Description
A presente patente tem por objetivo proteger a tecnologia de um prefusor, que é uma das partes componentes de um equipamento para colagem utilizado na fabricação de móveis, portas e aberturas e de forma mais específica, na colagem de bordas. O prefusor de meio adesivo desse pedido de patente, possui características inovadoras, possuindo a porção superior aberta, a qual permite maior aproveitamento do meio adesivo: mesmo com intervalos longos do equipamento desligado, a embalagem de meio adesivo parcialmente utilizada não se estraga. Cabe aqui ressaltar que, nos prefusores convencionais, ao se desligar o equipamento, o adesivo não utilizado, que restar, perde-se devido à cura consequente do contato com a umidade, o que não ocorre no modelo objeto desse documento. Também devido ao seu design inovador, esse equipamento permite melhor aproveitamento térmico devido à sua reduzida área de contato com o meio adesivo (que é inserido no equipamento em sua própria embalagem), dessa forma economizando grandes quantidades de energia durante seus ciclos de funcionamento.The purpose of this patent is to protect the technology of a prefuser, which is one of the component parts of a gluing equipment used in the manufacture of furniture, doors and openings and, more specifically, in the gluing of edges. The adhesive medium prefuser of this patent application has innovative characteristics, having an open upper portion, which allows greater use of the adhesive medium: even with long intervals of the equipment turned off, the partially used adhesive medium packaging is not damaged. It should be noted here that, in conventional prefusers, when the equipment is turned off, the unused adhesive, which remains, is lost due to the consequent curing of contact with moisture, which does not occur in the model object of this document. Also due to its innovative design, this equipment allows for better thermal use due to its reduced contact area with the adhesive medium (which is inserted into the equipment in its own packaging), thus saving large amounts of energy during its operating cycles.
Esse tipo de equipamento (coleiro de bordas) é largamente utilizado na fabricação de móveis, portas e aberturas e de forma mais específica, na colagem das bordas em si. Nesse sentido, os sistemas de colagem de bordas que utilizam meios adesivos do tipo "Hot-Melt" Poliuretano Reativo (PUR) possuem sistemas de prefusão, que proporcionam a liquefação do meio adesivo (doravante chamado apenas ‘adesivo’ a fim de simplificar o texto) para posterior transferência, por inércia, ao sistema, também aquecido, de aplicação de adesivo, propriamente dito, à superfície que irá receber o adesivo para colagem. This type of equipment (edge gluer) is widely used in the manufacture of furniture, doors and openings and, more specifically, in the gluing of the edges themselves. In this sense, edge bonding systems that use "Hot-Melt" Reactive Polyurethane (PUR) type adhesives have prefusion systems, which provide for the liquefaction of the adhesive medium (hereinafter called just 'adhesive' in order to simplify the text ) for subsequent transfer, by inertia, to the system, also heated, for applying the adhesive itself to the surface that will receive the adhesive for bonding.
Já são conhecidos no mercado os prefusores convencionais (geralmente com funcionamento a pistão, dentre outras tecnologias eletromecânicas) construídos em liga metálica e com câmara fechada, parte componente do equipamento coleiro de bordas, verticalizado e dotado de conexão inferior para o conjunto do corpo e o aplicador de adesivo e ao sistema industrial do usuário.Conventional prefusers are already known in the market (generally with piston operation, among other electromechanical technologies) built in metallic alloy and with a closed chamber, component part of the edge glue equipment, verticalized and equipped with a lower connection for the body assembly and the adhesive applicator and the user's industrial system.
Nos prefusores convencionais existe um compartimento metálico alongado e fechado, chamado de câmara, no qual o meio adesivo é inserido por inteiro e recebe calor distribuído de forma uniforme em toda sua extensão, durante o processo de prefusão. Como esses equipamentos efetuam a prefusão em todo o adesivo presente na câmara e não evitam o contato do meio adesivo com a umidade, então, quando desligados, causam a cura do meio adesivo, sem possibilidade de reutilização da porção não utilizada. Sem contar que, devido a maior superfície de contato da câmara do equipamento com o meio adesivo, é necessário maior quantidade de energia elétrica para aquecer e manter o equipamento e toda sua câmara de prefusão na temperatura correta, além da grande quantia de material utilizada em sua construção. In conventional prefusers, there is an elongated and closed metallic compartment, called a chamber, in which the entire adhesive medium is inserted and receives heat evenly distributed throughout its length during the prefusion process. As these devices perfuse all the adhesive present in the chamber and do not prevent contact between the adhesive medium and moisture, when turned off, they cause the adhesive medium to cure, with no possibility of reusing the unused portion. Not to mention that, due to the greater contact surface of the equipment chamber with the adhesive medium, a greater amount of electrical energy is required to heat and keep the equipment and its entire prefusion chamber at the correct temperature, in addition to the large amount of material used in its construction.
A tecnologia aplicada ao processo de modificação de engenharia que resultou nesse documento de patente, proporciona um equipamento de dimensões bastante reduzidas em relação aos modelos convencionais, utilizando menos matéria prima em sua construção, permitindo o reuso do meio adesivo não utilizado que é aquecido em sua própria embalagem e fica protegido hermeticamente da umidade, gasta menos energia elétrica devido à pequena área que necessita de aquecimento e simplifica o processo de limpeza, quando necessário, por ser completamente aberto e pequeno, dentre outras características inovadoras.The technology applied to the engineering modification process that resulted in this patent document, provides equipment with very reduced dimensions in relation to conventional models, using less raw material in its construction, allowing the reuse of the unused adhesive medium that is heated in its own packaging and is hermetically protected from moisture, uses less electricity due to the small area that needs heating and simplifies the cleaning process, when necessary, as it is completely open and small, among other innovative features.
Patente do sistema de prefusão utilizado em coleiros de bordas que utiliza adesivos do tipo "Hot-Melt" Poliuretano Reativo (PUR), caracterizado por uma estrutura verticalizada que recebe a embalagem do meio adesivo e é acoplada perfeitamente de forma mecânica, sem a necessidade do uso de adesivos específicos ao corpo do coleiro. O corpo do equipamento coleiro de bordas, por sua vez, é acoplado no sistema de aplicação do meio adesivo.Patent on the prefusion system used in edge melters that uses adhesives of the "Hot-Melt" Reactive Polyurethane (PUR) type, characterized by a vertical structure that receives the packaging of the adhesive medium and is coupled perfectly mechanically, without the need for use of adhesives specific to the body of the melter. The body of the edge gluer equipment, in turn, is attached to the adhesive medium application system.
O processo de engenharia de construção do prefusor, objeto desse pedido de patente, utiliza tecnologias de usinagem negativa e eletroerosão, ambas de precisão, que garantem o perfeito fluxo por inércia do adesivo aquecido e liquefeito na temperatura exata para o corpo do coleiro até o aplicador. The prefuser construction engineering process, object of this patent application, uses negative machining and electroerosion technologies, both of precision, which guarantee the perfect flow by inertia of the heated and liquefied adhesive at the exact temperature for the body of the gluer to the applicator. .
A fixação do equipamento completo na linha de produção do usuário, ocorre através de conexão mecânica padronizada e pode possuir diferentes configurações, de acordo com as características da linha de produção, posicionando o equipamento para a esquerda, para a direita ou centralizado em relação à peça que irá receber o meio adesivo liquefeito para colagem.Fixing the complete equipment to the user's production line takes place through a standardized mechanical connection and can have different configurations, according to the characteristics of the production line, positioning the equipment to the left, to the right or centered in relation to the part. which will receive the liquefied adhesive medium for bonding.
Nos prefusores convencionais, todo adesivo presente na câmara é aquecido para que após liquefeito, seja transferido da câmara do prefusor para o corpo do coleiro e posteriormente, para o sistema aplicador. Essa transferência pode acontecer empurrada por sistemas de pistão, pressurização, dentre outras formas. Além do que, dada a construção dos prefusores convencionais para coleiros de bordas, sua câmara não é projetada com as características técnicas necessárias a fim de permitir que seja fechada hermeticamente, impedindo a entrada de umidade no sistema após seu desligamento. Dessa forma, em caso de desligamento do equipamento e posterior resfriamento, dada a liquefação total do meio adesivo presente na câmara em contato com a umidade, ocorre a cura do meio adesivo não utilizado, acarretando o seu descarte.In conventional prefusers, all adhesive present in the chamber is heated so that, after being liquefied, it is transferred from the prefuser chamber to the body of the melter and subsequently to the applicator system. This transfer can happen pushed by piston systems, pressurization, among other ways. In addition, given the construction of conventional prefusers for edge gluers, their chamber is not designed with the necessary technical characteristics in order to allow it to be hermetically closed, preventing moisture from entering the system after it is turned off. Thus, in case of equipment shutdown and subsequent cooling, given the total liquefaction of the adhesive medium present in the chamber in contact with humidity, the unused adhesive medium cures, leading to its disposal.
Outro problema encontrado no prefusor convencional é o alto consumo energético. Como a área da superfície aquecida estende-se por toda a câmara, faz-se necessário obviamente gasto muito maior de energia elétrica para aquecê-lo na temperatura correta e depois para mantê-lo aquecido, dado o processo de troca de calor que ocorre com o meio a todo o momento. Another problem found in the conventional prefuser is the high energy consumption. As the heated surface area extends over the entire chamber, it is obviously necessary to spend much more electrical energy to heat it to the correct temperature and then to keep it warm, given the heat exchange process that occurs with the middle at all times.
Tendo em vista esses problemas e no propósito de superá-los, ao mesmo tempo em que se busca trazer maior praticidade no uso do equipamento pelos usuários, fora desenvolvido o sistema de prefusão ‘opentop’ para adesivos do tipo "Hot-Melt" Poliuretano Reativo (PUR), objeto da presente patente, a qual consiste em um novo projeto para o prefusor do coleiro a fim de eliminar o problema da perda de matéria prima não utilizada (adesivo) o qual é aquecido na própria embalagem, bem como a economia de energia durante o seu uso. Além disso, o design inovador garante a auto-fixação da embalagem e sua vedação com a própria cola, garantindo proteção hermética ao meio adesivo não utilizado.Bearing in mind these problems and with the aim of overcoming them, while seeking to bring greater practicality in the use of the equipment by users, the 'opentop' prefusion system for "Hot-Melt" Reactive Polyurethane adhesives was developed (PUR), object of the present patent, which consists of a new project for the glue prefuser in order to eliminate the problem of the loss of unused raw material (adhesive) which is heated in the packaging itself, as well as the economy of energy during use. In addition, the innovative design guarantees the self-fixation of the package and its sealing with its own glue, guaranteeing hermetic protection to the unused adhesive medium.
Para tal, é importante ressaltar que a tecnologia inovadora e disruptiva dessa patente permite que o equipamento prefusor ‘opentop’ para adesivos do tipo “Hot-Melt” Poliuretano Reativo (PUR) tenha diferentes designs internos para liquefação do meio adesivo e transporte via inércia em ambiente hermeticamente protegido do adesivo liquefeito para o corpo do coleiro. Dependendo da aplicação do cliente podem ser utilizados nos equipamentos prefusores design em janela, conforme ilustrado pela , design em grelha doravante visto na , ou até mesmo designs diferentes, como barras, diedros, peneiras, dentre outros. Para fins desse documento de patente, para melhor visualização e descrição da invenção serão apresentados apenas dois modelos, em janela (3) e grelha (11), respectivamente.To this end, it is important to emphasize that the innovative and disruptive technology of this patent allows the 'opentop' prefuser equipment for “Hot-Melt” Reactive Polyurethane (PUR) type adhesives to have different internal designs for liquefaction of the adhesive medium and transport via inertia in hermetically protected environment from the liquefied adhesive to the paste body. Depending on the customer's application, window design spray guns can be used, as illustrated by the , grid design henceforth seen on , or even different designs, such as bars, dihedrals, sieves, among others. For the purposes of this patent document, for a better visualization and description of the invention, only two models will be presented, in window (3) and grid (11), respectively.
O novo design supracitado é inovador se levado em consideração o modelo convencional, sendo construído com processos de usinagem negativa de precisão e acabamento interno realizado com eletroerosão também de precisão, o que confere perfeito encaixe às embalagens de adesivo presentes no mercado, garantindo sua proteção hermética durante o uso. The aforementioned new design is innovative if taken into account the conventional model, being built with precision negative machining processes and internal finishing carried out with precision electro-erosion, which also provides a perfect fit to the adhesive packaging on the market, guaranteeing its hermetic protection during use.
Nesse sentido, conforme ilustrado pelas figuras acima mencionadas, o sistema de prefusão ‘opentop’ possui a parte superior completamente aberta, ficando a superfície de contato para aquecimento do meio adesivo reduzida ao um pequeno percentual na base da embalagem do adesivo, o que é exemplificado nas figuras (2), (5), (10) e (13). Dessa forma, ao se aquecer o meio adesivo em pequenas proporções, a própria inércia gerada pelo peso do adesivo liquefeito em si, após o seu deslocamento para o corpo do coleiro através de (3), (6), (11) e (15) faz com que, quando necessário, o próprio adesivo ainda não liquefeito deslize internamente pela embalagem, também por inércia e se aproxime lentamente da área onde recebe calor proporcionalmente até o ponto de se tornar também liquefeito e se encaminhar ao corpo do coleiro e finalmente, chegar ao aplicador.In that In this sense, as illustrated by the aforementioned figures, the 'opentop' prefusion system has the upper part completely open, with the contact surface for heating the adhesive medium reduced to a small percentage at the base of the adhesive package, which is exemplified in the figures (2), (5), (10) and (13). In this way, when heating the adhesive medium in small proportions, the inertia itself generated by the weight of the liquefied adhesive itself, after its displacement to the body of the melter through (3), (6), (11) and (15) ) causes, when necessary, the still not liquefied adhesive itself to slide internally through the packaging, also by inertia and slowly approach the area where it receives heat proportionally until the point of also becoming liquefied and forwarded to the body of the gluer and finally, reach the applicator.
O leiaute inédito aplicado ao prefusor ‘opentop’ onde o adesivo liquefeito por aquecimento na própria embalagem se desloca por movimento inercial, soluciona os inconvenientes tratados anteriormente, uma vez que impede tanto o desperdício do meio adesivo não utilizado, quanto o excessivo consumo energético gasto em seu aquecimento e posterior manutenção da temperatura ideal de trabalho, considerando a perda térmica para o meio. The unprecedented layout applied to the 'opentop' prefuser, where the adhesive liquefied by heating in the package itself moves by inertial movement, solves the inconveniences dealt with previously, since it prevents both the waste of unused adhesive medium and the excessive energy consumption spent on its heating and subsequent maintenance of the ideal working temperature, considering the heat loss to the environment.
Além do que, seu design faz como que o adesivo fique hermeticamente protegido no prefusor após seu resfriamento pois a fixação da embalagem e sua vedação é realizada pelo próprio meio adesivo, evitando o contato com umidade o que causaria a cura do meio adesivo não utilizado.In addition, its design means that the adhesive is hermetically protected in the prefuser after cooling, as the package is fixed and sealed by the adhesive itself, avoiding contact with moisture, which would cause the unused adhesive to cure.
Quanto à formação dos resíduos de adesivo no prefusor ‘opentop’, praticamente se elimina a necessidade da limpeza após determinadas horas de utilização do equipamento na linha de produção, como ocorre com o modelo do prefusor convencional com câmara. Mesmo quando alguma limpeza é necessária, devido à sua área reduzida e design completamente aberto, o processo de limpeza do prefusor ‘opentop’ torna-se muito simplificado. No modelo de prefusor convencional com câmara, de acordo com a quantia de horas de utilização, há um tipo específico de limpeza que precisa ser efetuado.As for the formation of adhesive residues in the 'opentop' prefuser, the need for cleaning after certain hours of use of the equipment in the production line is practically eliminated, as with the conventional prefuser model with chamber. Even when some cleaning is required, due to its small area and completely open design, the 'opentop' prefuser cleaning process becomes very simplified. In the conventional prefuser model with chamber, according to the number of hours of use, there is a specific type of cleaning that needs to be carried out.
Os procedimentos de manutenção preventiva no modelo de prefusor ‘opentop’ previstos de acordo com o manual do fabricante tornam-se muito mais simples, pois, uma vez que não há significativos resíduos de adesivo depositados no interior do equipamento, sua manutenção preventiva se torna muito mais rápida. Além disso, é reduzida a praticamente zero a possibilidade de um técnico danificar o prefusor ‘opentop’ com ferramentas de desmonte, uma vez que sua parte superior completamente exposta não oferece dificuldade ao acesso, bem como, o desacoplamento de suas partes, acopladas mecanicamente, praticamente não acumulam resíduos de adesivo na conexão com o corpo do coleiro. Preventive maintenance procedures in the 'opentop' prefuser model, provided in accordance with the manufacturer's manual, become much simpler, since, since there is no significant residue of adhesive deposited inside the equipment, its preventive maintenance becomes much easier. faster. In addition, the possibility of a technician damaging the 'opentop' prefuser with dismantling tools is reduced to practically zero, since its completely exposed upper part does not offer difficult access, as well as the decoupling of its parts, mechanically coupled, they practically do not accumulate adhesive residues in the connection with the glue body.

O equipamento objeto dessa patente é parte componente do equipamento coleiro de bordas coleiro de bordas que utiliza adesivos do tipo "Hot-Melt" Poliuretano Reativo (PUR) especificamente, não sendo compatível com outras tecnologias de colagem que utilizam outros tipos de meios adesivos. The equipment object of this patent is a component part of the edge gluer equipment that uses adhesives of the "Hot-Melt" Reactive Polyurethane (PUR) type specifically, not being compatible with other bonding technologies that use other types of adhesive means.
A presente patente se refere ao setor de máquinas para fabricação de móveis, portas e aberturas e, de forma mais específica, a modalidade de fabricação de equipamentos para colagem de bordas na fabricação de peças para móveis, portas e aberturas, destinadas ao uso em residências, escritórios, fábricas e edificações de diversos tipos, objetivando simplificar os sistemas de colagem de bordas, otimizando o consumo de rede energia elétrica e o espaço ocupado pelo equipamento. The present patent refers to the sector of machines for the manufacture of furniture, doors and openings and, more specifically, the method of manufacturing equipment for gluing edges in the manufacture of parts for furniture, doors and openings, intended for use in homes. , offices, factories and buildings of various types, with the aim of simplifying edge bonding systems, optimizing consumption of electrical energy and the space occupied by the equipment.
Nesse sentido, os sistemas de colagem de bordas que utilizam adesivos do tipo "Hot-Melt" Poliuretano Reativo (PUR) utilizam sistemas de prefusão, que proporcionam uma liquefação do meio adesivo para posterior transferência ao sistema aquecido de aplicação de adesivo, propriamente dito, à superfície que recebe a borda de acabamento das laterais da chapa.In this sense, edge bonding systems that use adhesives of the "Hot-Melt" Reactive Polyurethane (PUR) type use prefusion systems, which provide a liquefaction of the adhesive medium for later transfer to the heated system for applying the adhesive, itself, to the surface that receives the finishing edge of the sides of the plate.
Efetivamente, a presente invenção tem por objetivo a proteção da tecnologia e design do prefusor denominado ‘opentop’ do coleiro, que irá funcionar com melhor desempenho do que os usuais, devido ao fato de aquecer o adesivo na própria embalagem evitando o desperdício do meio adesivo não utilizado, ao mesmo tempo em que economiza energia. À medida que as peças de madeira passarem pelo aplicador do coleiro, o prefusor terá trazido o adesivo em sua embalagem à temperatura exata para aplicação, e este, por sua vez, liquefeito e aquecido, desce por inércia através da carcaça e segue até o aplicador do adesivo, onde é depositado em quantia exata na peça em local específico e o processo de produção segue seu curso. Effectively, the present invention aims to protect the technology and design of the so-called 'opentop' prefuser of the melter, which will work with better performance than the usual ones, due to the fact that the adhesive is heated in the packaging itself, avoiding the waste of the adhesive medium. unused while saving energy. As the pieces of wood pass through the glue applicator, the prefuser will have brought the adhesive in its packaging to the exact temperature for application, and this, in turn, liquefied and heated, descends by inertia through the carcass and goes to the applicator. of the adhesive, where it is deposited in an exact amount on the piece in a specific place and the production process follows its course.
