The Automatic Cap Sorter & Elevator is an essential upstream component for any automatic capping line. Where manual cap feeding creates inconsistent supply rates and operator fatigue, the cap sorter delivers a continuous stream of correctly oriented caps to the capping machine automatically, at 40–80 caps per minute. The result is a smoother line with fewer stops, lower labor requirements, and capping throughput that keeps pace with your filling and conveying speed.
A large 225-liter bulk hopper accepts a full batch of caps in one load. An internal elevator with a PLC-controlled sorting track lifts caps and screens them against an orientation guide: correctly positioned caps — rim down, top up — proceed along the delivery chute; inverted caps are redirected back into the hopper for re-sorting. This self-correcting mechanism maintains a steady cap supply without jams or manual intervention.
Built by Dongguan Yucheng Machinery Technology Co., Ltd. (YCTAUTO), the cap sorter operates on only 0.2 kW, making it one of the most energy-efficient auxiliary machines in any packaging line. Stainless steel and food-grade construction suits hygienic environments in food, beverage, cosmetic, pharmaceutical, and chemical manufacturing. The Φ40–100 mm cap range covers the vast majority of consumer screw cap sizes, with adjustability for different sizes within that range.
Large 225-Liter Bulk Hopper — Accommodates a full batch of caps in a single load, reducing operator intervention frequency during long production runs — especially valuable on high-speed capping lines.
Automatic Cap Orientation (Top-Up Only) — The PLC-controlled sorting track selects correctly oriented caps (top-up, rim-down) and returns inverted caps to the hopper for re-sorting. No manual orientation required.
40–80 pcs/min Delivery Rate — Matches the cap supply rate of a wide range of downstream capping machines. Delivery speed is adjustable to synchronize with your capping machine output.
Wide Cap Size Compatibility: Φ40–100 mm — Handles the majority of common screw cap and press-on cap sizes used in food, beverage, cosmetic, pharmaceutical, and chemical packaging. Size adjustment is made by changing guide and track components.
Gentle Cap Handling — No Damage — Smooth conveying surfaces and controlled elevator speed transport caps without scratching, cracking, or deforming the surface — critical for pre-printed or pre-induction-sealed caps.
Low Power Consumption: 0.2 kW — One of the most energy-efficient machines in a packaging line, adding minimal operating cost even across multiple shifts.
PLC Controlled Sorting Mechanism — The PLC manages sorting logic, elevator speed, and the delivery gate for consistent performance and easy integration with the capping machine's control signals.
Stainless Steel & Food-Grade Materials — Frame and cap-contact surfaces are stainless steel and food-grade, meeting hygiene requirements for food, beverage, cosmetic, and pharmaceutical environments.

The Automatic Cap Sorter & Elevator pairs with automatic capping machines across a broad range of industries:
Food & Beverage — Bottled water, juice, cooking oil, soy sauce, vinegar, condiment bottles, jam jars, honey jars
Cosmetics & Personal Care — Shampoo, conditioner, body lotion, face cream, liquid soap, shower gel, toner
Pharmaceutical — Medicine bottles, supplement containers, vitamin jars, syrup bottles — where consistent cap supply supports GMP compliance
Daily Chemicals — Household cleaner, laundry detergent, disinfectant, fabric softener on high-volume packaging lines
Industrial & Agricultural Chemicals — Lubricant bottles, agricultural liquid containers, surface treatment products
The cap sorter eliminates a dedicated operator at the capping station and ensures the capping machine never runs short of cap supply during continuous production.
Packaging Line Systems Experience — Yucheng designs and manufactures filling machines, capping machines, foil sealers, and labelers. The cap sorter is built as part of an integrated line, engineered to interface cleanly with our equipment and other major brands.
Minimal Operator Dependency — The 225-liter hopper and automated sorting run for extended periods between refills, freeing operators from hand-placing caps one by one.
Durable, Low-Maintenance Design — Simple elevator-and-sorter mechanics with PLC control mean fewer moving parts than vibratory bowl alternatives, resulting in lower maintenance frequency and easier troubleshooting.
OEM & Custom Configuration — Cap size range, elevator height, chute angle, and delivery gate design are all adjustable for your specific capping machine and line layout.
Full After-Sales Support — Our service team provides installation guidance, video commissioning, spare-parts supply, and remote troubleshooting worldwide.
Q: What types of caps does this machine sort?
A: The machine handles round screw caps, press-on caps, and flip-top caps from Φ40 mm to Φ100 mm. Caps must be round in cross-section for the orientation mechanism to function correctly. For non-round caps (square or oval), contact us to discuss custom sorting solutions.
Q: How does the machine know if a cap is correctly oriented?
A: The elevator track is configured so only caps sitting rim-down, top-up can pass through the delivery gate. Inverted or misoriented caps are deflected back into the hopper by the track geometry and re-enter the sorting cycle — no sensors required.
Q: Can the cap sorter be adjusted for different cap sizes?
A: Yes. The sorting track and guide components are adjustable or exchangeable for different diameters within the Φ40–100 mm range. For lines running multiple cap sizes, specify all sizes at order time so we can supply the appropriate change parts.
Q: How long can the machine run before the hopper needs refilling?
A: At 40–80 caps per minute and a 225-liter hopper, the machine runs 30 minutes to over an hour per load, depending on cap size (smaller caps pack more densely). The large hopper minimizes refill interruptions on continuous production shifts.
Q: Is this machine compatible with capping machines from other brands?
A: Yes. The cap sorter delivers caps via an adjustable chute to the capping machine's inlet. Chute height and angle match most standard automatic capping machine inlets. Share your capping machine model or inlet specifications and we will confirm compatibility.
Q: What is the lead time and MOQ?
A: MOQ is 1 unit. Standard machines are available within 7–12 business days. Customized configurations — non-standard elevator heights or special chute designs — require 15–20 business days.
Q: Can this machine be integrated into a complete filling, capping, and labeling line?
A: Absolutely. Yucheng manufactures filling machines, capping machines, foil sealers, and labelers. The cap sorter serves as the upstream cap supply module in these complete lines. We can design and supply the full packaging line, including conveyor layout and control integration.
Tell us your cap diameter, capping machine model, and line speed requirement, and our team will confirm compatibility and provide a competitive quotation.
