The biggest challenge<\/h2>\n\n\n\n
Synchronization of the lower and side belts.<\/p>\n\n\n\n

<\/figure>\n\n\n\nSolution<\/h2>\n\n\n\n
A twisted toothed belt transmission allows for the connection of two axes that are not in the same plane. The key is finding the correct positioning of the belt deflection rollers.<\/p>\n\n\n\n

The conveyor transports cartons, into which two robots insert cardboard absorbers. The cartons come in various lengths and widths.<\/p>\n\n\n\n

<\/figure>\n\n\n\nChallenge<\/h2>\n\n\n\n
For the robot to glue the absorber, the system must know the exact position of the cartons throughout the entire transport. For the adhesive to adhere, the absorber must be pressed against the carton wall, which can cause it to shift on the conveyor.<\/p>\n\n\n\n

<\/figure>\n\n\n\nSolution<\/h2>\n\n\n\n
Two side straps lightly compress the cardboard, providing adequate traction.<\/p>\n\n\n\n
Another challenge<\/h2>\n\n\n\n
Synchronization of the bottom and side straps.<\/p>\n\n\n\n
In the required configuration, it’s impossible to use off-the-shelf bevel gears. They simply don’t exist. A more complex, multi-element drivetrain would be required.<\/p>\n\n\n\n
The solution turned out to be a twisted toothed belt transmission, which connects two wheels with axles that are turned 90 degrees to each other, but not lying in one plane.<\/p>\n\n\n\n
