Abstract

The present invention relates to a self-threader, longitudinal rolling mill with improvements that allows to optimize the rolling process and make it more comfortable and safe. To do this, two systems have been coupled, on both sides of the machine, consisting of a series of elements, which enable the movement of the upper roller with respect to the lower roller, indispensable to adapt to different thicknesses of mass, in a much more dynamic and comfortable than in current laminators. Likewise, a plastic piece has been fitted between the dough input roller and the lower one, which, by copying both profiles, allows the lower roller to be able to catch the dough at the start of production, since it prevents it from sliding between both rolls, and with that it has to be the operator that manually must guide it, thus increasing the safety of this type of machines.

La presente invencion se refiere a un auto-enhebrador pensado para la industria alimentaria, particularmente para laminadores longitudinales de masa, que contiene diversos elementos mecanicos que permiten facilitar el proceso de laminacion de forma que resulte mas comodo y seguro. Pertenece al sector de la ingenierla mecanica y mas concretamente al de maquinaria alimentaria.The present invention relates to a self-threader designed for the food industry, particularly for longitudinal dough sheeters, which contains various mechanical elements that facilitate the rolling process so that it is more comfortable and safe. It belongs to the sector of mechanical engineering and more specifically to food machinery.

ANTECEDENTES DE LA INVENCIONBACKGROUND OF THE INVENTION

En la actualidad son muchas las aplicaciones de los laminadores en la industria alimentaria. Este tipo de maquinas permiten laminar y homogenizar el espesor y la textura de la masa que pasa por su interior sustituyendo el trabajo manual por un sistema mecanico que presenta multiples ventajas como disminuir los costos de produccion, reducir los tiempos de procesamiento o asegurar la uniformidad del producto en tamano.At present there are many applications of rolling mills in the food industry. This type of machines allow to laminate and homogenize the thickness and texture of the dough that passes through its interior, replacing the manual work with a mechanical system that presents multiple advantages such as reducing production costs, reducing processing times or ensuring uniformity of the product in size.

La maquina en su conjunto esta formada por un bastidor metalico que aloja dos rodillos de acero encargados de laminar y homogenizar el espesor y la textura de la masa que pasa por su interior. Para conseguir este proposito, el conjunto equipa una serie de pinones y engranajes encargados de transmitir el movimiento desde el moto reductor general hasta sendos rodillos, a traves de una transmision pinon-cadena; transmitiendo el movimiento de manera directa al rodillo laminador inferior y a la cinta de entrada de masa, siendo este primer rodillo el que, a traves de una transmision pinon cadena primero, y dos engranajes rectos despues, transmite el movimiento al rodillo laminador superior.The machine as a whole is formed by a metal frame that houses two steel rollers in charge of rolling and homogenizing the thickness and texture of the mass passing through its interior. To achieve this purpose, the set equips a series of pinions and gears in charge of transmitting the movement from the general reducer motorcycle to individual rollers, through a pinion-chain transmission; transmitting the movement directly to the lower rolling roller and to the dough input belt, this first roller being the one that, through a transmission pinned chain first, and two straight gears later, transmits the movement to the upper rolling roller.

Estan compuestos de diferentes partes, los elementos constitutivos de la propia maquina, como los soportes laterales de aluminio o palastros que son los elementos que sirven de bastidor portante para el resto de conjunto, los elementos constitutivos como son los rodillos laminadores y rascadores que son elementos que entran en contacto directamente con la masa y se encargan de laminaria y darle las caracterlsticas necesarias, los elementos de transmision y regulation que son los encargados de transmitir el movimiento desde el moto reductor a los diferentes elementos moviles asl como su regulacion y puesta a punto, y la cinta de entrada que se encarga de transportar la masaThey are composed of different parts, the constituent elements of the machine itself, such as the aluminum lateral supports or palastros that are the elements that serve as supporting frame for the rest of the set, the constituent elements such as the rollers and scrapers that are elements who enter contact directly with the mass and take care of the laminaria and give it the necessary characteristics, the transmission and regulation elements that are in charge of transmitting the movement from the motorcycle reducer to the different mobile elements as well as its regulation and tuning, and the entrance tape that is responsible for transporting the dough

A la hora de disenar un laminador alimentario es muy importante tener en cuenta la necesidad de obtener diversos espesores en la masa, debido a este requerimiento, los rodillos superior e inferior resultan ser regulables en altura entre si mediante un sistema de volante-husillo que lo permite. Esta forma de regulacion esta en la actualidad muy limitada. El mecanismo esta formado por dos volantes, uno a cada lado del rodillo superior del laminador, cada uno de ellos mueve, mediante una varilla roscada, el soporte de acero que sirve de sustento a cada extremo del eje del rodillo superior a traves de unas correderas fijas en la bancada, dicho patln y las correderas estan ligeramente separadas de forma que se permite el movimiento, pero este no se realiza de forma totalmente satisfactoria, teniendo que emplear mucho esfuerzo para variar la position del rodillo, faltando precision en la calibration e incluso pudiendo haber colision entre ambas piezas lo que puede originar virutas debido al roce.When designing a food mill, it is very important to take into account the need to obtain different thicknesses in the mass, due to this requirement, the upper and lower rollers are adjustable in height by means of a flywheel-spindle system that It allows. This form of regulation is currently very limited. The mechanism is formed by two wheels, one on each side of the upper roller of the rolling mill, each of them moves, by means of a threaded rod, the steel support that serves as support to each end of the axis of the upper roller through some sliding fixed in the bed, said pad and slides are slightly separated so that movement is allowed, but this is not done in a completely satisfactory, having to use much effort to vary the position of the roller, lacking accuracy in the calibration and even There may be collision between both parts which can cause chips due to friction.

Otro problema que encontramos en el diseno de los laminadores alimentarios se encuentra a la hora de comenzar la production. En el proceso de lamination la masa se introduce en el laminador a traves de la cinta de entrada para posteriormente ser situada sobre el rodillo inferior, circulando entre el rodillo inferior y superior y saliendo fuera del laminador con un espesor menor al inicial. El problema reside en el impedimento mecanico de poder acercar el rodillo de entrada de masa y el rodillo inferior lo suficiente para que la masa pueda pasar al rodillo inferior directamente, sin ayuda, en el momento de in itia tion de la fabrication y asl evitar que esta caiga entre ambos rodillos. Esto provoca que los propios trabajadores sean los encargados de, manualmente, conducir el inicio de la masa entre el rodillo inferior y superior aproximando las manos a estos, suponiendo un grave problema de seguridad debido al riesgo de atrapamiento.Another problem that we find in the design of the food mills is at the time of starting the production. In the laminating process, the dough is introduced into the laminator through the input belt, to be subsequently placed on the lower roller, circulating between the lower and upper roller and leaving the laminator with a thickness less than the initial thickness. The problem lies in the mechanical impediment of being able to approach the dough input roller and the lower roller sufficiently so that the dough can pass to the lower roller directly, without help, at the time of initiation of the manufacture and thus avoid it falls between both rollers. This causes that the own workers are the ones in charge of, manually, to lead the beginning of the mass between the inferior roll and superior approaching the hands to these, supposing a serious problem of security due to the risk of entrapment.

EXPLICACION DE LA INVENCIONEXPLANATION OF THE INVENTION

Con el fin de evitar los inconvenientes mencionados en el apartado anterior, la invention propone, por una parte, un sistema que permite el movimiento del rodillo superior evitando sobre-esfuerzos y, por otro lado, la incorporation de un elemento mecanico, que permite la entrada de la masa en el laminador en el momento de in itia tion de la production sin necesidad de incorporarla de forma manual.In order to avoid the drawbacks mentioned in the previous section, the invention proposes, on the one hand, a system that allows the movement of the upper roller avoiding over-efforts and, on the other hand, the incorporation of a mechanical element, which allows the entrance of the mass in the laminator at the time of initiation of production without the need to incorporate it manually.

El sistema objeto de la invention, consta de dos mecanismos ubicados, cada uno, a un lado del laminador. Cada uno de ellos esta formado por dos patines y dos gulas, de forma que los patines deslizan a lo largo de las gulas que estan atornilladas a la bancada de la maquina. En estos patines va acoplado el soporte que sustenta el rodamiento sobre el que se apoya una gula y el eje del rodillo laminador, moviendose este de forma solidaria a los patines a lo largo de una corredera mecanizada en la bancada del laminador. Por seguridad, se anade a cada lado del soporte una cuna que se atornilla a este y encaja en su patln correspondiente de forma que, aunque alguno de los tornillos que unen el soporte con los patines se rompiera, no se podrla caer el rodillo superior. Unido al soporte de dicho rodillo se encuentra otra pieza mediante la cual se transmite el movimiento de regulation en altura desde el volante hasta el rodillo superior, para ello se introduce una varilla roscada que mediante su movimiento arrastrara el soporte del rodillo, uniendo todo este conjunto mediante la ayuda de dos rodamientos axiales de bolas sujetadas por una tuerca al final de la varilla, de forma que, al mover el volante, y con ello iniciar el movimiento de la varilla roscada a traves de una tuerca instalada en la parte superior de la bancada del laminador, el soporte comienza a moverse deslizando los patines a traves de las gulas, garantizando as! su movimiento totalmente lineal y uniforme a lo largo de la corredera.The system object of the invention consists of two mechanisms located, each one, on one side of the laminator. Each of them is formed by two skids and two gulas, so that the skids slide along the gulas that are screwed to the bed of the machine. In these skids is coupled the support that supports the bearing on which rests a glide and the axis of the roller rolling, moving it in a manner of solidarity to the skids along a slide mechanized in the bed of the laminator. For safety, a cradle is added to each side of the support that is screwed to it and fits into its corresponding shoe so that, even if some of the screws that join the support with the skids broke, the upper roller could not fall. Attached to the support of said roller is another piece through which the regulation movement in height is transmitted from the steering wheel to the upper roller, for this a threaded rod is introduced which by means of its movement will drag the roller support, joining all this assembly with the help of two axial ball bearings held by a nut at the end of the rod, so that, when moving the steering wheel, and thereby initiate the movement of the threaded rod through a nut installed on the top of the bench of the laminator, the support begins to move sliding the skids through the guides, thus guaranteeing! its movement totally linear and uniform along the slide.

Ademas, se acopla un engrasador, accesible desde el exterior de la maquina, que mediante un tubo plastico permite la lubrication de todos los elementos de transmision sin necesidad de retirar las protecciones de seguridad, evitando el desgaste y protegiendolo de la corrosion.In addition, a grease nipple, accessible from the outside of the machine, is connected by means of a plastic tube, allowing the lubrication of all the transmission elements without the need to remove the safety protections, avoiding wear and protecting it from corrosion.

En resumen, este sistema permite de forma comoda y segura, variar la position del rodillo superior accionando el volante que se encuentra en la parte superior de la maquina que hace que la varilla roscada transmita el movimiento al patln a traves de los ralles y de forma gradual y sin necesidad de esfuerzo el soporte se mueva tambien desplazando el rodillo al lugar adecuado.In summary, this system allows to comfortably and safely vary the position of the upper roller by actuating the steering wheel located on the upper part of the machine that causes the threaded rod to transmit the movement to the skate through the rails Gradually and without effort, the support moves also moving the roller to the right place.

Recordemos, que este mecanismo esta acoplado a cada lado de la maquina, de forma que se muevan ambos extremos del rodillo laminador superior. Remember, that this mechanism is coupled to each side of the machine, so that both ends of the upper rolling roller move.

La invencion tambien incluye la adicion de un elemento fabricado en plastico, apto para la empresa alimentaria, que llamaremos enhebrador, que comunicara la cinta de entrada con el rodillo laminador permitiendo la entrada de la masa automaticamente, sin necesidad de hacerlo manualmente por el operario, en el momento de iniciacion de la produccion. Esta pieza se colocara entre el rodillo de la cinta de entrada de masa y el rodillo inferior, apoyado en el bastidor de la maquina mediante dos esparragos a cada lado de esta, de forma que cuando la masa se introduzca en el laminador a traves de la cinta que circula por el rodillo de entrada sea dirigida por esta pieza al rodillo inferior. Asl, se evita que sea el propio trabajador el que tenga que dirigir la masa entre un rodillo y otro y, por consiguiente, el riesgo de atrapamiento, adaptandose mejor a la ley 31/1995, de 8 de noviembre, de Prevencion de Riesgos Laborales, que establece la necesidad de combatir los riesgos desde su origen.The invention also includes the addition of an element made of plastic, suitable for the food business, which we will call threader, which will communicate the entrance belt with the rolling mill allowing the entrance of the dough automatically, without having to do it manually by the operator, at the time of production initiation. This piece will be placed between the roll of the dough input belt and the lower roller, supported on the frame of the machine by two studs on each side of it, so that when the dough is introduced into the laminator through the The tape that circulates through the entrance roller is directed by this piece to the lower roller. Thus, it is avoided that the worker himself has to direct the mass between a roller and another and, therefore, the risk of entrapment, adapting better to the law 31/1995, of November 8, of Prevention of Occupational Risks , which establishes the need to combat risks from their origin.
