Description

Dispositivo introductor para el suministro de cuerpos laminares en una estación de impresión gráfica  Introducing device for the supply of laminar bodies in a graphic printing station
MEMORIA DESCRIPTIVA DESCRIPTIVE MEMORY
OBJETO DE LA INVENCIÓN OBJECT OF THE INVENTION
La presente solicitud de patente de invención tiene por objeto el registro de un dispositivo introductor para el suministro de cuerpos laminares en una estación de impresión gráfica que incorpora notables innovaciones y ventajas. The purpose of the present invention patent application is to register an introducer device for the supply of laminar bodies in a graphic printing station that incorporates notable innovations and advantages.
Más concretamente, la invención propone el desarrollo de un dispositivo introductor previsto para la manipulación, por ejemplo, de planchas de cartón de diferentes tamaños para ser posteriormente tratadas en una estación de impresión digital de una forma continua y con la mínima separación entre las planchas de cartón, por lo que aumenta la productividad. More specifically, the invention proposes the development of an introducing device intended for the manipulation, for example, of cardboard plates of different sizes to be subsequently treated in a digital printing station in a continuous manner and with the minimum separation between the plates of cardboard, so productivity increases.
ANTECEDENTES DE LA INVENCIÓN BACKGROUND OF THE INVENTION
En la impresión de planchas de cartón o material laminar es bien conocida en la actualidad la aplicación de la técnica por impresión flexográfica. Esta técnica consiste esencialmente el hacer pasar la plancha de cartón entre dos rodillos uno de los cuales denominaremos porta- cliché donde se adhiere el cliché que tiene el patrón de impresión deseado. El funcionamiento de esta técnica consiste en que cada vuelta del rodillo porta-cliché imprime una plancha de cartón. In the printing of cardboard sheets or sheet material, the application of the technique by flexographic printing is now well known. This technique consists essentially of passing the cardboard plate between two rollers, one of which we will call a cliché holder where the cliché with the desired printing pattern adheres. The operation of this technique is that each round of the cliché roller prints a cardboard plate.
En la impresión flexográfica el perímetro del rodillo porta-cliché determina el desarrollo de la máquina, es decir, la distancia entre el inicio de una plancha y el inicio de la siguiente plancha. Esta distancia debe permanecer constante independientemente de la longitud de las planchas. Para ello, en una instalación de fabricación de planchas de cartón provistas de una estación de impresión flexográfica se dispone de un dispositivo introductor que se coordina con la velocidad de giro del rodillo porta-cliché, permitiendo solamente introducir una plancha por cada vuelta del rodillo porta-cliché. Por este motivo anterior, cuando se imprimen planchas de dimensiones pequeñas la distancia entre ellas es mayor que cuando lleva a cabo la impresión de planchas de mayores dimensiones. Si bien la impresión flexográfica obtiene unos resultados de impresión aceptables, cada vez más se está extendiendo en uso de la impresión digital también para la impresión de planchas de cartón. La impresión digital presenta una serie de ventajas frente a la impresión flexográfica, tales como el hecho de que permite imprimir planchas sin límite de la longitud de las mismas, un grupo impresor puede disponer de los cuatro colores básicos a diferencia de la impresión flexográfica donde es necesario el uso de cuatro cuerpos impresores, cada uno de ellos con uno de los colores. Otra ventaja también de la impresión digital es que no existe la necesidad de clichés puesto que el cambio de patrón en la impresión se realiza de forma digital y por lo tanto de forma instantánea con el consiguiente ahorro de tiempo, fabricación, almacenamiento y mantenimiento así como el hecho de presentar una calidad de impresión superior. No obstante, la velocidad de la impresión digital es aún muy inferior a la flexográfica, por ello, y teniendo en cuenta las diferencias entre ambas tecnologías, es necesario un introductor de planchas adaptado a los requerimientos de la impresión digital y que a la vez aumente su productividad. In flexographic printing, the perimeter of the cliché roller determines the development of the machine, that is, the distance between the beginning of one plate and the beginning of the next plate. This distance must remain constant regardless of the length of the plates. For this, in an installation for the manufacture of cardboard plates provided with a flexographic printing station, there is an introducing device that coordinates with the rotation speed of the cliché roller, allowing only one plate to be introduced for each turn of the porta roller -cliche. For this reason, when printing plates of small dimensions, the distance between them is greater than when printing plates of larger dimensions. Although flexographic printing obtains acceptable printing results, it is increasingly being extended in the use of digital printing also for the printing of cardboard plates. Digital printing has a series of advantages over flexographic printing, such as the fact that it allows printing plates without limit of the length of them, a printing group can have the four basic colors unlike flexographic printing where it is It is necessary to use four printing bodies, each with one of the colors. Another advantage also of digital printing is that there is no need for clichés since the change of pattern in the printing is done digitally and therefore instantaneously with the consequent saving of time, manufacturing, storage and maintenance as well as Presenting superior print quality. However, the speed of digital printing is still much lower than the flexographic one, therefore, and taking into account the differences between both technologies, a plate introducer adapted to the requirements of digital printing is necessary and at the same time increase Your productivity
DESCRIPCIÓN DE LA INVENCIÓN DESCRIPTION OF THE INVENTION
La presente invención se ha desarrollado con el fin de proporcionar un dispositivo introductor que se configura como una novedad dentro del campo de aplicación y resuelve los inconvenientes anteriormente mencionados, aportando, además, otras ventajas adicionales que serán evidentes a partir de la descripción que se acompaña a continuación. The present invention has been developed in order to provide an introducing device that is configured as a novelty within the field of application and resolves the aforementioned drawbacks, also providing other additional advantages that will be apparent from the accompanying description. then.
Es por lo tanto un objeto de la presente invención proporcionar un dispositivo introductor para el suministro de cuerpos laminares en una estación de impresión gráfica, en particular previsto para introducir simultáneamente cuerpos laminares de igual o distinto tamaño al mismo nivel y de forma paralela entre sí y con la capacidad de depositar tales cuerpos laminares uno detrás de otro de una forma continua, con la mínima separación posible, de modo que el borde de inicio de un cuerpo laminar está en contacto o prácticamente en contacto con el borde final del cuerpo laminar anterior. Tal introductor es del tipo que comprende al menos una zona de almacenamiento para cuerpos laminares donde cuerpos laminares son dispuestos en una pila vertical, estando la zona de almacenamiento provista de medios de desplazamiento para extraer un cuerpo laminar desde la zona de almacenamiento a un medio transportador externo vinculado con la estación de impresión gráfica. Más en particular, la invención se caracteriza por el hecho de que los medios de desplazamiento están ubicados en una bancada movible con respecto a una bancada fija dispuesta previamente a la estación de impresión gráfica, comprendiendo tales medios de desplazamiento unas correas de arrastre giratorias provistas de una pluralidad de orificios pasantes a lo largo de las mismas y accionadas por medios motores, estando vinculadas a un dispositivo aspirador de vacío; y en el que la bancada fija presenta unos rodillos de arrastre o correas aspirantes a través de los cuales pasan los cuerpos laminares. Además, la bancada movible presenta unos medios de tope que están en contacto con la parte delantera de los cuerpos laminares. It is therefore an object of the present invention to provide an introducer device for the supply of laminar bodies in a graphic printing station, in particular intended to simultaneously introduce laminar bodies of the same or different size at the same level and parallel to each other and with the ability to deposit such laminar bodies one after the other in a continuous manner, with the minimum possible separation, so that the leading edge of a laminar body is in contact or practically in contact with the final edge of the anterior laminar body. Such an introducer is of the type comprising at least one storage area for laminar bodies where laminar bodies are arranged in a vertical stack, the storage area provided with displacement means for extracting a laminar body from the storage area to a conveyor means external linked to the graphic printing station. More particularly, the invention is characterized by the fact that the displacement means are located on a movable bed with respect to a fixed bed previously arranged to the graphic printing station, said displacement means comprising rotating drive belts provided with a plurality of through holes therein and driven by motor means, being linked to a vacuum aspiration device; and in which the fixed bed has trailing rollers or suction belts through which the laminar bodies pass. In addition, the movable bed has stop means that are in contact with the front of the sheet bodies.
Gracias a estas características, se obtiene un dispositivo introductor que permite que los cuerpos laminares, indistintamente de su tamaño (en particular, anchura y longitud) entren en la estación de impresión digital de forma continua habiendo la mínima distancia entre ellos de modo que se reduce el tiempo en el que los cabezales de la impresora digital están inactivos, por lo que se incrementa el ratio de productividad de la estación de impresión digital. La disposición de las correas de arrastre con un dispositivo aspirador de vacío evita que las planchas o cuerpos laminares resbalen a diferencia del uso de una correa convencional, asegurando el agarre necesario de la plancha durante la acción de aceleración de la propia plancha hasta conseguir que el inicio o borde delantero del cuerpo laminar (por ejemplo, una plancha de cartón) esté en contacto o muy próximo al extremo final o borde posterior del cuerpo laminar adyacente a éste antes de llegar a los rodillos de arrastre que giran a la misma velocidad que una cinta transportadora asociada a la estación de impresión. Thanks to these characteristics, an introducing device is obtained that allows the laminar bodies, regardless of their size (in particular, width and length) to enter the digital printing station continuously, having the minimum distance between them so that it is reduced the time in which the heads of the digital printer are inactive, so that the productivity ratio of the digital printing station is increased. The arrangement of the drag belts with a vacuum aspiration device prevents the plates or sheet bodies from slipping unlike the use of a conventional belt, ensuring the necessary grip of the plate during the acceleration action of the plate itself until the plate is accelerated. start or leading edge of the sheet body (for example, a cardboard sheet) is in contact or very close to the end end or rear edge of the sheet body adjacent thereto before reaching the drive rollers that rotate at the same speed as a Conveyor belt associated with the printing station.
Otra ventaja no menos importante es que puede variarse la distancia (o valor de longitud) existente entre los medios de tope y los rodillos de arrastre al disponerse de una bancada movible que puede alejarse o acercarse con respecto a la bancada fija provista de los rodillos de arrastre, resultando adecuado para cuerpos laminares de gran longitud ya que un aumento de la distancia anteriormente citada permite aumentar el tiempo disponible para que la parte delantera de un cuerpo laminar alcance la parte posterior del cuerpo laminar anterior disminuyendo así la aceleración y las fuerzas derivadas de ésta. Another advantage is that the distance (or length value) between the stop means and the drive rollers can be varied by having a movable bed that can move away or approach with respect to the fixed bed provided with the rollers of dragging, being suitable for laminar bodies of great length since an increase in the aforementioned distance allows to increase the available time for the front part of a laminar body to reach the back of the anterior laminar body thus decreasing the acceleration and forces derived from is.
Se sobreentenderá en esta memoria que la parte delantera del cuerpo laminar se refiere al borde o arista situada delante tomando como referencia la dirección de avance de los cuerpos laminares desde el dispositivo introductor hacia la estación de impresión. Preferentemente, la bancada movible es desplazable por medio de un sistema cremallera vinculado con una superficie base o suelo. It will be understood in this specification that the front part of the laminar body refers to the edge or edge located in front taking as reference the direction of advance of the laminar bodies from the introducer device towards the printing station. Preferably, the movable bed is movable by means of a rack system linked to a base surface or floor.
En una realización particularmente preferida, el citado sistema cremallera se basa en la utilización de una rueda dentada motorizada acoplada a la bancada movible, engranando dicha rueda dentada sobre una cremallera fijada en la superficie base o suelo, tratándose por ello de un sistema de sencilla construcción y bajo mantenimiento. In a particularly preferred embodiment, said rack system is based on the use of a motorized cogwheel coupled to the movable bed, said cogwheel gearing on a rack fixed on the base surface or floor, thus being a simple construction system. and low maintenance.
En una realización preferida, el dispositivo introductor presenta dos zonas de almacenamiento dispuestas de una forma paralela entre si, estando cada una de las zonas de almacenamiento provista de medios de desplazamiento independientes. De esta manera, es posible incrementar la capacidad de carga o trabajo del dispositivo introductor dado que pueden imprimirse de forma simultánea dos hileras de cuerpos laminares de igual o distinta dimensión. In a preferred embodiment, the introducer device has two storage areas arranged parallel to each other, each of the storage areas being provided with independent travel means. In this way, it is possible to increase the loading or working capacity of the introducer device since two rows of laminar bodies of the same or different dimensions can be printed simultaneously.
Ventajosamente, cada uno de los medios de desplazamiento está accionados por medios motores independientes entre sí. Advantageously, each of the displacement means is driven by independent motor means.
Ventajosamente, la zona de almacenamiento está lateralmente delimitada por unas posicionadores desplazables axialmente en una dirección transversal con respecto a la dirección de desplazamiento de los cuerpos laminares, que permiten posicionar correctamente las planchas de cartón sobre las zonas de almacenamiento. Advantageously, the storage area is laterally delimited by axially movable positioners in a transverse direction with respect to the direction of travel of the sheet bodies, which allow the cardboard plates to be positioned correctly on the storage areas.
Según otro aspecto de la invención, las correas de arrastre giratorias están montadas en conjuntos tanqueta que pueden desplazarse en una dirección transversal con respecto a la dirección de desplazamiento de los cuerpos laminares de manera que pueden situarse en la posición más adecuada en función de las medidas de los cuerpos laminares de manipular. Cada uno de dichos conjuntos tanqueta comprenden al menos tres poleas dispuestas en una disposición triangular, vista lateralmente, siendo una de ellas una polea motriz que transmite el movimiento a la correa de arrastre giratoria. According to another aspect of the invention, the rotating drive belts are mounted in tanker assemblies that can move in a transverse direction with respect to the direction of travel of the laminar bodies so that they can be placed in the most suitable position depending on the measurements of the laminar bodies to manipulate. Each of said tanker assemblies comprises at least three pulleys arranged in a triangular arrangement, seen laterally, one of them being a driving pulley that transmits the movement to the rotating drive belt.
En una realización particular, los medios motores consisten en un servomotor acoplado a un eje transmisor que transmite el movimiento a la polea motriz giratoria sobre la que se acopla la correa de arrastre giratoria. Ventajosamente, el dispositivo introductor puede incluir un sensor detector para la detección de una situación de deslizamiento de un cuerpo laminar con respecto a una correa de arrastre giratoria, estando dicho sensor detector situado entre los medios de tope que están en contacto con la parte delantera de los cuerpos laminares y los rodillos de arrastre, de modo que dicho deslizamiento puede ser corregido modificando los parámetros de funcionamiento de los medios motores. De este modo, se puede mantener de una forma constante y determinada la distancia existente entre cuerpos laminares. In a particular embodiment, the drive means consist of a servomotor coupled to a drive shaft that transmits the movement to the rotating drive pulley on which the rotating drive belt is coupled. Advantageously, the introducer device may include a detector sensor for detecting a sliding situation of a laminar body with respect to a rotating drive belt, said detector sensor being located between the stop means which are in contact with the front part of the laminar bodies and the drag rollers, so that said sliding can be corrected by modifying the operating parameters of the motor means. In this way, the distance between laminar bodies can be maintained in a constant and determined way.

DESCRIPTION OF A PREFERRED EMBODIMENT In view of the aforementioned figures and, in accordance with the numbering adopted, an example of a preferred embodiment of the invention can be observed therein, which comprises the parts and elements indicated and described in detail by continuation.
Así, tal como se aprecia en las figuras, el dispositivo introductor está previsto para el suministro de planchas de cartón hacia una estación de impresión gráfica digital para ser impresas, por ejemplo, con información publicitaria, indicaciones sobre los productos a ser trasportar en las cajas, etc. Thus, as shown in the figures, the introducing device is provided for the supply of cardboard sheets to a digital graphic printing station to be printed, for example, with advertising information, indications on the products to be transported in the boxes. , etc.
Este dispositivo introductor comprende un par de zonas de almacenamiento (1 ) adyacentes situadas en una bancada movible (2) y previstas para colocarse en cada una de ellas de una forma apilada una pluralidad de planchas de cartón (3). Cada una de las zonas de almacenamiento (1 ) está provista de unos medios de desplazamiento, que se detallarán más adelante, que permiten realizar la extracción de las planchas de cartón (3) desde cada una de las zonas de almacenamiento (1 ) hacia una cinta transportadora (4) vinculada con la estación de impresión gráfica digital, indicada de forma general con la referencia (5). En la presente memoria no se va a entrar en mayor detalle en la descripción de la estación de impresión gráfica digital (5) dado que puede ser cualquiera de las actualmente disponibles en el mercado y no forma parte de la propia invención. Cada una de las zonas de almacenamiento (1 ) está lateralmente delimitada por unos posicionadores (6) que pueden desplazarse axialmente con ayuda de unos medios de guiado en una dirección transversal con respecto a la dirección de desplazamiento de las planchas de cartón (3) que se indica mediante flechas (f) en la figura 2, permitiendo su ajuste a las dimensiones de las planchas de cartón. This introducing device comprises a pair of adjacent storage areas (1) located on a movable bed (2) and intended to be placed in each of them in a stacked a plurality of cardboard sheets (3). Each of the storage areas (1) is provided with means of movement, which will be detailed below, which allow the removal of the cardboard sheets (3) from each of the storage areas (1) towards a Conveyor belt (4) linked to the digital graphic printing station, indicated in general with reference (5). In the present specification, the description of the digital graphic printing station (5) is not going to go into greater detail since it can be any of those currently available in the market and is not part of the invention itself. Each of the storage areas (1) is laterally delimited by positioners (6) that can be moved axially with the aid of guiding means in a transverse direction with respect to the direction of movement of the cardboard plates (3) which It is indicated by arrows (f) in Figure 2, allowing its adjustment to the dimensions of the cardboard sheets.
Haciendo ahora particular referencia a los medios de desplazamiento, éstos comprenden para cada una de las zonas de almacenamiento (1 ) de dos conjuntos tanqueta, indicados de forma general con la referencia (7), que están provistos de unas correas de arrastre giratorias (8) que incluyen una pluralidad de orificios pasantes (9) a lo largo de las mismas. Tales correas de arrastre giratorias (8) son accionadas por tres poleas (10) que forman parte del conjunto tanqueta (7), siendo una de las poleas una polea motriz que transmite el movimiento a la correa de arrastre giratoria (8) por la acción de un servomotor (1 1 ). Será bien evidente por un experto en la materia que el número de poleas (10) puede ser variable. Cada una de las correas de arrastre giratorias (8) está vinculada a un dispositivo aspirador de vacío que tiene una cámara de vacío (12) que pretende evitar el deslizamiento de las planchas de cartón (3) con respecto a las correas de arrastre giratorias (8) cuando son expulsadas fuera de la bancada movible (2) al succionar la plancha de cartón (3) a través de los orificios pasantes (9) de las correas de arrastre giratorias (8). With particular reference now to the displacement means, these comprise for each of the storage areas (1) of two tanker assemblies, generally indicated by reference (7), which are provided with rotating drive belts (8 ) which include a plurality of through holes (9) therein. Such rotating drive belts (8) are driven by three pulleys (10) that are part of the tanker assembly (7), one of the pulleys being a driving pulley that transmits the movement to the rotating drive belt (8) by action of a servomotor (1 1). It will be quite evident by one skilled in the art that the number of pulleys (10) can be variable. Each of the rotating drive belts (8) is linked to a vacuum aspiration device that has a vacuum chamber (12) which aims to prevent the sliding of the cardboard plates (3) with respect to the rotating drive belts ( 8) when they are ejected out of the movable bed (2) by sucking the cardboard plate (3) through the through holes (9) of the rotating drive belts (8).
Además, la bancada movible (2) presenta unos medios de tope frontales definidos por unas placas que están en contacto con la parte delantera de los cuerpos laminares mientras que una bancada fija (13) dispuesta después de la bancada movible (en la dirección de funcionamiento) presenta un par de rodillos de arrastre (14) enfrentados entre sí en un plano vertical que dejan un espacio a través del cual pasan las planchas de cartón (3) procedentes de las zonas de almacenamiento (1 ). In addition, the movable bed (2) has front stop means defined by plates that are in contact with the front part of the laminar bodies while a fixed bed (13) arranged after the movable bed (in the operating direction ) has a pair of drive rollers (14) facing each other in a plane vertical leaving a space through which the cardboard sheets (3) from the storage areas (1) pass.
Adicionalmente, la bancada movible (2) también presenta unos medios de tope posteriores que están en contacto con la parte posterior de las planchas de cartón (3), los cuales incluyen un rodillos (15) soportados sobre una estructura de soporte (16) que comprende un brazo sensiblemente en forma de "L". Ventajosamente, la estructura de soporte (16) está acoplada a un sistema cremallera que presenta una pletina cremallera (17) fijada en la estructura de soporte (16) que engrana con una rueda dentada (20) acoplada en la bancada movible (2). La disposición de sistema cremallera permite regular la distancia existente entre los medios de tope frontal anteriormente mencionados y los medios de tope posteriores. Mencionar que los rodillos (15) pueden regularse en altura gracias a la disposición de un sistema cremallera secundario (18) dispuesto en la estructura de soporte (16). Como puede verse con mayor claridad en la figura 3, la bancada movible (2) puede desplazarse longitudinalmente en la dirección de avance de las planchas de cartón (3) a través de un sistema cremallera que presenta una cremallera (18), acoplada en el suelo, que engrana con una rueda dentada (19) motorizada acoplada a la bancada movible. Para asegurar el posicionamiento de la bancada movible (2) sobre la cremallera (18) se incluye un sistema de enclavamiento de accionamiento vertical, indicado de forma general con la referencia (21 ), tal que en una posición de bloqueo impide el desplazamiento involuntario de la bancada movible (2) sobre la citada cremallera (18). Additionally, the movable bed (2) also has rear stop means which are in contact with the back of the cardboard sheets (3), which include a roller (15) supported on a support structure (16) that It comprises a substantially "L" shaped arm. Advantageously, the support structure (16) is coupled to a rack system that has a rack plate (17) fixed to the support structure (16) that engages with a cogwheel (20) coupled to the movable bed (2). The rack system arrangement allows to regulate the distance between the front stop means mentioned above and the rear stop means. Mention that the rollers (15) can be adjusted in height thanks to the provision of a secondary rack system (18) arranged in the support structure (16). As can be seen more clearly in Figure 3, the movable bed (2) can move longitudinally in the direction of advance of the cardboard sheets (3) through a rack system that has a rack (18), coupled in the ground, which meshes with a motorized cogwheel (19) coupled to the movable bed. To ensure the positioning of the movable bed (2) on the rack (18), a vertical drive interlocking system is included, generally indicated by reference (21), such that in a locked position it prevents the involuntary movement of the movable bed (2) on said rack (18).
Además, en la bancada movible (2) del dispositivo introductor de la presente descripción está montado un sensor (22) previsto para la detección de una situación de deslizamiento de las planchas de cartón (3) con respecto a las correas de arrastre giratorias (8). In addition, a sensor (22) is mounted on the movable bed (2) of the introducing device of the present description for detecting a sliding situation of the cardboard sheets (3) with respect to the rotating drive belts (8 ).
Para evitar que una plancha previa a contactar con las correas de arrastre giratorias (8) entre en contacto con tales correas de arrastre giratorias (8) cuando aún se está deslizando una plancha de cartón (3) en dirección hacia los rodillos de arrastre (14), con el consiguiente rozamiento entre la cara inferior de la plancha de cartón (3) a ser introducida y las correas de arrastre giratorias (8), ventajosamente en la zona de almacenamiento (1 ) se dispone de pletinas elevadoras (23) sobre las cuales descansan las planchas de cartón (3) en una condición previa a contactar con los medios de desplazamiento, siendo tales pletinas elevadoras (23) accionadas por unos medios de accionamiento que se detallan más adelante. Justo en el momento en que la parte posterior de la plancha entra en contacto con los rodillos de arrastre (14) las pletinas elevadoras (23) pasan a una posición elevada con respecto a la posición de la correa de arrastre giratoria (8) con lo que la correa de arrastre giratoria (8) puede reducir su velocidad hasta detenerse por completo. En este momento la pletina elevadora (23) desciende dejando la pila de cartón nuevamente sobre las correas de arrastre giratorias (8) sin que se produzca roce entre las plancha de cartón a introducir y la correa. To prevent a pre-contact plate with the rotating drive belts (8) from coming into contact with such rotating drive belts (8) while a cardboard plate (3) is still sliding in the direction of the drive rollers (14 ), with the consequent friction between the underside of the cardboard plate (3) to be introduced and the rotating drive belts (8), advantageously in the storage area (1) there are lifting plates (23) on the which the cardboard plates (3) rest in a condition prior to contacting the displacement means, such lifting plates (23) being actuated by actuation means that are detailed more ahead. Just at the moment when the back of the plate comes into contact with the drive rollers (14) the lifting plates (23) go to an elevated position with respect to the position of the rotating drive belt (8) with that the rotating drive belt (8) can reduce its speed until it stops completely. At this time the lifting plate (23) descends leaving the cardboard stack again on the rotating drive belts (8) without friction between the cardboard plates to be introduced and the belt.
Más en particular, tales medios de accionamiento que permiten llevan a cabo la elevación y/o descenso de la pletina elevadora (23) comprenden un par de conjuntos accionadores rotatorios, presentando cada uno de ellos un eje de giro (24) unido a un mecanismo de leva (25) que está vinculado por la parte superior de la pletina elevadora (23), tal como puede verse más claramente en la figura 3. Los detalles, las formas, las dimensiones y demás elementos accesorios, empleados en la fabricación del dispositivo introductor de la invención podrán ser convenientemente sustituidos por otros que no se aparten del ámbito definido por las reivindicaciones que se incluyen a continuación. More particularly, such drive means that allow the lifting and / or lowering of the lifting plate (23) to be carried out comprise a pair of rotary actuator assemblies, each of which has a rotation axis (24) attached to a mechanism of cam (25) which is linked by the upper part of the lifting plate (23), as can be seen more clearly in figure 3. The details, shapes, dimensions and other accessory elements used in the manufacture of the device Introducer of the invention may be conveniently substituted by others that do not depart from the scope defined by the claims set forth below.
