Abstract:
1. A carrier positioning method that transports a plurality of carriers, on which pieces of work are respectively mounted, by a transport conveyor into a heating furnace and that positions the plurality of carriers, the carrier positioning method comprising: a transport process of transporting the plurality of carriers by the transport conveyor into the heating furnace; a first advance process in which a control device advances a comb-shaped carrier stopper, which has a plurality of protrusions used for positioning the carriers, toward the carriers positioned in series on the transport conveyor; a positioning process of positioning the carriers at a time at predetermined intervals in a transport direction in which the carriers are transported in such a manner that the carriers positioned in series are moved by the transport conveyor in the transport direction to engage engagement portions, provided respectively for the carriers, with the protrusions of the carrier stopper; a second advance process in which the control device advances the carrier stopper at insertion holes positioned on the carriers so as to insert distal ends of the respective protrusions of the carrier stopper into the insertion holes of the engagement portions, wherein the insertion holes are provided so as to allow the distal ends of the protrusions to be inserted when the carriers are properly positioned; a determination process in which the control device determines, on the basis of a total moved distance of the carrier stopper toward the carriers during the first advance process and second advance process, whether the carriers in series are properly positioned simultaneously.
