Customer demand and environmental awareness are driving consumer packaged goods (CPG) companies to significantly reduce their carbon footprint. Monitoring the pneumatic components in the packaging production line to save a lot of energy is a desirable way.
Automated operations in the packaging machinery industry are changing the way the packaging process works and the processing methods of packaging containers and materials. A complete automatic packaging machine is composed of many components, among which arm-end operating tools, material transport devices and identification and verification systems are the main components. In packaging applications, the end effector is usually designed as a vacuum sleeve that can be used directly, a clamping jaw, or a combination of the two. These include power transmission belts, monorail cranes, automatic guided vehicles and manipulators. The automatic packaging production line is composed of automatic packaging machines, auxiliary equipment and conveying devices in a certain order according to the product packaging process, and then equipped with corresponding detection, control, and automatic adjustment and compensation devices.
The pneumatic system is mainly composed of air source processor, pneumatic solenoid valve, one-way throttle valve, air cylinder actuator, air cylinder and various pneumatic connectors and pipelines. The cylinder speed is adjusted by a one-way throttle valve. The output cylinder is equipped with a magnetic switch, and other large-bore cylinders are not equipped with a magnetic switch. Therefore, the starting position of each mechanism is equipped with a proximity switch, which can send a signal to instruct the next action through the program, and automatically complete the whole process of the whole machine action.
In the pneumatic control system, the pneumatic generating device is generally an air compressor, which converts the mechanical energy supplied by the prime mover into the pressure energy of the gas. The compressor referred to here includes single cylinder air compressor, double cylinder air compressor and three cylinder air compressor. Pneumatic actuators convert pressure energy into mechanical energy to complete prescribed actions.
Between these two parts, various control elements (pneumatic cylinder control valve, pressure control valve, pneumatic cylinder flow control valve, directional control valve, and logic element) and transmission are transferred in a certain order according to the requirements of the working cycle of machinery or equipment. The sensing element and the pneumatic accessories are connected.
In order to achieve high-precision dynamic weighing in the production line, the hopper is designed with a three-way blanking device. There are three large, medium and small gates installed at the bottom of the weighing machine's storage bin, and three solenoid valves are respectively controlled by three cylinders to complete the opening and closing of the large, medium and small gates. Other compact air cylinders respectively control the opening and closing of the weighing hopper door, the printing of the printer, the cutting off of the seal of the horizontal sealer, and the evacuation of the electric heating plate.
In the automatic packaging machine, the air source treatment must supply the compressed air to the pneumatic device. In addition to ensuring its pressure and flow, it must also remove the oily sewage and dust in it to reduce the wear of the pneumatic components and avoid the corrosion of its parts. Otherwise, this will cause the system's work efficiency to decrease, and often cause malfunctions and accidents. When necessary, a pressure relay and the electrical part of the host should be interlocked. Secondly, in order to meet certain operational requirements, various control components are often concentrated in the control box. Pneumatic devices in the packaging industry include air piston cylinder and compact pneumatic cylinder.
