Rotatable Flexible Tabs for Carrier Packer Centering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional carrier packers experience downtime due to finger assemblies catching against the upper edges of partitions, leading to inefficiencies in loading cycles and increased idle time.
Innovation Solution
The implementation of rotatable flexible tabs aligned along shafts on opposite sides of the loading station, which can be lowered to guide bottles into carrier cells and raised to avoid interference once the bottles are placed, allowing for smooth conveyor operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional finger assemblies are used to guide bottles into carrier cells, then bottles can be directed into particular locations, but the fingers will catch against the upper edges of partitions causing production line stoppages
Solution Approach 1:
The patent applies the dynamics principle by making the centering fingers movable rather than fixed. The fingers are mounted on rails that allow them to move horizontally, enabling them to adapt to different bottle positions and avoid catching on partition edges. This dynamic adjustment capability resolves the contradiction by maintaining reliable bottle guidance while preventing the jamming that would stop production.
Solution Approach 2:
The patent changes the positional parameter of the centering fingers by allowing them to move along horizontal rails. This parameter change enables the fingers to maintain optimal positioning during the bottle insertion process, avoiding contact with partition upper edges while still effectively guiding bottles into cells. The movable design transforms the fixed parameter into a variable one, resolving the reliability-productivity contradiction.
2Manufacturing precision
If flexible members are provided to direct bottles into particular locations, then bottle positioning is improved, but the fingers interfere with bottle necks after bottles are located in cells
Solution Approach 1:
The patent uses dynamic movement of the centering fingers along horizontal rails to resolve the interference issue. After bottles are positioned in cells, the fingers can move horizontally to clear the path for conveyor operation and avoid interfering with bottle necks. This maintains positioning accuracy during insertion while ensuring smooth subsequent conveyor operation.
Solution Approach 2:
The patent applies preliminary action by having the centering fingers perform their guiding function during the bottle insertion phase, then moving to a retracted position before the conveyor operates. This temporal separation ensures that the fingers accomplish their positioning task before potentially interfering with bottle necks, allowing smooth conveyor operation to proceed without obstruction.
3Device complexity
If centering devices are made simple in construction, then device complexity is reduced, but reliability may be compromised
Solution Approach 1:
The patent applies segmentation by dividing the centering device into multiple independent finger elements that move on separate rails. Each finger operates independently, so if one encounters an issue, others continue functioning. This segmented design maintains simplicity while improving reliability through redundancy and localized problem isolation.
Solution Approach 2:
The patent changes the positional parameters of multiple simple finger elements along horizontal rails, creating a reliable system through coordinated movement. Rather than using a single complex mechanism, multiple simple movable elements work together to ensure reliable bottle centering, resolving the contradiction between simplicity and reliability.

AI summary
In a carrier packer, a centering device has two series of flexible tabs (23, 24), aligned along two parallel shafts (25, 26). The shafts rotate the flaps in two alternative angular positions. In a lowered angular position, the tabs are introduced partly in the cells (16, 17) of a carrier (12), to guide bottles towards the center of the cells. In an angularly raised position, the tabs are rotated away so as not to interfere with the bottle necks once the bottles have been fitted in the cells, so that a conveyor may take the carrier away.
