Shenzhen, a beer producer governor beer bottle filling production line with the requirements of transport

I. Introduction Mitsubishi inverter speed control mode
Shenzhen, a beer production plant using the Mitsubishi inverter FR-A540E as the main core of the plant equipment requirements for speed bottle filling production line output with the deployment. Mitsubishi Inverter external terminal speed can be divided into analog speed and multi-speed control. Analog speed available DC0 ~ 10V voltage or current DC4 ~ 20mA, variable speed. I plant with a 0 ~ 10V analog voltage as a given quantity, the open-loop speed control; multi-speed with external input terminal STF SD ﹑ ﹑ ﹑ RL RM ﹑ RH, a three-speed control. RL RM ﹑ ﹑ ﹑ RH is low in the third year ﹑ speed speed selection terminal, SD is the input common, STF is to start forward signal. Figure 3, when the Y10, Y11 has output, the inverter is running at low speed; when Y10, Y12 has output for speed run; when Y10, Y13 has output for high-speed operation. Drive 2﹑3 same principle. Three-speed are set to 15Hz 30Hz ﹑ ﹑ 45Hz. When the analog speed by adjusting W1 W2 ﹑ dividing ratio is set at high speed when the drive is closed KA1, KA2 closed during low speed operation, when ﹑ KA1 KA2 are disconnected, the drive for the highest speed; inverter 2 ﹑ three principles and the same. By programming, PLC according to the signal emitted by the console, select the control mode: analog speed or multi-speed control. Mitsubishi inverter multi-speed control has a higher priority (1) than the analog speed control.
Second, the system structure.
2. A process as shown below:

According to process requirements, filling machine in front of the conveyor belt is divided into several sections. ﹑ ﹑ A B C D ﹑ ﹑ E for conveyor, M13 ﹑ ﹑ M15 M14 were dragging motor A ﹑ ﹑ B C band. D and filling machine with a mechanical linkage, E with drag by another motor. Further, each band has a photoelectric sensor to detect the bottle flow velocity. PLC stream segments conveyor speed adjustment according to the bottle.
2.2 electrical system of the original sketch

1﹑2﹑3 inverter control the motor M13 M14 ﹑ ﹑ M15, the main circuit wiring diagram slightly. PLC for FX2-64MR. FMA, 11 is the output signal from the filling machine inverter 0 ~ 10V, after conversion signal isolation as a control signal of inverter 1﹑2﹑3. Figure KA1-6 auxiliary relay. W1-6 is divided piezo positioner. Input terminal PLC slightly. FMA, 11 is the output signal from the filling machine host inverter. Two in the figure for the same PLC PLC, Figure 2 COM6 pick DC24V voltage control auxiliary relay.
Third, control theory
Speed mode converter 1﹑2﹑3 for two: an analog signal from the filling machine host inverter DC0 ~ 10V, through the isolator into a linear DC0 ~ 10V, and then through the potentiometer divider as the inverter 1﹑2﹑3 given signal to control the motor M13 M14 ﹑ ﹑ M15, so the speed of the conveyor belt can be done with a good match filling machine; 2 multi-speed control terminals STF SD ﹑ ﹑ ﹑ RL RM ﹑ RH, through PLC programming, issued by the PLC control signals to control speed. PLC according to the signal emitted by the filling machine console to determine the use of the kind of speed control mode, and select high and low flow conditions in accordance with the bottle. When the analog signal control is through, KA3 KA4, KA5 combination KA1 and KA2 and auxiliary relays and KA6, upon ﹑ W1 W2, W3 ﹑ W4, W5 W6 ﹑ partial pressure control inverter output speed. When multi-speed adjusted separately by each inverter output Y11 Y10 PLC's ﹑ ﹑ ﹑ Y12 Y13, Y20 Y21 ﹑ ﹑ ﹑ Y22 Y23, Y24 Y25 ﹑ ﹑ ﹑ Y26 Y27 output frequency to reach the conveyor speed and multi-stage matches and irrigation match installed speed. In the analog control adjustment potentiometer adjustment points is a critical pressure ratio, groping through commissioning, and finally found a relatively good speed to match. Once adjusted the partial pressure ratio, are not free to change.
Fourth, the application effect

In both speed control mode, respectively, to adjust the frequency and multi-speed potentiometer each inverter dividing ratio, so that the speed of the conveyor belt speed and filling machine good match, stable and reliable. Practice has proved that the inverter FR-A540E fully meet the speed requirements of the beer bottle filling production line output tape. Improve production efficiency. Such drive control method can also be used for other needs of the motor speed with frequency control.
