Receiving Box with Segmented Suction for Open Bag Filling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for filling open-mouth bags with bulk materials face challenges in achieving reliable sealing and flexibility in handling, particularly when dealing with low-weight bags used for materials like cement or tile grout.
Innovation Solution
An apparatus with a bag receiving unit configured as a receiving box, equipped with suction apertures for form-fit retention and controlled vacuum distribution, allows for efficient and flexible filling of open-mouth bags by ensuring the bag is securely held during the filling process, enabling better sealing and compacting before closure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional manufacturing methods are used to fill open-mouth bags, then the filling process is simple and fast, but the sealing of the filled bulk material is unreliable
Solution Approach 1:
A receiving box is introduced as an intermediary device between the bag opening and the filling source. The receiving box receives the open bag, holds it in a fixed position, and provides a controlled environment for filling. This mediator enables reliable sealing by ensuring the bag remains properly positioned and open throughout the filling process, while the apparatus maintains relative simplicity through this single added component.
2Ease of operation
If open-mouth bags are filled without form-fit retention, then the filling process is fast, but the handling and compacting of filled bags is difficult
Solution Approach 1:
The receiving box performs preliminary action by receiving and pre-positioning the open bag in a form-fit manner before filling begins. The bag is held open and securely positioned in advance, which facilitates easy handling and compacting during and after filling. This preliminary preparation eliminates the need for complex handling operations during the filling process itself.
Solution Approach 2:
The receiving box provides localized form-fit retention at the bag opening area while allowing the rest of the bag to remain free. This localized control enables easy handling and compacting of the filled bag by maintaining the opening in a specific configuration only where needed, without constraining the entire bag structure.
3Reliability
If multiple suction apertures are used in the receiving box, then the bag is securely held during filling, but the device complexity increases
Solution Approach 1:
The suction apertures in the receiving box are divided into multiple separately controllable groups or zones. This segmentation allows different regions of the receiving box to apply suction independently, providing secure bag retention at multiple locations simultaneously. The segmentation enables reliable bag holding without requiring a single complex suction system, as each aperture or group can be controlled independently through simple valve mechanisms.
