Folding Machine Transport Device for Signature Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing combination folding machines face issues with inefficient delivery and onward transport of folded signatures, as the direction of signature layout or forwarding is determined by machine configuration, leading to space limitations and the need for frequent unit reconfiguration.
Innovation Solution
A folding machine with at least two knife folding stations and a receiving device for a buckle plate holder, which can be replaced by a transport device, allowing for improved signature layout and forwarding without passing through subsequent units, using a transport device with a curved switch, guide surfaces, and a blown air element for secure and efficient transport.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If signatures are transported through subsequent knife folding units for delivery, then the machine configuration determines the delivery direction, but this leads to space limitations and requires frequent reconfiguration of delivery or further processing units
Solution Approach 1:
The invention introduces a movable delivery unit that can be positioned at different locations along the machine axis depending on the fold pattern produced. This dynamic repositioning capability allows the delivery unit to adapt to different signature layouts without requiring complete machine reconfiguration, thereby improving delivery direction flexibility while reducing operational complexity
Solution Approach 2:
The delivery function is segmented from the fixed machine structure and implemented as a separate, movable delivery unit. This modular approach allows the delivery unit to be independently positioned and reconfigured based on production requirements, enabling flexible adaptation to different fold patterns and space constraints without affecting the core folding mechanism
2Productivity
If a fixed machine configuration is used to determine signature layout direction, then the folding process is simplified, but space limitations arise and delivery units must be frequently reconfigured
Solution Approach 1:
The movable delivery unit provides dynamic adaptability to different spatial requirements while maintaining consistent folding processing. The unit can be repositioned along the machine axis to accommodate different fold patterns and bookbindery space constraints, thereby improving versatility without compromising processing efficiency
Solution Approach 2:
The movable delivery unit serves multiple functions: it can deliver signatures in different directions, accommodate various fold patterns, and adapt to different space constraints within the bookbindery. This multi-functional design allows a single machine configuration to handle diverse production requirements, improving both productivity and adaptability

AI summary
The machine has knife fold station (1,4) and acceptance apparatus (6) accepts fold pocket portion (3), and produces signature from sheet-like portion (B1,Br) in which drawing-out is possible that inserts on acceptance plane to the acceptance apparatus. A conveying apparatus (5) for paper-ejecting signature is maintained by the acceptance apparatus.
