Sharing some project planning phase: A (digital) ELECTRO-MECHANICAL Network

<< < (18/39) > >>

RJHayward:
...so this photo shows the loop aspect, where, having position the 'A' switch, back to transparent mode, the output wheel / gear gets contacted and gears start acting to convey that 'overflow' signal.
That signal actually might not keep enough momentum as noted, the actual power source or rotation source has been switched away.
Purpose is to cut the accumulated resistance, in the network, by doing some tasks as 'one time only'.

RJHayward:
Ha ha, the photo looking like a Wedding Cake !
   This stack of switches gets the two, 'B', and 'C', to move together, when SEL signal comes.  First layer, starting at bottom, is so-named local 'Motor', just a lable for that bigger gear. It is called 'Motor' as it is what moves the whole toggle, first by dragging the little inter-gear, literally, due to the heavy dollup, of green goo (an industry term, likely).
   Likely, this kind of moving toggle, in the toy, can't be used at very high speeds.  At 1100 rpm (18 rev per sec.) the toy had two gears to divide down to about 2 rev per sec. before applied to the special intra-gear path switch.
   First layer does position of toggle, (that whole, towering mess...) while the middle layer is 'C' channel.
At top, you can see the layer for doing the 'B' switch.

I've left out a lot, this diagram is probably too unrecognizably novel. Yeah, I get that, a lot, sometimes.   Up top of this; the 'A' segment has also a couple of layers. The 'A' switch channel is set together with 'B' and 'C' latching, but then will, actually be used later to reset 'B' and 'C' position.

RJHayward:
   This photo shows the toggle-gate used with 3 switched signals. The 'B' channel commutator is highlighted in green; that's the 'B' output gear in the back there. That's a 25 tooth, while those little inter-gears have 10 teeth.
Ironically, the lower 'switch' has no outputs as that is the positioner 'motor' layer.  The 'A' channel is shown attached, in this generic switch view, but actually is independent, having its own large positioning gear, like the one seen at the bottom of this stack of switches
Readers may have difficult following the explanation, for how to clear the 'A' portion of the 3 switches.
   When the 'B' channel starts using it's chain output that indicates that it's time to clear the 'A' side, and preferably only once.
That way the whole switch, at that station, has gone to transparent mode; merely passing signals through to next station.
   Some problems also with gear ratios, which need to stay near 1 to (almost) less than, say, 1 to 1.1.
When doing 'motor' internal, at a particular station, it's OK then, to have gear down, as it's not a situation that the ratio keeps growing, outragesly.

RJHayward:
   Photo shows, maybe hard to design, but to build is all standard stuff.  The solution, for three main problems, is each with two gears, perhaps just one in a case.
   Looking at 'green' output gear, that's tapped, with rotary action used to reset segment 'A', in the current box. See yellow gear; that's the gear to drive, (CW or clock-wise). That will put switch to 'transparent, pass-thru' mode.

RJHayward:
   A really fun thing, about this diagram: that yellow gear to blue gear rotation doesn't happen until, maybe 300-400 mSec. AFTER the blue gear starts getting driven. Sort of an overflow - saturation indicator.
Using that, so-called 'Cascade Overflow' makes it safe to start (trying) to disconnect from the source of rotary action. Should, hopefully, disconnect (perhaps another 600 mSec. ).
The full switching on the 'A' segment there, gets the transparent mode in place.
