APPARATUS FOR BUNDLING HOT COILS

Japanese Patent JP3955136

B

PROBLEM TO BE SOLVED: To prevent a hot coil outer periphery after bundling from loosening or a band from being cut, and to reduce fastening time by measuring a temperature of the hot coil outer periphery by a thermometer provided on a bundling machine before tightly attaching the band to the hot coil outer periphery and by fastening and tightening the band with proper fastening force based on the temperature information.
SOLUTION: An excessive band is brought back by reversely rotating an air motor 2, and a band is wound around a coil C when a bundling head 1 comes into contact with the coil C. At this time, the bundling head 1 lowers, and before it comes into contact with the coil C, measuring of a temperature of a coil outer periphery is started by a thermometer 2. Based on the correct coil outer periphery temperature information, time from a point when the band is wound around the coil outer periphery until fastening is completed is estimated, and breaking force and elastic limit of the band is obtained from a band surface temperature at the time of fastening completion to obtain fastening force which may cause no breakage. Thereafter transmission of the air motor 2 is changed over to a low speed/high torque side, and the band is fastened by the bundling head 1 for tightening.
