Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing timber stripping arrangements often result in disorderly removal of layers, particularly with thin timber, due to dimensional variations, leading to issues during transport and potential machine breakdowns.
Innovation Solution
A stripping transporter with flexible, elastomeric-covered endless mobile elements and a drive system allowing controlled rotation, combined with a suspension system that adapts to stack deviations, ensures orderly removal by maintaining board parallelism and preventing premature edge sliding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If gravity is used to strip layers of timber from the stack, then the stripping process is simple and energy-efficient, but the boards become disordered and non-parallel during transport
Solution Approach 1:
The patent introduces an inclined plane as an intermediary element between the stack and the horizontal transporter. This inclined plane with controlled surface (rollers or sliders) mediates the transition of boards from vertical stack to horizontal transport, ensuring they remain parallel throughout the process while still utilizing gravity for the stripping action.
Solution Approach 2:
The patent employs dynamically adjustable arms that can be displaced along the lift members. These arms form right angles with the lift members and can be positioned at different heights to adapt to variations in board dimensions and stack configuration, maintaining control over board alignment during the stripping process.
2Manufacturing precision
If the stripping transporter is locked against motion to retain the entire layer, then board order is maintained, but the stripping rate decreases
Solution Approach 1:
The patent implements periodic action by alternating between a stopping mode (where the stripping transporter is locked to retain the layer) and an active operating mode (where the layer is withdrawn). This cyclical operation allows controlled stripping of one layer at a time while maintaining board order, optimizing both precision and productivity.
3Reliability
If manual monitoring and stopping is used to prevent machine breakdown, then board damage is avoided, but productivity decreases due to manual intervention
Solution Approach 1:
The patent enables the system to monitor and correct stripping issues automatically without requiring manual intervention. The controlled surface and adjustable arms work together to self-regulate the stripping process, maintaining reliability while preserving productivity by eliminating the need to stop the machine for manual board placement.

AI summary
The invention relates to an arrangement for the stripping of layers of pieces of timber (3), in particular boards and planks, comprising a lift arrangement (1) that, inclined at an angle to the horizontal plane, supports a stack of timber (2), a transport element (17) that is located above the stack of timber and strips one layer at a time through interaction with the uppermost layer of timber in the stack of boards (2) perpendicular to the longitudinal direction of the boards, whereby the stripped layer of boards is delivered to a subsequent transporter (10). According to the invention, the endless mobile transport element (17) is placed in connection in a manner that transfers motion with a driving source with which the transport element can be transferred between a stopped position at which it is essentially locked against motion and an active operating position in which it is active, whereby the layer of timber is retained on the stack of timber (2) through interaction with the transport element when it is in its stopped position.
