Abstract: 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.

Abstract: Various embodiments of the present disclosure provide a random case sealer including a case lifter configured to lift a case out of engagement with a lower drive element 115 (such as a drive belt) of the case sealer as the case reaches a holding position beneath the top-head assembly 400 and, afterwards, to lower the case into engagement with the lower drive element once the top-head assembly has descended to within a designated distance of the top surface of the case. In certain of these embodiments, the case lifter includes a case blocker 215 positioned to stop the case from moving any further beneath the top-head assembly once it reaches the holding position.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.
