Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an empty can pressing method and apparatus, and more particularly to an empty can pressing method and apparatus for simultaneously crushing a plurality of empty cans.

[0002]

2. Description of the Related Art Collecting and reusing empty cans has become a particularly important issue in the drinking water industry in recent years, and is also important in general social life from the viewpoint of optimal collection of garbage or effective use of resources. It is one of the challenges.

When transferring empty cans after collection,
Since the volume increases as it is, empty can crushing machines of various sizes are used more than before.

[0004]

On the other hand, in many conventional empty can crushing machines, since an empty can feeding press tank is arranged immediately below the press cylinder, many of them are of a type in which empty cans are loaded from the side. For this reason, in an apparatus for crushing a large number of empty cans at the same time, it is not possible to load empty cans into the empty can loading press tank, which is inefficient.

In addition, in order to improve such a situation, it is necessary to provide an empty can input port at a position close to the upper side of the empty can input press tank, that is, the press cylinder side. For this reason, if the volume of the empty can loading press tank is set to a large value, the empty can loading port inevitably becomes small, and the empty can loading operation cannot always be performed smoothly.

[0006]

An object of the present invention is to improve the inconveniences of the conventional example, particularly to enable the empty can loading work to be carried out smoothly, and to make it possible to set the volume of the empty can loading press tank to be sufficiently large, thereby performing the empty can crushing work. It is an object of the present invention to provide an empty can pressing method and apparatus for improving the efficiency.

[0007]

In order to achieve the above-mentioned object, in the invention according to claim 1, a can loading press tank whose upper and lower sides are opened is arranged on a movable press pedestal, and then empty cans are loaded from above. And a second step of moving the movable press cradle to bring the can loading press tank containing the empty cans under the press cylinder, and moving empty cans in the loaded can loading press tank. The third step of crushing the movable press pedestal at once on the automatic press cradle, and the movable press pedestal is inverted and transferred to the original position while the empty can pressing position is covered with the can charging press tank. A fourth step of discharging the empty can waste formed from the lower part of the can input press tank by a press cylinder, and a fifth step of discharging the discharged empty can waste to the outside by the movable press cradle. .

Therefore, in the invention according to the first aspect, it is possible to separately provide an empty can input area, an empty can press area, and an area for discharging pressed empty can waste, and these areas are provided. The entire empty can can be crushed at once in the process of moving the empty can, and in the empty can input area, unlike the conventional one, the press cylinder 1 is pushed to the upper side.
Since there is no, it is possible to store a relatively large number of empty cans in the can insertion press tank 3 as quickly as possible,
Therefore, a large number of empty cans can be crushed with high efficiency.

According to the second aspect of the present invention, the can charging press tank whose upper side is opened is arranged below the frame body, and the press cylinder is arranged above the can charging press tank, and the piston of this press cylinder is arranged. In an empty can pressing device in which empty can pressing means is attached to the tip of the part, the above-mentioned can loading press tank is arranged on a movable press pedestal, and
The movable press cradle is equipped with an engaging means for detachably engaging the movable press cradle and the can input press tank.

A guide rail is provided for guiding the movement of the can-inserting press tank along the reciprocating direction of the movable press pedestal and for holding the can-inserting press tank. The hydraulic press for urging the movable press pedestal to reciprocate is mounted on the frame body.

Therefore, according to the second aspect of the present invention, it is possible to carry out the above-mentioned first aspect of the present invention, and a special discharging means is provided when discharging the pressed empty can waste. Without this, the reciprocating movement of the movable press pedestal makes it possible to sequentially and automatically push the outside.

According to the third aspect of the present invention, a plurality of can-loading press tanks are provided on the movable press pedestal described above at predetermined intervals.

Therefore, according to the third aspect of the invention, as soon as the pressing process for the empty can in the one can loading press tank is completed, the pressing process for the empty can in the second can loading press tank immediately starts. Therefore, the press work for the empty cans can be performed with high efficiency as a whole.

It Then, the hydraulic cylinder 12 operates again to transfer the can loading press tank 3 to the empty can loading area in preparation for the next empty can pressing. This is shown in FIG.

Thereafter, the same steps as described above are repeated. The operation of each part described above is configured such that the main control part 11 described above issues a command in accordance with a preset program, and each part such as the hydraulic circuit 14 and the engaging means 5 operates in accordance with the command.

As described above, in the embodiment shown in FIG. 1, the empty can feeding area, the empty can pressing area, and the area for discharging the pressed empty can waste are separately provided, and the empty can moves in these areas. Since the entire empty cans are crushed at one time during the process, it is possible to crush a relatively large number of empty cans repeatedly in succession every predetermined amount. Since the cylinder 1 does not exist, a relatively large number of empty cans can be stored in the can inserting press tank 3 as quickly as possible, and therefore a large number of empty cans can be crushed with high efficiency and pressed. There is an advantage that the empty can waste A _G can be sequentially and automatically pushed out by the reciprocating movement of the movable press holder 4 without equipping a special discharging means.
