Palletizing Device Independent Vertical Stations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing palletizing devices lack the necessary degrees of freedom and compactness for universal applicability and have limited palletizing speeds due to restricted vertical movement and interdependence of transfer and loading stations.
Innovation Solution
A palletizing device with independently vertically movable transfer and loading stations, each with separate guide and drive systems, allowing for precise and independent vertical adjustment and movement, enabling flexible positioning and increased speed in palletizing operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If transfer and loading stations are arranged on a single lifting mechanism column, then device compactness is improved, but vertical movement independence deteriorates
Solution Approach 1:
The single lifting mechanism column is segmented into two independent lifting mechanisms, each capable of independently controlling the vertical position of the transfer station and loading station. This segmentation allows both stations to move vertically independently while maintaining compact arrangement on the same column structure.
Solution Approach 2:
The system transitions from static or interdependent vertical positioning to dynamic independent control, where each station can adjust its vertical position autonomously based on operational requirements, enabling adaptation to different inlet configurations and palletizing speeds.
2Device complexity
If transfer and loading stations share common guide and drive devices, then device complexity is reduced, but palletizing speed deteriorates
Solution Approach 1:
The common guide and drive devices are segmented into separate independent systems for the transfer station and loading station. Each station has its own guide rails and drive mechanism, eliminating mechanical interference and enabling simultaneous independent operation, which increases overall palletizing speed.
3Device complexity
If loading station cannot be lowered below transfer station level, then structural simplicity is improved, but universality deteriorates
Solution Approach 1:
The loading station is equipped with an independent lifting mechanism that enables it to be lowered below the transfer station level when required. This dynamic positioning capability allows the system to accommodate different inlet configurations, including bottom inlets and side inlets, enhancing universality while maintaining structural simplicity.

AI summary
A palletizing device (10) with a vertically movable transfer station (14) is disclosed, which is connected to an upstream infeed device (18) for conveying items, unit loads, containers (20), or the like to be palletized. Downstream of the transfer station (14) in the conveying direction (22) is a vertically movable loading station (16), which is connected to a stacking station (28) for palletizing the items, unit loads, and/or containers (20). The transfer (14) and loading stations (16), which are independently adjustable in their vertical positions, are assigned to a common support structure, which each has separate guide devices (30) for vertically movable guidance and drive devices for vertically adjusting the position of the transfer (14) and loading stations (16).Furthermore, a method for handling such a palletizing device (10) is disclosed, in which the support planes (26, 48) of the transfer (14) and loading stations (16) are approximately aligned with each other at least during a transfer of an article, unit load and/or container layer (21) between the two stations (14, 16).
