ABSTRACT:
A sensor system for use with a taping head of a box sealing machine includes a tape dispensing sensor and an box presence sensor. The tape dispensing sensor is positioned along the tape guide path of the taping head for determining whether tape is being dispensed from the taping head and for providing a positive response if tape is being dispensed. The box presence sensor is positioned on the taping head for detecting movement of an element of the taping head that reacts to the box being moved along the taping head and for providing a positive response if a box is present. A control system is provided and is connected to the tape dispensing sensor and the object presence sensor for determining a potential error condition if only one of the tape dispensing sensor and the object presence sensor provides a positive response. Preferably, three sensors are utilized in the sensor system. One senses tape dispensing, another senses a box presence, and yet another senses tape supply left on the roll. Tape breakage, tape run-out and tape run-on error conditions are identified by this sensor system and produce electronic signals that control a fault signalling device, such as a warning light, and also preferably control the main power to the box sealing machine.
