The second bag refuse remover 10 is provided with the first
The configuration is the same as that of the bag trash remover 7, and the description is omitted.

Further, the third bag trash remover 13 uses a pusher instead of an air nozzle of a sorting means described later in the first bag trash remover 7 and the pressing device for collecting the collected bottles in the collection section. The configuration is the same as that of the above-mentioned first bag refuse remover 7 except that it is carried into the transportation means without passing through.

The reason why the pusher is used in the third bag refuse remover 13 is that the bottle is heavier than the can,
This is because the recovery of the bottle is not obscured by the air jetting force of the air nozzle. Therefore, in the third bag trash remover 13, the pusher is configured to be able to reciprocate in the orthogonal direction on the first conveyor 71, and this pusher is used. The bottles are mechanically collected in the collection section. In the case where the bottle to be collected is formed in a cullet shape, the bottle may be configured to be conveyed from the collection unit to the transportation means via a press device.

FIG. 5 shows the structure of the fourth bag trash remover 14.

The fourth bag refuse remover 14 is configured to remove non-combustible refuse mixed in the combustible refuse and combustible refuse such as a lunch box from the combustible refuse conveyed by the main transport conveyer 30 into an iron can or the like. A metal sensor 31 disposed on both sides of a main transport conveyor 30 and a downstream side of the metal sensor 31 for removing bag litter conveyed in a state where non-combustible waste is stored in a bag. First pusher 32
And an ultrasonic sensor 33 provided on both sides of the main transport conveyor 30 downstream of the first pusher 32, and a second pusher 34 provided downstream of the ultrasonic sensor 33. .

The metal sensor 31 detects irons such as iron cans and aluminums such as aluminum cans that are put together with combustible waste or alone in a bag, and extends the first pusher 32 based on the detection result. Then, bag garbage containing iron cans, aluminum cans and the like is pushed out from the main transport conveyor 30 to the return conveyor 28. The return conveyor 28 is connected to the small bag breaking machine 4.

The ultrasonic sensor 33 detects bottles in the bag together with combustible waste or alone, and based on the detection result, extends the second pusher 34 to carry the bag-containing waste into the main transporter. It is extruded from the conveyor 30 to the return conveyor 28.

In the event that an iron can, an aluminum can, a bottle, or the like that is not contained in a bag is mixed in and conveyed by the main conveyor 30, the metal sensor 31 and the ultrasonic sensor 33 may be The first pusher 32 based on the detection result
And the second pusher 34 is operated to return the return conveyor 2
Extrude to 8.

Next, the operation of the refuse sorting apparatus configured as described above will be described.

The garbage discharged in the train is collected and stored in a large bag by an operator, and is put into the hopper 1 in a state of being collected in the large bag. The large bags put into the hopper 1 in this manner are sequentially discharged from the discharge port 1a and are carried into the large bag breaking machine 2 by the conveyor. The large bag breaking machine 2 breaks the large bag, takes out the refuse in the large bag, conveys it to the first sorting means 3, and conveys the debris of the large bag to the fourth bag trash removing machine 14.

In the first sorting means 3, newspapers, magazines, and invincibles are sorted out of the garbage taken out of the large bag manually or by an appropriate sorting device, and these newspapers, magazines, and invincibles are removed, and the rest is removed. It is transported to the small bag breaking machine 4.

The small bag breaking machine 4 breaks the small bag stored in the large bag, takes out the trash from the trash stored in the small bag, and conveys it to the second sorting means 5. In this way, the small bag breaking machine 4 breaks the small bag and takes out the garbage from the small bag,
Each subsequent sorting process can be performed efficiently and accurately.

The second sorting means 5 sorts combustible waste and non-burnable waste by wind power separation and sieving, and transports the burnable waste to the fourth bag waste removal machine 14 and transports the non-burnable waste to the magnetic separator 6 first. I do.

The magnetic separator 6 sorts out irons such as iron cans from the non-combustible waste and carries it into the first bag garbage collector 7, where the first bag garbage remover 7 sorts the iron based on the detection result of the detector 72. The naked iron can is collected by the collection unit 752 by the operation of the means 75,
After being conveyed to the iron can press 8 and subjected to compression processing by the iron can press 8, it is loaded on a truck or the like and transported.

The bagged iron cans not collected in the collection section 752 are transferred from the first conveyor 71 to the second conveyor 76.
And returned to the small bag breaking machine 4 by the second conveyor 76 again.

Here, the determination as to whether the iron can is a bare iron can or a bagged iron can contained in a bag is made by the first optical sensor of the detection device 72 when the iron can or the like passes through the detection device 72. The determination is made based on the detection results of the optical sensor 73 and the second optical sensor 74. That is,
If the second optical sensor 74 does not detect the passage of an iron can or the like by the first optical sensor 73, it is determined to be a bare iron can and this iron can is provided on the downstream side. When the air passes through the sorting means 75, air is injected from the air nozzle 751 and the naked iron can is collected by the collection unit 752 with this injection force.

When the second optical sensor 74 detects the passage of an iron can or the like by the first optical sensor 73 and detects the passage, the state is not a bare iron can, that is, the iron can is stored in a bag. It is determined that the iron can is in the bagged dust state, and when the iron can in the bagged state passes through the sorting means 75 provided on the downstream side, the first conveyer 71 does not eject air from the air nozzle 751. Conveyed as it is and the second conveyor 7
Carry in 6.

On the other hand, the remaining non-combustible waste that has passed through the magnetic separator 6 is conveyed to an aluminum separator 9 where the aluminum such as an aluminum can is sorted, and the aluminum is separated into a second bag dust remover 10. Bring in. In the second bag trash remover 10, just like the first bag trash remover 7, bare aluminum cans are collected, carried into the aluminum can press device 11, compressed, and then loaded on a truck or the like for transportation. In addition, the uncollected bagged aluminum cans are returned to the small bag breaking machine 4 by the second conveyor 76 again.

Further, the remaining incombustible waste that has passed through the aluminum sorter 9 is conveyed to a bottle sorter 12, where the bottles are sorted and carried into a third bag dust remover 13. In the third bag trash remover 13, only the bare bottles are collected, loaded on a truck or the like, and transported similarly to the first bag trash remover 7 and the second bag trash remover 10. The uncollected bottles in the bag state are returned to the small bag breaking machine 4 by the second conveyor 76 again.

As described above, the first to third bag trash removers 7, 1
Of iron bottles, aluminum cans, etc., sorted by each of the sorting machines 6, 9, 12 by 0, 13, among bottles, by removing bagged garbage in a bag, these iron cans, aluminum cans, etc. , Bag garbage that may contain combustible garbage with bottles,
In particular, iron cans, aluminum cans, aluminum cans, and other bottles can be reliably sorted without treating even the garbage that is tied by wrapping iron cans, aluminum cans, and bottles in plastic bags. The garbage is returned to the sachet / bag breaker 4 again to break the bag, and the non-combustible material such as an iron can in the sachet and the combustible material are separated and sorted again, whereby highly accurate sorting can be performed.

The remaining residue that has passed through the bottle sorter 12 is conveyed to a fourth bag trash remover 14.

The fourth bag trash removing machine 14 includes a bottle sorter 12
In addition to the residue from the above, the above-mentioned combustible waste and the remnants of large bags are carried in. In the fourth bag garbage collector 14, incombustible materials such as iron cans are put into bags together with combustible waste such as lunch boxes. Non-combustible waste such as bagged garbage, iron cans remaining in the remains of large bags, and non-combustible garbage such as iron cans mixed without being sorted out due to some kind of failure are first detected based on the detection of the metal sensor 31 and the ultrasonic sensor 33. The second pushers 32 and 34 are operated to return to the small bag breaking machine 4 via the return conveyor 28 again. Also,
The combustible waste that has passed through the fourth bag waste removal machine 14 is incinerator 1
And burned.

In this way, the fourth bag trash remover 14 removes non-burnable refuse or bag refuse mixed with non-burnable refuse,
By returning the bag refuse to the small bag breaking machine 4 and sorting again, it is possible to prevent incombustibles from being carried into the incinerator 15 and to perform sorting with high accuracy.

FIG. 6 shows a second embodiment of the waste sorting apparatus. The same components as those of the above-described garbage sorting apparatus are denoted by the same reference numerals, and description thereof will be omitted.

The garbage sorting apparatus carries the non-combustible garbage sorted by the second sorting means 5 into the fifth bag garbage remover 16, removes the bag garbage with the fifth bag garbage remover 16, and removes the removed bag. The refuse is returned to the small bag breaking machine 4.

The configuration of the fifth bag trash remover 16 is the same as that of the first
-Same as the third bag refuse remover.

The non-combustible waste from which the bag waste has been removed by the fifth bag waste remover 16 is sent to the magnetic separator 6, the aluminum separator 9, and the bottle separator 12, as in the above-described embodiment. In this example, since the non-combustible waste is sent to the magnetic separator 6, the aluminum separator 9, and the bottle separator 12 in a state where the bag waste is removed by the fifth bag separator 16, the magnetic separator 6, the aluminum separator 9. Although there are no first to third bag trash removers for removing bag trash from bottles such as iron cans and aluminum cans sorted by the bottle sorter 12, the first to third bags are similar to the above-described embodiment. A third bag refuse removing machine may be provided to return bag refuse to the small bag breaking machine 4,
This can further prevent the baggage from being mixed.

Further, in this example, of the combustible waste sorted by the second sorting means, only large combustible waste such as a lunch box or a magazine is carried into the fourth bag garbage collector 14, and light combustible materials such as paper and plastic bags are taken out. Combustible refuse and small combustible refuse such as butts and split chopsticks are configured to be directly carried into the incinerator 15 without being carried into the fourth bag refuse remover 14. This is for train garbage.
This takes into account the unique situation of train garbage, in which large combustible garbage such as lunch boxes and magazines are put in bags together with iron cans, etc., and are highly discarded as bag garbage. It should be noted that all the combustible waste may be carried into the fourth waste removal machine 14 to remove the bag waste, thereby further preventing the bag waste from being mixed with high accuracy.

FIG. 7 shows a third embodiment of the waste sorting apparatus.

The garbage sorting apparatus carries the bag trash removed by the fifth bag trash remover 16 into a mini bag breaking machine 17 and breaks the bag trash with the mini bag breaking machine 17. It returns to the second sorting means 5 again.

The mini bag breaking machine 17 removes bags of small bag garbage (for example, iron cans, aluminum cans or bottles wrapped in plastic bags and tied) which cannot be broken by the small bag breaking machine 4. It is configured to break the bag, and even if the bag is smaller than this, the bag can be surely broken and the contents taken out, and the sorting can be performed with higher accuracy.

FIG. 8 and FIG. 9 show the first, second, and third
Alternatively, another configuration of the fifth bag trash remover is shown.

For example, the first bag trash remover connected to the magnetic separator 6 is provided on the conveyor 20 for transporting iron cans and the like from the magnetic separator 6 in a direction perpendicular to the transport direction of the conveyor 20. A pair of left and right chains 21 and 21 arranged
And a hook 22 provided between the chains 21, 21. The drive motor 23 drives the chain 21 in a direction indicated by an arrow Q shown in FIG. The bag is hooked on the conveyor 22a and removed from the conveyor 20.

The height L of the hook 22 from the conveyor 20 to the tip 22a thereof is set to be slightly larger than the height L 'of the iron can or the like conveyed by the conveyor 20. It does not remove even iron cans that have been properly sorted.

The transfer surface of the transfer conveyor 20 is formed in a net shape, and an air blowing duct 25 is disposed below the transfer surface. Air is blown upward from the nozzle 26 of the air blowing duct 25 through the transfer surface. Thus, the bag dust is configured to be easily caught on the hook 22.

The bag refuse thus hooked on the hooks 22 is removed from the transport conveyer 20, dropped onto the return conveyor 28 via the hopper 27, and transported to the small bag breaker 4 by the return conveyor 28.

Reference numeral 29 in FIG. 8 denotes a conveyor for conveying iron cans and the like from which bag dust has been removed.

FIG. 10 shows still another configuration of the first, second, third or fifth bag trash remover.

This bag refuse remover is one in which the hook of the bag refuse remover shown in FIGS. 8 and 9 is a chuck type, and a chuck device 40 is openable and closable between a pair of left and right chains 21, 21. They are arranged at intervals.

The chuck device 40 is composed of a fixed arm 41 and a rotating arm 42. An opening / closing arm 43 is continuously provided at the upper end of the rotating arm 42.
The upper arm 3 slides on the guide surface 44 a of the guide rail 44 so that the pivot arm 42 pivots between the chuck position and the open position via the opening / closing arm 43.
