Heating fluid medium passing roller device

Abstract

In a heating fluid medium passing roller device for heat-treating a object to be processed in contact with the surface of a roller 1, heat exchanger devices 5a, 5b are arranged on a circulating heating fluid medium path, and the heating fluid medium heat-exchanged in the heat exchanger device is passed through the roller 1 having a jacked chamber 1b sealed with a gas-liquid two phase heating medium within its wall to keep the roller 1 at a predetermined temperature. Further, the heating fluid medium passing roller device includes a temperature sensor 13 for detecting the temperature of the heating fluid medium to be supplied into the roller 1 and a temperature sensor 14 for detecting the temperature of the heating fluid medium exhausted from the roller 1. The flow rate of the heating fluid medium to be supplied into the roller is adjusted so that the difference between the temperatures detected by the temperature sensors 13 and 14 is constant. Thus, the heating fluid medium passing roller device can be operated with optimum energy saving in quick response to a change in the surface temperature of the roller.

Claims

1. A heating fluid medium passing roller device comprising: a roller having a plurality of jackets sealed with a gas-liquid two-phase heating medium in wall thereof and a heating fluid medium flow path for passing a circulating heating fluid medium through the roller, a heating fluid medium temperature adjuster for adjusting the temperature of the heating fluid medium, and a heating fluid medium flow-rate adjuster for adjusting the flow-rate of the heating fluid medium to be supplied into the heating fluid medium flow path of the roller, wherein the surface temperature of the roller is kept at a prescribed temperature by the heating fluid medium flowing through the heating fluid medium flow path, which is adjusted by the heating fluid medium temperature adjuster and the heating fluid medium flow-rate adjuster.

2. The heating fluid medium passing roller device according to claim 1, wherein the heating fluid medium flow-rate adjuster has a pump for circulating the heating fluid medium, andthe flow-rate of the heating fluid medium to be supplied into the roller by the pump is adjusted on the basis of a difference between the surface temperature of the roller and the temperature of the heating fluid medium supplied to the heating fluid medium flow path of the roller.

3. The heating fluid medium passing roller device according to claim 1, wherein the heating fluid medium flow-rate adjuster has a pump for circulating the heating fluid medium, andthe flow-rate of the heating fluid medium to be supplied into the roller by the pump is adjusted on the basis of a difference between the temperature of the heating fluid medium supplied to the heating fluid medium flow path of the roller and the temperature of the heating fluid medium exhausted from the heating fluid medium flow path.

4. The heating fluid medium passing roller according to claim 1, wherein a circulating path of the heating fluid medium includes a flow path on which a flow-rate adjusting valve communicating with the heating fluid medium flow path of the roller is arranged, and a flow path on which a flow-rate adjusting valve bypassing the roller is arranged, andthe heating fluid medium flow-rate adjuster adjusts the flow-rate of the heating fluid medium to be supplied into the roller by each of the flow-rate adjusting valves on the basis of a difference between the surface temperature of the roller and the temperature of the heating fluid medium to be supplied to the heating fluid medium flow path of the roller.
