With the development of industrial automation and the increasing national supervision of the food and pharmaceutical industries, the application scope of online checkweighers is becoming wider and wider.
The medicines, cosmetics, daily necessities, etc. we use in our daily life are closely related to checkweighers. So how does a checkweigher work? Next, Shanghai Shiqian Industrial Co., Ltd., which is in the weighing field, will tell you.
The online checkweigher realizes high-speed and high-precision weight detection of products moving on the production line, and compares the detected weight with the preset upper and lower limit ranges to automatically sort out products that are too light or too heavy.
The online checkweigher is mainly composed of a material handling part, a weighing part and a rejecting part.
For the products to be inspected that are queued up on the assembly line, the running speed is increased through the sorting belt to ensure that there is sufficient distance between the products to avoid having two products on the weighing platform at the same time. After the product enters the checkweigher weighing platform, the system identifies the product to be inspected and enters the weighing area based on external signals (photoelectric, threshold).
The weighing part completes the collection of weight signals and sends the weight signals to the controller for processing to obtain the dynamic weight value of each product.
The rejection part is used to transport the inspected products away from the weighing area and reject products with unqualified weight. Depending on the shape and weight of the product, the methods of removal include air blowing, pushing rods, turning plates, etc.
The wide application of checkweighers has greatly improved product quality and optimized production processes for all walks of life, thereby helping them control costs, eliminate waste, and increase profits. Shanghai Shiqian Industrial Co., Ltd. has been committed to the development and application of checkweighers. For more product information, please contact us at any time.
