MOVEABLE ROBOTISED CELL FOR THE PRODUCTION OF PIECES WITH A FRAME OR VERTICAL DUCTS PRE-INSTALLED INSIDE SAME AND OF ENCLOSURES, PRINTED ON SITE BY MEANS OF A MULTI-AXIS 3D PRINTING SYSTEM, AND OPERATING METHOD

摘要

The invention relates to a moveable robotised cell for the production of pieces with a frame or vertical ducts pre-installed inside same and of enclosures, printed on site by means of a multi-axis 3D printing system, comprising: a self-supporting structure, formed by three beams meeting at a zenithal hollow-shaft connection point which are radially disposed every 120° in a horizontal plane and respectively provided with a pair of lateral support plates, the peripheral ends of the beams being respectively provided with an elevation handle and respectively joined to a self-levelling telescopic post that rests on a base, the beams and their respective posts supporting power and control cables and hoses; a feed apparatus, formed by a semi-rigid external hose for carrying material, which is connected by means of a hose coupler to an extension tube with an attachment flange, which extension tube passes vertically through a hollow-shaft rotary connector and connects to a trifurcated rotary distributor, the three discharge openings thereof being connected to three flexible hoses for carrying material, which hoses are connected at the other end thereof to three interchangeable nozzles, wherein the hollow-shaft connector feeds a plurality of cables and hoses from three carriages of a circular-movement shaft to the zenithal hollow-shaft connection point; and a multi-axis actuator apparatus, which is formed by a circular-movement shaft, with three carriages that move three manipulator robots, the robots manipulating the three interchangeable nozzles, which have a shut-off valve and are connected to the three flexible hoses for carrying material.
