While different cap types and sizes are seemingly unlimited, it will take a surprisingly low number of capping machines to pay a majority of caps. Needless to say, unique and rare container tops may necessitate custom capping machinery. For some other caps, a small number of capping machines will “seal” the deal.
SPINDLE CAPPERS. Spindle capping machines are probably the most widely used capping machine produced to the packaging industry. These cappers use teams of matched discs to spin caps down onto bottles or another containers since they move through the capping area over a conveyor system. Normally, 3 to 4 sets of discs will probably be employed to gradually tighten caps. Elevators or vibratory bowls assist these continuous capping machines by delivering caps to each and every individual bottle, leaving the operator with the machine to simply replace bulk caps if required. These capping machines are prepared for many screw type caps, including flat caps, sports caps, trigger sprayers and much more. Many different containers, including F-style containers (think about anti-freeze, an extended narrow container using a handle), can be operate on the spindle capper and multiple containers require minimal changeover. The flexibility and easy operation are two factors that produce this capping machine popular.
CHUCK CAPPERS. Chuck capping machines are like spindle cappers in that they work with screw caps. Chuck cappers normally incorporate steel chuck along with a rubber insert matched towards the cap size. When a bottle is in place within the capping head, the chuck descends to use consistent torque to each bottle and cap combination. Automatic chuck cappers may include multiple chucks to raise the capping machine speed. Handheld, semi-automatic and tabletop chuck cappers will usually cap one bottle at any given time. While one chuck and chuck insert are designed for different cap sizes, a facility running both minor and major caps may require multiple chucks and/or chuck inserts. Chuck cappers are best for flat caps, however, many modification to the chuck and inserts permit other screw type caps to become run too.
SNAP CAPPERS AND LID PRESSERS. Snap cappers and lid pressers tend to be utilized for non-screw type tops. As an alternative to being torqued on top of the bottle, snap type tops are merely applied using pressure and normally held in place with a lip on the container. The pressure is used by way of a declined belt or even a simple plunger with respect to the application. Paint cans may work well in the lid presser, while plastic containers for many food and beverage products would make use of a press on belt to stop damaging the containers themselves. Snap cappers may be constructed very like spindle cappers, together with the spindle sets replaced by the decline belt, allowing snap caps to get sealed continuously at the same time, caps permitting. Spindle cappers and snap cappers can be combined on one capping machine to handle an even wider selection of cap types and sizes.
Each one of the capping machines discussed briefly above can be purchased in different amounts of automation, allowing this band of packaging machines to take care of not really a wide array of caps and bottles, however a range of production levels too.
