DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, one embodiment of the bag-breaking sorting apparatus of the second invention will be described with reference to the drawings. FIG. 1 is a front view showing an embodiment of a bag-breaking sorting apparatus of the second invention, and FIG.
3 is a sectional view taken along line AA of FIG. 3, FIG. 3 is a sectional view taken along line BB of FIG. 1, FIG. 4 is a sectional view taken along line CC of FIG. 1, and FIG. 5 is a sectional view taken along line DD of FIG. FIG. 6 is a schematic perspective view of the bag breaking machine of the first invention used in the bag breaking sorting apparatus of the second invention.

In FIGS. 1 to 6, reference numeral 1 denotes a cylindrical drum which is horizontally mounted on a roller of a driving means which will be described later and which rotates in one direction at a speed of about 20 rpm around a horizontal axis. The drum 1 is provided with an inlet 1A for dust that has been crushed by a bag crushing machine, which will be described later, in the central portion, and a heavy dust discharge port 2 for empty bottles, empty cans, metals, etc.
A light-weight dust outlet 3 such as a paper or vinyl bag is formed at the other end. The dust input port 1A is formed by cutting out the body of the drum 1. Reference numeral 4 denotes a plurality of plate-like heavy-weight dust transfer scrapers which are fixed to the inner peripheral surface of the drum 1 between the dust input port 1A and the heavy dust discharge port 2 so as to be parallel to each other. Reference numeral 5 denotes a plurality of plate-like members which are fixed in parallel to each other on the inner peripheral surface of the drum 1 between the dust input port 1A and the lightweight dust discharge port 3 while being inclined in the opposite direction to the heavy dust transfer scraper 4 and parallel to each other. It is a scraper for transporting lightweight garbage.

Reference numeral 6 is a drive means for rotating the drum 1, and an annular rail 7 fixed to the outer periphery of both ends of the drum 1 and the drum 1 is horizontally mounted via the rail 7.
It consists of a plurality of rollers 9 installed on the gantry 8, and one of the rollers 9 is rotationally driven by a motor (not shown). Therefore, the drum 1 mounted on the roller 9 is rotated in one direction about the horizontal axis thereof by the driving means 6. Reference numeral 10 is a blower for sending air into the drum 1 from one end of the drum 1 on the heavy dust discharge port 4 side. Reference numeral 11 denotes a cover attached around the dust input port 1A of the drum 1. The cover 11 closes the dust inlets 1A on both sides and the bottom of the drum 1, and is fixed on the pedestal 8 without contacting the outer peripheral surface of the drum 1. Reference numeral 12 denotes a hopper for throwing dust into the bag to be broken, which is attached to the upper portion of the cover 11.

Reference numeral 13 is a bag breaking machine of the first invention provided in the hopper 12. The bag breaking machine 13 includes a horizontal rotary shaft 14, a rotating means 15 for the rotary shaft 14, a plurality of discs 16 fixed in parallel to the rotary shaft 14 at intervals, and an edge portion of each disc 16. And a pair of cutouts 18A formed on both sides of the plurality of discs 16 and fixed in the hopper 12 so as to face the bag breaking blade 17 through which the bag breaking blade 17 passes. A semi-arcuate guide plate 19 fixed in parallel between the blade 18 and the notches 18A facing each other between the pair of receiving blades 18 with a width interval of the notch 18A and along the upper half edge of the disc 16. It consists of The rotating means 15 has a rotating shaft 14
It comprises a small pulley 20 fixed to one end thereof, a large pulley 21 fixed to the drum 1, and a chain 22 connecting the small pulley 20 and the large pulley 21. The rotating shaft 14 continuously rotates in one direction as the large pulley 21 rotates integrally with the drum 1. The bag-breaking blade 17 has such a length that its tip projects from between the guide plates 19. Thus, by the action of the rotary bag-breaking blade 17 and the receiving blade 18 whose tips protrude from between the guide plates 19, the bag or box filled with dust is broken without crushing empty bottles or empty cans of contents. On the other hand, the strings that bind used paper such as used newspapers
Waste paper is cut without being crushed.

According to the bag-breaking sorting apparatus of the present invention, bag-breaking and sorting are performed as follows. That is, when a bag or a box-filled empty bottle or can, or used paper such as old newspaper bound by a string is put into the hopper 12, the bag-breaking blade rotating by the rotating means 15 in the hopper 12. By 17, the bag or box is broken without crushing empty bottles and cans, while the string binding the waste paper is cut without crushing the waste paper. The various kinds of dust thus sacked are thrown into the drum 1 continuously rotating in one direction by the driving means 6 through the dust input port 1A of the drum 1 through the gap between the discs 16. It Out of various kinds of dust put in the drum 1, heavy items such as empty bottles and empty cans are transferred to the heavy dust discharge port 2 side by the heavy dust transfer scraper 4 against the wind by the blower 10, and then outside the drum 1. Is discharged to. On the other hand, lightweight materials such as waste paper and vinyl are transferred to the lightweight dust discharge port 3 side by the wind and light weight dust transfer scraper 5 by the blower 10 and discharged to the outside of the drum 1.

Although the bags are crushed and sorted in this manner, in order to ensure the crushing of the bags more reliably, as shown in FIGS. Just stretch the bag chain 23. In this case, the broken bag chain 23
Both ends are fixed to the discs 16 on both sides, the center part is inserted into the hole formed in the disc 16, and the length of the bag-breaking chain 23 is such that when the disc 16 rotates, the bag swells by the centrifugal force. Bag chain
The length of the top of 23 is adjusted so that it slightly projects from the tip of the crushing blade 17. By providing such a bag breaking chain 23, even if the bag is not caught by the crushing blade 17 and the bag cannot be broken smoothly, the rotating bag breaking chain 23 can surely break the bag.

[0013]

As described above, according to the present invention, the bag is reliably broken by the rotating bag-breaking blade, and the dust after the bag is thrown into the central portion of the rotating drum is
By the action of the scraper and the wind force, it is possible to surely sort by weight, which brings about a useful effect that it can greatly contribute to recycling of dust.
