Integrated Pusher and Sealing Unit for High-Speed Packaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional automatic filling and packaging devices have limitations in production speed due to fixed positions of components, leading to increased production time and defective products, particularly when high-speed operations are attempted, as the sealing process is prone to failures and variations in packaging bag folding.
Innovation Solution
The integration of a pusher member, gusset nails, and a blade-equipped sealing device into a unit main body that can move freely, allowing simultaneous filling, folding, and sealing of packaging bags, separating the ejection step from the sealing process to enhance operational efficiency and reduce defects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the pusher member moves forward and backward while other components remain fixed, then the sealing process can be completed, but the total time for filling and sealing one article is long, limiting production speed
Solution Approach 1:
The patent combines the pusher member, gusset forming means, and blade-equipped sealing device into a single integrated unit that moves together as one assembly. This merging of components allows all three operations (filling, folding, and sealing) to be performed simultaneously during the same movement cycle, eliminating the need for separate sequential operations and thereby reducing total processing time while increasing production speed.
Solution Approach 2:
The patent makes the sealing device dynamic by allowing it to move forward and backward along with the pusher member, rather than remaining fixed. This dynamic configuration enables the sealing device to perform its function during the movement cycle itself, converting what would have been a stationary, time-consuming operation into a dynamic, time-efficient process that occurs concurrently with other operations.
2Reliability
If air suction is used to fold the opening end portion into a gusset shape, then the packaging bag can be sealed, but variations in the folding finish are easily produced, leading to defective products
Solution Approach 1:
The patent replaces the air suction-based folding mechanism with a mechanical gusset forming means that uses physical guides and pressing surfaces to fold the packaging bag opening end portion. This mechanical approach provides more precise control over the folding process, ensuring consistent gusset formation without the variations and defects that occur with air suction methods.
3Productivity
If the pusher member movement speed and ejection speed are increased for high-speed operation, then packaging efficiency is enhanced, but the sealing time is reduced, causing sealing failures
Solution Approach 1:
The patent ensures continuous useful action by designing the integrated unit to perform filling, gusset forming, and sealing operations without interruption during the movement cycle. The sealing device remains engaged with the packaging bag throughout the entire process, maintaining continuous sealing pressure and heat application, which prevents sealing failures even at high speeds by eliminating gaps or interruptions in the sealing action.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution significantly reduces the time required to fill and seal packaging bags, improves yield by minimizing sealing failures, and allows for higher production speeds while maintaining product quality.
Implementation Method 1
a gusset forming means which is provided in the pusher member to fold the opening end portion of the packaging bag into a gusset shape
Implementation Method 2
a blade-equipped sealing device which seals the portion folded with the gusset forming means into the gusset shape while pressing in an up/down direction and heating the folded portion
Implementation Method 3
the air suction source is used to suck air from the suction holes so as to remove air inside the packaging bag

AI summary
An object is to provide an automatic filling and packaging device which enhances the efficiency of packaging work and which suppresses the occurrence of defective products to achieve satisfactory yield.In an automatic filling and packaging device, a locating means, a pair of upper gusset nails, a pair of intermediate gusset nails, a pair of lower gusset nails, and a blade-equipped sealing device are formed into a unit as a unit main body, and the unit main body and the pusher member are formed to be able to freely move close to and apart from each other. In this way, as compared with a conventional automatic filling and packaging device, it is possible to reduce the total time in which one article to be packaged is filled into one packaging bag and then the opening end portion thereof is sealed, with the result that it is possible to enhance the efficiency of packaging work.
