Description

Dispositivo para el reajuste de un carril de aguja respecto a un contracarril.Device for readjustment of a rail needle with respect to a counter rail.

La presente invención hace referencia a un dispositivo de reajuste de un carril de aguja hacia un contracarril fijo sobre una placa de apoyo como placa nervada, comprendiendo una silla de deslizamiento que se extiende desde la placa de apoyo dispuesta sobre un soporte como traviesa o calzada firme, así como al menos un elemento de rodamiento que se extiende desde un soporte de fijación, que sirve de apoyo para el carril de aguja.The present invention refers to a readjustment device of a needle rail towards a counter rail fixed on a support plate as a ribbed plate, comprising a sliding chair that extends from the support plate arranged on a support as a naughty or firm road, as well as at least one bearing element that extends from a support fixing, which serves as support for the needle rail.

Un dispositivo apropiado puede extraerse de la EP-A-0 964 100. Para poder emplear universalmente un dispositivo de rodamiento apropiado integrando un elemento de rodamiento y un soporte de fijación, se prevé que el elemento de rodamiento se configure regulable tanto en altura como también en su distancia al contracarril.An appropriate device can be removed from the EP-A-0 964 100. To be able to use universally an appropriate bearing device integrating a bearing element and a fixing bracket, it is expected that the bearing element is configured adjustable both in height and also in its distance to the rail.

Gracias a la EP-B-0 904 457 se conoce un dispositivo de reajuste de agujas, que se apoya sobre un plano de rodamiento, producido por un par de rodillos, de una silla de deslizamiento, estando el rodillo delantero del par de rodillos menos ajustado que el rodillo posterior y al menos un rodillo se dispone sobre una excéntrica como un eje de rodamiento configurado excéntricamente. De este modo debería producirse la posibilidad de ajustar la altura del elemento de rodamiento. El propio par de rodillos se configura asimismo regulable respecto al contracarril. El par de rodillos sale para ello de un soporte de fijación apropiado.Thanks to the EP-B-0 904 457 a known needle resetting device, which rests on a plane of bearing, produced by a pair of rollers, of a chair sliding, the front roller of the roller pair being less tight than the rear roller and at least one roller is disposed on an eccentric as a configured bearing shaft eccentrically. This should give rise to the possibility of adjust the height of the bearing element. The pair itself rollers are also adjustable with respect to the counter rail. The pair of rollers comes out of a fixing bracket. appropriate.

El dispositivo de rodamiento conocido está unido a la placa nervada, de forma que tenga lugar un desplazamiento conjunto. De este modo pueden producirse impactos sobre el carril de aguja, particularmente cuando se inserten ejes levadizos en el contracarril y, por tanto, también en la placa nervada.The known bearing device is attached to the ribbed plate, so that a displacement takes place set. In this way impacts can occur on the rail of needle, particularly when draw axes are inserted into the counter rail and, therefore, also in the ribbed plate.

La presente invención se basa en el problema de configurar un dispositivo del tipo citado inicialmente, de forma que se lleve a cabo una asignación evidente del elemento de rodamiento al contracarril y se garantice, sin embargo, al mismo tiempo que sobre el carril de aguja no pueda aplicarse ninguna fuerza que produzca impactos incontrolados.The present invention is based on the problem of set up a device of the type cited initially, so that an obvious assignment of the bearing element is carried out to the counter lane and be guaranteed, however, at the same time as no force can be applied to the needle rail that produce uncontrolled impacts.

Conforme a la presente invención, el problema se resuelve esencialmente por el hecho de que el soporte de fijación está unido de manera desmontable con un inserto en la placa de apoyo y que, por su parte, el inserto esté unido por el borde con la placa de apoyo a través de una capa intermedia elástica.In accordance with the present invention, the problem is resolves essentially by the fact that the fixing bracket it is detachably attached with an insert in the support plate and that, meanwhile, the insert is joined by the edge with the plate of support through an elastic intermediate layer.

Conforme a la presente invención, el soporte de fijación sale de un inserto, unido por su parte elásticamente con la placa de apoyo como placa nervada. De este modo se lleva a cabo casi un desacoplamiento, de forma que, al introducir, por ejemplo, los ejes levadizos en la placa de apoyo, éste no se transmita al inserto y, por tanto, al soporte de fijación para el, al menos uno, elemento de rodamiento. Al mismo tiempo, para el inserto no son necesarios medios especiales de fijación, ya que tiene lugar una fijación junto con la placa de apoyo.In accordance with the present invention, the support of fixation comes out of an insert, joined by its part elastically with the Support plate as ribbed plate. In this way it is carried out almost a decoupling, so that, by introducing, for example, the lifting axes on the support plate, this is not transmitted to the insert and, therefore, to the fixing bracket for the at least one element of bearing. At the same time, they are not necessary for the insert special fixing means, since fixing takes place together With the support plate.

Se prevé, particularmente, que el elemento de rodamiento atraviese la silla de deslizamiento, de forma que se obtenga una unidad compacta; porque, conforme a la EP-B-0 904 457, el soporte de fijación para el elemento de rodamiento se dispone junto a la silla de deslizamiento, de forma que sean necesarios medios adicionales de fijación. Además, la placa nervada tiene que configurarse más amplia de lo habitual.It is envisaged, in particular, that the element of bearing goes through the sliding chair, so that get a compact unit; because, according to the EP-B-0 904 457, the support of fixing for the bearing element is arranged next to the chair of sliding, so that additional means of fixation. In addition, the ribbed plate has to be configured wider usual.

En un perfeccionamiento de la presente invención se prevé, que el inserto se pretense de tal manera en la dirección del soporte, que el inserto descanse sobre el soporte, independientemente de la posición vertical de la placa de apoyo. Esto puede realizarse de forma que el inserto sea atravesado por un elemento de fijación como perno roscado, a través del cual se une el inserto con el soporte como traviesa o calzada firme. De este modo se lleva a cabo, al mismo tiempo, una fijación de la placa de apoyo como placa nervada, ya que el inserto está unido con la placa de apoyo a través de la capa intermedia elástica. Particularmente se lleva a cabo una unión por vulcanizado entre el inserto y la placa de apoyo.In an improvement of the present invention it is envisaged that the insert will be prestressed in this way in the direction of the support, that the insert rests on the support, regardless of the vertical position of the support plate. This can be done so that the insert is pierced by a fixing element as a threaded bolt, through which the insert with the support as a naughty or firm road. In this way a fixing of the support plate is carried out at the same time as a ribbed plate, since the insert is attached to the plate support through the elastic intermediate layer. Particularly performs a vulcanized joint between the insert and the plate support.

Alternativamente, existe también la posibilidad de fijar el inserto a través de la placa de apoyo al soporte, de forma que el inserto descanse siempre superficialmente sobre el soporte, sin que el propio inserto sea atravesado por un elemento de fijación como perno roscado. El inserto puede vulcanizarse para ello en la placa de apoyo, de forma que, en estado no incorporado, la superficie del fondo del inserto sobresalga de la superficie de base de la placa de apoyo. Si entonces se fija la unidad placa de apoyo/inserto sobre el soporte como traviesa o calzada firme, el inserto experimenta una aplicación continua de fuerza en la dirección del soporte con la consecuencia de que, también cuando un eje levadizo actúe sobre la placa de apoyo de forma que la placa de apoyo se ajuste verticalmente, el inserto superficial se apoye sobre el soporte.Alternatively, there is also the possibility to fix the insert through the support plate to the support, of so that the insert always rests superficially on the support, without the insert itself being pierced by an element of fixing as threaded bolt. The insert can be vulcanized for it on the support plate, so that, in an unincorporated state, the bottom surface of the insert protrudes from the base surface of the support plate. If the unit plate is then fixed support / insert on the support as a naughty or firm road, the insert experiences a continuous application of force in the direction of the support with the consequence that, also when a draw shaft act on the support plate so that the plate support fit vertically, the surface insert rests on the support.

El inserto debería tener además una ranura que discurra en la dirección longitudinal de la placa de apoyo y dentro de la cual se extienda sectorial y rotatoriamente el, al menos uno, elemento de rodamiento. Se prevé particularmente que la longitud de la ranura se diseñe de forma que se dispongan de al menos dos elementos de rodamiento en serie en la dirección longitudinal de la placa de apoyo. Los ejes de los elementos de rodamiento discurren además habitualmente paralelos o aprox. paralelos al eje longitudinal del carril de apoyo y/o de aguja.The insert should also have a slot that run in the longitudinal direction of the support plate and inside from which the at least one sectorially and rotationally extends bearing element. It is particularly expected that the length of the slot is designed so that at least two are available series bearing elements in the longitudinal direction of the Support plaque. The axes of the bearing elements run also usually parallel or approx. parallel to the axis Longitudinal support rail and / or needle.

A lo largo de la ranura, es decir, de sus bordes longitudinales, se prevén incorporaciones de fijación para poder ajustar el soporte de fijación en la dirección longitudinal de la placa de apoyo. De este modo se garantiza que la distancia respecto al contracarril pueda ajustarse en la medida deseada, para garantizar un soporte óptimo del carril de aguja.Along the groove, that is, its edges lengthwise, fixing incorporations are planned to be able to adjust the fixing bracket in the longitudinal direction of the Support plaque. This ensures that the distance from the counter rail can be adjusted to the desired extent, to ensure optimal needle rail support.

Para proporcionar un dispositivo compacto se propone, además, que la silla de deslizamiento tenga una sección, que rodee al menos sectorialmente el inserto. La silla de deslizamiento presenta para ello particularmente una geometría en U, discurriendo los brazos laterales de la silla de deslizamiento a lo largo de los bordes longitudinales del inserto y, particularmente, fuera de estos. El propio brazo transversal se extiende directamente a lo largo del contracarril.To provide a compact device it also proposes that the sliding chair has a section, that surrounds at least the sector insert. The chair of sliding presents, in particular, a U geometry, running the side arms of the sliding chair at along the longitudinal edges of the insert and, particularly, out of these. The cross arm itself extends directly along the counter rail.

Un primer modo de ejecución, representado en las Fig. 1-3, de un dispositivo para el ajuste de un carril de aguja 11 respecto a un contracarril 10 comprende, de manera conocida, una placa nervada 12 dispuesta, por ejemplo, sobre una traviesa o una calzada firme, así como una silla de deslizamiento 14 que soporta el carril de aguja 11, dispuesta de manera desmontable sobre la placa nervada 12 a través de elementos elásticos de varilla 16, 18. Puede darse además una estructura, como la que puede extraerse de la WO-A-94/05858, a cuya revelación se hace referencia expresa. La silla de deslizamiento 14 sirve además, al mismo tiempo, para la fijación del contracarril 10 y descansa, en este contexto, sobre una sección 20 del pie 22 del contracarril 10. La sección 24, situada lejos de la silla de deslizamiento, del pie 22 del contracarril 10 se bloquea de manera habitual a través de, por ejemplo, resortes tensores 28 que pueden fijarse por medio de un tornillo tensor 26. A este respecto se hace referencia a estructuras suficientemente conocidas y/o alternativas.A first mode of execution, represented in the Fig. 1-3, of a device for adjusting a needle rail 11 with respect to a counter rail 10 comprises, of known way, a ribbed plate 12 arranged, for example, on a naughty or firm road, as well as a chair sliding 14 that supports the needle rail 11, disposed of detachable way on the ribbed plate 12 through elements rod elastics 16, 18. A structure may also occur, such as which can be extracted from the WO-A-94/05858, whose disclosure is It makes express reference. The sliding chair 14 also serves, at the same time, for fixing the counter rail 10 and rests, in this context, on a section 20 of foot 22 of counter rail 10. Section 24, located away from the sliding chair, from the foot 22 of the counter-rail 10 is blocked in the usual way through, for example, tension springs 28 that can be fixed by means of a tension screw 26. In this regard, reference is made to structures sufficiently known and / or alternatives.

La silla de deslizamiento 14 presenta una geometría en U, discurriendo el brazo transversal 30 directamente a lo largo del contracarril 10 y descansando por debajo sobre la sección 20 del pie del carril 22. Los brazos laterales 32, 34 de la silla de deslizamiento 14, que discurren a lo largo de dirección longitudinal de la placa nervada 12, o sea, transversalmente a los carriles 10, 11, rodean un inserto 36 de la placa nervada 12, unido, por su parte, con la placa nervada 12 a través de una capa intermedia elástica 38. Una unión del inserto 36 con la placa nervada 12 se lleva a cabo particularmente por vulcanizado.The sliding chair 14 has a U geometry, running the transverse arm 30 directly to along the rail 10 and resting below on the section 20 of the foot of rail 22. The side arms 32, 34 of the sliding chair 14, which run along direction longitudinal of the ribbed plate 12, that is, transversely to the lanes 10, 11, surround an insert 36 of the ribbed plate 12, attached, on the other hand, with the ribbed plate 12 through a layer elastic intermediate 38. A union of the insert 36 with the plate veined 12 is carried out particularly by vulcanizing.

El inserto 36 presenta una ranura longitudinal 42, cuyo ancho se selecciona de forma que pueda extenderse dentro de estos rodillos 44, 46, que parten de un soporte de fijación 48 unido con el inserto 36. Para ello, el inserto se presenta, a lo largo de la ranura 42, y cuyas ambas caras muestran incorporaciones 50, 52, como perforaciones en las que puede fijarse el soporte de fijación 48 por medio de tornillos 54, 56. Los tornillos 54, 56 se abren paso además a través de los orificios alargados 58, 60 existentes en el soporte de fijación 48, de forma que pueda efectuarse un ajuste continuo del soporte de fijación 48 y, por tanto, de los elementos de rodamiento 44, 46 respecto al contracarril 10; porque los orificios alargados 58, 60 se diseñan en base a la distancia de las aberturas y/o perforaciones 50, 52 en el inserto 36, de forma que se posibilite una variación continua de la distancia respecto al contracarril 10.The insert 36 has a longitudinal groove 42, whose width is selected so that it can extend within these rollers 44, 46, which start from a attached fixing bracket 48 with insert 36. To do this, the insert is presented, along slot 42, and whose both faces show incorporations 50, 52, as holes in which the fixing bracket can be fixed 48 by means of screws 54, 56. Screws 54, 56 make their way also through the elongated holes 58, 60 existing in the fixing bracket 48, so that an adjustment can be made continuous of the fixing bracket 48 and, therefore, of the elements bearing 44, 46 with respect to counter rail 10; because the elongated holes 58, 60 are designed based on the distance of the openings and / or perforations 50, 52 in the insert 36, so that enable a continuous variation of the distance from the counter rail 10.

Gracias a que el inserto 36 está unido con la placa nervada 12 a través de la capa intermedia elástica 38, se lleva a cabo casi un desacoplamiento, con el que se garantiza que el inserto 36 descanse constantemente sobre el soporte como traviesa o calzada firme y, por tanto, el soporte de fijación 48 para los elementos de rodamiento 44, 46 ocupe una posición evidente. Por consiguiente, no se lleva a cabo un desplazamiento conjunto con la placa nervada 12.Thanks to the insert 36 being connected with the ribbed plate 12 through elastic intermediate layer 38, is carries out almost a decoupling, with which it is guaranteed that the insert 36 rest constantly on the support as naughty or firm driveway and therefore the fixing bracket 48 for the bearing elements 44, 46 occupy an obvious position. By consequently, a joint displacement with the ribbed plate 12.

El perno roscado 40, 62, a través del cual se lleva a cabo una unión con el soporte se lleva a cabo, atraviesa la placa nervada 12 en las zonas límite transversales de ésta.The threaded bolt 40, 62, through which carries out a union with the support is carried out, crosses the ribbed plate 12 in the transverse boundary zones of the latter.

Los pernos roscados 40, 62 atraviesan además insertos de plástico 64, 66, dispuestos en orificios alargados, para posibilitar un ajuste de la placa nervada 12 a lo largo de su eje longitudinal, en función de la geometría y/o evolución de la abertura para los pernos roscados 40, 62 del respectivo inserto 64, 66. Sin embargo, a este respecto se hace asimismo referencia a estructuras suficientemente conocidas, como las conocidas, por ejemplo, gracias a la DE-A-44 06 105.Threaded bolts 40, 62 also pass through plastic inserts 64, 66, arranged in elongated holes, for enable adjustment of the ribbed plate 12 along its axis longitudinal, depending on the geometry and / or evolution of the opening for threaded bolts 40, 62 of the respective insert 64, 66. In this regard, however, reference is also made to sufficiently known structures, such as those known, by example, thanks to DE-A-44 06 105.

De las Fig. 4 y 5 puede extraerse otro modo de ejecución de un dispositivo de reajuste deslizante de un carril de aguja respecto a un contracarril. Además, conforme a las Fig. 1 y 3, para los mismos elementos se emplean los mismos símbolos de referencia.From Fig. 4 and 5, another mode of execution of a slide reset device of a rail needle with respect to a counter rail. In addition, according to Figs. 1 and 3, for the same elements the same symbols of reference.

El ejemplo de ejecución de las Fig. 4 y 5, se distingue del de las Fig. 1 a 3 en que el tornillo 40, que co-bloquea la placa nervada 12, no discurre a distancia del inserto 32, sino que discurre con el inserto 64 dentro del inserto 36 que aloja el soporte de fijación 48. De este modo existe la posibilidad de que se aplique una tensión previa al inserto 36 a través del tornillo 40. Ésta da lugar a que la posición intermedia 36 descanse constantemente sobre el soporte, es decir, independientemente de si la placa nervada 12 experimenta una fuerza desde el soporte, por ejemplo, al introducir un eje levadizo. La placa nervada 12 se inmoviliza igualmente a través del tornillo 40, ya que el inserto 36 está unido con la placa nervada 12 a través de la capa intermedia 38.The exemplary embodiment of Figs. 4 and 5, is distinguishes from that of Figs. 1 to 3 in that the screw 40, which co-blocks the ribbed plate 12, does not run to distance of the insert 32, but it runs with the insert 64 inside of the insert 36 housing the fixing bracket 48. In this way there is a possibility that a pre-tension is applied to the insert 36 through screw 40. This results in the position intermediate 36 rest constantly on the support, that is, regardless of whether the ribbed plate 12 experiences a force from the support, for example, when introducing a lifting shaft. The ribbed plate 12 is also immobilized through screw 40, since the insert 36 is connected with the ribbed plate 12 through intermediate layer 38.
