Abstract:
1. A rotary powder compression molding machine in which a rotary turret is provided within a frame via a vertical shaft so as to be horizontally rotatable, a plurality of dies are provided in the rotary turret at a predetermined interval, an upper punch and a lower punch are held kept above and below each of the dies so as to be vertically slidable, a powder filled in the die is compressed and molded by putting the upper punch and the lower punch in which punch tips are inserted into the dies through a portion between an upper roll and a lower roll, comprising a joint apparatus coupling the vertical shaft and the rotary turret so as to be able to detach the rotary turret from the vertical shaft, wherein the joint apparatus comprises: a coupling mechanism coupling the vertical shaft and the rotary turret while maintaining a state in which the vertical shaft and the rotary turret are constrained in an axial direction of the vertical shaft with each other, and canceling the coupling between the vertical shaft and the rotary turret by canceling the constraining state on the basis of an operation; and a coupling detecting mechanism detecting a fact that the rotary turret is coupled to the vertical shaft by the coupling mechanism, wherein the coupling mechanism comprises:
