Lifting Table Stacker Motorized Format Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lifting table destackers require time-consuming manual format adjustments for changes in container height and diameter, limiting efficiency and reliability during the stacking process, especially when integrated with welding devices for container bodies.
Innovation Solution
The implementation of motorized adjustments for both the stacking unit and guide elements allows for rapid format changes, ensuring optimal positioning and uninterrupted operation by automatically adapting to new product dimensions through vertically arranged pivotable pawls and motor-driven guide elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual format adjustment is used for the stacking unit and guide elements, then device complexity is reduced, but productivity decreases due to time-consuming format changes
Solution Approach 1:
The patent applies dynamics by making the stacking unit and guide elements adjustable through motorized mechanisms. The stacking unit can be positioned at different locations along the package length, and the guide elements can be adjusted to different heights and positions, allowing the system to dynamically adapt to various package formats while maintaining high stacking speed
Solution Approach 2:
The patent implements parameter changes by enabling motorized adjustment of the stacking unit position and guide element dimensions. The control unit receives format data and automatically adjusts parameters such as stacking unit location, guide element height, and guide element position to match the new package format, eliminating manual adjustment time
2Loss of time
If manual format adjustment is used, then ease of operation is improved, but loss of time increases during format changes
Solution Approach 1:
The patent applies self-service by implementing an automatic control system that receives format data (either manually entered or from external sources) and automatically adjusts the stacking unit and guide elements to the correct positions. The system serves itself by eliminating the need for operators to manually adjust each component, reducing changeover time while maintaining operational simplicity through automated control
Solution Approach 2:
The patent implements feedback by using a control unit that receives format data and automatically adjusts the stacking unit and guide elements based on this information. The system monitors the format requirements and makes precise adjustments to match the new package dimensions, ensuring accurate positioning without manual intervention
3Reliability
If the stacking unit position is not adjusted, then device complexity is reduced, but reliability decreases due to improper positioning
Solution Approach 1:
The patent applies dynamics by making the stacking unit position adjustable along the package length through motorized mechanisms. The stacking unit can be dynamically repositioned to accommodate different package formats, ensuring it is always optimally positioned for reliable stacking operations regardless of the package dimensions
Solution Approach 2:
The patent replaces manual mechanical adjustment with motorized actuation and electronic control. Motors drive the stacking unit and guide elements to their correct positions based on control unit commands, providing precise and reliable positioning without the imprecision and time consumption of manual adjustment

AI summary
In a lifting table stacker (1), a lifting table (3) is provided with a holding device (4) arranged above it for a package (10) of the product to be stacked. The holding device positions the package by means of motor-adjustable guide elements (14, 15), and a stacking unit, in particular a suction unit (6), is provided whose position above the package (10) is also motor-adjustable. The motor-adjustable guide elements and the stacking unit result in a lifting table stacker with very rapid format changes. Such a lifting table stacker is used to feed sheet metal into a rotary device, which is connected upstream of a resistance seam welding machine for container sides.
