DISPOSITIVO LOCALIZADOR DE CILINDROS E INSTALACIÓN QUE LO COMPRENDE CYLINDER AND INSTALLATION LOCATOR DEVICE INCLUDING IT
DESCRIPCIÓNDESCRIPTION
La presente invención hace referencia a un dispositivo localizador de cilindros.The present invention refers to a cylinder locator device.
En particular, la presente invención hace referencia a un dispositivo de localización de cilindros que resulta especialmente ventajoso en su aplicación a instalaciones de producción y/o montaje de vehículos, si bien la invención no queda necesariamente limitada a dicha aplicación.In particular, the present invention refers to a cylinder locating device that is especially advantageous in its application to production and / or vehicle assembly facilities, although the invention is not necessarily limited to said application.
Las líneas de producción y/o las líneas de montaje de automóviles, tales como, por ejemplo, las líneas de producción de carrocerías en el sector del automóvil, presentan una gran cantidad de cilindros neumáticos (o hidráulicos) .Production lines and / or automobile assembly lines, such as, for example, body production lines in the automobile sector, have a large number of pneumatic (or hydraulic) cylinders.
Habitualmente, dichos cilindros presentan unos sensores de posicionamiento del cilindro (abierto/cerrado) que están conectados a un sistema de comunicación de datos (p. ej . un sistema tipo ^interbus') los cuales envían dicha información a un dispositivo de control, habitualmente un PLC y/o ordenador.Usually, said cylinders have cylinder positioning sensors (open / closed) that are connected to a data communication system (eg, an "interbus" type system) which send said information to a control device, usually a PLC and / or computer.
Cuando acaece una avería en el cilindro (p. ej . encallamiento en su recorrido) o una avería en los sensores, la posición del cilindro no queda definida y el dispositivo de control se ve obligado a parar la producción. Al encontrarse la línea parada, resulta crítico encontrar en el menor tiempo posible el cilindro que presenta la anomalía y solucionar ésta para que la línea pueda volver a producir. Para localizarlos, el dispositivo de control de tipo conocido puede proporcionar los datos relativos a un identificador del cilindro que corresponde con un identificador situado en una etiqueta dispuesta junto al cilindro y una indicación de la estación o zona en la que se encuentra. Para facilitar la localización del cilindro, también es conocida la disposición de tres diodos en el mismo con indicación de posición abierta, cerrada o posición de alimentación. Sin embargo, dada la complejidad de las lineas, éstas pueden presentar una gran cantidad de cilindros, pudiéndose encontrar éstos en posiciones de difícil acceso, visibilidad, e incluso pueden quedar tapados por otros dispositivos de la línea-f' Por lo tanto, el dispositivo localizador . óptico puede no ser de ayuda. Además, toda etiqueta es susceptible de deteriorarse hasta el punto de impedir la lectura del identificador de cilindro, o bien ésta debe ser leída desde una posición tal que la agudeza visual del usuario no le permite discernir el identificador. Además, el inventor ha advertido que, a veces, debido la agitación que provoca la parada de la línea, el operario olvida el número identificador proporcionado por el dispositivo de control. En definitiva, resulta complicado localizar el cilindro anómalo. Como consecuencia de estas dificultades, el inventor ha observado tiempos de parada de línea por anomalía en la señal del cilindro de hasta 10 minutos. Durante este tiempo, una línea habitual de montaje de automóviles deja de producir unas 13 unidades. Es un objetivo de la presente invención dar a conocer medios para poder reducir al máximo los tiempos de parada en lineas automatización y/o montaje por anomalía en un cilindro mecánico y/o eléctrico.When a breakdown occurs in the cylinder (eg run-up in its path) or a breakdown in the sensors, the position of the cylinder is not defined and the control device is forced to stop production. When the stopped line is found, it is critical to find in the shortest possible time the cylinder that presents the anomaly and solve it so that the line can re-produce. To locate them, the control device of known type can provide the data relating to an identifier of the cylinder corresponding to an identifier located on a label disposed next to the cylinder and an indication of the station or zone in which it is located. To facilitate the location of the cylinder, the arrangement of three diodes therein with indication of open, closed position or power position is also known. However, given the complexity of the lines, they can have a large number of cylinders, which can be found in positions of difficult access, visibility, and can even be covered by other devices of the line-f ' Therefore, the device locator Optical may not help. In addition, any label is susceptible to deterioration to the point of preventing the reading of the cylinder identifier, or it must be read from a position such that the user's visual acuity does not allow him to discern the identifier. In addition, the inventor has warned that, sometimes, due to the agitation caused by the stop of the line, the operator forgets the identification number provided by the control device. In short, it is difficult to locate the anomalous cylinder. As a consequence of these difficulties, the inventor has observed line stop times due to anomaly in the cylinder signal of up to 10 minutes. During this time, a usual car assembly line stops producing about 13 units. It is an objective of the present invention to give Know means to be able to reduce to the maximum the downtimes in lines automation and / or assembly by anomaly in a mechanical and / or electric cylinder.
En particular, la presente invención consiste en un dispositivo localizador de cilindros neumáticos o hidráulicos en lineas automatizadas de producción y/o montaje, caracterizado porque comprende un avisador acústico y medios para accionar dicho avisador acústico para que emita una señal acústica de aviso en función de una señal o señales de posición anómala o correspondiente a una anomalía emitida por el cilindro a localizar.In particular, the present invention consists of a locator device of pneumatic or hydraulic cylinders in automated production and / or assembly lines, characterized in that it comprises an acoustic warning and means for actuating said acoustic warning to emit an acoustic warning signal as a function of an abnormal position signal or signals or corresponding to an anomaly emitted by the cylinder to be located.
Este dispositivo permite localizar el cilindro gracias a la señal acústica emitida por el avisador en el caso de situación anómala en el cilindro. De esta manera, el cilindro anómalo podrá ser localizado con independencia de que la etiqueta identificadora sea incorrecta o esté dañada, o que ésta no sea accesible, y sin necesidad de memorizar el localizador del cilindro. El dispositivo también puede ser utilizado ventajosamente en las puestas en marcha, permitiendo que éstas resulten más rápidas y cómodas.This device allows to locate the cylinder thanks to the acoustic signal emitted by the alarm in the case of abnormal situation in the cylinder. In this way, the anomalous cylinder can be located regardless of whether the identifying label is incorrect or damaged, or that it is not accessible, and without the need to memorize the cylinder locator. The device can also be used advantageously in startups, allowing them to be faster and more comfortable.

El dispositivo objeto de la presente invención también podrá incorporar uno o varios generadores de señales luminosas, preferentemente intermitentes, que se activan de - A -The device object of the present invention may also incorporate one or more light signal generators, preferably intermittent, which are activated by - TO -
Ia misma manera que el generador de señal acústica, y que pueden servir, en determinados casos, de comprobación para el operario.The same way as the acoustic signal generator, and which can, in certain cases, serve as a check for the operator.
En una realización especialmente preferente, el dispositivo avisador objeto de la presente invención se configura como un dispositivo independiente que, mediante dos conectores, puede conectarse entre el generador de señales de posición de un cilindro y un dispositivo de control, situándose físicamente, preferentemente, en las proximidades del cilindro.In a particularly preferred embodiment, the warning device object of the present invention is configured as an independent device which, by means of two connectors, can be connected between the generator of position signals of a cylinder and a control device, being physically, preferably, placed in the vicinity of the cylinder.

Internamente, los citados medios para activar del dispositivo comprenderán un comparador, para comparar una señal de entrada con unos valores predeterminados, con el fin de generar una señal de accionamiento del avisador acústico en el caso de que la señal corresponda con una anomalía, y un temporizador que genera un retardo en la señal de accionamiento del avisador acústico y/o luminoso generado por el comparador. Mediante el temporizador se evita la generación de falsos avisos producidos por retardos o situaciones intermedias normales del cilindro. Asimismo, el dispositivo podrá comprender un aislamiento eléctrico de la señal de entrada (tal como un aislamiento galvánico u optoeléctrico) para evitar interferencias producidas por motores presentes en una instalación. Determinadas realizaciones del dispositivo pueden requerir un regulador de la tensión de alimentación situada a la entrada del dispositivo.Given its industrial application, the elements of the device will preferably be arranged in a closed envelope, more preferably waterproof and isolated from environmental contamination. Internally, said means for activating the device will comprise a comparator, to compare an input signal with predetermined values, in order to generate an acoustic warning signal in case the signal corresponds to an anomaly, and a timer that generates a delay in the acoustic and / or light warning signal generated by the comparator. The timer prevents the generation of false warnings caused by delays or normal intermediate situations of the cylinder. Also, the device may comprise an electrical isolation of the input signal (such as a galvanic or optoelectric isolation) to avoid interference caused by motors present in an installation. Certain device embodiments may require a regulator of the supply voltage located at the input of the device.

Asimismo, la presente invención también comprende una instalación automatizada de producción y/o montaje que comprende cilindros neumáticos y/o hidráulicos dotados de un sistema sensor de la posición de los cilindros, caracterizado porque al menos uno de los cilindros comprende un localizador según la presente invención, siendo la instalación, preferentemente, una linea de producción y/o montaje de automóviles o un robot.Likewise, the present invention also comprises an automated production and / or assembly installation comprising pneumatic and / or hydraulic cylinders provided with a cylinder position sensing system, characterized in that at least one of the cylinders comprises a locator according to the present invention, the installation being preferably a production line and / or assembly of cars or a robot.

En las figuras, se ha mostrado una posible realización del dispositivo objeto de la presente invención.In the figures, a possible embodiment of the device object of the present invention has been shown.
La realización mostrada comprende una envolvente -1-, en la que se sitúa un avisador acústico -2- con su correspondiente generador acústico -22-. En este caso particular, además, se ha dotado al avisador -2- de un generador de una señal óptica intermitente a través de un LED -21-. Para adaptarlo a ambientes industriales duros, la envolvente -1- puede ser estanca al agua y aislada de la contaminación industrial.The embodiment shown comprises an envelope -1-, in which an acoustic warning device -2- is placed with its corresponding acoustic generator -22-. In this particular case, in addition, the warning device -2- has been provided with a generator of an intermittent optical signal through an LED -21-. To adapt it to harsh industrial environments, envelope -1- can be waterproof and isolated from industrial pollution.
De la envolvente -1- salen, en el caso particular mostrado, un conector de entrada -4- y otro de salida -5-. A través del conector de entrada -4- el dispositivo recibe la señal correspondiente a la posición de un cilindro. Dicho conector de entrada -4- queda conectado tanto a un conector de salida -5- destinado a dar paso a la señal procedente del conector de entrada, como a los elementos internos del dispositivo avisador. En el caso mostrado, se han dispuesto, en línea, un regulador de la tensión de alimentación -7-, un aislamiento galvánico -6- y un comparador retardado -3-, que es utilizado como medio para activar el avisador acústico y luminoso -2-, conectados, por ejemplo según el esquema mostrado en la figura 3.From the envelope -1-, in the particular case shown, there is an input connector -4- and an output connector -5-. Through the input connector -4- the device receives the signal corresponding to the position of a cylinder. Said input connector -4- is connected both to an output connector -5- intended to give way to the signal from the input connector, as well as to the internal elements of the warning device. In the case shown, a supply voltage regulator -7-, a galvanic isolation -6- and a delayed comparator -3- have been arranged in line, which is used as a means to activate the acoustic and light warning - 2-, connected, for example according to the scheme shown in figure 3.
El regulador de tensión -7- es el encargado de proporcionar a resto de elementos del dispositivo de la tensión necesaria para su funcionamiento. Dependiendo del sistema de comunicación elegido, este regulador -7- podría no resultar necesario.The voltage regulator -7- is responsible for providing other elements of the device with the voltage necessary for its operation. Depending on the communication system chosen, this regulator -7- may not be necessary.
Tras el regulador de tensión -7- se ha situado un aislamiento galvánico -6- para controlar las señales que llegan de un cilindro a través del conector de entrada -4-, impidiendo que cualquier problema de contaminación ambiental, tal como, por ejemplo, fuertes campos electromagnéticos producidos por pinzas de soldadura de robots, que se pueden producir en determinados entornos industriales específicos .After the voltage regulator -7- a galvanic isolation -6- has been placed to control the signals that arrive from a cylinder through the input connector -4-, preventing any environmental contamination problem, such as, for example, strong fields Electromagnetic products produced by welding robots, which can be produced in certain specific industrial environments.
En el ejemplo mostrado, los medios para activar el avisador acústico comprenden un comparador -3- que dispone de un temporizador (no mostrado) . El objetivo del comparador es comparar la señal procedente de la entrada -4- con una serie de valores predeterminados . En el caso de que la señal recibida coincida con una señal de anomalía o con una señal que corresponde con un estado anómalo, el comparador genera o deja pasar una señal que activará el avisador acústico -2-In the example shown, the means for activating the acoustic alarm comprise a comparator -3- which has a timer (not shown). The objective of the comparator is to compare the signal from input -4- with a series of default values. In the event that the received signal coincides with an anomaly signal or with a signal that corresponds to an anomalous state, the comparator generates or lets in a signal that will activate the acoustic warning -2-
(y en su caso, el avisador óptico) . La señal de activación puede quedar preferentemente retardada por un temporizador para evitar falsos avisos producidos por estados intermedios del cilindro, o por situaciones anómalas de muy corta duración.(and where appropriate, the optical warning). The activation signal may preferably be delayed by a timer to avoid false warnings produced by intermediate states of the cylinder, or by anomalous situations of very short duration.
En un caso muy habitual, los cilindros poseen dos detectores de posición correspondientes con el principio y el final de carrera del cilindro. En este caso, el comparador debe elegirse y configurarse en función del tipo de señal emitida, para activar el avisador acústico en las siguientes situaciones:In a very common case, the cylinders have two position detectors corresponding to the beginning and the end of the cylinder. In this case, the comparator must be chosen and configured according to the type of signal emitted, to activate the acoustic warning in the following situations:
- no existe señal de abierto ni señal de cerrado, o - se transmiten simultáneamente las señales de abierto y cerrado.- there is no open or closed signal, or - open and closed signals are transmitted simultaneously.
El conector de salida -5- tiene como finalidad permitir el envío de la señal al dispositivo de control de la instalación de producción y/o montaje. Por último, el dispositivo mostrado en las figuras se complementa con una pinza -8- incorporada en su envolvente -1- y que puede ser útil en determinadas aplicaciones para su fijación. Evidentemente, el dispositivo podría prescindir de dicha pinza -8- sin salirse del ámbito de la presente invención.The output connector -5- is intended to allow the signal to be sent to the control device of the production and / or assembly facility. Finally, the device shown in the figures It is complemented with a clamp -8- incorporated in its enclosure -1- and that can be useful in certain applications for its fixation. Obviously, the device could dispense with said clamp -8- without leaving the scope of the present invention.
En la figura 2 se ha mostrado, de manera esquemática, un ejemplo de aplicación del dispositivo según la presente invención en una instalación automatizada de producción y/o montaje industrial, tal como, por ejemplo una linea de montaje y/o producción de automóviles o componentes de éstos, o un robot, comprendiendo dicha instalación cilindros -10- con un sistema sensor de la posición del cilindro. El conector de entrada -4- puede conectarse a la salida de señal del sistema sensor y, a su vez, el conector de salida se conecta, a través de los medios de red necesarios, a un PLC o dispositivo de control -20-. En un caso general, el dispositivo avisador puede situarse preferentemente lo más cerca posible del cilindro -10-, para facilitar la localización física de éste, especialmente cuando existe una gran cantidad de cilindros en la instalación.Figure 2 shows, schematically, an example of application of the device according to the present invention in an automated industrial production and / or assembly facility, such as, for example, a car assembly and / or production line or components thereof, or a robot, said installation comprising cylinders -10- with a cylinder position sensing system. The input connector -4- can be connected to the signal output of the sensor system and, in turn, the output connector is connected, via the necessary network means, to a PLC or control device -20-. In a general case, the warning device can preferably be located as close as possible to the cylinder -10-, to facilitate its physical location, especially when there is a large number of cylinders in the installation.
Resulta a destacar de la realización mostrada, que una avería del dispositivo no implica un malfuncionamiento o parada de todo el sistema, debido a la conexión directa que se establece entre el conector de entrada -4- y el conector de salida -5-. En definitiva, el dispositivo no afecta al funcionamiento del sistema de control de la instalación, lo único que hace es detectar la avería en el lugar en el que se produce. En general, la envolvente podría modificar su forma con respecto a lo mostrado, los tipos de conectores serán variables en función del sistema sensor y de control de la instalación, también los sistemas de acoplamiento, detectores, tipos de dispositivos luminosos y acústicos podrán ser variables en función de la aplicación, siempre y cuando permitan la consecución de la finalidad del dispositivo objeto de la presente invención. En particular, el dispositivo objeto de la presente invención podría aplicarse directamente, por ejemplo mediante un único conector, o incluso integrarse en los cilindros.It is noted from the embodiment shown, that a failure of the device does not imply a malfunction or shutdown of the entire system, due to the direct connection established between the input connector -4- and the output connector -5-. In short, the device does not affect the operation of the control system of the installation, all it does is detect the fault in the place where it occurs. In general, the envelope could modify its With respect to what has been shown, the types of connectors will vary depending on the sensor and control system of the installation, also the coupling systems, detectors, types of light and acoustic devices may be variable depending on the application, provided when they allow the achievement of the purpose of the device object of the present invention. In particular, the device object of the present invention could be applied directly, for example by a single connector, or even integrated into the cylinders.
