Rotary compression shaper

本发明提供一种能够高效地制造小批量多品种的压缩成形品的旋转压缩成形机。其具备有将多个下杵分别选择操作为无论该下杵的公转运动如何都固定于上死点的固定状态，和可随着该下杵的公转运动而进行上下动作的动作状态的操作机构。该操作机构例如被设为与多个下杵分别相对应地设置的操作部件。该操作部件可以取与对应的下杵接合而将该下杵固定于上死点的固定位置、和解除与该下杵的接合的动作位置。 It is an object of the present invention to provide a rotary compression molding machine that can achieve a small-lot production of molded products of various shapes and sizes in an efficient manner. An operation mechanism is provided to selectively bring each of lower punches into a fixed position so as to hold the same at an upper limit regardless of the rotational motion of the lower punches about a rotating vertical axis, and an operating position so as to allow the same to be vertically movable according to the rotational motion of the lower punches. The operation mechanism may be in the form of operation members respectively provided to the lower punches. The operation members each are capable of taking a fixing position enabling itself to be engaged with a corresponding lower punch so as to hold the same at the upper limit and an operating position enabling itself to be disengaged from the lower punch.
