1. A stopping apparatus that abuts against a work being conveyed to stop the work, comprising:
a swing unit that is pivotable about a first pivot shaft on a downstream side of a predetermined stop position in a convey direction of the work between an abutment position where said swing unit abuts against the work being conveyed at the predetermined stop position to stop conveyance of the work and a retracted position which allows passage of the work, a driving unit that pivots said swing unit, a regulating mechanism, and a pivot regulating member, wherein said swing unit comprises: a swing portion that is pivotable about the first pivot shaft, and a movable portion including an abutment portion which abuts against the work, wherein said movable portion includes a first end and a second end, wherein said abutment portion is provided at a side of the first end, wherein said movable portion is connected to said swing portion to be pivotable through a second pivot shaft at a side of the second end, wherein said second pivot shaft is parallel to said first pivot shaft, wherein said regulating mechanism regulates a moving range of a portion between said abutment portion and said second pivot shaft in said movable portion and guides a pivoting motion of said movable portion about said second pivot shaft, wherein said pivot regulating member performs pivot regulation of said swing unit by engagement with said swing portion and cancellation of the pivot regulation, and wherein when a work being conveyed abuts against said abutment portion in the abutment position: a convey force of the work is received by at least said regulating mechanism and said pivot regulating member, pivoting of said movable portion about said second pivot shaft is regulated by said regulating mechanism, and pivoting of said swing portion about said first pivot shaft is regulated by said pivot regulating member. |
