Delta Motion Control Solution Delivers Precise and Reliable Application for Adhesive Bandage Packaging Machine

Over time as living standards increase, the requirements for product packaging quality and appearance also grow. Packaging vendors have developed various new and practical packaging machines and technologies that cater to different packaging styles, materials and processes. Of these, adhesive bandage packaging machines are a special application of multi-axes packaging machines that combine adhesive materials, cotton pads, and outer packaging. To comply with medical standards, an adhesive bandage packaging machine provides a complete one-time packaging operation with strict requirements for precise cutting and efficient operation.

To fulfill the need for precise packaging and cutting, Delta provides packaging machine manufacturers with an adhesive bandage packaging machine solution based on Delta's motion control system. This solution uses Delta AC Servo Drive & Motor ASDA-M Series as a master motion control for controlling the packaging cutter axis, profiling the cutter axis, and dressing the pad cutter axis synchronously. Via Delta's DMCNET communication protocol, it connects the other 4 AC servo systems while adopting the Delta AC Servo Drive & Motor ASDA-A2 Series, controlling the packaging traction axis, profiling the traction axis, dressing the pad traction axis and punching the axis respectively to achieve the goals of precise cutting control and highly efficient production. With the Human Machine Interface DOP-B Series, users can set up parameters and monitor the production and machine operation, ensuring that the adhesive bandage packaging process completes smoothly.

In actual application, Delta's adhesive bandage packaging machine solution brings the following benefits to our customers:

• Precise and strong control system: The adhesive bandage packaging machine consists of 7 axes. It adopts the Delta AC Servo Drive & Motor ASDA-M Series for 3-axis control and as main controller. The ASDA-M Series features a built-in E-CAM and PLC to control 3-axes synchronously. The ASDA-Soft configuration software offers flexible setting for switching the master and slave axes to achieve an accurate multi-axis cutter operation. The ASDA-M Series and the ASDA-A2 Series controlling the other 4-axes all feature a full-closed loop function, reducing the effects of backlash and vibration from the machine and ensuring the accuracy of positioning. The ECMA series servo motors feature incremental encoders with 20-bit resolution which can position cutters accurately for the cutting process. They also support a 17-bit absolute system. The position of motors is maintained when the power is off, and accurate packaging performance can be continued when the operation begins again.

• Real-time monitoring with HMI: The adhesive bandage packaging machine integrates Delta's 10.1-inch Widescreen HMI DOP-B Series. The DOP-B Series' full 65,536-color LED screen provides a realistic image display. Users can set up parameters of the machine and monitor the production and operation status of the machine easily with the HMI. The DOP-B Series is equipped with an audio output interface. In case of errors, an alarm alerts users via an audio message in real time to prevent delays in operation and packaging efficiency. The DOP-B Series supports RS-232/485/422 communication interfaces and easily connects to various industrial automation devices for a complete monitoring network.

• Fast and efficient solution: Delta applies its motion control system to the 7-axis adhesive bandage packaging machine, connecting the axes with Delta's real-time communication protocol DMCNET. DMCNET's max speed is 10Mbps. It is capable of controlling up to 12 axes of servo system units to simplify wiring and save cost between the axes. DMCNET is able to deal with commands of the servo motors, or up to 768 points DI and 768 DO data within 1ms simultaneously. The adhesive bandage packaging machine integrated with Delta's motion control system can achieve up to 1,200 pcs/min operation speed with an accuracy within ±0.5mm, fulfilling customer's requirement for accurate and efficient adhesive bandage packaging.

Delta's adhesive bandage packaging machine solution fulfills customer's expectations for an accurate and efficient packaging machine. Delta continues to offer comprehensive solutions to meet our customer's diverse requirements, and to ensure an outstanding future together.
