Dual Bagmaking And Packaging Layout for Narrower Installation Space
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing combination weighing and bagmaking systems require a wide installation space due to the dimensions of the bagmaking and packaging machines, which are not adequately addressed by existing solutions.
Innovation Solution
The bagmaking and packaging apparatus is designed with two machines installed side by side, featuring a compact layout with a rearward housing unit for the control circuit, symmetrical structure, and partition plates to minimize width and facilitate maintenance, while using a gap-closing member to prevent debris accumulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If two bagmaking and packaging machines are installed side by side under a combination weighing apparatus, then the system can process multiple products simultaneously, but the width of the installation space increases
Solution Approach 1:
The patent repositions the housing unit from a lateral arrangement to a rearward arrangement along the depth dimension of the bagmaking machine. This dimensional shift allows the control components to be located in the rear portion of the machine rather than extending the width, thereby maintaining compact lateral dimensions while accommodating all necessary control functions for dual-machine operation
Solution Approach 2:
The patent integrates the control unit housing into the existing bagmaking machine structure rather than treating it as a separate component. The housing unit containing the circuit board is merged with the machine body, and the circuit board is further integrated with other control components, reducing the number of separate elements and optimizing space utilization
2Ease of operation
If the control unit circuit board is installed on the left or right side of the bagmaking machine, then it is easily accessible, but the machine width increases
Solution Approach 1:
The control unit accessibility is maintained by positioning the housing unit in the rear portion of the machine where it can be accessed from the rear side. This shifts the access direction from lateral (left/right) to depthward (rear), allowing maintenance personnel to reach the circuit board without increasing the machine's lateral footprint
3Device complexity
If partition plates are not installed between the two bagmaking machines, then the structure is simpler, but debris can fall onto critical components
Solution Approach 1:
Partition plates are installed between the two bagmaking machines as intermediary structures that prevent debris from falling onto critical components. These plates act as protective barriers positioned strategically to block debris paths while maintaining overall structural simplicity and not interfering with the normal operation of either machine

AI summary
Two bagmaking and packaging machines are installed side-by-side. Each of the bagmaking and packaging machines includes a film supply unit in the rear portion, a former mechanism in the front portion, and a transverse sealing mechanism that transversely seals a top and a bottom of the film in the tubular shape into which a product supplied from a combination weighing apparatus is fed. Each of the bagmaking and packaging machines is disposed under a discharge chute of a corresponding combination weighing machine, which includes two combination weighing machines joined to each other substantially symmetrically in the left and right direction as viewed from above and a base member that supports the combination weighing machines. A maximum width of the bagmaking and packaging apparatus when viewed from the front is narrower than a width of the base member.
