Claims (9)

In a cullet removing device that sucks and removes cullet generated when scribing or breaking brittle material,
A pair of gas passages for respectively leading up and down airflow;
A gas injection part provided at an upper part of at least one of the gas passage parts, one end opening to the gas passage part, and the other end connected to a gas injection mechanism for injecting gas;
A straight pipe part having a constant cross-sectional shape, connected between the lower ends of the pair of gas passage parts,
A suction opening that opens at an upper end of the pair of gas passages and is connected to a suction mechanism that sucks the gas;
A cullet removing device, wherein a cullet suction port opened below the straight pipe portion is formed.   2. The cullet removing apparatus according to claim 1, wherein the straight pipe portion is disposed so that a central axis thereof is substantially parallel to a surface of a brittle material supported below the cullet suction port. The gas injection part is provided on each upper part of the gas passage part,
One end of the gas injection unit is open to the gas passage unit, and the other end is connected to the gas injection mechanism via an injection selection switching unit that selects gas to be injected from one of the gas injection units. And
A flow path switching unit that switches so that either one of the upper ends of the pair of gas passages is connected to the suction opening;
According to the relative movement direction of the brittle material, the upper end portion of the gas passage portion and the suction opening portion in which the gas is injected from one of the pair of gas injection portions and the other gas injection portion is provided The cullet removing apparatus according to claim 1 or 2, wherein the flow path switching unit is switched so that the two are connected to each other.   Gas is injected from one of the pair of gas injection portions provided on the direction side where the brittle material approaches, and the upper end portion of the gas passage portion and the suction opening are connected on the direction side where the brittle material leaves. The cullet removing apparatus according to claim 3, wherein the flow path switching unit is switched.   The cullet removing device according to any one of claims 1 to 4, wherein a rectifying member that rectifies the flow of the passing gas is disposed below the pair of gas injection units.   6. The cullet removing apparatus according to claim 5, wherein a plurality of the rectifying members are arranged in a direction substantially orthogonal to a relative moving direction of the brittle material.   The cullet removing device according to claim 6, wherein the plurality of rectifying members are arranged so that the size thereof decreases as the distance from the central portion increases.   The cullet removing device according to any one of claims 1 to 7, wherein a cross-sectional area of the pair of gas passage portions gradually decreases toward the lower side. In a cullet removing device that sucks and removes cullet generated when scribing or breaking brittle material,
A pair of gas passage portions for respectively leading up and down airflow;
A gas injection part provided at the upper part of the gas passage part for guiding the descending airflow, one end opened to the gas passage part, and the other end connected to a gas injection mechanism for injecting gas;
A straight pipe part having a constant cross-sectional shape, connected between the lower ends of the pair of gas passage parts,
A suction opening that opens at the upper end of the gas passage that guides the rising airflow and is connected to a suction mechanism that sucks the gas;
Have
A cullet removing device, wherein a cullet suction port opened below the straight pipe portion is formed.
