Rotary Transport Frame for Sack Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for turning over objects, particularly packages of stacked sacks, face delays in transportation and complex mounting requirements due to the need for stationary transport drives and friction-fit connections, which hinder efficient and fast operation.
Innovation Solution
A device with a holder and rotary mechanism where the transport drive is integrated with a rotatable frame, allowing continuous movement and rotation of transport elements, eliminating the need for cushioning and simplifying the connection between the drive and elements using toothed belts and rollers, and incorporating pneumatic cylinders for adjustment and dampening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If transport elements are hoisted out of the transport plane before turning, then the object can be gripped and turned over, but the transport of objects is delayed
Solution Approach 1:
The transport drive is made dynamically movable with the frame through torque-proof fastening, allowing it to adapt its position during the turning operation. This dynamic configuration enables continuous driving action while the frame rotates, eliminating the need to halt transport for gripping operations and maintaining high productivity throughout the cycle
2Ease of operation
If a stationary transport drive is used to drive transport elements, then the transport elements can be turned over, but the mounting becomes complicated and additional complicated components are required
Solution Approach 1:
The transport drive is merged with the frame by fastening it in a torque-proof manner directly to the frame. This combination eliminates the need for separate stationary mounting structures and complex cushioning components, as the frame itself provides the necessary support and movement accommodation for the transport drive during operation
Solution Approach 2:
The transport drive is positioned to move with the frame, maintaining a constant functional relationship with the transport elements throughout the turning cycle. This equipotential positioning eliminates the need for complex cushioning mechanisms to accommodate positional variations between the drive and transport elements
