Abstract: A combination weighing device is provided that discharges, from a hopper, an article oversupplied into and received by the hopper and that collects the article using the collection container. The combination weighing device includes an oversupplied article retainer disposed at a position on a discharge path for the article to be discharged from the hopper and collected by the collection container. The oversupplied article retainer has a collection chute and a blocking shutters and temporarily retains the article guided to flow downward using the collection chute and the blocking shutter.

Abstract: A combination weighing apparatus includes a retaining hopper that retains an article and supplies the retained article onto a transport path. The retaining hopper has a coupling portion adapted to be inserted in along the support rails and pulled off from support rails disposed in a pair. The retaining hopper is thus supportable by the support rails and is readily mounted to and dismounted from the apparatus without using any tool for cleaning and other purposes.

Abstract: A linear feeder is provided that vibrates a trough to transport articles on the trough. The trough has a guiding protrusion at an intermediate position on a bottom surface of a transport path in a direction of its width. The guiding protrusion is progressively greater in lateral width in a direction of transport of the articles, and transport passages progressively smaller in width are accordingly formed at sides of the guiding protrusion.
