Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing transfer devices for packaging containers, such as tubes, face challenges in controlling and gripping containers during high-speed transfers from intermittent to continuous conveyor systems, leading to inefficiencies and reduced flexibility in production lines.
Innovation Solution
A method and device utilizing a pivoting frame with container pickers/placers that rotate about multiple axes to synchronize the speed and orientation of containers, ensuring continuous grip and precise placement from an intermittently operating filling line to a continuously operating cartoning machine, using a combination of pivoting, rotating, and accelerating movements to compensate for differences in height and spacing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If gravity-based transfer devices (drop-flap or rotating drum) are used to transfer packaging containers from intermittent to continuous conveyor, then the transfer can be performed with simple structure, but control of the packaging container during transfer phase is insufficient and friction remains uncertain
Solution Approach 1:
A transfer device acts as an intermediary mechanism between the intermittent conveyor and continuous conveyor. The transfer device includes a pivoting frame with container pickers that mechanically grip containers during transfer, providing reliable control while bridging the two conveyor systems with different operating modes.
Solution Approach 2:
The patent replaces gravity-based passive transfer mechanisms with an active mechanical gripping system. The container pickers use mechanical contact and friction control to securely hold containers during transfer, eliminating reliance on gravity alone and providing positive grip throughout the transfer phase.
2Productivity
If existing transfer devices are used to maintain continuous operation, then productivity can be improved, but the delivery conveyor must be located in a particular position relative to the transfer conveyor, reducing installation flexibility
Solution Approach 1:
The transfer device employs dynamic adjustment capabilities including variable pivoting angles of the frame and adjustable positioning of container pickers. This allows the device to adapt to different conveyor positions and configurations while maintaining high-speed transfer operation, eliminating fixed positional requirements.
Solution Approach 2:
The transfer device is segmented into independent adjustable components including the pivoting frame, individually positionable container pickers, and separate acceleration mechanisms. This modular segmentation enables flexible installation configurations while maintaining synchronized transfer at high production speeds.
3Productivity
If high production capacity is pursued with higher speeds, then productivity increases, but control and gripping of packaging containers during transfer phase becomes insufficient
Solution Approach 1:
The container pickers maintain continuous contact and gripping action throughout the entire transfer phase, from pickup to release. The mechanical grip remains active and controlled at all times during transfer, ensuring reliable container control even at high transfer speeds without interruption or loss of grip.
Solution Approach 2:
The device dynamically adjusts transfer parameters including pivoting speed, acceleration rate, and picker positioning to match high production speeds. The system modifies operational parameters in real-time to maintain optimal gripping force and control precision while operating at maximum productivity levels.

AI summary
The invention relates to a method for synchronizing, and a transfer device for synchronizing, a movement pattern between two units in a packaging line, wherein one unit is intermittently operated and the second unit is continuously operated. The invention is particularly intended for a transfer device between an intermittently operated filler unit and a continuously operated cartoning machine. The transfer device is provided with a frame (13) arranged to support tube pickers-/placers (28) and is arranged to perform a simultaneous pivoting movement about a first and a second shaft (16, 31), and for rotation about a third shaft (48) at right angles to the second shaft (31 ). The frame is further provided with means for adjusting the spacing between the tubes and means for compensating for differences in vertical position during the rotating movement in the case where the containers picked from the part circular conveyor of the filling unit.
