Maquina sacabocados de dos esquinas.Two corner punch machine.
5 Campo tecnico5 Technical field
[0001] La presente invencion pertenece al sector de las maquinas de trabajo con papel y especificamente al sector de las maquinas especializadas en el corte del papel utilizado para revestir cajas para embalajes valiosos.[0001] The present invention belongs to the sector of paper work machines and specifically to the sector of machines specialized in cutting paper used to coat boxes for valuable packaging.
10 Tecnica anterior10 Prior art
[0002] Las cajas utilizadas para contener productos de valor, por ejemplo articulos de cuero, zapatos de lujo, perfumes, o similares, se hacen a menudo de carton revestido con papel fino. Mientras que el carton proporciona la robustez necesaria, el revestimiento de papel se utiliza para enriquecer la apariencia de la caja y de su cubierta[0002] The boxes used to contain valuable products, for example leather goods, fancy shoes, perfumes, or the like, are often made of cardboard coated with thin paper. While the cardboard provides the necessary robustness, the paper lining is used to enrich the appearance of the box and its cover
15 respectiva. El revestimiento de papel se coloca en una caja de carton ya formada, por lo tanto, para que el papel se adhiera bien al sustrato, es necesario que se forme adecuadamente, teniendo en cuenta las dimensiones de la caja a revestir, asi como de la solapa requerida. En el caso de una caja que tiene la forma de un paralelepipedo regular, el papel conformado adquiere substancialmente la forma de una cruz en la que los brazos opuestos son identicos dos por dos; todos los brazos sobresalen en una longitud igual a la suma de la altura de la caja a revestir mas la 20 solapa interna.15 respectively. The paper lining is placed in an already formed cardboard box, therefore, in order for the paper to adhere well to the substrate, it is necessary that it be properly formed, taking into account the dimensions of the box to be coated, as well as the required flap. In the case of a box that has the shape of a regular parallelepiped, the shaped paper substantially acquires the shape of a cross in which the opposite arms are identical two by two; all the arms protrude in a length equal to the sum of the height of the box to be covered plus the 20 internal flap.
[0003] Tipicamente, dos brazos tienen una anchura igual a la longitud de dos lados de la caja, mientras que los dos brazos restantes son mas anchos, ya que incorporan las solapas utilizadas para revestir los bordes de la caja.[0003] Typically, two arms have a width equal to the length of two sides of the box, while the remaining two arms are wider, since they incorporate the flaps used to line the edges of the box.
25 [0004] Mas especificamente, la forma de cruz se completa con una serie de cortes que tienen la forma de una semi "V" en cada punto donde los brazos se cruzan entre si. El proposito de este corte es hacer posible doblar las solapas laterales sin causar arrugas.[0004] More specifically, the cross shape is completed with a series of cuts that have the shape of a semi "V" at each point where the arms cross each other. The purpose of this cut is to make it possible to fold the side flaps without causing wrinkles.
[0005] Se conocen dos soluciones tecnicas principales desde hace mucho tiempo en este sector para conformar el 30 papel.[0005] Two major technical solutions have been known for a long time in this sector for shaping paper.
[0006] La primera solucion se basa en el uso de un punzon sacabocados plano dedicado, en el que una pluralidad de cuchillas metalicas sostenidas por un soporte plano, tipicamente de madera, duplica el perimetro exacto del papel a obtener. La segunda solucion se basa en el uso de una maquina herramienta especial, denominada maquina de[0006] The first solution is based on the use of a dedicated flat punch punch, in which a plurality of metal blades supported by a flat support, typically made of wood, doubles the exact perimeter of the paper to be obtained. The second solution is based on the use of a special machine tool, called a machine
35 perforacion, estando esta ultima normalmente equipada con dos dispositivos de perforacion ajustables, montados sobre una traviesa movil capaz de moverse hacia abajo y hacia arriba. En correspondencia con cada movimiento descendente de la traviesa movil, los dispositivos de perforacion conforman simultaneamente dos de las cuatro esquinas de la pila de hojas de papel.35 drilling, the latter being normally equipped with two adjustable drilling devices, mounted on a mobile crossbeam capable of moving down and up. Corresponding to each downward movement of the mobile sleeper, the piercing devices simultaneously make up two of the four corners of the stack of paper sheets.
40 [0007] En las maquinas de perforacion, cada esquina de la hoja se elimina gracias a la accion de un dispositivo de perforacion; este ultimo soporta una accion combinada de dos cuchillas, denominadas cuchilla frontal y cuchilla lateral, que cooperan con una contracuchilla frontal y una contracuchilla lateral respectivamente. La cuchilla frontal y la cuchilla lateral forman un angulo sustancialmente recto en el plano.40 [0007] In drilling machines, each corner of the blade is eliminated thanks to the action of a drilling device; The latter supports a combined action of two blades, called front blade and side blade, which cooperate with a front counter knife and a side counter knife respectively. The front blade and the side blade form a substantially straight angle in the plane.
45 [0008] Las posiciones de las cuchillas y de las contracuchillas en el plano de corte son ajustables, de manera que una maquina es capaz de preparar revestimientos de papel adecuados para diferentes cajas.[0008] The positions of the blades and counter blades in the cutting plane are adjustable, so that a machine is capable of preparing suitable paper liners for different boxes.
[0009] Con el fin de perforar completamente una pila de hojas, son necesarias dos operaciones de corte, de hecho, despues de la primera operacion de corte, para completar la muesca de todas las hojas, es necesario retirar 50 la pila parcialmente perforada, girarla 180 grados y luego volver a insertarla en la maquina para un posterior movimiento hacia abajo de la traviesa movil que realiza las dos ultimas muescas. Ambos dispositivos de perforacion se mueven simultaneamente y cada dispositivo comprende una cuchilla frontal y una cuchilla lateral; ambas cuchillas ejercen su accion de corte cooperando con sus respectivas contracuchillas fijas, frontal y lateral.[0009] In order to completely pierce a stack of sheets, two cutting operations are necessary, in fact, after the first cutting operation, to complete the notch of all the sheets, it is necessary to remove the partially perforated stack, turn it 180 degrees and then reinsert it into the machine for a subsequent downward movement of the mobile crossbar that makes the last two notches. Both drilling devices move simultaneously and each device comprises a front blade and a side blade; both blades exert their cutting action cooperating with their respective fixed, front and side counter knives.
55 [0010] Vale la pena senalar que ambas soluciones mencionadas anteriormente presentan algunos inconvenientes.55 [0010] It is worth noting that both solutions mentioned above have some drawbacks.
[0011] El uso de un punzon sacabocados plano es muy costoso en el caso de que se corten laminas para cajas de diferentes dimensiones, ya que cada geometria de corte requiere la construccion de un punzon sacabocados especifico. Por otra parte, el uso de un punzon sacabocados permite obtener unos perimetros de corte muy[0011] The use of a flat punch punch is very expensive in the case that sheets are cut for boxes of different dimensions, since each cutting geometry requires the construction of a specific punch punch. On the other hand, the use of a punch punch allows to obtain a few cutting perimeters
precisos, con las denominadas muescas de dos esquinas, es decir, muescas con un pequeno corte angular en correspondencia con cada una de las esquinas de la caja a revestir, para evitar que la solapa se solape internamente en cada borde. En la presente descripcion, este corte se denominara corte secundario o muesca secundaria y el conjunto de corte que lo realiza se denominara conjunto de corte secundario o conjunto de corte a 5 presion, mientras que el conjunto utilizado para realizar una de las dos muescas principal o primaria se denominara conjunto de corte principal, o primario.precise, with the so-called two-corner notches, that is, notches with a small angular cut in correspondence with each of the corners of the box to be coated, to prevent the flap from overlapping internally at each edge. In the present description, this cut will be called a secondary cut or secondary notch and the cut assembly that performs it will be called a secondary cut set or 5-pressure cut set, while the set used to make one of the two main notches or primary shall be called the primary or primary cut set.
[0012] Otra ventaja de un corte obtenido por medio de un punzon sacabocados plano consiste en la posibilidad de conformar el perimetro de corte de tal manera que tenga en cuenta el espesor del carton utilizado para fabricar la[0012] Another advantage of a cut obtained by means of a flat punch punch consists in the possibility of forming the cutting perimeter in such a way that it takes into account the thickness of the cardboard used to manufacture the
10 caja a revestir.10 box to be coated.
[0013] Este efecto se consigue modificando el corte en forma de semi "V" en un corte asimetrico en forma de "V".[0013] This effect is achieved by modifying the semi-shaped "V" cut in an asymmetrical "V" shaped cut.
[0014] En las maquinas de pertoracion, para tener en cuenta el espesor del carton, se obtiene el efecto de corte 15 asimetrico en forma de "V" gracias a una ligera inclinacion de las cuchillas laterales con respecto a las duchillas[0014] In the machines of pertoracion, to take into account the thickness of the cardboard, the effect of asymmetric cutting in the form of "V" is obtained thanks to a slight inclination of the lateral blades with respect to the showers
frontales, para formar un angulo entre si ligeramente mayor que un angulo recto. Sin embargo, esta solucion evita que el borde del papel de revestimiento este pertectamente paralelo al borde de la caja, lo que da como resultado un aspecto final desagradable.frontal, to form an angle to each other slightly greater than a right angle. However, this solution prevents the edge of the coating paper from being parallel to the edge of the box, which results in an unpleasant final appearance.

[0019] Los conjuntos de corte a presion (8) se montan en dispositivos de un tipo conocido que permiten ajustar su posicion con respecto a la superficie de trabajo de la maquina, para poder determinar la posicion en la que realizar la muesca secundaria con precision.[0019] The pressure cutting assemblies (8) are mounted on devices of a known type that allow to adjust their position with respect to the working surface of the machine, in order to determine the position in which to make the secondary notch accurately .
45Four. Five
[0020] De acuerdo con una realizacion de esta invencion, el conjunto de corte secundario se dispone de tal manera que el portacuchillas (6) es capaz de retroceder un poco dentro del bloque, ganando la accion de contraste ejercida por un medio elastico de compresion apropiado (4).[0020] According to an embodiment of this invention, the secondary cutting assembly is arranged in such a way that the knife holder (6) is able to retract a little inside the block, gaining the contrast action exerted by an elastic compression means. appropriate (4).
50 [0021] El bloque de fijacion superior esta montado en la traviesa movil de la maquina de pertoracion, que acciona el movimiento vertical alternativo de los conjuntos de corte principales.[0021] The upper fixing block is mounted on the mobile crossbar of the delivery machine, which drives the alternative vertical movement of the main cutting assemblies.
[0022] La accion de corte realizada por la segunda muesca tiene lugar debido al movimiento descendente del conjunto de corte (8) hasta que la cuchilla angular (3) comienza a cortar la pila de hojas a pertorar, despues el[0022] The cutting action performed by the second notch takes place due to the downward movement of the cutting assembly (8) until the angular blade (3) begins to cut the stack of sheets to be delivered, after the
55 movimiento descendente continua hasta que la cuchilla (3) alcanza la base de la pila de hojas, comprimiendo de esta manera los medios elasticos (4); de esta manera el conjunto de corte a presion es capaz de tambien perforar las hojas que estan situadas en el fondo de la pila.55 continuous downward movement until the blade (3) reaches the base of the stack of sheets, thereby compressing the elastic means (4); in this way the pressure cutting assembly is also able to pierce the sheets that are located at the bottom of the stack.
[0023] Es necesario senalar que el conjunto de corte a presion es solo una de las posibles realizaciones de la[0023] It is necessary to point out that the pressure cutting assembly is only one of the possible embodiments of the
presente invencion, de hecho se podria obtener un efecto similar utilizando conjuntos de corte que no esten dotados de elementos elasticos de compresion y donde el movimiento descendente de la herramienta de corte angular se acciona por un sistema de presion de aceite o sistema neumatico o por otro dispositivo conocido.In the present invention, in fact a similar effect could be obtained using cutting assemblies that are not provided with elastic compression elements and where the downward movement of the angular cutting tool is driven by an oil pressure system or pneumatic system or by another known device.
5 [0024] Existen dos posibles alternativas: de acuerdo con una solucion tecnica anterior, el conjunto de corte secundario esta montado en la traviesa movil y esta dotado de medios independientes para hacer que la cuchilla y el portacuchillas bajen con respecto al soporte superior conectado a dicha traviesa movil; de acuerdo con una segunda solucion, el conjunto de corte secundario puede ser independiente de la traviesa movil, pero en cualquier caso debe estar dotado de medios independientes para hacer que la cuchilla descienda y realice la muesca secundaria.[0024] There are two possible alternatives: according to a prior technical solution, the secondary cutting assembly is mounted on the mobile crossbar and is provided with independent means to make the blade and the knife holder lower with respect to the upper support connected to said naughty mobile; According to a second solution, the secondary cutting assembly can be independent of the mobile crossbar, but in any case it must be provided with independent means to cause the blade to descend and make the secondary notch.
