I got hundreds of comments on my last video encouraging me to build a sorting machine to sort the marbles of my marble clock. Fair enough, I built one. Now the question is, should I put this in the clock to sort the marbles while the clock is working or should I make a different sorter for the clock. This one is super loud, which seems to be on brand with my clock designs, and seems fast enough to be used with the clock in realtime. I would obviously polish the design to make it nicer but you tell me. What should I do?

  • I design high speed industrial control for work and I'd like to share a few suggestions You could use pulse compressed air to push the marble out of the belt. It can operate way faster and will not create a physical barrier that collide with the belt. Also the trigger solenoid can be directly connected to the infrared sensor so you sort the marble while they are being evaluated (direct connection without logic will work fine). Last, using a ramp and gravity would also simplify your setup. The only electronic would be for detecting/sorting (speed may need to be tested though). I designed several high speed sorting systems (1000+ items/s) for all type of products, and using sensor directly coupled to the actuator (pneumatic) is always the most reliable and fastest solution.

    • I think that he is using an IR proximity sensor, which looks like the ones designed for use with Arduino or other microcontrollers boards. As far as I know you can't directly connect a sensor like that to an actuator because the analog value representing the sensor's light level has to be evaluated somehow to trigger a control output. This is all just speculation though.

    • @@SpaghettiEnterprises You are most likely correct. Another type of sensor would need to be used. Something a bit more industrial where you can set a level of detection and provides a dry contact where you can use whatever voltage you want (typically 24V). They are a bit more pricey ($100 - $200), but they are reliable and no logic needed. Also the solenoid for the compressed air would need to be a pulse type, basically provide a pulse of air on a rising or falling edge. That way even if the detection last a long time, only a single pulse would be provided. Industrial world has all these use case covered ;) But it takes $$$. Hobby electronic is cheap but take time time time....

  • I know this would be a _lot_ of work on top of what you've already done, but what about building a second sorting machine? You don't even have to change the design, just have a second sorter running in parallel with the first. That would allow you to reduce the speed (maybe to only 15 marbles / s?) and still be able to sort _really_ quickly, since you're effectively multiplying that rate by 2.

    • I'd say stick with like 10 marbles/sec. It was around that point that the solenoid was actually consistent in getting every black marble out from the shiny ones. The machine only needs 17 marbles/sec, with two sorters at 10 marbles/sec that gives you 20 marbles/sec, more than enough.

  • Two ideas for possible improvements: 1. Eliminate switching on empty slots. Either switch on the light marbles instead of switching on both dark marbles and empty slots. Or make the chain white and continue switching on black. 2. Make use of paralelism. Use more solenoids to kick multiple marbles at once. With two solenoids you can do odd and even slots. Etc.

    • Adding more solenoids doesn't really work cause the chain is moving constantly and the solenoid reached the limit and having the chain move any faster means it can't punch out and retract within the time a single link passes by meaning it'll interfere with other marbles. More solenoids won't change that. Instead you'd have to duplicate the entire mechanism

  • I think the main issue is using something that goes forward AND backward to kick the black marbles off. It would be easier to have a gear shaped object over the conveyor. The marbles pass through the valley between two teeth when they're silver, and the gear rotates by 1 tooth if a black one needs to be kicked out. That way you only have to move in one direction, instead of moving to kick the marble out, and then retracting it. This gear could be tight to the track, so with teeth on either side pretty close, but that would probably result in acceleration issues, so you could also have a very wide gap between the teeth, so it has time to get up to speed. In theory, this solution would be able to kick off marbles at any speed, it would just require a larger gear wheel and larger motor.

This would add some work on your program, but would really help reduce speed you need to sort marbles, and 2 marbles wouldn't change anytime. Of course it wouldn't be that spectacular.

  • some ducting and shroud work and it should work well. also, mount the whole machine in a tub that will catch all the marbles that "escape" and return them to the unsorted hopper for reprocessing. in fact, when the marbles get released from the display let them fall into the tub right away for resorting. and if you use ping-pong balls the noise will be much reduced. OK, the display will be BIG but that is ideal for a makers fair or a shopping mall.

  • This would put on quite a show with two lifts rejecting opposite marbles and sending them down a slide or tube. It also means you can get away with not pushing everything so hard - if you need 17 per second, you can have both lifts run at 12 per second and be well beyond the required speed. You then also get the wonderful aesthetic of watching silver marbles go down one tube/slope and black marbles go down the other tube/slope, and two buckets at the top which also could maybe also have a tube/slope that terminates in its destination splitter at the back of the clock.

    • Another idea for pushing the marbles out, could be to use a servo motor for that too, and a wheel with openings in. That way it only needs to rotate enough to push the marble out, and move a new hole into position. Depending on the diameter of the wheel, it would only need to rotate a few degrees, and at the same same movement move the next slot in the disk into position, ready for the next marble. To make it very reliable, you could have a look at the stepper motors with driver and encoder build in too. I have been playing around with some, and they have been very reliable and VERY fast in acceleration and deacceleration, and even if it is missing some steps, it will correct it immediately.

    • I think you could definitely program out the dry firing, he probably just went with a quick and dirty "if sensor is less than setpoint, eject marble". There's almost definitely some difference between readings from the black marbles and the chain, you would just have to add another case to the decision logic. Or you could just print the chain in something that's not black. A can of white spray paint might also do the trick.

    • I think the reason he's doing it that way is for the visual effect. Right now the matrix has a total of 3x5=15 cells, each needing to be updated every second, as well as a ten's place that needs to be updated once every ten seconds. The minutes/hours add ~.28 balls/second for a total of around 16.78 balls a second. If you only replace marbles that change between digits, you'll need on average 5 balls per update for the one's digit, and 5.1 for the ten's place. Accounting again for the minutes/hours, this leaves your total consumption at around 5.7 marbles/second. Definitely more manageable, but I believe his goal is overall impact, and more marbles means more noise, more movement, and more impressive mechanics.

  • Instead of the solenoid pushing the marbles directly, wouldn't a sprocket gear make more sense? So that you only have the time of the gear moving through the chain once, without it having to get BACK (like the solenoid has to) to clear the way of the chain Alternatively, you could just go for pressured air, which is how sorting is done in recycling centers. It would also save you the timing of any backstroke and would have the additional advantage of not having to break mass like you do with the solenoid prong, which also causes noise and uses energy (=heat)

    • I think the major downside of pressurized air is the noise from the compressor. They're very loud, and not the charming click-clack of marbles being shuttled around, but a deep growl. Compressors also tend to be bulky, making them hard to integrate into designs. Both of these issues make them decidedly not maker-faire/youtube video friendly. I'm also not sure Ivan is particularly familiar with compressed air, and incorporating into a large scale project like this may be more work than it's worth.

  • i haven't read any comments yet, so i have no idea if this was mentioned before: in the industry, they use air pressure to separate good from the bad (and the ugly, if necessary). it has the advantage of not having any moving parts (except the valve, of course), and therefore it is much faster and less prone to failure...

  • If the solenoid actuates a fork at the end of the chain, you don't have to worry about it getting caught in the chain. Also, you don't need a chain anymore, because you can just let gravity make the marbles fall through a funnel and put the fork at its exit.

  • 1. Make the marble's impact point higher than the tooth of the chain (to prevent the chain from jamming and causing destruction). 2. Create a wheel resembling a fan (with 4 wings) that rotates 1/4 turn each time marbles need to be moved. This will ensure a smooth motion (unlike back and forth motion like a piston, saving half the time). 3. Design a larger cover for the inner bucket. 4. Form a funnel shape to catch the outgoing marbles.

Still, glad to see my advice taken!

  • Of course you should incorporate it! You'll need a steady supply of sorted marbles. :) Two suggestions: - switch from the solenoid rejecting black to rejecting while/silver. Then it won't trigger on empty slots. Less runtime + heat. - mirror the design to run two chains rejecting marbles into a central bucket. Then you can run it a little bit slower, have more room for error, and throw less marbles around at the loading end of the chain(s).

  • Ideas on how to optimize the sorter: 1. Make 2 rows on a chain drive. The left row is for light ones, the right one is for dark ones. The solenoid above the left row throws dark balls to the side, and above the right row, vice versa. As a result, dark balls will fall on the left, light balls on the front-left, dark balls on the front-right, and light balls on the right. You just need something like a tunnel to direct the side balls into the corresponding basket, and you will get a 2x acceleration - that is, you can slow down the conveyor and it will become quieter. 2. Why a conveyor chain belt at all? Raising the balls up is extra work, you will still have to raise them later to the level of the number dialing mechanism. Let there be just something like a gear wheel inside the corner of the diamond-shaped container, where instead of teeth there are seats for balls, on the sides of it there are 2 containers for already sorted balls, and above it there are 2 solenoids for resetting to the left or right. Fewer moving plastic parts = less noise and greater reliability.

  • Couple potential ideas.... Elecromagnets to yank the marble out. Air to shove it. Create the belt with an opening in the middle/bottom, and poke it from below. Also, you likely already have a plan, but if you're making a full clock like this you're going to have six of these side by side, having gear hanging off the side is going to make that difficult, unless you make a bunch of longer fancy ramps to deliver marbles, but then you risk your stops at the end not working.. Your Marble Return ALSO has to manage at least 15mps as well (probably closer to 20 when you factor in the rest of the digits) Certainly an interesting technical challenge!

  • I think if you modified the chain a bit, you could avoid the solenoid crashing while still being able to carry the marbles, perhaps by trimming down the outer edges of the fins or reducing their height. Raising the solenoid up and moving it slightly farther away from the chain may also help, and mounting it on a spring loaded or flexible bracket could help with clearing and recovering from crashes. (who doesn't love 3D printed compliant mechanisms?) Another way you may be able to attain higher consistency would be to do something to tame the bouncing on retraction. A modification I would very much recommend if you choose to put this into the final clock would be a rubber tip for the solenoid, to avoid marring the finish on your black marbles.
