We produce a range of belt tracking systems designed to correct the lateral movement of steel belts under different environmental, loading and running conditions.
Spring Loaded Guide Rollers (SLGR)
The benefit of the SLGR tracking system is its simplicity. It is well suited to less complex conveyor applications or applications where the belt is operating in extreme environments. There are no electronics, few moving parts and it is easily mounted to an existing conveyor frame with little modification.
The AT unit is an active tracking system that angles the drum to create the desired belt tracking motion. Installation of AT is best suited to cases where an end station is being replaced or can be rebuilt, or for clean-sheet applications where the conveyor is being designed. The tracking effect is achieved by adjusting the position for one of the drum bearing boxes longitudinally along the belt length. Note that belt running direction does not influence the tracking effect: the belt moves towards the side with the lowest tension. Tracking starts when one of the edge sensors is activated by the belt edge. The tracking cycle is a pre-defined sequence that can be adjusted according to actual conditions.
Where active tracking is required on an existing conveyor and a rebuild is not practical, an IPCO tilt roller tracking system provides an effective solution. These units can be mounted in a variety of positions to an existing conveyor and in most cases little modification is required to accommodate them. The tracking effect is achieved by tilting (lifting one edge of) the belt, causing the belt to move laterally in the appropriate direction. Belt running direction influences the tracking effect: the belt moves to the side with the lowest tension. When the belt edge is activating an edge sensor, a small logic relay controls the tilting in a pre-defined sequence that can be adjusted according to actual conditions.
This stable and proven system provides pneumatic belt tracking control and belt tensioning, and can be used to correct belt misalignment on steel belts with and without V-ropes. Real time detection of the position of the steel belt edge from one side is achieved by means of a contactless inductive sensor. This triggers an analog signal from the sensor, which actuates any necessary correction in the electro-magnetic positioner.
The latest addition to our range of tracking solutions is the High Precision Tracking system. Originally designed for the digital printing segment, it can be used in any application where high precision is required. Besides delivering the most tightly controlled tracking of all the standard solutions, the HPT also serves as a very simple and precise tensioning system thanks to its integrated load cells. The proprietary electronics package provides precision tracking and tensioning in one compact package.
