The operation of the split mold device for a tire vulcanizer shown in FIGS. 20 to 22 applied to the tire vulcanizing equipment shown in FIGS. 18 and 19 is as follows. 18 to 20, and FIG.
The vulcanization of the tires in the tire vulcanizing mold Ma, which was on the mold table 5a of the vulcanizing station 1a, is completed, and the mold transport vehicle 3
a, the mold opening and closing device 6 of the mold opening and closing station 2a.
3A shows a state where the transfer has been completed.

At this time, a set of claws 134a and 138a
In the engaged state, the set of claws 139a and 146b is in a passable state. From this state, first, the cylinder 6d is operated, the arm 6c is lowered, and the cover plate 130 and the bolster plate 140 are moved by the attaching / detaching device 141.
And the heating and pressurizing medium passages 120c,
20d is connected to a die outside piping (not shown) via quick couplers 128 and 129.

Next, a switching valve (not shown) is operated,

The upper sidewall mold 213 is released, and the center post 22 is released while applying a vacuum to the bladder B through the passage 223a.
3 is raised, and the bladder B is pulled out from the inside of the tire T.

Next, the vulcanized tire T is suspended outside the tire vulcanizing mold Ma by the operation of the unloader 7a, and the unvulcanized tire T to be vulcanized next is vulcanized by the operation of the loader 8a. Suspended in the working mold Ma. While supplying steam for shaping into the bladder B through the passage 223a,
When the bladder B is inserted into the suspended unvulcanized tire T by lowering the center post 223, the loader 8a
Releases the grip on the tire T and moves to the standby position. After moving to a position where it does not interfere with the upper heating plate 214, the upper heating plate 214 is lowered by the operation of the cylinder 6d.
After the shaping and the tire vulcanizing mold closing process are performed by a known procedure, and the upper hot plate 214 comes into contact with the segment 210, the cylinder 6f is also operated, and the lower hot plate 214 is 203 is pressed down, and the tread mold 209 is reduced in diameter, and the tire vulcanizing mold Ma is closed.

At this time, the claws 210c and 214a and 203a and 210b are simultaneously engaged, so that after the tire vulcanizing mold Ma is closed, the heating and pressurizing medium is inserted into the tire T through the bladder B. Is introduced, and even if vulcanization is started, the force for opening the mold by the pressure of the heating and pressurizing medium is applied through the segment 210 by the engagement of the claws 210c and 214a and the 203a and 210b. Offset, the mold does not open.

After the tire vulcanization is started, the connection between the tire vulcanizing mold Ma and the mold opening / closing device 6a is released in the reverse procedure. At this time, the passages 223a and 223
Since the check valve is incorporated in the lower end of 1b, the tire internal pressure is maintained. Next, the tire vulcanizing mold Ma is conveyed by the mold conveying cart 3a onto the mold stand 5a of the vulcanizing station 1a, and vulcanization is continued, and the mold conveying cart 3
Next, a receives the vulcanized tire vulcanizing mold and transports it to the mold opening / closing station 2a.

When replacing the bladder B or the like, the mold is closed without suspending the tire T to be vulcanized next (in this case, of course, the heating and pressurizing medium is not introduced).
While being conveyed to the mold exchanging station 11 and the bladder B or the like is exchanged, another tire vulcanizing mold is taken in and out of the bladder B at the mold conveying vehicle 3a and the mold opening / closing station 6a. After the replacement of the tires and the like is completed, the tires are transported to the mold opening / closing station and the tires to be vulcanized are inserted.

SUMMARY OF THE INVENTION The split mold device for a tire vulcanizer shown in FIGS.
Has the following problems. (A) When the mold is opened, the completed tire is taken out and the unvulcanized tire is loaded, it is necessary to extend the bladder B, and therefore the center post is extended. (B) The mold opening and closing stations 2a and 2b shown in FIGS. 18 and 19 are stationary molds, and when the mold is opened, the upper mold waits above the lower mold. In order for the unloader 7a for removing the completed tire and the loader 8a for supplying the unvulcanized tire to enter between the upper mold and the lower mold, the mold opening / closing station 2a,
It is necessary to increase the stroke of the cylinder 6d of 2b to increase the distance between the upper and lower molds.

For this reason, although the heights of the upper portions of the vulcanizing stations 1a and 1b can be reduced, the height of the mold opening / closing stations 2a and 2b is increased, and it is necessary to reduce the height. (C) When supplying unvulcanized tires using the upper space of the vulcanization stations 1a and 1b, the tire supply device needs to enter at a higher position, and the die The problem of the height of the opening and closing stations 2a, 2b also arises.

(1) A tire vulcanization mold M whose vulcanization has been completed from a vulcanization station in which a plurality of tire vulcanization molds M being vulcanized are arranged.
Is transported to the fixed position of the mold opening / closing station by the mold transport cart D. At this time, the mold opening / closing devices 306 to 312
Is waiting to descend to a position where it does not hinder the progress of the mold. On the other hand, the gripping device 3 of the tire handling device 313
13b stands by above the tire discharge position without gripping the vulcanized tire or the unvulcanized tire (see FIGS. 4 and 5). (2) After the mold stops at the fixed position, the mold opening / closing device 306
３312 descends to connect with the mold (FIG. 6,
(See FIG. 7). (3) The mold opening / closing devices 306 to 312 are raised, and the tire vulcanizing mold (split mold) M is also opened, so that the upper mold is lower than the tire and bladder operating mechanism left on the lower mold. It reaches a slightly higher position and stops (see FIG. 8). (4) The mold opening / closing devices 306 to 312 move laterally and stop. After stopping, the bladder in the tire extends,
While peeling from the tire inner surface is performed, the tire handling device 313 starts operating for tire reception (see FIG. 9). (5) Gripping device 313 of tire handling device 313
b descends and the upper bead portion of the tire is gripped. At the same time, the mold opening / closing devices 306 to 312 pull in all or a part of the split mold once opened at the stop position, the lowermost position of the upper mold is raised, and a preparation operation for the next lateral movement is performed (FIG. 10). reference). (6) Gripping device 313 of tire handling device 313
When b rises by gripping the tire and rises to a predetermined height, it moves to the tire discharging position and then the tire is discharged (see FIG. 11). After discharging, it moves to the unvulcanized tire receiving position and receives the unvulcanized tire. (7) After receiving the unvulcanized tire, the unvulcanized tire is moved to a position above the lower mold, and subsequently descends, and the lower bead portion of the unvulcanized tire engages with the bead ring mold of the lower mold (FIG. 12, Figure 1
3). (8) Next, the pressure medium is supplied into the bladder, the bladder is inserted into the unvulcanized tire, and the gripping device 313b of the tire handling device 313 releases the grip of the unvulcanized tire at an appropriate time, After ascending, it returns to the tire discharge position and waits (see FIG. 14). (9) The waiting mold opening / closing devices 306 to 312 move laterally, stop so that the upper mold coincides with the center of the lower mold, and then descend to start the mold closing operation ( See FIG. 15). (10) After the mold closing is completed, the mold opening / closing devices 306 to 312
The connection between the mold and the mold is released, and the mold opening / closing devices 306 to 31 are opened.
2 moves to the lower position where it does not hinder the movement of the mold,
It waits until the next mold enters (see FIGS. 16 and 17). (11) The mold is returned to the original position of the vulcanization station by the transport device. Hereinafter, the same operation is repeated, and production is performed. (12) The discharged tire is sent toward the main conveyor by a roller conveyor or the like prepared at an appropriate position above the vulcanizing station, and the next unvulcanized tire to be supplied is selected from the prepared tires. Then, it is supplied to the unvulcanized tire supply position.
