リボンスリッターの「効率革命」

This "revolution" is not triggered by a single technological breakthrough, but a comprehensive evolution around intelligence, automation, high precision and digitalization. Its core goal is to produce ribbon products with more stable quality and higher consistency with less manpower, lower losses, and faster speed, so as to meet the challenges of diversified market demands, rising labor costs, and extreme quality requirements.

Here are a few key dimensions of this "efficiency revolution":

1. Intelligence and automation: a leap from "human control" to "intelligent control"

Traditional slitting machines are highly dependent on the operator's experience, and efficiency and quality fluctuate greatly. Modern slitting machines realize intelligent control of the whole process.

• Automatic tool change system:

◦ Revolutionary: Traditional slitting requires stopping the machine to manually adjust the tool holder, which is time-consuming, labor-intensive and error-prone. Automatic tool change system Through the central control system, the slitting scheme (width, number of turns, etc.) can be entered with one click, and the tool holder can be moved to the specified position automatically and accurately.

◦ Efficiency improvement: The tool change time is shortened from a few minutes or even tens of minutes to tens of seconds, realizing rapid changeover, especially suitable for small-batch, multi-variety order production.

• Automatic Dressing System:

◦ Revolutionary embodiment: Ribbon dressing, especially thin materials, is a job that requires patience and skill. The automatic dressing system automatically pulls the material through the entire slitting path with a single button through a series of guide rollers, sensors and pneumatics.

◦ Efficiency Improvement: Significantly reduces the reliance on skilled operators, reduces dressing time, and avoids material waste and damage caused by manual operation.

• MES/ERP System Integration:

◦ Revolutionary: Slitting machines are no longer information silos. It can connect with manufacturing execution systems (MES) or enterprise resource planning (ERP) systems to automatically receive production orders and process parameters, and upload production data (e.g., yield, downtime, loss rate) in real time.

◦ Efficiency Improvement: Seamless connection of production planning and automation of data flow are realized, providing the foundation for lean production and digital management.

2. High precision and high quality: Pursue "zero defect" slitting

Efficiency cannot be improved at the expense of quality, and modern slitting machines have achieved the ultimate in precision.

• 高精度張力制御システム：

◦ Revolutionary embodiment: Adopt full closed-loop servo tension control to maintain constant and accurate tension throughout the whole process from unwinding, traction to winding. The system monitors and fine-tunes in real-time to respond to tension fluctuations caused by changes in material diameter.

◦ Efficiency improvement: The extremely high tension control avoids problems such as material stretching, wrinkling, and serpentine deviation, greatly reducing the scrap rate and improving the "one-time success rate" from the source, which is the maximum efficiency.

• Online visual inspection system:

◦ Revolutionary embodiment: Integrated high-resolution CCD camera to detect the presence of defects on the ribbon surface in real time, such as scratches, particles, bubbles, printing defects, etc., during the high-speed slitting process. Defects can be automatically flagged or alarmed.

◦ Efficiency improvement: Achieved 100% full inspection, replaced manual sampling inspection, avoided defective products from flowing into the hands of customers, reduced quality claims and returns, and improved brand reputation.

• Electrostatic equipment and dust removal systems:

◦ Revolutionary embodiment: Carbon strips are prone to generate static electricity during slitting, absorbing dust and affecting product cleanliness. Modern slitting machines integrate ion air rods, electrostatic brushes and other devices to effectively eliminate static electricity, and are equipped with a vacuum suction system to keep the material clean at all times.

◦ Efficiency Improvement: Ensures high cleanliness of the product, meets the stringent requirements of high-end applications such as electronic label printing, and reduces customer complaints due to cleanliness issues.

3. High speed and high stability: let the machine "never stop"

• Direct drive servo technology:

◦ Revolutionary embodiment: each main roller (unwinding, unwinding, traction roller) is directly driven by independent servo motors, abandoning the complex mechanical transmission structure.

◦ Improved efficiency: higher transmission efficiency, faster response, more precise control, lower noise, and simpler maintenance. It realizes stable operation at high speeds, and the mechanical speed can reach 600-800 m/min or even higher.

• Dual Station Rewinding/Unwinding:

◦ Revolutionary: Equipped with two unwinding and two rewinding axes, while one station is running, the other station can be ready for loading and unloading.

◦ Efficiency improvement: Continuous production without downtime is realized, eliminating downtime for changing raw material and finished rolls, and greatly improving the overall equipment utilization rate (OEE).

4. Human-computer interaction and data analysis: Make decisions "evidence-based"

• Large touchscreen HMI:

◦ Revolutionary embodiment: Graphical human-machine interface, intuitive and simple operation. It can store hundreds of product slitting parameter recipes and call them with one click.

◦ Efficiency improvement: Reduces operation difficulty and training costs, and avoids human setting errors.

• Data Traceability and Analysis:

◦ Revolutionary: The machine automatically records all key data for each slitting job: time, operator, material batch, slitting parameters, output, losses, etc.

◦ Efficiency improvement: By analyzing historical data, the slitting process can be continuously optimized, equipment maintenance needs can be predicted, and continuous improvement and scientific management based on data can be achieved.

Summary: The ultimate embodiment of the efficiency revolution

The results of the "efficiency revolution" of ribbon slitting machines are ultimately reflected in the following key indicators:

1. Significantly improved OEE (Overall Equipment Efficiency): Maximize the effective output of equipment by reducing downtime (tool change, material change), increasing operating speed, and reducing scrap rates.

2. Significantly increased per capita output: Automation reduces the reliance on manual labor, allowing one operator to manage multiple devices simultaneously.

3. Significant reduction in comprehensive costs: material loss, energy consumption, labor costs, and quality costs are reduced simultaneously.

4. Faster market response: It can quickly and economically complete small batches and multi-variety orders, enhancing the market competitiveness of enterprises.

This revolution has changed ribbon slitting from a "craft" to a "science", which is a typical epitome of Industry 4.0 intelligent manufacturing and is continuing to promote the development of ribbon and related industries.
