  • Patent number: 11192136
    Abstract: To provide a powder resin coating method and powder resin coating device which can maintain a powder surface as flat irrespective of changes in the average particle size of powder resin. A powder resin coating device (1) includes a powder fluidizing bed (2) storing powder resin, a vibration mechanism (5) connected to the powder fluidizing bed (2), and a control device (8) controlling the frequency of the vibration mechanism (5). The control device (8) includes an average particle size estimation unit (82) that estimates the average particle size of powder resin stored within the powder fluidizing bed (2); an optimum frequency determination unit (83) that determines an optimum frequency for causing the powder surface to flatten based on the average particle size estimated by the average particle size estimation unit (82); and a frequency control unit (84) causing the vibration mechanism (5) to vibrate at the determined optimum frequency.

  • Publication number: 20200300741
    Abstract: A flow inspection method includes: a flow step of making powder resin flow in a housing portion of a flow tank; a viscosity measurement step of measuring a viscosity of the powder resin flowing in the housing portion; and a judgment step of judging whether or not an estimate of a bulk density of the powder resin flowing in the housing portion is less than or equal to a bulk density permissible value, the estimate being obtainable from a correlation, calculated in advance, between the bulk density and a viscosity of the powder resin flowing in the housing portion, and a measured value of the viscosity obtained in the viscosity measurement step.

  • Publication number: 20190301917
    Abstract: First to eighth laser measurement sections (30a) to (30h) of a laser measurement unit (30) measures a height of a surface of powder resins (15) in a coil insertion range CA for every angular degree in a circumferential direction of a stator core (2). A control unit (18) computes the number of points where the height of the surface is lower than a predetermined height among measurement results at multiple points measured by the first to eighth laser measurement sections (30a) to (30h), where the number of points is defined as an index value indicative of a dispersion of the measurement results. When it has been determined that the index value exceeds a first predetermined value, a notification is issued by outputting from a speaker (32) a sound indicative of the fact that the index value that has been computed exceeds the first predetermined value.

  • Patent number: 9550275
    Abstract: A disc-shaped grindstone 1 includes a plurality of split grindstones provided in an outer circumferential surface of a disc-shaped base 3. At least a part of the split grindstones include a moving grindstone 6 which is movable in the axial direction of the disc-shaped base 3. Since a part of the split grindstones 4 is the moving grindstone 6 which is movable in the axial direction, the width of the disc-shaped grindstone 1 may be changed in a manner such that the moving grindstone 6 is moved in the axial direction. Accordingly, it is possible to promptly handle a plurality of kinds of grinding targets without replacing the disc-shaped grindstone 1.
