Solution Overview
Problem
Conventional bag clamping devices in material bag filling systems are labor-intensive and unreliable due to manual operation and unstable vacuum suction, leading to high failure rates and increased costs.
Innovation Solution
A bag clamping device with X-axis and Z-axis rails, cantilevers, electric clamps, and blowers that automatically lift and stabilize the filling tube portion of the material bag, combined with a conveyor belt and heat sealer for efficient filling and sealing, utilizing motorized screw rods and a timing belt for precise control and synchronization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual operation is used to place the material bag on the clamp, then the device complexity is reduced, but the productivity decreases and labor cost increases
Solution Approach 1:
The blowers are activated before the clamping operation to inflate the filling tube portion of the material bag, making it rigid and easier to clamp. This preliminary inflation action enables the automated clamping system to work more effectively, resolving the contradiction by preparing the object in advance for the main operation.
Solution Approach 2:
The patent replaces manual mechanical operation with an automated system comprising electric clamps, blowers, and a control unit. The electric clamps provide automated clamping force, while the blowers provide pneumatic support to maintain the filling tube's rigidity, thereby increasing productivity while managing device complexity through systematic automation.
2Ease of operation
If vacuum suction is used through the automatic gripper to open the material bag, then the ease of operation is improved, but the reliability decreases due to unstable vacuum suction and high failure rate
Solution Approach 1:
The patent extracts the unreliable vacuum suction function from the system and replaces it with a more reliable approach. Instead of relying on vacuum suction to hold and open the bag, the system uses blowers to inflate the filling tube, creating a rigid structure that can be reliably clamped and opened by the electric clamps, thereby improving reliability while maintaining ease of operation.
Solution Approach 2:
The patent uses pneumatic pressure from blowers to inflate the filling tube portion of the material bag, making it rigid and easier to manipulate. This pneumatic approach replaces the unreliable vacuum suction system, providing more stable and controllable bag opening and clamping operations, thus improving reliability.
3Reliability
If the filling tube portion is not inflated, then the device complexity is reduced, but the clamping stability worsens because the tube cannot be firmly clamped
Solution Approach 1:
The blowers are activated before the clamping operation to inflate the filling tube portion, making it rigid and easier to clamp. This preliminary inflation action enables the automated clamping system to work more effectively, resolving the contradiction by preparing the object in advance for the main operation.
Solution Approach 2:
The blowers serve multiple functions: they inflate the filling tube to provide rigidity for clamping, support the automated clamping operation, and enable reliable positioning. This multi-functionality justifies the added device complexity by providing clamping stability across multiple operational phases.
