The tire gripping device 103 is vertically movable and swingable between three positions d, e, and f shown in FIGS. 1 and 2, and grips the tire T at the d position. Ascends, moves to the position e, discharges the tire onto the conveyor C, then moves to the position f, receives the unvulcanized tire, moves to the position d, and moves the unvulcanized tire to the lower mold M2. It is designed to be installed on top.
[0021]
Next, the operation of the tire vulcanizing equipment shown in FIGS. 1 and 2 will be specifically described.
(1) In the vulcanization stations 1a-1 and 1a-2, each tire mold M vulcanizes a tire. The vulcanized tire mold M is received by the first mold carrier 3 from the tire mold M, conveyed to the mold opening / closing station 1b, and delivered to the mold opening / closing station 1b, where the tire mold M and the mold are received. by combining the mold opening and closing device 100, and then open the upper mold portion M ₁ of the tire mold M by the mold opening and closing device 100, thereby traverse the lower mold portion M _2. The vulcanized tire is taken out by the tire gripping device 103 attached to the mold opening / closing device 100 at the position moved laterally, and the vulcanized tire is placed adjacent to the mold opening / closing device 100 and a vulcanized tire unloading conveyor. Take out onto C.
[0022]
After unloading the vulcanized tire, the tire gripping device 103 receives the unvulcanized tire to be vulcanized next, which is sorted and sent out from the unvulcanized tire supply device B, and unloads the vulcanized tire. carries the unvulcanized tire in a mold M, performs shaping of the tire (shaping), traverses the the lower mold portion M ₂ and the shaped green tire to the appropriate time after shaping, or the way It was followed by a die opening and closing device 100 lowers the upper mold portion M _1, by closing the tire mold M, introduced inside the heating pressurizing medium in the tire, by sealing this tire vulcanizing process to go into.
[0023]
Then, the bond between the tire mold M that has started vulcanization and the mold opening / closing device 100 is released, and the tire mold M is mounted on the first mold carrier 3 again, and the vulcanization stations 1a-1, 1a- Return to 2.
(2) If it is necessary to replace the mold or replace the bladder due to a change in the specification of the vulcanized tire, carry out the vulcanized tire according to the above procedure and then carry in the unvulcanized tire. Without closing the tire mold M, the tire mold M is transported to the mold exchanging station 7 by the second mold transport cart 5.
[0024]
At that time, in the tire vulcanizing equipment shown in FIG. 1, after the empty tire mold M is returned to the original vulcanization stations 1a-1 and 1a-2 by the first mold transport cart 3, the first mold transport is performed. The truck 3 is engaged in processing of the next vulcanized tire. On the other hand, the returned empty tire mold M is picked up by the second mold carrier 5 and transported to the mold changing station 7.
[0025]
In the tire vulcanizing equipment shown in FIG. 2, an empty tire die M is transported by the first die transporting truck 3 to the die transfer position at the end of the vulcanizing stations 1a-1 and 1a-2, and the second die is transported. After the delivery to the mold carrier 8, the first mold carrier 3 is engaged in processing the next vulcanized tire. On the other hand, the empty tire mold M delivered to the second mold carrier 8 is transported to the mold changing station 10 by the second mold carrier 8.
[0026]
If the mold exchanging station 7 of the tire vulcanizing equipment shown in FIG. 1 and the mold exchanging station 10 of the tire vulcanizing equipment shown in FIG. The mold M or the bladder can be replaced, and the preheating after the tire mold M or the bladder has been replaced can be performed. If these mold changing stations are equipped with a heating and pressurizing medium introduction facility, test vulcanization after preheating can also be performed.
[0027]
The tire vulcanizing equipment shown in FIG. 1 is effective when the frequency of exchanging the tire dies M is high or when the vulcanization time of each of the tire dies M is short and the first die carrier 3 is busy. In addition, since the second mold carrier 4 travels between adjacent vulcanization equipments, it can be used for two vulcanization equipments. In the illustrated example, one second mold carrier is used for 10 tire molds M in combination.
[0028]
The tire vulcanizing equipment shown in FIG. 2 is effective when the frequency of exchanging the tire mold M is low. In the example shown in the figure, one second mold carrier 8 is used in combination with 44 tire molds M. You.
[0029]
