Field of the Invention The present invention relates to a glass bottle sorting vibrating conveyor (hereinafter, also referred to as a vibrating conveyor) in an automatic glass bottle color sorting apparatus for reusing used glass bottles as resources, and more particularly to sorting glass bottles by color. In order to remove cracked bottles, ultra-small bottles of specified dimensions or less that reduce the sorting efficiency, and dust, etc. as pre-processing when sorting and removing glass bottles in the longitudinal direction and deliver them to the color sorting unit The present invention relates to a vibrating conveyor for sorting glass bottles in a glass bottle automatic color sorting apparatus.

[0002]

2. Description of the Related Art In recent years, there has been an increasing trend to collect used glass bottles and reuse them as resources from the viewpoint of saving resources and extending the life of waste disposal sites. Before reusing glass bottles as a resource, for example,
It is necessary to sort by the color of tea, green and other, glass bottle. Conventionally, sorting by color has been performed by human power. However, from the viewpoint of safety or hygiene, an automatic color sorting apparatus for performing the sorting by a machine has been developed.

FIG. 4 shows an automatic color sorting apparatus for glass bottles. That is, FIG.
FIG. 4 is a front view of the glass bottle automatic color sorter 1, FIG.
FIG. 1B is a plan view of the apparatus. The automatic color sorting apparatus 1 for glass bottles includes, from the upstream side, a vibrating conveyor 2 serving also as a primary sorting and supplying apparatus for glass bottles,
, A sorting conveyor 3 for aligning the glass bottles that have been primarily sorted and delivered, a relay conveyor 4 for adjusting the gap between the glass bottles, a transport conveyor 5, and the color sorting provided in the middle of the transport conveyor 5. A color identification device 6 as a unit, a sorting device 7 for sorting each color based on the identification of the color identification device 6, and a discharge conveyor 8 for discharging damaged products or extremely small bottles whose diameter is equal to or less than a specified size.

An alignment conveyor 3 which is continuous with the vibrating conveyor 2 has a V-shaped cross section, receives a glass bottle which is primarily sorted by the vibrating conveyor, and falls down, that is, a state where the glass bottle is laid down sideways, that is, the axis of the glass bottle. The transfer is performed one by one with the direction and transfer direction aligned. The glass bottles conveyed one by one are aligned on the relay conveyor 4 at predetermined intervals.

The color discriminating device 6 illuminates the glass bottle being conveyed by the conveyor 5 with an illuminating device provided on the side of the conveyor, detects the transmitted light of the glass bottle, and detects the color of the glass bottle. Based on this detection, the sorting device 7 sorts the glass bottles into, for example, glass bottles of, for example, brown, transparent, and mixed colors. The space from the alignment conveyor 3 to the sorting device 7 is covered with a box-shaped cover 9 from the viewpoint of safety or soundproofing.

In the glass bottle automatic color sorting apparatus 1 as described above, the glass bottles supplied to the vibrating conveyor 2 for sorting the glass bottles have various shapes, dimensions and the like. When sorting is performed, the processing capacity per unit time does not increase, and the processing efficiency is poor. That is, in order to quickly perform accurate color selection,
It is necessary to supply glass bottles one by one to the color discriminator at equal intervals. However, when performing color selection processing with the size and shape of the glass bottles mixed, it is necessary to slow down the supply speed of the glass bottles. This leads to a reduction in processing efficiency.

Further, when the broken glass bottles are mixed, the broken glass bottles are overlapped with each other, which may cause a plurality of lights to be received in the transmitted light detection, resulting in erroneous color discrimination or processing as unrecognizable. Therefore, as a primary sorting of glass bottles to be processed, a grizzly river is provided on a vibrating conveyor to remove broken bottles, extremely small bottles, and the like, and the damaged product, very small bottles, and the like are dropped and extracted below the vibrating conveyor.

[0008]

FIGS. 5 to 7 are external perspective views of a conventional grizzly river provided on the vibrating conveyor. As mentioned above, the glass bottles supplied to the vibrating conveyor have various diameters and shapes,
The selection has a very difficult problem.

First, when the upper surface of the grizzly bar 10 is flat as shown in FIG. 5 and the gap between the respective grizzly bars 9 is narrow on the upstream side and wide on the downstream side to form a trapezoidal opening, When a bottle with a diameter close to is transferred, a clogging situation may be exhibited. Therefore, in order to eliminate the clogging state and improve the sorting effect, the grizzly river 10 is divided into a plurality of stages in the direction of transferring the glass bottle as shown in FIGS. If a plurality of steps are provided for each step, and a large gap (opening) is formed between each of the grizzly bars, the clogging phenomenon between the above-mentioned grizzly bars is reduced, but clogging may occur when the operation of the apparatus is stopped.

Further, since the glass bottles fall toward the bottom of the alignment conveyor 3 having a V-shaped cross section at the transfer portion (exit chute), the glass bottles are concentrated on this portion, and There is a disadvantage that the glass bottles are not smoothly delivered because they are stacked in a pyramid shape or are transported with the bottles facing upward.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problem, and it is an object of the present invention to prevent a glass bottle from being clogged in a grizzly river and to quickly sort a broken bottle, a very small bottle having a specified diameter or less, and dust. It is an object of the present invention to provide a glass bottle sorting vibrating conveyor in a glass bottle color sorting apparatus that can be used. In addition, the glass bottles can be sequentially aligned in the longitudinal direction, and the delivery to the next process can be smoothly performed.Therefore, the color sorting of the glass bottles can be performed accurately and quickly. It is an object of the present invention to provide a vibrating conveyor for sorting glass bottles that does not break.
