Pallet ligero de cartón reutilizado.Light reused cardboard pallet.
Sector de la técnica en que se encuadra la invenciónSector of the art in which the invention is framed
La presente invención se refiere a un pallet de bajo coste que puede fabricarse a partir de cartón ondulado reutilizado.The present invention relates to a low cost pallet that can be manufactured from reused corrugated cardboard.
Estado de la técnicaState of the art
Actualmente se conocen diversas patentes y modelos de utilidad pallets que resultan más costosas por no estar fabricadas con material reutilizado.Various patents and utility models are currently known, which are more expensive because they are not made from reused material.
En el documento PCT/US2004/040373 se propone un pallet de un solo uso que presenta el inconveniente de resultar complicado de fabricar y montar y de necesitar planchas completas de cartón ondulado fabricadas para tal fin.Document PCT / US2004 / 040373 proposes a single-use pallet that has the drawback of being complicated to manufacture and assemble and of needing complete corrugated cardboard sheets manufactured for this purpose.
En el documento PCT/ES2001000447 se describe un pallet en el que las patas necesitan 2 planchas de fijación adicionales a la superficie de carga y el encolado de 2 capas completas de cartón ondulado de primer uso.Document PCT / ES2001000447 describes a pallet in which the legs need 2 additional fixing plates to the loading surface and the gluing of 2 complete layers of first-use corrugated cardboard.
Explicación de la invenciónExplanation of the invention
El pallet objeto de invención utiliza como materia prima principal cartón ondulado procedentes de la fragmentación de embalajes usados y desechados.The pallet object of the invention uses corrugated cardboard as the main raw material from the fragmentation of used and discarded packaging.
El pallet tiene una superficie de carga compuesta por un núcleo que tiene un recubrimiento superior y otro inferior de papel de alta resistencia o de cartón liso o de cartón ondulado.The pallet has a loading surface consisting of a core that has an upper and a lower covering of high-strength paper or plain cardboard or corrugated cardboard.
El núcleo está formado por refuerzos tubulares de cartón ondulado de diversas calidades y espesores, fabricados a partir de recortes rectangulares planos de cartón que tienen una altura igual al espesor del núcleo. Los refuerzos son independientes entre sí cuando son fabricados, y una vez curvados o plegados, adquieren forma de figuras geométricas tridimensionales con las bases abiertas y paralelas, los cuales, una vez agrupados, quedarán unidos con adhesivo por las aristas de ambas bases a los recubrimientos superior e inferior.The core consists of corrugated cardboard tubular reinforcements of various qualities and thicknesses, made from flat rectangular cardboard cutouts that have a height equal to the thickness of the core. The reinforcements are independent of each other when they are manufactured, and once they are curved or folded, they take the form of three-dimensional geometric figures with the bases open and parallel, which, once grouped, will be joined with adhesive by the edges of both bases to the coatings. upper and lower.
Para dar una mayor resistencia a la flexión, los refuerzos forman preferentemente un patrón tal que todo plano ficticio perpendicular a la superficie de carga situado en su interior corta a varios refuerzos, evitando crear líneas que favorezcan el plegado, si bien también será válido un patrón ordenado que no cumpla con la condición anterior.To give greater resistance to bending, the reinforcements preferably form a pattern such that any dummy plane perpendicular to the load surface located inside cuts several reinforcements, avoiding the creation of lines that favor folding, although a pattern will also be valid ordered not to meet the above condition.
Los refuerzos son estables frente al vuelco para que puedan deslizar y posicionarse agrupados de forma muy sencilla cuando son empujados, facilitando el proceso de fabricación. Además, el sistema de empuje puede agrupar, comprimir y deformar los refuerzos en un plano paralelo a la superficie de carga, lo que puede incrementar el número de refuerzos que forman el núcleo contribuyendo a una mayor resistencia de la superficie de carga.The reinforcements are stable against overturning so they can slide and position grouped very easily when pushed, facilitating the manufacturing process. In addition, the push system can group, compress, and deform the stiffeners in a plane parallel to the load surface, which can increase the number of stiffeners that make up the core, contributing to increased strength of the load surface.
Las ventajas que presenta este pallet respecto a otros pallets de cartón o madera son una mayor ligereza proporcionada al emplear refuerzos huecos, un menor coste de fabricación al poder utilizar como materia prima principal material de desecho en lugar de panchas de cartón, un menor impacto ambiental al evitar un ciclo completo de reciclado en fábrica para producir planchas de cartón y la posibilidad de automatizar la fabricación de la superficie de carga utilizando un sistema de encolado automático de las bases de los refuerzos y un sistema de alimentación de gran capacidad que empuje en bloque un conjunto de refuerzos en un canal del mismo ancho que el pallet, sin necesidad de ordenarlos ni posicionarlos, para después adherir los recubrimientos (2).The advantages of this pallet compared to other cardboard or wooden pallets are a greater lightness provided by using hollow reinforcements, a lower manufacturing cost by being able to use waste material instead of cardboard sheets as the main raw material, a lower environmental impact by avoiding a complete cycle of recycling in the factory to produce cardboard sheets and the possibility of automating the manufacture of the loading surface using an automatic gluing system of the bases of the reinforcements and a system of large capacity feeding that pushes a set of reinforcements in a channel in the same width as the pallet, without the need to order or position them, and then adhere the coatings (2).

Exposición detallada de un modo de realizaciónDetailed exposition of an embodiment
A continuación se describen la superficie de carga (1) y las patas del pallet.The following describes the loading surface (1) and the pallet legs.
Las patas del pallet son de cartón, están adheridas a la superficie de carga (1) y pueden ser de sección rectangular, cuadrada, circular o de cualquier tipo conocido.The pallet legs are made of cardboard, are adhered to the loading surface (1) and can be rectangular, square, circular or of any known type.
La superficie de carga (1) del pallet puede ser cuadrada o rectangular y está formada por un núcleo (3) que tiene adheridas en su cara inferior y superior unas láminas de papel o unas planchas de cartón a modo de recubrimiento (2) que sirven para proporcionar a la superficie de carga (1) resistencia a la flexión y un correcto acabado visual.The loading surface (1) of the pallet can be square or rectangular and is made up of a core (3) that has sheets of paper or cardboard plates as cover (2) attached to its lower and upper face that serve to provide the loading surface (1) with flexural strength and a correct visual finish.
Preferiblemente, los refuerzos (4) que conforman el núcleo (3) están orientados y posicionados en sentido aleatorio y contactando entre sí para facilitar el proceso de fabricación y para evitar la formación de patrones ordenados que generen posibles líneas débiles con una menor resistencia a flexión. Estas líneas se producirán cuando un plano ficticio perpendicular a la superficie de carga (1), situado en su interior, quede tangente a un gran número de refuerzos (4).Preferably, the reinforcements (4) that make up the core (3) are oriented and positioned in a random direction and contacting each other to facilitate the manufacturing process and to avoid the formation of ordered patterns that generate possible weak lines with less flexural resistance . These lines will be produced when a fictitious plane perpendicular to the loading surface (1), located inside it, is tangent to a large number of reinforcements (4).
Teniendo en cuenta que la resistencia a flexión de la superficie de carga (1) dependerá de su espesor, la forma tridimensional de tipo tubular de los refuerzos (4) supone una gran ventaja al permitir la fabricación de superficies de carga de gran espesor sin un incremento significativo de peso.Taking into account that the flexural resistance of the loading surface (1) will depend on its thickness, the tubular three-dimensional shape of the reinforcements (4) is a great advantage in allowing the manufacture of very thick loading surfaces without a significant weight gain.
Los refuerzos (4) se fabricarán curvando o doblando recortes rectangulares planos y podrán tener diversas formas, tanto cerradas como abiertas, pudiendo existir en ambos casos un gran número de posibilidades.The reinforcements (4) will be made by bending or bending flat rectangular cutouts and may have various shapes, both closed and open, and in both cases there may be a large number of possibilities.
En el primer caso, los refuerzos se fabricarán curvando o doblando los recortes y añadiendo adhesivo a una arista perpendicular a las bases. Los refuerzos podrán tener sección con forma circular, de “P”, cuadrada, triangular o hexagonal, entre otras.In the first case, the reinforcements will be made by bending or bending the cutouts and adding adhesive to an edge perpendicular to the bases. The reinforcements may have a circular, "P", square, triangular or hexagonal section, among others.
En el segundo caso. Los refuerzos se fabricarán cunando o doblando los recortes y podrán tener sección con forma de de espiral, de zigzag, etc. In the second case. The reinforcements will be made by cradling or folding the cutouts and may have a spiral, zigzag, etc. section.
La forma de los refuerzos (4) o la forma de combinar refuerzos (4) de diferentes formas debe ser tenida en cuenta para tratar de maximizar la superficie de las bases de los refuerzos (4) en contacto con los recubrimientos (2), así como para evitar la formación de patrones con posibles líneas débiles por las que pueda flexionar la superficie de carga (1) siempre que sea posible. Es por esto por lo que siempre resultará preferible un refuerzo con sección en forma de espiral frente a uno circular, ya que existirá un mayor contacto con los refuerzo (2) y además la parte libre del extremo de la espiral tenderá a tapar huecos y a cortar posibles líneas débiles.The shape of the reinforcements (4) or the way of combining reinforcements (4) in different ways must be taken into account to try to maximize the surface area of the bases of the reinforcements (4) in contact with the coatings (2), thus as to avoid the formation of patterns with possible weak lines through which it can flex the loading surface (1) whenever possible. This is why a reinforcement with a spiral-shaped section will always be preferable to a circular one, since there will be greater contact with the reinforcements (2) and also the free part of the end of the spiral will tend to cover gaps and cut possible weak lines.
En primer lugar se describe una posibilidad preferente en la que los refuerzos son de cartón ondulado. Esta posibilidad cuenta con la ventaja económica que supone poder usar una mezcla de cartones desechados como materia prima, así como la gran resistencia a compresión que presenta el cartón ondulado para los espesores habituales de la superficie de un pallet.Firstly, a preferred possibility is described in which the reinforcements are made of corrugated cardboard. This possibility has the economic advantage of being able to use a mixture of discarded cardboard as raw material, as well as the great resistance to compression that corrugated cardboard presents for the usual thickness of the surface of a pallet.
Debido a que la resistencia de la superficie de carga (1) depende de la resistencia proporcionada por el adhesivo a las uniones entre los refuerzos (4) y los recubrimientos (2), el uso de cartón corrugado supone una gran ventaja frente al uso de cartón sencillo al incrementarse la superficie de contacto entre las bases de los refuerzos (4) y los recubrimientos (2) y por tanto la cantidad de adhesivo admitido.Since the resistance of the loading surface (1) depends on the resistance provided by the adhesive to the joints between the reinforcements (4) and the coatings (2), the use of corrugated cardboard is a great advantage over the use of Simple cardboard as the contact surface between the bases of the reinforcements (4) and the coatings (2) increases and therefore the amount of adhesive allowed.
Para incrementar la resistencia a compresión de la superficie de carga (1), el ondulado del cartón de los refuerzos (4) se orientará perpendicularmente a su base.To increase the compressive strength of the loading surface (1), the corrugated cardboard of the reinforcements (4) will be oriented perpendicular to its base.
En este tipo de refuerzos, el cartón ondulado que los forma ha podido sufrir una reducción de espesor en el proceso de curvado, siendo igualmente válidos.In this type of reinforcements, the corrugated cardboard that forms them has been able to undergo a reduction in thickness in the bending process, being equally valid.
Una segunda posibilidad de realización consiste en una pallet cuyos refuerzos (4) son de cartón liso o que tiene una mezcla de refuerzos (4) de cartón liso y de cartón ondulado, si bien la resistencia de la superficie de carga (1) sería inferior a la de una superficie de carga (1) equivalente con todos los refuerzos (4) de cartón ondulado debido a la menor cantidad admisible de adhesivo y a la menor resistencia a compresión del cartón sencillo frente al cartón ondulado. Esta posibilidad presenta la ventaja de permitir la fabricación de pallets más ligeros. A second possibility of realization consists of a pallet whose reinforcements (4) are made of plain cardboard or that have a mixture of reinforcements (4) of smooth cardboard and corrugated cardboard, although the resistance of the loading surface (1) would be less to that of an equivalent loading surface (1) with all corrugated cardboard reinforcements (4) due to the lower admissible amount of adhesive and the lower compressive strength of plain cardboard compared to corrugated cardboard. This possibility has the advantage of allowing the manufacture of lighter pallets.
En todos los casos el pallet podrá estar fabricado a partir de cartón nuevo, tanto liso como corrugado, lo que permitirá que los pallets estén libres de toda suciedad y puedan ser utilizados en industrias con altos requisitos de higiene, tal como industrias alimentarias.In all cases, the pallet may be made from new cardboard, both smooth and corrugated, which will allow the pallets to be free of all dirt and can be used in industries with high hygiene requirements, such as food industries.
En todos los casos la superficie de carga (1) puede presentar unos recubrimientos (2) adicionales, consistentes en láminas de papel o de cartón liso u ondulado adheridas externamente a los recubrimientos (2) en toda su superficie, que incrementarán la resistencia a flexión y mejorarán el acabado visual.In all cases, the loading surface (1) can have additional coatings (2), consisting of sheets of paper or smooth or corrugated cardboard externally adhered to the coatings (2) on their entire surface, which will increase the flexural resistance and will improve the visual finish.
En todos los casos las láminas de recubrimiento (2) pueden cubrir también las caras laterales del núcleo (3) para proporcionar una mayor resistencia a flexión y un mejor acabado visual. In all cases, the covering sheets (2) can also cover the lateral faces of the core (3) to provide greater flexural resistance and a better visual finish.
En todos los casos el pallet puede disponer de cantoneras (5) adheridas a las caras laterales de la superficie de carga (1). Las cantoneras (5) pueden tener forma rectangular, de "L”, o de "U” y sirven para proporcionar un mejor acabado visual y para incrementar la resistencia a flexión de la superficie de carga.In all cases, the pallet can have corners (5) attached to the lateral faces of the loading surface (1). The butts (5) can be rectangular, "L", or "U" shaped and serve to provide a better visual finish and to increase the flexural resistance of the loading surface.
En todos los casos el pallet puede disponer de uno o varios soportes de unión (6) situados en el interior de la superficie de carga paralelamente a uno de sus lados a lo largo de toda su longitud. Los soportes de unión (6) son de cartón, tienen la misma altura que el núcleo, pueden tener forma rectangular, de "U” o de tubo de sección cuadrada, y se encuentran unidos simultáneamente mediante adhesivo a los dos recubrimientos (2) y a los refuerzos (4) que contactan tangencialmente con ellos. Los soportes de unión (6) tienen la finalidad de incrementar el número de uniones en las zonas que sufren un mayor esfuerzo a compresión o a flexión de la superficie de carga (1). Tales como la zona media y las más alejadas de las patas.In all cases, the pallet may have one or more joint supports (6) located inside the loading surface parallel to one of its sides along its entire length. The union supports (6) are made of cardboard, have the same height as the core, can be rectangular, "U" or tube with a square section, and are joined simultaneously by means of adhesive to the two coatings (2) and to the reinforcements (4) that contact tangentially with them. The joint supports (6) have the purpose of increasing the number of joints in the areas that suffer a greater stress in compression or flexion of the load surface (1). Such as the middle area and those furthest from the legs.
En todos los casos el núcleo (3) puede tener una lámina intermedia (7) del tamaño de la superficie de carga (1) que esté posicionada a medio espesor del núcleo y que contribuya a la mejora de la resistencia. En este caso, el núcleo (3) dispondrá de dos capas de refuerzos (4). In all cases, the core (3) can have an intermediate sheet (7) of the size of the loading surface (1) that is positioned at half the thickness of the core and that contributes to improving resistance. In this case, the core (3) will have two layers of reinforcements (4).
En todos los casos los refuerzos (4) podrán ser de formas, tamaños y calidades iguales o en cualquier combinación de ellos.In all cases the reinforcements (4) may be of the same shapes, sizes and qualities or in any combination of them.
En todos los casos los refuerzos (4) pueden tener cortes en sus aristas perpendiculares a su base que faciliten el plegado al disminuir tensiones internas que se generan en las aristas de pliegue.In all cases, the reinforcements (4) can have cuts at their edges perpendicular to their base that facilitate folding by reducing internal stresses that are generated at the fold edges.
En todos los casos el núcleo (3) puede disponer de refuerzos macizos (8) de cartón de sección similar a cualquier refuerzo de tipo tubular con el fin de incrementar la fuerza de la unión entre el núcleo y los recortes. In all cases, the core (3) can have solid cardboard reinforcements (8) similar in section to any tubular-type reinforcement in order to increase the strength of the bond between the core and the cutouts.
