A cam 52 that engages with the upper end of the valve stem 44 to press the valve stem is fixed to one end of the camshaft 51, and an operating lever 53 is fixed to the other end. A roller 54 is rotatably attached to the operating lever 50, and the roller engages with a cam track 13 provided on a circumference centered on the axis of the main shaft. Therefore, the operating lever 53 rotates due to the vertical displacement of the cam track, and the cam 52 rotates.
Thereby, the valve rod 44 is pressed to control opening and closing of the lower end of the nozzle pipe.

ク41内に流入できるようになつている。 The liquid tank 6 is formed by an annular main body 60, and is partitioned into a plurality of chambers 62 by a plurality of radial partition plates 61 spaced apart at equal intervals in the circumferential direction. In this embodiment, the number of chambers 62 is the same as the number of coating heads, but may be a multiple of that number. Inside of tank 41 of each coating head 4 and liquid tank 6
The bottom of each chamber 62 is connected by a pipe 65, respectively, so that the liquid in the chamber 62, that is, the fluorescent substance can flow into the tank 41.

dと離れて次の工程に送られていく。 When the glass tube held in the holder of the chain reaches position A, it begins to descend by the action of the cam track 12, and when it reaches position C, the lower end of the nozzle pipe 42 of the coating head 4 is moved as shown in FIG. 6 [C]. At the same time, the operation lever 53 is rotated by the action of the cam track 13, the valve stem 44 is pushed down, and the valve body 45 is separated from the lower end of the nozzle tube 42, causing the fireflies to enter the glass tube. Start applying the light body. When position D is reached, the valve stem 44 rises and the valve body 45 engages with the lower end of the nozzle, stopping coating and the coating head 4 begins to rise until reaching position F, as shown in FIG. ] Return to the state shown in
At this position, the holder is separated from sprocket d together with the chain and sent to the next process.
