Inline Capping Machine
Inline Cappers
Inline Capping Machine is an automatic bottle capping system designed for continuous cap application and tightening on bottles moving through a linear conveyor. The machine is suitable for pharmaceutical, food, beverage, cosmetic, nutraceutical, chemical and other industrial packaging applications requiring consistent and automated bottle capping.
The Inline Bottle Capping Machine can be configured according to bottle dimensions, cap type, required production speed and capping torque. Automatic cap feeding, bottle handling, multiple capping heads and controlled torque systems can be incorporated according to the application.
The machine can be integrated with automatic bottle washing, liquid filling, powder filling, cap feeding, labelling, coding, inspection and secondary packaging equipment to create a complete automated bottle packaging line.
What Is an Inline Capping Machine?
An Inline Capping Machine is an automatic bottle capping system in which bottles move continuously along a straight conveyor path while caps are placed and tightened.
The machine performs the main capping operations automatically:
- Bottle infeed
- Cap feeding
- Cap placement
- Bottle positioning
- Cap tightening
- Torque control
- Capped bottle discharge
The linear arrangement allows the capping machine to be integrated into continuous packaging lines. Depending on the bottle and closure requirements, the machine can be configured with suitable capping heads, cap feeding systems, bottle guides and torque-control arrangements.
Working Principle
Bottle Infeed
Bottles enter the machine through the infeed conveyor after filling or other upstream processing. The conveyor maintains controlled bottle movement through the capping station.
Bottle Positioning
Bottle guides and sensors position the bottles correctly before cap placement and tightening. Suitable bottle handling arrangements can be incorporated according to the container shape and production speed.
Cap Feeding
Caps are supplied through an automatic cap feeder, cap elevator, cap chute or other suitable cap-handling arrangement.
Cap Placement
The cap is transferred and positioned on the bottle neck before the tightening operation. Cap placement is synchronized with bottle movement to maintain continuous operation.
Bottle Stabilization
Bottle gripping belts, side guides or other suitable bottle handling systems can be used to stabilize the container during capping.
Cap Tightening
The capping head engages with the cap and applies controlled tightening force or torque according to the closure requirements.
Torque Control
The capping system can be configured with adjustable torque control to provide consistent cap tightening and help maintain repeatable closure performance.
Capped Bottle Discharge
After capping, the completed bottles continue through the discharge conveyor toward labelling, coding, inspection or other downstream packaging equipment.
