1. A stopping apparatus that abuts against a work being conveyed to stop the work, comprising:
a swing unit including a work abutment portion that abuts against the work being conveyed at a predetermined stop position to stop conveyance of the work, said swing unit being pivotable about a first pivot shaft on a downstream side of the predetermined stop position in a convey direction of the work between an abutment position where said work abutment portion protrudes above a lower surface of the work and a retracted position where said work abutment portion moves below the lower surface of the work to allow passage of the work, and a driving unit that pivots said swing unit, wherein said swing unit comprises: a swing portion pivotable about the first pivot shaft, and a movable portion including said work abutment portion, wherein said movable portion is connected to said swing portion to be pivotable through a second pivot shaft parallel to the first pivot shaft so as to shorten a distance between the first pivot shaft and said work abutment portion along with pivoting motion of said swing unit from the abutment position to the retracted position, and wherein said driving unit comprises: a swing unit elastic member that applies a biasing force to said swing unit in a direction to locate said swing unit to the abutment position, and an electrically driven actuator including a connecting portion connected to said swing unit and a driving portion that moves said connecting portion in a direction to pivot said swing unit to the side of the retracted position, and said stopping apparatus further comprises a pivot regulating member that performs pivot regulation of said swing unit by engagement with said swing unit and cancellation of the pivot regulation by moving interlockingly with an operation of said driving unit. |
