Regarding the incoming chute of the machine.

[0002]

2. Description of the Related Art With the spread of vending machines, the sales volume of cans containing soft drinks, drinks such as beer and portable foods has increased remarkably. Since leaving the used cans as they are may cause environmental pollution, for example, parks, beaches, etc., have adopted a method of collecting empty cans collected in a trash can. However, if the trash can soon becomes full of empty cans, it is easy to leave it in the surrounding area. Therefore, it is necessary to collect empty cans frequently.

Most of the volume of the empty can is occupied by air. Therefore, collecting empty cans in their original shapes and transporting them to empty can processing plants is like carrying air, and the number of empty cans that can be collected at one time is also limited. Therefore, various crushers for crushing empty cans to reduce their bulk have been developed. If these crushers are placed in a place where empty cans are likely to accumulate, the crushed empty cans can be put into the trash can, so that the capacity of the trash can is increased.

As such an empty can crushing machine, for example, a can crusher having the structure shown in FIG.
It is introduced in Japanese Patent No. 5833. This can crusher comprises a case body 10, a press unit 20 and an empty can reservoir 3
0 is set. A receiving plate 11 is stretched on the inner surface of the case body 10, which corresponds to the press section 20.

The press section 20 is provided with a foot lever 22 attached to the case body 10 so as to be swingable around a fulcrum 21. The auxiliary lever 24, which comes into contact with the guide surface 23 formed on a part of the lower surface of the foot lever 22, has one end supported by the shaft portion 25 and the other end connected to the link bar 26. The link bar 26 forms a link mechanism together with the toggle bar 27 and the support plate 28. A lower end of the support plate 28 is connected to the case body at a fulcrum 21, and a push plate 29 is stretched on a surface facing the receiving plate 11.

The can reservoir 30 is a crushed empty can 41, 4
A bottom plate 31 on which the 2 is placed is provided. The bottom plate 31 is swingably attached to the case body 10 via a shaft portion 32, and a push-up plate 33 is provided on the lower surface side. A fixed partition plate 34 is provided in the vicinity of the front end of the bottom plate 31, and the empty cans 41 and 42 are secured at predetermined positions on the push-up plate 33. The toggle bar 27 is bent in a V shape at a connecting portion with the link bar 26, and is connected to one end of the toggle bar 35. The other end of the toggle bar 35 is attached to the case body 10 by a shaft portion 36. Also, the lifting plate 33
Push the bottom plate 31 up via the toggle bar 2
A return spring 37 is stretched between the stepping lever 22 and the support plate 28 in order to apply an upward force to the toggle portion constituted by 7 and 35.

The crushed empty can 40 has a bottom plate 31 from above.
Thrown on. When the foot lever 22 is pushed down, the toggle portion composed of the toggle bars 27 and 35 is pulled down via the link bar 26. Therefore, the inlet 38 between the bottom plate 31 and the fixed cutting plate 34 is opened, and the empty can 42 on the bottom plate 31 falls into the press section 20. Further, the downward movement of the foot lever 22 works as an action of pressing the push plate 29 toward the receiving plate 11 by the link mechanism including the link bar 26, the toggle bar 27 and the like. Therefore, the empty can 43 sent to the press section 20 is crushed between the receiving plate 11 and the pressing plate 29. The crushed empty can 44 is taken out from the case body 10 by opening the discharge plate 12. Then, by repeatedly depressing the stepping lever 22, the empty cans put on the bottom plate 31 are sequentially crushed and taken out from the discharge part.

[0008]

When crushing empty cans using this crushing machine, the number of empty cans fed from the inlet 38 to the press section 20 is not constant. In particular, if the empty cans 41, 42 on the bottom plate 31 have different sizes,
The number of empty cans sent to the press section 20 greatly varies. Therefore, the force required when the foot lever 22 is pushed down to crush the empty can greatly fluctuates, and in some cases, the empty can 43 fed into the press section 20 is not crushed and is caught on the inner wall of the case body 10 or the like. There are also cases.

In the temporary holding space 38a located at the inlet 38, the sent empty can 43 stands upright,
It may fall between the receiving plate 11 and the push plate 29 in the upright state. In such a case, the force applied to the upper portion and the lower portion of the empty can 43 are different, and the empty can 43 cannot be crushed in a state where the volume of the empty can 43 is sufficiently reduced.

Further, in the crushing machine having the structure shown in FIG. 1, the crushed empty can cannot be moved to the next crushing operation while being left under the press section 20. Therefore, the discharge plate 12
The work of opening the discharge port 13 to open the discharge port 13 is required every time the crushing is performed, and the crushing work itself becomes troublesome.

Therefore, the inventors of the present invention have found that the crushed empty can drops downward between the receiving plate and the push plate so that the crushed empty can is automatically discharged, and the container such as a basket. We developed an empty can crusher that can be housed in a building and applied for a patent separately. In this type of crushing machine, it is an important problem to reliably feed the empty cans one by one between the receiving plate and the pressing plate. Also, if the empty can is clogged during the feeding process, the crushing work itself cannot be performed. In particular, in the case of a beverage can having leftover drinks remaining, it easily adheres to the inner wall of the device, which hinders smooth delivery. Further, the feeding portion is deformed by an external force or the like, and the empty can is easily clogged.

The present invention was devised to solve such a problem, and by providing a reinforced feeding chute along the handle pipe, the deformation resistance is increased and an empty can is clogged inside. It is an object of the present invention to provide an inflow chute for empty cans crushing machine that can prevent the above-mentioned problems and can feed empty cans to the crushing unit one by one.

[0013]

In order to achieve the object, the feeding chute of the present invention is provided with a push plate that is pressed against a receiving plate that is passed over a pair of left and right fixing plates that are erected from a pedestal. A movable arm is swingably attached to a shaft portion provided on the fixed plate, and the empty can is crushed by pressing the pressing plate against the receiving plate while sandwiching the empty can,
In the crushing machine in which the empty can that is crushed when the pressing plate separates from the receiving plate is discharged from the gap at the lower end side of the receiving plate and the pressing plate, on both side base members constituting the pedestal part. Both ends are fixed, the central part is erected from the base member, the handle pipe has a grip portion, the reinforcing frame fixed to the handle pipe, and the reinforcing frame is inserted into the upper and lower empty can inlets, respectively. And a feed chute having a lower end opening, the lower end opening being disposed at a position where it can be closed by the empty can receiving plate of the movable arm.
