feeder 3B in order to change the transfer flow rate of the rice grain group k based on the detection information of the pressure sensor 48.

The control device 9 is configured to issue, to the solenoid valve drive circuit 29, an instruction to actuate the control valve 45 corresponding to the switching state in the air discharge portion 6a among the plurality of control valves 45, based on the determination result. News.

Next, the evaluation processing means 100 will be described.

The evaluation processing means 100 is for each of the front side reflected light receiving means 5A and the rear side reflected light receiving means 5B, and the light amount value obtained by receiving light in each unit light receiving portion 5a for each unit light receiving portion 5a is not pressed. The determination of the appropriate light amount range ΔEh set in advance by each unit light receiving unit 5a, and whether or not the light amount value obtained by receiving light in each unit light receiving unit 5a of the transmitted light receiving device 5C is not pressed for each unit light receiving unit 5a The determination of the appropriate light amount range ΔEt set by the light receiving unit 5a is determined as the object to be separated when the light receiving amount of any unit light receiving unit 5a is not in the appropriate light amount range ΔEh or ΔEt.

Further, the evaluation processing means 100 is configured to obtain, for each unit light receiving unit 5a of each of the light receiving devices 5A, 5B, and 5C, the set amount of light receiving amount data obtained by sampling, and to obtain the dark side from the dark side. The sides are divided into a power distribution (also referred to as a histogram) of the respective light amount values in the complex phase, and the appropriate light amount ranges ΔEh and ΔEt are set based on the degree distribution.

Specifically, in the state in which the amount of illumination light of the linear light sources 30A and 30B is extremely stable, the amount of received light is set for each unit light receiving unit 5a of each of the light receiving devices 5A, 5B, and 5C while flowing the rice grain group k. Sampling. However, in this case, the air blowing device 6 is not operated. Next, as shown in FIG. 18, the evaluation processing means 100 is configured such that in the degree distribution hg, the dark side and the bright side correspond to consecutive fields in which the degree values of the respective light amount values continuously exist (indicated by oblique lines in the drawing). The upper side light amount value TH1 is set by the near-end position of the upper end portion, and the upper limit value T1 of the appropriate light amount range is set by the upper side light amount value TH1 on the bright side at a position away from the set light amount K1, and corresponds to the lower end of the continuous field. The lower side light amount value TH2 is set in the near position of the portion, and the lower limit value T2 of the appropriate light amount range is set at a position away from the set light amount K2 on the dark side by the lower side light amount value TH2. Each of the set light amounts K1 and K2 is set in advance as Control constant.

However, although not described in detail, the upper light amount value TH1 or the lower side light amount value TH2 is corrected based on the set number of received light amount data obtained every predetermined time with the sorting operation.

The appropriate light amount range ΔEt when the detected light is transmitted light will be described below.

In the case of the transmitted light, as shown by the output waveform of the transmitted light receiving device 5C of Fig. 16, the output voltage corresponding to the amount of received light of each unit light receiving unit 5a is within the appropriate light amount range ΔEt for the rice grain group k, Normal rice grains (granular bodies not to be separated) are present, and if the appropriate range ΔEt is not set, it is determined that there are defective rice grains or foreign matter (objects to be separated). Here, the appropriate light amount range ΔEt for transmitted light is set in a range of a predetermined upper and lower width from the output voltage level e0 of the normal transmitted light to the normal transmitted light.

Next, when it is smaller than the appropriate light amount range ΔEt, it is determined that there is a defective rice grain or foreign matter having a transmittance lower than that of the normal rice grain (for example, black stone particles), and if it is larger than the appropriate light amount range ΔEt, it is determined that the transmittance is larger than the normal rice grain k. Bad rice k or foreign matter on the bright side. In the case of the defective rice grain k or the foreign matter on the bright side, the transparent glass piece with a light color is a foreign matter having a transmittance higher than that of the normal rice grain k, and the "glutinous rice" when the normal rice grain k is set to "glutinous rice" becomes The transmittance is greater than the poor rice k of the normal rice k.

In the sixteenth diagram, the output voltage (light-receiving amount) of the unit light-receiving portion 5a is defined as a position at which a part of the colored portion of the rice grain k is present, a position such as black stone (indicated by e1), and a position where the body is broken (indicated by e2). Medium, located below the appropriate light amount range ΔEt, in addition, When there is a foreign matter having a transmittance higher than that of the normal rice grain, as shown by the position e4, it is in a state above the appropriate light amount range ΔEt.

Next, an appropriate light amount range ΔEh when the detection light is reflected light will be described.

In the case of reflected light, as shown by the output waveform of the front side reflected light receiving device 5A (or the rear side reflected light receiving device 5B) of Fig. 17, the output voltage corresponding to the amount of light received by each unit light receiving unit 5a is located. When the appropriate light amount range ΔEh is within, it is determined that there is normal rice grain, and if it is not in the appropriate light amount range ΔEh, it is determined that there is a defect or foreign matter of the rice grain. Here, the appropriate light amount range ΔEh for the reflected light is set to a range of a predetermined upper and lower width with respect to the output voltage level e0' of the standard reflected light of the normal rice grain.

In Fig. 17, the position where the rice grain k has a part of the colored portion (indicated by e1') or the position where the body is broken (indicated by e2') is exemplified in a state in which the appropriate light amount range ΔEh falls on the lower side. When there is a foreign matter such as a glass piece, the strong direct reflected light from the foreign matter, as indicated by the position e3', falls to the upper side from the appropriate light amount range ΔEh. Further, although not shown, the black stone or the like has a very small reflectance, and therefore, in the waveform, the appropriate light amount range ΔEh falls to the lower side.

As described above, the appropriate light amount range ΔEt and ΔEh (corresponding to either of the transmitted light and the reflected light) set and corrected for each unit light receiving unit 5a of each of the light receiving devices 5A, 5B, and 5C is as described above. The values of the limit value T1 and the lower limit value T2 are stored in the memory device LUT (for front reflected light, back reflected light, and the like) which are stored in the control device 24 as a check table for the defect detection processing. LUT for transmitted light).

Then, the processing system for determining whether or not the object is an object to be separated is transferred as follows, while the rice grain group k to be discriminated is transferred by the transfer means 3.

In other words, as shown in Fig. 19, the light amount value j and the position data i of the unit light receiving unit 5a of each of the light receiving devices 5A, 5B, and 5C are transferred while the rice grain group k is transferred (i = 0 to [unit light receiving unit] The number -1]) produces a correspondence to input (step 1). Next, determination processing of the light amount value j of the unit light receiving unit 5a of each of the light receiving devices 5A, 5B, and 5C is performed (step 2). Specifically, according to the light amount value j of each of the front side reflected light receiving device 5A and the rear side reflected light receiving device 5B, the position data i (i = 0 to [the number of unit light receiving portions - 1]) is used for each. When the light amount value j is within the appropriate light amount range ΔEh, the unit light receiving unit 5a determines that it is normal rice grain, and if the light amount value j is not in the appropriate light amount range ΔEh, it is determined as the object to be separated. In the same manner, each of the unit light receiving units 5a indicated by the position data i (i = 0 to [the number of unit light receiving units - 1)) is determined whether or not the light amount value j is in the same manner. The appropriate amount of light is within the range ΔEt.

When the light amount value j of any unit light receiving unit 5a of the front side reflected light receiving device 5A and the rear side reflected light receiving device 5B is determined as the object to be separated in the appropriate light amount range ΔEh, the reflected light measurement portion J1 is used. After the first delay time t1 required for the separated portion passes, the air is ejected by the appropriate discharge nozzle 6a of the air blowing device 6 (steps 3, 4, and 7).

In addition, when the light amount value j of the unit light receiving unit 5a of any one of the transmitted light receiving devices 5C is not in the appropriate light amount range ΔEt, it is determined as the object to be separated. At the time of the second delay time t2 required for the transmitted light measurement portion J2 to the separation portion, the drive of the solenoid valve drive circuit 29 is outputted so that the air is ejected by the appropriate discharge nozzle 6a of the air blowing device 6. Signal (steps 5, 6, 7). The solenoid valve drive circuit 29 operates the solenoid valve 45 corresponding to the appropriate discharge nozzle 6a to eject the air from the discharge nozzle 6a.

As described above, the object to be separated is blown by the respective discharge nozzles 6a of the zones corresponding to the position, and separated from the normal rice grains, and collected in the mouthpiece 50 for collecting the separated matter. On the other hand, the normal rice grain which is not determined as the object to be separated is recovered to the mouth portion 49 for normal particle recovery.

The object to be separated which is collected in the mouthpiece portion 50 for the separation of the separated material is discharged to the outside by the outlet outlet 52, and the normal rice grain group k recovered in the mouth portion 49 for normal particle recovery is guided. The guide plate 53 is guided downward and is supplied to the lower conveyance start end portion of the discharge lift conveyor device 8, and is lifted and transported by the discharge lift conveyor device 8, and discharged to the outside of the device by the discharge port 7. .

Next, the supply amount control means 101 will be described.

The supply amount control means 101 is configured such that when the air pressure detected by the pressure sensor 48 is higher than a predetermined lower limit value, when the detection pressure is lower, the detection pressure is lower than when the detection pressure is higher. The mode of transferring the flow rate by the transfer means 3 controls the operation of the transfer means 3 based on the detected pressure, and changes the transfer flow rate. When the detected pressure is lower than the lower limit value, the operation of the transfer means 3 is controlled to be transferred. The transfer of the rice grain group k by means of the means is stopped.

In other words, the supply amount control means 101 is configured to adjust the transfer flow rate of the rice grain group k to the first set value when the detected pressure Px of the pressure sensor 48 is higher than a predetermined switching determination value Ps2. When the detected pressure Px is equal to or less than the switching determination value Ps2, the transfer flow rate of the granular body group is adjusted to a second set value which is smaller than the first set value by the set value, and the transfer means 3 is controlled based on the detected pressure Px. The action is to change the transfer traffic.

In addition, the particulate matter group which is the object to be selected is actually subjected to the transfer means, and the evaluation processing means 100 performs the granular body discrimination process, and the test processing means 100 is judged as The granular body of the granular material to be separated is separated by the air ejection device 6, and the transfer flow rate value at which the separation process can be performed in an appropriate state is obtained, and the transfer flow rate value is set to the first set value.

Specifically, when the test surface is transferred while the rice granule group k is being operated, the transfer flow rate of the vibrating feeder 3B is manually changed by operating the operation panel 11, and the transfer which can be separated in an appropriate state is obtained. Flow value.

When the sorting process for the rice kernel group k as the sorting target is started, the supply amount control means 101 executes the flow rate adjusting process of the transfer means 3 based on the pressure detection. The following is a detailed description based on the flowchart of FIG.

When the flow rate adjustment process is started, the detected pressure Px detected by the pressure sensor 48 is input (step 10), and it is determined whether or not the detected pressure Px is equal to or lower than the preset lower limit value Ps1 (step 11). If the pressure is detected Px When it is not higher than the lower limit value Ps1 and not higher than the lower limit value Ps1, it is determined whether or not the detected pressure Px is equal to or lower than the switching determination value Ps2 set in advance as the pressure higher than the lower limit value Ps1 (step 12). . Then, when it is determined that the detection pressure Px is not higher than the switching determination value Ps2 and higher than the switching determination value Ps2, the flow rate is maintained as the original flow rate, that is, the initial setting. When the detected pressure Px is equal to or less than the switching determination value Ps2, the user is notified of insufficient air pressure by a notification means (for example, a voice type notification means or a message display type notification means) (not shown). The operation of the transfer means 3 adjusts the transfer flow rate of the rice grain group to a second set value that is smaller than the first set value by a set amount (steps 13 and 14). Specifically, the transfer rate of the rice kernel group is adjusted to the second set value by changing the transport speed of the vibrating feeder 3B. Next, after the transfer flow rate is adjusted to the second set value, the transfer flow rate is maintained at the second set value.

When it is determined in step 11 that the detected pressure Px has decreased to the lower limit value Ps1 or less, since it is not easy to blow off the object to be separated by air, the separation is performed. The means (for example, a voice notification means or a message display type notification means) notifies the abnormal state, and stops the operation of the vibrating feeder 3B (steps 15, 16).

When it is determined in the above-described step 12 that the detected pressure Px is higher than the switching determination value Ps2, the flow rate is maintained as the original flow rate, that is, the initial set first set value is processed. The process of adjusting the transfer flow rate of the rice grain group k to the first set value corresponds to the process.
