JPH091395A - Mechanism for sorting can material in waste can crusher - Google Patents

Abstract

PURPOSE: To continuously sort the material of a crushed waste can by attaching a revolving plate freely rotatably without being interfered by the rotation of a roller. CONSTITUTION: A crushed aluminum can is transported to a rotary plate 6 by means of a turning belt 8 and an extruding plate 7 and magnetically separated by a magnet 5. Unattracted by the magnet 5, the aluminum can is transported to a falling position and dropped into an aluminum can container. A crushed steel can is transported to the rotary plate 6, attracted by the magnet 5 attached to the rotary plate 6, turned halfway round a roller 4 and dropped into a steel can container in the lower part of a mechanism 1 for sorting materials. Since the crushed steel can is transported vertically, its contact area on the rotary plate is large, thereby eliminating erroneous sorting such as fall-off of a can caused by an insufficient magnetic force. The residual liquid is led to a gutter and collected. Thus, the power source may be reduced, enabling to save energy.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an empty can crushing device, and more particularly to a material sorting and sorting mechanism for crushed and reduced volume empty cans for beverages.

[0002]

2. Description of the Related Art As a material selection mechanism for an empty can crushing device according to the prior art, as shown in Japanese Patent Laid-Open No. 63-311959, an empty can after pressing is dropped on a conveyor to select the material. After that, it was confirmed by a sensor that an empty can on the conveyor was put in the recovery box under the conveyor, the sorting unit was positioned after a certain period of time, the conveyor was stopped, and then the pressing was performed again.

Further, as a method of selecting empty cans that are continuously conveyed, a magnet is installed in a roller of a conveyor to perform selection.

[0004]

Since the material selecting mechanism of the conventional empty can crushing device confirms that an empty can enters the collecting box for each press and positions the selecting section continuously, It was not possible to sort, and it was not possible to sort a large number of empty cans in a short time.

Further, in the method of selecting magnets by attaching them to the rollers of the conveyor, when the steel cans are stacked on the aluminum cans and attracted to the magnets, the aluminum cans are not properly selected and confused with the steel cans. there is a possibility.

An object of the present invention is to provide a material selection mechanism capable of continuously selecting aluminum cans and steel cans without erroneous selection.

[0007]

A material selection mechanism for an empty can crushing device according to the present invention has a gap having a crushing width of the empty can, and a guide for forcibly standing and aligning the crushed empty can is conveyed. Mesh belt with an extruded plate for rotation, rollers for rotating the belt, and a rotary plate with permanent magnets attached to the rotary shafts on both sides of the roller. It becomes possible by rotatably mounting without being interfered with.

[0008]

The material selection mechanism of the empty can crushing device according to the present invention is
The guides below the crushing section enable the crushed empty cans to be conveyed in a row, and the rotary plates with permanent magnets rotatably mounted on both sides of the roller at the leading end in the conveying direction are used for sorting. Only steel cans can be reliably attracted by magnets from the crushed / conveyed empty cans, and erroneous selection of aluminum and steel cans can be prevented. Moreover, since the materials can be continuously selected, the time required for crushing and selecting a large number of empty cans can be shortened.

Embodiments Embodiments will be described below with reference to the drawings.

FIG. 1 is a perspective view of a material selection mechanism of an empty can crushing device according to the present invention.

The material selection mechanism 1 includes a frame 3 to which a guide 2 having a width that allows a crushed empty can to enter only vertically is mounted between a frame 3 and two rollers 4 and a permanent magnet 5 so that the material can be rotated freely. A plate 6 is attached. A mesh belt 8 having extrusion plates 7 attached at equal intervals is wound around the two rollers 4. Further, a gutter 9 for collecting the residual liquid dropped at the time of crushing is attached to the lower portion of the frame 3 with the traveling direction of the belt 8 inclined upward. Belt 8
Rotates by rotating the roller 4 with a power source 10 such as a motor.

If the aluminum can is crushed and enters the material selecting mechanism, it is conveyed to the rotating plate 6 by the rotating belt 8 and the pushing plate 7 and is magnetically selected by the magnet 5.
Since the material of the aluminum can is not a magnetic substance, it is not attracted to the magnet 5 of the rotating plate 6 and is transported to the dropping position as it is and dropped into the aluminum can container in the front in the transport direction.

Next, when the steel can is crushed,
Like the aluminum can, it is transported to the rotating plate 6, but since the steel can is a magnetic substance, the magnet 5 attached to the rotating plate 6 is used.
Is passed through the aluminum can drop position as it is adsorbed, and is dropped halfway around the roller 4 into the steel can container below the material selection mechanism 1. Here, since the crushed empty can is conveyed in a vertical state, the adhesion area to the rotary plate 6 becomes large, and erroneous selection such as dropping of the can due to insufficient magnetic force can be eliminated. In addition, since the residual liquid dropped during the crushing falls into the gutter 9 below the sorting mechanism, the residual liquid can also be collected.

FIG. 2 shows a sectional view of the material selecting mechanism of the present invention in which the roller 4 and the rotary plate 6 are mounted.

A bearing 11 for smoothly rotating the roller 4 is attached to the frame 3, and the shaft portion of the roller 4 is inserted into and supported by the bearing 11. Frame 3
A rotary plate 6 to which a magnet 5 is attached is inserted into a shaft between the roller 4 and the roller 4 via a bearing 12. Further, a spacer 13 is inserted between the rotary plate 6 and the roller 4 so that the magnet 5 and the roller 4 do not interfere with each other. Thereby, the rotary plate 6 can freely rotate without being interfered with by the rotation of the roller 4.

The compressed empty can carried by the belt 8 and the extruding plate 7, if it is a steel can,
The magnet 5 is attracted to the magnet 5 of the rotary plate 6 and is carried to the lower side of the roller 4, the adhesion area of the magnet 5 is gradually reduced, and the belt 8 is smoothly cut off in the traveling direction. As a result, it is possible to reduce the output capacity of the power source 10 such as a motor as compared with a structure in which the rotary plate 6 and the magnet 5 are fixed or simultaneously rotated.

FIG. 3 is a side view of an embodiment of an empty can crushing device having a material selection mechanism according to the present invention.

The empty can crushing device 20 includes a hopper 21 capable of storing a large amount of empty cans at one time, a transfer device 22 for transferring empty cans, and a heavy object sorting mechanism 23 for selecting cans and other heavy objects. , A crushing mechanism 24 for crushing empty cans, a material selection mechanism 1 for selecting empty cans by material, a residual liquid receiver 25, and storage containers 26a, 26b, 26c for storing the selected empty cans.

Here, the empty cans that have entered the hopper 21 are carried to the upper part of the device by the carrying device 22 and dropped to the heavy goods sorting mechanism 23 which sorts into cans and heavy goods other than cans. The bins and empty cans sorted by the heavy-weight sorting mechanism 23 are discharged into the foreign matter container 26a by the duct 27 below the heavy-weight sorting mechanism 23. Further, the empty can enters the crushing mechanism 24 in front of the heavy object sorting mechanism 23 and is crushed. The empty cans that are crushed and dropped are guided by the guide 2 in the vertical direction to the material selection mechanism 1, are sorted into aluminum and steel cans, and are discharged into the respective storage containers 26b and 26c. At this time, the residual liquid dropped during canning into the hopper 21, during transportation by the transport device 22 and during crushing is collected by the residual liquid receiver 25 below the hopper 21 and the material selection mechanism 1, respectively.
Collect in the residual liquid collecting container 28.

【The invention's effect】

(1) Since the crushed empty cans are conveyed in a line by the guide and are sorted by the rotatable magnets in the front in the transport direction, the material can be continuously sorted.

(2) Since the empty cans crushed by the guides are conveyed vertically, the area of attraction to the magnets is increased, and aluminum / steel cans can be reliably selected.

(3) Since the magnet is rotatably attached and the load for rotating the conveyor belt is small,
The power source can be reduced, and labor can be saved.
