This is the position of the loader when the green tire of the setting target tire is carried into the press and the green tire is placed on the fixed die of the mold. An example of the predetermined operating position of the press is an advance position of the movable mold when the mold is closed by operating the press and the mold is fully closed. Further, an example of the predetermined operation position of the unloader is that the vulcanized tire of the setting target tire is placed on the fixed mold, and the unloader is operated to move the vulcanized tire to a position where the vulcanized tire can be captured. The position of the unloader when The detection of each of the predetermined operation positions is detected by the sensor by performing a reading operation on the position data reading means when each of the loader, press, and unloader is moved to the predetermined operation position by the manual operation means.

The detected predetermined basic position data is data dependent on the height of the mold and the width of each of the green tire and the vulcanized tire. Since this position data is data unique to each tire, Given this position data, many other individual control data relating to each position data of the general tire reference control program stored as reference in the reference setting program storage means are calculated from the three position data. Thus, a control program for the setting target tire can be created. Therefore, when each of the position data is detected by the position data reading means, the individual control program calculation means corrects and calculates the individual control data of the general reference control program stored in the reference control program storage means, so that the individual setting data can be obtained. A control program for the target tire can be set.

After being taken out of the press 37 by 8, a cooling process is performed to complete the tire A. The VCL 38, the press 37, and the unloader 39 are each provided with a position sensor (not shown), and the detection output is input to the control device 9, and the control device 9 sets the input data to the individual control data of the control program. When the value becomes a value, control is performed so that each operation part performs a predetermined operation. Next, a description will be given of an embodiment of the setting program setting device for executing the setting of the control program for automatically controlling the tire vulcanizer 10 for each tire type as described above. In FIG. 1, a control program setting device 1 includes a ROM (reference control program storage means) 2 for storing a general reference control program for a series of operations of the tire vulcanizer 10, and performs the series of operations by remote control. A manual operation unit (manual operation unit means) 3 to be operated, and press sensors 4, VCL sensors 5, and unloader sensors 6 attached to the press 37, the VCL 38, and the unloader 39 to detect the respective operation positions.

And a CPU (individual program calculating means) 8 for correcting and calculating each set data of the general reference control program read from the CPU. The control program setting device 1 is provided in the control device 9 and functions by switching the control device 9 to a program setting mode.

The control program setting device 1 having the above configuration
The setting procedure for setting the control program for the tire B (setting target tire) will be described below. First, the lower mold 32b and the upper mold 34b of the tire B are mounted on the tire vulcanizer 10, and a green tire Bg of the tire B and a vulcanized tire Be are prepared. The tire vulcanizer 10 is remotely controlled by the manual operation unit 3, the green tire Bg is captured by the VCL 38, and the green tire Bg is loaded on the ascending and lower mold 32b as shown in FIG. 3C. When the green tire Bg is loaded on the lower mold 32b, by reading the position data reading unit 7, the operating position of the VCL 38 detected by the VCL sensor 5 is read, and the predetermined operation of the VCL 38 is performed. Is obtained. Next, the press 37 is remotely operated by the manual operation unit 3 to lower the upper mold 34b, and the mold is fully closed as shown in FIG.
By reading the position data reading section 7, the upper mold 34b detected by the press sensor 4 is read.
Is read, and the position data of the predetermined operation of the press 37 is obtained. Next, the vulcanized tire Be is placed on the lower mold 32b, the unloader 39 is remotely operated by the manual operation unit 3, and the vulcanized tire Be is captured by the unloader 39 as shown in FIG. By setting the state and reading the position data reading unit 7, the operating position of the unloader detected by the unloader sensor 6 is read, and the position data of the predetermined operation of the unloader 39 is obtained.

In order to set a control program for the tire B,
The operations performed by the operator need only be the above operations, and the predetermined operation position data of the VCL 38, the press 37, and the unloader 39 obtained by the above operations are input to the CPU 8. The CPU 8 calls a general reference control program from the ROM 2, performs a correction operation of the control data used in the general reference control program based on the respective predetermined operation position data, and creates a tire B control program. Since the created control program for the tire B is stored in the individual control program memory 11 of the control device 9,
Next, when vulcanizing the tire B by the tire vulcanizer 10, the controller 9 is set on the tire B, and the tire vulcanizer 10 is automatically operated according to the control program of the tire B. FIG. 6 shows the individual control data of the VCL 38 displayed on the display of the control device 9.
(Swing-in position), SWING OUT POS. (Swing-out position), IN DOWN POS. (In-fall position), etc. In the conventional configuration, touch the numerical values calculated using the formulas set for each. Although it was necessary to input each key from the key, in the configuration of this embodiment, the VC obtained by the control program setting device for each tire was obtained.
Based on the predetermined operation position data of L38, the CPU 8 calculates control data for each item for each tire shown in FIG. That is, since the general reference control program stored in the ROM 2 stores the general individual control data of the tire as a reference for each item shown in the figure, the reference value is the position of the detected VCL 38. Correction calculation is performed based on the data.

For example, the SWING IN POS. (Swing-in position) can detect the width of the green tire Bg (the height in the pressing direction in the configuration of the tire vulcanizer 10) from the detected position data of the VCL 38. So, VCL38
In order to prevent the green tire Bg from interfering with the components of the press 37 when the vehicle is swung in, it is necessary to adjust the width of the green tire Bg. Therefore, the correction calculation of SWING IN POS. (Swing-in position) may be performed based on the difference between the reference green tire width and the detected width of the green tire Bg. With respect to other individual control data, data that needs to be changed from the reference value is similarly corrected, and the corrected value of each item is changed and displayed at the position of DATA in FIG. FIG. 7 shows the individual control data of the press 37 and FIG.
As in the case of the CL 38, each control data of the general reference control program is corrected using the predetermined operation position data of the press 37 or the unloader 39 obtained by operating the control program. In the configuration of the above embodiment, the control program of the tire to be set is created by correcting the general reference control program stored in the ROM 2. However, the control program can be set in the ROM 2 when the tire vulcanizer 10 is installed. The data specific to the vulcanizer may be stored, and the control data may be calculated by the CPU 8 using this data and the detected predetermined operation position data.
