  • Publication number: 20220145985
    Abstract: An abnormality of a gear is more appropriately predicted. An abnormality prediction device of the present disclosure is used in a feeding device including a driving section, a gear connected to the driving section, and a detection section configured to detect a position of a medium fed in accordance with driving of the gear, and intermittently feeding the medium. The abnormality prediction device acquires detection information regarding a feed amount of the medium based on the position of the medium detected over time by the detection section, decomposes the acquired detection information into a trend component regarding a moving average of the gear, a cycle component based on a cycle of the gear, and a random component obtained by excluding the trend component and the cycle component, obtains an abnormality level of the gear based on the cycle component obtained by the decomposition, and outputs the obtained abnormality level.

  • Patent number: 10772250
    Abstract: Component mounting system 1 includes electronic component mounting device 10, control device 100, image processing device 110, memory device 115, and display 120. Electronic component mounting device 10 includes mounting head 26, supply device 28, and component camera 90, and is configured to use mounting head 26 to pick up an electronic component supplied by supply device 28 and to image the held electronic component using component camera 90. When saving the captured image data on memory device 115, it is determined whether a condition for using a first format is satisfied (S1, S2). When the conditions for using the first format are satisfied (S2: yes), the captured image data is saved on memory device 115 in the first format that is a lossless compression format (S5). When conditions for using the first format are not satisfied (S2: no), the captured image data is saved on memory device 115 in the second format, which is a lossy compression format.
