  • Publication number: 20200404819
    Abstract: The attachment possible period during which the attachment operation of the component supply reel can be performed is predicted for each of the tape feeders equipped in the component mounting apparatus, and the attachment time indicating a timing of the attachment operation is set to overlap the attachment possible periods of the candidate feeders, out of the tape feeders. Therefore, a frequency of the component replenishment operation of the operator can be suppressed. Further, the execution mode of the attachment operation for the candidate feeder corresponding to the attachment time is determined based on the number of the components planned to be supplied in accordance with the production planning by the candidate feeder. Therefore, a number of the components suitable for the production planning of the components-mounted boards can be replenished.

  • Patent number: 10248072
    Abstract: A cleaning roller includes a shaft and an elastic body. The shaft extends in an axial direction where a center axis of the shaft extends. The shaft defines a radial direction and has a circumferential surface. The elastic body is helically wound about the shaft and defines a helical direction. The elastic body has a widthwise dimension in a widthwise direction orthogonal to the helical direction and to the radial direction. The elastic body has a base end portion extending in the helical direction and a distal end portion extending in the helical direction. The base end portion is in contact with the circumferential surface and fixed thereto. The distal end portion has a sharp edge and is positioned farthest from the circumferential surface in the radial direction. The widthwise dimension is gradually reduced from the base end portion to the distal end portion in the radial direction.

  • Patent number: 9952551
    Abstract: An image forming apparatus includes a photosensitive member, a charger, a developing device, a transfer device, a scraper, and a controller. The controller performs an image formation process to form the developer image on the photosensitive member by using the developing device. The controller acquires, as a first value, at least one of a value of the charging current flowing in the charger and a value of the transferring current flowing in the transfer device. The controller calculates an accumulation current value by using result of an integral of a second value over time. The second value is an absolute value of the first value. The controller performs a scraping process in which the scraper scrapes the photosensitive member when the accumulation current value reaches a threshold value.
