In this example, in S5, the glass tubes that are not acceptable are arranged in order on a work table, cut into glass tubes of the required specifications with an alloy blade, and conveyed to a hopper in order by a vibrator for packing.
The dimensional requirements of the glass tube are as follows:
| model number | Outer diameter (mm) | Gram weight (g) |
| 3’ | 2.9-3.1 | 0.41---0.46 |
| 4’ | 3.55---3.703.65---3.85 | 0.64---0.73 |
| 5’ | 4.7----4.9 | 0.08---1.17 |
| 6’ | 5.65-5.855.7---5.9 | 1.47---1.65 |
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
