Printing Tower Safety Device Vertical Movement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing printing towers face challenges in providing effective safety devices that are space-efficient, easily stowable, and ensure operator safety, particularly in high arrangements where safety devices may unintentionally block paths or fail to secure the platform properly.
Innovation Solution
A safety device integrated with the base of the printing tower that can be moved vertically and pivotally, ensuring it is always in an optimal position relative to the operator, and can be automated for secure operation, with a drive system allowing it to be swung open for safe access and stowed away when not in use, preventing accidental opening and enhancing safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the safety device is arranged to move vertically together with the base, then the safety device remains in an optimal position relative to the operator, but the device complexity increases due to the coupling mechanism
Solution Approach 1:
The safety device is merged with the base assembly, where the safety device is arranged to move vertically together with the base through a common drive mechanism. This ensures the safety device remains in an optimal position relative to the operator while maintaining a relatively simple overall structure by combining two functions into one integrated unit.
2Volume of moving object
If the safety device can be moved relative to the base, then space efficiency is improved by allowing the safety device to be stowed away, but the device complexity increases due to additional movement mechanisms
Solution Approach 1:
The safety device is designed with dynamic positioning capabilities, allowing it to move relative to the base between a working position and a stowed position. This relative movement is achieved through a simple pivot or slide mechanism that enables the safety device to be swung open or folded away, optimizing space utilization without requiring complex automated systems.
3Ease of operation
If the safety device is arranged to swing open for access, then ease of operation is improved for maintenance, but the reliability decreases due to potential accidental opening
Solution Approach 1:
The safety device incorporates a preliminary locking action where the safety device must be deliberately unlocked before it can swing open. This preliminary action prevents accidental opening during operation while still allowing easy access for maintenance when intentionally opened. The locking mechanism may include a latch or clamp that secures the safety device in place during normal operation.
4Reliability
If the safety device is always in a secured position during operation, then reliability is improved by preventing hazards, but the ease of operation decreases for maintenance access
Solution Approach 1:
The safety device transitions from a static secured position to a dynamic configuration that allows easy access during maintenance. The safety device can be swung open or folded away from its secured position, providing operators with unobstructed access to maintenance areas while maintaining a simple return-to-secured-position mechanism that ensures reliability during operation.

AI summary
The invention relates to a printing tower of a press, which can be divided into two side frames, wherein a platform can be moved in the vertical direction between the two side frames, and wherein a securing device is provided, one securing device being constructed as a crash safeguard and being designed such that said device can be moved together with the platform in the vertical direction, and wherein the securing device can be moved relative to the platform. The invention also relates to a method for providing a platform of a printing tower of a press, which is divided by one movable side frame being moved relative to another side frame and, as a result, an intermediate space being created, and a lifting device arranged in the intermediate space and released by the displacement conveying the platform into the intermediate space in the vertical direction into a desired position. Following the displacement of the mobile side frame, a securing device is moved relative to the platform and the securing device, together with the platform, is moved in the vertical direction.
