Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing packaging machines require significant space for separating and processing stacks of open-mouth bags, limiting their capacity and efficiency.
Innovation Solution
A compact processing device that grips and offsets the topmost open-mouth bag from the stack, allowing for efficient separation and marking, with a marker device positioned for easy access and minimal additional space, using a bag conveying device with a suction or friction mechanism to handle the bags efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a chain grate traveling around the magazine and multiple conveying devices are used to separate and transfer open-mouth bags, then reliable bag separation is achieved, but the space requirement and device complexity increase significantly
Solution Approach 1:
The bag conveying device is divided into multiple functional zones (gripping zone, offset zone, marking zone) within a compact footprint. The device segments the bag handling process into discrete steps that occur in sequence within a small area, eliminating the need for large traveling chain grates and multiple separate conveying devices.
Solution Approach 2:
The invention transitions from a linear horizontal arrangement of multiple large conveying devices to a compact arrangement where the bag moves through different functional zones within a single device. The offset position allows the marker device to access the bag from a different spatial dimension, reducing the overall footprint while maintaining all necessary functions.
2Productivity
If multiple large conveying devices and a placement device are positioned in line, then complete bag processing is achieved, but the device complexity and space occupation increase
Solution Approach 1:
The invention merges the functions of multiple separate conveying devices and the placement device into a single integrated bag conveying device. The device combines gripping, offset positioning, and marking functions in one unit, eliminating the need for multiple independent devices positioned in line while maintaining full processing capability.
Solution Approach 2:
The bag conveying device is designed as a multi-functional device that performs gripping, offset positioning, and coordinates with the marker device for marking. This universal device replaces several specialized devices, reducing overall system complexity while maintaining productivity through integrated multi-functionality.
3Ease of repair
If the marker device is positioned for easy access, then maintenance accessibility is improved, but additional space may be required
Solution Approach 1:
The marker device is positioned at the offset location where bags are temporarily positioned during conveying. This local positioning allows the marker to access bags at a convenient point in the process while the compact offset design ensures that the additional space required is minimal and integrated into the overall device footprint rather than requiring separate dedicated space.

AI summary
A processing device and method for processing a stack of bags having a multitude of open-mouth bags are provided, including a stacking device on which the stack of bags can be disposed in a base position, wherein the open-mouth bags of the stack have a bag length and an open filling mouth at one end. A marker device and a bag conveying device are provided that are suitable and provided for gripping the topmost open-mouth bag of the stack in the base position and displacing it to a take-up position that is only partially supported on the stack of bags and putting at least one mark on the open-mouth bags in the take-up position.
