Bag Stack Gripping Assembly for Precise Box Loading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for boxing stacks of sacs or bags lack precision and evenness in arrangement, are inefficient for lightweight materials, and require additional handling steps, leading to improper deposition and increased boxing times.
Innovation Solution
A system with a manipulator and gripping assembly that retains stacks in an extended position, allowing precise placement into boxes, adaptable to various sizes and materials, ensuring even distribution and matching production rates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If stacks are released and fall into the box by gravity, then boxing operation is simple, but arrangement evenness and precision deteriorate
Solution Approach 1:
The patent applies preliminary action by pre-positioning the stack within the box using the manipulator before release, rather than relying solely on gravity. The stack is held in an extended position and carefully placed into the box, ensuring proper arrangement before the boxing operation completes. This resolves the contradiction by maintaining operational simplicity while achieving precise arrangement through advance positioning.
Solution Approach 2:
The manipulator serves as an intermediary between the gravity-based dropping system and the stack. It provides controlled support during the boxing operation, allowing the stack to be gently placed into the box rather than simply dropped. This intermediary mechanism ensures both ease of operation and precise arrangement by mediating the transfer process.
2Ease of operation
If box flaps are open during boxing, then access to box is easy, but product deposition precision deteriorates
Solution Approach 1:
The manipulator performs preliminary positioning of the stack within the box volume before release, ensuring precise deposition even with open flaps. The stack is carefully placed in the correct position and orientation before being released, eliminating the need to close flaps for precision while maintaining ease of access.
3Shape
If box rotation is required to align stacks, then proper orientation is achieved, but boxing time increases
Solution Approach 1:
The manipulator performs preliminary orientation of the stack in the extended position before insertion into the box. By pre-aligning the stack during the gripping phase, the system eliminates the need for time-consuming box rotation operations, achieving proper orientation while reducing boxing time.
4Ease of operation
If gripping system releases stack outside box, then release area is accessible, but arrangement order deteriorates
Solution Approach 1:
The manipulator acts as an intermediary that maintains control of the stack during movement into the box and only releases it once properly positioned inside the box volume. This ensures arrangement order is maintained while still providing accessible release, as the manipulator can be positioned over the box opening for easy operation.

AI summary
A method for arranging sacs or bags exiting from their production line in boxes or containers (13), wherein such sacs or bags are stacked on each other, provides for collecting each stack of sacs or bags or product (1) from a preferably movable work surface (2) through movable gripping members (40) arranged above such surface (2), said members (40) retaining the sacs or bags of the stack (1) at opposite ends of the latter and transferring the stack into a corresponding box (13) retaining it until therein, so as to arrange such stack in the box. The system (S) provides for movable means (40) for gripping each stack of sacs or bags (1) which transfer the stack of product (1) from the exit of the production line until inside the box (13) leaving it in the latter.
