DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a waste disposal apparatus for crushing waste such as empty cans or empty bottles.

[0002]

2. Description of the Related Art This type of waste treatment apparatus usually has a waste insertion port into which waste is inserted, a crushing blade as crushing means, and the like. The material is crushed by the crushing blade.

[0003]

In the above-described waste treatment apparatus, a slender or soft foreign substance such as a rod-shaped metal, a wire, a string, a net, and a thermosetting plastic is erroneously inserted from the waste insertion port. When inserted in such a manner, there is a concern that these foreign substances may cling to the crushing blade and cause a failure of the apparatus. Further, when a foreign substance such as a thick metal plate is erroneously inserted from the waste insertion port, the crushing blade may be damaged by the foreign substance.

[0004] The present invention has been made in view of the above-mentioned points, and in the case where a foreign substance not to be treated is erroneously inserted, crushing of the foreign substance is prevented, and waste such as an empty can or an empty bottle is inserted. In such a case, an object of the present invention is to provide a waste disposal apparatus capable of reliably crushing waste.

SUMMARY OF THE INVENTION A waste disposal apparatus according to the present invention is a waste disposal apparatus for crushing waste such as empty cans or empty bottles, comprising: a waste insertion opening into which waste is inserted; A door member for opening and closing the waste insertion opening, crushing means for crushing the waste, standby means for waiting the waste inserted from the waste insertion opening at a predetermined standby position, and waste material at a predetermined standby position Sending means for sending out to the crushing means,
First detecting means for detecting that the waste has been inserted to the predetermined standby position, and the first detecting means are provided at a predetermined interval in the direction of insertion of the waste and detect the presence or absence of the waste. A second detection unit, a third detection unit that detects an open / closed state of the door member, and a first detection unit that detects that the waste has been inserted to a predetermined standby position, and the second detection unit has a function of discarding the waste. Control means for controlling the operation of the sending means so as to send the waste toward the crushing means when the third detecting means detects that the door member is in the closed state in a state where the object is being detected; , Are provided.

In the waste disposal apparatus according to the present invention, a standby unit for waiting the waste inserted from the waste insertion port at a predetermined standby position, and sending the waste at the predetermined standby position toward the crushing unit. Sending means, a first detecting means for detecting that the waste is inserted to a predetermined standby position, and a first detecting means provided at a predetermined interval in a waste inserting direction, A second detecting means for detecting the presence or absence of the door, and a third detecting means for detecting the open / closed state of the door member, wherein the first detecting means detects that the waste is inserted to a predetermined standby position, and When the third detecting means detects that the door member is in the closed state while the second detecting means is detecting waste, the control means sends the waste toward the crushing means. Since the operation of the sending means is controlled, empty cans or empty bottles, etc. If the waste has been inserted can be waste is delivered to the crushing unit, crushing reliably waste. On the other hand, when a foreign object such as a stick-shaped metal, a wire, a string, a net, a thin or flexible object such as a thermosetting plastic, or a foreign object such as a thick metal plate is mistakenly inserted from the waste insertion slot, or If the door member is opened after the waste and the foreign matter are inserted at the same time and only the waste is taken out and the foreign matter remains, the control means sends the waste toward the crushing means. And these foreign substances are not sent to the crushing means. In particular,
Since the first detecting means and the second detecting means are provided at a predetermined interval in the direction of inserting the waste, the length of the waiting waste in the inserting direction can be detected, and the above-described foreign matter can be detected. And the waste can be reliably detected. As a result, it is possible to prevent the foreign matter from being crushed when a foreign matter that is not to be processed is erroneously inserted.

[0007] Further, the first detecting means and the second detecting means,
It is preferable to be provided with a predetermined interval in the up-down direction when viewed from the waste insertion direction. In the case of such a configuration, the first detection means and the second detection means detect different portions in the vertical direction of the waste when viewed from the insertion direction of the waste, and the waste disposed in a standby state. The waste can be detected in the height direction of the object, and the waste can be more reliably detected in distinction from the above-described foreign matter.

The waiting means has a support means for temporarily supporting the waste inserted from the waste insertion port, and the sending means has a release means for releasing the support of the waste by the support means. Preferably, the control means controls the operation of the release means so as to release the bearing of the waste. With such a configuration, a configuration capable of reliably sending waste to the crushing means can be realized simply and at low cost.

An insertion direction defining means which is formed in a tapered shape as viewed in the direction of insertion of the waste and is fitted to one end of the waste inserted from the waste insertion opening to define the insertion direction of the waste. Preferably, the first detecting means detects that one end side of the waste is fitted to the insertion direction defining means. As described above, the so-called PET bottle having a tapered tip is provided by the insertion direction defining means that is fitted to one end side of the waste inserted from the waste insertion opening and defines the insertion direction of the waste. And the like can be reliably guided from the front end side to the crushing means. As a result, the biting ability of the crushing means into the empty bottle is improved without newly providing a means for pushing waste, etc., and the empty bottle can be reliably crushed, and the size of the apparatus is reduced and the number of parts is reduced. In addition, the cost can be reduced. Further, since the first detecting means detects that one end of the waste is fitted to the insertion direction defining means, it is possible to reliably detect that the waste is inserted to the predetermined standby position.

The crushing control unit 65 includes a micro switch 9, a proximity sensor 35, and a reflection type sensor 3 at predetermined cycles.
6 is read, and the waste crushing operation shown in FIG. 9 is performed.

First, in step S101, based on the detected output from the proximity sensor 35, the proximity sensor 35
Then, it is determined whether or not the drinking mouth 10c of the PET bottle 10 is in the proximity state. The state in which the detection output from the first proximity sensor 35 is “ON” and the drinking port 10 c of the PET bottle 10 is in proximity, that is, the drinking port 10 c of the PET bottle 10
Is inserted into the narrow portion 11c (S1).
01 (“Yes”), the process proceeds to S103. Proximity sensor 35
If the detection output from the PET bottle 10 is “OFF” and the drinking port 10 c of the PET bottle 10 is not in proximity (S 1
01 (“No”), the process proceeds to S113 described below.

In S103, the read reflection type sensor 3
6, it is determined whether or not an object (the body 10b of the PET bottle 10) exists at the position where the reflection type sensor 36 is disposed. When the detection output from the reflective sensor 36 is “OFF” and the object (the body 10b of the PET bottle 10) is present at the position where the reflective sensor 36 is disposed (“Yes” in S103). ), PET
It is determined that the bottle 10 has been inserted, and the process proceeds to S105. When the detection output from the reflection sensor 36 is “ON”, the object (the body 10 of the PET bottle 10)
If b) does not exist (“No” in S103), the process proceeds to S113 described below.

In S105, it is determined whether or not the door member 5 is in a closed state based on the detected output from the microswitch 9. When the detection output from the micro switch 9 is “ON” and the door member 5 is in the closed state (S
"Yes" in 105), the process proceeds to S107, and the rotary blade 39,
A control signal is output to the rotary blade drive motor 48 so as to rotate 40. The detection output from the micro switch 9 is "O
FF ", if the door member 5 is open (S105
The process proceeds to S113 described later.

At S109, a control signal is output to the flapper supporting solenoid 20 so as to release the support of the flapper 14. Thereby, the flapper supporting solenoid 20
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 S109, the flapper supporting solenoid 20
After the control signal is output to step S111, 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 process proceeds to S113, 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 proximity sensor 35 is “OFF” (“No” in S101),
When the detection output from the reflection sensor 36 is “ON” (“No” in S103) or when the door member 5 is open (“No” in S105), this S113 is performed.
The flapper 14 is held in a horizontal state, and the PET bottle 10 and the like placed on the flapper 14
It is not sent to 9,40.

The rotation of the rotary blade drive motor 48 is configured to stop after a predetermined time has elapsed from the start of rotation by using a timer. Until the cutting of the sent PET bottle 10 is completed (the rotation of the rotary blade drive motor 48 is stopped), the next PET bottle 1 is cut.
Even if 0 is inserted into the reverse insertion restricting member 11 in a normal direction, the flapper supporting solenoid 20 may be controlled so that the pin 23 does not leave the hopper 13.

Next, the waste disposal apparatus 1 having such a configuration will be described.
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 in a normal direction, that is, from the side of the drinking port 10c, the drinking port 10c of the PET bottle 10 is narrowed as shown in FIG. It fits into the part 11c. Therefore,
Since the bottom portion 10a of the PET bottle 10 does not protrude from the waste insertion slot 4 and the door member 5 closes the waste insertion slot 4 as shown in FIG. Is pressed, and an ON signal is output. The proximity sensor 35 outputs an ON signal when the drinking mouth 10c fitted in the narrow portion 11c of the reverse insertion regulating member 11 approaches. Further, from the reflection type sensor 36, P
Due to the presence of the ET bottle 10 (body 10b),
An OFF signal is output.

In response to the output of the microswitch 9, the ON signal from the proximity sensor 35 and the OFF signal from the reflection sensor 36, the control unit 60 causes the rotary blade drive motor 4
8 to rotate the rotary blades 39 and 40 and the flapper support solenoid 20 to retract the rod 22, the pin 23 moves in the direction of arrow A in FIG. The flapper 14 is released and hangs obliquely downward by the weight of the flapper 14 as shown by a two-dot chain line in FIG. 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
The rotating 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, that is, 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. 4A, when the PET bottle 10 is inserted into the waste insertion slot 4 in the opposite direction, that is, from the bottom 10a of the PET bottle 10 to the waste insertion slot 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. Further, from the proximity sensor 35, the drinking mouth 10c fitted into the narrow portion 11c of the reverse insertion regulating member 11
Are not close to each other, an OFF 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, so that the PET bottle 10 in the reverse insertion restricting member 11 is rotated by the rotary blades 39 and 40. Never fall.

In addition, a foreign substance such as a rod-shaped metal, a wire, a string, a net, a thermosetting plastic, or a slender or flexible substance, or a foreign substance such as a thick metal plate is erroneously inserted into the waste insertion port 4. Even when inserted, the proximity sensor 35
FF signal is output or ON from reflection sensor 36
A signal is output. For this reason, the flapper support solenoid 20 does not operate, and the state in which the flapper 14 is supported by the pins 23 is maintained, so that the foreign matter in the reverse insertion restricting member 11 does not fall on the rotary blades 39, 40. .

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.
0 is inserted into the reverse insertion restricting member 11 from a normal direction, and when the inserted PET bottle 10 is removed from the reverse insertion restricting member 11, the foreign matter and the PET bottle 10 are simultaneously inserted as described above, Alternatively, even when only the PET bottle 10 is removed after the above-described foreign matter is inserted with the PET bottle 10 inserted, an OFF signal is output from the proximity sensor 35, or an ON signal is output from the reflection sensor 36. A signal is output. For this reason, the flapper support solenoid 20 does not operate, and the state in which the flapper 14 is supported by the pin 23 is maintained.
Foreign matter remaining in the reverse insertion restricting member 11
It does not fall to 40.

Further, a PET cut from an intermediate portion of the body 10b except for the drinking port 10c and the tapered portion 10d.
When the bottle is inserted, from the proximity sensor 35,
An ON signal is output when the drinking spout 10c fitted in the narrow portion 11c of the reverse insertion restricting member 11 approaches, but the PET sensor 10 is output from the reflective sensor 36 to the position where the reflective sensor 36 is disposed. Since the (body part 10b) does not exist, an ON signal is output. For this reason, the flapper support solenoid 20 does not operate, and the flapper 14 is supported by the pins 23, so that the PET bottle having the above-mentioned shape does not fall on the rotary blades 39, 40.

As described above, according to the present embodiment, the microswitch 9, the proximity sensor 35, and the reflection sensor 36
And the control unit 60 (crushing control unit 65) controls the proximity sensor 35 based on the detection signals from the microswitch 9, the proximity sensor 35, and the reflection type sensor 36.
Is close to the drinking spout 10c of the PET bottle 10 inserted from the waste insertion opening 4 (the drinking spout 10c has been inserted to a predetermined standby position fitted into the narrow portion 11c of the reverse insertion restricting member 11). When the micro switch 9 detects that the door member 5 is in the closed state while the reflective sensor 36 detects the presence of the object (the body 10b of the PET bottle 10), PET bottle 10
The flapper supporting solenoid 20 is controlled so that the PET bottle 10 is sent toward the rotary blades 39 and 40. Therefore, 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 Rotating blade 39,
The PET bottle 10 can be reliably crushed.

On the other hand, a slender or soft foreign material such as a rod-shaped metal, wire, string, net, thermosetting plastic, or a foreign material such as a thick metal plate is erroneously inserted from the waste insertion slot 4. Alternatively, after the PET bottle 10 and the foreign matter are simultaneously inserted, the door member 5 is opened and the PET bottle 1 is opened.
In a case where only 0 is taken out and foreign matter remains, the control unit 60 (crushing control unit 65) performs a control based on the detection signals from the microswitch 9, the proximity sensor 35, and the reflection type sensor 36 based on the detection signals. The drinking mouth 10c of the PET bottle 10 into which the proximity sensor 35 is inserted from the waste insertion opening 4 is not close (the drinking mouth 10c is not fitted into the narrow portion 11c of the reverse insertion regulating member 11, and the PET bottle 10 Is not inserted to the predetermined standby position), when the reflective sensor 36 detects that the object (the body 10b of the PET bottle 10) is not present, or when the micro switch 9 is When detecting that the door member 5 is in the open state, the flapper supporting solenoid 20 is not operated, and the PET bottle 10 is
Since it is not sent to 9, 40, PET bottle 1
Even if only the PET bottle 10 is taken out after the 0 and the foreign matter are inserted at the same time and the foreign matter remains, the foreign matter is not sent to the rotary blades 39 and 40, and the foreign matter is reliably prevented from being crushed. be able to.

The proximity sensor 35 and the reflection type sensor 36
Are provided at predetermined intervals in the insertion direction of the PET bottle 10, so that the length of the PET bottle 10 (object) waiting on the flapper 14 in the insertion direction can be detected. 10c and taper 10
By distinguishing the PET bottle of a shape cut from the middle part of the body 10b from the PET bottle 10 of the normal shape except for d, the PET bottle with a short length can be reliably detected as a foreign substance. As a result, when a foreign substance not to be treated is erroneously inserted into the waste disposal apparatus 1, it is possible to prevent the inserted foreign substance from being crushed.

The proximity sensor 35 and the reflection type sensor 36
Are provided at predetermined intervals in the vertical direction when viewed from the insertion direction of the PET bottle 10, so that the proximity sensor 35
And the reflective sensor 36 detect different portions in the vertical direction of the PET bottle 10 when viewed from the insertion direction of the PET bottle 10, so that the PET bottle 10 in the height direction of the PET bottle 10 being put on standby is detected. Detection becomes possible, and waste can be more reliably detected in distinction from the above-described foreign matter.

The proximity sensor 35 is a PET bottle 1
0 is the narrow portion 11c of the reverse insertion restricting member 11
Therefore, it is possible to reliably detect that the PET bottle 10 has been fitted to the reverse insertion restricting member 11 and the PET bottle 10 has been inserted to the predetermined standby position.

Further, 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 micro switch 9 and the proximity sensor 35
The N signal is not output, and the control unit 60 does not operate the flapper drive solenoid 16, the flapper support solenoid 20, the rotary blade drive motor 48, and the like.

On the other hand, when the PET bottle 10 is inserted into the reverse insertion restricting member 11 from the drinking port 10c side, the door member 5
Can be closed, an ON signal is output from the microswitch 9 when the door member 5 is closed,
The output of the ON signal from the microswitch 9 and the proximity sensor 35 and the output of the OFF signal from the reflection sensor 36 allow the control unit 60 to operate the flapper drive solenoid 16, the flapper support solenoid 20, the rotary blade drive motor 48, and the like. Become. As a result, the PET bottle 10 having a tapered tip can be reliably guided from the drinking port 10c side to the rotary blades 39, 40, and the PET on the rotary blades 39, 40 can be provided without newly providing a pushing means or the like.
The ability of the bottle 10 to bite into the drinking mouth 10c is improved.
The ET bottle 10 can be reliably crushed,
It is possible to reduce the size of the device, reduce the number of parts, and reduce the cost.

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 is 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 micro switch 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 portions F of the rotary blades 39, 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.

In the above-described embodiment, an example is shown in which the present invention is applied to the waste treatment apparatus 1 for crushing the PET bottle 10 as waste, but the present invention is not limited to this. The present invention may be applied to a waste treatment apparatus that crushes a metal empty can or a glass empty bottle as waste.

Further, in this embodiment, it is detected that the drinking mouth 10c of the PET bottle 10 is fitted into the narrow portion 11c (the PET bottle 10 is inserted to a predetermined standby position). For this reason, the proximity sensor 35 is used, but instead of using the proximity sensor 35, a configuration may be adopted in which a reflection sensor or a detection switch such as a limit switch is used. Also, the proximity sensor 35
Is configured such that the drinking spout 10c is fitted into the narrow portion 11c to detect that the drinking spout 10c is approaching, but may be configured to detect that the tapered portion 10d is approaching. And any other device that detects that the PET bottle 10 has been inserted to the predetermined standby position.

In this embodiment, the reflection type sensor 36 is used to detect whether or not an object (the body 10b of the PET bottle 10) is present in the reverse insertion restricting member 11 (presence or absence of the PET bottle 10). However, instead of using the reflective sensor 36, a proximity sensor or a detection switch such as a limit switch may be used. Also, the position where the reflection type sensor 36 is provided is not limited to the above-described embodiment, and a predetermined distance from the proximity sensor 35 (first detection unit) when viewed in the insertion direction of the PET bottle 10 (waste). Any position may be used.
