Description
Método de fabricación de un conjunto de base-suela para calzado y conjunto de base-suela fabricado con dicho método.Manufacturing method of a set of base-sole for footwear and set of base-sole manufactured with this method.
La presente invención pertenece al campo técnico de la fabricación de calzado, concretamente a la unión de distintas partes que componen el calzado, hechas con distintos materiales, y más concretamente a la fabricación de conjuntos formados por la unión de una base de caucho y corcho vulcanizados, y una suela de material termoplástico.The present invention belongs to the technical field from the manufacture of footwear, specifically to the union of different parts that make up the footwear, made with different materials, and more specifically to the manufacture of assemblies formed by the union of a vulcanized rubber and cork base, and a sole of thermoplastic material
Hasta la actualidad se ha utilizado la vulcanización de caucho y corcho en la industria del calzado para fabricar diferentes bases, tales como plantas, entreplantas, plataformas, etc. Su forma más conocida es la planta con la que se construye la popular sandalia "Bio".Until now the rubber and cork vulcanization in the footwear industry for manufacture different bases, such as plants, mezzanines, platforms, etc. Its best known form is the plant with which it build the popular "Bio" sandal.
También se utiliza en la industria del calzado el moldeado por inyección de suelas. Esta técnica se puede realizar de dos maneras. O bien fabricando la suela por separado y uniéndola posteriormente a la base en el lugar de manufacturación, que es lo más habitual, o bien inyectando la suela directamente sobre un corte ya montado o sobre una parte del corte que luego se ensambla con el resto, que es lo que se conoce como "inyección directa al corte". A esta segunda técnica correspondería la presente innovación, concretamente al moldeado de una suela de material termoplástico mediante inyección, sobre una base formada por una estructura de caucho y corcho previamente vulcanizada.It is also used in the footwear industry sole injection molding. This technique can be performed. In two ways. Or making the sole separately and joining it subsequently to the base at the place of manufacture, which is what more usual, or by injecting the sole directly on a cut already mounted or on a part of the cut that is then assembled with the rest, which is what is known as "direct injection to cut ". This second technique would correspond to the present innovation, specifically to the molding of a sole of material thermoplastic by injection, on a base formed by a rubber structure and previously vulcanized cork.
Esto no se había conseguido hasta ahora porque dicha estructura presenta serios inconvenientes químicos y estructurales que han hecho desistir de su empleo en este campo.This had not been achieved so far because said structure has serious chemical disadvantages and structural factors that have given up their employment in this field.
El primer inconveniente es su naturaleza química, el caucho es un termorrígido, no vuelve a fundirse después de su vulcanización, como sí ocurre con otros materiales, los llamados termoplásticos. Es decir no se une la estructura de caucho y corcho a la materia inyectada por fusión sino por la intermediación de la capa de cola que se da sobre la superpie a inyectar, previo lavado con halógenos que eliminan los aceites empleados en su composición.The first drawback is its nature chemistry, rubber is a thermo-rigid, it does not melt again after of its vulcanization, as with other materials, called thermoplastics. In other words, the rubber structure is not attached and cork to the matter injected by fusion but by the intermediation of the glue layer that occurs on the super skin inject, after washing with halogens that remove oils employees in its composition.
En cuanto a los inconvenientes estructurales, se presentan en forma de variaciones en volumen y en rigidez de las unidades fabricadas industrialmente, variaciones que hacen imposible su empleo en técnicas que exijan un alto grado precisión.As for the structural inconveniences, it present in the form of variations in volume and stiffness of industrially manufactured units, variations that make it impossible its use in techniques that require a high degree of precision.
Estas diferencias entre unas unidades y otras se debe a sus componentes. Tanto el corcho como el caucho siguen reaccionando a los cambios ambientales después de su extracción de la naturaleza, lo que les convierte en muy inestables y hace muy complicada su medición. Remesas distintas de corcho producen volúmenes distintos respecto a su peso. Remesas distintas de caucho pueden dar valores distintos de rigidez al producto acabado, pues no son productos sintéticos y reproducibles con exactitud.These differences between some units and others are It owes its components. Both cork and rubber follow reacting to environmental changes after its extraction from nature, which makes them very unstable and makes very Complicated measurement. Remittances other than cork produce different volumes regarding its weight. Remittances other than rubber they can give different values of stiffness to the finished product, because not They are synthetic and reproducible products with accuracy.
Hay, por último, un inconveniente también estructural que es la deficiente cohesión de esta mezcla, que tiende a desmenuzarse con cierta facilidad, lo que debilita los valores de adhesión y restringe seriamente las posibilidades que ofrece un sistema de este tipo.There is, finally, an inconvenience too structural which is the poor cohesion of this mixture, which tends to crumble with some ease, which weakens the values of adhesion and seriously restricts the possibilities offered by a system of this type.
Era por tanto deseable un método que consiguiera una unión eficiente entre bases formadas por estructuras de caucho y corcho vulcanizadas, y suelas de materiales termoplásticos, evitando los inconvenientes existentes en los anteriores sistemas del estado de la técnica.It was therefore desirable a method to get an efficient bond between bases formed by rubber structures and vulcanized cork, and thermoplastic material soles, avoiding the disadvantages existing in the previous state systems of technique
La presente invención resuelve los problemas existentes en el estado de la técnica mediante un método de fabricación de un conjunto base-suela, que puede ser concretamente un conjunto de entreplanta-suela, de planta-suela o de plataforma-suela para calzado, en el cual se realiza la unión de una estructura base que está fabricada con una mezcla de caucho y corcho vulcanizados, con una suela hecha de material termoplástico.The present invention solves the problems existing in the state of the art by a method of manufacture of a base-sole assembly, which can be specifically a mezzanine-sole set, of sole-sole or platform-sole for footwear, in which the union of a base structure is made which is made of a mixture of vulcanized rubber and cork, with a sole made of thermoplastic material.
El método tiene una primera fase de fabricación de la estructura base de caucho y corcho, a la cual se le da forma mediante su vulcanización a altas temperaturas. Posteriormente, a la estructura base se le añaden medios adhesivos que reactivan a una determinada temperatura.The method has a first manufacturing phase of the rubber and cork base structure, which is shaped by vulcanization at high temperatures. Subsequently, to the base structure are added adhesive media that reactivate a certain temperature
Para disminuir al mínimo las posibles variaciones de volumen descritas en los antecedentes de la invención, que suelen presentar estos productos, se mide el volumen exacto de corcho, en lugar de su peso, en la proporción que necesita respecto al caucho y se comprueba el peso final de cada unidad, lo que indica su homogeneidad.To minimize the possible volume variations described in the background of the invention, which usually present these products, the volume is measured exact cork, instead of its weight, in the proportion you need with respect to rubber and the final weight of each unit is checked, which indicates its homogeneity.
Para alcanzar el grado de rigidez ideal para esta técnica, que necesita estructuras con cierta rigidez y estabilidad, se le añade a la mezcla partes proporcionales de estireno, que es un producto sintético que estabiliza la rigidez en unos valores óptimos para el sistema, sin sacrificar su resiliencia.To achieve the ideal degree of stiffness for this technique, which needs structures with some rigidity and stability, proportional parts of styrene, which is a synthetic product that stabilizes stiffness in optimal values for the system, without sacrificing its resilience
En cuanto a la deficiente cohesión de la mezcla se ha solucionado mediante el aumento de la proporción de caucho sobre la de corcho. A mayor proporción de caucho, mayor cohesión, hasta llegar a un equilibrio entre esta y la apariencia tradicional de este tipo de producto.As for the poor cohesion of the mixture has been solved by increasing the proportion of rubber on cork. The higher the proportion of rubber, the greater cohesion, until you reach a balance between this and the traditional appearance of this type of product.
A continuación, la estructura base de caucho y corcho se introduce en un molde que está formado por dos partes. En una primera parte existe un vaciado que puede presentar las diversas formas a dar a la futura suela, y una pestaña que rodea todo el perímetro del vaciado. Una segunda parte cierra sobre la primera, quedando de esta forma el molde cerrado, pudiendo esta segunda parte colocarse y retirarse con facilidad. La estructura base se introduce entre la primera parte y la segunda parte del molde, ejerciendo esta segunda parte presión sobre la estructura base, de tal forma que la pestaña se incrusta en dicha estructura base. Una vez introducida la estructura base y cerrado el molde, se procede a la inyección de un material termoplástico directamente en el vaciado del molde, a la temperatura T, lo que conforma la suela en la estructura base, reactivándose los medios adhesivos y quedando fija dicha suela a la estructura base mediante estos medios adhesivos.Next, the base structure of rubber and Cork is introduced into a mold that is formed by two parts. In a first part there is an emptying that can present the various ways to give the future sole, and a tab that surrounds all the emptying perimeter. A second part closes on the first, the mold being thus closed, this second part being able easily placed and removed. The base structure is introduced between the first part and the second part of the mold, exercising this second part pressure on the base structure, so that the tab is embedded in said base structure. Once the base structure and closed the mold, we proceed to the injection of a thermoplastic material directly in the mold emptying, to the temperature T, which makes up the sole in the base structure, the adhesive media being reactivated and said sole being fixed to the base structure by means of these adhesive means.
Mediante este molde, se consigue evitar cualquier tipo de fugas de material termoplástico en la inyección, ya que la pestaña está dispuesta alrededor de todo el perímetro del vaciado que contiene el material fundido, y actúa a modo de barrera de contención.Through this mold, you can avoid any type of leakage of thermoplastic material in the injection, since the tab is arranged around the entire perimeter of the emptying that contains molten material, and acts as a barrier of containment.
Este método permite nuevas posibilidades en el diseño de las suelas, al no estar sujeto a las restricciones en las formas que exige su fabricación por separado, donde la suela debe tener una estructura lo suficientemente compacta y lineal como para poder ser manipulada posteriormente. Esta es la ventaja más clara sobre los métodos tradicionales, la capacidad de innovación estética de una parte del calzado que cada vez goza de más importancia.This method allows new possibilities in the design of the soles, not being subject to restrictions on forms that require its manufacture separately, where the sole must have a compact and linear structure enough to can be manipulated later. This is the clearest advantage. about traditional methods, the capacity for aesthetic innovation of a part of footwear that is increasingly important.
Este método también proporciona otra serie de ventajas sobre los existentes en el estado de la técnica, como es una adecuada fijación de la suela a este tipo de material. Además se simplifica el proceso de manufacturación en las fábricas, ya que se reciben unidos dos elementos distintos.This method also provides another series of advantages over those existing in the state of the art, as is proper fixing of the sole to this type of material. Also I know simplifies the manufacturing process in factories, since it They receive two different elements together.

El objeto de la presente invención es un método de fabricación de un conjunto base-suela para calzado mediante inyección, que puede consistir concretamente en un conjunto planta-suela, un conjunto entreplanta-suela, o un conjunto plataforma-suela.The object of the present invention is a method manufacturing of a base-sole assembly for injection shoes, which can consist specifically of a sole-sole set, a set mezzanine-sole, or a set platform-sole.
Mediante este método se realiza la unión entre una estructura base 1, hecha de una mezcla de caucho y corcho previamente vulcanizados, y una suela 2 hecha de un material termoplástico. Este material termoplástico puede ser preferentemente poliuretano termoplástico o TPU, o policloruro de vinilo o PVC.Through this method the union between a base structure 1, made of a mixture of rubber and cork previously vulcanized, and a sole 2 made of a material thermoplastic This thermoplastic material may preferably be thermoplastic polyurethane or TPU, or polyvinyl chloride or PVC.
En la primera etapa del método se fabrica la estructura base 1 mediante una mezcla formada por caucho y corcho en diferentes proporciones, dependiendo del grado de cohesión que se desee en dicha estructura base 1, dado que el aumento de la proporción de caucho aumentará la cohesión entre las partículas de la estructura base 1.In the first stage of the method the base structure 1 by a mixture formed by rubber and cork in different proportions, depending on the degree of cohesion that desired in said base structure 1, since the increase in rubber ratio will increase the cohesion between the particles of the base structure 1.
Posteriormente, a la estructura base 1 se le añaden medios adhesivos, los cuales preferentemente son de tipo hot-melt, y se reactivan por medio de calor, a una determinada temperatura T.Subsequently, the base structure 1 is given add adhesive media, which are preferably of type hot-melt, and they are reactivated by means of heat, at a certain temperature T.
De acuerdo con una realización particular del método, antes de la adición de estos medios adhesivos se puede realizar una halogenación a la estructura base 1, lo cual favorece la unión posterior del material termoplástico de la suela 2.According to a particular embodiment of the method, before the addition of these adhesive means can be perform a halogenation to the base structure 1, which favors the posterior union of the thermoplastic material of the sole 2.
Después de añadir los medios adhesivos, la estructura base 1 se introduce en un molde 3 que está formado por una primera parte 4 y una segunda parte 7 que cierra sobre la primera parte 4. La primera parte tiene un vaciado 5 con las diversas formas que se le dará a la suela 2, y una pestaña 6 que rodea todo el perímetro de dicho vaciado 5.After adding the adhesive media, the base structure 1 is introduced into a mold 3 which is formed by a first part 4 and a second part 7 that closes on the first part 4. The first part has an emptying 5 with the various forms that will be given to sole 2, and a tab 6 that surrounds the entire perimeter of said emptying 5.
La figura 1 muestra de forma esquemática esta etapa, en la que, una vez introducida la estructura base 1 entre la primera parte 4 y la segunda parte 7 del molde 3, la segunda parte 7 ejerce presión sobre la estructura base 1, de tal forma que la pestaña 6 se incrusta en dicha estructura base 1.Figure 1 shows schematically this stage, in which, once the base structure 1 has been introduced between the first part 4 and the second part 7 of the mold 3, the second part 7 exerts pressure on the base structure 1, so that the tab 6 is embedded in said base structure 1.
De forma preferente, la pestaña tiene una altura de 1,5 milímetros y un grosor de 1 milímetro.Preferably, the flange has a height 1.5 millimeters and a thickness of 1 millimeter.
En la siguiente etapa se realiza una inyección de un material termoplástico directamente en el molde 3 a la temperatura T, que se aloja en el vaciado 5 y conforma la suela 2.In the next stage an injection is made of a thermoplastic material directly in the mold 3 to the temperature T, which is housed in the dump 5 and forms the sole 2.
Al entrar el material termoplástico a la temperatura T de reactivación de los medios adhesivos, éstos se reactivan realizando su función de pegado, quedando fijada la suela 2 a la estructura base 1 mediante estos medios adhesivos.When the thermoplastic material enters the reactivation temperature T of the adhesive media, these are they reactivate performing their gluing function, the sole being fixed 2 to the base structure 1 by these adhesive means.
Al haber quedado incrustada la pestaña 6 en la estructura base 1 se evitan las posibles fugas del material termoplástico y el derrame de éste sobre dicha estructura base 1, lo que proporciona un acabado correcto de la suela 2, y con ella del conjunto base-suela.Having tab 6 embedded in the base structure 1 avoids possible material leaks thermoplastic and its spillage on said base structure 1, what which provides a correct finish of the sole 2, and with it the base-sole set.
Otro objeto de la presente invención es el propio conjunto base-suela para calzado obtenido empleando el método anterior. Así, tal y como se puede observar en la figura 2, el conjunto está formado por una estructura base 1 hecha de una mezcla de caucho y de corcho, y por una suela 2 hecha de un material termoplástico unida a la estructura base 1 mediante medios adhesivos, los cuales se reactivan a una determinada temperatura T.Another object of the present invention is the own base-sole set for footwear obtained using the previous method. Thus, as can be seen in Figure 2, the assembly is formed by a base structure 1 made of a mixture of rubber and cork, and by a sole 2 made of a thermoplastic material attached to the base structure 1 by adhesive means, which are reactivated to a certain T. temperature
