Delta 4-Axis Motion Control Solution Enhances Production Efficiency for Medicine Reciprocating Packaging Machine

Along with economic development, social advancement, and an aging population, concern for human health issues has gradually increased. This trend drives the rapid development and growth in the pharmaceuticals market, and the pharmaceutical industry has become focused on value-added worldwide. In Asia, especially China, Taiwan, Singapore, and Korea, the demand for health care and pharmaceuticals has dramatically increased due to rapid economic development, bringing growth to pharmaceutical equipment and the supply chain as well. New drug development costs have increased while revenue growth has decreased due to limited medical expenses in recent years. The pharmaceutical industry is facing an industry consolidation, as well as the challenges of production upgrades.

In Wenzhou, China, a packaging equipment manufacturer cooperated with Delta to implement Delta's 4-axis motion control solution to a medicine reciprocating packaging machine. With Delta's solution, the overall speed, efficiency and precision of the packaging machine were greatly enhanced. The manufacturer was delighted to have more highly efficient machines to satisfy customers.

The medicine reciprocating packaging machine is mainly applied to bag making, bag sealing and date/barcode printing. To satisfy user needs, the manufacturer also added automatic material discharging and feeding processes to the machine.

Delta responded to customer requirements and provided a 4-axis motion control solution. The solution included Delta products such as the:

• HMI DOP-B Series for operation control, parameter setting, and machine monitoring interface
• 3-Axis Synchronous Servo Drive ASDA-M Series for motor control of material feeding, film feeding, and horizontal pack cutting processes
• Advanced Servo Drive ASDA-A2 Series for drive and control of material discharge process
• Temperature Controller DTE Series to monitor the pack sealing temperature, ensuring that the machine doesn't overheat during processing

The ASDA-M Series has built-in motion control and PLC functions, and features 3-axis synchronous control to perform material feeding, film feeding and rotary cutting at the same time. The ASDA-A2 Series conduct precise and high speed control for the material discharge process.

With Delta servo drives' built-in E-Cam function and high-speed motion network system DMCNET for communication, the medicine reciprocating packaging machine features highly precise positioning (±1mm) and high communication speed (10Mbps), to achieve high production efficiency with a packaging speed of up to 150 bags per minute.

The manufacturer successfully enhanced the operation speed and precision of the medicine reciprocating packaging machine with Delta's solution. Using production machines of high quality and high efficiency they won their customers' confidence. Delta's motion control solution can also be applied to food and other packaging machines for machinery upgrades in a range of industries.
