Claims

[Claims for Utility Model Registration] (1) A movable conveyance unit equipped with a pair of gripping means that can be opened and closed, and a drive unit for reciprocating the conveyance unit in a predetermined section. and a workpiece conveyance device for gripping a workpiece by the pair of gripping means and transporting the workpiece from a first position to a second position, wherein the workpiece is opened and closed by an external driving force. an opening/closing driving means mounted on the conveying section; and an opening/closing driving means provided near the first position that engages with the opening/closing driving means when the conveying section reaches the first position and applies a driving force in the closing direction to the opening/closing driving means. a first driving source that is provided near the second position and that engages with the opening/closing drive means to apply a driving force in the opening direction to the opening/closing driving means when the conveyance section reaches the second position; A workpiece conveyance device comprising: a second drive source. (2) The opening/closing driving means is a pair of brackets each having a different thread cutting direction, each screwed onto a pair of brackets to which the pair of gripping means are attached, and each end of which is connected at a substantially central portion between the pair of brackets. 2. The workpiece conveyance device according to claim 1, further comprising a pair of helical shafts, each having an engaging portion at the other end of the pair of helical shafts to engage with the first and second drive sources. (3) At least one of the pair of gripping means,
2. The workpiece conveyance device according to claim 1, further comprising means for detecting that the gripping force between the two has reached a predetermined value.
