Description
SISTEMA DE MONITORAMENTO DE SOPROBLOW MONITORING SYSTEM
Refere-se o presente pedido de Patente de Invenção a um sistema de monitoramento de sopro, constituído por um ou mais sensores(Ol) instalados em uma sopradora de machos e moldes de areia, esta máquina é utilizada para produção de machos de areia para o setor de fundição, os sensores ou o sensor enviam informações em tempo real a IHM ligada a máquina.This invention patent application refers to a blowing monitoring system, consisting of one or more sensors (Ol) installed in a sand blower and sand molds, this machine is used for the production of sand cores for the foundry sector, the sensors or the sensor send information in real time to the HMI connected to the machine.
O sensor(Ol) é um equipamento elétrico mecânico composto de uma membrana interna que vibra conforme a pressão exercida dentro do canhão da máquina essa vibração é monitorada via cabo a IHM informando em tempo real e mostrando o gráfico gerado por essa função.The sensor (Ol) is a mechanical electrical equipment composed of an internal membrane that vibrates according to the pressure exerted inside the machine's cannon. This vibration is monitored via the HMI cable, reporting in real time and showing the graph generated by this function.
O objetivo do sistema de monitoramento de sopro é o de monitorar os problemas que ocorrem no momento em que a máquina de molde para fundição através do seu mecanismo de produção de macho de areia executa a função de misturar a areia com as resinas através da pressão de ar dentro de um ferramental que ira gerar o molde desejado.The objective of the blow monitoring system is to monitor the problems that occur when the casting machine through its sand-making machine performs the function of mixing the sand with the resins through the pressure of air inside a tool that will generate the desired mold.
Para uma maior compreensão do sistema de monitoramento de sopro, é necessário explicar o funcionamento da sopradora de machos e moldes de areia, que são as máquinas para fundição e que utilizam o mesmo método para produzir matrizes de areia e que nas fundições receberão a matéria prima derretida dentro delas e posteriormente as peças são retiradas.For a better understanding of the blowing monitoring system, it is necessary to explain the operation of the blow molding machine and sand molds, which are foundry machines and which use the same method to produce sand dies and which at the foundries will receive the raw material melted inside them and later the pieces are removed.
A máquina sopradora de machos e moldes é composta de um depósito misturador onde a areia é depositada e misturada com duas resinas, essa mistura é liberada através de uma válvula borboleta para o canhão de sopro este esta interligado a um reservatório de ar e por meio de tubos e válvulas recebe o ar em alta pressão pressionando a mistura para dentro do ferramental acoplado abaixo do canhão de sopro onde está a cavidade da peça a ser produzida, a areia preenche o molde da peça e através de um catalizador injetado se solidifica podendo ser retirado do ferramental.The core and mold blowing machine is made up of a mixing tank where the sand is deposited and mixed with two resins, this mixture is released through a butterfly valve for the blowing gun, which is connected to an air reservoir and by means of tubes and valves receives the air at high pressure by pressing the mixture into the tooling attached below the blow gun where the cavity of the part to be produced is located, the sand fills the part mold and through an injected catalyst it solidifies and can be removed of the tooling.
Os problemas resultantes desse processo são vários pois não se temThe problems resulting from this process are several because there is no
Petição 870180152806, de 19/11/2018, pág. 9/13Petition 870180152806, of 11/19/2018, p. 9/13
2/3 um controle imediato do resultado do procedimento de sopro, eles podem ser falta de controle de pressão do ar injetado, fuga de areia, falhas mecânicas, fuga de ar ao prensar a areia, a prensagem do ferramental, problemas de vedação e outros.2/3 an immediate control of the result of the blowing procedure, they can be lack of control of the injected air pressure, sand leakage, mechanical failures, air leakage when pressing the sand, the pressing of the tooling, sealing problems and others .
Os procedimentos atuais para sanar os problemas gerados por esses tipo de sistema são manuais e através de regulagens constantes até sanar os problemas.The current procedures to solve the problems generated by these types of systems are manual and through constant adjustments until the problems are solved.
O sistema de monitoramento de sopro vem para solucionar todos os problemas relacionados e outros que possam acontecer em tempo real, monitorando através dos sensores(Ol) o funcionamento da máquina e criando o próprio mecanismo de correção enviando informações a IHM acoplada a máquina ou ainda para computadores, tablets e celulares, gerando gráficos e relatórios.The blowing monitoring system comes to solve all related and other problems that may happen in real time, monitoring the machine's functioning through the sensors (Ol) and creating the correction mechanism itself, sending information to the HMI attached to the machine or even to computers, tablets and cell phones, generating graphs and reports.
O sistema de monitoramento de sopro é previamente programado através de um softer próprio que consiste em um gráfico com tabela de cores apresentado na tela da IHM ou de computadores, tablets e celulares, esse gráfico indica os padrões corretos do funcionamento da pressão exercida pelo canhão no momento em que o ar é injetado com alta pressão na areia depositada fazendo a mistura.The breath monitoring system is previously programmed using a dedicated softer that consists of a graph with a color table displayed on the HMI screen or computers, tablets and cell phones. This graph indicates the correct patterns of operation of the pressure exerted by the cannon in the moment when the air is injected with high pressure in the deposited sand making the mixture.
Quando algo acontece de errado no momento do sopro o gráfico pré definido sofre alterações, apresenta alterações nas cores e mostra comparativamente o gráfico correto e o gráfico com erros indicando quais os problemas do processo.When something goes wrong at the moment of the blow, the predefined graph changes, shows changes in colors and shows comparatively the correct graph and the graph with errors indicating the problems of the process.
O gráfico gera também um diagnóstico de controle da despresurização do interior do ferramental informando que o mesmo pode ser aberto para a retirada da peça.The graph also generates a diagnosis of control of the pressurization inside the tooling informing that it can be opened to remove the part.
O sistema de monitoramento de sopro gera também um aviso sonoro alertando para o problema que esta ocorrendo e a correção a ser adotada.The breath monitoring system also generates an audible warning alerting to the problem that is occurring and the correction to be adopted.
O sistema de monitoramento de sopro informará ao operador da máquina quais as correções que deverão ser feitas para que o processo saiaThe blowing monitoring system will inform the machine operator what corrections must be made for the process to exit
