Is configured to pass through a locus eccentric to the rear of the vehicle by a predetermined amount a from the rotating shaft 38 when the piston rod 50 expands and contracts by sliding.

In the cylinder device 55, when the lower engagement piece 30 does not slide away from the upper engagement piece 31 by a predetermined amount or more in the clamped state, the piston rod 58 is further extended. The rotation shaft 3
A moment is generated in a reversing direction (counterclockwise direction in FIG. 1) centered at 8, and the clamp portion is reversed and rotated about the rotation shaft 38 as a rotation center.

The garbage container 27 is integrally formed of a synthetic resin material, and the engaged portion 28 formed on the side surface 27a is formed with a concave portion 27b on the side surface 27a so that the upper end of the concave portion 27b is formed. The upper engaged portion 28a extending horizontally along the edge, and the upper engaged portion 2
8a, a metal side bar 28b as a lower engaged portion extending in the horizontal direction at a predetermined interval at a lower position.

The left and right ends of the side bar 28b are fixed to the left and right edges of the recess 27b.

A rolling wheel 27c is provided on the lower part of the side surface of the trash container 27 opposite to the side surface 27a on which the engaged portion 28 is formed.
Are provided rotatably.

Next, the operation of the first embodiment will be described.

In the first embodiment, the garbage collection vehicle 2
The garbage container 27 is placed behind the upper portion, and the upper engaging piece 31 and the lower engaging piece 30 of the engaging portion 26 are positioned between the upper engaging portion 28a and the side bar 28b in the concave portion 27b. Position as shown in 1.

Next, when the reversing device 25 is operated, the cylinder device 55 extends the piston rod 58 and slides the upper engagement piece 31 in a direction away from the lower engagement piece 30. Then, the upper engagement piece 31
But, in the separating direction, it comes into contact with the upper engaged portion 28a of the engaged portion 28 and clamps.

As shown in FIG. 4, with the extension of the piston rod 58 of the cylinder device 55, the garbage container 27 is raised in a substantially vertical direction.

At this time, due to the extension of the piston rod 58, the inner structure 39 slides substantially vertically upward with respect to the end edge 4 to form the inner wall portion 40 integrally with the inner structure 39. , 40 are raised.

Therefore, the rotation shaft 3 is attached to the inner wall portions 40, 40.
The slide hinge member 36 connected via the arm 8 is also moved up to set the center position of the rotation shaft 38 above the edge 4 as shown in FIG.

Then, the side bar 28b is brought into contact with the lower engaging piece 30 to be engaged with the lower engaging piece 30 to be in a clamped state.

For this reason, the bottom 27 d of the trash container 27 is lifted up by a predetermined amount 1 from the ground surface 60 and inverted, so that the bottom 27 d does not interfere with the ground surface 60 and the garbage container 27 is smoothly inverted. Done in

Moreover, if the trash container 27 is placed on the ground surface 60 as described above, the trash in the trash container 27 can be turned over and put into the trash input port 3.

For this reason, it is not necessary to lift and place the trash container 27 containing the trash having a predetermined weight up to the pedestal as in the related art, and the workability of collecting the trash is good.

In the clamped state, the cylinder device 5
When the piston rod 58 of FIG. 5 is further extended, the piston rod 58 extends and contracts by a predetermined amount a from the rotation shaft 38.
Due to the eccentricity, a moment is generated in the reverse direction about the rotation shaft 38 that has been raised to a position above the edge 4.

With this moment, as shown in FIG.
The upper engagement piece 31 and the lower engagement piece 30, which are the clamps, clamp the upper engaged portion 28a and the side bar 28b of the trash container 27 around the rotation shaft 38 as a rotation center. , Turns counterclockwise in the figure.

At this time, the positioning pins 32a are disengaged from the pin holes 54a of the outer structure 50, and the inner structure 39 is rotated about the rotation shaft 38 together with the outer structure 50. Move.

Therefore, the garbage in the garbage container 27 is
It is thrown into the refuse inlet 3. At this time, since the upper and lower engaging pieces 31, 30 clamp the upper engaged portion 28a and the side bar 28b, which are the engaged portions, in the separating direction, the trash container 27 may fall off. There is no.

Next, when the piston rod 58 is shortened, a moment in the reverse rotation direction about the rotation shaft 38 is generated. Due to this moment, the rotating shaft 3
8 with the upper engaging piece 31 and the lower engaging piece 30 being the clamp portions clamping the upper engaged portion 28a and the side bar 28b of the garbage container 27, Turn clockwise in the opposite direction.

At this time, the positioning pins 32a are inserted into the pin holes 54a of the outer structure 50.

Further, when the piston rod 58 of the cylinder device 55 is shortened, the lower engagement piece 30 is separated from the side bar 28b and disengaged, and then the bottom portion 27d is released. Then, the upper engagement piece 31 is separated from the upper engaged portion 28a by being lowered onto the ground surface 60, the engagement is released, and the clamped state is released.

Then, the inner structure 39 slides downward in the vertical direction, and as shown in FIG.
8 is located below the edge 4.

Therefore, there is no protrusion of the turning shaft 38 and the like upward from the insertion port edge 4 in a so-called unclamped state without using the reversing device 25, and furthermore, from the edge 4 to the rear of the vehicle. The amount is also reduced as compared with the related art, so that the risk of obstruction when manually performing garbage collection work is reduced, and workability can be improved. Further, the inner structure 3
9 is raised to the position of the locking hole 53a formed in the side wall 53 of the outer structure 50 by sliding movement of the inner structure 39, as shown in FIG. The locking projection piston 45b is connected to the spring member 45.
With the urging force of c, it is made to protrude into the locking hole 53a and locked.

As described above, by the locking portion 45 provided on the inner structure 39, the rotating shaft 38 is positioned above the edge 4 which is the position of the set center of rotation. The sliding movement of the inner structure 39 is stopped.

Therefore, almost all the driving force of the cylinder device 55 is used for the rotational movement, so that there is almost no energy loss, and the rotational trajectory of the rotating garbage container 27 is stable, and By doing so, the dust in the garbage container 27 can be stably thrown into the dust inlet 4.

The locking member 45 is provided with a crank member 47 as a lock releasing means for releasing the lock when the piston rod 58 is restored by the shortening of the piston rod 58 after inversion.
Is provided.

After the reversal, the inner member 39 and the outer member 50 rotate clockwise due to the shortening of the piston rod 58 to the position shown in FIG. As shown in FIG. 5, the contact portion 48 is brought into contact with the rear surface of the base 32.

For this reason, the crank member 47 rotates counterclockwise in FIG. 5 about the rotation shaft 46 as a rotation center, and moves the engaging projection piston 45b to the right in the figure. Move.

Therefore, this locking projection piston 45b is
It moves against the urging force of the spring member 45c, and the tip is pulled out from the locking hole 53a to release the locking of the inner structure 39 in the sliding direction.

For this reason, when the inner structure 39 is lowered to the position shown in FIG. 1 and restored by the shortening of the piston rod 58, the inner structure 39 slides smoothly downward by its own weight to shift the position of the rotating shaft 38. , Is located below the edge 4.

As described above, while the inner and outer rotating structures 39 and 50 are being rotated around the rotating shaft 38, the position of the rotating shaft 38 is maintained at the edge 4. In addition to being held at a position higher than the upper surface portion 4a, the position of the rotating shaft 38 is maintained at a position higher than the upper surface portion 4a of the edge 4 even when the reversing operation is restored.

After the reversal of the reversing operation, the rotation shaft 38
Since the inner structure 39 is slid down together with the slide hinge member 36 and stopped at a position lower than the edge 4, there is almost no possibility that the rotating shaft 38 is protruded and remains. There is no obstacle to throwing trash.

Further, in the first embodiment, the positioning pins 32a provided on the base 32 which is the edge side structure are provided.
However, when the piston rod 58 extends, the lower engagement piece 30 is substantially fixed in the substantially vertical position by engaging with the pin hole 54a, and remains as it is without rising together with the inner structure 39. . At this time, the positioning pin 3
Since 2a is engaged with the pin hole 54a, the outer structure 50 does not fall downward by its own weight.

As described above, since the upper engaging pieces 31 rise independently, the upper and lower engaging pieces 31 and 30 are separated from each other in the vertical direction to be in a clamped state.

When the rotation is started in the clamped state, the positioning pin 32a is pulled out of the pin hole 54a, the engagement is released, and together with the upper engagement piece 31,
The lower engagement piece 30 is also rotated about the rotation shaft 38.

At this time, the locking projection piston 45b of the locking portion 45 projects into the locking hole 53a and is locked, and the relative sliding movement of the inner structure 39 with respect to the outer structure 50 is stopped.

As described above, since the inner structure 39 is substantially fixed to the outer structure 50, the inner and outer structures 39 and 50 have the rotation shaft 38 as the center of rotation. A moment occurs.

Therefore, the dust container 27 can be rotated while being clamped. After the inversion, the piston rod 58 is shortened to the position shown in FIG.
When the inner structure 39 and the outer structure 50 are rotated clockwise and restored, as shown in FIG.
The outer structure 5
The positioning pin 32a is inserted into and engaged with the 0 pin hole 54a.

Therefore, the outer structure 50 is not affected by the expansion and contraction of the piston rod 58, and the movement in the substantially vertical direction is restricted.

At this time, the locking projection piston 45b of the locking portion 45 is pulled out from the locking hole 53a, and
Is released, so that the inner structure 39 can be slid in a substantially vertical direction with respect to the outer structure 50. Therefore, again, the upper and lower engagement pieces 31, 30 are
Due to the shortening of the piston rod 58, the piston rod 58 moves in the approaching direction and the clamped state can be released.

Thus, with one cylinder device 55,
From the engagement of the trash container 27 with the engaged portion 28, the rotation shaft 38
, A series of operations up to the reversal of the trash container 27, the reversal in the opposite direction, and the disengagement can be performed. Therefore, by arranging the substantially cylindrical cylinder device 55 along the substantially vertical direction, a limited space at the rear of the vehicle can be effectively used, and the space efficiency is good.

Further, as compared with the conventional reversing device 5 for the garbage container 1, the number of parts such as the link members 6 to 9 can be reduced, the weight can be reduced, and the manufacturing cost can be reduced.

Further, since the number of components such as the link members 6 to 9 is reduced and the inner structure 39 which slides in a substantially vertical direction is employed, the inner structure 39 and the inner structure 39 which constitute this rotary structure are substantially used. The amount of the rearward protrusion of the refuse collection vehicle 2 is suppressed only by the amount of the rearward projection from the edge 4 by the thickness of the outer structure 50. Further, unlike the related art, when the horizontal links 8 and 9 rotate, the vertical link 7 does not protrude rearward of the vehicle.

Further, since the upper engagement piece 31 and the lower engagement piece 30 are located in the recess 27b of the trash container 27 and clamp the upper engaged portion 28a and the side bar 28b, The amount of protrusion of the dust container 27 to the rear edge of the dust container 27 in a clamped state can also be suppressed.

Therefore, in either the state where the trash container 27 is clamped or the state where the trash container 27 is not clamped, the amount of protrusion toward the rear of the vehicle is reduced. When manually charging the charging port 3 without using the port 25, the risk of hindering the operation is reduced. Further, even when the space of the garbage collection site is limited, the possibility of interference with other garbage containers 27 is reduced, and the garbage collection workability can be improved.

The direction in which the dust container 27 engages with the engaged portion 28 is such that the upper engagement piece 31 is
And is clamped in the expanding direction, so that the engaged portion 28 of the garbage container 27
The force in the tensile direction acts substantially vertically. In general, it is known that the side surface of the trash container 27 made of a synthetic resin material has greater resistance to stress acting in the tensile direction than resistance to stress in the compressing direction.

Therefore, the possibility of deformation is reduced as compared with a conventional case in which a force in the compression direction acts on the side surface of the trash container 1.

The engaged portion 28 of the garbage container 27
The upper engaged portion 28a extending in the horizontal direction,
A horizontally extending side bar 28b is provided below the upper engaged portion 28a at a fixed interval.

For this reason, the substantially vertical pulling force acting between the upper engaged portion 28a and the side bar 28b is applied substantially horizontally to the side edges of the concave portion 27b formed at both ends of the side bar 28b. Distributed and supported. The recess 2
When the recess 27b is integrally formed, the both side edges of 7b are easy to form a wall thickness or a reinforcing rib shape. Therefore, since the portion on which the stress acts can be configured with a structure having high rigidity, the possibility of deformation is further reduced.

Further, in this embodiment, the locking portion 45
Accordingly, the sliding amount of the inner structure 39 can be set to a predetermined amount. Therefore, if the expansion is stopped at a predetermined position where the tensile stress does not act much after the clamping, the possibility of deformation is further reduced.
