As shown in FIG. 2, the upper electromagnetic coil 2
By lowering the bolster plate 12 to the position shown by the solid line, it comes into contact with the upper surface of the top plate 8, and the side electromagnetic coil 3 operates by extending the cylinder 19 at the lower position of the bolster plate 12, thereby causing the outer circumference of the outer ring 7 to move. Touch the surface. Also, the lower electromagnetic coil 4
Is brought into contact with the lower surface of the bottom plate 5 by extending the cylinder 22 as indicated by a chain line.

When an alternating current is supplied from an AC power supply (not shown) to the electromagnetic coils 2, 3 and 4 in contact with each other, an induced current induced on the basis of the magnetic field generated by these coils 2, 3 and 4 Thereby, the mold assembly M is heated. That is, for example, the pair of upper and lower side electromagnetic coils 3 shown in FIG. 5 generates an alternating magnetic field as exemplified by the arrow, and the side of the mold assembly M is heated by the induced current based on this magnetic field. You. The upper electromagnetic coil 2 and the lower electromagnetic coil 4 also generate a similar alternating magnetic field in a pair, and heat the upper and lower portions of the mold assembly M, respectively.

Thus, according to the heating device of this embodiment, the mold assembly M is used without using steam.
The entire mold assembly M can be heated without performing any additional processing on the mold assembly M.

Next, the operation of the tire vulcanizing equipment according to the present invention will be described. (1) When the tire vulcanization in the tire mold assembly of the vulcanizing station C21 is almost completed, the second tire mold transport vehicle T2c moves to the stop position T21 in front of the vulcanizing station C21 and stops. I do. (2) Then, the connection of the internal pressure supply device (not shown) at the vulcanizing station C21 is released, while the mold take-up arm (not shown) on the table of the second tire mold transport vehicle T2c is connected to the vulcanizing station C21. And connected to the lower part of the tire mold assembly M21. (3) The mold take-up arm is retracted. As a result, the tire mold assembly M21 is
The vehicle slides on the group of 21 guide rollers Cf, then slides on the group of guide rollers on the second tire mold transport vehicle T2c, and stops when it reaches a predetermined position. (4) When the tire mold assembly M21 stops, the lower part of the tire mold assembly M21 is moved to the second tire mold transport vehicle T.
2c. On the other hand, the second tire mold carrier T2
c moves to the stop position T20 in front of the mold opening / closing device OP and stops. (5) After the stop, the mold take-up arm of the second tire mold carrier T2c is extended toward the center of the mold opening / closing device OP. Then, the mold take-up arm is released from the connection with the lower portion of the tire mold assembly M21, and is pulled in the direction of the second tire mold carrier T2c. Then the second
The tire mold carrier T2c moves to the stop position (T21, T22 or T23) in front of the vulcanization station where vulcanization is to be finished next, and stands by. (6) The upper movable plate OPc of the mold opening / closing device OP.
Is waiting at a position slightly higher than the tire mold assembly M21 so as not to hinder the movement of the moving tire mold assembly M21. (7) When the tire mold assembly M21 stops, the lower portion of the tire mold assembly M21 is fixed, while the upper movable plate OPc descends and is connected to the upper portion of the tire mold assembly M21. (8) Next, the mold opening operation is performed, and the upper mold starts to open. When the upper movable plate OPc continues to rise, the upper mold is completely opened and reaches the uppermost position. The vulcanized tire is left on the lower mold, and a bladder assembly (not shown) provided at the center of the tire mold assembly M21 is provided at the lower center of the mold opening / closing device OP. The bladder is peeled from the inside of the tire by operating the bladder driving device (not shown). (9) At an appropriate time, the unloader OPh enters and descends, the upper bead of the vulcanized tire on the lower mold is gripped, and the vulcanized tire is lifted and carried out. The transported vulcanized tire is transported to the next step by a transport conveyor (not shown) or the like. (10) Also, at an appropriate time, the loader OPg enters and descends while grasping the unvulcanized tire, and the unvulcanized tire is installed on the lower mold. Thereafter, the bladder driving device operates, A bladder is inserted into the unvulcanized tire. (11) Further, at an appropriate time, the loader OPg releases the grip of the unvulcanized tire, rises and retreats, then lowers the upper movable plate OPc, and moves the opened upper mold to the closed position. I do. (12) After the closing of the mold, the connection between the upper movable plate OPc and the upper mold is released, and the upper movable plate OPc rises to a height that allows the tire mold assembly M21 to pass through, while the mold assembly is moved. The fixation of the lower part of M21 is released. While working with the mold opening / closing device OP, the first tire mold carrier Tlc is used.
Are waiting at the exit side stop position T10 (heating station K) of the mold opening / closing device OP. (13) The mold take-up arm is extended from the first tire mold carrier Tlc, and is connected to the lower part of the tire mold assembly M21. Next, the arm is retracted, and the tire mold assembly M21 is guided by the guide roller O of the mold opening / closing device OP.
Sliding on the Pf group, and further, the first tire mold carrier Tl
c) Transfers to the group of guide rollers Tlb on c and slides. Then, when it reaches a predetermined position in the heating station K, it stops. (14) The lower part of the tire mold assembly M21 carried into the heating station K is the first tire mold carrier T
After being fixed at 1c, it is heated by the electromagnetic heating device provided at the heating station K. (15) The heated tire mold assembly M21 is
The tire mold carrier Tlc moves along the vulcanizing station and stops. The stop position is the stop in front of the tire mold assembly M11 that is arranged alongside the tire mold assembly M21 that has been moved in the explanations of the above operations (1), (2) and (3). Position Tl1. After the tire mold assembly M21 has been picked up by the second tire mold carrier T2c, the vulcanizing station C that has become empty thereafter.
The vulcanized tire mold assembly M11 is transferred from 21 to the adjacent vulcanization station C11. Therefore, the vulcanization station C1 on the first tire mold carrier Tlc side is used.
1 is empty. That is, the vulcanizing station C11 is ready to receive the tire mold assembly M21 heated at the heating station K. (16) When the first tire mold carrier Tlc stops at the stop position T11 in front of the vulcanizing station C11, the fixing of the tire mold assembly M21 is released, and then the first tire mold carrier Tlc. Arm is extended. As a result, the tire mold assembly M21 slides on the guide rollers T1b on the trolley, then moves on to the guide rollers Cf of the vulcanizing station C11, slides, and stops. (17) After stopping, the arm is retracted in the direction of the carriage, and the carriage moves to the mold opening / closing device position, stops and stands by. On the other hand, the internal pressure supply device and the external pressure supply device are connected to the heat-treated tire mold assembly M21 stopped at the vulcanization station, and a heating / pressurizing medium is supplied to continue vulcanization of the tire.

When producing a tire, as shown in the above description of the operation, the tire mold assembly M after vulcanization is loaded from the exit side of the vulcanization station (C11 to C23) to the second tire mold carrier. At T2c, it is transported to the mold opening / closing device, and after performing a predetermined operation there, it is returned to the entrance side of the vulcanization station by the first tire mold transport device to continue vulcanization.

In the tire vulcanizing equipment according to the above-described embodiment, a mold assembly M having a lower mold 9, an upper mold 10, and a tread mold portion 11, which are split molds, is used.
Of course, it is also possible to use a so-called two-piece mold in this vulcanization facility.
