Container Transfer Buffer Synchronizes Processing Stations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing container transfer devices between processing stations, such as blow molding and labeling machines, face issues with gaps in the container stream due to faulty or defective bottles, leading to intermittent operation and potential stoppages in downstream processing stations.
Innovation Solution
A device with two transfer units, a buffer system, and controllable transport units that accumulate and release containers synchronously with the second processing station, ensuring continuous operation even with intermittent delivery from the first station, using a combination of drive units, detection systems, and passive gripping mechanisms to manage container flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If containers are transferred directly from the first processing station to the second processing station without buffering, then the transfer device is simple and fast, but gaps in the container stream cause interruptions in the second processing station
Solution Approach 1:
The buffer stores containers in advance before they are needed by the second processing station. When containers arrive from the first processing station, they are temporarily held in the buffer, ensuring that the second station always has containers available, thus preventing interruptions and maintaining continuous operation.
Solution Approach 2:
The buffer acts as an intermediary element between the first and second processing stations. It decouples the two stations, allowing the second station to operate continuously regardless of intermittent delivery from the first station, thereby resolving the contradiction between reliability and device complexity.
2Productivity
If a buffer system is introduced to ensure continuous operation, then interruptions are prevented, but the device complexity and space requirements increase
Solution Approach 1:
The buffer utilizes vertical space by stacking containers one above another instead of spreading them out horizontally. This dimensional change allows the buffer to store multiple containers in a compact vertical arrangement, maintaining continuous processing capability while minimizing the floor area occupied by the buffer system.

AI summary
The transfer device (10) is provided with a transfer unit (50), where a buffer (26) is provided with individual transfer units for the container (40). The transport units are movably controlled in such a way that the buffer interacts with the machining station in such a way that transfer of the container from the buffer to the machining station (22) takes place with chronological synchronizm.
