Automatic-Adjustable Stacker for Cardboard Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the die-cut/crease and printing industries, pre-treated cardboard items often suffer damage during transfer due to turbulence and contact with other cards or surfaces, leading to issues like ripping, wrinkling, and jamming, which disrupts production and requires manual adjustments for different job requirements.
Innovation Solution
An automatic-adjustable stacker system that grips and releases pre-treated cardboard items with minimal contact, using a controller to adjust parameters like length, width, and speed, ensuring controlled movement and placement to prevent damage, and can automatically sort and stack cardboards based on various criteria.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If manual handling and transfer of pre-treated cardboard items is performed, then flexibility in handling different job requirements is maintained, but cardboard damage occurs due to turbulence and contact with other cards or surfaces
Solution Approach 1:
A controlled transfer mechanism acts as an intermediary between cardboard sources and destinations, managing the transfer process to minimize turbulence and contact damage. The mechanism includes guided pathways and controlled release points that prevent cardboard items from contacting other cards or surfaces during transfer.
Solution Approach 2:
The patent replaces manual mechanical handling with an automated control system that uses sensors and actuators to manage cardboard transfer. This substitution eliminates human-induced turbulence and contact while maintaining precise control over the transfer process.
2Productivity
If manual adjustments are made for different job requirements, then adaptability to various parameters is achieved, but production efficiency decreases due to disruption and manual intervention
Solution Approach 1:
The system incorporates dynamically adjustable parameters including transfer speed, gripper force, and pathway configuration that can be modified in real-time based on job requirements. This dynamic adaptability allows continuous operation without manual intervention while handling different cardboard types and specifications.
Solution Approach 2:
Sensors monitor cardboard parameters and transfer conditions, providing feedback to the control system which automatically adjusts operational parameters. This closed-loop control enables the system to adapt to different job requirements while maintaining optimal performance and preventing damage.
3Reliability
If conventional transfer methods are used, then system complexity is minimized, but cardboard items suffer from ripping, wrinkling, and jamming
Solution Approach 1:
The transfer system is divided into discrete functional segments including individual grippers, separate transfer pathways, and independent control zones. This segmentation allows each component to be optimized for its specific function while reducing overall system complexity through modular design.
Solution Approach 2:
The system changes physical parameters such as transfer speed, gripper engagement force, and pathway geometry based on detected cardboard characteristics. These parameter adjustments optimize transfer reliability for different cardboard types without requiring complex mechanical redesigns.

AI summary
An automatic-adjustable stacker for controlling the movement of a media, such as cardboard, through a media handling system. The stacker includes a media receiver positioned proximate a feed of the media that receives a leading edge of the media and a controller that causes the media receiver to move from a first position for receiving the media, to a second position for depositing of the media at a desired location. The media receiver is configured to prevent the media from coming into contact with other media already located at the desired location until the media has arrived at the desired location, while creating a concave-like shape to the media while conveying it.
