Campo técnico de la invención La presente invención describe unas bandas de limpieza y un sistema de montaje, sujeción y recambio de las mismas a las piezas de acoplamiento para cepillos giratorios, principalmente utilizados para el lavado de vehículos, aunque también pueden ser utilizados para otros fines. Antecedentes de la invención Technical Field of the Invention The present invention describes cleaning bands and an assembly, clamping and replacement system thereof to the coupling parts for rotating brushes, mainly used for vehicle washing, although they can also be used for other purposes. . Background of the invention
En la actualidad, los cepillos giratorios tanto para máquinas de lavado de vehículos como para otros fines comprenden una sucesión de módulos que soportan unas cerdas, bandas, tiras o flecos, a la vez que dichos módulos están acoplados a un árbol que gira mediante la acción de un motor. Existe un sistema de acoplamiento para cerdas (filamentos, bandas, tiras, segmentos o flecos) que permite su recambio sin necesidad de desmontar el eje de rotación o sin desmontar las piezas de acoplamiento y aplicable a cualquier máquina. Este sistema de acoplamiento es adecuado tanto para los cepillos giratorios de eje vertical como horizontal y se describe en el modelo de utilidad ES1187983U. At present, the rotating brushes for both vehicle washing machines and for other purposes comprise a succession of modules that support bristles, bands, strips or fringes, while said modules are coupled to a tree that rotates through the action of an engine There is a coupling system for bristles (filaments, bands, strips, segments or fringes) that allows its replacement without the need to disassemble the axis of rotation or without disassembling the coupling parts and applicable to any machine. This coupling system is suitable for both vertical and horizontal axis rotating brushes and is described in utility model ES1187983U.
La pieza de acoplamiento descrita en dicho modelo de utilidad corresponde a la pieza de acoplamiento descrita en la publicación ES1138658U, pero se han modificando los medios de sujeción para las cerdas o bandas. El sistema descrito en ES1138658U utiliza ganchos como medios para la sujeción de las cerdas o bandas, mientras que los medios sujeción en ES1187983U (ver Figura 1 ) son contrauñas (1 ) y una pieza rígida (2) a la que se acoplan las cerdas o bandas (3) mediante cosido del material de las bandas. La pieza rígida (2) se inserta en la contrauña (1) por presión, que permite la sustitución rápida de las cerdas sin desmontar la pieza de acoplamiento (4) del eje de rotación. The coupling part described in said utility model corresponds to the coupling part described in publication ES1138658U, but the fastening means for the bristles or bands have been modified. The system described in ES1138658U uses hooks as means for securing the bristles or bands, while the fastening means in ES1187983U (see Figure 1) are counter-nails (1) and a rigid part (2) to which the bristles are attached or bands (3) by sewing the material of the bands. The rigid part (2) is inserted into the counter-hole (1) by pressure, which allows the quick replacement of the bristles without disassembling the coupling part (4) from the rotation axis.
Sin embargo, el sistema de sujeción y las bandas descritas en el modelo de utilidad ES1187983U presenta los siguientes problemas, observados tras varias pruebas de uso: • Las piezas rígidas se rompen. However, the fastening system and the bands described in the utility model ES1187983U have the following problems, observed after several tests of use: • Rigid parts are broken.
• El eje de rotación soporta mucho más peso total, debido al incremento de peso de las cerdas o bandas. • The axis of rotation supports much more total weight, due to the increase in weight of the bristles or bands.
• Es costoso de coser. • It is expensive to sew.
Breve descripción de la Invención Brief Description of the Invention
Según un primer aspecto de la invención, se aporta una cerda o banda para ser montada en una pieza de acoplamiento de un cepillo giratorio, dicha cerda o banda comprendiendo: According to a first aspect of the invention, a bristle or band is provided to be mounted on a coupling piece of a rotating brush, said bristle or band comprising:
- un engrasamiento en un extremo de la cerda o banda, dicho engrasamiento se introduce mediante presión tras una uña o gancho de la pieza de acoplamiento para sujetar la banda a la pieza de acoplamiento, en uso; - a greasing at one end of the bristle or band, said greasing is introduced by pressure after a nail or hook of the coupling piece to attach the band to the coupling part, in use;
- una zona de refuerzo adyacente al engrasamiento; y - a reinforcement zone adjacent to the greasing; Y
- una zona de limpieza menos rígida que la zona de refuerzo, adyacente a la misma y situada al otro extremo donde está el engrasamiento. - a cleaning zone less rigid than the reinforcement zone, adjacent thereto and located at the other end where the greasing is.
Con una banda o cerda como la descrita anteriormente se consigue disminuir la Incidencia de roturas en las bandas o cerdas en comparación con los sistemas anteriores debido a que no existen zonas de tensiones locales elevadas cuando el cepillo giratorio está en funcionamiento, ya que se han eliminado los puntos de tensiones locales elevadas, como los ojales o las sujeciones mediante uñas, y se han sustituido por un engrasamiento que, al no presentar orificios o geometrías complicadas, no produce tensiones locales elevadas durante el lavado. La zona de refuerzo, con mayor rigidez que la zona de limpieza, permite que las bandas o cerdas adopten una geometría plana y parcialmente estirada en sentido radial cuando el cepillo está en reposo y por lo tanto, al comenzar el movimiento giratorio del cepillo, no se requiere tanto esfuerzo mecánico por parte del motor y del eje de rotación para que las cerdas o bandas del cepillo se estiren totalmente por la fuerza centrífuga, ya que la zona de refuerzo mantiene las bandas o cerdas parcialmente estiradas en sentido radial cuando el cepillo está en reposo. Otra ventaja es que la zona de refuerzo disminuye o elimina los latigazos de las bandas, sobre todo en los cepillos de eje horizontal, porque el cepillo empieza a girar desde una geometría de reposo más equilibrada respecto a la rotación en tomo a su eje, lo que a su vez produce una puesta en marcha más estable y con menos esfuerzos mecánicos en todo el sistema, desde el motor, pasando por el eje, la pieza de acoplamiento y las bandas o cerdas. El peso total de las cerdas es menor, porque se ha eliminado la pieza de plástico del modelo de utilidad ES1187983U y se ha sustituido por un engrasamiento y una zona de refuerzo más ligera, con lo que esto también ayuda a reducir los esfuerzos mecánicos y las roturas provocadas por los mismos. With a band or bristle like the one described above, the Incidence of breaks in the bands or bristles can be reduced compared to the previous systems because there are no high local tension zones when the rotating brush is in operation, since they have been eliminated high local tension points, such as eyelets or nail fasteners, and have been replaced by a greasing that, as it does not have complicated holes or geometries, does not produce high local tensions during washing. The reinforcement zone, with greater rigidity than the cleaning zone, allows the bands or bristles to adopt a flat and partially stretched geometry radially when the brush is at rest and therefore, at the beginning of the rotary movement of the brush, not Both mechanical effort by the motor and the rotation axis is required so that the bristles or bands of the brush are fully stretched by centrifugal force, since the reinforcement zone keeps the bands or bristles partially stretched radially when the brush is Resting. Another advantage is that the reinforcement zone decreases or eliminates the lashes of the bands, especially in the horizontal axis brushes, because the brush begins to rotate from a more balanced resting geometry with respect to the rotation in volume to its axis, which in turn produces a more stable start-up and with less mechanical stresses throughout the system, from the engine, through the shaft, the coupling piece and the bands or bristles. The total weight of the bristles is lower, because the plastic part of the utility model ES1187983U has been removed and replaced by a lighter greasing and reinforcement zone, which also helps reduce mechanical stresses and breaks caused by them.
Preferiblemente, las bandas o cerdas comprenden una franja flexible que actúa a modo de bisagra entre el engrasamiento y la zona de refuerzo con una rigidez menor que la zona de refuerzo. La franja flexible que actúa a modo de bisagra y que tiene una rigidez menor que la zona de refuerzo permite el movimiento adelante y atrás de las bandas o cerdas, sin acumulación de tensiones mecánicas en esa zona, y por lo tanto, sin producirse tantas roturas durante el lavado. Preferably, the bands or bristles comprise a flexible strip that acts as a hinge between the greasing and the reinforcement zone with a stiffness less than the reinforcement zone. The flexible strip that acts as a hinge and has a lower stiffness than the reinforcement zone allows the movement back and forth of the bands or bristles, without accumulation of mechanical stresses in that area, and therefore, without causing so many breaks during washing.
Preferiblemente, la zona de limpieza comprende un material textil flocado. Este tipo de materiales es muy adecuado porque produce unos resultados de limpieza en vehículos muy superiores a otros tipos de material textil o fibra. Preferably, the cleaning zone comprises a flocked textile material. This type of materials is very suitable because it produces cleaning results in vehicles far superior to other types of textile or fiber material.
Preferiblemente la banda o cerda comprende un material principal que se extiende a lo largo de toda la longitud de la banda. Esta es una característica muy deseable ya que al no presentar uniones en sentido longitudinal de la banda o cerda, ésta es capaz de resistir sin romperse o desmembrarse las fuerzas centrífugas durante en funcionamiento del cepillo giratorio. Preferably the band or bristle comprises a main material that extends along the entire length of the band. This is a very desirable feature since, as it does not have longitudinal joints of the band or sow, it is able to resist without breaking or dismembering the centrifugal forces during operation of the rotating brush.
Preferiblemente el material principal de la banda es un material textil flocado por al menos una cara. Preferably the main material of the band is a textile material flocked on at least one side.
Preferiblemente, el engrasamiento comprende un bucle longitudinal hecho con el material principal de la banda o cerda y cosido sobre sí mismo dentro del cual hay una varilla de refuerzo, preferiblemente con una longitud igual a la anchura de la banda o cerda. Este tipo de engrasamiento es muy fácil de fabricar ya que utiliza el material principal de la propia banda para realizar el bucle y tan solo se ha de aportar una varilla de refuerzo en el interior del bucle. La varilla de refuerzo aumenta la seguridad de la sujeción entre las bandas o cerdas y la pieza de acoplamiento, particularmente porque aumenta la resistencia mecánica del engrasamiento. Preferably, the greasing comprises a longitudinal loop made with the main material of the band or bristle and sewn on itself within which there is a reinforcing rod, preferably with a length equal to the width of the band or bristle. This type of greasing is very easy to manufacture since it uses the main material of the band itself to make the loop and only one reinforcement rod has to be provided inside the loop. The reinforcing rod increases the safety of the attachment between the bands or bristles and the coupling piece, particularly because it increases the mechanical strength of the greasing.
Preferiblemente, la varilla de refuerzo es flexible y no compresible. Esta característica es muy conveniente para las varillas de refuerzo porque permite extraer las varillas de refuerzo y desmontar las bandas de las piezas de acoplamiento y sustituirlas por otras nuevas sin tener que desmontar ningún elemento del cepillo giratorio. Esta ventaja es muy conveniente si se tiene que sustituir solo algunas bandas o cerdas. Además, al ser no compresible, la varilla de refuerzo impide que la banda o cerda se desacople de la pieza de acoplamiento debido a las fuerzas centrífugas durante el funcionamiento del cepillo. Preferably, the reinforcing rod is flexible and not compressible. This feature is very convenient for reinforcement rods because it allows the removal of reinforcement rods and Dismantle the bands of the coupling parts and replace them with new ones without having to disassemble any element of the rotating brush. This advantage is very convenient if you have to replace only some bands or bristles. In addition, being non-compressible, the reinforcing rod prevents the band or bristle from decoupling from the coupling part due to centrifugal forces during brush operation.
Preferiblemente, la franja flexible que actúa a modo de bisagra comprende el material principal de la banda. Preferably, the flexible strip acting as a hinge comprises the main material of the band.
Preferiblemente, la zona de refuerzo comprende una pieza de material flexible, de mayor rigidez que el material principal de la banda. Esta particular forma de realización de la zona de refuerzo es poco costosa ya que simplemente se une una pieza de refuerzo al material de la misma banda, bien sea mediante cosido, pegado, grapado etc. También se aporta un método de fabricación de una cerda o banda según el primer aspecto de la invención, dicho método comprendiendo los pasos de: Preferably, the reinforcement zone comprises a piece of flexible material, of greater rigidity than the main material of the band. This particular embodiment of the reinforcement zone is inexpensive since it simply joins a reinforcement piece to the material of the same band, either by sewing, gluing, stapling etc. A method of manufacturing a bristle or band according to the first aspect of the invention is also provided, said method comprising the steps of:
aportar una porción de material principal de la banda, de mayor longitud que la longitud final de la banda; provide a portion of the main material of the band, of greater length than the final length of the band;
colocar una pieza de material flexible, de mayor rigidez que el material principal de la banda sobre el material principal de la banda, cerca del centro de la banda; place a piece of flexible material, more rigid than the main material of the band on the main material of the band, near the center of the band;
doblar el material principal de la banda sobre sí mismo, cubriendo la pieza de material flexible con el material principal de la banda doblado sobre sí mismo; folding the main material of the band on itself, covering the piece of flexible material with the main material of the band folded on itself;
formar un bucle y coser el material principal de la banda para que quede el bucle en uno de los extremos de la banda formando un engrasamiento; form a loop and sew the main material of the band so that the loop is at one end of the band forming a greasing;
coser el material principal de la banda de forma que se agarre la pieza flexible al material principal de la banda; y sew the main material of the band so that the flexible piece is attached to the main material of the band; Y
