The alignment of the cavity (21) next to the sensor (40) is performed due to the end of the course of movement of the structure (20).
[036] O descarte dos grãos, que já passaram pela mediação do sensor (40), ocorre no ponto extremo do movimento de expulsão da estrutura (20) onde a cavidade (21) passa pela projeção (31), assim a cavidade (21) fica“sem fundo” e o produto que estava dentro retorna ao fluxo da máquina.  The disposal of the grains, which have already passed through the sensor 40, occurs at the extreme point of the ejection movement of the structure 20 where the cavity 21 passes through the projection 31, thus the cavity 21 ) becomes "bottomless" and the product that was inside returns to the flow of the machine.
[037] Quando inicia o caminho de volta para dentro do amostrador, a cavidade (21) reinicia novamente o ciclo, devido a ficar posicionada junto a projeção (31) (o que dá fundo), retendo o produto e levando para ser medido pelo leitor.  When the path starts back into the sampler, the cavity (21) restarts the cycle, due to being positioned next to the projection (31) (which gives background), retaining the product and leading to be measured by the reader.
[038] A estrutura (10) disposta junto ao fluxo de grãos mantém parte do fluxo constante junto abertura (12). Assim, quando o sistema eletrónico é acionado o motor (50) movimenta a estrutura (20) para fora da abertura (12), captando uma amostra que retorna junto a estrutura (20) até o alinhamento com o sensor (40) que realiza as devidas medições. Para se obter o valor especifico de brancura dos grãos é realizada a medição de 10 (dez) amostras, sendo obtida uma média através do calculo realizado pela placa de controle do equipamento.  The structure (10) disposed adjacent to the grain stream maintains part of the constant flow together aperture (12). Thus, when the electronic system is actuated, the motor 50 moves the structure 20 out of the aperture 12, picking up a sample that returns along the structure 20 to alignment with the sensor 40 that performs the measurements. In order to obtain the specific value of grain whiteness, 10 (ten) samples are measured and a mean is obtained by the calculation performed by the equipment control board.
[039] O sistema eletrónico do equipamento é composto por uma primeira placa eletrónica interligada ao sensor de cores (40) e seus periféricos, sendo que cada fabricante de brunidores e polidores possuem diferentes maneiras de regular a máquina para polir mais ou menos, deixando o produto mais branco ou menos branco. Assim, são instalados periféricos (atuadores elétricos) que fazem esses ajustes, de acordo com as necessidades detectadas pelo medidor de brancura. A segunda placa eletrónica de controle compõe a parte de alimentação, controle e comunicação do equipamento. The electronic system of the equipment is composed of a first electronic board interconnected to the color sensor 40 and its peripherals, each manufacturer of burners and polishers having different ways of regulating the machine to polish more or less, leaving the whiter or less white product. Thus, installed peripherals (electric actuators) that make these adjustments, according to the needs detected by the whiteness meter. The second electronic control board comprises the power supply, control and communication part of the equipment.
[040] O sensor de brancura (40) possui duas placas internas em seu corpo (não demostrado), sendo que uma delas lê o valor de cor e a outra faz a comunicação.  The whiteness sensor (40) has two internal plates in its body (not shown), one of which reads the color value and the other one communicates.
[041] As placas eletrónicas ficam envolvidas por um encapsulamento que fica acoplado junto ao sensor (40), assim o sensor (40) dotado pelas placas que se conecta ao atuador elétrico por meio de cabos e ao sistema de automação por meio de rede ethernet.  [041] The electronic boards are surrounded by an encapsulation which is coupled next to the sensor (40), thus the sensor (40) provided by the plates which is connected to the electric actuator by means of cables and to the automation system via an ethernet network .
[042] Através de rede RS485, com protocolo de comunicação Modbus RTU a informação é disponibilizada para qualquer sistema de automação.  [042] Through the RS485 network, with communication protocol Modbus RTU the information is made available to any automation system.
[043] A alimentação do medidor de brancura deve se dá em 24 Vdc e seu consumo estimado é de aproximadamente 100 mA.  [043] The power supply of the whiteness meter should be given at 24 Vdc and its estimated consumption is approximately 100 mA.
[044] O equipamento medidor de brancura aplicado nas etapas de beneficiamento de grãos e cereais é disposto no meio do fluxo dos grãos, apresentando as seguintes caraterísticas de funcionamento:  [044] The whiteness metering equipment applied in the grain and cereal processing stages is arranged in the middle of the grain flow, having the following operating characteristics:
[045] A estrutura (10) dotada por uma placa defletor (11) mantém constante o fluxo de grãos junto à abertura (12); The structure (10) provided by a deflector plate (11) keeps the flow of grains constant close to the aperture (12);
[046] Quando o equipamento esta em repouso, sem realizar as medições, a estrutura (20) se mantém parada junto à base (30);  [046] When the equipment is at rest, without taking the measurements, the structure (20) remains stationary next to the base (30);
[047] Quando o equipamento é acionado a estrutura (20) é movimentada horizontalmente em direção abertura (12) e projeção (31) de forma posicionar a cavidade (21) junto ao fluxo de grãos, captando uma amostra e retorno para a posição de repouso; [048] A estrutura (20) ao captar amostra retorna a posição de repouso alinhando a cavidade (21) junto ao sensor (40), de modo a permitir a medição de brancura dos grãos. Para se obter o valor especifico de brancura dos grãos é realizada a medição de 10 (dez) amostras, sendo obtida uma média através do calculo realizado pela placa de controle do equipamento. When the apparatus is actuated the structure 20 is moved horizontally toward the aperture 12 and projection 31 to position the cavity 21 adjacent to the grain flow, picking up a sample and returning to the position rest; The sample capture structure 20 returns to the rest position by aligning the cavity 21 adjacent to the sensor 40 so as to allow measurement of whiteness of the beans. In order to obtain the specific value of grain whiteness, 10 (ten) samples are measured and a mean is obtained by the calculation performed by the equipment control board.
[049] Desta forma, é objeto do presente modelo de utilidade, uma disposição construtiva em equipamento medidor de brancura que descreve uma estrutura (20) de movimentação horizontal dotada por uma cavidade (21) que se movimenta em sentido a abertura (12) e projeção (31) disposta abaixo da placa defletora (11) que esta fixada junto ao fluxo de grãos, permitindo que a estrutura colete pequenas amostras de grãos para a medição do sensor que realiza a medição no nível de brancura e, após a medição direciona amostra novamente para o fluxo dos grãos. O equipamento é gerenciado por uma placa de controle que recebe as informações do sensor e disponibiliza os dados ao sistema de automação industrial, informando a intensidade de brancura da amostra, de forma automatizada.  An object of the present utility model is thus a constructive arrangement in whiteness measuring apparatus which describes a horizontal movement structure (20) provided by a cavity (21) that moves in the direction of the aperture (12) and projection (31) disposed below the baffle plate (11) which is attached to the grain stream, allowing the structure to collect small grain samples for the measurement of the sensor performing the measurement at the whiteness level and, after measurement, directs sample again to the grain flow. The equipment is managed by a control board that receives the information from the sensor and makes the data available to the industrial automation system, informing the whiteness intensity of the sample, in an automated way.
