Parameter monitoring of continuous loop strap for cable ties

Cable ties in the most variegated shapes and continuous loop straps for  automated applications are manufactured in the fastening technology and  cable management industry. In practice, the continuous loop strap and  fastening heads are combined from their separate dispensing devices.  The strap is guided around the item to be bound and cut to length, and  the fastening head is added from the dispenser and connected to the  strap. It is essential that the “width” and “height” of the cable tie strap, as  well as the “tooth pitch” are monitored concurrently and constantly during  the production of the continuous loop straps.  These values are crucial to ensure a consistently good and reliable  binding result. Monitoring of specific product parameters during the entire  process is pivotal in ensuring the quality and uniformity of production.  HellermannTyton GmbH therefore relies on a solution from ISW GmbH  that uses a Micro Epsilon sensor system to monitor the parameters. The solution consists of a sensor combination that includes two optical  precision micrometers and a triangulation sensor that is attached  behind the extruder. Two ODC 2520-46 type sensors are positioned both  horizontally and vertically and measure the height and width of the strap.  The optoNCDT ILD2300-2DR series triangulation sensor measures the  tooth pitch from above. ISW GmbH implemented the arrangement of  the sensors in a compact structure with adjustable strap guiding. The  data measured are analyzed using the interface programmed by Micro  Epsilon system partner ISW GmbH via a port. Recording the extrusion  speed is the challenge in this application. The speed must be congruent  with the measuring sensors.  The combined measuring system, consisting of optoCONTROL and  optoNCDT, provides extremely reliable and reproducible  measurements. In the final analysis, this accelerates the optimization process, and reduces waste and errors  during manufacturing.
