Description

Método de dosificación y máquina dosificadora de masas y pastas alimentarias correspondiente. Dosing method and corresponding mass measuring machine and pasta.
Esta invención se refiere a un método para la dosificación de masas y pastas alimentarias que presenta esencialmente las etapas de suministro, compactación, y dosificación de la masa, en las que el suministro se realiza por medio de una máquina rotativa de bombeo. Se refiere también esta invención a una máquina que emplea dicho procedimiento, y que presenta al menos un rotor de dosificación de la masa, provisto de unas paletas empujadoras de la masa hacia una embocadura de salida, en la que existen medios de corte de la dosis de masa requerida.This invention relates to a method for the dosing of doughs and pastes which essentially presents the stages of supply, compaction, and dosage of the dough, in which the supply is carried out by means of a rotary pumping machine. This invention also relates to a machine that employs said method, and which has at least one mass dosing rotor, provided with pusher vanes of the mass towards an outlet, in which there are means for cutting the dose. of required mass.
En el momento presente se están llevando a cabo métodos de dosificación en los que por medio de máquinas provistas de émbolos se lleva a cabo un suministro y compactación, pero en los que ambas operaciones se llevan a cabo por la retracción y avance de un émbolo sobre una cámara, de modo que durante su fase de retracción se produce una depresión, y al quedar libre el acceso de la masa a dicha cámara, ésta se llena de la masa situada en la zona de entrada, para por medio del empuje ser impulsada hacia una zona de dosificación. La dosificación es volumétrica.At the present time, dosing methods are being carried out in which, by means of machines equipped with pistons, a supply and compaction is carried out, but in which both operations are carried out by the retraction and advance of a piston on a chamber, so that during its retraction phase a depression occurs, and when the mass access to said chamber is free, it is filled with the mass located in the entrance area, so as to be pushed towards the chamber. A dosage zone. The dosage is volumetric.
Este método y máquina presenta esencialmente varios inconvenientes, a saber:This method and machine has essentially several drawbacks, namely:
En primer lugar la depresión que produce el émbolo durante su retracción facilita la entrada de aire o gas procedente de la fermentación, que debe ser posteriormente compactado para evitar variaciones significativas de volumen de masa durante la dosificación.In the first place, the depression produced by the piston during its retraction facilitates the entry of air or gas from the fermentation, which must be subsequently compacted to avoid significant variations in mass volume during dosing.
En segundo lugar es difícil modificar la tasa de dosificación, es decir que para que la máquina suministre dosis de distinto volumen, es necesario modificar mecánicamente el recorrido del embolo de dosificación. - Además, cada dosificación requiere dos operaciones, una de carga y otra de descarga, mediante un movimiento alternativo, lo que redunda en una gran lentitud de funcionamiento respecto a lo deseable.Secondly, it is difficult to modify the dosage rate, that is, in order for the machine to deliver doses of different volumes, it is necessary to mechanically modify the path of the dosing plunger. - In addition, each dosage requires two operations, one of loading and the other of unloading, by means of an alternative movement, which results in a great slow operation with respect to the desirable.
Las máquinas de émbolo tienen una gran fricción con las paredes de las cámaras, lo que produce un calentamiento excesivo de la masa en contacto, y como solución a dicho calentamiento se lubrica por medio de aceites lubricantes que están en contacto con la dicha masa, que aún siendo aceites comestible produce un efecto indeseado de combinación de la masa con un aceite que no debía formar parte de ella. Estas máquinas, además, producen desgarros en las fibras de la masa debido al arrastre de ésta cuando se introduce en la cámara separándose del la masa de la tolva, y también cuando se produce un extruído hacia la boca de salida de la dosis de masa. La invención que proponemos se refiere a un método para la dosificación de masas y pastas alimentarias, y una máquina correspondiente, que presenta ventajas respecto a los antecedentes, por cuanto regula el flujo por medio de un panel de control, el flujo de carga / descarga es continuo, y no existe un calentamiento significativo de la masa.The piston machines have a great friction with the walls of the chambers, which produces an excessive heating of the contact mass, and as a solution to said heating it is lubricated by means of lubricating oils that are in contact with the said mass, which Even being edible oils, it produces an unwanted effect of combining the dough with an oil that should not be part of it. These machines also produce tears in the fibers of the dough due to the drag of the dough when it is introduced into the chamber separating from the mass of the hopper, and also when an extrudate is produced towards the outlet of the mass dose. The invention that we propose refers to a method for the dosing of dough and pasta, and a corresponding machine, which has advantages over the background, since it regulates the flow through a control panel, the flow of loading / unloading It is continuous, and there is no significant heating of the dough.
El método que se describe, está llevado a cabo por las siguientes operaciones: un suministro de masa o pasta por medio de una tolva suministradora (al igual que en los antecedentes) opcionalmente una bombeo de la masa por medio de una máquina bombeadora rotativa de paletas sobre un segundo mecanismo impulsor, que conlleva el traslado de la masa desde la embocadura de la tolva hasta una posición de salida en concordancia con un segundo mecanismo de bombeo, y un control del par de empuje de la masa en dicha máquina bombeadora sobre el mecanismo impulsor - un bombeo volumétrico por medio de un mecanismo impulsor hacia una zona de salida, el empuje de dicho mecanismo impulsor realizado preferentemente por medio de unas paletas situadas sobre un rotor.^ Dicho bombeo produce una compresión de los gases existentes en la masa o junto a ella, por lo que reduciendo su volumen, la densidad de la masa en fase de dosificación es sustancialmente estable. - un medio de control del movimiento y paradas de los medios de empuje del mecanismo impulsor, - una compactación de la masa en una boquilla de salida, un medio de control de al menos un medio de bloqueo de la masa para su compactación y de corte de dicha masa, en el extremo de la boquilla de salida,The method described is carried out by the following operations: a supply of dough or paste by means of a supply hopper (as in the background) optionally a pumping of the dough by means of a rotary vane pumping machine on a second drive mechanism, which involves the transfer of the dough from the hopper mouth to an outlet position in accordance with a second pumping mechanism, and a control of the thrust torque of the dough in said pumping machine on the mechanism impeller - a volumetric pumping by means of an impeller mechanism towards an outlet zone, the thrust of said impeller mechanism preferably carried out by means of vanes located on a rotor. ^ This pumping produces a compression of the gases existing in the mass or next to it, so by reducing its volume, the density of the mass in the dosing phase is substantially stable. - a means for controlling the movement and stops of the pushing means of the drive mechanism, - a compaction of the mass in an outlet nozzle, a means of controlling at least one means of blocking the mass for compaction and cutting of said mass, at the end of the outlet nozzle,
El método requiere el debido control de la presión de la cámara que determina el empuje de la masa hacia la máquina bombeadora de la masa hacia el mecanismo de salida.The method requires due control of the chamber pressure that determines the thrust of the dough towards the dough pumping machine towards the exit mechanism.
Además, el método incluye una compactación de la masa bombeada sobre la zona de salida, lo cual es llevado a cabo por medio de un cambio de geometría en el conducto de salida.In addition, the method includes a compaction of the mass pumped over the outlet zone, which is carried out by means of a change of geometry in the outlet duct.
El método incluye un medio de control del corte de la masa respecto al movimiento de la máquina bombeadora, de modo que cuando el medio de corte está cortando la masa no se produce avance o empuje de ésta. También incluye un medio de control del volumen de masa que es desplazada entre corte y corte, y que determina la dosis unitaria.The method includes a means of controlling the cutting of the dough with respect to the movement of the pumping machine, so that when the cutting means is cutting the dough there is no advance or thrust thereof. It also includes a means of controlling the volume of mass that is displaced between cutting and cutting, and which determines the unit dose.
Se refiere también la presente invención a un mecanismo impulsor o máquina dosificadora de masa o pasta alimentaria, que presenta un medio impulsor rotativo, provisto de un rotor provisto a su vez de unas paletas de empuje, actuando dichas paletas sobre unas paredes externas, produciendo en su giro un desplazamiento volumétrico de la masa o pasta alimentaria, hasta impulsarlo a una boquilla de salida. Las paletas cortan la masa sin producir desgarros.The present invention also relates to an impeller or metering machine for dough or food paste, which has a rotating impeller means, provided with a rotor provided with thrust vanes, said vanes acting on external walls, producing its turn a volumetric displacement of the dough or food paste, until it is pushed to an outlet nozzle. The vanes cut the dough without producing tears.

En la figura 5 vemos una vista en perspectiva del rotor de la figuraIn Figure 4 we see a side view of the inner rotor, also common to both bodies. In figure 5 we see a perspective view of the rotor of the figure
4.Four.
En la figura 6 vemos el rotor de la figura 4 desde un punto de vista lateral, en el que están situadas unas paletas de empuje de la masa o pasta alimentaria. En la figura 7 vemos un perfil de leva que define el recorrido en extensión o retracción de cada una de las paletas provistas en el rotor, en función de su posición de giro, correspondiente a la unidad dosificadora.In figure 6 we see the rotor of figure 4 from a lateral point of view, in which there are thrust vanes of the dough or food paste. In figure 7 we see a cam profile that defines the extension or retraction of each one of the vanes provided in the rotor, depending on its turning position, corresponding to the dosing unit.
En la figura 8 vemos un perfil de leva que define el recorrido en extensión o retracción de cada una de las paletas provistas en el rotor, en función de su posición de giro, correspondiente a la unidad alimentadora de bombeo.In Figure 8 we see a cam profile that defines the extension or retraction path of each of the vanes provided in the rotor, depending on their rotation position, corresponding to the pumping feeder unit.
En la figura 9 vemos un detalle desde una vista lateral, de una paleta de las provistas en el rotor de la figura 4.In Figure 9 we see a detail from a side view of a vane provided in the rotor of Figure 4.
En la figura 10 vemos un detalle desde una vista lateral, de la paleta de la figura 9 situada sobre una de las ranuras provistas en el rotor de la figura 4, en posición retraída.In figure 10 we see a detail from a side view of the vane of figure 9 located on one of the slots provided in the rotor of figure 4, in a retracted position.
En la figura 11 vemos un detalle desde una vista lateral, de la paleta de la figura nueve, situada sobre una de las ranuras provistas en el rotor de la figura 4, en posición extendida.In figure 11 we see a detail from a side view of the vane of figure nine, located on one of the grooves provided in the rotor of figure 4, in an extended position.
En la figura 12 vemos un detalle de la geometría de la boquilla de salida de la unidad dosificadora, de la masa o pasta alimentaria, entendido que dicha geometría corresponde al hueco interior.In figure 12 we see a detail of the geometry of the outlet nozzle of the dosing unit, of the food dough or paste, understood that said geometry corresponds to the inner hollow.
En la figura 13, vemos un detalle en perspectiva en el que se aprecia la boca de salida de la boquilla de salida, y un ejemplo de una cuchilla de corte de la masa o pasta alimentaria.In figure 13, we see a detail in perspective in which appreciate the outlet mouth of the outlet nozzle, and an example of a dough cutting blade or food paste.
En la figura 14, vemos una vista general en perspectiva del conjunto de las unidades alimentadora de bombeo y de dosificación, articuladas respecto a un eje excéntrico, en posición accesible.In figure 14, we see a general perspective view of the set of the pumping and dosing feeder units, articulated with respect to an eccentric axis, in an accessible position.
De acuerdo con la realización mostrada en dichas figuras, vemos con 1 el cuerpo exterior de la unidad de dosificación que tiene una cámara interior 2, una boca de entrada 3 a dicha unidad, un rotor 4 portador de un conjunto de paletas 5 empujadoras de la masa o pasta alimentaria contenida en su interior. En el giro del rotor 4, las paletas definen un conjunto de huecos 32 (uno entre cada par) el los que la masa contenida en cada uno de ellos, es desplazada junto con el avance de las paletas 5, de modo que alcanzada una posición próxima a un rascador 33, la paleta correspondiente se retrae y oculta (continuando el empuje por la paleta siguiente, cuyo hueco está también lleno de masa) y la masa que estaba en dicho hueco, por el empuje producido por la siguiente paleta es impulsada hacia una boquilla de salida 6. Es de destacar que al menos dos paletas 5 estarán cerrando la cámara 2, de modo que siempre se producirá empuje aún cuando la paleta 5 próxima al rascador 33 situado en la zona de la boquilla de salida 6 sea retraída. La unidad alimentadora de bombeo, presenta también un cuerpo exterior 7 que define una cámara interior 8, con una correspondiente boca de entrada 9 y una correspondiente boca de salida 10. Al igual que en la unidad de dosificación, la unidad alimentadora de bombeo dispone también un rotor 11, provisto de paletas. Cuando la masa o pasta alimentaria llena el hueco existente entre el par de paletas 12 situadas en la boca de entrada 9 y éstas 12 inician su giro junto con el rotor 11, la masa correspondiente también se desplaza por el empuje de las dichas paletas, de modo, al igual que en la unidad dosificadora, que al menos una paleta 12 esté produciendo el empuje sobre la masa o pasta alimentaria. Puesto que el desplazamiento volumétrico de ambas unidades alimentadora de bombeo y dosificadora ha de ser igual en cada una de ellas (no puede entrar más de lo que sale, ni viceversa), no debe forzarse el movimiento de la unidad alimentadora en exceso sobre la dosificadora lo que no produciría sino deterioro en el conjunto, por lo que se realiza un control del movimiento en la unidad dosificadora, y un control del par de empuje (que determina una presión de empuje) para la unidad alimentadora de bombeo. Según se aprecia en la figura 3, y según una vista frontal interior, vemos a ambos lados el cuerpo de la unidad (tanto la alimentadora de bombeo como la dosificadora) el cuerpo correspondiente 1 o 7, entre los que se sitúa el rotor 4 u 11. Vemos también unas ranuras dispuestas concéntricamente a dicho rotor 4 u 11, y un aro de refuerzo 14 en cada uno de los lados para reforzar el perfil del dicho rotor 4 u 11, que de otro modo quedaría debilitado debido al mecanizado pasante de dichas ranuras, dicho aro de refuerzo 14 actuando contra una junta 15 (en ambos lados) de estanquidad.According to the embodiment shown in said figures, we see with 1 the outer body of the dosing unit having an inner chamber 2, an inlet mouth 3 to said unit, a rotor 4 carrying a set of pusher vanes 5 of the food dough or paste contained inside. In the rotation of the rotor 4, the vanes define a set of gaps 32 (one between each pair) in which the mass contained in each of them is displaced together with the advance of the vanes 5, so that a position reached next to a scraper 33, the corresponding vane retracts and hides (continuing the thrust by the next vane, whose gap is also full of mass) and the mass that was in said recess, by the thrust produced by the next vane is driven towards an outlet nozzle 6. It is noteworthy that at least two vanes 5 will be closing the chamber 2, so that thrust will always occur even when the vane 5 close to the scraper 33 located in the area of the outlet nozzle 6 is retracted. The pumping feeder unit also has an external body 7 defining an inner chamber 8, with a corresponding inlet 9 and a corresponding outlet 10. As in the dosing unit, the pumping unit also has a rotor 11, provided with vanes. When the food dough or paste fills the gap between the pair of vanes 12 located in the inlet mouth 9 and these 12 begin their rotation together with the rotor 11, the corresponding mass is also displaced by the thrust of said vanes, of so, as in the dosing unit, that at least one vane 12 is producing the thrust on the dough or pasta. Since the volumetric displacement of both pumping and dosing units must be the same in each of them (it cannot enter more than it comes out, nor vice versa), the movement of the the feeder unit in excess over the dosing unit which would only produce deterioration in the assembly, so that a movement control is carried out in the dosing unit, and a control of the thrust torque (which determines a thrust pressure) for the unit pumping feeder. As shown in Figure 3, and according to an internal front view, we see on both sides the body of the unit (both the pumping feeder and the dosing) the corresponding body 1 or 7, between which the rotor 4 u is located 11. We also see grooves concentrically arranged to said rotor 4 or 11, and a reinforcement ring 14 on each side to reinforce the profile of said rotor 4 or 11, which would otherwise be weakened due to the through machining of said grooves, said reinforcement ring 14 acting against a seal 15 (on both sides) of tightness.
En la figura 4 se aprecia el mecanizado del rotor 4, 11, en el que las ranuras 13 son radiales. El rotor presenta un rebaje sobre el que se coloca la cabeza 16 del eje 18, que presenta un hueco en combinación con el dicho rotor 4, 11, para la colocación de un chavetero 17, que proporciona a su vez medios de empuje para el rotor 4, 11.Figure 4 shows the machining of the rotor 4, 11, in which the grooves 13 are radial. The rotor has a recess on which the head 16 of the shaft 18 is placed, which has a gap in combination with said rotor 4, 11, for the placement of a keyway 17, which in turn provides thrust means for the rotor 4, 11.
En la vista de la figura 5 vemos el rotor 4, 11 provisto de sus correspondientes ranuras 13, así como un rebaje 19 practicado en cada una de sus caras laterales para la colocación de la cabeza de inserción 16 del eje 18, con el correspondiente hueco en cabeza y hueco para la colocación de una chaveta. El rotor 4, 11 dispone un alojamiento en zona próxima a su periferia para el alojamiento de un rascador de las paletas 5, 12 cuando son extendidas o retraídas.In the view of figure 5 we see the rotor 4, 11 provided with its corresponding grooves 13, as well as a recess 19 practiced on each of its lateral faces for the placement of the insertion head 16 of the axis 18, with the corresponding recess head and hole for the placement of a key. The rotor 4, 11 has a housing in an area close to its periphery for the accommodation of a scraper of the vanes 5, 12 when they are extended or retracted.
En la vista de la figura 6, observamos nuevamente el rotor visto desde uno de sus lados, en el que observamos el aro de refuerzo 14 que cierra las ranuras al tiempo que permite que las paletas 5, 12 puedan deslizarse en movimiento de retracción y extensión, donde 18 es el eje de tracción, con su cabeza insertada sobre el rotor. Cada una de las paletas dispone en sus extremos interiores (próximos al eje) laterales unos rodillos o ruedas 21, seguidores de leva, que les permite deslizarse arriba y abajo por medio de su circulación sobre unas levas correspondientes situadas a ambos lados de la cámara (y del rotor 4, 11).In the view of Figure 6, we look again at the rotor seen from one of its sides, in which we observe the reinforcement ring 14 that closes the grooves while allowing vanes 5, 12 to slide in retraction and extension movement. , where 18 is the drive axle, with its head inserted over the rotor. Each of the vanes has lateral rollers or wheels 21, cam followers on its inner inner ends (next to the axis), which allows them to slide up and down by means of their circulation on corresponding cams located on both sides of the chamber ( and of the rotor 4, 11).
Podemos ver dichas levas 22, de la unidad dosificadora, y 24, de la unidad alimentadora de bombeo, así como sus correspondientes perfiles 23 y 25, que corresponden al recorrido exterior del perfil de cada una de las cámaras 2 yWe can see these cams 22, of the dosing unit, and 24, of the pumping feeder unit, as well as their corresponding profiles 23 and 25, which correspond to the outer path of the profile of each of the chambers 2 and
8.8.
La paleta 5, 12 es preferentemente simétrica y recta, aunque podría ser asimétrica o curva, y presenta un extremo rascador 26 y un soporte 27The vane 5, 12 is preferably symmetrical and straight, although it could be asymmetric or curved, and has a scraper end 26 and a support 27
(normalmente un orificio roscado) para la sujeción de las ruedas o rodillos 21.(normally a threaded hole) for fastening the wheels or rollers 21.
En la figura 10 vemos una paleta 5, 12 situada en una ranura 13 existente en el rotor 4, 11, retraída hacia el eje 18, cuando el perfil de leva 23, 25 en su posición de giro, y a causa del desplazamiento provocado por el giro de las ruedas o rodillos 21 sobre dicho perfil adopta una posición próxima al eje 18.In figure 10 we see a vane 5, 12 located in a groove 13 in the rotor 4, 11, retracted towards the axis 18, when the cam profile 23, 25 in its rotation position, and because of the displacement caused by the rotation of the wheels or rollers 21 on said profile adopts a position close to the axis 18.
Con 20 observamos un rascador de paleta que impide que cuando la paleta es retraída penetre masa o pasta alimentaria adherida a ella.With 20 we observe a palette scraper that prevents when the pallet is retracted it will penetrate dough or food paste attached to it.
Por el contrario, en la figura 11 vemos la paleta 5, 12 de la figuraOn the contrary, in figure 11 we see palette 5, 12 of the figure
10, por efecto del seguimiento del perfil de leva 23, 25 por las ruedas o rodillos 21 solidarias al extremo interior lateral de las paletas, cuando dicha leva 23, 25 adopta una posición extendida, en la que se ve también el correspondiente rascador10, as a result of the monitoring of the cam profile 23, 25 by the wheels or rollers 21 connected to the inner side end of the vanes, when said cam 23, 25 adopts an extended position, in which the corresponding scraper is also seen
20.twenty.
Como queda explicado, el extremo rascador 26 de la paleta 5, 12 está prácticamente en contacto con el perfil de la cámara 2, 8, salvo en las zonas de entrada 3, 9 y salida 6, 10, donde no hay perfil correspondiente. En las zonas de los rascadores 33, 34 las paletas se ocultan para superar el obstáculo, siempre manteniendo el rascado sobre el correspondiente perfil para mantener a su vez una suficiente estanquidad.As explained, the scraper end 26 of the vane 5, 12 is practically in contact with the profile of the chamber 2, 8, except in the input areas 3, 9 and output 6, 10, where there is no corresponding profile. In the areas of the scrapers 33, 34 the vanes are hidden to overcome the obstacle, always maintaining the scratch on the corresponding profile to maintain a sufficient tightness.
La figura 12 nos muestra una vista del hueco que forma la boquilla de salida 6, de acuerdo con una realización preferente, en la que manteniéndose la sección constante, se produce un cambio de geometría que facilita la cohesión de la masa que había sido seccionada por las paletas 5, 12. Vemos con 28 una geometría correspondiente a la parte interior, mientras que con 29 vemos la boca exterior. La boca de salida permitirá el corte de una cierta cantidad de masa o pasta alimentaria en función del movimiento de avance del rotor 4 de impulsión de las paletas 5, y en sincronismo con el movimiento de corte de una cuchilla 30, que de acuerdo con la realización representada se designa con 31.Figure 12 shows a view of the gap that forms the outlet nozzle 6, in accordance with a preferred embodiment, in which the constant section is maintained, there is a change in geometry that facilitates the cohesion of the mass that had been sectioned by palettes 5, 12. We see with 28 a geometry corresponding to the inner part, while with 29 we see the outer mouth. The outlet mouth will allow the cutting of a certain amount of dough or food paste depending on the advance movement of the rotor 4 of the vanes 5, and in synchronism with the cutting movement of a blade 30, which according to the embodiment represented is designated 31.
En la vista en perspectiva de la figura 14 vemos un montaje de las unidades dosificadora e alimentadora de bombeo, en que ambas unidades están montadas en una sola máquina, en las que apreciamos un eje de articulación 35 entre ellas, que permite el acceso para la correspondiente limpieza o mantenimiento.In the perspective view of figure 14 we see an assembly of the metering and pumping feeder units, in which both units are mounted on a single machine, in which we can see an articulation axis 35 between them, which allows access for corresponding cleaning or maintenance.
En resumen, observamos un mecanismo impulsor de masa o pasta alimentaria en el que según una sección transversal vemos una cámara cuyas paredes forman un perfil interior, presentando dicha cámara una zona de entrada, vista en las figuras en la parte superior, y una zona de salida, que en la figura 1 queda en la parte derecha. El perfil exterior citado de la dicha cámara es recorrido por el extremo de las paletas 5, 12 situadas en el rotor 4, 11 que gira sobre su eje central de giro. El rotor dispone unas ranuras 13 sobre las que cada una de las paletas 5, 12 es susceptible de desplazamiento en extensión y retracción respecto a dicho rotor, de modo conforme se produce el giro del rotor las paletas se extienden (para el empuje de la masa o pasta alimentaria), o se retraen para no tropezar con el rascador que forma en el lugar adecuado el perfil de la cámara. La salida de la masa de la cámara de bombeo se produce por efecto de un rascador que actúa sobre el rotor, de modo que cuando la masa alcanza la posición de dicho rascador es impulsada hacia una boquilla de salida, ya que no puede proseguir otro camino.In summary, we observe a drive mechanism of dough or food paste in which according to a cross section we see a chamber whose walls form an internal profile, said chamber presenting an entrance area, seen in the figures at the top, and an area of exit, which in figure 1 is on the right side. The aforementioned outer profile of said chamber is traversed by the end of the vanes 5, 12 located in the rotor 4, 11 which rotates on its central axis of rotation. The rotor has grooves 13 on which each of the vanes 5, 12 is susceptible to displacement in extension and retraction with respect to said rotor, so that the rotor rotates, the vanes extend (for the thrust of the mass or food paste), or they retract to avoid tripping over the scraper that forms the camera profile in the right place. The output of the mass of the pumping chamber is produced by the effect of a scraper that acts on the rotor, so that when the mass reaches the position of said scraper it is propelled towards an outlet nozzle, since another path cannot continue .
Es deseable que al menos una paleta esté siempre en contacto con el perfil interior de la cámara, de modo que no pueda existir retomo o falta del requerido empuje de la masa. El movimiento de extensión y retracción de las paletas respecto al rotor se produce por efecto del seguimiento de un eje de seguimiento solidario a cada una de las paletas provisto de un rodillo de leva o seguidor, respecto a al menos una leva de seguimiento, situada preferentemente a ambos lados del rotor.It is desirable that at least one vane is always in contact with the inner profile of the chamber, so that there can be no return or lack of the required thrust of the mass. The movement of extension and retraction of the vanes with respect to the rotor is produced by the effect of tracking a follow-up axis integral to each of the vanes provided with a cam roller or follower, with respect to at least one tracking cam, preferably located on both sides of the rotor.
La dosificación de la masa se lleva a cabo mediante el avance controlado del giro del rotor con sus paletas, de modo que un cierto avance supone un cierto volumen conocido. El control de dicho avance nos permite definir unidades de volumen, que serán conducidas a la boquilla de salida, y posteriormente cortadas.The dosage of the mass is carried out by the controlled advance of the rotation of the rotor with its vanes, so that a certain advance supposes a certain known volume. The control of this advance allows us to define volume units, which will be conducted to the outlet nozzle, and subsequently cut.
Dado que el funcionamiento de la máquina bombeadora es continuo, la masa que va a ser cortada es empujada por la masa que se encuentra en la boquilla de salida e indirectamente por las paletas del rotor. La boquilla de salida tiene un perfil variable para producir la compactación de la masa dividida por las paletas a su entrada en el rotor de impulsión, aunque es deseable que el área de la sección permanezca constante para evitar tensiones sobre la masa.Since the operation of the pumping machine is continuous, the mass to be cut is pushed by the mass found in the outlet nozzle and indirectly by the rotor blades. The outlet nozzle has a variable profile to produce the compaction of the mass divided by the vanes upon its entry into the drive rotor, although it is desirable that the area of the section remain constant to avoid tensions on the mass.
La boquilla de salida dispone un mecanismo de corte en sincronismo con el movimiento del rotor, de modo que el rotor impulsa la masa cuando el mecanismo de corte está abierto, y para cuando se produce el corte con el volumen deseado.The outlet nozzle has a cutting mechanism in synchronism with the movement of the rotor, so that the rotor drives the mass when the cutting mechanism is open, and when the cut occurs with the desired volume.
El mecanismo descrito permite una gran velocidad y fiabilidad de dosificación.The mechanism described allows high speed and dosing reliability.
Además la presente invención se extiende a un mecanismo bombeador de la masa o pasta alimentaria para ser utilizado con una máquina dosificadora, que mejora las prestaciones de la máquina dosificadora citada.Furthermore, the present invention extends to a pumping mechanism of the dough or food paste for use with a dosing machine, which improves the performance of the aforementioned dosing machine.
Consiste dicho mecanismo en un conjunto semejante a la máquina dosificadora ya descrita, en el que tenemos una cámara provista de un perfil interior, que según una sección presenta unas paredes laterales sobre las que se disponen un rascador y una cámara de avance, una zona de entrada y una zona de salida. La zona de entrada estará normalmente en la parte superior y estará vinculada a un elemento suministrador, tal como una tolva de alimentación. La zona de salida estará preferentemente en la parte inferior, y será conectada a una unidad dosificadora. Al igual que dicha máquina dosificadora, el mecanismo bombeador de masa o pasta alimentaria de la invención, dispone un rotor interior provisto de un conjunto de paletas impulsoras de la masa, dichas paletas susceptibles de una extensión o retracción en función de la posición instantánea del rotor en la cámara, de modo que en las zonas que no sean la entrada o la salida el extremo externo de dichas paletas esté en contacto o casi en contacto con el perfil de la dicha cámara, y que cuando las paletas hayan superado la zona de salida se retraigan para salvar el rascador del rotor. Cuando están combinados la máquina bombeadora con el mecanismo impulsor dosificador, es aconsejable que los rotores presenten giros opuestos que por la continuidad de flujo eviten desgarros en la masa.This mechanism consists of an assembly similar to the dosing machine already described, in which we have a chamber provided with an internal profile, which according to a section has some side walls on which a scraper and an advance chamber are arranged, an area of entrance and an exit zone. The entrance area will normally be at the top and will be linked to a supply element, such as a feed hopper. The exit zone will preferably be at the bottom, and will be connected to a dosing unit. Like said dosing machine, the dough pumping mechanism of the invention has an internal rotor provided with a set of dough driving vanes, said vanes susceptible to extension or retraction depending on the instantaneous position of the rotor in the chamber, so that in areas other than the entrance or exit the external end of said vanes is in contact or almost in contact with the profile of said chamber, and that when the vanes have exceeded the exit zone retract to save the rotor scraper. When the pumping machine is combined with the metering drive mechanism, it is advisable that the rotors have opposite turns that, due to the continuity of flow, prevent tearing in the dough.
La máquina bombeadora y la máquina dosificadora pueden estar articuladas entre sí permitiendo un fácil acceso para limpieza o mantenimiento.The pumping machine and the dosing machine can be articulated with each other allowing easy access for cleaning or maintenance.
Tanto en una como en la otra máquina, las paletas presentan un dispositivo rascador dispuesto en el rotor, de modo que cuando dichas paletas son retraídas se impida la penetración de masa en el interior del rotor.In both one and the other machine, the vanes have a scraper device arranged in the rotor, so that when said vanes are retracted, the penetration of mass inside the rotor is prevented.
Los rotores presentan en sus lados unas juntas de estanquidad contra la pared de la correspondiente cámara que impide también la entrada de masa sobre dicho rotor.The rotors have on their sides sealing gaskets against the wall of the corresponding chamber that also prevents the entry of mass on said rotor.
Resulta evidente que para grandes producciones pueden situarse un conjunto de máquinas bombeadoras dosificadoras en paralelo, montadas en un mismo cuerpo o en cuerpos separados, o boquillas de salida múltiples. Es de destacar, que las precisiones indicadas han de ser consideradas dentro de la invención de un modo extensivo, quedando dentro del ámbito de protección solicitado las posibles variaciones que se puedan realizar sin alterar la esencialidad de los conjuntos descritos. It is clear that for large productions a set of parallel metering pumping machines can be placed, mounted on the same or separate bodies, or multiple outlet nozzles. It is noteworthy, that the stated requirements must be considered within the invention in an extensive way, leaving within the scope of protection requested the possible variations that can be made without altering the essentiality of the described sets.
