Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The manual filling of carton trays with leaflets is inefficient and labor-intensive, particularly for pharmaceutical products that require extensive instructions and warnings, often resulting in slow processing times.
Innovation Solution
An automated tray filling apparatus utilizing a robotic arm with a gripper to transfer leaflets from a stacking tray to carton trays, maintaining vertical orientation with a spring-loaded end stop and a stuffer to push leaflets into sleeves, operated by a computer controller, eliminating the need for human labor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual filling of carton trays is used, then operation simplicity is maintained, but productivity is low and labor intensity is high
Solution Approach 1:
The filling apparatus is divided into distinct functional modules: a robotic arm for picking leaflets from the stacking tray, a transfer mechanism for moving leaflets to carton trays, and an automated insertion system for placing leaflets into sleeves. Each module operates independently but coordinates through centralized control, enabling high-speed automated filling while maintaining manageable system complexity through modular design
Solution Approach 2:
A computer controller serves as the intermediary that coordinates between the robotic arm, transfer mechanism, and insertion system. The controller receives signals about leaflet availability and carton tray status, then orchestrates the sequence of picking, transferring, and inserting operations, enabling automated high-speed filling without requiring complex mechanical interconnections between components
2Extent of automation
If automated robotic filling is implemented, then productivity increases and labor is eliminated, but device complexity increases
Solution Approach 1:
The robotic arm is designed with a universal gripper that can handle multiple types of leaflets and packaging configurations. The same robotic system performs both picking from the stacking tray and placing into various carton tray configurations, reducing the need for multiple specialized robots and simplifying the overall automated system architecture
Solution Approach 2:
The apparatus incorporates self-aligning features where the leaflet stacking tray automatically maintains proper orientation, and the insertion mechanism self-adjusts to accommodate different leaflet batches. The spring-loaded end stop and vertical orientation maintenance features enable the system to self-correct minor positioning variations without complex sensing and adjustment mechanisms, reducing automation complexity
3Volume of moving object
If leaflets are stacked horizontally in stacking tray, then space utilization is improved, but maintaining vertical orientation during transfer becomes difficult
Solution Approach 1:
Leaflets are pre-stacked in horizontal layers within the stacking tray with alignment features that maintain their vertical orientation readiness. The robotic gripper is designed to engage with the top layer while preserving the vertical alignment of the stack, and the transfer mechanism includes guiding surfaces that maintain orientation during movement, ensuring precise vertical placement without requiring reorientation during transfer
Solution Approach 2:
The apparatus uses simple, replaceable alignment components such as spring-loaded end stops and guide plates that are easily adjusted or replaced. These disposable-like components maintain leaflet orientation through simple mechanical means rather than complex adjustable mechanisms, achieving precise orientation maintenance with minimal complexity

AI summary
Leaflets are stacked horizontally in a stacker tray after folding, with the leaflets themselves aligned in a vertical orientation. A tray transport platform supports a plurality of tray sleeves and a plurality of corresponding trays located adjacent to the stacker tray. The trays can slide into the tray sleeves as each tray is filled with leaflets. A robot gripper is adapted to be selectively placed inside the stacking tray. The gripper captures a batch of the leaflets as they are stacked, and places them in a selected tray. A sleeve holder is selectively placed in and removed from the selected tray to control entry of the leaflets into a corresponding tray sleeve, and a stuffer pushes each batch of leaflets inside of the sleeve. A controller operates the components of the apparatus so that the leaflets are transferred from the stacker machine to trays without human labor.
