摘要： PURPOSE:To provide a measuring device having a simple structure with less vibration by linearly scanning a plurality of positions on a coil with a plurality of leaser beams with the use of a transverse runner, and by traversing the transverse runner during the scanning so as to collect data necessary for the positional measurement. CONSTITUTION:A laser distance meter 30 is attached, facing downward, to a transverse runner 20 which can freely run in the X-axial direction above a coil 10 introduced into a coil yard, and which can slightly move in the Y-axial direction. The laser distance meter 30 has a plurality of projecting parts Pa to P11 for projecting laser beams right downward, which are located in the center part of the transverse member 20 in the X-axial direction, and which are arranged at predetermined pitches in the Y-axial direction. The laser distance meter 30 receives reflected beams of the laser beams projected from the projecting parts P1 to P12 at light receiving parts M1, M2 so as to measure distances to reflecting points. A controller stores therein distances to a plurality of points measured by the laser distance meter 30, corresponding to the moving positions of the transverse runner 20, and performs several kinds of computation for specifying the position of the coil.

摘要： PURPOSE:To Precisely measure a position of a coil with the use of a laser distance meter. CONSTITUTION:A laser distance meter 34 moves in X- and Y-axial directions above a coil 10, and delivers a laser beam right downward from a light projecting part 32a, and receives a reflected beam at a light receiving part 34b on a light receiving axis B which is inclined from a light projecting axis A so as to measure a distance to a reflecting point, The light receiving axis B turns around the light projecting axis A of the laser distance meter 34. The laser distance meter 34 reciprocates above the coil 10 so to detect a position of an edge of the coil 10. When the laser distance meter 34 passes over the edge part of the coil 10, the light receiving axis is directed outside of the coil 10, and accordingly, it is possible to eliminate a measuring disable section due to a blind spot.

摘要： PURPOSE:To correctly measure the position of a coil which is positioned on a pallet, by a simple device. CONSTITUTION:The position of a pallet 11 is obtained by measuring each distance to the front and rear legs 11a and 11b of the pallet 11 by each laser distance meter 31a, 31b. The climb 21 of an automatic operating crane 20 is led on the pallet 11, and the crab 21 is shifted along the center line of the pallet 11. At this time, the part on the pallet 11 is scanned by the laser distance meter 32 installed on the crab 21, and the position of a coil 10 in the center line direction of the pallet 11 is measured. The position of the coil 10 on the pallet 11 is measured by using three laser distance meters 31a, 31b, and 32.

摘要： PURPOSE:To detect a preceding input article even if conveyed articles are stacked in multiple stages. CONSTITUTION:An automatic crane 1 is provided with an ultrasonic distance sensor 30. While the automatic crane 1 is passed through a measuring position of the ultrasonic distance sensor 30 with a moving speed reduced at a forward position of an indicated position, an ultrasonic wave 32 is directed to a floor surface for scanning during the passing so as to detect presence of a preceding input article based on a receiving output waveform of the ultrasonic wave 32 returned by reflection. The automatic crane 1 is once stopped in the vicinity of a forward position of an indicated position and a propagation delay time of the ultrasonic wave 32 is detected by the ultrasonic distance sensor 30 to detect presence of a preceding input article. If absence of a preceding input article is determined, a conveyed article is conveyed to the indicated position.

摘要： PURPOSE:To perform bracing positively by stopping a crane in a position slightly more to the front by the specified quantity than the target position so as to provide the crane with correcting distance and suppresing the residual oscillation within this correcting distance. CONSTITUTION:When the length of a rope 5b and the weight of a lifted load are detected, a reference pattern generating device 1 generates a reference pattern formed of such a speed pattern that oscillation generated by the acceleration/deceleration of a crane 5 at the time of being moved by the specified distance becomes zero at the stop time of the crane 5, and the oscillation of the lifted load 5c at the time of the acceleration/deceleration including the stoppage of the crane 5 being zero is detected at a detecting device 2a. A correction pattern generating device 2a generates a correction pattern formed of such a speed pattern as to make this detected oscillation zero, and the correction pattern is added to the reference pattern at the combining device 3, thus stopping oscillation of the lifted load 5c. The crane 5 is stopped once in a position more to the front by the specified quantity than the target stop position and then subjected to the suppression of residual oscillation as well as positioning.
