Rotary Unit for Vertical Capsule Insertion in Flat Blank Boxes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current boxing machines are inefficient and bulky, particularly when trying to simultaneously insert multiple single-dose capsules into boxes, and often require pre-glued blanks, which are less economical than flat blanks.
Innovation Solution
A rotary unit with multiple receiving seats and stations for folding, inserting, and gluing flat blanks to form boxes, allowing for the efficient insertion and packaging of single-dose capsules using a series of synchronized stations that rotate and position the blanks to facilitate easy filling and closure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If horizontal boxing machines are used to insert capsules into boxes, then the insertion can be performed, but the machines become very long and bulky
Solution Approach 1:
The patent transitions from horizontal capsule insertion to vertical insertion. The box is positioned vertically on the conveyor belt, and capsules are inserted from above through a vertical insertion station. This dimensional change allows the machine to be more compact while maintaining insertion functionality, as the vertical direction utilizes unused space above the conveyor belt rather than extending the machine horizontally.
Solution Approach 2:
The boxing machine is divided into distinct functional stations: a conveying station for moving boxes, a folding station for forming boxes from blanks, an insertion station for vertical capsule insertion, and a closing station for sealing boxes. This segmentation allows each station to be optimized independently and enables the machine to perform multiple operations in sequence without requiring excessive length.
2Ease of manufacture
If pre-glued blanks are used for box formation, then box formation is simplified, but material costs increase
Solution Approach 1:
The folding station performs preliminary actions to prepare the flat blank for box formation. The blank is fed into the folding station where flaps are folded and positioned in preparation for capsule insertion. This preliminary folding without pre-gluing allows the blank to be easily manipulated and repositioned during the boxing process, and enables the use of more economical flat blanks instead of expensive pre-glued blanks.
3Volume of moving object
If vertical machines are used for capsule insertion, then the machine size is reduced, but control of vertically arranged capsule stacks becomes difficult
Solution Approach 1:
Instead of arranging capsules in vertical stacks and attempting to control them, the patent inverts the approach: boxes are arranged vertically on the conveyor belt, and capsules are inserted individually into each box from above. This inversion transforms the control problem from managing vertical capsule stacks to managing vertical box positions, which is easier to control through the conveyor system.
