自由高さ測定装置。[Claims for Utility Model Registration] A chute that allows the coil spring to fall freely with its axis parallel to the falling direction, and a first tip detection device that is placed midway through the chute and detects the tip of the coil spring that freely falls on the chute. A detector is placed on the side of the chute behind the first tip detector, and when the first tip detector detects the tip of the coil spring, the position of the rear end of the coil spring is in the detection range. a rear end detector that outputs a signal to detect the free height dimension of the coiled spring and calculate the free height dimension of the coil spring; a second tip detector that detects the tip of the coil spring; and a time required from the point in time when the first tip detector detects the tip of the coil spring to the point in time when the second tip detector detects the tip of the coil spring. and a computer that calculates the falling speed of the coiled spring based on the falling speed, corrects the free height dimension of the coiled spring obtained by the rear end detector based on the falling speed, and outputs a display and pass/fail judgment. A device for measuring the free height of a coiled spring.
