The operation of the hydraulic cylinder devices 39 and 51, that is, the operation of the hydraulic lifter 13 is controlled by inputting an up operation command or a down operation command from the operation panel 93. When an operation prohibition command is input from the data processing unit 91, the operation is performed. The lifting operation of the hydraulic lifter 13 is prohibited regardless of the operation command from the panel 91.

The voice identification device 77 enters an operating state when the ID information read adequacy determining unit 83 determines that the ID information cannot be read, inputs a voice signal from the microphone 95, and identifies the input voice signal. Character information display 97
When the ON signal is input from the confirmation button 99, the character information is output to the ID identifying unit 81. Next, the operation of the waste collection device having the above-mentioned configuration will be described.

When collecting the wastes thrown into the waste container 53, the upper engaging portion 59 of the waste container 53 in the upright posture (normal posture) is first placed with the lifter plate 27 in the lowered position. Fixed hook 45 of lifter plate 27
Are hooked and engaged as shown in FIG. At this point, the ID tag 67 of the waste container 53 faces the antenna 63, and the ID tag 67 indicates the I of the waste container 53.
The antenna 63 is used by the transmission / reception processing unit 79 to receive the D information. The ID information read suitability determination unit 83 determines whether or not the ID information is correctly read based on the reception status of the transmission / reception processing unit 79.

If the ID information is read correctly,
The ID information from the ID tag 67 is transferred to the ID identifying unit 81, and the ID identifying unit 81 identifies the ID of the waste container 53 based on the read ID information. The identification information of this ID is sent to the data processing unit 91. On the other hand, if the ID information is not correctly read, the hydraulic circuit 75
An operation prohibition command is output to the warning lamp 87, a lighting command is output to the warning lamp 87, and a ringing operation command is output to the buzzer 89. As a result, the operation command from the operation panel 93 is invalidated, the lifting operation of the hydraulic lifter 13 is prohibited, the warning lamp 87 is turned on, and the buzzer 89 sounds to alert the operator.

At this time, the voice discriminating device 77 is activated and the voice discriminating device 77 waits for an input of a voice signal from the microphone 95. Under this condition, when the worker reads the ID number displayed on the waste container 53, the voice signal of the ID number is transmitted to the microphone 9.

7 identifies the input voice signal and displays character information on the display 97.
Output to. Thereby, the display device 97 displays the character information of the voice recognition result.

The worker looks at the character information displayed on the display 97 to check whether the ID number is correctly identified, and if correct, presses the confirmation button 99. As a result, an ON signal is input to the voice identification device 77 from the confirmation button 99, and the voice identification device 77 outputs the ID information as the identification result to the ID identification unit 81.
Transfer to. As a result, the ID identifying unit 81 identifies the ID of the waste container 53 based on the ID information input by voice. The identification information of this ID is sent to the data processing unit 91,
The output of the operation prohibition command of the hydraulic circuit 75, the lighting command of the warning lamp 87, and the operation command of the buzzer 89 are canceled.

As a result, the operation command from the operation panel 93 becomes valid, the warning lamp 87 is turned off, the buzzer 89 stops ringing, and the waste container 53 for which the ID information reading failure has occurred is also collected. You will be in a state where you can get rid of. If the voice identification of the ID number is not good, the voice identification device 77 may be in a state of waiting for re-input of the voice signal from the microphone 95 by a timeout process or the like because the confirmation button 99 is not pressed.

When an up operation command is issued by an operator operating a button on the operation panel 93, the hydraulic cylinder device 39 drives the main link 23 to rotate around the pivot 29 in the counterclockwise direction in FIG. 27 moves from the lowering position to the reverse rising position. With the movement of the lifter plate 27, the movable hook 49 is pivotally displaced from the released position to the engagement position, and the movable hook 49 is hooked and engaged with the engagement bar 61 of the waste container 53. This makes the waste container 5
3 is locked to the lifter plate 27.

When the waste container 53 is lifted from the lowering position and turned upside down and located at the reverse rising position, the wastes contained in the waste container 53 fall into the waste input hopper 9 and the inside of the bucket body 7. To be collected.
The weight weighing device 19 uses the lifter plate 27 for the waste container 5
The weight of the waste container 53 is measured at the initial stage of the lifting process of 3 (when the waste container 53 is lifted from the ground). This weight measurement is referred to as waste storage weight measurement.

The weight value of this waste storage weight measurement is input to the weight calculation device 69. When the down operation button is pressed after the wastes have been dropped and discharged, the main link 23 is rotationally driven around the pivot 29 in the clockwise direction in FIG. 2 by the hydraulic cylinder device 39, and the lifter plate 27 is moved from the reverse rising position to the lowering position. Move to. As a result, the empty waste container 53 descends and returns to the ground in the original standing posture.

The weight measuring device 19 is in the latter stage of the process of returning the waste container 53 by the lifter plate 27 (just before the waste container 53 lands, and this measuring position is the same position as the waste storing weight measuring position). May be)
At, the weight of the waste container 53 is measured, and the measured value is output to the weight calculation device 69. This weighing is called empty weighing.

The weight calculation device 69 calculates the net waste collection weight by subtracting the measurement value of the empty weight measurement from the measurement value of the waste storage weight measurement, and outputs the calculation result to the data processing unit 91 together with the weight measurement value data. The data processing unit 91 inputs the weight measurement value data and the net waste collection weight data from the weight calculation device 69, and writes the data in the ID tag 67 of the waste container 53 and identifies the data in the handy terminal 77 connected to the connector. The process of outputting together with the completed ID information is executed.

The waste collection weight calculation may be simplified by omitting the empty weight measurement and subtracting the standard empty weight of the waste container 53 from the measurement value of the waste storage weight measurement. In this case, the standard empty weight of the waste container 53 may be set in advance, or may be set for each waste container 53 by reading the standard empty weight data from the ID tag 67 of the waste container 53. Further, the calculation may be performed by a host computer that downloads the data written in the handy terminal 77.

As a result, a signal indicating the net waste collection weight is transmitted from the antenna 63 to the ID tag 67, and the ID tag 6
The net waste collection weight of this time is written in 7, and the weight measurement value and the net waste collection weight of this time are stored in the storage unit of the handy terminal 77 together with the ID information of the waste container 53, the collection date and time, and the like. The information written in the memory of the handy terminal 77 is downloaded to the host computer by the handy terminal 77 being communicatively connected to the host computer at a waste collection center or the like, and the host computer issues a bill for each user. And so on.

FIG. 5 shows another embodiment of the control system of the waste collection system according to the present invention.
