Will be described. As shown in FIG. 6, the rod 22 of the flapper supporting solenoid 20 advances in advance, the flapper 14 is held in a horizontal state by the pin 23 as shown in FIG. 5A, and the flapper driving solenoid 16 is turned off. It is working. In this state, as shown in FIG. 1, the handle 8 of the door member 5 is gripped, the door member 5 is opened, and the opened waste insertion port 4 is made of PET.
When the bottle 10 is inserted into the reverse insertion restricting member 11 from the normal direction, that is, from the side of the drinking mouth 10c, the PET bottle 10 is fitted to the reverse insertion restricting member 11, as shown in FIG. Therefore, the bottom 10a of the PET bottle 10
3 does not protrude from the waste insertion port 4, and FIG.
As shown in FIG. 5, the door member 5 closes the waste insertion slot 4, so that the contact point of the microswitch 9 is pressed by the hinge member 6, and an ON signal is output. Further, an ON signal is output from the first proximity sensor 36 and the second proximity sensor 37 when a portion having a predetermined height of the body 10b of the PET bottle 10 approaches.

Micro switch 9, first proximity sensor 36
In response to the output of the ON signal from the second proximity sensor 37 and the control unit 60, the control unit 60 controls the rotary blade drive motor 48 to rotate the rotary blades 39 and 40, and controls the flapper supporting solenoid 20 to control the rod. By retreating the pin 22, the pin 23 moves in the direction of arrow A in FIG. 6, the support of the flapper 14 is released, and the pin 23 hangs obliquely downward by the weight of the flapper 14 as shown by a two-dot chain line in FIG. I do. Therefore, the lower part of the reverse insertion restricting member 11 is opened, and the PET bottle 10 slides down on the flapper 14 from inside the reverse insertion restricting member 11 and falls down inside the hopper 13, so that the rotating rotary blades 39, 40.

When the PET bottle 10 is sent to the rotary blades 39 and 40, the flapper 14 swings downward about the shaft 15 on the side opposite to the drinking port 10c of the PET bottle 10, ie, the shaft 15 on the waste insertion port 4 side. As it moves, PET bottle 1
0 falls with the drinking spout 10c side directed downward, so that the drinking spout 10c reliably bites the rotary blades 39 and 40, and the PET bottle 10 is crushed by the rotary blades 39 and 40. Pieces of the PET bottle 10 generated by being crushed by the rotary blades 39 and 40 are stored in the storage section 51.

Next, as shown in FIG. 4 (a), when the PET bottle 10 is inserted into the waste insertion port 4 in the reverse direction, that is, from the bottom 10a of the PET bottle 10 to the waste insertion port 4. When inserted, the bottom 10a is locked to the tapered portion 11b of the reverse insertion restricting member 11, so that the drinking port 10c
Project from the waste insertion port 4. Therefore, FIG.
As shown in (b), the door member 5 is connected to the drinking spout 10c.
Can not close the waste insertion slot 4
The contact of the microswitch 9 is not pressed by the hinge member 6, and the microswitch 9 outputs an OFF signal. For this reason, in FIG. 6, the flapper supporting solenoid 20 does not operate, and the state in which the flapper 14 is supported by the pin 23 is maintained.
The PET bottle 10 in the reverse insertion regulating member 11 is
It does not fall to 9,40.

Further, the door member 5 is opened by grasping the handle 8 of the door member 5 and the PET bottle 1 is inserted into the opened waste insertion port 4.
When the PET bottle 10 is inserted into the reverse insertion restricting member 11 from a normal direction, and the inserted PET bottle 10 is subsequently removed from the reverse insertion restricting member 11, the first proximity sensor 36 and the second proximity sensor 37 turn OFF. A signal is output. For this reason, in FIG. 6, the flapper supporting solenoid 20 does not operate, and the state in which the flapper 14 is supported by the pin 23 is maintained.
A foreign object such as a string, a net, a slender or flexible object such as a thermosetting plastic, or a foreign object such as a thick metal plate and the PET bottle 10 are inserted at the same time.
When only the PET bottle 10 is taken out after the above-described foreign matter is inserted in a state where is inserted, the foreign matter remaining in the reverse insertion restricting member 11 is removed by the rotary blades 39 and 40.
Never fall.

Further, even when the above-described foreign matter is erroneously inserted from the waste insertion slot 4, the OFF signal is output from the first proximity sensor 36 and the second proximity sensor 37. For this reason, in FIG. 6, the flapper support solenoid 20 is not operated and the flapper 14 is supported by the pin 23, so that the foreign matter in the reverse insertion restricting member 11 falls on the rotary blades 39, 40. I will not do it.

As described above, according to the first embodiment,
The first proximity sensor 36 and the second proximity sensor 37 are provided, and the control unit 60 (the crushing control unit 65) controls the PET bottle 1 in the first proximity sensor 36 and the second proximity sensor 37.
The PET bottle 10 is inserted or removed based on the detection order of 0, and when it is determined that the PET bottle 10 is inserted, the PET bottle 10 is rotated by the rotary blades 39 and 40.
When the PET bottle 10 is inserted, the support of the lower end of the flapper 14 by the pin 23 is released, and the PET bottle 10 is moved to the rotary blades 39 and 40. Sent out,
The PET bottle 10 can be reliably crushed. On the other hand, when the control unit unit 60 (crush control unit 65) determines that the PET bottle 10 has been removed based on the detection order of the PET bottle 10 by the first proximity sensor 36 and the second proximity sensor 37, the flapper supporting solenoid 2
0 is not actuated and the PET bottle 10 is not sent out to the rotary blades 39, 40, so that the PET bottle 10 is inserted after the PET bottle 10 and the foreign matter are inserted at the same time.
Even if only foreign matter is removed and foreign matter remains,
Foreign matter is not sent to the rotary blades 39 and 40, and crushing of the foreign matter can be reliably prevented. In addition, the micro switch 9 is provided, and the control unit 60 (crush control unit 65)
Does not operate the flapper supporting solenoid 20 even when the door member 5 is in the open state, so that the inserted PE
Even when the door member 5 is opened to take out the T bottle 10, foreign matter is not sent to the rotary blades 39 and 40, and crushing of the foreign matter can be more reliably prevented.

The first proximity sensor 36 and the second proximity sensor 37 are provided at a predetermined height of the PET bottle 10 (in the first embodiment, the PET bottle 10 is
4 and supported by a predetermined position on the flapper 14 so as to be in a standby state.
When b) approaches, an ON signal is output and the PET bottle 10
Outputs an OFF signal when is not in close proximity.
When a foreign substance such as a rod-shaped metal, a wire, a string, a net, a thermosetting plastic, or a foreign substance such as a thin or flexible substance, or a foreign substance such as a thick metal plate is erroneously inserted from the waste insertion port 4. In addition, it is possible to prevent these foreign substances from being erroneously detected as the PET bottle 10.

When the PET bottle 10 is inserted into the reverse insertion restricting member 11 from the normal direction, that is, from the side of the drinking mouth 10c, the PET bottle 10 fits into the reverse insertion restricting member 11, so that the bottom 10a of the PET bottle 10 is Can be closed by the door member 5 without projecting from the waste insertion port 4. On the other hand, the PET bottle 10 is
When inserted into the reverse insertion restricting member 11 from the side a, the bottom 10
Since a is locked by the tapered portion 11b of the reverse insertion restricting member 11, the drinking port 10c of the PET bottle 10 projects from the waste insertion port 4, and the waste insertion port 4 cannot be closed by the door member 5. . Therefore, PET bottle 10
Is inserted into the reverse insertion restricting member 11 from the bottom 10a side, the door member 5 is not closed, so that the ON signal is not output from the microswitch 9, and the control unit 60 is driven by the flapper. The solenoid 16, the flapper supporting solenoid 20, the rotary blade drive motor 48 and the like are not operated. On the other hand, when the PET bottle 10 is inserted into the reverse insertion restricting member 11 from the drinking spout 10c side, the door member 5 can be closed. Therefore, when the door member 5 is closed, an ON signal is output from the microswitch 9. That is, the output of the ON signal from the microswitch 9, the first proximity sensor 36, and the second proximity sensor 37 causes the control unit 60 to control the flapper drive solenoid 16, the flapper support solenoid 20, the rotary blade drive motor 48, and the like. Will be activated. As a result, the PET bottle 10 having a tapered tip can be guided to the rotary blades 39 and 40 from the drinking spout 10c side without fail, and the P bottle in the rotary blades 39 and 40 can be provided without newly providing a pushing means or the like.
The ability of the ET bottle 10 to bite into the spout 10c is improved, the PET bottle 10 can be crushed reliably, and the device can be reduced in size, the number of parts can be reduced, and the cost can be reduced.

The PE inserted from the waste insertion port 4
By having a flapper 14 for temporarily supporting the T bottle 10 and a pin 23 for supporting the lower end of the flapper 14, by operating the flapper support solenoid 20 to release the support of the lower end of the flapper 14 by the pin 23, Flapper 1
4 and the PET bottle 10 waiting on the rotating blades 39, 4
Since the PET bottle 10 is sent toward 0, a configuration capable of reliably sending the PET bottle 10 to the rotary blades 39 and 40 can be realized simply and at low cost.

The PET bottle 10 has rotating blades 39, 4
0, the spout 10c of the PET bottle 10
The flapper 14 swings downward around the shaft 15 on the opposite side, that is, the shaft 15 on the waste insertion port 4 side, so that the PET bottle 10 can be surely dropped with the drinking port 10c side directed downward. Become. As a result, the PET bottle 10 having a tapered tip is inserted into the rotating blade 3 from the drinking spout 10c side.
9 and 40, and the PE in the rotary blades 39 and 40 can be provided without newly providing a pushing means or the like.
The biting property of the T bottle 10 to the drinking mouth 10c is improved,
The PET bottle 10 can be reliably crushed, and the device can be reduced in size, the number of parts can be reduced, and the cost can be reduced.

Further, the fact that the PET bottle 10 has been inserted into the reverse insertion restricting member 11 from the side of the drinking mouth 10c is detected by the hinge member 6 pressing the contact of the microswitch 9 when the door member 5 is closed. As means for detecting that the PET bottle 10 is inserted in the normal direction by the reverse insertion restricting member 11 and that the insertion direction of the PET bottle 10 is regulated by the reverse insertion restricting member 11, waste insertion is performed. Since the door member 5 that opens and closes the mouth 4 is also used, the number of parts can be reduced.

The flapper 14 is used for the PET bottle 10
By pivoting downward about the shaft 15 on the side opposite to the drinking port 10c, that is, on the side of the waste insertion port 4,
The ET bottle 10 falls with the drinking spout 10c facing downward, and the PET bottle 10 is
A configuration that can reliably send the data to 0 can be realized simply and at low cost.

Further, the opposed portion F of the rotary blades 39 and 40
The distance L between the point and the lower end of the hanging flapper 14 is PET.
Since it is set slightly longer than the total length of the bottle 10,
Since the bottom 10a of the PET bottle 10 in which the drinking mouth 10c has dropped to the point F is separated from the flapper 14, the hopper 1
3 falls into the guide portion 13a. Accordingly, the guide portion 13a guides the PET bottle 10 to the point F where the rotary blades 39 and 40 face each other, so that the PET bottle 10 securely bites from the drinking spout 10c to the rotary blades 39 and 40, so that the biting property is reduced. It can be further improved.

Next, a modification of the waste crushing operation performed by the control unit 60 (crush control unit 65) included in the first embodiment will be described with reference to FIG. FIG.
The waste crushing operation shown in FIG. 4 differs from the waste crushing operation shown in FIG. 11 in that the insertion flag is not used.

First, in S401, the first
Based on the detection output from the proximity sensor 36, it is determined whether or not the body 10b of the PET bottle 10 is in proximity to the first proximity sensor 36. When the detection output from the first proximity sensor 36 is “ON”, the body 10 b of the PET bottle 10 is

Causes the rod 22 to retract, the pin 23 withdraws from the inside of the hopper 13, the support of the lower end of the flapper 14 by the pin 23 is released, and the flapper 14 swings clockwise in FIG. Then, the PET bottle 10 placed on the flapper 14 is sent out toward the rotary blades 39 and 40.

At S409, the flapper supporting solenoid 20
After the control signal is output to step S411, when the bottom of the PET bottle 10 is separated from the lower end of the hanging flapper 14, this is detected by a detection unit (not shown),
A control signal is output to the flapper drive solenoid 16 so as to make the flapper 14 horizontal. As a result, the flapper driving solenoid 16 retreats the rod 17, the flapper 14 swings counterclockwise in FIG. 5A around the shaft 15 as the swing center, and is brought into a horizontal state, and the opening of the reverse insertion regulating member 11 is opened. Will be located below.

Thereafter, the flow advances to S413, where a control signal is output to the flapper supporting solenoid 20 so as to support the flapper 14 which is in a horizontal state. Thereby, the flapper supporting solenoid 20 advances the rod 22, the pin 23 advances into the hopper 13 from the fitting hole 13c, the lower end of the flapper 14 is supported by the pin 23, and the flapper 14 is held in a horizontal state. Become. When the detection output from the first proximity sensor 36 is “OFF” (“N” in S401)

Further, the first proximity sensor 36 and the second proximity sensor 37 are provided at a predetermined height of the PET bottle 10 (in the first embodiment, the PET bottle 10 is
4 and supported by a predetermined position on the flapper 14 so as to be in a standby state.
When b) approaches, an ON signal is output and the PET bottle 10
Outputs an OFF signal when is not in close proximity.
When a foreign substance such as a rod-shaped metal, a wire, a string, a net, a thermosetting plastic or the like, which is a slender or flexible substance, or a foreign substance such as a thick metal plate is erroneously inserted from the waste insertion port 4, In the case where only the PET bottle 10 is removed after the foreign matter and the PET bottle 10 are inserted at the same time, the control unit unit 60 (crushing control unit 65) does not erroneously detect these foreign matter as the PET bottle 10. As a result, the foreign matter is not sent to the rotary blades 39 and 40, and crushing of the foreign matter can be reliably prevented.

In the present modification, the control unit 60 (crushing control unit 65) inserts the PET bottle 10 based on the detection order of the PET bottle 10 by the first proximity sensor 36 and the second proximity sensor 37. Alternatively, the removal of the PET bottle 10 has not been determined, but since the first proximity sensor 36 and the second proximity sensor 37 are disposed at different positions in the insertion direction of the PET bottle 10, the insertion of the PET bottle 10 is reliably detected. can do.

(Second Embodiment) A waste treatment apparatus according to a second embodiment of the present invention will be described with reference to FIGS. Waste treatment apparatus 10 according to second embodiment
1 is different from the waste disposal apparatus 1 in the first embodiment with respect to the proximity sensor.

The operation is controlled based on each control signal.

The crushing control section 165 reads the output from the microswitch 9 and the proximity sensor 136 every predetermined cycle, and performs the waste crushing operation shown in FIG. First, in S501, the proximity sensor 136 is read based on the detected output from the proximity sensor 136.
Then, it is determined whether or not the body 10b of the PET bottle 10 is in a close state. If the detection output from the proximity sensor 136 is “ON” and the body 10b of the PET bottle 10 is in the proximity state (“Yes” in S501), the process proceeds to S50.
Proceed to 3. When the detection output from the proximity sensor 136 is “OF
In the case of "F", if the body 10b of the PET bottle 10 is not in proximity ("No" in S501), the process proceeds to S511 described later.

Then, the PET bottle 10 placed on the flapper 14 is sent out toward the rotary blades 39 and 40.

At S507, the flapper supporting solenoid 20
After the control signal is output to step S509, when the bottom of the PET bottle 10 is separated from the lower end of the hanging flapper 14, this is detected by a detection unit (not shown),
A control signal is output to the flapper drive solenoid 16 so as to make the flapper 14 horizontal. As a result, the flapper drive solenoid 16 retreats the rod 17, the flapper 14 swings about the shaft 15 as a swing center, and is brought into a horizontal state, and is located below the opening of the reverse insertion regulating member 11.

Thereafter, the flow advances to S511, where a control signal is output to the flapper supporting solenoid 20 so as to support the flapper 14 which is in a horizontal state. Thereby, the flapper supporting solenoid 20 advances the rod 22, the pin 23 advances into the hopper 13 from the fitting hole 13c, the lower end of the flapper 14 is supported by the pin 23, and the flapper 14 is held in a horizontal state.
