ング装置に関するものである。[Detailed description of the invention] [Technical field of the invention] The present invention relates to an exhaust pipe cutting device, and in particular to an exhaust pipe that removes unnecessary parts of the exhaust pipe after evacuating and sealing the inside of a cathode ray tube through the exhaust pipe. This invention relates to a cutting device.

Normally, in the exhaust process of a cathode ray tube, various treatments such as heating the glass envelope, high-frequency heating of the electron gun, and decomposition activation of the cathode are performed, and then the glass exhaust tube is melted with an electrically sealed heater. After sealing, the exhaust pipe is removed using an exhaust device and placed on a cutting device, and the unnecessary portion of the exhaust pipe on the opening side of the melted portion is removed by the exhaust pipe cutting device, thereby completing the exhaust process.

る。 However, moving the cathode ray tube from the exhaust equipment to the exhaust pipe cutting equipment in this way is difficult because the temperature of the cathode ray tube immediately after leaving the exhaust furnace is over 100 degrees Celsius, and there is a risk of implosion. An example of an exhaust pipe cutting device that automates the cutting process is shown in Japanese Utility Model Publication No. 53-5475. However, in the technology described in this publication, a file blade is used as a cutter, and as the advancing/retracting table advances, a pressure of about 1 kg is applied to the predetermined cutting part to damage it, and after the advancement, the cutter is cut from the opposite side of the file blade. The unnecessary portion is removed from a predetermined cutting portion by operating a hammer on the unnecessary portion. That is,
Since the file blade damages the exhaust pipe while moving, it has an extremely short lifespan and must be replaced once or several times a day, resulting in extremely low work efficiency.

長さが一定しないという問題がある。 In addition, a heater capture arm and a file are fixed to the same lifting table via cylinders, and the heater capture arm seals the exhaust pipe, captures the electrically sealed heater, and lowers it by the lift table. Since the structure is such that unnecessary parts of the exhaust pipe are damaged by a file fixed to the same lifting table in the lowered position, there is a problem that the length of the exhaust pipe remaining on the cathode ray tube side is not constant.

That is, the present invention includes a movable tube holder on which a cathode ray tube whose exhaust pipe has been completely sealed and exhausted by an exhaust device is placed, and a neck portion of the cathode ray tube placed on this tube holder is positioned and fixed. Netsuku support part,
A cutter presses against and damages a predetermined part of the exhaust pipe of a cathode ray tube whose neck is positioned by the neck support, and a cutter which detects the outer pin of the cathode ray tube whose neck is positioned by the neck support and moves the cutter against the exhaust pipe. a positioning part that determines the position;
It is located on the forward side of the pipe holding part that moves with the part damaged by the cutter as the forward side, and as the pipe holding part moves, it comes into contact with the forward side of the unnecessary part of the exhaust pipe that has been damaged by the cutter. This is an exhaust pipe cutting device characterized by being equipped with a cutting part for cutting unnecessary parts, and the cutter is made of a straight blade made of cemented carbide, and the cutting edge of this straight blade is
In this embodiment, the groove is formed at an acute angle of 30°.

９により位置ぎめガイド８は後退する。 In the cutting section, the transferred color picture tube 1 is held by the tube holding section 2 located above the cutting section, and then the neck section 3 is supported by a neck support arm 6 that moves via a drive cylinder (not shown). Position and fix by the section. Furthermore, in order to determine the positional relationship of the cutter 17 shown in FIG.
As a result, the elevating table 13 rises until the positioning guide 8 hits the outer pin 4 implanted in the neck portion 3. When the limiter switch 7 attached to the tip of the positioning guide 8 hits the outer pin 4, the elevating table 13 stops rising. After the ascent stops, the positioning guide 8 is moved back by the drive cylinder 9.

カツテイングを終了する。 After the positioning guide 8 has retreated, the cutting arm 10 is moved forward together with the support member 12 by the drive cylinder 11, and the exhaust pipe 5 is moved forward as shown in FIG.
A straight-blade cutter 17 made of cemented carbide, such as Tungaloy (product), shown in FIG. damage the part. Next, move the cutting arm 10 backward,
Finish cutting.

けられた部分で切断除去される。 Next, the elevating table 13 is lowered by the worm gear 14, and when it stops at a predetermined position, the tube holding part 2 moves with the part damaged by the cutter 17 as the forward side, and as shown in FIG. The outer peripheral surface of the unnecessary part 51 on the opening side of the melted part melted by the heating of the electrically sealed heater of the exhaust pipe 5 hits the cutting part formed by the arm 18 provided halfway on the forward side of the exhaust pipe 5 , and this unnecessary part 5 1 is cut and removed at the part damaged by the cutter 17.
次に、カラー受像管は再び移載装置によりコン
ベアに移載されて次工程へ送られる。 Next, the color picture tube is again transferred to the conveyor by the transfer device and sent to the next process.

る。 By configuring the exhaust pipe cutting device as described above, it is possible to reduce the variation in the length of the exhaust pipe 5 remaining on the color picture tube 1 side by cutting off unnecessary parts and make it constant. This eliminates the need to reseal or cut the exhaust pipe because the remaining exhaust pipe is too long.
また、カツター１７を超硬合金製の直刃とした
ことによりカツター１７の寿命が約１カ月とな
り、従来のやすり刃に比較して大幅に向上した。 Furthermore, by using a straight blade made of cemented carbide for the cutter 17, the life of the cutter 17 is approximately one month, which is significantly improved compared to a conventional file blade.
