Bagging Machine Pneumatic Opening Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The manual opening of elongated product bags, such as bread bags, is labor-intensive and dependent on operator dexterity, and the variety of bag sizes complicates the process.
Innovation Solution
A mechanized process using a stack of bags with flaps aligned in the same direction, where a pointed member pierces two flaps and a jet of air opens the top bag, allowing easy insertion and tearing to accommodate objects, with a machine comprising mobile and fixed tables, a blower, and adjustable edges to accommodate different sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual opening of bags is used, then operator dexterity is required, but the operation is always long and labor-intensive
Solution Approach 1:
The patent replaces the manual mechanical opening operation with an automated system that uses a jet of air (aerodynamic force) to open the bags. The air jet enters through the flap and inflates the bag from the inside, causing it to open automatically without requiring manual dexterity or time-consuming hand manipulation.
Solution Approach 2:
The invention employs a pneumatic system where a jet of air is directed into the bag through the flap to inflate and open the bag automatically. This pneumatic action eliminates the need for manual opening operations, significantly reducing operation time and increasing productivity while maintaining ease of operation.
2Adaptability or versatility
If multiple bags of different sizes are used, then various product sizes can be accommodated, but the multiplicity of bags complicates the process
Solution Approach 1:
The patent describes a universal bagging system that can handle multiple bag sizes using the same automated mechanism. The air jet system and pointed member can open different bag configurations (single flap, double flap, various sizes) through the same basic process, eliminating the need for separate handling procedures for each bag size and reducing system complexity.
Solution Approach 2:
The invention adjusts parameters such as the angle and position of the air jet, the timing of the opening action, and the pressure applied by the pointed member to accommodate different bag sizes. These parameter modifications allow a single automated system to handle various bag dimensions without increasing operational complexity.
3Extent of automation
If the pointed member pierces flaps to open bags, then automated opening is achieved, but the flaps must be arranged in specific directions
Solution Approach 1:
The patent requires that bags be pre-stacked with flaps arranged in the same direction before the automated opening process begins. This preliminary arrangement ensures that the pointed member can consistently pierce the flaps at the correct angle and position, enabling reliable automated opening without requiring complex real-time adjustment mechanisms.

AI summary
The method involves stacking bags on a table (1) by placing two flaps (V1, V2) and a third flap of the bags in same direction in a lower position. The table is movable and pushed by force (F) against a stop (2) that is fixed and connected to another table (3) and extended above the flaps. The stop is provided with a pointer member (4) or a clip under action to perforate the flaps. The air flow is sent above the tables to open an upper bag to introduce the object by pushing the object to bottom of the bag, so that the object is partially torn and slipped at the action of the tip of the member. An independent claim is also included for a machine for bagging object using bags.
