OBJETO DE LA INVENCIONOBJECT OF THE INVENTION
Es objeto de la presente invencion, tal y como el trtulo establece, una maquina para cortar laminas de pizarra con formato rectangular realizado con un escuadre optimo de manera que sus cuatro lados formen angulos rectos entre s^ y donde el mdice de roturas claramente se ha reducido frente a otras maquinas del estado de la tecnica.It is the object of the present invention, as the title establishes, a machine for cutting slate sheets with rectangular format made with an optimal square so that its four sides form right angles to each other and where the index of tears has clearly been reduced compared to other machines of the state of the art.
Caracteriza a la presente maquina los elementos que la forman, sus caracteristicas constructivas y la forma de actuar de los mismos de manera se lleva a cabo un segundo corte o corte transversal con la lamina de pizarra inmovilizada mejorando el resultado final en cuanto a perpendicularidad de los lados entre si, gracias tambien al empleo de un sistema de guiado rigido para el corte transversal.The present machine characterizes the elements that form it, its construction characteristics and the way they act in such a way, a second cross-section or cut is carried out with the immobilized slate sheet improving the final result in terms of perpendicularity of the sides to each other, thanks also to the use of a rigid guidance system for cross-cutting.
Por lo tanto, la presente invencion se circunscribe dentro del ambito de las maquinas empleadas para cortar laminas de materiales de pizarra o similares.Therefore, the present invention is limited within the scope of the machines used to cut sheets of slate materials or the like.
ANTECEDENTES DE LA INVENCIONBACKGROUND OF THE INVENTION
En el estado de la tecnica son conocidas maquinas cortadoras de pizarra en formato rectangular, como las descritas en los registros ES-U-1040702 y ES-2289968, si bien cumplen con la finalidad buscada, no estan exentas de contar con aspectos susceptibles de ser mejorados.In the state of the art slate cutting machines are known in rectangular format, such as those described in registers ES-U-1040702 and ES-2289968, although they fulfill the intended purpose, they are not exempt from having aspects that can be improved
El proceso de corte transversal o segundo corte descrito en dichas patentes esta basado en el arrastre solidario de la pizarra por bandas o cadenas, haciendo estas de guia y avance de la pizarra durante el corte de la misma, es decir, existe un elemento motriz de avance solidario a la pizarra durante el corte.The cross-cutting process or second cut described in said patents is based on the solidarity drag of the slate by bands or chains, making these guides and advancing the slate during the cutting of the slate, that is, there is a motive element of Solidarity advance to the board during the cut.
Estos sistemas tienen el problema de que el resultado del corte de los bordes de la pizarra, es el inducido por la direccion de avance de tales medios (cadenas y bandas) elasticos y flexibles, que a menudo estan desgastados, torsionados y desalineados por la influencia deThese systems have the problem that the result of cutting the edges of the slate is that induced by the direction of advance of such elastic and flexible means (chains and bands), which are often worn, twisted and misaligned by the influence from

la pizarra,que es un material altamente abrasivo. Debido a estas causas, se produce el efecto de que los bordes de la pieza procesada resulten con imperfecciones en el paralelismo de los bordes, que deberian ser perfectamente paralelos y el escuadre de los bordes que tendrian que ser ortogonales. Este efecto se ha querido resolver por el apriete de rodillos que cinen la lamina de pizarra a tales medios de arrastre durante el corte acentuando los efectos negativos en muchos casos y con efecto colateral de la rotura de las finas y fragiles laminas de pizarra.the slate, which is a highly abrasive material. Due to these causes, there is an effect that the edges of the processed piece result in imperfections in the parallelism of the edges, which should be perfectly parallel and the square of the edges that should be orthogonal. This effect has been resolved by the tightening of rollers that cincate the slate sheet to such means of drag during the cut, accentuating the negative effects in many cases and with collateral effect of the breakage of the thin and fragile slate sheets.
Tambien ocurre que en algunos casos la lamina de pizarra en bruto esta muy sobredimensionada con respecto a la medida de acabado pretendida, y por lo tanto, sobresale del medio de arrastre una masa importante de la pizarra, que combinado con las altas velocidades de los medios de arrastre durante el corte, provoca fuerzas de inercia considerables que producen tambien los ya mencionados efectos indeseables. Para solucionar esto, se ha aumentado el apriete de los rodillos, aumentando tambien el porcentaje de roturas de las pizarras con la consiguiente perdida de material y produciendose tambien atascos en tales maquinas.It also happens that in some cases the raw slate sheet is very oversized with respect to the intended finish measure, and therefore, an important mass of the slate protrudes from the drag means, which combined with the high media speeds of drag during the cut, causes considerable inertia forces that also produce the aforementioned undesirable effects. In order to solve this, the tightening of the rollers has been increased, also increasing the percentage of slab breaks with the consequent loss of material and also causing jams in such machines.
Por lo tanto, es objeto de la presente invencion superar los inconvenientes apuntados derivados del avance de la pizarra durante el corte mediante cadenas o bandas relativos al descuadre de los lados perpendiculares y a la rotura las laminas bien por exceso de presion o por fragilidad de las laminas, desarrollando una maquina como la que a continuacion se describe y queda recogida en su esencialidad en la reivindicacion primera.Therefore, it is the object of the present invention to overcome the aforementioned drawbacks arising from the advance of the slate during the cutting by means of chains or bands related to the perpendicular sides and to the breakage of the sheets either due to excess pressure or fragility of the sheets , developing a machine like the one described below and is included in its essentiality in the first claim.

La lamina de pizarra (20) es entonces succionada de esta posicion por el segundo grupo de ventosas (4) avanzandola de forma lineal hacia la banda (8) de primer corte de la maquina, donde es depositada.- a slate sheet feeder mounted on the machine structure and comprising two perpendicular linear guides (1) and (2) each provided with supports for suction cups groups (3) and (4) respectively, said groups being (3) and (4) both actuated synchronously by a double crank crank system (5), so that the first group of suction cups (3) sucks a slate (20) from a stack (6) of slates and deposits it in a roller path (7) with advance perpendicular to the direction of advance of a band (8) of the first cut of the machine until it stops in a guide (9) parallel to the direction of advance of said band (8). The slate sheet (20) is then suctioned out of this position by the second group of suction cups (4) advancing it in a linear fashion towards the first cutting strip (8) of the machine, where it is deposited.
- una zona de corte longitudinal o primer corte, que comprende una banda (8) que arrastra a la lamina de pizarra llegada del alimentador hacia el corte paralelo proporcionado por dos motores con sendas fresas o discos de corte. En este modulo se le proporciona a los bordes longitudinales de la pizarra un corte paralelo inducido por el avance de la banda solidaria a la pizarra que la transporta hasta que esta lamina de pizarra (21) incide por uno de los bordes no cortados en el tope de gma (10) enfrentado a dicha banda y que es regulable automaticamente en funcion de de la medida de corte seleccionada.- a longitudinal cutting area or first cut, comprising a band (8) that draws the slate sheet from the feeder towards the parallel cut provided by two motors with two milling cutters or cutting discs.

- dos topes empujadores (13) con posicion de principio y final de carrera segun el eje Z,- two pusher stops (13) with position of beginning and end of stroke according to the Z axis,
- dos motores (14) con fresas o discos de corte (15) y- two motors (14) with cutters or cutting discs (15) and
- dos topes extractores (16) con posicion de principio y final de carrera segun el eje Z, para la extraccion de la pizarra (22) que ya ha sido cortada.- two extractor stops (16) with position of beginning and end of stroke according to the Z axis, for the extraction of the board (22) that has already been cut.
Cuando llega una pizarra (21) al tope de gma (10) enfrentado a la banda del primer corte (8) los topes empujadores (13) avanzan la lamina de pizarra (21) empujandola por uno de los bordes ya cortados hasta la posicion del segundo corte de esta, que coincide con la posicion de final de carrera del modulo de corte transversal(12), despues el modulo de corte transversal (12) retrocede hacia principio de carrera quedando la pizarra (21) en aquella posicion inmovilizada por unos elementos de pison (17).When a slate (21) arrives at the gma stop (10) facing the band of the first cut (8) the pusher stops (13) advance the slate sheet (21) pushing it along one of the already cut edges to the position of the second cut of this, which coincides with the end-of-stroke position of the cross-sectional module (12), then the cross-sectional module (12) goes back towards the beginning of the stroke, leaving the board (21) in that position immobilized by elements of pison (17).
En este retroceso que es solidario para los tres elementos que forman el modulo (topes empujadores (13), motores de corte (14) y topes extractores (16)) se producen los siguientes movimientos en los elementos que lo conforman:In this setback that is integral to the three elements that make up the module (pusher stops (13), cutting motors (14) and extractor stops (16)) the following movements occur in the elements that make it up:
o los topes empujadores (13) se elevan para no interferir con la pizarra (21) que esta llegando al tope de gma (10) procedente de la banda del primer corte (8).or the pusher stops (13) are raised so as not to interfere with the board (21) that is reaching the gma stop (10) coming from the band of the first cut (8).
o los motores de corte (14) en su retroceso cortan los dos bordes ortogonales a los del primer corte.or the cutting motors (14) in their recoil cut the two orthogonal edges to those of the first cut.
o los topes extractores (16) descienden para no interferir con la lamina de pizarra (22) posicionada en el lugar de corte ortogonal o segundo corte o corte transversal.or the extractor stops (16) descend so as not to interfere with the slate sheet (22) positioned at the place of orthogonal cut or second cut or cross section.

Asi, dicha perpendicularidad con respecto a los cortes longitudinales y paralelismo de ambos bordes procesados en este modulo de corte transversal, vienen definidos por el guiado (11) rigido y estable soporte del modulo de corte transversal (12) y no por la calidad de la tension, rectitud y alineacion de una banda o de una cadena que son elementos flexibles. Del mismo modo, al permanecer la pizarra estatica durante el corte, se elimina las fuerzas de inercia provocadas por la aceleracion de esta.Thus, said perpendicularity with respect to the longitudinal cuts and parallelism of both edges processed in this cross-sectional module, are defined by the rigid and stable guidance (11) of the cross-sectional module (12) and not by the quality of the tension, straightness and alignment of a band or chain that are flexible elements. In the same way, when the static slate remains during the cut, the inertia forces caused by its acceleration are eliminated.
Aprovechando que las laminas de pizarra permanecen inmoviles, opcionalmente, es posible realizar un punzonado o taladrado de las pizarras, mediante unos medios de punzonado o taladrado superiores dispuestos en la zona donde se inmoviliza la lamina para realizar el corte transversal o segundo corte, y que incidiran sobre la cara superior de la pizarra, aprovechando que esta se encuentra parada durante el cortado; esto en las maquinas cuya pizarra avanza durante el cortado, no es posible.Taking advantage of the fact that the slate sheets remain immobile, optionally, it is possible to perform a punching or drilling of the slates, by means of superior punching or drilling means arranged in the area where the laminate is immobilized to perform the transverse or second cut, and that they will affect the upper side of the board, taking advantage of the fact that it is stopped during cutting; this in the machines whose slate advances during cutting, is not possible.
En el modulo transversal, los motores de corte (14) estan montados en soportes individuales (18), dotados de un guiado ortogonal a la direccion de avance de corte para mediante una combination de cilindros neumaticos de diferentes carreras (19), poder regular las dimensiones de corte mediante la selection de un operario.In the cross-sectional module, the cutting motors (14) are mounted on individual supports (18), equipped with an orthogonal guidance to the direction of cutting progress, by means of a combination of pneumatic cylinders of different races (19), to be able to regulate the cutting dimensions by selecting an operator.
Descrita suficientemente la naturaleza de la presente invention, asi como la manera de ponerla en practica, se hace constar que, dentro de su esencialidad, podra ser llevada a la practica en otras formas de realization que difieran en detalle de la indicada a trtulo de ejemplo, y a las cuales alcanzara igualmente la protection que se recaba, siempre que no altere, cambie o modifique su principio fundamental.Describing sufficiently the nature of the present invention, as well as the way of putting it into practice, it is noted that, within its essentiality, it may be carried out in other forms of realization that differ in detail from that indicated by way of example. , and which will also achieve the protection sought, provided that it does not alter, change or modify its fundamental principle.
