Inspection method of checkweigher

Checkweighers are now very commonly used in production lines in various fields. As electronic industrial equipment, it is obvious that they cannot be used all the time after installation. It must be inspected daily and its performance shall be verified. So how to carry out daily inspection and performance verification on the checkweigher?

Daily inspection of checkweigher

After confirming that it has been energized and preheated for a period of time (for example, 15min), the conveyor of the checkweigher can be started to run without load, operate the corresponding keyboard, and issue instructions to adjust the zero point. Empty the carrier and observe whether the display value of the weighing indicator is zero, if it is not zero, it can be set to zero manually.

The product can then be tested. First put the product in the center of the carrier, read the displayed value, and then start the checkweigher conveyor to enter the dynamic test, let the product pass the carrier, and the weight value read when the product passes the carrier dynamically It will be different from the weight value in the static test. If it is within the allowable error range, it will meet the requirements. Let the product pass through the carrier several times (such as 10 times, 20 times), and carefully observe the repeatability of the checkweigher. If the reading error is large or the repeatability is not good, you should check whether there is a card in the mechanical part, whether there is a problem with the installation of the load-bearing device.

In general, performance verification recommendations should be conducted by authorized engineers once a year or every two years to verify that the equipment still maintains the specified accuracy. The main content of performance verification is to conduct the following two tests:

1. Accurate weighing

2. It can be correctly eliminated according to the weight deviation of the product.

In addition, it should be ensured that the following functions of the checkweigher system are normal and effective:

1. All additional warning/signal equipment

2. The safety system works.
