Automatic rotary type PLC base sticker labelling machine (star wheel mechanism) by AARVI engineering An advanced piece of machinery utilized in high-speed production lines, an automatic rotary sticker labelling machine with a star wheel mechanism and PLC-based control is mostly used for marking round bottles or cylindrical containers. A PLC (programmable logic controller) and the star wheel mechanism work together to guarantee that the machine runs effectively, precisely, and automatically. The star wheel is a mechanical component that precisely and circularly turns and arranges bottles or containers. As the bottles pass through the system, they are safely held in place by specially constructed pockets or slots. The labeling machine's operations are automated and controlled by a PLC (Programmable Logic controller). The PLC incorporates a number of machine components, including: Bottle placement Label positioning Control of speed The labeling head and star wheel synchronization By modifying variables like speed, label alignment, and timing for best results, the PLC allows the machine to run independently. Additionally, it makes real-time monitoring and diagnostics possible, which improves operational effectiveness. Interface with Touchscreen: Operators may easily configure parameters, troubleshoot, and monitor the system via the machine's user-friendly touchscreen interface, which is usually connected to the PLC.
