DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a split transport device for transporting a display device such as a cathode ray tube (CRT) in a divided manner without manual operation, and a split transport method for the display device.

[0002]

2. Description of the Related Art In recent years, recycling of resources and prevention of environmental destruction have been highlighted. In response to this request,
2. Description of the Related Art Research on recycling of a used television set or a cathode ray tube (CRT) for a monitor of a computer as an example of a display device is being conducted in various fields. Further, there is an urgent need to quickly and efficiently recycle an increasing number of discarded television sets. 2. Description of the Related Art A cathode ray tube is used as a television set or other image receiver, and is a glass structure having a panel portion (also called a face portion) and a funnel portion (also called a panel skirt portion). The panel section is made of almost transparent glass material to improve light transmittance, and the funnel section is made of lead to prevent leakage of X-rays generated by collision of a high acceleration voltage electron beam with a substance. It is made of glass material mixed with. The funnel portion and the panel portion are formed in a tubular shape by welding and shielding with frit glass (solder glass). An electron gun, a deflection yoke, and the like are attached to the back of the cathode ray tube in appearance. Inside the cathode ray tube, there is a shadow mask (or aperture grill)
Is provided, and on the fluorescent screen on the inner surface side of the panel portion,
Phosphors of three colors of red, green and blue are regularly applied.

By the way, in order to recycle this type of cathode ray tube, as shown in FIG. 28, the cathode ray tube 1 is divided into a panel portion 1P and a funnel portion 1F at a division surface 1a. The division surface 1a is different from the frit glass / shield edge surface 1b that shields the panel portion 1P and the funnel portion 1F, and the division surface 1a is located on the panel portion 1P side. The operator lifts the funnel portion 1F by hand and separates and transports the divided panel portion 1P and funnel portion 1F. FIG.
When the separated panel portion 1P is separated using a machine, the panel portion 1P is strongly gripped by the chuck 2, and the funnel portion 1F is strongly gripped by the chuck 3 to be separated and transported as shown in FIG. .

[0004]

However, when the operator separates and transports the panel portion 1P and the funnel portion 1F by hand as shown in FIG. 28, there are the following problems. That is, in the case of a large inch-size cathode ray tube, both the panel portion 1P and the funnel portion 1F are very heavy, and the work becomes heavy labor. Since the panel section 1P and the funnel section 1F have the glass dividing surface 1a, the two sections are separated and conveyed, so that the working environment is severe. When the panel unit 1P and the funnel unit 1F are firmly gripped and transported using the chucks 2 and 3 as shown in FIG. 29, the force of the chucks 2 and 3 is applied to the side surface of the panel unit 1P and the funnel unit 1F. There is a risk of damaging the side. In particular, since the funnel portion 1F has relatively low strength, the funnel portion 1F may be damaged when the chuck 3 sandwiches the funnel portion 1F.

If the funnel portion 1F or the panel portion 1P is damaged and fragments 4 and 5 are generated, the following recycling problem occurs. (1) When funnel glass is mixed with panel glass to be cullet and melted again, the panel glass is colored due to the influence of lead in the funnel glass and cannot be used as panel glass. For this reason, an operation of separating the funnel glass, which has been damaged by hand, from the panel glass by the operator is added, which significantly reduces the recycling productivity.
Alternatively, when sold as glass (mix glass) in which panel glass and funnel glass are mixed, the added value is significantly reduced.

(2) The cathode ray tube is broken at a position other than the division surface at the time of division. Discarded CRTs are subjected to unexpected external forces during the collection and dismantling stages. When applying heat from a heater to a cathode ray tube and performing division by thermal strain, the portion that has been subjected to an external force in advance will be broken and break. In particular, when the panel portion is broken, the method of gripping the side surface of the panel portion cannot transport the broken glass piece. In addition, a broken glass piece may fall during transportation. There is a problem that the broken glass piece gets caught or remains on the mechanism section of the dividing device or the conveyor transfer device, which causes each device to stop. The reason why the cathode ray tube is broken at the time of gripping is that the gripping force of the chuck 3 of the funnel portion and the chuck 2 of the panel portion is large, and the weight of each of the chucks 2 and 3 is large.
It is damaged by inertia and impact. Therefore, the present invention solves the above problem, the display device can be divided into a plurality of parts without manual operation and can be separately carried out, and even if a part is broken when the display device is divided and transported, It is an object of the present invention to provide a divided transport device of a display device and a divided transport method of a display device that can smoothly continue the dividing and transporting operation.
