Section Bar Unloading Rack With Inclined Pockets to Prevent Scraping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing work centers for processing section bars made of aluminum, light alloys, or PVC face issues with large-sized assembly, low unloading productivity, and damage due to section bars scraping in horizontal pockets during storage.
Innovation Solution
The work center design includes a compact unloading unit with inclined pockets and a transfer assembly that moves section bars vertically to prevent scraping, ensuring high productivity and minimizing damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the store comprises racks with horizontal pockets for storing section bars, then the section bars can be stored in the store, but the section bars scrape along the pockets and are damaged
Solution Approach 1:
The invention changes the geometric parameter of the storage pockets from horizontal to inclined (with an inclination angle of 5-45 degrees relative to the horizontal plane). This parameter change prevents section bars from scraping along the pocket surfaces during storage, as the inclined orientation eliminates the sliding contact that causes damage while still allowing effective storage.
2Productivity
If the unloading unit has a simple transfer mechanism, then the device complexity is reduced, but the productivity becomes smaller than the processing station productivity
Solution Approach 1:
The invention implements a dynamic transfer mechanism where the transfer assembly can move between different positions (first position for loading, second position for unloading) and the pockets can be tilted between storage and transfer orientations. This dynamic capability allows the unloading unit to match the productivity of the processing station by enabling rapid transfer operations without requiring overly complex mechanisms.
3Area of stationary object
If the store and unloading unit are designed with traditional horizontal storage, then the structure is simple, but the assembly becomes relatively large-sized
Solution Approach 1:
The invention utilizes the vertical dimension by inclining the pockets at an angle rather than storing section bars horizontally. This dimensional change allows the storage system to achieve compact footprint while maintaining storage capacity, as the inclined arrangement optimizes space utilization in the vertical direction and reduces the horizontal space required for the same storage capacity.

AI summary
A work centre to process section bars (2) has a feeding device (17) to feed the section bars (2) through at least one processing station (16) and an unloading station (12) to retrieve the section bars (2) that were just processed from the feeding device (17) and store them in a store (47) having at least one rack (52), which is delimited by a substantially horizontal bottom wall (53) and is provided with a plurality of inclined pockets (54), each delimited by two side walls (55) parallel to one another and inclined at an angle other than 90° relative to the bottom wall (53).
