Problems solved by technology

However, when the conventional dynamic checkweigher weighs, the product needs to monopolize the weighing platform: that is, when performing dynamic weighing of a certain product, when the product enters the weighing platform, the previous product must be completely out of the weighing platform. The next product can only be weighed after the product is completely out of the weighing platform
In this way, the weighing of a single product will take a long time, so that the productivity is limited

Embodiment Construction

[0015] The technical solution of this patent will be further described in detail below in conjunction with specific embodiments.

[0016] see figure 1 , a high-speed dynamic weighing system for an automatic checkweigher, comprising a dynamic weighing unit 1, a photoelectric sensor 2, a weighing sensor, a microprocessor circuit and a man-machine interface. The human-machine interface adopts a touch screen. Microprocessor circuit adopts single chip microcomputer.

[0017] The working process of the high-speed dynamic weighing system of the automatic checkweigher, the specific steps are as follows:

[0018] Step 1, put the product in, wait for the photoelectric sensor 2 to detect that the product enters the dynamic weighing unit 1, start the dynamic weighing calculation, and perform a sliding window sampling of length N for the data of the weighing unit;

[0019] Step 2: Carry out weighted average of the data in the sliding window, calculate the variance, record the average va...

Abstract

The invention discloses a high-speed dynamic weighing system of an automatic weight checker. The system comprises a dynamic weighing unit, a photoelectric sensor, a weighing sensor, a microprocessor circuit and a man-machine interface. The invention further discloses a work flow of the high-speed dynamic weighing system of the automatic weight checker. The high-speed dynamic weighing system of the automatic weight checker settles a problem of scale platform occupation by a single product in weighing by an existing automatic weight checker, and determines whether to start weighing of a next product through intelligent determining to a product state in the weighing process. Through the algorithm of the high-speed dynamic weighing system, the automatic weight checker allows overlapping of the product on the scale platform, thereby reducing weighing time of the single product, improving productivity, reducing labor cost of enterprise employees, and realizing wide application prospect.

Description

technical field [0001] The invention relates to a dynamic weighing system, in particular to a high-speed dynamic weighing system of an automatic check weighing scale. Background technique [0002] A scale is a weighing instrument used to determine the mass of an object. Common scales include steelyard scales, platform scales, spring scales, electronic scales and pallet balances. With the development of science and technology and the formation of industrial scale, people have developed a dynamic checkweigher. Dynamic checkweigher is also known as sorting scale, sorting machine or automatic checking weighing device. It is suitable for products in the terminal process inspection of packaging assembly line. It provides a more economical solution for simple online checking weighing requirements. It has fast detection speed, It has the characteristics of high measurement accuracy and strong expansion performance. However, when the conventional dynamic checkweigher weighs, the pr...
