Have you ever wondered how manufacturers secure caps on their bottles? According to Market.us, Coca-Cola sells over one billion bottles of cola every day. That is a lot of bottles, and that is just one major company. The Coca-Cola company, and many other businesses, would not be doing nearly as well without the help of cap closing machines and rotary automation. What is a capping machine?

Cap closing machines seal bottles of all shapes and sizes once full (liquids or solids). Beverage bottles, medicine bottles, and household cleaning products are all manufactured with these machines. The machines carefully line up bottles and lids before placing caps and securing them. A cap closing machine does just what its name implies, but different types of cap closing machines exist to meet the demands of different industries.

Inline Capping is the most used method of adding caps to bottles because it seamlessly works for different caps and containers. The machine also boasts speeds of up to 200 caps per minute (this number depends on the configuration of containers and the size of caps). These systems often use air load clutches or springs to control torque.

Snap Capping is a specialized machine that is almost exclusively used in NEPCO applications. It uses the same principles as an inline capping system, but it applies minimal pressure when securing caps. The system is less expensive than any others because it has few moving parts.

Technology continues to advance without an end to stopping in sight. The manufacturing industry benefits greatly from new advancements in automated technologies. Although the assembly line dates to the turn of the 20th century, significant changes have been made in the industry that has greatly streamlined production, reduced waste, and lowered manufacturing costs. Is your business reaping the benefits of modern automation and cap closing machines?

Automated assembly machines

There are three main benefits found when using modern automated technologies, which include:

Consistent Production Rates– inspection technology and robotic assembly maximize production rate without cutting corners or making consistent errors. Cameras and robot arms detect errors and actively and quickly remove any unfit products from the line before being sorted.

High-Output Volumes – automation assembly machines move quicker than the human hand, they do not need breaks, and they do not need to sleep for 6-8 hours every day. It is nearly impossible to recreate the speed and accuracy of automation with human work. Automated assembly machines reduce the number of employees needed on an assembly line while increasing output and profit.

Savings – the initial cost of designing, building, and installing automated assembly machines and cap closing systems is sometimes considered high. What needs to be remembered that the longer the system is used, the bigger your savings become. Labor costs are amongst the highest a business must cover. With an automated assembly machine, you can hire the proper number of employees to do highly specialized jobs.

Adding cap closing technology to an automated assembly system is highly beneficial, but only when the cap closing machine is set up to the exact specifications of your application.  When designing a system, often, engineers break the design into two basic categories. Rotary chuck cappers and in-line cappers. Both machines are immensely beneficial for improving production speed while reducing manufacturing costs, but they are dramatically different in their core design. Both types are different in the techniques they use to apply and secure closures.

Beyond understanding the difference between machine categories, there are many other considerations when designing cap closing machines. Important considerations include:

Cap Size – An in-line capper system is often limited by the diameter of the cap that can be applied. Ideal capping applications require a large enough diameter of the closer to creating enough torque to safely secure caps.

Cap Shape – Chuck applications process round, square, rectangular, tapered, oval, and tapered caps. In-line systems mostly process round caps

Evident Bands – When TE (tamper evident) is needed, chuck-style systems offer many benefits over in-line capping. When cap closing machines are not properly created, the cap commonly sits crooked. Chuck-style systems deliver a strong, downward force that helps secure the cap and the closure.

Engineering assembly machines require a great deal of problem-solving before the perfect system is built. Trusting professionals when designing automated assembly systems and cap closing machines ensures that your business gets exactly what it needs.

Cap closing machines are essential components of bottling automation. A capping machine’s main function is to apply a metal or plastic thread lid, snap, or caps accurately and securely to a container or bottle. Capp closing machines also process plugs and other similar closures. These systems ensure sanitary workspaces, high production speeds, and affordable manufacturing costs.

Cap Closing Machines

Although each system is customized to meet the needs of specific applications, a traditional capping system contains several key components, which include:

1. Cap Elevator
2. Cap Hopper
3. Cap Sorter

The system starts with a box of closures (caps, plugs, lids, etc.). Through a feeder system, closures are moved into the cap hopper. From here, the cap elevator takes over and begins to feed closures into the sorting bowl. A sorting bowl is used to increase the speed and efficiency of the cap delivery system. When closures are in a sorting bowl, they are oriented before being sent to the capping machine when attached to a container. For certain applications, a cap sorter or hopper can be used to eliminate the need for adding a sorting bowl.

There are two common types of cappers that companies use:

Rotary Chuck

These cappers place caps onto containers and then send the part through the machine to get sealed onto the container. The machine contains moving parts that spin the bottle and cap to create a secure seal. These systems are considered continuous motion assembly machines, which means that the line never stops moving.

Single Head

These cappers are like rotary chuck cappers, but they should not be used interchangeably. A single head capper stops containers at stations to secure caps. These systems are often designed to be inline, but they can also be constructed with a star wheel that takes the cap and bottle off the line to secure before returning the parts back to the line.

Many products that we see and use daily are partially put together using what are known as cap closing machines. They do exactly what their name suggests: the machine is used to affix and tighten caps to bottles and containers. These automated assembly machines are used to apply either metal or plastic threaded caps, snaps, lids, or plugs to another similar closure. This process can be conducted at both low and high speeds (depending on production requirements). Designing and installing cap closing machines are costly upfront, but most businesses quickly see the long-term money and time-saving potentials. Investing in these machines is a real commitment to your business’s future and the health of your employees.

If you consider adding this type of machinery to your production method, you should know that there are four main types of cappers. These include:

1. Rotary chuck cappers place caps onto containers and bottles and then sends the pieces through the machine where the two parts are tightly sealed. This capper type operates continuously, which means that production rates are high and turnaround time is quick.
2. Servo cappers utilize upgraded motors that are designed for efficiency, flexibility, and accuracy. These cappers provide solid spindle control without sacrificing application torque.
3. Single head cappers are like rotary chuck cappers, except that the single head variant stops the bottle at a station to spin. Bottles are kept on the main conveyor, or it is kept with a star wheel that takes bottles of the line and then back.
