Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing book production systems face challenges with high dead times and manpower requirements due to the coupling of book block forming stations and cover binding machines, leading to inefficiencies and increased costs, especially in on-demand book production.
Innovation Solution
A system utilizing spiral towers with conveyor belts and electronic control units for temporary storage and movement between loading and unloading areas, allowing decoupled operation of book block forming stations and cover binding machines, optimizing the arrangement and delivery of book blocks based on size and time of formation, and ensuring flexible production with minimal downtime.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If book block forming stations and cover binding machines are coupled to operate in synchronism, then the system can maintain coordinated production flow, but the functional speed is limited to the slowest component and stopping one component causes the entire plant to stop
Solution Approach 1:
The patent divides the production system into independent segments: book block forming stations and cover binding machines operate separately with their own accumulation buffers. This segmentation allows each component to operate at its optimal speed without being constrained by the slowest component in the chain, thereby resolving the contradiction between coordinated flow and functional speed.
Solution Approach 2:
Accumulation buffers are introduced as intermediary elements between the book block forming stations and cover binding machines. These buffers decouple the synchronous operation requirement, allowing forming stations to produce book blocks continuously while binding machines process covers at their own pace, eliminating the bottleneck effect and preventing plant-wide stops.
2Reliability
If buffer transport is provided between book block forming stations and perfect binders, then stops or delays can be attenuated, but the plant can continue to operate only for limited periods of time
Solution Approach 1:
The patent transitions from a linear, single-dimension buffer transport to a multi-dimensional system with multiple accumulation buffers arranged in parallel and interconnected pathways. This dimensional expansion allows the system to maintain operational continuity for extended periods by routing book blocks through alternative buffer paths when one buffer is full or when binding machines require maintenance, thereby resolving the contradiction between stop attenuation and operational continuity.
3Ease of manufacture
If book blocks are sequentially collected on pallets and extracted manually, then the operations can be performed with simple equipment, but a lot of manpower is required
Solution Approach 1:
The patent implements automated extraction systems that enable the book block accumulation and transport system to serve itself. Book blocks are automatically transferred from accumulation buffers to binding machines through robotic extraction mechanisms, eliminating the need for manual labor while maintaining equipment simplicity. The system self-regulates the flow of book blocks based on binding machine readiness, resolving the contradiction between equipment simplicity and manpower requirements.
4Ease of operation
If expensive robots are used for automated book block extraction from pallets, then manpower requirements are reduced, but the cost of the system increases significantly
Solution Approach 1:
The patent employs cost-effective, simpler automated extraction mechanisms rather than expensive industrial robots. The accumulation buffers are designed as temporary storage solutions that can be easily replaced or reconfigured, and the extraction systems use basic mechanical conveyors and transfer mechanisms that are inexpensive and maintainable. This approach reduces manpower requirements while avoiding the high costs associated with sophisticated robotic systems.

AI summary
A production plant for books printed with digital technologies. comprising one or more forming stations of book blocks, one or more cover binding machines for assembling the book blocks with respective covers, an electronic center and a plurality of spiral towers for accommodating the book blocks of the forming stations and transfer them to the binding machines. The book blocks and the covers have respective book codes and cover codes uniquely associated with the respective books of a given working order. Each tower includes a conveyor belt that can be moved along a spiral path. a belt motorization group and an electronic control unit. The towers serve as a temporary storage for the blocks and capacity of movement between loading areas adjacent to the forming station and unloading areas adjacent to the binding machines. The electronic control units pre-set the towers to store in an optimized way along the conveyor belt the book blocks from the forming stations. to supply the binding machines with the stored book blocks and to form and memorize databases identifying the stored book blocks. The electronic center of the plant is interfaced with the electronic control units of the towers and with the binding machines for a survey of the loading data and for a functional coupling of the loaded towers with the binding machines.
