Conveyor with Tracking System Accurate Belt Tracking Is the Key for Smooth Operation Tension Terminal with Hydraulic bernmatic Belt Tensioning and Tracking System Tension Force 1500 kn THE CHALLENGE: MONITORED BELT TRACKING AND PERFECT BELT TRACKING CONTROL Steel belts are at the heart of every continuous production process, regardless of single or double belts application. Such processes usually involve large variations in pressure and fluctuating temperatures. This imposes heavy strains on the steel belts, and may result in premature wear and tear and expensive downtime. Berndorf Band Engineering offers two different systems. Which of these two systems is better suited to your application depends mainly on whether your belt machine is already equipped with belt tensioning equipment. Belt tensioning equipment NOT installed: bernmatic belt tensioning and tracking system Belt tensioning equipment installed: bernmatic tracking roller Following factors determine the lifetime of steel belts and their trouble-free operation: Belt tracking: belt shape, alignment of support rollers, temperature and contamination significantly effect belt tracking. Trouble-free operation can only be ensured by controlled, straight belt tracking. Belt tension: Alterations in belt length caused by changed process or ambient conditions may result in inadequate belt tensions. Transverse welds may become overstretched as a result, destroying the belt. The bernmatic belt tensioning and tracking system is THE solution to monitor and control belt tracking and belt tension. YOUR BENEFITS Reduced downtime of your conveyor coupled with increased productivity since continuous control ensures optimal belt running. Faster belt replacement due to automatic adjustment of belt tracking. The control parameters are adapted to the new belt geometry when the belt is run in. Options/executions: Customers demands and specifications vary considerably. Berndorf Band Engineering therefore offers various options and executions, such as remote maintenance, various bus systems for communication with the main line, and a variety of belt edge sensor systems. 2 3
Linear Drum Guides with Hydraulic Cylinder of the bernmatic Belt Tensioning and Tracking System bernmatic Belt Tensioning and Tracking System Visualization of the bernmatic Parameter PRINCIPLE OF OPERATION ADVANTAGES AND STRENGTHS The bernmatic belt tensioning and tracking system is a technologically advanced solution. Belt tracking is achieved by horizontal adjustment of the tensioning drum. At the same time the belt tension is kept constant by precise positioning of the drum. The bernmatic belt tensioning and tracking system will be used especially in systems where a very precise control of belt tension and tracking are required. Further to this existing machines may be retrofitted with the bernmatic belt tensioning and tracking system. THE CONTROL ALGORITHM OF THE bernmatic BELT TENSIONING AND TRACKING SYSTEM Berndorf Band Engineering s active belt tracking system monitors belt position continuously and controls both sudden and long-term disruptions reliably. At the same time the tension of the belt is monitored and kept constant. A combination of precise control of belt tension and belt tracking means that an additional drive unit is normally not required. Smooth control of the steel belt due to precise linear measurement of the belt position. Protection of the steel belt against damage: a multistage safety system in the control software prevents damage to the belt edges and cross welds. Use of world leading automation components (PLC) for control system. The bernmatic system can be linked to the superordinate control and visualization system of your plant for displaying recorded data and messages. Spare parts are available for a long period of time but can also be obtained from the manufacturers world-wide distribution network. Operation and tracking analysis by means of a graphical touch panel Control of belt tracking independently of speed Optional: Maintaining a minimum safe belt tension in the event of electrical power supply failure by means of a backup system with an independent source of energy, such as compressed air. 4 5
Belt Tracking Roller with Vertical Adjustment bernmatic Belt Tracking Roller Electrical Control Unit with Touch Screen Operation PRINCIPLE OF OPERATION ADVANTAGES AND STRENGTHS The bernmatic belt tracking roller is an adjustable support roller. Precise belt tracking is ensured by horizontal or vertical adjustment of the rollers. The system will be installed close to the tail drum. This system is suitable for use in conveyor installations already fitted with a belt tensioning system, where the main priority is belt tracking. THE CONTROL ALGORITHM OF THE bernmatic BELT TRACKING ROLLER: Berndorf Band Engineering s active belt tracking system monitors belt tracking continuously, reliably controlling both sudden and long-term disruptions. Easy integration of precise belt tracking into existing systems Compact design for easy installation and start-up Use of world leading automation components (PLC) for control system. This ensures that the bernmatic system can be linked to the superordinate control and visualization system of your plant. Recorded data and messages are not only displayed on the integrated monitor, but can also be integrated into your system. Spare parts are available for a long period of time, and can also be obtained from the manufacturer through their world-wide distribution network. Operation and tracking analysis by means of a graphical touch panel Control of belt tracking independently of speed Installation and commissioning can be carried out on site by your own staff 6 7
