DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to embodiments shown in the drawings.

Embodiment 1 In FIG. 2 to FIG. 5, reference numeral 2 is a collection container for a drink container, and a lid body to which a substrate 1 having a drink container input port 3 is attached is attached to an upper opening of the collection container 2. 4 is worn. An oscillating cylinder 5 having an air core coil, which will be described later, is provided on the edge of the drink container inlet 3. Inside the substrate 1, a door 6 for opening and closing the drink container inlet 3 is suspended via a support shaft 7. 8 is its support shaft 7
Shows the bearing.

A solenoid 9 is fixed to the back side of the lid 4 and serves as a regulating means for the door 6. The operating rod 10 of the solenoid 9 has a tip end which is made of an elastic body such as hard rubber. The opening restriction member 11 is attached,
The other end of the operating rod 10 is connected to an operating shaft 12 of a solenoid 9, and the intermediate portion of the operating rod 10 is pivotally supported by a fulcrum 13.

Reference numeral 14 is a control circuit for controlling the solenoid 9, and the control circuit 14 has a circuit configuration shown in FIG.

That is, 15 is an oscillator, and this oscillator 15 is provided with an air-core coil 16 wound in the oscillation cylinder 5. Reference numeral 17 is a frequency dividing circuit for dividing the oscillation pulse from the oscillator 15, 18 is a first monostable multivibrator, 19 is an AND circuit, 20 is a second monostable multivibrator, 21 is a driver circuit, and 22 is a solenoid 9. The alarm indicator light provided in parallel is shown.

The above is the configuration of the sorting apparatus according to the present embodiment.
Next, its operation will be described.

As shown in FIG. 4, the drink container inlet 3 provided in the recovery container 2 is closed by a door 6 which is always suspended by a support shaft 7, but is provided on the back side of the substrate 1. Since the solenoid 9 is not energized at all times, the door opening restricting member 11 attached to the tip of the operating rod 10 is lowered and not locked with the door 6. Can be freely pushed open from the oscillation cylinder 5 side.

Therefore, when a drink container to be put into the collection container 2, that is, a paper cup is inserted into the input port 3, the door 6 is opened by the insertion force, and the paper cup is put into the collection container 2 from the input port 3. can do.

Next, when the cans are positioned in the inlet 3, the solenoid 9 is excited and the door opening restricting member 11 is locked to the lower side of the back side of the door 6, as shown in FIG. As a result, the door 6 cannot be pushed open, so that the cans cannot be put into the collection container 2.

The exciting operation of this solenoid will be described below with reference to FIGS. 6, 7 and 8.

In other words, the oscillator 15 outputs an oscillation signal by the air-core coil 16 and the capacitor forming the oscillator 15, and the oscillation signal is divided by the frequency dividing circuit 17 to obtain a pulse having a characteristic waveform T _1. To be Further, the first monostable multivibrator 18 obtains the pulse T ₁ synchronized with the air-core coil 16, and since there is no deviation between these waveforms, an output signal does not occur from the NAND circuit 19,
Therefore, the solenoid 9 is never excited, and
The state shown in is maintained.

Therefore, when the cans (metal) are positioned (inserted) in the oscillation cylinder 5, the inductance of the air-core coil 16 changes, and as shown in FIG. 8, the first monostable multivibrator is used. A deviation occurs between the characteristic waveform T ₁ and the divided pulse waveform T ₂ that does not pass through the monostable multivibrator. A discrimination signal (d ') is output from the NAND circuit 19 due to a time difference between the waveform T ₂ and the characteristic waveform T _1, and a predetermined time set by the second monostable multivibrator 20 from the time when the discrimination signal is generated. The solenoid drive signal of T ₃ is output, and as a result, the solenoid 9 is excited for the set time T ₃ , the door opening restricting member 11 rises as shown in FIG. 5, and the opening of the door 6 is blocked.

That is, the empty can (metal) is a drink container inlet 3
When positioned inside, the inductance of the air-core coil 16 changes, and the solenoid 9 is excited to operate for a fixed time based on this change signal, and the door 6 cannot be opened.
The empty can cannot be put into the collection container 2.

During the exciting operation of the solenoid 9,
Since the warning indicator light 22 is turned on, it can be visually confirmed that the door 6 is not opened by turning on the warning indicator light 22.

Further, if the door 6 is forcibly pushed open in the door opening prevention state, the solenoid 9, the operating rod 10 and the like may be damaged. Therefore, in order to prevent the damage, the door opening restricting member 11 is hard. It is made of an elastic material such as rubber. Therefore, if the door 6 is forcibly pushed open when the door is prevented from opening, the door opening restricting member 11 bends to prevent damage to the solenoid, operating rod and the like.

Further, since the door 6 is retained by a simple locking structure in which it is hooked on the bearing 8 via the support shaft 7,
The door 6 can be easily removed from the substrate 1, and the door 6 can be cleaned very easily.

Although the solenoid 9 is used as the door opening restricting means in the above embodiment, the invention is not limited to this.
It may be a motor or the like.

Embodiment 2 In Embodiment 1 described above, the sorting apparatus is configured so that only the paper cup can be put into the collection container 2. However, as shown in FIGS. 9 and 10, for example, as shown in FIGS. If the vertical direction is reversed from the vertical direction of the solenoid 9 shown in the first embodiment, when the empty can is positioned at the drink container inlet 3, when the solenoid 9 is excited, the operating shaft 12 presses the spring 23. Door opening / closing control member 1 because it rises against the force
1 is separated from the door 6, and as a result, an empty can can be charged into the recovery container 2 through the drink container charging port 3. Also, when the paper cup is positioned at the drink container insertion port 3, the solenoid 9 is not excited as in the first embodiment, and the door 6 is locked by the door opening restricting member 11 and pushed open. Therefore, the paper cup cannot be put into the collection container 2.

Therefore, in the case of the second embodiment, the recovery container 2
Only empty cans can be sorted and stored inside.

Embodiment 3 In FIG. 11, in this embodiment, the inside of the collection container 2 is divided into two, one of which is a paper cup storage section 2A and the other is a can storage section 2B. If the sorting apparatus described in the first embodiment is provided and the sorting apparatus described in the second embodiment is provided on the can housing portion 2B, one collection container 2 can store a paper cup and a can, respectively. It can be collected separately.

Embodiment 4 In FIGS. 12 to 15, this embodiment is intended to separate an aluminum can and a steel can.

That is, in this embodiment, as shown in FIG. 12, a resistor and a capacitor are provided between the NAND circuit 19 and the second monostable multivibrator 20 in addition to the circuit configuration shown in FIG. 6 described above. Integrating circuit 24 consisting of The other circuits are the same as those in FIG.

Therefore, in the fourth embodiment, similarly to the first embodiment, the oscillator 15 outputs the oscillation signal by the air-core coil 16 and the capacitor that constitute the oscillator, and the oscillation signal is output by the frequency divider circuit 17. Frequency-divided and characteristic waveform T ₁
Pulse is obtained. Further, the first monostable multivibrator 18 obtains the pulse T ₁ synchronized with the air-core coil 16, and since there is no deviation between these two waveforms, no output signal is generated from the NAND circuit 19 and therefore the solenoid 9 is excited. It is not operated and the door 6 remains closed.
Then, when the steel can is positioned (inserted) in the oscillation cylinder 5, the inductance of the air-core coil 16 changes, and FIG.
As shown by, the deviation occurs between the characteristic waveform T ₁ by the first monostable multivibrator and the divided pulse waveform T ₂ ′ that does not pass through the first monostable multivibrator, and as a result, the NAND circuit 19 The discrimination signal (d ') having the pulse width T ₃ is output, the discrimination signal (d') is processed by the integrating circuit 24, and the detection signal (f) is output. Since the level is lower than the threshold position, the solenoid does not excite and the door remains closed so that the steel can cannot be put into the recovery container 2.

Next, the aluminum can is positioned (inserted) in the oscillation cylinder 5.
Then, the inductance of the air-core coil 16 changes,
As shown in FIG. 15, a large deviation occurs between the characteristic waveform T ₁ of the first monostable multivibrator and the divided pulse waveform T ₂ "that does not pass through the first monostable multivibrator, and as a result, A discrimination signal (d ') having a pulse width T ₄ is output from the NAND circuit 19, the discrimination signal (d') is processed by the integration circuit 24, and a detection signal (f) is obtained.
However, since the level of this detection signal (f) is higher than the threshold position, the solenoid is energized and the door can be opened, and the aluminum can is thrown into the collection container 2. You can

Therefore, it is possible to surely separate the steel can and the aluminum can, and it is possible to expect the same effects as those of the first embodiment.
