Description

[Detailed Description of the Invention] This invention relates to a can crusher whose purpose is to crush used cans with a relatively small force.

As a conventional can crusher, a method of crushing a can by pressing a pressure plate against one end plate side of the can is known.

However, since cans are made to be strong against pressure in the vertical direction, this method has a problem in that a relatively large pressure is required to crush the can.

However, in this invention, the rotary plate and the pressure plate were placed opposite each other, so when crushing the can, a vertical force and a rotational force perpendicular to the pressure force were applied at the same time, so a relatively small force was required. This makes it possible to crush the can, thus solving the above-mentioned conventional problems.

This invention will be explained below based on the embodiments shown in FIGS. 1 to 5.

A guideway 2 for cans is vertically installed in the upper part of the housing 1, and the upper end is open to the outside and the lower end is protruded into the housing 1. The guideway 2 has a shape that guides the can horizontally. At the lower end of the guideway 2, a rotary plate 4 and a pressure plate 5 having arc-shaped can support pieces 4a and 5a for supporting the end plate side of the can 3 are installed facing each other.

The upper end of the guideway 2 is expanded into a funnel shape to form an input port 6;
The can is shaped so that it can be loaded only when it is held horizontally, and the mounting shaft 7 of the rotary plate 4 and the mounting rod 8 of the pressure plate 5 are supported horizontally and on the same straight line.

A pinion 9 is fixed to the mounting shaft 7 of the rotary disk 4, and a rack 10 is engaged with the lower part of the pinion 9.

The rack 10 is slidably supported horizontally, and a rotating cam roll 11 is attached to the base end thereof.

The rotating cam roll 11 is an inverted triangular rotating cam 1 installed on the top of a connecting rod 12 that is vertically and movably installed.
It is in contact with 3.

The rack 10 is always urged toward the rotating cam 13 by a spring (not shown), and the rack 10 is always urged toward the rotating cam 13 by a spring (not shown).
It is designed to slide left and right (in Fig. 1) as it moves up and down.

The lower end of the connecting rod 12 is fixed to one side of a pedal 15 rotatably attached to the lower part of the housing 1 via a horizontal rotating shaft 14.

The pinion 9, rack 10, rotary cam roll 11, connecting rod 12, and rotary cam 13 constitute a rotation input device for the rotary disk 4.

A separator cam 16 is provided on the top of the connecting rod 12 in parallel with the plate cam 13, and a separator cam roll 18 attached to the base end of a separator lever 17 is in contact with the separator cam 16.

The middle part of the separator lever 17 is attached to the rotating shaft 19, and the tip thereof projects slightly into the guide path 2 of the can, so that when the separator cam 16 is lowered, the separator lever 17 moves to the first position. It rotates clockwise in the figure, and its tip protrudes into the guideway to prevent cans at the lowest level in the guideway from falling.

Reference numeral 20 in FIG. 5 is a spring that biases the separator cam roll 18 toward the separator cam 16 side.

A pressure cam roll 21 is attached to one end of a mounting rod 8 vertically fixed to the pressure plate 5.
It comes into contact with an inverted triangular pressure cam 23 provided at the top of a connecting rod 22 that is vertically and movably raised and lowered.

The mounting rod 8 is constantly pressurized by a spring 28.
The pressure cam 23 is biased towards the third side, and is configured to slide left and right (FIG. 2) as the pressure cam 23 moves up and down.

The lower end of the connecting rod 23 is fixed to the other side of the pedal 15.

The mounting rod 8, the pressure cam roll 21, the pressure cam 23, and the connecting rod 22 constitute a sliding input device.

In the figure, 24 is a pedal stopper, 25 is a collection door, 26 is a partition floor, and 27 is a spring that lifts the pedal 15 to the flip-up position.

Next, the operation will be explained based on the above embodiment.

The pedal 15 is pulled upward by the spring 27, and in this state, the rotary disk 4 and the pressure disk 5 are in an open state with the guide path 2 in between, as shown in FIG.

Here can 3.3a. 3b into the guideway 2, the lowermost can 3 is attached to the support pieces 4a and 5a of the rotary plate 4 and the pressure plate 5.
Supported by

Next, when the pedal 15 is depressed and rotated as shown by the arrow 31, the connecting rods 12 and 22 are lowered as shown by the arrows 32 and 33, respectively.

As the connecting rod 12 descends, the rotating cam 13 descends and the third
As indicated by the arrow 34 in the figure, the rack 10, one end of which is brought into contact with the rotary cam 13, moves horizontally in the direction indicated by the arrow 35 in FIG.

Therefore, the pinion 9 meshed with the rack 10 rotates in the direction of arrow 29 in the figure, and the rotary disk 4, which is coaxially fixed, also rotates in the same direction.

On the other hand, as the connecting rod 22 descends, the pressure cam 23 descends (arrow 36 in FIG. It horizontally slides along the cam wall 23 in the direction of arrow 37 in FIG.

Therefore, the pressure plate 5 fixed to the tip of the mounting rod 8 comes close to the rotary plate 4 and crushes the can 3 sandwiched between the two plates.

As described above, when the pedal 15 is depressed, the rotary disk 4 rotates and applies twisting force to the can, and the pressure disk 5 moves in the direction of the rotary disk 4 and pressurizes the can from above and below, so that the can 3 is easily crushed.

Here, the can 3a at the lowest stage in the guideway 2 is rotated as shown by the arrow 38 in FIG. 5 by the separator cam 16, which is lowered as shown by the arrow 30 in FIG. 5 as the connecting rod 12 is lowered. Since it is supported by the tip of the separator lever 17, it does not move downward.

Next, when the pressing force of the pedal 15 is removed and the pedal is returned to its old position, the rotary cam 13 and the pressure cam 23 are raised, the rotary disk 4 is rotated in the opposite direction, and the pressure disk 5 is moved to the position shown by the arrow 39 in FIG.
Move like this and return to the old position.

Therefore, the distance between the rotary plate 4 and the pressure plate 5 is widened, and the crushed cans fall.

Similarly, the separator lever 17 also returns to its old position as the separator cam 16 rises, so the can 3a at the lowest stage in the guideway descends and is supported by the support pieces 4a and 5a of the rotary plate 4 and the pressure plate 5. be done.

Incidentally, the same effect can be obtained by providing a push-down handle at an appropriate height in place of the pedal 15.

Next, the embodiment shown in FIGS. 6 and 7 uses a motor as a power source, and the lower end of the connecting rod 12.22 is fixed to both ends of the rotating shaft 41 on a rotating plate 42.42a.
A chain 46 is installed between a sprocket wheel 43 fixed to the rotating shaft 41 and a sprocket wheel 45 fixed to the rotating shaft of the motor 44 by pins.

In the figure, 47 is a limit switch for controlling the rotation of the motor, and 48 is a control plate fixed to the rotating shaft 41 for connecting and disconnecting the limit switch.

In each of the above embodiments, the vertical motion of the connecting rod 12.22 is converted into horizontal motion or rotational motion by a cam or a combination of a cam, rack and pinion, but the input device is limited to that of the above embodiments. isn't it.

For example, the rotary shaft of the motor is directly connected to the rotary disk 4, and the pressure plate 5
The piston rod of the cylinder may be directly connected to the cylinder, and the point is that it is sufficient to be able to impart rotational motion to the rotary disk 4 and give sliding motion to the pressure plate 5.

Further, the rotary plate 4 and the pressure plate 5 can also be installed facing each other in the vertical direction.

Furthermore, according to the above embodiment, since the separator lever 17 is provided, even when a plurality of cans are thrown into the guideway 2 at once, they can be crushed one by one, which is efficient.
A separator lever or other separator is not required if each piece is to be added one by one.

It goes without saying that the rotary disk may also be moved and rotated in the rotating direction.

That is, according to this invention, since the rotary disk and the pressurizing disk are placed opposite to each other, it is possible to crush the can by giving it a twist and pressurizing it, which has the effect of crushing the can with a relatively small force.
