In the tire forming system 10, the empty truck 20 stored in the storage yard 30 by the host computer 220 and the truck 20 loaded with the painted raw tires T are of course mounted on the truck 20. Also manages raw tires T.

That is, in the tire building system 10,
When the coating of the raw tire T is completed by the coating device 72, the communication head 226 provided in the coating area 26 outputs the finish time of the coating to the AGV 100. The painting end time is recorded in the ID tag 210 of the cart 20, and by reading the information of the ID tag 210, the elapsed time after the painting of the raw tire T, that is, the dry state, can be determined.

Host computer 220 to AGV1
00 transports the coated green tire T to the vulcanization area 24, and when the elapsed time reaches a predetermined time, the vulcanization area 2
The carriage 20 is placed sideways on a predetermined vulcanization stage provided in the carriage 4.

FIG. 14 shows an outline of the vulcanization area 24. The vulcanization area 24 includes a plurality of vulcanization stages 23.
0 is provided, and a vulcanizer is arranged at each vulcanization stage.

[0091] Each vulcanization stage 230 has a stop line 23 for traversing the carriage 20 to the vulcanizer 232.
4 is formed as a transfer line. Further, a passing line 236 through which the AGV 100 or the AGV 100 carrying the carriage 20 passes along the stop line 234 is formed as a traveling line.

When the AGV 100 travels along the passing line 236 and reaches a predetermined vulcanization stage 230, it moves horizontally or obliquely in parallel to the stop line 234, and lays the cart 20 sideways on the vulcanizer 232. In the vulcanization stage 230, the raw tires T are taken out from the carriage 20 laid sideways on the vulcanizer 232 by a loader 240 (only a schematic position is shown in FIG. 14) and loaded into a vulcanization mold of the vulcanizer 232 in order.

The AGV 100 having the cart 20 laid sideways on the vulcanizer 232 starts the following processing based on an instruction transmitted from the communication head 226 provided on the vulcanization stage 230. At this time, when the movement to the waiting yard 32 is instructed, the carriage 20 is lowered and moved to the waiting yard 32.

On the other hand, the vulcanizing area 24 has
A standby line 238 is provided along the line 36 on the side opposite to the vulcanization stage 230. In this standby line 238,
Next, the carriage 20 laid sideways on the vulcanizer 232 is stopped. That is, the AGV 100 that has transported the truck 20 carrying the raw tires T to be vulcanized moves to the standby line 238 and stops when the preceding truck 20 is placed sideways on the corresponding vulcanization station 230. Thereafter, when the bogie 20 is dropped on the standby line 238 at a predetermined timing, the bogie 20 moves laterally to the stop line 234, and after removing the bogie 20 already laid, the new raw tire T is mounted from the standby line 238. Trolley 2
0 is moved to be laid sideways on the vulcanizer 232.

The operation of the present embodiment will be described below. In the molding area 22 of the tire molding system 10, a predetermined process is performed on each of the stages provided in the area to mold the raw tire T. At this time, the AGV 100 moves between the stages to carry the raw tire T to be formed.

The raw tire T molded in the molding area 22
Are mounted on the trolley 20 in a two-tiered manner, and the trolley 20 is carried by the AGV 100 to be taken out of the molding area 22. When the AGV 100 supports the bogie 20 on which the raw tire T is mounted,
Information such as the size of a tire mounted on the carriage 20 and a running program are input. When the information on the raw tire T is written into the ID tag 210 provided on the bogie 20, the AGV 100 starts running based on the input running program.

In the tire molding system 10, the green tire T molded in the molding area 22 is placed in the vulcanized area 24.
The mold release liquid is applied to the inner peripheral surface before being transported. For this purpose, the AGV 100 includes the raw tire T in the molding area 22.
, A traveling program for transporting to the painting area 26 is input.

The AGV 100 on which the bogie 20 on which the raw tire T is mounted is placed on the approach line 2 from the molding area 22.
6A, moves to the coating area 26, and
2 to a predetermined position below. This painting area 26
The stop position of the AGV 100 at the center of the hollow portion of the raw tire T laterally stacked on the carriage 20 (point O) is the coating device 72.
The shaft 84 is substantially directly below the shaft 84. AGV100
Outputs the information such as the tire size of the raw tire T recorded on the ID tag 210 of the cart 20 to the coating device 72 when stopped at a predetermined position in the coating area 26.

On the other hand, when the AGV 100 that has transported the raw tire T stops, the coating device 72 drives the lifting / lowering motor 80 to lower the shaft 84 and the arm 97 together, and the photoelectric sensor 99A causes the truck 20 to move to the carriage 20. The position of the mounted raw tire T is detected. That is, when the shaft 84 is lowered by the driving of the elevating motor 80, the reflecting cylinder 95 is lowered together with the rotating body 94 and the camera 90 provided at the lower end of the shaft 84. At the same time, the photoelectric sensor 99A at the lower end of the arm 97 facing the outer peripheral surface of the raw tire T also descends.

Thus, when the reflecting cylinder 95 enters the hollow portion of the raw tire T, the light of the photoelectric sensor 99A is blocked by the raw tire T. The coating device 72 determines the position (for example, the height from the floor) where the raw tire T is provided, that is, the application region of the release liquid along the vertical direction from the detection result of the photoelectric sensor 99A. .

In the coating device 72, the photoelectric sensor 9
When it is detected from the detection result of 9A that the camera 90 has entered the hollow portion of the raw tire T and is in a state of facing the inner peripheral surface of the raw tire T, the rotation motor 88 is driven to drive the camera 9.
By rotating 0, the seam of the bead of the raw tire T is detected.

Further, when the communication device 226 receives the information about the raw tire T such as the tire size output from the AGV 100 by the communication head 226, the coating device 72 releases the inner peripheral surface of each raw tire T with a predetermined coating thickness. Calculate the amount of release liquid required to apply the liquid.

When the coating conditions such as the position of the raw tire T mounted on the carriage 20 (application region of the release liquid), the seam of the cord, and the required amount of the release liquid are determined, the application device 72
First, the rotation motor 88 is driven to rotate the bracket 88A so that the camera 90 faces the seam of the cord of the raw tire T mounted on the upper support frame 68 of the carriage 20. Position between the seams of the cord. Thereafter, the elevation motor 80 is driven while the height of the mask plate 98 is adjusted by the elevation cylinder 96 to lower the shaft 84. At this time, the arm 97
The shaft 84 is lowered while detecting the position of the raw tire T by the photoelectric sensor 99B at the lower end of the motor. When the photoelectric sensor 99B detects the raw tire T, the rotation drive motor 9
The rotary member 94 is driven to rotate by 2 and a release liquid is supplied.

The release liquid supplied to the rotator 94 is rotated by the rotator 94 at a high speed, and the centrifugal force causes the nozzle 9 to rotate.
4A, and is applied to the inner peripheral surface of the raw tire T.

The coating device 72 is thus mounted on the carriage 20
A release liquid is applied to each of the inner peripheral surfaces of the raw tires T stacked horizontally in two stages. At this time, since the coating device 72 can apply the release liquid while the raw tire T is mounted on the carriage 20, the work table is applied to apply the release liquid to the inner peripheral surface of the raw tire T. It is not necessary to change over the application, and the application of the release liquid can be performed automatically. The coating device 7
In No. 2, since the amount of the release liquid applied to each raw tire T is calculated based on the tire size of the raw tire T input via the AGV 100, it is possible to apply an appropriate amount of the release liquid. .

Since the bogie 20 has two stages of raw tires T before and after the AGV 100 in the advancing direction, one bogie 20 has two raw tires T on the front and rear sides in the advancing direction. A release liquid is applied to each of them.

When the application of the release liquid to the inner peripheral surface of the raw tire T mounted on the carriage 20 is completed, the AGV 100 is transmitted to the AGV 100 via the communication head 226 provided in the coating area 26. Is output, and information such as the time during which the mold release liquid is applied to the raw tire T (the application end time) is input. In the AGV 100, information such as the fact that the raw tire T mounted on the trolley 20 has completed the application of the release liquid and the ending time of the application are added to the ID tag 210 of the trolley 20 and newly added. The vehicle starts traveling based on the inputted traveling program.

In the tire forming system 10, the raw tire T, for which the release liquid has been completed, is kept for a predetermined time (for example, about 80 minutes).
After the mold release liquid applied to the raw tire T is allowed to air dry by leaving it to stand, etc.
Vulcanization is performed, and for this, the raw tire T
Is transported from the coating area 26 to the vulcanization area 24, and after a predetermined time elapses, is laterally or obliquely moved to the vulcanizer 232 of the vulcanization stage 230 to be laid sideways, or is stored in the vehicle. After being transported to the yard 30 and temporarily stored, it is transported to the vulcanization area 24. Here, as an example, a description will be given in such a manner that the material is once stored in the carriage storage yard 30 and then transported to the vulcanization area 24.

When the application of the release liquid to the raw tire T mounted on the carriage 20 is completed, the AGV 100 starts running based on the input running program, and the exit line 26
B, enters the forming area 22 again, passes through the exit line 22B, and the carriage storage yard 30 of the storage area 28.
Head to. In addition, the vulcanization area 2 directly from the molding area 22

When the AGV 100 moves to a predetermined position on the storage line 36, it lowers the bar member 104, lowers the bogie 20, and then travels on the storage line 36 toward the entry route exit 38B to store the bogie. When the yard 30 leaves, it moves to the waiting yard 32 and stops at a predetermined position.

On the other hand, when the retrieval of the bogie 20 stopped on the storage line 36 is supported, the AGV 100 enters the storage line 36 where the corresponding bogie 20 is stopped from the exit route entrance 38C, and Move down. Thereafter, when the cart 20 is lifted by raising the bar member 104, the bar 20 moves laterally from the storage line 36 to the entry / exit line 34,
The vehicle travels toward the exit route 38D of the entry / exit line 34.

[0114] As described above, the trolley 20 is thin and enters the lower part of the trolley 20 supported by the casters 52. When the trolley 20 is not mounted, the trolley 20 travels on the storage line 36 where the trolley 20 is stopped. Also, the AGV 100 is
Is placed on the loading / unloading line 3 where the carriage 20 is not stopped.
Run 4 Thus, the AGV 100 can be effectively and smoothly run in a narrow space.

The host computer 220 manages the elapsed time from the application of the mold release liquid of the raw tire T mounted on the carriage 20 stopped in the carriage storage yard 30. When the time has elapsed, the bogie 20 on which the corresponding raw tire T is mounted is moved to the vulcanization area 24 by the AGV 100 so that the raw tire T mounted on the bogie 20 is vulcanized.

The AGV 100 carrying the bogie 20 carrying the raw tires T to be vulcanized enters the vulcanization area 24 from the entry line 24A after passing through the exit route 38D, and is designated in the vulcanization area 24. Vulcanization stage 230
