Development of combination scales
Â
The world combination scale technology began in Japan.
In response to the Japanese Agricultural Association's request to solve the problem of green pepper weighing, Japan's Ishida Corporation developed the world's first multi-head weighing machine in 1973 . From this combination scales are on the stage of history.
The weighing range of the combination scale is only applied to the weighing of agricultural products, and gradually expanded to snack snacks, processed meat, candy, brittle food, frozen food, metal and rubber parts and even medicines; the structure and control system of the combination scale is also Simple mechanical weighing, only the weighing bucket is gradually developed to apply the load cell, and the weighing analog signal is converted into digital signal for combined calculation. The standard microcomputer combination scale is constantly improved, boldly innovative, and now serves the rapid development. modern industry.
Seeing the magical effect of combination scales, entrepreneurs from advanced countries such as Germany, Poland, Denmark, Czech Republic, Italy, and the United Kingdom have stepped into this potential area to share a piece of cake.
Of course, China is not far behind.
In the past, China did not have the corresponding technical level to independently develop and produce microcomputer-based combination scales, so it has always relied on imported products. Due to the relatively high import price, it has hindered the widespread application and popularization of microcomputer combination scales. With the rapid development of modern industry, traditional manual weighing technology is difficult to meet the requirements of weighing, packaging industry in weighing accuracy, speed, weighing range and so on. In order to break the obstacles of weighing technology to domestic processing enterprises, after years of research and experiment, Guangdong Haichuan Intelligent Machine Co., Ltd. developed and produced the first microcomputer combination scale with independent intellectual property rights in China in 2005 . It has created a new era of domestic microcomputer combined scales in the field of quantitative weighing packaging, and has since broken the monopoly of developed countries on combined scales.
However, due to the slow start of most domestic microcomputer-based combination scales, except for the extremely small number of leading enterprises, it is difficult for other enterprises to break through. Therefore, there are only a handful of combined scale enterprises. However, with the rapid development of packaging enterprises at home and abroad, the demand for symmetrical quantity equipment continues to expand, and the scale of expansion of domestic combination scale enterprises is also accelerating.
With the continuous development of packaging enterprises, taking into account the comprehensive situation of cost and weighing speed, more domestic high-speed, high-efficiency development-oriented enterprises have purchased economical and practical domestic combination scales, and gradually eliminated the previous manual quantitative weighing packaging. Backward way. The domestic packaging industry has taken a new step in improving the production environment, improving the automation of production and management, and reducing costs and sanitary packaging. This is an opportunity and a challenge.
In the face of increasingly fierce domestic and international markets, how can domestic enterprises embark on the path of sustainable development?
Among them, Haichuan Company explained the following as its actions:
Innovation ---- Only continuous change, innovation is the road to development.
From traditional standard combination scales to salad scales, potato scales, chopsticks scales, noodle scales and waterproof scales specially designed for different materials; developed into miniature combination scales designed to reduce the size of equipment; developed to increase weighing Speed ​​double-slot combination weigher, three-layer memory bucket combination scale; even developed into an integrated machine that combines the combination scale and packaging machine ...
It is believed that the combination scale is still developing in the direction of small size, high speed, high precision, integration, and little influence on the environment, who will run faster and who will run farther.
