We have small paper tubes 6mm id 7mm od - 50 mm length. we need to assemble the tubes in plastic cartridges as shown in the attached picture. The cartridge has two parts and when tubes are inserted in the one part and the other part of the cartridge is inserted, it looks like a strip as shown in the picture. There are 27 pins in the cartridge. 5 pins are little lengthier to ensure tight holding of the tubes. Design an automatic machine to fill automatically the plastic cartridges with tubes.About 10,000 strips are to be filled in a day. You have to ensure that damaged tubes are eliminated and all the pins are filled before next cartridge is passed on.
