A recently granted patent (Publication Number: US11952159B2) discloses a case sealer comprising a base assembly, a top-head assembly, an actuator, sensors, and a tape cartridge. The controller of the case sealer is configured to receive signals from the sensors and control the actuator to raise the top-head assembly based on the detection of objects. The system is designed to ensure efficient sealing of cases by moving the top-head assembly in response to the presence of objects beneath it and before reaching the tape cartridge.

Furthermore, the case sealer includes additional sensors downstream of the main sensors, allowing for more precise control over the sealing process. The controller is programmed to manage the movement of the cutter arm and roller arm within the tape cartridge based on the signals received from these sensors. This innovative design enhances the functionality of the case sealer by ensuring proper sealing and tape application while optimizing the overall efficiency of the packaging process.
