【産業上の利用分野】
この発明は、荷受穀物処理施設に関する。
【0002】
【従来技術及び発明が解決しようとする課題】
従来、例えば籾を荷受する穀物乾燥調製施設あるいは玄米センターなどにおいては、荷受穀物毎に例えば荷受計量機の計量タンクからサンプリングする形態とし、このサンプリング量及びそのタイミングは任意に設定されるものである。また、サンプリングされたサンプル穀物の処理に要する所要時間は、機材の処理能力や時間当たりサンプル回数などに影響されるが、籾の場合、サンプル搬送時間、籾すり・粒選別時間、品位・食味測定時間、サンプル穀物排出時間のトータルは、短時間で処理される荷受計量に要する時間、即ち計量機への投入時間、計量時間、サンプル穀物の抜き取り時間、及び排出時間、に比較して一般に長い時間が必要とされる。
【0003】
従って、荷受されてくる穀物を順順に、計量し、サンプル評価するにはずれが生じて、全体で所要時間が拡大することとなり、異なる生産者毎に荷口が変わるが、その持込み重量のまちまちである。
また、荷口毎の重量が異なるがため、荷変わり直後にサンプリングすると却って前荷口のサンプル穀物が混在するなどの恐れがある。
【0004】
【課題を解決するための手段】
このためこの発明は、複数の荷受ホッパと、荷受穀粒の流量を調整する流量調整タンクと、異なる荷受ホッパ毎に荷受穀物を計量する荷受計量機と、荷受計量機から所定穀物量を設定量毎に複数回サンプリングするサンプラと、サンプラでサンプリングされた穀物を搬送するサンプル搬送装置と、サンプリングされた穀物の品質を検査する品質検査装置と、品質検査装置で検査された検査情報に基づいて穀物を収容する複数の原料タンクとを設けた荷受穀物処理施設において、
荷受穀物の荷受量の概算を設定する荷受量概算重量設定器を設け、荷受量概算設定重量器に入力された荷受概算重量が前記流量調整タンクの収容可能重量より大きいときには、荷受計量機で計量した穀物重量が予め設定した設定重量を超えるとサンプラでサンプリングを開始し、計量途中でサンプル搬送装置がサンプルの搬送を行ない、
荷受概算重量が前記流量調整タンクの収容可能重量以下のときには計量の開始と共にサンプラを所定タイミングで作動する構成とし、計量終了時にサンプル搬送装置がサンプルの搬送を行なうことを特徴とする荷受穀物処理施設の構成とする。
【0005】
【発明の作用及び効果】
上記の構成としたから、荷受概算重量が流量調整タンクの収容可能重量より大きい穀物が荷受された場合には、荷受け計量を待ってサンプルを搬送するのではなく、計量途中でサンプルを搬送して以後の食味・品位検定を開始するものであるから、次の荷口生産者の待ち時間を少なくすることができ、荷受の効率をはかることができる。
一方、平均的な荷受重量の場合には、満遍なくサンプルするものであって、サンプル穀物の抽出の偏りがなく信頼性を確保できる。
【0006】
【発明の実施の形態】
この発明の一実施例を図面に基づいて説明する。図は原料としての籾を荷受けして乾燥,調製処理する乾燥調製施設の一部を示し、荷受部1,サンプル抽出後のサンプル穀物検査部2,仕分けタンク部3等を示している。
上記のうち、荷受部1には、荷受毎に異なる荷受ホッパ4,4で受けることができるように複数のホッパを備え、該ホッパ4,4の荷受籾は、コンベアを介して1基の荷受計量機5に供給される構成である。荷受計量機5近傍には、穀物の流下部に出入りして所定穀物量をサンプリングするサンプラ6を設け、このサンプラ6に空気搬送器(サンプル搬送装置)7の筒状体を接続している。筒状体終端の空気搬送器7の下方には、サンプル分配器8を備え、分配穀物の一を自主検査装置9に、他を籾すり・粒選別装置10経由で内部品質検査装置11・外観品質検査装置12に供給する構成である。
【0007】
上記自主検査装置9は、従来公知の形態で、サンプル乾燥部と自主検査部とからなり、サンプル穀物を所定水分値に仕上げた後、脱ぷ処理して、整玄米と屑粒とに選別分離し、これらの重量割合をもって荷受穀物毎の歩留まりを求め、生産持込み者への金額換算データとする構成である。
籾すり・粒選別装置10は、サンプル分配器8の他のサンプルを受けて、籾すり・粒径選別し、整玄米を次段の内部品質検査装置11・外観品質検査装置12に供給する構成である。なお、籾すり装置としては遠心脱ぷ機を採用し、多少の高水分穀物に対応できるものとしている。13,13…は待機ボックスである。
【0008】
内部品質検査装置11は、一例として所謂食味計があり、非破砕状態で内部成分分析によって食味値に換算するものである。なお、内部品質検査装置11としてはこの内部成分の状況を個々に表す構成であってもよい。この内部品質検査装置11を通過した後、そのサンプルの一部が外観品質検査装置12に供給されて、外観品位、例えば着色粒、胴割れ粒、整粒等に区分され、その粒数割合が算出される構成である。上記内部成分分析には近赤外線照射により、外観品質測定には、可視光照射によって行うもので、従来公知の手段を採用できる。
【0009】
外観品質検査装置12を経由したサンプル粒及び、内部品質検査装置11を経由するも外観品質検査装置12に導入されないサンプルは、サンプルパック装置14で同一領域にパックされる構成である。
図2は、品質検査対象穀物の処理の別例であり、空気搬送器7下方には、サンプル分配器8の代わりに待機ボックス15,15を接続する構成とし、穀物は順次自主検査装置9に送られる。ここでの処理は前記のとおりであり、当該自主検査装置9で分離選別された整粒を、併設された内部品質検査装置11及び外観品質検査装置12に分配する検査用ホッパ16に供給すべく構成する。17のサンプルパック装置は、内部品質検査装置11及び外観品質検査装置12を経由した整粒と、前記自主検査装置9からの屑粒を順次パックできる構成としている。
【0010】
18,18…は原料タンクで、複数基備えられ、予めどのタンクにはどのランクの穀物を収容すべきかが設定されている。例えば、食味値良かつ品位良の場合はAタンクに、食味値標準かつ品位良ではBタンクに、食味値良かつ品位標準ではCタンクに、食味値,品位共標準ではDタンクに収容すべく設定されている。前記内部品質検査装置11及び外観品質検査装置12の検査結果を直ちに受けていずれのタンク18に移送すべきかが指定され、それに基づいて所定搬送系が駆動される構成である。
【0011】
前記荷受計量機5と上記原料タンク18,18…群との間には、流量調整タンク19,19を備える。なお、荷受計量機5から当該流量調整タンク19,19への搬送系20,20の起動・停止、及び流量調整タンク19,19から原料タンク18,18…への搬送系21,21…の起動・停止は後記制御部22が司る。この制御部22には、上記A〜Dの原料タンク毎に収容すべき食味・品位のランクが記憶されていて、内部品質検査装置11及び外観品質検査装置12の検査結果を受信して、いずれの搬送系20,20及び21,21…に起動・停止信号を出力するものである。
【0012】
図3は制御ブロック図を示し、制御部22は上記搬送系20,20および2121…への起動・停止信号出力のほか、荷受計量機5への作動信号、サンプラ6の作動信号、あるいは出力回路23を介してのサンプラ6から各内部品質検査装置11及び外観品質検査装置12へのサンプル搬送装置としての空気搬送器7の作動信号、サンプル分配器8の左右切換作動信号、籾すり・粒選別装置10作動信号、該内部品質検査装置11及び外観品質検査装置12等に作動出力する一方、荷受計量機5の計量信号、荷受量概算重量設定器24からの概算重量設定情報、内部品質検査装置11及び外観品質検査装置12からの各検査情報等を入力する構成である。
【0013】
次に上記サンプラ6の作動タイミングについて、荷口aにおける荷受穀物の上記荷受量概算重量設定器24からの概算重量w’(≒w)が前記流量調整タンク19の収容可能重量waよりも大きいときには、計量機5の計量重量wがあらかじめ設定した重量wcを越えると、サンプル穀物を所定重量を図例では5回繰り返しサンプリングすべく作動する構成としている。サンプラ6によるサンプリングが終了すると直ちに空気搬送器7を作動してサンプル穀物を自主検定装置9または内部品質検査装置11及び外観品質検査装置12用としての籾すり・粒選別装置10に供給する構成である(図4)。
【0014】
なお、上記概算重量w’の入力は、荷受ホッパ4投入前の車重から換算して自動入力する形態でもよく、生産者又は施設内作業員がキーボード入力してもよい。
一方、上記概算重量w’が流量調整タンク19の収容可能重量wa以下のときには、計量機5の計量開始と共にサンプラ6を所定タイミングで作動し、所定回数(図例では8回、又は所定重量を確保した時点)をもってサンプリングを終了し、その後空気搬送器7を作動してサンプル穀物を自主検定装置9または内部品質検査装置11及び外観品質検査装置12のための籾すり・粒選別装置10に供給するものである(図5)。
【0015】
上例の作用について説明する。
予め半乾燥、例えば水分値18%以下に乾燥された穀物(籾)がトラック等で搬送され、荷受ホッパ4に移される。荷受された穀物は、順次荷受計量機5に搬送され、荷口毎に荷受重量が計測される。荷受された穀物のうち、サンプラ6で約800gがサンプリング抽出される。サンプリングされた籾は、空気搬送器7,サンプル分配器8を経由し、400gずつ自主検査装置9用と、内部品質検査装置11・外観品質検査装置12用とに分けられ、夫々所定に供給される。
【0016】
上記サンプラ6での約800gのサンプル穀物の確保するための所要回数(時間)は、荷受流量調整タンク19の容量waと概算重量w’との比較によって、wa<w’のときは、当該サンプリング回数5回で上記サンプル穀物量を確保し、継続して計量機5が計量しながら空気搬送器7を作動してサンプル穀物を供給しうるものである(図6)。一方wa>w’のときは、所定タイミング毎にサンプラ6はサンプリングして端量信号出力、すなわち当該荷口が終了した時点でサンプル穀物を空気搬送器7で供給する。
【0017】
さて自主検査装置9に供給されたサンプル穀物は、所定水分値、例えば16%程度にまで乾燥され、次いで、脱ぷ・選別処理が施される。選別後の整粒重量を計量することにより、整粒歩留まりが算出され、荷受穀物全体の歩留まりに反映させて金額換算の根拠とされる。
一方、内部品質検査装置11・外観品質検査装置12用のサンプル穀物は、直ちに籾すり・粒選別装置10に供給され、遠心脱ぷ処理や粒径選別処理を受ける。その間の所要時間は約3分程度である。整玄米は検査用ホッパ16に供給され、大半の約300gが内部品質検査装置11としての食味計に供給され、余りのうち約30gが外観品質検査装置12としての品位計に供給される。整玄米を非破壊のまま近赤外線を照射して内部成分を計測しながら、予め作成した検量線等との比較により成分分析を行い食味値が求められる。また、外観品質検査装置側では、整玄米、胴割れ米、着色米等を光学的手段を用いて分類化し夫々の比率を算出し、予め規定された範囲のいずれにあるかを求めるものである。これらの処理はいずれもコンピュータ処理がなされるが、食味値判定に要する時間が約2分,品位測定に要する時間が約20秒である。従ってサンプリングから食味値・品位データ測定結果が算出されるまでに約6分程度要することとなる。
【0018】
さて、食味値・品位データ測定結果は、制御部22に出力される。制御部22は、当該測定結果の対象である荷受穀物aを計量毎に流量調整タンク19に送り込んで待機させており、食味値・品位データを入力すると、その内容からA〜Dのいずれのランクに該当するかを判断し、どの原料タンク18に投入すべきかを判定する。その判定結果に基づき、所定原料タンク18に移すべき搬送系21を起動する。
【0019】
よって、荷受計量機5容量よりも大なる荷受穀物が一挙に荷受されたとしても、荷受計量毎に流量調整タンク19側への搬送系20を動作させておくことにより、その位置でストック状態にして、原料タンク18への判定結果を待つことができ、次の荷受計量作業を中断させないため、全体の荷受時間を短縮できる。
また、流量調整タンク19の容量よりも大なる重量の穀物が荷受された場合には、荷受計量を待ってサンプル穀物を空気搬送器7で搬送するものとせず、計量途中で空気搬送器7にてサンプリング供給し、以後の自主検定や食味・品位検定を開始するものであるから、次の荷口生産者の待ち時間を少なくすることができ、荷受の効率をはかることができる。
【0020】
一方、平均的な荷受重量の場合には、万便なくサンプルするものであって、サンプル穀物の抽出の偏りがなく信頼性を確保できる。
なお、原料タンク18,18…には内部品質・外観品位の揃った穀物を収容しているため、以後の作業、例えば乾燥・調製行程における穀物管理が容易となる。
内部品質・外観品位の検出データが揃いそれらの総合判定によって、原料タンク18のいずれに投入するかが決定されるが、所定品質に達しない荷受穀物については、規格外品として流量調整タンク19から機外に排出(イ)される。
【0021】
上記の例では、半乾燥穀物を対象としたが、荷受穀物としては玄米であってもよく、また、半乾燥状態に至るものであるか否かを荷受計量機5等に付設した水分検出器の検出結果に基づき、次の流量調整タンク19にて待機後、異常に高い水分であって、検査サンプルとして適当でない場合にも規格外品として排出するものとしてもよい。この場合には、サンプラ6でのサンプリングを行わない前に水分検出結果を判断できる構成とするのがよいが、サンプリング後に判明したら、サンプル分配器8からの穀物を適宜回収する回収手段を設けるとよい。
【0022】
図2の場合には、自主検査装置6の穀物を利用しようとするから、サンプル穀物量を約半分にすることができるものである。また、内部品質検査と外観品質検査とを並列処理するから、所要時間が内部品質測定の要する時間(>外観品質検査時間)で済み、効率的である。
上例では、内部品質検査装置11と外観品質検査装置12の両者の検出結果に基づいて原料タンク18への仕分け処理を行う形態としたが、いずれか一方のみの検出結果に基づく仕分けでもよい。
【0023】
サンプラ6によるサンプリングの時期を計量開始直後とすると、前の荷口の残粒の影響を否めず、このため、図7では、荷受穀物が計量機5に投入された後一定時間経過後、あるいは所定の設定重量計量後からサンプラ6によるサンプリングを開始し、サンプル回数あるいはサンプル重量が所定以上となれば空気搬送器7を作動する構成としている。こうすることによって、上記残粒がなくなり、今回の荷口のサンプルを抽出でき、例え品位計など微量サンプルを分析するものにおいても前の荷口の影響を受けないで正確なサンプル分析が可能となる。

[Industrial application fields]
The present invention relates to a receiving grain processing facility .
[0002]
[Prior Art and Problems to be Solved by the Invention]
Conventionally, for example, in a grain drying preparation facility or a brown rice center that receives rice cake, a sample is taken from a measuring tank of a receiving weighing machine for each receiving grain, and the sampling amount and timing thereof are arbitrarily set. . In addition, the time required for processing the sampled sample grain is affected by the processing capacity of the equipment and the number of samples per hour, but in the case of cocoons, sample transport time, scouring / grain selection time, quality / taste measurement The total of time and sample grain discharge time is generally longer than the time required for receiving and weighing to be processed in a short time, i.e., the input time to the weighing machine, the weighing time, the sample grain extraction time, and the discharge time. Is needed.
[0003]
Therefore, there is a discrepancy when weighs the grains received in order and evaluates the sample, and the overall time required increases, and the loading port changes for each different producer, but the carry-in weight varies. .
In addition, since the weight of each consignment is different, there is a risk that if the sample is sampled immediately after the consignment changes, the sample grain of the previous consignment will be mixed.
[0004]
[Means for Solving the Problems]
Therefore, the present invention provides a plurality of load receiving hoppers, a flow rate adjusting tank for adjusting the flow rate of the received grain, a load receiving weighing machine for weighing the received grain for each different load receiving hopper , and a predetermined amount of grain from the load receiving weighing machine. A sampler that samples multiple times each time, a sample transport device that transports the sampled grain, a quality inspection device that inspects the quality of the sampled grain, and a grain based on the inspection information inspected by the quality inspection device In the receiving grain processing facility provided with a plurality of raw material tanks
A load receiver approximate weight setter is provided to set the approximate amount of the received grain. When the estimated load input to the load receiver approximate set weight is greater than the capacity that can be accommodated in the flow adjustment tank, the weight is measured by the receiver weighing machine. When the grain weight exceeds the preset weight, sampling starts with the sampler, and the sample transport device transports the sample during weighing.
Consignee Approximate weight is configured to operate at a predetermined timing sampler with the start of the metering when can accommodate weight or less of the flow rate adjusting tank, consignee grain processing facility, wherein the sample transport apparatus to perform the conveyance of the sample at the measurement ending The configuration is as follows.
[0005]
[Action and effect of the invention]
Because of the above configuration, when a grain with an approximate weight receiving weight larger than the capacity that can be accommodated in the flow adjustment tank is received, the sample is not transported after waiting for the weighing to be received. Since the subsequent taste / quality test is started, the waiting time of the next consignment producer can be reduced, and the efficiency of receiving goods can be improved.
On the other hand, in the case of an average load weight, the sample is uniformly sampled, and there is no bias in extracting the sample grain, and reliability can be ensured.
[0006]
DETAILED DESCRIPTION OF THE INVENTION

The figure shows a part of a drying preparation facility for receiving and drying and preparing the raw material as a raw material, and shows a receiving part 1, a sample grain inspection part 2 after sample extraction, a sorting tank part 3, and the like.
Among the above, the cargo receiving portion 1 is provided with a plurality of hoppers so that different cargo receiving hoppers 4 and 4 can receive each cargo receiving, and the cargo receiving rods of the hoppers 4 and 4 receive one cargo receiving device via a conveyor. This is a configuration supplied to the weighing machine 5. In the vicinity of the load receiving and weighing machine 5, a sampler 6 that enters and exits the grain flow lower part and samples a predetermined grain amount is provided, and a cylindrical body of an air carrier (sample carrier device) 7 is connected to the sampler 6. A sample distributor 8 is provided below the air carrier 7 at the end of the cylindrical body. One of the distributed grains is sent to the self-inspection apparatus 9 and the other is crushed and granulated by the internal quality inspection apparatus 11 via the grain sorting apparatus 10. This is a configuration for supplying to the quality inspection device 12.
[0007]
The self-inspection device 9 is a conventionally known form, and includes a sample drying unit and a self-inspection unit. After finishing the sample grain to a predetermined moisture value, the sample grain is depulverized and separated into conditioned rice and waste grains. Then, the yield for each consigned grain is obtained with these weight ratios, and the result is converted into monetary data for the producer.
The rice bran / grain sorting device 10 receives other samples of the sample distributor 8, sorts and sorts the grain, and supplies the conditioned rice to the internal quality inspection device 11 and appearance quality inspection device 12 in the next stage. It is. In addition, a centrifugal dehuller is adopted as a scouring device, and it can cope with some high moisture grains. 13, 13... Are standby boxes.
[0008]
The internal quality inspection apparatus 11 has a so-called taste meter as an example, and converts it into a taste value by internal component analysis in a non-crushed state. The internal quality inspection device 11 may be configured to individually represent the status of the internal components. After passing through the internal quality inspection device 11, a part of the sample is supplied to the appearance quality inspection device 12, and is classified into appearance quality, for example, colored particles, shell cracking particles, sized particles, etc. This is a calculated configuration. The internal component analysis is performed by near infrared irradiation, and the appearance quality measurement is performed by visible light irradiation. Conventionally known means can be employed.
[0009]
Sample grains that have passed through the appearance quality inspection apparatus 12 and samples that have not been introduced into the appearance quality inspection apparatus 12 through the internal quality inspection apparatus 11 are packed in the same region by the sample pack apparatus 14.
FIG. 2 shows another example of the processing of the quality inspection target grain. In the lower part of the air carrier 7, standby boxes 15 and 15 are connected instead of the sample distributor 8, and the grains are sequentially supplied to the self-inspection apparatus 9. Sent. The processing here is as described above, and the sized particles separated and selected by the self-inspection device 9 should be supplied to the inspection hopper 16 that distributes to the internal quality inspection device 11 and the appearance quality inspection device 12 provided together. Constitute. The sample packing device 17 has a configuration in which the sized particles passed through the internal quality inspection device 11 and the appearance quality inspection device 12 and the waste particles from the self-inspection device 9 can be packed sequentially.
[0010]
18 ... in the raw material tank, provided several groups, is set either to be accommodated which rank cereals in advance which tank. For example, if the taste value is good and the quality is good, it should be stored in the A tank, if the taste value is standard and good quality, the tank is B, if the taste value is good and the quality standard is in the C tank, and the taste value and quality are both in the D tank. Is set. The inspection result of the internal quality inspection device 11 and the appearance quality inspection device 12 is immediately received, it is specified which tank 18 should be transferred, and a predetermined transport system is driven based on this.
[0011]
Between the cargo receiving weighing machine 5 and the raw material tanks 18, 18,... In addition, starting / stopping of the transfer systems 20 and 20 from the load receiving / measuring machine 5 to the flow rate adjusting tanks 19 and 19 and starting of the transfer systems 21, 21... From the flow rate adjusting tanks 19 and 19 to the raw material tanks 18, 18. The stop is controlled by the control unit 22 described later. The control unit 22 stores the rank of taste and quality to be accommodated for each of the raw material tanks A to D, receives the inspection results of the internal quality inspection device 11 and the appearance quality inspection device 12, and The start / stop signals are output to the transport systems 20, 20, 21, 21,.
[0012]
FIG. 3 shows a control block diagram, in which the control unit 22 outputs the start / stop signal output to the transport systems 20, 20 and 21 , ..., The operation signal to the load receiving weighing machine 5, the operation signal of the sampler 6, or The operation signal of the air carrier 7 as the sample carrier device from the sampler 6 to each internal quality inspection device 11 and the appearance quality inspection device 12 via the output circuit 23, the left / right switching operation signal of the sample distributor 8, The operation signal is output to the grain sorting device 10 operation signal, the internal quality inspection device 11 and the appearance quality inspection device 12, and the like. The weighing signal of the load receiving weighing machine 5, the approximate weight setting information from the load receiving amount approximate weight setting device 24, the internal quality. Each inspection information from the inspection device 11 and the appearance quality inspection device 12 is input.
[0013]
Next, regarding the operation timing of the sampler 6, when the approximate weight w ′ (≈w) from the load receiving weight approximate weight setting unit 24 of the cargo receiving grain at the loading port a is larger than the allowable weight wa of the flow rate adjusting tank 19, When the weighing weight w of the weighing machine 5 exceeds a preset weight wc, the sample grain is configured to operate to sample a predetermined weight repeatedly five times in the illustrated example. Immediately after the sampling by the sampler 6 is completed, the air carrier 7 is operated to supply the sample grain to the self-verification apparatus 9 or the internal quality inspection apparatus 11 and the mortar / grain selection apparatus 10 for the appearance quality inspection apparatus 12. Yes (Fig. 4).
[0014]
The input of the approximate weight w ′ may be automatically input in terms of the vehicle weight before the load receiving hopper 4 is introduced, or may be input by a producer or a facility worker.
On the other hand, when the approximate weight w ′ is equal to or less than the weight wa that can be accommodated in the flow rate adjusting tank 19, the sampler 6 is operated at a predetermined timing when the weighing machine 5 starts weighing, and the predetermined number of times (in the illustrated example, eight times or a predetermined weight is set). Sampling is completed at the time of securing), and then the air carrier 7 is operated to supply the sample grain to the self-verification apparatus 9 or to the mortar / grain sorting apparatus 10 for the internal quality inspection apparatus 11 and the appearance quality inspection apparatus 12. (FIG. 5).
[0015]
The operation of the above example will be described.
Grains (rice cakes) that have been semi-dried in advance, for example, dried to a moisture value of 18% or less, are conveyed by a truck or the like and transferred to the cargo receiving hopper 4. The received grain is sequentially conveyed to the load receiving weighing machine 5 and the received weight is measured for each load port. About 800 g of the received grain is sampled and extracted by the sampler 6. The sampled soot is divided into a self-inspection device 9, an internal quality inspection device 11, and an appearance quality inspection device 12 by 400 g each via an air carrier 7 and a sample distributor 8, and each is supplied in a predetermined manner. The
[0016]
The number of times (time) required to secure approximately 800 g of sample grain in the sampler 6 is determined by comparing the capacity wa of the receiving flow rate adjusting tank 19 and the approximate weight w ′ when wa <w ′. The amount of the sample grain is ensured by the number of times five times, and the sample grain can be supplied by operating the air carrier 7 while the weighing machine 5 continuously measures (FIG. 6). On the other hand, when wa> w ′, the sampler 6 samples at every predetermined timing and outputs the end amount signal, that is, the sample grain is supplied by the air conveyer 7 when the cargo exit is completed.
[0017]
Now, the sample grain supplied to the self-inspection apparatus 9 is dried to a predetermined moisture value, for example, about 16%, and then subjected to a deflation / sorting process. By measuring the sized weight after sorting, the sized yield is calculated and reflected in the yield of the entire receiving grain, which is used as the basis for monetary conversion.
On the other hand, the sample grains for the internal quality inspection device 11 and the appearance quality inspection device 12 are immediately supplied to the scouring / grain sorting device 10 and subjected to centrifugal de-pulverization processing and particle size sorting processing. The required time in the meantime is about 3 minutes. The brown rice is supplied to the inspection hopper 16, most of about 300 g is supplied to the taste meter as the internal quality inspection device 11, and about 30 g of the remainder is supplied to the quality meter as the appearance quality inspection device 12. While measuring the internal components by irradiating the near-infrared rays with the non-destructed brown rice being measured, the components are analyzed by comparison with a calibration curve or the like prepared in advance, and the taste value is obtained. In addition, the appearance quality inspection apparatus side classifies the cooked brown rice, torso cracked rice, colored rice, etc. using optical means, calculates the ratio of each, and finds which one is in a predefined range. . All of these processes are computer processes, and the time required for taste value determination is about 2 minutes, and the time required for quality measurement is about 20 seconds. Therefore, it takes about 6 minutes from the sampling until the taste value / quality data measurement result is calculated.
[0018]
The taste value / quality data measurement result is output to the control unit 22. The control unit 22 sends the consignment grain a, which is the object of the measurement result, to the flow rate adjustment tank 19 every time it is weighed. When the taste value / quality data is input, any one of ranks A to D is determined. To determine which material tank 18 should be charged. Based on the determination result, the transfer system 21 to be transferred to the predetermined raw material tank 18 is activated.
[0019]
Therefore, even if the receiving grain larger than the capacity of the receiving / weighing machine 5 is received at once, by moving the transfer system 20 to the flow rate adjustment tank 19 side for each receiving / weighing, the stock state is made at that position. Thus, the determination result to the raw material tank 18 can be waited, and the next receiving and weighing operation is not interrupted, so that the entire receiving time can be shortened.
Further, when a grain having a weight larger than the capacity of the flow rate adjusting tank 19 is received, the sample grain is not transported by the air transporter 7 after waiting for the load receiving measurement, and is sent to the air transporter 7 during the weighing. Sampling and supply, and the subsequent self-assessment and taste / quality test are started. Therefore, the waiting time of the next consignment producer can be reduced, and the efficiency of receiving goods can be improved.
[0020]
On the other hand, in the case of an average load weight, the sample is sampled without any convenience, and there is no bias in extracting the sample grain, and reliability can be ensured.
In addition, since the raw material tanks 18, 18... Contain grains having the same internal quality and appearance quality, grain management in subsequent operations, for example, drying / preparation steps, is facilitated.
The internal quality / appearance quality detection data is complete, and the overall judgment determines which of the raw material tanks 18 will be charged. It is discharged (b) outside the machine.
[0021]
In the above example, semi-dried cereals are targeted. However, as a consignment grain, brown rice may be used, and a moisture detector attached to the consignment weighing machine 5 or the like to determine whether or not it reaches a semi-dry state. Based on this detection result, after waiting in the next flow rate adjustment tank 19, even when the moisture is abnormally high and is not suitable as a test sample, it may be discharged as a nonstandard product. In this case, it is preferable that the moisture detection result can be determined before the sampling by the sampler 6 is performed. However, if it is found after the sampling, a collecting means for appropriately collecting the grain from the sample distributor 8 is provided. Good.
[0022]
In the case of FIG. 2, since the grain of the self-inspection apparatus 6 is to be used, the amount of sample grain can be reduced to about half. Further, since the internal quality inspection and the appearance quality inspection are processed in parallel, the time required for the internal quality measurement (> appearance quality inspection time) is sufficient, which is efficient.
In the above example, the sorting process to the raw material tank 18 is performed based on the detection results of both the internal quality inspection device 11 and the appearance quality inspection device 12, but the sorting may be based on only one of the detection results.
[0023]
If the sampling time by the sampler 6 is immediately after the start of weighing, the influence of the residual grain of the previous cargo port cannot be denied. For this reason, in FIG. Sampling by the sampler 6 is started after the set weight is measured, and when the number of samples or the sample weight exceeds a predetermined value, the air carrier 7 is operated. By doing so, the residual particles can be eliminated, and the sample of the present consignment can be extracted, and an accurate sample analysis can be performed without being influenced by the previous consignment even in the case of analyzing a trace amount sample such as a quality meter.
