Small ring egg grading and sorting system

technical field

The invention relates to a poultry egg grading and sorting system.

Background technique

As an important agricultural product, poultry eggs are not only rich in protein, lecithin and other nutrients, but also rich in sources, easy to eat, and taste in line with the eating habits of most people. With the rapid development of economy and society, people's requirements for the quality of poultry eggs are also increasing, and the deep processing and eating methods are also constantly improving. While the market demand for poultry eggs promotes the rapid development of the poultry and egg industry, it also brings huge challenges to the industry and accelerates the application of modern technology in poultry egg processing. Automated processing and handling equipment reduces labor intensity and helps to improve production efficiency and ensure product quality. Therefore, in the pretreatment of poultry eggs, the use of highly intelligent integrated equipment for processing is the trend of future development.

The total output of poultry eggs in my country accounts for about 1/5 of the world's total output. According to the report of the National Bureau of Statistics, the total output of poultry eggs in 2010 was about 29.42 million tons, accounting for 19% of the global total output in that year. However, production mainly depends on individual farmers and small-scale breeding enterprises. This small-scale and widely-distributed distribution mode makes the production and processing of poultry eggs in my country mainly rely on manual work, and the detection and grading mainly rely on visual inspection and experience. Specific ethnic eating habits determine that the main mode of consumption of poultry eggs in my country is fresh eggs, while consumption of poultry eggs after deep processing only accounts for less than 1% of the total output. The large demand for fresh eggs requires that poultry eggs can be safely and quickly from egg production to the end of sales. Due to uncertain factors such as the market, poultry eggs need to be stored for a certain period of time to be sold, so compressing the pretreatment time of poultry eggs as much as possible has become a common goal pursued by producers and sellers. Especially in seasons with high temperature, the shelf life of poultry eggs will be greatly reduced, which requires that the operations of cleaning, sorting and packaging of poultry eggs should save time as much as possible to ensure the quality of the products when they finally reach consumers. The limited efficiency of manual egg sorting and the increase in labor costs in recent years have become a huge barrier for many poultry and egg companies in my country to expand their markets and go abroad. Therefore, accelerating the use of automatic processing equipment and adopting a suitable automatic control system to complete cleaning, grading and packaging are the main development directions to solve this problem.

公司作为世界首家禽蛋自动分拣设备的研发者，起步于上个世纪五十年代，有着丰富的技术基础和行业经验，目前在该市场占有率已经达到60%，我国多数企业引进的设备均是出自该公司。 In addition, in the international poultry and egg trade, product testing standards are relatively high, and many rigid testing indicators cannot be achieved through manual testing or purely relying on experience, which has also become a bottleneck for Chinese poultry and egg companies to enter the international market. According to the report of the National Agricultural Information Network, the total output of poultry eggs in my country was 25 million tons in 2011, but the export volume was only 100,000 tons. Due to factors such as good computer technology foundation and developed industry, foreign countries already have a relatively mature set of automatic processing equipment, which has been put into use in large-scale breeding enterprises and achieved good results. Foreign core technologies impose a strict technical blockade on my country, which makes the use of imported equipment costly and restricts secondary development in my country. At the same time, factors such as the small scale of breeding in my country, scattered distribution, and low labor costs make many enterprises fail to adopt imported equipment due to comprehensive considerations such as economic benefits and applicability. At present, there are nearly 2,000 processing enterprises in the country, but most of them have an annual output value of less than 10 million yuan, and less than 15 have an annual output value of more than 100 million yuan. At present, the world's main automatic sorting and packaging equipment are produced in the Netherlands, Japan and the United States. The main general steps include collection of poultry eggs, cleaning and disinfection, grading, picking and packaging, and barcoding for fresh-keeping storage. Dutch

As the world's first developer of poultry egg automatic sorting equipment, the company started in the 1950s, has a rich technical foundation and industry experience, and currently has a market share of 60%. The equipment introduced by most companies in my country are from the company.

The large-scale automatic egg sorting equipment enables the eggs to enter the production line from the most primitive state, and finally complete the steps of cleaning, testing, grading and packaging based on different standards or comprehensive indicators such as quality, volume, and freshness. In addition, due to the irregular structure and fragility of poultry eggs, highly intelligent automatic processing equipment is required for processing. At present, domestic related research has made great progress, especially in the process of quality inspection and packaging, but there is no complete set of equipment with independent intellectual property rights. As one of the main components of automatic sorting equipment, the sorting manipulator plays an important role in connecting detection, pretreatment and packaging, and has become the key research object of many scientific research units. Although there are already many mature industrial manipulators suitable for various occasions on the market, such as Mitsubishi, Kawasaki, FANUC and other industrial manipulators with certain flexibility and openness control systems, the poultry and egg sorting manipulator should have The characteristics of rapid action, small movement impact, and specific adsorption mechanism at the end make it difficult for existing manipulators to be directly used in poultry egg sorting systems. In addition, due to the limitation of the value of poultry eggs, it is difficult for large-scale industrial manipulators to adapt to market requirements.

To sum up, the development of a more efficient and economical automated egg sorting manipulator is not only of great significance for the design of a complete automated egg sorting equipment, but also contributes to the rapid development of the entire automated sorting equipment.
