This depends somewhat on what is causing the cans to tip and how.
We've had the transition gap be too wide or too uneven, causing the cans to catch during the push and tip them over. This will happen over the course of time, and just requires some monitoring and adjusting of the heights of the conveyer and the seamer as they will drift apart over time (ours both have adjustable feet we can use to alter the height and a transfer plate between the two that we can adjust as well).
We've also had a smooth transition across the bottom of the can, but the sudden increase in speed the opposite direction would still knock them over somewhat regularly. We actually just cut some tubing and zip tied it to the edge of the conveyor rail to serve as a sort of bumper when they wobbly in the corner, and this has all but completely solved that issue.
Finally, it could be your can push heading into the seamer that is to blame. This is one of the most common adjustments I make when things start tipping too much on that transition. If the push is too hard it will knock it over on the transition, and if it's too soft it can cause that wobbling as the can edges on to the conveyer too slowly. Finding the right speed on the push can make all the difference.
