Calibration
KL15769 Cannular Compact Semi-Auto Canning Machine | Calibration & Seam Checking
Calibrating To Achieve Correct Double Seam Specification
Ensure the correct chuck for your can ends is installed and tightened - if seaming B64 cans such as all aluminium cans supplied by KegLand then this will already be installed. Unplug the machine before adjusting rollers. The top cover can remain on but removing it may aid access. It is receommended to remove the cover when calibrating. The cover is held in place with 4mm Allen Bolts.
Remember: to check calibration of a Cannular to acheive a hermetic double seam, use calipers to measure the following after the 1st operation (overlap) and both operations (seam width and length):
Actual overlap (>0.4mm)
2nd Op seam thickness (1.2-1.3mm)
2nd Op seam length (2.3-2.4mm)
These three measurements are the best way to determine if the Cannular is correctly calibrated.
For more information and troubleshooting please refer to Calibration Overview
Table Height Adjustment
Warning: Do NOT install any table or table spacer other than the table provided with the KL17879 Semi-Automatic Cannular). A table spacer is not required and should never be used on this model.
Adjusting the table height to suit the cans to be seamed should be performed before calibrating the rollers.
The table height should be adjusted so that the can and end are securely engaged against the chuck when the table is lifted and locked in place. If the can buckles, it is too high. If the can can be moved against the chuck, it is too low
Using an Allen key or steel rod as a lever in the coupling nut, undo the coupling nut on the base of the turn table support by turning anti-clockwise (left to right). Hold the table lever to prevent rotation.
Turn the table support anti-clockwise to raise and clockwise to lower the turn table support.
Loosening coupling nut
Tightening coupling nut
Gradually raise the table until firm pressure holds the can against the chuck. The can should be held firmly but not buckle. Tighten the coupling nut clockwise (right to left) firmly using an Allen key as a lever (above).
Note: The table must be concentric to the chuck in order to acheive a good double seam. If the table requires adjsutment please refer to Table Position Alignment. Typically this is not required - it is extremely rare for the Cannular Table to not be concentric to the chuck out of the box.
Roller Calibration
Once the Table Height has been adjusted and is concentric, then the rollers must be calibrated to the chuck in order to acheive a seam. For a good, hermetic double seam the tolerances are quite tight.
To check calibration it is best to measure the overlap and finished seam as it can be quite difficult to measure gaps accurately using KL13420 feeler gauges
Thus, calibration is performed using feeler gauges to set the gaps between the rollers and the chuck. Seam measurements are used to determine that these have been set correctly.
The below calibration procedure applies to both B64 and VISY chucks. Note that correct calibration is determined by actual seam measurements.
1st Operation Roller Calibration
The right hand roller performs the 1st operation.
Use a KL13420 feeler gauge set for precision.
Always adjust the Y axis/gap first. The X axis/gap will change when the y axis is adjusted
Set The 1st Op Roller Height & Gap (Y-Axis)
Unplug the power from the machine
Turn the chuck clockwise until the 1st operation roller is at its closest position to the chuck. NEVER turn the chuck anticlockwise (risk motor damage)
Note: It is also possible to use the Momentary button to 'nudge' the rollers into place. First, turn the Power Switch off. Then you can use the front, Momentary Switch to nudge the roller until it is in the closest postion to the chuck for calibration
Using a 14 mm spanner or socket, loosen the y-axis adjustment nut as shown
Slide the roller vertically along the drive shaft to set gap Y to 0.05 mm. The 1st operation roller should be as close as possible to the chuck in the y-axis without touching
Measure gap Y from the flat face of the roller to the top of the chuck
You may need to increase the x-gap slightly so the curved face is further from the chuck to measure from the flat face
Tighten the Y-Axis Adjustment Nut firmly once gap Y is correct
Set the 1st op roller gap (x-axis)
With the roller at its closest position to the chuck, loosen the X-Axis Adjustment Nut with a 14 mm spanner or socket
Adjust the roller so gap X between the chuck and the 1st op roller is 0.6 mm ± 0.1 mm. Ensure the feeler gauge is flush with the face of the chuck and placed at the same angle as the chuck when taking the measurement
Tighten the x-axis adjustment nut firmly once the correct gap X is achieved
Note: gap X may change as you tighten the x-axis adjustment nut. To prevent this, tighten the nut from the side of the machine to avoid torquing the arm holding the roller
Note: The X-Axis Adjustment Nut may not provide fine enough adjustment during calibration. For finer adjustments, the detented roller can be used.
Once the 1st Operation Roller has been calibrated, check the actual overlap to ensure it is accurate
2nd Operation Roller Calibration
The left roller performs the 2nd operation. Use the same process as for the 1st Operation Roller to adjust the 2nd Operation Roller.
The required Gap Alignment for the 2nd Operation Roller:
Gap Y for 2nd op: 1.35 mm ± 0.05 mm
Gap X for 2nd op: 0.3 mm ± 0.1 mm
Note: The X-Axis Adjustment Nut may not provide fine enough adjustment during calibration. For finer adjustments, the detented roller can be used.
Once both rollers have been bought into specification, test the seam using the Checking Seam Quality Guide. The required gaps are a guide to getting the rollers into caibration. However, the actual measurements of the seam after the 1st and 2nd Operations are are more reliable method of determining if the rollers are in spec or not. This is largely because it can be quite difficult to accurately assess roller/chuck gaps using feeler gauges.
Fine Adjustments To The X-Axis (Both Operations)
Use the x-axis adjustment nut for large movements. For fine adjustments take advantage of the detented rollers and the roller hex socket.
Loosen the y-axis adjustment nut just enough that the roller is still held in position in the y-axis
Insert a 4 mm Allen key into the hex socket on the underside of the roller and turn counterclockwise slightly to loosen. Do not loosen too far or the roller may fall off
As the hex socket loosens the roller will rotate around the drive shaft and move closer or further from the chuck depending on the shaft position. If the roller does not move, loosen the y-axis nut further
Once the roller is in the correct x-position, confirm gap Y, tighten the y-axis adjustment nut to lock the roller, then tighten the hex socket on the bottom of the roller
Check That The Rollers Spin Freely
Ensure the Allen key bolts on the underside of the rollers are tight, then rotate the rollers by finger to confirm they spin freely without much resistance.
Important: After adjusting, manually turn the chuck clockwise through a full rotation to ensure the rollers never contact the chuck.
After positioning the rollers, assess the actual overlap, seam width and seam height using the Checking Seam Quality Guide) to confirm seam quality and that parameters are within allowable ranges.
