Abstract

Patente de Invenção: <B>"SISTEMAS E MéTODOS PARA DETERMINAR DINAMICAMENTE PRESSõES DE SISTEMA DE AR BASEADO EM DADOS DE TEMPO DE AQUISIçãO DE FOLHA EM TEMPO REAL"<D>. Um alimentador de folha alimenta folhas separadas de uma pilha para a cabeça de alimentação que é transladável na direção dos cilindros de passo de retirada. As folhas são separadas da pilha por arrepeladores e adquiridos por uma superfície de aquisição da cabeça de alimentação que está em comunicação com uma pressão de vácuo. Uma lâmina de ar é usada, em conjunto com uma superfície de corrugação, para separar quaisquer folhas secundariamente adquiridas da superfície de aquisição. O tempo para adquirir a folha é determinado a partir da abertura de uma válvula de vácuo em comunicação com a cabeça de alimentação para a aquisição da folha pela superfície de aquisição. O tempo para adquirir as folhas é dependente das características da folha. Um controlador ajusta a pressão para os arrepeladores, lâmina de ar e a pressão de vácuo para controlar o tempo de aquisição de folha baseado nos tempos de aquisição de folha de um número predeterminado de folhas previamente alimentadas com sucesso e um desvio padrão quando comparado a uma tabela de tempos de aquisição de folha predeterminados e desvios padrão para as características de folha particular.
