Parallel Bag Holding Module With Telescopic Linkage for Compact Packing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing packaging machines suffer from inefficient and unstable packaging production due to complex structures, large footprints, and the need for sequential processing of multiple bags, leading to excessive travel time and space occupation.
Innovation Solution
A conveying module for packaging machines featuring a modular pedestal with parallel holding units and a telescopic linkage mechanism that allows synchronized adjustment of holding components to accommodate multiple bags simultaneously, along with a bag width adjusting mechanism to adapt to different sizes, ensuring efficient and stable packaging operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a serial type circulating conveyor mechanism with multiple stations is used to process multiple bags simultaneously, then the packaging processing capacity is improved, but the overall return travel becomes overlong and the structure becomes complex
Solution Approach 1:
The conveying device is divided into multiple independent conveying modules, each capable of processing one bag. These modules are arranged in parallel on the circulating conveyor mechanism, allowing simultaneous processing of multiple bags without increasing the return travel length of the conveyor itself.
Solution Approach 2:
Instead of arranging processing stations sequentially along the conveying direction (serial arrangement), the patent uses a parallel arrangement where multiple holding units are positioned side-by-side perpendicular to the conveying direction. This dimensional change allows multiple bags to be processed simultaneously without extending the conveyor's return travel.

3Productivity
If offline mechanisms such as bag loading, opening, charging, sealing and discharging are arranged in turn along the conveying direction, then multiple bags can be processed simultaneously, but each bag needs to travel across the travel length covered by a plurality of stations, resulting in large traveling time

The conveying device is divided into multiple independent conveying modules, each capable of processing one bag. These modules are arranged in parallel on the circulating conveyor mechanism, allowing simultaneous processing of multiple bags without increasing the return travel length of the conveyor itself.

AI summary
A conveying module and a conveying device for a packing machine are provided. The conveying module for the packing machine is provided on the circulating conveyor mechanism, and includes a modular pedestal on which a telescopic linkage mechanism and at least two holding units arranged in parallel for placing packing bags are provided. Each holding unit includes left and right holding components engaged with sides of the packing bag and movable relative to each other. The telescopic linkage mechanism synchronously is configured to enable the left and right holding components to move relative to each other, so as to drive all the holding units to synchronously switch between a bag deployed attitude and a bag retracted attitude. The spacing distance of the left and right holding components in the bag deployed attitude is larger than that in the bag retracted attitude.
