El objeto de la invención es conseguir una gradilla capaz de cumplimentar su función básica como tal elemento portador de tubos de análisis clínicos, con la de elementos de fijación para dichos tubos, que los mantenga sólidamente inmovilizados durante la maniobra de extracción automática de los complementarios y correspondientes tapones, al traccionar en sentido ascendente sobre estos últimos, y todo ello sin el menor riesgo de daño para dichos tubos.The object of the invention is to achieve a rack capable of completing its basic function as such element carrier of clinical analysis tubes, with elements of fixation for said tubes, to keep them solidly immobilized during the automatic extraction maneuver of complementary and corresponding plugs, when pulling on ascending sense about the latter, and all without the least risk of damage to such tubes.

Antecedentes de la invenciónBackground of the invention

El propio solicitante es titular de la patente de invención española con número de solicitud P - - - -, en la que se describe una máquina destaponadora de tubos para análisis clínicos y similares, capaz de destaponar de forma automática y en una maniobra única, todos los tubos alojados en una determinada gradilla.The applicant himself owns the patent of Spanish invention with application number P - - - -, in which a machine is described tube uncorking machine for clinical and similar analysis, capable of uncover automatically and in a single maneuver, all tubes housed in a certain rack.

Dicha máquina se basa en disponer la gradilla con los tubos cerrados sobre un carro, desplazar seguidamente dicho carro hacia un peine provisto de brazos o dedos capaces de penetrar entre alineaciones adyacentes de tubos de la gradilla y de bascular seguidamente en sentido ascendente, de manera que en dicho movimiento los brazos arrastren los tapones que cierran los tubos, maniobra en la que dichos tubos deben quedar inmovilizados a la gradilla, y ésta a su vez inmovilizada al carro, para que en el movimiento ascendente del peine, tan sólo resulten arrastrados los tapones, y no los tubos correspondientes, para que pueda producirse el destaponado, sin que en dicha patente se refleje una solución concreta para dicha inmovilización de los tubos.This machine is based on arranging the rack with the tubes closed on a car, then move said carriage to a comb with arms or fingers capable of penetrating between adjacent alignments of rack and tilt tubes then upwards, so that in said movement the arms drag the plugs that close the tubes, maneuver in which said tubes must be immobilized to the rack, and this in turn immobilized to the car, so that in the upward movement of the comb, just drag the plugs, and not the corresponding tubes, so that it can be produced the uncapped one, without a solution in said patent concrete for said immobilization of the tubes.

Descripción de la invenciónDescription of the invention

La gradilla que la invención propone ha sido concebida como un complemento para la máquina destaponadora de la patente de invención anteriormente citada, a cuyo efecto está dotada de medios que permiten tanto la libre introducción y extracción de los tubos como el bloqueo de los mismos durante la maniobra de destaponado.The rack proposed by the invention has been conceived as a complement to the uncovering machine of the invention patent cited above, for which purpose it is equipped with means that allow both free introduction and extraction of the tubes as blocking them during the uncapping maneuver.

Para ello y de forma más concreta, en dicha gradilla participan dos placas iguales y superpuestas, de las que la superior está dotada de una pluralidad de orificios distribuidos reticularmente y de diámetro acorde al de los tubos a recibir, estando ambas placas relacionadas entre sí mediante distanciadores que las convierten en un conjunto monopieza, distanciadores que actúan además como guías de desplazamiento longitudinal para otras dos placas interiores, deslizantes, provista cada una de ellas de una pluralidad de semicasquillos dotados en su cara cóncava de un revestimiento elastomérico, formal y dimensionalmente acordes con el diámetro de los tubos que han de acoplarse en la gradilla, de manera que cada pareja de semicasquillos correspondientes a las dos placas deslizantes, correspondientes a su vez a un determinado tubo, actúan como una abrazadera sobre este último, que tiende a mantenerse abierta por un acoplamiento elástico entre ambas placas deslizantes, para facilitar la introducción de los tubos en el interior de la gradilla, y que se cierra durante la maniobra de destaponado de los tubos por efecto de una presión ejercida sobre los bordes de las dos placas deslizantes, concretamente sobre una de ellas a través del propio carro y por la otra por un tope contrapuesto establecido en la bancada de la máquina, a cuyo efecto las citadas placas deslizantes están provistas de orificios rasgados para paso de los citados distanciadores, que permiten dicho desplazamiento longitudinal de las placas deslizantes.To do this and more specifically, in said two equal and overlapping plates participate, of which the upper one is provided with a plurality of distributed holes reticularly and of diameter according to that of the tubes to receive, both plates being interconnected by spacers that make them a single piece set, spacers that they also act as guides for longitudinal displacement for others two inner plates, sliding, each provided with a plurality of half-shells endowed on its concave face with a elastomeric coating, formally and dimensionally consistent with the diameter of the tubes to be coupled in the rack, of so that each pair of half-shells corresponding to the two sliding plates, corresponding in turn to a certain tube, act as a clamp on the latter, which tends to stay open by an elastic coupling between both plates sliders, to facilitate the introduction of the tubes in the inside the rack, and that closes during the maneuver of uncapping of the tubes due to the pressure exerted on the edges of the two sliding plates, specifically on a of them through the car itself and on the other by a stop counterpoint established on the machine bed, for which purpose the aforementioned sliding plates are provided with torn holes for passage of said spacers, which allow said longitudinal displacement of the sliding plates.

Se consigue de esta manera no sólo una correcta fijación de los tubos, sino que además ésta se produzca precisamente en el momento en el que la gradilla se sitúa sobre la zona de trabajo del peine, donde va a producirse el destaponado.You get this way not only a correct one fixing of the tubes, but also that this occurs precisely at the moment when the rack is placed on the working area of the comb, where the uncovered

Descripción de los dibujosDescription of the drawings

Para complementar la descripción que se está realizando y con objeto de ayudar a una mejor comprensión de las características del invento, de acuerdo con un ejemplo preferente de realización práctica del mismo, se acompaña como parte integrante de dicha descripción, un juego de dibujos en donde con carácter ilustrativo y no limitativo, se ha representado lo siguiente:To complement the description that is being performing and in order to help a better understanding of the characteristics of the invention, according to a preferred example of practical realization of it, is accompanied as part member of that description, a set of drawings where with illustrative and non-limiting nature, what has been represented next:

La figura 1.- Muestra una representación esquemática en alzado lateral y en sección de una gradilla de análisis clínicos y similares realizada de acuerdo con el objeto de la presente invención, la cual aparece montada sobre el carro de la máquina destaponadora y en situación de desbloqueo para los tubos.Figure 1.- Shows a representation schematic in side elevation and in section of a rack of clinical and similar analyzes performed in accordance with the purpose of the present invention, which appears mounted on the carriage of the uncovering machine and unlocking for tubes

La figura 2.- Muestra una representación similar a la de la figura anterior, en la que la gradilla se ha desplazado hacia el peine destaponador y los tubos aparecen bloqueados en el seno de la misma.Figure 2.- Shows a similar representation to that of the previous figure, in which the rack has moved towards the uncapping comb and the tubes appear blocked in the bosom of it.

Realización preferente de la invenciónPreferred Embodiment of the Invention

En las figuras reseñadas y por mera simplificación del dibujo, se ha representado una gradilla (1) con tan sólo dos alineaciones de tubos (2), realización que no se ajusta a la práctica donde cualquier gradilla dispondrá de un número considerablemente mayor de alineaciones de tubos (2), pero siendo su estructura repetitiva, por lo que no es precisa la representación de todas ellas que, como acaba de decirse, tan sólo complicaría el dibujo.In the figures outlined and by mere simplification of the drawing, a rack (1) with only two tube alignments (2), an embodiment that is not fits into practice where any rack will have a considerably larger number of tube alignments (2), but being its repetitive structure, so the representation of all of them that, as just said, just It would complicate the drawing.

Pues bien, de acuerdo con la invención dicha gradilla (1) está constituida mediante una placa inferior o placa base (3) y una placa superior (4), relacionada con la primera mediante distanciadores (5), preferentemente situados en correspondencia con sus esquinas, siendo la placa superior (4) formal y dimensionalmente coincidente con la inferior (3), pero estando provista de orificios (6) distribuidos reticularmente, para paso de los tubos (2) con sus correspondientes tapones de cierre (7), hasta una situación límite en la que los tubos (2) apoyan sobre la placa inferior (3), de forma análoga a una gradilla convencional.Well, according to the invention said Rack (1) is constituted by a lower plate or plate base (3) and a top plate (4), related to the first by spacers (5), preferably located in correspondence with its corners, the top plate being (4) formally and dimensionally coincident with the lower one (3), but being provided with holes (6) reticularly distributed, for passage of the tubes (2) with their corresponding closure caps (7), up to a limit situation in which the tubes (2) support on the bottom plate (3), analogous to a rack conventional.

Entre las dos placas (3) y (4) citadas se establecen otras dos placas deslizantes (8) y (9), en cada una de las cuales se define, en correspondencia con cada tubo (2), un semicasquillo (10) y (11), con un revestimiento interior (12) de un material elastoméricos, para no dañar al tubo (2), y con una curvatura acorde con la de este último, de manera que los dos semicasquillos (10) y (11) correspondientes a cada tubo (2), son capaces de mantenerse separados, tal como muestra la figura 1, para permitir la libre introducción y extracción de los tubos (2), o bien de aproximarse, como si se tratase de una mordaza, para inmovilizar el tubo (2) a la gradilla (1), durante la fase de extracción de los tapones (7).Between the two plates (3) and (4) mentioned are establish two other sliding plates (8) and (9), in each of which is defined, in correspondence with each tube (2), a half cap (10) and (11), with an inner lining (12) of a elastomeric material, so as not to damage the tube (2), and with a curvature according to the latter, so that the two half-shells (10) and (11) corresponding to each tube (2), are able to stay apart, as shown in figure 1, to allow free introduction and removal of the tubes (2), or well to approach, as if it were a gag, to immobilize the tube (2) to the rack (1), during the phase of cap removal (7).

Los semicasquillos (10) y (11) tienden permanentemente a la situación de distanciamiento o apertura, merced a que las placas deslizantes (8) y (9) están relacionadas entre sí mediante un acoplamiento elástico (13), materializado por ejemplo en un cuerpo elastomérico fijado simultáneamente a ambas placas, y su aproximación o cierre se produce automáticamente en el momento inmediatamente anterior a la eliminación de los tapones (7) por parte del peine (14) de la máquina destaponadora, debido a que el carro (15) sobre el que se deposita la gradilla (1) y que es arrastrado hacia el peine (14) por una correa de arrastre (16) o similar, cuenta con un tope (17) que actúa sobre el borde de la placa deslizante (9) emergente de las placas (3) y (4) de la gradilla, mientras que el borde libre (19) de la otra placa deslizante (8) incide a su vez en situación límite de desplazamiento para el carro (15) sobre un tope complementario (20) de que está provista la máquina, lo que fuerza a un desplazamiento relativo entre ambas placas (8) y (9), con la consecuente estrangulación de sus semicasquillos (10) contra los tubos (2), que quedan así fijados a la gradilla (1), a la vez que esta última queda fijada al carro (15) de la máquina.The half-shells (10) and (11) tend permanently to the situation of distancing or opening, thanks to the sliding plates (8) and (9) being related each other by an elastic coupling (13), materialized by example in an elastomeric body fixed simultaneously to both plates, and their approach or closure occurs automatically in the moment immediately before the removal of the plugs (7) by the comb (14) of the uncovering machine, because the car (15) on which the rack (1) is deposited and which is dragged towards the comb (14) by a drag belt (16) or similar, it has a stop (17) that acts on the edge of the sliding plate (9) emerging from the plates (3) and (4) of the rack while the free edge (19) of the other plate Sliding (8) also affects the limit situation of displacement for the carriage (15) over a complementary stop (20) that the machine is provided, which forces a displacement relative between both plates (8) and (9), with the consequent strangulation of its half-shells (10) against the tubes (2), which are thus fixed to the rack (1), while the latter is fixed to the carriage (15) of the machine.

Se consigue de esta manera no sólo una correcta fijación de los tubos (2) mediante el destaponado de los mismos, sino que dicha fijación se produzca de forma automática en el momento en el que la gradilla alcanza la zona de trabajo del peine (14) de la máquina destaponadora.You get this way not only a correct one fixing the tubes (2) by uncovering them, but that said fixation occurs automatically in the moment in which the rack reaches the working area of the comb (14) of the uncovering machine.
