Description

Panel Package Assembly for Cathode Ray Tube

The present invention relates to a panel packaging assembly for a cathode ray tube, and more particularly, to a panel packaging for packaging the panel to store and transport a panel made of glass as a raw material, without fear of damage, more particularly constituting the front portion of the cathode ray tube. It is about improving the assembly.

In general, cathode ray tubes used in the manufacture of color televisions and computer monitors are panels that display actual screens, channels connected to the rear of the panels, and necks formed at the rear center of the channels. The panel is manufactured by melting a glass raw material in a high temperature melting furnace at 1500 ° C. and compressing the molten glass by a press. Compression molded panels are used as final screens after polishing, so they must have accurate curvature and maintain high cleanliness. Cathode ray tubes are generally pinned to such a panel to support the shadow mask, and then constitute a channel and neck to be manufactured and sold as a finished product. In some cases, however, only the panels are molded for molding and supplying only the panels as a part to the cathode ray tube manufacturer or for temporary storage for later use in the fabrication of the cathode ray tube.

A packaging box (Carton Box) is used for the packaging of the panel, and the packaging box is a situation in which a packaging method in which a panel is transported by an automation system after storing the panel therein is widely used.

The packaging box is a natural pulp must be used rather than a general corrugated cardboard mainly made of pulp and lime. The reason for this is that packaging boxes made of artificial pulp are not suitable for panels that need to maintain high accuracy because scratches on panels are highly likely to occur due to the included lime. No natural pulp is used.

However, since the packaging of the panel by the packaging box uses a packaging box made of paper packaging material made from natural pulp, the manufacturing cost is high, the strength is insufficient, and the risk of damage to the contents is increased, as well as durability. There was a problem that causes the pollution due to the increase in costs and waste generated by discarding after one use.

That is, first, as described above, since the packaging box must use natural pulp to preserve the quality of the panel, the cost of the packaging box made of natural pulp is usually 10 times higher than that of the cardboard made of artificial pulp. In addition, the packaging box may be used two or three times, but the recovery rate is extremely low, and is usually discarded for one company and is not recycled. The cost is huge.

Secondly, due to the fragility and careless handling of the packaging box, there is a high possibility that the panel contained therein is damaged, and thus, careful handling is required in handling the packaging box in which the panel is stored.

Thirdly, in the situation where the environmental problem is prioritized first of all, as described above, the packaging box is used only once and disposed of as waste, and thus, due to debris and debris generated from the packaging box and paper, as well as external environmental pollution, It is accompanied by a problem that the environment is poor.

In addition, the packaging box of the panel as described above has a problem that is difficult to apply to the packaging automation system.

That is, as described above, the cathode ray tube panel is usually manufactured by a glass manufacturer and then transported to a cathode ray tube manufacturer to be made into a finished product. Therefore, the panel is packaged in a separate packaging box and then transported to the cathode ray tube manufacturer. In the past, the panel is stored in a box packaging material made of paper and then stacked and transported on a wooden pallet. In order to carry out the work more effectively, in accordance with the recent automation trend, a packaging automation system including a conveying device composed of a plurality of conveyor devices and articulated robots has been developed. Conventional packaging boxes are structurally weak and durable. It is difficult to apply to the automatic packaging system because the durability of the conveyance on the conveyor and the strength of the grip of the robot is not maintained when the space is moved by the robot.

Therefore, in view of the conventional problems as described above of the present invention, the object is to maintain a sufficient strength structurally can be reused repeatedly, the panel packaging assembly for cathode ray tubes suitable for use in packaging automation systems To provide.
