Field of the Invention The present invention relates to a waste compressor, and a waste compression plate which is disposed in a main body case and moves between the inside and outside of a waste collection container, and one of the waste compression plates is moved. The present invention relates to a dust compressor which is provided with a compression plate drive mechanism and is suitable for compressing dust discharged from general households.

[0002]

2. Description of the Related Art A waste compressor is disclosed, for example, in US Pat.
As disclosed in No. 0850, a refuse compression plate, which is held substantially horizontally in the container, is driven downward from above the refuse collection container arranged in the main body case to compress the refuse, and then the compression plate is Drive upward and open the upper part of the waste collection container to prepare for the input of waste. Further, when dust is thrown in, the dust compression plate is driven downward to compress the dust.

When the refuse collecting container is filled with a predetermined amount of refuse, the compressed refuse is taken out from the container and the empty container is placed in the main body case. In order to facilitate the processing of the refuse taken out from the container, a waste bag is usually placed in the container in an open state in advance.

[0004]

SUMMARY OF THE INVENTION In the above-mentioned waste compressor, since the vicinity of the input port where dust is likely to collect and the rear dust are compressed from above by the horizontal compression plate, the dust near the input port can be efficiently used. There is a problem that the amount of dust that can be input decreases because it cannot be compressed and dust accumulates near the input port.

Further, since the dust compressing plate rises upward in a horizontal state, the dust compressing plate narrows the vicinity of the loading port and interferes with dust loading.

Therefore, a first object of the present invention is to provide a dust compressor capable of efficiently dumping dust by compressing dust in the vicinity of an input port where dust easily collects.

A second object of the present invention is to provide a dust compressor in which the vicinity of the loading port is narrowed when the dust compression plate moves upward so as not to interfere with the loading of dust.

[0008]

According to a first aspect of the present invention, there is provided a main body case having a dust input port on an upper side, and one of the main body cases disposed below the main body case is opened to collect the dust thrown from the dust input port. A waste compression plate that moves up and down between the waste collection container and the inside and outside of this waste collection container to compress the waste in the waste collection container, and when you move this waste compression plate upwards While tilting the dust compression plate so that the part of the dust compression plate facing below the dust input port moves upwards, the dust compression plate moves downward when moving the dust compression plate. Inclining the waste compression plate so that the part of the waste compression plate facing the bottom of the waste input port will move downward in advance, and stop while the waste in the waste collection container is compressed To provide a compression plate drive mechanism One in which the.

With the above construction, when the dust compressing plate is moved downward, the part of the dust compressing plate facing below the dust input port is lowered first to compress the dust. Therefore, it is possible to efficiently compress the dust by compressing a large amount of dust peaks below the dust input port where dust is likely to accumulate and further pushing it backward. Furthermore, the waste compaction state is continued, and the original restoration of the waste is prevented.

The waste in the present invention includes not only waste such as packaging materials and kitchen waste discharged from ordinary households but also general compressible waste generated in various facilities such as offices and business establishments. Here, the waste collection container is a container having an opening at the upper part and having a capacity capable of collecting the dust put in from this opening, and is easily deformed by the pressure of the dust compressed by the descending compression plate. Alternatively, a container having strength that does not break is preferable, and the shape of the container may be a rectangular or circular horizontal cross section, but a container having an opening enlarged upward so as to receive a descending compression plate is preferable. The dust compression plate in the present invention preferably has a strength that does not easily deform or break by the pressure of dust compressed by the compression plate driving force.

According to a second aspect of the present invention, in the waste compressor according to the first aspect, the dust compression plate comprises a pair of dust compression plates, and when the dust compression plates are moved upward, the dust compression plates are placed on the dust compression plates. A compression plate inclination activating means for inclining each of the pair of dust compression plates obliquely is provided so that the dust accumulated in the above can be naturally dropped into the waste collection container. With the above configuration, the dust accumulated on the dust compression plate can be caused to fall naturally, and then the dust can be compressed.

The compression plate inclination activating means in the present invention is an angle at which at least one end of the compression plate is rotatably supported, and the compression plate is rotated around this axis so that dust accumulated from a substantially horizontal state naturally falls. Means to incline up to. The inclination angle is preferably at least 30 to 90 degrees from the horizontal.

According to a third aspect of the present invention, in the dust compressor according to the first or second aspect, the compression plate drive mechanism has an upper cross link that expands and contracts a stroke in the vertical direction in accordance with the motor drive, and an upper cross link. The upper end is connected to the lower end of the cross link, and the lower cross link consisting of the regulation side arm and the non-regulation side arm that attaches the dust compression plate to the lower end and the regulation side arm regulates the expansion and contraction of the vertical stroke. When the stroke of the upper cross link expands, the regulating side arm is regulated by the regulating link and the lower end of the non-regulating side arm is moved downward in advance to reduce the stroke of the upper cross link. At this time, the restricting arm is restricted by the auxiliary link so that the lower end of the non-restricting side arm is moved forward and upward. With the above configuration, when the dust compression plate is raised by the action of the regulation link, the lower end of the non-regulation side arm is advanced and moved upward, and when the dust compression plate is lowered, the lower end of the non-regulation side arm is preceded. The downward movement can be realized with a simple structure.

The cross link mechanism 7, which will be described later, is configured as shown in FIG. 7 and FIG. 8, and has an upper cross link with two arms 31 and 32 on the upper side and a lower cross link with two arms 33 and 34 on the lower side. In addition to these, and a restriction link by the short auxiliary arm 35, the upper end of the arm 31 (A in FIG. 7) is connected to the fixed support shaft portion 16 of the upper portion of the main body case 2 and The upper end (shown in FIG. 7B) is connected to a mover 17 that is screwed into the ball screw 13, and the arm 31 and the arm 32 are connected by a link shaft 36 so that they can move in the vertical direction.

The upper end of the lower cross-link arm 33 is connected to the lower end of the upper arm 32 by a link shaft 37, and the upper end of the arm 34 is connected to the lower end of the upper arm 31 by a link shaft 38. , One end of the short auxiliary arm 35 is connected to the link shaft 39 provided at a predetermined position from the lower end of the arm 33 of the lower cross link, and the other end of the short auxiliary arm 35 is connected to the link shaft 38 to provide a restriction link. ing.

As will be described later, when the dust compression plate 4 is moved downward from above by the above-mentioned restriction link, the part of the dust compression plate 4 facing the dust inlet 6a is inclined so as to precede and be located at the lower position. On the other hand, when the dust compressing plate 4 moves from the lower side to the upper side, the part of the dust compressing plate 4 facing the dust input port 6a precedes and is inclined so as to be in the upper position.

The dust compression plate 4 and the cross link mechanism 7
In addition, each member of each connection portion is configured to have a predetermined strength so as not to be deformed or damaged by a compression force when compressing dust.

On the other hand, on the inner surface of the main body case 2, as shown in FIG. 2, a plurality of activation pins 21 are provided as compression plate inclination activation means which come into contact with the dust compression plate 4 which moves up and down. As shown in FIG. 4, two activation pins 21 project above the opening 3a of the dust collection container 3 from the opposing inner surfaces so as to face each other at substantially equal intervals on substantially the same plane.

As shown in FIG. 5, each starting pin 21 is provided between a pin body 22 and a pedestal 24 that rotatably supports the pin body 22 on a support shaft 23, between one end of the pedestal 24 and the body of the pin body 22. It is mainly composed of a tension coil spring 25 stretched over. A stopper 26 that contacts the outer periphery of the pin body 22 and restricts rotation around the support shaft 23 is formed at an end portion that extends from the pedestal 24 to the inside of the body case 2.

With this structure, when the dust compressing plate 4 moves from the lower side to the upper side, the dust compressing plate 4 that comes into contact with the starting pin 21 whose rotation is restricted by the stopper 26 is
Each movable plate 4a resists the spring force of the coil spring 20.
Tilts around the support shaft 11. Thereby, the movable plate 4a
The dust on each movable plate 4a naturally falls with the inclination of. On the other hand, when the dust compression plate 4 moves from the upper side to the lower side, the activation pin 21 that comes into contact with the compression plate 4
Rotates downward around the support shaft 23 against the spring force of the coil spring 25 of the starting pin 21 (in the direction of the arrow in FIG. 5), and allows the dust compression plate 4 to pass in a substantially horizontal state.

When using the dust compressor 1 described above, FIG.
The loading port lid body 6 shown above is mounted in the main body case 2, and the dust thrown in through the loading port 6a is collected in the bottom portion 3b of the dust collecting container 3. At this time, the garbage compression plate 4
As shown in FIG. 9, the cross-link mechanism 7 is located at the bottom dead center inside the waste collection container 3 and holds the already-compressed waste in a compressed state. 4 is deposited on.

That is, in this case, as shown in the operation diagram of the cross link mechanism of FIG. 7, the arm 3 of the upper cross link is used.
The upper end B of 2 is at the right end, and the arm 31 and the arm 32 are
Becomes the horizontal state with the stroke expanded to the bottom,
The arm 33 regulated in the lower cross link is regulated by the regulation link by the short auxiliary arm 35 so that the lower end of the arm 34 precedes the lower end of the arm 33 and is located below the dust. The compression plate 4 is inclined to compress the dust.

Next, when a predetermined amount of dust is collected on the dust compression plate 4, the compression plate drive mechanism 5 is driven. As a result, the cross link mechanism 7 contracts and the dust compression plate 4 that has compressed the dust in the dust collection container 3 is pulled upward. That is, in this case, the upper end B of the arm 32 moves from the right end to the left end from the position shown in FIG. 7, the upper cross link arm 31 and the arm 32 are pulled up, and further, the lower cross link arm 33. Is restricted by the restriction link by the short auxiliary arm 35, and the position of the lower end of the arm 34 precedes the position of the lower end of the arm 33 and rises.

Therefore, in the state shown in FIG.
The portion C of the dust compressing plate 4 that compresses the dust in the dust collecting container 3 facing to is pulled up first, and the rear portion D is gradually pulled up. As a result, the empty volume of the dust collection container 3 at the portion facing the charging port 6a becomes large. Next, in the process in which the dust compression plate 4 moves from the lower side to the upper side, the dust compression plate 4 that comes into contact with the activation pin 21 that holds the protruding state.
The movable plate 4a tilts around the support shaft 11 against the spring force of the coil spring 20 of the support shaft 11. As a result, the dust accumulated on the dust compression plate 4 naturally falls into the dust collection container 3. In this case, particularly, the dust collected on the upper side of the dust compression plate 4 facing the charging port 6a where the dust is likely to be collected falls to the empty volume part of the waste collection container 3.

Further, in the process in which the dust compression plate 4 is pulled up by the cross link mechanism 7 from the state of FIG. 7, the arm 32 is pulled as the upper end B of the upper cross link arm 32 approaches from the right end to the left end, and the lower part of the arm 32 is pulled down. The cross link arm 33 is restricted by the restriction link by the short auxiliary arm 35, and the dust compression plate 4 moves upward while rotating in the counterclockwise direction in the drawing around the link shaft 39. Then, as shown in FIG. 8, when the upper end B of the upper cross-link arm 32 moves to the left end, the dust compression plate 4 comes to the position of the top dead center shown in FIG. In this process, as shown in FIG. 2, the dust compression plate 4 is rotated around the support shaft 11 by the spring force of the coil spring 20 and returned to the horizontal state.

When the dust compression plate 4 is pulled upward and positioned at the top dead center, the compression plate drive mechanism 5 immediately expands the stroke of the cross link mechanism 7 due to the cross link, and pushes the dust compression plate 4 downward. That is, this time, in the state of FIG. 8, the upper end B of the arm 32 moves from the left end to the right end in the drawing to move the upper arm 31 and the arm 32 of the upper cross link downward. In this case, the lower cross-link arm 33 is regulated by the regulation link by the short auxiliary arm 35, and is rotated around the link shaft 39 in the clockwise direction in the chain line in the figure so that the C of the dust compression plate 4 is rotated.
To drop the department in advance. In this process, the activation pin 21 that comes into contact with the dust compression plate 4 that cannot rotate upward around the support shaft 11 moves downward around the support shaft 23 against the spring force of the coil spring 25 of the activation pin 21. Rotation (arrow direction in Figure 5)
Then, the dust compression plate 4 is passed in a substantially horizontal state.

Further, when the dust compression plate 4 descends, that is, before the state shown in FIGS. 7 and 9 is reached, first,
The portion C of the dust compressing plate 4 is gradually pushed through the dust that is thrown in from the throwing port 6a and piles up like a mountain. Then, when the dust accumulated like a mountain is crushed by the C portion of the dust compression plate 4, the C portion of the dust compression plate 4 pushes the dust facing the lower part of the charging port 6a rearward. While compressing, the entire surface including the portion D of the dust compressing plate 4 is pressed. in this case,
The waste that has just fallen from the waste compression plate 4 and the waste that has already been compressed before that are compressed together. Garbage compression plate 4
As shown in FIG. 9, the compressed state of these dusts accumulated in the bottom portion 3b of the dust collection container 3 is continued.

Next, since the refuse compressor 1 continues the compressed state of the refuse until a predetermined amount of new refuse is collected on the refuse compression plate 4, the restoration of the refuse is prevented.

As described above, according to the first embodiment of the present invention, when moving the dust compressing plate 4 from the upper side to the lower side, the portion C of the dust compressing plate 4 facing the lower side of the dust introducing port 6a precedes. Then, the dust pile below the dust input port 6a where dust easily collects can be compressed in advance. Furthermore, the compressed dust can be pushed backward, and the dust can be efficiently compressed as a whole.

Further, since the compressed state is maintained when the dust compressing plate 4 is compressing the dust, and the dust compressing plate 4 is moved upward when a predetermined amount of dust is accumulated on the dust compressing plate 4. It is possible to prevent compressed waste from being restored to its original shape. Further, when the dust compressing plate 4 moves from the lower side to the upper side, the portion C of the dust compressing plate 4 opposite to the lower side of the dust throwing port 6a is moved upward so that the lower side of the dust throwing port 6a is moved. A large amount of dust can be thrown in by opening a large amount, and a pair of movable plates 4a of the dust compression plate 4
Is inclined so that the dust on the dust compression plate 4 can be naturally dropped.

FIG. 10 is a front sectional view showing a waste compressor according to a second embodiment of the present invention, in which the position of the dust input port in the first embodiment described with reference to FIGS. 1 to 9 is different. , A lid 10 having a dust inlet 10a
Is located on the right side surface of the main body case 2 and the insertion port 10a is enlarged.

According to this structure, when the dust compressing plate 4 shown in FIG. 10 is raised, the charging port 10a is largely opened, and further, the position of the portion C of the dust compressing plate 4 is raised. Since a large space is formed, a large amount of dust can be thrown in through the throwing port 10a, and dust can be thrown in easily. Then, the thrown-in dust is put into the throwing port 10a as shown in the drawing.
Piled up in a garbage collection container 3 close to.

In this case, first, as in the case of the first embodiment shown in FIGS. 1 to 9, first, the dust accumulated at the portion C of the dust compressing plate 4 is gradually compressed and compressed. When the refuse compression plate 4 rises upward while pushing the generated waste toward the back of the waste collection container 3, the portion C of the dust compression plate 4 is D as in the case described in FIGS. 7 and 8. To rise in front of the above-mentioned part to form a space in front of the charging port 10a. This makes it easier for the dust thrown in during standby and the dust thrown thereafter to fall into the dust collection container 3.

As described above, according to the second embodiment of the present invention, in addition to the effect of the first embodiment, since the opening of the charging port 10a is large, a large amount of dust can be further thrown in, and throwing in is easy.

[0041]

As described above, according to the invention of claim 1, when the dust compressing plate is moved downward, the part of the dust compressing plate facing the lower part of the dust input port is lowered first. Can be compressed to compress a large amount of dust piles below the dust input port where dust is likely to accumulate, and push it backwards to efficiently compress the dust, interrupting the dust compression state and preventing the original restoration of dust. it can.

According to the second aspect of the present invention, when the dust compression plate is moved upward, the compression plate is inclined obliquely to allow the dust accumulation on the dust compression plate to fall naturally, and then,
It is possible to shift to the compression process of garbage.
