WORK CONVEYOR

PURPOSE:To enable conveyance of different shaped works with a common pallet in a work conveyor for conveying the pallet on which the works are mounted by rotating a prismatic pallet that a plurality of mounting surfaces for different shaped works are formed on the outer circumference so as to have a predetermined mounting surface at the position capable of input. CONSTITUTION:In a pallet P, end plates 102 and 103 are formed on both sides of a body part 101 in the shape of an almost triangle pole, and a positioning bracket 104 in the shape according to the type of a work W and a positioning pin 105 are provided on the three side surfaces so as to form mounting surfaces for the works whose shapes are different from each other. In the meantime, a pallet rotation mechanism R is provided at the terminal (left end) of a lower stage conveyor C1 on the upper stream side of a work input station S1 so as to rotate the pallet P so that the mounting surface according to the work W is used. And it is raised to the work input position of an upper stage conveyor C2 by a lifting mechanism L1. By this constitution, different shaped works can be conveyed on the common pallet.
