Pallet ligero de cartón reutilizado.Lightweight cardboard pallet reused.
Sector de la técnica en que se encuadra la invenciónSector of the technique 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.Currently, several patents and utility models are known that are more expensive because they are not manufactured with 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.In PCT / US2004 / 040373 a single-use pallet is proposed, which has the disadvantage of being complicated to manufacture and assemble and of needing corrugated board sheets manufactured for that 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.In the document PCT / ES2001000447 a pallet is described in which the legs require 2 additional fixing plates to the loading surface and the gluing of 2 full layers of corrugated cardboard of first use.
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 from the fragmentation of used and discarded packaging as the main raw material.
El pallet tiene una superficie de carga (1) compuesta por un núcleo (3) que tiene un recubrimiento (2) superior y otro inferior de papel de alta resistencia o de cartón liso o de cartón ondulado.The pallet has a loading surface (1) composed of a core (3) having an upper (2) and lower covering of high strength paper or plain cardboard or corrugated cardboard.
El núcleo está formado por refuerzos (4) 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 (3). Los refuerzos (4) 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 (2) superior e inferior. Para dar una mayor resistencia a la flexión, los refuerzos (4) forman preferentemente un patrón tal que todo plano ficticio perpendicular a la superficie de carga (1) 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.The core is formed by reinforcements (4) tubular corrugated cardboard of various qualities and thicknesses, manufactured from flat rectangular cardboard cutouts that have a height equal to the thickness of the core (3). The reinforcements (4) are independent of each other when they are manufactured, and once curved or folded, they take the form of three-dimensional geometric figures with open and parallel bases, which, once grouped, will be joined with adhesive by the edges of both bases to the top and bottom coatings (2). To give a greater resistance to bending, the reinforcements (4) preferably form a pattern such that every fictitious plane perpendicular to the loading surface (1) located in its interior cuts to several reinforcements, avoiding creating lines that favor folding, if An ordered pattern that does not comply with the previous condition will also be valid.
Los refuerzos (3) 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 (1), lo que puede incrementar el número de refuerzos que forman el núcleo (3) contribuyendo a una mayor resistencia de la superficie de carga (1).The reinforcements (3) are stable against overturning so that they can slide and position grouped in a very simple way when pushed, facilitating the manufacturing process. In addition, the thrust system can group, compress and deform the reinforcements in a plane parallel to the load surface (1), which can increase the number of reinforcements that form the core (3) contributing to a greater resistance of the surface Load (1).
Las ventajas que presenta este pallet respecto a otros pallets de cartón o madera son una mayor ligereza proporcionada al emplear refuerzos (4) 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 (1) utilizando un sistema de encolado automático de las bases de los refuerzos (4) y un sistema de alimentación de gran capacidad que empuje en bloque un conjunto de refuerzos (4) 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 pallets of cardboard or wood are a greater lightness provided by employing hollow reinforcements (4), a lower manufacturing cost to be able to use as waste raw material instead of cardboard chips, a lower environmental impact by avoiding a complete recycling cycle in the factory to produce cardboard sheets and the possibility of automating the manufacture of the surface of loading (1) using a system of automatic gluing of the bases of the reinforcements (4) and a system of feeding of great capacity that pushes in block a set of reinforcements (4) in a channel of the same width that the pallet, without necessity to order them or to position them, to later adhere the coatings (2).
Breve descripción de los dibujosBRIEF DESCRIPTION OF THE DRAWINGS
En la figura 1 se representa un pallet ligero de cartón reutilizado con una superficie de carga (1) formada por un núcleo (3) de refuerzos (4) tubulares con forma de espiral. El núcleo (3) tiene un recubrimiento (2) superior y otro inferior.Figure 1 shows a light pallet of reused cardboard with a loading surface (1) formed by a core (3) of spiral-shaped tubular reinforcements (4). The core (3) has an upper covering (2) and a lower one.

The loading surface (1) has two corners (5) and a rectangular joint support (6) which is adhered to the reinforcements (4) that contact it and to the lower cover (2).
En la figura 3 se representan refuerzos (4) de diversas formas, tanto abiertos como cerrados: en espiral, circular, con forma de “P” o en zigzag. Cuatro son de cartón ondulado y uno de cartón liso.In figure 3 reinforcements (4) are represented in various forms, both open and closed: spiral, circular, "P" or zigzag. Four are corrugated cardboard and one is plain cardboard.
Exposición detallada de un modo de realizaciónDetailed description of an embodiment
A continuación se describen la superficie de carga (1) y las patas del pallet.Next, the loading surface (1) and the legs of the pallet are described.
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 legs of the pallet are made of cardboard, they 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 formed by a core (3) having on its lower and upper side adhered sheets of paper or cardboard sheets as a covering (2) that serve to provide the load 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 sense and contacting each other to facilitate the manufacturing process and to avoid the formation of ordered patterns that generate possible weak lines with a lower resistance to bending . These lines will occur when a fictitious plane perpendicular to the load 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 strength of the load surface (1) will depend on its thickness, the tubular-type three-dimensional shape of the reinforcements (4) is a great advantage in allowing the manufacture of very thick load surfaces without a significant increase in weight.
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 manufactured by bending or folding flat rectangular cuts and may have various forms, both closed and open, and there may be a large number of possibilities in both cases.
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 manufactured by bending or folding the cuttings and adding adhesive to an edge perpendicular to the bases. Reinforcements may have a circular section, "P", square, triangular or hexagonal, among others.
En el segundo caso. Los refuerzos se fabricarán curvando o doblando los recortes y podrán tener sección con forma de de espiral, de zigzag, etc. In the second case. The reinforcements will be manufactured by bending or folding the cut-outs and they will be able to have a section with a spiral, zigzag, etc. shape.
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 flexional' 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) of different shapes must be taken into account in order to maximize the surface of the reinforcement bases (4) in contact with the coverings (2), as well as to avoid the formation of patterns with possible weak lines by which the load surface (1) can flexional whenever possible. This is why it will always be preferable to use a reinforcement with a spiral section in front of a circular one, since there will be greater contact with the reinforcement (2) and also the free part of the end of the spiral will tend to cover holes 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.First, 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 a raw material, as well as the high compressive strength of corrugated cardboard for the usual thicknesses 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.Because 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 single board as the contact surface between the reinforcement bases (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 load surface (1), the corrugation of the reinforcement board (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 of 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 of smooth cardboard or which has a mixture of reinforcements (4) of smooth cardboard and corrugated cardboard, although the resistance of the loading surface (1) would be lower to that of an equivalent loading surface (1) with all the reinforcements (4) of corrugated cardboard due to the lower admissible amount of adhesive and the lower compressive strength of the single cardboard versus the 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 can be manufactured from new cardboard, both smooth and corrugated, which will allow the pallets are 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 adhered externally to the coatings (2) over its entire surface, which will increase the resistance to bending and 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 side faces of the core (3) to provide a greater resistance to bending 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) adhered to the side faces of the loading surface (1). The corners (5) may have a rectangular shape, "L", or "U" and serve to provide a better visual finish and to increase the flexural strength 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 can have one or several joint supports (6) located inside the loading surface parallel to one of its sides along its entire length. The joint supports (6) are made of cardboard, have the same height as the core, can be rectangular, "U" or square section tube, and are simultaneously attached by adhesive to the two coatings (2) and the reinforcements (4) that They contact tangentially with them. The attachment supports (6) have the purpose of increasing the number of joints in the areas that suffer a greater compressive or flexion stress of the load surface (1), such as the middle zone and those furthest away 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 load surface (1) that is positioned at half the thickness of the core and that contributes to the improvement of the strength. 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 reinforcements (4) can have cuts in their edges perpendicular to their base to facilitate folding by reducing internal stresses that are generated in the edges of the fold.
En todos los casos el núcleo (3) puede disponer de un refuerzo macizo (8) 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. Este refuerzo macizo podrá ser fabricado mediante pegado de varios recortes de cartón ondulado o mediante el enrollado de una tira rectangular de cartón y pegado a lo largo de todo su desarrollo. In all cases, the core (3) can have a solid reinforcement (8) with a section similar to any reinforcement of tubular type in order to increase the strength of the connection between the core and the cuts. This solid reinforcement can be manufactured by gluing several cutouts of corrugated cardboard or by winding a rectangular strip of cardboard and gluing it throughout its development.
