pneumatic connection between "translating" rooms

[Dum]

already that you had the courage to open the discussion, despite the title, is why to thank you.
I would have refused.
But I didn't know how the hell to synthesize the "problem." :

then, let's start from the beginning.
for my client I am impelled in a beautiful application, but like all beautiful and simultaneous applications, it is a bitch.
or at least it is for my experience trunk.

I am designing a clamp with "double opening"; I have to step aside in the two diversions of mosaic tiles.
tiles should be taken from different tracks of a vibrator and placed on a tray.
If in every single track the tiles are in contact and I have to bring them to 1.6mm of light, in the sense of the slopes I have to start from a 60mm interasse and bring them to light 1.6mm.
I hope he managed to explain to me (and if I did, congratulations again, I did not understand).

mosaic tiles are held by n suction cups (250) and are clearly fed. having big problems of space, you are talking that every suction cup, support, cart must stay in a lesser area of 30x30

I had this "fantastic" idea.
a single feed on the first block and the other suction cups mounted on blocks that on the one hand have a hole and on the other side a "pin" that fits into the hole of the next block.
all closed with a cylinder seal.

I hope that after I'm pippone, a photo of the application can help.
I have tried to look for long and wide between the suppliers of triggers if there is something that could help me, but for two days I am going through online catalogs and I begin to have the doubt that, unfortunately, there is nothing "ready"

Having to make 250 blocks of this kind between tolerances and workings would cost a spropository, not to mention that for a cycle every 4 seconds on the 3 shifts the possibility that within 6 months the seal is not something to take into account.

do you have experience of commercials that could help me save money to my client?
(or a smarter idea, that's fine

Thanks to anyone who wants to waste some time. .

so you have a matrix for which initially the tiles are spaced of 0 in x and 60 in y, and eventually you have to put them to 1.6 in x and 1.6 in y, right?
If it was just a line you could have used an articulated parallelogram to connect the various suction cups and then drift the bike to all the others, so sincerely I don't know, I should think about it a bit.

You could also use springs that detach the blocks by bringing them to 60 mm, and then with only one cylinder "stringi" the package in the opposite direction to the springs until the gap between each cart to 1,6, but it is very difficult to imagine a spring with a similar excursion.

Hello hunter, thank you for the time spent.
yes, the principle is correct.

but "presumably" the opening/closing system I have done it and I am confident that it works (if anyone interested I can show it and explain it) my problem is that on x I would like to create a single "empty chamber" in order to have to manage only 19 pneumatic feeds and not nearly 250.
from here the need to be able to connect the various blocks in order to manage the race.
as mentioned before, the initial idea was to model each block with a hole and a pin so that the hole fits the pin of the previous block and the pin of the block falls with the hole of the block above all with a seal.
a system like that would cost a fucilage and go build 19 identical blocks to set up all coaxial. .
risk eating my estate after 2 months. .
the request aimed to understand if there is any type of pneumatic connection that allows an axial movement between male and female. .
I know it's not immediate for how I explain..

I see from your image that there is a strong risk that the last suction in the row does not prevail as you thought you were doing the graft. how many files and columns do you have?
use classic rilsan tubes? Don't you have space?

 

[Dum]

hi brn, say I have 12 files, each consisting of 19 "blocks".
each row will have a dedicated power supply, the 19 blocks I would like to make them with a single power, also because once deposit, on the matrix both in x and in y ho 1.6 of light, and I have only one free side (in the head of the first blocks) to put the power supply

 

[Dum]

hunter, to make it short I started from the pantograph principle but I simplified it.
shooting with a cylinder the last block, on each block I put 2 thorns on which I put a "ring" (type mesh of chain but asolata) that limit me the run to 1.6.
pulling the first takes behind the whole series, with little more than 40mm running I open it.

same speech for 60/0 but with longer rings.

The jokes in 0 make them the bodies themselves of the blocks.

 

[brn]

Did you do a test to simulate the single row? I think the last ones are likely to kill little. and also evaluates the time to generate the vacuum seen the long room that connects the suction cups

 

[Dum]

No, I'm still totally theoretical.
We will use a blower, I don't think with the air volumes moving that there may be problems. .
but between thinking and making calculations passes..

If the race is 1.6 mm, I'd like to make some special seals that make it "top" in this way you don't become mad with mechanical couplings. It's a jumper thought of flying. think if instead of keeping radially as from the scheme you can work axially

You're right, I'm sorry, I answered a question you didn't....

Look. .
among the various delusions, before detaching I was trying a version that previews to the use of other bellows working between the faces of the blocks. .
It just seems a little daring on me. .
Tomorrow morning, I'm taking a picture of the idea I'm developing. .

 

[Dum]

You're right, I'm sorry, I answered a question you didn't....

but we miss you to apologize..

 

[Dum]

I know, nobody asked me. :
but I still place the development of the idea I anticipated above, using other suction cups as an element for the passage of the vacuum and at the same time compensate for the race.
chjiaramente, mechanically there is no possibility that the suction cup "loss" the surface, is always compressed.

processing costs should therefore be reduced. .

hi dum beautiful idea that of the sucker..... I have made several of these hands of grip, but never as large as number of suction cups, but always in narrow spaces.
I have always solved with a feed on each row or column of the matrix and passing
from one suction cup to the other, with this type of indent, thread m5 size of the picture 11/10mm, use spiraled tubes to measure,(I bought them from the metalwork today) or when can transparent smc tubes are hyper flexible.
I hope I've helped you.
a question I do not understand how you can do all that race with only 60mm, i.e. if I understood your mechanism well that then it was also my(oh at least I think), I would need a cylinder race equal to the number of suction cups to move to the race of every suction cup.....
