The alarm signal section to be emitted and its release signal section 46a are the full signal section of the container full detection means (not shown).

Next, the operation will be explained based on the control system diagram in FIG.

First, when the main switch 26 is turned on, the container 1
2 is connected and the inspection port 9 is closed by the lid 10, the connection signal section 25a and the closure signal section 24b each issue a signal, and the AND circuit 27 issues a signal.

Subsequently, when the shutter 5 is opened and the open signal section 21a sends a signal, the fixed time operation signal section 42a sends a signal to drive the screw conveyor 15 for a certain period of time, and when the driving is completed, the end signal section 42b sends a signal.

In this state, when garbage is input from the input port 4,
The dust naturally falls within the dust chute 3 and passes through the microwave area 20 of the dust detecting means 18, the sensor 19 detects the flow of the dust, and the detection signal section 18a transmits the signal.

In response to the detection signal, the operation signal section 43a transmits, the screw conveyor 15 is driven, and the garbage is compressed and stuffed into the container 12, and the timer operation signal section 44a transmits, the timer is activated, and when the timer is up, the end signal section 4
4b sends a signal, the stop signal section 43b sends a signal via the AND circuit 28 and the OR circuit 36, and the screw conveyor 15
stops.

Further, when the knot circuit 39 is sending a signal, the AND circuit 29 sends a signal and inputting it to the detection signal section 18a, and when garbage is thrown in again and the garbage is detected, the above operation is repeated and the garbage is stuffed into the container 12. It will be done.

3 during the above operation, and if a bridging phenomenon occurs in the hopper 7, the bridging phenomenon detection means 23 detects it, the generation signal section 23a transmits the signal, and the three OR circuits 36, 37, 3
8 each sends a message.

In response to the transmission of the OR circuit 36, the stop signal section 43b transmits the signal, the screw conveyor 15 stops, and the OR circuit 3
7 causes the alarm signal section 45a to issue an alarm, and the output signal of the NOT circuit 39 is stopped.Furthermore, the OR circuit 38 causes the shutter 5 to close, and the close signal section 21b issues an alarm.

In this state, in order to eliminate the bridging phenomenon, the inspection port 9
When the lid body 10 is opened, the open signal section 24a sends a signal,
Subsequently, when the bridge phenomenon is canceled, the cancellation signal section 23b
transmits, and the AND circuit 30 transmits.

The signal causes the output signal of the knot circuit 40 to stop, while the alarm release signal section 45b sends the signal to stop the alarm, and the AND circuit 33 sends the signal to stop the output signal of the knot circuit 41. The signal is input to the closing signal section 24b.

Thereafter, when the lid body 10 is closed, the closing signal section 24b issues a signal, and the normal operation as described above is repeated.

Next, when the container 12 becomes full, the state is detected by the overcurrent of the drive motor 16, and the full signal section 46a sends a signal, which causes the three OR circuits 36, 37 to be transmitted.

38 each make a call.

In response to the transmission of the OR circuit 36, the stop signal section 43b transmits the signal, the screw conveyor 15 stops, and the OR circuit 3
7 causes the alarm signal section 45a to issue an alarm, and the output signal of the NOT circuit 39 is stopped.Furthermore, the OR circuit 38 causes the shutter 5 to close, and the close signal section 21b issues an alarm.

Subsequently, the screw conveyor stop signal section 43b
, the AND circuit 31 generates a signal based on the output signals of the alarm signal section 45a and the NOT circuit 40, while the AND circuit 35 generates a signal based on the output signal of the shutter closing signal section 21b and the NOT circuit 41, and the AND circuit 34 generates a signal.

When the container 12 is removed from the compactor 11 due to the full warning, the alarm release signal unit 45b issues a signal from the AND circuit 34, the alarm is stopped, and the removal signal unit 25b issues the alarm.

When the empty container 12 is connected again, the above operation can be repeated.

As described above, according to the present invention, since the dust detection device is provided at one location in the dust chute, there is no need to provide opening/closing detection means for each floor input port as in the past, and the wiring and control mechanism are simplified. Furthermore, since the flow of garbage is directly detected, it is possible to prevent the garbage processing device from being driven due to erroneous operation.

Furthermore, we have installed a radio-wave dust detection device that utilizes the Doppler effect of microwaves, so it operates reliably without malfunctions due to fogging on the glass surface, as with phototube detection, or malfunctions due to factors other than dust, as with sound wave detection. Detect.
