It is arranged at a closed position where the inlets 5a, 5b, 5c, 5d shown by the solid lines in FIG. 1 are closed.

First, FIG. 1 shows the case of collecting dust.
The operation will be described with reference to the operation explanatory diagrams of FIGS. 2 and 13 and the flowcharts of FIGS. 14 and 15.

When collecting dust, first, the changeover switch 81 of the operating device 80 provided in the driver's seat is switched to the loading position, and then the operation provided at the rear of the luggage box 1 in step S1. The automatic switch 91 of the device 90 is activated.
Thus, in step S2, it is determined by the limit switch LS2 whether or not the dust container A is at the lowest position.

If the dust container A is at the lowest position,
In step S3, the scraping cylinder 45 is extended.
Thereby, the scraping part 42 of the scraping device 4 is guided to the bent part 46a of the guide rail 46 from the closed position for closing the charging ports 5a, 5b, 5c, 5d shown by solid lines in FIG. , 5b, 5c, 5d toward the open position retracted above. Then, in steps S4 and S5, the limit switch LS6 confirms that the scraping-out portion 42 is placed at the open position, and then the scraping-out portion 42 is stopped at the open position [see FIG. 12 (a)].

Then, the accommodating portions A1, A2, A of the dust container A located at the lowest position according to the type of dust determined in advance.
Collect and separate the garbage into 3 and A4 respectively.

After that, in step S6, the dust container A is raised, and the guide roller 26 is guided to the curved upper portion of the guide path 25, whereby the respective storage portions A1 of the dust container A1.
A2, A3, and A4 are connected to the inlets 5a, 5b, 5
c and 5d are reversed, and after confirming that the dust container A has reached the reversal position by the limit switch LS3 in steps S7 and S8, the raising of the dust container A is stopped and a predetermined time (about 2 About a second) The dust container A is stopped at the reverse position [see FIGS. 12 (b) and 12 (c)]. As a result, the dust in each of the accommodating portions A1, A2, A3, A4 is put into the charging port 5
Each shoot 12a, 12 through a, 5b, 5c, 5d
b, 12c, and 12d guide them to the substantially central portion and separately store them in the respective storage chambers 1a.

In this way, the waste in the waste container A is stored in each storage chamber 1
After being put into a, the dust container A is lowered in step S10, and the limit switch LS1 is set in steps S11 and S12.
After confirming that the dust container A has reached the lowest position, the descent of the dust container A is stopped, and the dust container A is again arranged at the lowest position (see FIGS. 12D to 12F). .

Then, in step S13, a scraping operation is performed. In this scraping operation, the scraping cylinder 45 is retracted, and the scraping part 42 of the scraping device 4 is arranged at the closed position where the charging ports 5a, 5b, 5c, 5d are closed [see FIG. 12 (g)]. ] By further retracting the scraping cylinder 45 from this closed position, the scraping part 42 of the scraping device 4 is slid forward while maintaining this state, and when it reaches the foremost position, the scraping is performed this time. The leveling cylinder 45 is extended and slid rearward so that the inlets 5a, 5b, 5
Stop c and 5d at the closed position to close [Fig. 12 (h)
~ (K)].

Then, in step S14, it is determined whether or not a predetermined time (this time is a time sufficient to complete the scraping operation, for example, is set to about 10 seconds) after the scraping operation is started. It is determined whether or not the predetermined time has elapsed, and the process proceeds to step S15. In step S15, it is determined whether or not the scraping operation has been completed. If the scraping operation has been completed, the scraping operation is stopped in steps S16 and 17, and the scraping part 42 is arranged at the closed position. In steps S18 and 19, after confirming that the scraping-out portion 42 is placed in the closed position by the limit switch LS4, the operation is stopped and the processing is ended.

In this way, by operating the scraping part 42 of the scraping device 4 as shown in FIGS. 12 (g) to (k), the scraping part 42 forms a mountain shape in each accommodation chamber 1a. Dust can be stored in each storage chamber 1a while smoothing the top of the loaded dust.

The operation shown in FIGS. 12A to 12K is 1
Every time the automatic switch 91 of the operating device 90 is operated as a cycle, the dust container A performs the dust throwing operation.

If a predetermined time has elapsed since the scraping operation was started in step S14, the operation of the scraping part 42 is hindered by the stored dust, that is, the inside of the storage chamber 1a. It is determined that the dust is full (full amount detection means), and the process proceeds to step S20. Then, in steps S20 and 21, the scraping operation is stopped halfway, and the scraping part 42 is slid to the rear closed position side.
In steps S22 and S23, the limit switch LS4 is used to confirm that the scraping-out portion 42 has been placed in the closed position, and after stopping at this closed position, a full buzzer sounds in step S24 to finish. Not only the buzzer,
The full amount may be notified by turning on the lamp, or the buzzer and the lamp may be used together. This makes it possible to accurately detect the full amount of dust.

Furthermore, if the dust container A is not at the lowermost position in step S2, that is, if the dust container A is in the storage position [see FIG. 13 (a)], the process proceeds to step S10, and steps S10 to S10 described above are performed. 24 is performed (see FIGS. 13B to 13F), and the dust container A is placed in a state in which dust can be loaded.

That is, the automatic switch 91 is operated by the dust container A.
When the dust container is at the lowest position, the dust throwing operation is started, and when the dust container A is not at the lowest position, the dust container A is operated so that dust can be thrown into the dust container A.

Next, the case of finishing the dust loading operation will be described with reference to the operation explanatory view of FIG. 16 and the flowcharts of FIGS. 17 and 18.

First, in step S31, the end switch 92 is operated. Thus, in step S32, it is determined whether or not the dust container A is in the storage position based on the detection signal from the limit switch LS1. If the dust container A is in the storage position, the loading operation has already been completed. And ends this operation.

If the garbage container A is not in the storage position,
In step S33, it is determined whether or not the dust container A is at the lowermost position based on the detection signal from the limit switch LS2. If it is not at the lowermost position, it is determined that the dust container A is at the storage position, and this operation is performed. finish. That is, step S33
Will play an auxiliary role in the determination in step S32.

If the dust container A is at the lowermost position in step S33, the scraping part 42 of the scraping device 4 is opened in step S34, and steps S35 and S36 are performed.
The limit switch L
When confirmed in S6, the scraping portion 42 is stopped at the open position [see FIG. 16 (a)].

Thereafter, the dust container A is raised from the lowermost position in step S37, and the limit switch L indicates that the dust container A is placed in the reverse position in steps S38 and S39.
After confirming in S3, the dust container A is stopped. And
In step S40, the dust container A is held at the reverse position for a predetermined time (about 2 seconds) [see FIGS. 16 (b) and 16 (c)].

If the predetermined time has elapsed, then step S
At 41, the dust container A is lowered, and at steps S42 and 43, the limit switch LS1 is used to confirm that the dust container has been placed at the storage position, and then the descent of the dust container A is stopped [Figs. 16 (d) to (f)]. reference〕. After this step S4
The scraping unit 42 of the scraping device 4 is arranged at 4, 45 at the closed position where the charging ports 5a, 5b, 5c, 5d are closed, and the work is completed (see FIG. 12 (g)).

The end switch 92 operates only when the dust container A is at the lowest position.

Then, the lamp 97 of the operating device 90 is turned on while the scraping section 42 is operating, and the automatic switch 91 and the end switch 92 cannot be used while the lamp is turned on.

Next, the case of discharging the dust stored in each storage chamber 1a in this way will be described with reference to the operation explanatory view of FIG. 19 and the flow charts of FIGS. 20 and 21.

First, the changeover switch 81 is set to the ejection position. This turns on the power of the operating device 80 in the driver's seat.

Then, in step S51, the tilting switch 82 of the operating device 80 is actuated, whereby step S5
The discharge lamp provided on the display unit (not shown) at 2 is turned on. Next, in step S53, it is confirmed by the limit switch LS4 whether or not the scraping part 42 of the scraping device 4 is in the closed position. If the scraping part 42 is in the closed position, the process proceeds to step S60 described later and the scraping is performed. If the leveling unit 42 is not in the closed position, the process proceeds to step S54.

In step S54, the scraping-out portion 42 is once opened, and in steps S55 and 56, the limit switch L indicates that the scraping-out portion 42 is in the open position.
After confirming in S6, the scraping part 42 is stopped at the open position.

Then, in step S57, the scraping unit 4
2 is operated to the closed position, and after confirming with the limit switch LS4 that the scraping part 42 is arranged in the closed position in steps S58 and 59, the scraping part 42 is stopped at the closed position [FIG. See a)].

Then, in step S60, the dust container A is raised, and in steps S61 and 62 it is confirmed by the limit switch LS3 that the dust container A is placed in the reverse position, and then the dust container A is stopped in the reverse position. [Fig. 19
See (b) and (c)].

At the same time, in step S63, an operation switch (not shown) is operated to open the hook 75 corresponding to the discharge door 7 which discharges dust from each locking door 73 from the locking pin 73, and steps S64 and S65. After confirming that each limit switch LS9 has opened the hook 75, the hook 75 is stopped in the open state [Fig. 19 (d)].

As a result, the load box lowering lamp is turned off in step S82, and the operation ends.

By sequentially opening the discharge doors 7 one by one as described above, it is possible to discharge the dust in each storage chamber 1a in a separated state. It is also possible to open a plurality of discharge doors 7 at the same time.

Further, since the reversing loading device 2 is attached to the rear end portion of the luggage box 1, the reversing loading device 2 does not interfere with oncoming vehicles even on narrow roads. It can be done smoothly.

Incidentally, the full amount detecting means, like the pressure detector PS (see the chain double-dashed line in FIG. 1) for detecting the pressure of the pressure oil supplied to the scraping cylinder 45, scrapes the scraping device. The load acting on the portion 42 may be detected.

At this time, the dust collecting operation is performed by referring to FIG.
4 and the dust collecting operation shown in the flow chart of FIG. 15, between steps S13 and S14, as shown in FIG.
As shown in FIG. 5, a judgment step S14a for judging whether or not the pressure value of the scraping cylinder 45 is equal to or more than a predetermined value is added.

Therefore, in step S14a, when the pressure detected by the pressure detector PS becomes equal to or higher than the predetermined value, the operation of the scraping-out portion 42 is hindered by the stored dust, that is, the storage chamber. It is determined that the dust in 1a is full, and step S is performed as in the above-described embodiment.
20, the scraping operation is stopped halfway, and the scraping part 42 is slid to the rear close position side, and the scraping part 42
Is placed at the closed position and the vehicle is stopped at this closed position, then a full buzzer sounds and the process ends (steps S21 to S24).

The waste container is divided in accordance with the above, and a discharge door is provided at the rear end of the storage chamber so that the discharge door can be opened and closed. By designating, and opening only the designated discharge door and discharging only the dust in the corresponding storage chamber, the dust can be separately collected and sorted.

According to the garbage collection vehicle of the third aspect of the present invention, the full quantity detecting means detects that the garbage in the packing box of the garbage collection vehicle is full, and based on the detection result. The control device stops the scraping operation of the scraping device midway, places the scraping part in the closed position, and notifies the full amount, so that the full amount of dust in the packing box can be accurately grasped. Therefore, it is possible to prevent leakage of dust due to the full amount, and it is possible to quickly perform work processing for the full amount.

According to the garbage collection vehicle of the fourth aspect of the present invention, as the full amount detecting means, it is determined whether or not a predetermined time has elapsed since the start of the scraping operation of the scraping device, and the predetermined amount is determined. When the time has elapsed, it is possible to reliably detect the full amount of dust by determining that the operation of the scraping unit is blocked by dust.

According to the garbage collection vehicle of the fifth aspect of the present invention, as the full amount detecting means, the load acting on the scraping portion of the scraping device is detected, and when the load exceeds a predetermined value, the scraping is carried out. By determining that the operation of the unit is blocked by dust, it is possible to reliably detect the full amount of dust.
