Conveyor belt manufacturers bear a great responsibility!
As the name suggests, conveyor belts transport goods, components, products and raw materials through the individual production processes. In order to avoid or minimize downtimes, it is therefore essential that the transport functions smoothly from the beginning to the end of production. This guarantees better quality and more orders!
Which applications are available?
In conveyor technology, the various belt conveyors are differentiated according to their possible applications. Conveyor systems are almost always stationary. The belts transport goods on roller conveyors over short or long distances around the clock. These are used especially in industry and mining. Conveyor belts, especially small conveyor belts, are regarded as environmentally friendly, productive and economical solutions in everyday operation. In the food industry it is impossible to imagine the food industry without the robust roller conveyors. But the conveyor belts are also in constant use at supermarket checkouts. But also post offices, railways and airports use conveyor belts for luggage and parcels. This makes it all the more important that producers pay attention to robustness, durability and economy during production.
One of the latest applications are so-called "moving walks". These are roller conveyors permanently mounted on the floor on which people are transported with or without luggage. Here, manufacturers must ensure that falling persons or their luggage cannot be trapped anywhere. Emergency stop buttons must be easily visible and accessible, just as on escalators based on the same principle.
Conveyor belts are also used in sports. Treadmills are based on the same principle. Manufacturers must be able to guarantee occupational safety
In the case of belt conveyors, there is a risk that hands or arms can be pulled in and out of the belt due to the constant rapid movement between the rollers and the belt. The person cannot react so quickly. Colleagues then usually reach the emergency stop rip cord or button too late. The drive power of conveyor belts in a quarry, for example, is 100 kW. This is much too fast to be able to stop the belt with your hand. In these cases, other safety rules come into play to ensure the necessary safety.
Manufacturers must guarantee that an easily accessible emergency stop facility - in this case a rip cord - must be available. In addition, manufacturers must ensure that all feed points on deflection and drive rollers are covered. The same applies to idlers which the belt cannot avoid (5 cm). Bottom belt rollers (up to a height of 2.5 m) must have a protection against tampering. In addition, appropriate safeguards must be provided at the entry points of tensioning devices on pressure rollers belt guide rollers , lower belt turning stations or in the lower belt.
Especially for belt conveyors, the safety regulations and EMC requirements can be found in EN 620:2002 and in the Type C standard according to EN 1070:1998.
What else should manufacturers of conveyor belt systems attach importance to?
In addition to safety, individual solutions, such as the angle of inclination of slanted conveyors or special ambient conditions (humidity) are also of interest to buyers. Belt conveyors are subject to the highest continuous stress. Therefore it is even more important to have a good customer service, maintenance and repair service. Spare parts should be readily available and appointments should be possible without delay. Small conveyor belts are used more often by SMEs. In this case, it is particularly important to have quick and competent solutions on hand or to have specialist personnel available. The quality of a manufacturer rises and falls with the quality of the customer service.
