[0007]
[Action]
A glass tube to be cut to a predetermined length is judged as a non-defective product or a defective product in an inspection section before cutting. When the glass tube is a non-defective product, the guide member is at a position that does not interfere with the dropping of the glass tube, and the cut glass tube is dropped onto the non-defective product conveyor and conveyed to the next process. If the glass tube is defective, the glass tube is received and dropped to flow to the defective product disposal section, and the direction position is changed. Thus, since the guide member is only rotated according to whether the glass tube is good or bad, it is possible to perform stable and accurate automatic selection from the low speed range to the high speed range of the glass tube manufacturing speed.

Reference numeral 10 is a non-defective product conveyor, 11 is a defective product disposal section, 12 is a guide member, G is a glass tube, and G 'is a glass main tube.
[0011]
The non-defective product conveyer 10 receives the glass tube G cut from the glass main tube G ′ by the cutter 13 and conveys it to the next process. Two endless belts that run in a substantially horizontal direction are connected to the glass main tube G ′. Are arranged in a direction perpendicular to the tube drawing direction.
[0012]
The defective product discarding unit 11 is installed on the opposite side of the non-defective product conveyor 10, and for example, a crusher or the like is disposed so that the defective glass tube G is crushed and collected by the cullet conveyor.
[0013]
The guide member 12 is for flowing and discharging the defective glass tube G to the defective product disposal unit 11, and the guide surface is disposed between the non-defective product conveyor 10 and the defective product disposal unit 11 on the defective product disposal unit 11 side. It is installed in a tilted state. The guide member 12 is connected to a rotary shaft 14 'of a rotary drive source 14 such as a servo motor, and is rotatable about the rotary shaft 14'. As shown by a solid line and a one-dot chain line in FIG. In the case of the glass tube G, the glass tube G is in a position where it does not interfere with the drop, and in the case of the defective glass tube G, the glass tube that is dropped is received and rotated to change the direction position so as to flow to the defective product disposal unit 11. is there.
[0014]
