    MANUFACTURING PROCEDURE OF CEMENT MORTAR PANELS PRETENSED WITH A ROBOTIZED FILLING STAGE, AND INSTALLATION
    CORRESPONDENT
    DESCRIPTION
    Field of the invention
    The invention is in the field of fabrication of prestressed cement mortar panels.
    More specifically, the invention relates to a method of manufacturing prestressed cement mortar panels, of the type comprising a filling stage in which a cement mortar is transferred from a mortar mixer to a hopper, and said hopper pours said cement mortar by gravity on a mold.
    The invention also relates to an installation for the manufacture of prestressed cement mortar panels, of the type comprising:
    - a hopper, configured to pour cement mortar by gravity onto a panel mold placed under said hopper,
    - a mortar mixer, configured to prepare a cement mortar and transfer said cement mortar to said hopper.
    State of the art
    In the construction materials manufacturing sector, reinforced cement mortar panels, prestressed in two directions using prestressing rods, are known. Usually these types of panels are manufactured using molds that are circulated under a static hopper that pours mortar. The hopper is connected by a passageway to a mortar mixer. The mixer in turn is usually located under the silos that contain the different components of the mortar, in particular, cement, aggregates and additives.
    However, these types of solutions have several drawbacks. The most important is the difficulty of obtaining a constant precision in the filling of molds, both in the amount of mortar that is poured and in that this mortar is distributed evenly. Another problem is the risk of splashes or spills of unwanted mortar in the area of the installation. This affects both the general conditions of the equipment, and even the final result, in case those unwanted spills reach the molds. Also, if changes in the mortar mixture are required between two filling cycles, for example, in case of adding additives with different dyes, it is necessary to clean the entire mortar circuit, including mixer, hopper and ducts.
    Therefore, the problem arises of providing a form of mold filling that allows precision in filling, that minimizes the risks of unwanted spills and that facilitates the cleaning of the components.
    Description of the invention
    The purpose of the invention is to provide a method of manufacturing prestressed mortar panels of the type indicated at the beginning, which allows solving the problem set forth above.

    Another objective of the invention is to provide a corresponding installation that performs said procedure.
    This purpose is achieved through a manufacturing process of prestressed mortar panels of the type indicated at the beginning, characterized in that the procedure uses a robotic hopper handling device, and why the following actions are performed:
    - said robotic hopper handling device displaces said hopper until it is placed in a first area below a mortar outlet of said mixer,
    - a predetermined amount of cement mortar corresponding to an amount necessary to fill said mold is transferred from said mixer to said hopper placed in said first zone,
    - said robotic hopper handling device displaces said hopper until it is placed in a second area above said mold,
    - said robotic hopper handling device opens an outlet of said hopper placed in said second zone to allow the cement mortar to exit and pour into said mold the cement mortar contained in said hopper.
    This means that a channeled fluidic connection between the mixer and the hopper is not necessary, which minimizes the risks of unwanted spills and, in particular, that the base components of the unmixed mortar get to contaminate the molds. This also eliminates the need for duct cleaning. In addition, since a predetermined amount of mortar is accurately chosen in each filling, this allows for a predictable and precise filling. On the other hand, the use of a robotic device to handle the hopper allows a programmable implementation that can be easily and accurately adapted to different mold filling conditions and to different distributions of the installation components.
    On the basis of the invention defined in the main revindication, preferred embodiments are provided whose characteristics are set out in the dependent claims.
    Preferably, said robotic hopper handling device comprises first weighing means weighing said hopper, and the transfer of cement mortar from said mixer to said hopper is automatically interrupted when said first weighing means indicate that it has been transferred to said hopper. said predetermined amount of cement mortar. Which increases the accuracy and predictability in each of the mold fillings, by obtaining just the necessary amount of material.
    Preferably, said mortar mixer comprises a valve that is actuated to allow or block the passage of cement mortar through said mortar outlet of the mixer. This avoids splashes or unwanted spills. In a possible embodiment, this valve is actuated by the robotic hopper handling device, which is especially advantageous if the latter is in charge of measuring the amount of mortar poured from the mixer.
    In preferred embodiments, said robotic hopper handling device makes a movement of said hopper in said second area above said mold while said hopper pours said cement mortar onto said mold. Since the movements of the robotic hopper handling device can be precisely programmed, this form of pouring results in an increase in the homogeneity of the mortar inside the mold.
    Preferably, said robotic hopper handling device comprises second weighing means weighing the cement mortar contained in said hopper while said hopper pours said mortar onto said mold, and reports said measured weight to means of

    Brief description of the drawings
    The advantages and characteristics of the invention can be seen from the following description in which, without limitation with respect to the scope of the main revindication, a preferred embodiment of the invention is mentioned by mentioning the figures.
    Fig. 1 shows a perspective view of an installation according to the invention.
    Fig. 2 shows a detailed plan view of the installation with the hopper placed in a first zone under the mixer.
    Fig. 3 shows a detailed plan view of the installation with the hopper placed in a second area on the mold.
    In the figures, the arrows without reference indicate the movement of the components of the installation.
    Detailed description of an embodiment of the invention
    In the embodiment shown in the figures, the manufacturing installation comprises a hopper 1, attached to a robot that is part of a robotic handling device of hopper 3. In the example, said robotic handling device of hopper 3 is controlled and programmed through numerical control systems. For its part, the hopper 1 contains cement mortar that is poured by gravity onto a mold 6 provided with prestressed rods, for the manufacture of a cement mortar panel.
    The installation also comprises a mixer 2 that prepares a cement mortar from components. As can be seen in the figures, there is no channeled connection between the mixer 2 and the hopper 1. Instead, the operating device 3 moves said hopper 1 between a first zone 4 located under the mixer 2, and a second zone 5 located on the mold 6. Thus, to proceed with the transfer of mortar from the mixer 2 to the hopper 1, the robotic hopper handling device 3 places the hopper 1 in the first zone 4, under a mortar outlet provided in the mixer 2. In the example the installation comprises transfer control means which in turn comprise a valve that constitutes interruption means and opening means, so that it allows to open and close the mortar outlet of the mixer 2, first weighing means provided in the robotic hopper handling device 3, and a control processor programmed to control the transfer of

    mortar. Thus, in the exemplary embodiment, once the robotic hopper handling device 3 has placed the hopper 1 in the first zone 4, the processor orders the opening of the valve, thereby starting to transfer mortar from mixer 2 to hopper 1. The process continues until the first weighing means detect that the predetermined amount of mortar necessary to fill the mold 6 has been transferred and communicates it to the processor that gives the order to close the valve, interrupting asl the transfer of mortar from the mixer 2 to the hopper 1. Preferably, the hopper 1 is fixed at the end of a robot arm of the robotic handling device of hopper 3, and the first weighing means is an electronic weighing system disposed between said robot arm and said hopper 1.
    Fig. 2 shows this stage of the process, in which the hopper 1 is placed under the mixer. Being a plan view, some components have been marked with dashed lines in the figure to show that they are partially hidden by others. Fig. 2 also represents possible movements of the robotic handling device of hopper 3 by means of arrows drawn for this purpose.
    Once the hopper 1 contains the necessary mortar, the mold 6 is filled. In the example, the mold 6 is open and placed horizontally in the second zone 5. Preferably, the mold 6 remains immobile until it has finished Filling with the mortar. With the mold 6 in this position, the robotic hopper handling device 3 places said hopper 1 on the mold 6 in the second zone 5, opening an outlet of the hopper 1 to allow the mortar to exit.
    As shown in Fig. 3, in the example, the robotic hopper handling device 3 moves the hopper 1 horizontally along the mold 6 above it, so that the mortar is distributed evenly within the mold 6 until completely filled. Optionally, the robotic hopper handling device 3 also displaces the hopper 1 vertically.
    Once the pouring is finished, the mold can be closed and the mortar set to the stage to obtain the prestressed mortar panels.
