The predetermined weight-doubling relation is determined by the following specific steps:

when a fresh commodity is stored in the storage compartment 11 in advance, the weight of a bulk commodity in the fresh commodity is used as a first comparison weight, the weight of a commodity to be delivered is used as a second comparison weight, the preset doubling relationship is that the integral multiple of the second comparison weight is equal to the first comparison weight, the integral multiple of the first comparison weight is equal to the second comparison weight, and the integral multiple is 1-3 times.

Assuming that the first comparison weight is a and the second comparison weight is B, at this time, the weight conflict determination unit 29 calculates a, B, 2A, B, 3A, B, 2B, a, and 3B, respectively, and if these equations do not match, the weight conflict determination unit 29 determines that there is no predetermined duplication relationship between the first comparison weight a and the second comparison weight B, and further determines that there is no conflict between the weight of the bulk goods and the weight of the goods to be delivered.

When two fresh commodities are stored in the storage compartment 11 in advance, one bulk commodity is taken from the two fresh commodities, the weight of the two bulk commodities is used as a first comparison weight, the weight of the commodity to be delivered is used as a second comparison weight, the preset doubling relationship is that the integral multiple of the second comparison weight is equal to the first comparison weight, the integral multiple of the first comparison weight is equal to the second comparison weight, and the integral multiple is 1-3 times.

Assuming that the first comparison weight is B, C and the second comparison weight is a, in this case, the weight conflict determination unit 29 needs to calculate a + B-C, A + 2B-C, 2A + B-C, …, and 3A + 3C-B (i.e., the multiple between A, B, C and the remaining weight is doubled) in addition to a-B, 2A-C, …, 3B-a, and 3B-C, respectively (i.e., whether the weight between A, B, C and B is doubled), and if these equations are not met, the weight conflict determination unit 29 determines that there is no predetermined weight relation between the first comparison weight B, C and the second comparison weight a, and further determines that there is no conflict between the weight of the bulk commodity and the weight of the commodity to be delivered.

For convenience of description, in the above formulas, no parameter corresponding to the predetermined weight error is written, and in actual calculation, the weight collision determination unit 29 considers the predetermined weight error, and actually calculates a ═ B ± w, 2A ═ B ± w, and the like, where ± w is the predetermined weight error. In the present embodiment, the integral multiple is a multiple of 3 times or less, i.e., 1 time, 2 times, and 3 times; the predetermined weight error is allowed to be influenced during actual measurement and is generally within +/-3-10 g, and the predetermined weight error of the embodiment is +/-3 g.
