Description

Detailed Description of the Invention [Technical Field of the Invention] The present invention relates to a screen forming line that completely automates the process from cleaning the panel of a color cathode ray tube to forming an aluminum film. This invention relates to a charging method and device.

[Technical background of the invention] As shown in Japanese Utility Model Publication No. 59-37955, in the screen forming line of color cathode ray tubes, a black stripe film, a soot film, a fluorescent film,
Multiple application steps are required to form the film coating and the aluminum coating.

When automating a series of these processes to form an automatic coating line, it takes a long time of 1 to 2 hours from panel input to completion of coating, so it is necessary to remove defective products from the automatic line midway through line operation. It is necessary to take measures such as re-feeding panels partially coated with phosphor to the automatic line midway through the process.

In other words, efficient removal of panels in the middle of a process that involves stopping the automatic line and re-insertion of panels in the middle of the process is an important point in improving the operating rate of the automatic line.
There is. In addition, a method and apparatus for inserting panels in the middle of the process for trial production and film thickness control have been desired.

Next, a conventional method for removing and reinserting panels and masks will be described with reference to FIG.

] In this conventional example, a Doug coating machine 1 for the black stripe matrix coating process and a blue phosphor coating machine (hereinafter referred to as blue machine) 2 for coating the first color phosphor (hereinafter referred to as blue machine) are operated continuously. This is an example in which a panel from which a defective panel has been removed or a black stripe matrix coating process has been completed is fed into an automatic line again.

The panels on the conveyor 3 are combined with the mask.
The PM shown in t) is separated into a panel P and a mask M by a panel/mask separation device 4. And the panel [) is
The panel transfer machine 5 transfers the mask M to the loading conveyor/6 of the DAG coating machine 1, and the first mask transfer machine 7 transfers the mask M to the first mask storage! ! Transferred to i@8.

Then, the panel P on which the Doug coating has been completed is conveyed to the inspector 10 by the unloading conveyor 9, and the blacks 1 to the live matrix coated panels P1 are inspected on the inspection table 11.

At this time, if this panel P1 is defective, this panel is removed from the automatic line by the inspector, and the mask M1 corresponding to this panel P1 is removed from the conveyor 12 by the inspector 10's removal command. It is taken out after passing through. Reference numeral 13 denotes a second mask transfer machine, which transfers masks corresponding to non-defective panels onto the conveyor 15 of the second mask storage device 14.

On the other hand, as the panel P1 is removed, the body becomes empty, so the reloading operator 21 transfers the black stripe matrix formed panel P2 and the corresponding mask M2 to the panel transfer machine 1722 and the mask M2, respectively. The mask M2 is automatically transferred to the conveyor 15 of the second mask storage device 14 by the third mask transfer device 25. The panel P2 is loaded from the panel conveyor 22 to the blue machine 2.
After being processed by this machine, the unloading conveyor 26 carries out the next step of applying the second color phosphor.
The culm is transported to the green phosphor coating machine.

[Problems with front lighting technology]

In this way, conventionally, when removing and reinserting panels and masks in a series of continuous machines, human intervention was required, and panels and masks could only be reinserted into empty positions, making it difficult to re-inject them. Because of the limited number of panels, a person is always on standby and has to put panels into the vacant positions of the removed panels at 4', which is inefficient. In addition, troubles such as machine stoppage due to re-loading errors are likely to occur, which is also a cause of lowering the operating rate of the color cathode ray tube manufacturing line.

[Purpose of the invention]

(Summary of the Invention) The method of inserting panels P and σ masks M in the middle of the present invention is performed in conjunction with panel and mask removal commands in a color cathode ray tube screen forming line that automates the process from panel cleaning to aluminum coating forming of color cathode ray tubes. Then, those of the same type as the removed panel P1 and mask M1 are selectively taken out from among the waiting panels and masks of various types, and are automatically put into the empty positions of the removed panels and masks. It is something.

Furthermore, the panel and mask mid-loading device of the present invention includes a pallet 31, etc., on which a pair of panels and a mask can be loaded, in a color cathode ray tube screen forming line that automates the process from panel cleaning to aluminum coating forming J culm of color cathode ray tubes. There is a sorting lane 41 in which these pallets are stored according to the same type, and the above pallets 3 are stored in the lane for this sorting.
The sorting mechanism 43 takes the pallets 31 out of the warehouse from the lane 41, and the output mechanism 44 takes out the pallets 31 from the lane 41. The masks and panels of the pallets t-t taken out by this delivery mechanism are formed into a series of screens. The line is equipped with transfer machines 48°1, 51, etc.

Then, at the same time that a command is issued to remove panel P1 and mask M1 from line 1, panels and masks of the same type as the removed panels and masks are automatically taken out from sorting lane 41, Inserted into automatic line.
