8.3 Cases of Checkweigher Conveyors - Final Thought
With the development of technology and efficiency, the market for automatic checkweigher has improved well. Various industries need it to ensure that the products meet weight requirements and higher inspection efficiency.
A comprehensive understanding of checkweighers can help you make the right choice.
▎1. What is the Checkweigher Conveyor
In the complete packaging process, the inspection process is indispensable because many accidents in the production process cannot be avoided, which will lead to the final products not meeting the requirements.
Aim to ensure that the products meet 100% of the production requirements. The inspection section is added to remove the unqualified products and keep the qualified products leading to 100% qualification rate.
In general, the checkered part is usually located at the end of the packaging line, using different special machines to test the data of all aspects of the product.
In the past, due to undeveloped technology, workers often needed to operate the equipment to complete the inspection process manually.
For example, for weight inspection, they would weigh the products on the conveyor belt on an electronic bench scale, then put the qualified products back on the conveyor and the unqualified ones in the designated area.
With the development of automation technology, the speed of manual inspection is difficult to meet the production requirements. So, automated inspection technology has replaced manual inspection.
People combine checkweighers with rejection systems to design automatic checkweigher conveyors. It has three major functions: check weighing, conveying, and rejecting, and it does not require manual participation and is completely controlled by a computer. Accurate and efficient.
With the checkweigher conveyor system, it can complete weight checking and rejecting during product travels.
The speed of the conveyor belt can be set as variable speed, which is energy-saving and environmentally friendly. The conveyor belt stops when there are no packages and starts to work when it detects packages.

▎2. Components of Checkweigher Conveyor
Compared to other auxiliary packaging machines, the components of checkweigher conveyors are not complicated and are made up of the following parts:
2.1 Belt Conveyor
The heavy belt conveyor is the power mechanism of the complete checkweigher conveyor system. It is responsible for driving the product in constant forward motion. Due to the large weight of most packages, the belt is large and uses high-power three-phase motor-driven rollers.
We have different types of conveyors for different products, such as belt conveyors, chain conveyors, and roller conveyors.
2.2 Weighing Sensors
The load cell is located underneath the conveyor. The deformation of the load cell is converted into a power signal and transmitted to the control computer, which then displays the weight on the screen.
The size of the weighing table determines the number of load cells. The larger the weighing table size, the greater the number of load cells. All the load cells come from international top brand products to ensure the accuracy of weighing and checking.
2.3 Electrical Controls
This part controls the operation of the equipment and is responsible for processing and judging the weighted data, as well as fulfilling the functions of storing data and various external connections and communications.
All components are installed in the cabinet. The cabinet also has USB and Ethernet ports for wired data transmission.
2.4 Touch Screen
The operator completes all interactions with the device through this touch-enabled screen. It can display the equipment’s operating status and the products’ weight data, as well as some basic data such as time.
By touching the screen, the employee can control the equipment weighing start/stop and belt operation, set preset parameters, etc.
2.5 Alarms System
The alarm system consists of an alarm light and alarm sound to alert the operator visually and audibly. When the product is normal, it lights up green; when there is a substandard product, it lights up red and makes a loud sound.
2.6 Rejecting System
The reject system comprises a cylinder-driven pusher plate and a roller conveyor.
When there are unqualified products, the checkweigher sends an electrical signal. The reject machine receives the electrical signal. When the products reach the front of the pusher plate, the cylinder drives the pusher plate to push the products away from the packaging line.
At the same time, if the customer also has an optional metal detecting machine, the rejecting machine can also receive the electrical signal from the metal detecting conveyor.
2.7 Machine Racks
The 304 stainless steel frame provides stable support to ensure the operation of the whole equipment.
The stainless steel is anti-corrosion and rust-proof, which can be used for a long time. And the rack legs can be designed as adjustable height structures to meet the requirements of different production environments.
▎3. How Checkweigher Conveyors Work
The overall workflow of the checkweigher machine can be divided into the following four steps.
Step 1: Weighing Preparation
Employees are required to set the preset weight and checkweigher conveyor speed to ensure the spacing between bags and the weighing accuracy.
Step 2: Weighing Process
The load cell deforms when the bags enter the weighing area and sends an electrical signal. The system receives the signal and processes it by selecting the signal from the stable area to derive the product weight.
Part 3: Sorting Process
When the control computer gets the bag weight signal, it compares it with the preset weight range. If it meets the requirements, the pushing cylinder does not work when the bag arrives on the reject conveyor; conversely, when the unqualified bag arrives, the cylinder works, and the pushing plate pushes it out of the bagging line issues an alarm.
Part 4: Report Feedback
The automatic checkweigher can record signals and record various data, including weight, number of qualified bags, number of unqualified bags, etc. It can also export Excel and customize various data to facilitate viewing the actual operation of the packaging line.
▎4. Application of Checkweigher Conveyor
Because checkweigher conveyors have a strong load-bearing capacity and belong to packaging inspecting equipment, they are used in various industrial sectors.
They are also widely used for weighing and testing functions of solid granular powder materials, such as concrete, cement, fertilizer, grain, salt, sand, and other industries. We also call it inline checkweigher because it can be integrated at the end of any packaging line.
In addition to bags, checkweigher conveyors can also be used to weigh different shapes of containers, such as boxes, bottles, and cans, all of which can meet the requirements of efficient inspection.
▎5. Types of Belts
To meet the conveying requirements of different industries, we offer a wide range of material options for conveyor belts so that you can make the right choice according to the characteristics of your product:
- PVC Belt
Most people choose PVC belts. Because PVC belt is cheaper than PU belt, and the surface can do anti-static treatment, dust or solid particle material will not get on the belt.
- PU Belt
PU is another common material. It is more durable than PVC because it is more abrasion resistant and is usually used to transfer large-weight bags.
- Mesh Belt
Using mesh belts can improve conveying efficiency when transporting materials that require large amounts of air.
- Modular Belt
Modular belts offer better flexibility and are your best choice when you need to make some changes in the horizontal direction.
Our technicians will provide you with the necessary help to make the most suitable choice for your material and packaging needs. Contact us now.
▎6. Benefits of Checkweigher Conveyor
