[0015]

BEST MODE FOR CARRYING OUT THE INVENTION The trash can with a trash compression function and the trash facility device incorporating the trash can according to the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a perspective view of an embodiment of a trash box facility device incorporating a trash box with a trash compression function according to the present invention, and FIGS. 2 to 4 show an embodiment of a trash box with a trash compression function according to the present invention. It is the front view, right side view, and top view of a form.

First, the structure and operation of the trash box with a trash compression function according to the present invention will be described below with reference to FIGS. 2 to 4, and thereafter, a trash box facility device incorporating such a trash box with a trash compression function will be described. The whole will be described.

As shown in FIGS. 2 to 4, the trash box with a trash compression function according to the present invention is hung from a frame 10 framed in the shape of a rectangular parallelepiped and an upper portion of the frame 10 and has a lower end portion. Telescopic link mechanism 2 that moves vertically
0, and dust holding means 50 held at the lower end of the expansion link mechanism.

The frame 10 is constructed by welding pipe materials having a rectangular cross section, and its external dimensions are such that it can be exactly accommodated in the storage space in the trash can facilities installed in Shinkansen vehicles and fast food stores. It is said that Then, in the lower inside of the frame 10, the waste container 6
The size is set so that 0 can fit in completely. Since the dust container 60 is deformed so as to bulge outward when compressed by the expandable link mechanism 20, it is preferable to fix the removable reinforcing plate 12 to the front surface side thereof. The pipe material 14 is arranged in the central longitudinal direction on the back side of the frame 10 to suppress the deformation of the dust container 60.

The telescopic link mechanism 20 is roughly composed of a drive unit 30 housed in the upper portion of the frame 10 and a link unit 40 driven by the drive unit 30.
The drive unit 30 is mounted on a plate member 31 fixed to the top of the frame 10.

In the illustrated and preferred embodiment, the drive portion 30 is operatively connected to a feed screw 32, which is rotatably supported at both ends and has a spiral thread on its outer peripheral surface. The motor 34 and a sliding member 36 that is screwed into the feed screw 32 and reciprocates in the axial direction of the feed screw are included. The sliding member 36 is connected and held to a bearing block 38b that performs a precision linear reciprocating motion along a track 38a fixed to the plate member 31. Of course, other mechanisms for reciprocating the sliding member 36, such as a ball screw mechanism, can be used.

The feed screw 32 and the motor 34 are connected to the pulley 3
2a, 34a and a belt 33 hung between them
Drivenly connected by. The pulley 34a attached to the rotating shaft of the motor 34 has a built-in electromagnetic clutch, and the pulley 32a attached to the feed screw 32 has a torque absorber built therein. The end of the feed screw 32 is further provided with a helical gear 35.
a is fixed, and a helical gear 35b that meshes with the helical gear 35a is rotatably attached to a support member 31a that is suspended and fixed from the plate member 31.

At the other end of the helical gear 35b, an emergency manual handle 39, which is drawn with a chain line in FIG. 4, can be detachably attached to rotate the feed screw 32 manually. At this time, the feed screw 32 and the motor 34 are drivingly separated by an electromagnetic clutch built in the pulley 34a, whereby the rotation of the manual handle 39 is lightened.

When the retractable link mechanism 20 sufficiently compresses the dust in the dust container 60 so that it cannot be further compressed, the torque absorber built in the pulley 32a works to prevent excessive torque. The transmission from the motor 34 to the feed screw 32 is prevented.

The link portion 40 includes two X members which are rotatably intersected with each other about a pair of link members 42 having the same length.
2 are hinged to each other in the vertical direction, and are doubled in the front-back direction in FIG. One of the upper ends of the pair of link members 42 located at the upper end of the link portion 40 is hinged to the support member 31b that is suspended and fixed from the plate member 31 fixed to the frame 10, and the link member 42 is also provided.
The other one is hinged to the sliding member 36.

As described above, the sliding member 36 is the motor 34.
The rotation of the feed screw 32 by driving the
It is adapted to reciprocate in the axial direction of 2. Therefore,
Since the upper end of one link member 42 located at the upper end of the link part 40 is hinged to the support member 31b and stands still at one point, the upper end of the other link member 42 moves horizontally along the feed screw 32. The link portion 40 extends as shown by the solid line in FIG. 2 or contracts as shown by the chain double-dashed line.

Although the position of the supporting member 31b and the stroke of the sliding member 36 differ depending on the length of the link member 42 and the like, the link portion 40 is extended as shown by the solid line in FIG.
That is, when the lower surface of the dust pressing means 50 moves to a height approximately half the height of the dust container 60, the crossing position 44 of the lower X-shaped links is located at the center of the dust container 60 in the width direction. It is preferable to set. As a result, the lower surface of the dust holding means 50 exerts the largest pressing force on the dust container 6.
It can be provided to the waste in the waste container 60 when it has moved to a height of approximately 1/2 of the height of 0.

A dust holding means 50 is attached to the lower ends of the pair of link members 42 located at the lower ends of the lower X-shaped links. The lower end side of the lower X-shaped link also opens and closes in the width direction of the dust container 60 as the link portion 40 expands and contracts similarly to the upper end portions of the pair of link members 42 located at the upper ends of the upper X-shaped links. Therefore, one of the lower ends of the pair of link members 42 is hinged to the dust holding means 50, and the other is connected via the cam follower 54 movable along the grooved guide member 51 fixed to the upper surface of the dust holding means 50. Join.

In the illustrated preferred embodiment, two X-shaped links are connected in the vertical direction, but of course, one X-link or three or more X-links may be connected. Since the number of X-shaped links in the vertical direction is related to the vertical stroke of the lower end of the telescopic link mechanism, the number of X-shaped links is increased when a long stroke is required.

In the illustrated preferred embodiment,
Limit switch L for detecting the extension state (downward end detection) and contraction state (upward end detection) of the telescopic link mechanism 20.
1, L2 are arranged in association with the linear guide device 38.

Referring to FIG. 5, there is shown a preferred embodiment of the dust holding means 50 attached to the lower end of the telescopic link mechanism 20.

The one shown in FIG. 5 (a) is formed by bending a plate-shaped member and has the same cross-sectional shape in the width direction of the dust container 60. The compression plate 52 has a V-shaped bending protrusion 52 that projects downward in the central portion.
a, and inwardly inclined surfaces 52b, 52b formed along both side edges and pressing dust inwardly. The protrusion 52a is a lunch box in the garbage container 60, a paper cup,
Makes it easy to fold and compress empty containers such as cans. On the other hand, the inwardly inclined surfaces 52b provided on both side edges of the compression plate 52 play a role of bringing the dust in the dust container 60 inward during compression, and prevent the compression force from being dispersed outside the dust container. Thereby, the bulge of the garbage container 60 can also be reduced.

The dust holding means shown in FIG. 5B is
A pair of rod-shaped rods 54, 54. The rod 54 is
It is supported so as to connect the lower ends of the X-shaped links that are doubly arranged in the front-rear direction. The rod 54 is the compression plate 5 described above.
Like the second protrusion 52a, the dust is easily folded and compressed. Needless to say, various structures other than the illustrated one can be adopted as the dust holding means.

Referring again to FIG. 1, there is shown a trash can facility device installed near the entrance of a Shinkansen vehicle. In this trash box facility device, a front door 70 having a lid 74 installed at a trash insertion port 72 is hingedly attached to the wall of the vehicle. A storage space 76 is provided inside the front door 70, and the trash can with a trash compression function according to the present invention shown in FIGS. It should be noted that in FIG. 1, the frame 10 is omitted for the sake of clarity. A trash container 60 is attached to the trash box with a trash compression function so that the trash can 60 can be taken in and out.

In the illustrated preferred embodiment, a key device 76 is provided that is controlled so that the lid 74 of the front door 70 does not open except when the retractable link mechanism 20 of the trash box with a dust compressing function is contracted. Has been. This is for the safety of users of the trash facility equipment. The key device 76 is also provided with a limit switch L5 for confirming that the key is open.

Further, the operation of compressing dust in the dustbin facility device according to the present invention is basically performed by a crew member in the case of a Shinkansen vehicle and a store clerk in a fast food restaurant. For the safety of these operators, limit switches L3 and L4 can be provided at the predetermined positions of the front door 70 and the trash box facility device of the Shinkansen vehicle, respectively. This can prevent the motor 34 from operating when either the lid 74 or the front door 70 is open.

A method of controlling the trash box facility device shown in FIG. 1 will be described with reference to FIG.

Normally, the power is turned on and the dust inlet 72 can be freely opened and closed. In this state, the key device 76 does not restrict the opening and closing of the lid 74. Therefore, the user can freely throw in the dust from the dust input port 72. In this case, it is preferable to provide the display panel 80 with a display means 83 such as "Dust can be thrown in".
When the waste container 60 is full, the crew member looks into the waste container 72 to check the state of the waste and then turns on the switch using the key owned by the crew member. This allows
The motor 34 is actuated, and the expandable link mechanism 20 compresses dust. The electric control sequencer 90 sends a drive signal to the motor 34 only when the ascending end detection limit switch L2, the dust entrance closing limit switch L3, and the front door closing limit switch L4 are all on.

While the telescopic link mechanism 20 is operating, the blue lamp 81 of the display panel 80 is turned on. If any of the above limit switches is not turned on, the red lamp 82
Lights up and informs the crew of the abnormality.

When the blue lamp 81 of the display panel 80 is turned on, the solenoid S1 for driving the locking rod 76a of the key device 76 installed near the dust inlet 72 is operated to move the rod 76a to the dust inlet 72 side. And the lid 74 is locked so that the lid 74 does not open. As a result, the dust input port notch lock L5 is turned on. If the dust entrance notch lock L5 does not turn on within 2 seconds, it becomes abnormal and the blue lamp 81 is turned off and the red lamp 82 is turned on.

Next, the electromagnetic clutch S2 (on) built in the pulley 32a is actuated to activate the motor 34 and the feed screw 32.
And are drivingly connected via a belt 33. The forward rotation of the feed screw 32 causes the sliding member 36 to move away from the support member 31b, whereby the dust holding means 50
Is stopped and the motor 34 is stopped when the lower end detection limit switch L1 is turned on. Even when the lower end detection limit switch L1 is not turned on even after 25 seconds have passed since the motor 34 was driven, the motor 34 is similarly stopped. After stopping the motor 34, the dust holding means 50 is kept for 1 second.
Hold in that position. Next, the motor 34 is rotated in the reverse direction to raise the dust pressing means 50, and the motor 34 is stopped when the rising end detection limit switch L2 is turned on. Even when the rising end detection limit switch L2 is not turned on even after 25 seconds have passed since the motor 34 was driven, the motor 34 is similarly stopped. In this case, unlike the case of descending, it is determined as "abnormal", the blue lamp 81 is turned off, and the red lamp 82 is turned on. When the rotation of the motor 34 is stopped by turning on the rising end detection limit switch L2, the solenoid S1 is actuated, and the rod 76a is allowed to freely open the retractable lid 74 from the dust inlet 72 side.

Thus, one cycle of dust compression is completed. When the volume does not change even if the waste is compressed a predetermined number of times or after the vehicle arrives at the terminal station, the front door 70 is opened using the key owned by the crew, and the waste container 60 becomes full. Take out the garbage bag and replace it with a new one.

When the red lamp 82 is lit,
That is, in the case of an abnormal situation, the front door 70 is opened using the key owned by the crew member, the cause of the abnormal situation is removed, and then the front door 70 is closed or left as it is.
The manual handle 39 is connected to the shaft part of the and is rotated. As a result, the dust pressing means 50 is moved to the rising end, and the trash box facility device is returned to the operable state.

EXAMPLE A trash box with a trash compression function as shown in FIGS. 2 to 4 was manufactured and mounted on a commercial vehicle of the Shinkansen for testing.

The size of the trash can with the trash compression function was matched to the trash can facility of the vehicle currently running. The external dimensions of the frame 10 are 70 cm in width and 28 cm in depth.
× The height was 94 cm. The trash container 60 used was about 60 liters and had a height of 45 cm. As the motor 34, a 25 W reverse bull motor was used. Power supply is A
C100 volt was used, but usually 0.5 A, maximum 0.
It was about 7A.

As the expandable link mechanism 20, two X-shaped links which are hinged in the vertical direction are used, and the link portions 40 are prevented from buckling by arranging them in a double direction in the depth direction. The vertical stroke at the lower end of the telescopic link mechanism 20 is 505 mm (maximum 520 mm), and the compression force is about 7 near the surface of the waste container 60 as shown in Table 1 below.
0 kgf, projection 5 of the compression plate 52 from the bottom of the waste container 60
The distance to the lower end of 2a is 12 cm (stroke 500 m
It was about 200 Kgf at the position (near m). One cycle of compression is about 50 seconds.

[0047]

[Table 1] Next, the effect of waste compaction was measured on various wastes.
Table 2 is for 100% bento, Table 3 is for 60% bento, 30% for newspaper / magazine, 10% tins / bottle, and Table 4 is for 20% bento, 60% for newspaper / magazine, can·
The case of 20% bin is shown. “A” in the table represents the distance from the upper surface of the dust container 60 to the dust surface.

[0048]

[Table 2]

[Table 3]

[Table 4] Looking at the results in Table 2, it is possible to finally pack double the weight of waste when the bento is 100%. This result is based on the assumption of garbage on the Shinkansen, which is a railroad car.For example, like a fast food restaurant, a paper cup, a bag that wrapped hamburgers, and a paper box that contained nuggets. It is expected that more waste can be packed in places where bulky items such as straws are likely to be discarded.

The results of Tables 3 and 4 also show that the packing amount can be 160%, 162%, and 1.5 times or more of the packing amount, respectively.

[0050]
