ROD MEMBER EXTRUSION-MOLDING SYSTEM AND EXTRUSION-MOLDING METHOD THEREFOR

摘要

This system for implementing a rod member extrusion-molding method has the following: an extrusion molding machine (10) for a rod member (R); a transfer conveyor (14); a delivery line (DL) for the rod member (R) between the extrusion molding machine (10) and the transfer conveyor (14); a measurement position (MP) that is defined on the delivery line (DL) and demarcates the delivery line (DL) into an upstream section (UDL) and a downstream section (DDL); a measurement device (16) for measuring an outer radius (DR) of the rod member (R) at the measurement position (MP); a first roller conveyor (28) for forming a part of the section (UDL) at least directly upstream of the measurement position (MP); a second roller conveyor (30) for forming the downstream section (DDL); and a control device (18) for implementing feedback control of the speed of transfer of the transfer conveyor (14) on the basis of the outer diameter (DR) obtained by the measurement device (16).
