Carousel Packaging Machine Modular Seat Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing packaging machines with horizontal-axis carousels face limitations in quickly and simply adjusting to products of variable size, lacking modular and centralized adjustment capabilities, and are constructively complex, making them less economical and difficult to set up for different rotation directions and unloading orientations.
Innovation Solution
The packaging machine features modular seats with adjustable longitudinal and transverse walls, utilizing a system of interconnected pinions and screws for precise and rapid adjustment, allowing for easy adaptation to varying product sizes and orientations, and enabling clockwise or anticlockwise rotation with flexible unloading options.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If complex adjustment mechanisms (secondary carousels, telescopic arms, rack and pinion) are used to adapt seats to variable product sizes, then adaptability is improved, but device complexity increases
Solution Approach 1:
The seat is divided into independent adjustable components: longitudinal walls with adjustable spacing and transverse walls with adjustable positioning. Each component can be independently adjusted using simple mechanisms rather than complex integrated systems, allowing modular adaptation to different product sizes without requiring secondary carousels or telescopic arms.
Solution Approach 2:
Instead of using complex mechanisms to move entire seat assemblies or secondary carousels to adjust dimensions, the invention inverts the approach by using simple, direct adjustment mechanisms for each wall component. The transverse walls are directly adjustable on the carousel table rather than being moved through complex linkages, simplifying the overall device while maintaining adaptability.
2Ease of operation
If centralized adjustment systems are implemented for carousel seats, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The adjustment mechanisms are designed with universal characteristics that allow the same simple principles to be applied across all seat components. The longitudinal and transverse walls use similar adjustable mechanisms, creating a standardized system that is easy to operate consistently across different positions without requiring complex centralized control systems.
3Ease of manufacture
If modular seat designs are used for economic production, then ease of manufacture is improved, but manufacturing precision requirements increase
Solution Approach 1:
The seat design incorporates dynamic adjustment capabilities that allow post-manufacturing adaptation to different product sizes. Rather than requiring high precision manufacturing of fixed-dimension seats, the modular components can be easily adjusted during operation to accommodate various product dimensions, reducing manufacturing precision requirements while maintaining operational flexibility.

AI summary
A packaging machine with a carousel with horizontal axes, particularly suitable for packaging rolls of paper or packs of paper serviettes or other solid products of variable size, of the type that comprises a plurality of identical seats on the same carousel, angularly equidistant from each other, radially open towards both the outside and the inside and each formed by a longitudinal wall fastened perpendicularly to said carousel and by a parallel and opposite wall, the distance of which from said fixed longitudinal wall can be adjusted to ensure that, with a movement parallel to the axis of the carousel, a product of variable size with its wrapping sheet can be inserted between these walls, and wherein the same seats comprise, between said longitudinal walls, two transverse walls designed to cooperate with the ends of said product with the wrapping sheet inserted in the same seats, which for this must have an adjustable reciprocal distance, whereby at least one of these transverse walls is connected to means for adjusting the distance from the other transverse wall, characterized in that said adjustment means comprise, for each said wall, respective internal threads and respective slides sliding on respective rectilinear guide means, directly or indirectly supported by the table of the carousel and parallel to the movement of the associated walls, with two sets of screws being provided parallel to these guide means that cooperate with said internal threads, which are also rotationally supported, directly or indirectly, by said table, these screws being kinematically connected to each other by associated means to ensure that by acting on one of the components of these connection means, the adjustment of the dimensions in length and in width of all the seats is performed in a centralized, rapid and precise manner to adapt them to the different sizes of the products to be packaged.
