Bobbin Transporting System (BTS)

The Bobbin transport system provides economic advantage to package handling of Ring Spinning. It ensures the protection of roving wound around the Bobbin, which is highly liable to damages during manual transportation. BTS also protects the yarn quality where the Roving defects are transferred. Bobbin Transport System is certainly the area in Spinning Mill where the investment in automation is more easily justified due to labour savings and reduction in yarn faults. Especially in the coarser count spun the labour saving will be higher.

BTS Advantages

  • Can be installed in the existing layout (both Building and Machinery)
  • Interface any speed frame and ring frame
  • Contact less Bobbin transport
  • No Mix-up of yarn counts
  • Technology upgradation
  • Man power reduction

Types

1) Manual Bobbin Handling System

bts1The overhead rails supplied to the ring frame for transportation of roving bobbins is extended by 3 meters. The doffed full bobbins are loaded in a trolly and brought to alley. The empty bobbin rail from the ring frame is moved manually to this ally where the empty roving bobbins are replaced with fully roving bobbins. Again the train with full bobbins is moved manually to the ring frame. This is a very simple and limited purpose option.

2) Manual Bobbin Transport System

bts2The Over head railings will be looped between all Spinning frames and all Speed frames group as in the enclosed drawing . In these railings , endless train will be always running at slow speed. Trains will be driven by motors fixed at frequent intervals throughout the railing .Trains will have bobbin holders with required pitch (according to Full bobbin dia).

Over head Rails are made of Aluminium and the trains are also made of Aluminium and anodized for smooth finish and corrosion free. Trains will be moved by Motors fixed at frequent intervals using friction wheel which has a smooth surface to prevent jumping of the drive. Main and guide rollers are made of Acetate – plastic with high precision bearings. The connecting tube design allows exact tangential traveling of train to have minimum wear.

Empty tubes and full bobbins are manually loaded on to the trains running in the over head railing in ring frame and speed frames randomly / whenever required as shown in the picture. Like this, whenever full bobbins and empties required, it will be removed manually from the trains running in the over head railing.

3) Automatic Motorized Bobbin Transport System

bts3The Over head railings will be looped between all Spinning frames and all Speed frames group as in the enclosed drawing . In these railings, endless train will be always running at slow speed. Trains will be driven by motors fixed at frequent intervals throughout the railing. Trains will have bobbin holders with required pitch (according to Full bobbin dia).

Over head Rails are made of Aluminium and the trains are also made of Aluminium and anodized for smooth finish and corrosion free. Trains will be moved by Motors fixed at frequent intervals using friction wheel which has a smooth surface to prevent jumping of the drive.

Main and guide rollers are made of Acetate – plastic with high precision bearings. The connecting tube design allows exact tangential traveling of train to have minimum wear. Empty tubes and full bobbins are manually loaded on to the trains running in the overhead railing in ring frame and speed frames randomly / whenever required as shown in the picture.

Like this, whenever full bobbins and empties required, it will be removed manually from the trains running in the over head railing.

4) Fully Automatic Bobbin Transport System

bts4In Bobbin Transporting System, Speed frames and Ring frames will be Connected by Over head rails ( through Buffer Area ) in which Trains will move as shown in the picture. Each train will have bobbin holders approximately half of the no of spindles in Speed frames.

Over head Rails are made of Aluminium and the trains are also made of Aluminium and anodized for smooth finish and corrosion free. Trains will be moved by Motors fixed at frequent intervals using friction wheel which has a smooth surface to prevent jumping of the drive.

Main and guide rollers are made of Acetate – plastic with high precision bearings . The connecting tube design allows exact tangential traveling of train to have minimum wear. In Buffer Area , there will be no of reserve tracks ( based on the no of Speed Frames Connected ) in which reserve bobbins will be stocked.

Before taking the doff in Speed frame, doffer has to call the train holding empty tubes to the particular speed frame rail from Reserve area by operating IN Switch provided in the Speed frame . Trains will be automatically moved to the particular Speed frame . He has to take empties from the train . After the doff , has to load full bobbins manually to the train as shown in the above picture and has to send full loaded train to buffer area by Operating OUT Switch.

Full bobbin trains will be stocked in the buffer area rails. Whenever full bobbins required in Ring frame , particular ring frame sider has to call full bobbin train from buffer area to the particular ring frame side by operating IN switch provided in each side of the ring frame . Train will be automatically moved to the particular ring frame side. Manually , has to remove full bobbins from the train , to load full bobbins in ring frame creel , also to load empty bobbin ( taken from ring frame creel ) in the train and to send empty bobbin train to buffer area by operating OUT switch.

This completes cycle. All the track diversion operation, rail allocation, selection and groupings will be controlled by PLC and can be changed time to time according to count change.
