Abstract

The machine has a large bench on which a trolley for moving a probe holder is arranged. Closed test tubes with corks are arranged on the probe holder. A tilting comb structure of arms are arranged between the tubes, such that the tilting motion of the comb structure of arms loosens the corks and makes the corks drop towards a collecting tray. A tilted barrier allows the passage of the probe holder towards the comb structure to isolate the uncorked test tubes towards the loading and unloading zone of the probe holder. A protective cover is manually driven to tilt and cover the open portion of the machine. The probe holder can be removed for cleaning and maintenance.

Object of the invention

La presente invención se refiere a unos perfeccionamientos introducidos en la máquina destaponadora de tubos de análisis clínicos, que se describe y reivindica en la Patente de Invención P200402506, mejoras orientadas a optimizar el funcionamiento de la máquina.The present invention relates to some improvements introduced in the uncovering machine of clinical analysis tubes, described and claimed in the Invention Patent P200402506, improvements aimed at optimizing the machine operation

De forma mas concreta los perfeccionamientos de la invención afectan al sistema de transmisión entre el motor de desplazamiento del carro y el propio carro, al objeto de conseguir un perfecto control y sincronismo de movimientos.More specifically the improvements of the invention affect the transmission system between the engine of displacement of the car and the car itself, in order to achieve perfect control and synchronism of movements.

Background of the invention

En la Patente de Invención P200402506 se describe una máquina destaponadora de tubos para análisis clínicos y similares, en la que sobre una bancada se establece un carro portador de la gradilla con los tubos de ensayo, cerrados con sus correspondientes tapones, a la vez que también sobre dicha bancada se establece un peine basculante, cuyos brazos son capaces de pasar entre las alineaciones de tubos y de bascular para provocar el desprendimiento de los tabones y su caída hacia una bandeja colectora.In the Invention Patent P200402506, describes a tube uncovering machine for clinical analysis and the like, in which on a bench a car is established rack carrier with test tubes, closed with their corresponding plugs, while also on said bench a swinging comb is established, whose arms are able to pass between tube and swing alignments to cause detachment of the boards and their fall towards a tray collector

Para el citado desplazamiento del carro porta-gradillas, se utiliza un moto-reductor, convenientemente fijado a la bancada de la máquina, que actúa sobre una polea arrastradora de una cinta transportadora, de trayectoria horizontal, establecida entre dicha polea motriz y una polea de retomo, siendo solidario a dicha correa el carro porta-gradillas, desplazable longitudinal y alternativamente a lo largo de la bancada, en primer lugar para trasladar los tubos de ensayo cerrados a la zona de destaponado de la máquina, y posteriormente para retornar a su posición primitiva.For the said car displacement rack holder, a moto-reducer, conveniently fixed to the bench of the machine, which acts on a belt pulley conveyor, horizontal path, established between said drive pulley and a return pulley, being integral with said belt the rack carriage, longitudinally movable and alternatively along the bench, first to move the closed test tubes to the uncapped area of the machine, and later to return to its position primitive

Pues bien, este sistema de transmisión, a través de las poleas y la correa citadas, presenta en la práctica problemas de índole funcional derivados de la propia naturaleza de la cinta transportadora, que debe ser de naturaleza elástica, lo que hace que se produzcan deformaciones indeseadas en la misma, que repercuten negativamente en un correcto sincronismo entre los elementos móviles de la máquina.Well, this transmission system, through of the pulleys and the belt mentioned, presents in practice functional problems arising from the nature of the conveyor belt, which must be elastic in nature, which causes unwanted deformations in it, which negatively impact on a correct synchronism between moving elements of the machine.

Description of the invention

Los perfeccionamientos que la invención propone están orientados precisamente a resolver la problemática que acaba de exponerse, asegurándose un perfecto control en el desplazamiento del carro y un también perfecto sincronismo entre los diferentes elementos móviles de la máquina.The improvements proposed by the invention They are aimed precisely at solving the problem that ends of exposing oneself, ensuring perfect control in displacement of the car and also a perfect synchronism between the different moving elements of the machine.

Para ello y de forma más concreta los perfeccionamientos que se preconizan consisten en sustituir la citada cinta transportadora, con sus correspondientes poleas, por un husillo, montado con libertad de giro entre soportes extremos que lo inmovilizan axialmente, husillo que recibe el movimiento directa o indirectamente del correspondiente moto-reductor, y sobre el que está montado un patín roscado que actúa como tuerca debidamente solidarizado al carro, de manera que el movimiento del motor en uno u otro sentido, provoca el giro a su vez en uno u otro sentido del husillo y, en consecuencia, el desplazamiento longitudinal sobre el mismo del carro, también en uno u otro sentido.To do this and more specifically the improvements that are recommended are to replace the said conveyor belt, with its corresponding pulleys, by a spindle, mounted with freedom of rotation between end brackets that immobilize it axially, spindle that receives the movement directly or indirectly of the corresponding motor-reducer, and on which a skate is mounted threaded that acts as a nut duly in solidarity with the car, of so that the movement of the motor in one way or another causes the turn in one direction or another of the spindle and, in consequently, the longitudinal displacement thereon of the car, also in one way or another.

Este tipo de transmisión ralentiza ligeramente el funcionamiento de la máquina, ya que el desplazamiento del patín a lo largo del husillo es mas lento que el desplazamiento de la anterior correa, pero sin embargo ofrece unas óptimas prestaciones como el elemento de transmisión motriz que constituye, permitiendo y asegurando un perfecto sincronismo entre el movimiento del carro porta-gradillas y el resto de los elementos móviles de la máquina.This type of transmission slows down slightly the operation of the machine, since the displacement of the skate along the spindle it is slower than the displacement of the previous strap, but nevertheless offers optimum performance as the power transmission element that constitutes, allowing and ensuring a perfect synchronism between the movement of the car rack holder and the rest of the mobile elements of the machine
