より成ることを特徴とする。 The method of removing the explosion-proof band of the cathode ray tube according to the present invention comprises a step of peeling off an end portion of the explosion-proof band wound around the cathode ray tube from the cathode ray tube, and a plurality of rod-like claws adjacent to each other. A step of pinching, a step of rotating the claw around an axis common to the claw and winding the explosion-proof band, and a step of rotating the claw around the common axis and simultaneously moving the cathode ray tube to the claw Rotating around the axis passing through the center of the CRT panel surface and the neck of the CRT in the same direction as the rotation direction;
It is characterized by comprising.

また、本発明のブラウン管の防爆用バンドの取外し方法においては、上記防爆用バンドがガイドによって支持されながら巻き取られることを特徴とする。   In the method for removing an explosion-proof band for a cathode ray tube according to the present invention, the explosion-proof band is wound while being supported by a guide.

本発明のブラウン管の防爆用バンドの取外し方法によれば、防爆用バンドをブラウン管から容易に取り外し、小さな直径の塊りとすることができ、簡単に移動処理できるようになる。   According to the method of removing the explosion-proof band of the cathode ray tube of the present invention, the explosion-proof band can be easily detached from the cathode ray tube to form a lump having a small diameter and can be easily moved.

以下図面によって本発明の実施例を説明する。   Embodiments of the present invention will be described below with reference to the drawings.

本発明においては図１に示すようにブラウン管１の周りに巻かれた防爆用バンド５をカッター等で切断し、防爆用バンド５の切断端をブラウン管１の周りから引きはがし、この引きはがした端部６を、図２に示すように互いに隣接せしめた複数の例えば４本の、直径例えば１６ｍｍの棒状の爪７で表、裏から挟み、図３に示すようにこの爪７を一体にこれら爪に共通の縦軸を中心として例えば時計方向に回動してバンド５を巻き取り、同時にブラウン管１も上記パネル２の表面の中心と上記ネック部４を通る軸線を中心として同一の方向例えば時計方向に回動せしめる。この際巻き取られるバンド５はＬ型ガイド８によってガイドしこの結果、巻き取られたバンド５は図４に示すように例えば直径１５０ｍｍの小さな塊り９のようになるからその処理及び搬送が極めて容易となる。   In the present invention, as shown in FIG. 1, the explosion-proof band 5 wound around the cathode ray tube 1 is cut with a cutter or the like, and the cut end of the explosion-proof band 5 is peeled off from the surroundings of the cathode ray tube 1, and the peeling is performed. As shown in FIG. 2, the end 6 is sandwiched from the front and back by a plurality of, for example, four bar-shaped claws 7 having a diameter of, for example, 16 mm, which are adjacent to each other, as shown in FIG. The band 5 is wound around the vertical axis common to the claws, for example, clockwise, and at the same time, the cathode ray tube 1 also has the same direction, for example, a clock, around the center of the surface of the panel 2 and the axis passing through the neck portion 4. Rotate in the direction. At this time, the wound band 5 is guided by the L-shaped guide 8. As a result, the wound band 5 becomes, for example, a small lump 9 having a diameter of 150 mm as shown in FIG. It becomes easy.

棒状の爪７は、防爆用バンドを挟むことのできる２本以上を備えればよいが、好ましくは４〜６本がよい。４本以上であればバンドのつかみ易さが向上し、６本を超えると設計コストが高価となってしまう。爪７の直径はバンド５の厚みや強度にもよるが、１０〜２０ｍｍであればよい。爪７の材質には、例えば焼入れ丸鋼などを使用できる。   The bar-like claws 7 may be provided with two or more that can sandwich the explosion-proof band, but preferably 4 to 6 are used. If it is four or more, the band is easy to grasp, and if it exceeds six, the design cost becomes expensive. The diameter of the claw 7 may be 10 to 20 mm, although it depends on the thickness and strength of the band 5. As the material of the claw 7, for example, hardened round steel can be used.

バンド５の巻取り時の回動速度は、例えば１０〜２００ｍｍ／ｓとすることができる。   The rotation speed at the time of winding the band 5 can be set to 10 to 200 mm / s, for example.

Ｌ型ガイド８は処理対象のブラウン管の大きさによるが、一辺を３０〜１００ｃｍ程度とすることができる。Ｌ字型の内角は６０°〜１２０°であればよい。Ｌ型ガイド８の材質には、例えばステンレス鋼などを使用できる。   Although the L-shaped guide 8 depends on the size of the cathode ray tube to be processed, one side can be about 30 to 100 cm. The inner angle of the L shape may be 60 ° to 120 °. As the material of the L-shaped guide 8, for example, stainless steel can be used.
