[0028]
Next, the operation of the bag sorting apparatus for bag garbage configured as described above will be described.
[0029]
The so-called bag garbage containing the garbage in the garbage bag is put into the bag breaking device 1 in this state, and is broken by the bag breaking device 1, and the garbage in the garbage bag is taken out.
[0030]
The taken-out waste is conveyed to a waste sorting device, and is sorted into non-burnable waste and combustible waste, and if necessary, from non-burnable waste into aluminum cans and iron cans.
[0031]
Then, the garbage bag from which the garbage has been taken out is carried out to the bag transporting conveyor 2 and dropped by the bag transporting conveyor 2 onto the support basket 41 of the bag sorting bag sorting apparatus.
[0032]
The garbage bag dropped on the support rod 41 in this way is supported across the left and right support rods 41 as shown in FIG.
[0033]
In this state, by extending the telescopic cylinder 62 and moving the pushing plate 61 to one end side of the support rod 41, first, the tip of the pushing plate 61 forcibly moves the garbage bag to one end side of the supporting rod 41. By this movement, the first fixed blade 51 tears the garbage bag. Subsequently, when the tip of the pushing plate 61 reaches one end of the support rod 41, the garbage bag moved while being torn is pushed and pushed between the pushing plate 61 and the fixing plate 41a for bagging. Accordingly, the garbage bag is further torn by the second fixed blade 52 and transferred to the outside of one end of the support rod 41 (see FIG. 5).
[0034]
Then, the garbage bag conveyed to the outside of one end of the support basket 41 is held between the holding rollers 71, and as shown in FIG. 6, the dust remaining in the garbage bag is further squeezed by the rotation of the holding roller 71. Then, it passes between the holding rollers 71 and is carried out to the lower bag collecting conveyor 72. The garbage bags carried out to the bag collecting conveyor 72 are conveyed to an incinerator or the like for incineration.
[0035]
In this manner, the garbage bag is torn with the first fixed blade 51, and is pushed into the fixing plate 41a for bag ironing at one end portion of the support rod 41. Since it is pulled between the holding rollers 71, even if a small residue remains in the garbage bag, only the garbage bag can be taken out in a state in which this residue is reliably removed, thereby improving the sorting accuracy. It is possible to prevent damage to the incinerator and the like due to the incombustible material remaining in the garbage bag.
[0036]
In addition, the residue taken out from the garbage bag as described above is carried into the residue transport conveyor 8 through the chute 81, and is transported to the waste sorting device by the residue transport conveyor 8.
[0037]
When the above-mentioned residue is removed from the garbage bag and only the garbage bag is taken out, the garbage bag may be caught by, for example, the second fixed blade 52 due to the pushing operation of the pushing plate 61.
[0038]
When the garbage bag is jammed in this way, the jammed bag is released by the bag clogging release means 9. Specifically, when it is determined that the garbage bag is clogged, the rack 98 is reciprocated by the cylinder 97, whereby the rotating arms 91 and 92 are rotated once, and the rotation arms 91 and 92 are moved between the support rods 41 by this rotation. And move the side of the support rod. Thereby, the garbage bag clogged in the one end part of the support rod 41 is moved to the other end side of the support rod 41, and the clogging of the garbage bag is released.
[0039]
Whether or not the garbage bag is clogged between the end portions of the support rod 41 is determined by measuring the operating state of the telescopic cylinder 62 for moving the push-in plate 61 with a timer and obtaining an operation end signal even after a predetermined time has elapsed. If not, it is determined that the garbage bag is clogged.
[0040]
