"MAQUINA ENVASADORA AUTOM TICA" "AUTOM TICA PACKING MACHINE"
Sector técnico de la invención.Technical sector of the invention.
Tiene por objeto la invención una máquina envasadora automática que, en general, es aplicable al envasado de productos líquidos, sólidos granulados, triturados o pulverulentos, tales como jugos de frutas, bebidas refrescantes, medicamentos, condimentos condensados, y otros semejantes .The object of the invention is an automatic packaging machine which, in general, is applicable to the packaging of liquid, granulated, crushed or powdered solids, such as fruit juices, soft drinks, medicaments, condensed condiments, and the like.
Antecedentes de la invención.Background of the invention.
Son conocidas numerosas realizaciones de máquinas envasadoras automáticas en las que los productos (alimentos, bebidas, medicamentos, etc.) son envasados en bolsas de material termoplástico de relativamente reducido espesor y formato esencialmente cuadrangular . En general, las realizaciones conocidas de máquinas envasadoras comprenden un bastidor sobre el que hay dispuesto un tren conformador y un tren envasador dispuestos en sucesión longitudinal; y estos trenes, a su vez comprenden, una pluralidad de medios que a su vez comprenden una pluralidad de dispositivos formados por una pluralidad de mecanismos que operan en continuo de forma sincronizada y que realizan la totalidad de operaciones relativas a la conformación del enva- se y al envasado del producto. Usualmente los medios que comprende el tren envasador son: medios de apertura del envase, medios de llenado, medios de cierre y medios para la recogida de bolsas conteniendo el producto envasado.Numerous embodiments of automatic packaging machines are known in which the products (food, beverages, medicines, etc.) are packed in thermoplastic bags of relatively reduced thickness and essentially quadrangular format. In general, known embodiments of packaging machines comprise a frame on which a forming train and a packaging train arranged in longitudinal succession are arranged; and these trains, in turn, comprise a plurality of means which in turn comprise a plurality of devices formed by a plurality of mechanisms that operate continuously in synchronized form and that perform all the operations related to the packaging conformation. and product packaging. Usually the means comprising the packaging train are: means for opening the package, filling means, closing means and means for collecting bags containing the packaged product.
El documento de patente EP-A-0376174 describe una máquina envasadora del tipo anteriormente explicado. Las máquinas envasadoras como las antes descritas trabajan de un modo en el que se distinguen las siguientes fases operativas : una primera fase en la que es conformada la bolsa y que comprende aquellas operaciones destinadas al suministro continuo de bolsas a los medios de apertura; una segunda fase en la que se procede al llenado de la bolsa; una tercera fase en la que se procede al cierre de la bolsa conteniendo el producto a envasar; y, una cuarta fase en la que se procede a la recogida de la bolsa para su disposición en el interior de cajas o receptáculos de embalaje similares para su transporte, almacenamiento y distribución a los puntos de venta. En general, las máquinas envasadoras están estructuradas de modo que una, dos ó más bolsas participan simultáneamente de las fases de envasado antes descritas, siendo el número de bolsas que evolucionan simultáneamente función, entre otros factores, de la naturaleza del producto a envasar, de las dimensiones de las bolsas, etc.EP-A-0376174 describes a packaging machine of the type explained above. Packaging machines such as those described above work in a way that distinguishes the following operational phases: a first phase in which the bag is formed and comprising those operations intended for the continuous supply of bags to the opening means; a second phase in which the bag is filled; a third phase in which the bag is closed containing the product to be packaged; and, a fourth phase in which the bag is collected for disposal inside similar boxes or packaging receptacles for transport, storage and distribution to the points of sale. In general, the packaging machines are structured so that one, two or more bags simultaneously participate in the packaging phases described above, the number of bags that evolve simultaneously depending on, among other factors, the nature of the product to be packaged, of the dimensions of the bags, etc.
En la totalidad de fases antes descritas, el tren conformador de bolsas, los medios de apertura, los medios de llenado y los medios de cierre de bolsas conteniendo el producto envasado permanecen estáticos, siendo la bolsa trasladada durante su recorrido por las sucesivas fases mediante los medios de transporte. En las condiciones de trabajo descritas, la bolsa, después de haber sido conformada es trasladada hasta los medios de apertura, donde queda a la espera de que la bolsa precedente sea llenada, por el dispositivo de llenado, con el producto a envasar, produciéndose en consecuencia un tiempo de espera que será función del volumen y propiedades físicas del producto a envasar. Este tiempo de espera entre fases consecutivas de llenado es un factor determinante en cuanto a la capacidad de envasado (unidades/minuto) de las máquinas. A título orientativo se cita que una máquina de tipo medio tiene una capacidad de envasado del orden de 100 bolsas/minuto.In all the phases described above, the bag forming train, the opening means, the filling means and the bag closing means containing the packaged product remain static, the bag being moved during its journey through the successive phases by means of the transport. Under the described working conditions, the bag, after being shaped, is transferred to the opening means, where it is waiting for the previous bag to be filled, by the filling device, with the product to be packaged, being produced in consequence a waiting time that will be a function of the volume and physical properties of the product to package. This waiting time between consecutive filling phases is a determining factor in terms of the packaging capacity (units / minute) of the machines. For guidance purposes, it is mentioned that a medium type machine has a packaging capacity of the order of 100 bags / minute.
La capacidad de envasado de las máquinas envasadoras antes descritas está además, directamente relacionada con la velocidad de desplazamiento de las bolsas, y ésta velócidad de desplazamiento debe ser reducida en una medida muy importante cuando el producto a envasar es un producto líquido de baja densidad, como así ocurre por ejemplo en el envasado de bebidas refrescantes. En efecto, una vez llenada la bolsa con la dosis de líquido, el paso de la bolsa desde los medios de llenado a los medios de cierre produce desplazamientos inerciales del líquido contenido en la bolsa aún abierta. Si la velocidad de desplazamiento es elevada se genera un pequeño oleaje en el líquido de modo que puede mojar los bordes superiores de la bolsa donde están las superficies a soldar por el dispositivo de cierre, lo cual dificulta cuando no imposibilita el sellado o cierre de la bolsa que tiene lugar en la fase siguiente . Para evitar este inconveniente se hace indispensable trabajar a velocidades de desplazamiento bajas, lo cual afecta muy importantemente a la velocidad de envasado.The packaging capacity of the packaging machines described above is also directly related to the speed of movement of the bags, and this speed of movement must be reduced to a very important extent when the product to be packaged is a low density liquid product, as is the case, for example, in the packaging of soft drinks. Indeed, once the bag is filled with the liquid dose, the passage of the bag from the filling means to the closing means produces inertial displacements of the liquid contained in the bag still open. If the speed of travel is high, a small swell is generated in the liquid so that it can wet the upper edges of the bag where the surfaces to be welded by the closing device are, which makes it difficult when the sealing or closing of the bag that takes place in the next phase. To avoid this inconvenience, it is essential to work at low travel speeds, which very importantly affects the packaging speed.

Los medios de recogida 6 comprenden, para cada una de las líneas de envasado 18, una respectiva rampa o cinta de salida 21 sobre la que deslizan las bolsas 16 cerradas conteniendo el producto envasado, cuales bolsas 16 son recibidas, por ejemplo, por un dispositivo de embalaje no representado .The collection means 6 comprise, for each of the packaging lines 18, a respective exit ramp or tape 21 on which the closed bags 16 containing the packaged product slide, which bags 16 are received, for example, by a device Packaging not shown.
Los medios de transporte 7 de bolsas 16 comprenden, en la línea de suministro 15, en la que las bolsas 16 es- tan unidas lateralmente mediante soldadura aplicada previamente a la operación de corte, unos rodillos de arrastre 22, y en cada una de las dos líneas de envasado 18, una pluralidad de pinzas 23 que ejecutando un movimiento de vaivén transportan las bolsas 16 desde el dis- positivo de transferencia 3 a las dos rampas o cintas de salida 21.The transport means 7 of bags 16 comprise, in the supply line 15, in which the bags 16 are joined laterally by welding previously applied to the cutting operation, drag rollers 22, and in each of the two packaging lines 18, a plurality of tweezers 23 which, in a reciprocating motion, carry the bags 16 from the transfer device 3 to the two exit ramps or belts 21.
La máquina envasadora automática según la invención antes descrita aporta una innovadora solución a los pro- blemas derivados de la baja capacidad de producción de aquellas realizaciones conocidas de máquinas envasadoras en las que un tren conformador de bolsas y un tren envasador, comprendiendo este último, medios de apertura, medios de llenado, y medios de cierre, están dispuestos en alineación longitudinal . El hecho de que en la máquina según la invención la única línea de suministro 15 de bolsas 16 enlace por medio del dispositivo de transferencia 3 con dos líneas de envasado 18 paralelas entre sí y dispuestas perpendicularmente respecto de dicha la línea de suministro 15, permite, como antes se ha explicado, en igualdad de condiciones de envasado referidas a volumen de bolsa 16 y producto a envasar, duplicar la capacidad de producción respecto de las realizaciones anteriormente conocidas de máquinas envasadoras . The automatic packaging machine according to the invention described above provides an innovative solution to the problems derived from the low production capacity of those known embodiments of packaging machines in which a bag forming train and a packaging train, the latter comprising, opening means, filling means, and closing means, are arranged in longitudinal alignment. The fact that, in the machine according to the invention, the only supply line 15 of bags 16 is connected by means of the transfer device 3 with two packaging lines 18 parallel to each other and arranged perpendicularly with respect to said supply line 15, allows, as explained above, on equal terms of packaging referred to bag volume 16 and product to be packaged, double the production capacity with respect to the previously known embodiments of packaging machines.
