In this paper, it has been proposed an automatic vegetable bundling mechanism that makes use of heat melt sticking. The proposed mechanism is consisted of three modules for the rationality of manufacture. Design specification has been determined by the bundling mechanism that was optimized mechanically. And, it has been manufactured the prototype of the automatic bundling machine. It has been carried out directly the field test for verification of performance in farmhouse which produces vegetable. In field test, this bundling machine showed efficiency of about 3.6 times than the manual working by manpower, and other performance it got satisfied result. This automatic vegetable-bundling machine was already registered as the agricultural machine. and This machine will be commercialized soon.
