Description

DISPOSITIVO DOSADOR  DOSING DEVICE
A presente patente de invenção refere-se a um dispositivo dosador dotado de comportas, utilizado com qualquer tipo de produto, seja ele granulado ou em pó.  The present invention relates to a flooded metering device used with any type of product, whether granulated or powdered.
Histórico da inovação  Innovation History
É do conhecimento do homem da técnica a utilização de dosadores acoplados a máquinas empacotadeiras que permitem o ajuste da quantidade do produto a ser empacotado.  It is known to the man in the art to use feeders coupled to wrapping machines that allow adjustment of the amount of product to be packaged.
Dentre os dosadores conhecidos tem-se o tipo carrossel de canecas; o de caneca única com gavetas; e, o de rosca. Cada dosador é adequado a um tipo de produto, que pode ser em pó ou granulado, tais como cereais, açúcar ou farináceos em pó.  Among the known feeders is the mug carousel type; the one with single drawer mug; and the threaded one. Each feeder is suitable for a type of product, which may be powdered or granulated, such as cereals, sugar or powdery flours.
O dosador do tipo carrossel de canecas é mais utilizado para produtos granulados. Ele compreende um funil para receber o produto a ser medido e empacotado; abaixo do funil há uma plataforma giratória dotada de uma pluralidade de recipientes, cada um dos quais, a seu tempo, é alinhado à saída do referido funil, quando do giro da plataforma, preenchendo-o com o produto. Abaixo da plataforma giratória há uma base com uma abertura para a saída do produto para empacotamento. Conforme a referida plataforma gira, um de seus recipientes é alinhado com a abertura da dita base, liberando o produto do recipiente. Assim, o controle da quantidade a empacotar é feito pelo volume das canecas que, após serem preenchidas, são movidas sob o giro da plataforma, até encontrar a saída posicionada na base do dosador, liberando todo seu conteúdo para empacotamento.  The Carousel Mug Dispenser is most commonly used for granular products. It comprises a funnel for receiving the product to be measured and packaged; below the funnel is a turntable provided with a plurality of containers, each of which, in time, is aligned at the outlet of said funnel as the platform is rotated, filling it with the product. Below the turntable is a base with an opening for the exit of the packaging product. As said platform rotates, one of its containers is aligned with the opening of said base, releasing the product from the container. Thus, the control of the quantity to be packaged is made by the volume of the mugs that, after being filled, are moved under the rotation of the platform, until they find the exit positioned in the base of the doser, releasing all its contents for packing.
O dosador de caneca única com gavetas é também utilizado para produtos granulares. De forma semelhante ao anterior, a medição é feita com o preenchimento de um recipiente que é posicionado entre um funil abastecido com o material a medir, e uma saída do material para empacotamento. O dosador compreende ainda duas comportas, uma superior e outra inferior ao recipiente, que funcionam como gavetas que fecham ou abrem a passagem do funil para o recipiente, e do recipiente para a saída. A medição é então feita pelo volume do recipiente, que é preenchido ao se manter a comporta inferior fechada e a superior aberta para receber o material do funil. Ao se completar o recipiente com o material, fecha-se a comporta superior e em seguida abre-se a inferior, liberando o material para empacotamento. O dosador volumétrico de rosca é mais indicado para produtos em pó ou farináceos pois permite uma regulagem mais fina da quantidade medida. Ele compreende um funil receptor do produto e o direciona a um segundo funil, que por sua vez é dotado de um prolongamento tubular inferior com uma rosca dosadora interna, que carrega o produto entre seus filetes até uma abertura inferior do referido prolongamento tubular. Assim, ao se girar dita rosca, o produto retido entre seus filetes é transportado ao longo do prolongamento tubular até sua saída, sendo então despejado para empacotamento. O segundo funil compreende ainda um agitador que avança até o início da rosca dosadora, facilitando o posicionamento do produto entre seus filetes. Assim, a dosagem é feita em função do número de voltas que a rosca realiza, quanto mais voltas, maior é a quantidade de produto que avança até a saída do prolongamento tubular onde é liberado. Por exemplo, ao se escolher uma quantidade de produto a empacotar, deve-se ajustar o número de voltas ou fração de voltas da rosca necessárias para que tal volume seja despejado. The single drawer mug dispenser is also used for granular products. Similarly to the above, the measurement is made by filling a container that is positioned between a funnel filled with the material to be measured and an outlet of the packaging material. The dispenser further comprises two floodgates, one upper and one lower than the container, which function as drawers that close or open the passage from the funnel to the container and from the container to the outlet. The measurement is then made by the volume of the container, which is filled by keeping the lower gate closed and the upper gate open to receive the funnel material. Upon completion of the container with the material, the upper gate is closed and then the lower one opens, freeing the material for packaging. The volumetric screw feeder is more suitable for powder or flour products because it allows a finer adjustment of the measured quantity. It comprises a product receiving funnel and directs it to a second funnel, which in turn is provided with a lower tubular extension with an internal metering screw thread which carries the product between its fillets to a lower opening of said tubular extension. Thus, by turning said thread, the product retained between its threads is transported along the tubular extension until its exit, and is then dumped for packaging. The second funnel further comprises an agitator that advances to the beginning of the dosing thread, facilitating the positioning of the product between its fillets. Thus, the dosage is made as a function of the number of turns that the thread makes, the more turns, the greater the amount of product that advances to the exit of the tubular extension where it is released. For example, when choosing a quantity of product to package, you must adjust the number of turns or fraction of turns of the thread required for such volume to be dumped.
Ocorre que cada um desses dosadores é adequado a um tipo de produto, não sendo possível utilizar um único dosador para produtos diferentes, apresentados em pó ou granulados.  It happens that each of these dosers is suitable for one type of product, and it is not possible to use a single doser for different products, presented in powder or granules.
Assim, a fim de solucionar esse inconveniente foi desenvolvido o presente dispositivo dosador dotado de comportas que pode ser utilizado com qualquer tipo de produto, seja ele granulado ou em pó.  Thus, in order to remedy this drawback, the present gated dosing device has been developed which can be used with any type of product, whether granulated or powdered.
É um outro objetivo da presente invenção, um dispositivo dosador de comportas de construtividade simples e que possibilita uma regulagem precisa da quantidade de produto a ser liberada para empacotamento.  It is another object of the present invention, a simple constructivity gate metering device which enables precise regulation of the amount of product to be released for packaging.
É ainda um outro objetivo da presente invenção, um dispositivo dosador cujas comportas têm seu funcionamento automatizado, o que agiliza o sistema de empacotamento.  It is yet another object of the present invention, a metering device whose gates have their automated operation, which speeds up the packaging system.
A fim de melhor explicar os detalhes da presente invenção são apresentadas a seguir algumas figuras esquemáticas, cujas dimensões e proporções não são necessariamente as reais, pois elas têm a finalidade de ilustrar didaticamente seus diversos aspectos, cuja abrangência de proteção está determinada apenas pelo escopo das reivindicações anexas.  In order to better explain the details of the present invention, some schematic figures are given below, whose dimensions and proportions are not necessarily the actual ones, as they are intended to illustrate didactically their various aspects, whose scope of protection is determined only by the scope of the attached claims.

Descrição da configuração ilustrada  Description of illustrated configuration
Conforme ilustrado nas figuras 1 a 4, a presente patente de invenção refere-se a um dispositivo dosador com comportas (1 ) formado por uma estrutura verticalizada que compreende um funil receptor de produtos (2) e um prolongamento tubular (20) inferior, sendo a abertura inferior do prolongamento tubular (20) fechada por um par de comportas primárias (21 ) articuláveis por meio de um mecanismo de acionamento (A)(melhor ilustradas na figura 2); e compreende ainda um elemento tubular (3) ao redor do prolongamento (20), cuja abertura inferior é posicionada abaixo da abertura do prolongamento (2), e é fechada por um par de comportas secundárias (31 ) articuláveis por meio do mecanismo de acionamento (A) que, ao serem abertas liberam o produto retido entre as comportas primárias (21 ) e secundárias (31) para empacotamento.  As illustrated in Figures 1 to 4, the present invention relates to a gate metering device (1) formed by a vertical structure comprising a product receiving funnel (2) and a lower tubular extension (20), being the lower opening of the tubular extension (20) closed by a pair of pivotable primary gates (21) by means of a drive mechanism (A) (better illustrated in figure 2); and further comprises a tubular element (3) around the extension (20), the lower opening of which is positioned below the extension opening (2), and is closed by a pair of secondary gates (31) hinged by means of the drive mechanism. (A) which, upon opening, release the product retained between the primary (21) and secondary (31) gates for packaging.
Dito elemento tubular (3) é fixado a um suporte (11 ) que é conectado a uma porca (15) rosqueada a uma rosca sem fim vertical (12), de forma que as posições verticais do elemento tubular (3) e das comportas secundárias (31 ) possam ser alteradas de forma a permitir o controle da quantidade de produto a ser empacotado. O nível da altura do elemento tubular (3) é ajustado conforme o afastamento ou aproximação de sua saída inferior em relação à saída inferior do prolongamento (20), de forma a permitir uma retenção maior ou menor de volume de produtos entre suas comportas secundárias (31 ) e primárias (21 ). Assim, o produto posicionado no funil (2) desce ao longo do prolongamento (20) ficando ali retido por suas comportas primárias (21 ). Ao se liberar a abertura das comportas primárias (21 ) o produto continua descendo até encontrar as comportas secundárias (31 ) do elemento tubular (3), que impedem o produto de continuar descendo. Quando o produto preenche o espaço entre as comportas primárias (21 ) e secundárias (31 ), fecham-se as comportas primárias (21 ) do prolongamento (20) de forma a impedir que o produto continue a cair; abrindo-se em seguida as comportas secundárias (31 ), que assim liberam o produto para o empacotamento. As comportas primárias (21 ) e secundárias (31 ) basculam para a abertura ou fechamento das saídas do prolongamento (20) e do elemento tubular (3), respectivamente. Ditas comportas primárias (21 ) e secundárias (31 ) são acionadas por um mecanismo de acionamento (A). O mecanismo de acionamento (A) compreende pistões (8) e (9) conectados por meio de alavancas (80) e (90), respectivamente, que têm um suporte intermediário (81 ) e (91) fixados em qualquer local da estrutura do dosador (1 ) que possibilite a formação de uma haste alavancada que movimenta as comportas primárias (21 ) e secundárias (31 ), particularmente, em uma placa (10) posicionada na base do funil (2) e no suporte (11 ) do elemento tubular (3); as alavancas (80) e (90) têm suas extremidades opostas às extremidades conectadas aos pistões (8) e (9), na forma de garfos (82, 92) cujas extremidades livres são conectadas aos eixos (212) e (312) das comportas (21 ) e (31 ), por meio de braços (83) e (93), de forma a mover as comportas (21 ) ou (31 ), de cada par, simultaneamente. Said tubular element (3) is fixed to a support (11) which is connected to a nut (15) threaded to a vertical endless thread (12), such that the vertical positions of the tubular element (3) and the secondary gates (31) may be amended to allow control of the quantity of product to be packaged. The height level of the tubular member (3) is adjusted to the extent that its lower outlet is spaced or approached from the lower outlet of the extension (20) so as to allow a greater or lesser volume retention between its secondary gates ( 31) and primary (21). Thus, the product positioned in the funnel (2) descends along the extension (20) and is retained there by its primary floodgates (21). By releasing the opening of the primary gates (21) the product continues to descend until it encounters the secondary gates (31) of the tubular element (3) which prevent the product from further descending. When the product fills the gap between the primary (21) and secondary (31) gates, the primary (21) gates of the extension (20) are closed to prevent the product from continuing to fall; then opening the secondary gates 31, which thus release the product for packaging. The primary (21) and secondary (31) gates swing to open or close the extension (20) and tubular element (3) outlets, respectively. Said primary (21) and secondary (31) gates are driven by a drive mechanism (A). The drive mechanism (A) comprises pistons (8) and (9) connected by levers (80) and (90), respectively, which have an intermediate support (81) and (91) attached to any location of the housing structure. (1) that enables the formation of a levered rod that moves the primary (21) and secondary (31) gates, particularly in a plate (10) positioned at the base of the funnel (2) and the support (11) of the element tubular (3); the levers (80) and (90) have their ends opposite the ends connected to the pistons (8) and (9), in the form of forks (82, 92) whose free ends are connected to the axes (212) and (312) of the gates 21 and 31 by means of arms 83 and 93 to move the gates 21 or 31 of each pair simultaneously.
As comportas primárias (21 ) e secundárias (31 ) compreendem hastes laterais superiores (211 ) e (311 ) que avançam até o prolongamento (20) e elemento tubular (3), onde são conectadas de forma a poder girar em torno de tal ponto de conexão (213, 313), entre uma posição de abertura e outra de fechamento das saídas do prolongador (20) e do elemento tubular (3), respectivamente.  The primary (21) and secondary (31) gates comprise upper side rods (211) and (311) which advance to the extension (20) and tubular member (3), where they are pivotally connected at such a point. (213, 313), between an opening and closing position of the protractor (20) and tubular element (3) outlets, respectively.
Segundo exemplo ilustrado na figura 3, o pistão (8), responsável pela movimentação das comportas primárias (21 ), é posicionado acima da placa (10) e a alavanca (80) é voltada para baixo, fazendo com que as comportas primárias (21 ) sejam abertas, quando a haste do pistão (8) avança, e sejam fechadas, quando a haste do pistão (8) recua.  According to the example illustrated in figure 3, the piston (8), which is responsible for moving the primary gates (21), is positioned above the plate (10) and the lever (80) is turned downwards, causing the primary gates (21) ) are opened when the piston rod (8) advances, and are closed when the piston rod (8) recedes.
Ainda no exemplo ilustrado, o pistão (9), responsável pela movimentação das comportas secundárias (31 ), é disposto de forma que a alavanca (90) fique direcionada para cima, fazendo com que ditas comportas secundárias (31 ) sejam abertas, quando a haste do pistão (9) recua, e sejam fechadas, quando a haste do pistão (9) avança.  Still in the illustrated example, the piston (9), responsible for moving the secondary gates (31), is arranged so that the lever (90) is directed upwards, causing said secondary gates (31) to be opened when the piston rod (9) recoils and is closed when piston rod (9) advances.
O posicionamento dos pistões (8) e (9) pode ser invertido, o que propicia uma inversão no movimento das comportas primárias (21 ) e secundárias (31 ).  The positioning of the pistons (8) and (9) can be reversed, which provides a reversal in the movement of the primary (21) and secondary (31) gates.
Assim ao se abrir as comportas primárias (21 ), os produtos caem por gravidade até o elemento tubular (3), onde ficam retidos pelas comportas secundárias (31) preenchendo o espaço acima delas. Fecham-se então as comportas primárias (21 ), e em seguida abrem-se as comportas secundárias (31 ), liberando o produto retido entre elas, que passa pelo funil (7), seguindo para empacotamento. O ciclo de dosagem se repete com o fechamento das comportas secundárias (31 ) seguido da abertura das comportas primárias (21 ), permitindo novo acúmulo de produto entre elas, para posterior liberação para empacotamento. Thus when opening the primary gates (21), the products fall by gravity to the tubular element (3), where they are retained by the secondary gates (31) filling the space above them. Then close the primary gates (21), and then the secondary gates (31) are opened, releasing the product retained between them, which passes through the funnel (7), proceeding for packaging. The dosing cycle is repeated with the closing of the secondary gates (31) followed by the opening of the primary gates (21), allowing new product accumulation between them, for later release for packaging.
Conforme ilustrado nas figuras anexas, o funil receptor (2) é dotado de um chapéu cónico (23), acima da entrada do prolongamento (20) e afastada dele, de forma a evitar o acúmulo de material no centro do funil (2) e o excesso de pressão nas comportas primárias (21 ). De maneira preferencial, o chapéu (23) compreende um tubo de respiro (22) que o atravessa, evitando a geração de vácuo entre o chapéu (23) e a saída do funil (2) para o prolongador (20), garantindo que o produto desça pelo funil receptor (2) por gravidade.  As illustrated in the accompanying figures, the receiving funnel (2) is provided with a conical hat (23) above and away from the extension inlet 20 to prevent material accumulation in the center of the funnel (2) and excess pressure in the primary gates (21). Preferably, the hat (23) comprises a breather tube (22) through it, preventing the generation of vacuum between the hat (23) and the funnel outlet (2) to the protractor (20), ensuring that the down the receiver funnel (2) by gravity.
O dosador (1 ) compreende ainda um funil inferior de despejo (7) posicionado na direção do elemento tubular (3), e uma cobertura (5) ao redor do elemento tubular (3) que avança até o funil (7), de forma a não expor o produto quando ele é liberado pelas comportas secundárias (31 ) do elemento tubular (3) até o funil (7).  The dispenser (1) further comprises a lower dump funnel (7) positioned towards the tubular member (3), and a cover (5) around the tubular member (3) which advances to the funnel (7) so do not expose the product when it is released by the secondary gates (31) of the tubular element (3) to the funnel (7).
O presente dosador com comportas (1 ) compreende ainda um par de barras verticais (6), ao longo das quais deslizam abraçadeiras (50) que são conectadas à cobertura (5). As abraçadeiras (50) são travadas às barras (6) por qualquer meio conhecido, tal como parafusos (51 ), que atravessam as abraçadeiras (50) avançando até as barras (6), onde são pressionados, retendo as abraçadeiras às tais barras (6). Isso possibilita a substituição do funil inferior (7) quando de sua troca por outro de bocal mais estreito ou mais largo, de acordo com a dosagem ou tipo de produto a ser empacotado.  The present gate doser (1) further comprises a pair of vertical bars (6) along which clamps (50) slide which are connected to the cover (5). The clamps (50) are locked to the bars (6) by any known means, such as screws (51), which pass through the clamps (50) and advance to the bars (6), where they are pressed, retaining the clamps to such bars ( 6). This makes it possible to replace the lower funnel (7) when replacing it with a narrower or wider nozzle, according to the dosage or type of product to be packaged.
O ajuste da altura do elemento tubular (3) é feito para se variar a quantidade de produto a ser empacotado. Assim, ao se elevar o elemento tubular (3) diminui-se a distância entre as comportas primárias (21 ) e secundárias (31 ), reduzindo-se a quantidade de material entre elas, e consequentemente, reduzindo- se a quantidade de material a ser empacotado. De maneira inversa, ao se abaixar o elemento tubular (3) aumenta-se a distância entre as comportas (21 ) e (31 ), aumentando-se a quantidade de material entre elas, e consequentemente, aumenta- se a quantidade de material a ser empacotado.  The height adjustment of the tubular element (3) is made to vary the amount of product to be packaged. Thus, raising the tubular element (3) decreases the distance between the primary (21) and secondary (31) gates, reducing the amount of material between them, and consequently reducing the amount of material to be packaged. Conversely, lowering the tubular member (3) increases the distance between the gates (21) and (31), increasing the amount of material between them, and consequently increasing the amount of material to be packaged.
Para tanto o elemento tubular (3) é fixado a um suporte (11 ) que por sua vez é conectado a uma porca (15) parafusada a uma rosca sem fim vertical (12), de forma que, ao se girar a rosca (12) o suporte (11 ) é movido para cima ou para baixo, conforme o sentido de giro da rosca (12), elevando ou abaixando o suporte (11 ), que leva consigo o elemento tubular (3). For this purpose the tubular element (3) is fixed to a support (11) which in turn it is instead connected to a nut (15) screwed to a vertical endless thread (12), so that by turning the thread (12) the bracket (11) is moved up or down according to the direction of rotation. thread (12) by raising or lowering the bracket (11), which carries the tubular member (3).
5 O suporte (11 ) tem seu movimento horizontal limitado por duas barras 5 The support (11) has its horizontal movement limited by two bars
(13) paralelas e laterais à rosca (12), as quais são atravessadas pelo suporte (11 ), guiando seu movimento ascendente ou descendente através das colunas (C). (13) parallel and lateral to the thread (12), which are traversed by the support (11), guiding its upward or downward movement through the columns (C).
Conforme ilustrado nas figuras anexas, a rosca sem fim (12) é movida, preferencialmente, por um motor (14), que faz a rosca (12) girar em torno de seu í o eixo, movimentando a porca (15) verticalmente e, consequentemente, o suporte (11 ) para cima ou para baixo, conforme o sentido de rotação do eixo do motor (14).  As illustrated in the accompanying figures, the endless thread (12) is preferably driven by a motor (14) which causes the thread (12) to rotate about its axis by moving the nut (15) vertically and, consequently the support (11) up or down according to the direction of rotation of the motor shaft (14).
Assim, de acordo com o volume que se deseja empacotar, ajusta-se a altura do elemento tubular (3), movendo-se seu suporte (11 ) para cima ou para baixo, afastando ou aproximando as comportas secundárias (31 ) das comportas 15 primárias (21 ), oferecendo um espaço maior ou menor entre elas, para ser preenchido pelo produto.  Thus, according to the volume to be packaged, the height of the tubular element (3) is adjusted by moving its support (11) up or down, moving or closing the secondary gates (31) from the gates 15. (21), offering a larger or smaller space between them to be filled by the product.
