Patent number: 9417115Abstract: A combination weighing device includes a dispersing table, a plurality of radial feeders, a plurality of cameras, an image processing unit, and a touch panel. The dispersing table receives a supply of a large number of articles and disperses the articles. The radial feeders are arranged to extend radially from the dispersing table, receive the articles dispersed by the dispersing table, and convey the articles in a direction away from the dispersing table. The cameras are disposed at a position other than a space directly above the dispersing unit and capture images of the dispersing table and the radial feeders. The image processing unit generates a projection plan view image of the dispersing table and the radial feeders by synthesizing the images captured by the cameras. The touch panel outputs the plan view image.Type: GrantFiled: February 20, 2013Date of Patent: August 16, 2016Assignee: ISHIDA CO., LTD.Inventors: Yutaka Tamai, Hideshi Miyamoto

Patent number: 7064281Abstract: A combinational measuring device is provided with a radiation feeder transporting objects and a measuring hopper measuring the weight of each group of objects transported by the radiation feeder. As to each measuring hopper performing introduction by a prescribed frequency, an average operation part obtains an average and standard deviation of a transport quantity every group transported by the radiation feeder. On the basis of the obtained standard deviation, a parameter operation part determines whether or not the transport quantity per group transported by the radiation feeder is dispersed.Type: GrantFiled: November 20, 2003Date of Patent: June 20, 2006Assignee: Ishida Co., Ltd.Inventors: Toshiharu Kageyama, Takumi Kawamura, Yutaka Tamai
