A heating unit includes a plurality of radiant heaters, a plurality of brackets on which the radiant heaters are mounted in a row, and a frame on which the brackets are mounted in a parallel arrangement and thereby the radiant heaters are mounted in a grid configuration, wherein each of the radiant heaters includes: a support plate substantially having a rectangular shape; a pair of connection terminals substantially perpendicularly extending, while having a space therebetween, from one surface of the support plate; and a strip-shaped heater element arranged between the pair of connection terminals and covering the one surface of the support plate, and wherein the connection terminals have connection portions projecting from the other surface of the support plated, and each of the brackets has a terminal hole into which the connection portion is inserted.

Heating unit and resin sheet heating apparatus

A heating apparatus includes a plurality of heating means that heat a heated object, a temperature measuring means that measures temperatures of some of the plurality of heating means, a heated object information storing means that stores, in a coordinate manner, heated object identification names, target heating temperatures at the heating means, and sets of heating ratios respectively assigned to the heating means, a heating information storage means that defines a relationship between temperatures during heating of the heating means up to the target heating temperatures and heating intensities at the temperatures, a heated object identification name obtaining means that obtains one of the heated object identification names, a heated object information reading-out means that reads out one of the target heating temperatures and one of the sets of heating ratios respectively assigned to the plurality of heating means, corresponding to the heated object identification name from the heated object information storage means, a heating information reading-out means that reads out one of the heating intensities corresponding to the temperature measured by the temperature measuring means from the heating information storage means, and a heat control means that controls each of the plurality of heating means so that the target heating temperature is achieved.

Heating apparatus and heating method

A heating system includes a plurality of radiant heaters, a power source supplying electricity to the radiant heaters, and a transformer provided between the radiant heaters and the power source, wherein each of the radiant heaters includes a support plate substantially having a rectangular shape, a pair of connection terminals substantially perpendicularly extending, while having a space therebetween, from one surface of the support plate, and a strip-shaped heater element arranged between the pair of connection terminals and covering the one surface of the support plate, wherein voltage E between the pair of connection terminals is adjusted by the transformer so as to satisfy an inequality of 25 V&#x2266;E&#x2266;35 V, wherein a width W of the strip-shaped heater element is set so as to satisfy an inequality of 8.5 mm&#x2266;W&#x2266;11.7 mm, and a thickness t thereof is set so as to satisfy an inequality of 0.05 mm&#x2266;t&#x2266;0.8 mm, and wherein the radiant heaters are connected to the transformer in a 3-phase and 4-wire configuration, a neutral line is connected to ones of the connection terminals, and one of a U-phase, V-phase, and W-phase of a secondary side of the transformer is connected to the others of the connection terminals.
