While different cap types and sizes are seemingly unlimited, it requires a surprisingly low quantity of capping machines to pay for most of caps. Naturally, unique and rare container tops may require custom capping machinery. For most other caps, a tiny band of capping machines will “seal” the offer.
SPINDLE CAPPERS. Spindle capping machines are one of the most popular capping machine produced for the packaging industry. These cappers use sets of matched discs to spin caps down onto bottles or another containers while they go through the capping area on the conveyor system. Normally, three to four groups of discs will be utilized to gradually tighten caps. Elevators or vibratory bowls assist these continuous capping machines by delivering caps to every individual bottle, leaving the operator in the machine to simply replace bulk caps when needed. These capping machines are prepared for many screw type caps, including flat caps, sports caps, trigger sprayers and others. Numerous containers, including F-style containers (imagine anti-freeze, a protracted narrow container having a handle), may be run using the spindle capper and multiple containers require minimal changeover. The versatility and easy operation are two factors that will make this capping machine popular.
CHUCK CAPPERS. Chuck capping machines act like spindle cappers because they help screw caps. Chuck cappers normally consist of a metal chuck along with a rubber insert matched towards the cap size. Each bottle is place underneath the capping head, the chuck descends to use 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 will most likely cap one bottle at a time. While one chuck and chuck insert are prepared for different cap sizes, a center running both large and small caps may need multiple chucks and/or chuck inserts. Chuck cappers are ideal for flat caps, but some modification to the chuck and inserts accommodate other screw type caps to be run as well.
SNAP CAPPERS AND LID PRESSERS. Snap cappers and lid pressers are employed for non-screw type tops. As opposed to being torqued to the bottle, snap type tops are simply applied using pressure and normally held in place by a lip for the container. Pressure to succeed is applied by way of a declined belt or perhaps a simple plunger based on the application. Paint cans may work well inside a lid presser, while plastic containers for a few food and beverage products would make use of a press on belt to avoid damaging the containers themselves. Snap cappers could be constructed very similar to spindle cappers, with all the spindle sets replaced by the decline belt, allowing snap caps to become sealed continuously also, caps permitting. Spindle cappers and snap cappers can also be combined one capping machine to deal with a good wider range of cap types and sizes.
Each one of the capping machines discussed briefly above can be bought in different levels of automation, allowing this group of packaging machines to handle not just a wide range of caps and bottles, however a variety of production levels too.
