Cap Feeder with Inclined Chute for High-Speed Container Capping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cap application devices for containers lack efficiency and durability in applying threaded and push-on caps to containers, particularly in high-speed conveyor systems, as they often require complex mechanisms and frequent maintenance.
Innovation Solution
A cap feeding device with a movable feeder equipped with carriers that catch caps from an inclined chute or dispenser and position them above a conveyor, where grippers or cap holders can securely attach the caps to the containers, utilizing a combination of linear motors and support mechanisms for precise movement and alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a complex cap dispensing mechanism is used to supply caps to containers, then cap application can be achieved, but device complexity increases and maintenance frequency increases
Solution Approach 1:
The cap feeding system is divided into separate functional modules: a cap magazine for storage, a cap feeder with carriers for transport, and a cap holder for application. This segmentation allows each module to be optimized independently and simplifies maintenance by isolating wear-prone components.
Solution Approach 2:
The cap feeder uses gravity-fed caps from the magazine that automatically load onto carriers as they pass through the inclined chute. The system self-regulates cap flow without requiring additional actuators or complex control mechanisms, reducing both complexity and maintenance needs.
2Productivity
If a traditional cap feeder design is used, then cap supply is possible, but efficiency decreases due to mechanical stress and failures
Solution Approach 1:
The traditional mechanically-driven cap feeder is replaced with a gravity-based system where caps flow naturally down an inclined chute onto carriers. This eliminates complex drive mechanisms, reduces mechanical stress on components, and increases reliability while maintaining high throughput capability.
Solution Approach 2:
The cap feeder implements dynamic carrier movement where carriers are continuously fed and transferred in a smooth cyclic motion. This dynamic approach allows the system to handle high-speed conveyor operations without creating excessive mechanical stress on individual components.
3Manufacturing precision
If caps are caught from a horizontal dispenser, then cap transfer is possible, but manufacturing precision and cap placement consistency deteriorate
Solution Approach 1:
The cap dispenser chute is designed with an asymmetric inclined geometry that naturally guides caps into a consistent angular orientation as they exit. This asymmetric design ensures that caps are presented to carriers at a predetermined optimal angle, improving placement precision without requiring additional alignment mechanisms.
Solution Approach 2:
Caps are pre-oriented and pre-positioned in the inclined chute before being transferred to carriers. The chute geometry performs the alignment function in advance, so that when caps reach the carrier transfer point, they are already correctly positioned and oriented for consistent placement on containers.

AI summary
A method of applying a cap (12) to a neck (14) of a container (16) comprising the steps of retaining a cap (12) in a position inclined in relation to a horizontal plane and catching said cap while moving a cap feeder (24). Cap feeder (24) supporting said cap (12) is then moved to a position over containers (16) and said cap (12) is lifted. Said cap feeder (24) is moved away from the position over conveyor (26) to allow said cap (12) to be lowered to a position engaging said neck (14) of container (16). A drive mechanism (30) supports cap feeder (24) and is arranged to move cap feeder (24) between different positions where cap (12) caught and delivered, respectively.
