Description

Instalación de lavado de coches.Car wash installation.

La presente invención concierne a una instalación de lavado de coches con al menos un dispositivo de limpieza que presenta un gran número de elementos de limpieza a manera de trapos que pueden moverse a rotación y/o en traslación y que tienen cada uno de ellos un elemento de respaldo con dos capas sobrepuestas y mutuamente unidas de un material de soporte que llevan una felpa de limpieza a base de fibras de limpieza en sus lados exteriores orientados uno hacia fuera de otro, estando varios elementos de limpieza a manera de tiras colocados de manera que quedan sustancialmente yuxtapuestos en paralelo y estando unidos uno con otro en una de sus zonas extremas axiales - la zona de cabeza -. Además, la invención concierne a una disposición de elementos de limpieza para una instalación de lavado de coches.The present invention concerns an installation car wash with at least one cleaning device that It presents a large number of cleaning elements as rags that can move to rotation and / or in translation and that have each one of them a backup element with two superimposed layers and mutually joined of a support material that carry a plush of fiber-based cleaning on its outer sides oriented one out of the other, being several elements of cleaning as strips placed so that they remain substantially juxtaposed in parallel and being joined one with another in one of its axial extreme zones - the head area -. Furthermore, the invention concerns an arrangement of elements of Cleaning for a car wash facility.

En las líneas de lavado usuales hoy en día se utilizan para la limpieza de los vehículos, en primer lugar, unos cepillos rotativos que son conducidos a lo largo del vehículo. Sin embargo, en estos cepillos es desventajoso el hecho de que pueden ocasionar arañazos en la pintura del vehículo y, además, se desgastan con rapidez. Por otra parte, se logran resultados de limpieza satisfactorios con los cepillos generalmente tan sólo utilizando adicionalmente detergentes químicos, pero éstos, por un lado, son caros y, por otro lado, después del lavado tienen que ser eliminados del agua sucia de una manera costosa. Por este motivo, se utilizan en medida creciente desde hace algún tiempo en lugar de los cepillos, unos elementos de limpieza a manera de trapos que están sujetos en soportes rotativos o que pueden realizar movimientos de traslación en vaivén. Es cierto que con la utilización de estos trapos se reduce claramente la formación de arañazos en la pintura, pero sigue siendo necesaria una utilización considerable de detergentes adicionales.In the usual washing lines today used for cleaning vehicles first of all Rotating brushes that are driven along the vehicle. Without However, in these brushes the fact that they can cause scratches on the vehicle's paint and also wear quickly. On the other hand, results of satisfactory cleaning with brushes usually only using additional chemical detergents, but these, for a on the other hand, they are expensive and, on the other hand, after washing they have to be removed from dirty water in an expensive way. For this reason, it used increasingly for some time instead of brushes, cleaning elements like rags that are subject on rotating stands or that can be made reciprocating translation movements. It is true that with the Use of these rags clearly reduces the formation of scratches on the paint, but use is still necessary considerable of additional detergents.

198 11 942 A1 el emplear en instalaciones de lavado de coches unos elementos de limpieza con una felpa de limpieza a base de fibras de limpieza como la que es ya conocida por el sector doméstico, en donde se utilizan trapos de limpieza a base de felpas de limpieza, por ejemplo de las firmas Hara y Vileda. Estas felpas de limpieza tienen la ventaja de una elevada acción de limpieza en comparación con los trapos de limpieza empleados hasta ahora en el sector de las instalaciones de lavado de coches, de modo que se puede prescindir completa o casi completamente de detergentes químicos adicionales.It is also known by the DE document
198 11 942 A1 the use of cleaning elements in a car wash facility with a cleaning plush based on cleaning fibers such as that already known by the domestic sector, where plush cleaning cloths are used. cleaning, for example of the firms Hara and Vileda. These cleaning cloths have the advantage of a high cleaning action compared to the cleaning cloths used so far in the sector of car wash installations, so that additional chemical detergents can be completely or almost completely dispensed with.

Además, se conoce por el documento DE
198 11 942 el recurso de agrupar varios de estos elementos de limpieza para formar una unidad o disposición de limpieza, en donde varios elementos de limpieza están colocados entonces en forma sustancialmente yuxtapuesta en paralelo y están unidos en una zona extrema axial - la zona de la cabeza - por un fieltro de soporte que se extiende transversalmente a la dirección longitudinal de los elementos de limpieza. Una unidad así formada puede fijarse de manera sencilla a un soporte correspondiente de un dispositivo de limpieza.In addition, it is known by the DE document
198 11 942 the resource of grouping several of these cleaning elements to form a cleaning unit or arrangement, where several cleaning elements are then placed substantially juxtaposed in parallel and joined in an axial end zone - the area of the head - by a support felt that extends transversely to the longitudinal direction of the cleaning elements. A unit thus formed can be fixed simply to a corresponding support of a cleaning device.

En la práctica, se utilizan en general elementos de limpieza que poseen una anchura de aproximadamente 10 cm. Sin embargo, se ha comprobado que estos elementos de limpieza no logran en algunos casos unos resultados de limpieza óptimos, en particular cuando los elementos de limpieza no son especialmente largos, de modo que poseen una resistencia relativamente alta. En efecto, en estos casos, no se pueden alcanzar en parte las zonas de esquinas y de aristas con los elementos de limpieza.In practice, elements are generally used cleaning that have a width of approximately 10 cm. Without However, it has been proven that these cleaning elements fail in some cases optimal cleaning results, in particular when the cleaning elements are not especially long, of so that they have a relatively high resistance. Indeed, in these cases, the corner areas cannot be reached in part and of edges with the cleaning elements.

Por último, se conocen por el documento US 5,461,745 A unos elementos de limpieza configurados de tal modo que, partiendo de su extremo libre, están divididos en el centro.Finally, they are known by the US document 5,461,745 To cleaning elements configured in such a way that, starting from their free end, they are divided in the center.

Por tanto, el cometido de la invención consiste en configurar una instalación de lavado de coches de la clase citada al principio de modo que se puedan lograr resultados de limpieza óptimos. Además, se pretende indicar una disposición de limpieza para una instalación de lavado de coches de esta clase.Therefore, the purpose of the invention consists in in setting up a class car wash facility cited at the beginning so that results of optimal cleaning. In addition, it is intended to indicate a provision of cleaning for a car wash facility of this class.

Este problema se resuelve según la invención por el hecho de que los elementos de limpieza están configurados de manera que están divididos aproximadamente en el centro en una parte de su longitud, partiendo de su extremo libre opuesto a la parte de cabeza, y en el extremo de cabeza de los elementos de limpieza está cosida una respectiva inserción de fieltro para fines de refuerzo. Debido a la división realizada de los elementos de limpieza se rebaja la resistencia de estos elementos de limpieza, especialmente en sus extremos libres, hasta el punto de que se pueden limpiar fiablemente incluso sitios de difícil acceso, tales como las zonas de las esquinas. Se ha visto a este respecto que se logran resultados muy buenos cuando se efectúa la división sobre el 50 al 80% de la longitud de los elementos de limpieza.This problem is solved according to the invention by the fact that the cleaning elements are configured of so that they are divided approximately in the middle into one part of its length, starting from its free end opposite to the part of head, and at the head end of the cleaning elements is sewn a respective felt insert for reinforcement purposes. Due to the division made of the cleaning elements, reduces the resistance of these cleaning elements, especially at its free ends, to the point that they can be cleaned reliably even hard-to-reach sites, such as areas of the corners. It has been seen in this regard that they are achieved very good results when the division over 50 to the 80% of the length of the cleaning elements.

Según una forma de ejecución preferida, se ha previsto que los elementos parciales a manera de tiras formados por la división de los elementos de limpieza estén cortados también con incisiones desde sus extremos libres, estando configuradas netamente más cortas estas incisiones, que discurren también en dirección longitudinal y que parten del extremo libre, y necesitando extenderse tan sólo sobre aproximadamente 10 a 20% de la longitud de los elementos de limpieza.According to a preferred embodiment, it has been provided that the partial elements as strips formed by the division of the cleaning elements are also cut with incisions from their free ends, being configured sharply shorter these incisions, which also run in longitudinal direction and starting from the free end, and needing to extend only about 10 to 20% of the Length of cleaning elements.

En otras palabras, los elementos de limpieza dotados usualmente de una anchura de alrededor de 10 cm se subdividen por la división principal centrada en elementos parciales con una anchura de aproximadamente 5 cm y estos elementos parciales están a su vez subdivididos en sus extremos libres en tiras de aproximadamente 2,5 cm de anchura.In other words, the cleaning elements usually endowed with a width of about 10 cm subdivided by the main division centered on elements partial with a width of approximately 5 cm and these elements partials are in turn subdivided at their free ends in strips approximately 2.5 cm wide.

Las fibras de limpieza y el material de soporte del elemento de respaldo consisten de manera preferida en un material que posee una pequeña capacidad de absorción de agua para que los elementos de limpieza no resulten demasiado pesados debido a la absorción de agua. Como materiales adecuados se han acreditado, por ejemplo, poliéster, poliéter, poliamida y polipropileno, teniendo el poliéster la ventaja adicional de que ofrece una buena resistencia frente a ambientes alcalinos.Cleaning fibers and support material of the backing element preferably consist of a material that has a small water absorption capacity to that the cleaning elements are not too heavy due to water absorption As appropriate materials have been accredited, for example, polyester, polyether, polyamide and polypropylene, having polyester the additional advantage of offering a good resistance against alkaline environments.

Las dos capas de material de soporte del elemento de respaldo pueden estar unidas una con otra de cualquier manera adecuada, habiéndose acreditado como conveniente el pegar las dos capas o especialmente coserlas con un hilo de material de Kevlar resistente frente a altos valores alcalinos.The two layers of element support material backup can be attached to each other in any way adequate, having proven as convenient to paste the two layers or especially sew them with a thread of Kevlar material resistant against high alkaline values.
