Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for crushing empty cans such as juice cans and beer cans to sort and collect them according to tube material. Regarding

[0002]

2. Description of the Related Art Empty can compressors are used to crush empty cans for recycling. At this time, even if aluminum cans and steel cans are supplied in a mixed form, it is necessary to distinguish between them and collect the cargo. Therefore, normally, the crushed cans are further sorted.

[0003]

In such an apparatus for separately performing crushing and sorting, the steps have two apparatus configurations, and even if they are simply combined, a large apparatus is required.

Further, in the recycling process, empty bottles may be mixed in empty cans, and if an empty bottle is put into the compressor, the compressor will be damaged.

Further, if the empty can is caught during the movement in the compressor, the processing of the subsequent empty can becomes a problem.

Moreover, when the empty can is crushed, the liquid, which is the residual content, may be discharged and the surroundings of the compressor may be soiled.

The present invention has been made in consideration of the above points, and an object thereof is to provide the following empty can compressor. That is, the first object is to provide an empty can compressor which is not damaged even if foreign matter that is difficult to compress is mixed.

A second object is to provide an empty can compressor which allows the empty can to move smoothly in the compressor.

A third object is to provide an empty can compressor capable of appropriately containing the residual contents of the empty can.

[0010]

In order to achieve the above object, in the present invention, firstly, an empty can that has been charged is moved along a predetermined path and guided to a press to be crushed, and then, depending on the presence or absence of magnetism. In an empty can compression / sorting machine that sorts and discharges to each discharge path, the press includes a fixed plate having magnetism, and a pair of presses provided on both sides of the fixed plate for electromagnetically adsorbing and holding the fixed plate. A movable plate that sandwiches an empty can supplied through the predetermined path between the electromagnet and the fixed plate by moving the movable plate toward and away from the movable plate, and then compresses the empty can with the fixed plate; And a drive source for driving the empty can compression and sorting machine, and secondly, the empty can that has been introduced is moved along a predetermined path by a guide member to be guided to the press and crushed,
Then, in the empty can compression / sorting machine that sorts according to the presence or absence of magnetism and discharges toward each discharge path, the guide member has a passage member having one end connected to the press and an uneven structure on the lower surface. And a support member that is in contact with the portion of the passage member having the concavo-convex structure and that supports the passage member so as to be movable in the longitudinal direction with rocking, and provides an empty can compression sorting machine, Thirdly, in the empty can compression sorter for moving the inserted empty cans along the predetermined path by the guide member, guiding them to the press and crushing, and then sorting according to the presence or absence of magnetism and discharging to each discharge path. The guide member is formed in a semi-cylindrical shape so that the connection end with the press is smooth and the gap is minimized. In the empty can compression sorter that guides the inserted empty cans along a predetermined path, then crushes them, then sorts them according to the presence or absence of magnetism and discharges them toward their respective discharge paths, the discharge path is made of magnetic material. There is provided an empty can compression / sorting machine having two receiving surfaces which differ depending on the presence or absence, and a mountain-shaped partition plate having a large number of small holes formed in these receiving surfaces.

[0011]

In the first aspect of the invention, the supporting force of the fixing plate is adjusted by adjusting the current flowing through the electromagnet supporting the fixing plate of the press.

In the second aspect of the invention, when the guide member is moved in the longitudinal direction thereof, the guide member swings up and down due to the interaction with the support member on the uneven structure on the lower surface. Due to this swinging, empty cans that have become hard to fall into each other in the guide member and that are difficult to fall off or are caught can be smoothly passed.

According to the third aspect of the invention, the connecting end of the guide member to the press is formed in a semi-cylindrical shape so that the gap is as small as possible with respect to the crank movement, and the empty can is prevented from catching. Empty cans move to the press smoothly.

According to the fourth aspect of the invention, since the compressed empty can has the mountain-shaped partition plate having two faces with small holes corresponding to each drop path distributed according to the presence or absence of magnetism, the remaining contents of the can are It is dripped downward through this partition plate and stored in a container or the like arranged below the partition plate.

[0015]

According to the first aspect of the present invention, the supporting force of the fixed plate of the press can be adjusted by the attractive force of the electromagnet, and even if something that cannot be compressed is bitten, the fixed plate will allow it to escape, preventing damage to the compressor. .. In this case, it is easy to select the limit point between the crushable foreign matter and the normal empty can.

According to the second aspect of the present invention, the guide member is moved in the longitudinal direction in accordance with the operation of the press and is accordingly swung in the vertical direction, so that the empty can guided by the guide member may be caught in the middle. None, and even when they are collectively thrown into the guide member, they are destroyed by the swinging action and thrown into the press.

According to the third aspect of the invention, the empty can smoothly moves to the press without being hooked at the connecting portion from the semi-cylindrical portion at the end of the guide member, and the empty can is satisfactorily compressed.

According to the fourth aspect of the invention, since the mountain-shaped partition plate having two receiving surfaces with small holes is arranged in the most efficient discharge passage of the compressed can, the residual contents of the can pass through this partition plate. Can be stored in a container below the partition plate.
