Automatic dispensing system for liquid samples

An automatic dispensing system for liquid samples comprising:

• at least one independently-driven hydraulic circuit, with various a plurality of canister reservoirs (6) with a lid (1) and pumps (50) which transfer paint to end reservoirs, wherein each of the canister reservoirs (6) has a pump (50), a tube (41) and a dispensing hose (42) which connects to the holes of a nozzle (8), under which there is positioned a paint reservoir and, in a front part of fairing, electric buttons are positioned to turn on and turn off and, also, an emergency button, an integrated electronic processing and communication device that receives electric power coming from a source and an electronic board (51) which manages a mechanism of a cup (47) and motors of each pump (50), precisely adjusting the quantity of fluid dosed and having a software residing in the board (51) which sends commands to the pumps (50), characterized in that the pumps (50) of each of the canister reservoirs (6) are of a progressive cavity type pump (50) and the tubes (41) are corrugated;
• the nozzle (8) having a mechanism prescribing a semicircular movement comprising a cup support (44), on which there are connected two straight joints of rear arms (12) and two straight joints of front rear arms (13), two right (11) and left (9) supports and a support cup (47), into which the canister (6) is fitted, comprising a sponge and a sealing ring (48) and a sponge cup (49);
• a mechanism for eccentrically stirring the canisters (6) comprising a plate with various cutouts (14), the movement of which is driven by a continuous current stirring motor (43) with a pawl (18) on its shaft that tangentially pushes a pin (15) making it rotate;
• the center of the bottom face of the canisters (6) having a hole with a thread where an inner tube (5) is vertically mounted having the same height as the canister (6) where a metal rod (7) is loosely mounted with a thread at the top end which is fastened onto a stirring blade (2);
• the electronic board (51) manages closing sensors of the cup mechanism (47) and provides input for the sensors;
• the software residing in the board (51) controls a man-machine interface (S1), a frontend (S2), a backend (S3), a calibration method (S4) of dispensing data and a communication means (S6) for sending to the control board (51).
