The present invention relates to a helical coil dispenser (4) for vending machines, which dispenser comprises a frame (5), a plurality of helical coils (6) mounted on the frame (5) and a plurality of motors (15), each connected to a respective helical coil (6), to determine rotation of the helical coil (6) about a longitudinal axis (X) and moving forward of the goods (P) supported by the helical coil (6). The dispenser (4) further comprises adjusting means (18) interposed between each motor (15) and the frame (5), said adjusting means (18) enabling shifting of the motors (15) along a rear side (12) of the frame (5) perpendicular to the longitudinal axes (X) and locking of said motors (15) onto the frame (5), to allow installation of a different number of motors (15) and helical coils (6) and/or installation of helical coils (6) of different sizes.
