Description
Procedimiento y dispositivo para la fabricación de un envase con una unión en arrastre de forma conformada posteriormente Procedure and device for the manufacture of a container with a trailed joint in a subsequently formed manner
El presente invento trata de un procedimiento y un dispositivo para la fabricación de un envase con una cubeta de envase que puede ser llenada con una mercancía y que está cerrada con una tapa, conectando al menos una unión por arrastre de forma, la cubeta de envase con la tapa y estando la unión compuesta de un primer elemento de unión y un segundo elemento de unión. The present invention deals with a method and a device for the manufacture of a container with a container tray that can be filled with a merchandise and that is closed with a lid, connecting at least one shape drag connection, the container tray with the cover and the joint being composed of a first joint element and a second joint element.
Los envases se componen, por lo general, de una cubeta de envase que puede ser llenada con mercancía, por ejemplo alimentos. Después, la cubeta de envase es cerrada con una tapa generalmente preformada. Para aumentar la fuerza de desprendimiento de la tapa de la cubeta de envase después de la primera apertura, es favorable para el cierre repetitivo, si entre la tapa y la cubeta de envase existe al menos una unión por arrastre de forma. Esta unión por arrastre de forma se compone de dos elementos de unión, por ejemplo, una ranura y un muelle, siendo el muelle introducido en la ranura. The containers are generally made up of a container bucket that can be filled with merchandise, for example food. Then, the container tray is closed with a generally preformed lid. In order to increase the detachment force of the lid of the container tray after the first opening, it is favorable for repetitive closure, if there is at least one shape drag connection between the lid and the container tray. This form drag connection is composed of two connecting elements, for example, a groove and a spring, the spring being inserted into the groove.
Actualmente, los elementos de unión son moldeados en la tapa o en la cubeta de envase durante la embutición profunda. Sin embargo, como después de la embutición profunda la tapa o la cubeta de envase pueden ser desmoldadas nuevamente y un elemento de unión debe poder ser introducido en el otro, en dicho procedimiento se está muy restringido en cuanto a la forma de los elementos de unión. Currently, the joining elements are molded in the lid or in the container tray during deep drawing. However, since after deep drawing the lid or the container tray can be re-demolished and one joining element must be able to be introduced in the other, in said procedure it is very restricted in terms of the shape of the joining elements. .
Los envases en los que la unión por arrastre de forma entre la tapa y la cubeta de envase ha sido moldeada después del cierre de la cubeta de envase mediante la tapa se conocen por los documentos US 1.709.196, DE 1461797, EP 0791538 A1 y EP 1493683. Containers in which the shape drag connection between the lid and the container tray has been molded after the closure of the container tray by means of the lid is known from US 1,709,196, DE 1461797, EP 0791538 A1 and EP 1493683.
Por eso, el objetivo del presente invento es poner a disposición un procedimiento y un dispositivo para la fabricación de envases de este tipo. Therefore, the objective of the present invention is to make available a method and a device for the manufacture of such containers.
El envase se compone de una cubeta de envase que se puede llenar de mercancía, y una tapa. Preferentemente, tanto la cubeta de envase como la tapa están fabricadas de un material plástico y, en cada caso, mediante moldeo profundo. El material plástico puede ser, en comparación, rígido y/o espumado. Entre la tapa y la cubeta de envase están dispuestos al menos una, sin embargo preferentemente, varias uniones por arrastre de forma, actuando el arrastre de forma de manera que aumente la fuerza necesaria para desprender la tapa de la cubeta de envase. Las uniones por arrastre de forma pueden estar distribuidas de cualquier manera sobre la circunferencia del envase. Además, las uniones por arrastre de forma pueden ser combinadas con una articulación, estando, entonces, dispuesta al menos una unión por arrastre de forma opuesta a la bisagra (articulación). Además, las uniones por arrastre de forma también pueden ser usadas como conexión rápida para el nuevo cierre de los envases. La unión por arrastre de forma se compone de un primer elemento de unión y un segundo elemento de unión que engranan uno en el otro y, por lo tanto, producen una unión por arrastre de forma. Como elementos de unión se usan todos los elementos de unión usuales para el experto en la materia, con los cuales es posible conseguir un arrastre de forma entre la cubeta de envase y la tapa. Sin embargo, el elemento de unión es, preferentemente, una conexión muelleranura o dos cubetas esféricas parciales que encajan una en la otra. Preferentemente, la unión se extiende paralela al sentido de transporte de la banda de lámina continua de la que se fabrica la bandeja. Dicha forma de fabricación del presente invento simplifica los útiles o su disposición en una máquina de envasar, necesarios para conformar en la cubeta de envase y/o la tapa, los elementos de unión por arrastre de forma. The container consists of a container bucket that can be filled with merchandise, and a lid. Preferably, both the container tray and the lid are made of a plastic material and, in each case, by deep molding. The plastic material can be, in comparison, rigid and / or foamed. At least one, however preferably, several form trailers are arranged between the lid and the container tray, the drag acting in such a way as to increase the force necessary to detach the lid from the container tray. Shape drag joints may be distributed in any way over the circumference of the container. In addition, the shape drag joints can be combined with a joint, so that at least one drag joint is arranged opposite the hinge (joint). In addition, shape drag joints can also be used as a quick connection for the new closure of the containers. The shape drag joint is made up of a first joint element and a second joint element that engage in one another and, therefore, produce a shape drag connection. As joining elements, all the usual joining elements for the person skilled in the art are used, with which it is possible to achieve a drag between the container tray and the lid. However, the connecting element is preferably a spring connection or two partial spherical cuvettes that fit into each other. Preferably, the joint extends parallel to the direction of transport of the continuous sheet web from which the tray is manufactured. Said form of manufacture of the present invention simplifies the tools or their arrangement in a packaging machine, necessary to form, in the container tray and / or the lid, the form-dragging elements.
El envase presenta al menos una, preferentemente, sin embargo, dos o más uniones por arrastre de forma. The package has at least one, preferably, however, two or more shape drag joints.
Preferentemente, la tapa y la cubeta de envase están selladas una contra la otra en la zona de un plano de sellado. Preferentemente, dicho sellado es desprendible, de modo que el envase pueda ser cerrado nuevamente mediante la unión por arrastre de forma. Preferably, the lid and the container tray are sealed against each other in the area of a sealing plane. Preferably, said seal is removable, so that the package can be closed again by means of the drag-on connection.
Las uniones están incorporadas a la cubeta de envase, preferentemente mediante termoconformado. Preferentemente, la introducción de la unión se produce de interior a exterior, es decir, que en el sector de la unión aumenta la circunferencia del envase. Dicho modelo de fabricación del presente invento tiene la ventaja de que la superficie a través de la que puede extraerse la mercancía no se reduce debido a las conformaciones o que deban fabricarse abombamientos adicionales en los que, posteriormente, se moldean las uniones, como se da a conocer por el documento EP 0 367 603 A2. The joints are incorporated into the container tray, preferably by thermoforming. Preferably, the introduction of the joint takes place from inside to outside, that is to say that in the sector of the union the circumference of the container increases. Said manufacturing model of the present invention has the advantage that the surface through which the merchandise can be extracted is not reduced due to the conformations or that additional bulges must be manufactured in which, subsequently, the joints are molded, as given known from EP 0 367 603 A2.
Preferentemente, el moldeado se encuentra en las paredes laterales de la cubeta de envase. Preferably, the molding is in the side walls of the container tray.
Preferentemente, la tapa está sellada a la cubeta de envase. Preferentemente, dicho sellado es desprendible, de modo que la unión se usa como nuevo cierre después de la primera apertura. Preferentemente, la tapa está sellada a la cubeta de envase a lo largo de un plano de sellado esencialmente horizontal. Preferably, the lid is sealed to the container tray. Preferably, said seal is removable, so that the joint is used as a new closure after the first opening. Preferably, the lid is sealed to the container bucket along an essentially horizontal sealing plane.
Los envases pueden ser envases moldeados de cualquier forma. Sin embargo, en lo esencial los envases presentan, preferentemente, una superficie de base cuadrangular o redonda. The containers can be molded containers of any shape. However, essentially the containers preferably have a square or round base surface.
Este objetivo se consigue mediante un procedimiento según la reivindicación 1. This objective is achieved by a method according to claim 1.
Con el procedimiento según el invento es posible fabricar envases que presentan uniones por arrastre de forma conformadas de cualquier forma entre el envase y la tapa. El procedimiento según el invento es sencillo y realizable económicamente. With the process according to the invention, it is possible to manufacture packages that have drag connections formed in any way between the container and the lid. The process according to the invention is simple and economically realizable.
En un modelo de fabricación preferente entre el procedimiento según el invneto, la tapa es sellada a la cubeta de envase antes de que sea fabricada la unión por arrastre de forma. Preferentemente, el sellado es desprendible. In a preferred manufacturing model between the process according to the invention, the lid is sealed to the container bucket before the shape drag connection is manufactured. Preferably, the seal is removable.
Preferentemente, la fabricación del envase se produce paso a paso; es decir, una formación compuesta varios envases es transportada siempre paso a paso a lo largo de una máquina de envasar. Entonces, el moldeo de las uniones se produce durante una parada de los envases a fabricar. Para ello, un útil que al menos presenta un, preferentemente varios elemento/s de gofrado se desplaza, preferentemente, en sentido vertical. Con dichos elementos de gofrado se fabrican las uniones. Preferably, the manufacturing of the package occurs step by step; that is, a formation consisting of several packages is always transported step by step along a packaging machine. Then, the molding of the unions occurs during a stop of the containers to be manufactured. For this, a tool that at least has one, preferably several embossing elements / s, preferably moves vertically. With said embossing elements the joints are manufactured.
017 Para la propia verdadera fabricación de las uniones, los elementos de gofrado son desplazados, preferentemente, transversales al sentido de transporte de los envases a lo largo de la máquina de envasar y, de este modo, moldean una unión en la cubeta de envase o en la tapa. Después de la fabricación, los elementos de gofrado son retraídos y movidos verticalmente hacia arriba, de modo que los envases puedan ser trasladados un paso más. 017 For the actual manufacture of the joints, the embossing elements are preferably displaced transverse to the direction of transport of the packages along the packaging machine and, thus, shape a joint in the container tray or on the lid. After manufacturing, the embossing elements are retracted and moved vertically upwards, so that the containers can be moved one more step.
Según el invento, los elementos de gofrado interactúan con un contrasoporte, por ejemplo, para impedir que el envase se deforme durante el moldeo de la unión. According to the invention, the embossing elements interact with a counter support, for example, to prevent the package from deforming during the molding of the joint.
Los contrasoportes están dispuestos desplazables verticalmente. Los contrasoportes ascienden en cuanto los envases se encuentran debajo de los elementos de gofrado, de modo que hacen contacto con las cubetas de envase. Antes de que los envases sean trasladados, los contrasoportes descienden nuevamente. The counter supports are arranged vertically movable. The counter supports rise as soon as the containers are under the embossing elements, so that they make contact with the container buckets. Before the containers are moved, the counter supports descend again.
Según el invento, los contrasoportes son girados antes de descender. El objetivo es conseguido, además, por medio de una máquina de envasar según la reivindicación 4. According to the invention, the counter supports are rotated before descending. The objective is also achieved by means of a packaging machine according to claim 4.
Preferentemente, el elemento de gofrado está montado en forma transversal al sentido de transporte de la banda de lámina continua, de manera que pueda encajar, de modo reversible, en la cubeta de envase o en la tapa. Además, está dispuesto desplazable verticalmente, para que después del moldeo de la unión pueda ser retirado del área de envase. Preferably, the embossing element is mounted transversely to the direction of transport of the continuous web, so that it can be reversibly fitted in the container tray or in the lid. In addition, it is arranged vertically movable, so that after molding the joint can be removed from the container area.
La máquina de envasar según el invento trabaja, preferentemente, paso a paso. En este caso, los envases de una formación son trasladados paso a paso en torno a un determinado trayecto. El tratamiento del envase, así como el moldeo de la unión, se produce durante una parada de los envases. The packaging machine according to the invention preferably works step by step. In this case, the containers of a formation are moved step by step around a certain path. The treatment of the container, as well as the molding of the union, occurs during a stop of the containers.
Además, la máquina de envasar según el invento presenta un contrasoporte con el cual interactúan los elementos de gofrado. Mediante dicha realización del presente invento, los elementos de unión de la unión por arrastre de forma pueden ser moldeados más rápido y con mayor exactitud en la cubeta de envase o en la tapa. Además, se previene una deformación del envase durante la fabricación de las uniones. In addition, the packaging machine according to the invention has a counter support with which the embossing elements interact. By means of said embodiment of the present invention, the connection elements of the shape drag connection can be molded faster and more accurately in the container tray or in the lid. In addition, deformation of the package is prevented during the fabrication of the joints.
Dichos contrasoportes están dispuestos desplazables verticalmente. Según el invento, los contrasoportes son girados sobre un eje vertical antes del descenso, hasta que una escotadura existente en el contrasoporte coincida con la unión moldeada. A continuación, es posible un descenso sin problemas del contrasoporte. Said counter supports are arranged vertically movable. According to the invention, the counter supports are rotated on a vertical axis before the descent, until a recess in the counter support coincides with the molded joint. Then, a smooth descent of the counter support is possible.
Preferentemente, la máquina de envasar según el invento presenta una estación de sellado en la que se sella la tapa a la cubeta de envase. Preferentemente, los elementos de gofrado de la estación de sellado, están dispuestos aguas abajo respecto del sentido de marcha de la lámina de la que será fabricada la cubeta de envase y la tapa. Preferably, the packaging machine according to the invention has a sealing station in which the lid is sealed to the container tray. Preferably, the embossing elements of the sealing station are arranged downstream with respect to the direction of travel of the sheet from which the container tray and the lid will be manufactured.

La figura 1 se representa un envase que se compone de una cubeta de envase 2 y una tapa 3. En la cubeta de envase 2 puede colocarse una mercancía, por ejemplo alimentos. A continuación, la cubeta de envase 2 es cerrada mediante la tapa 3. Después que la cubeta de envase ha sido cerrada con la tapa, la unión 4 por arrastre de forma es moldeada en la tapa y/o en la cubeta de envase. En el presente caso, la unión por arrastre de forma es moldeada tanto en la tapa 3 como en la cubeta de envase 2. El envase es fabricado en una máquina de envasar en la que la cubeta de envase o la tapa son colocadas en la máquina de envasar como piezas terminadas, Figure 1 depicts a package consisting of a container tray 2 and a lid 3. A container, for example food, can be placed in the container tray 2. Next, the container cuvette 2 is closed by the lid 3. After the container cuvette has been closed with the lid, the shape-dragged connection 4 is molded into the lid and / or the container cuvette. In the present case, the shape drag connection is molded into both the lid 3 and the container tray 2. The package is manufactured in a packaging machine in which the container tray or lid is placed in the machine. of packaging as finished parts,
- o bien, por ejemplo, moldeadas en una banda de lámina continua mediante estampación profunda. En cada caso, los envases son transportados dentro de una máquina de envasar a lo largo del sentido de marcha indicado por la flecha, preferentemente paso a paso. El experto en la materia puede ver que en el presente caso, la unión 4 por arrastre de forma está dispuesta paralela al sentido de marcha de la máquina de envasar, lo que simplifica considerablemente la configuración de la máquina de envasar, algo que se explica detalladamente mediante las figuras 3 y 4. La tapa y la cubeta de envase son selladas una a la otra en el sector de sellado de manera desprendible, antes de que la unión por arrastre de forma fuera moldeada en el envase. or, for example, molded into a continuous sheet web by deep stamping. In each case, the containers are transported inside a packaging machine along the direction indicated by the arrow, preferably step by step. The person skilled in the art can see that in the present case, the shape drag connection 4 is arranged parallel to the direction of operation of the packaging machine, which considerably simplifies the configuration of the packaging machine, something that is explained in detail by means of figures 3 and 4. The lid and the container tray are sealed to each other in the sealing sector in a removable manner, before the drag-shaped connection was molded into the container.
028 En la figura 2, se ilustran dos formas de configuración posibles de la unión por arrastre de forma. En la representación izquierda se encuentra dibujada una ranura coniforme que se extiende hacia dentro y hacia fuera del plano de papel. Gracias al hecho de que la unión por arrastre de forma sólo sea moldeada a la tapa o a la cubeta de envase una vez que la tapa ha sido colocada sobre la cubeta de envase, es posible realizar formas de la unión por arrastre que no eran posibles de acuerdo con el estado actual de la técnica. Por ejemplo, no era posible fabricar una ranura o muelle agudos, mostrados en la ilustración de la izquierda, sin que ya no hubiesen podido ser desmoldados 028 In Figure 2, two possible configurations of the shape drag connection are illustrated. On the left representation a coniform groove is drawn that extends in and out of the paper plane. Thanks to the fact that the shape drag connection is only molded to the lid or the container tray once the lid has been placed on the container tray, it is possible to make forms of the drag connection that were not possible according to the current state of the art. For example, it was not possible to manufacture an acute groove or spring, shown in the illustration on the left, without having been able to be demoulded.
- o bien no hubiesen sido dañados al unir la tapa y la cubeta de envase. or they would not have been damaged by joining the lid and the container tray.
En la parte derecha de la ilustración 2, se representa una configuración semiesférica de la unión por arrastre de forma. El experto en la materia entiende que de manera favorable, distribuidas sobre la circunferencia de la cubeta de envase, están dispuestas varias uniones esféricas por arrastre de forma de este tipo. Por lo demás, se remite a la realización del modelo de fabricación izquierdo de acuerdo con la figura 2. On the right side of Figure 2, a hemispherical configuration of the shape drag connection is shown. The person skilled in the art understands that in a favorable manner, distributed over the circumference of the container tray, several spherical joints are arranged by such a drag. Otherwise, it refers to the realization of the left manufacturing model according to figure 2.
En la figura 3, se ilustra el elemento de gofrado de una máquina de envasar. La cubeta de envase (no mostrada) cerrada mediante una tapa es transportada al plano del papel y detenida por corto tiempo en las escotaduras 12 del útil 8. En cuanto el envase se encuentre dentro de la escotadura 12 en una posición estacionaria, los elementos de gofrado 5, 6, que se encuentran en elementos de desplazamiento 9, 10, son descendidos o desplazados hacia derecha o izquierda, de modo que entran en contacto con el envase y moldean los elementos de unión respectivos en la tapa o en la cubeta de envase, en lo esencial de manera simultánea. Durante el moldeo, los elementos de gofrado 5, 6 interactúan con contrasoportes 7 que están dispuestos en el útil 8. En cuanto se hubieren fabricado los elementos de unión de la unión por arrastre de forma, dichos útiles son nuevamente movidos hacia atrás y los envases así terminados son trasladados en un paso. El movimiento de los elementos de ajuste 9, 10 está representado mediante las dos flechas dobles. Los elementos de gofrado 5, 6 pueden ser realizados calefaccionables. In Figure 3, the embossing element of a packaging machine is illustrated. The container tray (not shown) closed by a lid is transported to the plane of the paper and stopped for a short time in the recesses 12 of the tool 8. As long as the package is inside the recess 12 in a stationary position, the elements of embossing 5, 6, which are in displacement elements 9, 10, are lowered or moved to the right or left, so that they come into contact with the container and mold the respective joining elements in the lid or in the container tray , essentially simultaneously. During the molding, the embossing elements 5, 6 interact with counter supports 7 which are arranged in the tool 8. As soon as the connection elements of the shape drag connection have been manufactured, said tools are again moved back and the containers Thus finished they are transferred in one step. The movement of the adjustment elements 9, 10 is represented by the two double arrows. The embossing elements 5, 6 can be made heated.
La figura 4 se corresponde en lo esencial con la figura 3, estando en el presente caso ilustradas las mangueras 11 con las cuales se consigue el desplazamiento de los elementos de ajuste 9, 10 transversalmente al sentido de transporte de la banda de lámina continua. Figure 4 corresponds essentially to Figure 3, the hoses 11 being illustrated in the present case with which the displacement of the adjusting elements 9, 10 is achieved transversely to the direction of transport of the continuous sheet web.
La figura 5 muestra una formación de dos hileras, en cada caso con cuatro contrasoportes 7, para la fabricación de los elementos de unión según el invento en envases que están dispuestos en una formación correspondiente. Dichos contrasoportes 7 presentan, en cada caso, una ranura 13 que interactúa con un elemento de gofrado (no mostrado) para gofrar el elemento de unión según el invento en la pared lateral de la cubeta de envase y en la tapa. Además, el contrasoporte según el invento presenta cuatro escotaduras 14 en las que la ranura está interrumpida y que llegan hasta el borde superior del contrasoporte 7. Dos elementos de gofrado calefaccionados (no mostrados) son presionados hacia fuera transversalmente a la dirección de transporte indicada mediante una flecha y gofran de este modo la unión por arrastre de forma en la tapa o la pared lateral de la cubeta de envase. A continuación, los elementos de gofrado son retraídos nuevamente y, al mismo tiempo o poco después, los contraelementos son girados en 45º en el o contra el sentido de las agujas del reloj, hasta que las escotaduras 14 coincidan con las uniones por arrastre de forma en los envases. Después de ello, los contrasoportes 7 pueden ser descendidos sin dañar la unión por arrastre de forma y las cubetas de envase provistas de la unión por arrastre de forma pueden ser trasladadas en un paso. Entre dos pasos, los contrasoportes son girados nuevamente hacia atrás en 45º a su posición inicial y pueden, en cuanto el traslado de las cubetas de envase haya terminado, ser puestos en contacto con otra formación de envases, para insertar en el envase, uniones por arrastre de forma. Figure 5 shows a two-row formation, in each case with four counter supports 7, for the manufacture of the connecting elements according to the invention in packages that are arranged in a corresponding formation. Said counter supports 7 have, in each case, a groove 13 that interacts with an embossing element (not shown) for embossing the connecting element according to the invention on the side wall of the container tray and on the lid. In addition, the counter-support according to the invention has four recesses 14 in which the groove is interrupted and that reaches the upper edge of the counter-support 7. Two heated embossing elements (not shown) are pressed out transversely to the indicated direction of transport by an arrow and embossing the connection by dragging in the lid or the side wall of the container tray. Then, the embossing elements are retracted again and, at the same time or shortly thereafter, the counter-elements are rotated 45 ° in or against the clockwise direction, until the recesses 14 coincide with the drag-out joints. In the containers. After that, the counter-supports 7 can be lowered without damaging the shape drag connection and the container trays provided with the shape drag connection can be moved in one step. Between two steps, the counter supports are turned back again in 45º to their initial position and can, as soon as the transfer of the container buckets is finished, be put in contact with another formation of packages, to insert in the container, unions by drag shape.
En la figura 6, se muestra un corte a través de una serie de contrasoportes 7 y una ampliación B. Se puede ver, In figure 6, a section is shown through a series of counter supports 7 and an extension B. It can be seen,
5 claramente, que los contrasoportes 7 son giratorios sobre un eje vertical 15. Este giro se produce en el presente caso en torno a 45º en el y en contra del sentido de las agujas del reloj respectivamente mediante una correa dentada 17 que se encuentra, en cada caso, en engrane con una rueda dentada 16. El experto en la materia entiende que también se puede usar cualquier otro accionamiento. El experto en la materia entiende que el moldeo de las uniones no necesariamente debe producirse transversalmente al sentido de transporte, sino que también 5 clearly, that the counter-supports 7 are rotatable on a vertical axis 15. This rotation occurs in the present case around 45 ° in and against the clockwise direction respectively by means of a toothed belt 17 which is, in each case, in gear with a 16 cogwheel. The person skilled in the art understands that any other drive can also be used. The person skilled in the art understands that the molding of the joints must not necessarily occur transversely to the direction of transport, but also
10 puede estar dispuesto en cualquier otro lugar. 10 can be arranged anywhere else.
El accionamiento de la correa dentada 17 se muestra en la figura 7. El mismo se produce, en el presente caso, mediante un cilindro neumático 18 que acciona una palanca 19 alternadamente en el y contra el sentido de las agujas del reloj. Dicho accionamiento es transmitido mediante la correa dentada 17 a las diez ruedas dentadas 16 y The drive of the toothed belt 17 is shown in Figure 7. It is produced, in the present case, by a pneumatic cylinder 18 which actuates a lever 19 alternately in and against the clockwise direction. Said drive is transmitted by the toothed belt 17 to the ten sprockets 16 and
15 las acciona de manera sincronizada. El experto en la materia entiende que también se puede usar cualquier otro accionamiento. 15 drives them synchronously. The person skilled in the art understands that any other drive can also be used.
