The tailgate 3 is formed in a box shape by doors 3a and 3d, side walls 3b and 3b, and a bottom plate 3c, and the front side is connected to the rear opening of the body 2 in the state shown in FIG.

The dust loading device 4 includes a deflector 5 that is fixed inside the tailgate 3, guide rails 6 and 6 that are provided on both side walls 3 b and 3 b of the tailgate 3 along the deflector 5, and guides thereof. A loading plate 7 supported on the rails 6 and 6 via rollers (not shown) so as to be movable up and down, a scraping plate 8 and a pressing plate 10 are provided.
Further, the dust loading device 4 includes a cylinder (not shown) that moves the loading plate 7 up and down along the guide rails 6, 6, a cylinder (not shown) that rotates the scraping plate 8 around the pivot 12, and the pivot 12. And a cylinder (not shown) for rotating the pressing plate 10.

  When the doors 3a and 3d provided at the rear part of the tailgate 3 are opened, the dust inlet 9 is opened. . In this embodiment, the dust is assumed to be a plastic container. The dust loading device 4 compresses the thrown dust and scrapes it into the body 2 side.

The scraping plate 8 and the pressing plate 10 are pivotally attached to the lower portion of the loading plate 7 by a pivot shaft 12 so as to be rotatable.
As shown in FIG. 1, the pressing surface 10 a of the pressing plate 10 has a cross section arranged in an arc shape with the pivot 12 as the center. A plurality of projections 10b that press against the dust are provided on the pressing surface 10a.
The scrambling surface 8a of the scrambling plate 8 is planar. Plural protrusions 8b that press against the dust are also provided on the scraping surface 8a.
The end 8b-1 of the protrusion 8b also serves as a member for removing dust clogged between the protrusions 10b and 10b of the pressing surface 10a. Hereinafter, this is called a dust removing member.

FIG. 2 is a plan view of the pressing plate 10 and the scratching plate 8 drawn so that the pressing surface 10a of the pressing plate 10 and the scratching surface 8a of the scratching plate 8 can be seen.
A pivot 12 is arranged on the rotation shaft 13 shown in FIG. 2, and the pivot 12 is inserted into holes provided at the ends of the loading plate 7, the scratching plate 8 and the pressing plate 10, thereby loading the loading plate. 7 is connected to the scraping plate 8 and the pressing plate 10.
As shown in FIG. 2, the scratching plate 8 has a main body portion 8 c that extends along the rotation shaft 13. The scraping surface 8a and the protrusion 8b are integrally held by the main body portion 8c. Arm portions 8d and 8d coupled to both ends of the main body portion 8c are extended to the rotating shaft 13. The pressing plate 10 is disposed so as to fit in a space surrounded by the main body portion 8c and both arm portions 8d, 8d.

The protrusion 8b of the scraping surface 8a is formed in a saw blade shape arranged linearly as shown in FIG. 1, and has a multi-row configuration perpendicular to the rotating shaft 13 as shown in FIG. Has been placed.
The protrusion 10b of the pressing surface 10a is formed in a saw blade shape arranged in an arc shape as shown in FIG. 1, and has a multi-row configuration perpendicular to the rotating shaft 13 as shown in FIG. And it arrange | positions along the rotation axis | shaft 13 in the position which becomes between the protrusions 8b of the picking surface 8a.

  As shown in FIGS. 1 and 2, the dust removing member 8b-1 that is an end portion of the protrusion 8b is close enough not to contact the pressing surface 10a and is disposed between the protrusions 10b and 10b.

  Furthermore, the dust loading device 4 of the present embodiment includes a control device (not shown) that drives the cylinders described above to control the lifting and lowering of the loading plate 7 and the rotation of the scraping plate 8 and the pressing plate 10. The operation described in is performed.

Next, the operation of the dust loading device of this embodiment will be described.
As a premise, the control device holds the pressing plate 10 with the pressing surface 10a facing the bottom plate 3c as shown in FIG. If the pressing plate 10 is fixed at the angle shown in FIG. 1, a cylinder for rotating the pressing plate 10 and its drive control system are unnecessary. The pressing plate 10 may be formed integrally with the loading plate 7 or may be bonded to the loading plate 7 by welding or the like.
The control device controls the loading operation with the following (1) to (4) as one cycle. This operation may start from any state, but the normal stop state is the state shown in FIG. 6 and will be described from this state.

(1) Scratching plate reverse rotation step As shown in FIG. 6, the loading plate 7 is in the raised position, and the scratching plate 8 is rotated from the state in which the scratching surface 8a is located on the front end side of the pressing surface 10a. Then, the scraping surface 8a is rotated to the rear end side of the pressing surface 10a to obtain the state shown in FIG.
At this time, if the pressing plate 10 is also rotated in the same manner as the scoring plate 8, the dust once scraped into the body 2 may flow backward. However, since the pressing plate 10 does not rotate, there is an effect of preventing the reverse flow of the dust scraped into the body 2 as compared with the case where the pressing plate 10 rotates.

(2) Lowering process (primary compression process)
Next, as shown in FIG. 3 and FIG. 4, the loading plate 7 is lowered to bring the pressing surface 10a closer to the bottom plate 3c. At this time, the protrusion 10b is pressed against the dust on the bottom plate 3c to make a hole, and air is discharged. The dust is compressed by being sandwiched between the pressing surface 10a and the bottom plate 3c while discharging air (primary compression). Further, since the scraping surface 8a is arranged on the dust inlet 9 side, it is possible to prevent the dust being compressed from being discharged from the dust inlet 9.

(3) Scratch plate forward rolling process (secondary compression process)
Next, the scratching plate 8 is rotated to rotate the scratching surface 8a to the front end side of the pressing surface 10a to obtain the state shown in FIG. At this time, the scraping surface 8a rotates and moves so as to draw a trajectory that occupies almost the entire space surrounded by the pressing surface 10a, the bottom plate 3c, and the side walls 3b and 3b so that dust does not pass through. At the same time, the dust primarily compressed in the descending step is sandwiched and compressed between the scraping surface 8a and the inclined surface 3c-1 at the front end of the bottom plate 3c (secondary compression). At this time, the protrusion 8b of the scratching surface 8a acts on the dust in the same manner as the protrusion 10b of the pressing surface 10a. That is, the protrusion 8b is pressed against the dust to make a hole, and the air is discharged.

  Further, in this step, the dust removing member 8b-1 which is the end of the protrusion 8b removes the dust clogged between the protrusions 10b and 10b of the pressing surface 10a. In other words, the dust removing member 8b-1 moves between the projections 10b and 10b in the process of relative movement with the pressing plate 10, thereby scavenging the dust clogged between the projections 10b and 10b.

(4) Lifting step Next, the loading plate 7 is lifted and returned to the state shown in FIG. At this time, the scraping surface 8a and the front side surface 10c of the pressing plate 10 rise along the inclined surface 3c-1 and push the dust into the body 2.

  Furthermore, when performing 2 cycles or more, it returns to the said rake plate reverse process of said (1), and repeats 1 cycle of said (1)-(4).

  In the above embodiment, the dust removal operation by the dust removal member 8b-1 is performed by the scraping operation of the scoring plate 8. Regardless of this, the scraping plate 8 is stopped and the pressing plate 10 is rotated, or both the scraping plate 8 and the pressing plate 10 are rotated to move the dust removing member 8b-1 between the projections. Thus, the dust removal operation may be executed. Also in this case, dust remaining on the pressing surface 10a can be removed. However, if the dust removal operation is performed outside the series of loading operations, the efficiency is inferior.

  In the above embodiment, the dust removing member 8 b-1 is provided on the scratching plate 8 and held on the loading plate 7 via the scratching plate 8. Regardless of this, the dust removing member may be held on other portions such as the side wall 3b. Also in this case, dust remaining on the pressing surface 10a can be removed. However, when the scoring plate 8 is provided, the structure may be complicated in order not to interfere with the scoring plate 8.

  Regardless of the embodiment described above, the protrusion 8b may not be provided on the scratching plate 8. However, the dust removing member is provided independently. However, since there is no protrusion that presses the dust in the secondary compression step described above, there is a possibility that compression of the container such as a plastic bottle with respect to the dust becomes inefficient.

  The shape, number, and arrangement of the protrusions that press against the dust and the dust removing member are arbitrary. For example, a number of protrusions that press against the dust may be arranged in a dotted pattern as conical protrusions. The shape, number, and arrangement of the dust removing member are appropriately selected according to the configuration of the protrusion that presses against the dust.
