Description

[0001]
[Industrial application fields]
The present invention relates to a vibration sorting apparatus, and more particularly, for sorting and removing lightweight materials such as films and sheets from a mixture of lightweight materials such as films and sheets and heavy materials such as glass bottles and metal cans. The present invention relates to a vibration sorting device.
[0002]
[Prior art and its problems]
In recent years, glass bottles and metal cans discharged from ordinary households have been separately collected as recyclable resource waste, mainly in bags such as plastic films and sheets. In order to turn glass bottles and metal cans into recycling, first break the bags by putting the bags of plastic films, sheets, etc. in these pieces into a bag breaking machine, and then use them as broken pieces that interfere with the sorting and collection process of glass bottles and metal cans. Film sheets are removed. However, an apparatus suitable for sorting films / sheets and glass bottles / metal cans has not yet been developed, and even the latest sorting plants rely on manual work.
[0003]
General waste discharged from expressway service areas, theme parks, transportation, etc. includes glass bottles, metal cans, lunch boxes, paper bags, newspapers, etc., but is also collected in plastic film bags. In these cases, the plastic films, sheets and papers are removed as combustible materials after the bag is broken.
[0004]
As a sorting apparatus for these films and sheets, there is "Trommel screen" according to Japanese Utility Model Publication No. 61-187276. In this method, dust is put into a drum having a sieve mesh on the peripheral side surface, and glass waste and vinyl sheet are selected. Further, in the “waste material sorting device” according to Japanese Patent Laid-Open No. 4-267977, the waste material is supplied onto an inclined belt having a large number of holes that move upward, and a suction chamber is provided on the lower surface of the belt at the supply position. A belt conveyor that applies ultrasonic waves to the belt is disclosed. That is, it is a belt conveyor sorting device in which a lightweight object such as a vinyl sheet is attracted by a belt and moved upward, and a heavy article is sorted by moving the belt downward by its own weight. In addition, a method of scooping up film sheets with comb teeth is also conceivable, but this is not necessarily a preferable method because the apparatus becomes complicated including a method of vacuum suction.
[0005]
[Problems to be solved by the invention]
The present invention has been made in view of the above-described problems, and an object thereof is to provide a simple vibration sorting device for sorting and separating lightweight materials such as films and sheets from heavy materials such as glass bottles and metal cans.
[0006]
[Means for solving problems]
The above purpose is to arrange a plurality of sieving bars extending in a slightly downward slope toward the downstream side in parallel in the vibration trough, and use heavy items such as glass bottles and metal cans as sieving units to remove lightweight items such as films and sheets. A sieve unit having a fixed sieve opening on the sieve is formed, and a sieve unit in which a bowl-like sieve transfer truck is provided at a predetermined length directly below each of the sieves is provided with a downward step. The downstream end of the sieve unit of the upper sieve unit is arranged in cascade in the downstream side and extends directly above the upstream end of the lower sieve unit, and the upper lower sieve unit A vibration sorting device for films and sheets, characterized in that a gap for dropping heavy objects such as glass bottles and metal cans is provided between the downstream end of the transfer truck and the upstream end of the lower sieving transfer truck. , Achieved by.
[0007]
[Action]
Lightweight items such as films and sheets are transported on the sieve surface formed by the multiple sieve rods of the sieve unit in the vibration trough, and even if there are parts that hang down into the sieve openings, they are transferred by the sieve transfer truck. Since it is received, it is transferred to the downstream end without falling off. On the other hand, heavy items such as glass bottles and metal cans fall from the sieve surface and are transferred to the sieving transfer truck, and the downstream end of the sieving transfer truck in the upper sieving unit and the upstream end of the sieving transfer truck in the lower sieving unit It falls further from the gap between. In this way, lightweight items such as films and sheets are selectively removed from heavy items such as glass bottles and metal cans.
