PROBLEM TO BE SOLVED: To provide a device and method for numerically precisely grasping inspecting the slippage from a desired position of the blanked part of a paper- made packaging body regardless of the form, size, number and place thereof. SOLUTION: This device for grasping and inspecting blanked part of a paper- made packaging body comprises a measurement system 1 having a signal generator for generating a signal, an exciter for giving a vibration to a paper-made packaging body according to the output of the signal generator, a non-contact type or contact type displacement sensor for measuring the displacement and acceleration of the paper-made packaging body, and FFT analyzer for FFT processing and comparing the output of the signal generator with the measurement output of the non-contact type or contact type displacement sensor to determine a transmission function; and an analyzing system 2 having a comparing means for comparing the determined transmission function with a basic data to judge the state of the blanked part of the paper-made packaging body. |
