  • Patent number: 11904626
    Abstract: An envelope sealing and flipping system can be incorporated into a mail inserter system to seal an envelope with a complete unbroken glue line and simultaneously flip the envelope face-up for downstream processing. The system includes a flip cage that receives an envelope and a moveable wetting brush that contacts the flap. The flip cage rotates, causing the flap to drag underneath the wetting brush, and realigning the envelope with a sealer nip which seals the envelope. The flip cage rotates continuously to receive, flip, and seal many envelopes.

    Abstract: A machine for closing and sealing cardboard boxes or other packaging cases with random sizes of cases presented. An input gate controls passage of cases onto at least one conveyor that moves the cases through the machine. An input positioning stage centers and squares the case. A measuring station performs a primary measurement of the width and height of the open case. A closing station and tape sealing station are adjusted to the primary case size measurement. The case closing station then closes the case. The side major flaps are closed using a major flap closer with crossed arms pivoted at separated pivot axes. The sealing station has a secondary or closed case measurement detector which more accurately adjusts the tape applicator height. Lateral support heads engage the sides of the case to prevent distortion while tape is applied.

    Abstract: An envelope closing mechanism with a deflector (11; 61) for urging a flap (6) of an envelope (3) from the transport path (20; 70); and a moistener (7) for moistening at least a portion of the flap (6) of an envelope (3). The deflector (11; 61) is movable between a position of rest on a side of the transport path (20; 70) located opposite the moistener, and a deflecting position on the other side of the transport path (20; 70) for urging the flap (6) of the envelope (3) against the moistener (7). If the deflector (11, 61) is in the deflecting position, it releases the transport path (20; 70) for transporting the envelope (3) along the deflector (11, 61). From a position in which the flap (6) of the envelope (3) extends between the moistener (7) and the deflector (11) in a deflecting position, the envelope (3), following the transport path (20; 70) is transported along the deflector (11) in the deflecting position with the fold leading.

    Abstract: Apparatus for packaging articles in clear clamshell packages includes a pair of parallel relatively narrow, laterally spaced apart conveyor belts that support there-between a package in open position by its opposing side peripheries. A stack of packages is supported in nested configuration adjacent the front end of the conveyor and de-nester mechanism withdraws packages there-from and places them on the conveyor. As the package is advanced a robotic arm picks and places articles of commerce and associated product information card in the package cavity. A rotating roller coated with UV-responsive adhesive coats raised male surfaces of the advancing package. Next an air knife sends a jet of air upwardly to cause the open package lid to rotate upwardly to cover the article-receiving portion. A driven roller presses the lid downwardly to fully close it and cause the adhesive coated surfaces to fully engage the corresponding grooves on the article-receiving portion.

    Abstract: A case sealer has a frame with a low friction conveyor upon which boxes are moved in series through three stages, each having an independent pair of spaced-apart, lateral conveyors that are linked together for inward and outward movement to accommodate the width of the box to be sealed. A first measuring stage measures the height, width and length of the box. A second flap folding stage has a floating head located over its lateral conveyors and is responsive to the height and width of the box and folds the box end and side flaps into a closed position. When a box enters the flap folding stage, the lateral conveyors in the measuring stage open to accept the next box, and based on the speed of the lateral conveyors and the measured length of the previous box, a gate allows the next box to enter the measuring stage as soon as the previous box has cleared the measuring stage.

The frames of the parallel and vertical-axis belts (C1, C2) which are designed to convey the boxes (B) with a vertical arrangement are supported cantilever-fashion by the base casings, via upturned portal structures (6). The operating stations of the machine are supported by the frames of the belts or by the base casings, such that the box conveying line is free at the bottom so as to allow better cleaning and better inspection. The middle module (2) inserts the product (V) into the boxes.
