PALETIZADOR AUTOMÁTICO DE TAPAS RETRACTILADAS O AUTOMATIC PALLETIZER OF RETRACTED TOPS OR
EMBOLSADAS EN PAPELPAPER PACKAGING
D E S C R I P C I Ó ND E S C R I P C I O N
OBJETO DE LA INVENCIÓNOBJECT OF THE INVENTION
La presente invención se refiere a un paletizador automático especialmente concebido para tapas metálicas, como las tapas utilizadas para cerrar botes de conserva, tapas previamente adecuadas formando cartuchos o paquetes en los que un grupo de tapas queda estabilizado mediante una envuelta de un film micro- perforado y termo-retráctil, o embolsado de papel.The present invention relates to an automatic palletizer specially designed for metal lids, such as the lids used to close canisters, previously suitable lids forming cartridges or packages in which a group of lids is stabilized by a sheath of a micro-perforated film. and thermo-shrink, or paper bagging.
El objeto de la invención es conseguir un paletizador que permita disponer sobre el correspondiente palet cartuchos de tapas formando filas dobles, es decir que en cada fila participen al menos dos cartuchos de tapas, quedando además orientada la cara exterior de la tapa hacia el exterior del palet, en orden a que quede protegida la cara interior que, en definitiva, es la que va a estar en contacto con el alimento.The object of the invention is to achieve a palletizer that allows cartridges of lids to be arranged on the corresponding pallet forming double rows, that is to say in each row at least two cartridges of lids, the outer face of the lid being oriented towards the outside of the pallet, in order to protect the inner face that, ultimately, is the one that will be in contact with the food.
Evidentemente el paletizador es igualmente utilizable en el caso de que las alineaciones de cartuchos de tapas sean triples o cuádruples.Obviously the palletizer is equally usable in the case that the cartridge line-up of lids is triple or quadruple.
ANTECEDENTES DE LA INVENCIÓNBACKGROUND OF THE INVENTION
Los paletizadores automáticos de tapas formando cartuchos retractilados o embolsados en papel conocidos hasta la fecha están concebidos para cartuchos de tapas cuya longitud coincide con la anchura del palet.The automatic palletizers of lids forming shrink-wrapped or paper-bagged cartridges known until the date are designed for cartridges of covers whose length matches the width of the pallet.
Esto trae consigo una problemática con una doble vertiente, por un lado cada cartucho de tapas ofrece al exterior la cara externa de una de ellas y la cara interna de otra, de manera que existe un cierto riesgo de que el envoltorio termo-retráctil en su zona correspondiente al interior de las tapas extremas se rompa, contaminándose dichas tapas que como anteriormente se ha dicho están destinadas a entrar en contacto con los alimentos por su cara interna, mientras que por otro lado la longitud de estos cartuchos resulta en muchas ocasiones excesivamente grande, existiendo en la actualidad una exigencia del mercado para que estos cartuchos de tapas sean longitud mitad de lo que es convencional, o lo que es lo mismo, mitad de la anchura del palet.This brings with it a problem with a double slope, on the one hand each cap cartridge offers the external face of one of them and the internal face of another, so that there is a certain risk that the shrink wrap in its zone corresponding to the interior of the end caps is broken, contaminating said covers that as previously said are destined to come into contact with food by its internal face, while on the other hand the length of these cartridges is often too large , currently there is a demand from the market for these capsules to be half the length of what is conventional, or what is the same, half the width of the pallet.
Los paletizadores actuales no son capaces ni de hacer filas dobles de cartuchos en un mismo palet, ni de orientar de distinta manera los dos cartuchos de cada alineación, para que las tapas muestren al exterior tan sólo su cara externa.The current palletisers are not able to make double rows of cartridges in the same pallet, nor to orientate the two cartridges of each alignment in different ways, so that the covers show only their external face.
DESCRIPCIÓN DE LA INVENCIÓNDESCRIPTION OF THE INVENTION
El paletizador automático que la invención propone resuelve de forma plenamente satisfactoria la problemática anteriormente expuesta.The automatic palletizer proposed by the invention solves in a fully satisfactory manner the problem previously discussed.
Para ello y de forma mas concreta, a partir de la estructuración básica de cualquier paletizador automático convencional de este tipo, la invención se centra en el hecho de que dicho paletizador incorpora un pórtico por el que es longitudinalmente desplazable un carro, convenientemente motorizado, sobre el que a su vez se desplaza un patín, con un movimiento perpendicular al anterior igualmente motorizado, patín en el que participa un soporte para un brazo manipulador desplazable verticalmente y rematado por su extremidad inferior en una garra magnética, capaz de girar sobre el propio eje del brazo manipulador.For this and in a more specific way, starting from the basic structuring of any conventional automatic palletizer of this type, the invention focuses on the fact that said palletizer incorporates a gantry through which a carriage, suitably motorized, is longitudinally movable, on which a skate moves, with a movement perpendicular to the previous one, equally motorized, a skate in which a support for a vertically movable manipulator arm participates and topped by its lower extremity in a magnetic claw, capable of rotating on the axis of the manipulator arm itself.
De esta manera se consigue para la garra magnética movimientos según los ejes de un sistema de coordenadas cartesianas, así como un cuarto movimiento de giro sobre sí misma, lo que permita a dicha garra tomar de la bandeja de alimentación de cartuchos de tapa dichos cartuchos, preferentemente de dos en dos, y trasladarlos al palet, depositándolos con la orientación adecuada en cada caso.In this way, movements for the magnetic claw are achieved according to the axes of a Cartesian coordinate system, as well as a fourth movement of rotation on itself, which allows said claw to take said cartridges from the lid cartridge feed tray, preferably two by two, and transfer them to the pallet, depositing them with the appropriate orientation in each case.
La garra magnética se materializa en dos filas de imanes permanentes, aproximables a los cartuchos de tapas mediante cilindros neumáticos, fijando dichos cartuchos de tapas merced a la naturaleza metálica de las mismas, y liberándolas cuando los imanes permanentes se separan de los cartuchos por retracción de los mismos debida a los citados cilindros.The magnetic claw is embodied in two rows of permanent magnets, approximate to the cartridges of covers by pneumatic cylinders, fixing said cartridges of caps thanks to the metallic nature of the same, and releasing them when the permanent magnets are separated from the cartridges by retraction of the same due to the aforementioned cylinders.

REALIZACIÓN PREFERENTE DE LA INVENCIÓNPREFERRED EMBODIMENT OF THE INVENTION
En la figura 1, tal como acaba de decirse, se ha representado esquemáticamente y en perspectiva el paletizador automático en su conjunto, y en ella se observa la existencia de una plataforma base (1) a la que tiene acceso un carro (2) portador de los palets (3), de manera que dicho carro (2) y su correspondiente palet quedan enmarcados por una pareja de paneles laterales (4) que mantienen estabilizados sobre el palet los diferentes cartuchos (6) de tapas, mientras se produce la carga de dicho palet (3) y hasta que se produce el definitivo envolvimiento del conjunto con una malla plástica u otro material, suministrada por una bobina (5) situada sobre uno de los paneles (4) a través de soportes (5'), y con las que colabora un carro auxiliar porta-bobinas (7), que actúa como retén ante el agotamiento de una de las bobinas (5) anteriormente citadas, para evitar la interrupción en el proceso operativo del paletizador.In figure 1, as it has just been said, the automatic palletizer as a whole has been represented schematically and in perspective, and in it the existence of a base platform (1) which has access to a carriage (2) carrying the pallets (3), so that said carriage (2) and its corresponding pallet are framed by a pair of side panels (4) that keep stabilized on the pallet the different cartridges (6) of caps, while the loading of said pallet (3) occurs and until the definitive wrapping of the assembly with a plastic mesh or other material is produced, supplied by a coil (5) located on one of the panels (4) through supports (5 '), and with which an auxiliary trolley carrying carriage (7) cooperates, which acts as a seal before the exhaustion of one of the aforementioned coils (5), to avoid the interruption in the palletizer's operating process.
Pues bien, a partir de esta estructuración básica en el paletizador que la invención propone se establece un pórtico (8) que enmarca tanto los mecanismos descritos a la bandeja de alimentaciónWell, from this basic structuring in the palletizer that the invention proposes a gantry (8) is established that frames both the mechanisms described to the feeding tray
(9), definiéndose en dicho pórtico (8) y a nivel superior, dos guías longitudinales (10) sobre las que se desplaza un carro (11) accionado por un servomotor-reductor, definiéndose en dicho carro (11) guías longitudinales (12) que a su vez resultan transversales con respecto a las guías (10) anteriormente citadas, por las que se desplaza un patín(9), defining in said gantry (8) and at the upper level, two longitudinal guides (10) on which a carriage (11) driven by a servomotor-reducer moves, defining longitudinal carriages (12) in said carriage (11). which in turn are transverse with respect to the guides (10) mentioned above, by which a skate moves
(13), también asistido por un servomotor-reductor, en el que juega un brazo manipulador (14), vertical e igualmente motorizado, que se remata por su extremidad superior en una garra magnética (15), la representada en detalle en la figura 3, de manera que dicha garra magnética es susceptible de desplazarse según los tres ejes (x, y, z) de un sistema de coordenadas cartesianas, como anteriormente se ha dicho, y además es susceptible de girar sobre el imaginario eje del brazo (14),(13), also assisted by a servomotor-reducer, in which plays a manipulator arm (14), vertical and equally motorized, which is topped by its upper end in a magnetic claw (15), represented in detail in the figure 3, so that said magnetic gripper is capable of moving according to the three axes (x, y, z) of a Cartesian coordinate system, as previously mentioned, and is also capable of rotating on the imaginary axis of the arm (14). ),
Específicamente tal como muestra la figura 2, el carro (11) se desplaza accionado por un servomotor-reductor (16), el patín (13) lo hace mediante un servomotor-reductor (17), y el brazo (14) mediante un tercer servomotor-reductor (18), mientras que el movimiento de giro para la garra magnética (15) se lleva a cabo mediante otro servomotor-reductor (19).Specifically as shown in figure 2, the car (11) is moved by a servomotor-reducer (16), the skid (13) does so by means of a servomotor-reducer (17), and the arm (14) by means of a third servomotor-reducer (18), while the Turning motion for the magnetic gripper (15) is carried out by another servomotor-reducer (19).
En ésta garra magnética (15) tal como muestra la figura 3, participa un chasis (20) sobre el que se montan cuatro cilindros neumáticos (21) capacitados para desplazar verticalmente a dos filas de imanes permanentes (22), de manera que cuando estos se aproximan a una pareja de cartuchos, o a un solo cartucho (para formar filas impares) (6) de tapas, los fijan debidamente a la garra, mientras que cuando dichos imanes se separan o retraen los cartuchos (6) quedan liberados para ser depositados sobre el palet, en cualquier posición prevista para el mismo, merced a la total capacidad de movimientos que ofrece dicha garra (15).In this magnetic claw (15) as shown in Figure 3, there is a chassis (20) on which are mounted four pneumatic cylinders (21) capable of moving vertically to two rows of permanent magnets (22), so that when these they approach a pair of cartridges, or a single cartridge (to form odd rows) (6) of caps, they fix them properly to the claw, whereas when said magnets are separated or retracted the cartridges (6) are released to be deposited on the pallet, in any position foreseen for it, thanks to the total capacity of movements offered by said claw (15).
Como complemento de la estructura descrita en la garra (15) se establecen superiormente dos parejas de brazos articulados (23) que actúan como amortiguadores frente a cualquier pequeño impacto vertical a la hora de descargar los cartuchos en el palet, evitando el deterioro de dichos cartuchos y, consecuentemente, el deterioro de las tapas.As a complement to the structure described in the claw (15), two pairs of articulated arms (23) are established, acting as shock absorbers against any small vertical impact when unloading the cartridges on the pallet, avoiding the deterioration of said cartridges. and, consequently, the deterioration of the lids.
Finalmente y en cuanto a la bandeja de alimentación (9), la representada en detalle en la figura 4, en ésta se decide una rampa (24) sobre la que "ruedan" los cartuchos de tapas (6), que son retenidos mediante una pareja de cilindros neumáticos (25) que interfieren sobre dicha rampa (24), y que permiten que los cartuchos de tapa (6) pasen de uno en uno a una plataforma horizontal (26), donde a su vez son retenidos y debidamente cuadrados mediante otro cilindro neumático (27), siendo esta plataforma horizontal (26) de donde la garra magnética (15) toma, de dos en dos, o de uno en uno para filas impares los citados cartuchos (6) para trasladarlos al palet (3), sobre el que los sitúa en la posición mostrada en la figura 5, con la cara externa de las tapas extremas orientada hacia fuera. Finally, as for the feeding tray (9), the one depicted in detail in figure 4, in this one a ramp (24) is decided on which "the cartridges" (6) "roll", which are retained by means of a pair of pneumatic cylinders (25) which interfere on said ramp (24), and which allow the lid cartridges (6) to pass one by one to a horizontal platform (26), where in turn are retained and properly squared by another pneumatic cylinder (27), this horizontal platform (26) being where the magnetic claw (15) takes, two by two, or one by one for odd rows the said cartridges (6) to transfer them to the pallet (3), on which it places them in the position shown in figure 5, with the external face of the end caps facing outwards.
