Method, barrel subunits and units, service installations and assembly structures for the fabrication of moldable products, particularly based on concrete

A molding cylinder comprising:

• a rotary body exhibiting an n-fold rotation axis running horizontally, wherein n is a natural number;
• a bearing for engaging the rotary body and for supporting the rotary body to rotate around the n-fold rotation axis;
• n attachment means attached to the rotary body and distributed uniformly around the rotary body such that the rotary body together with the n attachment means exhibits an n-fold symmetry axis;
• n molding means, each attached to a corresponding one of the n attachment means;
• n covers, wherein each of the n covers is attachable to a corresponding one of the molding means;
• a workstation positioned at the rotary body such that the rotary body is rotatable by more than 270.degree. and thereby each of the n attachment means is movable into a position to be sequentially engaged by the workstation;
• and
• driving means attached to the rotary body for moving the rotary body into n different positions such that in each position one of the n attachment means is engageable by the workstation and each of the n molding means is rotatable through more than 270.degree. caused by the position changing of the rotary body for each sequentially following one of the n attachment means to allow for sequential repositioning of each of the n molding means at the workstation position for additional processing.

A method for manufacturing moldable products implementing equipment and technological organization solutions, aiming to improve a concentration, automation and flexibility of a manufacturing process as well as a curing of molded material, comprising:

• forming a plurality of molding means into a rotary structure shaped as a modular rotary cylinder having at least two faces, rotatable by more than 270.degree.;
• setting a main workstation around the modular rotary cylinder;
• setting installation of utilities specific to the main workstation grouped together around the modular rotary cylinder;
• setting the modular rotary cylinder into a position in which a first molding means of the plurality of molding means is in a defined upper position;
• filling the first molding means with material to be molded;
• closing the first molding means filled with the material to be molded with a first cover of a plurality of covers;
• repeating operations of setting, filling and closing until all molding means of the plurality of molding means are set, filled and closed;
• adjusting elastic suspensions of said molding means for moldable transmission of vibrations, produced during compacting of the material to be molded, to all of the molding means filled with material to be molded;
• treating the material being completely enclosed in said molding means intensively with heat over a travel distance substantially equal to a rotation of the modular rotary cylinder up to 360.degree. and resulting in an enhanced neutralization of an expansion of gases occluded within the material to be molded and of leakage by evaporation of molecules of water which are indispensable for quality hydration;
• performing a total multi-axis hydration of molecules in the material to be molded due jointly to a change in inclination of the material to be molded during the 360.degree. rotation of the modular rotary cylinder and to the vibrations;
• resetting the modular rotary cylinder into the position in which the first molding means of the plurality of molding means is in the defined upper position;
• releasing the first molding means of the plurality of molding means;
• removing the first cover of the plurality of covers;
• evacuating cured products from the first molding means of the plurality of molding means;
• transporting the cured products outside of the modular rotary cylinder;
• cleaning and oiling the first molding means of the plurality of molding means;
• and
• repeating operations of releasing the molding means, removing the covers, evacuating and transporting the cured products, cleaning and oiling the molding means until all molding means of the plurality of molding means are cleaned and oiled by repetitively resetting the modular rotary cylinder such that each of the plurality of molding means is positioned in the defined upper position during the operations of releasing, evacuating, transporting, cleaning, and oiling.

A method for producing molded pieces comprising:

• mounting a rotor to a rotation axis, wherein the rotor is furnished on its periphery with a natural number of attachment means uniformly distributed around the periphery of the rotor;
• mounting a molding form to each of the natural number of attachment means;
• placing a first one of the molding means in a workstation position;
• filling the first one of the molding means with material to be molded;
• covering the first one of the molding means with a cover;
• changing the position of the rotor for a sequentially following one of the attachment means up to the natural number of the attachment means into the workstation position followed by the placing, the filling and the covering of additional molding means for each workstation position assumed;
• curing the molded material in each one of the molding means during the rotation of the rotary body through more than 270.degree. caused by the position changing of the rotary body for each sequentially following one of the attachment means up to the natural number of the attachment means;
• placing the first one of the molding means in the workstation position;
• removing the cover from the first one of the molding means and a resulting molded structure from the first one of the molding means;
• changing the position of the rotary body for a sequentially following one of the attachment means up to the natural number of the attachment means into the workstation position followed by the removing steps for each additional molding means for each workstation position assumed such that the molding means is rotated through more than 270.degree. caused by the position changing of the rotary body for each sequentially following one of the attachment means up to the natural number of the attachment means;
• placing the first one of the molding means in the workstation position;
• cleaning and oiling the first one of the molding means;
• and
• changing the position of the rotary body for a sequentially following one of the attachment means up to the natural number of the attachment means into the workstation position followed by the cleaning and oiling step for each additional molding means for each workstation position assumed such that the molding means is rotated through more than 270.degree. caused by the position changing of the rotary body for each sequentially following one of the attachment means up to the natural number of the attachment means.
