Avoid conveyor belt accidents, conveyor belts are not roller coasters

Conveyor belts are the “non-stop” heart of industry. They keep sending materials from one point of production to another, like an invisible assembly line. However, precisely because of their irreplaceability, conveyor belt accidents are also heard from time to time. Unlike the thrill of riding a roller coaster at the final destination, conveyor belt accidents are not so “exciting”, but they often bring equally heavy consequences. Imagine how dangerous it is when employees accidentally get caught in this endless conveyor flow. Therefore, reducing these accidents is not only crucial to the safety of employees, but also the cornerstone of ensuring smooth production.

 

In fact, companies need not only efficient operation of equipment, but also its ability to continue working without accidents. Just like a car, if it is properly maintained, it will bring you great efficiency, otherwise it may push you into a disaster.

1. Common types of conveyor belt accidents: “daily mistakes” that are not dangerous

To prevent conveyor belt accidents, you must first know where these accidents come from. They are not just a sudden stop of the equipment or too much material accumulation, but a complex systemic problem. Let’s take a closer look at these types of accidents and learn how to better deal with them.

 

1.1 Personnel Involvement Accidents

If an operator is not careful, his sleeves or hair are accidentally caught in a high-speed conveyor belt. This is like a common horror plot in a movie, but in reality, such accidents happen much more frequently than people imagine. Because the conveyor belt runs at an extremely high speed, the occurrence of an involvement accident is almost instantaneous, and the operator may have suffered serious injuries before realizing the danger. Data shows that involvement accidents account for a large proportion of conveyor belt accidents, and this type of conveyor belt accident can be completely avoided by simple safety measures, such as wearing tight work clothes and wearing protective equipment.

1.2 Accidents caused by equipment failure

Every conveyor belt will wear and age over time. If maintenance is not carried out in time, equipment failure will be inevitable. Conveyor belt accidents caused by equipment failure may occur in scenarios such as belt breakage, drive shaft jamming, and even motor overheating. This type of accident has a particularly serious impact on the production line. It may not only cause the entire production process to stagnate, but also cause high maintenance costs and potential employee injuries. Regular inspections of equipment and timely replacement of aging parts can greatly reduce the probability of such conveyor belt accidents.

 

1.3 Material accumulation and blockage

In the face of large conveyor belt equipment, the cause of failure is often coal slag, minerals, etc. that fall from the conveyor belt, which leads to the jamming of the conveyor belt and the conveyor belt roller, which is a common but easily overlooked accident. Imagine that the conveyor belt is constantly conveying a large amount of goods, but due to too much material or improper operation, it suddenly accumulates and is transferred to the equipment transmission device at the bottom. The conveyor belt cannot continue to operate normally, and it is very easy to cause material overflow or equipment jam. This situation will not only cause production stagnation, but may also cause more serious equipment damage and even secondary accidents. Therefore, companies need to ensure that the materials on the conveyor belt are evenly distributed and track the flow of materials in real time through the monitoring system to avoid the occurrence of conveyor belt accidents.

 

1.4 Static electricity and fire risks

In some specific environments, static electricity may become the “fuse” of fire. When the conveyor belt is running, especially in a dry environment or when handling flammable materials, static electricity can quickly accumulate and cause sparks, leading to fire. This kind of conveyor belt accident is often very dangerous and can threaten the safety of the entire working environment. Therefore, companies need to ensure that the conveyor belts are made of anti-static materials and take additional protective measures, such as regularly checking humidity levels to ensure that the production environment is not prone to static accumulation. Static electricity is only one aspect, and different industries may have different related problems, so it is important to choose the right conveyor belt material.

 

2. Safe operating specifications: make the conveyor belt “obedient”

To keep the conveyor belt system in good operation at all times, safe operating specifications are essential. Every action of the operator may affect the operation of the conveyor belt, so developing and following strict operating procedures is the fundamental way to reduce conveyor belt accidents.

 

2.1 Systematic operator training

Safety starts with training. The operator’s skills and knowledge are the first line of defense to avoid conveyor belt accidents. Every operator needs to receive systematic safety training to understand how to safely start, stop and operate the conveyor belt, as well as how to respond to emergencies such as equipment failure or material blockage. Training should also include potential risks in conveyor belt operation, such as warning signs of being involved in accidents and equipment overload. Through continuous training, operators can quickly identify and respond to unexpected problems, reducing the possibility of accidents. However, many company managers or operators participating in training often ignore this problem, always thinking that such things will not happen to the company or to themselves.

 

2.2 Use personal protective equipment (PPE)

Operators without protective equipment are like “bare-chested”, and the risk is doubled. Personal protective equipment (PPE) is the basic safety guarantee for operators working in conveyor belt systems. Operators should wear protective gloves, hard hats, goggles and other equipment to prevent clothing or body parts from contacting high-speed conveyor belts. Ensuring that employees regularly check and replace these equipment is also an important step to ensure safety. If personal protective equipment is properly used, many conveyor belt accidents can be completely avoided.

 

2.3 Install safety signs and alarm systems

Each dangerous area of the conveyor belt system should have clear safety signs, or operating instructions for related equipment, telling operators which places should not be approached, or reminding operators to pay close attention during work to increase warnings or prevent misoperation. For example, setting up “No Approach” or “Danger” signs in high-risk areas can effectively reduce the chance of operators accidentally entering dangerous areas. In addition, companies should install alarm systems at key locations on conveyor belts to promptly alert operators to potential safety issues. Once an abnormality occurs on the conveyor belt, the alarm system can immediately issue a warning to prevent the accident from expanding. 

3. Regular maintenance and equipment inspection: Give the conveyor belt a “SPA”

 

Even the best conveyor belts require regular inspection and maintenance. Equipment maintenance is not only the key to ensuring the normal operation of the conveyor belt system, but also an important means to reduce conveyor belt accidents.

 

3.1 Check the tension and wear of the conveyor belt

 

The tension and wear of the conveyor belt directly determine its operating efficiency. Excessive tension may cause the belt to break, while too little tension will cause the conveyor belt to slip, affecting the material transmission efficiency, and even causing the conveyor belt to jam. Therefore, companies should regularly check the tension of the conveyor belt to ensure that it is in the appropriate range, or add a tensioner through digital equipment for adjustment. In addition, wear is an inevitable problem in the long-term use of conveyor belts, especially those that are often in contact with sharp or heavy materials. Regularly checking the wear of the conveyor belt and replacing it when necessary is an effective way to reduce accidents.

 

3.2 Equipment lubrication and cleaning

The various components in the conveyor belt system need to be properly lubricated to reduce friction and wear. If there is a lack of lubrication, the equipment may heat up during operation, increasing the possibility of failure. The lubricating fluid not only plays a lubricating role, but also can cool the conveyor belt to a certain extent. The conveyor belt continues to generate heat by friction with the contact parts during long-term work, and regular cleaning work helps prevent dust, debris, etc. from accumulating on the conveyor belt and affecting its normal operation, just like the oil filter needs to be replaced every 5000-10000km for a car. Keeping the equipment lubricated and clean can not only extend the life of the equipment, but also reduce the chance of conveyor belt accidents.

 

3.3 Implementing the lockout/tagout procedure (LOTO)

When repairing equipment, the most feared thing is the sudden start of the conveyor belt. The lockout/tagout procedure (LOTO) is to avoid this danger. It locks the power supply and mechanical components of the conveyor belt during maintenance to ensure that the equipment will not start accidentally when the maintenance personnel operate it. This can be referred to in the maintenance manual of Airbus. When Airbus performs maintenance or maintenance, it will go to the cockpit to pull out the corresponding circuit breaker and insert the pin to prevent it from being inserted. This procedure not only ensures the safety of maintenance personnel, but also prevents the equipment from suffering further damage during maintenance.

4. Optimize workflow and technological improvement: give the conveyor belt system a new look

Imagine if your conveyor belt system no longer requires frequent manual intervention, can be adjusted in real time according to production needs, and can even detect and repair faults by itself. This is not a fantasy of the future, but a goal that can be achieved through optimizing workflows and technological improvements. By introducing advanced automation technology and intelligent systems, enterprises can significantly reduce the occurrence of conveyor belt accidents while improving production efficiency.

 

4.1 Introduction of automation technology

Automation technology is the soul of modern industry and a powerful weapon to reduce conveyor belt accidents. Traditional conveyor belt systems rely on manual operation and maintenance, while automation systems can monitor the status of conveyor belts in real time through sensors and intelligent control systems and make automatic adjustments. For example, sensors can detect the material load and running speed on the conveyor belt, and automatically stop the equipment when overload or abnormal conditions occur, avoiding accidents caused by equipment overload or failure.

 

Automation technology can not only reduce the risk of accidents, but also improve production efficiency. For example, in e-commerce warehouses, automated conveyor belt systems can automatically sort and convey materials according to order requirements, reducing the error and accident probability of manual operation. Such systems minimize the risk of conveyor belt accidents by reducing the direct involvement of operators.

 

4.2 Real-time monitoring and feedback system

Real-time monitoring system is another important technology to ensure the safe operation of conveyor belt systems. By installing sensors and cameras, enterprises can monitor the operating status of conveyor belts in real time. Once an abnormality is detected, the system will immediately issue an alarm and make feedback adjustments. For example, if the temperature of the conveyor belt is too high or there is too much material accumulation, the monitoring system can automatically reduce the speed of the conveyor belt or even suspend operation until the problem is resolved.

 

The benefit of this technology is that it reduces the interference of human factors and ensures that the conveyor belt system is always in a safe operating state. Especially in a long-term high-intensity production environment, the real-time monitoring system can prevent the equipment from overheating or overloading, and reduce the occurrence of conveyor belt accidents.

 

4.3 Install protective devices and emergency stop buttons

In order to increase the safety of the conveyor belt system, enterprises should install protective devices and emergency stop buttons at key locations, and in the use of some long-distance conveying systems, many cameras will be added to monitor the real-time situation of the conveyor belt to reduce the possible false alarms of the monitoring system or feedback system. These devices are equivalent to the “airbag” of the conveyor belt system, which can quickly interrupt the operation of the system in an emergency to avoid casualties and equipment damage.

 

The protective device can effectively isolate the operator from the high-speed conveyor belt to prevent accidental involvement in the accident. The emergency stop button is the operator’s last line of defense in an emergency. After pressing the button, the conveyor belt system will stop immediately to avoid a wider range of injuries. The combination of these two can significantly reduce the severity of conveyor belt accidents and protect the safety of employees and equipment.

5. Improve safety culture and reduce human errors: the soft power of conveyor belt safety

No matter how technology advances, the foundation of safety still lies in people. Establishing a good safety culture is a key step to reduce conveyor belt accidents. By improving employees’ safety awareness, companies can fundamentally reduce human operating errors and integrate safe operating standards into corporate culture.

 

5.1 Establish a safety responsibility system

Every employee must understand his or her safety responsibilities when operating a conveyor belt. Safety is not a person’s job, but the common responsibility of every team member. Companies need to establish a clear safety responsibility system to ensure that every employee is aware of his or her responsibilities, especially in conveyor belt operation and maintenance.

 

This responsibility system should run through all levels of the company, from management to front-line employees, and everyone should be responsible for the safe operation of the conveyor belt. Through clear division of responsibilities, employees will be more proactive in safety management and reduce conveyor belt accidents caused by neglecting safe operations.

 

5.2 Regular safety assessment and incentive mechanism

In order to further enhance employees’ safety awareness, companies can motivate employees to maintain high standards of safety operations through regular safety assessments and incentive mechanisms. Safety assessments can help companies identify potential risks and provide employees with specific suggestions for improvement. In this way, companies can not only prevent accidents, but also improve the overall safety culture.

 

Let the future of conveyor belts with both safety and efficiency become a reality

Conveyor belt accidents are not inevitable. Through reasonable safety operating specifications, advanced automation technology and strong safety culture construction, enterprises can completely minimize the risk of conveyor belt accidents. With the continuous advancement of technology, conveyor belt systems will become more intelligent and safe, which can not only improve production efficiency but also protect the lives of employees.

 

In the future production environment, conveyor belt systems will no longer be just tools for material transportation, but also intelligent, safe and efficient partners. They can not only be flexibly adjusted according to production needs, but also ensure that they are always in a safe operating state through real-time monitoring and feedback systems. For enterprises, improving the safety of conveyor belt systems can not only reduce the accident rate, but also improve overall production efficiency and achieve a win-win situation.
