Description

Máquina y método para envasar herméticamente productos pulverulentos, granulados, viscosos y similares .Machine and method to hermetically pack powdery, granulated, viscous and similar products.
OBJETO DE LA INVENCIÓN La presente invención tiene por objeto una máquina y un método para envasar herméticamente productos pulverulentos, granulados, viscosos y similares de cualquier tipo y naturaleza, en envases de configuración triangular, preferentemente isósceles . ANTECEDENTES DE LA INVENCIÓN Existen en el mercado muchos tipos de máquinas que efectúan el envasado hermético de diferentes productos en envases cuadrados o rectangulares, las cuales comprenden una bobina de material laminar para este tipo de envases, la cual a partir de un rodillo- -guia y mediante unas guias situadas a continuación proceden al doblado longitudinal central de dicho material laminar en forma de tira doblada, la cual en sucesivas etapas se la somete a una soldadura del borde inferior doblado y unas soldaduras verticales constitutivas de los envases sucesivos que quedan abiertos por el lado superior, cuyos envases son succionados por las caras opuestas para proceder a la apertura de su embocadura en la cual se procede al correspondiente llenado superiormente mediante un a modo de embudo o similar, y finalmente se procede a la correspondiente soldadura de dicha embocadura superior, de modo que queda el envase con el producto envasado en su interior. Las citadas máquinas conocidas utilizan unos envases normalmente cuadrados o rectangulares, y presentan el inconveniente de que requieren para su formación un consumo excesivo del citado material laminar.OBJECT OF THE INVENTION The object of the present invention is a machine and a method for hermetically packaging powder, granules, viscous and similar products of any kind and nature, in triangular shaped containers, preferably isosceles. BACKGROUND OF THE INVENTION There are many types of machines on the market that make the hermetic packaging of different products in square or rectangular containers, which comprise a coil of sheet material for this type of packaging, which from a roller-guide and by means of guides located below they proceed to the central longitudinal bending of said sheet material in the form of a folded strip, which in successive stages is subjected to a weld of the folded lower edge and vertical welds constituting the successive packages that are opened by the upper side, whose containers are suctioned by the opposite faces to proceed to the opening of their mouth in which the corresponding filling is carried out superiorly by way of a funnel or similar, and finally the corresponding welding of said upper mouth is proceeded , so that the container is left with the product packed inside. The aforementioned known machines use normally square or rectangular containers, and have the disadvantage that they require excessive consumption of said sheet material for their formation.
SUMARIO DE LA INVENCIÓN Los citados inconvenientes han sido eliminados mediante la presente invención que permite realizar los envases con el mínimo consumo del material laminar, a base de realizar envases triangulares, preferentemente isósceles, lo cual reporta una economía de costes y proporciona un envase triangular innovador de configuración preferentemente isósceles, que presenta una configuración en embudo que facilita el vaciado del mismo por el usuario en su utilización, y que la propietaria tiene protegido mediante el Modelo de Utilidad español N° U 200300692.

According to the present invention, the embodiment illustrated in dashed lines in Figure 2 with center of oscillation at the interior point -PI-, is the preferred embodiment. The oscillation of the folded strip -TM- of the packaging material and the filling tube -TL- of the product associated therewith oscillate in the said plane orthogonal to the guide roller, from the said guide roller -RG-, in which oscillation according to the aforementioned angle OI at each end thereof, the mouth of each successive container adopts the horizontal filling position, before proceeding to the corresponding sealing / cutting-climbing / sealing. During each oscillation in one direction or another of the folded strip, the container is filled by the filling tube, which can move in forward / reverse during filling, to facilitate the sealing / cutting / sealing of successive containers.

Said method allows the formation of the triangular packages, first filling, the inversion of the double strip, second filling and the individualization of the succession of triangular packages in the horizontal direction according to a preferably vertical plane. The advance of the triangular containers is carried out in two essentially perpendicular directions, by means of a turn -G-, both directions being contained in a preferably vertical plane, whose directions are essentially vertical before the turn and essentially horizontal after the turn, before the operation filling. The aforementioned method allows the formation of triangular packages only, regardless of their filling and / or individualization, or the filling and / or individualization of previously formed triangular packages. In the case of the double strip based on a sheet from a single coil, which is folded to form the double strip of two separate sheets, as illustrated in Figure 7, said folded sheet is cut longitudinally by the fold line using the opposing cutting elements -CO-, -CO- before practicing the formative V welds of the triangular packages.
