DESCRIPCIONDESCRIPTION

Precintadora automatica de cinta adhesiva termica.Automatic thermal tape sealer.

La presente invention se refiere a un dispensador de cinta de precinto para acoplarlo a una ilnea automatica de precintado, que llamaremos precintadora termica, particularmente para ser utilizada de modo automatico, que a diferencia de las precintadoras anteriores de cinta autoadhesiva, opera mediante la aplicacion de calor en el momento del desenrollado de la cinta. La cinta de precinto es preferentemente de papel, de modo que dicha cinta de papel solo adquiere condition de adhesiva una vez se le ha aportado el calor necesario para su aplicacion.The present invention relates to a seal tape dispenser for coupling it to an automatic sealing line, which we will call thermal sealing, particularly to be used automatically, which unlike previous self-adhesive tape sealers, operates by applying heat at the time of unwinding the tape. The sealing tape is preferably made of paper, so that said paper tape only acquires an adhesive condition once the heat necessary for its application has been provided.

En el momento actual esta muy extendida la utilization de estas llneas de precintado, utilizadas en todo tipo de industria. Estas maquinas utilizan cintas autoadhesivas normalmente de material plastico, tal como polipropileno, poliester o PVC, y normalmente estan realizadas en color marron, blanco, transparente, aunque tambien pueden ser encontradas en papel autoadhesivo; en estas cintas de papel debe evitarse la adherencia ente las capas del rollo, por ejemplo mediante la adicion de capas de recubrimiento, en general de un material plastico o mediante el uso de parafinas antiadherentes en la capa no adhesiva del papel.At present, the use of these sealing lines, used in all types of industry, is widespread. These machines use self-adhesive tapes normally of plastic material, such as polypropylene, polyester or PVC, and are usually made in brown, white, transparent, although they can also be found on self-adhesive paper; In these paper tapes, adhesion between the layers of the roll should be avoided, for example by adding coating layers, in general of a plastic material or by using non-stick paraffins in the non-adhesive layer of the paper.

La comodidad y practicidad del sistema es suficiente. Sin embargo estan utilizando como un material plastico que presenta muchas caracterlsticas negativas. El plastico es un producto contaminante. El reciclado de carton o papel que esta unido a material plastico requiere de un tratamiento de elimination de dicho material; ademas, la elimination, por ejemplo por incineration de los residuos plasticos, si bien puede utilizarse para la obtencion de energla, genera gases contaminantes, que en algunos casos son toxicos. Esta circunstancia desaconseja el uso del plastico con caracter general, y particularmente el utilizado en precinto de embalajes.The comfort and practicality of the system is sufficient. However they are using as a plastic material that has many negative characteristics. Plastic is a polluting product. The recycling of cardboard or paper that is attached to plastic material requires a treatment of elimination of said material; In addition, elimination, for example by incineration of plastic waste, although it can be used to obtain energy, generates polluting gases, which in some cases are toxic. This circumstance discourages the use of plastic in general, and particularly that used in packaging seals.

Existen cintas de papel adhesivas, estas cintas tienen el inconveniente que para evitar la adhesion a la capa de papel de la vuelta anterior, este debe estar tratado con un medio antiadherente en una de sus caras, resultando un proceso caro.There are adhesive paper tapes, these tapes have the disadvantage that in order to avoid adhering to the paper layer of the previous turn, this must be treated with a non-stick means on one of its faces, resulting in an expensive process.

Se han utilizado como precinto cintas de papel para ser adheridas a dos partes, por ejemplo las aletas de cierre de una caja de carton. Esta utilizacion se ha realizado con papel engomado, que al modo de los sobres antiguos, contienen un adhesivo que se activa mediante la humedad, que debe aportarse en el momento de la operation de precintado. Este tipo de precintos presentan problemas por ser sus precintadoras menos versatiles que las de cinta plastica que finalmente las han desplazado, toda vez que necesitan el correspondiente aporte de agua y no son aconsejables para algunos sustratos o bien temperaturas humedas.Paper tapes have been used as a seal to be adhered to two parts, for example the closure flaps of a cardboard box. This use has been made with gummed paper, which, like old envelopes, contains an adhesive that is activated by moisture, which must be provided at the time of the sealing operation. These types of seals present problems because their seals are less versatile than those of plastic tape that have finally displaced them, since they need the corresponding water supply and are not advisable for some substrates or humid temperatures.

Estado de la tecnica anteriorState of the prior art

ES 1078394 U tiene por objeto un papel continuo con adhesivo activado por calor que constituye precisamente la base tecnologica de la presente invencion. Consiste en una cinta de papel continuo con adhesivo que se activa mediante aportacion termica, de modo que solamente esta en condiciones de adherirse cuando el calor se ha aplicado. A temperatura ambiente no es adhesiva la capa que en caliente si lo es, constituyendo simplemente un papel cubierto por una parte por una capa que no es adhesiva al tacto ni al contacto. Este papel puede aplicarse mediante la aplicacion de calor directo, por ejemplo mediante una plancha o similar en la position de precintado. Sin embargo, esta option ni resulta posible aplicarla en la industria, ni proporciona condiciones de seguridad en la aplicacion, que debe atender criterios de fiabilidad en la ejecucion del cierre o precintado de cajas o productos.ES 1078394 U is intended for a continuous paper with heat activated adhesive that constitutes precisely the technological basis of the present invention. It consists of a continuous paper tape with adhesive that is activated by thermal input, so that it is only able to adhere when the heat has been applied. At room temperature, the hot layer is not adhesive if it is, simply constituting a paper covered on one side by a layer that is not adhesive to touch or contact. This paper can be applied by direct heat application, for example by means of an iron or the like in the sealing position. However, this option is neither possible to apply in the industry, nor does it provide security conditions in the application, which must meet reliability criteria in the execution of the closure or sealing of boxes or products.

La tecnica de aplicar precinto desde un rollo de precinto de material plastico consiste en colocarla en el portarrollos y hacerla pasar por una series de rodillos hasta un rodillo aprisionador o de aplicacion, de modo que su cara adhesiva queda al exterior, este rodillo fija y aprisiona el precinto a lo largo de su recorrido hasta que termina la superficie horizontal de la caja, y cuando hace el corte por incision de la cuchilla o algun diente de sierra del cortador en la cinta, y el posterior desgarrado del resto de la seccion mediante el tiraje, un segundo rodillo fija el resto del precinto en la porcion vertical de la caja.The technique of applying a seal from a roll of plastic material seal is to place it in the roll holder and pass it through a series of rollers to a pinch or application roller, so that its adhesive face is outside, this roller fixed and imprisoned the seal along its path until the horizontal surface of the box ends, and when it makes the cut by incision of the blade or some sawtooth of the cutter on the tape, and the subsequent tearing of the rest of the section by means of the run, a second roller fixes the rest of the seal in the vertical portion of the box.

Sin embargo, el adhesivo que posee el precinto plastico asl como el adhesivo general de precintos de papel existentes se deteriora con el ambiente, humedad, cambios de temperatura, radiacion solar, etc. Por el contrario, las colas termicas no presentan dichos inconvenientes.However, the adhesive that has the plastic seal as well as the general adhesive of existing paper seals deteriorates with the environment, humidity, temperature changes, solar radiation, etc. On the contrary, thermal glues do not have such disadvantages.

Explicacion de la invencionExplanation of the invention

La invencion que se propone consiste en un dispositivo precintador para ser utilizado en una maquina de precintado automatico, que utiliza cinta de papel provista de un adhesivo termico, es decir, que adquiere condiciones de adhesividad a partir de cierta temperatura, siendo el dispositivo de la invencion el que aporta el calor necesario para dotar a la cinta de la temperatura requerida para su aplicacion. Asl, se requiere que el aporte de calor a la cinta tenga lugar de modo que se realice desde el lado de dicha cinta que no esta provisto de la cola termica, y ademas dicho aporte de calor ha de ser suficiente como para activar el adhesivo, aunque se extraiga la cinta de papel a cierta velocidad.The proposed invention consists of a sealing device to be used in an automatic sealing machine, which uses paper tape provided with a thermal adhesive, that is, it acquires adhesive conditions from a certain temperature, the device being the invention that provides the heat necessary to provide the tape with the temperature required for its application. Thus, it is required that the heat input to the tape take place so that it is made from the side of said tape that is not provided with the thermal glue, and in addition said heat input must be sufficient to activate the adhesive, even if the paper tape is removed at a certain speed.

Segun una opcion, se han dispuesto para ello medios que obtienen la aplicacion de calor de forma selectiva, de forma tal que no operan mas que cuando se extrae la cinta de papel con cola termica. Segun otra opcion se mantiene la temperatura de activacion en una parte de la precintadora, proporcionando un aporte permanente de calor a tal efecto.According to one option, means have been arranged for this purpose that obtain heat application selectively, so that they do not operate more than when the paper tape with thermal glue is removed. According to another option, the activation temperature is maintained in a part of the sealer, providing a permanent supply of heat for this purpose.

Segun otra opcion, cuando la precintadora esta en activo (por ejemplo en modo de marcha), se mantiene una temperatura proxima a la de activacion, y se complementa con el aporte de calor necesario cuando la cinta esta en movimiento.According to another option, when the sealing machine is active (for example in running mode), a temperature close to that of activation is maintained, and is complemented by the necessary heat input when the belt is in motion.

Los cortadores de sierra utilizados para las cintas de plastico, obtienen el corte por desgarro cuando una sola de las puas de la sierra ha incidido en el plastico. Serla posible utilizar dichos cortadores o cuchilla y su practica de modo de corte serla exactamente la misma.The saw cutters used for the plastic belts, obtain the tear cut when only one of the saws of the saw has affected the plastic. It would be possible to use such cutters or blade and its practice of cutting mode would be exactly the same.

Asl, la presente invencion consiste en un dispositivo precintador termico, de utilization en maquinas de precintado automatico, que comprende los siguientes elementos:Thus, the present invention consists of a thermal sealing device, for use in automatic sealing machines, comprising the following elements:

• Un soporte o chasis de los distintos elementos;• A support or chassis of the different elements;

• soporte de rollo con un eje portarrollos;• roll holder with a roll holder shaft;

• normalmente una gula de paso del precinto;• normally a seal of the seal;

• posiblemente un dispositivo de avance del precinto;• possibly a seal advancement device;

• un elemento aplicador del precinto;• an application element of the seal;

• un medio calentador del precinto, normalmente en el elemento aplicador o en una pista de calentamiento;• a heating means of the seal, usually in the applicator element or in a heating track;

• un medio de corte del precinto.• a means of cutting the seal.

El soporte o chasis presenta una configuration semejante a los aplicadores de precinto automaticos conocidos. Del mismo modo el conjunto utilizan dicha configuracion esencial.The support or chassis has a configuration similar to the known automatic seal applicators. In the same way the set use this essential configuration.

El eje portarrollos aloja un rollo de precinto. El rollo de precinto esta formado por una cinta de papel, que esta impregnada en uno de sus lados de una cola termica, que toma condiciones de adherencia unicamente por encima de determinada temperatura, es decir, que se activaThe roll holder shaft houses a seal roll. The seal roll is formed by a paper tape, which is impregnated on one of its sides of a thermal glue, which takes adhesion conditions only above a certain temperature, that is, it is activated

unicamente por medio de calor. El rollo de precinto no presenta adhesion alguna entre las capas de cada vuelta de papel antes de ser activado termicamente.only by means of heat. The seal roll has no adhesion between the layers of each paper turn before being thermally activated.

El elemento aplicador del precinto esta formado normalmente por un rodillo de giro libre.The sealing element of the seal is normally formed by a free-spin roller.

El medio calentador del precinto se dispondra normalmente en el elemento aplicador, particularmente un rodillo aplicador, o en un patln o pista de deslizamiento por la que pasa el precinto desde el rollo hasta el elemento aplicador.The heating means of the seal will normally be arranged in the applicator element, particularly an applicator roller, or in a slide or sliding track through which the seal passes from the roll to the applicator element.

Los dispositivos precintadotes automaticos suelen tener un rodillo de acabado, que oprime el precinto sobre la caja tras haber sido aplicado por el rodillo aplicador. Segun la invention, dicho rodillo de acabado puede estar tambien dotado de medios calefactores.Automatic sealing devices usually have a finishing roller, which presses the seal onto the box after it has been applied by the applicator roller. According to the invention, said finishing roller can also be provided with heating means.

El medio calentador esta provisto de una fuente de calor. Esta fuente de calor puede estar formada por una o mas de las siguientes:The heating medium is provided with a heat source. This heat source may be formed by one or more of the following:

• Al menos una resistencia electrica;• At least one electrical resistance;

• Una fuente de radiation infrarroja.• A source of infrared radiation.

• Un conducto de paso de aire o gases calientes• A passage of air or hot gases

El dispositivo de la invencion comprendera las conexiones o conducciones correspondientes. En cada caso, obviamente, se dispondran de las conducciones a circuito de paso de aire caliente, o cables de conexion a la correspondiente resistencia o fuente infrarroja.The device of the invention will comprise the corresponding connections or conduits. In each case, obviously, the conduits to the hot air passage circuit, or connection cables to the corresponding resistance or infrared source will be available.

Normalmente el medio calentador estara dispuesto interiormente en el elemento aplicador y/o en la pista de paso del precinto, desde el correspondiente rodillo tensor.Normally the heating means will be arranged internally in the applicator element and / or in the passageway of the seal, from the corresponding tension roller.

Comprende tambien un medio de corte del precinto. Este medio de corte del precinto puede ser una gula de corte en forma de dientes de sierra o bien una cuchilla fija o movil.It also includes a means of cutting the seal. This means of cutting the seal can be a glutton in the form of saw teeth or a fixed or mobile blade.

Al iniciarse la operation de precintado, en tanto que se haya comprobado que existe precinto en el aparato, la parte libre del dispositivo precintador se calienta, y apoya sobre la caja, por lo que el adhesivo que esta en esa zona, que se ha calentado para su aplicacion, queda adherido a la parte frontal de la caja; a continuation, la caja continua su paso por la zona de precintado, arrastrando el precinto, que se desliza a lo largo de la superficie caliente, bien la superficie cillndrica de un rodillo, bien a lo largo de la superficie del cuerpo adaptado para tal fin o de ambas. Tambien puede desplazarse el dispositivo precintador y estar la caja inmovil, pero produciendose en cualquier caso el efecto de velocidad relativa entre caja y precintador. La pequena masa del papel y recubrimiento de cola termica, y la transmision directa de calor por el contacto del papel con una superficie caliente o su paso por una camara caliente o radiante, hacen que la cola termica adquiera las condiciones de temperatura adecuadas para ejercer su funcion. Al apoyar el precinto sobre la caja de carton (u otro paquete que haya que precintar) se produce una adherencia entre ambos, e inmediatamente un rapido enfriado por efecto de la gran superficie expuesta, la transmision de calor desde el precinto al embalaje y al ambiente en su superficie externa. El dispositivo de aplicacion del precinto se desplaza a lo largo de la superficie a precintar, extrayendo del rollo de precinto la longitud necesaria conforme se realiza la aplicacion. Todo el precinto se hace pasar por la superficie caliente o la zona adaptada, de modo que toma condiciones de adherencia al apoyarlo sobre la superficie a precintar. Terminada la operacion se produce el corte de la cinta de precinto de forma tradicional, y el rodillo aplicador u otro rodillo realiza la action de remate del precintado en la portion vertical.When the sealing operation is started, as long as it has been verified that there is a seal in the apparatus, the free part of the sealing device is heated, and rests on the box, so that the adhesive that is in that area, which has been heated for its application, it is attached to the front of the box; then, the box continues its passage through the sealing zone, dragging the seal, which slides along the hot surface, either the cylindrical surface of a roller, or along the surface of the body adapted for this purpose or both. The sealing device can also be moved and the box immovable, but in any case the effect of relative speed between the box and the belt is produced. The small mass of the paper and thermal glue coating, and the direct transmission of heat by the contact of the paper with a hot surface or its passage through a hot or radiant chamber, make the thermal glue acquire the appropriate temperature conditions to exert its function. By supporting the seal on the cardboard box (or other package to be sealed), an adhesion between the two occurs, and immediately a rapid cooling due to the large exposed surface, the transmission of heat from the seal to the packaging and the environment on its outer surface. The seal application device moves along the surface to be sealed, removing the necessary length from the seal roll as the application is made. The entire seal is passed through the hot surface or the adapted area, so that it takes on adhesion conditions when resting on the surface to be sealed. Once the operation is finished, the sealing of the sealing tape is cut in a traditional way, and the applicator roller or other roller performs the sealing action of the sealing in the vertical portion.

Conforme a una option, la temperatura de uso se mantiene constante, disponiendo la precintadora los sensores (termostatos) y reguladores necesarios para ajustar el suministroAccording to one option, the operating temperature is kept constant, with the sealer having the necessary sensors (thermostats) and regulators to adjust the supply

electrico, etc. a las condiciones requeridas; segun otra opcion la temperatura viene regulada por la fuente externa, por ejemplo en el caso de que se utilice aire caliente, u otro fluido.electric, etc. to the required conditions; according to another option the temperature is regulated by the external source, for example in the case that hot air, or other fluid is used.

Segun una realization alternativa, la temperatura se mantiene en un umbral mlnimo, y solamente cuando se produce una activation voluntaria o movimiento del rollo de papel, del rodillo termico o activacion de avance del producto al que se va a precintar se alcanza la temperatura optima, teniendo asl una minimization de consumo, manteniendo en todo momento las condiciones de operation.According to an alternative embodiment, the temperature is kept at a minimum threshold, and only when there is a voluntary activation or movement of the paper roll, of the thermal roller or activation of advance of the product to be sealed is the optimum temperature reached, having a minimization of consumption, maintaining the operation conditions at all times.

Se considera conveniente que la precintadora tenga un separador termico que impida que la temperatura sea transmitida a zonas de papel no deseadas, asl como un sistema sencillo de separation en modo espera para que la cinta adhesiva de papel no este en contacto sobre la fuente de calor.It is considered appropriate that the sealing machine has a thermal separator that prevents the temperature from being transmitted to unwanted paper areas, as well as a simple standby separation system so that the paper adhesive tape is not in contact with the heat source .

Puede tambien comprender la precintadora un rodillo tensor, que obligue al precinto a contactar con una mayor superficie del medio calentador, tal como el rodillo calentador. En tal caso, el rodillo tensor debe ser repelente al adhesivo termico, ya que actuarla sobre la superficie del precinto provista de cola termica.The sealing belt may also comprise a tension roller, which forces the seal to contact a larger surface of the heating medium, such as the heating roller. In this case, the tension roller must be repellent to the thermal adhesive, since it acts on the surface of the seal provided with thermal glue.

Segun otra opcion, alguno de los rodillos de la gula de paso puede estar tambien provisto de medios de calentamiento para dar al precinto una temperatura minima de operacion previa al contacto con el medio calefactor.According to another option, some of the rollers of the passage can also be provided with heating means to give the seal a minimum operating temperature prior to contact with the heating medium.

Segun la invention tambien estan previstos medios de separacion del precinto de los medios calefactores, de modo que el precinto quede alejado de dichos medios calefactores cuando no esta en movimiento o en fase de actividad.According to the invention, means for separating the seal from the heating means are also provided, so that the seal is removed from said heating means when it is not in motion or in the activity phase.
