Sliding detection sensor system for automatic work feeding fixed dimension device (patent application)

奥村機械製作所

We are pleased to announce that Okumura Machinery Manufacturing Co., Ltd. has started publishing materials on a slip detection sensor system for automatic feeding and sizing devices. In gripping devices such as sizing machines, if the object being gripped slips during transport, it can lead to a decrease in cutting accuracy and handling performance, resulting in defective products and troubles. Therefore, we have jointly developed a sensor system with the Kagawa Prefectural Industrial Technology Center to detect slipping of the gripped object with high precision. This sensor features a unique structure that combines a parallel spring and a detection element, allowing it to detect and measure slipping within the gripping surface of the chuck, regardless of the shape or size of the gripped object. Additionally, by using two types of detection elements—a strain gauge and a piezoelectric film—we have enabled it to respond to both static and dynamic slipping. It can detect slips of workpieces on the order of 0.1 mm and employs the technology from our pending patent, Application No. 2022-92993.
