En la aplicación de colas termofusibles se utilizan fusores para transformar la cola de un estado sólido, en el que convencionalmente se suministra, a un estado fluido necesario para la aplicación.In the application of hot melts, they use fusers to transform the tail of a solid state, into the which is conventionally supplied, at a necessary fluid state For the application.
Convencionalmente los fusores destinados para transformar las colas termofusibles al estado fluido de aplicación, son unos grandes depósitos que se sitúan a cierta distancia del cabezal mediante el que se realiza la aplicación de la cola.Conventionally the fusers intended for transform hot melts to the fluid state of application, they are large deposits that are located at a certain distance from the head by means of which the application of the tail is realized.
Desde el fusor hasta el cabezal de aplicación, la cola fundida se transporta a través de mangueras calefactadas y recubiertas de aislante, para que la cola fundida llegue al cabezal de aplicación en las condiciones de fluidez necesarias.From the fuser to the application head, the molten tail is transported through heated hoses and insulated, so that the molten tail reaches the head of application in the conditions of fluidity necessary.
Estas disposiciones convencionales, necesitan un gran espacio de instalación, debido a la independencia y ubicación por separado de los elementos de fusión y de aplicación de las colas, y además, para que la cola fundida llegue adecuadamente al cabezal de aplicación, se necesitan mangueras de conducción calefactadas, lo cual incrementa el gasto energético.These conventional provisions, need a large installation space, due to independence and location separately from the elements of fusion and application of tails, and also, so that the molten tail properly reaches the application head, conduction hoses are needed heated, which increases energy expenditure.
De acuerdo con la invención se propone un cabezal compacto, en el cual se incluyen incorporados conjuntamente el fusor de la cola y el elemento aplicador, de manera que el paso de la cola fundida entre ambos elementos es directo, sin necesidad de conducción por mangueras calefactadas.According to the invention, a compact head, which are incorporated together the fuser of the glue and the applicator element, so that the step of the molten tail between both elements is direct, no need of driving by heated hoses.
Este cabezal objeto de la invención, incluye un depósito calefactado para fundir la cola y una cabeza de aplicación, incorporando una bomba de impulsión para pasar la cola fundida del depósito de fusión hasta la cabeza de aplicación.This head object of the invention includes a heated tank to melt the glue and an application head, incorporating a drive pump to pass the molten tail of the Fusion tank to the application head.
El depósito fusor puede ser de forma variable, abierto o cerrado de manera hermética, en el cual se introduce la cola termofusible en estado sólido, de modo que en el interior, debido al calor que proporcionan unas resistencias eléctricas dispuestas alrededor de dicho deposito, la cola se funde adquiriendo un estado fluido, para ser impulsada hacia la cabeza de aplicación.The fuser tank can be variable, hermetically opened or closed, in which the hot melt glue in solid state, so that inside, due to the heat provided by electrical resistors arranged around said deposit, the tail melts by acquiring a fluid state, to be propelled towards the head of application.
El depósito fusor se prevé rodeado de una capa aislante, para evitar las pérdidas de calor hacia el exterior, con el fin de conseguir el máximo aprovechamiento del consumo energético que se utiliza para la fusión de las colas.The fuser deposit is envisaged surrounded by a layer insulator, to avoid heat losses to the outside, with in order to achieve maximum use of energy consumption which is used for the fusion of the tails.
Por todo ello, dicho cabezal compacto objeto de la invención ofrece unas características que resultan ciertamente ventajosas, adquiriendo vida propia y carácter preferente respecto de los cabezales convencionales con elementos separados que se emplean para la aplicación de las colas termofusibles.Therefore, said compact head object of the invention offers characteristics that are certainly advantageous, acquiring a life of its own and preferential character of conventional heads with separate elements that are used for the application of hot melts.
La figura 1 es una perspectiva de un ejemplo constructivo del cabezal compacto de aplicación de colas termofusibles, según la invención.Figure 1 is a perspective of an example construction of the compact tail application head hot melts, according to the invention.
La figura 2 es una sección vertical de dicho cabezal compacto objeto de la invención.Figure 2 is a vertical section of said compact head object of the invention.
La figura 3 es una sección en planta del mismo cabezal compacto anterior.Figure 3 is a plan section of the same front compact head.
La figura 4 es una perspectiva de otro ejemplo constructivo del cabezal compacto preconizado.Figure 4 is a perspective of another example construction of the recommended compact head.
El objeto de la invención se refiere a un cabezal compacto para aplicación de colas termofusibles, en el cual se incluyen tanto el elemento destinado para la fusión de la cola, como el elemento de aplicación de la cola fundida.The object of the invention relates to a compact head for application of hot melts, in which both the element destined for the fusion of the tail is included, as the application element of the molten tail.
El cabezal compacto preconizado consta de un depósito fusor (1), el cual como muestra la figura 1 puede tener forma cilíndrica, pudiendo también tener otras formas, como por ejemplo una forma prismática, como representa la figura 4, sin que ello altere el concepto del cabezal aplicador de las colas termofusibles ni su función. Para determinadas colas que reticulan con la humedad del aire, como por ejemplo las colas poliuretánicas, dicho depósito fusor (1) debe establecerse herméticamente cerrado, mientras que para otros tipos de colas que no presentan esta particularidad, no se necesita un cierre hermético.The recommended compact head consists of a fuser tank (1), which as shown in figure 1 can have cylindrical shape, may also have other shapes, such as by example a prismatic form, as shown in figure 4, without this alters the concept of the tail applicator head Hot melts or their function. For certain queues that crosslink with air humidity, such as polyurethane glues, said fuser tank (1) must be tightly sealed, while for other types of queues that do not present this particularity, a tight seal is not needed.
Dicho depósito fusor (1) va acoplado en conexión directa respecto de una cabeza (2) de aplicación de la cola, que puede ser de tipo de labio o de cualquier otra forma convencional de las boquillas existentes de aplicación de colas, disponiendo el conjunto de una bomba (3), destinada para impulsar la cola fundida desde el depósito fusor (1) hasta la cabeza (2) de aplicación.Said fuser tank (1) is coupled in connection direct with respect to a head (2) of application of the tail, which it can be of lip type or any other conventional form of existing queue application nozzles, providing the pump assembly (3), designed to drive the molten tail from the fuser tank (1) to the application head (2).
El deposito fusor (1) se dispone rodeado de resistencias eléctricas (no representadas), en una cámara periférica (4) que se establece llena de material aislante, y en la base dicho depósito (1) determina una serie de salidas (5) de paso hasta una cámara (6), la cual a su vez se halla comunicada a través de un conducto (7) con la cabeza (2) de aplicación de las colas, yendo incorporadas en los espacios entre las salidas (5) y alrededor de la cámara (6), resistencias eléctricas (8).The fuser tank (1) is surrounded by electrical resistors (not shown), in a peripheral chamber (4) which is established full of insulating material, and at the base said tank (1) determines a series of outputs (5) of passage up to a chamber (6), which in turn is communicated through a duct (7) with the head (2) of application of the tails, going incorporated into the spaces between the exits (5) and around the chamber (6), electrical resistors (8).
Con ello así, la cola destinada para la aplicación se introduce en estado sólido en el depósito (1), cayendo por gravedad al fondo provisto con las salidas (5), de forma que merced al calor que proporcionan las resistencias que rodean al depósito (1) se produce una fusión inicial de la cola, la cual en las salidas (5) de la base termina de fundir, merced al calor de las resistencias (7) que se hallan en los espacios entre las mencionadas salidas (5), fluyendo la cola fundida hasta la cámara (6), en donde se mantiene el estado de fusión, y desde dicha cámara (6) la cola fundida es impulsada por la bomba (3) hasta la cabeza (2) de aplicación, en el transcurso hasta la cual se hallan incluidas también resistencias eléctricas (8) para mantener la cola en el adecuado estado de fluidez para la aplicación.With this, the queue destined for application is introduced in solid state in the tank (1), falling by gravity to the bottom provided with the outputs (5), so that thanks to the heat provided by the resistances surrounding the deposit (1) an initial fusion of the tail occurs, which in the outlets (5) of the base finishes melting, thanks to the heat of the resistors (7) found in the spaces between the mentioned exits (5), the molten tail flowing to the chamber (6), where the fusion state is maintained, and from said chamber (6) the tail molten is driven by the pump (3) to the head (2) of application, in the course until which they are included also electrical resistors (8) to keep the tail in the adequate state of fluidity for the application.
En estas condiciones, la cola sólida que se introduce en el depósito (1) se va fundiendo progresivamente en dicho depósito (1), de manera que llega a las salidas inferiores (5) en un estado semifundido, adquiriendo en dichas salidas (5) una fluidez que la permite pasar hasta la cámara (6), de modo que en ese transcurso y en la cámara (6) se completa y mantiene la fusión, impulsándose la cola fundida directamente desde la zona de fusión hacia la cabeza (2) de aplicación, de modo que no existen transcursos de circulación largos en los que la cola pueda enfriarse y perder fluidez, en tanto que el conjunto del cabezal resulta de una dimensión que le permite ser utilizado en espacios reducidos.Under these conditions, the solid tail that enter the tank (1) gradually melts into said tank (1), so that it reaches the lower exits (5) in a semi-molten state, acquiring in said outputs (5) a fluidity that allows it to pass to the chamber (6), so that in that course and in the chamber (6) the fusion is completed and maintained, the molten tail being driven directly from the fusion zone towards the application head (2), so that they do not exist long circulation paths in which the tail can cool and lose fluidity, while the head assembly results from a dimension that allows it to be used in spaces reduced
