Automatic filling machine technical troubleshooting method

Shanghai Guangzhi Instrument Equipment Co., Ltd. specializes in producing all kinds of packaging equipment, filling equipment, mechanical equipment and other equipment series. The automatic filling machine is a technical automatic intelligent irrigation developed by the technicians of Shanghai Guangzhi Instrument Equipment Co., Ltd. Installed, simple operation, high precision and accurate measurement.

Automatic filling machine technical troubleshooting method

The working principle of the automatic filling machine , the high-precision liquid quantitative filling machine - is the mechanical rotary type, the atmospheric pressure filling, the quantitative cup, the filling valve is fully enclosed, and the automatic type is transmitted by the bottle line. Empty bottle, through the bottle dial mechanism, no empty bottle will be sent to the turntable accurately, the empty bottle will rotate immediately, and the empty bottle will be lifted by the soft support mechanism, and the bottle mouth will automatically open after contact with the filling valve. After filling and filling, the bottle is automatically pulled out into the bottle line, and the whole process is over. The machine is equipped with automatic protection device. If there is a bottle bottle phenomenon, the machine will automatically stop to protect the safety of the human machine.

1. PLC fault PLC fault mainly has output point relay contact sticking.

If the motor is controlled at this point, the fault phenomenon is that after the motor is started, the motor runs, but after the stop signal is sent, the motor does not stop running. When the PLC is powered off, the motor stops running. If this point controls the solenoid valve. The fault phenomenon is that the solenoid valve coil is continuously powered and the cylinder is not reset. If you use an external force to strike the PLC to separate the glue points, you can help determine the fault.

There are two ways to repair the PLC output point fault. One of the more convenient ones is to modify the program with the programmer to modify the damaged output point to the alternate output point and adjust the line at the same time. If the 1004 point of the control solenoid valve is damaged, it is changed to the standby point of 1105 points.

The programmer can find the relevant statement of 1004 points, and keep(014)01004 is keep(014)01105. Control the motor's 1002 point damage, change to the standby point 1106, modify the 1002 point related statement out 01002 to out 01106, and adjust the line at the same time. If there is no programmer, you can use the second, more troublesome, remove the PLC, open the PLC and remove the output relay of the standby point to the damaged output point. Then install it according to the original line number.

2, proximity switch failure

The filling machine has five proximity switches. Three for knife protection and two for controlling the upper and lower film release motor. Among them, it is used to control the knife protection, and occasionally one or two mistakes. It will interrupt the normal operation process, and the number of failures is small and the time is short, which brings certain difficulties to the analysis and elimination of the failure. The cause of the failure is that the melt knife is in the process of descent. Did not encounter the packaged goods. When the melter is lifted close to the switch and loses the signal, the fuser automatically returns upwards as if it is in contact with the package. The fault repair method can install a switch of the same type in parallel with the proximity of the melt knife to the switch, and the two switches work in parallel to improve the reliability.

3, the magnetic switch failure

The magnetic switch is used to detect the position of the cylinder and control the stroke of the cylinder. The four cylinder actions of lamination, push pack, press pack and melt knife are interrelated and magnetic switches are used to detect and control their position. The main fault is that the subsequent cylinder does not move, because the cylinder speed is faster, and the magnetic switch cannot detect the signal. For example, if the speed of the push cylinder is too fast, the press pack and the melt knife cylinder will not operate after the push pack is reset.

4, solenoid valve failure

Solenoid valve failure mainly manifests as the cylinder does not move or does not reset, because the cylinder solenoid valve can not be reversed or helium. If the solenoid valve is suffocating, the air pressure of the machine will not reach the working pressure due to the communication between the inlet and outlet air lines, and the knives will not rise. The tool beam protection proximity switch does not work, the preconditions for full machine operation are not established, the machine cannot be operated, which is easily confused with electrical faults. There is a leaking sound in the solenoid valve helium. Listen carefully to the sound source and search for the leak point by hand. It is generally easy to find the solenoid valve of the helium gas. The repair method is to clean the solenoid valve and replace the damaged seal. If it is impossible to repair, replace the solenoid valve.

The above is the solution to the technical failure of the automatic filling machine. For example, if there is any doubt about the price, manufacturer, model and picture of the automatic filling machine, Shanghai Guangzhi, we will solve the difficulties encountered in the industry for you.
