However, the conventional apparatus for compressing empty cans has the following problems to be solved. In the device disclosed in Japanese Utility Model Laid-Open No. 57-116601, in order to advance and retreat the pressing plate, an output shaft provided with a male screw is rotated through a driving device provided on the driving side of the cylindrical container body. Since the female screw to be screwed to the male screw of the output shaft is formed at the center of the pressing plate, the output shaft extends to the end on the opposite side to the drive side of the cylindrical container body. Due to the output shaft arranged in the center, the empty can to be put in cannot contact the center of the pressing plate,
As a result, the compression by the pressing plate was not uniform, and the compression was insufficient. Also, since the compressed empty cans are discharged to the outside by opening and closing the lid connected by a hinge structure, the discharging operation is troublesome, and when discharging a large number of compressed empty cans, the empty cans may be discharged in some cases. In some cases, the container was caught between the inner surface of the container main body and the output shaft, and could not be discharged. The one described in Japanese Utility Model Laid-Open Publication No. 1-80294 requires a very large force to crush the empty can from its longitudinal direction, and cannot be crushed by human power. A driving device such as a cylinder was required.

The present invention has been made in view of such circumstances, and provides an apparatus for crushing empty cans which can easily compress empty cans manually, has a simple structure, and can be easily discharged. With the goal.

Therefore, when the worker puts his or her weight on the step portion 34 of the foot pedal 31 in a state where the empty can 12 is not supplied to the fixing plate 21, the operator overcomes the urging force of the spring 40 and steps. By pivoting the pedal 31 around the pin 32 and pulling the connecting rods 28 and 29 connected to the upper part of the foot pedal 31 downward, the connecting rod 28 and
The compression movable plate 22 having an inclination angle larger than that of the fixed plate 21 connected to 29 is pushed down around the pin 25, whereby the distance between the fixed plate 21 and the compression movable plate 22 can be reduced. Thereafter, when the foot is released from the foot pedal 31, the compression movable plate 22 is pushed upward about the rotation base end by the urging force of the spring 40, and automatically returns to the compression start position, as shown in FIG. .

Next, the relationship between the depressing force F applied to the foot pedal 31 and the compression force C will be described with reference to FIG.
To simplify the description, the dimensions of the foot pedal 31 are
a: b = 1: 1, the depressing force F applied to the foot pedal 31 is in the direction shown by the arrow in FIG. 1, and the position where the depressing force F is applied is the front part of the depressing portion 34 shown in FIG. The dimension of the movable compression plate 22 is d: f = 1: 1, the direction of the compression force C is perpendicular to the movable compression plate 22 as shown in FIG. And α. Accordingly, when the stepping force F is applied to the foot pedal 31, a total force 2F acts on the connecting rods 28 and 29, and the compression force C at the compression position A = (2F × sinα). Therefore, when the angle α is around 90 °, the compression force C
= 2F, and 2 of the depressing force F applied to the foot pedal 31
Since the size of the empty can 12 is doubled, the empty can 12 can be effectively crushed by the doubled force 2F.

In the compression means 13 of this embodiment,
The fixed plate 21 and the movable compression plate 22 cooperate with each other by the opposing inner surfaces to guide the supplied empty can 12 to the compression position A, and compress the empty can 12 at the compression position A to form the crushed empty can 14. Thereafter, the crushed empty can 14 can be automatically put into the nylon bag 15 set below through the outlet 43 formed by the distal end portion of the fixed plate 21 and the compression movable plate 22. It has become. The structure of the fixed plate 21 and the compression movable plate 22 necessary for this will be described.

FIG. 3 shows the operation of the movable compression plate 22a before and after compression at the compression position A at the fixed plate 21a and the movable compression plate 22a in consideration of the above. The compression movable plate 22a is formed in a U-shaped cross section, and the pin connecting portion 44 on the pin 25 side and the empty can 12 are compressed from the input port 17 to the compression position A.
And the empty can 12 is fixed to the fixing plate 21 at the compression position A.
