The discharge plate 35 is a plate-like body that is formed to have substantially the same width and height as the dust storage box 2 and slides back and forth in the dust storage box 2 by an expansion and contraction operation of a discharge cylinder (not shown). It is configured.

  Next, a dust loading operation by the loading device 4 configured as described above will be described.

  First, as shown in FIG. 1, with the lifting cylinder 45 and the swing cylinder 48 both extended, the swing cylinder 48 is retracted to swing the compression plate 46 backward in the upper part of the dust box 3 (inverted). Step: See FIG. 2 (a) → (b)).

  Subsequently, the elevating cylinder 45 is retracted to lower the compression plate 46 in the dust box 3 via the sliding plate 41 (lowering process: see FIGS. 2B to 2C).

  After that, by extending the swing cylinder 48, the compression plate 46 is swung forward at the bottom of the dust throwing box 3, so that the dust thrown into the dust throwing box 3 from the throwing port 32 is taken into the dust. The bottom of the charging box 3 is compressed (compression process: see FIG. 2 (c) → (d)).

  Then, the elevating cylinder 45 is extended to raise the compression plate 46 in the dust container 3 via the sliding plate 41 and pack the compressed dust into the dust container 2 (ascending process: FIG. 2 (d) → (a)).

  Accordingly, by operating the loading device 4 with the above-described operation as one cycle, the dust is sequentially packed into the dust container box 2.

  By the way, in the garbage truck which collects dust in this way, the measurement stand 6 is provided at the bottom of the dust container 3. The measuring table 6 measures the mass of a dust container including dust by placing a dust container A (see FIG. 7) containing dust on the upper surface thereof, as shown in FIGS. 3 and 4. It is slidably provided back and forth in a cover member 61 connected to the bottom of the dust box 3.

  Specifically, slide rails 62 are provided in the front and rear directions on the left and right side surfaces of the cover member 61 formed in a U shape when viewed from the back, and the slide base 63 is moved forward and backward along the slide rail 62.

By sliding the measuring table 6 back and forth via the slide table 63, the measuring table 6 is accommodated in the cover material 61, and the garbage throwing box 3 is placed. It is arranged to be stored at a storage position for storing in the lower part of the bottom and a measurement position for pulling backward from the cover material 61 and projecting backward from the lower part of the bottom of the dust bin 3. And the measuring stand 6 arrange | positioned at each of these positions is made to be held in a stable state at each position by an appropriate lashing device 64.

  Further, an appropriate number (two in the illustrated example) of recesses 65 are formed on the mounting surface 6a, which is the upper surface of the measuring table 6, with a predetermined interval in the width direction of the vehicle as shown in FIGS. ing. Each recess 65 is for inserting and arranging the bottom portion of the dust container A in the recess 65 during mass measurement, and is formed in accordance with the size of the dust container A. On the peripheral surface of the recess 65, readers 7 are provided, for example, at four locations at equal intervals. These readers 7 are for reading the information written in the IC tag 8 attached to the dust container A shown in FIG. Therefore, the IC tag 8 is attached to an appropriate position on the bottom peripheral surface of the dust container A so as to correspond to the reader 7.

  Since the plurality of readers 7 are arranged in the recess 65 as described above, the information on the IC tag 8 can be read by any one of the readers 7 if the dust container A is placed in the recess 65. Note that the number of readers 7 may be appropriately determined according to the accuracy of the readers 7.

  Further, in addition to the user (dust discharger) and the collection area, the IC tag 8 is preliminarily written with information necessary for management described later, such as the type of dust and the type of the dust container A.

  Therefore, when throwing dust into the garbage collection vehicle 1, the dust container A is placed in the recess 65 of the measuring table 6 arranged at the measurement position, so that the mass measurement of the dust container A and the information of the IC tag 8 are performed. Is read at the same time, and then the dust in the dust container A is put into the dust throwing box 3 through the throwing port 32.

  FIG. 8 is a block diagram showing a control system of the dust measuring system for processing based on the measured mass and information on the IC tag.

  The mass of the dust container A containing the dust measured by the measuring table 6 and the information of the IC tag 8 read by the reader 7 are input to the processing unit 91 of the control device 9. Based on the above, the mass of the dust in the dust container A is calculated. That is, by calculating the mass of the dust container A itself from the data recorded in the memory 92 in advance from the type of the dust container A in the information of the IC tag 8, and subtracting the mass of the dust container A itself from the measured mass. calculate.

  Then, together with the calculated dust mass, the user information of the read IC tag 8, the type of dust (for example, the type of incombustible material or combustible material), the date and time of input, and the like are recorded in the memory 92. Further, the information is printed out by the printer 93 as necessary.

  Note that the control device 9 and the printer 93 are provided, for example, in the driver's seat.

  As described above, the dust container A can be measured and the information read from the IC tag 8 can be simultaneously performed only by placing the dust container A in the recess 65 of the measuring table 6. Thus, it is possible to efficiently collect dust at each collection site, and it is possible to collect charges based on each information such as the mass of the input dust obtained.

  Note that the type of dust can be determined from the date and time when the collection date for each type of dust is determined. That is, by recording the collection date for each type of dust in the memory 92 in advance, it is possible to determine without collecting the date on the IC tag 8.

  Further, the base station 95 collectively manages information such as the mass of the dust collected at the time of throwing in the dust recorded in the memory 92 as described above, for example, operation such as setting the operation schedule of each garbage collection vehicle in the future. Can contribute to management.

  In this case, in order to manage the above-described information obtained at the time of throwing in the dust by the base station 95, it may be performed using a recording medium such as a magnetic disk system or an optical disk system, or the control as shown in FIG. You may make it transmit from the apparatus 9 to the base station 95 through the transmitter 94. FIG.

  Further, by installing the GPS in each garbage collection vehicle and managing the vehicle position information by the base station 95 in addition to the various information described above, more detailed operation management data can be obtained.

  FIG. 9 shows another example of arranging a reader.

  A plurality of readers 7 shown in FIG. 9 are provided at a predetermined interval in the width direction of the vehicle so as to be substantially flush with the upper surface of the measuring table 6. Correspondingly, it may be provided on the bottom surface of the dust container.

In addition, the same effects as described above can be obtained, and the processing in the base station 95 can be performed in the same manner.

  FIG. 10 shows still another example of arranging a reader.

  The reader 7 is provided close to one side of the safety bar 10 provided along the lower edge of the input port 32 of the dust input box 3.

  The safety bar 10 is for urgently stopping the operation of the loading device 4, and can be rotated in the vertical direction through the attachment arms 11 connected to the lower end edge of the insertion port 32 near the both ends. Is provided. Then, when the operator deliberately rotates the safety bar 10 intentionally or with a dust container or the like coming in contact, the operation of the loading device 4 is stopped urgently. Work is done safely by avoiding accidents such as being caught.
