Corrugated cardboard box stacking device in a corrugated cardboard box making machine

A corrugated cardboard box stacking device in a corrugated cardboard box making machine, comprising:

• a feed means for feeding manufactured and folded corrugated cardboard boxes one by one in the horizontal direction;
• a front portion support means for supporting the front portion of the corrugated cardboard box fed from the feed means at a predetermined position in the longitudinal direction;
• a pair of rotary screws arranged at right and left sides for stacking the corrugated cardboard boxes in a group from a lower to an upper portion in the area between the rotary screws, said rotary screws being arranged at intermediate position between the feed means and the front portion support means in the longitudinal direction for supporting a corrugated cardboard box fed from the feed means at its both sides to raise the corrugated cardboard box into a storing space by rotation;
• a gauge plate which comes in contact with the upper surface of the rear end of the uppermost box in the group of the corrugated cardboard boxes for regulating the number of corrugated cardboard boxes to be stacked in the corrugated cardboard box storing space, which is positioned above the support means and the rotary screws;
• a kicker which moves forward and backward along the under surface of the gauge plate and pushes out the uppermost corrugated card box to advance it a little ahead of the front edge of the gauge plate;
• a count means for counting the number of the corrugated cardboard boxes moved from the storing space to a box stacking space, which is positioned above and a little ahead of the storing space by the pushing action of the kicker and the lifting action of the rotary screws;
• a pusher bar for transporting a group of the corrugated cardboard boxes in the box storing space by moving them forward when the number of the corrugated cardboard boxes stacked from below in the storing space reached a predetermined number;
• and
• a discharge means for discharging the group of the stacked corrugated cardboard boxes conveyed by the pusher bar.
