れない欠点がめった。In this type of pneumatic transport machine, the air flow rate ratio injected into the blow tank and the transport pipe is fixed to a constant value by the opening degree of the hand-cut valve. For this reason, when the pressure of the blow tank was increased, a large amount of air flowed into the transport pipe, resulting in the drawback that the pressure of the blow tank could not be increased sufficiently.

The replacement air is enclosed through the exhaust valve 3 and exhausted through the exhaust valve 4. One feed into blow tank 2'+31J1
When the tank is full, the intake valve 3 and the air tank 4 are closed. On the other hand, the compressor 5 generates three-wheel fresh air δ, and this pressure IflI air is taken out through the piping 6 and the cap air tank 7 and distributed into three parts. That is, the first thread path is connected to the blow tank via the pressure regulator 8 and the air pipe 9, and the second thread is connected to the transport pipe 12 through the pressure regulating valve 10 and the air pipe 11. a third line connected to the air line 13 and the control valve 14'k, Jr to the transfer line d12, respectively. The end of the transfer #12 is connected to the exit of the blow tank 2, and the other end is connected to the destination tank 15&C. The control valve 14 is controlled by a control device 17 whose information input is a detection signal from a pressure detection device ft16 that detects the pressure inside the floater 2.

率が高められる。In general, the pressure in the blow tank 2 can be increased by increasing the air flow rate in the air line 8 and reducing the air flow cover of the air pipe 11 or 13, and the pressure can be decreased by the reverse operation. I can do it. Therefore, in the present invention, the pressure of the blow tank (c) is detected by a pressure detection device, and based on this detected value, the control valve 14 is closed at a time when the transport pressure is low, such as at the start of transport, and the tank pressure increases. Now, if the transport pressure is too high, open the control valve 14 (i-) and turn the air to the pail feeder 13 to 1r.
1 by fft17, which controls the palm transportation pressure to a constant value. IJ1iI41 is running. like this? 1I
IJ wholesale factory! The increase in the 7-shaft pressure is controlled with good responsiveness, and the transport pressure is automatically adjusted to be continuous, increasing transport efficiency.

不安定で、昇圧が緩やかであることがわかる。By providing the thread path for the control valve 8, the @feeding pressure characteristics become as shown in Figure 2, showing a constant pressure value, and
It can be seen that by increasing the external pressure of the blow tank, the transport pressure becomes stable. According to the results of the experiments conducted by the inventors, it was confirmed that the time for one transport can be reduced by about 121 points. Incidentally, if the conventional transport pressure characteristics were eliminated, the result would be as shown in FIG. 3, which shows that the transport pressure is unstable and the pressure increase is gradual.

You may do so.
