Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing grouping devices for piece goods, such as beverage containers, are limited in their ability to handle high processing speeds and offer limited variability in format dimensions and control over divider elements, often requiring mechanical changes for motion control and using multiple chain systems.
Innovation Solution
A device with movable divider elements driven by gearless direct drives that rotate independently along a closed movement path, allowing for variable feed speeds and gap widths, and using magnetic or electromagnetic drives for precise control, enabling flexible adjustment and reduced number of divider elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional chain systems with mechanical dividers are used, then the device can handle basic grouping tasks, but the processing speed is limited and format adjustments require mechanical changes
Solution Approach 1:
The patent replaces traditional mechanical chain systems with magnetic fields generated by magnet arrays. The magnetic force field acts on ferromagnetic piece goods to control their movement, positioning and grouping without physical contact. This substitution enables high-speed processing (up to 600 pieces per minute) while allowing flexible format adjustments through electronic control of magnet positions and strengths, eliminating the need for mechanical reconfiguration.
Solution Approach 2:
The system uses dynamically adjustable magnetic field configurations where the strength, position and distribution of magnets can be changed in real-time based on the desired grouping format. This dynamic control allows the same device to handle multiple formats and configurations without mechanical changes, while maintaining high processing speeds through optimized magnetic field patterns.
2Adaptability or versatility
If multiple chain systems with numerous divider elements are used, then grouping coverage is comprehensive, but the device complexity increases
Solution Approach 1:
The patent merges the functions of multiple chain systems and divider elements into a single magnetic field-based system. Instead of using separate mechanical chains to control different groups of items, the system uses a unified array of magnets that can simultaneously control multiple piece goods across the entire conveyor width. This consolidation reduces device complexity while maintaining comprehensive grouping coverage through coordinated magnetic field control.
Solution Approach 2:
The magnetic field system serves multiple functions simultaneously: it attracts, positions, groups, and releases piece goods without requiring separate mechanical mechanisms for each function. The same magnet arrays that attract items can also position them in specific patterns and release them at designated locations, eliminating the need for multiple specialized mechanical subsystems.
3Ease of operation
If ferromagnetic piece goods are used with magnetic fields, then contactless control is achieved, but the application range is limited to magnetic materials
Solution Approach 1:
The system changes the magnetic parameters (field strength, gradient, distribution) to optimize control for different ferromagnetic materials and geometries. By adjusting these parameters, the system can effectively handle various magnetic materials including steel containers, cans, and other ferromagnetic piece goods with different properties, expanding material compatibility within the ferromagnetic category through parameter optimization rather than physical changes.

AI summary
The device (10) has a transport device (16) that transports articles (12,14) via a transport path (20). The transport device is moved transversely in the transport direction (TR) during the feed stream (18) of articles. The movable scheduler elements (24) are attached to lower bar (44) of classifier (25) and adjusted so as to adjust the formation of gaps (32) between successive articles. The feed rates of classifier along the transport trajectory (26) are varied depending on parameter relating to variable gap widths of articles. An independent claim is included for method for packaging articles.
