Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for breaking bags, such as various containers, such as bottles, cans and plastic containers, which are contained in a plastic bag and discharged.

[0002]

2. Description of the Related Art As a conventional bag breaking device, for example, Japanese Utility Model Publication No. 2-30031 can be cited (see FIG. 5). In this apparatus, the municipal waste packed in a plastic bag, a cardboard box or the like is directly charged and stored in the hopper a.
The wastes stored in the hopper a are sequentially discharged from the discharge port f by the driving of the conveyor b. That is, the rotor d provided at the lower end of the dam plate c is rotated, and the claw e of the surrounding body is scratched by the rotation of the rotor d so that the rotor d is smoothly discharged from the discharge port f. Thereafter, this packaging waste is conveyed forward on the conveyor b, and is held by the restraining means g.
It is forcibly sent in the gap between. The waste reaching the inside of the gap is torn by the shearing action of the claw h attached to the surface of the conveyor b and the claw i protruding from the lower surface of the restraining means g as the conveyor b continues to move. When the waste material is broken and spills from the inside, the waste material reaches the end of the conveyor b, and is dropped and accumulated from the end portion of the conveyor b together with broken pieces of the packing material. The waste thus accumulated is automatically sorted manually or iron scraps and the like are automatically sorted by a magnet and temporarily stored in each stockyard.

[0003]

However, since the packed city waste is conveyed on the conveyor b and forcedly sent into the gap with the restraining means g to break the bag, the packed city waste is packed. Due to the clogging of the waste or the like, strong pressure may be applied in these gaps, and the reusable bottles in the waste may be damaged.

Further, even if the bag is broken and the waste is spilled from the inside, the waste is not sufficiently spread on the conveyor b after that, and there is a drawback that the waste is compressed and damaged in the narrowed gap as described above.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a bag-breaking apparatus for breaking bagging waste in which damage to reusable bottles is minimized. It is what

[0006]

In order to achieve the above-mentioned object, a bag-discharging device for bagging waste according to the present invention has a hopper rotated by a driving means and a supply port at the center fixed to the lower part of the hopper. The upper rotary table has a lower rotary table and a lower rotary table which is disposed below the upper rotary table at a predetermined interval to face each other so as to form a bag breaking chamber and which is rotated by driving means. In addition to providing linear blades that are oriented in the radial direction, spiral blades are provided on the upper surface of the lower rotary table, and bag breaking blades are provided on the facing surface side of each blade, and the upper and lower rotary tables are set in different directions. It is designed to rotate.

[0007]

The non-combustible waste packed in the bag falls on the lower rotary table from the charging port through the hopper rotated by the driving means. The non-combustible dust is broken by an upper rotary table that rotates together with the hopper and a lower rotary table that rotates by driving means in a direction different from that of the rotary table.
It enters the bag room, to move the 該破bag chamber. In this process, the bag is torn by the blades of the upper and lower blades. Therefore, the incombustible waste that is the content is scattered. The separated incombustible waste is spread out outward by the cooperative action of the linear blade and the spiral blade of the upper and lower rotary tables that rotate in different directions, and is reliably discharged. In addition, the contents after the bag is crushed are spread by the blades, so that the contents are not subjected to strong pressure so that the bottles are not damaged.

Embodiments of the present invention will be described below with reference to the accompanying drawings. 1 to 3, 1 is a waste conveyor, 3 is a cylindrical rotary hopper provided at the end of the conveyor 1 via a chute 2 and having a charging port 4 in the upper part and an opening 5 in the lower part. The hopper is provided with a large sprocket 6 and tires 7 on its outer periphery, and the tires 7 are supported by a plurality of vertical and horizontal support rollers 9 and 10 provided on a pedestal 8, and at the same time, a driving means provided on the pedestal 8, that is, a motor. A small sprocket 12 of the motor 11
The roller chain 13 and the large sprocket 6 rotate.

Reference numeral 14 denotes a disk-shaped upper rotary table fixed to the lower end of the hopper 3, which has a supply port 15 in the center and has a mountain-shaped gentle slope formed on the inner surface. Then, this rotary table rotates together with the hopper 3. Reference numeral 16 denotes a disk-shaped lower rotary table which is disposed below the upper rotary table 14 at a predetermined interval so as to face each other, and has a mountain-shaped gentle slope formed on the upper portion thereof and has an outer diameter larger than the outer diameter of the upper rotary table 14. It was done. The lower rotary table is provided with a large sprocket 17 and a ring-shaped tire 18 at the center of the lower part thereof. The tire 18 is supported by vertical and horizontal support rollers 20 and 21 provided on a machine base 19, and on the machine base 22. Drive means provided in the motor, that is, the motor 2
3, the motor 23 rotates via the small sprocket 24, the roller chain 25, and the large sprocket 17. And the upper and lower rotary tables 1 facing each other
The bag breaking chamber 26 formed by 4, 16 is narrowed from the inlet 27 side toward the outlet 28 side, and is slightly downward.

A plurality of blades 29 are provided upright on the lower surface of the upper rotary table 14, which are straight lines extending outward from the center of the upper rotary table 14. On the lower surface of each blade, bag breaking blades (claws) 30 are provided at appropriate intervals. It is a thing. A plurality of blades 31 are provided upright on the lower surface of the lower rotary table 16, and are formed in a spiral shape from the center to the outside, and bag breaking blades (claws) 32 are provided on the upper surface of each blade at appropriate intervals. It is a thing. The lower rotary table 16 is rotated in the direction opposite to the spiral direction of the blades 31, and the upper and lower rotary tables 14 and 16 are rotated in mutually different directions. 34
Is an annular path, 35 is a cover, 36 is a scraper, 37 is a non-reusable non-combustible waste discharge chute, and 38 is a level meter.

Next, the operation of the embodiment will be described. The packed waste is introduced into the rotary hopper from the upper introduction port 4 through the conveyor 1 and the chute 2. The amount of waste stored in the hopper 3 is detected by the level meter 38, and is maintained at an appropriate amount by controlling the operation of the conveyor 1. The waste in the hopper 3 falls on the lower rotary table 16 through the lower opening 5 and the supply port 15. The waste material on the lower rotary table 16 enters the crushing chamber 26 through the inlet 27 between the upper and lower rotary tables 14 and 16 which rotate in different directions by the respective driving means, and the respective vanes 29 facing each other.
By the cooperation of 31, it is forced to move little by little.

At this time, the blade breaking blades 30 of the blades 29, 31
The bag is torn by 32, and the non-combustible waste, which is the content, is released. Separated incombustible waste is the upper and lower rotary table 1
While spreading by the action of 4, 16 and blades 29, 31,
It is transported to the outside. That is, the non-combustible dust existing in an arbitrary mass formed between the adjacent vanes 29 of the upper rotary table 14 and the adjacent vanes 31 of the lower rotary table 16 rotates the non-combustible dust in the clockwise direction of the lower rotary table 16. On the other hand, while the upper rotary table 14 tries to carry it in the clockwise direction by the counterclockwise rotation of the upper rotary table 14, the combined action of the two causes the work to be carried almost outward. Moreover, the non-combustible dust in the mass spreads further because the mass spreads as the upper and lower rotary tables 14 and 16 rotate.
A large pressing force is not applied by the upper and lower rotary tables 14 and 16. The non-combustible waste transported as described above passes through the outlet 27 and the annular path 3 of the lower rotary table 16.
While riding on No. 4 and moving on the ring road 34, reusable items such as bottles and cans are manually collected from the inside. On the other hand, broken bottles that cannot be reused and other noncombustible dust and broken bags are scraped by the scraper 36 and collected in the storage box 37.

By narrowing the bag- breaking chamber 26 from the inlet 27 side toward the outlet 28 side, the chances of bag-breaking are increased, and by tilting it slightly downward, packed wastes and bulks are collected. This has the advantage of facilitating the movement of scrapped incombustible waste.
