What is the significance of multi-head microcomputer
????The multi-head microcomputer combination weighing device is also called selective combination weighing instrument. It is composed of multiple weighing units with independent feeding and discharging structure. Generally, the microcomputer combination scale is composed of 8 to 32 weighing units. The computer uses the principle of permutation and combination to automatically and optimally calculate the weight values ??of each weighing unit to obtain a good combination that is close to the preset target weight value for packaging.
????The multi-head computer combination is said to have originated in Japan. Because the multi-head scale has good performance in terms of accuracy and speed, it has been rapidly and widely used in the food industry. The multi-head scale can weigh three types of materials: block, granular, and strip. The weighing of the block material can reflect the superiority of the multi-head scale. It solves the measurement error caused by the large weight of the block material. The bigger problem. The multi-head computer combination claims that the performance in both packaging accuracy and speed is greatly improved compared to the traditional measurement method. At present, the industry generally sets the weighing error of multi-head scales as a positive deviation of 0.5-1.0g (weighing range 500g). At the same time, because the multi-head scale uses a computer for calculation, the combination speed (ie, weighing speed) is effectively increased. A ten-head multi-head scale with a weighing speed of up to 70 times / min. Fourteen-head multi-head scale with a weighing speed Up to 120 times / minute. A confectionery factory in Fujian is a large-scale enterprise specializing in the production of various types of confectionery. Before 2004, it used the traditional measurement method (manual measurement). Its speed can only reach 25 times per minute. Each bag of candy (40g) is packed with at least 4g more candy due to inaccurate weighing.
????For example, a computer combination weigher with ten weighing units, each weighing unit weighs during weighing, and reads the weight data in each weighing hopper into the computer, and the computer performs the optimal combination according to the combined number The 10 weighing units can realize 1023 combinations in total, and the computer selects the combination that is close to the target weight value from these 1023 combinations. In this way, it is easy to solve the work of manual matching and it is difficult to achieve quantitative values, which meets the actual needs of modern packaging industry to adopt quantitative packaging.
????Multi-head microcomputer combination weigher adopts 10-head microcomputer scale and measuring cup weighing machine for quantitative weighing. What is the advantage of microcomputer combination scale? The packaging experts made a detailed comparison of this: the reason why the 10-head combination scale can achieve full integration of high precision and high speed, and effectively save labor and raw material costs, mainly because the computer 10-head combination scale can reach 1024 combinations. Carry out automatic combination measurement, so as to select a combination close to the target value for each weighing. For example, an ordinary confectionery factory, the product packaging specification is 100 grams per bag, based on 8 hours a day and 300 days a year, the annual output is about 850 tons.
????Compared with general weighing machines such as measuring cups, the computerized 10-head combination scale is used for quantitative weighing. The combination scale can save the labor cost of 6-10 operators for the manufacturer every year. 0.1 ～ 0.6g), it can save as much as 26 tons of raw materials for manufacturers in one year. In the field of food weighing, the combination scale has become synonymous with 'saving materials and labor'. In today's fierce market competition, increasingly standardized production management, and rapid increase in labor costs, the use of high-tech equipment not only brings directly measurable benefits, but also brings production management and concepts to the entire plant Great changes and impacts on the world.
