Abstract
A poker is provided to a packaging machine which has a former for bending a film into a tubular form and a chute for guiding articles to be packaged into a bag being made below. The poker includes a driver link which is driven to undergo a reciprocating rotary motion around a fixed axis and a generally L-shaped arm member disposed above and behind the former. A base part of the arm member is rotatably connected with a moving end part of the driver link such that the arm member can undergo a reciprocating rotary motion around a mobile axis of rotation which rotates around the stationary axis of rotation. A connecting mechanism is further provided to coordinate these two rotational motions such that the tip of the arm member distal from its mobile axis of rotation will move along a desired trajectory to reach a desired bottom center part of the chute which is likely to become clogged with the articles dropped thereinto. The connecting mechanism may be formed with a cam-following member attached to a part of the arm member and a cam plate with an elongated opening such that this cam-following member is constrained to move along an arcuate path determined by this elongated opening.
