摘要： PURPOSE:To measure independently the force actuating on adjacent bearings at the same time with one load detector by forming two bridges utilizing strain gages respectively between fixed parts of both ends of a beam and the bearing load actuating positions of the central two places. CONSTITUTION:Both ends 11A and 11B of the beam 10 are fixed and the load actuating positions of the roll bearings 1 and 1' are provided at an interval in the right and left direction at the two places of the central part of the top of the beam 10. Slits 16A, 16A', 16B and 16B' which are pierced in the direction of the thickness of the beam 10 are provided between each load actuating position and the tip of the beam 10 and the strain gages P+, P-, Q+, Q-, R+, R-, S+ and S- are stuck to these inner walls and the bridges BR1-BR4 to detect the shearing power generating between each load actuating position and the fixed parts of both ends are formed. Then, the bridges BR1 and BR3, and BR2 and BR4 are added in parallel respectively and on that occasion, a proportional constant of an operation expression of the actuating load determined by the length of the beam 10, the load actuating positions and the fixed conditions of both ends is fitted by the size of correction resistance put at the primary sides of the bridges BR1-BR4 to obtain outputs in proportion to the size of the loads W1 and W2.

摘要： PURPOSE:To detect a tensile load easily and precisely by providing a strain generation part consisting of a couple of slits between the fixation part of a load cell and a loaded part, and measuring bending strain generated at the strain generation part. CONSTITUTION:The load cell 8 is incorporated in a rolling mill stand in a both- end fixed beam state so that both end parts with an attachment surface 15 serve as fixation part 18 and the center part operates as the loaded part 19. The strain generation part 21 consists of a couple of slits 22a and 22b; strain gauges 25 and 26, and 27 and 28 are adhered to center positions of plate thickness in the direction of a neutral axis and strain gauges 29 and 30, and 31 and 32 are adhered crossing each other at 45 deg. to the neutral axis. A tensile load X is bending moment to both end fixed beams and a rolling load Y is shear force and converges to the strain generation part 21; the bending strain is detected by the strain gauges 25-28 and the shear strain is detected by the strain gauges 29-32.

摘要： PURPOSE:To detect three forces and three moments at a high accuracy, by connecting upper and lower parallel substrates together with a total of six detection columns which are arranged on a circumference at respective positions equally divided by 120 deg. in such a manner as to be at a fixed angle to the vertical direction. CONSTITUTION:This apparatus is made up of upper and lower substrates 1 and 2 arranged parallel, a total of six detection columns 3-8 which are arranged in pairs of two each on a circumference at respective positions equally divided by 120 deg. in such a manner as to be at a fixed angle to the vertical direction to connect both the substrates 1 and 2 and strain gauges 11-16 provided on the detection columns 3-8. When an external force allowed to be divided into forces in three axes (x), (y) and (z) and moments Mx, My and Mz about three axes works on the substrates 1 and 2, a tension force or a compression force acts upon each of the detection columns 3-8 in a fixed relationship with the forces and the moments. The tension or compression forces are detected with the gauges 11-16 and an axial force working on the detection columns 3-8 permits accurate detection of the three-axis-wise forces and moments.

摘要： PURPOSE:To measure accurately the friction force between a casting mold and a billet and to monitor effectively the casting condition by applying oscillation to the casting mold and detecting the displacement of the mold by the oscillation and resistance force. CONSTITUTION:A displacement signal x(t) 9 of a casting mold by oscillation is subjected to an AD conversion. The output from an AD converter 11 and a preset spring constant (k) are multiplied by a circuit 12 and a spring force kx(t) is calculated. The signal x(t) is differentiated twice by differentiation circuits 13, 14 and the result thereof is subjected to an AD conversion. The output from an AD converter 15 and preset total mass M are multiplied by a circuit 16 and inertial force M.d x/dt is calculated. On the other hand, a signal P(t) 10 for resistance force of the casting mold by the oscillation is subjected to an AD conversion by an AD converter 17. Friction force F(t)=P(t)XM.d x/dt Xkx is calculated by an arithmetic circuit 18 from the output from said converter, the output kx(t) from the circuit 12 and the output M.d x/dt from a circuit 16.

摘要： PURPOSE:To weight a massive object with variance for single weight with one balance to the target weight by supplying a large vessel with a weigher with an object to be weighed and performing the rough weighing and calculating a short amount with the target weight and adding in combination out of a small quantity of plural objects to be measured and selecting a combination most close to the short amount. CONSTITUTION:First, a large quantity of supply is performed from a main feeder 10 to the large vessel 1 and the weight W0 is measured with load cells 21-2n. On the other hand, an object to be weighed is supplied one by one from secondary feeders 111-11n to small vessels 31-3n and lowered by elevators 41-4n every one piece and rested on a supporting plate 5 of the top of the large vessel 1 and weighed with the load cells 21-2n. Then, the weights W1, W2-Wn of the objects to be weighed in the small vessels 31-3n are adjusted in gross weights and weighed by a controller, and m pieces of combination most close to the difference between the target weight Ws and the weight W0 of the object to be weighed in the large vessel 1 are selected. Then, the selected objects to be weighed in the small vessels are charged into the large vessel 1 and mixed therein, and the objects to be measured in the large vessel 1 attaining the target weight are supplied to a next process.

摘要： PURPOSE:To enable the detection of distortion at a high accuracy without increasing the length and diameter of a pin, by inserting a sleeve in the circumference of a pin to be made in a double axis so that only the center of inner circumference of the sleeve will be brought into contact with the circumference of the pin. CONSTITUTION:A pin 1 is supported with shaft holes 3 and 3' provided on side plates 2 and 2' arranged at an interval (b) with the diameter (d) while the pin 1 is cased with a sleeve 4 whose inner diameter at the axis-wise center is small while the inner diameter at both ends thereof large. The sleeve 4 is so arranged as to contact the circumference of the pin 1 only in the section CC' (with the distance of roughly b-2d) at the center and not in the sections AC and A'C' [with the distance of (d)] at both ends. At this point, the force W working on the entire area between the side plates 2 and 2' acts on the pin 1 concentrating on the section CC' at the center where the sleeve 4 contacts the pin 1 to create the sections AC and A'C' necessary for the detection of distortion at a high accuracy.

摘要： PURPOSE:To stabilize deformation of a beam body due to the working load and to perform load detection with high accuracy by incorporating a fixed base with rigidity with a fixed part of the beam body. CONSTITUTION:When a body to be detected is loaded on a loading part 5 of the body to be detected of the beam body 1, the bending moment WS is generated on the beam body 1 of which the fixed part 2 is incorporated with the fixed base 3 at the other end side by the load W worked on a load working part 6. The bending moment WS is detected by strain gages 8, 8 to measure the magnitude of the load W. At that time, the fixed part 2 and the fixed base 3 are being bent by the bending moment WS but the base 3 has the rigidity to resist the bending moment WS and is not almost deformed. The deformation due to the working load W of the beam body 1 generating distortion can be stabilized by incorporating the base 3 which is not deformed with the fixed part 2 with the same rigidity. In this way, the measuring accuracy can be improved.
