[MOC] Rope Braiding Machine
Hugolin posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Hello. New post in this new year to show you this: So what connection between this rope and Lego, you say? The machine that does it, of course !!! I start with the video. Edit : WIP vidéo : Now, photos and explanation. This braiding is based on the following system: to alternatively turn the trays. Although it uses 12 strands, braiding is relatively simple: The strands are braided in fact four by four. The blue plaques turn to the right and red on the left, etc .. Between each rotation, the trays are realigned by "jaws". To power, a motor M is more than enough. The lever to switch to manual. Here, the manufacture of the central party of the rope: This part can be replaced: Here two little winding mécanisme for the bobbin: A very important detail: the elastics that ensure proper tightening of the braid. Finally, different braids made by the machine: And also Happy New Year ! -

Do you want to do ropes ? I have a solution ! I want to precise this braiding is not 100% reliable. Sometimes, a coil can block the machine. After the first prototype, I done a lot of modifications to have the best reliability, but I have not so mutch experience with this type of MOCs, and a V2 is necessary to upgrade this creation. There is a clutch to stop this machine if it is blocked. The objective was to do a braiding machine having a continuous operation, and to have a not too low speed. I had not objective concerning the number of strings. There are 8 strings + 1 central. I also really wanted a buttom to be drawn to start te machine and down to stop it. How does it work ? You can separate this machine in 3 parts : The braided wire winder The rotation of the trays The movement of the arms moving the coils You can have more tight braids by changing a gear ratio of the winder. But they are less beautiful. The rotation of the trays occupies the top of the machine. (The 24t that you can see can be easily used to coordinate the arms and the trays) Here you can see the mechanism of the arms : The linear clutch stops the machine if a coil blocks it. More picture here : http://www.techlug.f...43.html#p179043 The difficulty was to coordinate all the mechanisms and to counter stress and flexion of the parts for the machine can work without too much fails. Finally, the machine can be locked because of a coil, but I’m satisfied because it works correctly and the braids are very regular. I’ll done other MOCs of this type because I like it ! The video will show you the operation :
