摘要： A vertical moving method of a vertical moving unit on which a conveyance target object is mounted includes steps of causing a non-electric biasing unit to generate a biasing force to raise the vertical moving unit, causing an electric motor unit to generate a thrust in a direction to raise the vertical moving unit or a thrust in a direction to lower the vertical moving unit, and causing an electromagnetic brake unit to generate a braking force to resist a movement of the vertical moving unit. Independently of presence/absence of the object and a weight of the object, the thrust and/or the braking force is controlled such that the vertical moving unit stops when an external force of overload more than a predetermined value acts on the vertical moving unit during a vertical movement.

摘要： This invention provides a stop device that abuts against a work during conveyance and stops the work. The stop device includes a stop lever stopping the work at a predetermined stop position, a movable unit supporting the stop lever so as to pivot the stop lever in a predetermined range, a biasing unit biasing the stop lever toward an upstream side, a driving unit displacing the movable unit between a working position and a retraction position, and an auxiliary stop unit arranged in the movable unit. The auxiliary stop unit includes a work abutment portion at the same position as a conveyance stop position where the stop lever stops conveyance of the work, or at a position on the downstream side in the conveyance direction from the conveyance stop position.

摘要： A stopping apparatus according to the invention includes a swing unit pivotal about a first pivot shaft between an abutment position in which the swing unit abuts against a work to stop conveyance of the work and a retreat position, a driving unit, and an elastic member applying a biasing force to the swing unit in a direction in which the swing unit is located at the abutment position. The swing unit includes a swing portion pivotal about the first pivot shaft and a movable portion including an abutment portion abutting against the work. The movable portion is pivotally connected to the swing portion. The movable portion pivots relative to the swing portion such that a distance between the first pivot shaft and the abutment portion becomes short along with a pivot motion of the swing unit to the retreat position.
