Abstract:
An automatic carton length measuring and sealing tape dispensing device, comprising:a length detector including an ultrasonic length measurement system for measuring a length of a carton to which sealing tape is to be applied from the sealing type dispensing device having the proper length to apply to the carton for sealing attachment thereto, the length detector being able to measure the length without contacting the carton by sensing a first distance to a calibration surface and a second distance to a near surface of the carton when the carton abuts the calibration surface and operable to generate signals representative, respectively, of the first and second distances; and a controller connected to receive from the length detector the signals representative of the first distance to the calibration surface and of the second distance to the near surface of the carton and responsive to the first and second distances to determine the length of the sealing tape to be dispensed and to thereby provide a control signal output; and a sealing tape dispenser connected to receive the control signal output to dispense the length of sealing tape in response thereto.
