PROCEDIMIENTO DE FABRICACIÓN Y CAJA PERFECCIONADA CON PICO VERTEDORMANUFACTURING PROCEDURE AND PERFECTED BOX WITH SPILL POINT
La presente invención, procedimiento de fabricación y caja con pico vertedor, consistente en una novedosa y original forma de realizar una caja plegable, constituida a partir de una plancha troquelada, preferentemente de cartón, plegada sobre determinadas líneas de doblado y encolada en determinadas áreas de unión, dando lugar a una caja con forma de paralelepípedo provista de un pico vertedor.The present invention, manufacturing procedure and box with pouring spout, consisting of a novel and original way of making a folding box, consisting of a die-cut sheet, preferably cardboard, folded on certain folding and gluing lines in certain areas of union, giving rise to a parallelepiped-shaped box with a pouring spout.
Por ello, la presente invención será de especial interés para el sector fabricante y suministrador de material de envase y embalaje y en especial para el sector de cajas y embalajes de cartón.For this reason, the present invention will be of special interest to the manufacturer and supplier of packaging and packaging material, and especially to the cardboard box and packaging sector.
Actualmente, el comercio de numerosos productos de consumo, se realiza aprovechando el embalaje de transporte de los mismos, como expendedor, para lo que se facilita la apertura del mismo a los efectos de que sirva como distribuidor. Para ello, una solución conocida es la de las cajas o embalajes provistos de pico vertedor, consistentes en una ventana practicada en la caja provista de una canalización a modo de pico, con utilidad para distribución de los productos contenidos en su interior.Currently, the trade of numerous consumer products is carried out taking advantage of their transport packaging, as a dispenser, for which the opening of the same is facilitated for the purposes of serving as a distributor. For this, a known solution is that of the boxes or packaging provided with a spout, consisting of a window made in the box provided with a spout-like duct, with utility for distribution of the products contained therein.
El problema que resuelve la presente invención radica en la dificultad de realizar el referido pico vertedor en las cajas plegables, constituidas a partir de una plancha troquelada, preferentemente de cartón, plegada sobre determinadas líneas de doblado. La obtención del pico vertedor partiendo del desperdicio que se origina en una solapa lateral superior, como se hace en la presente invención, tiene una mayor complejidad que la obtención del mismo a través del añadido de caras suplementarias, procedimiento conocido en el Estado de la Técnica. Efectivamente, los picos vertedores obtenidos de este último modo se forman mediante el simple pegado lateral de sus caras, mientras que en la invención que se presenta el pico se forma con el gancho del fondo automático, al entrar en colisión el mismo con el borde de la caja y plegarlo hacia el interior de la misma. La complejidad de este procedimiento reside en que el área que genera el pico contiene necesariamente cuatro líneas de hendido paralelas, y que el conjunto, al colisionar con el gancho de fondo automático ha de doblarse necesariamente siempre por la misma, precisamente por la tercera línea de hendido allí marcada.The problem solved by the present invention lies in the difficulty of making the said pour spout in the folding boxes, made from a die-cut sheet, preferably cardboard, folded on certain folding lines. Obtaining the pouring spout from the waste that originates in an upper side flap, as is done in the present invention, has a greater complexity than obtaining it through the addition of additional faces, a procedure known in the State of the Art . Indeed, the pouring spouts obtained in the latter way are formed by simply gluing their faces laterally, while in the invention presented, the spout is formed with the hook of the automatic bottom, when it collides with the edge of the box and fold it towards the inside of it. The complexity of this procedure is that the area that generates the peak necessarily contains four parallel creasing lines, and that the assembly, when colliding with the automatic bottom hook, must always be bent by the same, precisely by the third creasing line marked there.
Esto se consigue abriendo un pasillo en medio de la pieza. El gancho del fondo automático, en lugar de colisionar con el borde externo de la caja, se introduce en dicho pasillo y sobrepasa las dos primeras líneas de hendido sin tropezar con ellas. Al terminarse el pasillo el gancho tropieza con la caja delante de la tercera línea de hendido, que además está realizada de modo que sea más dócil que la cuarta (a base de intercalar pequeños cortes que debilitan el cartón), con lo que conseguimos que el conjunto se doble siempre por la tercera línea.This is achieved by opening a corridor in the middle of the piece. The hook of the automatic bottom, instead of colliding with the outer edge of the box, is inserted into said aisle and passes the first two creasing lines without tripping over them. At the end of the aisle, the hook meets the box in front of the third crease line, which is also made so that it is more docile than the fourth (by inserting small cuts that weaken the cardboard), with which we achieve that the set is always folded by the third line.
Cuando el conjunto se dobla por la tercera línea, las áreas representadas por la parte de la solapa con la que se conforma el pico vertedor, vienen a caer respectivamente sobre su proyección en la cara de la caja y quedan así unidas ya que han sido previamente encoladas. En este punto queda formado el pico vertedor. A continuación la caja sigue su marcha, y es plegada lateralmente por los correspondientes hendidos y finalmente por el hendido y pegada por la solapa de pegado lateral, con lo que alcanza la forma en que será servida al cliente. No obstante, con la caja una vez terminada, es necesario resolver un problema, consistente en que en el lado donde se ha construido el pico vertedor, queda una solapa lateral de doble grosor, unida por sus dos extremos: Por arriba la unión es la tercera línea de hendido y por abajo las áreas que forman el pico vertedor, firmemente pegadas. Cuando el cliente en su planta envasadora deba abatir dicha solapa lateral 90° para cerrar el paquete, se encuentra con que no puede hacerlo, ya que al ser una gruesa doble pared, el recorrido exterior e interior no son idénticos, y los dos extremos están pegados. Para resolver este inconveniente se exagera la docilidad de la tercera línea de hendido a base de practicarle cortes, de modo que se obtiene un triple efecto:When the assembly is folded by the third line, the areas represented by the part of the flap with which the pouring spout is formed, respectively fall on their projection on the face of the box and are thus joined, since they have been previously glued. At this point the pouring spout is formed. The box then continues on its way, and is folded laterally by the corresponding creases and finally by the crease and glued by the side gluing flap, thereby reaching the way it will be served to the customer. However, with the box once finished, it is necessary to solve a problem, consisting in that on the side where the pouring spout has been built, there is a double thickness side flap, joined by its two ends: Above, the union is the third crease line and below the areas that form the pouring spout, firmly attached. When the customer in his packaging plant must fold said lateral flap 90 ° to close the package, he finds that he cannot do it, since being a thick double wall, the outer and inner path are not identical, and the two ends are glued together. To solve this problem, the docility of the third crease line is exaggerated by making cuts, so that a triple effect is obtained:
- Conseguir que la figura donde se construye el pico doble siempre por dicha línea. - Alcanzar la máxima precisión posible a la hora de superponer la solapa que forma el pico vertedor sobre la cara lateral de la caja a la que se encola. Esta característica es de gran importancia, pues de ello depende que no existan rendijas en las paredes del pico vertedor. - Lograr que al abatir la doble solapa lateral en la planta de envasado, la tercera línea se rasgue y el borde inferior compense su recorrido más corto sobresaliendo un par de mm. aproximadamente, y libere así la tensión que de otro modo impediría el correcto manejo de la solapa lateral superior en la planta de envasado. Por todo ello, la presente invención se encuentra constituida por un procedimiento de conformación de cajas, a partir de planchas troqueladas y plegada de una determinada forma, provistas de picos vertedores, partiendo dicho procedimiento de una plancha troquelada provista de una pluralidad de hendiduras que marcan los distintos pliegues de la caja, constituyendo las cuatro caras laterales y las solapas con las que se forman el fondo y la cubierta superior. En esta plancha con la que se construye la caja, una de las solapas de la cubierta superior de la misma se encuentra prolongada por una silueta conformadora del pico vertedor, constituida por una prolongación que tras una primera banda, en la que se estrecha ligeramente por los extremos, da lugar a dos ramificaciones que finalizan en forma de un pico saliente plegado mediante una hendidura al final de la referida ramificación, a la vez que en la cara de la caja, correspondiente a la descrita prolongación de la solapa de la cubierta superior de la caja, se dispone de una ventana, coincidente con el espacio definido entre los extremos de los referidos finales de las ramificaciones, al ser plegada la prolongación de la silueta conformadora del pico vertedor, por la línea definida por la hendidura que marca el final de la solapa de la que nace la silueta conformadora del pico vertedor.- Get the figure where the double beak is always built along said line. - Achieve the maximum possible precision when superimposing the flap that forms the pouring spout on the side face of the box to which it is glued. This characteristic is of great importance, since it depends on the fact that there are no cracks in the walls of the pouring spout. - Achieve that by folding down the double side flap on the packaging floor, the third line is torn and the lower edge compensates for its shorter path, protruding a couple of mm. approximately, and thus release the tension that would otherwise prevent the correct handling of the upper side flap in the packaging plant. For all these reasons, the present invention is made up of a box-forming procedure, starting from die-cut plates and folded in a certain way, provided with pouring spouts, said procedure starting from a die-cut plate provided with a plurality of grooves that mark the different folds of the box, constituting the four lateral faces and the flaps with which the bottom and top cover are formed. In this sheet with which the box is built, one of the flaps of the top cover of the box is prolonged by a silhouette that forms the pouring spout, consisting of an extension that after a first band, in which it is slightly narrowed by the ends, gives rise to two branches that end in the form of a protruding peak folded by a slit at the end of said branch, as well as on the face of the box, corresponding to the described extension of the flap of the upper cover of the box, there is a window, coinciding with the space defined between the ends of the referred ends of the branches, when the extension of the shape of the pouring spout is folded, by the line defined by the indentation that marks the end from the flap from which the shape of the pouring spout is born.
Asimismo, el procedimiento de construcción continúa a partir de la descrita plancha troquelada mediante el repliegue de la citada silueta conformadora del pico vertedor, mediante la hendidura de separación entre esta y la solapa a partir de la que nace la referida prolongación, procediéndose a encolarse sobre la cara correspondiente de la caja, las dos ramificaciones que finalizan en forma de un pico saliente y sus respectivos finales. Por otra parte, en la etapa siguiente, en el referido procedimiento, la antes referida ventana situada en la cara de la caja, en la que se encuentra la prolongación de la solapa de la cubierta superior de la caja, se dispone de una uñeta constituida por una reborde superior marcado por una hendidura precortada, facilitando su rotura y permitiendo tirar de la pared de la ventana del pico vertedor, produciendo la rotura por la hendidura precortada de unión entre las dos ramificaciones que finalizan en forma de un pico saliente y sus respectivos finales.Likewise, the construction procedure continues from the described die-cut sheet by folding the aforementioned shape of the pouring spout, by means of the gap between it and the flap from which the aforementioned extension is born, proceeding to glue on the corresponding face of the box, the two branches that end in the shape of a projecting peak and their respective ends. On the other hand, in the following stage, in the aforementioned procedure, the aforementioned window located on the face of the box, in which the extension of the flap of the upper cover of the box is located, has a finger formed by an upper flange marked by a pre-cut groove, facilitating its breakage and allowing the window wall of the pouring spout to be pulled, causing the break by the pre-cut groove connecting the two branches that end in the form of a protruding spout and their respective endings.
Además, en la etapa siguiente, en el referido procedimiento, se completa la construcción de la caja mediante el cierre de las paredes laterales mediante el encolado de una solapa lateral y mediante el cierre inferior y superior mediante las solapas de fondo y de cubierta.Furthermore, in the following stage, in said procedure, the construction of the box is completed by closing the side walls by gluing a side flap and by closing the bottom and top by means of the bottom and cover flaps.
La presente invención incluye, además, unos perfeccionamientos que permiten mejorar el procedimiento descrito, logrando gracias a la particular forma de los elementos empleados, gancho y juego de varillas, subsanar la ocasional falta de uniformidad en el guiado de las cajas en la máquina plegadora, facilitar la apertura inicial del vertedor, así como hacer posible la realización de cajas con pico vertedor incluso cuando la solapa en la que se forma el pico vertedor es más ancha que el lomo de la caja. Por todo ello, el presente procedimiento de fabricación y caja con pico vertedor, viene a consistir en que en el proceso de conformación de la caja se cuenta con un conjunto de un gancho y un juego de varillas, del tipo "fondo automático" concebidos especialmente para esta caja, teniendo la particularidad el gancho de estar constituido por dos segmentos rígidos embutidos en un muelle, que le dota de flexibilidad, facilitando su introducción por el pasillo central incluso en aquellos casos en que el corte venga con una ligera desviación.The present invention includes, in addition, some improvements that allow improving the described procedure, achieving thanks to the particular shape of the elements used, hook and set of rods, to correct the occasional lack of uniformity in guiding the boxes in the folding machine, facilitating the initial opening of the spout, as well as making it possible to make boxes with a spout even when the flap in which the spout is formed is wider than the spine of the box. For all these reasons, the present manufacturing procedure and box with pour spout, consists of the fact that in the process of forming the box there is a set of a hook and a set of rods, of the "automatic bottom" type, specially designed for this box, having the particularity of the hook being made up of two rigid segments embedded in a spring, which gives it flexibility, facilitating its introduction through the central aisle even in those cases where the cut comes with a slight deviation.
En tal caso.-cuando la posición del gancho no coincide exactamente con el centro de la calle-, al estrecharse esta, llega un momento en el que el gancho roza con el cartón, situación en la que de utilizarse un gancho convencional se produciría normalmente la rotura del corte y por consiguiente una traba en la máquina. En nuestro caso, el gancho cede gracias al muelle y recupera la vertical al entrar de nuevo en la zona ancha, justo antes de donde tiene que enganchar.In such a case - when the hook position does not exactly coincide with the center of the street - when the street narrows, there comes a time when the hook rubs against the cardboard, a situation in which a conventional hook would normally occur the break of the cut and therefore a lock on the machine. In our case, the hook gives way thanks to the spring and recovers the vertical when entering the wide area again, just before where you have to hook.
Por otra parte, el juego de varillas anterior tiene la particularidad de que no se limita a tumbar la solapa que levanta el gancho, tal y como lo haría una varilla convencional de las que siguen al gancho de fondo automático, sino que al mismo tiempo que tumba la solapa, consigue que se levanten las orejas que constituyen las paredes laterales del pico vertedor, doblándolas noventa grados por la línea de hendido y dejándolas caer a continuación.On the other hand, the previous set of rods has the particularity that it does not limit itself to knocking down the flap that raises the hook, just as a conventional rod would do of those that follow the automatic bottom hook, but at the same time that knock down the flap, get the ears that make up the side walls of the pouring spout up, bending them ninety degrees along the crease line and then dropping them.
Esta operación tiene por objeto reblandecer el hendido de manera que se facilita la apertura inicial del pico vertedor, de modo que cuando se avanza en el montaje de la caja, del estado ilustrado en la figura 1 a la 2 de la Patente principal, no nos hemos limitado a tumbar la solapa donde se forma el pico vertedor, sino que además hemos reblandecido los hendidos para facilitar su apertura inicial. Asimismo, el anterior juego de varillas está compuesto por un elemento exterior en forma de U y de un elemento interior recto, pudiendo ser el elemento interior una chapa ancha de una sola pieza o una doble varilla, siendo su función el mantener aplastada y sujeta la parte central de la solapa donde se conforma el pico vertedor, es decir, la parte comprendida entre las líneas de hendido, una vez que esta ha sido tumbada.The purpose of this operation is to soften the crease so that the initial opening of the pour spout is facilitated, so that when progress is made in the assembly of the box, from the state illustrated in Figures 1 to 2 of the main patent, we do not We have limited to knocking down the flap where the pouring spout forms, but we have also softened the creases to facilitate their initial opening. Likewise, the previous set of rods is made up of a U-shaped outer element and a straight inner element, the inner element being able to be a wide one-piece plate or a double rod, its function being to hold down and hold the central part of the flap where the pouring spout is formed, that is, the part between the crease lines, once it has been laid down.
Además, la varilla en U tiene varias zonas, correspondiendo a distintas funciones, adopta una forma de sección circular con los extremos aplanados y en ligera forma de V, siendo su anchura mayor que la de la base de la solapa que forma el pico vertedor, de manera que dicha solapa es erguida, al ser levantada por el gancho, de manera que los extremos de la varilla en U la dejan pasar por el centro sin tocarla, hasta que la U se estrecha, roza la solapa y la tumba, de manera que en ese momento los extremos de la U ya se han situado por debajo de las orejas, continuando hacia la mitad de su longitud, donde los brazos en U dejan de discurrir paralelos al plano de la máquina y empiezan a erguirse, llegando a alcanzar su máxima altura en el fondo curvo de la U, siendo esta cota más elevada que la altura de las orejas, permitiendo que estas caigan al final del recorrido, de manera que las del pico vertedor se deslicen por encima de la varilla y sean empujadas hacia arriba, mientras la zona central continúa aplastada por la varilla central, logrando que las orejas doblen noventa grados.In addition, the U-rod has several zones, corresponding to different functions, it adopts a circular section shape with flattened ends and a slight V shape, its width being greater than that of the base of the flap that forms the pouring spout, in such a way that said flap is erect, when being lifted by the hook, so that the ends of the U-rod allow it to pass through the center without touching it, until the U narrows, brushes the flap and the grave, so that at that time the ends of the U have already been located below the ears, continuing towards the middle of its length, where the U-arms stop running parallel to the plane of the machine and begin to stand up, reaching their maximum height at the curved bottom of the U, this height being higher than the height of the ears, allowing the ears to fall at the end of the route, so that those of the pouring spout slide over the rod and are pushed upwards , while the central zone continues to be crushed by the central rod, making the ears bend 90 degrees.
Esta operación descrita de levantar las orejas tiene la ventaja de que permite doblar completamente una de ellas, girándola 180 grados respecto de la línea de hendido para la realización de cajas de lomo estrecho con pico vertedor, ya que al doblar una de las orejas no es necesario que la anchura de desarrollo de la solapa donde se conforma el pico vertedor tenga las pequeñas dimensiones del lomo de la caja. Para doblar completamente una de las orejas, basta con colocar un fleje en el punto en el que la oreja llega a su punto más alto (90 grados) y pierde contacto con la varilla de U. De esta manera, el fleje impide que la oreja inicie la caída y la va doblegando hasta tumbarla completamente.This described operation of lifting the ears has the advantage that it allows one of them to be completely folded, rotating it 180 degrees with respect to the creasing line for the production of narrow-spine boxes with pouring spout, since when folding one of the ears it is not It is necessary that the development width of the flap where the pouring spout is formed has the small dimensions of the spine of the box. To completely bend one of the ears, simply place a strap at the point where the ear reaches its highest point (90 degrees) and loses contact with the U-rod. In this way, the strap prevents the ear Start the fall and bend it until it falls completely.
Por otra parte, la solapa que forma el pico vertedor puede ser levantada por el gancho de fondo automático cuando aún se halla a cierta distancia de las puntas de las varillas largas del conjunto predoblador, situando un fleje en forma de L que impide que la solapa caiga hacia adelante tras ser soltada por el gancho. De lo contrario corremos el riesgo de que la solapa se deslice por debajo de dichas varillas, y se rompa causando además una traba importante en la máquina. Pero si el gancho levanta la solapa demasiado pronto, la solapa vuelve a caer hacia adelante tras soltarse del gancho, y en ese caso en lugar de ser empujada suavemente por el roce de las varillas exteriores, es embestida frontalmente por las varillas interiores, lo que produce roces y marcas y obliga a trabajar a menor velocidad. Por ello se requiere que la solapa llegue erguida al punto en el que el estrechamiento de las varillas la obliga a tumbarse hacia atrás. Esto puede lograrse de dos formas: Una es logrando que el gancho de fondo automático levante pronto y suelte tarde, pero esto requiere mucha sofisticación en el diseño del gancho, del muelle, y en el posicionamiento del mismo, y la otra forma es levantar pronto la solapa y mantenerla levantada durante unos centímetros, lo que se consigue de una forma sencilla situando un fleje en forma de L que impida que la solapa caiga hacia adelante tras ser soltada por el gancho.On the other hand, the flap that forms the pouring spout can be lifted by the automatic bottom hook when it is still at a certain distance from the tips of the long rods of the pre-bender assembly, placing an L-shaped strap that prevents the flap fall forward after being released by the hook. Otherwise we run the risk of the flap slipping underneath said rods, and breaking, causing a significant machine lock. But if the hook lifts the flap too soon, the flap falls forward again after being released from the hook, and in that case instead of being gently pushed by the friction of the outer rods, it is rammed frontally by the inner rods, which produces friction and marks and forces to work at a slower speed. Therefore, it is required that the flap comes upright to the point where the narrowing of the rods forces it to lie back. This can be accomplished in two ways: One is by getting the automatic bottom hook to lift early and release late, but this requires a lot of sophistication in hook and spring design and positioning, and the other way is to lift early. the flap and keep it raised for a few centimeters, which is easily achieved by placing an L-shaped strap that prevents the flap from falling forward after being released by the hook.

El presente procedimiento de fabricación y caja con pico vertedor, ilustrado en los anteriores dibujos se encuentra constituido por un procedimiento de conformación de cajas, a partir de planchas troqueladas y plegada de una determinada forma, provistas de picos vertedores, partiendo dicho procedimiento de una plancha troquelada provista de una pluralidad de hendiduras que marcan los distintos pliegues de la caja, constituyendo las cuatro caras (9, 10) laterales y las solapas con las que se forman el fondo (12) y la cubierta (15) superior. En esta plancha con la que se construye la caja, una de las solapas de la cubierta superior de la misma se encuentra prolongada por una silueta conformadora del pico vertedor, constituida por una prolongación que tras una primera banda, en la que se estrecha ligeramente por los extremos, da lugar a dos ramificaciones (7, 8) que finalizan en forma de un pico saliente (3) plegado mediante una hendidura (1) al final (5, 6) de la referida ramificación, a la vez que en la cara (9) de la caja, correspondiente a la descrita prolongación de la solapa de la cubierta superior de la caja, se dispone de una ventana (2), coincidente con el espacio definido entre los extremos de los referidos finales (5, 6) de las ramificaciones, al ser plegada la prolongación de la silueta conformadora del pico vertedor, por la línea definida por la hendidura (4) que marca el final de la solapa de la que nace la silueta conformadora del pico vertedor.The present manufacturing process and box with pouring spout, illustrated in the previous drawings, is constituted by a process for forming boxes, from die-cut plates and folded in a certain way, provided with pouring spouts, said procedure starting from a plate die-cut provided with a plurality of grooves that mark the different folds of the box, constituting the four lateral faces (9, 10) and the flaps with which the bottom (12) is formed and the upper cover (15). In this sheet with which the box is built, one of the flaps of the top cover of the box is prolonged by a silhouette that forms the pouring spout, consisting of an extension that after a first band, in which it is slightly narrowed by the ends, gives rise to two branches (7, 8) that end in the form of a projecting beak (3) folded by means of a slit (1) at the end (5, 6) of said branch, at the same time as on the face (9) of the box, corresponding to the described extension of the flap of the upper cover of the box, there is a window (2), coinciding with the space defined between the ends of the referred ends (5, 6) of the ramifications, when the extension of the shape of the pouring spout is folded, by the line defined by the slit (4) that marks the end of the flap from which the shape of the pouring spout is born.
Asimismo, el procedimiento de construcción continúa a partir de la descrita plancha troquelada mediante el repliegue de la citada silueta conformadora del pico vertedor, mediante la hendidura (4) de separación entre esta y la solapa a partir de la que nace la referida prolongación, procediéndose a encolarse sobre la cara (9) correspondiente de la caja, las dos ramificaciones (7, 8) que finalizan en forma de un pico saliente (3) y sus respectivos finales (5, 6).Likewise, the construction procedure continues from the described die-cut sheet by folding the aforementioned silhouette forming the pouring spout, by means of the separation slit (4) between it and the flap from which the said extension is born, proceeding to be glued on the corresponding face (9) of the box, the two branches (7, 8) that end in the form of a projecting spout (3) and their respective ends (5, 6).
Por otra parte, en la etapa siguiente, en el referido procedimiento, la antes referida ventana (2) situada en la cara (9) de la caja, en la que se encuentra la prolongación de la solapa de la cubierta superior de la caja, se dispone de una uñeta (14) constituida por una reborde superior marcado por una hendidura precortada, facilitando su rotura y permitiendo tirar de la pared de la ventana (2) del pico vertedor, produciendo la rotura por la hendidura (11) precortada de unión entre las dos ramificaciones (7, 8) que finalizan en forma de un pico saliente (3) y sus respectivos finales (5, 6).On the other hand, in the following stage, in the aforementioned procedure, the aforementioned window (2) located on the face (9) of the box, in which is the extension of the flap of the upper cover of the box, a tab (14) consisting of an upper flange marked by a pre-cut groove is available, facilitating its breakage and allowing the wall of the window (2) of the pouring spout to be pulled, causing the break by the pre-cut joint groove (11) between the two branches (7, 8) that end in the form of a projecting peak (3) and their respective ends (5, 6).
Además, en la etapa siguiente, en el referido procedimiento, se completa la construcción de la caja mediante el cierre de las paredes laterales (9, 10) mediante el encolado de una solapa lateral (13) y mediante el cierre inferior y superior mediante las solapas de fondo (12) y de cubierta (15). El presente procedimiento de fabricación y caja con pico vertedor, cuenta con un conjunto de un gancho y un juego de varillas, del tipo "fondo automático" concebidos especialmente para esta caja, teniendo la particularidad el gancho de estar constituido por dos segmentos rígidos embutidos en un muelle, que le dota de flexibilidad, facilitando su introducción por el pasillo central incluso en aquellos casos en que el corte venga con una ligera desviación.In addition, in the next stage, in the aforementioned procedure, the construction of the box is completed by closing the side walls (9, 10) by gluing a side flap (13) and by closing the bottom and top by means of the bottom flaps (12) and cover flaps (15). The present manufacturing procedure and box with pouring spout, has a set of a hook and a set of rods, of the "automatic bottom" type, specially designed for this box, with the particularity of the hook being made up of two rigid segments embedded in a spring, which gives it flexibility, facilitating its introduction through the central corridor even in those cases where the cut comes with a slight deviation.
En tal caso, -cuando la posición del gancho no coincide exactamente con el centro de la calle-, al estrecharse esta, llega un momento en el que el gancho roza con el cartón, situación en la que de utilizarse un gancho convencional se produciría normalmente la rotura del corte y por consiguiente una traba de la máquina. En nuestro caso, el gancho cede gracias al muelle y recupera la vertical al entrar de nuevo en la zona ancha, justo antes de donde tiene que enganchar. Por otra parte, el juego de varillas anterior tiene la particularidad de que no se limita a tumbar la solapa que levanta el gancho, tal y como lo haría una varilla convencional de las que siguen al gancho de fondo automático, sino que al mismo tiempo que tumba la solapa, consigue que se levanten las orejas que constituyen las paredes laterales del pico vertedor (3), doblándolas noventa grados por la línea de hendido (1) y dejándolas caer a continuación.In this case, -when the position of the hook does not exactly coincide with the center of the street-, when the street narrows, there comes a time when the hook rubs against the cardboard, a situation in which a conventional hook would normally be used the break of the cut and therefore a lock of the machine. In our case, the hook yields thanks to the spring and recovers the vertical when entering the wide area again, just before where it has to hook. On the other hand, the previous set of rods has the particularity that it does not limit itself to knocking down the flap that raises the hook, just as a conventional rod would do of those that follow the automatic bottom hook, but at the same time that knock down the flap, get the ears that make up the side walls of the pour spout (3) up, bending them ninety degrees along the crease line (1) and then letting them fall.
Esta operación tiene por objeto reblandecer el hendido de manera que se facilita la apertura del pico vertedor, de modo que cuando se avanza en el montaje de la caja, del estado ilustrado en la figura 1 a la 2 de la patente principal, no nos hemos limitado a tumbar la solapa donde se forma el pico vertedor, sino que además hemos reblandecido los hendidos para facilitar su apertura.The purpose of this operation is to soften the cleft in such a way as to facilitate the opening of the pouring spout, so that when progress is made in the assembly of the box, from the state illustrated in Figures 1 to 2 of the main patent, we have not limited to knocking down the flap where the pouring spout forms, we have also softened the creases to facilitate their opening.
Asimismo, el anterior juego de varillas está compuesto por un elemento exterior en forma de U y de un elemento interior recto, pudiendo ser el elemento interior una chapa ancha de una sola pieza o una doble varilla, siendo su función el mantener aplastada y sujeta la parte central de la solapa donde se conforma el pico vertedor, es decir, la parte comprendida entre las líneas de hendido (5) y (6), una vez que esta ha sido tumbada. Además, la varilla en U tiene varias zonas, correspondiendo a distintas funciones, adopta una forma de sección circular con los extremos aplanados y en ligera forma de V, siendo su anchura mayor que la de la base de la solapa que forma el pico vertedor, de manera que dicha solapa es erguida, al ser levantada por el gancho, de manera que los extremos de la varilla en U la dejan pasar por el centro sin tocarla, hasta que la U se estrecha, roza la solapa y la tumba, de manera que en ese momento los extremos de la U ya se han situado por debajo de las orejas (3), continuando hacia la mitad de su longitud, donde los brazos en U dejan de discurrir paralelos al plano de la máquina y empiezan a erguirse, llegando a alcanzar su máxima altura en el fondo curvo de la U, siendo esta cota más elevada que la altura de las orejas, permitiendo que estas caigan al final del recorrido, de manera que las del pico vertedor se deslicen por encima de la varilla y sean empujadas hacia arriba, mientras la zona central continúa aplastada por la varilla central, logrando que las orejas doblen noventa grados.Likewise, the previous set of rods is made up of a U-shaped outer element and a straight inner element, the inner element being able to be a wide one-piece plate or a double rod, its function being to hold down and hold the central part of the flap where the pouring spout is formed, that is, the part between the crease lines (5) and (6), once it has been laid down. In addition, the U-rod has several zones, corresponding to different functions, it adopts a circular section shape with flattened ends and a slight V shape, its width being greater than that of the base of the flap that forms the pouring spout, in such a way that said flap is erect, when being lifted by the hook, so that the ends of the U-rod allow it to pass through the center without touching it, until the U narrows, brushes the flap and the grave, so that at that time the ends of the U have already been located below the ears (3), continuing towards the middle of its length, where the U-arms stop running parallel to the plane of the machine and begin to stand up, reaching to reach its maximum height at the curved bottom of the U, this height being higher than the height of the ears, allowing them to fall at the end of the route, so that those of the pouring spout slide over the rod and are pushed up, while he The central zone continues to be crushed by the central rod, making the ears bend 90 degrees.
Esta operación descrita de levantar las orejas tiene la ventaja de que permite doblar completamente una de ellas, girándola 180 grados respecto de la línea de hendido (1) para la realización de cajas de lomo estrecho con pico vertedor, ya que al doblar una de las orejas no es necesario que la anchura de desarrollo de la solapa donde se conforma el pico vertedor tenga las pequeñas dimensiones del lomo de la caja. Para doblar completamente una de las orejas, basta con colocar un fleje en el punto en el que la oreja llega a su punto más alto (90 grados) y pierde contacto con la varilla de U. De esta manera, el fleje impide que la oreja inicie la caída y la va doblegando hasta tumbarla completamente.This described operation of lifting the ears has the advantage that it allows one of them to be completely bent, turning it 180 degrees with respect to the crease line (1) for the production of narrow-spine boxes with pouring spout, since when folding one of the ears it is not necessary that the development width of the flap where the pouring spout is formed has the small dimensions of the spine of the box. To completely bend one of the ears, simply place a strap at the point where the ear reaches its highest point (90 degrees) and loses contact with the U-rod. In this way, the strap prevents the ear Start the fall and bend it until it falls completely.
Por otra parte, la solapa que forma el pico vertedor puede ser levantada por el gancho de fondo automático cuando aún se halla a cierta distancia de las puntas de las varillas largas del conjunto predoblador, situando un fleje en forma de L que impide que la solapa caiga hacia adelante tras ser soltada por el gancho.On the other hand, the flap that forms the pouring spout can be lifted by the automatic bottom hook when it is still at a certain distance from the tips of the long rods of the pre-bender assembly, placing an L-shaped strap that prevents the flap fall forward after being released by the hook.
Finalmente, la forma, materiales y dimensiones podrán ser variables y en general, todo cuanto sea accesorio y secundario, siempre que no altere cambie o modifique la esencialidad de los perfeccionamientos que se han descrito. Finally, the shape, materials and dimensions may be variable and in general, everything that is accessory and secondary, as long as it does not alter change or modify the essentiality of the improvements that have been described.
