The gas injection unit may further include a driving unit protruding the gas injection nozzle for injecting the gas of a predetermined pressure, and reciprocating the gas injection unit so that the gas injection nozzle is inserted into the quartz tube.
The fluorescent lamp receiving unit is disposed in the carrying out direction of the fluorescent lamp and stops the fluorescent lamp carried out from the quartz tube and receives the stopper for aligning the position of the fluorescent lamp and the fluorescent lamp aligned by the stopper for transporting. It is provided with a roller. The fluorescent lamp receiving unit may further include a stopper driver for reciprocating the stopper in the longitudinal direction of the fluorescent lamp.
The fluorescent lamp receiver may further include a receiver roller driver for rotating the receiver roller and the stopper. The receiving roller is provided with a wing for passing the fluorescent lamp seated on the receiving roller to the fork to cross the fork provided in the loading section for loading the fluorescent lamp as the rotation.
According to another aspect of the present invention, a fluorescent lamp firing apparatus for firing a fluorescent lamp coated with a fluorescent material includes a transfer unit for transferring a quartz tube into which the fluorescent lamp is inserted, and a distance from one side of the transfer unit for firing the fluorescent lamp. And an unloading part for ejecting the fired fluorescent lamp by injecting a gas into a heating part and one hole of the quartz tube.
The unloading unit is a gas injection unit for inserting a gas injection nozzle reciprocating in the longitudinal direction of the quartz tube into one hole of the quartz tube and injecting a gas of a predetermined pressure to carry out the fluorescent lamp to the other hole of the quartz tube; And a stopper provided in the other hole direction to stop the fluorescent lamp carried out from the quartz tube and align the position of the fluorescent lamp.
In the fluorescent lamp unloading method according to another aspect of the present invention, when the quartz tube loaded with the fluorescent lamp is transported, inserting a gas injection nozzle into a hole on one side of the quartz tube by a predetermined distance, and of the quartz tube through the gas injection nozzle. Ejecting the fluorescent lamp to the other hole of the quartz tube by injecting gas in a longitudinal direction; and stopping and adjusting the position of the fluorescent lamp to be discharged with a stopper. The stopper may adjust the position of the fluorescent lamp by pushing the stopped fluorescent lamp in the longitudinal direction of the fluorescent lamp.
According to the present invention, it is possible to safely unload the fluorescent lamp. As a result, the yield of fluorescent lamps can be increased, thereby reducing raw material costs and extending the life of quartz tubes.
Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the unloading device and the fluorescent lamp firing apparatus according to the present invention.

When the quartz tube loaded with the fluorescent lamp is transferred to the unloading part, the gas injection nozzle of the gas injection part is inserted into one hole of the quartz tube (S110). The gas injection nozzle is inserted into the quartz tube at a distance that is not in contact with the fluorescent lamp.
The gas injection unit ejects the fluorescent lamp from the quartz tube by injecting a gas of a suitable pressure in which the fluorescent lamp may be seated to the fluorescent lamp receiving unit (S120). The gas injection part injects gas in the longitudinal direction of the quartz tube in the quartz tube so that only the fluorescent lamp is carried out to the other hole of the quartz tube without affecting the position of the quartz tube.
The fluorescent lamp carried out from the quartz tube is seated on the fluorescent lamp receiving unit, and the position of the fluorescent lamp is adjusted by the stopper (S130). The fluorescent lamp carried out by the gas pressure is stopped by the stopper and the shock is absorbed. The fluorescent lamp is mounted on the receiving roller. The stopper reciprocates in the longitudinal direction of the fluorescent lamp by the stopper driver. The stopper may adjust the position of the fluorescent lamp so that the fluorescent lamp is spaced apart from the stopper by a predetermined distance by pushing the fluorescent lamp in the longitudinal direction. The stopper is connected to the rotary shaft of the receiving roller and can rotate at the same speed as the receiving roller.
The fluorescent lamp is unloaded by the receiving roller (S140). By the plurality of receiving rollers provided with grooves corresponding to the diameters of the fluorescent lamps, the fluorescent lamps can be transferred to the next process or loading part. Alternatively, the receiving roller may be rotated such that the wing of the receiving roller and the fork of the loading unit intersect so that the fluorescent lamp seated on the receiving roller is passed to the fork of the loading unit. The fork has a certain tilt in the direction of the load, and the fluorescent lamp passed to the fork is slid to the load.
An embodiment of the present invention described above and illustrated in the drawings should not be construed as limiting the technical spirit of the present invention. The protection scope of the present invention is limited only by the matters described in the claims, and those skilled in the art can change and change the technical idea of the present invention in various forms. Therefore, such improvements and modifications will fall within the protection scope of the present invention, as will be apparent to those skilled in the art.
