About this deal

The functioning of a card feeder is different, the cards are placed on conveyor rubber belt and there is a funnel mainly composed of a curvy shaped parts. Sometimes there is a second double rubber belt conveyor to help the card to be grab. You can see the functioning in video here, and watch a patent below : So, what to remember about this ? That working with lego on some project is exciting and always fresh and new, but sometime also that the lego was not suitable for machine with high specs and needs. Personally, it is not the first project which fails for company but it has always something to learn about it. Here is the play on lego parts, especially when you build it virtually with Ldcad, you can not verify the exact functioning, always based on mechanical principle. That is why it is important to know your project, know how you will do, and especially build a prototype as closed as the final machine to have a global view of the project.

Note there are not picture for this section, you can see the different prototype in video section. Please read carefully the article and links attached to it, before post a comment / idea on this article. That is why I develop the last prototype which was inspire by automatic card feeder instead of card dispenser. The industrial card dispenser has the same function, which is a main roller and moving platform to grab the card and expulse it, it works fine because the rubber wheel have many friction and the whole assembly is very rigid and precisely set up (see here how a card dispenser works) Electronic : market (Nema Step Motor, blue tiny 9G servo, Rasberry Camera, wire and software by the customer) – 3D printed parts for attaching the elements to lego To qualify for a return of merchandise, you must follow the return guidelines set forth in this document and request a return within 30 days from the invoice date for this policy to apply. For a return to be accepted, all of the following must be included: Therefore, I kept the good idea of rotating drum but transformed it with a linear conveyor with many trays attached to the conveyor. After the card is scanned and placed in a tray, the second card comes to the second tray and etc; and when the first card is face of the correct bin, it is pushed out by a rotating beam on the tray. With that solution, the flow of card is in only way, each 1-2s a card is placed in a tray and other card in same time are push out in the correct bin. It had the huge advantage to by simple, with a number of bin extendable and with scanning and pushing out at the same time. The cycle time was only function of the scanning time and moving time for one tray.Custom made products such as hot-stamped folders or engraved nameplates are not eligible for return.

The story of a commissioned project that I tried to make, but failed. Here is the whole story of the development and why it was not a success. Second idea was to use the same principle with the card dispenser and camera, and use a moving drum which can rotate to take each card in tray and pushes the card in front of the correct bin. Therefore the output bin has to be placed in round of the drum. I started to build this version but it was to difficult to obtain correct shape and adjustment of the 10 bins, plus that at final it was not easily upgreadable in term of number of bins. After searching for idea, testing them and developing solutions, I had to recognize that, lego was not the correct solutions to do this, according to the project and the specs. This article explains why it had not work, and present the solutions I designed. This is not the first commissioned project, but the first since the Stage Trailer that I can talk about, so enjoy !
