Inventor: FUKUTAKA YOSHIKI
IPC: G01B11/24
Filed: 1983-12-19
Abstract: PURPOSE:To elevate the measuring accuracy of a telescoping value by a method wherein after a telescoping value is obtained from a specified measured distance value at the diametrical position of a coil, an approximation is made on the measured distance value and the diametrical position of the coil by the secondary regression curve to pass a judgement from the square sum of deviation and the curve coefficient thereof. CONSTITUTION:Laser distance meters 22 are arranged as opposed to each other at the lower end face 10A of a coil 10 moving on a conveyor 20 and outputs thereof and output of a pulse transmitter 24 are fed to a microcomputer 28. The computer 28 takes in the outputs of the distance meters 22 at each signal of the transmitter 24 and traces the maximum value thereof to define it as the measured distance value corresponding to the diametrical position of a coil. When the frequency of continuation showing the data exceeding the upper limit of the measuring range is above the set value, the end of measurement is determined. Then, a telescoping value is determined from the measured distance value thus obtained, an approximation is made on the relation between the measured distance value and the diametrical position of the coil by the secondary regression curve to pass a judgement from the square sum of a deviation and the curve coefficient thereof.

IPC: B25J13/00
Filed: 1996-08-23
Abstract: PROBLEM TO BE SOLVED: To shorten an operation cycle time in the operations of a robot and a work machine mobile part including a smooth operation. SOLUTION: In a corner part where the smooth operation is instructed, cos θ of a corner angle θ is obtained by the inner product of the mobile vector of an applying block and the mobile vector of the succeeding block(A3, A4 and A5). Then, a coefficient k is obtained by an expression, k=1+0.5(1-cos θ)(A6). A value T is obtained by multiplying a positioning time constant T0 by the coefficient(A7). The value T is adopted as the decerelation time constant Tb and the accerelation time constant Ta of the corner part (A9 and A11). K=1 is adopted at the time of θ=0 (straight line) and Ta and Tb become the positioning time constant T0. When θis 180 deg. in a reverse operation, Ta and Tb become 2T0 by k=2, the time constant is adjusted and an accerelation processing is executed in a min. time within the output torque limit value of a servo motor.

Further, a supporting apparatus regulates so that a pair of magnets 3a, 3b are positioned to a transfer block end C from a waiting position D. Thereby, the magnetic fluid 7 will receive a magnetic field from a pair of the magnets 3a, 3b. Then, since a pair of the magnets 3a, 3b return to pause positions B by a spring mechanism, the magnetic fluid 7 is moved to an orifice 1a from a position receiving the magnetic field from electromagnets 4a, 4b. At that time, since counter poles of a pair of the magnets 3a, 3b are different poles, the magnetic fluid 7 closes the orifice 1a when an apparatus pauses, and ink in the nozzle is isolated from the open air thereby.
