A combination weighing apparatus having excellent sanitation includes: a plurality of weighing mechanisms, a weighing mechanism frame which stores the weighing mechanisms, and a body frame which supports the weighing mechanism frame, in which a normal to a surface of the body frame is inclined with respect to a vertical direction.

Support structure for a combination weighing device

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.

Multihead weigher

A combination weighing device facilitates the performance of operation using optimal operational settings. The combination weighing device includes a dispersion feeder, a plurality of radial feeders and a plurality of weighing hoppers. The dispersion feeder is disposed in an upper portion, and conveys and disperses supplied articles. The radial feeders are arranged radially on the periphery of the dispersion feeder, and convey the articles that are discharged from the dispersion feeder. The weighing hoppers receive the articles discharged from the radial feeders. The combination weighing device performs a combination weighing based on the weight of the articles in the weighing hoppers. In the combination weighing device, the operational settings are performed automatically.

Combination weighing device initialization

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. The parameter operation part operates a control parameter so that the transport quantity per group transported by the radiation feeder reaches a target introduction value if the transport quantity per group transported by the radiation feeder is stable, while operating the control parameter so that the transport quantity per group transported by the radiation feeder is not in excess of a target measured value if the transport quantity per group transported by the radiation feeder is dispersed. The combinational measuring device controls driving of the radiation feeder on the basis of the obtained control parameter. Thus, it is possible to provide a combinational measuring device performing efficient measurement.
