How to Operate Automatic and Semi-Automatic Capping Machines

For businesses both large and small, capping machines play a critical role in the packaging process by ensuring that all types of containers are sealed consistently and efficiently, protecting both the liquids in the containers and the consumers that buy them. Understanding the difference between the operation of both automatic and semi-automatic capping machines can help a business choose the right level of automation to meet their own needs.

The main differences between Liquid Packaging Solutions semi-automatic and automatic bottle capping machine operations stem from the bottle movement and the delivery of the cap. Semi-automatic capping machines will require more interaction from the operator of the machine for each bottle and cap. By using a conveyor system and a cap delivery system, automatic cappers typically require initial setup and then simple monitoring by the operator of the equipment. Below we will look at the typical steps for operating each type of capper in more detail, though some steps may differ for specific capping machines.

Operating a Semi-Automatic Capping Machine

• Make mechanical adjustments for bottle and cap to be run.
• Place the filled container on the slide track.
• Place the closure on the bottle or other container.
• Position the container and cap under the capping head.
• Activate the capping machine via foot or finger switch.
• Allow the machine to secure the closure.
• Remove the sealed container and repeat the process.

Operating an Automatic Capping Machine

• Make mechanical adjustments for bottle and cap to be run.
• Load caps into hopper for cap delivery system.
• Start the conveyor, cap delivery system, and capping machine.
• Monitor the cap delivery and availability, add bulk closures as necessary.
• If necessary, adjust machine for speed or cap alignment.

While automatic capping machines are manufactured to seal a higher number of bottles throughout the production day with less interaction from a human operator, the semi-automatic capper models offer the consistency and reliability expected from LPS capping machines. Semi-automatic equipment can range from tabletop models for packagers with little production space to full-frame models for those businesses that expect growth or the need for additional automation as the product line or customer base grows.

Of course, capping machines are also built specifically for the type of closure being used for any given packaging project. LPS manufactures spindle and chuck capping machines for screw-on type, continuous thread closures, corking machines for those using T-corks or other cork-like closures, snap cappers for snap on lids, and ROPP capping machines for aluminum blanks that are threaded to the bottle during the capping process. Custom capping machines are also available for custom closures or containers, such as clamshells, which are not a common seal type.

As noted, the actual operation sequence will vary slightly depending on which type of the above capping machine is used for the sealing process. To learn more about any of the equipment manufactured by LPS, browse the specific products on the website or contact one of our Capping Specialists today!
