Good morning to all colleagues.
I am not very experienced in tapes (or is it said carpets?) of transport, and I find myself to draw one that, without special attention, they tell me will not stand on track.
If someone has experience, even some simple advice would help me a lot.
Thank you.
I describe the monster.

must transfer bulk food, from oven, rather friable, from a tape to another tape. both tapes have rollers of diameter large, 150 and 240 mm diameter. their centers are 500 mm. mat widths : upstream 850 mm and downstream 820 mm. that downstream has also containment edges. the minimum speed is 2 m/min and the maximum 4 m/min.
1. therefore need a pen on the entrance side and a pen on the exit side, not to present a step too high to climb (inlet side) or to descend (outside side). the distance between the ends of the pens is about 460 mm; These pens should be stripped, with a 2.5 mm radius, for a thickness of 5 mm of the material (inox) of which the pen is made. the mat (or ribbon? mah?) should be 794mm wide and its development should be on 1100mm.
 
Hi.
in addition to the design of the structure you will have to provide all the material including conveyor belt, any guides?
I think you should contact some specialized company in the industry, especially considering that you are in the food sector and the product you need to install must comply with the different regulations.
the partner company of the one where I work (which produces transmission belts, even in the fda field) is one of the leaders in the field of conveyor belts (and all accessories) with a division for the food sector. I don't know if by forum policy I can put the company link in clear.
there are however several important and serious producers you can address
 
I agree with stefano gs... besides to make one only the game is not worth the candle.
with tapes so wide often it is necessary to use a central guide, or you could use tapes made of acetalic resin that have lasted much more, I don't know if you find that width though.
 
hello then we are talking about a tape 800 wide and interasse between the reels about 550.
I would definitely go on a monolithic tape, the modular ones when dirty do not clean them anymore and have pens of 8 mm approximately to the maximum.
the difficulty you will have will certainly make it go straight, mostly considering that it is wider than long. sure that after having struggled to make it go straight to the company from you after transport will go all wrong again.
my advice is if the boundary conditions allow it to be made to some company that produces stainless steel conveyor belts for food uses. Trust me that it will eventually cost you less and you will save a lot of bitches.
more than other dimensions have the pieces to carry? is it really necessary to have such a pronounced pen?
 
Frankly it does not seem to me in the spirit of this forum bypassing technical questions, which can affect many users, suggesting to buy the tape already made. without anything to remove to the exceptional ammeraal products, which I know and use too.
the argument is not trivial, given the particular width/length, the need for such a large pen etc., although max2 does 10 times before buying it done, it could be interesting to talk here about how to do it, since it is a site of designers, not of employees of the shop office. But maybe I'm wrong.
 
suggest the names of possible companies that already do these products, also serve to go on the sites to get acquainted and broaden their mental horizons, without necessarily simply asking for an offer to the commercial office.

It's very common practice in U.S. to decide whether to buy something already done or design it at home.
I think that those who opened the discussion need more practical advice than general discussion.
 
to try to generalize a little the speech for the speech fda you have to take into account:
- layout (curves, possible differences) that together with other factors directs the choice of tape (modular / integral with or without cables)
- material to be transported, this contributes to the choice of tape and significantly determines the grip that the tape must have
- washing cycles, temperature and detergents to select compatible material
- favorite color. In general, blue is considered the color that gives the most colour contrast with most products (according to the colour of the single product transported and the user's choices propose other colors). the blue is, however, the color of food transport

in this case given the width of the tape in my opinion if possible I would opt for a positive ingracing tape with 2 (better 4) guides.
also the choice of sprockets must be compatible with the hygienic conditions required
 
but with pens so bad we talk about diameter 5 mm a ribbon ingrazing positive can not use it, you have to go on a monolithic.
would be to be evaluated if it were possible to use larger pens and at the most use a sheet to cover the advancement but depends on the size of the pieces to be transported.
 
with pens is meant when the input or output rollers of a conveyor belt are very low, they are used to avoid having a hole between 2 conveyor belts
 
Hi, Teseo. Imagine having to pass objects from a tape with head rollers diameter 40 mm to another with tail roller from 30. leaving in the middle 5 mm of space + 2 thicknesses of the tape itself, say another 2,5 + 2.5 mm in total you would have 45 mm between the two tangenza points of the tapes with their respective reels. too many to pass without falling "to face" an object with a base, e.g., of 60 mm according to the direction of march. tapes capable of turning around very small diameters (usually they are very thin carpet tapes, with the inner side at low friction). As for widths such as the one that serves max2 a 20 mm roller, e.g., it would be flexible, it would be used 'ste pens', i.e. plastic or metal plates with a radiated edge adequately. the tape obviously does not turn on the pen, but it rubs on it and this involves a series of limitations that you can easily imagine.
some well made feathers are composed of a series of small diameter but rather short, coaxial rollers, each supported at the ends and flanked one at the other until reaching the width of the desired tape. they are not easy to realize because being small they turn fast also for relatively low tape speed.
here then we talk about 2.5 mm radius on width 800....of course there is no modular tape that turns on r 2.5: the smallest I know have step 12.5 and imagined how they would turn on... a edge. so by nasto force to carpet in canvas and also he, with width 800, to send it straight comes to me laugh. :
If then the rollers are 550 according to me it doesn't work without stretching it and making it do a bit of "empty spins" at the bottom of the conveyor structure, to get to a decent length, which allows you not to have too much wear, to be correctly reached by those who have to realize it (if you give them with the branch off squad you can throw them without even trying them) and that can also wrap around a roll proportional motor. It is clear that the speed and weight of what you have to carry have a fundamental role in choosing.
all this to say that 'the pens are not so simple.



Thank you, hunter, I had already understood from the reply of pietro 2002 that I was wrong. I have been deceived by the title of the discussion: designe...etc.
 
In fact, the positive ingrain belts have a minimum diameter of wrapping around 45mm.
another trick that can sometimes be applied is to make the inclined conveyor by starting it under the end of the first tape and finishing over the beginning of the third. the product in this case falls from a tape on the next. this obviously is not always said to be an acceptable thing both for the risk of ruining the product and for positioning accuracy
 
rereading the first post, the two current tapes have diameter 240 and 150 to 500 interasses. max2 would like to have the bridge with 460 pen tapes, so if the three tapes followed all the same upper wire, the bridge would come about 20 mm from the vertical of the roller axis,(I say about about because roll 150 leaves a little more space for the pens than the larger roller) is dimensionally impossible with "human" pens, for this reason he spoke of r 2,5, but not enough the same because the tape should turn 180° around the pen not to interfere with the rollers, but no manufacturer recommends this execution. the sweet products of max 2 will have to accept to jump a nice step to get off the bridge, but I don't understand how it can do to climb up there, unless they are donuts arranged so you can roll....:) the famous rolling donuts!
 
but beyond the donkey back rollers and blasphemies there are other ways to make tapes straight?:roflmao:
 
certain bm, on a line of food products is not impossible: just have a fixed technician all day running on the tape curtains and putting it straight on. you can feed on the products themselves that pass on the tape and just give it a little water 3-4 times a day.
 
By carefully reading everything, we are talking about something that is technically a very strong difficulty in the small size of the pens, important widths and reduced length.
I have taken care of in the past of transporting objects and sincerely in such a case I would not risk minimally using a miniaturized transpire tape but I would mount a vibrating platform, that is a linear feeder.Screenshot_20190907_195909_com.android.chrome.webpeventually you can use a linear vibrating base, type automations, with adjustable counterweight and vibration control box, with the possible addition of the probe to manage more or less load.
we mount a channel made by a floor with edge more front panels possibly built by full.
you give yourself some extra crossbow to see if you need to change the vibration stiffness and mountains all on a tilted base 1 about forward.
surely carry the biscuits to all beer without breaking them and the plan can have thickness even 2 mm in the connection zone towards the reels.
