La invención se refiere a una máquina conformadora de envases de cartón, del tipo ya conocido, que cuenta con al menos una estación de conformado de envases de cartón donde se ubican dos machos, cada uno con su correspondiente molde, entre los que se posicionan sendas láminas de cartón de forma que, al desplazarse verticalmente cada uno de los machos hacia el molde correspondiente, se conforma el cuerpo del envase, que es expulsado interiormente, como suele ser habitual. The invention refers to a cardboard packaging forming machine, of the already known type, which has at least one cardboard packaging forming station where two cores are located, each one with its corresponding mold, between which paths are positioned. sheets of cardboard in such a way that, when each of the cores moves vertically towards the corresponding mould, the body of the container is formed, which is ejected from the inside, as is usual.
La configuración de las caras del macho y la configuración de los elementos del molde hacen posible que se pueda trabajar indistintamente con cartón ondulado o laminado sin peligro de que este se estropee o se rompa. The configuration of the faces of the core and the configuration of the elements of the mold make it possible to work interchangeably with corrugated or laminated cardboard without the risk of it being damaged or broken.
La estación de conformado de la máquina conformadora de envases de cartón, es alimentada por un transportador 9 de láminas que son extraídas de una zona de apilamiento 7 mediante un sistema de ventosas 6. The forming station of the cardboard packaging forming machine is fed by a conveyor 9 with sheets that are extracted from a stacking area 7 by means of a system of suction cups 6.
La máquina trabaja con placas de cartón laminar de tipo bandeja, mediante las que se conforman los envases, que permanecen abiertos una vez conformados para ser cerrados después de su llenado. The machine works with tray-type laminar cardboard plates, through which the containers are shaped, which remain open once shaped to be closed after filling.
En una utilización típica, los envases se emplean como recipientes para unidades de venta en la industria agrícola. In typical use, the packages are used as unit-of-sale containers in the agricultural industry.
La novedad que incorpora la máquina de la invención consiste en el mecanismo de accionamiento 1 del sistema de ventosas 6 sincronizado mecánicamente con el transportador 9 de láminas de cartón. Según se puede ver en las figuras, la máquina representada incorpora dos estaciones de conformado que son alimentadas de láminas de cartón mediante los sistemas de ventosas 6 de sendos mecanismos de accionamiento 1 a través de los empujadores 10 del transportador 9. Las láminas son extraídas de la zona de apilamiento 7 por el sistema de ventosas 6 de cada uno de los mecanismos de accionamiento 1 para ser depositadas sobre unos raíles 5 para ser desplazadas mediante unos empujadores 10 ubicados en el transportador 9, que se desplazará con un sistema sincronizado con el mecanismo de accionamiento 1 del sistema de ventosas 6 y depositarán cada una de las láminas en la zona de conformado entre el molde y el macho 12 correspondiente para ser conformadas. The novelty that the machine of the invention incorporates consists of the actuation mechanism 1 of the suction cup system 6 mechanically synchronized with the conveyor 9 of cardboard sheets. As can be seen in the figures, the represented machine incorporates two forming stations that are fed cardboard sheets by means of suction cup systems 6 of respective drive mechanisms 1 through pushers 10 of conveyor 9. The sheets are extracted from the stacking area 7 by the system of suction cups 6 of each of the drive mechanisms 1 to be deposited on rails 5 to be moved by pushers 10 located on the conveyor 9, which will move with a system synchronized with the mechanism drive 1 of the suction cup system 6 and will deposit each of the sheets in the forming area between the mold and the corresponding male 12 to be shaped.
El molde, no representado para no complicar los gráficos, dispone de los clásicos elementos formadores fijos y de elementos formadores móviles, topes regulables, cuya posición respecto a los elementos del molde y al macho se puede modificar en función de las características del cartón empleado y del tamaño del envase, entre otros factores. The mould, not represented so as not to complicate the graphics, has the classic fixed forming elements and mobile forming elements, adjustable stops, whose position with respect to the mold elements and the core can be modified depending on the characteristics of the cardboard used and the size of the container, among other factors.
Por su parte, según se representan en las figuras 7 y 8, los machos 12 se disponen sobre un puente fijo 13 y son accionados por un servomotor 11 de forma individual, lo que permite una mayor precisión de movimientos y una facilidad superior a la hora de regular su deslazamiento vertical en función de los diferentes formatos de caja. For their part, as represented in figures 7 and 8, the taps 12 are arranged on a fixed bridge 13 and are individually actuated by a servomotor 11, which allows greater precision of movement and greater ease at the hour. to regulate its vertical displacement according to the different box formats.
Con respecto al nuevo mecanismo de accionamiento 1, tal y como se puede ver en detalle en la figura 2, la máquina dispone de un motor 4 encargado de imprimir movimiento a dos discos 2. Cada disco 2, a través de un tirante 101 , se une al respectivo mecanismo 1. Para ello, uno de los extremos de cada tirante 101 se une a un disco 2 de forma descentrada y el otro extremo se une a un soporte 102 del mecanismo 1. Regarding the new drive mechanism 1, as can be seen in detail in figure 2, the machine has a motor 4 in charge of printing movement to two discs 2. Each disc 2, through a tie rod 101, is attached to the respective mechanism 1. To do this, one of the ends of each tie rod 101 is attached to a disc 2 in an off-center manner and the other end is attached to a support 102 of the mechanism 1.
El soporte 102 puede pivotar alrededor del eje de una rueda dentada fija 103 sobre la que engrana una cadena que también está unida a otra rueda dentada giratoria 104, solidaria a un eje que es el brazo 105 del sistema de ventosas 6. El brazo 105 es el encargado de transmitir el movimiento del mecanismo 1 al sistema de ventosas 6, para lo que está unido a un bastidor donde se encuentran ubicadas las ventosas. De esta forma, se obtiene un movimiento compuesto en el que el sistema de ventosas 6 se mueve verticalmente y cambia el plano de ataque, tal y como se representa en las figuras 3 a 6 donde se muestran diferentes posiciones del recorrido que realiza, desde la posición de recogida de las laminas de cartón a donde son desplazadas desde la zona de apilamiento 7, definida por un par de placas entre las que se ubican las láminas, hasta una posición horizontal del sistema de ventosas 6 para depositar las láminas verticalmente en la zona de conformado. The support 102 can pivot around the axis of a fixed toothed wheel 103 on which a chain meshes that is also attached to another rotating toothed wheel 104, integral with an axis that is the arm 105 of the suction cup system 6. The arm 105 is the one in charge of transmitting the movement of the mechanism 1 to the suction cup system 6, for which it is attached to a frame where the suction cups are located. In this way, a compound movement is obtained in which the suction cup system 6 moves vertically and changes the plane of attack, as represented in figures 3 to 6. where different positions of the route it makes are shown, from the position of collecting the cardboard sheets to where they are moved from the stacking zone 7, defined by a pair of plates between which the sheets are located, to a horizontal position of the suction cup system 6 to deposit the sheets vertically in the forming area.
Sin embargo, con el dispositivo descrito, hay veces que, debido a los movimientos tan rápidos del sistema de ventosas 6, se generan molestas vibraciones, al comportarse los dos sistemas de ventosas 6 como mecanismos independientes, cuando realmente van sincronizados en sus funciones esenciales. However, with the device described, there are times when, due to the rapid movements of the suction cup system 6, annoying vibrations are generated, as the two suction cup systems 6 behave as independent mechanisms, when they are really synchronized in their essential functions.
Con el objetivo de aportar rigidez al dispositivo, evitar estas vibraciones y ganar en suavidad de funcionamiento, se ha creado una nueva forma de realización, según se representa en la figura 9. En esta forma de realización, los brazos 105 de los dos sistemas de ventosas 6 están unidos, formando el nuevo brazo único 106, a la vez que los centros de rotación de las ruedas dentadas fijas 103 que activan los sistemas de ventosas 6 también han sido unidos por un eje común 107. El brazo único 106 y el eje común 107 están unidos por una zona intermedia de su longitud mediante un elemento de unión 14. Además, el eje común 107 también está fijado, con capacidad de rotación, a un apoyo central 15 que está fijado al chasis de la máquina con el objetivo de aportar rigidez y estabilidad al nuevo mecanismo generado. Este apoyo central 15 está configurado como dos pletinas atravesadas por el eje común 107 para mantener al elemento de unión 14 entre ellas, que están unidas por una tercera pletina mediante la que el apoyo centran 5 se une al chasis de la máquina. In order to provide rigidity to the device, avoid these vibrations and improve smoothness of operation, a new embodiment has been created, as represented in figure 9. In this embodiment, the arms 105 of the two support systems suction cups 6 are joined, forming the new single arm 106, while the centers of rotation of the fixed sprockets 103 that activate the suction cup systems 6 have also been joined by a common axis 107. The single arm 106 and the shaft common axis 107 are joined by an intermediate zone of their length by means of a union element 14. In addition, the common axis 107 is also fixed, with the capacity of rotation, to a central support 15 that is fixed to the chassis of the machine with the aim of provide rigidity and stability to the new generated mechanism. This central support 15 is configured as two plates traversed by the common axis 107 to maintain the connecting element 14 between them, which are joined by a third plate through which the central support 5 is attached to the chassis of the machine.
