JPH0929120A - Can shredder provided with chip selector - Google Patents

Abstract

PROBLEM TO BE SOLVED: To automatically select and recover chips in a scrap iron container box and scrap aluminum container box by arranging a chip selector for selecting and recovering an iron material into one container box by magnetism and an aluminum material into another container box under a cutter device. SOLUTION: A can K falls down between a can fall guide plate 4 and a conveying belt moving downward 7, and is forcibly transferred downward by the conveying belt 7. At this time, the conveying belt 7 is rotated anticlockwise around a pulley shaft by a can pushed downward, and the can K falls down onto a drum cutters 9, 10 and is cut. Chips 20 falls to the upper right part of a sleeve 25 of a magnet drum 22 by a chute 21. A nonmagnetic body such as aluminum and nonferrous metal passes thorough the sleeve 25 without being influenced by a magnet 24 and falls down into a nonmagnetic body container box below the right side. A magnetic body such as iron is attracted by the magnet 24 and is attracted onto the sleeve 25. When it passed the highest part, it is not influenced by the magnet 24 and falls down into a magnetic body container below the left side.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a can in which a chip sorting device for discriminating iron material and aluminum material magnetically is installed by injecting an iron can and an aluminum can indiscriminately and cutting them with a cutter. Regarding shredder.

[0002]

2. Description of the Related Art Heretofore, a can shredder has been known in which an iron can and an aluminum can are indiscriminately charged and cut by a pair of cutters. There is also known a can shredder that separates iron cans and aluminum cans and cuts and collects them separately.

[0003]

In the above prior art,
In the former, the iron can and the aluminum can are indiscriminately cut and both chips are stored in a mixed state, so after removing the chips,
Since the sorting work has to be done by separate sorting devices, the latter has the problem that the aluminum cans are mixed in the iron scraps and the aluminum scraps cannot be properly sorted and collected. .

[0004]

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems, and an iron material is magnetically provided below a pair of cutter devices for cutting cans into which materials are indiscriminately inserted through a can inlet. One of the storage boxes is provided with a chip sorting device for sorting and collecting the aluminum material into the other storage box inside the main body.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Specific embodiments of the present invention will be described below with reference to the drawings. Reference numeral 1 denotes a housing, on the upper part of which a can receiving portion 2 is arranged by a hinge 3 so as to be swingable outward. A can drop guide plate 4 is obliquely arranged below the can receiving portion 2, and an opening / closing plate 5 is attached to a lower portion of the can receiving portion 2 by a hinge 6 so as to open outward with a constant force. A plurality of conveyor belts 7 are arranged substantially vertically so as to face the can drop guide plate 4, and are arranged so as to be swingable about an upper pulley shaft 8. The space between the upper part of the conveyor belt 7 and the upper part of the can drop guide plate 4 is set so that the can can fall freely, and the space between the lower part of the conveyor belt 7 and the opening / closing plate 5 at the lower end of the can drop guide plate 4 cannot pass freely. It is narrow. Below the conveyor belt 7, a pair of drum cutters 9 and 10 are arranged laterally. Reference numeral 11 denotes a motor, which drives one drum cutter 9 by the belt 12 and the other drum cutter 10
Is transmitted to the upper pulley 14 of the conveyor belt 7 by the belt 13. The other end of a spring 18 pivotally attached at one end to a fixed plate 17 is fixed to a pin 16 at an intermediate portion of the support plate 15 of the conveyor belt 7, so that the pin 16 moves in an arc groove 19 of the fixed plate 17. It has become. A chute 21 for the chips 20 is arranged below the pair of drum cutters 10, a magnet drum 22 is arranged below the chute 21, and a non-magnetic material storage container 26 and a magnetic material storage container 27 are juxtaposed below the chute 21. There is. As shown in FIG. 10, in the magnet drum 22, a magnet 24 is arranged in the right half inside the fixed cylinder 23, and a sleeve 25 on the outer circumference is covered on the fixed cylinder 23 and rotated counterclockwise. The chute 21 causes the chips 20 to fall onto the right half of the magnet drum 22. In the embodiment, the rotation direction and the counterclockwise direction are set, but either may be set. The magnetism of the magnet drum may be generated by a permanent magnet or an electromagnet. The shape does not matter as long as it is a system that can sort things such as belt conveyors by magnetism instead of drums.

Next, the operation will be described. When the can receiving portion 2 on the upper part of the housing is opened outward as shown in FIGS. 6 and 7 and the can K is placed and the can receiving portion 2 is closed, the motor 11 is started. The can K falls between the can drop guide plate 4 and the conveyor belt 7 moving downward as shown in FIG. 7, and is forcibly transferred downward by the conveyor belt 7 as shown in FIG. At this time, the conveyor belt 7 is rotated counterclockwise as shown in FIG. 9 about the pulley shaft 8 by the can pushed downward, and the can K drops onto the drum cutters 9 and 10 and is cut into small pieces. The cut chips 20 fall onto the upper right portion of the sleeve 25 of the magnet drum 22 rotating counterclockwise by the chute 21 as shown in FIG.
A non-magnetic material such as aluminum or non-ferrous metal is not affected by the magnet 24, passes through the sleeve 25, and the non-magnetic material container 2 at the lower right side.
Fall into 6. The magnetic substance such as iron is attracted by the magnet 24 and adsorbed on the sleeve 25, and if it goes past the uppermost portion, the influence of the magnet 24 disappears, and the magnetic substance storage container 2 at the lower left side
It falls into 7. When a foreign object that cannot be cut, such as a bottle, is thrown in, the cutter does not easily come in, so the state is detected by a sensor, and the lock device that locks the open / close plate 5 in the closed state is turned off by turning on the DC solenoid, and the conveyor belt 7 Then, the foreign matter is pushed and the open / close plate 5 is pushed open as shown in FIG.

[0007]

According to the present invention, the iron material is magnetically stored in one of the storage boxes and the aluminum material is stored in the other storage box below the pair of cutter devices for cutting the cans that have been indiscriminately charged through the can input port. Since the chip sorting device that sorts and collects the chips is installed inside the main body, the chips can be automatically inserted even if they are indiscriminately input from the can inlet on the top of the main body without sorting iron cans and aluminum cans. The internal waste iron storage box and the aluminum waste storage box can be automatically sorted and collected, improving the recycling efficiency, and the aluminum iron can lid can also be collected in the aluminum storage box.
