Description
CONJUNTO DE MOVIMENTAÇÃO DE ÊMBOLO PISTON DRIVING ASSEMBLY
Campo da Invenção Field of the Invention
[0001 ] A presente invenção refere-se a um conjunto de movimentação de êmbolo, particularmente desenvolvido para ser aplicado em equipamentos e máquinas para preparo de bebidas instantâneas. Mais preferencialmente, o conjunto de movimentação de êmbolo, de acordo com a presente invenção, é compreendido por aspectos técnicos, construtivos e funcionais especialmente projetados para garantir a locomoção precisa, segura e eficaz do êmbolo, assim como controlar e assegurar o posicionamento do referido êmbolo, de modo a propiciar o adequado esmagamento das cápsulas de bebidas durante o processo de preparo das mesmas. [0001] The present invention relates to a piston handling assembly, particularly developed for use in instant beverage preparation equipment and machines. More preferably, the piston movement assembly according to the present invention is comprised of technical, constructive and functional aspects specially designed to ensure accurate, safe and effective locomotion of the piston as well as controlling and ensuring the positioning of said piston. , so as to provide adequate crushing of the beverage capsules during the preparation process thereof.
Fundamentos da Invenção Background of the Invention
[0002] De acordo com o estado da técnica, são conhecidos diversos modelos de equipamentos e máquinas para o preparo de bebidas instantâneas, tais como bebidas quentes, frias, geladas, gaseificadas ou não. Como deve ser apreciado pelos técnicos no assunto, esses equipamentos e máquinas, promovem a mistura de água com um xarope ou concentrado de alguma bebida que, normalmente, encontra-se acondicionado em cápsulas individuais. According to the state of the art, various models of instant beverage preparation equipment and machines are known, such as hot, cold, frozen, carbonated or unsweetened beverages. As should be appreciated by those skilled in the art, such equipment and machines promote mixing water with a syrup or concentrate of some beverage that is normally packaged in individual capsules.
[0003] Essas cápsulas são, normalmente, submetidas a processamentos específicos que permitem o contato e a mistura desse xarope ou concentrado com a água, resultando na bebida escolhida e desejada pelo usuário. Dentre os modelos conhecidos, pode-se dizer que os mais comuns são aqueles cujas cápsulas são perfuradas para injeção da água no seu interior, e aqueles cujas cápsulas são esmagadas para serem rompidas de modo a propiciar o despejamento da bebida em um recipiente. Nota-se que praticamente todos os modelos possui um elemento móvel, tal como um êmbolo ou pistão, que se desloca no sentido das cápsulas para processá-las, seja para perfurar ou esmagar. [0003] These capsules are usually subjected to specific processing that allows contact and mixing of this syrup or concentrate with water, resulting in the beverage chosen and desired by the user. Among the known models, it can be said that the most common are those whose capsules are perforated for injection of water into them, and those whose capsules are crushed to be ruptured to allow the beverage to be poured into a container. It is noted that virtually all models have a movable element such as a piston or piston that moves towards the capsules to process them, either to puncture or crush.
[0004] Esse elemento móvel utilizado nos equipamentos e máquinas para preparo de bebidas instantâneas pode ser acionado por diversas formas, e com diferentes tecnologias, mas convencionalmente utilizam motores elétricos que
acionam uma espécie de fuso ou rosca sem fim, que carrega um êmbolo com construtividade desenvolvida para entrar em contato com as cápsulas e processá- las, sendo que em alguns casos existe a disposição de conjuntos de engrenagens, redutores, polias ou outros componentes auxiliares para promover o deslocamento do êmbolo ou pistão. This movable element used in instant beverage equipment and machinery can be actuated in a variety of ways and with different technologies, but conventionally use electric motors that drive a kind of endless spindle or thread that carries a plunger with a constructivity designed to contact the capsules and process them, and in some cases gear sets, reducers, pulleys or other auxiliary components are available to promote displacement of the piston or piston.
[0005] Teoricamente, a função desses conjuntos de movimentação de êmbolo é basicamente promover um deslocamento linear de avanço e recuo do êmbolo, aparentemente simples e sem grandes implicações ou dificuldades. Entretanto, na prática, verificou-se que os conjuntos conhecidos no estado da técnica destinados a promover essa movimentação dentro de um equipamento relativamente compacto, considerando que se trata de um aparelho eletroportátil, apresentavam alguns inconvenientes e restrições relacionados a limpeza, mas principalmente com questões relativas ao controle de deslocamento e posicionamento do êmbolo e, consequentemente, na qualidade das bebidas preparadas. Theoretically, the function of these piston movement assemblies is basically to promote a seemingly simple linear forward and reverse displacement of the piston without major implications or difficulties. However, in practice, it has been found that assemblies known in the state of the art to promote such movement within a relatively compact apparatus, considering that it is a portable appliance, had some drawbacks and restrictions related to cleanliness, but mainly with concerns concerning the displacement control and positioning of the piston and, consequently, on the quality of the prepared beverages.
[0006] Mais especificamente, nota-se que nos equipamentos e aparelhos mais antigos, e mais tradicionais, esse conjunto de movimentação de êmbolo é dotado de apenas um sensor de posicionamento, o qual identifica apenas o posicionamento inicial do êmbolo, ou seja, quando o mesmo está totalmente recuado. Porém, essa configuração acarreta sérios inconvenientes e riscos relativos ao deslocamento parcial do êmbolo que, em alguns casos, pode ser insuficiente para promover o adequado processamento ou esmagamento da cápsula, uma vez que o referido conjunto não consegue determinar quando o êmbolo atingiu seu deslocamento máximo e ideal. Logo, nestas ocasiões, constata-se que as bebidas preparadas podem apresentar uma composição fraca e sabor aguado, sendo bastante indesejável pelo usuário, uma vez que o xarope ou concentrado de bebida não foi despejado de forma apropriada. More specifically, it is noted that in older and more traditional equipment and apparatus such a piston movement assembly is provided with only one positioning sensor which identifies only the initial position of the piston, ie when the same is totally set back. However, this configuration entails serious drawbacks and risks related to partial displacement of the piston which in some cases may be insufficient to promote proper processing or crushing of the capsule as said assembly cannot determine when the piston has reached its maximum displacement. and ideal. Thus, on these occasions, it is found that the prepared beverages may have a poor composition and watery taste, being quite undesirable by the user since the syrup or beverage concentrate was not properly poured.
[0007] Outro inconveniente da disposição de sensores de posicionamento apenas no início de curso do êmbolo é quando ocorre uma falha durante o processamento e preparo da bebida, mais particularmente durante a movimentação do referido embolo. Por exemplo, caso ocorra uma queda no fornecimento de
energia elétrica, ou o motor elétrico quebre e precise ser trocado. Com a disposição apenas de sensor no início de curso, o conjunto de movimentação quando reiniciado não saberá de forma precisa o seu posicionamento ou onde havia parado e precisa reiniciar, o que acarreta em desajustes do equipamento. Another drawback of positioning sensor positioning only at the beginning of the piston stroke is when a failure occurs during processing and brewing, more particularly during movement of said piston. For example, should the supply of electrical power, or the electric motor breaks down and needs to be replaced. With only the sensor available at the start of travel, when the drive set is restarted, it will not know exactly where it has been positioned or where it has stopped and needs to restart, resulting in equipment malfunctions.
[0008] Em síntese, a disposição do sensor de posicionamento apenas no início de curso restringe e afeta a regulagem e funcionamento dos equipamentos e máquinas e, com isso, exige-se manutenções constantes o que acaba se tornando desagradável aos usuários. In summary, the placement of the positioning sensor only at the beginning of the stroke restricts and affects the regulation and operation of equipment and machines and thus requires constant maintenance which eventually becomes unpleasant to users.
[0009] No intuito de se obter soluções para esses inconvenientes, alguns fabricantes de equipamentos e máquinas de preparo de bebidas instantâneas passou a aplicar um segundo sensor de posicionamento disposto no final de curso e, com isso, tornou-se possível assegurar que o êmbolo ou pistão realize o deslocamento completo, identificando não apenas quando o mesmo encontra-se no inicio de curso, mas também quando atingiu o seu deslocamento total e final. In order to find solutions to these drawbacks, some manufacturers of instant beverage preparation equipment and machines have now applied a second end-of-stroke positioning sensor and thus it has been possible to ensure that the plunger or piston make the complete displacement, identifying not only when it is at the beginning of the course, but also when it has reached its full and final displacement.
[0010] Assim, tornou-se possível controlar com um pouco mais de precisão o deslocamento e o posicionamento do êmbolo dentro dos equipamentos e máquinas de preparo de bebidas, ou seja, com a disposição de dois sensores de posicionamento, um inicial e outro final de curso, foi possível obter um conjunto de movimentação de êmbolo mais preciso e seguro. Thus, it has become possible to control the displacement and positioning of the piston within the beverage preparation equipment and machines a little more precisely, ie with the arrangement of two positioning sensors, one initial and one final. of course, a more accurate and reliable piston drive
[001 1 ] Porém, apesar dessas propostas tecnológicas se mostrarem funcionais e solucionarem grande parte dos inconvenientes, verificou-se algumas limitações relativas a aplicabilidade dentro de aparelhos eletroportáteis, tais com os equipamentos e máquinas para preparo de bebidas instantâneas. [001 1] However, while these technological proposals prove functional and address most of the drawbacks, there have been some limitations regarding applicability within small appliances such as instant beverage preparation equipment and machines.
[0012] Mais especificamente, para conseguir aplicar um sensor de posicionamento de fim de curso, os fabricantes foram obrigados a dispô-lo no corpo do módulo de sustentação e esmagamento de cápsulas, particularmente próximo da extremidade onde efetivamente o êmbolo ou pistão atinge seu deslocamento máximo, e que representa a posição cuja cápsula foi integralmente esmagada e o xarope ou concentrado foi totalmente despejado.
[0013] No entanto, para permitir essa montagem, dispondo o sensor de posicionamento no fim de curso, é necessário posicionar peças e componentes próximos da região onde as cápsulas são acomodadas para serem esmagadas. Em alguns casos o sensor fica instalado em uma condição que permite a passagem de líquido, poeira e sujidades para dentro da carcaça do equipamento, tal como quando existem a disposições de rasgos e aberturas por onde o elemento de sensoriamento consegue contato para detectar a presença do êmbolo. Portanto, caso ocorra eventuais falhas no rompimento dos lacres das cápsulas, certamente o xarope ou concentrado de bebida pode vazar e entrar em contato com o sensor e os elementos que compõem esse sensor. More specifically, in order to be able to apply an end-of-range positioning sensor, manufacturers were required to place it on the body of the capsule crushing and holding module, particularly near the end where the piston or piston effectively reaches its displacement. maximum, and represents the position whose capsule was completely crushed and the syrup or concentrate was completely poured out. However, in order to allow this mounting, having the position sensor at the limit switch, it is necessary to position parts and components near the region where the capsules are accommodated to be crushed. In some cases the sensor is installed in a condition that allows liquid, dust and dirt to enter the equipment housing, such as when there are openings and tears where the sensing element can contact to detect the presence of the sensor. piston. Therefore, should any failures in the capsule seals break, the syrup or beverage concentrate may leak and come into contact with the sensor and the elements that make up the sensor.
[0014] Esse risco de ocasionar e acumular sujeira, especialmente na região onde o êmbolo de desloca é muito desagradável aos usuários e, ainda, bastante arriscado para o funcionamento do equipamento, uma vez que, como deve ser apreciado pelos técnicos no assunto, essa região onde o êmbolo se desloca apresenta uma configuração substancialmente estreita e de difícil acesso e, portanto, o usuário não consegue realizar uma limpeza adequada nesses locais, sem desmontar o equipamento. This risk of causing and accumulating dirt, especially in the region where the displacement piston is very unpleasant to users, and also quite risky for the operation of the equipment, as, as should be appreciated by those skilled in the art, this region where the plunger travels is substantially narrow and difficult to access and therefore the user cannot properly clean these areas without disassembling the equipment.
[0015] Em virtude dessas restrições de acesso e, consequentemente, de limpeza dessas regiões, verifica-se que ao longo do tempo e conforme a utilização do equipamento, essas sujeiras vão se acumulando, formando uma espécie de borra, que além de atrair bichos e insetos desagradáveis, pode comprometer o funcionamento mecânico dos componentes, inclusive propiciando a paralização do equipamento. Due to these restrictions of access and, consequently, of cleaning of these regions, it appears that over time and depending on the use of the equipment, these dirt accumulate, forming a kind of sludge, which in addition to attracting animals and unpleasant insects, can compromise the mechanical functioning of the components, including providing equipment shutdown.
[0016] Em síntese, de acordo com os ensinamentos revelados no estado da técnica, e com base nos equipamentos e máquinas disponíveis no mercado, verifica- se que o conjunto de movimentação do êmbolo atuais carecem de soluções práticas e eficazes que asseguram o adequado e controlado deslocamento e posicionamento do êmbolo e, simultaneamente, eliminam os problemas e riscos de formação e acúmulo de sujeiras em regiões de difícil acesso do equipamento de preparo de
bebidas, tais como a porção onde o êmbolo se movimenta para esmagar as cápsulas de bebidas. In summary, according to the teachings disclosed in the state of the art, and based on the equipment and machines available on the market, it appears that the current piston drive assembly lacks practical and effective solutions that ensure the proper and controlled displacement and positioning of the plunger while eliminating the problems and risks of dirt formation and buildup in hard to reach areas of beverages, such as the portion where the plunger moves to crush the beverage capsules.

Slot 17 are provided with positioning sensors 18, respectively, of stroke start 18a and stroke end 18b.
[0037] De acordo com uma concretização preferencial da presente invenção, o referido motor 12 aciona o dito fuso 13 através de um conjunto de engrenagens 19 responsáveis por transmitir o movimento de rotação do motor 12 ao mancai de
movimentação 20 que envolve o referido fuso 13. Dessa forma, conforme o motor elétrico 12 é acionado, ocorre a transferência de força para o conjunto de engrenagens 19 que, por sua vez, transmite a força ao dito mancai de movimentação que gira e, consequentemente, promove o deslocamento do fuso 13 arrastando a luva 15 com a dita aba 16 através do referido rasgo 17 previsto na capa estrutural 1 1 . In accordance with a preferred embodiment of the present invention, said motor 12 drives said spindle 13 through a set of gears 19 responsible for transmitting the rotational motion of motor 12 to the thrust bearing. drive 20 surrounding said spindle 13. Thus, as the electric motor 12 is driven, there is a transfer of force to the gear set 19 which, in turn, transmits the force to said drive bearing which rotates and consequently , promotes the displacement of the spindle 13 by dragging the sleeve 15 with said flap 16 through said slot 17 provided in the structural cover 11.
[0038] No momento em que a referida aba 16 entra em contato com o sensor de posicionamento de fim de curso 18b, detecta-se que o dito êmbolo 14 atingiu seu posicionamento máximo e, consequentemente, o esmagamento adequado da cápsula (C), tal como representado pela Figura 6. The moment said flap 16 contacts the limit position positioning sensor 18b, it is detected that said piston 14 has reached its maximum positioning and, consequently, the proper crushing of the capsule (C), as represented by Figure 6.
[0039] Como deve ser apreciado pelos técnicos no assunto, eventualmente, esse conjunto de engrenagens 19 possa ser suprimido, de modo que o próprio motor 12 esteja em contato direto com o referido mancai de movimentação 20 que proporcionará o deslocamento linear do referido fuso 13 com o dito êmbolo 14. Adicionalmente, esse referido motor 12 pode ser, preferencialmente, um motor elétrico, e mais preferencialmente ainda, um motor elétrico de passo, capaz de controlar efetivamente o deslocamento pulsado do referido fuso 13. As should be appreciated by those skilled in the art, such gear assembly 19 may eventually be suppressed so that motor 12 itself is in direct contact with said drive bearing 20 which will provide linear displacement of said spindle 13 with said piston 14. Additionally, said motor 12 may preferably be an electric motor, and most preferably an electric stepper motor, capable of effectively controlling the pulsed displacement of said spindle 13.
[0040] Conforme é possível constatar, em virtude da concretização proposta pela presente invenção, em especial para disposição e montagem da capa estrutural 1 1 sustentando os sensores de posicionamento 18, bem como a disposição da aba 16 na extremidade do dito fuso 13, permite-se solucionar diversos inconvenientes identificados no estado da técnica, particularmente, aqueles relacionados aos riscos de acumulo de sujeiras e formação de borras. As can be seen from the embodiment proposed by the present invention, in particular for arranging and mounting the structural cover 11 supporting the positioning sensors 18, as well as the arrangement of the tab 16 at the end of said spindle 13, allows A number of drawbacks identified in the prior art are identified, particularly those related to the risk of dirt accumulation and sludge formation.
