El objeto de la presente invención es una máquina modular higiénica cortadora y pesadora de queso en porciones, de componentes principales modulares extraíbles y la no existencia de ninguno de ellos sobre el queso en el proceso que este realiza dentro de la máquina, susceptibles de contaminación del producto. The object of the present invention is a hygienic modular machine for cutting and weighing cheese into portions, with removable modular main components and the absence of any of them on the cheese in the process that it performs inside the machine, susceptible to contamination of the product.
ANTECEDENTES DE LA INVENCIÓN BACKGROUND OF THE INVENTION
En la actualidad el consumo de queso en porciones es una realidad, y la venta de este formato se extiende por todas las cadenas de distribución. Today the consumption of cheese in portions is a reality, and the sale of this format is spread throughout all distribution chains.
Para realizar este formato y subsanar los inconvenientes derivados del mismo, se conocen por ejemplo los modelos de utilidad U200402125, U200402597 y U200500836 referidos a máquinas cortadoras y pesadoras de queso en porciones, las cuales principalmente cumplen esta función. Estás responden a un criterio basado fundamentalmente en el rendimiento y la funcionalidad. In order to make this format and correct the drawbacks derived from it, the utility models U200402125, U200402597 and U200500836 are known, for example, referring to slicing and weighing machines for cheese into portions, which mainly fulfill this function. These respond to a criterion based primarily on performance and functionality.
Pero desde un tiempo a esta parte el mercado está demandando a las industrias queseras una mayor concienciación para reducir el riesgo de brotes de contaminación microbiológica que va unido a unas normas sanitarias nacionales de obligado cumplimiento cada vez más estrictas. Cuando se intenta llegar a mercados internacionales estas normas sanitarias se endurecen todavía más, haciendo muy difícil la línea de negocio en la exportación a estos países. But for some time now, the market has been demanding greater awareness from cheese industries to reduce the risk of microbiological contamination outbreaks, which is linked to increasingly stringent national sanitary regulations that must be complied with. When trying to reach international markets, these sanitary standards become even more stringent, making the line of business in exporting to these countries very difficult.
Una máquina diseñada higiénicamente como la del presente modelo de utilidad tiene beneficios multitudinarios, tales como ayudar a proteger el bienestar del consumidor y la reputación de la marca de una empresa al aumentar la seguridad alimentaria y reducir el riesgo de retiro del mercado, el equipo higiénico puede ayudar con el cumplimiento normativo y de análisis de riesgos y puntos críticos de control. Pero eso no es todo: invertir en equipos diseñados de forma higiénica también puede conducir a ahorros de costos a largo plazo y una mayor eficiencia operativa al permitir que se extiendan los tiempos de ejecución, acortar los tiempos de limpieza, reducir el uso de químicos y agua de limpieza y los costos de mantenimiento. A hygienically designed machine like the one in this utility model has massive benefits, such as helping to protect consumer welfare and a company's brand reputation by increasing food safety and reducing the risk of recall, hygienic equipment can help with regulatory compliance and risk analysis and critical control points. But that's not all - investing in hygienically designed equipment can also lead to long-term cost savings and increased operational efficiency by enabling to extend run times, shorten cleaning times, reduce the use of cleaning chemicals and water, and reduce maintenance costs.
Para cumplir todas estas exigencias del mercado, las industrias están utilizando una serie de detergentes y productos de limpieza cada vez más agresivos. Mayor limpieza en profundidad de cada una de las partes de la máquina, donde el fácil acceso a todas las partes de la máquina se hace vital para poder completar una limpieza más cualitativa y efectiva. En este mundo tan competitivo se necesita que las máquinas tengan pocos tiempos de parada en la producción, por ello desde es punto de vista de mantenimiento y reparación, se necesitan máquinas accesibles para los operarios. To meet all these market demands, industries are using a series of increasingly aggressive detergents and cleaning products. Greater in-depth cleaning of each of the parts of the machine, where easy access to all parts of the machine is vital to be able to complete a more qualitative and effective cleaning. In this highly competitive world it is necessary for machines to have few downtime in production, therefore from a maintenance and repair point of view, accessible machines are needed for operators.
Lograr todo esto en el diseño de una máquina conlleva una serie de retos técnicos en la integración del diseño con el entorno completo de la producción de alimentos para minimizar el riesgo de contaminación y permitir una limpieza y saneamiento efectivo. Debido a que existen muchas restricciones, tales como: poderse limpiar a nivel microbiológico, materiales a utilizar compatibles con el producto, el medio ambiente y los productos químicos de limpieza/desinfección, elementos comerciales en muchas ocasiones no compatibles, sistemas fácilmente accesibles para inspección, mantenimiento, limpieza y saneamiento sin el uso de herramientas, autodrenante, sin huecos y recovecos, y por su puesto segura, etc. Accomplishing all of this in a machine design brings a number of technical challenges in integrating the design with the entire food production environment to minimize the risk of contamination and enable effective cleaning and sanitation. Because there are many restrictions, such as: being able to clean at a microbiological level, materials to be used compatible with the product, the environment and the cleaning / disinfection chemicals, commercial elements that are often not compatible, easily accessible systems for inspection, maintenance, cleaning and sanitation without the use of tools, self-draining, without holes and nooks, and of course safe, etc.
Estos inconvenientes y necesidades se subsanan mediante la utilización de la máquina de la presente invención. These drawbacks and needs are overcome by using the machine of the present invention.

Determinando de manera óptima el peso de las porciones obtenidas mediante un corte rápido, preciso, limpio y exento de rebabas o migas, mediante cuchilla bien mecánica o de ultrasonidos. En todos los procesos que realiza el queso dentro de la máquina, éste discurre sin que exista ningún elemento, sistema o dispositivo encima de su superficie. No existe la posibilidad de que sobre el caiga algún tipo de fluido o partículas procedente de los mismos, disminuyendo drásticamente el riesgo de contaminación y solventando así el mayor de los problemas descritos. The machine of the present invention makes it possible to cut cheese into portions in the different stages of maturation. Determining in an optimal way the weight of the portions obtained by means of a fast, precise, clean cut and free of burrs or crumbs, using either a mechanical or ultrasonic blade. In all the processes carried out by the cheese inside the machine, it runs without there being any element, system or device on its surface. There is no possibility of some type of fluid or particles falling on it, drastically reducing the risk of contamination and thus solving the greatest of the problems described.
De acuerdo con la presente invención otra de las mejoras que se proponen es construir el bastidor autoportante en perfil de chapa totalmente abierto (1) con soldaduras a ras, sin hoyos, grietas y corrosión, evitando tubos huecos donde no siempre están sellados herméticamente, con los problemas contaminantes que ello conlleva. Autodrenante para garantizar que el líquido, que puede albergar y promover el crecimiento de bacterias no se acumule. According to the present invention, another of the proposed improvements is to build the self-supporting frame in a fully open sheet metal profile (1) with flush welds, without holes, cracks and corrosion, avoiding hollow tubes where they are not always hermetically sealed, with the contaminating problems that this entails.

A continuación, el queso pasa de forma unitaria desde el transportador higiénico retráctil de alimentación (2) al sistema modular de pesaje dinámico (3). Formado por un transportador higiénico (31) de capacidad para un queso, de idénticas características al transportador anterior. Montado sobre una célula de carga (39) totalmente de acero inoxidable y grado de protección IP69K, conectada al PLC o unidad de control quedando registrado su peso para su posterior corte en porciones. El sistema es modular, se puede colocar y extraer todo el conjunto, para labores de limpieza exhaustiva o de reparación y mantenimiento mucho más rápido y efectivo. También existe la posibilidad de extraer solamente el transportador (31), de la parte fija (35) donde se sitúa la célula de carga (39). Todo esto resuelve otro de los problemas que se presentan en la actualidad. Next, the cheese passes in a unitary way from the hygienic retractable feeding conveyor (2) to the modular dynamic weighing system (3). Formed by a hygienic conveyor (31) with a capacity for a cheese, with identical characteristics to the previous conveyor. Mounted on a load cell (39) totally made of stainless steel and IP69K degree of protection, connected to the PLC or control unit, its weight being recorded for later cutting into portions. The system is modular, the entire assembly can be placed and removed, for exhaustive cleaning or repair and maintenance tasks much faster and more effective. There is also the possibility of extracting only the conveyor (31), from the fixed part (35) where the load cell (39) is located. All this solves another of the problems that arise today.
Para colocar el queso en el sistema extraíble de centrado y giro (6) antes de realizar el corte, se utilizar un carro de alimentación a corte (4). Este es un carro accionado mediante correa dentada (45) y motorreductor higiénico IP69K (44) realizando un movimiento alternativo, sobre éste van montados el brazo mete quesos (42) y el brazo saca quesos (43), ambos actúan solidariamente, aunque son fácilmente desmontables para labores de limpieza y mantenimiento. Es decir, mientras el mete- quesos coloca es queso desde el sistema de pesaje en un plato soporte (69a) perteneciente al conjunto soporte queso (69) dentro del sistema (6), el saca-quesos conduce el queso ya cortado en porciones colocándolo en el transportador higiénico de salida (8). Es un carro que optimiza recursos porque está accionado por único motorreductor (44). Debido a que todo el grupo de centrado está situado en la parte inferior de queso y tiene que elevarse para poder girar el queso, existe un hueco entre el plato soporte (69a) y el sistema de pesaje dinámico (3) y el transportador (8), esto se solventa mediante la mesa de transferencia (5), que dispone de unas placas móviles (52) accionadas mediante un solo cilindro neumático (53) que actúa sobre un sistema que permite abrir y cerrar ambas placas móviles a la vez. Como todos los elementos anteriores es modular, se puede extraer fácilmente todo el conjunto para labores de limpieza profunda y para labores de reparación y mantenimiento. To place the cheese in the removable centering and turning system (6) before cutting, a cut feeding carriage (4) will be used. This is a trolley driven by a toothed belt (45) and a hygienic IP69K gear motor (44) performing an alternative movement, on which the arm for putting cheese (42) and the arm for removing cheese (43) are mounted, both act jointly, although they are easily removable for cleaning and maintenance. That is, while the metecheese places the cheese from the weighing system on a support plate (69a) belonging to the cheese support assembly (69) within the system (6), the cheese extractor conveys the cheese already cut into portions, placing it on the hygienic outlet conveyor (8). It is a carriage that optimizes resources because it is driven by a single gear motor (44). Because the entire centering group is located in the lower part of the cheese and has to be raised to be able to turn the cheese, there is a gap between the support plate (69a) and the dynamic weighing system (3) and the conveyor (8 ), this is solved by the transfer table (5), which has mobile plates (52) actuated by a single pneumatic cylinder (53) that acts on a system that allows both mobile plates to be opened and closed at the same time. Like all the previous elements, it is modular, the entire assembly can be easily removed for deep cleaning tasks and for repair and maintenance tasks.
La mejora de mayor relevancia y complejidad técnica de la presente invención es el sistema extraíble de centrado y corte (6), ésta permite que no exista ningún sistema encima de los quesos susceptible de contaminar con líquidos o partículas a lo largo de toda la máquina, caracterizando a toda ella y ofreciendo una circunstancia muy ventajosa sobre las máquinas existentes. Dispone de un conjunto soporte queso (69) formado por un mástil vertical (69b) y por un plato soporte (69a), donde sobre este último se deposita el queso para realizar el corte, un sistema de sujeción y giro del queso (61). El fijado del queso se realiza mediante un sistema con servomotor (64) totalmente inoxidable IP69K a través de sistema de corona-piñón exterior, que permite ejercer distinta presión según la maduración del queso y ajustarse diametralmente más o menos según el tamaño del queso. Esto se traduce en mejoras en la manipulación del producto y reducción de tiempos al optimizarse el movimiento, que representa una gran ventaja sobre los sistemas existentes de palanca accionada neumáticamente. El giro del conjunto (61) se realiza también mediante conjunto servomotor (66) totalmente en acero inoxidable IP69K mediante sistema corona-piñón interior. Este sistema al no tener que estar suspendido requiere un servomotor de menor tamaño, economizando materiales y recursos. El conjunto (61) va montado sobre un carro de elevación (65), accionado por un solo cilindro neumático (68), mejorando los sistemas actuales que utilizan varios cilindros de elevación, conlleva ventajas de mantenimiento y repuesto. Todo el sistema (6) forma un único conjunto que es extraíble totalmente de la máquina mediante un carro de extracción (67), ya que es un sistema relativamente complejo y que necesita ajustes precisos. Por ello, al estar totalmente fuera de la máquina todas las labores de limpieza profunda y reparación o mantenimiento se realizarán de manera efectiva, rápida y cómoda, esto representa una ventaja muy importante respecto a los sistemas existentes. The most relevant and technically complex improvement of the present invention is the removable centering and cutting system (6), this allows that there is no system on top of the cheeses that is likely to contaminate with liquids or particles throughout the entire machine, characterizing all of it and offering a very advantageous circumstance over existing machines. It has a cheese support assembly (69) formed by a vertical pole (69b) and a support plate (69a), where the cheese is deposited on the latter to perform the cut, a system for holding and turning the cheese (61) . The cheese is fixed by means of a system with a fully stainless IP69K servomotor (64) through the external crown-pinion system, which allows different pressure to be exerted according to the maturation of the cheese and to be diametrically adjusted more or less according to the size of the cheese. This translates into improvements in product handling and time reduction by optimizing movement, which represents a great advantage over existing pneumatically actuated lever systems. The rotation of the assembly (61) is also carried out by means of a servomotor assembly (66) totally made of IP69K stainless steel by means of an internal crown-pinion system. Since this system does not have to be suspended, it requires a smaller servo motor, saving materials and resources. The assembly (61) is mounted on a lifting carriage (65), actuated by a single pneumatic cylinder (68), improving the current systems that use several lifting cylinders, it carries advantages of maintenance and replacement. The entire system (6) forms a single unit that is completely removable from the machine by means of an extraction carriage (67), since it is a relatively complex system and requires precise adjustments. Therefore, being completely outside the machine, all deep cleaning and repair or maintenance tasks will be carried out effectively, quickly and comfortably, this represents a very important advantage over existing systems.
El proceso es el siguiente: una vez depositado el queso en el plato (69a), el conjuntoThe process is as follows: once the cheese has been deposited on the plate (69a), the whole
(61) es elevado hasta la altura del queso mediante cilindro (68). Un grupo de brazos(61) is raised to the height of the cheese by means of a cylinder (68). A group of arms
(62) se cierra fijando el queso, una vez fijado lo gira mediante sistema (63) la amplitud angular correspondiente al tamaño de porción seleccionada previamente, para ser cortado mediante el sistema modular de corte servo-controlado (7) (62) is closed by fixing the cheese, once fixed it is rotated by means of the system (63) the angular amplitude corresponding to the previously selected portion size, to be cut by the modular servo-controlled cutting system (7)
En este punto procedemos a exponer otra de las mejoras de la presente invención, el sistema modular de corte servo-controlado (7). Es formado por un conjunto modular que puede montarse y desmontarse todo de una vez. Solventa uno de los problemas del excesivo tiempo en labores de reparación y mantenimiento, en el cambio de guías lineales, rodamientos, etc., en los sistemas existentes mediante conjunto motorreductor biela-manivela. Dispone de un accionamiento mediante servomotor (75) que actúa mediante sistema piñón-cremallera sobre el carro soporte de cuchilla (72). Esto permite controlar el movimiento de la cuchilla de corte (73), bien sea cuchilla mecánica o por ultrasonidos dependiendo del tipo de queso, optimizando el movimiento alternativo de corte, es decir, moviéndose lo necesario sin tener que ir a posiciones fijar como el sistema biela-manivela. Cuando la máquina esta parada o no operativa la cuchilla tiene una posición de reposo en la cual, queda totalmente guardada mediante una barrera física (98) accionada mediante cilindro neumático. Esto protege al operario en todo momento de cortes en labores de limpieza y mantenimiento aumentando la seguridad de la máquina, evitando cortes accidentales. El corte efectuado es preciso, recto y sin rebabas. At this point we proceed to expose another of the improvements of the present invention, the modular servo-controlled cutting system (7). It is made up of a modular set that can be assembled and disassembled all at once. It solves one of the problems of excessive time in repair and maintenance work, in the change of linear guides, bearings, etc., in existing systems by means of a connecting rod-crank gear motor assembly. It has a drive by means of a servomotor (75) that acts by means of a rack and pinion system on the blade support carriage (72). This makes it possible to control the movement of the cutting blade (73), either mechanical or ultrasonic blade depending on the type of cheese, optimizing the alternative cutting movement, that is, moving as necessary without having to go to fixed positions like the system. gear crank. When the machine is stopped or inoperative, the blade has a rest position in which it is fully guarded by a physical barrier (98) operated by a pneumatic cylinder. This protects the operator at all times from cuts in cleaning and maintenance tasks, increasing the safety of the machine, avoiding accidental cuts. The cut made is precise, straight and without burrs.
Una vez efectuados los cortes indicados en cada queso, el grupo superior de giro (61) baja para esconderse debajo de la mesa de transferencia (5), permitiendo el paso mediante el cierre de las placas móviles (52) aproximándose al plato soporte (69), desde éste hasta el transportador de salida (8). El proceso es realizado por el empuje del brazo saca-quesos (43), y a la misma vez el brazo mete-quesos (42) colocará otro queso para que realice el proceso de corte de nuevo, optimizando el tiempo. Ambos brazos están mecanizados con forma semicircular que se adapta al perímetro del queso. Once the indicated cuts have been made in each cheese, the upper turning group (61) lowers to hide under the transfer table (5), allowing passage by closing the mobile plates (52) approaching the support plate (69 ), from this to the exit conveyor (8). The process is carried out by pushing the cheese extractor arm (43), and at the same time the cheese inserting arm (42) will place another cheese to carry out the cutting process again, optimizing time. Both arms are machined with a semicircular shape that adapts to the perimeter of the cheese.
El transportador higiénico de salida (8), dispone de una zona retráctil en la parte más exterior de la máquina para permitir el paso de operarios cuando esta esté conectada a otras líneas de la fábrica, permite también quedar totalmente incluida en el interior de máquina para el transporte evitando tener que desmontarla ganando tiempos de instalación. El modelo de construcción y funcionamiento dispone de las mismas características indicadas para el transportador de alimentación higiénico (2).The hygienic outlet conveyor (8) has a retractable area in the outermost part of the machine to allow the passage of operators when it is connected to other lines of the factory, it also allows it to be fully included inside the machine to transport avoiding having to disassemble it, saving installation time. The construction and operation model has the same characteristics indicated for the hygienic feeding conveyor (2).
Todos los cuadros eléctricos son comerciales en acero inoxidable con diseño higiénico y protección IP69K. A pesar de que todos los elementos son fácilmente desmontables, toda la máquina puede ser lavada íntegramente en el lugar de su instalación debido a su diseño con materiales aptos para ello. All electrical panels are commercial in stainless steel with hygienic design and IP69K protection. Despite the fact that all the elements are easily removable, the entire machine can be washed in its entirety at the place of installation due to its design with suitable materials.

REALIZACIÓN PREFERENTE DE LA INVENCIÓN PREFERRED EMBODIMENT OF THE INVENTION
La máquina de la invención permite realizar al queso el recorrido dentro de la misma indicado en la figura 1. La máquina según podemos observar en las figuras 2 y 3 comprende los siguientes elementos: The machine of the invention allows the cheese to carry out the path within it indicated in figure 1. The machine, as we can see in figures 2 and 3, comprises the following elements:
Un bastidor autoportante (1), según muestra la figura 4, sobre el que se disponen el resto de elementos y conjuntos. Montado sobre unos pies higiénicos regulables en altura. A self-supporting frame (1), as shown in figure 4, on which the rest of the elements and assemblies are arranged. Mounted on height-adjustable hygienic feet.
Un transportador higiénico de alimentación (2), según muestra la figura 5, para la entrada de quesos enteros al proceso de corte, a su vez, puede ir almacenando quesos a la espera de realizarse el proceso de corte. Dispone de banda modular higiénica (21) accionado por moto-tambor higiénico (20) IP69K con piñón mecanizado sobre el mismo, rodillos conducidos y de liberación tensión (23). La parte de la cola, mas exterior de la máquina dispone de un sistema retráctil (22), que consta de un bastidor móvil con unos patines guías que se deslizan sobre unas ruedas (24). Que permiten que recogida quede totalmente en el interior de la máquina permitiendo el paso cuando este enlazada con otras líneas existentes en la fábrica y para su fácil y transporte, dispone de un sistema de bloqueo en las posiciones finales, no representado. Todos los elementos son desmontables sin herramientas. A hygienic feeding conveyor (2), as shown in figure 5, for the entrance of whole cheeses to the cutting process, in turn, can store cheeses while waiting for the cutting process to take place. It has a hygienic modular band (21) driven by a hygienic motor-drum (20) IP69K with a machined pinion on it, driven rollers and tension release (23). The outermost part of the tail of the machine has a retractable system (22), which consists of a mobile frame with guide skates that slide on wheels (24). That allow the collection to remain completely inside the machine allowing the passage when it is linked to other existing lines in the factory and for its easy transport, it has a locking system in the final positions, not shown. All elements are removable without tools.
A continuación de este va instalado un sistema modular de pesaje dinámico (3), según figura 6. Cuyo transportador higiénico (31), de las mismas características que el transportador (2), banda modular higiénica (31b), accionada mediante moto- tambor (31a) IP69K y rodillos conducidos (31c), desmontaje sin herramientas, está sustentado sobre un soporte (35), con una célula de carga (39) destinada a registrar el peso unitario de cada queso antes de pasar al proceso de corte, y comunicarse con el PLC de la máquina instalado en el cuadro eléctrico (10) de la máquina, registrando el peso de dicho queso. El transportador (31) se puede desacoplar rápidamente del sistema fijo (35), mediante los redondos (31 d) q encajan sobre las piezas (35b). Al ser modular todo el conjunto (3) puede desmontarse enteramente de la máquina. Se muestra en la figura 21. Following this is installed a modular dynamic weighing system (3), according to figure 6. Whose hygienic conveyor (31), with the same characteristics as the conveyor (2), hygienic modular belt (31b), driven by motor drum (31a) IP69K and driven rollers (31c), disassembly without tools, it is supported on a support (35), with a load cell (39) designed to record the unit weight of each cheese before going to the cutting process, and communicate with the machine's PLC installed in the machine's electrical panel (10), recording the weight of said cheese. The conveyor (31) can be quickly uncoupled from the fixed system (35), by means of the rounds (31 d) that fit on the pieces (35b). As the whole assembly (3) is modular, it can be entirely disassembled from the machine. Shown in figure 21.
Para colocar el queso en la zona de corte, se necesita un carro de alimentación a corte (4), según muestran las figuras 7 y 7A. Este es un carro doble que cuenta con un brazo mete-quesos (42) que es el encargado de transferir el queso del sistema de pesaje (3) a la zona de corte (6). Y de un brazo saca-quesos (43) destinado a conducir el queso ya cortado en porciones de la zona de corte (6) hacia el transportador higiénico de salida (8). Este carro doble (4) está accionado mediante conjunto moto- reductor (44) y correa dentada (45). Ambos brazos (42) y (43) son de rápido desmontaje. To place the cheese in the cutting area, a cutting feed carriage (4) is needed, as shown in Figures 7 and 7A. This is a double cart that has a cheese-inserting arm (42) that is in charge of transferring the cheese from the weighing system (3) to the cutting area (6). And a cheese extractor arm (43) destined to guide the cheese already cut into portions from the cutting area (6) towards the hygienic outlet conveyor (8). This double carriage (4) is driven by a motor-reducer assembly (44) and a toothed belt (45). Both arms (42) and (43) are quick to disassemble.
Debido a la existencia del sistema extraíble de centrado y giro (6) situado en la parte inferior de la máquina, existe un hueco entre el plato soporte (69a) y el sistema de pesaje (3) y entre el transportador higiénico de salida (8). Se necesita de una mesa de transferencia (5), como se puede observar en la figura 8. Dispone de dos placas móviles (52) de apertura paralela, accionadas mediante un único cilindro neumático (53), a través de un sistema (54), basado en una modificación de un plato Longworth y piñón (54a) y cremallera (54b), según muestra la figura 8A. Las placas móviles (52) se aproximan al plato soporte (69a) en la transferencia de quesos, mientras el sistema (6) se oculta bajo la mesa de transferencia (5) y se alejan cuando se realiza el proceso de centrado, giro y corte del queso, estando el sistema (6) por encima de la placa de transferencia (5). Esta mesa de transferencia (5) puede extraerse al exterior de la máquina de manera rápida y cómoda, simplemente bajando el trasportador de salida (8), liberándolo mediante las palancas de bloqueo (88), según muestra la figura 12. Due to the existence of the removable centering and turning system (6) located at the bottom of the machine, there is a gap between the support plate (69a) and the weighing system (3) and between the hygienic outlet conveyor (8 ). A transfer table (5) is needed, as can be seen in figure 8. It has two mobile plates (52) with parallel opening, activated by a single pneumatic cylinder (53), through a system (54) , based on a modification of a Longworth chainring and pinion (54a) and rack (54b), as shown in Figure 8A. The moving plates (52) approach the support plate (69a) in the transfer of cheeses, while the system (6) is hidden under the transfer table (5) and move away when the centering, turning and cutting process is carried out. of the cheese, the system (6) being above the transfer plate (5). This transfer table (5) can be extracted to the outside of the machine quickly and comfortably, simply by lowering the exit conveyor (8), releasing it by means of the locking levers (88), as shown in figure 12.
El queso ya está colocado sobre el sistema extraíble de centrado y giro (6), mostrado en la figura 9. Sobre el conjunto soporte queso (69), más concretamente sobre el plato soporte (69a), que junto al mástil vertical (69b) constituyen el conjunto soporte queso (69). Este plato (69a) es de forma circular con el diámetro suficiente para el tipo de queso a cortar, mecanizado en forma cóncava para adaptarse al queso cuyas caras circulares de apoyo no son totalmente planas, favoreciendo asé también la cohesión de las porciones durante el proceso de corte. Como se puede apreciar en la figura 18, dispone de un sistema de desmontaje inequívoco (691) rápido y que evita errores de montaje. Consta este sistema de dos ranuras mecanizadas a 180° en tamaños diferentes que encajarán en dos redondos dispuestos también a 180° de diferente diámetro, colocados en el mástil vertical (69b). Por ello solo existe una posibilidad para colocarlo. Este mástil vertical (69b) es también fácilmente extraíble del sistema (6) e igualmente solo puede colocarse en una posición Perimetralmente a este plato (69a), se dispone un conjunto giratorio de sujeción, centrado y giro para el queso, según figura 17. En respuesta al valor del peso del queso obtenido desde la célula de carga y registrado en el PLC, y habiendo seleccionado a través de la pantalla táctil de control (18) previamente el peso fijo que queremos en cada porción, o bien un número fijo de porciones en cada queso. Con ambos parámetros el PLC calcula la amplitud angular necesaria de giro. The cheese is already placed on the removable centering and turning system (6), shown in figure 9. On the cheese support assembly (69), more specifically on the support plate (69a), which together with the vertical mast (69b) constitute the cheese support assembly (69). This plate (69a) is circular in shape with sufficient diameter for the type of cheese to be cut, machined in a concave shape to adapt to cheese whose circular support faces are not totally flat, thus also favoring the cohesion of the portions during the process. cutting. As can be seen in figure 18, it has an unequivocal disassembly system (691) that is fast and avoids assembly errors. This system consists of two grooves machined at 180 ° in different sizes that will fit into two rounds also arranged at 180 ° from different diameter, placed on the vertical mast (69b). Therefore there is only one possibility to place it. This vertical mast (69b) is also easily removable from the system (6) and can also only be placed in one position Perimetrically to this plate (69a), there is a rotating assembly for fastening, centering and turning for the cheese, according to figure 17. In response to the value of the weight of the cheese obtained from the load cell and registered in the PLC, and having previously selected through the control touch screen (18) the fixed weight that we want in each portion, or a fixed number of servings on each cheese. With both parameters the PLC calculates the necessary angular amplitude of rotation.
El encargado de fijar, centrar y girar dicha amplitud angular es el grupo superior de giro (61), según figura 17, perteneciente al sistema (6), este va fijando y girando sucesivamente el queso los ángulos necesarios para que, a través del sistema modular de corte servo-controlado (7) efectúe cortes igualmente sucesivos desde una dirección fija (lateralmente, perpendiculares a la cara cilindrica), obteniendo así las porciones del tipo elegido.
