Integrated Spindle Transfer for Painted Article Decoration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current production processes for articles with surface painting and graphic patterns require separate and complex logistical steps, leading to increased costs, damage risks, and compromised aesthetic features due to incompatible paint properties and mechanical stresses.
Innovation Solution
An integrated apparatus and method that allows for the simultaneous or sequential application of surface treatments, including painting and graphic patterns, using a modular system with spindles and transfer assemblies that maintain article integrity and adaptability, enabling efficient transfer and application without contact, and incorporating laser engraving for detailed graphics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If articles are transferred to a different production site for graphic pattern application, then graphic patterns can be applied to painted articles, but logistical complications increase and production costs rise
Solution Approach 1:
The patent combines the painting operation and graphic pattern application into a single integrated production line. The painting robot applies lacquer or paint to articles, and immediately afterward, a printing robot applies graphic patterns without requiring article transfer to a different production site. This merging eliminates logistical complications while maintaining the capability to produce painted articles with graphic patterns.
2Adaptability or versatility
If articles are repeatedly transferred between production sites, then graphic patterns can be applied, but the possibility of damage and processing defects increases
Solution Approach 1:
By integrating painting and printing operations in one production line, the patent eliminates repeated article transfers between production sites. Articles remain on the same conveyor system, moving directly from the painting robot to the printing robot, thereby preventing damage and processing defects that would result from multiple handling and transfer operations.
Solution Approach 2:
The patent establishes a continuous production flow where articles move without interruption from painting to printing operations. The integrated system maintains continuous article processing on a single conveyor, eliminating the breaks and transfers that would compromise article integrity while still enabling graphic pattern application on painted surfaces.
3Adaptability or versatility
If graphic patterns are applied after painting, then additional decorative elements can be added, but the patterns are exposed to mechanical friction and atmospheric agents that impair aesthetic features
Solution Approach 1:
The patent applies a protective clear coat over the graphic patterns after printing but before the articles leave the production line. This preliminary protective action shields the graphic patterns from subsequent mechanical friction and atmospheric agents during storage and distribution, preserving their aesthetic features while maintaining the versatility of applying patterns after painting.
4Ease of manufacture
If paints with specific optical and tactile features are used, then aesthetic needs are met, but adhesion of subsequently printed graphic patterns is compromised
Solution Approach 1:
The patent modifies the surface parameters of the painted articles by applying a primer or surface treatment layer between painting and printing operations. This intermediate layer changes the surface properties to provide adequate adhesion for graphic patterns while preserving the optical and tactile features of the underlying paint finish, thus resolving the conflict between aesthetic quality and pattern adhesion.
Applied Scientific Principles

AI summary
A plurality of workpiece-holding spindles (4) is arranged, each engaging an article (6) being processed, and a plurality of trays (10), each removably engaging a plurality of said spindles (4). The trays (10) are moved along a feeding line (2) extending along a feeding path (P) passing near a decoration module (13). By a transfer assembly (15), the spindles (4) carrying the articles (6) are transferred from the trays (10) on the feeding path (P), to the decoration module (13). A decorative treatment is applied to the articles (6) carried by the spindles (4), in correspondence with at least one treatment unit (40, 41, 42) operating along the decoration module (13). In correspondence with a painting module (14) operatively connected with the feeding line (2), the articles (6) carried by the spindles (4) are painted.
