本発明は陰極線管の製造工程において用いるネック部洗
浄装置に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a neck cleaning device used in the manufacturing process of cathode ray tubes.

ー抜きパイプ７が設けられている。A conventional neck cleaning device for a cathode ray tube has a structure as shown in FIG. That is, the cleaning water 2 in the cleaning tank I
Nitrogen is constantly supplied through a supply port 3 provided at the bottom of the cleaning tank 1, and an air bleed pipe 7 is provided to exhaust the air inside the cathode ray tube through the collection tank 4 through which the nitrogen constantly flows out of the cleaning tank 1. It is provided.

いう欠点があった。However, in such a dip-type neck cleaning device, although the cleaning water outside the neck 6 overflows, the cleaning water inside the neck 6 is not replaced. Therefore, when the cathode ray tube is pulled up, the stagnant foreign matter inside the neck 6 tends to adhere to the inner wall of the neck 6 again.
本発明の目的は、ネック内壁も良好な洗浄が行なえる陰
極線管のネック部洗浄装置を提供することにある。SUMMARY OF THE INVENTION An object of the present invention is to provide a neck cleaning device for a cathode ray tube that can effectively clean the inner wall of the neck.

パイプを設けたことを特徴とする。The present invention provides a cleaning tank for overflowing cleaning water, and an air bleed pipe provided in the cleaning tank for removing air from the cathode ray tube when the neck of the cathode ray tube is dipped into the cleaning water. The pipe neck cleaning device is characterized in that a drainage pipe is provided outside the air bleed pipe.

と同じ捕造よシなる。An embodiment of the present invention will be described below with reference to FIG. Washing water 2 in the washing tank I is constantly supplied through a supply port 3 provided at the bottom of the washing tank I, overflows the washing tank I, passes through a recovery tank 4, and is discharged through a drain port 5. An air bleed pipe 7 is provided in the cleaning tank 1 to evacuate air from inside the cathode ray tube when the neck 6 of the cathode ray tube is dipped in the cleaning water 2. The above is the same trap as in Figure 1.
本発明は、エアー抜きパイプ７の外側には排水パイプ８

In a cathode ray tube neck cleaning device equipped with a pipe, a drain pipe is provided outside the air bleed pipe, so when the neck is dipped in cleaning water, the cleaning water in the neck overflows into the drain pipe. The water is constantly replaced with fresh water, no foreign matter remains in the neck, and the inner wall of the neck is cleaned extremely well.
