The loader 38 is provided with a tire detection switch 38a. When the loader 38 is lowered onto the green tire Ag placed at a predetermined position, the tire detection switch 38a is set to the green tire A.

There are many. Therefore, in the following description, the drawings used in the above-mentioned conventional technique are appropriately used, the common elements are denoted by the same reference numerals, and differences are described each time. The control program setting device 1 for a tire vulcanizer according to the present embodiment is installed in a control device 41, like the conventional control program setting device 50 described above. As shown in FIG. 1, the control program setting device 1 for a tire vulcanizer according to the present embodiment stores a reference control program for a series of operations of the tire vulcanizer 30 '(a reference program storage means). And loader 3 for vulcanization
8, a green tire width detecting unit 2 (corresponding to a predetermined value detecting means) for detecting the width of the green tire during a series of operations by the press 37 and the unloader 39, and detecting a lower mold thickness during the series of operations. A lower mold thickness detector 3 (corresponding to a predetermined value detector), the green tire width detected by the green tire width detector 2, and a lower mold detected by the lower mold thickness detector 3; Using the thickness, the above RO

The information necessary for the setting operation of the control program, that is, the position data that changes depending on the type of tire to be vulcanized, is shown in (1) to (4) above. However, in the tire vulcanizer 30 'according to the present embodiment, the position data shown in the above (4), that is, the unloader 39 is lowered when the unloader 39 is lowered to capture the vulcanized tire on the lower mold. The stop height is not controlled by the control device 41 based on the detection output from the position sensor, but is automatically recognized by a tire detection switch installed on the unloader 39, like the loader 38. Also, the position data shown in the above (3), that is, the stop height of the upper mold fixing member 33 in a state where the upper mold 34 is lowered by the press 37 and the mold is closed, is also determined by the position sensor. Instead of being controlled by the control device 41 based on the detection output of the above, the lowering amount of the upper mold fixing member 33 is fixed, and the thickness of the mold is controlled by a mold thickness adjusting mechanism (not shown) installed in the press 37. The difference is absorbed. Therefore, in the present embodiment, (3) and (4) of the position data described in (1) to (4) above are not required for the operation of setting the control program.

A series of automatic processes of the loader 38, the press 37, and the unloader 39 related to the ordinary vulcanization molding process are started. During the loading operation of the green tire into the press 37 by the loader 38, the green tire width and the lower mold thickness detector 3 detect the green tire width and the lower mold thickness. Based on the detected green tire width and lower mold thickness, the CPU 53 determines the RO value.
The reference control program stored in M54 is corrected, and a control program is immediately created for the vulcanization target tire to be vulcanized. The subsequent vulcanization process, that is, the loader 3 according to the created control program.
The process from the loading of the green tire into the shaping position by 8 and the unloading of the vulcanized tire by the unloader 39 proceeds. At the same time, the created control program is stored in the control program memory 45 of the control device 41, similarly to the conventional control program setting device 41. Next time, when vulcanizing the same type of tire, the control device 41 calls the control program from the control program memory 45 and automatically operates the tire vulcanizer 30 'according to the control program.

Hereinafter, the green tire width detecting section 2 and the lower mold thickness detecting section 3 will be described in detail with reference to FIGS. The green tire width detector 2 is provided with a tire detection switch 38 installed on the loader 38.

In FIG. 2, h1 is the height detected by the position detection unit 38b, h2 is the distance in the height direction from the position detection unit 38b to the tire detection switch 38a, and h3 is the height of the upper surface of the tire mounting table 4. Indicates As is clear from the figure, the width Wg of the green tire Cg to be obtained is expressed by the following equation. Wg = h1-h2-h3 Here, h2 and h3 are constants, and h1 is a value detected by the position detection unit 38b. Therefore, the width Wg of the green tire Cg can be easily and quickly calculated by the calculation unit. You can ask. In addition, the lower mold thickness detector 3
Is composed of the position detection unit 38b, a distance measurement unit 38c installed on the loader 38 and measuring the distance between the loader 38 and the upper surface of the lower mold 32, and a calculation unit (not shown).
FIG. 3 shows a state where the loader 38 captures the green tire Cg and swings into the press 37 (or a state where the green tire Cg is thereafter descending). In FIG. 3, h1 is the height detected by the position detector 38b, h4 is the distance from the position detector 38b to the upper surface of the lower mold 32, and h5 is the height of the upper surface of the lower mold fixing member 31. Show. As is clear from the figure, the thickness W32 of the lower mold 32 to be obtained is expressed by the following equation. W32 = h1-h4-h5 Here, h5 is a constant, and h1 is the position detection unit 38.
The value detected by b, h4 is the distance measurement unit 38c

The CPU 53 corrects the reference control program stored in the ROM 54 on the basis of the detected values of the green tire width and the lower mold thickness, and calculates the vulcanization target tire that is currently performing vulcanization processing. Is immediately created, and the subsequent vulcanization is controlled according to the control program. Therefore, when vulcanizing and molding a new tire, there is no need to perform any prior setting processing by the operator as in the conventional case.

[0014]

The constructions of the green tire width detecting section 2 and the lower mold thickness detecting section 3 are not limited to those described in the above embodiment, but require a special setting operation or the like by an operator. Anything is acceptable. For example, the lower die 32 is pressed by a press 37 as the lower die thickness detection unit 3.
It is also possible to use means for automatically measuring the thickness of the lower mold 32 when it is mounted on the lower mold. Further, in the above-described embodiment, the newly created control program is stored in the control program memory 45 of the control device 41 as in the case of the conventional control program setting device 41, and is used for the next vulcanization processing of the same type of tire. However, since the control program setting device 1 creates a control program during the vulcanization process,
It is not necessary to store the control program in the memory as described above, and the control program can be created and controlled for each vulcanization process. In this case, since the thickness of the lower mold or the like is detected for each operation, accurate control can be performed even when the thickness of the lower mold or the like slightly changes due to heat or the like. It becomes possible. Further, the control program memory 45 for storing the control program becomes unnecessary.
