A feeding device for a packaging machine, comprising:
- at least one channel (14) which, in use, contains a continuous array (S) of products (P), said channel (14) having a vertical lower end (26),
- a stationary base (30) located at the bottom of said channel (14), which supports said continuous array (S),
- at least one extractor element (32) movable in a vertical direction between a lowered position and a raised position and movable in a horizontal direction between a retracted position and an extracted position, wherein, in use, the extractor element (32) is cyclically movable between a retracted lowered position, a retracted raised position, an extracted raised position, and an extracted lowered position, wherein during the movement from the retracted raised position to the extracted raised position, the extractor element (32) extracts an individual product (P) or a stack of products (S1) from the bottom of said array (S),
- sensor means (48) arranged to measure the height of said individual product (P) or of said stack of products (S1), and
- an electronic control unit (50) programmed to adjust the stroke of the movement in the vertical direction of said extractor element (32) as a function of the measured height of said individual product (P) or of said stack of products (S1). |
