Pivoting Edging Unit for Angled Workpiece Coating
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing machining centers are unable to effectively coat narrow sides of plate-shaped workpieces that run at an angle to the top or bottom, as they are not designed to accommodate non-flat or non-parallel surfaces.
Innovation Solution
The edging unit is pivotably mounted on a bearing section, allowing it to be swiveled and adjusted to approach angled narrow sides, with features such as a feed device, pressure elements, adhesive application, and radiation or heat emission devices to facilitate the coating process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the edging unit is fixed in a single position, then the structure is simple and stable, but it cannot coat narrow sides that run at an angle to the wide side of the workpiece
Solution Approach 1:
The edging unit is made dynamically adjustable through pivotal mounting on the bearing section. The edging unit can be swiveled about an axis parallel to the two spatial directions in which the workpiece and edging unit can be moved relative to one another during edging, allowing the edging tape to be approached and attached flat to the angled narrow side of the workpiece. This dynamic positioning capability enables the system to adapt to different narrow side orientations without requiring multiple fixed edging units.
Solution Approach 2:
The bearing section is designed with dual rotational capabilities: it can pivot about an axis perpendicular to the two spatial directions to approach radii in the narrow side of the workpiece, and the edging unit itself can pivot relative to the bearing section. This multi-functional bearing section allows a single edging unit to handle various workpiece geometries including flat narrow sides, angled narrow sides, and radii, replacing what would traditionally require multiple specialized units.
2Adaptability or versatility
If pressure rollers are used to adjust curvature or corrugation of the narrow side, then flat or parallel surfaces can be achieved, but this technique cannot be used to coat narrow sides that run at an angle to the wide side
Solution Approach 1:
The edging unit incorporates continuous pivoting capability relative to the bearing section, allowing it to be fixed in fixed or any angle settings. This dynamic angular adjustment enables the edging unit to maintain proper orientation and contact with narrow sides at different angles while still achieving flat and parallel coated surfaces through the combined action of pressure rollers and the angled positioning.

AI summary
The machining center has an edging unit (3) for feeding and applying an edge strip (2) to the narrow side (1a) of the work piece (1). The edging unit and the work piece are movable relative each other in two spatial directions parallel to a work piece plane. The edging unit is pivotally mounted on a bearing section (4) around an axis parallel to the two spatial directions.
