Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for handling film-like cover strips on packaging material webs are bulky due to separate units for punching holes, separating cover strips, and connecting them to the web, leading to inefficient space usage.
Innovation Solution
A compact device design where the units for forming holes, separating cover strips, and connecting them to the packaging material web are integrated on a common frame with a movable carrier element, allowing for precise positioning and adjustment based on sensor feedback, enabling simultaneous processing of multiple webs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If separate devices are used for punching holes, separating cover strips, and connecting them to the web, then each device can be optimized for its specific function, but the overall space requirement becomes large
Solution Approach 1:
The patent combines three separate devices (punching device, separating device, and connecting device) into a single integrated device with a common frame. This merging eliminates the need for multiple separate installations, significantly reducing the overall space requirement while maintaining all necessary functions for processing packaging material webs and cover strips.
Solution Approach 2:
The integrated device performs multiple functions simultaneously - punching holes in the web, separating cover strip sections, and connecting cover strips to the web - all within a single multi-functional unit. This universal design allows one device to replace three separate devices, optimizing space utilization while preserving functional capabilities.
2Area of stationary object
If devices are integrated on a common frame, then space requirements are reduced, but the complexity of positioning and alignment increases
Solution Approach 1:
The device incorporates movable carrier elements that can be adjusted in position along the common frame. This dynamic positioning capability allows the punching, separating, and connecting devices to be precisely aligned with the moving web and cover strips during operation, simplifying the positioning task while maintaining integration benefits.
Solution Approach 2:
The system uses sensors to detect the position of the web and cover strips and provides feedback to the control system. This feedback mechanism enables automatic adjustment of the movable carrier elements to ensure precise alignment, reducing the complexity of manual positioning while maintaining high integration levels.
3Ease of operation
If the position of devices is fixed, then alignment is simple, but adaptability to different web formats and hole positions is limited
Solution Approach 1:
The carrier elements supporting the punching, separating, and connecting devices are designed to be movable rather than fixed. This allows the devices to be repositioned along the frame to accommodate different web widths, hole positions, and cover strip dimensions, providing adaptability to various packaging formats while maintaining simple alignment procedures through controlled movement.
Solution Approach 2:
The device allows adjustment of key parameters such as the position of the punching device, the separation point of the cover strip, and the connection location on the web. By enabling parameter changes, the system adapts to different packaging requirements without requiring complete reconfiguration, balancing operational simplicity with format versatility.

AI summary
The invention relates to a device (10) for handling a film-like cover strip (1) on a packaging material web (2) for a packaging container, comprising a first device (20) for forming a through-hole in the packaging material web (2), a second device (25) for separating one section of the cover strip (1) and a third device (40) for joining the separated sections of the cover strip (1) to the packaging material web (2) in the region of the through-hole. The section of the separated cover strip (1) covers the through-hole. According to the invention, said three devices (20, 25, 40) are arranged on a common station (13) which comprises a frame (11) on which the position of at least one of the three devices (20, 25, 40) can be altered with respect to the packaging material web (2).
