- Then press the ok button after the screen shows “Model Teaching Complete.”
- The main window will appear, click on the option “Inspection,” enter the batch number, press “enter,” and click on the “start” button to start the inspection.
- After this camera will start the inspection, count the number of blisters in one track from the camera scanning head to the punching tool, and enter the count in the BQS machine MMI to reject the camera-rejected blister.
- Clean the MMI of the camera vision system and its inspection hood with a dry lint-free cloth after completion of the operation.
Procedure for Camera Challenge Test:
Frequency:
- At the start of the batch
- After every break
- At the end of the Shift
- End of the batch.
Procedure:
- Start the blistering operation as per sop “operation and cleaning of blister packing machine.” remove one tablet from the web from one representative unit blister (which corresponds to the respective track) before the inspection.
- Ensure that the respective blisters should be shown as rejected on the PLC of the camera when inspection.
- Ensure that the respective blister should be rejected physically at the punching station.
- Mark the tablet with the help of a black permanent marker and put it on the web for the challenge of foreign particles.
- Break the tablet and put it on the web for the challenge of the Broken tablet.
- Discolor the tablets with the help of a red marker and put them on the web for the challenge of discoloring tablets.
- Ensure that the respective blisters should be shown as rejected on the PLC of the camera while inspection.
- Ensure that the respective blister should be rejected physically at the punching station.
- Record the observation in BPR.
- If the camera vision system is failing for the in-process checks, stop the machine and quarantine the quantity packed between the last satisfactory test and the present unsatisfactory test and put an appropriate status label on it.
- Rise the deviation and inform to engineering department through the maintenance Requisition slip (MRS) for the same if required.
- After rectification of the fault, carry out the in-process check of the camera vision system and record the observation in the BPR, and attach the annexure.
- Re-open all the cartons that are quarantined and recheck all the blisters visually in the case of transparent PVC / pvdc/foil and by weight in the case of the PVC/ PVDC/ Aluminium foil.
Procedure for setting operation and cleaning of pinhole detector :
PINHOLE DETECTOR
- Fixes the intermediate holding plate for the guide track below the track.
- Ensure that the detection slot of the guide track and holding plate exactly coincide with each other.
- Place the transmitter unit on the guide track.
- Holding the receiver plate below the guide track.
- Connect the 10-pin D-connector cable to the connector fix on the transmitter.
- Switch “on” the power supply to the pinhole detector.
- Adjust the sensitivity of the pin holder detector, switch on the pinhole detector unit, and bring the numeric display mode on a screen.
- Ensure that the noise value displayed on the screen is as low as possible, ideally less than 300mv.
- Ensure that the shoulder level is to be approximately twice the noise value.
- Ensure that before starting the operation, the equipment is free from any foreign particles.
- Ensure that the transmitter and receiver unit are properly connected for the smooth flow of the product.
- Ensure the proper detection of any pinhole/tear/crack in the product.
- To adjust the threshold setting, Press the “edit” tab in the MMI of the blister packing machine.
- Press the “special function” Tab after pressing the “next “ tab.
- Press the “^” tab and then enter recipe” followed by “edit file.”
- Press the “v” tab and enter the count from the pinhole detector head to the punching tool in pinhole rejection offset.
- “load” tab after pressing the “save” tab.
- Clean the receiver detection slot with a dry lint-free cloth or soft brush to avoid the accumulation of dust on the screening slot after the completion of the batch.
Frequency:
- Test to be conducted for Alu-Alu base foil only at the start of the batch.
- At the end of the Shift.
- At the start of the Shift.
- At the end of the batch.
- There should be a Red Light glow on the pinhole detector when there is no fill-in pinhole detector and ensure the free moment of the Foil.
- Set the THR value three by using the upper Arrow and lower Arrow keys and press enter after selecting the value.
- Place that standard kit 100 Micron in between the pinhole detector.
- Pass the standard kit to the left-hand side slowly. Initially, when a standard kit of 100 Micron passes through the pinhole detector, the indicator should not light up.
- When the pinhole detector detects a 100 Micron pinhole, the red light on the pinhole detector should glow.
- If the result is satisfactory, proceed with the next steps. If the result is not satisfactory, recheck the settings of the pinhole detector and perform the challenge test again.
- Set the blister count from the pinhole detector to the punching station, make some pinhole/tear/ crack manually by using scissors in any one blister and check for detection of the same, and ensure that blister should be rejected at the punching station. It should be done to check the count of the blister.
- Check for the operation of the pinhole through PLC.
- Ensure the rejected blister gets collected in the rejection box.
- Start the operation only after satisfaction that found.
- Carry out the challenge test of the pinhole detector and record the observation in the annexure (if the challenge test passes right “ok” and if it fails right not ok).
- If the pinhole detector fails for the in-process check, then stop the machine and quarantine the quantity pack between the last satisfactory test and the present unsatisfactory test and put an appropriate status level on it.
- Rise the deviation and inform to engineering department through maintenance requisition slip for the same if required.
- After rectification of the fault, carry out a challenge test for the pinhole detector system and record the observation in the respective annexure (if the challenge test passes right ok and if it fails right not ok).
