PROBLEM TO BE SOLVED: To provide a bag breaking device that unseals a bag for packing a valuables such as refuse of resources and an inner bag containing bottles which is wrapped by the former bag. SOLUTION: This bag breaking device is made up of a pair of bag breaking wheels 20 arranged in close proximity to each other for unsealing a bag packing contents. Each of the bag breaking wheels 20 has a wheel 12 and a conically trapezoidal saucers 16 provided on a rotary shafts 6b which are slightly inclined with the rotary shafts 6a. In addition, first pointed head parts 3a protruding almost perpendicularly upward are provided at almost an equal interval on the peripheral edge of the wheel 12, and second pointed head parts 13 are arranged at an equal interval in the peripheral direction on the inner peripheral part of the wheel 12. Further, the protrusion angle of the second pointed head parts 13 is different from that of the first pointed head parts 3a, and a pressing mechanism 19 fixed to a trestle is arranged above the adjacent parts of the bag breaking wheels 20. Thus it is possible to positively unseal a bag packing valuable materials such as refuse of resources and an inner bag. |
