A 20 liter one is used. In the trash box of the present invention, only paper dust or the like is compressed, and cans and bins are not compressed. A gate 30 that is opened and closed by a hinge 32 is provided inside the bulging portion 20 and forms an auxiliary storage portion 28 for paper dust or the like. The gate 30 is closed while the compression device is operating, and temporarily stores paper dust and the like that is input during that time. The compression device 50 includes a housing 12
Attached to the ceiling 14 of the.

FIG. 3 is a sectional view showing a state in which the compressing device 50 is compressing the paper dust (P) in the paper dust container 24, FIG. 4 is a sectional view in a standby state, and FIG. 5 is a bottom view of FIG. is there. The compression device 50 has a cylindrical airbag 52 that expands and contracts by supplying and discharging air, and a ring member 54 that is mounted inside the airbag 52 at appropriate intervals. The air bag 52 is made of an airtight sheet material, and the ring member 54 is made of a piano wire or the like to prevent the air bag from being crushed in the radial direction.

The upper edge 52a of the cylindrical air bag 52
Are sandwiched and fixed by the base plate 56 and the ring member 58. The base plate 56 is attached to the ceiling 14 of the housing by appropriate means such as bolts. The intake / exhaust pipe 5 is penetrated through the base plate 56 and the housing 14.
5 are provided. The lower edge portion 52b of the airbag 52 is sandwiched and fixed by the attachment plate 62 and the ring member 60.
Four guide bars 64 are planted in the mounting plate 60, and the guide bars 64 slidably support a compression plate 70 disposed below the mounting plate 62.

The guide bar 64 includes a mounting plate 62 and a compression plate 7.
A coil spring 65 is attached between 0, and the coil spring 65 biases the compression plate 70 in a direction away from the mounting plate 62. The mounting plate has a large number of needles 8 facing the compression plate.
0 is planted, and a hole 74 through which the needle 80 passes is formed in the compression plate 70. A rib 72 having an appropriate shape is attached to a surface of the compression plate 70 that presses the dust so as to reinforce the compression plate and effectively compress the dust. The reaction force of the compression is received by the ceiling 14 of the housing via the base plate 56.

An arm 90 is attached to the ceiling 14 of the housing, and the arm 90 supports a magnet 92. When the air in the airbag 52 is sucked out and the airbag 52 contracts, the compression plate 70 is pulled up and returns to the standby position. Magnet 92 attached to arm 90
Is the protrusion 6 of the ring member 60 fixed to the mounting plate 62.
Even when the negative pressure in the airbag 52 is reduced by adsorbing 0a, the compression device 50 is held at the standby position. The stopper 76 attached to the compression plate 70 hits the magnet 92 when the compression plate returns to the standby position, and reliably separates the compression plate 70 from the mounting plate 62.

By this action, the needle 80 is surely fixed to the compression plate 7
It is drawn inside 0. Air bag 5 of compression device 50
The air supply / discharge device 100 that supplies and discharges air into
For example, a blower 130 housed in a case 110 attached to the partition wall 6 is provided. This blower 130 is AC1
It is driven by a motor 120 of 00V (50 Hz / 60 Hz). The motor 120 has a maximum output of 450 W, for example. When the motor 120 rotates in the normal direction, the blower 130 draws in and pressurizes the outside air, and supplies the pressurized air into the airbag 52 of the compression device 50 through the pipe 150.

When air is supplied into the air bag 52 at the standby position, the air bag 52 inflates and the ring member 6
0 is separated from the magnet 92 and the compression plate 70 is pushed down. When the compression plate 70 comes into contact with the surface of the paper dust P stored in the dust container 24, the compression plate compresses the paper dust by the expansion force of the airbag. The maximum compression force is 1
It becomes 100 Kgf / m ² . The paper dust and the like generated in the railway vehicle is, for example, dust in which an empty glass of a lunch box is wrapped in a plastic bag. When the plastic bag is pressurized, the air inside is not discharged, and the plastic bag does not contract in a balloon state.

Therefore, in the compression device of the present invention, when the needle 80 is implanted in the mounting plate 62 and the compression plate 70 receives a resistance of a constant pressure, the needle 80 penetrates the compression plate 70 and is exposed. ,
It has a structure that sticks into the trash. The needle 80 breaks through the plastic bag mixed in the dust and discharges the air inside. This action causes the plastic bag to shrink,
Compaction and weight reduction of dust can be achieved. The compression rate is about half, and the real capacity is doubled.

This compression process is controlled by time. The timer switch 140 attached to the case 110 stops the motor when the motor 120 is rotated for a certain period of time, and then reversely rotates the motor. When the motor 120 rotates in the reverse direction, the blower 130 sucks the air in the airbag 52 and discharges it. The inside of the airbag 52 has a negative pressure and contracts. At this time, since the ring member 54 made of a piano wire is provided inside the airbag 52, the airbag 52 does not collapse in the radial direction but contracts only in the axial direction. The compression device returned to the standby position is attracted and held by the magnet 92.

The timer switch 140 stops the motor 120, which is the motor 120 rotating in the reverse direction for a certain period of time, to complete one cycle of dust compression. The time required for one cycle is, for example, about 20 seconds. While the compression device is operating, the display lamp 160 provided near the dust input port is turned on. The timer switch 140 repeats the above cycle at set time intervals.

Next, FIGS. 5 and 6 show another embodiment of the present invention. In the present embodiment, a vehicle-mounted pneumatic pressure source equipped in a vehicle is used as a device for supplying and discharging air that pressurizes and depressurizes an airbag. Since the structure of the trash box 10 is the same as that of the above-described embodiment, the same reference numerals are given and the description thereof will be omitted.

The air supply / exhaust device 200 includes a first pipe 220 and a second pipe 23 which communicate with an in-vehicle pneumatic pressure source 210.
Has zero. The first pipe 220 has a pressure reducing valve 222,
The pressure of the air from the vehicle-mounted pneumatic source is reduced to a pressure suitable for the dust box compression device 50. The solenoid valve 224 provided on the downstream side of the pressure reducing valve 222 connects the signal line 242 to the timer switch 240.
Are connected via. When the solenoid valve 224 opens in response to a command from the timer switch 240, pressurized air is supplied into the airbag 52 through the pipes 226 and 250, and the compression plate 70 compresses the paper dust P.

The second pipe 230 is connected to the ejector 234 via the solenoid valve 232. Ejector 23
Reference numeral 4 is for injecting a high-speed jet flow into the housing 237, and a negative pressure is generated in the housing 237. The jet flow of the ejector 237 is silenced by the silencer 236. When the two solenoid valves 232 and 235 connected to the timer switch 240 via the signal line 244 are opened, a negative pressure acts on the inside of the pipe 238, and this negative pressure reduces the inside of the airbag 52. Due to this action, the airbag 52 contracts and returns to the standby position. During operation of the compressor, the indicator lamp 160 lights up to inform the user of the address. The operation interval of the compression device is controlled by a timer switch.

[0021]

Industrial Applicability As described above, the present invention is a trash box which is mounted on a railway vehicle and stores paper trash such as lunch boxes, confectionery boxes, newspapers, magazines, etc., and is equipped with a compression device using an airbag. By doing so, it is possible to compress and reduce the amount of dust that is thrown in to about 50%. Therefore, the capacity for storing garbage is increased and the collection work is reduced. The work of compressing dust is automatically executed at regular time intervals. However, since the storage part exists even during the compression work, continuous charging is possible.

During the work, the pilot lamp is turned on to indicate to the user that the work is in progress, and safety can be secured. Further, even during the compression work, since the storage portion exists, continuous charging is possible. Also, since an airbag is used as an actuator that compresses the dust that has been thrown in,
Stable weight reduction performance can be obtained without applying excessive compression. Furthermore, since the airbag has a ring member that prevents the airbag from being crushed, the airbag always contracts into a constant shape and returns to the initial state. Since it operates by air intake and exhaust, the operation noise is quiet.
