Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a device for crushing municipalities, sightseeing spots and household waste garbage (bottles, cans, and other garbage) and separating the garbage and its storage bags such as vinyl.
[0002]
[Prior art]
In the conventional bag breaking and bag removing machine, the outside (frame body) of the device body is fixed, and the internal shaft and the blades of the device body rotate to break the bag and remove the bag.
[0003]
However, due to the rotation of the shaft and blades, large bags and long objects are caught on the blades or on the rotating blades. In some cases, and the rotating shaft could not move due to overload.
[0004]
Further, with the conventional bag breaking and bag removing machine, it is difficult to sieve the bottles and cans remaining in the bag after the bag is broken off from the bag.
[0005]
Also, a trommel for separating waste gypsum board and skin has been developed (for example, Patent Document 1).
[0006]
However, although it is easy to crush and crush waste gypsum board, it is difficult to perform impact crushing or crushing of bottles and cans in the above-mentioned trommel, and also to store bottles and cans and other garbage. It is difficult to perform separation from the storage bag to be performed using one separation trommel.
[0007]
[Patent Document 1]
JP-A-2002-254032 (FIG. 3)
[0008]
[Problems to be solved by the invention]
An object of the present invention is to crush or deform and shrink bottles, cans, and other wastes stored in a synthetic resin storage bag such as a plastic bag, and to safely separate the storage bag from these storage items.
[0009]
[Means for Solving the Problems]
In order to achieve the above object, the present invention firstly supports a rotating drum on four small receiving rollers loosely supported on a machine frame, and opens a concentric circular input port on a front end plate of the drum. The rear end surface of the drum is opened, a transport spiral is provided on the inner peripheral surface of the first half of the drum, and a bag-breaking blade is continuously provided along the inner peripheral edge of the spiral. A bottle, can, and other garbage / storage bag separation device in which a crushed garbage discharge through hole is formed to form a trommel, and a conveying stirring blade on the inner peripheral surface of the trommel is provided at intervals,
Secondly, the bottle, can, and other garbage / storage bag separation according to the first invention, wherein a crushed trash fall hopper is provided directly below the trommel, and a storage bag or other collection chute is provided immediately below the rear end surface. apparatus,
Third, the bottle, can, and other garbage / storage bag separation device according to the first or second invention, wherein the bag-breaking blade is provided in a zigzag shape on the inner peripheral edge of the spiral strip.
It is constituted by.
[0010]
BEST MODE FOR CARRYING OUT THE INVENTION
Two small receiving rollers 2, 2 and 2, 2, respectively, are provided at the front and rear of the machine frame 1 which is horizontally (FIG. 1) or inclined downward (for example, about 8 degrees to the right in FIG. 1). It freely supports the bearing bases 2 ', 2'.
[0011]
Support belts 17, 17 provided on the front and rear outer circumferences of the rotary drum 3 are supported on the four front and rear small receiving rollers 2, 2 and 2, respectively, and the drum 3 is freely movably supported on the machine frame 1.
[0012]
A gear 18 is formed on the outer periphery of the front end plate 4 of the drum 3, and an endless chain 19 meshing with the gear 18 is wound around a drive gear 21 provided on an output shaft of a drive motor 20 provided on the machine frame 1. By rotating the drive gear 21, the drum 3 can be rotated in the direction of arrow a in FIG.
[0013]
The front end plate 4 of the drum 3 is provided with an input port 5 which is concentric with the drum 3 and the rear end face 6 of the drum 3 is opened.
[0014]
The input port 5 is provided with a fixed input chute 22 for a synthetic resin film bag containing dust such as bottles and cans provided in the machine frame 1.
[0015]
A spiral strip 8 for conveying the film bag backward is welded 23 (FIG. 5A) to the inner peripheral surface 3 'of the first half of the drum 3 (FIGS. 5A and 5B). )
As shown in FIGS. 5 (a) and (b), a bolt 13 is provided along the inner peripheral edge 8 'of the spiral strip 8 so as to be substantially orthogonal to the rotation direction a and inclined in the direction opposite to the direction a. Are connected in a zigzag pattern.
[0016]
A large number of crushed trash discharge holes 11 (round holes, long holes, etc.) are neatly formed in the rear half disk 10 of the drum 3 to form a trommel 12, and along the inner peripheral surface of the rear half disk 10. The stirring blades 14 are provided at intervals of 90 degrees.
[0017]
The apparatus is provided with a falling hopper 15 for crushed garbage (bottles, cans, etc.) directly below the trommel 12 and a collection chute 16 for collecting miscellaneous substances mainly containing a storage bag immediately below the rear end face 6.
[0018]
As shown in FIG. 4, the transport stirring blade 14 bends the upper portion 14 'to the transport side.
[0019]
Therefore, a film storage bag containing the bottle, can and other trash is loaded into the drum 3 from the charging chute 22 and the drive motor 20 is started to rotate the drum 3 in the direction of arrow a. Let it.
[0020]
Due to the rotation, the storage bag moves from the front part to the rear part by the screwing of the conveying spiral strip 8, and repeatedly rises and falls under its own weight as the inner peripheral surface of the drum 3 rises. Is flattened by impact compression bending, contracted, and conveyed rearward.
[0021]
The storage bag is also repeatedly moved up and down by the bag-breaking blade 9, is broken by the blade 9, and is conveyed rearward.
[0022]
The bottles and cans conveyed to the rear reach the trommel 12 in the latter half of the drum 3, rise and fall by the rotation of the stirring blade 14, and are discharged out of the drum 3 through the crushed garbage discharge through hole 11, The crushed trash falls into the falling hopper 15, is discharged out of the machine, and is transported to a sorting machine via a discharge conveyor.
[0023]
Further, the broken storage bag or dust (for example, wood or rubber) which cannot be crushed, crushed or compressed and discharged from the through hole 11 is conveyed to the rear end of the drum 3 by the stirring blade 14 and opened. It falls from the rear end face 6 to the collecting chute 16 and is transferred to the next washing and sorting step by the conveyor.
[0024]
【The invention's effect】
Since the present invention is configured as described above, the bottles and cans and other broken materials and garbage are stored in the film accommodating bag and put into the rotating drum, and the bottles, cans and other broken materials are crushed in the first half of the rotating drum. In addition to breaking the bag, this can be discharged outside the machine from the latter half of the trommel and transported to the next sorting step,
Bags and other garbage that cannot be crushed and crushed can be broken or broken, and can be dropped from the rear end of the drum and transported to the next process, and bottles, cans, and film storage bags can be stored in large quantities. There is an effect that they can be separated and transferred to different next steps.
