Abstract

The invention relates to a fishing tackle and net hauling reel. Haulers are used to cast or raise nets in a fishing vessel. The motorised pulleys or reels of said haulers comprise a metallic body that is coated with an elastomer or rubber material which is in contact with the net and which, upon rotation of the reel, hauls said net. The abrasion of the nets against the rubber coating causes wear to said coating such that it needs to be changed. According to the invention, the reel of the hauler is completely metallic and does not require a rubber coating since it operates perfectly and fulfils its function without causing wear, breakages or snags owing to the fact that the metallic surface thereof is equipped with radially-disposed blades (4) on each of the half-pulleys, such that at least two floats can be provided between each two consecutive blades. The pulley penetration angle is approximately 45°.

Description

CARRETE DE HALADOR DE REDES Y APAREJOS DE PESCA OBJETO DE LA INVENCIÓN REEL OF NETWORK FINDER AND FISHING MATTERS OBJECT OF THE INVENTION
La presente invención, según lo expresa el enunciado de esta memoria descriptiva, se refiere a un carrete de halador de redes y aparejos de pesca, estando el carrete o polea motorizado y montado en un soporte suspendido de la grúa del barco de pesca, presentando este carrete unas características relevantes y ventajosas frente a los que se utilizan con el mismo fin y que pueden considerarse de los de su tipo.The present invention, as stated in the description of this specification, refers to a fishing net and fishing tackle reel, the reel or pulley being motorized and mounted on a suspended support of the fishing boat crane, presenting this reel relevant and advantageous features compared to those used for the same purpose and which can be considered of its kind.
ANTECEDENTES DE LA INVENCIÓNBACKGROUND OF THE INVENTION
Es conocida la utilización de haladores para largar o para subir las redes en un barco de pesca. El tambor o polea que realiza esta operación y que tiene forma de yo-yo, está conformado por un cuerpo metálico revestido de un material de goma que en contacto con la red permite, al girar el carrete, el arrastre tanto de la red como de la relinga con los flotadores.The use of hackers to start or climb the nets on a fishing boat is known. The drum or pulley that performs this operation and which is in the form of a yo-yo, is made up of a metal body covered with a rubber material that, in contact with the net, allows, as the reel turns, the drag of both the net and the cockpit with the floats.
Evidentemente, con el sistema actual de carretes engomados, la abrasión de las redes contra la goma origina un desgaste de dicho recubrimiento, de tal forma que ello obliga a cambiarlo. Este desgaste se mantenía normalmente hasta que apareciese la parte metálica del carrete y obligaba a cambiar el tambor o carrete. En la medida en que los haladores se fabricaban de mayor potencia, se ha ido teniendo que aumentar el tamaño de los carretes, por lo que el cambio de estos carretes en el mar por el desgaste del recubrimiento de goma, ha sido motivo de muchos accidentes al ser un elemento muy pesado y de volumen considerable.Obviously, with the current system of gummed reels, the abrasion of the nets against the rubber causes wear of said coating, in such a way that it forces to change it. This wear was normally maintained until the metal part of the reel appeared and forced to change the drum or reel. To the extent that the hackers were manufactured of greater power, it has been having to increase the size of the reels, so the change of these reels at sea due to the wear of the rubber coating, has been the cause of many accidents Being a very heavy element and of considerable volume.
Además, la abrasión existente entre el engomado y las redes, originaba también el desgaste y envejecimiento de las redes al ser inevitables los deslizamientos de las mismas. Debido también a estos deslizamientos, al salir más la relinga del corcho que la de cadena, se descuadraban las redes produciéndose roturas .In addition, the abrasion between the gummed and the nets, also caused the wear and aging of the nets, since the landslides are inevitable. Also due to these landslides, when the cork cockpit is pulled out more than the chain, the networks causing breakage.
Por lo general, el ángulo que presentan las paredes laterales del carrete en forma de yo-yo es de 50° a 65°, preferentemente entre 57° y 58° y siempre disponiéndose del cuerpo metálico y del recubrimiento de goma, ángulo que es suficiente para realizar el arrastre de la red.In general, the angle of the yo-yo-shaped side walls of the reel is 50 ° to 65 °, preferably between 57 ° and 58 ° and always having the metal body and the rubber coating, an angle that is sufficient to carry out the network drag.
Se ha intentado el diseño y construcción de carretes haladores sin la utilización de recubrimientos de goma, las soluciones no han sido satisfactorias dado el ángulo de penetración de las paredes laterales del cuerpo halador, del orden de 50 a 60° como hemos indicado anteriormente.The design and construction of pulling reels has been attempted without the use of rubber coatings, the solutions have not been satisfactory given the angle of penetration of the side walls of the pulling body, of the order of 50 to 60 ° as we have indicated previously.
En el Modelo de Utilidad 200301142 y como solución al problema del mantenimiento de la polea, la misma se constituye mediante una estructura metálica que presenta cajeras o rebajes como zonas de ubicación y asentamiento de unos tacos desmontables que permiten la reparación de la polea sin que sea necesario desmontarla, puesto que basta con sustituir los tacos deteriorados. Estos tacos van sujetos individualmente y están constituidos por una placa metálica recubierta del elastómero de características antiabrasivas .In the Utility Model 200301142 and as a solution to the pulley maintenance problem, it is constituted by a metal structure that presents pockets or recesses as areas of location and settlement of removable plugs that allow the repair of the pulley without it being it is necessary to disassemble it, since it is enough to replace the damaged studs. These studs are individually attached and consist of a metal plate coated with the elastomer with anti-abrasive characteristics.
Aunque pudiera parecer que el dispositivo objeto del modelo de utilidad 200301142 mejora las disposiciones anteriores, lo cierto es que el problema sigue existiendo, dado que en lugar de cambiar el carrete cuando se gaste la goma, se cambia un conjunto de tacos formados por planchas metálicas trapezoidales recubiertas de goma. En este caso la goma se sigue gastando incluso con más rapidez que cuando el carrete es engomado en su totalidad. En la práctica, este sistema preconizado en el modelo de utilidad antes mencionado, ha sido abandonado por los armadores, habida cuenta de que el engomado total del carrete tiene mayor duración que los carretes con tacos de los señalados en dicho modelo. En los sistemas de engomado total o en el sistema que utiliza tacos engomados, las redes se deslizan al ser haladas gastando en mayor o menor grado el engomado y las mismas redes, con lo que consecuentemente se descuadran, retrasándose el halado de la relinga del corcho con respecto a los paños y a veces retrasándose el halado de la cadena, originándose unas tensiones en las redes que acaban por romperse .Although it may seem that the device object of utility model 200301142 improves the above provisions, the truth is that the problem still exists, since instead of changing the reel when the rubber is worn, a set of studs formed by metal plates is changed rubber coated trapezoidal. In this case the rubber is still spent even faster than when the reel is gummed in its entirety. In practice, this system recommended in the aforementioned utility model, has been abandoned by the shipowners, given that the total gumming of the reel has a longer duration than the reels with studs of those indicated in said model. In total gumming systems or in the system that uses rubberized cues, the nets slide when pulled by spending the gumming and the same nets to a greater or lesser degree, which consequently is taken care of, delaying the pull of the cork cockpit with respect to the cloths and sometimes delaying the pulling of the chain, causing tensions in the networks that end up breaking.
DESCRIPCIÓN DE LA INVENCIÓN En líneas generales, el carrete de halador de redes y aparejos de pesca, objeto de la presente invención, presenta unas características que solucionan perfectamente los problemas señalados anteriormente, estando definido por un cuerpo totalmente metálico con sus paredes inclinadas para formar un ángulo de penetración de aproximadamente 45°. Además, la superficie del carrete o polea está provista de paletas en correspondencia con sus generatrices, las cuales se encuentran uniformemente distribuidas en sentido angular y de forma que las que se encuentren en una de las mitades de la polea quedan desfasadas centralmente respecto de las dos consecutivas del lado opuesto.DESCRIPTION OF THE INVENTION In general, the fishing net and fishing tackle reel, object of the present invention, has characteristics that perfectly solve the problems indicated above, being defined by a totally metallic body with its inclined walls to form a penetration angle of approximately 45 ° . In addition, the surface of the reel or pulley is provided with pallets in correspondence with its generatrices, which are evenly distributed angularly and so that those that are in one of the pulley halves are centrally offset with respect to the two consecutive on the opposite side.
Las paletas metálicas tienen forma general troncopiramidal de paredes laterales definidas por planos radiales y con la superficie lfibre en rampa ascendente, siendo de notable mayor altura en la zona radialmente más alejada de la polea. La arista correspondiente al vértice libre de la forma trapecial de los laterales de la paleta, se encuentra muy redondeada para facilitar la entrada de la red y demás aparejos de pesca. El número de paletas está calculado de forma que se crea un espacio entre paletas, en la zona radialmente más alejada del eje, en el que al menos entre un conjunto de dos flotadores, de modo que en su movimiento vaya halando la relinga con los flotadores, entrando la red paralelamente sin descuadrarse, con lo que se evitan así las roturas.The metal vanes have a general truncated pyramid shape of lateral walls defined by radial planes and with the free surface in ascending ramp, being of notable greater height in the radially furthest area of the pulley. The edge corresponding to the free vertex of the trapecial shape of the sides of the paddle, is very rounded to facilitate the entry of the net and other fishing tackle. The number of vanes is calculated in such a way that a space between pallets is created, in the area radially furthest from the axis, in which at least between a set of two floats, so that in their movement the cockpit is pulled with the floats , entering the network in parallel without neglecting, thereby avoiding So breaks.
Entre paletas, en la zona baja o próxima al cuello de la polea, se considera el tamaño de la malla de la cadena, de forma que trabajen como barboten, evitándose corrimientos .Between pallets, in the lower area or near the neck of the pulley, the size of the chain mesh is considered, so that they work as a slip, avoiding run-off.
Con esta disposición se consigue que tanto la red, la cadena, como los flotadores se halen paralelamente, sujetándose la red en el carrete por el ángulo de 45° formado entre las piezas trapezoidales sin ninguna dificultad.With this arrangement it is achieved that both the net, the chain, and the floats are pulled in parallel, the net being held on the reel by the angle of 45 ° formed between the trapezoidal pieces without any difficulty.
De eta manera se elimina el gasto producido por los engomados, se evitan los desmontajes y asimismo se evita el desgaste de las redes por abrasión, halándose éstas con mayor rapidez y ganando tiempo la maniobra y consecuentemente se mejora el rendimiento.In this way, the expense produced by gumming is eliminated, disassembly is avoided and abrasion of the networks is also avoided by abrasion, these being faster and gaining time and consequently the performance is improved.
