The Importance of Annual Mechanical Maintenance Checks for Seamers

Regular can-seamer maintenance is critical to ensuring the optimal performance and longevity of your can seamer. A well-maintained machine not only minimizes downtime but also helps avoid costly repairs and production losses. Annual mechanical maintenance checks are essential to keep your can seamer in top working condition. Below is a breakdown of key areas to focus on during these routine inspections.

Lower Chuck Assembly

The Lower Chuck Assembly plays a crucial role in the seaming process. Here’s what to check:

• Check Spring Pressure: The Lower Chuck Spring must be set correctly and adjusted according to the can manufacturer’s specifications.
• Verify Lower Lifter Plane: Ensure the Lower Chuck Plate dimensions are within .002 of an inch across all plates using a dial indicator for precise measurements.
• Adjust the Drop-Off: Measure the drop-off from the Lower Chuck Plate to the Can Feed Table Wear Plate. This should be set to a .010-inch drop-off using 22L816 Shims for optimal performance.
• Pin Height Adjustment: Pin Height between the Lower Chuck Plate and the Seaming Chuck must be checked and adjusted +- .002.

Feed Turret

The Feed Turret ensures smooth can handling and efficient operation. Here’s what to focus on:

• Clean and Inspect the Turret: Remove the Undercover Gassing Feed Turret following the steps in the Service Manual. Separate the plate and clean the inside thoroughly.
• Distribution Ring Inspection: Inspect the Manifold Ring Assembly for any signs of wear or cracks that will contribute to higher gas consumption.
• Inspect the Oil Seal: Make sure the Oil Seal in the Plate is in good condition to avoid any leaks or inefficiencies.
• Review Conditions of Gas Line: Examine for drying, cracking, or loose connections from the facility connection to the gassing manifold.

Motor Drive Pulleys

Motor Drive Pulleys are responsible for the smooth operation of the seamer. Key checks include:

• Alignment Check: Verify the pulley alignment between the Drive and Driven Pulleys to prevent unnecessary strain on the system.
• Motor Drive Shaft Run-Out: Ensure the Motor Drive Shaft run-out is within the acceptable range to avoid uneven wear.
• Drive Belt Condition: Inspect the Drive Belts for cracks or any signs of wear. Replace as necessary.
• Secure Fasteners: Tighten all fasteners and taper locks that hold the pulleys to the shafting to prevent loosening during operation.

In-Motion Timer & Clutch Assembly

The Clutch and Timer Housing ensure precise control during operation. To keep these components in good shape:

• Inspect Clutch Housing: Remove the Filler Clutch Cover and check the gap between the clutch plates (reference OEM specifications), as well as any signs of wear.
• Check Clutch Coil Resistance: Unplug the electrical connector and test the resistance between the Clutch Coil terminals. It should read between 11 and 13 ohms.
• Lubrication: Ensure all pipe fittings are secure and tight and confirm no oil is passing through seals on entire drive.
• In-Motion Timer Adjustment: Confirm that you are able to advance and retard the filler using in-motion timer.
• Timing: Verify the transfer point from filler to seamer feedchain is timed properly based on the centerline of the filler.

Cover Feed System

Ensure smooth lid handling by inspecting the following:

• Separator Disc & Knife Condition: Check the Separator Disc, Knife, Bearings, Seals, and O-Rings for wear.

Conclusion

Regular annual maintenance checks of your can seamer’s critical components can save time, money, and headaches in the long run. By following these steps and using the detailed guidelines in your Service Manual, you can ensure your seamer operates at peak efficiency, reducing the risk of costly downtime and production errors.

For expert assistance, don’t hesitate to contact a certified seamer technician for audits and repairs to keep your machine running smoothly.
