Abstract:
1. A stopping apparatus for abutting against a work being conveyed to stop the work, comprising: a swing unit pivotal about a first pivot shaft downstream of a predetermined stop position in a convey direction of the work between an abutment position at which said swing unit abuts against the work being conveyed at the predetermined stop position to stop conveyance of the work and a retreat position which allows passage of the work; a driving unit configured to pivot said swing unit from the abutment position to the retreat position; and an elastic member configured to apply a biasing force to said swing unit in a direction to locate said swing unit at the abutment position, wherein said swing unit comprises: a swing portion pivotal about the first pivot shaft; and a movable portion including an abutment portion configured to abut against the work, said movable portion being pivotally connected to said swing portion through a second pivot shaft parallel to the first pivot shaft, and said movable portion pivoting in the predetermined direction relative to said swing portion such that a distance between the first pivot shaft and the abutment portion becomes short along with a pivot motion of said swing unit from the abutment position to the retreat position by said driving unit, and wherein when the work being conveyed abuts against said swing unit, the pivotal motion of said swing unit from the abutment position to the retreat position by an urging force from the work is regulated by a biasing force of said elastic member.
