Optical Fibre Winder meeting #2 – Design introduction Dawid Patrzalek 17.06.2016

First machine concept First machine concept was assuming machine: Fully programmable (reeling speed, changeable pitch, etc.) Motor powered

First concept machine cost estimation Cost estimation of the mentioned machine: CERN – 78.5 kCHF Mechanics (materials and manufacturing) – 7.5 kCHF Control system (estimation provided by J. Lendaro): Material cost – 8 kCHF Production cost – 3 kCHF Control system development – 60 kCHF (at least 6 months of work for fellow) Mobac (German company) – 20 kCHF Showmark (USA company) – at least 20 kCHF + tax Final conclusion – we can not afford it!

New machine concept New concept assumes fully human powered machine:

New machine concept

New machine concept vs old one Despite significant change compare to the first conception, we still provide: Possibility to install variable spools Adjustable reeling pitch and width Accuracy +/- few mm Cutting machine integrated Fast and easy to use Upgradable Integrated display Possibility to reel certain length of the fibre 2 programs: Reeling program Measurement program Adjustable reeling speed Length measurement Anti-slipping detector Preload system New concept machine disadvantages: Not changeable pitch (it will be changing automatically) Sinusoidal speed of a pitch mechanism Every change of a spool size extort change of a crankshaft (to be explained)

Pitch calculations To be introduced with help of Excel file

Further steps to do Safety covers to be design and integrated Fasteners to be integrated Ceramic spools to be replaced by aluminum ones (???) 2D drawings to be done

CE marking Motor powered machine require CE marking Human powered machine do not require CE marking (only basic safety regulations have to be taken into account) Information provided by HSE

Schedule To be introduced with help of PDF file

Optical Fibre Winder meeting #1 - Preliminary design proposal Dawid Patrzalek 30.05.2016

Design requirements Mechanical requirements Possibility to install variable spools Adjustable reeling pitch and width Accuracy +/- few mm Cutting machine integrated Fast and easy to use Upgradable Control system requirements Integrated display Possibility to reel certain length of the fibre 2 programs: Reeling program Measurement program Adjustable reeling speed Length measurement method to be chosen Anti-slipping detecting method to be chosen Preload system??? (electro-magnetic brake)

Preliminary design – general description Source spool Target spool Cutting machine Drive system Rotation counting

Preliminary design – driving system Pitch motor Main drive motor

Preliminary design – variable spools installation Preload wheels Cone shape nuts

CE marking Is it mandatory in our case? An example of CE marked machine: http://www.showmarkcorp.com/product/unispooler/

Further steps to be done CE marking decision has to be taken Cost evaluation Schedule evaluation Control system proposal Final design proposal
