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 In recent years, an empty can collecting machine for collecting empty cans made of iron or aluminum used as containers for various beverages has been used from the viewpoint of resource saving. In this empty can collecting machine, an empty can is loaded into a loading port provided on a front door. The empty can passes through the input port and is detected by a detection sensor that is provided in the empty can collection machine and detects the inserted empty can. Based on this detection output, the pressing device inside the empty can collecting machine is activated to press the inserted empty can. The pressed empty can is once received by the receiving member, and is driven so as to incline the receiving member so that the empty can is dropped and accumulated in the recovery box below the pressing device.

On the other hand, there are two types of empty cans, one made of iron and the other made of aluminum, and the processing method when reusing them as resources is different, and it is necessary to separate them. Therefore, the sorting device including the receiving member discriminates whether the inserted empty can is made of iron or aluminum by using, for example, magnetic detection means. Further, the recovery box is also divided into an iron can and an aluminum can, and the sorting device changes the inclination direction of the receiving member based on the detection result of the detection means, and the material of the can. It is designed to be dropped into the collection box corresponding to.

Further, as shown in FIG. 7, a pair of pulleys rotatably driven by a motor 2 rotatable in both forward and reverse directions is mounted on a receiving member 1 for receiving an empty can 10 after pressing. A drive mechanism 5 constituted by 3 and a belt 4 is provided, and a scraping device 7 having an arm 6 which is connected to one of the pulleys 3 and is rotationally driven is provided. By moving the arm 6 in both directions, the empty can 10 is blown off, and the collecting box 8 below the device 7 is removed.
There is also a technology in which any of the above 9 is made to fall and be accumulated. .

[0005]

In the above-mentioned first conventional empty can collecting machine, the pressed empty can is dropped into the collecting box corresponding to the material of the empty can. Since they fall to almost the same position, they are not accumulated uniformly inside the collection box, but locally accumulated high. Therefore, even if the full-can sensor that is provided near the top of the collection box and detects that the empty cans are full after pressing the collection box, even if the full-can state is detected There is a problem that there is a lot of space left and it cannot be efficiently stored in the collection box. Such a problem is the same in the second conventional example shown in FIG.

An object of the present invention is to solve the above-mentioned technical problem and to provide an empty can collecting machine which can efficiently perform the operation when accumulating the empty cans that have been thrown therein. ..

The sensor 37 and the iron can sensor 38 are connected.

FIG. 5 shows a first example of the empty can collecting machine 11 of this embodiment.
3 is a flowchart showing an example of the operation of FIG.

In the present embodiment, it is assumed that the material of the empty can 16 to be put in is significantly more aluminum than iron. In step a1, the empty can input sensor 26
The insertion of the empty can 16 is detected. At step a2, it is determined whether the empty can 16 is a can as a beverage container.
If it is a can, the sorting sensor 39 detects it, and if it is an empty can 16 as a beverage container, it is pressed by the pressing device 18 and dropped to the dropping position 42 shown in FIG. 1 on the receiving plate 20 of the sorting device 19. Then, it is mounted on the receiving plate 20. Step a3
Then, the material of the empty can 16 on the receiving plate 20 is detected, and it is determined in step a4 whether the material of the empty can 16 is iron or aluminum.

When it is detected that the material is aluminum, for example, in step a4, the process proceeds to step a5, and the rotation direction flag D of the motor 27 is moved to the belt 30 in the direction of arrow A1 in FIG. Set the driving value to "1". A flag T1 indicating the driving period of the motor 27, that is, the traveling distance of the belt 30 is set to a value obtained by reversing the current value, and the empty can 16 is moved from the dropping position 42 to the first stopping position 43 in FIG. The value is set to "1".

At step a6, the motor 27 is driven in the direction of arrow A1 based on the value of the flag D. In step a7, it is determined whether or not the moving piece sensor 32 has detected the passage of the moving piece 31 by the number of times n corresponding to the value of the flag T1. That is, the empty can 16 is moved to the falling position 4 in FIG.
Flag T when moving from 2 to the first stop position 43
When the value "1" is 1, the number of detections is n = 1, and when the value of the flag T1 is "0" when the empty can 16 is moved from the drop position 42 to the second stop position 44 in FIG. Is. That is, in steps a4 to a6, the motor 27 is driven until the determination in step a6 becomes affirmative. When the moving piece sensor 32 detects that the moving piece 31 has passed once, the determination at step a7 becomes affirmative, and at step a8, the motor 27 is detected.
Is stopped, and the plunger 35 operates in step a9,
The receiving plate 20 is angularly displaced around the support shaft 33 in the arrow B1 direction, and the empty can 16 moves from the first stop position 43 in FIG.
It is dropped in the collection box 21 below 9.

Next, an empty can 16 is loaded, and step a5
When it is determined that the belt 30 is made of aluminum again, the traveling direction flag D of the belt 30 has the same value "1" as the previous time, but the traveling distance flag T1 of the belt 30 is the value "0" obtained by reversing the previous value. , And the empty can 16 moves to the second stop position 4 in FIG.
It is moved to 4 and is dropped in the lower recovery box 21 at this position. When the driving of the plunger 35 is stopped, the rod 35a and the receiving plate 20 are pulled by the spring force of the tension spring 34, and the receiving plate 20 is angularly displaced in the direction of arrow B2 in FIG. 1 to return to the initial state. To do.

On the other hand, if the determination in step a4 is negative and the material of the empty can 16 is determined to be iron, the process proceeds to step a10, the flag D is set to "0", and the belt 30 of FIG. Run in the direction of arrow A2. The flag T1 related to the distance is set to "1". Therefore, in steps a6 and a7, the belt 30 travels along the direction of the arrow A2 for a distance equal to the distance between the drop position 42 and the first stop position 43 and stops. Then, in step a9, the receiving plate 20 is inclined downward, and the empty can 16 drops into the iron recovery box 22.

As described above, in the present embodiment, the recycle box 2 corresponding to the material of the empty can 16 is used by using the forward / reverse rotatable motor 27, the belt 30 and the moving piece 31.
In addition to collecting into the large collection boxes 1, 2 and 22, the empty cans 16 are evenly distributed in the large collection box by changing the position of dropping the empty can 16 into the collection box each time it falls. It can be accumulated in various distributions and can be efficiently collected.

FIG. 6 is a flow chart showing another operation example of the present invention. In the present embodiment, it is assumed that the material of the empty can 16 to be charged is either aluminum or iron, or if the material is not sorted. In step b1, the empty can 1 sensor 26
An input of 6 is detected. In step b2, the sorting sensor 39 detects whether the input empty can 16 is a can as a beverage container or a spray can, and when it is the empty can 16 as a beverage container, the pressing device 18 presses it. The falling position 4 shown in FIG. 1 on the receiving plate 20 of the sorting device 19
2 and is mounted on the receiving plate 20. In step b3,
The full can sensor 40 for the collection box 21 determines whether or not the collection box 21 detects a state in which the collection box 21 is filled with empty cans 16.

If the determination in step b3 is negative, empty cans 16 can be stored in the recovery box 21, the process proceeds to step b4, and the rotation direction flag D of the motor 27 is switched to the monitor mode.
1 in the forward rotation direction of the belt 27, that is, the belt 30 is indicated by an arrow A in FIG.
It is determined whether or not the value is “1” for traveling in one direction. If this judgment is affirmative, the motor 27 is driven in the direction of arrow A1 based on the value of the flag D in step b5. In step b6, the moving piece sensor 32 moves the moving piece 31.
It is determined whether or not the passage is detected once. That is, in steps b4 to b6, the motor 27 is driven until the determination in step b6 becomes affirmative.

When the moving piece sensor 32 detects one passage of the moving piece 31, the determination in step b6 becomes affirmative, the motor 27 is stopped in step b7, the plunger 35 operates in step b8, and the receiving plate is received. 20 is angularly displaced around the support shaft 33 in the arrow B1 direction, and the empty can 16 is dropped from the first stop position 43 in FIG. 1 into the collection box 21 below the sorting device 19.

Next, when the empty can 16 is loaded, if the determination in step b3 is negative and it is determined that the full can sensor 40 has detected the full can state of the collection box 21, the process proceeds to step b9. Then, the flag D is inverted and set to a value "0" corresponding to the reverse rotation state of the motor 27, for example, and the determination at step b4 becomes negative and step b10
The belt 30 is run in the direction of arrow A2 in FIG. After that, the above-mentioned processing is repeated from step b6.

As described above, in this embodiment, the empty cans 16 that have been charged are first accumulated in the recovery box 21 by using the motor 27, the belt 30 and the moving piece 31 which can rotate in the normal and reverse directions.
When the collection box 21 is full, the other collection box 22 automatically
I switched to. As a result, the pair of collection boxes 2
1, 22 can be used efficiently.
