While different cap sizes and types are seemingly unlimited, it will take a surprisingly low variety of capping machines to pay most of caps. Obviously, unique and rare container tops may need custom capping machinery. For almost all other caps, a smaller band of capping machines will “seal” the sale.
SPINDLE CAPPERS. Spindle capping machines are the hottest capping machine produced for the packaging industry. These cappers use groups of matched discs to spin caps down onto bottles or another containers as they move across the capping area on a conveyor system. Normally, 3 to 4 multiple discs will probably be used to gradually tighten caps. Elevators or vibratory bowls assist these continuous capping machines by delivering caps to each individual bottle, leaving the operator of the machine to easily replace bulk caps as required. These capping machines are designed for many screw type caps, including flat caps, sports caps, trigger sprayers and others. Many different containers, including F-style containers (consider anti-freeze, a long narrow container with a handle), could be run on the spindle capper and multiple containers require minimal changeover. The versatility and easy operation are a couple of factors that produce this capping machine popular.
CHUCK CAPPERS. Chuck capping machines act like spindle cappers in this they use screw caps. Chuck cappers normally contain a metallic chuck along with a rubber insert matched for the cap size. When a bottle is place beneath the capping head, the chuck descends to apply consistent torque to every one bottle and cap combination. Automatic chuck cappers might include multiple chucks to increase the capping machine speed. Handheld, semi-automatic and tabletop chuck cappers in most cases cap one bottle during a period. While one chuck and chuck insert are designed for different cap sizes, a facility running both small and large caps may require multiple chucks and/or chuck inserts. Chuck cappers are perfect for flat caps, but some modification for the chuck and inserts accommodate other screw type caps to get run as well.
SNAP CAPPERS AND LID PRESSERS. Snap cappers and lid pressers are used for non-screw type tops. As an alternative to being torqued onto the bottle, snap type tops are simply just applied using pressure and normally held in place with a lip around the container. The pressure is used with a declined belt or perhaps a simple plunger depending on the application. Paint cans may go well within a lid presser, while plastic containers for many food and beverage products would utilize a press on belt in order to avoid damaging the containers themselves. Snap cappers may be constructed very like spindle cappers, with the spindle sets substituted with the decline belt, allowing snap caps to become sealed continuously too, caps permitting. Spindle cappers and snap cappers may also be combined one capping machine to manage an even wider selection of cap types and sizes.
Each one of the capping machines discussed briefly above are available in different levels of automation, allowing this band of packaging machines to handle not really a wide array of caps and bottles, however a array of production levels also.
