By discharging the contents GR in the vicinity of the lower end of the descending area DA, it is possible to reduce damage to the contents GR. In FIG. 20, another content GR is detached from the bags G and dropped on the support member 44, and the second holding member 57 holds the content GR dropped on the support member 44. ing.

  FIG. 21 shows a state in which the bags G held in the first engagement portion 53 are separated from the first engagement portion 53 and discharged to the supply / discharge portion 20A (transfer device 150). The bags G transferred by the first engaging portion 53 are separated from the first engaging portion 53 by centrifugal force and own weight. Further, the removal unit 60 </ b> A performs a removal operation (see FIG. 13), whereby the bags G held in the first engagement portion 53 are removed from the first engagement portion 53. The contents GR held by the second holding member 57 are also discharged to the supply / discharge section 20A (transfer device 150) near the lower end of the descending area DA.

  FIG. 22 is different from the case described with reference to FIG. 21 in a state in which the bags G held by the first engaging portion 53 are held by the first engaging portion 53 without being separated from the first engaging portion 53. The rotating state is shown. The restricting portion 58 comes into contact with the bags G and pushes them near the outer edge of the rotation area RA of the first engaging portion 53, thereby facilitating the engagement of the bags G with the second holding portion 52. When the bags G are broken by the first engaging portion 53 and the second holding portion 52 a plurality of times, the bags G held by the first engaging portion 53 are detached and the supply / discharge portion 20A (transfer) It becomes easy to be discharged to the apparatus 150).

[Operation of removal unit]
Next, the operation of the removing unit 60A of the bag breaking separation processing apparatus 100A will be described with reference to FIG. FIG. 23 is a front sectional view showing the operation of the removing unit 60A. FIG. 23 shows a state in which the bags G held by the first engaging portion 53 are sandwiched and cut by the cutting portion 641 and the contact portion 67 of the removing member 64. Even when the bags G are entangled with the first engaging portion 53, the bags G can be cut by the cutting portion 641 and the contact portion 67, so the bags G are removed from the first engaging portion 53. Can do.
