JPH09301503A - Contracted garbage container - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a contracted garbage container by simply and safely contracting and collect garbage. SOLUTION: A pair of belt bodies 3a are installed into a V shape so as to be faced to each other, and rotational driving devices are attached to shaft of the belt bodies 3a. The belt bodies and the rotational driving device are installed as one contracting unit 1 into a container so as to be vertically moved. Garbage input between the V-shaped belt bodies 3a is compressed, contracted and discharged under the belt bodies 3a. The discharged contracted garbage is sequentially deposited in the container, and the contracting unit 1 itself serves as a weight to help contraction of garbage.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a volume-reduced waste container for reducing and collecting waste.

[0002]

2. Description of the Related Art Conventional methods for reducing the volume of dust include compression, fine cutting, incineration, and melting. However, these methods require large-scale equipment, and have problems such as high heat and smoke emission. For small-sized ones, there is a cutting device called a shredder, but the fact is that it does not contribute much to reducing the volume of garbage.

[0003]

DISCLOSURE OF THE INVENTION The present invention solves the problems of the prior art, that is, large equipment, high heat, and generation of smoke, and is small, simple, safe, and highly effective in reducing the volume. Is provided.

[0004]

According to the present invention, in order to solve the above-mentioned problems, a pair of belt members are installed facing each other in a V shape, and a rotation driving device is attached to the shaft of the belt member. . These are installed as one volume reduction unit so that they can be moved up and down in the container. The dust introduced between the V-shaped belt bodies is compressed and reduced while being fed downward by the rotation of the belt bodies, and is discharged to the lower portion of the belt bodies. The discharged volume-reduced dust is successively accumulated in the container, and the volume-reduction unit itself serves as a weight to help reduce the volume of the dust.

[0005]

When dust is put between the belt bodies which are installed facing each other in a V shape, the dust is sent downward by the rotation of the belt body. Since the belt body has a V-shape whose interval becomes smaller as it goes downward, dust is also gradually compressed and reduced as it is sent downward, and is discharged from below the belt body. These are repeated every time garbage is thrown in,
Volume-reduced dust is successively accumulated at the discharge port provided below the belt body. When the discharge port is eventually filled with the volume-reduced dust and there is no space for discharge, the unit is pushed up as a reaction of the discharged force. If this continues for a while, the volume-reduced dust that has accumulated at the discharge outlet loses its balance and collapses. As a result, the volume-reducing unit that has lost its support falls due to its own weight. While repeating these steps, the volume of the input dust is reduced and collected.

[0006]

EXAMPLE An example of a volume-reduced waste container according to the present invention will be described below with reference to the drawings. FIG. 1 is an overall perspective view according to the present invention, FIG. 2 is a sectional view of the volume reducing unit in the XX direction, FIG. 3 is a sectional view of the volume reducing unit in the YY direction, and FIG. FIG. Let's take paper dust, which is very bulky, as an example. In FIG. 1, the volume reduction unit 1 is put in a garbage container 2. In this volume reducing unit, belt bodies 3a and 3b are installed facing each other in a V shape, and a motor 5 for rotation driving is attached to a shaft portion of the belt body. When you put garbage 13, garbage 1
3 enters between the belt bodies 3a and 3b in FIG. 2 and is fed downward by the rotation of the belt body. Since the belt bodies 3a and 3b are V-shaped, the distance between the belt bodies 3a and 3b becomes smaller as they go downward, and the dust 13 is gradually compressed and reduced as the dust 13 is sent downward. Is discharged. (State of FIG. 4) These are repeated every time dust is thrown in, and the volume-reduced dust is successively accumulated in the discharge port 4. When the discharge port 4 is eventually filled with volume-reduced dust and there is no space for discharge, the unit 1 is pushed up as a reaction of the discharged force.
(State of FIG. 4) If this continues for a while, the volume-reduced dust accumulated at the discharge port loses balance and collapses. (State of Figure 4)
As a result, the volume-reducing unit 1 that has lost its support falls due to its own weight. (State of FIG. 4) At this time, the volume reducing unit itself becomes a weight, and functions to prevent the volume-reduced dust from expanding again. While repeating these steps, the volume of the input dust is reduced and collected.

Reference numeral 6 in FIG. 2 is a spring which acts so as to attract the lower portions of the belt bodies 3a and 3b with an appropriate force. When a dust that is hard and is not compressed, such as pebbles, enters the thrown-in dust, the action of the spring 6 causes the lower portions of the belt bodies 3a and 3b to open a proper amount and is discharged without being clogged. By using an elastic body such as rubber for the belt bodies 3a and 3b, dust can be easily fed and the operation noise can be reduced. Further, even when a finger or the like is erroneously inserted, it is possible to prevent injury due to the action of the spring 6 described above. Reference numeral 7 in FIG. 2 is an auxiliary roller which functions to receive the deflection of the belt bodies 3a and 3b.

The separation plate 8 having the discharge port 4 is provided for the purpose of preventing the discharged volume-reduced dust from returning to the belt body by being caught again. By providing the belt bodies 3a and 3b with a plurality of grooves 9 and providing the separating plate 8 with the protrusions 8a so as to be inserted into the grooves 9, it is possible to more effectively prevent the volume-reduced dust from being caught.

Reference numeral 12 in FIG. 1 is a sensor for detecting that dust is thrown in, and 10 is a sensor for detecting that the volume-reduced dust is full. A guide roller 11 is attached to the outer circumference of the volume reducing unit to help the volume reducing unit move smoothly up and down in the waste container.

Depending on the type of dust to be thrown in, it is conceivable that the belt bodies 3a and 3b of the above-mentioned embodiment are not set in one set but in a plurality of sets, or in place of the belt body, a plurality of rollers are arranged side by side.

[0011]

As described above, according to the present invention, a large amount of equipment is not required, high heat and smoke are not generated, and the volume of dust can be reduced easily, safely and efficiently. be able to. According to experiments, the volume of paper towels used in the washroom is reduced to about 1/5 of that of ordinary dust. In addition, it is about 1 / in the case of compound waste such as paper cups, straws, and paper parcels that are found in hamburger shops and fast food restaurants.
The volume has been reduced to 4.

At present, the problem of garbage is a major theme, and one of them is garbage from fast food restaurants represented by hamburger shops, used paper towels from washrooms such as hotels and restaurants, or garbage from ordinary households. These volume reductions are a problem. However, it is difficult to sufficiently deal with the problem with the conventional technique as described above. The present invention is a great help in solving these problems.
