Packaging Machine Vertical Tray Stacking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing packaging machines lack efficiency in automatically placing products, such as trays, into vertically stacked configurations within packaging articles like sleeves or cartons, especially when dealing with laterally offset and differently heighted conveyors, and fail to effectively guide and insert contents into pre-glued sleeves or cartons.
Innovation Solution
An automatic packaging machine with in-feed conveyors at different heights and lateral offset configurations, equipped with spacer arrangements and pushers to converge trays into a vertical stack, and a sleeving station that erects and inserts sleeves around the stacked trays, utilizing internal dividers to guide contents into apertures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple conveyors at different heights and lateral offsets are used to feed trays, then the productivity and automation of the packaging process is improved, but the device complexity increases due to the need for additional convergence means and alignment mechanisms
Solution Approach 1:
The in-feed system is divided into multiple independent conveyors operating at different heights and lateral offsets, each responsible for feeding trays from separate locations. This segmentation allows parallel operation and increased productivity while maintaining manageable complexity through modular design of each conveyor unit
Solution Approach 2:
Convergence means are introduced as intermediary elements between the multiple conveyors and the packaging article. These convergence mechanisms align and combine the trays from different conveyors into proper vertical stacking configuration, facilitating the transition from complex multi-conveyor input to simple vertical insertion into the sleeve
2Manufacturing precision
If spacer arrangements are used to maintain space between contents, then the manufacturing precision and alignment accuracy are improved, but the device complexity increases due to additional spacer components and adjustment mechanisms
Solution Approach 1:
The spacer arrangement is designed to self-adjust and self-maintain proper spacing between trays as they move through the convergence zone. The spacers automatically adapt to slight variations in tray dimensions and positions, providing consistent spacing without requiring complex active control mechanisms
Solution Approach 2:
Spacers are pre-positioned in the convergence means to establish the correct vertical spacing between trays before insertion into the packaging article. This preliminary spacing action ensures proper alignment and prevents the need for complex active adjustment mechanisms during the packaging operation
3Ease of operation
If internal dividers are used in packaging sleeves to guide contents, then the ease of operation and insertion speed are improved, but the manufacturing precision requirements increase due to the need for precise divider positioning and aperture alignment
Solution Approach 1:
Internal dividers act as intermediary guide elements within the packaging sleeve, providing physical guidance for tray insertion. These dividers create apertures that naturally guide trays into correct positions, facilitating rapid insertion while the convergence means handles the precision alignment of trays before they reach the sleeve
Solution Approach 2:
The packaging article is segmented into multiple compartments by internal dividers, creating distinct apertures for each tray position. This segmentation provides clear guidance for tray insertion while allowing the convergence means to handle precision alignment separately, reducing the overall precision requirements for any single component
