  • Patent number: 11454567
    Abstract: The present disclosure relates to a fault diagnosis method of a reciprocating machinery based on a keyphasor-free complete-cycle signal. The method includes the following steps: 1) building a complete-cycle vibration signal image library; 2) training an image recognition model; 3) acquiring a complete-cycle data on a keyphasor-free basis; 4) building an automatic feature extraction model; and 5) inputting a hidden layer feature of an autoencoder into a support vector machine (SVM) classifier to obtain a diagnosis result. By using a deep cascade convolutional neural network (CNN), the present disclosure achieves the goal of complete-cycle data acquisition on a keyphasor-free basis, solves the problems that traditional intelligent fault diagnosis relies on a keyphasor signal and real-time diagnosis fails due to insufficient installation space. In addition, by using an autoencoder for automatic feature extraction, the present disclosure avoids manual feature selection, reduces labor costs.

  • Patent number: 11420461
    Abstract: The present invention relates to a drum stencil printing system for reliably and automatically printing materials on the inside of a concave surface. The drum stencil printing system includes a pliable drum stencil secured in place by a stencil spring. As the printhead applies radial pressure to the drum stencil, the portion of the stencil in contact with the printhead is deflected to make contact with the container sidewall. When the printhead rotates, the portion of the stencil contacting the container sidewall also rotates to match the nozzle of the printhead. After printing is complete, the printhead retracts, and the pliable stencil is returned to its undeflected position, breaking contact between the stencil and the container, and protecting the printed material from being rubbed or worn off of the container.

  • Patent number: 11413879
    Abstract: In an editing device, a controller is configured to perform: editing; and displaying. The editing edits print data for a composite label to be created by affixing at least one overlay label to a base label. A printer is configured to perform a single printing operation using an ink ribbon to print an object on a tape in a single printing color thereby creating a single label. The editing includes: determining a printing color of an object; categorizing the object to one of a base object and an overlay object; and setting a print mode to one of a shortest length mode in which a single overlay label is created for each overlay object and a fewest prints mode in which a single overlay label is created for all overlay objects having a same printing color. The displaying displays a composite label image based on the print data.

  • Patent number: 11396176
    Abstract: In a mask printing machine, a target through hole, which is at least one of multiple through holes formed on the mask, is imaged by an imaging device when the board is below the mask and is at a separated position that is separated from the mask, and when the board is at a contact position in which an upper surface of the board contacts a lower surface of the mask, respectively. Based on a captured image, when the board is at the separated position, and a captured image when the board is at the contact position, it is possible to acquire the movement state of at least one target through hole when the board is lifted from the separated position to the contact position.
