Abstract

PURPOSE:To control the thrusts of bellows by disposing a thrust generator which generates the thrusts corresponding to the internal pressures of the bellows in parallel with the bellows and transmitting the thrusts of the thrust generator to the bellows so as to negate the thrusts thereof. CONSTITUTION:A bellows 15 is disposed as a thrust generator in, for example, internal pressure type, in parallel with the bellows 5 between pressurizing tanks 2 and 3. When pressure is exerted upon the inside of the bellows 5, the bellows 5 extends and generates the thrusts in the direction for forcing the tank 2 for supplying upward and in the direction forcing the tank 3 for transporting downward respectively. Since the thrusts are transmitted via levers 16a, 16b to the bellows 15, the bellows 15 receives the force in a shrinking direction. When pressure is exerted upon the bellows 15 in this state, the thrusts by the extension thereof are applied via the levers 16a, 16b to the bellows 5; therefore the thrusts act as the inverse thrusts in the directions opposite from the thrusts of the bellows 5, whereby the thrusts of the bellows 5 are negated.

This can be achieved by adjusting the position r&f of the bellows (g) and/or the bottle c However, since the bellows (5) and OQ are independent systems, the difference in thrust between the bellows can be corrected by adjusting the pressure of the bellows oF9. That is, assuming that each bellows is of the internal pressure type, when the thrust of the bellows (5) is large in reverse thrust from the bellows (toward) to the rear end (16a and 16b), the supply pressurized tank (2) K is an upward thrust, and a downward thrust is applied to the Calo pressure tank (3) for transportation. By setting the indicated value of the vehicle to be the value before applying pressure to each bellows, the weight of each pressurized tank (2) +3) can be accurately measured against acid. In the case of bellows (15

As described above, according to the method of the present invention, in the bellows that connects a pressure source insulated, the thrust generated when pressure is applied to the bellows is canceled out by the reverse thrust of the thrust generator arranged in parallel. This can eliminate or reduce the load on the pressure source connected to both ends of the bellows as the bellows stretches, especially when measuring the weight of the pressure source connected to both ends of the bellows. It has excellent features such as being able to accurately weigh one weight by eliminating gravitational interference between the two.

An arbitrary load can be applied to the pressurized tanks (2) and (3) connected to the bellows. In other words, when controlling the amount of granular material cut out from the pressurized transportation tank (3) as shown in FIG. It is necessary to measure the speed to the correct value (i), but as mentioned above,
) is 40-s OQ.
This can be corrected by the reverse thrust caused by However, when charging powder or granules from the supply pressurized tank (2) to the Qtd feed cuff pressure tank), the weight of the transport force 11 pressure kunk (3) is as shown by the solid line A in Figure 6. From the feeding start time ts to the feeding stop time tt! Add up to 497. In addition, the third

By adjusting the pressure of the bellows OQ, the thrust of the bellows (5) can be adjusted. In order to measure only the cut-out weight speed w2 in this state where it is possible to reduce the weight to zero, it is necessary to eliminate the supplied weight speed Wl from the actual pressurized tank weight speed W.
