Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a method for separating and collecting bottles, aluminum cans, steel cans, plastics, etc. as recyclable waste before supplying the bottles, aluminum cans, steel cans, plastics, etc. to a sorting conveyor. , The broken small pieces of glass bottles into large pieces, glass bottles or aluminum cans,
The present invention relates to a sieving / conveying device for separating steel cans, plastic bottles, and the like.

[0002]

2. Description of the Related Art The contents of recyclable garbage collected from ordinary households, event venues, parking areas on expressways, airports, stations, ports and other appropriate places are mainly bottles, aluminum cans,
Examples include steel cans and plastic bottles. While these recyclable garbage are being conveyed on a sorting conveyor, steel cans are automatically sorted by a magnet sorter and aluminum cans are automatically sorted by an aluminum sorter, but bottles are manually sorted by color. . In recent years, bottle sorters that automatically sort bottles by color have been developed, but the mainstream is still to sort manually by color.

[0003] In the separation of bottles, if the bottles are broken too small, the sorting will be hindered. This is especially true for bottle sorters that automatically sort by color. In addition, when a large amount of small glass pieces are placed on the sorting conveyor, the purity of the sorting by the magnet sorting machine or the aluminum sorting machine is reduced, and the damage to the machine is accelerated. It is requested that the broken pieces of the bottle be removed before being placed.

Conventionally, a sieving apparatus has been mainly used for removing broken pieces of a bottle, but the sieving apparatus places a grid, a net, a plate having a large number of holes or the like on a supported frame. There is a method in which the front is inclined downward as a whole, and the frame is vibrated in the front-rear direction by a vibration motor or the like, and small pieces are sifted down when the resource waste is slid and transported forward. Also, when using a net conveyor, the idea is to remove those that are smaller than the size of the net,
It is a sieve that moves endlessly.

[0005]

The size and shape of the above-mentioned sieving apparatus and net conveyor vary widely, and the sifting device and the net conveyer can be easily fitted into the sieve or the net sieve and cannot be easily removed. In addition to the frequent occurrence, there are many troubles that various foreign matters are caught, and there is a drawback that clogging occurs in a short time. As a countermeasure against the clogging, a clogged foreign substance is removed by hand using a tool sometimes, but the clogging is immediately caused. As described above, the sieving method using eye holes has not only a fundamental drawback, but also a problem that a vibration sieve or a net conveyer cannot be mass-transported in a system and has a limitation in a processing amount.

SUMMARY OF THE INVENTION An object of the present invention is to provide a sieving / conveying apparatus which solves the above-mentioned disadvantages of the prior art, does not cause clogging, can be transported in large quantities, and can convey ropes, wires, nails and any other foreign matter. It is in.

[0007]

According to a first aspect of the present invention, there is provided a sieving / conveying apparatus, comprising: a chain conveyor having horizontal sides at predetermined intervals in a direction perpendicular to the conveying direction; Small pieces of resource waste transported by the side of the chain conveyor, which consist of vertical pieces that are cantilevered on the loading side in the parallel direction, and fall below the sieve consisting of the horizontal and vertical pieces. I am going to let it. Thus, a chain conveyor having a horizontal gap at a predetermined interval in a direction orthogonal to the transport direction, and a vertical gap at a predetermined interval supported at a loading side in a direction parallel to the transport direction at a lower portion of the transport side of the chain conveyor. As a result, while the loaded resource waste is transported to the unloading side on the side of the chain conveyor, objects smaller than the gap between the sides fall down, but at this time there is no vertical , In the case of Mr. Yoko only, thin objects even if the area is large, such as crushed and flat cans and broken pieces such as the bottom of a bottle,
When standing, even if the length of the side is larger than the gap between the sides, it will fall down. However, since a vertical member is provided below the horizontal member and the gap is narrow, the vehicle is conveyed by the horizontal member so as to slide on the vertical member without falling, and is discharged in a parabola from the unloading portion.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIGS. 5 (a) and 5 (b), a chain conveyor according to the present invention has an attachment 52 of two chains 51 with a horizontal width 53 perpendicular to the traveling direction at a predetermined interval (S _1). ), The cost is low. Further, a vertical shaft 54 provided at a predetermined interval (S ₂ ) in a direction parallel to the conveying direction below the conveying side horizontal shaft 53 of the chain conveyor is cantilevered by a loading-side support unit 55, and is connected to the lower surface of the horizontal horizontal shaft 53. The upper surface of the vertical member 54 has a slight gap or a light contact. Therefore, even if a small piece of a bottle or a foreign substance is caught between the horizontal member 53 and the vertical member 54, the horizontal member 53 is lifted up or the vertical member 54 elastically bends downward. No outage occurs.

[0009] The input of the resource refuse on the chain conveyor of the present invention may be from a discharge chute of a preceding device, for example, a shredder bag machine, or may be provided with a charging chute 56. If the drop position is correct,
It is considered that a shooting chute is unnecessary. When heavy materials are mixed in the resource waste, the input chute 56 makes one bound as shown by an arrow so that the impact of the falling object is not directly applied to the side of the chain conveyor 53, and then the chain is placed on the chain conveyor. Is preferable from the viewpoint of preventing bending of Yoko. Normally, resource garbage is not very heavy, but in areas with low segregated collection morals, things that cannot be placed, that is, things that are close to bulky garbage, may be contained. For example, not only pots and pans but also occasionally concrete lumps and bowling balls may be contained. For such heavy objects,
By once receiving and one-bound by the charging chute 56 and placing it on the chain conveyor, the chain conveyor can be prevented from being excessively designed, and the manufacturing cost can be reduced. In addition, the input chute 56
If a cushioning material 57 having cushioning properties such as rubber or resin is attached to the upper surface of the container, the shock at the time of inputting the resource waste and the cracking of the bottle 58 can be suppressed.

The sieving / conveying apparatus according to the present invention is used for sieving small pieces and small foreign objects of bottles from recyclable refuse by a horizontal member 53 of a chain conveyor and a vertical member 54 cantilevered at one end. It is done by eye. That is, the resource waste supplied on the chain conveyor is transported to the unloading side on the side conveyor 53 of the chain conveyor, but the small pieces 59 smaller than the space (S ₁ ) between the side conveyors 53 fall down. At this time, if there is no vertical member 54, a thin but large area 60, for example,
Flattened cans and broken pieces such as the bottom of a bottle will fall downward when standing, even if the sides are longer than the horizontal distance (S ₁ ). However, in the present invention, the vertical member 54 is located below the horizontal member 53, and the interval (S ₂ ) is small. Therefore, the thin one 60 having a large area cannot be dropped. It is conveyed by the side 53 so as to slide on the upper side, and is drawn from the unloading section to the sorting conveyor 61 in the next step after drawing a parabola. Also, the small pieces 59 smaller than the squares (S ₁ × S ₂ ) are easily sieved and dropped by simply moving the chain conveyor, and easily pass between the horizontal sides 53 of the chain conveyor on the return side. It is not necessary to vibrate vigorously as in a conventional sieving device. The object 62 larger than the square (S ₁ × S ₂ ) is conveyed to the unloading side on the horizontal member 53 and discharged from the unloading section to the sorting conveyor 61 in the next process in a parabola.

In the sieving and conveying apparatus of the present invention, when viewed two-dimensionally, the horizontal lines 53 and the vertical lines 54 intersect, so that there appear to be many small squares (S ₁ × S ₂ ). However, since the horizontal members 53 and the vertical members 54 only form elongated slits, small pieces do not become clogged. In addition, since the horizontal member 53 and the vertical member 54 are in a relative motion relationship, even if vibration is not applied as in the conventional sieving device, the square (S ₁ ×
S ₂ ) The following items fall easily just by running the chain conveyor.

[0012] There are cases where many recyclable wastes have a bad shape or property. For example, wires, nails, bolts, ropes, pantyhose, and the like are liable to cause troubles such as biting into a machine, entanglement or winding and growing. In the sieving and conveying apparatus of the present invention, the support portion 55 of the vertical member 54 is provided only in the loading portion and is mounted in a cantilevered manner toward the unloading portion, so that small pieces or foreign substances are caught, entangled or wound. Growth can be suppressed.

[0013] The horizontal member 53 and the vertical member 54 used in the present invention.
It is preferable to use a round bar or pipe having a circular cross section so that small pieces can easily fall. The intervals (S ₁ , S ₂ ) between the horizontal members 53 and the vertical members 54 may be determined according to the small pieces to be sieved, and are not particularly limited. The vertical members 54 are arranged in multiple rows. However, since the vertical members 54 are not connected by a horizontal connecting member, foreign matter of any shape is not sandwiched. Furthermore, if the vertical member 54 that is cantilevered by the support portion 55 is supported by a bolt or the like so that the interval can be adjusted by the support portion 55, the size of the sieve can be adjusted.

The sieving / conveying apparatus of the present invention can substantially achieve the object without providing the vertical member 54 below the horizontal member 53. For example, when there is little mixing of broken pieces such as flat cans and the bottom of a bottle, there is no need to provide the vertical member 54 below the horizontal member 53.

[0015] Yokosan 5 of the sieving and conveying apparatus of the present invention
Since the small pieces 59 that have fallen from the squares of the 3 and the vertical members 54 fall downward from between the horizontal members 53 on the return side of the chain conveyor, whether a small-piece collection chute 63 or a cart type small box is provided below the chain conveyor. Alternatively, a basic pit may be opened in the lower portion, small pieces may be stacked in the basic pit, and when the small pits accumulate, they may be removed with a shovel or the like.
