BACKGROUND ART In recent years, beverages such as juice, beer, and alcoholic beverages have been changing from bottles to cans, and the demand for these cans is increasing, instead of being made of iron or tin plating, and instead of aluminum cans that are press-formed from aluminum sheets.

Most of these empty drinking water cans are thrown away in fields, mountains, roadsides, parks, etc., which is a waste of resources and also causes pollution due to empty cans being abandoned. Become.

However, the current situation is that all these empty cans are collected, and even if they were to be melted down to obtain raw materials, it would not be profitable to produce anything other than aluminum.

In the drawing, numeral 4 is a running indicator light, 5 is a stop indicator light, 26 is a brake, 27 is a brake solenoid valve,
71 is a switchboard, A is an empty iron can and an empty aluminum can, B
is compressed iron and aluminum empty cans, C is bottles, P is
is the compressive force, S is the recess, and T is the pressing force.

Regarding the operation, first, insert an empty bottle C or an empty can with a large amount of drinking water remaining into the sorting box 11 through the insertion hole 9,
Thereafter, when the insertion door 2 is closed, the drive motor 24 is activated and the main crank 31 is rotated. As the main crank 31 rotates, the piston rod 32 moves forward, and at the same time, the empty can sorting box drive rod guide roller 42 starts moving forward.

As the guide roller 42 moves forward, it is integrated with the empty can sorting box drive rod 13.

The third drive lever 16 of the first drive lever 14 is moved to the right in the drawing via the spring 18.

The sorting box 11 whose upper wall is fixed to the third drive lever 16 is guided by the guide shaft 12 and moves, and when it comes to the bottom opening door 23 for bottles, a large amount of bottles C or drinking water remains. Since the empty can exceeds the standard weight, the tip of the bottom opening door 23 is
5, and at the same time as the bottom opening door 23 opens, the bottles C are discharged from the main body casing 1 through the chute 22 through the discharge port 7.

After the bottles C are discharged to the outside from the chute 22, the first drive lever 14 is stopped by a stopper, and the first drive lever 14 is rotated to the right in the figure by the elasticity of the reversing spring 19. As the first drive lever 14 rotates, the sorting box 11 moves backward, and when it reaches near the bottom-opening door 23, it moves forward while pressing the reversing lever 70 that has fallen to the right, and returns to the starting position using the return stopper. and a rod 69 pivotally connected to the reversing lever 70.
is pulled, the bottom-opening door 23 pushes up the roller 65 from below, rises, and is locked by the roller 65. (See Fig. 5) Next, when the empty aluminum can A is inserted into the sorting box 11 through the insertion hole 9 and the insertion door 2 is closed, the sorting box 11, like the empty bottle C, is moved to the guide shaft 1.
2 and start moving.

However, unlike bottles, the empty aluminum can A is lighter than the standard weight, so it passes over the bottom-opening door 23, and as soon as it reaches a predetermined position, it passes through the opening and is thrown into the chute 2.
It will fall to 1.

The empty aluminum can A that has passed through the chute 21 slides into a V-shaped lower guide 39 inside the compressor.

The empty aluminum can A in the lower guide 39 is raised by the hammer cam 33, which rotates at the same time as the piston head 38 advances, and the hammer head 36 suddenly drops and hits the side surface of the empty aluminum can A.
As shown in Figure A, a recess S is formed by the pressing force,
Subsequently, the moving piston head 38 and the compressive force P are clamped and compressed by the fixed head 37, and the aluminum can A is transformed into a compressed can _B1 as shown in FIG. 11C.
When the compression can B ₁ falls onto the movable chute 45 with an abbreviated shape on its side, the empty aluminum can A slides down regardless of the presence or absence of the magnet 46 because it is a non-magnetic material, and the distribution chute 52 provided at the bottom is tilted. It falls into the aluminum compression can container 72 through the surface and is housed therein.

However, when the compressed empty can is made of iron, it is attracted to the magnetic movable chute 45, preventing the empty can from falling by itself, and then the movable chute swings into the L-shaped cam by the piston rod 32 and main crank 31, which move backward. By pressing and rotating one end of 48, the swing rod 47 pivotally connected to the L-shaped cam 48 is pulled by the magnet 46 together with the movable chute 45, and when the required angle is reached, the swing rod 47 is separated from the movable chute 45.

Since the movable chute 45 loses its magnetism, the compression cans of the movable chute 45 fall into the iron compression can container 73.

Next, as shown in FIG. 10, when the empty can (regardless of whether it is an aluminum can or an iron can) is compressed, the empty can presses the coin ejection limit switch 61 provided on the fixed head 61. Solenoid valve 62
is actuated, the rod of the solenoid valve 62 is attracted, and at the same time the movable chute 63 is pulled, and the coins on the movable chute 63 are dropped into the coin chute 64.

After compressing the empty can, the piston head 38
When the coin case lever 60 moves backward, the flange of the coin case rotating rod 56 is pushed forward, and the bolt of the coin case rotating lever 57, which is pivotally connected to the rotating rod 56, connects to the operating plate, which has an approximately L-shaped cross section. Lock and press the coin case 54.
rotates 1/3 of a turn, and the spring 58 stops the rotation.

As described above, customers insert empty cans into the device of the present invention installed at stores, station kiosks, etc. without considering the material of the empty can or the empty bottle, so it is automatically determined whether the can is an empty can or a bottle. , the bottle will fall into the chute and the coin will not be returned.

However, in the case of aluminum cans and iron cans, after they fall into the chute, they slide into the V-shaped lower guide inside the compressor, and a recess is first formed in the side surface of the empty can with a hammer, and then , it is compressed and crushed by the piston head and reduced to a fraction of its volume.

When the compressed and crushed empty cans fall below the gap, they are automatically sorted into steel or aluminum by a movable chute and discharged into their respective containers.

Therefore, among the empty cans, what is recycled (waste)
A distinction is made between those that are and those that are not.

Therefore, various empty cans mixed in as in the past,
It saves you the trouble of sorting from bins.

For empty cans other than bottles, the coins are promptly returned to the customer at the stage of compression, regardless of the material, so customers will never throw away empty cans, and this will reduce the pollution of empty cans. At the same time, it leads to the recycling of aluminum cans, and the economic effect is immeasurable in terms of resource identification.

Although the compression of empty cans is illustrated and explained using a crank mechanism, the compression of empty cans according to the present invention is not limited to the crank mechanism, but can be performed by other means, such as a screw mechanism or a cylinder (empty or hydraulic) mechanism, with the same operation and effect. play.
