Abstract

Dispositivo para llenar, cerrar y separar envases que contienen material a granel a partir de una estructura tubular de hoja termosoldable dispuesta concéntricamente a un conducto de alimentación del material a granel, comprendiendo medios para hacer bajar controladamente la estructura tubular por el exterior del conducto, dos barras soldadoras provistas de medios de corte soportadas por respectivas deslizaderas móviles sobre respectivas guías para deslizar en un plano ortogonal al eje del conducto, por debajo de su extremo, y medios para conferir a dichas deslizaderas un movimiento de vaivén en contraposición de fase, comprendiendo dichos medios dos árboles locos paralelos ortogonales a las guías y vinculados para girar juntos, soportando cada uno por lo menos una leva que tiene perfil simétrico con el de la leva soportada por el otro árbol, comprendiendo cada deslizadera por lo menos un seguidor de leva deslizable sobre la leva del árbol más próximo.

Description

Dispositivo para llenar, cerrar y separar envases que contienen material a granel.
La presente invención se refiere a un dispositivo para llenar, cerrar y separar envases que contienen material a granel.
Son conocidas máquinas que, a partir de una banda de material termosoldable adecuado para contener elementos, crean una estructura tubular enfilada en el exterior de un conducto a través del cual es alimentado material a granel, como por ejemplo café en granos.
La estructura tubular es sometida, en posiciones equidistantes, a una operación de soldadura y corte, gracias a la cual se separan de la estructura principal unos envases herméticamente cerrados que contienen cantidades dosificadas de material.
La presente invención se refiere de modo específico a los dispositivos de soldadura y corte de la estructura tubular.
Dichos dispositivos comprenden dos barras soldadoras opuestas, dispuestas por debajo del extremo inferior del conducto, las cuales son móviles entre dos posiciones respectivamente separadas y aproximadas y están dotadas de medios de corte que entran en función cuando las mismas se encuentran en la posición aproximada.
Se realiza el movimiento en contraposición de fase de dichas barras soldadoras, en la técnica conocida, por medio de sistemas de manivelas y palancas que mandan unos accionadores neumáticos o eléctricos.
Los dispositivos conocidos, además de una complicada construcción, presentan también un volumen elevado que limita su empleo a específicos modelos de máquinas llenadoras, con grave limitación de su versatilidad de empleo.
El objetivo de la presente invención es poner a disposición un dispositivo para el cierre, la soldadura y la separación de envases, extraídos de una estructura tubular, que sea de construcción simplificada y volumen contenido, y que pueda ser aplicado en una amplia gama de máquinas llenadoras como un componente modular apto para funcionar de modo autónomo.
El objetivo se consigue con un dispositivo que obtiene las características mencionadas en las reivindicaciones.
Los valores y las características funcionales y constructivas de la invención resultarán evidentes de la descripción detallada que sigue que, con la ayuda de los planos anexos, ilustra una forma preferida de realización dada a título de ejemplo no limitativo.

De la figura 1 a la figura 5 se observa un conducto fijo rígido 1 sobre el cual está enfilada una estructura tubular 2 de hoja de material alimentario termosoldable, la cual está retenida en posición y deslizada sobre el conducto 1 por un par de correas opuestas 3, 33 cerradas en anillo y accionadas en intermitencia por un motor de avance controlado y una transmisión adecuada.
Los medios de accionamiento de las correas 3, 33 están ilustrados en la figura 2 y comprenden un motor de avance controlado 100 que a través de un reenvío ortogonal 101, la transmisión de correa 102 y un par de engranajes 103 acciona un par de árboles cardánicos contrarrotativos 104 (uno solo es visible en la figura) cada uno acoplado a una de las dos poleas motrices sobre los cuales se arrolla una de las correas 3, 33.
Debajo del extremo inferior del conducto 1, está dispuesto un par de vástagos paralelos horizontales 4, 44 (figuras 4, 5) sobre los cuales deslizan unas deslizaderas 5, 55.
Los vástagos están cada uno sostenido por una ménsula central 6, 66 que se proyecta desde una armadura 700 sostenida por la pared lateral 7 del cuerpo del dispositivo.
Entre las paredes opuestas de la armadura 700 del dispositivo están sostenidos dos árboles locos 8 y 88, paralelos entre si, ortogonales respecto a los vástagos 5, 55 y coplanarios con los mismos.
En los extremos de cada árbol 8 y 88 están calados dos discos circulares 9, simétricos uno respecto al otro, cuyo cubo es excéntrico, los cuales presentan una leva 91 desmodrómica circular excéntrica respecto al eje del respectivo árbol 8, 88; en la leva desliza un seguidor de leva 92 solidario de la deslizadera 5, 55 próxima al respectivo árbol.
En el ejemplo de las figuras 4 y 5 el árbol 88 comprende una polea intermedia 81 que está acoplada por una transmisión de correo 82 con una polea 83 que tiene un diámetro doble del de la polea 81. La polea 83 está calada sobre un árbol 84 que presenta una manivela 85 cuyo extremo está acoplado a su vez al grupo cilindro pistón 86.
Este último impone al árbol 84 oscilaciones de 90º que se traducen en oscilaciones de 180º del árbol 88.
Los dos árboles 8 y 88 están acoplados para girar juntos por una transmisión de correa 87 que acopla dos poleas 89 caladas sobre el cubo de los discos 9 dispuestos en los extremos correspondientes de los árboles 8, 88.
Las dos deslizaderas 5, 55 soportan en el centro dos barras soldadoras 50 y 550 fijadas a la respectiva deslizadera por medios elásticos 51, 551.
Por lo menos una de las barras comprende una cuchilla de corte 52 que desliza dentro y fuera de una hendidura de la deslizadera 55 accionada por una leva 56 calada sobre el árbol 88. La forma de accionamiento de las figuras 6 a 9 difiere de la de las figuras 1 a 5 sólo por los medios de accionamiento de las deslizaderas 5, 55; en estas figuras los componentes idénticos a los de las figuras 1 a 5 están señalados con las mismas referencias numéricas.
El árbol 88 soporta también en este caso una polea intermedia 810 que está acoplada por una transmisión de correa 820 con una polea 830 calada sobre el árbol del motor de avance controlado 840, el cual es mandado para imponer al árbol 88 rotaciones de 180º.
Las figuras 10 a 13 ilustran una tercera forma de realización de la invención que difiere de las figuras 6 a 9 por el hecho de que las ménsulas 6, 66, los vástagos 4, 44 y los árboles 8, 88 no son solidarios de las paredes 7 de la máquina, si no de una armadura 700 móvil verticalmente.
La armadura 700 está suspendida de las paredes 7 de la máquina mediante dos bielas 701.
Los extremos superiores de las bielas 701 están articulados a la pared 7, mientras que los extremos inferiores están articulados excéntricamente a correspondientes discos 702 calados en los extremos de los árboles 8, 88 que sobresalen de la armadura 700.
Cuatro guías verticales 703 vinculan la armadura 700 para deslizar paralelamente a sí misma.
El funcionamiento de la invención es el siguiente.
A partir de la operación de soldadura y corte del último envase (figura 3), es accionado el grupo cilindro pistón 86, o bien el motor 840 que imponen al árbol 88 una rotación de 180º gracias a la cual las deslizaderas 5, 55 son arrastradas por las levas 91 y respectivos seguidores de leva 92 para alejarse una de la otra; al mismo tiempo es accionado el motor 100 que pone en movimiento las correas opuestas 3, las cuales arrastran hacia abajo un tramo de estructura tubular 2 correspondiente al siguiente envase.
A través de medios no ilustrados dado que son usuales, a través del conducto 1 se hace descender en el envase la cantidad deseada de material, y en este punto es de nuevo accionado el grupo cilindro pistón 86, o bien el motor 840 que imponen al árbol 88 una rotación de 180º gracias a la cual las deslizaderas se aproximan poniendo las barras de soldadura en contacto una con la otra para cerrar el envase y el extremo inferior de la estructura tubular.
La acción de los medios usuales de corte, no ilustrados, separa el envase acabado de llenar del extremo inferior cerrado de la estructura tubular, y el ciclo se repite.
El funcionamiento de la máquina en las formas de realización de las figuras 1 a 9 es discontinuo.
La forma de realización de las figuras 10 a 13 permite en cambio un funcionamiento continuo.
De hecho la rotación de los árboles 8, 88 por medio de los discos 702 y las bielas 701 arrastra la armadura 700 a moverse verticalmente en sincronía con el movimiento de las deslizaderas 5, 55 y respectivas barras soldadoras, las cuales pueden así efectuar la soldadura mientras la estructura tubular continua descendiendo mandada por las correas 3.
