Cap Orienting
Request More Information ›Zalkin cap sorting equipment is designed to ensure caps are precisely positioned for efficient application to rotary monobloc turrets, rotary freestanding or single-head capping machines. By aligning closures correctly with the container neck, these systems streamline the capping process and enhance productivity.
We offer space-efficient, stainless steel waterfall and rotary cap sorters to accommodate a wide variety of cap types, sizes and geometries, as well as speed requirements, optimizing the efficiency of your production line.
A waterfall cap sorter uses inclined cleated belts and the “center of gravity” principle to properly align caps and then supply them via a single file cap chute to the capping machine. Each waterfall cap orienter can be customized to fit site constraints or production line layouts.
A rotary cap sorter uses combinations of centrifugal force, compressed air and creative geometry to align caps and then supply them via a single file cap chute to the cap applicator/dispenser. Many configurations of rotary orienters are available to accommodate various closures.
Each series is changeover capable and available in turret-mounted or floor-stand-mounted configurations.
When you choose a Zalkin cap sorter — waterfall or rotary — you're investing in equipment sustainability and unmatched performance. Every system component is best-in-class, engineered to seamlessly work together and meet or exceed your expectations.
Our capping orientation systems are used around the world for screw-on, roll-on, push-in and snap-on closures in multiple industries, including:
- PET bottled water
- Carbonated soft drinks (PET & aluminum bottles)
- Non-carbonated soft drinks
- Food
- Dairy
- Distilled spirits
- Beer (aluminum bottles)
- Wine
- Pharmaceutical
- Personal care
- Household products
- Chemical
Our OPPTI.SELECT product line features four types of waterfall and rotary cap sorting machines to handle virtually any closure style or size, including:
CA 12 Model
- Rotary cap orienter
- Designed for speeds up to 416 cpm (25,000 cph)
- Ideal for orienting caps with diameters greater than their heights
- Uses a simple mechanical design and principles of operation to correctly orient caps as they exit the rotating hopper bin, no electronic sensors and no compressed air required
- Once aligned, caps move through the discharge opening into a single-file chute, feeding into the capping system
- Misaligned caps continue rotating in the hopper until correctly oriented
High-Speed GC Series
- Rotary cap orienter
- The cap orienter of choice for high-speed production, the GC Series includes two primary models: the GC3 and the GC12
- Designed for speeds ranging from around 580 cpm to 1,500 cpm (35,000 cph to 90,000 cph)
- Ideal for sorting caps with diameters greater than their heights
- The GC3 model requires a pre-feeding system and plant-supplied compressed air, although its energy efficiency means reduced air consumption
- Soundproofing options to reduce noise to below 85 db
Waterfall Elevator/Orienter
- Waterfall equipment featuring cap elevating and orienting functions
- Designed for speeds up to 800 cpm (48,000 cph)
- Ideal for round caps with diameters greater than their heights
- Uses cleated belts and gravity to ensure caps are correctly positioned for smooth application at the capping heads and to reduce marks or scratches on the caps
- Integrated ionization system to remove dust particles and optional suction system
- Outfeed recycling device in case of cap overloading
Universal Range
- Rotary cap orienter
- The Universal Range features 6 sizes: U500, U750, U1000, U1200, U1500 and U2000
- Designed for speeds up to 1,000 cpm (60,000 cph)
- Ideal for orienting round caps with diameters greater than their heights
- Cap selection step utilizes sequential pneumatic ejection controlled by an electronic sensor
- A rotating disk with pockets captures each closure, while compressed air and vacuum assist in the operation of Universal Range orienters
- The rotating disk pockets capture correctly oriented caps and discharge them into a single file chute
- Misaligned caps are ejected by compressed air and continue rotating in the hopper until properly positioned in a pocket
- Optional quick-release disc segment available for tool-less quick cap changeovers
Our PRO.SELECT eco-friendly packaging machines for cap orienting offer cost and energy savings, with impressive flexibility to seamlessly integrate with existing equipment.
