Description

MÁQUINA CERRADORA EN VACÍO PARA LATAS  EMPTY CLOSURE MACHINE FOR CAN

La presente memoria descriptiva se refiere, como su título indica, a una máquina cerradora en vacío de latas, del tipo de las utilizados en las cadenas automatizadas de la industria de conservas alimenticias para realizar el cierre de las latas una vez introducido el producto, caracterizada porque comprende una pluralidad de cabezales de cierre ubicados dentro de una cámara de vacío, con una única esclusa giratoria de entrada y salida de latas, intercalándose en la cadena de transporte de las latas como un bucle perpendicularmente dispuesto, siendo capaz de utilizar tanto latas cilindricas como no cilindricas, de formas irregulares. The present specification refers, as its title indicates, to a vacuum canning machine, of the type used in the automated chains of the canning industry to close the cans once the product has been introduced, characterized because it comprises a plurality of closing heads located inside a vacuum chamber, with a single rotating inlet and outlet lock, being inserted in the transport chain of the cans as a perpendicularly arranged loop, being able to use both cylindrical cans as non-cylindrical, irregularly shaped.

En la actualidad son ampliamente conocidas y utilizadas múltiples y variados tipos de maquinas que, intercaladas dentro de la cadena de producción, se encargan de realizar el cierre mecánico definitivo de las latas de conservas, que vienen por la cadena de transporte con la tapa ya posicionada en su lugar con un clinchado o precierre para el posicionado de la tapa. Este tipo de máquinas, como por ejemplo la descrita en el Modelo de Utilidad 1070097 "Máquina cerradora de envases", están previstas para realizar el cerrado de las latas con líquido o aire para complementar al producto alimenticio enlatado. At present, multiple and varied types of machines are widely known and used that, interspersed within the production chain, are responsible for performing the final mechanical closure of canned cans, which come through the transport chain with the lid already positioned in place with a clinching or pre-closing for the positioning of the lid. This type of machines, such as the one described in Utility Model 1070097 "Packaging closing machine", are intended to close the cans with liquid or air to complement the canned food product.

Sin embargo en la actualidad está aumentando la demanda y la necesidad de enlatar productos sin líquidos y en vacío, como por ejemplo maíz, productos cárnicos, etc., para mejorar tanto las cualidades organolépticas como su conservación. Existen algunas soluciones conocidas para realizar el cierre en vacío, como por ejemplo realizar la extracción del aire mediante un choro transversal de aire comprimido justo antes del cierre, tal y como podemos encontrar recogido en la Patente Europea 2168807 "Procedimiento y aparato para tapar latas de envase para productos alimenticios y bebidas", pero presenta los inconvenientes de ser un sistema complejo y costoso, que no proporciona un vacío suficientemente completo, únicamente son capaces de trabajar con latas de forma cilindrica, y además disminuye notablemente la velocidad de enlatado. However, the demand and the need for canning products without liquids and in vacuum, such as corn, meat products, etc., are increasing to improve both organoleptic qualities and their conservation. There are some known solutions for vacuum closing, such as air extraction by means of a transverse jet of compressed air just before closing, as we can find in European Patent 2168807 "Procedure and apparatus for covering container cans for food products and beverages", but it has the disadvantages of being a complex and expensive system, which does not provide a sufficiently complete vacuum, they are only capable of working with cans in a cylindrical manner, and also the canning speed decreases markedly.

Se han intentado buscar otras soluciones, como por ejemplo la descrita en la Patente Europea 2203516 "Máquina y procedimiento para el llenado y el precintado de recipientes" , que realizan el llenado y el cierre dentro de una zona especial de la cadena de producción cerrada y al vacío, utilizando una entrada y una salida diferenciadas para poder intercalarse dentro de los medios de transporte de la cadena de producción. Este tipo de soluciones presentan algunos problemas, como es la necesidad de mantener el vacío en una parte relativamente grande de la cadena de producción, además de necesitar dos esclusas herméticas de cierre, una de entrada y otra de salida, que originan unas pérdidas de vacío bastante importantes. Además este tipo de instalaciones únicamente son capaces de trabajar con latas de forma cilindrica, lo cual limita notablemente su utilización con productos alimenticios. Attempts have been made to find other solutions, such as the one described in European Patent 2203516 "Machine and procedure for filling and sealing containers", which perform filling and closing within a special area of the closed production chain and in a vacuum, using a differentiated input and output to be able to be inserted within the means of transport of the production chain. These types of solutions present some problems, such as the need to maintain the vacuum in a relatively large part of the production chain, in addition to needing two hermetic closing locks, one inlet and one outlet, which cause vacuum losses. quite important. In addition, these types of installations are only capable of working with cans in a cylindrical shape, which significantly limits their use with food products.

Para solventar la problemática existente en la actualidad en el cierre de conservas al vacío se ha ideado la máquina cerradora en vacío de latas objeto de la presente invención, la cual comprende una pluralidad de cabezales de cierre ubicados dentro de una cámara de vacío, con una única esclusa giratoria de entrada y salida de latas, intercalándose en la los medios de transporte de la cadena de producción de las latas como un bucle perpendicularmente dispuesto a dichos medios de transporte. La esclusa giratoria o estrella adopta la forma de un cilindro de reducida altura, con unos alojamientos laterales de forma coincidente con la forma de las latas a utilizar, que gira de forma sincronizada con los medios de transporte de las latas dentro de un marco con una abertura rectangular coincidente con la sección transversal de la esclusa giratoria, quedando asegurado el cierre hermético mediante unas planchas elásticas de cierre intercaladas entre la esclusa giratoria y el marco, que se adaptan por presión permitiendo el giro de la esclusa pero evitando la entrada de aire al interior de la cámara de vacío. El acceso desde los medios de transporte a la esclusa giratoria dispone de una rampa para elevar la lata al acceder a los alojamientos y ajustaría perfectamente dentro de dicho alojamiento, garantizando la hermeticidad a su paso por la esclusa giratoria. In order to solve the problem currently existing in the canning of vacuum canning, the vacuum closing machine of cans object of the present invention has been devised, which comprises a plurality of closing heads located inside a vacuum chamber, with a only rotating sluice in and out of cans, being intercalated in the means of transport of the chain of production of the cans as a loop perpendicularly arranged to said means of transport. The revolving lock or star adopts the form of a cylinder of reduced height, with lateral housings in a manner coinciding with the shape of the cans to be used, which rotates synchronously with the means of transport of the cans within a frame with a rectangular opening coinciding with the cross-section of the rotating lock, the hermetic closing being ensured by means of elastic closing plates interspersed between the rotating lock and the frame, which are adapted by pressure allowing the lock to rotate but preventing the entry of air into the Interior of the vacuum chamber. The access from the means of transport to the revolving lock has a ramp to raise the can when accessing the housings and would fit perfectly inside said housing, guaranteeing the tightness as it passes through the rotating lock.

El conjunto está soportado sobre una bancada que contiene el motor o motores necesarios para el movimiento y el cierre, los oportunos engranajes de transmisión, la bomba de vacío y el módulo de control del proceso. The assembly is supported on a bench containing the engine or motors necessary for movement and closing, the appropriate transmission gears, the vacuum pump and the process control module.

Esta máquina cerradora está especialmente concebida para ser capaz de utilizar tanto latas cilindricas como las no cilindricas, de formas irregulares. This closing machine is specially designed to be able to use both cylindrical and non-cylindrical cans, irregularly shaped.

Esta máquina cerradora en vacío de latas que se presenta aporta múltiples ventajas sobre los dispositivos disponibles en la actualidad siendo la más importante que utiliza una única esclusa, realizando la entrada de latas clinchadas y la salida de las latas ya cerradas por el mismo sitio. This vacuum closing machine for cans that is presented provides multiple advantages over the devices currently available, the most important being that it uses a single sluice, making the entrance of clinched cans and the exit of the cans already closed by the same site.

Otra importante ventaja es que la configuración de una única esclusa giratoria consigue mantener perfectamente el vacío en el interior de la cámara de vacío, minimizando enormemente las pérdidas de vacío. Otra ventaja de la presente invención es la posibilidad de utilizar tanto latas cilindricas como no cilindricas, de formas irregulares, que son ampliamente utilizadas para alimentos. Another important advantage is that the configuration of a single rotating lock manages to perfectly maintain the vacuum inside the vacuum chamber, greatly minimizing vacuum losses. Another advantage of the present invention is the possibility of using both cylindrical and non-cylindrical cans, of irregular shapes, which are widely used for food.

Otra de las más importantes ventajas a destacar es que, merced a realizar la entrada y salida por el mismo sitio, esta máquina cerradora puede integrarse fácilmente en cualquier cadena convencional de fabricación de conservas, intercalándose como un bucle perpendicularmente dispuesto, a diferencia de los dispositivos existentes que se intercalan linealmente en los medios de transporte, lo cual dificulta su integración en cadenas existentes. Another of the most important advantages to highlight is that, thanks to the entry and exit through the same site, this closing machine can be easily integrated into any conventional canning chain, being inserted as a perpendicularly arranged loop, unlike the devices existing that are interspersed linearly in the means of transport, which hinders their integration into existing chains.

Asimismo otra ventaja añadida es que esta máquina posibilita la realización de la mayor parte de las operaciones de enlatado, como el llenado o el posicionamiento y clinchado de las tapas sin necesidad de vacío, realizando únicamente el cierre en vacío, lo cual simplifica enormemente la instalación de producción de conservas, con el consiguiente ahorro económico en el proceso. Likewise, another added advantage is that this machine makes it possible to carry out most of the canning operations, such as filling or positioning and clinching of the lids without the need for a vacuum, performing only the vacuum closing, which greatly simplifies the installation of canning production, with the consequent economic savings in the process.

Otra ventaja añadida es que esta configuración de máquina posibilita un proceso de cierre en vacío con gran precisión y alta velocidad, además de minimizar el mantenimiento y las posibles averías. Another added advantage is that this machine configuration enables a vacuum closing process with high precision and high speed, as well as minimizing maintenance and possible breakdowns.
