La invencion consiste en una maquina de lijado de superficies cerradas, segun las reivindicaciones.The invention consists of a sanding machine for closed surfaces, according to the claims.
Esta ideada para piezas concavas (para poder introducir el tope que se indicara mas adelante) y con una superficie continua que posee una llnea generatriz. Es decir, cuando la pieza este apoyada en una mesa horizontal, con una concavidad hacia abajo, la superficie mas exterior sera identica en cualquier direccion. Es decir, la superficie esta formada por el movimiento de la llnea generatriz por el perlmetro de una de las bases.It is designed for concave pieces (to be able to introduce the stop indicated below) and with a continuous surface that has a generating line. That is, when the piece is supported on a horizontal table, with a concavity down, the outermost surface will be identical in any direction. That is, the surface is formed by the movement of the generating line by the perimeter of one of the bases.
Asl, la maquina es del tipo que comprende una banda continua de material rugoso, o lija, que se mueve entre al menos dos rodillos, al menos uno de ellos un rodillo motor. Ademas los rodillos estan dispuestos con su eje vertical, y comprenden al menos un rodillo de molde, cuya superficie forma el negativo de la llnea generatriz de la pieza. El rodillo de molde sera preferiblemente desmontable para trabajar con diferentes formas de la pieza.Thus, the machine is of the type comprising a continuous band of rough material, or sandpaper, that moves between at least two rollers, at least one of them a motor roller. In addition, the rollers are arranged with their vertical axis, and comprise at least one mold roller, whose surface forms the negative of the generating line of the piece. The mold roller will preferably be removable to work with different shapes of the piece.
El rodillo de molde esta situado proximo a una mesa horizontal, de apoyo de la pieza. En la mesa se dispone un tope movil contra cada uno de los rodillos de molde. El tope esta, respecto del rodillo de molde, al otro lado del lado rugoso de la banda continua. El tope posee un elemento de rodadura perimetral de eje vertical, preferiblemente motorizado para girar en direccion concordante con el rodillo de molde. Es decir, dado que entre los dos se situa la banda continua, deben girar en direcciones opuestas.The mold roller is located next to a horizontal table, supporting the piece. On the table there is a movable stop against each of the mold rollers. The stop is, with respect to the mold roller, on the other side of the rough side of the continuous web. The stop has a vertical axis perimeter rolling element, preferably motorized to rotate in a direction consistent with the mold roller. That is, since the continuous band is placed between the two, they must turn in opposite directions.
El tope puede ser movil contra el rodillo de molde correspondiente por medio de un resorte, y preferiblemente se podra retirar automaticamente cuando el operario lo comande.The stop can be movable against the corresponding mold roller by means of a spring, and preferably it can be automatically removed when the operator commands it.
En una realizacion preferida, la banda continua es oscilante en direccion vertical.In a preferred embodiment, the continuous band is oscillating in the vertical direction.
En una realizacion mas preferida, la maquina posee un aspirador proximo a cada rodillo de molde, aguas abajo de este en el sentido de avance de la banda continua, y preferiblemente asociado a un cepillo.In a more preferred embodiment, the machine has a vacuum cleaner close to each mold roller, downstream of it in the direction of advance of the continuous web, and preferably associated with a brush.

MODOS DE REALIZACION DE LA INVENCIONEMBODIMENTS OF THE INVENTION
A continuation se pasa a describir de manera breve un modo de realization de la invencion, como ejemplo ilustrativo y no limitativo de esta.Next, a mode of realization of the invention is briefly described as an illustrative and non-limiting example of this.
La maquina que se representa en la figura 1 consta de una banda continua (1) de material rugoso, dispuesta en una serie de rodillos (2,3,4) verticales. Los rodillos (2,3,4) se dividen en tres tipos: al menos un rodillo motor (2), que mueve la banda continua (1), rodillos directores (3), que le dan forma, y rodillos de molde (4), normalmente uno por maquina, que empujan la banda continua (1) contra la pieza (5) trabajada. Los rodillos motores (2) pueden tambien dar forma al recorrido de la banda continua (1).The machine shown in Figure 1 consists of a continuous band (1) of rough material, arranged in a series of vertical rollers (2,3,4). The rollers (2,3,4) are divided into three types: at least one motor roller (2), which moves the continuous band (1), director rollers (3), which shape it, and mold rollers (4 ), usually one per machine, which pushes the continuous band (1) against the workpiece (5). The drive rollers (2) can also shape the path of the continuous web (1).
Un tope (6) vertical esta dispuesto enfrentado a cada rodillo de molde (4), de forma que apriete contra el cualquier pieza (5) colocada entre ambos (figura 3). El tope (6) esta montado en un resorte (7) para realizar el apriete, u otro mecanismo similar, cuya fuerza regulara la profundidad del lijado. El tope (6) consistira en un elemento de rodadura para permitir el movimiento relativo entre la pieza (5) y el tope (6). Puede estar motorizado, con una velocidad de giro coordinada con la de la banda continua (1), para ayudar al movimiento de la pieza (5). Por ejemplo, puede ser un poco mas lento, en velocidad lineal, que la banda continua (1) para asegurar que la pieza (5) es frenada por el tope (6) y se produce el lijado.A vertical stop (6) is arranged facing each mold roller (4), so that it presses against any part (5) placed between them (Figure 3). The stop (6) is mounted on a spring (7) to perform the tightening, or other similar mechanism, whose force will regulate the depth of the sanding. The stop (6) will consist of a rolling element to allow relative movement between the piece (5) and the stop (6). It can be motorized, with a speed of rotation coordinated with that of the continuous band (1), to help the movement of the piece (5). For example, it may be a little slower, in linear speed, than the continuous band (1) to ensure that the part (5) is braked by the stop (6) and sanding occurs.

El tope (6) esta dispuesto en una gula (8) realizada en una mesa (9) de apoyo de la pieza a trabajar (5). Las dimensiones de la mesa (9) dependera del tamano previsto para las piezas (5), que deben poder deslizar y mantenerse sobre esta independientemente de su posicion (figura 2).The stop (6) is arranged in a glutton (8) made on a table (9) supporting the workpiece (5). The dimensions of the table (9) will depend on the size provided for the pieces (5), which should be able to slide and remain on it regardless of their position (figure 2).
El ejemplo de rodillo de molde (4) se aprecia especialmente en la figura 3. Posee una serie de salientes y recovecos que forman el negativo de la superficie a trabajar de la pieza (5) (de la llnea generatriz citada anteriormente). El rodillo de molde (4) sera desmontable para sustituirlo por otro mas adecuado cuando cambie el perfil de la pieza (5). Si se desea puede estar motorizado, aunque igualmente puede girar por el movimiento de la banda continua (1).The example of a mold roller (4) can be seen especially in Figure 3. It has a series of projections and recesses that form the negative of the work surface of the piece (5) (of the generator line mentioned above). The mold roller (4) will be removable to replace it with a more suitable one when changing the profile of the piece (5). If desired, it can be motorized, although it can also be rotated by the movement of the continuous band (1).
Preferiblemente la banda continua (1) va realizando un movimiento oscilante arriba-abajo. Para ello, el rodillo motor (2), o alguno de los rodillos directores (3) sera movil en esa direccion, provocando el deslizamiento de la banda continua (1) hacia arriba y hacia abajo. De esta forma, el desgaste del material rugoso de la banda continua (1) es mas homogeneo y se reduce la necesidad de sustituirlo.Preferably the continuous band (1) is performing an up-down oscillating movement. For this, the motor roller (2), or any of the director rollers (3) will be mobile in that direction, causing the continuous band (1) to slide up and down. In this way, the wear of the rough material of the continuous web (1) is more homogeneous and the need to replace it is reduced.
Los demas rodillos (2,3,4) pueden tener una barrera en los bordes de la zona util para evitar que la banda continua (1) pueda salirse de la misma. Igualmente, es preferible poner algun sistema tensor de la banda continua (1) en alguno de los rodillos (2,3,4) o externo a estos. El sistema tensor estara por el lado interior de la banda continua (1) para que el material rugoso no le afecte. En una segunda solucion, un sensor (infrarrojo, por contacto) detecta cuando la banda continua (1) esta proxima a un borde para cambiar el sentido del movimiento oscilante.The other rollers (2,3,4) may have a barrier at the edges of the useful area to prevent the continuous band (1) from leaving it. Likewise, it is preferable to place some tensioning system of the continuous band (1) on one of the rollers (2,3,4) or external to them. The tensioning system will be on the inside of the continuous band (1) so that the rough material does not affect it. In a second solution, a sensor (infrared, by contact) detects when the continuous band (1) is close to an edge to change the direction of the oscillating movement.
En la figura 2 se aprecian las diferentes etapas en el lijado de una pieza (5) con una superficie lateral cerrada. El movimiento de la banda continua (1) va lijando la zona de la pieza (5) entre el tope (6) y el rodillo de molde (4), y a su vez provoca el giro de la pieza (5) que es arrastrado por la banda continua (1). Los vertices de la superficie a tratar de la pieza (5) seran preferiblemente curvos o "matados”. En caso contrario se atascarla en esos vertices, aunque si el tope (6) esta motorizado y desliza facilmente en su gula (8), podrla salir de esos atascos.Figure 2 shows the different stages in sanding a piece (5) with a closed side surface. The movement of the continuous band (1) is sanding the area of the piece (5) between the stop (6) and the mold roller (4), and in turn causes the rotation of the piece (5) that is dragged by the band continues (1). The vertices of the surface to be treated of the piece (5) will preferably be curved or “killed.” Otherwise it will get stuck in those vertices, although if the stop (6) is motorized and easily slides in its glutton (8), it could Get out of those jams.
Es recomendable situar un aspirador (10) proximo al punto de lijado. Este aspirador tomara el polvo o serrln generado para su almacenamiento. Si se desea, puede estar asociado a un cepillo (no representado), fijo o movil, que ayude a separar el polvo o serrln de la pieza (5).It is advisable to place a vacuum cleaner (10) near the sanding point. This vacuum will take the dust or sawdust generated for storage. If desired, it can be associated with a brush (not shown), fixed or mobile, which helps to separate the dust or sawdust from the piece (5).
Los rodillos motores (2) y cualquier otro elemento activo estara conectado a un motor, generalmente electrico, conectado a una fuente de energla adecuada: red electrica, generador,... sin que sea relevante para la invencion.The motor rollers (2) and any other active element will be connected to a motor, generally electric, connected to a suitable source of energy: electrical network, generator, ... without it being relevant for the invention.
