Stacking Shaft Mechanism for Folding Box Blanks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for stacking folding box blanks are limited in adaptability and complexity, particularly when handling small blanks that tend to tilt due to low mass and moment of inertia, requiring multiple drives and complex control systems to manage varying sizes and shapes.
Innovation Solution
A device with a single-axis drive for the lifting table, a two-axis drive for the clipboard, and a two-axis drive for the hold-down device, allowing for flexible control of paths and reducing equipment complexity by using only one clipboard, ensuring stable stacking and transport of small and large folding box blanks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If two temporary supports are used to support the forming stack, then the stacking process is stable, but the device complexity increases with multiple drives and control systems
Solution Approach 1:
The patent combines the functions of two separate temporary supports into a single temporary support device that can perform both supporting functions through different positional configurations. This reduces the number of drives and control systems while maintaining stacking stability.
Solution Approach 2:
The single temporary support device is designed with multi-functionality, capable of supporting the forming stack in different positions and configurations. The device can alternate between different support roles, eliminating the need for separate dedicated supports and reducing overall system complexity.
2Productivity
If small folding box blanks are stacked at high speed, then productivity increases, but the blanks jam and tip over due to low mass and moment of inertia
Solution Approach 1:
The patent applies preliminary anti-action by using the temporary support device to prevent the folding box blanks from tipping over before they can jam. The support device positions itself to counteract the tipping moment caused by high-speed stacking, maintaining stability despite the low mass and moment of inertia of small blanks.
Solution Approach 2:
The temporary support device performs preliminary action by establishing support positions in advance before the stacking operation begins. This ensures that when small folding box blanks enter the stacking space at high speed, the support structure is already in place to prevent jamming and tipping, maintaining both speed and reliability.
3Device complexity
If the device is designed with fixed movement sequences, then the control system is simple, but the adaptability to various folding box blanks is limited
Solution Approach 1:
The patent introduces dynamics to the control system by enabling the temporary support device to adjust its movement sequences based on the specific requirements of different folding box blanks. The control system can adapt the timing, position, and duration of support operations to match the characteristics of various blank sizes and shapes, maintaining simplicity while achieving high adaptability.
