To the processing stage 32B (steps 238 to 242) to mold a raw case assembly of a predetermined size on the molding drum 104.

Here, in step 240, it is confirmed whether the molding carriage 20 can be moved to the inspection stage 90, and when the molding carriage 20 is movable (affirmative determination), the molding carriage 2 is moved.
0 is moved from the processing stage 32B of the ST attaching unit 32 to the inspection stage 90 (step 242). At the inspection stage 90, the raw case assembly formed on the forming drum 104 is inspected. When this inspection is completed (confirmed in step 244) and the raw case assembly being molded conforms to the standard, the transfer section 34 is instructed to move to the processing stage 34B (step 250). As a result, the molding carriage 20 moves to the processing stage 34 (B) of the transfer unit 34 and stops at a predetermined position. In addition, when a defect occurs from the inspection result (step 246
If the determination is negative, the process proceeds to step 248 and error processing is performed.

On the other hand, as shown in FIG. 13, in the BT band forming step 14, the same processing as that in the green tire forming step 12 is performed. In the first step 300 of this flowchart, the forming carriage 21 used for forming the BT band assembly is selected and moved from the charging standby path 62 to the home position 98.

In the next step 302, a work instruction is given to the forming dolly 21, that is, the stage is moved to the stage B of each processing section in order and the BT band assembly of a desired size is formed into the forming drum 1.

~ 330).

After these processes are completed, the forming carriage 2
1 is moved to the inspection stage 94, and the BT band assembly formed on the BT drum 105 of the forming carriage 21 is inspected by the inspection stage 94. Steps 332, 33
In step 4, after confirming the end of the inspection in the inspection stage 94 and the inspection result and confirming that the BT band assembly is formed according to the standard, in step 338, the molding carriage 21 is moved to the processing stage 34B of the transfer section 34. Instruct them to move. When a negative determination is made in step 334, the process proceeds to step 336 and error processing is performed.

In the transfer section 34, when the molding carriage 21 on which the BT band assembly is molded stops at a predetermined position, the BT band assembly is taken out from this molding carriage 21.

When the transfer unit 34 confirms that the BT band assembly has been taken out from the BT drum 105 (affirmative determination in step 340), it is then determined whether or not the molding of the BT band assembly is completed using this molding carriage 21. If the next process is performed (negative determination) (step 342), the process returns to step 300. Further, when the processing is to be ended (affirmative determination), the molding cart 20 is moved to the charging standby path 62, and if necessary, the charging processing is performed, stopped and waited (instructed in step 344), and the processing is ended.

On the other hand, as shown in the flowchart of FIG. 12, the BT is attached to the raw case assembly at the transfer section 34.
The band assembly is assembled and the transfer unit 3
When it is confirmed that the processing in step 4 has been completed (Yes in step 252) and that the raw tire stitching section 36 can be moved to the processing stage 36B (Yes in step 254), the forming cart 20 is instructed to start the movement (step 256).

The raw tire stitching section 36 starts the process when the molding carriage 20 stops at a predetermined position, and outputs the end of the process to the host computer 170 when the process is completed. When the host computer 170 confirms this (affirmative determination in step 258), it is confirmed whether the molding carriage 20 can be moved to the inspection stage 92 (step 260), and the molding carriage 20 is moved to the inspection stage 92.

At the inspection stage 92, the molding drum 104
Inspect whether or not the raw tire is molded according to the standard according to the size.

When the inspection at the inspection stage 90 is completed (confirmed at step 264) and the molding is performed as specified (affirmative determination at step 266), the molding carriage 20 is moved to the processing stage 38B of the take-out section 38. Is instructed to move (step 268).

In the take-out section 38, the green tire formed on the forming drum 104 of the forming carriage 20 is taken out from the forming carriage 20 and stored or conveyed to the next vulcanization step.

At step 270, when it is confirmed that the green tires have been taken out from the molding carriage 20, it is judged whether or not the next molding processing is to be carried out by this molding carriage 20 (step 272), and the next processing is carried out. In the case (negative determination), the process proceeds to step 200 and a new instruction is output. Further, when the processing by the molding carriage 20 is finished, the molding carriage 20 is moved to the charging path 56, the charging processing is performed if necessary, and then moved to the standby path 58 (step 274).

As described above, in the tire automatic molding system 10 of this embodiment, a large number of molding carriages 20 and 21 are used to mold not only tires of the same size but also tires having different tire widths and rim diameters. Can also be done in parallel. For this reason, it is possible to smoothly mold a wide variety of tire sizes without changing the setting of each processing unit or changing the members supplied to each processing unit in order to change the tire size to be molded. It can be carried out.

On the main traveling paths 50 and 60, there is only the molding carriage 20 or the molding carriage 21 which moves to the next processing section,
Since the other molding carriages 20 and 21 are processed in the pull-in path 52, even if they are moved along the same path of a large number of molding carriages 20 and 21, their mutual movements are not hindered and smooth. It is possible to move.

Further, since the address mark 66 (66A, 66E, 66H) is preliminarily provided in front of the address mark 66 for changing the course of the molding carriage 20 or stopping, the molding carriage 20 is relatively fast in the straight line portion. It is possible to travel at a high speed, the molding carriages 20 and 21 can be smoothly and reliably moved, and a large amount of tires can be molded in a short time. In addition, in the present embodiment, the number of processing stages according to the type of tire to be molded is provided in each processing portion, but in the case where the same member can be used among tires of different sizes, different processing sizes are used. Even tires may be set so as to share the processing stage, which makes it possible to efficiently form many types of tires.

Further, in the present embodiment, the forming truck 104 or the BT drum 105 is attached to the bracket 102, and the traveling vehicle 2 traveling by the unmanned traveling apparatus 100.
Although 0 and 21 were used, the configuration and shape of the forming carriage applied to the present invention are not limited to this, and each processing unit is moved by automatic traveling to sequentially form a raw case assembly, a BT band assembly, and a raw tire. Any material that can be molded is applicable.

Further, in this embodiment, the forming carriage 20 and the forming carriage 20 are respectively formed by different running lines 16 and 18 formed in loops.
The automatic tire forming system 10 divided into the raw tire forming step 12 for moving 21 and the BT band forming step 14 has been described, but it may be configured to move only the forming carriage 20 in one traveling line. The processing unit may be arranged along three or more different traveling lines.

Furthermore, it is easy to make a part of the tire forming system a fixed drum type, for example, the forming carriage 2
1 in place of the BT band forming process 14 that is running,
It may be configured by arranging a plurality of normal BT band forming machines.

It should be noted that each of the tire molding steps described in this embodiment does not limit the configuration of each processing section of the tire molding system to which the present invention is applied, and the processing section may be deleted or added as necessary. It can be carried out. For example, move the molding trolley to the manufacturing equipment for some of the components and directly attach the manufactured components, or vulcanize the molding trolley (vulcanizer).
It can be easily configured so that the completed raw tire is directly passed to the vulcanizer after being driven up to. At this time,
The guide tape 64 may be attached according to a predetermined standard, the main running paths 50 and 60 can be extended, and the bypass (for example, the sub running path 54) to the main running paths 50 and 60 can be easily set, and a more appropriate tire can be obtained. It is possible to build a molding system.
