Bobbin Transport Semi Automatic System
Partly automated : Either Roving Area -> Storage Area (or) Storage Area -> Ring Spinning Area - Fixed connection/Flexible Connection
The bobbins are doffed by hand at the roving frames and hung up into the rail in front of them.
The operator pushes a button to drive the train to the storage area automatically.
The Storage is able to store the loaded trains and can be used for trains with full bobbins as well as for trains with empty tubes or un-cleaned tubes.
If a ring spinning machine needs full bobbins, a button at the ring - frame is pushed and the train with full bobbins are automatically driven to the ring spinning frame.
Inside the creel the train can be moved easily forward and backward manually to the place where full bobbins are automatically driven to the ring spinning frame.
Inside the creel the train can be moved easily forward and backward manually to the place where full bobbins are needed.
If all bobbins are changed, the train is driven back to the storage area automatically by pushing a button. While the train with un - cleaned tubes is waiting for the next doffing the tubes have to be cleaned manually.
After finishing the cleaning, the train can be released and called from the operator at the roving frame by pushing a button automatically.
A computer system controls via monitor drive motors as well as electric point switches and shows what happens in production.
So a Semi-Automatic system is very flexible and each roving frame can feed every ring spinning frame.
