Cased coil spring producing apparatus

摘要

A cased coil spring producing apparatus (1) comprises a coil spring producing mechanism (3) for forming coil springs (2); a conveying mechanism (7) including a conveyer (4) for conveying the coil springs fed from the coil spring producing mechanism; a hardening-and-cooling mechanism (8) for hardening the coil springs and cooling them; a sheet feeding mechanism (10) for double folding a sheet (9) and feeding it; a compression-and-insertion mechanism (11) for compressing the coil springs and inserting them in the double folded sheet; a banding mechanism (12) for bonding the double folded sheet inserting therein the coil springs together; and a coil spring arraying mechanism (13) for changing position of the coil springs inserted in the sheet, wherein the conveyer of the conveying mechanism includes coil spring supporting members (5) aligned in two or more rows rising upwardly therefrom, and wherein a sorting mechanism (6) is provided for sortably distributing the coil springs fed from the coil spring producing mechanism to the coil spring supporting members.
