MECANISMO DE UNIÓN POR ULTRASONIDO ENTRE PARTES PLEGABLES DE UN CONTENEDOR PLÁSTICO Y MÉTODO ASOCIADO ULTRASOUND JOINT MECHANISM BETWEEN FOLDING PARTS OF A PLASTIC CONTAINER AND ASSOCIATED METHOD
MEMORIA DESCRIPTIVA DESCRIPTIVE MEMORY
CAMPO DE LA INVENCION FIELD OF THE INVENTION
La presente invención tiene aplicación en el campo de las cajas plásticas plegables utilizadas para el almacenamiento y transporte de productos hortofrutícolas. En particular, se refiere a mejoras en los mecanismos de unión de las paredes de dichas cajas plegables. The present invention has application in the field of folding plastic boxes used for the storage and transport of fruit and vegetable products. In particular, it refers to improvements in the mechanisms for joining the walls of said folding boxes.
ANTECEDENTES DE LA INVENCION BACKGROUND OF THE INVENTION
En la industria de embalaje y transporte, específicamente durante la exportación de productos hortofrutícolas, es frecuente la utilización de contenedores de plástico del tipo caja rectangular o cuadrada, las cuales son construidas usualmente mediante inyección de plástico y están formadas por un fondo unido a cuatro paredes perimetrales, en donde dichas paredes son plegables o abatibles respecto al fondo, permitiendo que los contenedores puedan ser apilados en una condición desarmada y con ello disminuir la altura de las unidades durante el almacenamiento, requiriendo así menos espacio para estos fines en bodegas o sitios de acopio. In the packaging and transport industry, specifically during the export of fruit and vegetable products, it is common to use plastic containers of the rectangular or square box type, which are usually built by plastic injection and are formed by a bottom joined to four walls perimeter, where said walls are foldable or collapsible with respect to the bottom, allowing the containers to be stacked in a disassembled condition and thereby reducing the height of the units during storage, thus requiring less space for these purposes in warehouses or storage sites. gathering.
Un aspecto importante en los contenedores plásticos plegables tiene que ver con el mecanismo de unión entre las paredes, puesto que este debe ser lo suficientemente fuerte para evitar que se abra involuntariamente producto de las fuerzas que ejercen los productos sobre las caras internas del contenedor durante el transporte y almacenamiento. Al mismo tiempo, el mecanismo de unión debe ser liviano y utilizar una cantidad de material apropiada que no suponga un aumento innecesario en los costes de fabricación del contenedor. An important aspect in folding plastic containers has to do with the joining mechanism between the walls, since this must be strong enough to prevent it from opening unintentionally as a result of the forces exerted by the products on the internal faces of the container during the process. transportation and storage. At the same time, the attachment mechanism must be lightweight and use an appropriate amount of material that does not lead to an unnecessary increase in the cost of manufacturing the container.
Tradicionalmente, los mecanismos de unión para paredes de contenedores de plástico se construyen con el contenedor y como parte del mismo durante el proceso de inyección, formando una sola pieza. Ejemplos de este tipo de mecanismo de cierre se divulgan por ejemplo en el registro de patente CL56058 o en la solicitud de patente CL201802093. En ambos casos, se proponen mecanismos de unión integrados a las paredes del contenedor que consisten en medios de cierre activos y pasivos con una configuración machihembrada de modo que al acoplarse mecánicamente entre ellos, impiden el movimiento relativo entre las paredes del contenedor, permitiendo que estas se mantengan en posición vertical. Traditionally, the joining mechanisms for plastic container walls are built with the container and as part of it during the injection process, forming a single piece. Examples of this type of closing mechanism are disclosed for example in patent registration CL56058 or in patent application CL201802093. In both cases, joining mechanisms integrated to the container walls are proposed, consisting of active and passive closing means with a tongue and groove configuration so that when mechanically coupled between them, they prevent relative movement between the container walls, allowing them to remain in an upright position.
El inconveniente con los mecanismos de unión descritos anteriormente, es que requieren de operaciones complejas desde el punto de vista operacional para el armado de los contenedores. Por ejemplo, los contenedores de paredes plegables se utilizan generalmente para la exportación de productos hortofrutícolas. Estos se envían desde el fabricante hasta el lugar de empacado en una configuración plegada con el fin de reducir el volumen de transporte y así poder transportar una mayor cantidad de contenedores por lote (usualmente en pallets). Luego en el lugar de empaque, estos deben ser desplegados y armados para que puedan ser llenados con los productos hortofrutícolas previo a su envío al destino final. The drawback with the joining mechanisms described above is that they require complex operations from the operational point of view for the assembly of the containers. For example, folding wall containers are generally used for the export of fruit and vegetable products. These are shipped from the manufacturer to the packing point in a folded configuration in order to reduce the volume of transport and thus be able to transport a greater number of containers per batch (usually on pallets). Then in the packing place, these must be deployed and assembled so that they can be filled with the fruit and vegetable products prior to their shipment to the final destination.
Con los mecanismos de unión mecánicos como los del estado del arte, se requieren varios pasos y movimientos durante el proceso de armado del contenedor en el lugar de empaque, para lograr acoplar los medios de cierre machihembrados y conectar las paredes, operación que generalmente se realiza manualmente. With the mechanical joining mechanisms such as those of the state of the art, several steps and movements are required during the assembly process of the container in the place of packaging, to achieve coupling the tongue and groove closing means and connect the walls, an operation that is generally performed manually.
Otra desventaja es que el propio mecanismo de cierre mecánico representa una proporción importante de la cantidad de material que requiere el contenedor para ser construido, influyendo por tanto en el peso final del mismo. Another disadvantage is that the mechanical closing mechanism itself represents a significant proportion of the amount of material that the container requires to be built, thus influencing its final weight.
Es por tanto el objetivo de la presente invención superar los inconvenientes que poseen los mecanismos de unión de paredes de contendores plegables mecánicos antes mencionados, por medio de un mecanismo mejorado que facilite la operación de armado de contenedores plegables y al mismo tiempo permita la utilización de menos material con la consecuente reducción del peso final de tales contenedores. It is therefore the objective of the present invention to overcome the drawbacks that the previously mentioned mechanical folding container wall joining mechanisms have, by means of an improved mechanism that facilitates the folding container assembly operation and at the same time allows the use of less material with the consequent reduction of the final weight of such containers.
DESCRIPCION DE LA INVENCION DESCRIPTION OF THE INVENTION
La presente invención consiste en un mecanismo de unión entre partes plegables de un contenedor plástico, que comprende: un primer medio conductor fundible por ultrasonido en una primera zona de contacto entre dos partes del contenedor; y/o un segundo medio conductor fundible por ultrasonido en una segunda zona de contacto entre dos partes del contenedor. De acuerdo a una modalidad de la invención, dicha primera zona de contacto se encuentra entre dos paredes adyacentes del contendor. Además, dicho primer medio conductor es al menos un nervio alargado que recorre verticalmente una cara de al menos una pared del contenedor, correspondiente a la primera zona de contacto. The present invention consists of a joining mechanism between folding parts of a plastic container, comprising: a first conductive means meltable by ultrasound in a first contact zone between two parts of the container; and / or a second conductive medium meltable by ultrasound in a second contact zone between two parts of the container. According to one embodiment of the invention, said first contact zone is located between two adjacent walls of the container. Furthermore, said first conductive means is at least one elongated rib vertically running along one face of at least one wall of the container, corresponding to the first contact zone.
De acuerdo a una modalidad de la invención, dicha segunda zona de contacto se encuentra entre una pared y el fondo del contendor. Además, dicho segundo medio conductor consiste en: una protuberancia que sobresale de al menos una pared del contenedor; y una abertura ubicada en al menos una esquina del fondo del contenedor, configurada para recibir a dicha protuberancia.According to one embodiment of the invention, said second contact zone is located between a wall and the bottom of the container. Furthermore, said second conductive means consists of: a protrusion protruding from at least one wall of the container; and an opening located in at least one corner of the bottom of the container, configured to receive said protrusion.
Mediante las características del mecanismo de unión anteriormente descrito, se evita el uso de medios mecánicos que requieren de varias operaciones para unir las paredes del contenedor y que incrementan el peso final del mismo. A diferencia, la presente invención introduce el concepto de soldadura por ultrasonido, mediante la cual se funden los medios conductores y unen las partes del contenedor (pared-pared y/o pared-fondo). By virtue of the characteristics of the previously described joining mechanism, the use of mechanical means that require several operations to join the container walls and that increase the final weight of the container is avoided. In contrast, the present invention introduces the concept of ultrasound welding, by means of which the conductive means melt and join the parts of the container (wall-wall and / or wall-bottom).
Ventajosamente, este concepto aporta mayor rigidez y resistencia al contenedor, al estar soldada en varios puntos, a diferencia de los mecanismos mecánicos del estado del arte, donde las partes plegables del contenedor se unen en un sólo punto. Advantageously, this concept provides greater rigidity and resistance to the container, as it is welded at several points, unlike the mechanical mechanisms of the state of the art, where the folding parts of the container are joined at a single point.
La implementación del mecanismo de unión propuesto mediante soldadura por ultrasonido, para el armado de contenedores de plástico, se puede realizar de forma manual o automática. Por ejemplo, en la modalidad automática se puede disponer de una armadora de contenedores plásticos que incorpore una herramienta de ultrasonido para fundir los medios conductores del contenedor y soldar sus partes. The implementation of the union mechanism proposed by means of ultrasonic welding, for the assembly of plastic containers, can be carried out manually or automatically. For example, in the automatic mode you can have a plastic container assembly machine that incorporates an ultrasound tool to melt the conductive means of the container and weld its parts.
Luego y de acuerdo a un segundo aspecto de la presente invención, se propone un método para unir partes plegables de un contenedor plástico por medio de una herramienta de ultrasonido, que comprende: aplicar ultrasonido mediante dicha herramienta a un primer medio conductor ubicado en una primera zona de contacto entre dos partes del contenedor; y/o aplicar ultrasonido mediante dicha herramienta a un segundo medio conductor ubicado en una segunda zona de contacto entre dos parte del contenedor. Then and according to a second aspect of the present invention, a method is proposed to join folding parts of a plastic container by means of an ultrasound tool, which comprises: applying ultrasound by means of said tool to a first conductive means located in a first contact area between two parts of the container; and / or applying ultrasound by means of said tool to a second conductive medium located in a second contact zone between two parts of the container.
De acuerdo a una modalidad de la invención, la herramienta de ultrasonido genera presión a través de al menos una pared del contenedor que entra en contacto directo con el primer medio conductor. Da acuerdo a una modalidad de la invención, la herramienta de ultrasonido entra en contacto directo con el segundo medio conductor. According to one embodiment of the invention, the ultrasound tool generates pressure through at least one wall of the container that comes into direct contact with the first conductive medium. According to one embodiment of the invention, the ultrasound tool comes into direct contact with the second conductive medium.
