  • Page 3: Dud Inspection Overview

    Dud Inspection Overview Dud inspection detects improperly sealed vacuum or pressure sealed containers. If the container is not sealed properly, the container shape is distorted and the dimensions at the inspection reference point will deviate from a correctly sealed container. When inspecting cans the reference point is the lid and when inspecting bottles the reference point is the cap seal button.
  • Page 4 As the container passes under the proximity sensor the sensor determines if the seal is intact based on the distance between the sensor and the top surface of the lid or cap. If the lid or cap is too far from the sensor, the pressure seal is not intact because the cap is not raised high enough by the container pressure.

  • Page 5: Container Changeover

    Container Changeover When changing to a container type that does not require dud inspection: 1. Press Key 5 until Dud Status appears and press the Arrow Key to turn dud inspection off. 2. Perform the container fill level changeover as explained in the inspection unit Operation Guide.

  • Page 6: Dud Inspection Sensor Alignment

    Dud Inspection Sensor Alignment Before you align the dud sensor you must configure the inspection head and inspection trigger to the proper height for fill level inspection and calibrate the fill level inspection. Align the dud sensor immediately after all fill level inspection adjustments are complete.
  • Page 7 5. Unlock the dud sensor height adjustment mechanism and adjust the height of the sensor so the sensor’s face is 3/32 ±1/32 inch [3 ±1 mm] above the container. Description Height Adjustment Locking Lever Bracket Pivot Hinge allows deflection if hit by container. 3/32 inch [3mm] space between can rim or bottle cap.
  • Page 8 6. Verify the dud sensor face is parallel to the top of the can. If necessary, use the adjusting screw to change the angle. When complete, tighten the adjusting screw and its locknut securely. Description Bracket Pivot Hinge Bracket Leveling Adjustment Screw Bracket is parallel with lid or cap Direction of container flow Figure 4.
  • Page 9 11.Unlock the inspection (centerline) trigger adjustment mechanism and raise or lower the sensor very slightly until reading is between: • 120-140 for cans • 70-90 for bottles Record the position of the trigger on the trigger height scale for ease of future container changeovers.

  • Page 10: Dud Inspection Software Setup

    Dud Inspection Software Setup Note: Turning the Beacon Status is on while setting up the dud inspection enables low priority diagnostic messages, that can help provide feedback about errors that can occur during the setup procedure. 1. Align the dud sensor. For more information see Dud Inspection Sensor Alignment on page 4.
  • Page 11 4. Depending on the type of container you are inspecting, proceed as follows: • If you are inspecting bottles, proceed to step 5 on page 9 to determine the dud reference points for cap inspection. When finished proceed to step 9 on page •...
  • Page 12 6. Multiply the measurement from step 5 on page 9 by two (2) to calculate the Diameter of Dud Reference Points. Measurement (mm) x 2 = Diameter of Dud Ref. Points 7. Press Key 2 until Diameter of Dud Reference Points appears and use the Arrow Key to enter the value you calculate in step...
  • Page 13 11.With the conveyor running, place a good container on the conveyor upstream of the inspection head. As the container passes under the dud sensor, verify the beacon does not light. • If there are no errors, pass 4 more good containers through the inspection head.

  • Page 14: How To Create A Dud Container

    How to Create a Dud Container The calibration and testing procedures used to setup dud inspection require you to create or acquire at least four (4) bad containers. Depending upon the type of container you are inspection you will need to create dud cans or dud bottles. Creating a Dud Can To create a dud can puncture the can just below the lid seam and allow the pressure to dissipate.

  • Page 15: Dud Software Advanced Functions

    Dud Software Advanced Functions The FT-50/70 includes special advanced functions that enable you to configure the dud inspection parameters. These functions are accessed through the following control panel keys: Key 2: Can Finish Dud Status Enables or disables dud inspection. When disabled all dud inspection functions deactivated and will not appear in the software menus.
  • Page 16 This function may also reject the container following a bulged can or high cap that strikes the sensor bracket and the container r passes under the sensor before bracket returns to position. If your system contains a bulged can, raised can, or high cap inspection, the dud inspection software will not increment the undefined (dud) reject counter.
  • Page 17 Calibrate Dud Automatically calibrates the dud inspection and calculates the reference and inspection diameters, Container Threshold and the Container Inspection Window Threshold. You need 1 good container and 1 bad container to execute the routine properly. A good container must be run 5 times and the bad container run 4 times.
  • Page 18 Dud Data Length and Values The inspection buffer length, the inspection points and their positions or offsets in the buffer. This display is used to help determine if the automatic centering methods of necked-in or chines are working. All values range from 0 to 255. This system is set up properly if the average of the positions of reference 1 and 2 are in the middle of the buffer length.
  • Page 19 Total Dud High Threshold The total number of containers that were rejected as duds since the last time the counter was reset. This includes the total of all cans that were detected above the Dud High Threshold. (Range: 0 To 99,999,999) Total Undefined (Dud) The total number of containers that were rejected by dud inspection for undefined faults that interfered with dud...
  • Page 20 Defines the number of consecutive dud rejects that will trigger an alarm condition. Rejects must be consecutive. Each good bottle, for this condition, that passes through the FT-50/70 will reset the counter to zero. (Range: OFF, 1-250, Default: OFF) Alarm Undefined (Dud) Dud Undefined status turns off rejection of undefined dud inspection and deactivates all undefined dud software functions.
  • Page 21 Error Number 95 Dud reference readings are too dissimilar. Can be caused by High cap or Skewed cap. Verify sensor is parallel and centered over cap. Error Number 96 Calculated inspection window threshold too small. Readjust dud sensor height and check A/D card configuration. Error Number 97 Difference between Good and Bad Duds is less than 10.
  • Page 22 Error Number 111 Dud inspection windows length exceeded. Lower the Gamma Sample Cutoff Limit or verify Container Width at Trigger. Then perform Dud Calibrate. Error Number 112 Dud reference diameter calibrated larger than inspection window. Reduced reference diameter and verify container width at trigger.

  • Page 24: Troubleshooting

    Troubleshooting 1. Is the dud inspection activated? Press Key 2 until Dud Status appears and verify the status is turned on. If not, press the Arrow Key until appears. Dud inspection is now activated. 2. Run a sample of good and bad containers through the inspection system.
  • Page 25 6. If too many false rejects or false accepts still occur, the Container Threshold may be incorrect. This may be caused by calibrating the system with containers which are not repre- sentative of the container population. Adjust the value as explained below: Excessive False Rejects Excessive False Accepts...
