Method and device for electronically grading eggs through three-dimensional lifting

Abstract

The invention discloses a method for electronically grading eggs through three-dimensional lifting. The method comprises the following steps: A. synchronous material loading; B. electronic weighing; C. three-dimensional lifting; and D. egg unloading and discharging. The invention also discloses a device for electronically grading eggs through three-dimensional lifting. The device mainly comprisesfour parts: synchronous material loading, electronic weighing, three-dimensional lifting and egg unloading and discharging. The method and the device have the following advantages: as the three-dimensional lifting scheme is adopted, all grades of eggs are unloaded in different spatial heights, the space is fully utilized and the problem that all grades of eggs can not be unloaded from the transport lines because of mutual interference of egg paths which are more than 2 paths during plane electronic weighing and grading and are more than 3 paths during plane mechanical weighing and grading is avoided, so dozens of egg paths can be arranged side by side, the grading efficiency is greatly improved and 0.1 million of eggs can be graded through 30 egg paths per hour; and static electronic weighing is adopted and the eggs are static on fixed egg trays during weighing, so weighing is accurate, the accuracy can reach + / -0.2g and breakage caused by weighing is slight.

Description

technical field [0001] The invention belongs to the technical field of food processing equipment, and in particular relates to a poultry egg three-dimensional lifting electronic grading method and a grading device. It can realize high-efficiency automatic weighing and grading of poultry eggs. Background technique [0002] Weighing and grading by weight of poultry eggs (eggs, duck eggs) and egg products (salted eggs, preserved eggs) are important links in egg product processing. Important technical and economic indicators, the prior art egg sorting machine (patent number: 200420083435.9) and multifunctional egg sorting machine (patent number: 200420103632.2) adopt the plane layout classification method and the principle of mechanical weighing, the production capacity of the equipment is limited, generally The maximum production capacity of the three-row feeding and grading equipment is only 5,400 pieces per hour (divided into four grades). When the number of rows increases, ...

[0002] Weighing and grading by weight of poultry eggs (eggs, duck eggs) and egg products (salted eggs, preserved eggs) are important links in egg product processing. Important technical and economic indicators, the prior art egg sorting machine (patent number: 200420083435.9) and multifunctional egg sorting machine (patent number: 200420103632.2) adopt the plane layout classification method and the principle of mechanical weighing, the production capacity of the equipment is limited, generally The maximum production capacity of the three-row feeding and grading equipment is only 5400 pieces / hour (divided into four grades). When the number of rows increases, it is affected by the inertia of the machine movement, the vibration of the machine increases, and the damage increases significantly.

At present, some enterprises are developing electronic weighing and grading equipment, but they still adopt the plane layout and grading method. Since the feeding, weighing and grading devices of the equipment are arranged in the horizontal direction, it is difficult to greatly increase the output due to space constraints. At present, the maximum output Only 10,000 pieces / hour
