摘要： A conveyance method of conveying a conveyance target object by loading the conveyance target object on a slider, wherein the slider is connected to a ball nut threadably engaged with a ball screw shaft, includes a step of rotating the ball screw shaft by an electric motor, a step of applying a braking force which is a rotation resistance to the ball screw shaft by a non-electric resistance changing unit, and a step of setting at least one of a driving force of the electric motor and the braking force of the resistance changing unit so that the slider will stop when a predetermined external force acts on the slider during conveyance and changes the slider to an overload state regardless of the presence/absence of the conveyance target object loaded on the slider and a weight of the conveyance target object.

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.

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.
