Minebea Intec wins Patent of the Month
In May 2018, Hamburg Chamber of Commerce recognised a patent from Minebea Intec with its ‘Patent of the Month’ award. Patent number DE 10 2016 109 433 B4 describes a bolt sensor which allows bolt connections to be monitored remotely on bridges and at production facilities at risk of earthquakes for example. Patents like these are an important element of Minebea Intec’s research and development activities. They also play a key role in ensuring the company has a technological edge over its competitors.
2018年5月，德国汉堡商会授予将”本月专利”奖项授予了茵泰科的一项专利技术。此项DE 10 2016 109 433 B4号专利颁发给了一种螺栓传感器，它可以远程监测桥梁或者生产设施中螺栓的连接是否牢固。在处于地震等灾害性事故中，这样的远程监测非常有必要。专利技术是茵泰科的研发活动的重要组成部分，确保公司在竞争中保持技术领先。
Washers are normally used to distribute the force of a bolt head or a nut over a greater area. However, Minebea Intec’s patented bolt sensor can do much more than this when, for example, it is integrated in bridges and production facilities; the sensor is installed between the bolt head and the nut, thus providing a detection system for any problems relating to strength.
Security system relies on resistors and pressure
The innovative Minebea Intec bolt sensor is installed between the bolt head and the nut. Piezoresistive resistors are connected to the inside of the washer. At least one of the resistors is exposed to the pressure from the bolt head and/or nut, and at least one is not exposed to any pressure. As soon as the bolt connection becomes loose, due to an earthquake for example, the bolt sensor can immediately detect the damage thanks to the change in resistance, and a repair or shutdown can then be initiated. In this way, the bolt sensor becomes part of a security system that communicates dangerous defects in real time. Minebea Intec is now planning to develop a prototype based on the patent recognised by Hamburg Chamber of Commerce – the date for the market launch has not yet been set.
Patents secure an edge over the competition
Minebea Intec continuously invests in the research and development of new technologies and products. Through this the company continues to support its customers in optimising the safety, reliability and efficiency of their processes. The global manufacturer of weighing and inspection technologies registers between five and ten patents each year. The patents are of particular significance to the company as they ensure an edge over the competition, help maintain its brand value and guarantee the latest technology for the customer.
Proper validation in the ongoing process
A further patent from Minebea Intec, number DE 20 2016 103 037 U1, describes a special device for validating metal detection systems; this is known as ‘True In-Process Validation’. Metal detection is considered a critical control point within food production. The patent relates to the special area of ‘closed conveyor systems’. If, for example, a production process involves pumping cornflakes or hot marmalade using pressure, the patented True In-Process Validation enables validation to be carried out during the ongoing process. This is done by introducing the test piece using an applicator via a small opening above the search coil, directly into the centre of the product flow. As the centre of the conveyor tube represents the most difficult point to detect, this method guarantees reliable detection and documentation. Once introduced, the test media falls with the product through the search coil area. If the metal part contained within is detected, it is ejected via a separator. If it is not detected, a previously installed collection grid ensures that it is not transported onward with the ‘goods flow’. The invention has already been implemented by Minebea Intec, and has been offered as an optional extra with the freefall metal detection system Vistus since 2016. Minebea Intec has further patents, including rotationally symmetrical diaphragms and mounting kits for load cells, for example. More detailed information about Minebea Intec can be found at .
茵泰科的另一个专利DE 20 2016 103 037 U1，是用于验证金属检测系统的设备，称之为”真正的过程中验证”。在食品生产中，金属检测是一个关键点。这个专利涉及到了”封闭的传输系统”。特别是在例如使用压力泵送玉米片或热果酱的生产中，”真正的过程中验证”专利就能帮助在这种正在进行的过程中进行验证。通过进样器将测试片导入检测线圈中，直接进入产品流。传送管的中央是检测的难点，这种方法能确保可靠的检测和记录。测试片进入后与产品一同通过检测线圈，金属部分被检测到的话，会通过剔除器剔除。如果没有被检测到，事先安装的收集网格也能保证测试片不会随着产品流被放过。这个茵泰科的专利已经于2016年作为Vistus下落式金属检测系统的一个选项被投入市场。茵泰科的专利还包括传感器旋转对称隔膜和安装套件等。更多茵泰科的信息，请访问.
