Abstract
A tire vulcanizing method reduces consumption energy and increases productivity of vulcanization. This method involves supplying an inert gas to an internal space of the tire via a supply pipe, discharging the gas from the internal space via a return pipe, and supplying the gas from the return pipe to the supply pipe by a rotation type circulation device. A heating device heats the circulated gas. An internal outlet gas temperature sensor detects a temperature of the gas in the return pipe. A controller decreases a rotating speed of the circulation device when the return pipe gas temperature is a rotating speed decrease temperature or more.
Claims14
A method, comprising:
- supplying an inert gas to an internal space of a tire provided in a tire vulcanizer via a supply pipe
- and discharging the inert gas from the internal space of the tire via a return pipe by circulating
- the inert gas received from the return pipe toward the supply pipe with a rotation type circulation device;
- heating the inert gas supplied to the internal space via the supply pipe with a heating device;
- detecting a temperature of the inert gas flowing through the return pipe with an outlet gas temperature sensor;
- and
- operating the rotation type circulation device at a first rotation speed, when the outlet gas temperature sensor detects a temperature below a temperature T1, and operating the rotation type circulation device at a second rotation speed, when the outlet gas temperature sensor detects a temperature at or above the temperature T1, the first rotation speed being greater than the second rotation speed.
A tire vulcanizer, comprising:
- an internal space located inside of a tire when the tire is present in the tire vulcanizer;
- a supply pipe that is an inlet to the internal space;
- a return pipe that is an outlet from the internal space;
- a rotation type circulation device provided between the return pipe and the supply pipe that, in operation, rotates to move the inert gas received from the return pipe toward the supply pipe to circulate the inert gas into the internal space via the supply pipe and out of the internal space via the return pipe;
- a heating device provided between the return pipe and the supply pipe that, in operation, heats the inert gas that is supplied to the internal space via the supply pipe;
- an outlet gas temperature sensor that, in operation, detects a temperature of the inert gas flowing through the return pipe;
- and
- a controller that operates the rotation type circulation device at a first rotation speed, when the outlet gas temperature sensor detects a temperature below a temperature T1, and operates the rotation type circulation device at a second rotation speed, when the outlet gas temperature sensor detects a temperature at or above the temperature T1, the first rotation speed being greater than the second rotation speed.
