The purpose of the present patent application is to register a process for the manufacture of a round textile sling that incorporates notable innovations and advantages.
Más concretamente, la invención propone el desarrollo de una eslinga textil redonda que está prevista para ser utilizada en el levantamiento y manipulación de grandes cargas, aportando una mayor resistencia al desgaste con respecto a las eslingas convencionales. More specifically, the invention proposes the development of a round textile sling that is intended for use in lifting and handling large loads, providing greater wear resistance with respect to conventional slings.
ANTECEDENTES DE LA INVENCIÓN 10 BACKGROUND OF THE INVENTION 10
Las eslingas textiles redondas son utilizadas en el levantamiento de grandes cargas, estando habitualmente constituidas por un núcleo determinado de hilos de alta resistencia cubiertos en su totalidad por un tejido tubular textil. Éstas se confeccionan según una longitud predeterminada y en forma de aro o rectilínea con gazas o bucles cerrados dispuestos en dos extremos opuestos. 15 Round textile slings are used to lift large loads, usually consisting of a specific core of high-strength threads covered entirely by a textile tubular fabric. These are made according to a predetermined length and in the form of a ring or rectilinear with gauges or closed loops arranged at two opposite ends. fifteen
Durante la vida útil de una eslinga redonda ésta está sometida a un deterioro originado principalmente por el rozamiento, ya sea por el contacto directo de la eslinga con la carga a manipular así como el contacto de la misma con el suelo, de modo que este rozamiento provoca un desgaste en la superficie exterior o envoltura de la eslinga, especialmente en los cantos u orillos de ésta, de modo que se reduce la vida útil de la eslinga, y con el 20 consiguiente riesgo de provocar un accidente en el caso de rotura de la eslinga durante su utilización, por lo que existe una necesidad de mejorar la configuración y proceso de fabricación de las eslingas actualmente conocidas en la técnica anterior. During the life of a round sling it is subject to deterioration caused mainly by friction, either by the direct contact of the sling with the load to be handled as well as its contact with the ground, so that this friction it causes wear on the outer surface or wrap of the sling, especially in its edges or edges, so that the life of the sling is reduced, and with the consequent risk of causing an accident in the event of breakage of the sling during use, so there is a need to improve the configuration and manufacturing process of the slings currently known in the prior art.
DESCRIPCIÓN DE LA INVENCIÓN DESCRIPTION OF THE INVENTION
La presente invención se ha desarrollado con el fin de proporcionar un procedimiento para la 25 fabricación de una eslinga que se configura como una novedad dentro del campo de aplicación y resuelva los inconvenientes anteriormente mencionados, aportando, además, otras ventajas adicionales que serán evidentes a partir de la descripción que se acompaña a continuación.

Es por lo tanto un objeto de la presente invención proporcionar un nuevo procedimiento para 30 la fabricación de una eslinga textil redonda, estando dicha eslinga prevista para el levantamiento y manipulación de cargas que comprende una núcleo interior provisto de una pluralidad de hilos sinfín que transcurren longitudinalmente y paralelos entre sí y una envoltura exterior hecha de un material textil que recubre dicho núcleo interior. Más en particular, durante la etapa de tejido de la envoltura exterior se aplica en la urdimbre de 35 dicha envoltura unos hilos de alta resistencia con una base de silicona y posteriormente se aplica una dispersión de una mezcla de poliuretano y un catalizador con una base de solución de poliisocianato alifático. It is therefore an object of the present invention to provide a new process for the manufacture of a round textile sling, said sling being provided for lifting and handling loads comprising an inner core provided with a plurality of longitudinally running endless threads. and parallel to each other and an outer shell made of a textile material that covers said inner core. More particularly, during the woven stage of the outer shell, high strength threads with a silicone base are applied to the warp of 35 and subsequently a dispersion of a mixture of polyurethane and a catalyst with a base of aliphatic polyisocyanate solution.
En esta memoria se entiende por eslinga redonda aquella que presenta una sección transversal de contorno circular, sensiblemente circular o elíptico. 40 In this report, round sling is understood as one that has a circular, substantially circular or elliptical cross section. 40
La finalidad de tales hilos con material de silicona junto al urdimbre es proteger la eslinga redonda de cortes y/o daños debidos al posible contacto de la misma con cantos, aristas u otras superficies susceptibles de rasgar o dañar la eslinga. The purpose of such threads with silicone material next to the warp is to protect the round sling from cuts and / or damage due to the possible contact of the same with edges, edges or other surfaces susceptible to tearing or damaging the sling.
Según otro aspecto de la invención, la dispersión de la mezcla de poliuretano y un catalizador con una base de solución de poliisocianato alifático se lleva a cabo mediante un baño de inmersión de la envoltura exterior. According to another aspect of the invention, the dispersion of the mixture of polyurethane and a catalyst with a base of aliphatic polyisocyanate solution is carried out by means of an immersion bath of the outer shell.
De forma ventajosa, tras la dispersión de la mezcla de poliuretano se aplica una etapa adicional de foulardado. De este modo, permite que la impregnación de la envoltura exterior 5 tubular sea tanto por su parte exterior como interior, asegurando así una protección antiabrasiva. Posteriormente a la etapa adicional de foulardado se lleva a cabo una etapa de secado, que permite fijar la red tridimensional conformada previamente en el presecado para proporcionar mayor estabilidad y por consiguiente mayor eficacia antiabrasiva. Advantageously, after dispersion of the polyurethane mixture, an additional stamping stage is applied. In this way, it allows the impregnation of the tubular outer shell 5 to be both on its outer and inner part, thus ensuring anti-abrasive protection. A drying stage is carried out after the additional cutting stage, which allows the three-dimensional network previously formed in the pre-drying to be fixed to provide greater stability and consequently greater anti-abrasive efficiency.
Es también otro objeto de la invención proporcionar un eslinga textil redonda prevista para el 10 levantamiento y manipulación de cargas que comprende una núcleo interior provisto de una pluralidad de hilos de urdimbre que transcurren longitudinalmente y paralelos entre sí y una envoltura exterior tubular textil, caracterizada por el hecho de que la envoltura exterior tubular textil incluye una pluralidad de hilos de alta resistencia con una base de silicona que transcurren paralelos a los hilos de urdimbre que forman parte de la propia envoltura exterior 15 tubular textil. It is also another object of the invention to provide a round textile sling intended for lifting and handling loads comprising an inner core provided with a plurality of warp threads that run longitudinally and parallel to each other and a textile tubular outer shell, characterized by the fact that the textile tubular outer shell includes a plurality of high strength threads with a silicone base that run parallel to the warp threads that are part of the textile tubular outer shell 15 itself.

DESCRIPCIÓN DE UNA REALIZACIÓN PREFERENTE DESCRIPTION OF A PREFERRED EMBODIMENT
A la vista de las mencionadas figuras y, de acuerdo con la numeración adoptada, se puede observar en ellas un ejemplo de realización preferente de la invención, la cual comprende 30 las partes y elementos que se indican y describen en detalle a continuación. In view of the aforementioned figures and, according to the numbering adopted, an example of a preferred embodiment of the invention can be observed therein, which comprises the parts and elements indicated and described in detail below.
Haciendo particular referencia a las figuras 1 y 2, un procedimiento para la fabricación de una eslinga textil (1), por ejemplo, constituida por un tramo alargado (11) provisto en sus dos extremos con bucles cerrados (12) que servirán como zonas de enganche, se detalle a continuación. Tal como se muestra en la figura 3, la eslinga textil (1) está constituida por un 35 núcleo interior (2) provisto de una pluralidad de hilos sinfín que transcurren longitudinalmente y paralelos entre sí y una envoltura exterior (3) que envuelve dicho núcleo interior (2). With particular reference to Figures 1 and 2, a process for the manufacture of a textile sling (1), for example, constituted by an elongated section (11) provided at its two ends with closed loops (12) that will serve as areas of hitch, detailed below. As shown in Figure 3, the textile sling (1) is constituted by an inner core (2) provided with a plurality of endless threads that run longitudinally and parallel to each other and an outer shell (3) that wraps said core interior (2).
Para su fabricación, y haciendo particular referencia a la envoltura exterior (3) en una primera etapa (10) se aplica en su urdimbre (formada por una pluralidad de hilos (4) de alta 40 resistencia) unos hilos de material de silicona de alta resistencia (5) y posteriormente se aplica una etapa de dispersión (20) de una mezcla de poliuretano y un catalizador con una base de solución de poliisocianato alifático. For its manufacture, and with particular reference to the outer shell (3) in a first stage (10), its threads of high silicone material are applied in its warp (formed by a plurality of threads (4) of high strength). resistance (5) and subsequently a dispersion step (20) of a mixture of polyurethane and a catalyst with a base of aliphatic polyisocyanate solution is applied.
La etapa de dispersión (20) de la mezcla de poliuretano y un catalizador con una base de solución de poliisocianato alifático se lleva a cabo mediante un baño de inmersión de la envoltura exterior. The dispersion step (20) of the mixture of polyurethane and a catalyst with a base of aliphatic polyisocyanate solution is carried out by means of an immersion bath of the outer shell.
Seguidamente, tras la etapa de dispersión (20) de la mezcla de poliuretano se aplica una etapa adicional de foulardado (30) donde se hace pasar la eslinga a través de una serie de 5 cilindros de presión para reducir el volumen líquido presente en ésta y procedente del baño. Posteriormente se realiza una etapa de presecado (40) y una etapa de secado (50) que permiten una buena reticulación de la dispersión de poliuretano para lograr unas propiedades óptimas para ofrecer la máxima protección. En la etapa de presecado (40) se forma la red tridimensional de las cadenas poliméricas, por lo que es importante mantener 10 un rango de temperaturas adecuado, por ejemplo, entre 110ºC y 130ºC durante un periodo de 30 a 45 segundos aproximadamente, así como una velocidad de paso de la cinta para lograr una red tridimensional adecuada. Then, after the dispersion stage (20) of the polyurethane mixture, an additional fouling stage (30) is applied where the sling is passed through a series of 5 pressure cylinders to reduce the liquid volume present in it and coming from the bathroom. Subsequently, a pre-drying stage (40) and a drying stage (50) are carried out that allow a good cross-linking of the polyurethane dispersion to achieve optimum properties to offer maximum protection. In the pre-drying stage (40) the three-dimensional network of the polymer chains is formed, so it is important to maintain a suitable temperature range, for example, between 110 ° C and 130 ° C for a period of approximately 30 to 45 seconds, as well as a speed of passage of the tape to achieve a suitable three-dimensional network.
En la fase de secado, que tiene lugar en un rango de temperaturas de 160-180ºC aproximadamente, se fija la red tridimensional a nivel molecular para que se mantenga 15 estable y de este modo obtener la mayor eficacia antiabrasiva. In the drying phase, which takes place in a temperature range of approximately 160-180 ° C, the three-dimensional network is set at the molecular level so that it remains stable and thus obtain the highest anti-abrasive efficiency.
Los detalles, las formas, las dimensiones y demás elementos accesorios, así como los materiales empleados en la fabricación de la eslinga obtenida con el procedimiento de la invención podrán ser convenientemente sustituidos por otros que sean técnicamente equivalentes y no se aparten de la esencialidad de la invención ni del ámbito definido por las 20 reivindicaciones que se incluyen a continuación. The details, shapes, dimensions and other accessory elements, as well as the materials used in the manufacture of the sling obtained with the process of the invention may be conveniently replaced by others that are technically equivalent and do not depart from the essentiality of the invention or the scope defined by the 20 claims that are included below.
