Rotating Torque Sensors for Capping Medicine Bottles
Robust and wireless sensors for a high speed and sterile operation
旋转的扭矩传感器在邓迪轴丝网的领先医疗测试套件中起着至关重要的作用，该测试套件开发了新的诊断化合物，有助于早期识别和管理重症疾病。
这companyAxis-Shieldis a world leader in inventing new markers for identifying cardiovascular and neurodegenerative diseases, rheumatoid arthritis, sepsis, vitamin deficiencies and diabetes. Spotting early signs of such conditions during routine medical check-ups means treatment can be started in a timely manner, which leads to improved patient management, either curing or managing the problem.
这compounds it develops are initially produced in low volumes, where automated processes are not appropriate. This moves to medium volume production once the product has been proven, approved and certified and the medical fraternity begin using it.
后来有些化合物转入大量生产，但在医学进步的本质上，轴屏幕将继续改善配方并相当快地开发新产品。因此，Axis-Shield需要高效的中型包装解决方案，以确保对性能参数的准确和一致的遵守。
正确的扭矩
这导致轴屏幕委托定制包装系列，该系列可以以每小时约500-2500台的速度以各种不同的包装格式处理多种产品。该生产线将瓶子或其他形式的容器填充化合物，帽子盖，标记它们，将它们分组为多包装，应用外套和夸张的关键数据，例如生产日期，使用日期，存储，处理和使用说明，处理，处理和使用说明，等等
该公司的迪恩·哈珀（Dean Harper）解释说：“限制瓶子是该过程的关键部分。”“我们的线可以与两种尺寸的帽子一起使用，并且必须将每个尺寸拧紧到正确的扭矩，以在相当紧的公差内。”
强大的扭矩传感器：高速和非接触操作
这ORT 230/240旋转扭矩传感器is unlike any other sensor in that it does not rely on delicate slip rings to transmit torque readings. It does thiswirelessusing radio signals transmitted from a pick-up located near to, but not actually contacting the rotating drive shaft of the capping mechanism.“The capping process is essentially simple,” says Dean, “but you have to allow for a fast cycle time and the need to guarantee torque while ensuring total sterility.”
这Rotating Torque Sensor符合鲁棒性，简单的高速操作和无菌性无接触的设计标准。我们合作伙伴传感器技术的马克·英厄姆（Mark Ingham）提供了细节：“ORT 230/240旋转扭矩传感器是此应用程序的理想选择；我们只需要制定安装安排即可。我们向传感器提供了Torqview软件，这些软件既可以实时显示读数，又要归档它们应该分析或跟踪和跟踪是应用程序的要求。
Wireless Monitoring
Being wireless, the Rotating Torque Sensor does not need to physically contact the bottle caps or shaft of the torque head it is monitoring. Instead, sensing is achieved through a radio frequency link using Surface Acoustic Wave (SAW) sensors. A shaft twists very slightly when it rotates, the amount of deformation being proportional to the torque. The Torque Transducer measures the deformation so that it can calculate torque. To do this two tiny piezoelectric combs (SAW sensors) are glued to the surface of the shaft at right angles to one another; shaft deformation will expand one comb and compress the other. A radio frequency signal emitted by the Rotation Torque Sensors is reflected back by the combs, with its frequency changed in proportion to the combs' deformation.
For Axis-Shield, the software was required to do two things: run the torque up to a set level within tolerances, and record the actual value achieved. This secures the cap to the bottle at a level of tightness that will ensure security and sterility, yet is at a level that can be opened relatively easily by an adult. The logged values are saved to a hard drive to provide a permanent record for traceability purposes.
Dean explains: “Diagnostic fluids are distributed widely, often globally, so they may be stored for months before use. Tracing each bottle’s origin would be practically impossible without full records being automatically produced and saved to a central location.”
