Description

[Detailed description of the invention]

0001

[Industrial Application Field] The present invention relates to a method for sorting and collecting bottles in non-burnable garbage by color, and more specifically, the present invention relates to a method for sorting and collecting bottles in non-burnable garbage by color, and more specifically, to collect glass bottles from garbage mainly consisting of glass bottles sorted and separated by a glass bottle sorter or the like. After classifying by thickness,
It relates to a method of automatically sorting and collecting according to color.

0002

[Prior Art] Recently, in order to cope with the increase in municipal waste,
Attempts are being made to recover valuable materials such as bottles from non-flammable materials and bulky garbage discharged from ordinary households. When collecting glass bottles among non-combustible materials, the garbage to be treated from general households is sorted mechanically or manually into combustibles, plastics, metals, glass bottles, etc., without being crushed. Afterwards, valuables are collected and sent to respective processing facilities. Among the valuable materials, glass bottles are sorted by sorting machines, collected manually by color, and then recycled.

0003

[Problems to be Solved by the Invention] Garbage brought into a treatment plant often contains a large volume of paper, cloth, and especially plastic. Furthermore, in the case of glass bottles, it is necessary to sort them by color in consideration of later processing, and if manual sorting is to be performed for this purpose, a large amount of manpower is required. Furthermore, during the collection stage, injection needles and the like get mixed in, which poses many safety problems. Therefore, systems have been developed that automatically mechanically sort bottles. This system separates waste containing valuables into at least plastic-based material and the remainder containing valuables such as bottles, without actually crushing the waste, and separates the waste containing valuables such as bottles from the remainder. Bottles sorting machine (e.g. incline sorting machine)
This is a method of sorting by. However, even in this system, although the sorting machine that sorts bottles can sort garbage into bottles that mainly consist of bottles, it is not possible to sort glass bottles by color. Separating and sorting must be done manually and requires a large number of people.

[0004] In view of this conventional situation, the present invention attempts to propose a method for mechanically collecting glass bottles according to their thickness and color from waste mainly consisting of glass bottles sorted by an automatic sorter or the like. It is something to do.

[0005]

[Means for Solving the Problems] This invention supplies waste mainly consisting of glass bottles that have been sorted and separated by a glass bottle sorter or the like to a classification device, and sorts the glass bottles according to their thickness. The glass bottles are fed to a bottle conveyance line classified by thickness by an alignment feeding device, the color of the bottle is detected by a color sensor attached to the conveyance line, and the color of the bottle is detected by a color dispensing device attached to the same line. The gist of this is a method of discharging and collecting materials to a color-based transport line that is arranged separately from a thickness-based transport line.

[0006]

[Operation] Garbage mainly consisting of glass bottles sorted by an incline sorter or the like is supplied to a classification device. The glass bottles that have been sorted by size by the classifier are continuously conveyed to the bottle conveyance line by size via the alignment feeder, and during the conveyance process, the color of the glass bottles is detected by a color sensor. Glass bottles are dispensed by color and collected by color on a conveyance line. As the classification device, for example, a vibrating sieve with sieve mesh divided into a plurality of sections according to the thickness of the glass bottle can be used. As the color-based dispensing device, for example, a pusher type device can be used.

[0007] This method allows the glass bottles to be continuously sorted by color with almost no need for manpower, so that the glass bottles are sorted safely and efficiently, and the sorting accuracy is also high.

[0008]

[Example] Fig. 1 is a schematic perspective view showing an example of equipment for carrying out the method of the present invention, in which 1 is a classifying vibrating sieve, 2 is a quantitative feeding device, 3 is an alignment feeding device, and 4 is a conveyor for bottles classified by size. A conveyor, 5 a color sensor, 6 a color dispensing device, 7 a color conveyor, 8 a crusher, 9 a bunker, 10 a residue conveyor, and 11 a control system for the color dispensing device 6, respectively. .

The classification vibrating sieve 1 has a frame 1-2 whose four corners are supported by supports 1-1, and has sieve mesh groups 1A to 1F divided into a plurality of groups according to the thickness of the glass bottle, and is powered by a power source. It has a structure that applies vibrations. For each phloem group, for example, 1A is 25
mm or less, 1B is 45 mm or less, 1C is 55 mm or less,
1D is 65mm or less, 1E is 70mm or less, 1F is 11
It has a sieve size of 0 mm or less.

[0010] The quantitative supply device 2 and the alignment feed device 3 are as follows:
This is a device that quantitatively arranges the glass bottles of each size that have fallen from the classification vibrating sieve 1 and sends them to the bottle transport conveyor 4 for each size, and both devices are structurally composed of a chute and a normal inversion device. Can be done. That is, a normal inverted device having a wide chute portion for receiving and feeding glass bottles under each sieve mesh group and a narrow chute portion for arranging glass bottles one by one at the terminal end is used as the sorting device 1 and for conveying bottles by size. It is placed between the conveyor 4 and the conveyor 4. The width of each size-specific bottle transport conveyor 4 is determined according to the thickness of the glass bottle. In addition, as a glass bottle alignment device, upright,
It is also possible to adopt a type in which all the containers supplied in one row are arranged in an upright state and fed into the chute regardless of whether they are inverted.

The color sensors 5 detect the colors of the glass bottles moving on the bottle conveyor 4 according to thickness, and are arranged at appropriate intervals along the conveyor 4 according to each thickness. The colors of glass bottles are transparent, brown, blue, green, and black, but here transparent is detected as white. For example, the arrangement order from the upstream side is white sensor 5-1, brown sensor 5-2, blue sensor 5-3, green sensor 5-4, and black sensor 5-5.
Place them in this order. Note that as this color-specific sensor, for example, a device used for checking the color discrimination of wire harnesses, checking the arrangement of colored pencils, etc. can be adopted.

The color-based dispensing device 6 uses a pusher type device using a cylinder, for example, and a color-based conveyor 7.
Install it so that it comes out in a direction perpendicular to the direction. This dispensing device 6 is also installed in a pair with a sensor 5 for each color on the conveyance line 4 for each thickness, and dispensing for each color is performed via the control system 11 based on the detection signals of the sensors 5-1 to 5-5 for each color. Device 6
-1 to 6-5 are configured to operate automatically.

The color-separated conveyor 7 has a color-separated delivery device 6.
This line is arranged perpendicularly to the size-specific bottle transport conveyor 4 and supplies the glass bottles discharged from the color-categorized dispensing device 6 to each crusher 8 at the terminal end.

[0014] In the equipment configured as described above, the waste mainly consisting of glass bottles, which has been sorted in the preceding treatment system, is supplied to the classification vibrating sieve 1, where it is classified according to the thickness of the glass bottles. In other words, bottles with a thickness (maximum diameter) of 25 mm or less are classified into sieve group 1A, and bottles with a thickness of 45 mm or less are classified into sieve group 1.
From B, those with a thickness of 55 mm or less are from phloem group 1C,
Those with a thickness of 65 mm or less are from phloem group 1D, and the thickness is 7.
Those with a thickness of 0 mm or less are from phloem group 1E, and the thickness is 110 mm.
The following items fall from the sieve group 1F. The glass bottles that have fallen from each sieve are transferred to a size-specific bottle transport conveyor 4 via a quantitative supply device 2 and an alignment feed device 3.
Books are arranged and transported one by one. This conveyor conveyor for bottles by thickness 4
The glass bottles supplied to each color sensor 5-1 to 5
For example, a white glass bottle is detected by the white sensor 5-1, and the paired dispensing device 6-1
is pushed out onto the color-separated conveyor 7. The glass bottles sorted according to color in this manner are supplied to a crusher 8 on a color-separated conveyor 7, and then stored in a bunker 9. On the other hand, the residue mixed with the glass bottles and conveyed is discharged by a residue conveyor 10 installed at the end of the bottle conveyor 4 for each size.

[0015]

[Effects of the Invention] As explained above, according to the method of the present invention, glass bottles can be automatically sorted and collected by thickness and color from waste mainly composed of glass bottles, so that the accuracy of glass bottle sorting can be improved. Not only is it high;
Compared to the previous manual sorting method, glass bottles can be sorted more efficiently and safely, making it extremely practical as a glass bottle collection system and having great effects on resource recycling through the reuse of glass bottles.
