Device for reproducing images or graphic patterns, in general, on surfaces and corresponding method

摘要

Device for reproducing images or graphic patterns, in general, on large surfaces, the device comprising: - a support frame (12) provided with at least a first guide (16) along a first direction (and) and of, at least, a second guide (24) along a second direction (x); - at least one printing system (14) movable with respect to said support frame (12); - at least first motor means (26) designed to move said at least one printing system (14) along said first direction (and) and at least a few second motor means (28) designed to move said printing system (14) along said second direction (x); - an optical display system (100) associated with said support frame (12) and capable of recognizing the position of an image portion already executed; - a control unit (40) for giving orders to said printing system (14), characterized in that - the optical display system (100) is capable of recognizing possible reference signs set at the stage in which said portion of the image, in order to allow the correct positioning of the device to execute the adjacent portion of the image to be executed next; - the control unit (40) is capable of dividing into a plurality of sub-portions an image or graphic pattern to be reproduced, to give orders to said printing system (14) so that it executes, in a first reproduction stage, a first of said sub-portions and one of said reference signs, to allow positioning of said support frame (12) using said reference signs for the execution of a second of said sub-portions.
