MÁQUINA PARA LA CONFORMACIÓN DE CÁPSULAS MONODOSIS DE FILM MACHINE FOR FORMING SINGLE-DOSE FILM CAPSULES

HIDROSOLUBLE CON SISTEMA DE CORTE POR LÁSERWATER-SOLUBLE WITH LASER CUTTING SYSTEM

Objeto de la invenciónObject of the invention

El objeto de la presente memoria es una máquina para la conformación de cápsulas monodosis de film hidrosoluble con sistema de corte por láser, en especial de las dedicadas a la creación de cápsulas monodosis de detergente líquido a partir de un film hidrosoluble, y cuya principal característica distintiva radica en el hecho de incorporar un corte por láser que sustituye a los actuales sistemas de corte por cuchillas, que mejora el comportamiento y estabilidad del film (y de la cápsula ya cortada), lo que redunda en un mejor impacto en la disolución de la misma durante el ciclo de lavado si se compara frente a otras soluciones.The object of this report is a machine for the formation of single-dose capsules of water-soluble film with a laser cutting system, especially those dedicated to the creation of single-dose capsules of liquid detergent from a water-soluble film, and whose main characteristic distinctive lies in the fact of incorporating a laser cutting that replaces the current cutting systems by blades, which improves the behavior and stability of the film (and of the capsule already cut), which results in a better impact on the dissolution of the same during the wash cycle when compared to other solutions.

Antecedentes de la invenciónBackground of the invention

En la actualidad es de sobra conocida la existencia de cápsulas de detergente líquido configuradas como pequeñas bolsitas de detergente concentrado, diseñados para introducirse directamente en la lavadora antes de introducir la ropa, y así aprovechar al máximo el poder de limpieza.At present, the existence of liquid detergent capsules configured as small bags of concentrated detergent, designed to be introduced directly into the washing machine before putting the clothes, is well known, thus making the most of the cleaning power.

Cada una de estas cápsulas contiene la dosis correcta y necesaria de producto para una carga de ropa, siendo un formato muy limpio y cómodo de utilizar, que no debe dejar ninguna clase de rastro, porque el envoltorio se disuelve en el agua de la lavadora, y así se aprovecha el 100% del producto sin malgastar nada durante el proceso de lavado.Each of these capsules contains the correct and necessary dose of product for a load of laundry, being a very clean and comfortable format to use, which should not leave any kind of trace, because the packaging dissolves in the washing machine water. and thus 100% of the product is used without wasting anything during the washing process.

Desde su aparición en el mercado, los detergentes en cápsulas monodosis hidrosolubles, se ha presentado como un producto novedoso y cada vez con mayor presencia en los lineales de los supermercados. Pero a pesar de sus ventajas, este producto no está exento de problemas. El más importante, y que más preocupa a los consumidores, es que para que el lavado sea correcto, la cápsula debe disolverse completamente, sin dejar restos de film hidrosoluble.Since their appearance on the market, detergents in water-soluble single-dose capsules have been presented as a new product with an increasing presence on supermarket shelves. But despite its advantages, this product is not without its problems. The most important, and that most worries consumers, is that for the washing to be correct, the capsule must dissolve completely, without leaving traces of water-soluble film.

El proceso de disolución del film depende de múltiples factores, entre los que podemos mencionar algunos como puedan ser el diseño de la citada cápsula (ya que un diseño más circular permite que la cápsula gire con facilidad dentro del tambor de la lavadora, durante el ciclo de lavado y, por tanto, facilite una disolución completa); el espesor y grado de deformación de film utilizado (ya que cuanto mayor sea el espesor del film, la cápsula requerirá más tiempo para una disolución completa del mismo), así como otros factores que dependen del uso por parte del usuario, tales como el ciclo de lavado (por ejemplo, en los ciclos cortos de lavado, existe un mayor riesgo de que no dé tiempo a una completa disolución del film), condiciones del lavado (temperatura del agua y grado de humedad) o el tipo de lavadora.The dissolution process of the film depends on multiple factors, among which we can mention some such as the design of the aforementioned capsule (since a more circular allows the capsule to rotate easily inside the drum of the washing machine, during the wash cycle and, therefore, facilitates a complete dissolution); the thickness and degree of deformation of the film used (since the greater the thickness of the film, the capsule will require more time for a complete dissolution of the same), as well as other factors that depend on the use by the user, such as the cycle washing conditions (for example, in short washing cycles, there is a greater risk that the film does not have time to completely dissolve), washing conditions (water temperature and degree of humidity) or the type of washing machine.

Por todo lo anteriormente expuesto, se puede extraer como conclusión importante, que cuanto menos film se emplee, por lógica menor posibilidades hay de que queden restos en el tambor o la ropa tras el lavado.For all the above, it can be drawn as an important conclusion that the less film is used, logically the less likely there is to remain in the drum or clothes after washing.

Para la materialización de dichas monodosis son conocidos diversos métodos o máquinas encargadas de fabricar monodosis de film hidrosoluble de detergente que utilizan un sistema de corte basado en una combinación de cuchillas longitudinales y transversales, que sólo permiten hacer un corte rectangular/cuadrado. Este sistema de corte te limita a tener un diseño de cápsula rectangular/cuadrado, para reducir el exceso de film o, de lo contrario, un diseño circular tendrá un exceso de film, que podría no disolverse por completo y dejar restos.For the materialization of said single doses, various methods or machines are known in charge of manufacturing single doses of water-soluble detergent film that use a cutting system based on a combination of longitudinal and transverse blades, which only allow making a rectangular / square cut. This cutting system limits you to having a rectangular / square capsule design, to reduce excess film or, otherwise, a circular design will have excess film, which may not dissolve completely and leave residue.

Para paliar dicha problemática, la invención aquí propuesta emplea un sistema de corte por láser para la cápsula; es conocido, que en dicha industria se emplean soluciones de tecnología láser desde hace años en la industria de los plásticos, sobre todo como marcaje o tecnología de perforación, tal y como sucede en la solicitud WO2014182602A1 que describe un proceso de uso de láseres que tienen una potencia desde aproximadamente 0,5 vatios a aproximadamente 20 vatios para perforar orificios que tienen anchos máximos de aproximadamente 300 ^m en películas, más específicamente, películas utilizadas para preparar bolsas que contienen composiciones detergentes. El solicitante desconoce de la existencia de soluciones que empleen el corte por láser destinado al corte de film hidrosoluble, con las mejoras en cuanto a la estabilidad del film y de la cápsula así como su comportamiento dentro de la lavadora.To alleviate this problem, the invention proposed here uses a laser cutting system for the capsule; It is known that in this industry laser technology solutions have been used for years in the plastics industry, especially as marking or drilling technology, as in the application WO2014182602A1 that describes a process of using lasers that have a power from about 0.5 watts to about 20 watts for punching holes having maximum widths of about 300 µm in films, more specifically, films used to prepare bags containing detergent compositions. The applicant is unaware of the existence of solutions that use laser cutting for cutting water-soluble film, with improvements in the stability of the film and the capsule as well as their behavior within the washing machine.

Descripción de la invenciónDescription of the invention

El problema técnico que resuelve la presente invención es conseguir una máquina para la conformación de cápsulas hidrosolubles de detergente líquido que reduzca la cantidad de exceso de film sobrante (o lo minimice al máximo) y a su vez sea capaz de generar una cápsula de detergente tricámara funcional con una cantidad de film suficiente para ser capaz de formar una cápsula estable reduciendo el film necesario al mínimo imprescindible para un óptimo rendimiento. Para ello, la máquina para la conformación de cápsulas monodosis de film hidrosoluble con sistema de corte por láser, objeto del presente modelo de utilidad, comprende esencialmente una estructura que aloja unos medios de conformación de la cápsula y dicha estructura se encuentra solidariamente unida con otro chasis adyacente a él que aloja un sistema de corte compuesto esencialmente por al menos cuatro sistemas láser de CO2 refrigerados por líquido asociados con al menos cuatro cabezales de escaneo láser de CO2; encargado de realizar el corte de las cápsulas directamente sobre el tambor.The technical problem solved by the present invention is to achieve a machine for the shaping of water-soluble liquid detergent capsules that reduces the amount of excess excess film (or minimizes it to the maximum) and in turn is capable of generating a functional three-chamber detergent capsule with a sufficient amount of film to be able to form a stable capsule reducing the necessary film to the minimum necessary for optimum performance. To this end, the machine for shaping single-dose capsules of water-soluble film with a laser cutting system, object of this utility model, essentially comprises a structure that houses some means of shaping the capsule and said structure is integrally joined with another chassis adjacent to it housing a cutting system essentially composed of at least four liquid-cooled CO2 laser systems associated with at least four CO2 laser scanning heads; in charge of cutting the capsules directly on the drum.

Gracias a su diseño, la máquina conformará cápsulas tricámara donde el film actuará como barrera de contención del detergente, garantizando un buen sellado y el correcto mantenimiento de las propiedades de la cápsula, por lo que el film no debe sufrir ningún daño durante el corte, ni comprometer la estabilidad ni el sellado de la cápsula, hecho que se solventa sobradamente gracias a su sistema de corte por láser.Thanks to its design, the machine will form three-chamber capsules where the film will act as a detergent containment barrier, guaranteeing a good seal and the correct maintenance of the properties of the capsule, so the film must not suffer any damage during cutting. nor compromise the stability or the sealing of the capsule, a fact that is more than solved thanks to its laser cutting system.

La máquina aquí descrita para solucionar la problemática anteriormente explicada dispone de un sistema de corte por láser con una distancia óptima de corte que facilita la consecución de dicho objetivo, frente a los sistemas de corte por cuchillas empleados en la actualidad.The machine described here to solve the previously explained problem has a laser cutting system with an optimal cutting distance that facilitates the achievement of said objective, compared to the knife cutting systems currently used.

De igual forma, la máquina dispone de un sistema de extracción de humos derivados de la operación de corte de la cápsula, especialmente diseñados para la extracción de los humos nocivos que se producen en dicha operación, mediante un sistema de extracción forzada con medios de filtrados adecuados a tal fin.Similarly, the machine has a system for the extraction of fumes derived from the cutting operation of the capsule, specially designed for the extraction of the harmful fumes that are produced in said operation, by means of a forced extraction system with filter media. suitable for this purpose.

Otra ventaja de la máquina aquí descrita radica en que está diseñada para transmitir las señales de corte desde los medios lógicos de control de la máquina hasta la aplicación de corte por láser, de esta forma se consigue que el corte se produzca de forma dinámica, en el lugar correcto, con la mayor precisión y sin desviaciones. Hay que tener en cuenta que se trata de una máquina rotativa, compuesta por un "tambor” de moldes, que va girando continuamente, y el corte láser tiene que acompañar el movimiento del tambor, por ello dicho sistema cuenta con unos medios de transmisión de la posición, lo que permite determinar el momento exacto del corte. Another advantage of the machine described here is that it is designed to transmit the cutting signals from the logic control means of the machine to the application of laser cutting, in this way it is achieved that the cut occurs dynamically, in the right place, with the greatest precision and without deviations. It must be taken into account that it is a rotating machine, composed of a "drum" of molds, which rotates continuously, and the laser cut has to accompany the movement of the drum, for this reason said system has transmission means of the position, which allows to determine the exact moment of the cut.

Finalmente, la máquina contará con unos medios de sustentación de la cápsula conformada, para que una vez que la cápsula haya sido cortada, pueda quedarse girando libremente en el tambor de moldes, para posteriormente separarse del mismo y caer por la banda diseñada a tal efecto.Finally, the machine will have support means for the shaped capsule, so that once the capsule has been cut, it can remain spinning freely in the mold drum, to later separate from it and fall through the band designed for this purpose. .

El funcionamiento de la máquina radica en diversas etapas donde, esencialmente, el film hidrosoluble se desenrolla desde la zona de alimentación de film hacia el tambor, a través de un sistema de rodillos que lo tensan y alinean adecuadamente (evitando cualquier tipo de arrugas); previo paso por un sistema de precalentamiento que permite su adaptabilidad al molde de forma sencilla.The operation of the machine lies in various stages where, essentially, the water-soluble film is unwound from the film feed area towards the drum, through a system of rollers that tighten and align it properly (avoiding any type of wrinkles); after passing through a preheating system that allows its adaptability to the mold in a simple way.

Una vez que el film llega al tambor, éste adopta la forma final deseada, es decir la de los moldes contenidos en el tambor, gracias al sistema de aspiración en vacío. A continuación, el producto “semielaborado” que se encuentra almacenado en unos depósitos instalados en la zona de conformación de la máquina, llega hasta unas boquillas de dosificación del producto a través de una pluralidad de bombas de alta precisión que funcionan por pulsos. De esta forma, el producto se dosifica en la cavidad mientras que paralelamente otra capa de film se desenrolla desde otra estación de alimentación del film, humedeciéndose levemente mediante un rodillo y se sella la cápsula con el producto alojado en su interior.Once the film reaches the drum, it adopts the desired final shape, that is, that of the molds contained in the drum, thanks to the vacuum suction system. Next, the "semi-finished" product that is stored in tanks installed in the forming area of the machine, reaches some product dosing nozzles through a plurality of high-precision pumps that operate by pulses. In this way, the product is dosed into the cavity while in parallel another layer of film is unrolled from another film feeding station, slightly moistening by means of a roller and the capsule is sealed with the product housed inside.

Posteriormente, se produce el corte de estas mediante un sistema de láseres de CO2 donde gracias a un dispositivo codificador o “encoder” se conseguirá obtener la posición exacta de la cápsula dentro del tambor y una vez que se reciba la señal del momento exacto para realizar el corte (incluyendo un retardo), se activarán dichos láseres realizando tanto el marcado como el corte exacto.Subsequently, these are cut by means of a CO2 laser system where, thanks to an encoding device or "encoder", it will be possible to obtain the exact position of the capsule inside the drum and once the signal of the exact moment is received to perform cutting (including a delay), these lasers will be activated performing both marking and exact cutting.

De esta forma, la máquina aquí preconizada no sólo conseguirá reducir la cantidad de desecho de film en el corte, sino que a su vez, podrá aplicar distintas formas al corte, no solo circular, pudiendo ampliar los diseños de este tipo de cápsulas adecuándolas a otras con mejores rendimientos en cuanto a disolubilidad.In this way, the machine recommended here will not only be able to reduce the amount of film waste in the cut, but at the same time, it will be able to apply different shapes to the cut, not only circular, being able to expand the designs of this type of capsules adapting them to others with better performance in terms of dissolubility.

Finalmente, las cápsulas serán liberadas y transportadas de manera ordenada.Finally, the capsules will be released and transported in an orderly manner.
