Description

"DISPOSITIVO DE TRANSFERENCIA DE BOLSAS PARA MAQUINAS ENVASADORAS AUTOMÁTICAS" "BAG TRANSFER DEVICE FOR AUTOMATIC PACKAGING MACHINES"

Sector técnico de la invención.Technical sector of the invention.

Tiene por objeto la presente invención un dispositivo de transferencia de bolsas para máquinas envasadoras automáticas, que en general es aplicable a máquinas envasadoras automáticas de productos líquidos, sólidos, granulados, triturados o pulverulentos.The present invention aims at a bag transfer device for automatic packaging machines, which in general is applicable to automatic packaging machines for liquid, solid, granulated, crushed or powdered products.

Antecedentes de la invención.Background of the invention.

Son conocidas numerosas realizaciones de máquinas envasadoras automáticas de productos que, en síntesis, comprenden medios de conformación de envases en forma de bolsa, cuales bolsas tienen un reducido espesor y un formato esencialmente cuadrangular, obtenidas partir de una lámina de material termosoldable, medios de llenado de bolsas o dosificador de producto y medios de cierre de bolsas conteniendo la dosis de producto. En general, los medios de conformación de bolsas, de llenado de bolsas y de cierre de bolsas, están dispuestos sobre un bastidor en alineación longitudinal y operan de modo sincronizado a través de un controlador de proceso.Numerous embodiments of automatic product packaging machines are known which, in synthesis, comprise means for forming bag-shaped containers, which bags have a reduced thickness and an essentially quadrangular format, obtained from a sheet of heat-sealable material, filling means of bags or product dispenser and bag closure means containing the product dose. In general, the means for forming bags, for filling bags and for closing bags, are arranged on a frame in longitudinal alignment and operate synchronously through a process controller.

El documento de patente EP-A-0376174 describe una máquina envasadora del tipo anteriormente explicado.EP-A-0376174 describes a packaging machine of the type explained above.

En las máquinas envasadoras lineales conocidas, las bolsas son trasladadas durante su recorrido por las suce- sivas fases mediante unos medios de transporte, por ejemplo, mediante una pluralidad de pinzas que describen una trayectoria de vaivén.In known linear packaging machines, the bags are moved during their journey through the successive phases by means of transport, for example, by a plurality of tweezers describing a swinging path.

El inventor de la presente invención es también autor de otra invención referente a máquinas envasadoras automáticas en las que el tren conformador y el tren envasador, comprendiendo este último, medios de apertura, medios de llenado, medios de cierre y medios transporte, están dispuestos entre sí perpendicularmente . Tal disposición de mutua perpendicularidad entre el tren conformador y el tren envasador permite aumentar la capacidad de envasado de máquinas envasadoras de productos líquidos y sólidos en las que los tiempos de llenado son importantes y/o la velocidad de transporte de las bolsas previamente a su cierre viene limitada por el contenido de la bolsa. El incremento de capacidad de envasado de éstas máquinas envasadoras se consigue por transferencia de las bolsas desde una línea de suministro definida por el tren conformador a dos o más líneas de envasado, provistas de respectivos dispositivos de llenado de bolsas y disposi- tivos de cierre de bolsas, consiguiéndose de éste modo multiplicar la capacidad de producción respecto de las realizaciones de máquinas envasadoras de estructura completamente longitudinal .The inventor of the present invention is also the author of another invention concerning automatic packaging machines in which the forming train and the packaging train, the latter comprising, opening means, filling means, closing means and transport means, are arranged between Yes perpendicularly. Such an arrangement of mutual perpendicularity between the forming train and the packaging train allows to increase the packaging capacity of liquid and solid product packaging machines in which the filling times are important and / or the transport speed of the bags prior to closing. It is limited by the contents of the bag. The increase in packaging capacity of these packaging machines is achieved by transferring the bags from a supply line defined by the forming train to two or more packaging lines, provided with respective bag filling devices and closure devices for bags, thus being able to multiply the production capacity with respect to the realizations of packaging machines with a completely longitudinal structure.

Sin embargo, los primeros ensayos han revelado que la maniobra de transferencia de las bolsas desde la línea de suministro de las mismas, hasta los medios de apertura, es muy importante que se produzca con gran precisión. En caso contrario, ocurren averías o interrupciones que afec- tan negativamente al rendimiento general de la máquina envasadora. Con la presente invención, el inventor da a conocer un dispositivo de transferencia de bolsas con prestaciones mejoradas para lograr una eficaz transferencia coplanaria y sincronizada de bolsas desde una línea de suministro de bolsas definida por un tren conformador a dos o más líneas de envasado dispuestas perpendiculármente respecto de la línea de suministro.However, the first tests have revealed that the maneuver of transferring the bags from their supply line, to the opening means, is very important to occur with great precision. Otherwise, breakdowns or interruptions occur that adversely affect the overall performance of the packaging machine. With the present invention, the inventor discloses a bag transfer device with improved performance to achieve an efficient coplanar and synchronized transfer of bags from a bag supply line defined by a forming train to two or more packaging lines arranged perpendicularly Regarding the supply line.

Cada uno de los mecanismos de transferencia 5 comprende un eje de transferencia 7 dispuesto verticalmente entre el eje longitudinal teórico 6 y la correspondiente línea de envasado 4. El eje de transferencia 7 está unido por su porción extrema inferior 8 a través de un adaptador 9 a unos mecanismos de traslación lineal y a unos mecanis- mos de giro que lo desplazan evolucionando del modo que se describirá. Tales mecanismos de traslación y de giro, ha efectos de lograr una mayor claridad de exposición, no han sido representados en las figuras de las hojas de dibujos; se entiende que dichos mecanismos pueden estar constituí- dos por cualquier tipo adecuado de accionadores, como por ejemplo accionadores mecánicos, neumáticos, hidráulicos, eléctricos, etc.Each of the transfer mechanisms 5 comprises a transfer axis 7 arranged vertically between the theoretical longitudinal axis 6 and the corresponding packaging line 4.
