Abstract

PURPOSE:To eliminate the discrimination mistake of a waste container and to enable sorting of high accuracy by providing a waste container size classifying means and a waste container arranging means and providing a detector detecting the color of the container and a distribution means distributing the container on the basis of the signal of the detector to the arranging means. CONSTITUTION:The waste containers A supplied from a supply passage 4 are classified by sizes during the movement on a vibration screen 1 while the surfaces thereof are washed and discharged to respective arranging conveyors 2, 3. The discharged waste containers A are respectively arranged in the same direction to be moved through arranging passages 16 and the colors of the containers A are detected by color detectors 18 during movement. The respective containers A are distributed by colors such as white, brown or the like on the basis of the detection results by a distribution plate 19 to perform sorting corresponding to a purpose of reutilization. Since the arranged containers A are distributed by colors according to use kinds, the waste containers A can be continuously and efficiently sorted.

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 waste containers such as glass bottles and plastic bottles according to the purpose of reuse.

[0002]

2. Description of the Related Art Many of the used waste containers such as glass bottles and plastic bottles are required to be reused. To ensure this reuse, each container is classified according to size and type of use. It is necessary to sort accurately.

Conventionally, such a waste container is sorted by arranging a large number of workers along a conveyor for transporting the containers and taking out various containers from the conveyor by the judgment and manual work of each worker. ing.

[0004]

However, as described above, in the sorting method manually performed by the operator, the work efficiency is low,
There is a drawback that costs such as personnel expenses also increase. Further, since the selection of the containers depends on the judgment of each operator, there is a drawback that the selection tends to vary and the selection accuracy is poor.

Therefore, an object of the present invention is to solve the above-mentioned problems and to provide a sorting apparatus capable of mechanically sorting waste containers with high accuracy without manual labor of a person.

[0006]

In order to solve the above problems, the sorting apparatus of the present invention has size sorting means for sorting the waste containers by size, and aligning means for aligning the sorted containers. The arrangement means is provided with a detector for detecting the color of the aligned containers and a distribution mechanism for distributing the containers based on the signal from the detector.

[0007]

In the above structure, the waste sorting containers are sorted by size by the size sorting means, the colors of the sorted sorting containers are detected by the aligning means, and the sorting containers are sorted according to the type of use based on the detected colors.

[0008]

Embodiments of the present invention will be described below with reference to the accompanying drawings. As shown in FIG. 1, the sorting apparatus of the embodiment is
A vibrating screen 1 for separating the size of the waste container and the vibrating screen 1
A plurality of alignment conveyors 2 and 3 connected to the outlets 5 and 6, respectively, and a supply passage 4 for supplying a waste container is connected to the upper end of the vibrating screen 1 on the tip side.

As shown in FIGS. 2 and 3, the vibrating screen 1 includes two screen plates 7 and 8 having different mesh sizes which are vertically stacked and the lower screen plate 8 is provided with springs 9 and 9. 1 which is elastically supported by and is attached to the lower sieve plate 8
By vibrating 0, the sieve plates 7 and 8 vibrate in the vertical and front-back directions.

A washing water supply device 11 is provided above the sieve plates 7 and 8 to sprinkle the washing water in a shower shape.
Below the vibrating screen 1, a hopper 12 for receiving dirt and dust washed from the waste container A is provided.

In the vibrating screen 1 described above, when the waste container A introduced from the supply passage 4 moves on the screen plates 7 and 8 with vibration, each container is caused by the size of the mesh of the screen plates 7 and 8. A is sorted by size, and at the same time, the surface of the container A is washed with washing water and discharged from the outlets 5 and 6.

The alignment conveyors 2 and 3 connected to the outlets 5 and 6 of the vibrating screen 1 are tapered passages whose width becomes narrower toward the front side of the conveyor base 13 whose lower surface is supported by springs 14 and 14. 15 is provided, on the rear side of the conveyor base 13,
It is configured by providing alignment passages 16 having parallel widths. Further, a vibrator 17 is attached to the conveyor base 13,
When the conveyor base 13 is vibrated by the vibrator 17,
The containers A are sequentially aligned by the guide of the tapered passage 15,
The alignment passage 16 is moved while aligned in the same direction.

A color detector 18 for detecting the color of the aligned containers A is provided in the middle of the alignment passage 16, and a plurality of containers A moving in alignment are collected at the exit of the alignment passage 16. A distribution plate 19 for distributing the passages 20 and 21 is provided. The distribution plate 19 is rotated left and right by a drive unit (not shown), and the drive unit is controlled so as to change the rotation direction of the distribution plate 19 based on a signal from the color detector 18.

As the color detector 18, various detectors such as a detector using a transmission type or a reflection type, or a detector utilizing spectral analysis may be used as long as it has a function of identifying the color of the surface of the container A. You can

The sorting apparatus of the embodiment has the structure as described above, and the waste container A supplied from the supply passage 4 is the vibrating sieve 1.
While being moved, it is sorted according to each size and the surface is washed and discharged to each of the alignment conveyors 2 and 3. The waste containers A discharged to the alignment conveyors 2 and 3 are aligned in the same direction and move in the alignment passage 16, and the color of the container A is detected by the color detector 18 while moving. Next, based on the result detected by the color detector 18,
The distribution plate 19 distributes each container A to a color such as white or brown, and performs sorting according to the purpose of reuse.

In the above example, the vibrating screen 1 is formed by stacking the screen plates 7 and 8 in two stages, but the screen may be formed in three or more stages.

[0017]

As described above, according to the present invention, the size sorting means and the arranging means of the waste containers are provided, and the aligned containers are sorted according to the type of use according to the color, so that the waste containers can be continuously and efficiently selected. be able to.

Further, since the type of the waste container is mechanically identified by the color detector, there is no mistake in the identification of the container, and the sorting can be performed with high accuracy.
