OBJETO DE LA INVENCIÓNOBJECT OF THE INVENTION
La presente invención, según lo expresa el enunciado de esta memoria descriptiva se refiere a un sistema para la detección de obstáculos en vehículos, aplicado a máquinas de lavado, con el que se aportan notables ventajas en este sector de la industria, al poderse detectar elementos del automóvil de muy poco espesor, tal como antenas. ANTECEDENTES DE LA INVENCIÓNThe present invention, as expressed in the statement of this specification refers to a system for the detection of obstacles in vehicles, applied to washing machines, which provide significant advantages in this sector of the industry, to detect elements Very thin car, such as antennas. BACKGROUND OF THE INVENTION
Actualmente, la detección de obstáculos en el contorno de vehículos, tales como antenas de recepción de datos, bacas, bultos colocados en las bacas, etc., se realiza mediante la utilización de fotocélulas, si bien estos dispositivos no pueden detectar objetos de espesor mínimo como son determinados tipos de antenas.Currently, the detection of obstacles in the contour of vehicles, such as data reception antennas, roof racks, packages placed in the roof racks, etc., is carried out by using photocells, although these devices cannot detect objects of minimum thickness How are certain types of antennas.
DESCRIPCIÓN DE LA INVENCIÓNDESCRIPTION OF THE INVENTION
En lineas generales, el sistema para la detección de obstáculos en vehículos, aplicado a máquinas de lavado, objeto de la presente invención, da solución a dicho problema al incorporar unas células láser como elemento emisor y receptor, detectándose asi de forma perpendicular a la dirección de avance del vehículo, elementos u obstáculos de muy pequeña dimensión en el sentido de avance del vehículo, del orden de un milímetro o menos, debido a la exactitud que se consigue con el haz láser.In general, the system for the detection of obstacles in vehicles, applied to washing machines, object of the present invention, solves this problem by incorporating laser cells as emitting and receiving element, thus being detected perpendicular to the direction of advance of the vehicle, elements or obstacles of very small dimension in the direction of advance of the vehicle, of the order of a millimeter or less, due to the accuracy achieved with the laser beam.
Este sistema de detección por haz láser no ha sido utilizado por ningún fabricante de maquinaria de lavado de vehículos, por el mero hecho de que el emisor láser es muy susceptible de "enmascaramiento" por la acción del agua, y por tanto en esta aplicación continuamente se está trabajando con agua a presión, productos jabonosos, etc., y en definitiva se opera en un medio poco recomendable para el uso de tales dispositivos, excepto que se tomen una serie de medidas que son precisamente el objeto de la
presente invención.This laser beam detection system has not been used by any manufacturer of vehicle washing machinery, due to the mere fact that the laser emitter is very susceptible to "masking" by the action of water, and therefore in this application continuously It is working with pressurized water, soapy products, etc., and ultimately it is operated in a medium not recommended for the use of such devices, unless a series of measures are taken that are precisely the object of the present invention
Para ello, el elemento emisor definido por un puntero de rayos láser está montado en un cuerpo envolvente que le protege, dispuesto en un soporte solidario del puente móvil de la estación de lavado, saliendo el haz láser por un orificio axial de pequeño calibre.For this, the emitting element defined by a laser pointer is mounted on a protective body, arranged in a support of the mobile bridge of the washing station, leaving the laser beam through an axial bore of small caliber.
El elemento receptor del haz láser está acoplado a otro cuerpo enfrentado al anterior y sujeto de forma similar al puente de lavado, presentando también un orificio axial de pequeño calibre por el cual entra la señal del emisor a la vez que se calibra el tamaño del objeto a detectar.The laser beam receiver element is coupled to another body facing the previous one and similarly attached to the wash bridge, also presenting a small bore axial hole through which the emitter signal enters while the object size is calibrated to detect.
Este cuerpo del elemento emisor ofrece una cámara interior por su configuración tubular a la que se hace llegar aire a presión por un orificio radial, saliendo el aire por el orificio de paso del haz, efectuando un barrido de las pequeñas gotas de liquido que hubieran podido obstaculizar la salida del haz láser. Esta cámara por la que pasa el haz láser está cerrada por la cara frontal del propio puntero emisor roscado en la embocadura posterior del cuerpo, se inicia de forma cilindrica y después cónicamente hasta alcanzar el orificio de salida. En una zona media de esta superficie cónica se encuentra el orificio de entrada del aire a presión para efectuar un perfecto barrido.This body of the emitting element offers an inner chamber by its tubular configuration to which air under pressure is sent through a radial orifice, the air coming out through the passage hole of the beam, sweeping the small drops of liquid that could have been obstruct the output of the laser beam. This chamber through which the laser beam passes is closed by the front face of the threaded emitter pointer itself in the rear mouth of the body, starts cylindrical and then conically until it reaches the exit hole. In a middle area of this conical surface is the entrance hole of the pressurized air to effect a perfect sweep.
Además, para limpiar perfectamente la cámara, existe un orificio radial por el que también sale el aire a presión, practicado precisamente en la parte inferior de la superficie cilindrica inicial de la cámara, la cual tiene muy poca amplitud y forma una pestaña anular de tope de introducción del puntero emisor del láser, enlazando esta superficie cilindrica con la cónica.In addition, to perfectly clean the chamber, there is a radial orifice through which the pressurized air also exits, practiced precisely at the bottom of the initial cylindrical surface of the chamber, which has very little amplitude and forms an annular stop flange of introduction of the laser emitting pointer, linking this cylindrical surface with the conical.
El orificio radial de salida de aire a presión ocupa por tanto una posición retrasada respecto del plano ortogonal pasante por el orificio radial de entrada del aire a presión que accede desde un conducto externo,
estando dicho orificio radial de salida en una posición contigua a la cara frontal del puntero emisor y también en la parte inferior del cuerpo.The radial orifice of pressurized air outlet thus occupies a delayed position with respect to the orthogonal plane through the radial orifice of pressure air entering from an external duct, said radial outlet opening being in a position adjacent to the front face of the emitting pointer and also in the lower part of the body.
La fuente de aire a presión trabaja en continuo, al menos durante todo el ciclo de lavado que realiza la máquina, para prevenir la entrada de agua que impedirla el correcto funcionamiento del emisor.The source of pressurized air works continuously, at least during the entire washing cycle performed by the machine, to prevent the entry of water that prevents the correct operation of the emitter.

DESCRIPCIÓN DE LA FORMA DE REALIZACIÓN PREFERIDA Haciendo referencia a la numeración adoptada en las figuras podemos ver cómo el sistema para la detección de obstáculos en vehículos, aplicado a máquinas de lavado, que la invención propone, tal y como se observa en la figura 1, consiste en situar unas células láser constitutivas del elemento emisor 1 del haz láser y del elemento receptor 2 del mismo, en sendos soportes 3 solidarios al puente 4 de lavado .DESCRIPTION OF THE PREFERRED EMBODIMENT With reference to the numbering adopted in the figures we can see how the system for the detection of obstacles in vehicles, applied to washing machines, which the invention proposes, as observed in Figure 1, it consists of locating laser cells constituting the emitting element 1 of the laser beam and the receiving element 2 thereof, in two supports 3 integral to the washing bridge 4.
Este sistema de detección comanda los movimientos verticales del puente 4 para salvar obstáculos aunque sean de muy pequeña dimensión en el sentido de avance relativo
- A - del vehículo y puente 4, del orden de 1 mm o incluso menos como hemos dicho anteriormente.This detection system commands the vertical movements of bridge 4 to overcome obstacles even if they are very small in the direction of relative advancement - A - of the vehicle and bridge 4, of the order of 1 mm or even less as we have said before.
Esto es posible al proteger del agua principalmente al elemento emisor 1 para que salga limpio el haz láser 5, ya que el cuerpo receptor 2 capta este haz aunque se interponga cualquier gota de agua u otra sustancia que pueda depositarse en el exterior de su zona de captación.This is possible by mainly protecting the emitting element 1 from water so that the laser beam 5 comes out clean, since the receiving body 2 captures this beam even if any drop of water or other substance that can be deposited outside its area of interposition is interposed. catchment.
El elemento emisor 1 como se ve más claramente en la figura 1, está formado por el cuerpo 6 de forma general troncocónica y tubular, que recibe coaxialmente el puntero emisor propiamente dicho 7 hasta el tope de introducción que define una pestaña anular 8 de poca amplitud, a partir de la cual se estrecha cónicamente hasta alcanzar el orificio axial 9 de salida del haz láser 5. Se forma una cámara 10 recorrida por el haz láser 5 hasta que sale al exterior .The emitter element 1, as seen more clearly in Figure 1, is formed by the body 6 in a generally conical and tubular shape, which coaxially receives the emitter pointer itself 7 to the introduction stop defining an annular flange 8 of low amplitude , from which it narrows conically until reaching the axial opening 9 of the laser beam 5. A chamber 10 is formed along the laser beam 5 until it exits outside.
Para salvar el problema que supone el agua que pudiera entrar o depositarse en el orificio axial 9, el cuerpo 6 construido preferentemente de un material polimérico o similar, lleva acoplada una conducción externa 11 para inyectar aire a presión al interior de la cámara 10 por un orificio radial 12 del mismo. Este aire a presión sale por el mismo orificio axial 9 de salida del haz láser 5 barriendo perfectamente la boca de salida de éste. Además, se ha previsto otro orificio radial 13 también de salida del aire que accede a la cámara 10, localizado en un punto inferior de la superficie cilindrica de la pestaña anular 8, quedando así próximo a la superficie frontal. El aire inyectado barre y elimina cualquier gotita que haya en el interior de la cámara 10.To overcome the problem of the water that could enter or deposit in the axial hole 9, the body 6 preferably constructed of a polymeric material or the like, has an external conduit 11 coupled to inject air under pressure into the chamber 10 by a radial hole 12 thereof. This pressurized air exits through the same axial opening 9 of the laser beam 5 perfectly sweeping the outlet of the latter. In addition, another radial orifice 13 is also provided for the air outlet that accesses the chamber 10, located at a lower point of the cylindrical surface of the annular flange 8, thus being close to the front surface. The injected air sweeps and removes any droplets inside the chamber 10.
En la figura 4 se representa el elemento receptor 2 definido por el tubo receptor 14 del haz láser 5 acoplado al cuerpo 15 instalado en otro soporte 3 solidario del puente 4 de lavado. El cuerpo 15 tiene una cámara 16 que
comunica con el orificio axial 17 de entrada del haz láser 5.Figure 4 shows the receiver element 2 defined by the receiver tube 14 of the laser beam 5 coupled to the body 15 installed in another support 3 integral with the washing bridge 4. The body 15 has a chamber 16 that communicates with the axial bore 17 of the laser beam 5.
Los cuerpos 6 y 15 de los elementos emisor 1 y receptor 2 respectivamente, se sujetan convencionalmente de i forma regulable a los soportes 3 mediante tornillos 18 y resortes coaxiales 19.
The bodies 6 and 15 of the emitting and receiving elements 2 respectively, are conventionally fastened in an adjustable way to the supports 3 by means of screws 18 and coaxial springs 19.
