Description

Belt conveyor systems are always prone to belt misalignments for a variety of reasons. Reasons which can be broken down into those which can be influenced (e.g. installation errors) or those which cannot be influenced (e.g. the occurrence of tem- porary variable disturbances). This is where the intelligent de- sign of the BSG can provide possibilities of counter-acting belt misalignment. In comparison to other control systems, the BSG is a self-sufficient, electro-mechanical system which captures the belt position and moves the actuator into regulating the directional stability of the belt. The system allows the most minute and most exact belt position manipulation in the shortest of reaction times. The energy required for the whole sensoring and actuating elements is generated by the BSG itself and thus reduces the time and effort required for set-up and making the unit available. Thanks to the intelligent design, the unit can be installed at any point in the belt structure and can be used on both the carrying side as well as the return side of the belt. The BSG can be integrated into existing plant communi- cations where a variety of interfaces are available thus providing a considerable module for plant management.


Function

The belt position is detected via the touch-rolls of the rotary switch. The resulting analogue value is made available to the control electronics of the engine-gear control unit as a control variable. Should the belt leave its parameterized designated position, the integrated servo-drive drives a downstream worm gear and adjusts the steering idler. The touch-roll is encased with buffer rings. The buffer rings have a long service life, increase friction to the conveyor belt and are shock-absorbent. In order to adjust the belt steering system to a variety of plant conditions, the controlling elements [P und I] are parameterized. This requires the use of the EMSYS parameterizing device. The steering idler generates and stores the required energy and establishes the belt velocity which is a supplementary control parameter. The stored energy is designated for tests, set-ups and communication, also during stoppages. The chassis is adjustable in height and serves the accommo- dation and useful alignment of components and contributes to the overall simple installation of the BSG.
