Stopping apparatus and stop-canceling method

A stopping method for causing a stopping apparatus to abut against a work being conveyed to stop the work,

• the stopping apparatus comprising a swing unit, a regulating mechanism and a pivot regulating member,
• the swing unit including an abutment portion that abuts against the work being conveyed,
• the swing unit being 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 the abutment portion 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,
• the swing unit comprising
• a swing portion that is pivotable about the first pivot shaft,
• a movable portion including the abutment portion, the movable portion including a first end and a second end, the abutment portion being provided at a side of the first end,
• the movable portion being connected to the swing portion to be pivotable through a second pivot shaft at a side of the second end,
• the second pivot shaft being parallel to said first pivot shaft,
• the regulating mechanism regulating a moving range of a portion between the abutment portion and the second pivot shaft in the movable portion and guiding a motion of the movable portion about said second pivot shaft, and
• the pivot regulating member performing pivot regulation of the swing unit by engagement with the swing portion and cancellation of the pivot regulation,
• the method comprising
• a step of causing the work abutment portion to abut against the work, and
• a step of stopping the work,
• wherein said step of stopping the work includes
• a step of regulating a pivoting motion of the movable portion about the second pivot shaft in a first direction by the regulating mechanism against a bending force between the movable portion and the swing unit due to a convey force of the work, and
• a step of regulating a pivoting motion of the swing portion about the first pivot shaft in a second direction opposed to the first direction by the pivot regulating member against the bending force.

A stopping and stop-canceling method for causing a stopping apparatus to abut against a work being conveyed to stop the work and then canceling the stop of the work,

• the stopping apparatus comprising a swing unit, a regulating mechanism and a pivot regulating member,
• the swing unit including an abutment portion that abuts against the work being conveyed at a predetermined stop position to stop conveyance of the work,
• the 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 the abutment portion 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,
• the swing unit comprising
• a swing portion that is pivotable about the first pivot shaft
• a movable portion including the abutment portion, the movable portion including a first end and a second end, the abutment portion being provided at a side of the first end,
• the movable portion being connected to the swing portion to be pivotable through a second pivot shaft at a side of the second end,
• the second pivot shaft being parallel to said first pivot shaft,
• the regulating mechanism regulating a moving range of a portion between the abutment portion and the second pivot shaft in the movable portion and guiding a motion of the movable portion about said second pivot shaft, and
• the pivot regulating member performing pivot regulation of the swing unit by engagement with the swing portion and cancellation of the pivot regulation,
• the method comprising
• a step of causing the work abutment portion to abut against the work,
• a step of stopping the work, and
• a step of canceling the stop of the work,
• wherein said step of stopping the work includes
• a step of regulating a pivoting motion of the movable portion about the second pivot shaft in a first direction by the regulating mechanism against a bending force between the movable portion and the swing unit due to a convey force of the work, and
• a step of regulating a pivoting motion of the swing portion about the first pivot shaft in a second direction opposed to the first direction by the pivot regulating member against the bending force, and
• wherein said step of canceling the stop of the work includes a step of pivoting the swing portion about the first pivot shaft in the second direction and pivoting the movable portion about the second pivot shaft in the first direction with guiding the movable portion by the regulating mechanism.
