Conical Roller Separation of Sawn Timber Packages Without Jamming
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing apparatuses for separating sawn timber packages into main and side products often jam, leading to interruptions in transport and processing, and require manual labor for release, with additional bearing and transport means needed for separated boards.
Innovation Solution
The apparatus employs rotatably mounted conical rollers with acute-angled surfaces to engage in the sawing gap between main and side products, deflecting the side products away while minimizing jamming and reducing the need for additional bearing elements, using adjustable mounting and drives for optimal separation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a wedge is used as separating means, then the side product is deflected away from the main product, but the sawn timber package often jams with the wedge causing transport interruptions
Solution Approach 1:
The patent replaces the conventional wedge-shaped separating means with conical rollers. The conical shape with curved surfaces allows the rollers to penetrate the sawing gap and deflect side products through rolling motion rather than sliding contact. This curvature eliminates the jamming problem inherent in wedge designs while maintaining effective separation functionality.
Solution Approach 2:
The conical rollers are designed to rotate during operation, transforming the static wedge into a dynamic separating mechanism. The rotational capability allows the rollers to maintain continuous contact with the timber package during feed motion, enabling the timber to roll on the rollers without jamming while still achieving reliable side product deflection.
2Ease of operation
If additional bearing means and transport means are provided, then separated boards can be transported further, but the device complexity increases
Solution Approach 1:
The conical rollers serve multiple functions simultaneously: they act as the separating means to deflect side products, serve as bearing elements to support the main product during transport, and function as transport means through their rotational capability. This multi-functionality eliminates the need for separate bearing means and transport means, reducing device complexity while maintaining ease of operation.
Solution Approach 2:
The patent merges the functions of separating means, bearing means, and transport means into a single integrated conical roller system. By combining these previously separate components into one multifunctional element, the overall device complexity is reduced while preserving all necessary operational capabilities.
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 ensures reliable, high-productivity separation of sawn timber packages by minimizing jamming and centering the products, allowing for efficient transport of both main and side products without manual intervention.
Implementation Method 1
the roller penetrates with a circumferential separating edge into a vertically extending sawing gap of the sawn timber package. As a result, the boards of the sawn timber package are deflected away laterally with respect to the conveying direction
Implementation Method 2
At least two rotatably mounted conical rollers are provided as the separating means, which conical rollers each have a circumferential separating edge which is formed by two surfaces of revolution enclosing an acute angle. The two conical rollers are arranged on both sides of the sawn timber package and are oriented in such a way that they engage laterally in the horizontally extending sawing gap with their respective separating edges and roll on the main product with their first surface of revolution

AI summary
An apparatus for separating a sawn timber package cut from a log into main and side products during longitudinal transport thereof, having at least one separating device positioned such that, during a feed motion of the sawn timber package, it engages in a sawing gap between single- or multi-cut main product and side product and deflects the side product in a direction leading away from the main product. Two rotatably mounted conical rollers form the separating device, each having a circumferential separating edge formed by two surfaces of revolution enclosing an acute angle, and the two conical rollers are arranged on both sides of the sawn timber package and oriented such that they engage laterally into the sawing gap with respective separating edges and roll on the main product with their first surface of revolution, while deflecting the side product from the main product with their second surface of revolution.
