Cover Feeder with Dual Receiving Devices for Multi-Format Book Production
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional book finishing lines face inefficiencies in processing book covers of different formats, especially in small and very small runs, as they require individual placement on the cover feeder, which is uneconomical and lacks flexibility in order and format handling.
Innovation Solution
A cover feeder system with a second receiving device for stacks of book covers with different formats, a controller for format and sequence information, and a centering device for lateral adjustment, allowing for the processing of book covers in any order and format, enabling economical handling of small and very small orders.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If book covers of different formats are processed individually on the cover feeder, then each book cover can be properly centered and aligned, but the processing becomes uneconomical and time-consuming especially for small and very small runs
Solution Approach 1:
The cover feeder is divided into two separate receiving devices: a first receiving device for book covers of the same format and a second receiving device for book covers of different formats. This segmentation allows the system to handle different types of book covers through appropriate pathways, enabling batch processing of multi-format covers while maintaining individual centering precision when needed.
Solution Approach 2:
A controller acts as an intermediary that receives format information about book covers in the second receiving device and automatically adjusts the centering device settings. This intermediary coordination enables the system to process multiple formats without manual reconfiguration, maintaining precision while improving productivity through automated adaptation.
2Adaptability or versatility
If a single receiving device is used for all book covers, then the device structure remains simple, but it cannot economically handle book covers of different formats in any order
Solution Approach 1:
The receiving device is segmented into two functional units: a first receiving device optimized for same-format batches and a second receiving device for different-format stacks. This segmentation provides format handling flexibility while keeping each unit's structure relatively simple and specialized for its specific function.
Solution Approach 2:
The cover feeder system achieves multi-functionality by combining two receiving devices that can handle both same-format and different-format book covers. The system can process book covers in any order and format combination by routing them through the appropriate receiving device, making the overall system universal without requiring each component to be overly complex.
3Manufacturing precision
If book covers are placed individually on the cover feeder, then proper centering can be achieved, but extensive manual placement is required which reduces productivity
Solution Approach 1:
Book covers of different formats are pre-stacked in the second receiving device in the desired sequence before processing. This preliminary stacking eliminates the need for individual manual placement during production, significantly reducing placement time while the controller subsequently manages the centering process automatically.
Solution Approach 2:
The system uses a controller that automatically receives format information and adjusts centering settings without manual intervention. The book covers are fed through the system with automatic centering adjustments, eliminating manual placement and centering operations while maintaining accuracy.
4Productivity
If stacks of book covers with different formats are processed one after another, then format changes can be handled, but the system lacks flexibility to process covers in any order
Solution Approach 1:
The controller receives format information about book covers in the second receiving device and uses this feedback to automatically adjust centering settings and processing parameters. This feedback mechanism enables the system to adapt to different formats and sequences dynamically, providing order flexibility while maintaining batch processing efficiency.
Solution Approach 2:
The system transitions from static, fixed-format processing to dynamic, adaptive processing. The controller continuously adjusts centering and processing parameters based on the detected format and sequence of book covers, enabling flexible handling of any order while maintaining productivity through automated batch processing.

AI summary
The invention relates to a cover feeder (9, 9') for supplying book covers (5, 5') to a production unit (10') of a book finishing line (1). The cover feeder (9, 9') has a first receiving device (14) for book covers (5) of one format that can be placed individually, symmetrically and/or as a stack (15) and a second receiving device (18) arranged upstream of the first receiving device (14) for a stack (15') of book covers (5') of different formats.In addition, the cover feeder (9, 9') has a control unit (38) to which information on the format and order of the book covers (5') of the stack (15') of book covers (5') with different formats can be transmitted, and a centering device (20) connected to the control unit (38) for the corresponding defined lateral displacement and/or alignment of each of the book covers (5') withdrawn from the second receiving unit (18) and located on the first receiving unit (14).
