The automatic checkweigher
is usually used for product quality inspection on the production line. Many issues need to be considered during installation and use, because these factors may directly affect the results of the automatic checkweigher. The following are three factors to consider when installing an automatic checkweigher.
Consider the operating environment of the checkweigher
Before purchasing a checkweighing system, you should first carefully consider the checkweighing operating environment and the characteristics of the product. A series of factors such as humidity, temperature changes, dryness, excessive vibration, air dust, etc. will affect the accuracy of weighing. If the operating conditions are poor and the humidity and dust content in the air are too high, moisture and dust will enter and damage the conveyor belt and the mechanical devices of the load cell, thereby shortening the service life of the machine.
In order to eliminate the impact of the humid and high dust operating environment, some checkweighing techniques with special functions should be selected, such as with a sealed enclosure, processed from a single piece of plastic or metal, etc. In this way, dust and moisture can be prevented from entering, and the internal precision weighing sensor, transmission system, and drive motor can be protected from damage, and premature aging can be avoided. At the same time, it should also be pointed out that you must not allow unnecessary movement or vibration around the weight sorting machine, such as vibration caused by an employee's rapid passing. Because even a small vibration or airflow will be detected by the sensitive checkweighing equipment, resulting in deviations in the measurement.
Install an automatic checkweigher suitable for the production line
The specific conditions of the inspected product determine the specifications of the automatic checkweigher. Before making a purchase decision, it is necessary to carefully evaluate the various characteristics and specifications of the automatic checkweigher to ensure that its model is indeed suitable for the needs of the production line. Before making such an investment decision, factors such as the weight and characteristics of the product being inspected, the type of packaging, and the location of the automatic checkweigher on the production line should be considered. The tested products also determine whether the conveyor system needs additional functions to ensure that the packaging direction is correct, the interval is correct, and the storage is stable before reaching the automatic checkweigher. The form of the packaging, the shape of the product, and the stability of the packaging, all of these factors will affect the accuracy of the weighing.
The installation of timing belts, screws, or wheel-like devices helps to ensure that the spacing of each package is correct, so that only one package passes the load cell at a time, and lateral clamping belts and transfer equipment can also be installed to ensure the stability of the package. In this way, the weighing accuracy can be optimized and the package can be correctly removed when the unqualified product is inspected. For example, a bottle of soft drink may shake slightly on the conveyor belt due to its high center of gravity, which will affect the measurement accuracy of the checkweigher. However, if the lateral clamping belt is installed close to the load cell, this kind of shaking can be eliminated and the bottle can be kept stable when weighing.
Install the checkweigher correctly
Choosing the ideal checkweigher according to your needs is a good start, and ensuring the correct installation of the checkweigher scale is also very important. Correct calibration of the automatic checkweigher to eliminate packages that are significantly higher or lower than the standard weight of the product will not only ensure that the product meets the requirements of legal metrology regulations but also reduce product waste. According to experience, the target weight should be slightly higher than the weight indicated on the packaging label, because this can ensure that the average weight of the product batch can meet the legal requirements. The precise automatic checkweigher can also set more stringent product target weight tolerances, thereby further reducing waste and largely eliminating the possibility of underweight products entering the subsequent links.
When installing the automatic checkweigher, you also need to follow the specific installation steps, and the checkweigher machine must be accurately debugged.
