Bag Bundle Conveyance Apparatus Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bag bundle conveyance methods face instability and collapse during transport, particularly due to inertia and gravity, leading to separation and bending of bags, especially when thick portions are involved.
Innovation Solution
A bag bundle conveyance apparatus and method that uses a support body to stabilize the bundle from below and a holding unit to maintain its position, allowing for controlled movement in the conveyance direction, preventing collapse and bending by ensuring continuous support and contact with the conveyance belt.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a conveyance belt is used to convey the bag bundle, then the conveyance is simple and continuous, but the posture of the bag bundle becomes unstable and may collapse under inertia
Solution Approach 1:
The patent combines the conveyance belt (support body) with a holding unit that directly contacts the bag bundle. The holding unit nips the bag bundle while the conveyance belt supports it from below, creating a merged support system that provides both continuous conveyance and posture stability, preventing collapse under inertia
Solution Approach 2:
The holding unit acts as an intermediary between the conveyance belt and the bag bundle. It transfers the support force from the conveyance belt to the bag bundle while maintaining stable contact, ensuring the bag bundle posture remains stable during conveyance
2Device complexity
If only a narrow range of the bag bundle is directly held by the holding unit, then the holding unit can be compact, but some bags may unintentionally bend when the bag bundle is placed
Solution Approach 1:
The holding unit applies localized nipping force to specific portions of the bag bundle while the conveyance belt provides distributed support from below. This local quality approach allows the holding unit to be compact while the combined system prevents bag bending through coordinated local and distributed support
3Ease of operation
If the bag bundle is lifted while being held, then the bag bundle can be repositioned, but the posture may change significantly under gravity
Solution Approach 1:
The patent merges the lifting function with the holding function by having the holding unit lift the bag bundle while maintaining its nipping contact. Simultaneously, the conveyance belt continues to support the bag bundle from below, ensuring posture stability is maintained even during repositioning operations

AI summary
A bag bundle conveyance apparatus which conveys a bag bundle including a plurality of bags, includes: a support body which supports the bag bundle from below; a holding unit which holds the bag bundle; and a transfer drive unit which moves the holding unit in a conveyance direction, wherein the transfer drive unit moves the holding unit in the conveyance direction in a state where the bag bundle is supported from below by the support body and is held by the holding unit, in such a manner that the bag bundle is conveyed in the conveyance direction.
