Online checkweighing has gradually become an indispensable link in modern industrial production, especially in the production process of food and pharmaceutical industries. Measurement sorting machine in the product conveying process on the completion of the measurement of product metering, and will measure the measurement of metering and pre-set range comparison, by the control box to send out instructions to the measurement of unqualified products rejected, or different measurement range of the product to the designated area.

Measuring and testing machine usually consists of conveying mechanism, sorting mechanism, weighing mechanism. Among them, the weighing mechanism completes the collection of measurement signals, and sends the measurement signals to the control box for processing. The conveyor is mainly used to increase the speed to ensure that there is enough distance between the products. The sorting organization is used to reject the unqualified products after inspection.

The working process of checkweigher is as follows:

Weighing process

1, weighing module: weighing tray is the core module of the metering and sorting machine, the structural design and installation accuracy directly affects the detection accuracy of the system.

2, speed matching module: the measured object will be transmitted to the weighing mechanism, so that the distance between the two connected products to ensure that the weighing pallet will not be two products at the same time, to achieve stable and accurate weighing of product measurement, to ensure the accuracy of measurement.

3、Measurement sorting module: Measurement sorting module is the actuator of measurement sorting machine, which is composed of conveying part, pneumatic valve, hopper and so on. It accomplishes rejecting and sorting the unqualified parts of the objects. The rejecting method can be set as blowing, pushing, dialing, dropping and so on.

Report Feedback

Measuring and sorting machines have a measurement signal feedback function, usually the average measurement of the set number of products will be fed back to the controller of the packaging/filling/canning machine, and the control box will dynamically adjust the dosing volume to make the average measurement of the products closer to the target value.

In addition to the feedback function, the checkweigher can also provide a wealth of reporting functions, the number of packages per zone, the total number of packages per zone, the number of qualified, the total number of qualified, the average value, the standard deviation, and the total number of packages and the total total accumulation.

Measuring and sorting machine uses:

1、Detection of missing pieces of whole box products

The whole box packaging contains small packages of products, such as beverage boxes, large bags containing multiple small bags of products in the occasion, due to equipment or personnel factors, will result in missing products. The use of metering sorting machine on the large package for metering inspection, you can ensure that the large package will not appear in the phenomenon of missing products. For example, each case of 24 bottles of beverages, the normal measurement of each case is certain, check the measurement of each case can be found in the absence of the phenomenon of leakage.

2、Disaggregate and classify

Uneven measurement of the product is automatically categorized. Such as dividing chicken manufacturers to divide the size of chicken legs into a number of measurement range, you can use the measurement of the sorting machine for each chicken wing automatic weighing, and according to the set range of different measurements of chicken wings sorted into the appropriate device, so as to achieve the results of automatic sorting.

3、Inspection of product measurement

In the production of products, the measurement of products is re-inspected and unqualified products are eliminated to ensure that the measurement of products leaving the factory meets the requirements. This is conducive to ensuring the interests of consumers and manufacturers of both sides. Consumers will not suffer because of the lack of pounds and losses, manufacturers will not be because of customer complaints or even complaints and reputation damage.

4, feedback control

Measuring and sorting machine in addition to providing product measurement signals, unqualified products for rejection can also be in accordance with the average measurement and nominal measurement of the difference between the output feedback signal to the packaging and filling equipment, automatically adjust the average measurement to make it consistent with the set measurement, thereby reducing production costs. For example, crab metering sorting machine sorting crabs, crab sorting machine is mainly used in crab metering sorting, sea cucumbers, abalone, oysters, oysters and other seafood industry, will be the crab according to the measurement or size sorted into different levels, and then transported to the designated level device, automatically all the size of the crab according to the customer's metering requirements sorted into different levels.
