Description

[Detailed description of the invention] The present invention relates to a press machine for compressing empty cans.

Suitable for crushing relatively small empty cans of juice, cola, soft drinks, foodstuffs, etc.

Recently, air can pollution in particular has been attracting a lot of attention as a social problem, but as it continues to be treated as a last-minute measure, it is not only damaging the aesthetic beauty of the environment, but has also developed into a problem that is causing the destruction of nature.

Therefore, if a press machine that can easily crush empty cans by hand is always available at retailers and consumers, it would ultimately prevent empty cans from being left unattended, and this would be an effective measure to prevent pollution. be.

For this reason, various small press machines have been proposed, but because the feeding device is incomplete, the empty can for one piece is not crushed reliably, and multiple pieces are fed between the machine frame and the press plate at one time. Problems still remain, such as it being impossible to crush by hand, people getting injured during crushing, and others not being sent at all and ending up empty firing.

Therefore, the present invention aims to solve each of the above-mentioned problems by providing a feeding device that can reliably feed one piece.

The structure of the present invention is that the tilting plate is pivotally mounted at a suitable position above the machine frame, and the foot-operated pedal and the tilting plate are connected by a link mechanism, so that when the pedal is in the raised position, the tilting plate is tilted backward toward the empty can inlet side. The empty can is then placed between the entrance plate and the inclined surface rearward from its fulcrum, and the empty can is placed in a substantially horizontal state in the lowered position over a predetermined gap formed between the front end and the rear end of the press plate. was placed on the machine, and during the return from the lowered position to the raised position, the front end of the tilting plate tilted slightly backwards raised the empty can to feed it between the machine frame and the press plate.

A tilting plate pivotally connected between the inlet plate and the press plate is linked with the pedal operation to create a material that can reliably feed one piece.

The advantage of this feature is that it is possible to feed one piece with the Sealy movement of the tilting plate, which has a simple structure that interlocks with the petal, so there is no need for separate manual operations for feeding, and the operator only has to perform foot operations from start to finish. work safely, reliably, and quickly.

In addition, since it uses gravity, it does not require any special power equipment, is lightweight, compact, easy to carry, requires less space for installation, and has great practical effects.

Embodiments of the present invention will be described below with reference to the drawings.

The fuselage body 10 is made of a suitable steel frame material, and the side plates 11 are fixedly installed on both sides of the fuselage body 10.

Reference numeral 12 denotes a petal 14 which is pivotally attached downwardly to the central column 13 of the fuselage 10, and has a U-shaped cross section, into which an outer race 16 of a ball bearing 15 is slidably fitted.

Reference numeral 18 denotes a bell crank lever, which is pivotally mounted 19 at substantially the center of the upper and lower parts of the central column 13, and a pin 20 implanted at its rear end is tightly fitted into the inner race of the bearing 15.

In addition, a ball bearing 21 is installed at the front end of the lever 18.
is pivotally mounted 22, that is, the inner race 23 of the bearing 21 is tightly fitted to the pivot pin 22, and the outer race 24 rolls via the ball bearing 21 with respect to the pivot pin 22 protruding from the front end. It is freely configured.

Further, the rear end of the petal 12 serves as an operating end 25, and the pivot points 14 and 19 serve as lever fulcrums.

Reference numeral 26 denotes a press plate, whose lower part is swingably pivoted below the front pillar 27 of the fuselage 10, and has a front face 29 and a back face 30 extending upward from the pivot point, and the upper part is the rear part. That is, it is bent into a dogleg shape on the bell crank 18 side, and has a free rear end.

Furthermore, an inclined table 32 is welded to the upper rear surface of the press plate 26 so that the outer race 24 of the bearing 21 can be continuously rolled and displaced from the upper surface of the rear surface 30 to the inclined table 32. The press plate 26 is designed to tilt further forward when the outer race 24 is located above.

(For the same angular displacement of petal 12 hand).

33 and 34 are tension springs, and one end of 33 is attached to the press plate 2.
The other ends of 6 and 34 are respectively locked to the central pillar 13 to constantly urge the press plate 26 in the clockwise direction, and one end of 34 is locked to a stop plate 35 fixed to the central pillar 13, and the other end is locked to the petal 12, respectively. The pedal 12 is always biased counterclockwise.

Reference numeral 36 denotes a pressure receiving wall fixed to the side plate 11 in the vertical direction at a position corresponding to the press plate 26, and a space 37 is formed between the lower end of the wall and the lower part of the fuselage 10 in which the crushed empty can can be dropped and discharged. has been done.

Reference numeral 38 denotes an entrance plate, which is fixed at an angle above the rear end of the side plate 11 with a slight forward downward slope, and has a front end 39.

40 is a tilting plate that connects the front end 39 of the entrance plate 38 and the press plate 2.
between the rear end 31 of 6 and the side plate 11,
It can swing freely around it.

The front end 42 of the tilt plate 40 is operatively connected to a slightly rearward portion 44 of the pivot point 19 of the bell crank 18 via a connecting link 43, and the tilt plate 40 is tensioned between the rear end 45 and the stop plate 35. It is always biased clockwise by a tension spring 46 provided.

With the structure described above, if, for example, small-diameter youth aluminum empty cans A and B are placed on the entrance plate 38 in the pre-operation state shown in Figure 1, they will fall into the cabin due to the downward slope to the left (front). Empty can A rolls under the force of gravity with its own weight, and stops on the slope of the tilting plate 40 that is tilted downward to the right (backward), and then B comes into contact with A and on the entrance plate 38. They will stop and wait in line. (Illustration omitted).

Now, next, the operating end 25 of the pedal 12 is pressed against the spring 34.
When one foot is placed on the pedal and a force F is applied, the petal rotates clockwise, revolves clockwise around the rear end pin 20 of the bell crank 18, and the outer race 16 of the bearing 15 is shaped like a petalco. It moves toward the pivot 14 while rolling within the channel.

Therefore, since the pivot pin 22 also revolves clockwise around the pivot shaft 19, the outer race 24 of the bearing 21 rolls and displaces from the top of the back surface 30 to the top of the inclined table 32, and when it is finally displaced to the vicinity of the top. , the front side 2 of the pressure receiving plate 36 and the press plate 26
Crush the empty can C fed into the wedge-shaped chamber 47 between 9 and 9 in the previous process.

That is, it is displaced from FIG. 1 through FIG. 2 as shown in FIG. 3.

What should be noted here is the operation of the tilting plate 40.

When the state shown in FIG. 1 shifts to the second state of the petal shown in FIG. The empty can A is moved forward by the gravity of the following empty can B, and the empty can A is in a state of straddling the space 48 formed by the front end 42 of the tilting plate 40 and the rear end of the press plate 26. Displaced due to stress.

The crushing work is completed in the state shown in FIG.

Next, if you reduce or remove the pedal force from the pedal 12, the spring 34
With the restoring force, the petal 12 is rotated counterclockwise as shown in the third figure, and the bell crank 18 is also rotated counterclockwise via the bearing 15, and the connecting link 43 is lifted. The outer periphery of the empty can A is pushed up by the front end 42 of the tilting plate 40, and after going through the state shown in FIG. When the container falls to the position of the empty can C shown in the first figure, the return work is completed.

From then on, the above operations can be repeated, and the work progresses while repeating the steps of waiting, moving, and crushing each empty can.

Of course, if you crush many empty cans continuously, you will need to refill them from the entrance separately.

In addition, in Figures 4, 5, and 6, the part of the feeding mechanism that constitutes the main part of the present invention is the same as in Figures 1, 2, and 3 above, but other examples of applications in which the structure and function of the bell crank are provided are shown. shows.

That is, one end of the link 54 is pivotally attached 53 to a suitable position near the pivot point 52 of the petal 51, and the other end of the link 54 is pivotally attached 53 to the rear end of a bell crank 55 corresponding to the bell crank 18.
6 has been done.

As in the previous example, when the pedal 51 is depressed, the pedal 51 rotates clockwise around the pivot 52, and the motion is transmitted to the bell crank 55 via the link 54,
The bearing 21 is rotated clockwise around the bearing 21, causing the bearing 21 to roll. The following operations are the same as those in the previous example, and the return process has the opposite effect to that described above, and the other structures and operations are all the same and will not be described further.
