TIRE VULCANIZER AND TIRE VULCANIZING METHOD
First Claim
1. A tire vulcanizing apparatus comprising:
- a mold for removably accommodating a raw tire;
a medium path, connected to an internal space of the raw tire accommodated in the mold, for passing a heating and pressurizing medium of a gas or air for vulcanizing and molding the raw tire;
a pressure sensor, provided in the medium path, for measuring a pressure of the heating and pressurizing medium;
a pressure control valve, provided in the medium path, for controlling the pressure of the heating and pressurizing medium passing through the medium path on the basis of a signal from the pressure sensor;
a temperature sensor, provided in the medium path, for measuring a temperature of the heating and pressurizing medium; and
a heating unit, provided in the medium path, for controlling the temperature of the heating and pressurizing medium passing through the medium path on the basis of a signal from the temperature sensor, whereinthe pressure control valve and the heating unit control the pressure and temperature of the heating and pressurizing medium supplied from the medium path to the internal space of the raw tire respectively and independently.

Abstract
A tire vulcanizing apparatus and a tire vulcanizing method, by which the pressure and temperature of a heating and pressurizing medium to be supplied to the internal space of a raw tire can be controlled without the condition of pressure being affected by the condition of temperature. The tire vulcanizing apparatus has: a medium path, connected to an internal space of a raw tire, for passing a heating and pressurizing medium; a pressure sensor, provided in the medium path, for measuring a pressure of the heating and pressurizing medium; a pressure control valve for controlling a pressure of the heating and pressurizing medium passing through the medium path on the basis of a signal from the pressure sensor; a temperature sensor, provided in the medium path, for measuring a temperature of the heating and pressurizing medium; and a heating unit for controlling the temperature of the heating and pressurizing medium passing through the medium path on the basis of a signal from the temperature sensor, wherein the pressure control valve and the heating unit control the pressure and temperature of the heating and pressurizing medium supplied from the medium path to the internal space of the raw tire respectively and independently.

8. A tire vulcanizing method, comprising:
-
a pressure measurement step of measuring a pressure of a heating and pressurizing medium by means of a pressure sensor provided in a medium path for passing a heating and pressurizing medium of a gas or air for vulcanizing and molding a raw tire, the medium path being connected to an internal space of the raw tire; a pressure control step of controlling the pressure of the heating and pressurizing medium on the basis of a signal from the pressure sensor by means of a pressure control valve provided in the medium path; a temperature measurement step of measuring a temperature of the heating and pressurizing medium by means of a temperature sensor provided in the medium path; and a temperature control step of controlling the temperature of the heating and pressurizing medium by means of a heating unit provided in the medium path on the basis of a signal from the temperature sensor, wherein the pressure and temperature of the heating and pressurizing medium supplied from the medium path to the internal space of the raw tire are controlled respectively and independently in the pressure control step and the temperature control step. - View Dependent Claims (9, 10)
