Modular Stapling Head with Exchangeable Driving Tool
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stapling devices for printed products are limited to either conventional U-shaped staples or eye-staples, requiring separate systems and labor-intensive head exchanges, making them inflexible and inefficient for handling different types of staples.
Innovation Solution
A modular stapling head design with a replaceable driving tool and retainer allows for quick switching between different staple types, using pre-shaped staples and adaptive driver modules for various staple designs, enabling flexible and efficient stapling operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a stapling device is designed for a single type of staple (either conventional U-shaped or eye-staples), then the device structure can be simplified and optimized for that specific staple type, but the device cannot handle other staple types requiring separate systems and head exchanges
Solution Approach 1:
The stapling head is divided into separate modular components: a driver unit and a driverless unit. The driver unit can be exchanged depending on the staple type required, while the driverless unit remains fixed. This segmentation allows the device to handle both conventional U-shaped staples and eye-staples using a single system, eliminating the need for complete head exchanges while maintaining structural optimization for each staple type.
2Adaptability or versatility
If the complete stapling head is exchanged to change staple types, then the device can adapt to different staple requirements, but the exchange process becomes labor-intensive, complicated, and time-consuming
Solution Approach 1:
By segmenting the stapling head into exchangeable driver units and a fixed driverless unit, the patent enables rapid replacement of only the necessary component (the driver unit) rather than the entire stapling head. This significantly reduces retooling time and simplifies the adaptation process for different staple types.
Solution Approach 2:
The driver unit is designed with dynamic exchangeability, allowing it to be quickly removed and replaced based on the staple type requirements. This dynamic design enables the device to adapt to different staple types without permanent reconfiguration, reducing downtime and increasing operational flexibility.
3Adaptability or versatility
If multiple complete stapling heads are maintained for different staple types, then the device can provide different stapling types simultaneously, but the device complexity and cost increase significantly
Solution Approach 1:
The driverless unit is designed as a universal component that can work with different driver units for various staple types. This universal design allows a single stapling device to perform multiple functions (handling both conventional U-shaped staples and eye-staples) without requiring multiple complete stapling heads, thereby reducing system complexity and cost while maintaining versatility.

AI summary
The invention relates to a device for stapling printed products, preferably automatically, comprising a stapling head for driving a staple through a printed-product back and a bender for bending the open ends of the staple. Said device is characterized in that the stapling head has a modular design, wherein the stapling head comprises a driving tool (1) and a driving-tool holder (2) for equipping with the driving tool, and wherein the driving tool can be fastened to the driving-tool holder in an exchangeable manner, e.g., by means of locking bolts (3) fastened to a crossmember (4) or by means of a groove (5)/feather-key connection. The invention further relates to a corresponding stapling head.
