Next, the operation of the above embodiment will be described with reference to the flowchart shown in FIG.

First, the power is turned on (step 1), and the first
Buffer device 6 and second of the glass substrate manufacturing line 3 of
It is judged whether or not the storage cassette is set in the buffer device 9 of the glass substrate manufacturing line 4 (step 2), and if the storage cassette is not set in any of them, the process stands by.

When it is determined that the glass substrate G is set in step 2, the glass substrate G is transferred from the processing device 1 to the branching device 2, and in this branching device 2, the first glass substrate manufacturing line 3 and the second glass substrate The production lines 4 are sequentially branched and distributed.

Further, in the first glass substrate manufacturing line 3, the transfer processing signal S is exchanged from the upstream processing device 5, the buffer device 6 and the downstream processing device 7 to the synchronous operation device 12, respectively. And the buffer device 6
Then, it is judged whether or not the first glass substrate G1 is received from the upstream processing device 5 (step 3), and it waits until it arrives, and when it arrives, outputs the transport processing signal S to the synchronous operation device 12 (step 4). .

Similarly, in the second glass substrate manufacturing line 4, the transfer processing signal S is exchanged from the upstream processing device 8, the buffer device 9 and the downstream processing device 10 to the synchronous operation device 12, respectively. Then, the buffer device 9 judges whether or not the second glass substrate G2 has been received from the upstream processing device 8 (step 5), waits until it arrives, and when it arrives, outputs the transfer processing signal S to the synchronous operation device 12. (Step 6).

Then, when the synchronous operation device 12 receives the transport processing signal S from the buffer device 9, the transport processing signal S is output to the buffer devices 6 and 9 (step 7), and the downstream from the buffer device 6. Of the first glass substrate G1 and the second glass substrate G1 from the buffer device 9 to the downstream processing device 10 (step 8).
It is judged whether G2 has been sent out (step 9), and the process ends with the merchandising.

Further, the simultaneous dispensing conditions for the first and second glass substrates G1 and G2 in the first glass substrate manufacturing line 3 and the second glass substrate manufacturing line 4 are not set, and the first and second glass substrates G1 and G2 are fed from the synchronous operation device 12. When the transport processing signal S regarding the payout of the second glass substrates G1 and G2 is not sent, the buffer devices 6 and 9 load the first and second glass substrates G1 and G2 into the storage cassette set in the device. Store and take in the first and second glass substrates G1 and G2 as required,
Make a payment.

Further, the odd number of glass substrates G put into the processing apparatus 1 are used, and the first and second glass substrates G1 are provided in either the first glass substrate production line 3 or the second glass substrate production line 4. , G2, the extra first and second glass substrates G1 and G2 are stored in the corresponding cassettes of the buffer devices 6 and 9 of the first or second glass substrate manufacturing line 3 or 4, respectively. Be recovered.

In the assembling device 11, the synchronous operation device 12
Based on the above, the first glass substrate G1 manufactured in the first glass substrate manufacturing line 3 and the second glass substrate G2 manufactured in the second glass substrate manufacturing line 4 are opposed to each other to form a liquid crystal cell. To do.

Specifically, for example, it is assumed that 25 glass substrates G are loaded into the processing apparatus 1. Glass substrate G is 1
The pieces are continuously flowed one by one, and are alternately distributed to the first glass substrate manufacturing line 3 and the second glass substrate manufacturing line 4 by the branching device 2. It is assumed here that the processing speed of the first glass substrate manufacturing line 3 is faster than that of the second glass substrate manufacturing line 4.

Then, the first divided by the branching device 2
The second glass substrates G1 and G2 are processed in the first glass substrate manufacturing line 3 and the second glass substrate manufacturing line 4, respectively, and reach the respective buffer devices 6 and 9, but the first glass substrate The processing speed of the production line 3 is the second
Since it is faster than the processing speed of the glass substrate manufacturing line 4, the first glass substrate G1 flowing through the first glass substrate manufacturing line 3 reaches the buffer device 6 first.

Further, the downstream processing devices 7 and 10 located downstream of the respective buffer devices 6 and 9 output the carrying processing signal S for notifying the buffer devices 6 and 9 of the receivable state. The processed signal S is transferred to the buffer device 6,
It is sent to the synchronous operation device 12 before it reaches 9.

Here, in the synchronous operation device 12, since the buffer device 9 of the second glass substrate manufacturing line 4 is not ready to dispense to the second glass substrate G2, the transfer processing signal S related to substrate dispensing to the buffer device 6 is sent. Is not output. Therefore, the buffer device 6 is connected to the buffer device 9 by the second
Until the first glass substrate G2 arrives, the first glass substrate G1 that continuously flows is continuously stored in the storage cassette in the own device.

After that, when the second glass substrate G2 reaches the buffer device 9, the synchronous operation device 12 simultaneously outputs to the buffer device 6 and the buffer device 9 a transfer processing signal S relating to substrate delivery, and this transfer processing signal is output. In response to S, the buffer device 6 and the buffer device 9 simultaneously receive the first
And the second glass substrates G1 and G2 are dispensed.

Thus, the first glass substrate manufacturing line 3
And the second glass substrate manufacturing line 4 are synchronized with each other, at the same time, the first and second glass substrates G are provided to the assembling apparatus 11.
Supply 1, G2.

Then, the 25th glass substrate G is the first
If it is sent to the glass substrate manufacturing line 3 of
The glass substrate G1 is stored in the storage cassette of the buffer device 6. That is, the synchronous operation device 12 includes the first and second
Since the payout conditions for the glass substrates G1 and G2 are not met, the transfer processing signal S related to the payout of the substrates is not output to the buffer device 6. As a result, the first glass substrate G1 remains stored in the storage cassette of the buffer device 6,
It is taken out and collected together with the storage cassette after the end of sale.

Therefore, when the lots are merchandised, when the first or second glass substrates G1 and G2 are left over at the end of each lot due to management, the next lot is merchandised. Before each time, the first or second glass substrate G1, G2
Eliminates the need to remove. That is, since the extra first or second glass substrates G1 and G2 do not flow to the assembling device 11 and remain in the storage cassettes in the buffer devices 6 and 9, they can be easily and quickly collected.

According to the above embodiment, the two first and second glass substrates G1 and G2 for supplying the first and second glass substrates G1 and G2 to the assembling apparatus 11 for assembling the first and second glass substrates G1 and G2 are used. Synchronous operation device for glass substrate production lines 3 and 4
By performing the synchronization by 12, the first and second glass substrates G1 and G2 are not sent to the assembling apparatus 11 and only two of them are always at the same time.
Can supply G1 and G2. Therefore, since the first or second glass substrate G1, G2 is no longer held in the assembling apparatus 11, it is not necessary to take down the first or second glass substrate G1, G2 after the assembling apparatus 11 is once lowered. Further, it is possible to avoid troubles such as damage and breakage that occur when the first or second glass substrate G1, G2 is taken out of the assembling device 11.

Further, with respect to the recovery of the surplus first and second glass substrates G1 and G2 in the commercial product, the buffer device 6,
The first and second glass substrates G1 set to 9
G2 can be easily and quickly done from the storage cassette.
