Description

Metal can shredder

The present invention relates to a metal can shredder, wherein after a user drinks a beverage can or coffee can at a highway rest area, etc., when the user inserts the metal can into the inlet of the metal can shredder, it is sensed by a sensor, operated through a control unit, and compressed and shredded to determine the volume. It relates to a metal can shredder that stores shortened.

In general, it is a technology that compresses bulky products such as cans and PET bottles to reduce the volume and facilitates recycling treatment.Registered Utility Model 20-0307918 is a housing that forms a predetermined internal space with an inlet formed at the top to insert empty cans. And, the first compression roller that is rotatably provided in the inner space at the lower side of the inlet and is installed at a predetermined distance from each other, the driving motor and the first compression roller for rotationally driving the second compression roller and the roller have an outer circumferential surface forming a magnetic body and the lower side Separation plate is installed on the wall and consists of a magnetic metal container for receiving magnetic empty cans and a non-magnetic metal container for receiving non-magnetic empty cans.

However, since it is a configuration that selects whether or not it is made of iron after compression, there is a problem that there is a risk of explosion in the case of gas cans and that the aluminum cans must be treated separately.

In addition, Korean Patent Publication No. 10-2014-0068749 is provided with a container input part in which an empty container is inserted and a metal detection sensor and a barcode scanner are formed, and a container whose upper part is opened to accommodate the empty container, and the empty container is rotated by a motor.

It consists of a foreign material discharge port for discharging the foreign material from the dropped empty container.

However, since this performs a collection processing function based on whether or not a barcode can be recognized, it is possible to process only when the barcode can be recognized, and thus there is a problem in that versatility is poor.

Such a conventional technique is a device for compressing cans or PET flats, and uses a barcode scanner and a metal sensor to distinguish the presence or absence of a metal material in the inlet and perform the compression treatment.

However, in recognizing barcodes, the recognition portion is limited, and if the barcode portion is damaged, it is not recognized and there is an inconvenience that new products must be continuously registered.

In addition, in the conventional technology using a metal sensor, magnetic metal and non-magnetic metal are divided and compressed, but there is a problem in that the divided aluminum can needs to be processed separately.

The present invention is to solve the problems of the prior art, and provides a metal can shredder that senses by a sensor and operates through a control unit when a user inserts a metal can into the inlet of a metal can shredder, compresses and shreds, and stores the volume by reducing the volume.
