Flaps closer apparatus
View Patent ↗A flaps closing apparatus for closing full flap boxes is provided. The apparatus includes a flaps closing assembly with a first brake mechanism and closing bars with a second brake mechanism. The first brake mechanism controls the vertical motion of the flaps closing assembly with respect to the flaps closing apparatus. The second brake mechanism holds the closing bars in an angled configuration and at a first predetermined vertical position permits the bars to pivot to a horizontal configuration. A flap sealing assembly includes a pair of compression plates positioned outside the flaps closing assembly. A compression plate actuating mechanism draws the compression plates inwardly to urge side flaps of the full flap box into contact with sides of the full flap box at a second predetermined vertical position. A vertical movement mechanism lowers and raises the apparatus.
1. A method of operating a flaps closing apparatus including a flaps closing assembly including one or more pairs of closing bars, a first brake mechanism in operative association with the flaps closing assembly and a second brake mechanism operatively associated with the one or more pairs of closing bars, a flaps sealing assembly including a pair of compression plates positioned outside said flaps closing assembly and a compression plate actuating mechanism connected to said pair of compression plates, and a vertical movement mechanism comprising:
providing a full flap box in an open condition with a pair of top flaps in a vertical position;
locking the first and second brakes;
lowering the flaps closing apparatus with the vertical movement mechanism;
contacting the pair of top flaps with the one or more pairs of closing bars being in an angled condition;
releasing the second brake to permit the closing bars to pivot to a horizontal position thereby urging the pair of top flaps closed;
contacting a top edge of the box with the pair of closing bars; releasing the first brake to permit the flaps closing assembly to float upwardly relative to the flaps sealing assembly;
activating the flaps sealing assembly to produce inward movement of the compression plates to urge end parts of the pair of top flaps toward sides of the box;
stopping the vertical movement mechanism at a predetermined position, and
contacting the sides of the box with the end parts of the top flaps to seal the box.
