In this state, when the waste is inserted as it is from the insertion port or in a state where it is put in an individual container (S101), the inserted waste is transferred to the measuring table located immediately below the insertion port. Placed on top, the weight of the waste and its bulkiness are measured (S102),
The measured values are displayed on the display 201 (FIG. 3) of the operation panel 102 (S103). At this time, if the bulk of the newly inserted waste is higher than the remaining allowable bulk of the waste already contained in the bag, the input of the waste is refused, This is displayed on the display of the operation panel 102 or warned by a warning sound such as a buzzer. Further, the measured weight is accumulated to the previous weight value, and the total weight of the waste currently contained in the bag is measured and displayed on the display of the operation panel.

In addition, a liquid leak detector for detecting a liquid leak from the bag is provided below the bag.
If liquid leakage from the bag is detected (S104), a display or warning is given to that effect (S105).

When the weight or bulkiness of the waste put in one bag in this way exceeds a predetermined value, the bags are automatically bound (S106). The bags thus bound are moved in the direction of the discharge port by the rotation of the roller (S107).
The moving position is displayed on the display of the operation panel.

By switching the rotation of 317 with a clutch (not shown),
Each can be performed independently. Thus, even if the bag 107 is set at a position where waste can be received, the rotation of the roller 105 causes the bag 107 to rotate.
Only the bags 107 located at b to 107d can be moved in the discharging direction and discharged.

Next, the processing of the control unit 300 of the waste collection apparatus 100 according to the present embodiment will be described with reference to the flowcharts of FIGS. It should be noted that a control program for executing this processing is stored in the program memory 322 and is executed under the control of the CPU 321.

First, in step S1, initialization of various data in the RAM 323, the display 201, the LED2
Initialization of displays such as 08 to 212 is performed. At this time, if the bag is not set in the slot 101, the suction unit 4
05 of the bag suspended and held by the bag holding unit by 05
One is sucked, moved to a position where waste can be received, and set, so that the bag can receive waste. Next, the process proceeds to step S2, and it is determined whether the closing door open / close switch 206 of the operation panel 102 has been pressed.
When the door open / close switch 206 is pressed, the process proceeds to step S3.
To check whether the slot 101 is open. This can be confirmed by providing a flag in the RAM 323 for storing the open / closed state of the door 401a.
If the slot 101 is open in step S3, the process proceeds to step S4, in which the opening / closing motor 313 is driven to open the door 40.
The insertion port 101 is closed by 1a, and the process returns to step S2. At this time, the flag is simultaneously set to the closed state.

On the other hand, when the insertion port 101 is closed in step S3, the process proceeds to step S5, where the opening / closing motor 313 is opened.
Is driven to open the door 401a (set the flag to the open state), and in step S6, it is checked whether or not waste is put into the insertion port 101. This can be confirmed by weight detection by the input photoelectric switch 301 and / or the measuring table 402. When the waste is put in this way, the process proceeds to step S7, and the weight and bulkiness of the put waste (individual container) are measured. In step S8, when the waste is put into the bag 107, it is checked whether any of the total weight and the bulkiness of the bag does not exceed the reference value (allowable amount). Proceed and warn of that
Display and reject the waste input.

In this embodiment, the total weight of the waste is up to about 20 kg, and the allowable bulk is about 70 kg of the height of the bag.
%.

In step S9, if it is determined that both the weight and bulkiness are within the allowable values even if the waste is thrown in, the process proceeds to step S10, in which the opening / closing motor 313 is rotationally driven to rotate the cylinder including the door 401a. The entire part 401 is moved in the bag direction (the door 401a is closed). Thereby, the measuring table 4
The waste placed on the bag 02 is moved in the bag direction, and the placed waste is dropped into the bag 107. Thus, the insertion port 101 is in a closed state. Next, the weight measured in step S7 is added to the previous weight value (weight memory) and stored in the weight memory of the RAM 323, and the value is displayed on 204 of the display 201. Also,
The bulk of the waste put into the bag 107 is detected by the four sets of photoelectric switches 302, and the display 201 is displayed.
(Step S12). Step S1
In 3, it is determined whether or not a liquid leak has occurred from the bag 107.
Judgment is made based on the signal from the leak detector 304. If a leak has occurred, the process proceeds to step S14, where the leak LE
D210 is turned on, and step S16 is performed to bind the bags.
Proceed to.

On the other hand, if no liquid leakage has occurred, the flow advances to step S15 to determine whether or not the bags 107 are to be bound. This criterion is based on a total weight of 20.
It is checked whether the Kg has reached 90% or more of Kg (18 Kg), and it is determined whether the bulk has reached about 80% or more of the allowable height. If it is determined that the binding should be performed, the process proceeds to step S16 to perform the binding process. If not, the process returns to step S2 and proceeds to the process of detecting whether the switch on the operation panel 102 has been pressed.

In step S16, as described above, the roller 107 is rotated to move the bag 107 before binding slightly to the binding portion 108 side, and the binding motor 316 is driven to bind the bag 107. Although omitted in this flowchart, at this time, if the sensor 306 detects that there is no remaining binding member, the fact is displayed on the display 201 and the error LED 212 is lit,
After the binding members have been replenished, the processing from step S16 is performed.

In step S17, the bound bag 10
It is checked whether there is a free space in the waiting space for waiting for No. 7. If there is a space, the process proceeds to step S18, in which the discharge motor 317 is driven to move the bag 107 toward the discharge port and wait. The display 205 on the display 201 is changed accordingly. Next, in step S19, the bulkiness displayed so far is changed, the content of the weight memory is cleared to "0", and the weight display 205 becomes "0".

Next, the process proceeds to step S20, where the next bag 107 is
Is set, the number of remaining bags 107 suspended on the back of the door 103 is checked. If there is a spare bag 107, the process proceeds to step S24, and as described above, the suction unit 40 is set.
5, the bag 107 is sucked by the hopper 404.
07 is opened and fixed.
The remaining number of bags stored in 3 is decremented by one. If there is no remaining bag, the process proceeds to step S21, the LED 211 indicating that there is no remaining bag is turned on, and in step S22, the process waits until the bag is refilled. This bag replenishment may be detected by opening and closing the door 103, or may be determined based on whether the number of bags is newly set from the operation panel 102. When the bags 107 are refilled in this way, the process proceeds to step S23, where the number of new bags is displayed on the display 201,
The LED 211 is turned off. Then, the process proceeds to step S24.

On the other hand, if the standby space is full in step S17, the process proceeds to step S25, and a warning is displayed on the display 201, and in step S26, the discharge instruction switch 207 is pressed by the operator to stand by. It is determined whether or not an instruction to discharge the bound bags 107 has been issued, and if so, the process proceeds to step S27,
It is determined whether or not the discharge door 104 is open. If not, the process proceeds to step S28, and the fact is displayed on the display 201 and the error LED 212 is turned on. still,
The opening / closing of the door 104 is detected by a door opening / closing sensor 305.

When the door 104 is opened and the bound bags 107 can be discharged in this manner, the process proceeds to step S29, in which the discharge roller 317 is driven to rotate by the discharge motor 317, and the bags are discharged from the bag closest to the discharge port. The display 205 of the display 201 is also changed in accordance with the discharging process.

If it is determined in step S2 in FIG. 11 that the open / close switch 206 is not pressed, step S30 (FIG. 13)

The process proceeds to step S31, where it is checked whether the door 104 is open as in step S27 described above.
Similarly, the roller roller 105 is driven to rotate, and the bag closest to the discharge port is discharged. When the door 104 is not opened, the process proceeds to step S32, and a warning display or the like is performed as in step S28.

In step S33, the discharge instruction switch 2
If No. 07 is not turned on, the flow proceeds to step S33, where it is checked whether or not a liquid leak has occurred by the liquid leak detector 304. If a leak has occurred, the flow proceeds to step S34 and the LED 21
0 is lit to notify the occurrence of liquid leakage, and step S34
Then, the electromagnetic valve 307 is operated, the leaked liquid is transferred to the collection container 406, and the process proceeds to step S16 to bind the bags. If no liquid leakage is detected in step S33, the process returns to step S2 to detect whether the switch has been operated as described above and perform the processing.

As described above, according to the waste recovery apparatus 100 of the present embodiment, the waste is stored in the bag simply by putting the waste therein, and when the predetermined amount of waste is stored in the bag, the binding is automatically performed. And dispose of the whole bag. Therefore, there is an effect that the waste can be easily discarded without soiling the hands.

Further, according to the present embodiment, since the waste is stored in a sealed state, the waste can be stored and bound in a bag without the odor leaking outside and without the intervention of human hands. Therefore, it is possible to prevent the transmission of pathogenic bacteria to humans from the waste.

Since little power is consumed except at the time of disposal and when the bag is discharged, the running cost can be kept low.
