La invención se refiere a un dispositivo para la medición de deformaciones dependientes de la carga de cilindros montados en cajas de laminación de bandas, con un sistema sensor óptico montado en al menos un cilindro para la detección de la flexión del cilindro con respecto al eje longitudinal del cilindro (documento EP 0 315 043 A2).The invention relates to a device for the measurement of deformations dependent on cylinder load mounted in strip lamination boxes, with a sensor system optical mounted on at least one cylinder for the detection of flexion of the cylinder with respect to the longitudinal axis of the cylinder (EP 0 315 043 A2).
El conocimiento del comportamiento de flexión y la derivación que se obtiene de ello de la carga de la caja de laminación, de la deformación del cilindro y los efectos secundarios del dispositivo de flexión de cilindro sobre la abertura entre cilindros, es esencial para una regulación de la abertura entre cilindros moderna en las cajas de laminación de bandas, en particular para la laminación de bandas finas y láminas.Bending behavior knowledge and the derivation that is obtained from it from the load of the box Lamination, cylinder deformation and side effects of the cylinder bending device over the opening between cylinders, it is essential for a regulation of the opening between Modern cylinders in strip rolling boxes, in particularly for the lamination of thin bands and sheets.
Por los documentos DE 195 47 438 y EP 1 216 766 es conocido un dispositivo de medición de contorno que trabaja sin contacto para la medición de la forma geométrica del abombamiento de cilindros montados en cajas de laminación de bandas durante el proceso de laminación. El dispositivo de medición de contorno está equipado con un soporte longitudinal que se extiende a través de la longitud del cilindro, en el que está dispuesta perpendicularmente al eje longitudinal del cilindro una pluralidad de sensores de distancia enfriados, que miden sin contacto, en particular sensores de corrientes parásitas, con distancia lateral entre sí. Con dispositivos de medición de este tipo se está en situación de medir el estado de desgaste y el abombamiento térmico de los cilindros. No obstante, una medición de la abertura entre cilindros opuesta al lugar de medición no es posible con estos dispositivos de medición, en particular teniendo en cuenta que los resultados de medición están influidos por fuerzas de peso, fuerzas de laminación y flexión, así como la existencia de eventuales cilindros intermedios.For documents DE 195 47 438 and EP 1 216 766 a contour measuring device that works without contact for measuring the geometric shape of the bulge of cylinders mounted in strip lamination boxes during the lamination process The contour measuring device is equipped with a longitudinal support that extends through the cylinder length, in which it is arranged perpendicularly to the longitudinal axis of the cylinder a plurality of sensors of cooled distance, measuring without contact, in particular sensors of parasitic currents, with lateral distance from each other. With Measuring devices of this type are in a position to measure the state of wear and thermal bulging of the cylinders. However, a measurement of the opening between cylinders opposite the measuring location is not possible with these measuring devices, in particular considering that the measurement results are influenced by weight forces, rolling forces and flexion, as well as the existence of possible cylinders intermediate
Los dispositivos de medición de la abertura entre cilindros, como son conocidos por ejemplo por los documentos US 3,102,960, el DE 29 52 232 A1 y el EP 0 250 768 A2, no permiten una medición de la abertura entre cilindros bajo carga o en la zona de la banda bajo carga.The opening measuring devices between cylinders, as they are known for example by documents US 3,102,960, DE 29 52 232 A1 and EP 0 250 768 A2, do not allow a measurement of the opening between cylinders under load or in the area of the band under load.
El dispositivo según el preámbulo descrito en el documento EP-A-0315 043 para la medición de deformaciones dependientes de la carga de los cilindros de una caja de laminación comprende por cilindro como lugar de medición dos sensores de medida, los cuales están dispuestos bajo diferentes ángulos entre sí, y dos receptores ópticos para la medición de la desviación de un rayo de luz provocada por la flexión del cilindro desde la posición nula del eje del cilindro, así como un aparato de medición para la determinación de la posición angular de los dos receptores en el instante de medición respectivo. Si se desea una determinación sincrónica en el tiempo de la fuerza de laminación y del ángulo derivado entre la fuerza de laminación y la horizontal, son necesarios dos rayos de luz focalizados sobre los dos receptores ópticos. La técnica de este dispositivo de medición conocido es muy complicada.The device according to the preamble described in the EP-A-0315 043 for the Measurement of deformations dependent on cylinder load of a rolling box comprising a cylinder as a place of measurement two measurement sensors, which are arranged under different angles to each other, and two optical receivers for the measurement of the deflection of a beam of light caused by flexion of the cylinder from the zero position of the cylinder axis, as well as a measuring device for determining the angular position of the two receivers at the respective instant of measurement. Whether you want a synchronous determination in time of the force of rolling and the angle derived between the rolling force and the horizontal, two rays of light focused on the Two optical receivers. The technique of this measuring device known is very complicated.

Las señales de medición del medidor de dilatación son transmitidas por medio de un emisor montado en la perforación de medición del cilindro a un ordenador externo para la evaluación.The content of the document JP-A-57-142719 is a measuring device for deformation determination dependent on the load of the work cylinders of a box of lamination, which is formed by a bar equipped with meters dilatation, which are inserted into a measuring hole that runs coaxial with respect to the axis of the cylinder.

Para la fabricación de bandas de laminación de alta calidad es importante conocer la flexión de los cilindros provocada por las cargas de los cilindros, tales como la fuerza de conformación, la fuerza de flexión de los cilindros para influir en la abertura entre cilindros, la fuerza de estabilización y la fuerza de peso, para ajustar por medio de miembros de ajuste conocidos de la caja de laminación, la flexión del cilindro y la basculación de los cilindros de la caja de laminación a una abertura entre cilindros adecuada al proceso de laminación. Como todos los cilindros se flexionan bajo la influencia de cargas, por ejemplo un cilindro de apoyo está sujeto también a una flexión bajo la fuerza de conformación aplicada. Esto tiene como consecuencia que la abertura entre cilindros se abre en el centro de la banda; por tanto se genera una banda defectuosa con una elevación central. Si se tiene el conocimiento sobre la flexión del cilindro de apoyo puede ser producida una compensación, por ejemplo, además de por otros miembros de ajuste también por un cilindro de apoyo con abombamiento ajustable hidráulicamente.For the manufacture of lamination bands of High quality is important to know the flexion of the cylinders caused by cylinder loads, such as the force of conformation, the bending force of the cylinders to influence the opening between cylinders, the stabilization force and the force weight, to adjust by means of known adjustment members of the rolling box, the flexion of the cylinder and the tilting of the cylinders of the rolling box at an opening between cylinders suitable for the rolling process. Like all cylinders flex under the influence of loads, for example a support cylinder is also subject to bending under force of applied conformation. This results in the opening between cylinders opens in the center of the band; so a defective band with a central elevation is generated. Whether have the knowledge about the flexion of the support cylinder can compensation is produced, for example, in addition to others adjustment members also by a support cylinder with hydraulically adjustable bulge.
La invención se propone el objeto de desarrollar un dispositivo para la medición de la flexión dependiente de la carga de cilindros montados en cajas de laminación de bandas.The invention aims to develop a device for measuring the flexion dependent on the loading of cylinders mounted in rolling mills.

El láser/matrices CCD, a diferencia de los sensores mencionados anteriormente, pueden representar sólo en su lugar de montaje desviaciones del eje longitudinal geométrico de un cilindro, sin embargo permiten además hacer afirmaciones sobre vibraciones y desviaciones de excentricidad en forma de lugar geométrico.The CCD laser / matrices, unlike the sensors mentioned above, can represent only in your mounting location deviations of the geometric longitudinal axis of a cylinder, however they also allow to make statements about vibrations and deviations of eccentricity in the form of place geometric.
La transmisión de señal de los sensores se realiza por dispositivos de transmisión correspondientes al estado de la técnica, por ejemplo de tipo óptico, eléctrico, magnético, capacitivo o radioeléctrico.The signal transmission of the sensors is performed by transmission devices corresponding to the state of the technique, for example of optical, electrical, magnetic type, capacitive or radioelectric.
Una ventaja esencial del cartucho de medición según la invención se puede ver en que el sistema sensor está montado en el cilindro protegido de cargas mecánicas y suciedades.An essential advantage of the measuring cartridge according to the invention it can be seen that the sensor system is mounted on the cylinder protected from mechanical loads and dirties
