For this reason, in each local government, the problem of empty can disposal has become a major problem year by year.

Conventionally, as a method for treating such empty cans, a method of placing an empty box or the like beside a vending machine, charging the used empty cans into this, and then treating this as industrial waste, which occurred in the home There was a method to dispose of it in a waste cleaning plant together with kitchen garbage.

Problems to be Solved by the Invention In these methods, the empty cans after use are put into the empty box in a hollow shape, so that the empty box is quickly filled, and the surroundings are immediately Had the disadvantage of becoming dirty.

Furthermore, metal cans are mainly made of reusable iron or aluminum, and disposal of these empty cans directly into the ground is a great economic loss for Japan, which lacks these natural resources.

Some waste treatment plants, etc., treat waste cans for reuse after use.However, steel cans and aluminum cans are mixed with other garbage. It is necessary to separate the cans from other garbage and then separate the steel cans and aluminum cans from the separated cans, which are extremely expensive. The benefits were halved.

Means for Solving the Problems In order to solve these problems, the present invention provides a simple and compact empty can separation and crushing / stacking device beside a vending machine.

And a converter 64 in communication with.

When the gate 30 is closed, the motor 62 operates. Next, the sensors 60 and 61 are activated.

When the charged can 50 is an aluminum can, the magnetic sensors 60 and 61 do not function even when energized, and the converter 64 rotates the shaft 63 in one direction (for example, clockwise in FIG. 2) after a predetermined time. To transmit the rotational force of the motor 62. Therefore, the shaft
Six impellers 66 attached to 63 are approximately 60 clockwise.
Rotate by degrees. A rake piece 67 as shown can be attached to the outer end of each impeller 66. The impeller 66
Has a length sufficient to push or scoop out the can on the can pan 40 from the can pan 40, so that the can 50 is pushed out to the left of the can pan 40 by the impeller 66, and the empty can Fall to 14.

On the other hand, when the charged can 50 is an iron can, the magnetic sensors 60 and 61 are activated, so that the converter 64 is activated and the shaft 63 is activated.
The rotation of the motor can be transmitted to rotate in the opposite direction (for example, counterclockwise in FIG. 2) to the above case. Therefore, the can 50 is pushed rightward in FIG. 2 from the can tray 40 and falls directly into the empty can crushing section 14.

Between the empty can identification section 12 and the empty can crushing section 14, a dividing plate 68 and both end plates 69, 69 as shown in FIG.
And a guide guard 70 as shown in FIG. 1 for guiding the identified can 50 to a predetermined position. The separating plate 68 is for separating cans distributed by the impeller 66 so as not to mix with each other.

The cans 50, which have been sorted to the left and right by the impeller 66 from the tray 40, respectively, slide down between the end plates 69 and the sorting plate 68 along the guard 70, and are introduced into the empty can crushing section 14.

The empty can crushing unit 14 includes a driving motor 72, a driving drum 74 driven by the motor 72, a guide roller 76, and a V-belt or chain connecting the drum 74 and the roller 76.
And 78.

The drive motor 72 is adjusted to rotate in conjunction with the activation of the motor 62. As shown in FIG. 2, the drive drum 74 has a plurality of grooves 80 formed at regular intervals. On the other hand, the guide roller 76 has a can that falls from the guide guard 70
50 to the nip 82 between the roller 76 and the drive drum 74.
A plurality of guide blades 84 are forcibly pulled into the guide blade. These guide blades 84 pass through the grooves 80 of the drive drum 74, and the can 50 is crushed at the nip 82. At this time, it is preferable that the tip of the guide blade 84 is slightly bent in the traveling direction so that the can can be embraced so that the can is forcibly supplied to the nip portion 82. The drive drum 74 is adjusted by the V-belt 78 or the like via a pulley, for example, so as to rotate at a higher speed than the guard roller 76. This facilitates the suction of the can 50 into the nip 82.

The can crushed at the nip 82 is then
It falls from 14 to the crushable empty can storage part 16 below it.

The storage section 16 is formed of left and right separate spaces 86 and 88, and the spaces 87 and 89 formed of a wire mesh or the like having an open upper surface and a lower surface through which liquid can pass are stored. ing. In these boxes, the same type of crushed cans that are sorted by the impeller 66 and crushed almost flat at the crushing portion 14 are stored from above. Vacancies 86, 88
The box housed inside is guided by rails and rollers,
It can be easily put in and out. In addition, the empty space 86,
On the lower surface of 88, a drain and a cock 90 for discharging the liquid discharged from the inside of the can can be provided.

Further, in the present case, in response to the rotation direction of the impeller 66, a cash dispenser 92 known per se may be operated so that some money is paid out for each can.

Also, the metal sensor can be mounted inside the gate 30. In this case, the empty can inlet below gate 30
A flap 31 is fixed to the lower end of the gate with a hinge 29 or the like so that the portion corresponding to 28 can be freely pushed inward and opened as shown in FIG. On the other hand, the metal sensors 39 are arranged laterally on the left and right sides of the empty can inlet 28 in the housing 18.
The main switch is arranged at a position where the main switch is activated when the flap 31 is pushed over a predetermined angle. The metal sensor 39 starts operating by the operation of the main switch. Thus, when the empty can is not metal, the flap 31 does not open any more. However, in the case of a metal can, the flap swings further upward to allow the can to be received in the measuring section 24.
If the weight is excessive, the magnets 52 and 54 are actuated to each other, and in response to this, the motor 32 is rotated and the gate 30 is lifted to discharge the can.

Effect of the Invention According to the present invention, empty cans are crushed flat at the nip portion, and thus have an empty can storage capacity of about 5 to 10 times that of the conventional storage with a cylindrical shape.

In the present invention, since only reusable metal cans can be processed, there is no need for a processing company to separate only reusable metal cans from other glass, paper, or the like.

In the present invention, since the steel can and the aluminum can are separately accumulated in advance, the work of sorting such cans is unnecessary, and reuse is easy.

Since the crushing of the empty can is forcibly performed at the nip portion between the driving drum and the guide roller with the guide blade rotating at a lower speed, the crushing process can be performed quickly and reliably.

The can collection container is guided by rollers and rails to facilitate removal of the crushed and accumulated cans.

Money can be supplied to the input person by inputting a metal can, which is expected to be used by children and greatly improves the disposal of empty cans on the road as before. .
