  2. Description of the Related Art Conventionally, in the production process of a roll-shaped product, an operation of actually operating a manufacturing apparatus and setting operating conditions while confirming the quality state of the roll-shaped product is performed before manufacturing a product. However, in such a method for setting operating conditions, the operator's hand is troubled each time, and the work cannot be simplified. There was a problem that it cost.

  On the other hand, recently, operating conditions have been registered in advance, and by setting the corresponding operating conditions from the operating conditions registered for each product type before product manufacture, the results of reducing the operating condition setting workload have been achieved. It has been. However, in such operating condition setting methods, the registered operating conditions are often not the optimal operating conditions that reflect the actual manufacturing equipment state or product quality state. It is necessary to operate the apparatus and readjust the operating conditions while confirming the quality state of the roll-shaped product (see Patent Document 1).

Prior art documents are shown below.

It is possible to provide an optimum operating condition setting system that can be used.

  Hereinafter, details of the present invention will be described with reference to the drawings. However, the following content is one embodiment and example, and is not limited to the following content.

  As shown in FIG. 1, the optimum operating condition setting system of the present invention includes operating state data (line speed, coating solution viscosity, oven furnace temperature, etc.) of each unit of the manufacturing apparatus and auxiliary devices (10-13). ) Is measured by various sensors attached to each unit and the accompanying devices (10 to 13), and obtained as operation state data (14).

  Moreover, the quality state of the roll-shaped formed product manufactured by the manufacturing apparatus (10-13) is inspected by a quality inspection apparatus such as a defect inspection apparatus (20) or a film thickness meter (21), and as quality inspection data (22) obtain.

  In addition, the operating conditions (15 of each unit and the accessory devices (10 to 13) of the manufacturing apparatus and the accessory devices (10 to 13) are changed to the operating conditions (15 ) Get as.

  The operating state data (14), operating conditions (15), and quality inspection data (22) obtained as described above are sent to the processing device (30). In the processing device (30), an optimum operation condition calculation process is performed from the operation state data (14) and the quality inspection data (22).

Next, the flow of the optimum operating condition calculation process will be described using FIG. 1 and FIG.
First, the operation state data (14), the quality inspection data (22), and the operation condition (15) of each unit of the manufacturing apparatus and the auxiliary devices (10 to 13) are monitored (step 1), and the operation state data (14). A line speed check (step 2) is performed to determine whether the line speed is equal to or higher than a line speed judgment value input in advance.

  As a result of the line speed check, if the line speed is less than or equal to the line speed determination value, the line speed check is repeated, that is, Steps 1 and 2 are performed.

  Here, as a result of the line speed check, if the line speed is equal to or higher than the line speed determination value, the operation state data (14) and quality inspection data (22) acquired in step 1 and the target values of each data input in advance The quality stable manufacturing state check (step 3) is performed to determine whether the difference from the target value is within the allowable range. The allowable range here is arbitrarily defined.

  As a result of the quality stable manufacturing state check, if the operation state data (14) and the quality inspection data (22) are not within the allowable range, the operation state data (14), the quality inspection data (22), and the operation condition (15) are newly added.
