Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing magnetic frame opening devices for can bodies are prone to frame damage, are complex and expensive, and obstruct the view and access to the device, making adjustments difficult due to the placement of magnet boxes on the transport path.
Innovation Solution
A magnetic frame erecting device with controllable magnet arrangements under and above the infeed transport device, allowing frames to be held, lifted, and transported magnetically without side-mounted magnet boxes, enabling easier observation and adjustment of the frame's trajectory from lying to erected positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If magnet boxes are arranged on both sides of the conveying path, then the frames can be centered and held magnetically, but the risk of frame damage increases and the view into the device interior is blocked
Solution Approach 1:
The patent removes the side-mounted magnet boxes from the system and replaces them with a top-mounted magnetic field generation system. This extraction eliminates the harmful contact between side magnet boxes and frames while maintaining the essential magnetic holding and centering functions through a different spatial arrangement.
Solution Approach 2:
The patent transitions from a lateral magnetic field arrangement (side-mounted boxes) to a vertical magnetic field arrangement (top-mounted system). This dimensional change allows the magnetic field to act on frames from above without requiring side-mounted components that could contact and damage the frames.
2Reliability
If magnet boxes are arranged on both sides of the conveying path, then magnetic holding is achieved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The patent combines the functions of multiple side-mounted magnet boxes into a single top-mounted magnetic field generation system. This merging reduces the number of separate components, simplifies the overall structure, and lowers manufacturing costs while maintaining the necessary magnetic holding capability for frame centering and positioning.
3Manufacturing precision
If magnet boxes are arranged on both sides of the conveying path, then magnetic centering is achieved, but access to the device interior and trajectory observation become difficult
Solution Approach 1:
The patent removes the side-mounted magnet boxes that obstructed the view into the device interior. This extraction improves accessibility for maintenance and allows clear observation of the frame trajectory during the setting up process, while the top-mounted system maintains precise frame centering through vertical magnetic field application.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution eliminates the risk of frame damage, reduces manufacturing costs, and improves visibility and adjustability within the device, allowing for effective and efficient frame positioning without side-mounted magnet boxes, suitable for various frame dimensions and ratios.
Implementation Method 1
A first magnet arrangement, which can be activated and deactivated in a controllable manner by the controller, is arranged under the infeed transport device in such a way that a frame lying on the infeed transport device can be releasably held magnetically on the infeed transport device
Implementation Method 2
A second magnet arrangement is arranged above an area of the infeed transport device in which the frames are transported and is designed in such a way that a frame lying on the infeed transport device can be lifted by means of the magnetic field of the second magnet arrangement
Implementation Method 3
A third magnet arrangement is provided above the transport device and is designed and arranged in such a way that a raised frame can be further lifted and lifted off the infeed transport device and can be transported suspended magnetically on the transport device

AI summary
A magnetic can-body standing-up apparatus (Z) comprises an inlet transporting device (10) for conveying lying can bodies (4), a transporting device (12) arranged above the inlet transporting device (10) for conveying upright can bodies (9) hanging on the transporting device (12), and a controller (13). A first magnet arrangement (1) which is activatable and deactivatable in a manner controllable by the controller (13) is arranged below the inlet transporting device (10) in such a manner that a can body (4) lying on the inlet transporting device (10) is magnetically securable in a releasable manner on the inlet transporting device (10). A second magnet arrangement (2) is arranged above a region of the inlet transporting device (10) in which the can bodies are transported and is configured in such a manner that a can body (4) lying on the inlet transporting device (10) can be lifted up by means of the magnetic field of the second magnet arrangement (2) when the magnetic field of the first magnet arrangement (1) is deactivated. A third magnet arrangement (3) is provided above the transporting device (12) and is configured and arranged in such a manner that a can body (4a) which has been lifted up can be lifted up further and can be lifted off the inlet transporting device (10) and can be transported upright hanging magnetically on the transporting device (12). The controller (13) is configured in order to activate the first magnet arrangement (1) when a front edge of a can body (4) lying on the inlet transporting device (10) passes the second magnet arrangement (2) and in order to deactivate the first magnet arrangement (1) when a trailing edge of said can body (4) comes to lie under the second magnet arrangement (2).
