Description

DESCRIPCIÓNDESCRIPTION

Mandril para bobinas.Mandrel for coils.

Objeto de la invención.Object of the invention.

El objeto de la invención es un mandril para bobinas, que comprende un tubo fabricado con cartón, fibra de vidrio, fibra de carbono, plástico, acero, aluminio o cualquier otro material adecuado para bobinar sobre el mismo papel, film o cualquier otro material.The object of the invention is a mandrel for coils, comprising a tube made of cardboard, fiberglass, carbon fiber, plastic, steel, aluminum or any other material suitable for winding on the same paper, film or any other material.

Este mandril presenta unas características orientadas a reforzar los extremos del mismo con el fin de protegerlo de los golpes o rozaduras producidos cuando en los extremos de este tubo se introducen núcleos, topes o mandriles expansibles, tanto en el momento de utilizarse para bobinar los materiales comentados, como en el momento de desbobinarlos para ser tratados en trabajos como impresión, gofrado, corte, rebobinado en bobinas más pequeñas, etc.This mandrel presents features oriented to reinforce the ends thereof in order to protect it from bumps or scratches produced when the ends of this tube are introduced cores, stops or expandable mandrels, both when used to wind the materials discussed , as at the time of unwinding to be treated in jobs such as printing, embossing, cutting, rewinding in smaller coils, etc.

Campo de aplicación de la invención.Field of application of the invention.

Esta invención es aplicable en el sector dedicado a la fabricación de mandriles para bobinas de productos diversos.This invention is applicable in the sector dedicated to the manufacture of mandrels for coils of various products.

Estado de la técnica.State of the art

Las bobinas de materiales diversos, por ejemplo de lámina de papel o de film plástico, se conforman enrollando el material en cuestión en torno a un mandril conformado por un tubo que además de servir de soporte de la bobina define un pasaje axial para la introducción por sus extremos de núcleos, topes o mandriles expansibles que posibilitan su agarre y manipulación.The coils of various materials, for example of paper sheet or plastic film, are formed by winding the material in question around a mandrel formed by a tube that in addition to serving as the coil support defines an axial passage for the introduction by its ends of cores, stops or expandable mandrels that enable its grip and handling.

La colocación de estos núcleos o topes provocan daños, en muchos casos irreparables, en los extremos del tubo de los mandriles y en poco tiempo dichos mandriles llegan a ser inutilizables para su función inicial. También estos daños pueden provocar riesgos en la seguridad de los tubos al ser alzados mediante puentes grúa o polipastos, al tener la posibilidad de perder la fijación de los topes y caer desde alturas importantes con el peligro del personal responsable de la movilización de las bobinas.The placement of these cores or stops cause damage, in many cases irreparable, at the ends of the tube of the mandrels and in a short time said Mandrons become unusable for their initial function. Also these damages can cause risks in the safety of the tubes when being lifted by means of overhead cranes or hoists, having the possibility of losing the fixation of the stops and falling from important heights with the danger of the personnel responsible for the mobilization of the coils.

El titular de la invención desconoce la existencia de antecedentes de mandriles para bobinas que presenten unas características técnicas, estructurales y constitutivas semejantes a las que presenta el mandril de esta invención y que permitan solucionar el problema planteado.The owner of the invention is unaware of the existence of a history of mandrels for coils that have technical, structural and constitutive characteristics similar to those presented by the mandrel of this invention and that allow to solve the problem posed.

Descripción de la invención.Description of the invention.

El mandril para bobinas, objeto de esta invención, comprende un tubo de cualquier material abierto por los extremos opuestos y que presenta una superficie exterior y una superficie interior.The mandrel for coils, object of this invention, comprises a tube of any material open at opposite ends and having an outer surface and an inner surface.

Con el fin de resolver el problema técnico planteado este mandril comprende en cada uno de los extremos del tubo un protector tubular fabricado con un material adecuado para resistir agresiones físicas y/o químicas, que evita el deterioro de los mencionados extremos del tubo.In order to solve the technical problem posed this mandrel comprises at each end of the tube a tubular protector made of a material suitable to resist physical and / or chemical aggressions, which prevents deterioration of said ends of the tube.

Los protectores tubulares están conformados en un material que presenta una resistencia física y/o química adecuada a la aplicación y uso del mandril, por ejemplo resistencia contra: impactos, abrasión, corrosión, solventes, temperaturas extremas, ácidos u otras sustancias químicas. Algunos de los posibles materiales de fabricación de los protectores tubulares son: elastómero de poliuretano, goma natural, goma sintética, plásticos, acero al carbono, acero inoxidable o elastómeros en general.The tubular protectors are formed in a material that has a physical and / or chemical resistance suitable to the application and use of the mandrel, for example resistance against: impacts, abrasion, corrosion, solvents, extreme temperatures, acids or other chemical substances. Some of the possible materials of manufacture of the tubular protectors are: polyurethane elastomer, natural rubber, synthetic rubber, plastics, carbon steel, stainless steel or elastomers in general.

El tubo presenta en su superficie interior sendos rebajes extremos en los que se encuentran acoplados los protectores tubulares, de modo que en la posición de montaje dichos protectores tubulares presentan una superficie interior coplanaria con la superficie interior del tubo y en uno de sus extremos un reborde exterior que cubre frontalmente el correspondiente extremo del tubo. The tube has on its inner surface two end recesses in which the tubular protectors are coupled, so that in the assembly position said tubular protectors have an interior surface coplanar with the inner surface of the tube and at one of its ends a flange exterior that covers the corresponding end of the tube frontally.

Con las características indicadas los protectores tubulares cubren interior y frontalmente los extremos del tubo del mandril, incrementando su resistencia y consiguientemente la vida útil del mismo.With the indicated characteristics, the tubular protectors cover the ends of the mandrel tube internally and frontally, increasing its resistance and consequently the service life thereof.
