Book Stacking Device Tilting Deposit Arm
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing book stacking methods often result in damage to books due to the need to push them over one another during the stacking process.
Innovation Solution
A stacking device and method that tilts books onto a stacking table using a depositing arm, allowing them to be placed on top of each other without direct contact, reducing the likelihood of damage, and includes features like a height sensor and conveyor belt for efficient stacking and movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If books are pushed over one another during stacking, then the stacking process is simple and fast, but the books are easily damaged
Solution Approach 1:
A depositing arm is introduced as an intermediary component between the book feed mechanism and the stack. The depositing arm receives books standing on their side edge and tilts them onto the stack, avoiding direct pushing contact between books and reducing surface damage while maintaining efficient stacking operation
Solution Approach 2:
Instead of pushing books horizontally over the stack surface, the system inverts the approach by tilting books from a vertical standing position onto the stack. This reverse motion pattern places books edge-first onto the stack, minimizing contact with book surfaces and eliminating the harmful pushing action
2Object-affected harmful factors
If books are placed one by one with tilting movement, then book damage is reduced, but the stacking process becomes more complex
Solution Approach 1:
The depositing arm is divided into functionally independent segments: a book receiving portion that holds books standing on their side edge, and a tilting mechanism that rotates the book onto the stack. This segmentation allows each component to perform its specific function efficiently while keeping the overall mechanism manageable and maintainable
3Manufacturing precision
If stacking table height is adjusted for each book, then consistent stacking height is achieved, but the process time increases
Solution Approach 1:
The stacking table height is adjusted in advance before books are deposited onto it. By pre-positioning the table at the correct height, the system eliminates the need for time-consuming height adjustments during the stacking process, while still achieving consistent stack heights through the height sensor's feedback control
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 effectively minimizes book damage during stacking by avoiding direct contact and ensuring consistent stacking heights, enabling the efficient formation and transportation of book stacks.
Implementation Method 1
the height sensor has a light barrier which is arranged such that when the height of the top edge of the stack is not equal to the height of the top edge of the stacking table or the stack on which the object has been placed before this object has been placed, the photocell is broken
Implementation Method 2
the stacking table has a support surface for the stack, which is formed by a conveyor belt in order to move the stack out of the stacking device
