New to Teledyne’s line of on-line inspection systems, the TapTone Seal Integrity Tester (SIT) is a patented design that consists of multiple sensors mounted inside the cup filling system that inspect each cup by compressing the sensor head to the foil lid of the cup at full production machine speeds (200ms and higher). The sensors monitor the lid deflection during the compression cycle and the digital signal processor board calculates the inspection merit values to accept or to reject containers with defective seals that fall outside user set merit value limits. The system can detect bad seals caused by product across the seal area during filling, deformed or damaged foil lids that cannot make a good seal, and weak seals that can be caused by a variety of issues including out of range heater temperatures.
Using state of the art DSP processor technology, the patented SIT sensor incorporates an easy to use PC user interface graphically displaying “good” non-leaking cups in green and “bad” leaking cups in red. Minimum leak detection specifications for the SIT system range from 0.006-0.008 in. (150-200 microns) with multiple inspection algorithms capable of not only seal integrity but also gross leaks and missing foil detection. The SIT system can integrate into an existing filler PLC using Ethernet Modbus TCP/IP or Ethernet IP and sensors that mount to a vertical travel bridge after the sealing heads in your filler/sealer system. The bridge will cycle up and down based on your filler index speed. Bridge control will come directly from your filler PLC for perfect index timing.
