Checkweigher Application

Automatic checkweigher is also known as: automatic checkweigher, weight sorting scale, weight sorting machine. It is a medium-low-speed, high-precision online automatic checkweighing equipment, which can be integrated with various packaging production lines and conveying systems. Mainly used for online detection of product weight, whether there are missing parts in packaging or product weight files.

Online checkweighing has gradually become an indispensable link in modern industrial production, especially in the production process of food and pharmaceutical industries. The automatic checkweigher completes the measurement of the product weight during the product conveying process, and compares the measured weight with the preset range, and the control box issues an instruction to reject the product with unqualified weight, or reject the range of products with different weights. Products are shipped to designated areas.

The automatic checkweigher is usually composed of a conveying mechanism, a sorting mechanism and a weighing mechanism. The weighing mechanism completes the collection of the weight signal, and sends the weight signal to the control box for processing. The main purpose of the conveying mechanism is to increase the speed and ensure that there is enough space between the products. The sorting mechanism is used to reject products that fail the inspection.

The working process of the checkweigher is as follows:

Weighing process

1. Front-end conveying mechanism: transfer the object to be measured to the weighing mechanism, on the one hand, give the object an initial speed, so that it can reach stability faster after entering the weighing mechanism; on the other hand, it can isolate and reduce the impact function of the front-end material to ensure measurement accuracy;

2. Intermediate weighing mechanism: This part is the key part of the entire mechanical system, and its structural design and installation accuracy directly affect the measurement accuracy of the system. It consists of conveying motor, photoelectric monitoring part and load cell. Complete dynamic weighing of objects;

3. Back-end sorting mechanism: This part is the action part of sorting, which is composed of conveying part, pneumatic valve, hopper, etc., and completes the rejection and sorting of unqualified parts. The rejection method can be set to blow, push, move, drop, etc.

report feedback

The checkweigher has a weight signal feedback function. Usually the average weight of a group of products is fed back to the controller of the packing/filling/canning machine. The control box dynamically adjusts the feed amount to bring the average weight of the product closer to the target value.

In addition to the feedback function, the checkweigher can also provide rich report functions, such as the number of packages in each area, the total amount in each area, the qualified number, the qualified total, the average, the standard deviation, and the total and total. Checkweighers can be used in various industries, such as food, medicine, chemical, beverage, plastic, rubber and other industries.
