Hydraulic Grain Bag Winder Core Extraction for Coil Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing grain bag unloading systems require manual unwinding and removal of the entire length of the grain bag from the winder tube, which is time-consuming and creates a larger mass of grain bag for disposal.
Innovation Solution
A base grain bag rolling system with a wheeled frame and rotatable winding tube that separates from the grain bag coil, allowing it to be easily removed without unwinding, using hydraulic cylinders for linear movement and rotation.

Engineering Contradiction Analysis
1Productivity
If manual unwinding and removal of the entire length of grain bag from winder tube is used, then the grain bag can be removed from the system, but the process is time-consuming and requires significant manual effort
Solution Approach 1:
The invention divides the grain bag removal process into two independent stages: (1) the grain bag is emptied and wound onto the winder tube during normal operation, and (2) the winder tube with the coiled bag is automatically extracted and dropped as a complete unit. This segmentation eliminates the time-consuming manual unwinding step while maintaining complete bag removal capability.
Solution Approach 2:
The winder tube is designed to accumulate and coil the entire length of the grain bag during the emptying process, preparing the bag for removal in advance. By the time removal is needed, the bag is already packaged in a compact coiled form on the winder tube, ready for immediate extraction without requiring unwinding during the removal operation.
2Ease of operation
If the entire length of grain bag is unwound for removal, then the bag can be taken off the winder tube, but a larger mass of grain bag is created for disposal
Solution Approach 1:
The grain bag is coiled and nested around the winder tube, forming a compact cylindrical package. This nesting arrangement minimizes the volume and mass footprint of the removed bag, allowing it to be handled and disposed of as a single compact unit rather than an unwound mass.
Solution Approach 2:
Instead of removing the bag in its extended linear form (one dimension), the invention utilizes the radial dimension by coiling the bag around the winder tube. This dimensional transformation creates a compact cylindrical form that reduces the effective mass and volume for disposal while maintaining complete bag removal.
3Productivity
If automated core extraction mechanism is implemented, then bag removal efficiency is improved, but device complexity increases
Solution Approach 1:
The invention extracts only the essential function needed for automated removal: the hydraulic cylinder provides linear motion to pull the winder tube outward, and the cam mechanism provides the simple rotational motion to tilt the tube for dropping. By taking out only these essential automated functions and leaving the rest simple, the system achieves improved productivity without excessive complexity.
Solution Approach 2:
The cam-actuated tilt mechanism serves as an intermediary that converts the linear motion from the hydraulic cylinder into the rotational motion needed for dropping the bag. This intermediary mechanism provides automated core extraction functionality using simple, well-understood mechanical components rather than complex automated systems.

AI summary
A device and method for winding/rolling up a grain bag when emptying a grain bag and also for removing a core from a coiled roll of spent grain storage bag so that the coiled roll of spent grain storage bags can be removed from a grain bag unloading assembly without uncoiling or unrolling the coiled roll of spent grain storage bags. The device uses a hydraulic system to extract the core from which the grain bag length is wound around during unloading of the grain storage bag. The core is similarly extendable to allow for rolling subsequent grain storage bags therearound.
