Descripción de una forma de realización preferidaDescription of a preferred embodiment

La invención será ahora entendida mejor con la siguiente descripción de una forma de realización preferida con la ayuda de los dibujos anexos incluyendo sustancialmente:The invention will now be better understood with the following description of a preferred embodiment with the help of the attached drawings including substantially:

- en Fig. 1 la vista en semisección radial axial de la bobinadora con sectores de mandril en receso y los sectores de la brida superior también en receso, girados hacia arriba;- in Fig. 1 the axial radial semi-section view of the winder with recessed mandrel sectors and sectors from the upper flange also in recess, turned upwards;

- en Fig. 2, una vista como en la Fig.1, pero donde tanto el mandril como los sectores de la brida superior son movidos a la posición de desenrollamiento, es decir, el mandril toma la forma cilíndrica y los sectores de la brida son dirigidos horizontalmente;- in Fig. 2, a view as in Fig. 1, but where both the mandrel and the upper flange sectors are moved to the unwind position, that is, the mandrel takes the cylindrical shape and the flange sectors are directed horizontally;

- en Fig. 3, una vista transversal del mandril a la altura de la palanca intermedia que mueve dichos sectores del mandril.- in Fig. 3, a cross-sectional view of the mandrel a the height of the intermediate lever that moves said sectors of the mandrel

Como representan las figuras descritas anteriormente, la invención se refiere sustancialmente a una bobinadora para cable y para barras de metal, del tipo mandril con un eje vertical que consiste en una brida de base (4) para el soporte de la base de la bobina y sectores de mandril (6) abisagrados en la base (41) que pueden ser movidos sobre la parte superior de una forma cilíndrica a una forma cónica colapsada y los sectores correspondientes de la brida superior (7) abisagrada en la parte superior (10) movible en concomitancia de dichos sectores de mandril, respectivamente desde una posición horizontal radial a una posición girada hacia arriba para permitir la extracción de la bobina y, viceversa donde, para el movimiento sincrónico de dichos sectores de mandril (6) y dichos sectores de brida (7) se usa un dispositivo coaxial (2) capaz de ser movido longitudinalmente a lo largo del eje del mandril, y consiste en:How the figures described represent above, the invention relates substantially to a cable and metal bar winder, mandrel type with a vertical axis consisting of a base flange (4) for the coil base support and mandrel sectors (6) hinges on the base (41) that can be moved on the part superior of a cylindrical shape to a collapsed conical shape and the corresponding sectors of the upper flange (7) hinged on the upper part (10) movable in concomitance of said sectors of mandrel, respectively from a radial horizontal position to a position turned up to allow removal of the coil and, vice versa where, for the synchronous movement of said mandrel sectors (6) and said flange sectors (7) a coaxial device (2) capable of being moved longitudinally to the mandrel shaft length, and consists of:

--
medios de palanca (61) abisagrados (21) que son abisagrados (62) en un asiento deslizante interno (60) de dichos sectores de mandril (6), ymedia lever (61) hinges (21) that are hinged (62) in a internal sliding seat (60) of said mandrel sectors (6), Y

--
medios de cremallera superiores (22) que engarzan con la correspondiente dentadura arqueada (71) coaxiales a dicha curva superior (10) y unidos a dichos sectores de brida (7);media top zippers (22) that link with the corresponding arched denture (71) coaxial to said upper curve (10) and attached to said flange sectors (7);

de modo que:so that:

--
cuando dicho dispositivo coaxial (2) es bajado: dichas palancas (61) son dirigidas hacia arriba y retiran dichos sectores de mandril (6), mientras que dicha cremallera (22) hace girar dichos sectores de brida (7) hacia arriba;when said coaxial device (2) is lowered: said levers (61) are directed upwards and remove said mandrel sectors (6), while said rack (22) rotates said sectors of flange (7) up;

--
cuando dicho dispositivo coaxial (2) es elevado: dichas palancas (61) son transportadas sustancialmente de forma radial y empujan dichos sectores de mandril (6) hacia afuera, mientras que dicha cremallera (22) hace girar dichos sectores de la brida (7) hacia abajo, es decir, sustancialmente de forma horizontal.when said coaxial device (2) is high: said levers (61) are transported substantially radially and push said mandrel sectors (6) outward, while said rack (22) rotates said sectors of the flange (7) downwards, it is that is, substantially horizontally.

Ventajosamente hay cuatro sectores mencionados, pero para diámetros pequeños podría haber incluso más de cuatro y para diámetros mayores incluso tres.Advantageously there are four sectors mentioned, but for small diameters there could be even more than four and for larger diameters even three.

Según la invención dichos sectores de la brida (7) tienen un diente (72), que, después de bajarlo, inserta la parte superior de dichos sectores de mandril (6) para prevenir su expansión adicional por la fuerza centrífuga durante la rotación del mandril. De esta manera se evita el peligro de accidentes por las grandes masas centrífugas, que giran a alta velocidad, ofreciendo una mayor seguridad operativa.According to the invention said flange sectors (7) have a tooth (72), which, after lowering it, inserts the upper part of said mandrel sectors (6) to prevent their additional expansion by centrifugal force during rotation of the mandrel. This avoids the danger of accidents due to the large centrifugal masses, which rotate at high speed, offering greater operational security.

En dicha brida de base (4) hay dientes intercambiables (42) para enganchar la cabeza de la barra o del cable para la formación de la primera bobina, mediante su sujeción entre dichos dientes (42) y la base del mandril (6).In said base flange (4) there are teeth interchangeable (42) to engage the head of the bar or the cable for the formation of the first coil, by means of its clamping between said teeth (42) and the base of the mandrel (6).

De esta manera el sistema constructivo de la brida de base es simplificada y es posible el enrollamiento de diferentes tipos de cable o barra, intercambiando dichos dientes.In this way the construction system of the base flange is simplified and the winding of different types of cable or bar, exchanging said teeth.

Se observará que dichos sectores del mandril (6) y dichos sectores de la brida (7) son abisagrados (10, 41) a un cuerpo giratorio central de la bobinadora (1, 4). De esta manera la estructura es particularmente robusta y funcional. Dicho cuerpo giratorio central de la bobinadora consiste en un centro anular (1) y una brida soporte de base (4) atornillada a este. De esta manera las piezas que forman la bobinadora son completamente desmontables e intercambiables.It will be noted that said sectors of the mandrel (6) and said sectors of the flange (7) are hinged (10, 41) to a central rotating body of the winder (1, 4). In this way the Structure is particularly robust and functional. Said body Rotary center of the winder consists of an annular center (1) and a base support flange (4) bolted to it. In this way the parts that form the winder are completely removable and  interchangeable

En las figuras no se muestran el soporte ni los sistemas de rotación de la bobinadora, siendo estos fácilmente deducibles por los expertos en la técnica, y formando esto parte del estado de la técnica. De la misma manera, los medios de movimiento axial de los sectores de movimiento de control (1) no son mostrados, estando esto también en el dominio de los expertos en la técnica, como por ejemplo, cilindros dinámicos fluidos colocados bajo dicho cuerpo de soporte de carga (1, 4).The figures do not show the support or the winding rotation systems, these being easily Deductibles by those skilled in the art, and forming this part of the state of the art. In the same way, the means of axial movement of the control movement sectors (1) no are shown, this being also in the domain of experts in the technique, such as fluid dynamic cylinders placed under said load bearing body (1, 4).

La conexión entre dicha palanca (61) y el sector del mandril respectivo (6) tiene lugar con la presencia de un abisagrado con un agujero ranurado (60). De esta manera existe la ventaja de evitar conexiones rígidas que de lo contrario necesitarían una articulación mayor; por esta razón dicho agujero ranurado es inclinado hacia arriba, otorgando una holgura adecuada.The connection between said lever (61) and the sector of the respective mandrel (6) takes place with the presence of a hinged with a slotted hole (60). In this way there is the advantage of avoiding rigid connections that otherwise they would need a bigger joint; for this reason said hole grooved is tilted up, giving a slack adequate.
