Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bag filling and sealing technologies require multiple stations and complex handling processes, leading to inefficiencies and increased operational complexity.
Innovation Solution
A device comprising a sealing bar, pressure bar, actuator, and retaining means that allows for simultaneous filling and sealing of bags by moving the sealing bar and pressure bar relative to each other, with mechanical coupling enabling the opening and closing of the bag's filling openings, facilitating a compact and efficient operation without transferring the bag between stations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple stations are used for filling and sealing operations, then the bag can be processed through dedicated stations, but the device complexity and handling complexity increase
Solution Approach 1:
The patent combines the filling station and sealing station into a single integrated device. The sealing bar and pressure bar are positioned adjacent to each other within the same device housing, allowing both filling and sealing operations to be performed in one location without transferring the bag between separate stations. This merging eliminates the need for multiple independent stations while maintaining reliable processing through coordinated operation of the bars.
Solution Approach 2:
The device performs multiple functions within a single unit: the first retaining means holds the bag during filling, the sealing bar performs sealing operations, and the pressure bar applies pressure during both filling and sealing. The mechanical coupling system coordinates these different functions, allowing the device to handle both filling and sealing tasks universally without requiring separate specialized stations.
2Productivity
If multiple stations are used for filling and sealing, then each operation can be optimized independently, but the handling time and operational complexity increase
Solution Approach 1:
The device enables continuous operation by eliminating the transfer time between separate filling and sealing stations. The bag remains in position within the same device, allowing the filling operation to transition directly into the sealing operation without interruption. The mechanical coupling ensures that the retaining means, sealing bar, and pressure bar coordinate their actions continuously, maintaining productive operation throughout the entire process.
3Volume of moving object
If the sealing bar and pressure bar are positioned close to each other, then the device becomes compact, but the bag handling and opening/closing mechanism becomes more complex
Solution Approach 1:
The mechanical coupling system is nested within the compact device structure. The coupling mechanism is integrated into the housing and connects the sealing bar and pressure bar assemblies in a space-efficient manner. This nesting allows the complex mechanical coupling to be contained within the compact overall device volume without requiring additional external space.

AI summary
An apparatus for filling and sealing a bag with a filling opening, comprising a drive which is arranged for moving a sealing bar (13) relative to a pressure bar (23) between a clamping position and a rest position, first retaining means (11, 21) and second retaining means (12, 22) for retaining the bag on both sides of the filling opening, a drive and a mechanical coupling for coupling the movement of the clamping position to the rest position of the sealing and/or pressure bar to a movement of the first retaining means with respect to the second retaining means.
