Universal Sheet Feeder with Suction Gantry
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current sheet feeding machines require separate units for thick and thin sheets, leading to increased economic and space costs due to the need for two distinct production lines, as their operation mechanisms differ significantly.
Innovation Solution
A device that transforms a thick sheet feeding machine into a universal feeder by incorporating an insertion gantry, a feed carriage with sliding rails, an insertion head with pneumatically fed suction cups, and a base with a lifting mechanism, allowing for the alignment and feeding of sheets of any thickness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate machines are used for thick and thin sheets, then each machine can be optimized for its specific function, but the economic cost and space requirements increase significantly
Solution Approach 1:
The patent creates a universal sheet feeding machine that can handle both thick sheets (greater than 1 mm) and thin sheets (less than 1 mm) by integrating two feeding mechanisms: a bottom feeding system for thick sheets and a top feeding system with suction cups for thin sheets. This multi-functional design eliminates the need for separate machines, directly resolving the contradiction between optimization reliability and space requirements.
2Reliability
If separate machines are used for thick and thin sheets, then each machine can be optimized for its specific function, but the acquisition cost increases
Solution Approach 1:
The patent merges the bottom feeding mechanism (for thick sheets) and the top feeding mechanism with insertion gantry and suction cups (for thin sheets) into a single integrated machine. By combining these previously separate systems, the patent reduces acquisition costs while maintaining the optimized feeding functions for both sheet types.
3Adaptability or versatility
If a single machine handles both thick and thin sheets, then cost and space are reduced, but the device complexity increases
Solution Approach 1:
The patent employs dynamic switching between two feeding modes: bottom feeding for thick sheets and top feeding with suction cups for thin sheets. The insertion gantry and suction cup system can be deployed or retracted as needed, allowing the machine to adapt its complexity level based on the sheet type being processed, thereby managing overall system complexity while maintaining versatility.
4Manufacturing precision
If suction cups are used for thin sheets, then precise alignment and individual feeding are achieved, but the machine cannot handle thick sheets
Solution Approach 1:
The patent makes the suction cup system universal by combining it with a bottom feeding mechanism. The suction cups mounted on the insertion gantry provide precise alignment and individual feeding for thin sheets, while the bottom feeding mechanism handles thick sheets that cannot be suctioned, thus achieving both precision and versatility across different sheet thicknesses.

AI summary
A device for feeding sheet products into a thick sheet feeding machine including an insertion gantry, a feed carriage sliding on rails. The device includes an insertion head configured as a gantry. The insertion head includes a crosspiece and support legs positioned on the rails and a system of suction cups located in the crosspiece through a forward movement mechanism allowing the system to move. The device includes an insertion module moving vertically on guides of the insertion gantry, a base for placing the sheets, and an alignment control device for aligning the sheets with respect to the insertion module. The sheets are suctioned by the suction cups, which are moved by the forward movement mechanism in the direction of the insertion gantry.
