Currently there are a wide variety of automatic machines on the market, packers of packages of a substantially rectangular geometry, where the trajectory of said packages, and therefore the structure of the machine, can have a rectilinear shape, a more curved shape or less elongated, or a circular shape.
El documento ES2123369B1 describe una máquina automática de carrusel circular diseñada para confeccionar bolsas paquete, de formato rectangular, que sigue un proceso de deposición del paquete, llenado, vibrado, cierre y soldeo de la abertura, corte y expulsión del paquete, caracterizado básicamente por comprender una estructura cilindrica, que recibe el movimiento circular sincronizado a través de un único eje, comprendiendo una pista de deslizamiento dispuesta convenientemente al vibrado y expulsión del paquete. Document ES2123369B1 describes an automatic circular carousel machine designed to make package bags, of rectangular format, which follows a process of deposition of the package, filling, vibrating, closing and welding the opening, cutting and expulsion of the package, basically characterized by comprising a cylindrical structure, which receives the synchronized circular movement through a single axis, comprising a sliding track conveniently arranged to vibrate and eject the package.
Esta máquina dispone de una pluralidad de cubiletes o vasos con forma de conducto rectangular recto, sin bases, de paredes rígidas, dispuestas en forma de matriz circular respecto del eje del que rota la máquina, de modo que dichos vasos o cubiletes van pasando por diferentes estaciones, como de llenado, vibración, plegado de la abertura de la bolsa, soldado de dicha abertura y expulsión de dicha bolsa, cada vez que el carrusel gira una posición. La pista de deslizamiento sobre la que se apoyan el fondo de las bosas durante cada uno de los procesos del carrusel es regulable en altura a través de una rueda o volante de fácil acceso. This machine has a plurality of goblets or glasses in the shape of a straight rectangular duct, without bases, with rigid walls, arranged in a circular matrix with respect to the axis of which the machine rotates, so that said glasses or goblets go through different stations, such as filling, vibrating, folding the opening of the bag, welding said opening and ejection of said bag, each time the carousel rotate one position. The sliding track on which the bottom of the bags rest during each of the carousel processes is adjustable in height through an easily accessible wheel or steering wheel.
Esta máquina descrita en el documento ES2123369B1 presenta unos problemas que son resueltos en la máquina descrita en el documento ES1105556U, el cual describe una máquina carrusel, con el objetivo de confeccionar bolsas paquete de una forma más eficiente. This machine described in document ES2123369B1 presents some problems that are solved in the machine described in document ES1105556U, which describes a carousel machine, with the aim of making package bags in a more efficient way.
De esta forma, el documento ES2123369B1 describe un carrusel que comprende un motor reductor para transmitir un movimiento de giro a la máquina con respecto a un eje vertical central. Dicho motor reductor permite que las bolsas paquete a confeccionar se desplazan por un perímetro circunferencial de dicha máquina de tipo carrusel haciendo programadas paradas para cada una de las bolsas paquete en cada estación de confeccionado. In this way, document ES2123369B1 describes a carousel comprising a gear motor to transmit a rotational movement to the machine with respect to a central vertical axis. Said reducer motor allows the package bags to be made to move around a circumferential perimeter of said carousel type machine, making programmed stops for each of the package bags at each manufacturing station.
Por otro lado, la máquina descrita en ES1105556U comprende un mecanismo motriz cruz de malta que evita que el motor tenga que realizar dichas paradas programadas. De este modo, la distribución angular de todos los ranurados de dicha cruz de malta está de acuerdo al tiempo de estancia de los cubiletes en las estaciones de la máquina, y más concretamente al tiempo de estancia en la estación que más tiempo requiera para llevar a cabo su labor. Es por ello que los tiempos de estancia son iguales en todas las estaciones de la dicha máquina descrita en ES1105556U. On the other hand, the machine described in ES1105556U comprises a Maltese cross drive mechanism that prevents the engine from having to carry out said programmed stops. In this way, the angular distribution of all the grooves of said malt cross is in accordance with the time of stay of the cups in the stations of the machine, and more specifically to the time of stay in the station that requires the longest to carry out. carry out your work. That is why the residence times are the same in all the stations of the said machine described in ES1105556U.
Sin embargo, esta configuración de cruz de malta comprende unos problemas respecto a la velocidad de funcionamiento, el ruido generado en el mecanismo, desgaste, así como un elevado coste requerido para la configuración de la cruz de malta en relación con los procesos realizados en la máquina. However, this malt cross configuration involves problems with regard to operating speed, noise generated in the mechanism, wear, as well as a high cost required for the malt cross configuration in relation to the processes carried out in the machine.
En lo referente al cerrado de las bolsas, en el documento ES2123369B1 no se describe el método utilizado para llevar a cabo el soldado y corte; mientras que en el documento ES1105556U se describe un dispositivo de cierre y corte de las bolsas paquete que comprende una pieza soporte que sustenta y guía dos elementos soporte con dos extremos, comprendiendo dos elementos de soldadura, una cuchilla de corte y un ranurado para la introducción de dicha cuchilla. Para la retirada del sobrante, dicha máquina, descrita en ES1105556U, comprende un dispositivo conectado a un elemento soporte, que sujeta la embocadura por encima de la línea de corte, para su retirada cuando es cortada. El problema de dicho dispositivo es que libera dicho sobrante en la propia máquina, pudiendo generar atascos indeseados que afecten al funcionamiento de la máquina. Regarding the closing of the bags, document ES2123369B1 does not describe the method used to carry out the welding and cutting; While document ES1105556U describes a device for closing and cutting package bags that comprises a support piece that supports and guides two support elements with two ends, comprising two welding elements, a cutting blade and a groove for the introduction of said blade. For the removal of the excess, said machine, described in ES1105556U, comprises a device connected to a support element, which holds the mouthpiece above the cutting line, for its removal when it is cut. The problem with said device is that it releases said excess in the machine itself, being able to generate unwanted jams that affect the operation of the machine.
En lo referente al sistema que hace vibrar las bolsas para facilitar y mejorar la compactación del producto a envasar, ninguno de los documentos, ES2123369B1 o ES1105556U, describe el procedimiento o mecanismo utilizado más allá de su vinculación con otras estaciones de la propia máquina, o de características que éste tiene, como activarse solo cuando tiene un paquete sobre él, o que actúa debido al efecto de un dispositivo de aire a presión. Regarding the system that makes the bags vibrate to facilitate and improve the compaction of the product to be packaged, none of the documents, ES2123369B1 or ES1105556U, describes the procedure or mechanism used beyond its connection with other stations of the machine itself, or of characteristics that it has, such as activating only when it has a package on it, or that it acts due to the effect of a pressurized air device.
DESCRIPCIÓN DE LA INVENCIÓN DESCRIPTION OF THE INVENTION
Para solucionar los problemas mencionados, la presente invención describe una máquina carrusel que comprende un mejorado sistema de giro de la parte móvil de dicho carrusel, un nuevo sistema de retirada del material sobrante de la bolsa que evita atascos indeseados, y un nuevo mecanismo de vibrado para mejorar el llenado y reparto del material en las bolsas paquete. To solve the problems mentioned, the present invention describes a carousel machine that comprises an improved system for turning the moving part of said carousel, a new system for removing excess material from the bag that avoids unwanted jams, and a new vibrating mechanism. to improve the filling and distribution of the material in the package bags.
De esta forma, la invención consiste en una maquina carrusel para confeccionar bolsas paquete, que comprende un proceso de deposición del paquete, vibrado, plegado, cierre, soldeo, y expulsión del paquete. Thus, the invention consists of a carousel machine for making package bags, which comprises a process of deposition of the package, vibrating, folding, closing, welding, and expulsion of the package.
Para realizar dicho proceso, o serie de etapas, dicha máquina carrusel comprende un disco móvil circular configurado para rotar sobre sí mismo, es decir, respecto del eje que define la forma circular de dicho disco móvil, y que comprende una pluralidad de cubiletes dispuestos en un perímetro exterior de dicho disco; el carrusel también comprende una estructura fija, respecto de la cual rota el disco móvil. To carry out said process, or series of stages, said carousel machine comprises a circular mobile disk configured to rotate on itself, that is, with respect to the axis that defines the circular shape of said mobile disk, and comprising a plurality of cups arranged in an outer perimeter of said disc; the carousel also comprises a fixed structure, with respect to which the movable disk rotates.
De esta forma, dicha máquina carrusel comprende un mecanismo engranado que a su vez comprende una corona con un dentado interior, fijada rígida y concéntricamente dicha corona al disco móvil circular, pudiendo formar parte del propio disco, y un piñón motriz montado en la estructura fija, engranado por el interior a la corona, y dispuesto de forma excéntrica a dicha corona. In this way, said carousel machine comprises a geared mechanism that in turn comprises a crown with internal toothing, rigidly and concentrically fixed said crown to the circular moving disk, being able to form part of the disk itself, and a pinion motor mounted on the fixed structure, internally meshed with the crown, and arranged eccentrically to said crown.
Este piñón motriz es accionable por un motor ensamblado en la estructura fija, de modo que, al accionar el piñón motriz se produce movimiento circular sincronizado del disco móvil respecto de la estructura fija, entre las diferentes etapas del proceso de la máquina carrusel. This drive pinion can be driven by a motor assembled on the fixed structure, so that, when the drive pinion is driven, there is synchronized circular movement of the mobile disk with respect to the fixed structure, between the different stages of the carousel machine process.
Es decir, que el motor acciona el piñón motriz y éste hace girar la corona y por lo tanto el disco móvil, desplazando los cubiletes entre las diferentes estaciones de la máquina carrusel. In other words, the motor drives the drive pinion and it rotates the crown and therefore the mobile disk, moving the cups between the different stations of the carousel machine.
En una realización, el mecanismo engranado comprende dos piñones guía montados en la estructura fija, engranados a la corona por el interior de ésta, y dispuestos de forma excéntrica a dicha corona; donde dichos dos piñones guía están configurados para limitar el movimiento de la corona únicamente a la rotación del disco móvil respecto de si mismo.

En caso de disponer de un solo piñón motriz y no tener piñones guía, el disco móvil podría desplazarse en cualquier dirección, además de girar sobre sí mismo, lo que supondría un problema para el funcionamiento de la máquina carrusel. In the case of having only one drive pinion and no guide pinions, the movable disk could move in any direction, in addition to turning on itself, which would be a problem for the operation of the carousel machine.
En una realización preferente, los piñones son cilindricos, estando en ese caso los dos piñones guía y el piñón motriz están orientados en una misma dirección, pero en realizaciones no preferentes, los piñones pueden tener una forma cónica. In a preferred embodiment, the pinions are cylindrical, in which case the two guide pinions and the drive pinion are oriented in the same direction, but in non-preferred embodiments, the pinions may have a conical shape.
En otras realizaciones que no comprenden dos piñones guía engranados con la corona, la máquina carrusel puede comprender otros medios para evitar el descentramiento del disco móvil, como estar ajustado a una cavidad cilindrica de la estructura fija, o comprender piñones guía por el exterior de la corona. In other embodiments that do not comprise two guide pinions meshed with the crown, the carousel machine can comprise other means to avoid the offset of the movable disk, such as being fitted to a cylindrical cavity of the fixed structure, or comprising guide pinions on the outside of the Crown.
En una realización, la máquina carrusel comprende un mecanismo de cierre y corte de bolsas paquete que comprende una pieza soporte acoplable a una parte de la estructura fija de la máquina carrusel, la cual sustenta dispositivos de soldadura y corte de las bolsas paquete. Dicha pieza soporte también sustenta un dispositivo de retirada del sobrante configurada para sujetar la embocadura del paquete por encima de la línea de corte una vez que es soldada y antes de ser cortada.
