Venetian Blind Slat Stacking Unit Automation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The manual process of attaching slats to ladders in Venetian blind production is labor-intensive, time-consuming, and requires dedicated space, necessitating a more efficient and automated method for attaching ladders to slats.
Innovation Solution
A stacking unit with a sliding lane and positioning device for slats, along with local movement and control means, automatically positions and translates slats to engage coupling means with crossbeams, enabling automated attachment of ladders to slats with various coupling types, such as snap-inserts or tongues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual attachment of ladders to slats is used, then labor flexibility is maintained, but productivity is low and production time is excessive
Solution Approach 1:
The slat automatically engages with the ladder crossbeam through its own coupling means (tongues or snap-inserts) when the stacking unit moves, eliminating the need for manual attachment operations. The system uses the inherent coupling mechanisms on the slats to achieve self-attachment during the stacking process.
Solution Approach 2:
The coupling means (tongues or snap-inserts) are pre-positioned on the slats in a raised or open state during slat insertion. The attachment action is prepared in advance but not executed manually; instead, it occurs automatically when the stacking unit moves and the slat engages with the ladder structure.
2Productivity
If manual processing is used for ladder attachment, then equipment complexity is low, but production efficiency is poor and dedicated space is required
Solution Approach 1:
The stacking unit performs multiple functions: it inserts slats into the ladder structure, positions them correctly, and automatically attaches them through movement. This multi-functional design eliminates the need for separate attachment equipment and dedicated processing spaces, improving efficiency without proportionally increasing complexity.
Solution Approach 2:
The attachment function is merged with the stacking and positioning functions. The same stacking unit that inserts and positions slats also performs the attachment operation through controlled movement, combining multiple operations into a single integrated system.
3Productivity
If automated attachment is implemented, then productivity increases, but the attachment mechanism complexity increases
Solution Approach 1:
The attachment mechanism relies on the self-engaging coupling means already present on the slats (tongues or snap-inserts). The automation is achieved not by adding complex attachment mechanisms, but by using the slat's own coupling features to perform the attachment automatically during stacking movement.
Solution Approach 2:
The coupling means (tongues or snap-inserts) act as intermediaries between the slat and the ladder crossbeam. These pre-existing coupling elements mediate the attachment process, allowing automated engagement without requiring complex direct connection mechanisms.

AI summary
The invention relates to a stacking unit of slats on a support ladder provided with double crossbeams for the production of Venetian blinds. The unit comprises: - a sliding lane C which extends along a longitudinal extension axis X on an insertion plane m and along which a slat L is made to slide; - a device for positioning a ladder S on a positioning plane p orthogonal to the insertion plane m of the slat and transversal to the longitudinal axis X and to the sliding lane C. The unit 1 comprises means 10 for locally moving a slat L along a longitudinal axis X next to the positioning plane p of the ladder, once the slat has been inserted in a pair of crossbeams of the ladder. The present invention also relates to an attachment method of a slat to a ladder for the production of Venetian blinds.
