PURPOSE:To narrow installation space by simplifying a structure and to enhance general-purpose properties. CONSTITUTION:A molded product 23 is taken out of an injection machine 1 by a robot 3 to be carried to a gate cutting device 6 to cut the gate of the molded product and the wt. of the molded product is measured by a weighing device 7 and the weighed molded product is placed on the belt 43 of a sizing intermittent transfer device 8 to be transferred while intermittently stopped at respective positions I-VI. A device 9 inspects the appearance of the molded product at the position I, and a device 10 inspects the dimension of the molded product at the position II and a device 12 inspects the printing of the molded product at the position V. When the molded product is judged to be inferior by the weighing device 7 and the respective devices 9, 10,12, the molded product is discharged out of the system by the robot 3 or pushers 52, 57, 58. Other molded product 26 is fitted to the molded product 23 at the position III by other robot 4 and, when the molded products are transferred from the position III to the position IV, a device 11 applies printing to the molded products. A device 13 counts the number of products S at the position VI and the products are put in a tray 61 by the robot 3. A structure is simple and installation space is narrow. Since the devices 9-13 are easily increased or decreased in number and rearranged, general- purpose properties are enhanced.
