Abstract

PROBLEM TO BE SOLVED: To facilitate cleaning without storing a dirt dropping from a conveyor. SOLUTION: In the metering apparatus comprising a weighing conveyor 1A, an entrance conveyor 1B on a series of conveying routes to convey articles, and a metering unit 8 arranged at a lower side of the conveyor 1A, a plurality of aggregates 20A, 20B, 20C are associated in a frame state to constitute a base 9, and the unit 8 and the conveyor 1B are fixed to an upper part of the base 9. According to this, even if a dirt of the conveyed article is dropped on the conveyor 1, the dirt is not stored on the base 9, but dropped on a floor through the frame to prevent the dirt from being adhered to the base 9. When cleaned, since no dirt is stored on the base 9, the cleaning can be facilitated. Since upper parts of the aggregates of the base do not have large areas, the cleaning is facilitated. A cleaning water or the like at the time of cleaning is not retained on the upper part of the base, and hence a work such as wiping or the like can be omitted. Since a beam material 21 is installed between the aggregates 20A for forming the upper part of the base 9, a strength of the base can be improved, and the degree of freedoms of a fixing position of the metering unit and the like can be increased.
