Abstract: Provided is a load measuring device and a load measuring method, capable of preventing a measuring error caused by an initial load in a state where an elastic member is held by a pair of holding parts when a load of the elastic member at the time of stretching is measured. A pair of holding parts 5, 7 are caused to approach or space away with respect to each other relatively to an initial position at which the pair of the holding parts hold a close contact spring S, thereby making an initial load measured at the initial position zero, the pair of holding parts 5, 7 are caused to space away with respect to each other from a starting position being a position at which the initial load becomes zero, and a load at a time of stretching is caused to be measured.

Abstract: A work hanging apparatus includes a hanger line continuously conveying hangers each having a hook, a robot that has a hand with which a work having a hole is held and transfers the held work to a hanging location set in the hanger line, a controller controlling a movement of the hand to catch the hook of one of the hangers with the hole of the held work at the hanging location, a hole deviation detector that detects a positional deviation of the hole of the work, an attitude deviation detector that detects an attitudinal deviation of the hanger, and a corrector that corrects the movement of the hand according to the positional and attitudinal deviations.

Abstract: A coil wire material is bent by a first roll, a second roll, and a third roll. The bent coil wire material is pressed in a screwing direction, to shape a coil spring having a desired diameter and a pitch. A desired pitch can be accurately formed in a manner that a second roll provided on a downstream side of a conveying direction of the coil wire material is configured to be able to move hack and forth along the screwing direction of the coil spring and to be tiltable about an axis of rotation parallel to the conveying direction of the coil wire material.
