PROBLEM TO BE SOLVED: To provide a conveyance device capable of shortening cycle time by safely and promptly starting conveyance of a work put between a pair of molds after a press work in an underdrive type press machine.SOLUTION: A conveyance mechanism 5 in which a bolster table T for supporting a lower mold 1, and a knockout member K for taking out a work to be accommodated in the lower mold 1 are independently made liftable by a lifting mechanism 3, and interlocked with lifting of the bolster table T puts a work W from a conveyance path 51 in rise of the lower mold 1. After performing a press work of the work W between the lower mold 1 and an upper mold 2, drive control means 7 moves the knockout member K at the same speed in the opposite direction of a movement direction of the bolster table T, makes the work temporarily stand still at height of the conveyance path 51, and makes the work W conveyable by an opening/closing operation of a chuck member C and a feed operation in a horizontal direction during fall of the bolster table T. |
