Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sorting apparatus for sorting dust mixed with particulate matter and linear matter into granular matter and linear matter. This sorting device can be used to separate a linear object from a mixture of granular materials (glass, plastic particles, etc.) and linear objects (wire harness, etc.) such as automobile shredder dust.

[0002]

2. Description of the Related Art Conventionally, to separate a long linear object 6 (a wire harness or the like) and particles 8 (glass, plastic particles or the like) from a mixture, a long linear object is shown in FIG. Comb 2 in which rod-like materials like this are arranged in parallel at regular intervals
1 or a mesh-like sieve 22 as shown in FIG. 11 was used.

[0003]

However, in the case of a rod-shaped comb, the amount of long linear objects collected is small, and only about 9% of the total amount of base material (shredder dust) can be sampled. This is because the comb bars are arranged in parallel with a space,
This is because if a linear object such as a wire harness becomes parallel to the comb rod, it will pass between the rods. Further, when using a sieve, the collection rate of the wire harness is as high as 50% or more, but the wire harness or the like is entangled with the sieve, and even if the sieve is inverted, it cannot be removed unless it is strongly hit. Therefore, continuous processing cannot be performed. An object of the present invention is to provide a sorting device that has a large collection rate of long linear objects and has little entanglement.

[0004]

The device of the present invention for achieving the above object is as follows. (1) A dust sorting apparatus in which particulate matter and linear matter are mixed, wherein a feeder for transporting dust and a plate member arranged on the outlet side of the feeder are combined in a lattice shape to form a radius in the lattice height direction. A sorting device having a lattice comb assembled in a cylindrical shape in the direction, and a shooter having one end inserted inside the lattice comb. (2) A dust sorting device for mixing particulate matter and linear matter, comprising a feeder for transporting the dust, and a plurality of comb-like units that are arranged on the outlet side of the feeder and are formed by combining plate members in a grid pattern. A sorting device having a lattice comb that is connected and assembled in an endless strip shape, and a shooter having one end inserted inside the lattice comb. (3) The sorting device according to (1) or (2), in which an end surface of the plate member of the lattice comb that is in contact with dust is inclined from a plane orthogonal to the lattice height.

[0005]

In the device of the above (1), since the combs have a lattice shape,
Since the linear object is caught on one of the plate members orthogonal to each other, it is difficult for the linear object to pass through between the grid-like plate members, and the collection rate becomes larger than that of the sieve. Further, since the lattice has a large height equal to the width of the plate member, even if the linear object is bent at the upper end of one plate member and extends downward on both sides of the plate member, the lower end of the line member reaches the lower end of the plate member. It is difficult for the wire member to reach the lower end of the wire member, and the lower end of the wire member is not easily bent and entangled with the wire member. The unentangled filaments are removed from the lattice when the cylindrical comb is inverted. Granules easily pass through the comb lattice, are received on the shooter and are removed by the shooter. The device of the above (2) can also obtain the operation similar to that of the device of the above (1).
In the device of the above (3), since the end faces of the comb-like plate-like object are inclined, when the particulate matter is placed on the end face, it slides down by its own weight along the inclined surface and passes through the lattice. It easily falls on the shooter. For this reason, unlike the case where there is no inclination, it is less likely to be rejected to the linear object receiving side together with the linear object while remaining stable on the end surface of the plate object. Will no longer contain a large amount of particulate matter. Therefore, the sorting efficiency is improved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A preferred embodiment of the present invention will be described below with reference to the drawings. 1 to 3 show a common configuration applicable to any embodiment of the present invention, FIGS. 4 and 5 show a first embodiment of the present invention, and FIG. 6 shows a second embodiment of the present invention. An example is shown. The same components are given the same reference numerals throughout the embodiments. First, a configuration common to any of the embodiments of the present invention will be described with reference to FIGS. 1 to 3, 4 and 5. As shown in FIG. 4, the sorting apparatus according to the embodiment of the present invention transfers dust 13 (for example, shredder dust of an abandoned automobile) in which long linear objects 6, for example, wire harness and granular material 8 glass, and plastic particles are mixed. Feeder 5, a lattice comb 3 arranged on the outlet side of the feeder 5 and assembled by combining the plate members 1 and 2 in a lattice shape, and one end of the lattice comb 3 is inserted inside the lattice comb 3 to form a lattice comb. A shooter 10 which receives and takes out the granular material 8 falling from 3;
Consists of. The sorting device further includes a granular material tray 9 for receiving the granular material 8 from the shooter 10 and a linear material tray 7 for receiving the linear material 6 from the lattice comb 3. The grid comb 3 is inverted by the drive shaft 4.

As shown in FIG. 1, the lattice comb 3 is formed by combining the plate-like members 1 and 2 in a lattice shape with the width direction of the plate members in the lattice height direction. It was confirmed by tests that the grid shape dimension is desirably set as follows in order to improve the selection efficiency. a = X ± X / 2 b = a to 10a c = a / 10 to a / 5 where X: maximum particle passage hole diameter (maximum diameter of maximum granular material) a: in-lattice dimension b: lattice height c: Thickness of the plate-shaped material of the lattice Since X = 12 mm in shredder dust of an abandoned automobile, a = 6 to 18 mm = 13 mm, b = 10 to 100 m
m = 50 mm and c = 0.5 to 2 mm = 2 mm.

The end faces of the plate members 1 and 2 of the lattice comb 3 which are in contact with the dust 13 are inclined from the plane orthogonal to the lattice height. 2 shows a case where only one plate member 2 of the plate members 1 and 2 orthogonal to each other is inclined, and FIG. 3 shows both plate members 1 and 2 of the plate members 1 and 2 orthogonal to each other. 2 shows the case where a slope is added. Such a slope is easily provided by chamfering.

Next, the structure peculiar to each embodiment of the present invention will be described. In the first embodiment of the present invention, as shown in FIGS. 4 and 5, the lattice comb 3 is assembled into a hollow cylindrical shape with its axis being horizontal, and the lattice height direction is the radial direction of the cylindrical shape. Is directed to. The feeder 5 supplies the dust 13 to the upper end of the cylindrical lattice comb 3. Also, the shooter 10
Is inserted into the inner side of the cylindrical lattice comb 3, and the other end is out of the cylindrical lattice comb 3. The shooter 10 is inclined so that the granular material 8 slides down by its own weight. The drive shaft 4 rotates the lattice comb 3 around the axis.

In the second embodiment of the present invention, as shown in FIG. 6, the lattice comb 3 is formed by connecting the single lattices 11 in an endless belt shape. A gap 12 is provided inside each of the lattice elements 11 adjacent to each other so that dust is not caught or even if it is caught, it can be removed. The chain 14 is connected to the endless belt-shaped lattice comb 3,
By meshing 4 with two sprockets 15 and driving one of the sprockets 15 with the drive shaft 4, the lattice comb 3 is driven in one direction. The feeder 5 includes, for example, a vibrating electromagnetic feeder 5, and supplies the dust 13 to the upper surface of the upper end horizontal portion of the endless belt-shaped lattice comb 3. The shooter 10 extends obliquely from the inside to the outside of the endless band-shaped lattice comb 3.

Next, the operation will be described. The operation common to all the embodiments will be described. The dust 13 is separated into the granular material 8 and the linear material 6 by the lattice comb 3, and the granular material 8
Are collected in the granular material tray 9 and the linear objects 6 in the linear object tray 7. Unlike the rod-shaped combs, even if the linear object 6 is parallel to the plate member 1 on one side, the lattice comb 3 is prevented from passing by the plate member 2 orthogonal to the plate member 1. Increases more than conventional sieves. In the case of a sieve, linear objects are entangled in the net, but in the lattice comb 3 made of a plate member having a large lattice height, the linear member 6 is entangled in the plate members 1 and 2 as shown in FIG. It is not possible to do so, and dust is not entangled in combs. Then, only the granular material 8 passes through the spaces between the lattices, falls on the shooter 10, is carried by the shooter 10 to the outside of the comb, and is collected. Further, since the end faces of the plate members 1 and 2 are inclined, the granular material 8 cannot stay on the end faces of the plate members, but passes through the lattices and falls on the shooter 10. Therefore, the sorting efficiency is increased. 7, FIG. 8, and FIG.
The actual selection result by the device of the present invention is shown. 7 shows the dust 13 in which the granular material 8 and the linear material 6 are mixed, FIG. 8 mainly contains the linear material 6 collected in the linear material receiving tray 7, and FIG. The thing which mainly contains the granulated material 8 shown is shown. 47 items collected in the linear object tray 7
% (Weight ratio) or more of linear substances are contained. Moreover, although the thing of FIG. 9 contains a short linear object, it does not contain a long linear object. As can be seen from the figure, the separation efficiency is high in the embodiment of the present invention.

The operation peculiar to each embodiment will be described.
In the first embodiment, since the lattice comb 3 has a cylindrical shape, the lattice axis is inclined at the time of separation, which facilitates the passage of particulate matter and simplifies the apparatus. For the second embodiment,
Since the lattice comb 3 has an endless belt shape, the device is large, but the dust remains on the lattice comb 3 for a long time, and the separation performance is great.

[0013]

According to the sorting apparatus of the first aspect, since the plate members are combined in a lattice shape and are assembled into a cylindrical shape to form a lattice comb, it is difficult for the linear member to pass through the lattice, and granular materials are formed. The efficiency of separation from the linear objects can be improved, and since the height of the grid (width of the plate member) is high, entanglement of the linear objects with the grid can be suppressed. According to the sorting apparatus of the second aspect, an effect similar to that of the sorting apparatus of the first aspect can be obtained. According to the sorting apparatus of claim 3, since the end surface of the plate member is inclined, it becomes easier for the particulate matter to pass through the lattice and drop without staying on the lattice, thereby increasing the separation efficiency between the particulate matter and the linear matter. Can be improved.
