Various embodiments of the present disclosure provide a case-handling system including movable flap openers positionable relative to a case and operable to fold the upper major flaps of the case outwardly before the upper minor flaps of the case are folded inwardly and closed.

Case-handling system with flap openers

Various embodiments of the present disclosure provide a random case sealer. The case sealer includes a top-head-actuating assembly configured to vary the speed of the top-head assembly when ascending (to make room for the case beneath the top-head assembly) and when descending onto the case (to engage the top surface of the case during sealing). This maximizes the speed of the top-head assembly while limiting overshoot (when ascending) and preventing damage to the case (when descending). In certain embodiments the case sealer includes a tape cartridge configured to limit the forces imparted onto the leading and top surfaces of the case during sealing. These features result in increased throughput as compared to prior art random case sealers without requiring stronger cases or more protective dunnage.

Random case sealer

Various embodiments of the present disclosure provide a random case sealer configured to interrupt the case-sealing process upon detecting an object between the top-head assembly and the top surface of the case.

Various embodiments of the present disclosure provide a random case sealer including a pneumatically-controlled top-head-actuating assembly configured to vary the speed of the top-head assembly when ascending (to make room for the case beneath the top-head assembly) and when descending onto the case (to engage the top surface of the case during sealing). The case sealer includes a pressure sensor that monitors the pressure of gas incoming from a gas source delivered to the top-head-actuating assembly via one or more valves. A controller controls the open level and/or the open time of the valves based on the pressure of the incoming gas to ensure the top-head-actuating assembly operates as desired regardless of whether the pressure of the incoming gas is equal to, below, or above a desired pressure. These features result in increased throughput compared to prior art random case sealers without requiring stronger cases or more protective dunnage.

Various embodiments of the present disclosure provide a box sealer including a first box measurer including a top flap engager configured to move downwardly from a disengaged position above a box at a box measuring position to an engaged position in which the top flap engager engages one or more of the four upright open top flaps of the box. The amount of movement of the top flap engager is partially used to determine the height of the box. The determined height is then used to position a combined flap closer and flap sealer at an appropriate position.

A cutting mechanism assembly for use with a tape cartridge includes a support arm having first and second opposing ends and adapted to be coupled to the tape cartridge. The cutting mechanism assembly also includes a mount for a biasing element. The mount is coupled to the support arm and the biasing element is configured to couple the mount to the tape cartridge. Further, the cutting mechanism assembly includes a support plate for a mechanism for reducing a biasing force from the biasing element. The support plate is coupled to the support arm and the mechanism is configured to couple the support plate to the tape cartridge.

Tape cartridge

An application roller arm assembly for use with a tape cartridge includes a support arm having first and second ends and adapted to be coupled to the tape cartridge. The application roller arm assembly also includes a coupling for a biasing element. The coupling is coupled to the support arm and the biasing element is configured to be coupled to the coupling and the tape cartridge. Further, the application roller arm assembly includes a mechanism for reducing a biasing force from the biasing element. The mechanism is configured to be coupled the support arm and the tape cartridge.

A quick change knife blade assembly, for use in conjunction with a tape roll dispensing cartridge assembly of a case sealing machine, comprises a knife blade mounted upon a knife blade mounting plate. A pin plate is fixedly connected to mounting pins passing through the knife blade, and springs are interposed between the pin plate and the mounting plate so as to normally bias the pin plate to a position at which the mounting pins prevent the removal of the knife blade from the mounting plate. When the pin plate is depressed against the biasing forces of the springs, the mounting pins are moved so as to permit the knife blade to be removed from the mounting plate.

A knife blade guard locking mechanism, for use in conjunction with the sealing tape application rollers of a tape cartridge assembly of a case sealing machine, is adapted to be operatively connected to a spring biasing mechanism of the sealing tape application rollers such that when the sealing tape application rollers are disposed at their inoperative positions, the knife blade guard locking mechanism is disposed at its locked position so as to effectively cover the knife blade in order to protect personnel from being accidentally cut. Conversely, when the sealing tape application rollers are disposed at their operative positions, the knife blade guard locking mechanism is automatically unlocked so as to permit the knife blade to be uncovered in order to perform its sealing tape cutting operation.

A system for mounting the front or rear sealing tape application roller of a carton or case sealing apparatus wherein the front or rear tape application roller is able to be quickly and easily replaced upon its roller shaft without the need for special tools. A spring-biased detent pin which is spring-biased between a radially outwardly position at which the detent pin so as to be engaged with and block removal of the roller from its roller shaft but which may be depressed radially inwardly so as to be disengaged from the roller and thereby permit the roller to be removed from its roller shaft.

Quick change tape application rollers within a carton or case sealing apparatus

A tape guide plate and finger plate assembly for the leading end portion of the carton or case sealing tape is provided in order to effectively prevent the leading end portion of the carton or case sealing tape from folding over upon itself whereby the adhesive material, disposed upon the front side surface portion of the sealing tape would effectively become stuck to itself and thereby foul further carton or case seal-ing operations. In addition, rollers are provided upon a finger plate so as to permit the sealing tape to be dispensed in a substantially frictionless or drag-free manner.
