A method and apparatus are provided for crushing and sorting cans to collect waste cans in an optimal weight-to-volume ratio are provided. The method includes determining whether or not an object is supplied to a can crushing device and whether or the supplied object is a can by a proximity sensor installed at a can supply unit, and when it is determined that the supplied object is a can, opening an opening/closing plate installed at the can supply unit, thereby supplying the can into a crushing/sorting/discharging unit, and crushing/sorting/discharging for crushing the supplied can by a crushing plate installed in the crushing/sorting/discharging unit, sorting the crushed can using an electromagnetic force applied to the crushing plate by electromagnets mounted on the crushing plate, in accordance with the material of the can, and then discharging the sorted can.

1. Field of the Invention
The present invention relates to a method and apparatus for crushing and sorting cans to collect waste cans in an optimal weight-to-volume ratio or in a minimum volume-to-weight ratio, and more particularly to a method and apparatus for crushing and sorting cans, using a simple construction and a minimum number of processing steps.
2. Description of the Related Art
The above objects, and other features and advantages of the present invention will become more apparent after a reading of the following detailed description when taken in conjunction with the drawings, in which:
FIG. 1 is a block diagram illustrating sequential processing steps of a can crushing and sorting method according to the present invention;
FIG. 2 is a perspective view illustrating a can crushing and sorting apparatus according to the present invention;
Now, preferred embodiments of the present invention will be described in detail with reference to the annexed drawings.
FIG. 1 is a block diagram illustrating sequential processing steps of a can crushing and sorting method according to the present invention.
In accordance with this can crushing and sorting method, emptied cans are crushed and sorted using a can crushing device to which those cans are supplied. As shown in FIG. 1, the can crushing and sorting method according to the present invention involves an object determining step S1 for determining whether or not an object is supplied, and then whether or not the supplied object is a can or a foreign matter; a can supplying step S2 for if it is determined that the supplied object is a can, supplying the can into the can crushing device; and a can crushing/sorting/discharging step S3 for crushing the supplied can by a crushing plate installed in the can crushing device, sorting the crushed can using an electromagnetic force applied to the crushing plate in accordance with the material of the can, and then discharging the sorted can.
