BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an empty can collecting machine.

[0002]

2. Description of the Related Art The structure in the vicinity of a pressing device in a conventional empty can collecting machine is shown in FIGS.
It will be described based on 1.

In the figure, reference numeral 100 is a fixed plate, which is fixedly attached to the main body of the recovery machine. Reference numeral 102 denotes a movable plate, which is the fixed plate 100.
It is arranged to face each other. Movable plate 102
Performs an advancing / retreating operation with respect to the fixed plate 100, and a press space 101 is formed between these plates 100 and 102.

Reference numeral 106 denotes an empty can receiving plate for temporarily holding the inserted empty can C in the press space 101. The empty can receiving plate 106 is arranged so that the empty can receiving portion 106 a is located immediately below the press space 101. The empty can receiving plate 106 also plays the role of a weight sensor, and when a can having a certain weight or more is thrown in, such as a can having stones filled therein or contents remaining therein. In this case, the empty can C is rotated around the mounting portion 104 so that the empty can C is dropped without being held in the press space 101.

Reference numeral 108 denotes a chute plate which bulges toward the empty can passage 110 side slightly below the central portion, and the screw 10 is attached to the fixing plate 100 above the chute plate 108.
9 has been stopped. An inclined surface 112 is formed on the chute plate 108 on the side of the empty can passage 110.

Now, the empty can C loaded into the empty can collecting machine having the above structure is once received on the empty can receiving plate 106 in the press space 101. afterwards,
The movable plate 102 advances toward the fixed plate 100 side to press the empty can C on the empty can receiving plate 106, but normally, as shown in FIGS. 7 and 8, the empty can C is completely pressed. It will be pressed in the space 101.

[0007] The empty can C is a movable plate 102.
As a result of the retreat, the paper will fall from the press space 101 toward the chute plate 108 through between the empty can receiving plate 106 and the fixed plate 100.

However, even though the empty can C has leftovers left therein and foreign substances are mixed therein, the amount of the empty can C is required to completely rotate the empty can receiving plate 106. If the amount does not reach the limit, as shown in FIG. 9, the empty can C may be received while the empty can receiving plate 106 is slightly lowered.

If empty can C is pressed in this state, empty can C
As a matter of course, as shown in FIG. 10, the one of the two becomes a half-crushed state. It is safe to say that the empty can C is in a half-crushed state, but then the following problem occurs. That is, as shown in FIG. 11, even after the movable plate 102 is retracted from the fixed plate 100 after pressing, in the empty can C which is in a semi-crushed state, the empty can C is replaced by the empty can receiving plate 106. There was a problem that the empty can C was clogged in the vicinity of the lower part of the press space 101 because it was caught between the chute plate 108 and the chute plate 108.

[0010]

Therefore, in order to solve the above-mentioned problems, the following means have been taken. That is, in the empty can collecting machine of the present invention, a press space is formed between the fixed plate and the movable plate that moves forward and backward with respect to the fixed plate, and the empty can receiving portion is near the lower part of the press space. Is provided, the empty can receiving plate is provided by the empty can receiving plate to receive the empty can introduced into the press space in the space, and the empty can in the press space is fixed to the fixing plate. While pressing by a movable plate that advances to the plate side, after pressing, the movable plate retracts from the fixed plate to drop an already pressed can from the press space, the empty can collecting machine, As the movable plate retracts, the empty can receiving plate is rotated so that the empty can receiving part of the empty can receiving plate retracts from the press space. It is an.

[0011]

In the empty can collecting machine of the present invention, the empty can receiving plate rotates as the movable plate retreats, and the receiving portion of the empty can receiving plate retracts from the press space. Even if the above condition occurs, there is no concern that the empty can will be caught between the empty can receiving portion of the empty can receiving plate and the chute plate.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings, but the present invention is not limited thereto.

FIG. 1 shows the internal structure of the recovery machine body 12 in the empty can recovery machine 11. In the figure, reference numeral 17 is a canning sorting device. This canning / sorting device 17 is provided with a sorting sensor for determining whether or not a can that has been loaded through a loading port (not shown) provided in the front door 15 is an empty can to be pressed.

Reference numeral 18 is a pressing device, which is a device for crushing the empty cans C judged by the can selecting device 17 to be pressed.

The pressed empty canister C is the pressing device 1 described above.
A distribution device 19 arranged below the device 8 determines whether the container is an iron can or an aluminum can, and a distribution plate 20 through which the empty can C passes when it falls.
The cans C are lowered to the left or to the right, and the sorted empty cans C are respectively stored in predetermined positions of the collection box 21.

FIG. 3 is a side view schematically showing the vicinity of the pressing device in the empty can collecting machine. As shown in the figure, a fixing plate 30 is fixed to the recovery machine body 12 either directly or indirectly.

Reference numeral 32 denotes a movable plate, which is arranged so as to face the fixed plate 30 and moves forward and backward with respect to the fixed plate 30. A press space 33 is formed between the fixed plate 30 and the movable plate 32.

The principle of movement of the movable plate 32 is shown in FIG.
A description will be given based on (a) and FIG. 2 (b). As shown in the figure, an eccentric cam 2 fixed at a central position is provided on a rotary shaft 4 of a press motor 3. A support shaft 5 is fixed at a position off the center of the eccentric cam 2. The support shaft 5 is connected to the driving member 7 through a bearing 6, and the driving member 7
Is fixed to the movable plate 32. Then, empty can C
When is input, the press motor 3 is driven, the eccentric cam 2 is rotated accordingly, and the movable plate 32 moves to the fixed plate 30 side.

Reference numeral 44 is a V-shaped chute plate disposed below the press space 33 and the fixed plate 30. .. A sliding inclined surface 48 is formed on the chute plate 44 on the side of the empty can passage 46. The empty can C pressed by the pressing device 18 or the empty can C dropped as it is due to overweight is the chute plate 4 described above.
4 is guided by the recovery box 21 by sliding on the sliding inclined surface 48.

The chute plate 44, as shown in the figure,
A screw 50 is fixed to the fixed plate 30 at the upper end portion 44a.

Reference numeral 56 denotes an empty can receiving plate, which is used to receive the supplied empty can C by an empty can receiving portion 56a of the empty can receiving plate 56 and temporarily hold it in the press space 33 ( (See FIG. 3). The empty can receiving plate 56 also functions as a weight sensor, and when a can having a certain weight or more is thrown in, such as a can having stones filled therein or contents remaining therein. The weight of the empty can receiving plate 56 depends on its weight.
Has a mechanism in which the can C is largely rotated about the mounting portion 58 to drop the can C without pressing. The empty can receiving plate 56 is attached to the mounting portion 58.
Even if it is pivoted about, the original state can be restored according to the urging force of a spring (not shown).

Further, in the empty can receiving plate 56, about 45 to 90 degrees around the mounting part 58 so that the empty can receiving part 56a retracts from the press space 33 as the movable plate 32 begins to retract. It is configured to rotate.

The means for rotating the empty can receiving plate 56 is not particularly limited, and a conventionally known method can be used. For example, as shown in the figure, the motor M is arranged in the vicinity of the empty can receiving plate 56, and the movable plate 3
When the motor 2 drives the motor M, the motor M is controlled to drive at the same time when the motor 2 starts to retreat, and the motor M drives the empty can receiving plate 56 to rotate around the mounting portion 58. One of them is. Alternatively, a method of rotating using a solenoid or a spring may be adopted. In short, when the movable plate 32 starts to retreat, the empty can receiving plate 56 starts to rotate at the same time, and when the movable plate has completely retracted, the empty can receiving plate 56 is also completely retracted from the press space 33. Any method that can be controlled may be used.

However, since the empty can receiving plate 56 has to receive the empty can to be loaded next, it is necessary to return it to the original position. The means for returning to such an original position is not particularly limited, and the method by the reverse rotation of the motor M described above, the method of releasing the forward rotation mechanism of the motor M and relying on the biasing force of the spring, and the like. Can be mentioned.

Now, the empty can C is loaded from the loading port of the front door 15 and should be pressed by the can sorting device 17.
When it is determined that the empty can C is received by the empty can receiving plate 56 in the pressing device 18, the empty can C is arranged in the press space 33. At this time, even though the empty can C has leftovers left therein and foreign substances are mixed therein, the amount thereof is not enough to completely rotate the empty can receiving plate 56. If the amount is enough, as shown in FIG. 3, the empty can receiving plate 56 may stay with a slight rotation.

When the movable plate 32 advances toward the fixed plate 30 in the above state, the empty canister C is in a half-crushed state, as shown in FIG.

After the empty can C is pressed, the movable plate 32 begins to retreat. At this time, a drive command is input to the motor.
As a result, the empty can receiving plate 56 is moved to the empty can receiving portion 56.
The a rotates so as to retract from the press space 33. That is, as shown in FIG. 5, the empty can receiving plate 56 starts to rotate as the movable plate 32 moves backward, and when the movable plate 32 has completely returned to its original position,
As shown in FIG. 6, the empty can receiving portion 56a is completely retracted. As a result, even if the empty can C after pressing is in a semi-crushed state, the chute plate 44 will not drop when the empty can C falls.
It does not become sandwiched between the empty can receiving portion 56a.
