Automatic bag openers are industrial equipment specifically designed for the automated unpacking of packaging materials, widely used in industries such as chemicals, food, pharmaceuticals, building materials, and metallurgy. Their core function is to rapidly and efficiently open various types of packaging (such as woven bags, paper bags, plastic films, etc.) through mechanical or pneumatic means, and to release the internal materials (powders, granules, flakes, etc.) without damage to downstream conveying or processing systems. The equipment controls functional modules—including bag breaking, conveying, screening, and dust collection—via PLC, significantly improving production efficiency while reducing dust pollution and material waste associated with manual bag opening.

A equipment manufacturer has designed multiple models of automatic bag openers, with products sold across the country and widely distributed. The traditional model of relying on onsite manual inspections and aftersales service visits by traveling technicians faces challenges such as high operation and maintenance costs, delayed fault response, and insufficient data analysis capabilities.

To address this, it is now required to collect PLC data from automatic bag openers deployed nationwide and consolidate it into a unified equipment operation and maintenance management platform, enabling remote monitoring and intelligent management of the equipment. WideIOT deploys industrial IoT gateways to connect to the PLC controllers of various automatic bag opener models, collecting realtime equipment operating status and key process parameters. The data is uploaded to the cloudbased operation and maintenance management platform via 5G/4G networks, enabling functions such as equipment status monitoring, fault alerting, remote operation and maintenance, and data statistical analysis. This helps the equipment manufacturer reduce aftersales service costs, improve service response efficiency, and achieve digitalized and intelligent management throughout the equipment lifecycle.

Functional Capabilities

Collects key operating parameters of automatic bag openers, including the operating status of the bagbreaking device, conveyor motor current and rotational speed, screening machine vibration frequency, dust collector fan start/stop status, and material level, with intuitive visualization through graphical HMI dashboards.

Supports permission management and remote operations. Management personnel can send commands to PLCs of remote equipment via the monitoring platform or mobile terminals, enabling remote start/stop of equipment, adjustment of operating parameters, and switching of working modes, thereby improving emergency response capabilities.

The system automatically detects equipment anomalies based on preset rules and sends realtime alerts to relevant personnel via SMS, WeChat, email, and other channels, helping maintenance technicians quickly locate issues, shorten fault repair time, and reduce equipment downtime.

When equipment malfunctions, remote engineers can securely access the onsite PLC control system through remote maintenance channels to perform remote upload/download of PLC programs, online programming and debugging, and firmware upgrades. This significantly reduces the frequency of business travel and improves aftersales maintenance efficiency.

Generates multidimensional analytical reports and trend charts based on historical equipment operation data—covering equipment operating efficiency, fault frequency, maintenance work order completion rates, and more. This helps the equipment manufacturer understand the operational health and energy efficiency levels of each model, providing a scientific basis for product R&D improvements, aftersales service optimization, and spare parts inventory management.
