Cam-Guided End Flap Tucking for Precise Carrier Engagement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems face challenges in efficiently engaging and tucking end flaps of carriers during the packaging process, particularly in ensuring precise and controlled movement to avoid incidental contact with carrier surfaces.
Innovation Solution
A system utilizing a drive apparatus and cam track mechanism to move a tucking apparatus vertically and horizontally, with cam followers engaging with cam tracks to control the movement of tucking fingers, allowing precise engagement and tucking of end flaps into carrier recesses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple tucking mechanism is used, then device complexity is reduced, but manufacturing precision and control precision deteriorate
Solution Approach 1:
The tucking mechanism is divided into multiple independent tucking fingers (first tucking finger, second tucking finger, third tucking finger, fourth tucking finger) that can move independently. Each finger is controlled by separate cam followers and cam tracks, allowing precise individual control of each finger's vertical and horizontal movement to engage end flaps accurately without requiring a complex unified mechanism.
Solution Approach 2:
The mechanism employs dynamic cam followers that convert rotational motion into controlled vertical and horizontal movements of the tucking fingers. The cam tracks are designed with specific geometric profiles that dynamically adjust the position and orientation of each finger during the tucking operation, enabling precise engagement adaptability.
2Manufacturing precision
If multiple tucking fingers are used to engage end flaps, then manufacturing precision is improved, but device complexity increases
Solution Approach 1:
Multiple tucking fingers share common structural elements including the drive apparatus, cam track assembly, and support structure. The cam track assembly serves multiple functions by providing guided paths for multiple cam followers simultaneously. This multi-functionality reduces overall device complexity while maintaining the ability to precisely control multiple fingers for engaging different end flaps.
Solution Approach 2:
The cam followers are positioned within the cam track assembly, with each cam follower nested in its respective cam track. The tucking fingers are arranged in a compact configuration where smaller fingers can be positioned within or adjacent to larger ones, creating a space-efficient nested arrangement that reduces the overall footprint and complexity of the multi-finger system.
3Adaptability or versatility
If vertical and horizontal movement is implemented for tucking fingers, then adaptability to various carrier configurations is improved, but device complexity increases
Solution Approach 1:
The movement control is segmented into independent vertical and horizontal components for each tucking finger. Vertical movement is controlled by cam followers engaging with cam tracks that have vertical displacement profiles, while horizontal movement is controlled by separate mechanisms. This segmentation allows each component to be optimized independently, reducing overall complexity while achieving versatile multi-directional control.

AI summary
A method of engaging at least one end flap of a carrier includes moving the carrier below an end flap engagement assembly along a product path, activating a drive apparatus to cause an end flap tucking apparatus to move in a machine direction, engaging a first cam follower of the end flap tucking apparatus with a first cam track to cause vertical movement of at least one tucking finger of the end flap tucking apparatus relative to the carrier, engaging a second cam follower of the end flap tucking apparatus with a second cam track to cause movement of the at least one tucking finger of the end flap tucking apparatus along the machine direction relative to the remainder of the end flap tucking apparatus, and contacting and moving at least one end flap of the carrier with the at least one tucking finger of the end flap tucking apparatus.
