Lumber Stacking Assembly for Squared Layer Accumulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manufacturing facilities face challenges in creating evenly stacked and squared piles of objects, such as wood barrel staves, due to varying sizes and the difficulty in segregating and sorting items on conveyors for efficient handling and transport.
Innovation Solution
A system comprising a diverter, accumulator, and lift assembly that diverts, squares, and stacks objects on a conveyor system, using a diverter to move objects to a second path, an accumulator to hold objects until a selected amount is reached, and a lift assembly to transfer objects to a queuing area, ensuring objects are squared and stacked neatly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If objects of varying sizes are sorted and stacked manually or with simple conveyors, then the stacking process becomes complex and time-consuming, but automated systems with diverters and accumulators can create even, squared stacks efficiently
Solution Approach 1:
The stacking system is divided into distinct functional modules: a diverter mechanism that separates objects by size, an accumulator that temporarily holds sorted objects, and a stacker that builds even stacks. This segmentation allows each component to perform its specific function efficiently, resolving the contradiction by making the complex task manageable through modular design
Solution Approach 2:
The accumulator acts as an intermediary between the diverter and the stacker. It temporarily holds sorted objects and releases them in a controlled manner to the stacker, enabling the system to maintain high productivity while managing complexity through buffered intermediate storage
2Manufacturing precision
If a simple conveyor is used to transport objects, then the system is easy to operate, but it cannot create even, squared stacks for safe handling and transport
Solution Approach 1:
The diverter performs preliminary sorting of objects by size before they reach the stacker. By pre-separating objects into appropriate groups, the system achieves precise stack alignment without requiring complex real-time adjustments during the stacking operation itself
Solution Approach 2:
The accumulator automatically controls the timing and sequence of object release to the stacker based on received signals. This self-service capability allows the system to maintain precise alignment without requiring manual intervention or complex operational controls
3Stability of the object's composition
If objects are stacked without sorting by size, then the process is simple and fast, but the resulting stack is uneven and unsafe for handling and transport
Solution Approach 1:
The diverter segments the object stream by size, directing different size groups to appropriate accumulation zones. This segmentation creates stable stack compositions without requiring complete sorting of every object, balancing stability requirements with time efficiency
Solution Approach 2:
The accumulator maintains continuous operation by constantly receiving objects from the diverter and simultaneously supplying them to the stacker at a controlled rate. This continuous flow minimizes idle time while ensuring proper sorting, preventing loss of time without compromising stack stability

AI summary
An assembly and method thereof creates a stack of objects. The assembly has a diverter to move objects having a desired size from a first conveyor to a second conveyor. The diverter utilizes diversion plates. The second conveyor transfers the objects to an accumulator. The objects that are accumulated are squared and then moved to a raised position. A lift assembly then lifts the accumulated objects that were square and translates the objects to a queuing assembly. The process repeats itself to construct a stack of objects with multiple layers of objects. The created stack of objects may then be transferred to a subsequent destination for further use or processing.
