While different cap types and sizes are seemingly unlimited, it will require a surprisingly low variety of capping machines to cover most caps. Obviously, unique and rare container tops might require custom capping machinery. For some other caps, a tiny band of capping machines will “seal” the deal.
SPINDLE CAPPERS. Spindle capping machines are the hottest capping machine produced to the packaging industry. These cappers use sets of matched discs to spin caps down onto bottles and other containers since they move across the capping area on a conveyor system. Normally, three to four sets of discs will be employed to gradually tighten caps. Elevators or vibratory bowls assist these continuous capping machines by delivering caps to each individual bottle, leaving the operator with the machine to merely replace bulk caps if required. These capping machines can handle many screw type caps, including flat caps, sports caps, trigger sprayers and much more. A variety of containers, including F-style containers (think of anti-freeze, a lengthy narrow container which has a handle), may be run using the spindle capper and multiple containers require minimal changeover. The versatility and ease of operation are a couple of factors that produce this capping machine popular.
CHUCK CAPPERS. Chuck capping machines are similar to spindle cappers in this they assist screw caps. Chuck cappers normally incorporate a metallic chuck as well as a rubber insert matched for the cap size. Once a bottle is place under the capping head, the chuck descends to make use of consistent torque to every one bottle and cap combination. Automatic chuck cappers may include multiple chucks to improve the capping machine speed. Handheld, semi-automatic and tabletop chuck cappers will often cap one bottle at the same time. While one chuck and chuck insert are equipped for different cap sizes, a center running both large and small caps might require multiple chucks and/or chuck inserts. Chuck cappers are fantastic for flat caps, but some modification for the chuck and inserts accommodate other screw type caps to get run also.
SNAP CAPPERS AND LID PRESSERS. Snap cappers and lid pressers are both employed for non-screw type tops. As opposed to being torqued to the bottle, snap type tops are simply applied using pressure and normally locked in place with a lip on the container. The pressure is applied via a declined belt or perhaps a simple plunger with respect to the application. Paint cans may fit well in a lid presser, while plastic containers for a lot of food and beverage products would use a press on belt to prevent damaging the containers themselves. Snap cappers can be constructed very similar to spindle cappers, using the spindle sets replaced by the decline belt, allowing snap caps being sealed continuously also, caps permitting. Spindle cappers and snap cappers can even be combined on one capping machine to take care of an even wider array of cap types and sizes.
Every one of the capping machines discussed briefly above are available in different degrees of automation, allowing this band of packaging machines to deal with not really a wide array of caps and bottles, however a array of production levels too.
