1. Industry Analysis- Rice Packaging Line
At the inner vacuum packaging process end of the rice packaging equipment, the process covers a number of delicate steps such as material conveying, vacuuming, and sealing. Through vacuum packaging, it can effectively exclude the air inside the rice packaging bag, inhibit the growth of microorganisms, extend the shelf life of rice, and at the same time prevent the rice from deteriorating due to oxidation and moisture during storage and transportation, so as to maintain its taste and nutrient content.
However, with the development of the industry, rice packaging equipment in actual operation has gradually exposed some pain points.
2. On-site Pain Points- MTC Series Valve Island is Easy to Solve
Traditional rice packaging equipment program, in the long-term operation, problems gradually appeared.
Question 1：Poor Stability
Equipment in the packaging of rice will produce continuous vibration, the external wiring type valve island used in the traditional program, after a long period of vibration, the solenoid valve wiring parts are prone to failure, which will lead to the cylinder can not be normal action, and ultimately lead to equipment shutdown, seriously affecting production efficiency.
1 . Adopting down-plug wiring design, the solenoid valve is firmly fixed with the base through the fastening screws.
2. After a large number of harsh vibration experiments to verify that in the vibration environment of the equipment, to ensure the stable operation of the solenoid valve, effectively avoiding the wiring failure caused by vibration, to provide a solid guarantee for the continuous and stable operation of the equipment.
The overall layout of the rice packaging equipment is compact, covering a small area, but its degree of automation is high; a large number of sensors and actuators are distributed in all parts of the equipment, requiring fifty to sixty I/O points. In the traditional solution, the I/O modules are all installed in the electrical cabinet, and the wiring of the sensors in each corner of the equipment is extremely cumbersome, which not only consumes a lot of manpower and time but also is not conducive to the maintenance and management of the equipment.
Question 2:Complex Layout, Cumbersome Wiring
The overall layout of the rice packaging equipment is compact, covering a small area, but its degree of automation is high; a large number of sensors and actuators are distributed in all parts of the equipment, requiring fifty to sixty I/O points. In the traditional solution, the I/O modules are all installed in the electrical cabinet, and the wiring of the sensors in each corner of the equipment is extremely cumbersome, which not only consumes a lot of manpower and time but also is not conducive to the maintenance and management of the equipment.
The traditional program uses several sets of valves in the lower corners of the rack for the overall lifting of the rack and pneumatic vibrator control, respectively.
1. With an integrated I/O function, it can replace the original cabinet I/O. When the valve island with I/O module is installed on the equipment, the sensors can be connected to the I/O points of the valve island, and there is no need to pull the cables to the electrical cabinet, which greatly optimizes the overall wiring layout of the equipment, and reduces the cost of wiring and the difficulty of maintenance.
2. The pressure partition and exhaust partition functions of the MTC series valve island can integrate the original four sets of valves into one set. Through the pressure partition, it can provide high pressure for the rack lifting cylinder to meet its working demand; meanwhile, through the exhaust partition, it effectively avoids the pneumatic vibrator malfunction triggered by the excessive exhaust volume during the fall of the rack cylinder, and simplifies the structure of the equipment’s air circuit.
3. Decowell Program-Project Configuration
The customer’s original program adopts an external wiring manifold program, due to the presence of equipment vibration, rice splash phenomenon, there is a risk of solenoid valve control failure. After the customer adopts our MTC series valve island, the main advantages are as follows:
1. Modular assembly of equipment: With the integrated I/O characteristics of the valve island, the assembly mode of equipment can be optimized.
The equipment frame is processed by the outsourcing factory, and the electrical cabinet and program are provided by the partner. The valve island can be divided into three small cabinets and pre-assembled in advance. Once all materials have been prepared, only the cylinders, sensors, and other components need to be installed and wired in the factory.
This modularized assembly method greatly shortens the assembly cycle of the equipment and improves the production efficiency; the down-plug solenoid valves are connected solidly and reliably, reducing the risk of failure.
2. Line layout optimization: all sensors can be wired nearby, changing the previous complex wiring. This not only saves a lot of labor and reduces wiring costs, but also improves the overall aesthetics of the equipment.
At the same time, the optimized wiring layout is more convenient for the daily maintenance and troubleshooting of the equipment, which provides strong support for the stable operation of the equipment. In addition, the solenoid valve can do pressure zoning, in the same set of valve islands, to achieve two different gas supply pressures.
