Definitions
- the present invention refers to a system for the protection of luggage, which is based on the thermal effect on the thermo-shrinking polyethylene material 1 by restraining the retraction of this around the luggage in order to provide an external protection before scratches, stains and dirt, and any other deterioration that is produced by possible improper manipulations.
- This wrap protects the luggage against scratches and other damages that can be caused by shocks and blows to the luggage, and once arrived at the destination the wrap is broken leaving the luggage free of signs, stickers and damages available to the traveler.
- the system for the protection of luggage here recommended, consists, therefore, in the use of bags of thermo-shrinkable polyethylene material, available in the current market, which serve to introduce luggage in them. Said material when placed under special thermal effects and for a defined period of time undergoes retraction in such a way that when it shrinks it covers the luggage, providing a complete and closed covering.
- Said oven consists of a configuration cabin Prismatic-rectangular whose roof, bottom and side walls constitute a double layer structure of metallic sheets carrying a thermal insulating material (for example fiberglass) between both layers.
- the thickness of the thermal insulating material is greater than at the bottom.
- the need for this construction arises from the fact that hot air in any space always tends to rise, resulting in a greater probability of temperature losses in the upper parts of the oven.
- the front face of the oven does not have metal sheets to provide luggage access. This front face has a curtain of thermal insulating material to prevent hot air from escaping and thus prevent temperature loss.
- the rear face of the oven can be closed with metal sheets in the same way as the side walls, or be opened with a curtain to provide a second access. In the latter case, the front face would serve as the entrance and the rear as the luggage exit for cases where a faster operation is desired.
- the internal temperature of the furnace necessary for the retraction of polyethylene is produced by the use of a battery of electrical resistors commanded from an electrical control panel in turn connected with a thermostat that serves to set and maintain the appropriate temperature, which it will have to be established according to the thickness of the plastic material, and the residence time, of the product inside the oven, varying in the practical cases the first between 200 and 260 s ⁇ and the second between 15 and 45 seconds.
- this system has a transport mechanism that can be carried out by either of the following two options:
- the conveyor is constituted by a motionless structure which has a horizontal movement mechanism either by means of a conveyor belt which can be made with steel mesh, or with siliconized fabric or by means of metal rods or tubes arranged in parallel in such a way. which form a continuous grid-like line that in the same way that the conveyor belt can move the luggage horizontally in or out of the oven.
- the second option consists of a mobile conveyor that can move into the oven and vice versa, introducing or removing (in the case of the oven with a single access) with its movements the luggage that it carries.
- the conveyors have a proximity detector installed on the edge of the conveyor line to detect the placement of luggage (wrapped in plastic bags) on top of the conveyor.
- luggage travel is initiated by means of the relevant electronic signals that are emitted from the electronic control and control panel.
- the luggage is thus introduced into the oven whose temperature is preset. After the time required for heat shrinkage, the electronic control panel starts the conveyor again, this time in the opposite direction, to remove the luggage already covered by the heat shrinkable material from the oven. In the case of having an entrance and an exit, said transporter would advance in a single direction (from the entrance to the exit).

- Figure 2 is a view of the interior of the oven sectioned by a vertical plane.
- Figure 3 represents a perspective view of an embodiment of the conveyor by means of a continuous belt.
- Figure 4 represents a perspective view of an embodiment of the conveyor by a continuous line formed by metal tubes.
- Figure 5 represents a perspective view of a baggage protection machine made with a mobile conveyor.
- the luggage protection system consists of an oven (1) (see figures 1 and 2), inside of which there are electric resistance batteries (2) intended to heat the air inside the oven (1).
- the fan (3) also installed inside the oven (1) is dedicated to produce, with its operation, an air movement, in order to provide a homogeneous temperature inside the oven (i), necessary for retraction of the bag of heat shrinkable polyethylene material (4), wrapped around luggage (5).
- the roof, the bottom and the side walls of the furnace (1) constitute a double layer structure of metal sheets (£) carrying between them a thermal insulating material (7) (for example fiberglass).
- the thickness of the insulating material (7), and therefore the distance between each pair of facing walls (6) is greater in the ceiling (a) of the oven than in the side walls (b), and in these are larger than in the bottom (c) (see figure 2).
- the front face (S) of the oven (1) serves as access for the entry and exit of luggage. Said face ( ⁇ ) is covered by a curtain of thermal insulating material and is intended to prevent the release of hot air and thus avoid the loss of temperature inside the oven (1).
- the temperature inside the oven (1) is controlled by a thermostat (9) in connection with an electronic control and control panel (10). In this way the temperature inside the oven is maintained at the preset value.
- the electronic control and control panel is responsible for governing all automatic system operations.
- the mechanism for transporting luggage in and out of the oven can be carried out in several manual and automatic ways. In this section of practical realization two preferential options will be presented.
- Option 1a In this case it is a conveyor (11) fixed in position (see figure 3), which is used to move the luggage by moving a conveyor belt (for example metal mesh), arranged horizontally and actuated by means of the rotating movement of two rollers (13) which in turn are driven by a gearmotor (14).
- a continuous line can be used (see figure 4) based on a structure composed of tubes (15) of material resistant to the heat, arranged in parallel and joined perpendicularly each at both ends with two metal chains (16). each of said chains forms a continuous band around two sprockets or sprockets (17).
- Each pair of facing sprockets each belonging to a different continuous chain, revolves around an axis (18) that joins them and is dedicated to transmitting the rotating movement of the geared motor (14) to the sprockets (17) and therefore to the conveyor mechanism
- Option 2 ⁇ In this option (see figure 5), it is a mobile conveyor (19), on which the luggage (5) wrapped in the bag of heat shrinkable material (4) is placed.
- the luggage remains without movement relative to the conveyor (19), however the horizontal displacement of the latter arranged in or out of the cabin (20), results in the introduction of the luggage (4) in the oven (1) or its extraction from him.
- This conveyor is composed of a hollow structure with a prismatic-rectangular configuration whose upper horizontal vertices (21) are shaped like zippers with their serrated faces facing down. Said zippers are geared with two sprockets or sprockets (22).
- This conveyor presents on its upper face, that is, where the luggage is placed, a structure by way of grid constructed using a series of metal rods or tubes (24) or any heat-resistant material, arranged in parallel and in a horizontal position with the ends of each fixed jointly on the zippers (21).
- All the conveyor options described herein have their respective proximity detectors (25) capable of detecting the placement or not of the luggage on the conveyor. Said detectors are electrically connected to the electronic control and control panel (10). Once the luggage is placed on the conveyor, the proximity detector (25) sends the detection signal to the control and control panel (10), and this in turn drives the electric motor, resulting in the movement of luggage (4 ) into the oven.

Abstract
System for the protection of luggage of passengers, based on the thermal effect on thermal retractable polyethylene material resulting in the retraction of the latter around the luggage in order to confer external protection against inproper handling. The thermal effect is produced by means of an oven (1) inside which are provided a bank of resistors (2), a fan (3) and a thermal switch (9). The operation of the system is controlled by a command and control electronic panel (10). The system may either have a single access (8) which will be used for the introduction and removal of the luggage or two access, a front access for the introduction and a rear access for the exit of the luggage. The system is also comprised of optional transport mechanisms like a fixed conveyor (11) embodied by a continuous belt with horizontal motion or like a movable conveyor (19) whose horizontal motion causes the displacement of the luggage. In either case, the conveyor is provided with a proximity sensor (25).
Description
Sistema para la protección de equipajes. Baggage protection system.
La presente invención, como su título indica, se refiere a un sistema para la protección de equipajes, el cual se basa en el efecto térmico sobre el material polietileno termorretracti 1 resutando la retración de éste en torno al equipaje a fin de proporciónale una protección externa ante rayaduras, manchas y suciedades, y cualquier otro deterioro que se produzca por posibles manipulaciones indebidas. The present invention, as its title indicates, refers to a system for the protection of luggage, which is based on the thermal effect on the thermo-shrinking polyethylene material 1 by restraining the retraction of this around the luggage in order to provide an external protection before scratches, stains and dirt, and any other deterioration that is produced by possible improper manipulations.
Como bien se sabe, los equipajes de los viajeros o cualquier otro paquete o bulto de tamaflo relativamente grande que tenga que ser desplazado de un lugar a otro mediante transportes públicos, quedan retirados de la disposición de sus propietarios, siendo dirigidos a compartimentos o cuartos destinados al almacenamiento de los mismos. En los aeropuertos, a la hora de facturar y embarcar, se colocan etiquetas y pegatinas y otras señales sobre las maletas que posteriormente resultan difíciles de quitar. Asimismo, los equipajes atraviesan un considerable camino sobre transportadores automáticos para ser después almacenados en el avión. Este tipo de transportadores produce en ocasiones rayaduras e incluso roturas en las maletas por los choques causados en las mismas o entre éstas y las paredes de las líneas transportadoras. LOS autobuses disponen de compartimentos en los que se introducen los equipajes de viajeros. Dichos compartimentos ofrecen un espacio limitado, por lo que en el caso de que se trate de equipajes numerosos, éstos tendrán que colocarse uno encima del otro con las consigueintes posibilidades de deterioro, rayadura o rotura que se
producirían por los golpes y choques ocasionados entre lasmaletas. As is well known, the luggage of travelers or any other package or package of relatively large size that has to be moved from one place to another by public transport, are removed from the disposal of their owners, being directed to compartments or rooms intended to the storage of them. At airports, when checking in and boarding, labels and stickers and other signs are placed on suitcases that are later difficult to remove. Likewise, the luggage crosses a considerable road on automatic transporters to be later stored in the plane. This type of conveyor sometimes causes scratches and even breaks in the suitcases due to the collisions caused in them or between them and the walls of the conveyor lines. THE buses have compartments in which passenger luggage is introduced. These compartments offer a limited space, so in the case of numerous luggage, they will have to be placed on top of each other with the possible possibilities of deterioration, scratch or breakage they would produce by the blows and shocks caused between the tapes.
Hasta la actualidad no se conoce sistema alguno para paliar los problemas arriba expuestos, por lo que el sistema para la protección de equipajes objeto de la presente invención, puede considerarse como una novedad en este aspecto. Dicho sistema ofrece la protección de los equipajes mediante una envoltura de material plástico y de tipo transparente y susceptible a retracción bajo efectos térmicos, recubriendo por tanto la totalidad del equipaje, al mismo tiempo que permite la colocación sobre si mismo de las pegatinas, etiquetas y todo tipo de señales de rigor. Until now, there is no known system to alleviate the above problems, so the system for the protection of luggage object of the present invention can be considered as a novelty in this aspect. This system offers the protection of the luggage by means of a plastic wrap and of transparent type and susceptible to shrinkage under thermal effects, thus covering all the luggage, at the same time allowing the placement of stickers, labels and All kinds of signs of rigor.
Esta envoltura protege el equipaje ante rayaduras y otros desperfectos que pueden ocasionarse por choques y golpes al equipaje, y una vez llegado al destino la envoltura se rompe dejando al equipaje libre de señales, pegatinas y desperfectos a la disposición del viajero. This wrap protects the luggage against scratches and other damages that can be caused by shocks and blows to the luggage, and once arrived at the destination the wrap is broken leaving the luggage free of signs, stickers and damages available to the traveler.
El sistema para la protección de equipajes, aquí preconizado, consiste por lo tanto, en la utilización de bolsas de material de polietileno termorretráctil, disponibles en el mercado actual, que sirven para que se introduzcan en ellas el equipaje. Dicho material al ser puesto bajo efectos térmicos especiales y por un período de teimpo definido sufre retracción de tal manera que al encojerse cubre el equipaje, proporcionando un recubrimiento completo y cerrado. The system for the protection of luggage, here recommended, consists, therefore, in the use of bags of thermo-shrinkable polyethylene material, available in the current market, which serve to introduce luggage in them. Said material when placed under special thermal effects and for a defined period of time undergoes retraction in such a way that when it shrinks it covers the luggage, providing a complete and closed covering.
Para proporcional el efecto térmico, se ha ideado un horno diseñado especialmente para este fin. Dicho horno consiste en un habitáculo de configuración
prismático-rectangular cuyo techo, fondo y paredes laterales constituyen una estructura de doble capa de láminas metálica llevando un material aislante térmico (por ejemplo fibra de vidrio) entre ambas capas. El espesor del material aislante térmico es mayor que en el fondo. La necesidad de esta construcción surge del hecho de que el aire caliente en cualquier espacio, tiende siempre a ascender, resultando en mayor probabilidad de pérdidas de temperatura en las partes superiores del horno. La cara frontal del horno no tiene láminas metálicas para porporcionar el acceso del equipaje. Esta cara frontal cuenta con una cortina de material aislante térmico para impedir la salida del aire caliente y evitar así la pérdida de la temperatura. La cara posterior del horno puede ser cerrada con láminas metálicas de igual modo que las paredes laterales, o bien ser abierta con una cortina para proporcionar un segundo acceso. En este último caso la cara frontal serviría como la entrada y la posterior como la salida del equipaje para los casos en que se desee una operación más rápida. To provide the thermal effect, an oven designed especially for this purpose has been devised. Said oven consists of a configuration cabin Prismatic-rectangular whose roof, bottom and side walls constitute a double layer structure of metallic sheets carrying a thermal insulating material (for example fiberglass) between both layers. The thickness of the thermal insulating material is greater than at the bottom. The need for this construction arises from the fact that hot air in any space always tends to rise, resulting in a greater probability of temperature losses in the upper parts of the oven. The front face of the oven does not have metal sheets to provide luggage access. This front face has a curtain of thermal insulating material to prevent hot air from escaping and thus prevent temperature loss. The rear face of the oven can be closed with metal sheets in the same way as the side walls, or be opened with a curtain to provide a second access. In the latter case, the front face would serve as the entrance and the rear as the luggage exit for cases where a faster operation is desired.
La temperatura interna del horno necesaria para la retracción del polietileno, se produce mediante el uso de una batería de resistencias eléctricas comandadas desde un cuadro de mando eléctrico en conexión a su vez con un termostato que sirve para fijar y mantener la temperatura adecuada, la cual se tendrá que establecer según el espesor del material plástico, y el tiempo de permanencia, del producto en el interior del horno, variando en los casos prácticos la primera entre 200 y 260 sσ y la segunda entre 15 y 45 segundos. The internal temperature of the furnace necessary for the retraction of polyethylene is produced by the use of a battery of electrical resistors commanded from an electrical control panel in turn connected with a thermostat that serves to set and maintain the appropriate temperature, which it will have to be established according to the thickness of the plastic material, and the residence time, of the product inside the oven, varying in the practical cases the first between 200 and 260 sσ and the second between 15 and 45 seconds.
Dichas resistencias, una vez puestas en funcionamiento, calientan el aire interior del horno ejerciendo así el efecto términco sobre el material plástico. Para que el efecto de termorretracción sea
homogénero en todas las partes del material plástico que recubre el equipaje, se hace uso de un ventilador que se colocaría en el interior del horno, adosado a una pared cualquiera del mismo. El funcionamiento del ventilador porporciona el movimiento de aire caliente en el interior del horno resultando en una temperatura homogénera en el interior del mismo. These resistances, once put into operation, heat the interior air of the oven thus exerting the thermal effect on the plastic material. So that the heat shrinkage effect is homogeneous in all parts of the plastic material that covers the luggage, a fan is used that would be placed inside the oven, attached to any wall thereof. The operation of the fan provides the movement of hot air inside the oven resulting in a homogeneous temperature inside the oven.
Para introducir el equipaje, este sistema cuenta con un mecanismo transportador cuya realización puede efectuarse mediante cualquiera de las dos opciones siguientes: To enter the luggage, this system has a transport mechanism that can be carried out by either of the following two options:
Transportador fijo en el desplazamiento del equipaje: Fixed conveyor in the movement of luggage:
En este caso, el transportador está constituido por una estructura inmóvil la cual dispone de un mecanismo de desplazamiento horizontal bien mediante cinta transportadora la cual puede realizarse con malla de acero, o con tela siliconada o bien mediante varillas o tubos metálicos dispuestos paralelamente de tal modo que conforman una línea continua a modo de rejilla que de la misma manera que la cinta transportadora puede desplazar horizontalmente el equipaje hacia dentro o hacia fuera del horno. In this case, the conveyor is constituted by a motionless structure which has a horizontal movement mechanism either by means of a conveyor belt which can be made with steel mesh, or with siliconized fabric or by means of metal rods or tubes arranged in parallel in such a way. which form a continuous grid-like line that in the same way that the conveyor belt can move the luggage horizontally in or out of the oven.
La segunda opción consiste en un transportador móvil que puede desplazarse hacia el interior del horno y viceversa, introduciendo o extrayendo (en el caso del horno con un solo acceso) con sus desplazamientos el equipaje que lleva encima. The second option consists of a mobile conveyor that can move into the oven and vice versa, introducing or removing (in the case of the oven with a single access) with its movements the luggage that it carries.
En ambas opciones, los transportadores cuentan ccr¡ un detector de proximidad instalado en el borde de la línea transportadora para detectar la colocación del equipaje
(envuelto en bolsas de plástico) encima del transportador. In both options, the conveyors have a proximity detector installed on the edge of the conveyor line to detect the placement of luggage (wrapped in plastic bags) on top of the conveyor.
Una vez detectada la colocación, se inicia el desplazamiento del equipaje por medio de las señales electrónicas pertinentes que se emiten desde el cuadro electrónico de mando y control. Once the placement has been detected, luggage travel is initiated by means of the relevant electronic signals that are emitted from the electronic control and control panel.
El equipaje se introduce así en el horno cuya temperatura está prefijada. Tras el transcurso del tiempo necesario para la termorretracción, el cuadro electrónico de mando pone de nuevo en marcha el transportador, esta vez en dirección contraria, para extraer del horno el equipaje ya encubierto por el material termoretráctil . En el caso de tener una entrada y una salida, dicho transportador avanzaría en una única dirección (de la entrada a la salida). The luggage is thus introduced into the oven whose temperature is preset. After the time required for heat shrinkage, the electronic control panel starts the conveyor again, this time in the opposite direction, to remove the luggage already covered by the heat shrinkable material from the oven. In the case of having an entrance and an exit, said transporter would advance in a single direction (from the entrance to the exit).
Para comprender mejor el objeto de la presente invención, se presenta a continuación una realización práctica preferencial de la. misma con la ayuda de los planos anexos en los que: la figura 1 representa una vista en perspectiva de la máquina para la protección del equipaje. To better understand the object of the present invention, a preferred practical embodiment of the following is presented below. same with the help of the attached drawings in which: Figure 1 represents a perspective view of the machine for luggage protection.
La figura 2 es una vista del interior del horno seccionado por un plano vertical. Figure 2 is a view of the interior of the oven sectioned by a vertical plane.
La figura 3 representa una vista en perspectiva de un modo de realización del transportador mediante una cinta continua. Figure 3 represents a perspective view of an embodiment of the conveyor by means of a continuous belt.
La figura 4 representa una vista en perspectiva de un modo de realización del transportador mediante una línea continua conformada mediante tubos metálicos.
La figura 5 representa una vista en perspectiva de una máquina para la protección de equipajes realizada con un transportador móvil. Por razones de simplificación y evitar repeticiones, se procede aquí a describir un ejemplo de realización práctica del sistema en base a un horno con un único acceso de entrada y salida con sus respectivas opciones de transportadores, quedando siempre evidente que esta descripción no excluye la protección que se desea obtener para el caso de que el horno comprenda dos accesos, uno frontal para la entrada del equipaje y el otro posterior para la salida del mismo; caso en el que el mecanismo de transporte comprende las mismas estructuras que se describen a continuación satisfaciendo siempre las exigencias especiales de sus propios casos. Figure 4 represents a perspective view of an embodiment of the conveyor by a continuous line formed by metal tubes. Figure 5 represents a perspective view of a baggage protection machine made with a mobile conveyor. For reasons of simplification and avoiding repetition, we proceed to describe an example of practical implementation of the system based on a furnace with a single entry and exit access with their respective conveyor options, it is always evident that this description does not exclude protection that it is desired to obtain in the event that the oven comprises two accesses, one front for the entry of the luggage and the other one for the exit of the same; case in which the transport mechanism comprises the same structures described below, always satisfying the special requirements of their own cases.
El sistema para la protección de equipajes consiste en un horno (1) (ver figuras 1 y 2), en cuyo interior se encuentran baterías de resistencia eléctrica (2) destinadas a calentar el aire en el interior del horno (1). El ventilador (3), también instalado en el interior del horno (1) se dedica a producir, con su funcionamiento, un movimiento de aire, a fin de proporcionar una temperatura homogénea en el interior del horno (i), necesaria para la retracción de la bolsa de material polietileno termorretráctil (4), envuelta en torno al equipaje (5). The luggage protection system consists of an oven (1) (see figures 1 and 2), inside of which there are electric resistance batteries (2) intended to heat the air inside the oven (1). The fan (3), also installed inside the oven (1) is dedicated to produce, with its operation, an air movement, in order to provide a homogeneous temperature inside the oven (i), necessary for retraction of the bag of heat shrinkable polyethylene material (4), wrapped around luggage (5).
El techo, el fondo y las paredes laterales del horno (1), constituyen una estructura de doble capa de láminas metálicas (£) llevando entre ambas un material aislante térmico (7) (por ejemplo de fibra de vidrio). El espesor del material aislante (7), y por tanto la distancia entre cada par de paredes enfrentadas (6) es mayor en el techo (a) del horno que en las paredes laterales (b), y en
éstas mayores que en el fondo (c) (ver figura 2). The roof, the bottom and the side walls of the furnace (1), constitute a double layer structure of metal sheets (£) carrying between them a thermal insulating material (7) (for example fiberglass). The thickness of the insulating material (7), and therefore the distance between each pair of facing walls (6) is greater in the ceiling (a) of the oven than in the side walls (b), and in these are larger than in the bottom (c) (see figure 2).
La cara frontal (S) del horno (1) sirve de acceso para la entrada y salida de equipaje. Dicha cara (δ) está cubierta mediante una cortina de material aislante térmico y esté destinada a impedir la salida del aire caliente y evitar así la pérdida de temperatura en el interior del horno (1). La temperatura en el interior del horno (1) se controla mediante un termostato (9) en conexión con un cuadro electrónico de mando y control (10). De esta forma la temperatura en el interior del horno se mantiene en el valor preestablecido. The front face (S) of the oven (1) serves as access for the entry and exit of luggage. Said face (δ) is covered by a curtain of thermal insulating material and is intended to prevent the release of hot air and thus avoid the loss of temperature inside the oven (1). The temperature inside the oven (1) is controlled by a thermostat (9) in connection with an electronic control and control panel (10). In this way the temperature inside the oven is maintained at the preset value.
El cuadro electrónico de mando y control es el encargado de gobernar todos los funcionamientos automáticos del sistema. como se ha mencionado anteriormente, el mecanismo de transporte del equipaje hacia dentro y hacia fuera del horno puede realizarse en varias formas tanto manuales como automáticas. En este apartado de realización práctica se expondrán dos opciones preferenciales. The electronic control and control panel is responsible for governing all automatic system operations. As mentioned above, the mechanism for transporting luggage in and out of the oven can be carried out in several manual and automatic ways. In this section of practical realization two preferential options will be presented.
Opción 1a: En este caso se trata de un transportador (11) fijo en su posición (ver figura 3), el cual se dedica a desplazar el equipaje mediante el movimiento de una cinta transportadora (por ejemplo malla metálica), dispuesta horizontalmente y accionada mediante el movimiento giratorio de sendos rodillos (13) los cuales a su vez son accionados mediante un motorreductor (14). En esta opción, en lugar de la mencionada cinta continua se puede hacer uso de una línea continua (ver figura 4) basada en una estructura compuesta por tubos (15) de material resitente al
calor, dispuestos paralelamente y unidos perpendicularmente cada uno en ambos extremos con sendas cadenas metálicas (16). cada una de dichas cadenas forma una banda continua entorno a sendos piñones o ruedas dentadas (17). Cada par de piñones enfrentados, pertenecientes cada uno a una cadena continua distinta, gira en torno a un eje (18) que les une y se dedica a transmitir el movimiento giratorio del motorreductor (14) a los piñones (17) y por tanto al mecanismo transportador. Option 1a: In this case it is a conveyor (11) fixed in position (see figure 3), which is used to move the luggage by moving a conveyor belt (for example metal mesh), arranged horizontally and actuated by means of the rotating movement of two rollers (13) which in turn are driven by a gearmotor (14). In this option, instead of the mentioned continuous belt, a continuous line can be used (see figure 4) based on a structure composed of tubes (15) of material resistant to the heat, arranged in parallel and joined perpendicularly each at both ends with two metal chains (16). each of said chains forms a continuous band around two sprockets or sprockets (17). Each pair of facing sprockets, each belonging to a different continuous chain, revolves around an axis (18) that joins them and is dedicated to transmitting the rotating movement of the geared motor (14) to the sprockets (17) and therefore to the conveyor mechanism
Opción 2§: En esta opción (ver figura 5), se trata de un transportador móvil (19), sobre el cual se coloca el equipaje (5) envuelto en la bolsa de material termorretráctil (4). El equipaje queda sin movimiento relativo al transportador (19), sin embargo el desplazamiento horizontal de éste último oriendado hacia dentro o fuera de la cabina (20), da lugar a la introducción del equipaje (4) en el horno (1) o su extracción de él. Este transportador esté compuesto por una estructura hueca de configuración prismático-rectangular cuyos vértices horizontales superiores (21) están conformados a modo de sendas cremalleras con sus caras dentadas orientadas hacia abajo. Dichas cremalleras están engranadas con sendos piñones o ruedas dentadas (22). Option 2§: In this option (see figure 5), it is a mobile conveyor (19), on which the luggage (5) wrapped in the bag of heat shrinkable material (4) is placed. The luggage remains without movement relative to the conveyor (19), however the horizontal displacement of the latter arranged in or out of the cabin (20), results in the introduction of the luggage (4) in the oven (1) or its extraction from him. This conveyor is composed of a hollow structure with a prismatic-rectangular configuration whose upper horizontal vertices (21) are shaped like zippers with their serrated faces facing down. Said zippers are geared with two sprockets or sprockets (22).
Estos piñones (22) están unidos entre si mediante un eje central (23) de tal manera que el movimiento giratorio de éste, obliga a los piñones (22) a efectuar simultáneamente una rotación en la misma dirección que el eje común (23). La rotación de éste último se obtiene mediante el movimiento giratorio que le transmite un motorredυctor eléctrico (no demostrado en la figura 5). Este transportador presenta en su cara superior, es decir lugar donde se coloca el equipaje, una estructura a modo de
emparrillada construida mediante una serie de varillas o tubos metálicos (24) o cualquier material resistente al calor, dispuestos paralelamente y en posición horizontal con los extremos de cada uno fijados solidariamente sobre las cremalleras (21). These pinions (22) are connected to each other by means of a central axis (23) in such a way that the rotational movement of the latter forces the pinions (22) to simultaneously perform a rotation in the same direction as the common axis (23). The rotation of the latter is obtained by the rotating movement transmitted by an electric motor gearbox (not shown in Figure 5). This conveyor presents on its upper face, that is, where the luggage is placed, a structure by way of grid constructed using a series of metal rods or tubes (24) or any heat-resistant material, arranged in parallel and in a horizontal position with the ends of each fixed jointly on the zippers (21).
Todas las opciones de transportadores aquí descritas cuentan con sus respectivos detectores de proximidad (25) capaces de detectar la colocación o no del equipaje sobre el transportador. Dichos detectores están eléctricamente conectados con el cuadro electrónico de mando y control (10). una vez colocado el equipaje sobre el transportador, el detector de proximidad (25) envía la señal de detección al cuadro de mando y control (10), y éste a su vez acciona al motor eléctrico, resultando así en el desplazamiento del equipaje (4) hacia dentro del horno. All the conveyor options described herein have their respective proximity detectors (25) capable of detecting the placement or not of the luggage on the conveyor. Said detectors are electrically connected to the electronic control and control panel (10). once the luggage is placed on the conveyor, the proximity detector (25) sends the detection signal to the control and control panel (10), and this in turn drives the electric motor, resulting in the movement of luggage (4 ) into the oven.
Cabe señalar que en el caso de la segunda opción del transportador, éste permanece, en condiciones de descanso (stand by), en el interior del horno, siendo necesario extraerlo mediante la pulsación de un botón ubicado en el cuadro de mando y control (10). It should be noted that in the case of the second option of the conveyor, it remains, in rest conditions (stand by), inside the oven, being necessary to remove it by pressing a button located on the control and control panel (10 ).
