Method for measuring void ratio of cigarette capsule

Abstract

The invention discloses a method for measuring the void ratio of a cigarette capsule. The measuring method comprises the following steps: (1) detecting the external tangent volume of a to-be-measured cigarette capsule by a three-dimensional measuring device; (2) unpacking the to-be-measured cigarette capsule, finding an arrangement model of cigarettes in the to-be-measured cigarette capsule in a preset cigarette arrangement model base according to the arrangement condition of the cigarettes in the capsule, measuring the diameters and lengths of the cigarettes, and calculating the initial packaging volume of the cigarette capsule; and (3) substituting the external tangent volume and the initial packaging volume of the capsule in a formula shown in the specification to obtain the void ratio of the cigarette capsule through calculating, wherein the external tangent volume of the capsule is the minimum external tangent cuboid volume of the cigarette capsule, the initial packaging volume of the capsule is the minimum external connecting cube volume occupied by all the cigarettes which are arranged according to the arrangement model in the capsule, and k is a necessary space factor of the cigarette capsule.

Description

technical field [0001] The invention relates to the technical field of restricting excessive packaging of cigarettes, in particular to a method for measuring the void ratio of small cigarette boxes for restricting excessive packaging of cigarettes. Background technique [0002] In the general environment of restricting excessive packaging of commodities, the problem of excessive packaging of cigarettes cannot be ignored. In response to this problem, the tobacco industry has proposed specific measures including limiting the void ratio of packaging, limiting the cost ratio of trademark paper, and prohibiting special-shaped packaging, effectively curbing excessive packaging of cigarette products. [0003] Cigarette packaging void ratio is an important way to examine whether cigarette products are overpacked. In the tobacco industry, the void ratio of cigarette packaging refers to the ratio of the unnecessary space volume in the package (except for cigarettes and the original p...

AI Technical Summary

Problems solved by technology

The quantification method of void ratio does not examine the void ratio in the small box well. In order to create a high-end consumer experience, some cigarette manufacturers complicate and luxurious the space design in the small box, and there is a tendency to overpack

Limiting the porosity of small boxes is an effective way to limit excessive packaging of small boxes, but the method for measuring the porosity of small boxes has not yet been proposed
