Combination weighing apparatus with discharge chute including slide surface

A combination weighing apparatus comprising:

• a plurality of hoppers that receives articles inputted from an outside, temporarily stores the articles, and discharges the stored articles downstream;
• a discharge chute that receives the articles discharged from the hoppers and causes the articles to slide downstream;
• an acquisition unit that acquires weight values of the articles stored in each hopper;
• and
• a control unit that performs combination calculation on the basis of the weight values acquired by the acquisition unit and discharges the articles from a hopper determined by the combination calculation to the discharge chute, wherein
• the discharge chute includes:
• a first slide surface having a plurality of openings;
• and
• a plurality of second slide surfaces, each of the plurality of second slide surfaces covers a part of a corresponding one of the plurality of openings and is disposed at a position on an inner side of the discharge chute with respect to the first slide surface,
• each of the plurality of second slide surfaces is formed continuously with the first slide surface on an upstream side, a left side, and a right side of each of the plurality of openings, and
• each second slide surface of the plurality of second slide surfaces includes:
• a left flat surface rising from the first slide surface toward the inner side on a left side of the corresponding one of the plurality of openings;
• a right flat surface rising from the first slide surface toward the inner side on a right side of the corresponding one of the plurality of openings;
• and
• an upper flat surface that connects the left flat surface with the right flat surface.
