Counting Machine Options & System Enhancements

• 16 Infrared LED’s with 46 individual scan paths that are scanned every millisecond giving 46,000 scans per second.

• Multi LED analysis the system will detect chips and partial tablets with much higher accuracy than standard infrared systems and track identified chips etc into a bottle for rejection.

• “Onboard” microprocessor monitors and trends output power to optimise performance.

• No calibration required.

• Automatic learn process to determine minimum and maximum dark time setup and HD detects.

• Individual LED analysis with histogram records to determine typical beam disrupt.

Gross weigh systems will weigh filled bottles to confirm that the combined weight of the pack and products is within the expected range for the configuration. Where there is a nonconformance the bottle is rejected from the line.

The limitations of gross weigh only is that bottle weights will have a standard deviation as will the product so these need to allowed in the target weight range to avoid false rejects.

Tare/Gross systems offer a higher level of control as the system allows weighing of the empty bottle before filling with products and this value is recorded and retained within the system. The bottle is now indexed to the filling position where the tablets are dispensed and on completion of filling the bottles are indexed to another weighing station where the filled weight is captured. The system will now deduct the empty bottle weight from the total weight and so allow the weight of the product only to be compared to and expected target.

This method allows higher accuracy as the bottle weight variation (far greater deviation than tablet weight) to be excluded from the calculations.

Standard container gating systems comprise of pneumatic two position gating systems that allow bottles to be introduced to the filling position and retained in position by the first stainless steel gate. On confirmation that filling is complete the first and second gates will reverse position to allow a filled bottle to be released downstream whist presenting the next empty bottle for filling.

Timing Screw Drive indexing systems allow fast and accurate positioning of bottles under the filling position but has the added advantage of allowing bottles to be positioned with different pitch centres which can be an advantage on multifil counters as it allows all fill positions to have the same filling profile and as such maximise the line speed. PPS use VEE profiles scrolls which allows more than one bottle size to run on the same profile and as such reduces changeparts and respective changeover times too.
