Solution Overview
Problem
Existing methods for producing plastic containers with non-circular cross-sections, such as elliptical or rectangular shapes, face challenges in labeling and filling due to alignment precision requirements, which can lead to inefficiencies and potential damage during processing.
Innovation Solution
A device comprising a forming device, a filling device, and an alignment device that transforms plastic preforms into containers with non-circular cross-sections, featuring a transport device with gripper elements and an alignment mechanism that rotates and aligns containers to a uniform rotary position, ensuring precise alignment for subsequent filling and labeling processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If containers with non-circular cross-section are produced using special blowing machines, then the container shape is achieved, but alignment precision for filling and labeling deteriorates
Solution Approach 1:
The device separates the forming function and alignment function into distinct modules: the blowing machine produces containers with non-circular cross-sections, while a separate alignment device with adjustable guide elements corrects the rotational position. This segmentation allows each module to optimize its specific function without compromising the other.
Solution Approach 2:
An alignment device acts as an intermediary between the forming machine and the filling/labeling machines. This intermediary component receives containers with variable rotational positions and outputs containers with standardized alignment, enabling downstream equipment to operate with consistent precision regardless of upstream variations.
2Device complexity
If containers are transported with variable angular precision, then the transport process is simpler, but filling and labeling efficiency deteriorates
Solution Approach 1:
The alignment device incorporates adjustable and movable guide elements that can adapt to different container types and rotational positions. This dynamic capability allows the same device to handle various container shapes while maintaining consistent alignment precision, thereby preserving productivity without requiring overly complex specialized equipment for each container type.
3Speed
If containers are not precisely aligned, then the processing speed may be maintained, but the risk of damage during filling and labeling increases
Solution Approach 1:
The alignment device performs preliminary alignment of containers before they enter the filling and labeling stations. By correcting rotational positions in advance, the system ensures that subsequent high-speed processing operations can proceed at optimal speeds without compromising container integrity, as all containers are pre-positioned within the safe alignment tolerance range.

AI summary
A device for production of drinks containers may include a forming device which transforms plastic preforms into plastic containers, a filling device which is arranged after the forming device in the transport direction of the plastic containers and fills the plastic containers with a fluid, and a transport device which transports the plastic containers individually from the forming device in the direction of the filling device along a prespecified transport path. The device includes, along the transport path, an alignment device which aligns the plastic containers at least partially in relation to a rotary position about their longitudinal axis.
