PROBLEM TO BE SOLVED: To reduce the number of structural equipment for miniaturization. SOLUTION: Two shafts 2, 3 inclined downward to the forward direction are arranged at a crosswise space in a housing 1. The shaft 2 on the left side and the shaft 3 on the right side are rotated counterclockwise and clockwise, respectively, in a front view by a rotation driving means. A chute is provided in the housing above its rear end between both shafts 2, 3 to supply a waste storage bag. A waste recovery part 6 and a bag fragment recovery part 7 are provided in the housing 1 under between the front tapered portions 2b, 3b of both shafts 2, 3 and outside of the crosswise direction of the tapered portions 2b, 3b, respectively. Spiral blades 8, 9 are provided on the outer peripheries of the rear cylindrical portions 2a, 3a of both shafts 2, 3, respectively. Plural pins 11 are provided on the outer peripheries of both tapered portions 2b, 3b. A scraper 19 is provided to remove bag fragments hooked on the pins 11 from the pins 11 and drop them into the bag fragment recovery part 7. Useful waste is dropped from both tapered portions 2b, 3b into the waste recovery part 6. |
