【発明の詳細な説明】 〔産業上の利用分野〕 本発明はカラーブラウン管の螢光体塗布装置に関する。[Detailed description of the invention] [Industrial application field] The present invention relates to a phosphor coating device for color cathode ray tubes.

置している。Conventionally, as a fluorescent coating device, for example, Japanese Patent Application Laid-Open No. 57-1
No. 03232 is known. This structure has three phosphor processes for green, blue, and red, and a phosphor coating machine, and an exposure table and transfer device are placed between these three phosphor coating machines. are doing.
上記従来技術は、品種への対応は考慮されているが、前

悪化を招いていた。In other words, if we try to reduce the number of processing positions of the phosphor coater in conjunction with a reduction in the number of work starts, it is possible to reduce the number of processing positions where the same process is consecutively arranged. If it consists of one position, it is difficult to integrate or reduce each position, and the efficient production number is self-limited. Furthermore, when the minimum number of positions for a phosphor coating machine is determined, the size of the apparatus increases in proportion to the external dimensions of the cathode ray tube to be constructed, leading to a deterioration in space utilization.
本発明の目的は、小量生産においても空間利用効率が高

塗布装置を提供すること１こある。An object of the present invention is to provide a phosphor coating device for color cathode ray tubes that has high space utilization efficiency even in small-volume production and has stable product quality.
ところで、螢光体プロセスは、■螢光体スラリー塗布、

It is a combination of ■Drying, ■Exposure, ■Development, ■Drying, etc.
This order is common to the three color phosphors of green, blue, and red, and other processes can be shared by simply switching the injection of the phosphor slurry for each phosphor.

。Therefore, it is conceivable to place the minimum number of coating machines required for these five processes as processing positions and circulate the panel up to three times.In this way, the operating rate will be reduced even in small-scale production. However, if these conditions are simply realized as shown in Figure 3, the logistics of upstream and downstream processes (this continuity However, due to the process conditions, it becomes an unstable factor and causes a decline in product quality.

し換える移載装置とを備えた構成により達成される。The above purpose is to provide a phosphor coating machine that has a carrier head in which the total number of carrier heads is set to a common multiple of the number of cycles and the number of products that can be simultaneously started, and each carrier head is assigned a carrier head number that identifies the product type and the number of cycles. , 1 for every cycle of panels loaded onto the carrier head.
This is achieved by a configuration including a transfer device that transfers a panel on a carrier head number that does not reach the predetermined number of circulations by 1 to a carrier head of the same type with a carrier head number that has a number of circulations one more than the carrier head number. be done.

キャリアヘッド番号の割付けにより、比較的簡単なシス
テム構成で、多品種の同時着工が可能となる。The phosphor coating machine is equipped with 11 carriers that are a common multiple of the number of cycles and the number of products to be manufactured. Further, the carrier head has a carrier head number corresponding to the start of construction 8 and the number of circulations l. Since panels are loaded while checking the type of panel itself and the carrier head number of the phosphor coating machine, the same sequence of logistics is repeated. Therefore,
By assigning carrier head numbers, it is possible to start work on a wide variety of products at the same time with a relatively simple system configuration.

均一なためである。That is, the panel that has passed once on the phosphor coater is taken out by the take-out transfer machine and then reinserted into the next circulating carrier head. The panels that have completed the final circulation are taken out and then transported to the next process. As a result, the processes before and after the phosphor coating machine operate as their takt time, which is the value obtained by multiplying the takt time of the phosphor coating machine by the number of cycles, thereby stabilizing the process conditions. . That is, the number and distribution of panels of each circulation number are uniform within the phosphor coating machine, and the composition and distribution of panel types are also uniform in the processes before and after the phosphor coating machine.

循環回数をＬ（Ｌは２以上の任意の整数）とし、同時着
工品種数をＭ（Ｍは任意の整数）とすると。An embodiment of the present invention will be described below with reference to FIGS. 1 and 2. As shown in FIG. 1, the phosphor coating machine 20 for color cathode ray tubes is equipped with carrier heads 23 from an input position 21 to an output position 22, and each carrier head 23 moves one position per takt time. Move the machining position step by step. carrier head 2
For the total number of 3, let the number of times the panels are circulated through the phosphor coater 20 be L (L is any integer greater than or equal to 2), and the number of products that can be started at the same time is M (M is any integer).

xN (N is any integer). Here, the number M of products that can be simultaneously started is the maximum capacity of the phosphor coating machine 20, and for example, a phosphor coating machine 20 that has the ability to handle three types A, B, and Ct.
When operating normally with two types, A%A%B'P
It is sufficient to adopt a combination of B, B, and C, and it is also possible to deal with one type of product by adopting a combination of A, A, A or B, B, and B.

Therefore, if N is set to 2, the total number of carrier heads 23 becomes =3x3x2=18. This specific example will be explained below.

At the same time as it is taken out and sent back to the transfer machine 30 via the orthogonal transfer machine 28, the number of circulations is added by one. Then, when the orthogonal transfer machine 25 analyzes that the carrier head 23 whose circulation number is one more than the carrier head number from which the panel was taken out is located at the input position 21, the input transfer machine From 2G, the carrier head 23 of the carrier head number is loaded. In the state shown in FIG. 1, the carrier head number A2 is located at the take-out position 2'21, so if this panel is taken out by the take-out transfer machine 271, the orthogonal transfer machine 28, the return transfer machine 30 and the orthogonal transfer machine 25, when the carrier head 23 with the carrier head number A3 is located at the loading position 21,
The carrier head 231 with the carrier head number A3 is loaded from the container transfer machine 26.

図れる。In addition, the process upstream from the input conveyor 24 and the process downstream from the take-out conveyor 29 are based on the operation of the phosphor coater 20 as shown in FIG. Operates using the value as takt time. In this operation, compared to the cases shown in Figures 3 and 4, the equipment capacity in upstream and downstream processes can be designed based on the average capacity rather than the maximum capacity of the standard tact, and a buffer for equalizing logistics can be used. etc. installation is also unnecessary. Furthermore, by equalizing logistics, the waiting time for panels between processes is also equalized, resulting in stable process conditions and product quality.
