Abstract (en)

A method for detecting a hopper insertion state for a bag-filling packaging machine using photoelectric sensors 7 provided at an item supply step position. The photoelectric sensors 7 detect deformation of the bag mouth that occurs when the hopper 4 is inserted into the bag mouth, and a decision whether the insertion status of the hopper 4 in the bag mouth is good or bad is made based on the detection result of the photoelectric sensors 7. If the tip end of the descending hopper 4 catches the bag mouth or presses the bag mouth and folds it, the bag face is moved away from the detection part 9 (light passage route) of the sensors 7, so that light from the light-emitting part of the sensors 7 reaches a reflecting mirror 6 and reflected, and the reflected light is detected by the light-receiving part of the sensors 7.
