Description
Sistema de giro, colocación, desplazamiento y medida de precisión de láminas de vidrio en máquinas de corte.System of rotation, placement, displacement and precision measurement of glass sheets in cutting machines.
El objetivo de la presente patente de invención es presentar un nuevo sistema automático de giro, colocación, desplazamiento y medida de precisión de láminas de vidrio de diferentes medidas y espesores en máquinas de corte, mediante un conjunto de ventosas con movimientos independientes entre sí, así como de un sistema de medida de precisión.The purpose of the present invention patent is to present a new automatic system of rotation, placement, displacement and precision measurement of glass sheets different sizes and thicknesses in cutting machines, by means of a set of suction cups with independent movements with each other as well as of a precision measurement system.
Esta invención tiene su principal campo de aplicación en la industria de fabricación de máquinas de corte de vidrio.This invention has its main field of Application in the cutting machine manufacturing industry of glass.
En el actual estado de la técnica, son bien conocidas las máquinas de corte con empuje de las láminas de vidrio mediante aire comprimido. No obstante, el giro de las grandes planchas de vidrio se viene realizando de una forma manual, ya que debido al empuje del aire comprimido sobre la lámina de vidrio, un operario puede mover la lámina con un relativo bajo esfuerzo.In the current state of the art, they are fine Known cutting machines with glass sheet thrust by compressed air. However, the big turn glass plates are being made in a manual way, since due to the push of compressed air on the glass sheet, a Operator can move the blade with a relative low effort.
Los diversos intentos por automatizar el procedimiento de giro se han saldado con un relativo fracaso ya que no han sabido resolver los problemas de colocación por la enorme inercia que presentan las láminas de vidrio. Así, por ejemplo, es conocido el intento de automatizar el giro mediante una única gran ventosa, que no consigue en ningún momento afinar la posición de la lámina de una manera siquiera aceptable.The various attempts to automate the turn procedure have resulted in a relative failure since have failed to solve the problems of placement because of the enormous inertia presented by glass sheets. So, for example, it is known the attempt to automate the turn using a single large suction cup, which does not at any time refine the position of the sheet in an even acceptable way.
En la patente nacional con número de publicación ES 2, 203, 352 "Instalación de corte de vidrio laminado" se describe una secuencia de giro mediante una única ventosa. Este sistema tiene una desventaja inherente al mismo como es la imposibilidad de giro de grandes láminas de vidrio. Esto es, debido a que al pasar la lámina por debajo del puente de corte en el proceso de giro, y no hacerlo en la mesa posterior, la superficie utilizada en el giro es mayor que las dimensiones del propio puente. Por otro lado, existe un límite en la adherencia de la ventosa y el vidrio, pudiendo ocurrir que la fuerza realizada en el proceso de giro sea mayor que el límite de adherencia comentado, máxime cuando la ventosa está situada en un extremo.In the national patent with publication number ES 2, 203, 352 "Installation of laminated glass cutting" a rotation sequence is described by a single suction cup. This system has an inherent disadvantage, such as the impossibility of turning large sheets of glass. This is due to the fact that when the sheet passes under the cutting bridge in the turning process, and not in the rear table, the surface used in the rotation is larger than the dimensions of the bridge itself. On the other hand, there is a limit in the adhesion of the suction cup and the glass, it being possible that the force made in the turning process is greater than the adhesion limit mentioned, especially when the suction cup is located at one end.
Para la medida de precisión de las planchas de vidrio laminado (que está formado por dos capas de vidrio monolítico unido por un polímero butiral transparente) existe otra problemática distinta a la del giro.For the precision measurement of the plates of laminated glass (which consists of two layers of glass monolithic joined by a transparent butyral polymer) there is another problematic different from the turn.
En la actualidad se emplea una mesa de corte de vidrio laminado y cuya función principal es realizada por un puente de corte dispuesto en esta mesa de corte. En dicho puente, el vidrio es cortado transversalmente por dos herramientas, superior e inferior, ubicadas en sendos patines de corte. La alimentación del vidrio se realiza mediante una mesa de carga de gran dimensión sobre la que se dispone un carro de medida que se desplaza longitudinalmente sobre ésta. El transporte se consigue mediante unas ventosas incorporadas al carro de medida, por vacío y apoyado en el colchón de aire que se crea para el flotado del vidrio (como ha sido comentado anteriormente). En todo momento es posible conocer la posición del vidrio, ya que es medido por el encóder, u otro medio de medida similar, adjunto al motor de accionamiento de dicho carro de medida. En cuanto la lámina de vidrio llega al puente de corte, éste es detectado por la fotocélula dispuesta a tal efecto, mandando la señal que hace que el encóder o elemento de medida se reinicie y comience a medir de nuevo la distancia deseada y se reinicie el proceso de corte.Currently a cutting table is used laminated glass and whose main function is performed by a bridge cutting arranged in this cutting table. On that bridge, the glass is cut transversely by two tools, upper e lower, located in two cutting skates. The feeding of glass is made using a large load table on which there is a measuring car that moves longitudinally on it. Transportation is achieved by suction cups incorporated into the measuring car, vacuum and supported in the air mattress that is created for float glass (such as has been commented previously). At all times it is possible know the position of the glass, as it is measured by the encoder, or other similar measuring means, attached to the drive motor of said measuring car. As soon as the glass sheet reaches the cutting bridge, this is detected by the photocell arranged to such effect, sending the signal that makes the encoder or element of measure restart and start measuring the desired distance again and restart the cutting process.
Como se ha descrito, las láminas de vidrio tienen una capa transparente de butiral entre las dos placas de monolítico, empleando diferentes metodologías para cortarlo (calentando y estirando, manualmente con una cuchilla, etc.). Si es cortado mediante estirado, como es mayoría en la industria, suelen quedar rebabas de butiral en los bordes, siendo esto la fuente principal de problemas, dado que la fotocélula detecta antes que al vidrio al butiral, acarreando un error de medida no deseable puesto que el encóder se reinicia antes y la medida real es menor que la deseada.As described, the glass sheets they have a transparent layer of butyral between the two plates of monolithic, using different methodologies to cut it (by heating and stretching, manually with a blade, etc.). Yes it is cut by stretching, as is the majority in the industry, usually butiral burrs remain at the edges, this being the source main problem, since the photocell detects before glass to butyral, causing an undesirable measurement error set that the encoder is restarted before and the actual measurement is less than the desired.
La solución evidente es cortar manualmente con cuchillas los salientes de butiral de cada hoja antes de cargar, siendo un proceso que resulta totalmente ineficaz e improductivo desde el punto de vista de la rentabilidad económica.The obvious solution is to cut manually with blades the butiral protrusions of each sheet before loading, being a process that is totally ineffective and unproductive from the point of view of economic profitability.
Para paliar o en su caso eliminar todos los problemas arriba mencionados, se presenta el sistema de giro, colocación, desplazamiento y medida de precisión de láminas de vidrio en máquinas de corte, objeto de la presente patente de invención.To alleviate or, where appropriate, eliminate all problems mentioned above, the turning system is presented, placement, displacement and precision measurement of sheets of glass in cutting machines, object of the present patent of invention.
Para realizar el giro de la lámina de vidrio, se dispone de una serie de elementos principales:To rotate the glass sheet, it is It has a series of main elements:
- --
- Ventosa del eje de ordenadas: Situada en el patín de corte de la máquina, realiza un movimiento longitudinal en el eje de ordenadas (eje Y) a lo largo del puente de corte. Posee movimiento de giro libre sobre su propio eje Z. Los movimientos son facilitados por un motor u otro tipo de accionamiento colocado a tal efecto.Ordinate shaft suction cup: Located in The machine cutting skate, performs a longitudinal movement on the ordinate axis (Y axis) along the cutting bridge. It has free spin movement on its own Z axis. movements are facilitated by an engine or other type of drive placed for this purpose.

- Carro de ventosas en el eje de abscisas: Se trata de un carro donde se ubican de forma paralela dos ventosas, una de ellas con giro libre sobre su propio eje Z, y como su propio nombre indica, con un desplazamiento longitudinal en el eje de abscisas (eje X), incluyendo un pequeño recorrido en el eje Y para escuadrar y facilitar el amarre del cristal. Los movimientos son facilitados por un motor u otro accionamiento similar colocado a tal efecto.Car of suction cups on the abscissa axis: This is a car where they place two suckers in parallel, one of them with free spin on its own Z axis, and as its own name indicates, with a longitudinal displacement in the abscissa axis (X axis), including a small path on the Y axis to square and facilitate the mooring of the glass. The movements are facilitated by a motor or other similar drive placed to such effect.

- Regle de colocación y escuadrado: Situado en el carro de ventosas anteriormente descrito y que se activa mediante un cilindro para escuadrar el cristal con el eje de corte.Rule of placement and squaring: Located in the suction cup car described above and activated by a cylinder to square the glass with the cutting axis.
Para realizar el giro de la lámina de vidrio se emplean las ventosas del eje de ordenadas y una de las ventosas del eje de abscisas, mediante una combinación de las secuencias de programación, velocidades y aceleraciones de los motores encargados de activar los desplazamientos longitudinales de las diferentes ventosas. El agarre de la lámina de vidrio por las ventosas se realiza mediante vacío, y el desplazamiento está apoyado en gran medida por el colchón de aire creado y repartido por toda la mesa.To rotate the glass sheet, they use the suction cups of the ordinate shaft and one of the suction cups of the abscissa axis, by a combination of the sequences of programming, speeds and accelerations of the engines ordered of activating the longitudinal displacements of the different suction cups. The grip of the glass sheet by the suction cups is performed by vacuum, and the displacement is supported greatly measured by the air mattress created and distributed throughout the table.
Existen dos formas de girar la lámina de vidrio. En la primera forma la lámina se encontraría dispuesta verticalmente respecto del eje de abscisas, mientras que en la segunda forma de giro, la lámina se encontraría dispuesta horizontalmente respecto del eje de abscisas.There are two ways to rotate the glass sheet. In the first form the sheet would be arranged vertically with respect to the abscissa axis, while in the second form of rotation, the sheet would be arranged horizontally with respect to the abscissa axis.
En la primera forma de giro, la secuencia de giro parte de una posición inicial con las ventosas sujetando la lámina de vidrio mediante la ventosa del eje Y, y una de las ventosas del eje X. La ventosa del eje Y se encontraría en uno de los extremos de la lámina de vidrio, mientras que la ventosa del eje X se encontraría en la posición cero de su eje de movimiento.In the first form of rotation, the sequence of Turn part of an initial position with the suction cups holding the glass sheet by the suction cup of the Y axis, and one of the suction cups of the X axis. The suction cup of the Y axis would be in one of the ends of the glass sheet while the suction cup of the X axis would be in the zero position of its axis movement.
En las posiciones intermedias, la ventosa del eje de ordenadas descendería longitudinalmente respecto de su eje, coordinadamente con el movimiento del carro del eje X, que avanzaría hacia la derecha longitudinalmente en su eje hasta que toda la lámina se encontrase en una posición horizontal respecto del eje de abscisas.In the intermediate positions, the suction cup ordinate axis would descend longitudinally with respect to its axis, in coordination with the movement of the X-axis carriage, which would advance to the right longitudinally on its axis until the entire sheet was in a horizontal position with respect to the shaft of abscissa.
La segunda forma de girar las láminas de vidrio repetiría la secuencia inversamente, es decir, partiendo de la lámina de vidrio en posición horizontal respecto del eje de abscisas, llegaríamos a la posición vertical respecto de este eje. La segunda ventosa del carro del eje de abscisas, se utiliza conjuntamente con la primera ventosa del carro, para terminar la colocación de la lámina de vidrio, arrastrándola hasta el regle de colocación y escuadre, tomando la lámina de vidrio desde su posición central mediante un pequeño desplazamiento en el eje Y que se dota a las ventosas del carro.The second way to rotate the glass sheets I would repeat the sequence inversely, that is, starting from the glass sheet horizontally relative to the axis of abscissa, we would reach the vertical position with respect to this axis. The second suction cup of the abscissa axle carriage is used together with the first suction cup of the car, to finish the placement of the glass sheet, dragging it to the edge of placement and square, taking the glass sheet from its central position by a small displacement in the Y axis that the suction cups are equipped with the car.
Esta segunda ventosa del carro del eje de abscisas, también se utiliza conjuntamente con la primera ventosa del carro en las ocasiones que se quiere desplazar la lámina cortada o girada en los dos sentidos del eje X, tanto para evacuarla al operario o acercarla al puente de corte y colocarla posteriormente.This second suction cup of the axle carriage abscissa, also used in conjunction with the first suction cup of the car on the occasions when you want to move the sheet cut or rotated in both directions of the X axis, both for evacuate it to the operator or bring it closer to the cutting bridge and place it later.
Por otro lado, para la medida de precisión de las láminas de vidrio se dispone de un sistema mecánico formado por una pieza metálica, unida por su parte central a un sistema soporte mediante un eje, el cual se utiliza al mismo tiempo para que la pieza gire sobre éste.On the other hand, for the precision measurement of The glass sheets have a mechanical system formed by a metal part, joined by its central part to a support system by an axis, which is used at the same time so that the piece turn on this one.
En la parte inferior del soporte se encuentra un detector del tipo inductivo que en todo momento está detectando a la pieza metálica. Un cilindro neumático es el encargado de elevar la pieza soporte y consigo la metálica una distancia cualquiera sobre el nivel de la mesa antes que el vidrio se acerque. Esta distancia es constante, válida para todos los espesores de vidrio actuales y que nunca llegarán a tocar el butiral, gracias a unos rodillos usados para el apoyo del vidrio.At the bottom of the support is a inductive type detector that is detecting at all times The metal piece. A pneumatic cylinder is responsible for raising the support piece and I get the metal any distance on the table level before the glass approaches. This distance is constant, valid for all glass thicknesses current and they will never touch the butiral, thanks to some rollers used for glass support.
Cuando el vidrio, y no el butiral, toca la pieza metálica, ésta bascula sobre el eje, el detector inductivo deja de detectar la pieza y envía una señal al encóder, o elemento de medida, para que se reinicie y comience a contar la longitud deseada.When the glass, and not the butiral, touches the piece metal, this scales on the axis, the inductive sensor stops detect the part and send a signal to the encoder, or element of measure, to restart and start counting the length desired.

Como es posible observar en las figuras adjuntas, el sistema de giro, colocación desplazamiento y medida de precisión de láminas de vidrio (9) en máquinas de corte (1), objeto de la presente patente de invención, está compuesto básicamente por una ventosa (4) en el eje X, integrada dentro de un patín de corte (3), con movimiento longitudinal único el eje de ordenadas, a lo largo del puente de corte (2). Así mismo, se presenta el carro de ventosas (6) en el eje de abscisas, carro (6) donde se ubican de forma paralela dos ventosas (5 y 7). La ventosa (5) es la más cercana a la ventosa (4) del eje Y, mientras que la ventosa (7) está más alejada. Una de las ventosas (5 y 7) dispone de giro libre en el eje Z. Como su propio nombre indica, disponen de un desplazamiento longitudinal en el eje de abscisas (eje X), incluyendo un pequeño recorrido en el eje Y para su colocación óptima. Los movimientos son facilitados por un motor colocado a tal efecto. El regle de colocación y escuadrado (8) está situado en el mismo carro de ventosas (6), se activa mediante un cilindro para referenciar la colocación.As it is possible to observe in the figures attached, the rotation system, displacement placement and measurement of precision of glass sheets (9) in cutting machines (1), object of the present invention patent, it is basically composed of a suction cup (4) on the X axis, integrated into a cutting skate (3), with a single longitudinal movement, the ordinate axis, at length of the cutting bridge (2). Likewise, the car of suction cups (6) on the abscissa axis, carriage (6) where they are located parallel form two suction cups (5 and 7). The suction cup (5) is the most close to the suction cup (4) of the Y axis, while the suction cup (7) is more remote. One of the suction cups (5 and 7) has a free spin on the Z axis. As the name implies, they have a longitudinal displacement in the abscissa axis (X axis), including a small path on the Y axis for placement optimal The movements are facilitated by an engine placed to such effect. The positioning and square rule (8) is located in the same suction cup car (6), is activated by a cylinder to reference the placement.
La secuencia de giro parte de una posición inicial donde se sujeta la lámina de vidrio (9) mediante la ventosa del eje Y (4), y la ventosa (5) del eje X. La ventosa (4) del eje Y se encontraría en uno de los extremos de la lámina de vidrio (9), mientras que la ventosa (5) del eje X se encontraría en la posición cero de su eje de movimiento. En las posiciones intermedias, la ventosa (4) del eje de ordenadas descendería longitudinalmente respecto de su eje (el puente de corte (2)), coordinadamente con el movimiento del carro (6) del eje X, que avanzaría hacia la derecha a lo largo de su eje, hasta que toda la lámina (9) se encontrase en una posición horizontal respecto del eje de abscisas (X). La segunda forma de girar las láminas de vidrio repetiría la secuencia inversamente, es decir, partiendo de la lámina de vidrio (9) en posición horizontal respecto del eje de abscisas (X), llegaríamos a la posición vertical respecto de este eje X.The turn sequence starts from one position initial where the glass sheet (9) is held by the suction cup of the Y axis (4), and the suction cup (5) of the X axis. The suction cup (4) of the Y axis would be at one end of the glass sheet (9), while the suction cup (5) of the X axis would be in the position zero of its axis of motion. In intermediate positions, the suction cup (4) of the ordinate axis would descend longitudinally with respect to its axis (the cutting bridge (2)), in coordination with the movement of the carriage (6) of the X axis, which would advance to the right along its axis, until the entire sheet (9) was in a horizontal position with respect to the abscissa axis (X). The second way of rotating the glass sheets would repeat the sequence conversely, that is, starting from the glass sheet (9) in horizontal position with respect to the abscissa axis (X), we would reach the vertical position with respect to this X axis.
La ventosa (7) del carro (6) del eje de abscisas X, se utiliza conjuntamente con la ventosa (5) del carro (6) para terminar la colocación de la lámina de vidrio (9), arrastrándola hasta el regle de colocación y escuadre (8). Las ventosas (5 y 7) del carro (6) se utilizan conjuntamente también en las ocasiones que se quiere desplazar la lámina (9) cortada o girada en los dos sentidos del eje X, tanto para evacuarla al operario o acercarla al puente de corte (2) y colocarla posteriormente.The suction cup (7) of the carriage (6) of the abscissa axis X, is used in conjunction with the suction cup (5) of the car (6) to finish the placement of the glass sheet (9), dragging it up to the placement and square rule (8). The suction cups (5 and 7) of the car (6) are also used together on the occasions that you want to move the sheet (9) cut or rotated in both senses of the X axis, both to evacuate it to the operator or bring it closer to the cutting bridge (2) and place it later.
Para la medida de precisión en el corte de la lámina de vidrio (9) se dispone de un sistema mecánico formado por una pieza metálica (41), unida por su parte central a un soporte (44) mediante un eje (42), el cual se utiliza al mismo tiempo para queda pieza (41) gire sobre éste.For the measurement of precision in the cutting of the glass sheet (9) has a mechanical system formed by a metal part (41), joined by its central part to a support (44) by means of an axis (42), which is used at the same time to piece remains (41) turn on it.
En la parte inferior del soporte (44) se encuentra un detector (43) del tipo inductivo que, en todo momento, está detectando a la pieza metálica (41). Un cilindro neumático (45) es el encargado de elevar la pieza soporte (44), y consigo la metálica (41), una distancia sobre el nivel de la mesa (1) antes que el vidrio (9) se acerque. Esta distancia es constante, válida para todos los espesores de vidrio (9) actuales y tal que facilite que nunca se llegue a tocar el butiral, gracias a los rodillos (46) presentes sobre la pieza soporte (44).At the bottom of the support (44) you find a detector (43) of the inductive type that, at all times, is detecting the metal part (41). A pneumatic cylinder (45) is responsible for raising the support piece (44), and I get the metal (41), a distance above table level (1) before the glass (9) approaches. This distance is constant, valid for all current glass thicknesses (9) and such that it facilitates the butyral is never touched, thanks to the rollers (46) present on the support piece (44).
Cuando el vidrio (9), y no el butiral, toca la pieza metálica (41), ésta bascula sobre el eje (42), el detector (43) inductivo deja de detectar la pieza (41) y envía una señal a un encóder o elemento de medida para que se reinicie y comience a contar la longitud deseada.When the glass (9), and not the butiral, touches the metal part (41), this scales on the shaft (42), the detector (43) inductive stops detecting part (41) and sends a signal to an encoder or measuring element to restart and start Count the desired length.
