DISPOSICIÓN DE CAJAS DE POLIESTIRENO EXPANDIDO (EPS) AGRUPADAS EN UNA TORRE SOBRE UN PAEEET ARRANGEMENT OF EXPANDED POLYSTYRENE (EPS) BOXES GROUPED IN A TOWER ON A PAEEET
MEMORIA DESCRIPTIVA DESCRIPTIVE MEMORY
CAMPO DE LA INVENCION FIELD OF THE INVENTION
La presente invención tiene aplicación en la industria del transporte y almacenamiento. En particular, en el transporte y almacenamiento de alimentos tales como pescado fresco, en contendores de Poliestireno Expandido. The present invention finds application in the transportation and storage industry. In particular, in the transport and storage of food such as fresh fish, in Expanded Polystyrene containers.
ANTECEDENTES DE LA INVENCION BACKGROUND OF THE INVENTION
En la industria de transporte y embalaje de alimentos, específicamente de productos frescos tales como pescado, se utilizan contenedores o cajas elaborados a partir de Poliestireno Expandido (EPS) ya que la formulación de sus resinas está libre de compuestos bromados y aditivos contaminantes. In the food transport and packaging industry, specifically for fresh products such as fish, containers or boxes made from Expanded Polystyrene (EPS) are used since the formulation of its resins is free of brominated compounds and polluting additives.
Por ejemplo, en países como Brasil existe una cadena logística creada para la venta de salmón, en la que la unidad de venta a los clientes finales es una caja de EPS de 70 Ib. Cuando este tipo de producto se transporta hacia su destino final o punto de venta, generalmente las cajas son cargadas en camiones frigoríficos que mantienen la cadena de frío o temperatura óptima del producto para evitar su descomposición. For example, in countries like Brazil there is a logistics chain created for the sale of salmon, in which the unit of sale to final customers is a 70 Ib EPS box. When this type of product is transported to its final destination or point of sale, the boxes are generally loaded into refrigerated trucks that maintain the cold chain or optimum temperature of the product to prevent it from decomposing.
En este sentido, el documento WO 2019/157607 divulga una disposición de cajas de EPS agrupadas en una torre sobre un pallet, donde dichas cajas están distribuidas en al menos 7 filas compuestas cada una por tres cajas separadas entre ellas mediante una separación y ordenadas en una configuración de apilamiento cruzado o cross-stacking. La caja está compuesta por un cuerpo rectangular que posee una abertura superior y por una tapa, en donde el cuerpo posee una base con ranuras de apilamiento y la tapa comprende proyecciones de apilamiento. La caja posee aproximadamente un largo de 800 mm, un ancho de 400 mm y una altura de 300 mm con un volumen interior de 61 L. In this sense, document WO 2019/157607 discloses an arrangement of EPS boxes grouped in a tower on a pallet, where said boxes are distributed in at least 7 rows each consisting of three boxes separated from each other by a separation and arranged in a cross-stacking or cross-stacking configuration. The box is made up of a rectangular body having a top opening and a lid, where the body has a base with stacking slots and the lid comprises stacking projections. The box is approximately 800 mm long, 400 mm wide and 300 mm high with an internal volume of 61 L.
La caja y configuración de apilamiento propuesta en el documento WO 2019/157607, permite la distribución de cajas en pallets estándar de l,2m x 0,8m, asegurando que las cajas quedan apoyadas sobre el 100% de su base, permitiendo una óptima distribución de las cargas de peso y al mismo tiempo un flujo de refrigeración adecuado al interior del camión. Sin embargo, se ha detectado que las dimensiones que debe tener la caja propuesta en el documento antes señalado para cumplir con las condiciones de transporte, poseen inconvenientes. En particular, debido al gran tamaño que tienen los salmones chilenos producto de los avances tecnológicos en la industria acuícola, el largo de 800 mm que tiene la caja no es suficiente para disponer en forma totalmente estirada el pescado en su interior, debiendo colocarse flectados, lo cual provoca dificultades en la operación y desperdicio de espacio útil al interior de la caja. The box and stacking configuration proposed in document WO 2019/157607, allows the distribution of boxes on standard pallets of 1.2m x 0.8m, ensuring that the boxes are supported on 100% of their base, allowing optimal distribution of weight loads and at the same time an adequate refrigeration flow to the interior of the truck. However, it has been detected that the dimensions that the box proposed in the aforementioned document must have to comply with the transport conditions have drawbacks. In particular, due to the large size of Chilean salmon as a result of technological advances in the aquaculture industry, the 800 mm length of the box is not enough to fully stretch the fish inside it, and must be placed flexed, which causes difficulties in the operation and waste of useful space inside the box.
Es por tanto el objetivo de la presente invención superar este inconveniente, por medio de una caja y configuración mejorada para el transporte y almacenamiento de productos alimenticios frescos, de una manera más adecuada para el tamaño de los salmones cultivados en Chile. It is therefore the objective of the present invention to overcome this drawback, by means of an improved box and configuration for the transport and storage of fresh food products, in a way more suitable for the size of salmon farmed in Chile.
DESCRIPCIÓN DE LA INVENCIÓN DESCRIPTION OF THE INVENTION
Para lograr el objetivo antes mencionado, se propone una caja de Poliestireno expandido (EPS) para el transporte y almacenamiento de alimentos, la cual comprende un cuerpo rectangular que posee una abertura superior y una tapa. El cuerpo de la caja posee una base con ranuras de apilamiento y la tapa comprende proyecciones de apilamiento, estas últimas estando configuradas para encastrar con las ranuras de apilamiento de la base. To achieve the aforementioned objective, an expanded polystyrene (EPS) box is proposed for the transport and storage of food, which comprises a rectangular body that has a top opening and a lid. The box body has a base with stacking slots and the lid comprises stacking projections, the latter being configured to engage with the stacking slots in the base.
La caja comprende un largo en el rango de 800 a 1.200 mm, un ancho en el rango de 200 a 600 mm y una altura en el rango entre 150 y 350 mm. Preferentemente, la caja tiene un largo total de 1.000 mm, un ancho de 400 mm y una altura de 250 mm. Con estas dimensiones, se obtiene una disposición de cajas agrupadas en una torre sobre un pallet de 1.200 mm de largo por 1.000 mm de ancho, donde dichas cajas están distribuidas en al menos 9 filas compuestas cada una por tres cajas dispuestas paralelamente una al lado de la otra y a lo largo del pallet (Fig. 5). De acuerdo a una modalidad, el ancho de la caja es 397, dejando así una holgura de 6 mm entre dos cajas adyacentes para permitir el armado automatizado de la torre por medio de robots. The box comprises a length in the range of 800 to 1,200 mm, a width in the range of 200 to 600 mm and a height in the range of 150 to 350 mm. Preferably, the box has a total length of 1,000 mm, a width of 400 mm and a height of 250 mm. With these dimensions, an arrangement of boxes grouped in a tower is obtained on a pallet 1,200 mm long by 1,000 mm wide, where said boxes are distributed in at least 9 rows, each one composed of three boxes arranged in parallel, one next to each other. the other and along the pallet (Fig. 5). According to one embodiment, the width of the box is 397, thus leaving a clearance of 6 mm between two adjacent boxes to allow automated erection of the tower by robots.
A partir de estas especificaciones, se obtiene una caja del mismo ancho que las utilizadas en el estado del arte pero que es más larga y más baja, manteniendo el volumen y por tanto no afectando la capacidad de almacenamiento, es decir, se logra mantener la unidad de venta para no afectar los procesos y la cadena logística existente. Based on these specifications, a box of the same width as those used in the state of the art is obtained, but which is longer and lower, maintaining the volume and therefore not affecting the storage capacity, that is, it is possible to maintain the sales unit so as not to affect the processes and the existing logistics chain.
Para el apilamiento de las cajas, se propone utilizar pallets de EPS por temas de higiene y aislamiento térmico. Sobre este se distribuyen las cajas ordenadas de la forma anteriormente descrita. Además, el pallet comprende en su cara superior proyecciones de apilamientos configuradas para encastrar con las cajas que se disponen inmediatamente sobre él. For the stacking of the boxes, it is proposed to use EPS pallets for hygiene and thermal insulation issues. On this are distributed the boxes ordered in the way above described. In addition, the pallet comprises on its upper face stacking projections configured to engage with the boxes that are placed immediately on it.
Gracias al uso del pallet de EPS, las cajas del nivel inferior quedan sobre una superficie completamente aislada del piso del camión evitando el calentamiento y derretimiento del producto. Por su parte, el uso de este elemento en combinación con el ordenamiento de cajas propuesto optimiza el flujo de aire frío alrededor de las cajas. Thanks to the use of the EPS pallet, the boxes on the lower level remain on a completely isolated surface from the truck floor, preventing heating and melting of the product. For its part, the use of this element in combination with the proposed box arrangement optimizes the flow of cold air around the boxes.

De acuerdo con la Figura 2a, el cuerpo 10 comprende al menos un refuerzo de pared 11 dispuesto en al menos una cara de al menos una pared lateral para aumentar la resistencia a la compresión de dicha pared. El cuerpo de refuerzo de pared 11 además comprende una zona de soporte de pared 12 dispuesta hacia la abertura del cuerpo 10 de la caja. Por su parte, la abertura del cuerpo 10 comprende un borde perimetral 13, que corresponde a un borde hacia arriba de la abertura y que es para la conexión con la tapa. Por otra parte, se aprecia que el cuerpo 10 comprende perforaciones verticales 14 hacia las cuatro esquinas del cuerpo, esquineros 15 dispuestos hacia las esquinas superiores del cuerpo 10 y al menos un rebaje inferior dispuesto en la cara exterior del cuerpo 10, definiendo una superficie de agarre 16. De acuerdo con la Figura 2b, la cara inferior del cuerpo de la caja comprende una superficie proyectada 17 preferentemente en forma de cruz que le da una mayor resistencia a la caja, limitando la deformación del fondo por el peso de los productos en su interior. Además, cerca del borde de la cara inferior del cuerpo, se dispone una configuración de rebajes de apilamiento 18 configurados para recibir proyecciones de apilamiento dispuestas en la cara exterior de la tapa. Preferentemente los rebajes de apilamiento tienen la forma de un canal continuo. According to Figure 2a, the body 10 comprises at least one wall reinforcement 11 arranged on at least one face of at least one side wall to increase the compressive strength of said wall. The wall reinforcing body 11 further comprises a wall support area 12 arranged towards the opening of the box body 10. For its part, the opening of the body 10 comprises a perimeter edge 13, which corresponds to an upward edge of the opening and is for connection with the lid. On the other hand, it can be seen that the body 10 comprises vertical perforations 14 towards the four corners of the body, corner pieces 15 arranged towards the upper corners of the body 10 and at least one lower recess arranged on the outer face of the body 10, defining a surface of grab 16. According to Figure 2b, the lower face of the box body comprises a projecting surface 17 preferably in the shape of a cross that gives the box greater resistance, limiting the deformation of the bottom due to the weight of the products inside. Also, near the edge of the lower face of the body, a pattern of stacking recesses 18 configured to receive stacking projections provided on the outer face of the lid is provided. Preferably the stacking recesses are in the form of a continuous channel.
Finalmente, en los bordes inferiores del fondo de la caja se disponen sacados inferiores 19 que proveen una superficie para el paso de los zunchos que permiten asegurar las cajas en el pallet. Preferentemente, se dispone un par de sacados inferiores 19 en cada borde longitudinal inferior de la caja. Finally, on the lower edges of the bottom of the box there are lower recesses 19 that provide a surface for the passage of the straps that allow the boxes to be secured on the pallet. Preferably, a pair of lower pockets 19 are provided at each lower longitudinal edge of the box.
En la Figura 3a se muestran las proyecciones de apilamiento 21 que emergen desde la cara superior de la tapa 20 y que son complementarias con las ranuras de apilamiento que posee la cara exterior del fondo del cuerpo ilustradas en la Figura 3a. De acuerdo con la modalidad ilustrada, la tapa también comprende sacados superiores 22 que están alineados con los sacados inferiores del cuerpo de la caja y que tienen también el propósito de permitir el paso de zunchos. Figure 3a shows the stacking projections 21 that emerge from the upper face of the lid 20 and that are complementary to the stacking slots on the outer face of the bottom of the body illustrated in Figure 3a. According to the illustrated embodiment, the lid also comprises upper recesses 22 that are aligned with the lower recesses of the box body and that also have the purpose of allowing the passage of straps.
Cabe señalar que los rebajes y proyecciones de apilamiento que poseen respectivamente el cuerpo y la tapa pueden tener cualquier forma complementaria entre sí y/o estar ubicados en cualquier parte de su superficie. En el ejemplo ilustrado se tiene que el rebaje y la proyección tienen forma de canal y resalte continuo o semi continuo, pero pueden ser también protuberancias configuradas para encajar en perforaciones. Por ejemplo, las mismas podrían estar ubicadas en las esquinas de la tapa y cuerpo e incluso pueden estar intercambiadas, es decir, las proyecciones emerger del fondo de la caja para introducirse en rebajes ubicados en la tapa. It should be noted that the stacking recesses and projections that the body and the lid have respectively can have any shape complementary to each other and/or be located on any part of their surface. In the illustrated example, the recess and the projection have the shape of a continuous or semi-continuous channel and projection, but they can also be protuberances configured to fit into perforations. For example, they could be located in the corners of the lid and body and can even be interchanged, that is, the projections emerge from the bottom of the box to enter into recesses located in the lid.
Por su parte, la Figura 3b ilustra los detalles de la cara inferior de la tapa 20, donde se puede apreciar que esta comprende una ranura perimetral 23 para recibir el borde perimetral del cuerpo de la caja. La tapa 20 además comprende una estructura de refuerzo 24 preferentemente con forma de cruz y que busca incrementar la resistencia a la flexión de la tapa.

For this, the upper face of the pallet has three support areas 33 circumscribed by a rim 34 that has the shape of the base of a box and is configured so that the boxes are deposited inside it, preventing their movement in relation to the pallet. In addition, the support areas 23 have a slight separation between them to create the space that allows the entry of the pallets of a robot that assembles the tower of boxes on the pallet.
De acuerdo a la Figura 5, el ordenamiento que se propone en la presente invención es un apilamiento con tres cajas 100 por fila, dispuestas paralelamente unas al lado de la otra, de modo que la pared larga de las cajas es perpendicular al lado más largo del pallet 20. Preferentemente la torre está conformada por 9 filas de cajas, dándole a la torre la altura adecuada para su transporte en camiones frigoríficos. According to Figure 5, the arrangement proposed in the present invention is a stack with three boxes 100 per row, arranged parallel to each other, so that the long wall of the boxes is perpendicular to the longest side. of pallet 20. Preferably, the tower is made up of 9 rows of boxes, giving the tower the appropriate height for its transport in refrigerated trucks.
Como fue señalado anteriormente, el armado de la torre de cajas puede ser completamente automatizado por medio del uso de robots. Para ello, se deja una separación entre cajas para que puedan entrar y salir las paletas del robot que arma la torre. Dicha separación es preferentemente menor a 10 mm y más preferentemente, de 3 mm. Además, dicha separación está considerada en el diseño de las cajas, de modo que las dimensiones de la torre calzan justo con las del pallet. As noted above, the assembly of the box tower can be fully automated through the use of robots. To do this, a separation is left between boxes so that the pallets of the robot that assembles the tower can enter and exit. Said separation is preferably less than 10 mm and more preferably, 3 mm. In addition, this separation is considered in the design of the boxes, so that the dimensions of the tower fit exactly with those of the pallet.
Finalmente, la Figura 6 muestra una modalidad alternativa de la invención, en donde se dispone una tapa o parrilla 40 sobre la tapa de las cajas 100 ubicadas en la fila superior, con el fin de evitar la separación de las tres columnas de cajas dispuestas sobre el pallet 20. Preferentemente, la tapa o parrilla se afianza al pallet por medio de zunchos o amarras (no ilustradas) que recorren la altura completa de las cajas. Finally, Figure 6 shows an alternative embodiment of the invention, where a lid or grill 40 is arranged on the lid of the boxes 100 located in the upper row, in order to avoid the separation of the three columns of boxes arranged on top. the pallet 20. Preferably, the lid or grill is secured to the pallet by means of bands or ties (not illustrated) that run the full height of the boxes.
