DESCRIPCIÓN DESCRIPTION
MÁQUINA PARA EL LAVADO DE BANDEJAS Objeto de la invención TRAY WASHING MACHINE Object of the invention
La presente invención se refiere a una máquina para el lavado de bandejas que tiene una configuración que permite incrementar el rendimiento de la máquina, sobre todo para asumir las exigencias de determinados centros de trabajo, aeropuertos, etc. Para ello se ha diseñado una nueva estructura soporte de las bandejas que permite higienizar varias bandejas a la vez, sin necesidad de modificar la morfología básica de la máquina. The present invention refers to a machine for washing trays that has a configuration that allows increasing the performance of the machine, especially to meet the demands of certain work centers, airports, etc. For this, a new tray support structure has been designed that allows several trays to be sanitized at the same time, without the need to modify the basic morphology of the machine.
Problema técnico a resolver y antecedentes de la invención Technical problem to be solved and background of the invention
En la actualidad el lavado de cestas y bandejas se realiza en general de forma manual, de manera que esta forma de lavado es cara y en algunos casos no es lo suficientemente eficiente y rápida. At present, the washing of baskets and trays is generally carried out manually, so that this form of washing is expensive and in some cases it is not efficient and fast enough.
No obstante también son conocidas las máquinas lavadoras rotativas de cestas y bandejas que comprenden un espacio interior donde se ubica una estructura soporte con medios de sujeción de la cesta/bandeja; donde dicha estructura soporte junto con la cesta/bandeja giran durante la fase de lavado mediante un elemento motor que transmite su movimiento giratorio a un eje conectado a la estructura soporte a través de un mecanismo de transmisión. La ubicación del elemento motor y el mecanismo de transmisión están ubicados en una zona de la máquina de difícil acceso, lo que dificulta el montaje y también el mantenimiento de la máquina. However, rotary washing machines for baskets and trays are also known that comprise an interior space where a support structure is located with means of holding the basket / tray; where said support structure together with the basket / tray rotate during the washing phase by means of a motor element that transmits its rotary movement to a shaft connected to the support structure through a transmission mechanism. The location of the motor element and the transmission mechanism are located in an area of the machine that is difficult to access, which makes the assembly and also the maintenance of the machine difficult.
Otro inconveniente de estas máquinas es que los medios de sujeción de la cesta/bandeja comprenden complejos dispositivos de anclaje que alargan en exceso el tiempo empleado para la sujeción de la cesta/bandeja; y además son dispositivos de anclaje poco flexibles y poco efectivos en el sentido de que particularmente resulta bastante dificultoso sujetar algunos modelos de cestas. Another drawback of these machines is that the means for securing the basket / tray comprise complex anchoring devices that excessively lengthen the time used to secure the basket / tray; Furthermore, they are not very flexible and ineffective anchoring devices in the sense that it is particularly difficult to hold some models of baskets.
El modelo de utilidad con n° de publicación en España ES 1199238 U es propiedad del titular de la invención que nos ocupa, y se refiere a una máquina para el lavado de accesorios que incluye una estructura soporte giratoria, donde dicha estructura soporte incluye medios para sujetar también los accesorios a lavar. The utility model with publication number in Spain ES 1199238 U is the property of the owner of the invention at hand, and refers to a machine for washing accessories that includes a rotating support structure, where said structure The holder includes means to also hold the accessories to be washed.
Dicha estructura soporte comprende un travesaño conectado a un eje frontal giratorio para transmitir el movimiento rotatorio al conjunto de la estructura soporte que sustenta los accesorios a lavar. Said support structure comprises a crossbar connected to a rotating front shaft to transmit the rotary movement to the whole of the support structure that supports the accessories to be washed.
La estructura soporte descrita en la máquina de dicho modelo de utilidad comprende además una base formada por dos soportes angulares que incluyen unas primeras ramas que se acoplan al travesaño, y unas segundas ramas sobre las que apoya el accesorio a lavar; donde los dos soportes angulares de la base tienen una primera regulación para poder variar su posicionamiento en altura en un plano sustancialmente vertical; y donde los soportes angulares de la base tienen una segunda regulación para poder variar la distancia entre los dos soportes angulares de la base en un plano sustancialmente horizontal. The support structure described in the machine of said utility model also comprises a base formed by two angular supports that include first branches that are coupled to the crossbar, and second branches on which the accessory to be washed rests; where the two angular supports of the base have a first adjustment to be able to vary their positioning in height in a substantially vertical plane; and where the angular supports of the base have a second adjustment to be able to vary the distance between the two angular supports of the base in a substantially horizontal plane.
Por otro lado cabe señalar que la creciente alarma por contagios de patógenos se materializa de forma especial en los aeropuertos, en los que miles de personas tocan las bandejas utilizadas en los controles de acceso, sin que dichas bandejas sean sometidas a procesos efectivos de higienizado. On the other hand, it should be noted that the growing alarm due to contagion of pathogens is materialized in a special way in airports, where thousands of people touch the trays used in access controls, without these trays being subjected to effective sanitizing processes.
Sólo si una máquina asegura un tratamiento rápido y un volumen de bandejas a tratar aceptable es posible atajar este problema de forma eficiente, de manera que la máquina de la invención va encaminada precisamente en esta línea. Only if a machine ensures rapid treatment and an acceptable volume of trays to be treated is it possible to tackle this problem efficiently, so that the machine of the invention is directed precisely in this line.

La máquina comprende además unos dispositivos de bloqueo, cada uno de los cuales está configurado para inmovilizar cada bandeja al primer bastidor; donde dicho dispositivo de bloqueo adopta una posición seleccionada entre una posición activa en la que se bloquea la extracción de la bandeja, y una posición inactiva en la que se libera la extracción de la bandeja para poder sacarla fuera de la estructura soporte, y para poder meterla dentro de dicha estructura soporte. The support structure comprises a first vertical frame, a second vertical frame, and several pairs of longitudinal guides including opposite ends that are fixed, respectively, to the first frame and the second frame; where the pairs of longitudinal guides are configured to couple the trays in parallel removably. The machine further comprises locking devices, each of which is configured to immobilize each tray to the first frame; where said locking device adopts a position selected between an active position in which the extraction of the tray is blocked, and an inactive position in which the extraction of the tray is released in order to be able to take it out of the support structure, and to be able to put it inside said support structure.
El primer bastidor comprende dos primeros perfiles colaterales paralelos y unos primeros perfiles transversales que están unidos perpendicularmente por sus extremos a los primeros perfiles colaterales; donde los dispositivos de bloqueo están fijados a los primeros perfiles transversales. The first frame comprises two first parallel collateral profiles and first transverse profiles that are attached perpendicularly at their ends to the first collateral profiles; where the locking devices are attached to the first cross sections.
El segundo bastidor comprende dos segundos perfiles colaterales paralelos y un segundo perfil transversal centrado que está unido por sus extremos a los segundos perfiles colaterales.

The assembly of the support structure is fixed in cantilever to a support integral to a front axis, by means of the second transverse profile that forms part of the second frame; where this fixation is secured by means of some screws and some nuts; and where the front shaft is configured to rotate and transmit its rotary movement to the support structure through the motor element.
Las guías longitudinales están unidas por unos de sus extremos a los extremos de los primeros perfiles transversales en coincidencia con unos huecos de los primeros perfiles colaterales del primer bastidor; donde en dichos huecos se ubican también unos extremos de los primeros perfiles transversales. The longitudinal guides are joined by one of their ends to the ends of the first transverse profiles in coincidence with some holes in the first collateral profiles of the first frame; where in said holes some ends of the first transverse profiles are also located.
En cambio los otros extremos parejos de las guías longitudinales están unidos a los segundos perfiles colaterales del segundo bastidor mediante unas cartelas angulares. Cada dispositivo de bloqueo comprende un tirador, una pletina de retención, un resorte y una tuerca. El tirador comprende una cabeza, una porción cilindrica y una porción roscada de menor diámetro que la porción cilindrica, donde la porción cilindrica está ubicada entre la cabeza y la porción roscada. On the other hand, the other even ends of the longitudinal guides are joined to the second collateral profiles of the second frame by means of angular brackets. Each locking device comprises a handle, a retaining plate, a spring, and a nut. The puller comprises a head, a cylindrical portion and a threaded portion of a smaller diameter than the cylindrical portion, where the cylindrical portion is located between the head and the threaded portion.
Un primer tramo de dicha tercera porción roscada encaja dentro de un orificio pasante ubicado en el centro del primer perfil transversal del primer bastidor, mientras que un segundo tramo de dicha tercera porción roscada asoma por dentro de un espacio interior de la estructura soporte; donde alrededor de dicho segundo tramo está acoplado el resorte retenido axialmente por un primer extremo en el propio primer perfil transversal, mientras que un segundo extremo del resorte, opuesto al primer extremo, está retenido contra la tuerca acoplada en la porción roscada del tirador. A first section of said third threaded portion fits into a through hole located in the center of the first transverse profile of the first frame, while a second section of said third threaded portion protrudes from inside an interior space of the support structure; where around said second section the spring retained axially by a first end in the first transverse profile itself is engaged, while a second end of the spring, opposite the first end, is retained against the nut engaged in the threaded portion of the knob.
La pletina de retención está acoplada sobre una parte inicial de la porción roscada del tirador, a la vez que está en contacto con una superficie frontal del primer perfil transversal perteneciente al primer bastidor. The retaining plate is engaged on an initial part of the threaded portion of the handle, while it is in contact with a front surface of the first transverse profile belonging to the first frame.
La pletina de retención incluye un orificio en el que encaja la parte inicial de la porción roscada del tirador; donde dicha pletina de retención posee un acodamiento extremo sobre el que hace tope una porción del saliente perimetral de la bandeja cuando está colocada sobre el correspondiente par de guías longitudinales.

The assembly of the support structure 3 is fixed cantilever to the support 18 integral with the front axle 6, by means of the second transverse profile 8b that forms part of the second frame 8; where this fixing is secured by means of screws 16a and nuts 16b.
Las guías longitudinales 9 están unidas por unos de sus extremos a los extremos de los primeros perfiles transversales 7b en coincidencia con unos huecos 17 de los primeros perfiles colaterales 7a del primer bastidor 7; donde en dichos huecos 17 se ubican también unos extremos de los primeros perfiles transversales 7b. The longitudinal guides 9 are joined by one of their ends to the ends of the first transverse profiles 7b in coincidence with recesses 17 of the first collateral profiles 7a of the first frame 7; where in said holes 17 some ends of the first transverse profiles 7b are also located.
En cambio los otros extremos de las guías longitudinales 9 están unidos a los segundos perfiles colaterales 7b del segundo bastidor 8 mediante unas cartelas angulares 10. On the other hand, the other ends of the longitudinal guides 9 are joined to the second collateral profiles 7b of the second frame 8 by means of angular brackets 10.
Cada dispositivo de bloqueo 4 comprende un tirador 11, una pletina de retención 12, un resorte 13 y una tuerca 14. Each locking device 4 comprises a handle 11, a retention plate 12, a spring 13 and a nut 14.
El tirador 11 comprende una cabeza 11a, una porción cilindrica 11b y una porción roscada 11c de menor diámetro que la porción cilindrica 11b; donde la porción cilindrica 11b está ubicada entre la cabeza 11a y la porción roscada 11c. The handle 11 comprises a head 11a, a cylindrical portion 11b and a threaded portion 11c of a smaller diameter than the cylindrical portion 11b; where the cylindrical portion 11b is located between the head 11a and the threaded portion 11c.
Un primer tramo de dicha tercera porción roscada 11c encaja dentro de un orificio pasante 15 ubicado en el centro del primer perfil transversal 7b, mientras que un segundo tramo de dicha tercera porción roscada 5c asoma por dentro de un espacio interior de la estructura soporte 3, de forma que alrededor de dicho segundo tramo está acoplado el resorte 13 retenido axialmente por un primer extremo en el propio primer perfil transversal 7b, mientras que un segundo extremo del resorte 13 opuesto al primer extremo está retenido contra la tuerca 14 acoplada en la porción roscada 11c del tirador 11. A first section of said third threaded portion 11c fits inside a through hole 15 located in the center of the first transverse profile 7b, while a second section of said third threaded portion 5c protrudes from inside an interior space of the support structure 3, in such a way that around said second section the spring 13 retained axially by a first end in the first transverse profile 7b itself is coupled, while a second end of the spring 13 opposite the first end is retained against the nut 14 coupled in the threaded portion 11c from shooter 11.
La pletina de retención 12 está acoplada en sobre una parte inicial de la porción roscada 11c, a la vez que está en contacto con una superficie frontal del primer perfil transversal 7b. Para ello dicha pletina de retención 12 incluye un orificio en el que encaja la parte inicial de la porción roscada 11c. Además, dicha pletina de retención 12 posee un acodamiento extremo 12a sobre el que hace tope una porción del saliente perimetral de la bandeja 1 cuando está colocada sobre el correspondiente par de guías longitudinales 9. The retaining plate 12 is engaged on an initial part of the threaded portion 11c, while being in contact with a front surface of the first transverse profile 7b. For this, said retention plate 12 includes a hole in which the initial part of the threaded portion 11c fits. Furthermore, said retention plate 12 has an end bend 12a on which a portion of the projection abuts perimeter of the tray 1 when it is placed on the corresponding pair of longitudinal guides 9.
Cuando cada bandeja 1 está colocada dentro de la estructura soporte 3, dicha bandeja 1 está retenida por la pletina de retención 12 y por los segundos perfiles colaterales 8a del segundo bastidor 8, sobre los que hace tope unas zonas del contorno saliente perimetral When each tray 1 is placed inside the support structure 3, said tray 1 is retained by the retention plate 12 and by the second collateral profiles 8a of the second frame 8, on which some areas of the perimeter protruding contour abut
Para poder extraer cada bandeja 1 del espacio interior de la estructura soporte 3 y/o para introducirla dentro, es necesario colocar la pletina de retención 12 en una posición angular alrededor del tirador 11 en la que no interceda con la extracción o introducción de la bandeja 1. Para ello se tira hacia fuera de dicho tirador 11 en contra de la resistencia del resorte 13 y se coloca la pletina de retención 12 en la posición angular requerida. In order to be able to extract each tray 1 from the interior space of the support structure 3 and / or to insert it inside, it is necessary to place the retention plate 12 in an angular position around the handle 11 in which it does not intercede with the extraction or insertion of the tray. 1. To do this, said handle 11 is pulled out against the resistance of the spring 13 and the retention plate 12 is placed in the required angular position.
Por otro lado, una vez introducida la bandeja 1 dentro de la estructura soporte 3, se procede a actuar sobre la pletina de retención 12 de la misma forma que se ha descrito en el párrafo anterior, pero ahora se gira la pletina de retención 12 hasta que su acodamiento extremo se enfrenta al contorno saliente perimetral de la bandeja 1 para evitar su extracción. On the other hand, once the tray 1 has been inserted into the support structure 3, the retention plate 12 is operated in the same way as described in the previous paragraph, but now the retention plate 12 is rotated until that its extreme bending faces the perimeter protruding contour of the tray 1 to prevent its extraction.
Como vemos se trata de una estructura soporte 3 que incluye los dos bastidores 7, 8 verticales adaptables a la máquina dotada de varias parejas de guías longitudinales 9 ubicadas entre dichos bastidores 7, 8 y dispuestas verticalmente a diferentes alturas regulables para acoger varias bandejas 1 , de manera que la distancia en vertical entre ellas permita compensar la profundidad máxima de las bandejas 1 asegurándose que sus fondos quedan perfectamente expuestos a los medios de limpieza. As we can see, it is a support structure 3 that includes the two vertical frames 7, 8 adaptable to the machine equipped with several pairs of longitudinal guides 9 located between said frames 7, 8 and arranged vertically at different adjustable heights to accommodate several trays 1, so that the vertical distance between them makes it possible to compensate for the maximum depth of the trays 1, ensuring that their bottoms are perfectly exposed to the cleaning means.
Frontalmente cada primer perfil transversal 7b une los extremos delanteros de cada pareja de guías longitudinales 9 y da cabida a un dispositivo de bloqueo 4 que está asociado al contorno saliente perimetral de la bandeja 1 para mantenerla estable en su ubicación durante todo el proceso de limpieza. Frontally, each first transverse profile 7b joins the front ends of each pair of longitudinal guides 9 and accommodates a locking device 4 that is associated with the perimeter projecting contour of the tray 1 to keep it stable in its location throughout the cleaning process.
Cabe señalar que la distancia vertical entre parejas de guías longitudinales 9 es regulable, con lo cual es posible adaptar otros accesorios al tratamiento de bandejas con profundidades diferentes. It should be noted that the vertical distance between pairs of longitudinal guides 9 is adjustable, with which it is possible to adapt other accessories to the treatment of trays with different depths.
Para poder llevar a cabo la regulación de la distancia vertical entre los diferentes pares de guías longitudinales 9, en una realización de la invención el primer bastidor 7 y el segundo bastidor 8 incluyen una multitud de orificios roscados para poder fijar a diferentes alturas, respectivamente, los primeros perfiles transversales 7b y las cartelas angulares 10, y obviamente las alturas de las guías longitudinales 9 que están fijadas a los dos bastidores 7, 8 por mediación de dichos primeros perfiles transversales 7b y dichas cartelas angulares 10. In order to carry out the regulation of the vertical distance between the different pairs of longitudinal guides 9, in an embodiment of the invention the first frame 7 and the second frame 8 include a multitude of threaded holes to be able to fix at different heights, respectively, the first transverse profiles 7b and the angular brackets 10, and obviously the heights of the longitudinal guides 9 that are fixed to the two frames 7, 8 by means of said first transverse profiles 7b and said angular brackets 10.
