In the present embodiment, it is seen that light region is configured with CIS232 in the front side of subject sorting unit 10, near-infrared Light region configures the rear side in subject sorting unit 10 with CIS234.In addition, the sensor and near-infrared of visible light region The sensor in light region is not limited to such configuration, as long as according to the type of cereal, type of the unfavorable condition of cereal etc. Suitably configure.

The visible light region sensor that CIS232 is for detecting the visible light for having penetrated cereal.It uses visible light region CIS232 is detectable issued from front side RGB light emitting diode 212 and rear side RGB light emitting diode 222 after penetrated cereal can It is light-exposed.

Cereal is first passed through by the visible light that front side RGB light emitting diode 212 issues, is then irradiated to background body 242, quilt Towards visible light region CIS232 after the reflection of background body 242.Visible light region CIS232 receiving is reflected by background body 242 Visible light.The light of cereal, the transmitance of available cereal have also been included through in the visible light reflected by background body 242.

In addition, being used after the visible light-transmissive cereal that rear side RGB light emitting diode 222 issues towards visible light region CIS232.Visible light region is received with CIS232 through the visible light for being directly toward visible light region CIS232 after cereal.

It follows that visible light region is configured to receive the visible of optical path VF and optical path VR the two optical paths with CIS232 Light, optical path VF are to use after being reflected from the light that front side RGB light emitting diode 212 issues by background body 242 towards visible light region The optical path of CIS232, optical path VR are to use from the light that rear side RGB light emitting diode 222 issues through after cereal towards visible light region The optical path of CIS232.

<<<the control processing of control processing system 300>>>

Hereinafter, subject sorting unit has been turned on, signal processing substrate 310, image procossing substrate 320 and air cannon control After the initial actuatings such as the initialization in substrate 330 are fully completed, steadily work.

Fig. 7 and Fig. 8 is the signal processing substrate judgement processing executed in signal processing substrate 310.

Initially, the CPU of signal processing substrate 310 determines 1 slide groove 146 (step S711) as check object.Such as Preceding described, in the present embodiment, slide groove 146 is totally 60 of the 1st slide groove 146 to the 60th slide groove 146, step The processing of S711 is to determine the processing of one serial number in slide groove 146.The processing of following step S713~S832 is needle Determine that cereal that 1 slide groove 146 of serial number is fallen judges whether it is the processing of non-defective unit to from by the processing of step S711.

Then, the CPU of signal processing substrate 310 judges whether the light reception intensity of visible light region CIS232 is pre- the 1st More than definite value (step S713).Here, so-called 1st predetermined value is the value of the transmitance about visible light, it is according to cereal The value that color determines, can be suitably determined according to the color for the cereal that should be removed as defective products.That is, the judgement of step S713 Processing be for cereal color judge cereal whether be defective products processing.For example, be the case where cereal becomes heavy colour state, Belong to the judgement for removing the cereal for having turned into heavy colour state as defective products.

The CPU of signal processing substrate 310 is being determined as visible light region CIS232 in the judgement processing of step S713 Light reception intensity more than the 1st predetermined value when (YES), determine timing start time (step S715), determine stand-by time (step S717), valve open hour (step S719) is determined.

So-called " timing start time " above-mentioned, " stand-by time " and " valve open hour " refer to carry out air cannon Parameter used by the open and close control of 410 valve 412 (referring to Fig.1 5).Figure 15 is to indicate " timing start time ", " when standby Between ", the timing diagram of the relationship of " valve open hour ".

The starting phase of timer at the time of " timing start time " is the open and close control for starting decision valve 412.It is logical Starting timer is crossed, timing is started, timer value is updated.According to timer value, judge whether to have already been through " when standby Between " and " valve open hour ".

" stand-by time " is standby time until executing valve Open control.That is, the judgement in step S713 is handled In, when being determined as the light reception intensity of visible light region CIS232 more than the 1st predetermined value, determine that cereal is defective products, this When not direct relief valve 412, but the Open control (the time point t3 of Figure 15) of valve 412 is executed after stand-by time.From It is determined as that cereal is that defective products starts until the front for the gas vent 414 that cereal further fell and reached air cannon 410 is Only, the time of a certain degree is needed.Until reaching the gas vent 414 of air cannon 410 from being determined as the cereal for defective products Front until time be exactly stand-by time.

It can become early when " stand-by time " is too short, at the time of valve 412 is opened, therefore be possible to compare sometimes and be judged as Cereal that the cereal of defective products is fallen earlier blows out the air stream from air cannon 410, exists being judged as of first falling is good A possibility that cereal of product removes.In addition, valve 412 latens at the time of being opened, to as bad when " stand-by time " is too long The cereal of product can be slack-off at the time of starting blow out air.Therefore, insufficient air can only be supplied to the cereal as defective products Amount is unable to fully change moving direction.Bucket 154 is stored as a result, not being able to guide to defective products, existing makes as defective products Cereal is mixed into a possibility that in the cereal as non-defective unit.Therefore, in order to accurately only remove the cereal for being judged as defective products, It is " stand-by time " appropriate that it is necessary to determinations.

It in the case where light weight, falls and slows, the time until the front of arrival gas vent 414 can be elongated.Cause This, in the case where light weight, it is necessary to be set to " stand-by time " longer.In addition, falling speed in the case where quality weight Degree becomes faster, and the time until reaching the front of gas vent 414 shortens.Therefore, in the case where the quality of cereal weight, it is necessary to will " stand-by time " is set to shorter.

" valve open hour " are the time (the time point t4 of Figure 15) from relief valve 412 until closing, and are from valve The time of air is discharged in 412 gas vents 414 being opened.The amount that the air of discharge is determined according to " valve open hour ", to judgement For the cereal blow out air stream of defective products, so that it is determined that the power (momentum) applied to cereal.

In the case where " valve open hour " are short, the pent moment of valve 412 can become early, therefore to being determined as defective products It can shift to an earlier date at the time of cereal blow out air.Therefore, insufficient air capacity, Wu Fachong can only be supplied to the cereal as defective products Ground is divided to change moving direction.Bucket 154 is stored as a result, not being able to guide to defective products, generates and is mixed in the cereal as non-defective unit A possibility that having entered the cereal as defective products.In addition, in the case where " valve open hour " are long being possible to that quilt can be compared sometimes The cereal for being determined as that the cereal also evening of defective products falls also blows out the air stream from air cannon 410, in this case, can also produce Raw a possibility that removing the cereal for being judged as non-defective unit.Therefore, the paddy of defective products is judged as in order to accurately only remove Object, it is necessary to determine " valve open hour " appropriate.

As previously mentioned, falling speed in the case where light weight and latening, the time by the front of gas vent 414 is elongated. Therefore, in the case where the light weight of cereal, it is necessary to will be set to " valve open hour " longer.In addition, in the feelings of quality weight It under condition, falls speed and becomes faster, shortened by the time in the front of gas vent 414.Therefore, in the case where grain quality weight, have Necessity will be set to " valve open hour " shorter.

<<<concrete example of the moving direction change of cereal>>>

Figure 12~Figure 14 is the schematic diagram for indicating the concrete example of moving direction of change cereal.

As shown in figure 12, it is fallen obliquely downward from the cereal GR that slideway 140 is detached from.When cereal GR is present in irradiation area When IR (black circle), the visible light issued from front side RGB light emitting diode 212, the depth issued from front side UV LED 214 Ultraviolet light, the near infrared light issued from front side infrared light-emitting diode 216 are issued from rear side RGB light emitting diode 222 Light, the deep ultraviolet light issued from rear side UV LED 224 and the near-infrared issued from rear side infrared light-emitting diode 226 Illumination is mapped on cereal GR.

As previously mentioned, according to being issued from front side RGB light emitting diode 212 and rear side RGB light emitting diode 222 and penetrating paddy The visible light of object GR detects the transmitance of cereal GR.In addition, shining according to from front side RGB light emitting diode 212 and rear side RGB The visible light that diode is issued and reflected by cereal GR detects the reflectivity of cereal GR.Also, according to from front side infraluminescence two Pole pipe 216 and rear side infrared light-emitting diode 226 issue and have penetrated the near infrared light of cereal, detect the moisture of cereal GR.Separately Outside, according to the deep ultraviolet light issued from front side UV LED 214 and rear side UV LED 224, in cereal GR In produce the bacterium such as mould in the case where, detect the fluorescence that issues from mould.Determine that cereal GR is good according to these testing results Product or defective products.

When cereal GR is determined to be defective products, at the time of cereal GR passes through the front of gas vent 414, from gas vent 414 discharge air, change the moving direction of cereal GR.Cereal GR is guided towards defective products storage bucket 154 as a result,.Another party Face, when cereal GR is determined to be non-defective unit, air is not discharged in gas vent 414, and cereal GR is used towards non-defective unit and stored bucket 152.

As shown in figure 13, on the downside of the cereal GR fallen there are in the case where bad part FP, the bad portion of cereal GR FP is divided early to reach irradiation area IR than the central portion CT of cereal GR reaches irradiation area IR (black circle) also.In addition, bad portion Dividing FP is according to the part for being judged as defective products with transmitance, reflectivity, moisture, Fluorescent light etc..

As described above, there are when bad part FP at the position of central portion CT more on the lower than cereal GR, In It penetrates in the IR of region, bad part FP can be detected at the moment earlier.In addition, cereal GR is because pass through exhaust at the moment earlier The front in hole 414, therefore start also to become at the time of air is discharged relatively early, it is able to extend the time to cereal GR blow out air, Thus sufficient air capacity can be supplied to cereal GR.Therefore, the moving direction of cereal GR can be changed, it can accurately direction Defective products guides cereal GR with storage bucket 154.

In addition, in the case where the entirety of cereal GR produces bad part FP, because the lower end of cereal GR is bad Part FP has initially been detected, therefore similarly can similarly be supplied to cereal GR in early detection bad part FP Sufficient air capacity, therefore the moving direction of cereal GR can be changed, bucket 154 can be stored towards defective products guide cereal GR。

As shown in figure 14, on the upside of the cereal GR fallen there are in the case where bad part FP, the bad portion of cereal GR FP is divided just to reach irradiation area IR after the central portion CT of cereal GR reaches irradiation area IR.

In this way, being shone at the upper position the central portion CT than cereal GR there are in the case where bad part FP It penetrates in the IR of region, bad part FP is detected at the time of later.Therefore, because cereal GR can pass through gas vent at the time of later 414 front is substantially shortened to the time of cereal GR blow out air so starting also become late at the time of air is discharged, No normal direction cereal GR supplies sufficient air capacity.Therefore, as one can imagine the moving direction of cereal GR can not be changed, it is difficult to by cereal GR is accurately guided to defective products and is stored bucket 154.

<<<" timing start time ", " stand-by time ", " valve open hour ">>>

Figure 15 be " riser portions " and " falling portion " of the pulse for indicating NG signal, " timing start time ", " stand-by time ", The timing diagram of the relationship of " valve open hour ".

As previously mentioned, " timing start time " is timer at the time of starting the open and close control for determining valve 412 The starting phase.In the present embodiment, as shown in figure 15, NG signal is the signal being made of 1 pulse, starts the starting of timer Phase can be set as in the riser portions (the time point t1 of Figure 15) of pulse or the falling portion (the time point t2 of Figure 15) of pulse Any one.Using the riser portions of pulse as when the starting phase that timer starts, at the time of the Open control of valve 412 can be shifted to an earlier date (the time point t3 of Figure 15).On the other hand, using the falling portion of pulse as when the starting phase that timer starts, valve can be delayed At the time of 412 Open control (the time point t3 of Figure 15).Can by " stand-by time " keep certain time (do not change " to The machine time ") in the case where, the starting phase of change timer starting.In particular, falling in the case where the heavier mass of foreign matter etc. Fast speed, therefore the starting phase that the riser portions of pulse are started as timer are fallen, the Open control of valve 412 can be shifted to an earlier date At the time of foreign matter reaches the front of gas vent 414 air can be discharged to foreign matter in moment.

" stand-by time " is standby time until executing the Open control of valve 412.Cereal is judged as defective products When, and indirect relief valve 412, but the Open control (the time point t3 of Figure 15) of valve 412 is executed after stand-by time.From Cereal is judged as starting when defective products until cereal further falls and reach the front of the gas vent 414 of air cannon 410 Until, need the time of a certain degree.Until reaching the exhaust of air cannon 410 since when the cereal is judged as defective products Until the front in hole 414, it is necessary to standby.This period is stand-by time.

" stand-by time " can become early in short-term, at the time of valve 412 is opened, therefore sometimes from the air stream of air cannon 410 It is possible that can blow on the cereal fallen earlier than the cereal for being judged as defective products, falling in advance for non-defective unit will be judged as by generating A possibility that cereal fallen removes.In addition, when " stand-by time " is long insufficient air can be supplied to the cereal as defective products Amount, changes moving direction with being unable to fully.Bucket 154 is stored as a result, can not guide to defective products, is generated as defective products Cereal is mixed into a possibility that in the cereal as non-defective unit.

" valve open hour " are the time (the time point t4 of Figure 15) since relief valve 412 until closing, and are The time of air is discharged in the gas vent 414 being opened from valve 412.According to " valve open hour ", the air capacity of discharge is determined.

" valve open hour " in short-term, can supply insufficient air to the cereal as defective products, cannot sufficiently change movement Direction.Bucket 154 is stored as a result, can not guide to defective products, generates and is mixed into the paddy as non-defective unit as the cereal of defective products A possibility that in object.In addition, the air stream from air cannon 410 may be blown to than being judged as when " valve open hour " are long The cereal that defective products cereal is fallen later can also generate a possibility that removing the cereal for being judged as non-defective unit at this time.

As previously mentioned, when the light weight of cereal, it is necessary to be set to " stand-by time " longer.In addition, the quality of cereal When weight, it is necessary to be set to " stand-by time " shorter.For example, quality can become in the case where cereal desiccation due to bad Gently, it is therefore necessary to be set to " stand-by time " longer.Cereal because bad moisture content it is more in the case where, quality can become weight, And when being the foreign matters such as plastics, because of heavier mass, it is necessary to be set to " stand-by time " shorter.

In addition, according to the type of cereal, and standard quality relevant information (average value or the deviation of the cereal as non-defective unit Deng) it has been determined that also being had determined that with the relevant information of speed (average value or deviation etc.) that falls of standard of the cereal as non-defective unit. Falling speed and can determine " timing start time ", " stand-by time " and " valve open hour " from the standard.I.e., it is possible to determine For the cereal of non-defective unit to be determined as to " the timing start time ", " stand-by time " and " valve open hour " of non-defective unit.In addition, according to According to the type for the unfavorable condition that the type of cereal may occur, can also determine and the deviation of the quality of standard, variation.That is, It can determine " timing start time " for the cereal of defective products to be determined as to defective products, " stand-by time " and " when valve is open Between ".

It, can also be according to can other than the type of cereal in this way, in the subject sorting unit 10 of present embodiment The type of the unfavorable condition of generation determines " timing start time ", " stand-by time " and " valve open hour ".It determines in this way " timing start time ", " stand-by time " and " valve open hour " be stored in signal processing substrate 310 ROM and/or RAM, In the ROM and/or RAM of image procossing substrate 320, according to the type of unfavorable condition, reads and exported to sky from ROM and/or RAM Air gun control base board 330.

Specifically, step S821, S831, Fig. 9 of step S721, S731, Fig. 8 of described Fig. 7 step S921, In the processing of step S1021, S1031 of S931, Figure 10, according to the type of unfavorable condition, from the ROM of signal processing substrate 310 And/or RAM, the ROM of image procossing substrate 320 and/or RAM read " timing start time ", " stand-by time " and " when valve opening Between ", and export to air cannon control base board 330.Air cannon control base board 330 is according to " meter corresponding with the type of unfavorable condition When start time ", " stand-by time " and " valve open hour ", from gas vent 414 be discharged air, so as to accurately only will determine It is removed for the cereal of defective products.

Also, as illustrated in Figure 14, at the time of according to bad part FP is able to detect, it is also contemplated that without normal direction cereal The case where air capacity of GR supply abundance.Therefore, the cereal of defective products is judged as in order to accurately only remove, it is necessary to set " valve open hour " appropriate.It can cereal size relevant information (average value, deviation determining according to the type of cereal and standard Deng), speed can be fallen according to the standard of non-defective unit cereal and size determines " timing start time ", " stand-by time " and " valve is open Time ".
