Abstract

PURPOSE:To provide a crushing machine for empty cans which is simplified in construction and can press surely cans by each piece, by mounting a tread rod in the lower part in a machine box in such a way that the front end thereof is made turnable by a shaft in a lateral direction and projecting the rod backward through the longitudinal hole opened in the lower part on the rear side of the machine box. CONSTITUTION:The operator places empty cans 17 on a guide plate 19, holds a handle part 23 with the hand, and treadles down a tread rod 2 once with the foot placed on the foot plate thereof. As a result, the foremost can 17 on the plate 19 is rolled down into the press part between a pressing plate 6 and a pressure receiving plate 16. The operator treadles down the rod 2 again to press the can 17 already dropped into the press part by means of the plate 6 and the plate 16; then the flattened can 17 pushes a lid 23 to open upon returning of the rod 2 and is automatically discharged through an outlet 22 to the outside of a machine box 1. The 2nd can 17 on the plate 19 is dropped into the press part before or after said discharging so as to be ready for the next pressing. Thereafter, the cans 17 are pressed and discharged to the outside of the box 1 at every treadling of the rod 2, while the cans 17 are fed by each piece into the press part and the cans 17 are pressed successively.

Description

[Detailed Description of the Invention] There are various empty can crushers, but most of them have complicated structures.

The present invention has a simplified structure, and yet allows only one can to be used.
Cans can be pressed flat by feeding them one by one.5
The present invention will be described below with reference to an embodiment of the empty can crusher.

In the figure, 1 is a machine box, at least the top of which is open. The front end of a foot lever 2 is rotatably attached to the lower part of the machine box on a shaft 3 in the left-right direction. The foot plate 5 is provided with a foot plate 5 at the rear end.

Further, the lower part of a pressing rod 7 having a suppressing plate 6 on the front surface is rotatably attached to the foot rod shaft 3. The lower end of the link lever 8 is attached to the upper side of the pressing rod 7, and the lower end of the link lever 8 is attached to the left-right axis 9
1C, and the upper end of this link lever 8 is connected to the upper end of another link lever 11 whose lower end is rotatably attached to the left-right shaft 10 in the machine box. It is connected at. However, the lever shaft 12 has a lower end attached to the side of the foot lever 2 with a bin 13 in the left and right direction.
The upper end of an actuating rod 14 rotatably mounted at is rotatably connected, and a tension coil spring 15 is stretched between the pressing rod 7 and the foot rod 2.

Therefore, when the foot lever 2 is stepped down with the foot placed on the seven-piece plate 5 at the rear end, the link levers 8 and 11 are expanded by the operating rod 14, and the pressing rod 7 is tilted forward as shown by the phantom line. Then, with the pressure receiving plate 16 provided on the back side of the front plate of the machine box 1, the can 17 that has fallen between the two is pressed into a piece, and after this pressing, the force pressing on the foot lever 2 is released. The restoring force of the coil spring 15 causes the foot lever 2, the pressing rod 7, and each link lever 8, 11 to return to its original state.

The above is an explanation of the press mechanism, but in the present invention, the press mechanism is further designed so that cans can be accurately fed one by one between the suppression plate 6 and the pressure receiving plate 16.

In other words, at the top of the opening of the machine case, the rear edge is aligned with the left and right axis 1.
A rotatable guide plate 19 is provided at 8, and a vertical foot plate 2 protrudes from the lower surface of this guide plate.
0 is the connecting shaft 1 between the link levers 8 and 11.
It is supported by 2.

Also, from the back side of the upper part of the front panel of the machine case, a stopper 2 is provided with the rear end 21a facing above the front end of the guide plate 19.
1 is provided protrudingly, and the gap a between the rear end 21a of the stopper 21 and the upper surface of the front end of the guide plate 19 is such that when the foot lever 2 is returned to its position and the guide plate 19 is in the state shown by the solid line, K is smaller than the diameter of the empty can 17, but in the state shown in the phantom line where the link lever 8.110 connecting shaft 12 is lowered by pressing down on the foot lever 2, and the guide plate 19 is tilted downward, the can is stored on the guide plate 19, but the foot lever 2
When the button is pressed once, only the first can 17 rolls down into the press section between the press plate 6 and the pressure receiving plate 16. Next, when the foot lever 2 is pressed down again with the foot, the can 17 that has already fallen into the press section is flattened by the pressing plate 6 and the pressure receiving plate 16, and the force of pressing the foot lever is released, thereby releasing the guide plate. When the machine returns, the next can rolls down to the press section between the suppression plate and the pressure receiving plate and waits for the next press, and the previously pressed can is placed in a hole at the bottom of the front panel of the machine box. The hinge lid 23 of the outlet 22 is pushed open to allow the product to be discharged out of the machine box, and reference numeral 23a indicates a hinge bin of the lid.

In the drawing, reference numeral 24 indicates a transparent side plate that allows the inside to be seen to some extent, and 25 indicates a handhold portion.

The can crusher of the present invention has the structure described above and is used in the following manner.

Place the empty can 17 on the guide plate 19, and hold the handhold part 25.
Hold it down with your hand and step down once on the foot lever 2 with your foot hooked onto the foot plate 5. As a result, the first can 17 on the guide plate 19 rolls down into the press section between the press plate 6 and the pressure receiving plate 16, as described above.

Then, when the foot lever 2 is depressed again, the can 17 that has already fallen into the press section is pressed by the pressing plate 6 and the pressure receiving plate 16. This pressed flat can is
When the foot lever returns, push open the lid 23 and open the exit 2.
Around this time, the second can on the guide plate (19) rolls down to the press section and waits for the next press. Therefore, from now on, each time the foot lever is stepped on, a can is pressed and ejected from the machine box, but on the other hand, cans are fed one by one into the press section, and cans can be pressed one after another.
