Crate Production Plant Using Pre-Attached Corner Posts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing packaging solutions for rigid crates, particularly those used for foodstuffs and fruits/vegetables, face challenges such as lengthy and complicated production processes, exposure of metal wire to humidity leading to rust and hygiene issues, and inefficiencies in material usage and resistance to compression and humidity.
Innovation Solution
A plant and method for producing crates from a single panel with pre-fixed corner posts, using milling machines for precise cuts and a stapling machine to attach posts, ensuring the metal wire is not in contact with the contents and allowing for automatic, efficient, and hygienic production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional crate production uses multiple stages with manual intervention, then the crate structure is robust, but the production process becomes long and complicated
Solution Approach 1:
The production process is divided into distinct functional modules: panel preparation unit, corner post attachment unit, and crate assembly unit. Each module performs a specific operation independently, allowing parallel processing and reducing overall production time while maintaining structural integrity.
Solution Approach 2:
Corner posts are pre-attached to panels in the corner post attachment unit before final crate assembly. This preliminary action simplifies the final assembly process and enables automated production, reducing both production time and operational complexity.
2Reliability
If metal wire is used for stapling inside the crate, then the structure is secure, but the metal wire becomes rusty when exposed to humidity
Solution Approach 1:
The stapling operation is extracted from the interior crate space and performed on the exterior surface of panels. Corner posts are attached to the outside of panels, preventing metal wire exposure to humid interior environments while maintaining secure structural connections.
Solution Approach 2:
The panel acts as an intermediary between the corner post and the crate interior. The metal wire staples the corner post to the panel's exterior surface, creating a barrier that protects the metal from humidity while ensuring structural strength through the panel's rigidity.
3Loss of substance
If a single panel is used to build up packaging in volume, then material waste is reduced, but the material must resist compression and humidity
Solution Approach 1:
The crate is constructed as a composite structure combining a rigid panel with attached corner posts. This composite design maintains structural integrity under compression and humidity exposure while utilizing the single panel efficiently, minimizing material waste through optimized geometry.

AI summary
Plant for production of crate-type packaging (200), starting from a panel (1) comprising a sheet (2) of rigid, non-flexible material and a film (20) applied to the sheet (2). The plant comprises a shearing machine (A), a first milling machine (B), a second milling machine (C), and a stapling machine (E) used to staple corner posts (6; 106), in the form of a rigid column, to parts of the panel intended to form transverse sides (5) and/or longitudinal sides (4) of the crate and related packaging.
