Abstract
A vibrating device is incorporated in a packaging machine to vibrate packaging bags filled with articles. The vibrating device includes a tapping plate disposed below the bags, a servomotor having an output shaft, a selection unit selecting one of vibration patterns set according to sizes of the bags or types of the articles, an output unit delivering data of a rotation pattern of the output shaft, and a control unit controlling the output shaft according to the rotation pattern based on the delivered rotation data. When one vibration pattern is selected according to the size of the bag or the type of the articles, the control unit controls the output shaft according to the rotation pattern corresponding to the vibration pattern, so that the tapping plate connected via a link mechanism to the output shaft is vibrated up and down in the selected vibration pattern to vibrate the bag.
