The planar shape of the compression plate 29 is slightly smaller than the open planar shape of the garbage bag 18 so that it can enter the opened garbage bag 18 from above. 30 is a member for moving the compression plate 29, which is a piston 31a of the compression plate 1-moving cylinder 31;
The retaining pin 32 protrudes from the lower surface of the retaining pin 32.

The rear part of the compression plate 29 is connected to the engagement pin 32.
An engagement hole 33 into which is inserted is formed vertically through the engagement hole 33 .

In addition, as shown in FIG. 3, the state of attachment to the vehicle body is such that a storage chamber 9 for storing garbage bags, etc. is provided so as to protrude from the bottom of the vehicle body 34.
A storage chamber 9 for garbage bags, etc. is opened from an appropriate position and a garbage bag filled with a predetermined amount of garbage is taken out.

Next, the operation of this embodiment will be explained using the flowcharts of FIGS. 2 and 4.

As shown by the solid line in FIG. 2, when the bottom plate 6 is closed and the compression plate 29 is at position A, where it is retracted from the communication passage 10, garbage is transferred from the garbage inlet 3 to the garbage can 5 (v).

When the garbage is dumped into the bottom plate 6, the garbage accumulates on the bottom plate 6 (step ■). When a predetermined amount of garbage has accumulated in the trash can 5 (V+) (step ■), the infrared sensor 35 is activated, and the opening/closing cylinder 8 moves downward to open the bottom plate 6 as shown by the chain line in the figure. As a result, the garbage accumulated on the bottom plate 6 falls into the communication passage 10, is guided by the guide plate 23, and falls into the opened first garbage bag 18 (referred to as v2). After this garbage has fallen, the bottom plate 6 is closed to allow garbage to be thrown into the trash can 5 (v+) (step 2). When this bottom plate 6 is closed, the piston 31 of the cylinder 31 for moving the compression plate
A moves forward in the direction of arrow A, and moves the compression plate 29, which is engaged with the retaining pin 32, to the first position as shown by the chain line B in FIG.
is moved over the opening of the garbage bag 18 (V2) and stopped.

Next, the compression plate lifting cylinder 25 is operated downward, and the compression plate 29 together with the compression plate holding plate 27 is lowered into the first garbage bag 18 (VZi) as shown by the chain line position C, and is dropped and stored as described above. Compress the dust (step ■). When the compression plate 29 descends,
The engagement hole 33 is removed from the engagement pin 32, and the compression plate 29 is separated from the moving member 30.

When the predetermined compression action is completed, the compression plate lifting cylinder 25 moves upward, and the compression plate 29 is moved to the position B indicated by the chain line.
to rise and return. As a result of this return, the retaining hole 33 is fitted again to the engaging pin 32 that has been temporarily stopped at the forward movement position, and the compression plate 29 is connected to the moving member 30. When the compression plate 29 returns to the upward position in this manner, the compression plate moving cylinder 31 is operated backward to move the moving member 30 backward, and the compression plate 29 connected thereto is moved so that its tip 29a is connected to the communication passage section 10. It is moved back and returned to the solid line position A shown in the figure, where it does not protrude. When the amount of garbage in the trash can 5 (v+) reaches a predetermined amount again, the infrared sensor 35 is activated, the bottom plate 6 opens and the garbage falls into the first garbage bag t8 (vz), and is compressed again into the compression plate. 29 compresses the garbage that has fallen into the first garbage bag 18 (V,) by the same operation as described above. After this compression step, the amount of garbage in the first garbage bag 18 (Vl) is determined by an appropriate detection means using the amount of descent of the piston 26 or the number of times of descent, etc. (the amount of compressed garbage becomes elastic due to release of compression). For example, the height h of the garbage reaches a predetermined amount when the height h of the garbage reaches approximately 0.9h, which is the height of the first garbage bag t8 (vz). do (step~l)
. If the amount of garbage is not the predetermined amount, repeat the above steps from inputting the garbage, and if the amount of garbage reaches the predetermined amount, it is detected whether or not the garbage bag is the first garbage bag 18 (Vl) (step ■). . If the garbage bag is the first garbage bag 18 (ν2), the piston 14 of the garbage bag moving cylinder 13
moves backward in the direction of the arrow, moves the movable garbage bag holding plate 16 backward in the direction of the arrow via the moving member 12, and moves the first garbage bag 18 (Vl,) containing a predetermined amount of garbage to the first garbage bag. Move it to the position indicated by the chain line in Figure 2. At the same time as this movement, the second garbage bag 20 (with one end fixed to the fixed garbage bag holding plate 17)
The other end of v3) is pulled out by the movable garbage bag holding plate 16 and opened to receive garbage (step ■).
. Then, the process from inputting the garbage to compressing the garbage as described above is repeated. When the amount of garbage in the second garbage bag 20 (v,) reaches a predetermined amount, it is detected whether the garbage bag is the first garbage bag 18 (Vl) in the same way as described above (step 2).
At this time, a command is issued to the effect that the first trash bag 18 (Vz) is not present, and at the same time, the bottom plate 6 of the trash can 5 is locked in the closed state, and at the same time, a lamp or the like is used to notify the crew that the trash bag is full. Emit information (step ■)
.

As shown above, even after the garbage in the first garbage bag 18 (Vl) and the second garbage bag 20 (V3) reaches a predetermined amount, the garbage can 5 (
vl) continues to be ready to accept trash until the sensor 35 detects that the trash in the trash can 5 (Vl) has reached a predetermined amount.

Based on the above information, the crew member can remove the first and second garbage bags 1 while the bottom plate 6 of the garbage can 5 is in the closed garbage receiving state.
8. Take out the 20 and replace it with a new garbage bag.

Note that the operation of each mechanism is automatically controlled electrically using sensors, switches, and the like.

Furthermore, although the above-mentioned embodiment shows an example of use in a railway vehicle, the garbage disposal device of the present invention can be installed in a place where garbage disposal is required, such as a tourist north, a theater, a hall, and an event venue.

As mentioned above, the trash can S (Vl) and the first garbage bag t8 (
By providing Vz and the second garbage bag 20 (V3), for example, the amount of compressed garbage stored in the first and second garbage bags 18 and 20 is twice the amount of garbage in the trash can 5 (each Assuming that the number of times of compression is 2), and as mentioned above,
The first garbage bag t8 (vz) and the second garbage bag 20 (v3
) even after the garbage in the garbage bag 5 (ν1) reaches the predetermined amount.
Since garbage can continue to be accepted until the sensor 35 detects that the garbage in the trash bin 5(v,) has reached a predetermined amount, the maximum amount of garbage that can be stored in the garbage can is five times the amount that can be stored in the trash can 5(v,). , the garbage storage capacity is five times that of the conventional one having only the trash can 5.

[Effects of the Invention] According to the first invention, the garbage accumulated in the garbage can is dropped into a garbage container provided separately from the garbage can, and the garbage is compressed, so that the volume of the garbage can be reduced and stored. Therefore, the garbage storage capacity can be greatly improved. Therefore, when attached to a railway vehicle, for example, during long-distance operation, it is possible to prevent passengers from being unable to dispose of garbage due to the garbage can becoming full, as in the conventional method, and to allow crew members to dispose of garbage during operation. This eliminates the inconvenience of waste disposal, and also prevents floor stains and foul odors caused by garbage disposal. In addition, the trash can has a bottom plate that can be opened and closed, so by closing the bottom plate during garbage compaction work,
Even during garbage compaction work, passengers can safely open the lid and throw garbage into the trash can.

According to the second invention, even if the garbage container is installed almost directly under the trash can to reduce the size of the device, the compression plate is retracted outside the communication path when garbage falls, thereby preventing the garbage from falling. During compression, the dust container can be advanced directly above the garbage storage container to perform a good compression action.

According to the third invention, a plurality of garbage containers for compressing and storing garbage are prepared, and when a predetermined amount of garbage has accumulated in the first garbage container, the garbage can be moved to a second new empty garbage container. Automatically exchange,
Garbage can be compressed and stored in multiple garbage containers, further increasing the garbage storage capacity.
