METHOD AND APPARATUS FOR TRANSPORTING WORKPIECE IN SCREEN PRINTING MACHINE

PROBLEM TO BE SOLVED: To prevent dislocation during transportation; and reduce impact during transportation, by sequentially performing continuous processing of a series of operations including loading, printing, and unloading of workpieces, on a circulatedly moved identical transport belt. SOLUTION: A loading section 2 for the workpieces W, a printing section 3 for the workpieces W, and an unloading section 5 for the workpieces W are sequentially installed. The transport belt 10 with suction holes 11 punchingly arranged for circulation and intermittent driving among these sections is hung around a machine frame 1. Suction tables 21, 31, and 51 for the loading section 2, the printing section 3, and the unloading section 5 are installed on the lower surface of the transport belt 10, respectively. The workpieces W located at the loading section 2, the printing section 3, and the unloading section 5 are suckingly fixed on the transport belt 10 by sucking action of the suction tables 21, 31, and 51 when the transport belt 10 is intermittently stopped. The workpieces W located at the loading section 2, the printing section 3, and the unloading section 5 are intermittently transported by the transport belt 10 while intermittently suckingly fixing them, by intermittently moving the transport belt 10 upon release of the sucking action or decrease of the sucking action.
