Abstract

The invention relates to a method of punching and stacking labels, implemented from the bottom of the web (1), unwound from the unwinder and guided by a photocell in steps, where the photocell controls the operation and setting of the web between the upper die set (5) having the punch (6) and the lower the die set (7), on which the table (8) forms an asymmetrical wedge (9), having a bottom indentation (10) and an upper indentation (11) filled with steel balls embedded in soft metal and ground, the thicker side of the wedge (9) contains the frame (12) in which the bearing (13) is mounted on the guide (14). The needle bearing (15) is set between the indentations (10, 16)) contained in the upper (9) and bottom (17) wedge, the bottom of which (18) cooperates with the needle bearing (19), and the wedge (17) has a frame (20), fixed on the pin (21) of the cam (22), driven from the gear (23), receiving the drive from the gear belt gear (24, 25), connected to the motor (26), equipped with the inverter (27), management of all processes is carried out by an electronic controller. Label ejection is carried out by an ejector having an upper plate (30) and a lower plate (31), the upper plate (30) having holes in which pistons (32) are fixed, mounted on piston rods (33), connected to the lower plate (31) ) the ejector, fixed on the basis of the ejector (34) through the guides (35, 36), with the plate (30, 31) connecting the springs (37, 38), while the ejector base (34) is connected with an articulated quadrilateral (39) with the motor ( 40) and that the lower base plate (41) of the housing, and at the same time the pistons (32) contain tubes (42) with holes and are connected by means of tongues (43) to the vacuum generating device.
