A configuration in which the number of times of contact with the bag breaking cutter is increased from the loading position to the discharge section by using a lagging transport roll that conveys the sheet in the inclined direction, and a number of bag breaking cutters attached to the roll. The bag removing unit is characterized by being constituted by a separation mechanism by retention and agitation of the broken bag.

According to the first aspect of the present invention, there is provided a bag-breaking portion provided in a front stage, a bag-removing portion provided in a rear stage, and a bag is reliably and efficiently broken in a front stage and a bag-removal portion is left in a rear stage. In addition to the bag removal, the bag pieces and the contents are completely separated. In the bag breaking section, a transport means for breaking the garbage bag supplied from the hopper and transporting the garbage bag to the discharge section, and a bag breaking cutter for breaking the garbage bag in the transport process are provided. The means is constituted by a group of rolls arranged side by side in an inclined manner, and the rolls are rotated in the anti-meshing direction, and a moderately slow conveyance speed is set according to the inclination and the number of rotations. This makes it possible to make a contact with the bag. In order to maintain the above-mentioned slow conveyance speed, a projection may be provided obliquely on the roll surface. Next, the bag removing section that removes and separates the contents from the broken bag is a means that allows the garbage bag that has been broken into the bag removing section to stay for a long time, and the bag that has been broken during the retention period. A separation mechanism including a stirring means capable of controlling the posture of the garbage bag, such as upside down, left and right, and the like, allows the contents to be reliably separated from the broken pieces.
