Food and Beverage Industry Capabilities
What is a two-piece can:
The two-piece tank is composed of two parts: the tank body (the tank body and the tank bottom) plus the tank cover. According to the processing technology, it is divided into a deep-drawing tank and a thinning and drawing tank. According to the material, it is divided into two-piece type. Steel cans and aluminum cans, two-piece cans are mainly used for canned beverages (such as cola, juice, black tea, green tea, etc.) and beer. The advantage of two-piece can packaging is that it is easy to carry, easy to open for drinking, and can be recycled without pollution.
Two cans production process:
Tank production process: cup punching - stretching forming - trimming - cleaning and drying - painting - printing - internal drying and spraying - necking and flanging - optical inspection - photographic inspection - packaging. The above production process can be divided into the front and back stages from the aluminum coil to the finished can body. Set up a buffer zone between the front and rear sections. When a certain piece of equipment fails, the front and rear sections can be repaired in sections, so as not to cause the entire line to stop production, thereby improving production efficiency.
Difficulties in the application of the transmission part:
The production process of two-piece cans is relatively long, and many motors and equipment are used, so there are problems of troublesome wiring and difficult maintenance.
Application of Rockwell automation products in two-piece cans:
PLC: 1756-L72 series CPU using AB high-performance, multi-tasking and multi-process.
Touch screen: 2711P touch screen with large storage capacity, Windows CE 6.0 operating system.
Drive products: According to the characteristics of the on-site use environment, AromrStart products that support ring network and high-performance PowerFlex750 series inverter products and PowerFlex525 series inverters. PF525 series inverter Rockwell PowerFlex525 inverter control, built-in Ethernet communication interface , Various motor control optional voltage-frequency ratio, speed sensorless vector control, closed-loop speed vector control. Various positioning controls PointStop, stop motor load at constant position without encoder feedback, closed loop feedback with optional encoder card, point-to-point positioning mode. Integrated PID function enhances application flexibility. PF750 series inverter has various control modes, standard V/Hz, with full customization function, speed sensorless vector control, with self-tuning function, flux vector control, with or without encoder feedback, induction and permanent magnet motor control . The cabinet adopts Hoffman FS66S stainless steel cabinet and PCF stainless steel field operation box, and the protection grade is IP66, which is the best choice for the cabinet in food and beverage.
Application characteristics of AromrStart in two-piece cans:
1. Save wiring, solve the problem of troublesome wiring and difficult maintenance.
2. Detachable control module, easier maintenance.
3. EtherNet/IP and DeviceNet are optional, and a ring network is formed by Hirschmann RS series switches, so that the network communication will not affect the production when it is interrupted at one point.
4. The protection level of up to IP67 makes the product more secure for on-site installation and use.
