    DEVICE WITH SIDE PUSHING DEVICE AND PROCEDURE FORTRANSFER FLEXIBLE BAGS FILLED WITH A LIQUID PRODUCT,SUSCEPTIBLE TO FLOW, HIGH VISCOSITY OR GRANULATED FROM AFIRST CONTAINER TO A SECOND CONTAINER SECTOR OF THE TECHNIQUE
    The present invention concerns an apparatus with a lateral pushing device and a method for transferring flexible bags filled with a liquid and / or solid product capable of flowing from a first container to a second container. Typically the flexible bags contain either a flowing material, such as for example crushed fruit pulp, a high viscosity material such as a fruit concentrate, or a granulated material, for example hot melt glue beads, and stored within a rigid container that facilitates its handling and storage and protects said bag from breakage, tearing, weathering, and other circumstances that could damage the stored product,
    knowing this container system as "bag in box". BACKGROUND OF THE INVENTION
    Patent application document P201531818 provides an apparatus with a side pusher and a method for transferring flexible bags filled with a liquid product or capable of flowing from a first container to a second container.
    With regard to the procedure, said document P2015311818 describes a procedure that includes the extraction of a flexible bag from the inside of a first container by means of the turning of the first container disposed in a turning holder and moved by a turning mechanism. The turning bracket comprises a susceptacle base, a susceptacle side wall connected to the susceptacle base and an upper susceptacle edge belonging to the susceptacle side wall. Said turning causes the extraction of the bag from inside said first container by gravity by means of a first movement. The extracted flexible bag is received by a conveyor comprising a receiving and delivery end, a conveyor chassis and a transport surface, with relative movement between


    transport surface and conveyor chassis. The conveyor supports the flexible bag. Next, a movement of the conveyor applies a second movement to the flexible bag by which the flexible bag is inserted into a second container.
    A drawback of the state-of-the-art procedure is that, because the product contained in the flexible bags is a flowing material, the disclosed stages are not in themselves sufficient to successfully carry out the transfer of the bag from a first container to a container. second container The method presented in the aforementioned document is neither realizable nor viable and has a very low reliability.
    With regard to the apparatus, document P2015311818 does not have mechanisms to solve the problems related to the step of introducing the flexible bag into the second container.
    Likewise, document P201531818 also presents a funnel installed in the apparatus for transferring flexible bags. The funnel pushes the flexible bags laterally. The purpose of said funnel is to direct the base of the flexible bag to the bottom of the container and position the opening element of the upper part of the bag in the upper opening of the container by adapting the morphology or shape of the flexible bag to the surface inside the funnel. The funnel comprises a static piece with respect to the transport surface.
    A drawback of said funnel is that because the product contained in the flexible bags has a tendency to flow, there are surfaces of the bag that will experience greater friction against the inner surface of the funnel than others and, as a result of which the funnel piece is a unique piece and in addition to a closed contour, this produces slight misalignments and turns that at the end of the introduction stage the funnel does not fulfill its purpose, since the base of the flexible bag is not at the base of the container and / or The opening element of the upper part of the bag is not adjacent to the upper opening of the container.
    Another drawback of the funnel is due to the fact that the funnel is a closed contour piece, and therefore, control over the inclination of the transport surface and / or the speed of the transport surface is very critical in relation to avoiding a momentary jam of the flexible bag in the funnel, which brings us back to the situation of the previous problem, that is, a misaligned flexible bag
    or turned. The closed funnel contour can also cause a jam


    permanent of the flexible bag in the funnel, which makes it impossible to transfer the bag, decreases the efficiency of the system and increases the possibility of breaking or tearing the flexible bag.
    That is why the apparatus of the present invention has a lateral pushing device 5 connected to the conveyor chassis. EXHIBITION OF THE INVENTION

    It also comprises a second additional tilting axis perpendicular to the transport surface of the conveyor and articulated connected to the movable member of the second thrust actuator and the intermediate thrust plate and which makes said intermediate plate swing with respect to the first additional tilting axis and which causes said intermediate plate to move the second foot support along the additional linear guide such that the movement of the mobile member of the second


    thrust actuator swings in a plane parallel to the conveyor transport surface thus moving the side between said rest position and said lateral thrust position.
    In another specific embodiment, the lateral pusher carriage has an additional tilting axis perpendicular to the transport surface of the conveyor and is connected to the second foot support and which articulates the second foot support in an articulated manner and a tilting thrust plate.
