PREFACEIn-Plant training has been misinterpreted by most of us, Industrial training, in a true sense, has been included in the curriculum to make the students well versed with the technical procedure of various industries and the basic criteria for management of resources in a company or industry. The educational institutions sole aim by industrial training is to improve the technical know-how and to have a hand on experience to make them realistic in thinking to understanding the procedure for manufacturing keeping in mind the minute detail which will benefit the customer. Like no learning is proper without implementation, similarly the terms and procedures we learn are of no use until and unless we bring them in practical applications. To summarize, industrial training teaches us industrial ethics, advance technical know-how and helps us to get acquainted with industrial working style.

Hindustan Coca-Cola Beverages Pvt. Ltd., Jaipur

Hindustan Coca-Cola Beverages Private Limited at Jaipur was started in late 1999. To be exact on 26th December 1999, with the production started with the RGB line, i.e. Return Glass Bottle Line. PET bottling plant was installed in the year 2003, where the PET bottles were formed and filled. Today both the lines are running successfully with an average production of 36000 thousand bottles per hour in RGB Line, i.e. with approximately capacity of 8,64,000 bottles in a single day. And with 7000-9000 PET bottles per hour, i.e. approximately capacity of 1,68,000 - 2,16,000 PET bottles according to different size variants, ranging from 600ml to 2.25 litres

RGB Line overviewThe RGB line deals with the filling of glass bottles of different shape & volumes. RGB stands for Return Glass Bottle. In this line empty glass bottles that are brought back from the market are refilled with fresh beverages. This line has very high production rate up to 600 BPM (bottles per minute) which results in the production of 36000 bottles per hour which is amongst the highest rate of production of finished goods in a manufacturing unit. In this line two key machines that are used is the bottle filler & crowning machine and the bottles washer. The dirty bottles are cleaned using the bottles washer that removes all dirt & germs form the bottles and then the bottles are filled & crowned by the bottle filler & crowning machine. This production line is a fully automated line in which the bottles move on a moving conveyor line, this provides high work standard & quality to the product.

Functioning of RGB line1. Bottles to be filled are loaded on the conveyor in crates for filling manually. A worker transfers the crates one by one to the conveyor from the stack of crates. 2. A water jet cleans the bottles in the crates, this removes some of the dust & other unwanted materials form the bottles in the crates. 3. The bottles are now transferred from the crates to the conveyor by encase. The encaser picks up 96 bottles in one go i.e. it picks up bottles from four crates in one go that is a total of 96 bottles. 4. The bottles are inspected manually for bottles of different brands than the once that are under production. The unwanted once are removed. 5. The bottles are washed in a 6-phase bottles washer. The bottles washer cleans the bottles using hot water and a number of chemical cleaning agents. It mainly uses hot water & caustic for cleaning the bottles. This machine uses moving pockets for taking the dirty bottles into it for cleaning & putting the cleaned bottles back to the conveyor. It has groups of 40 pockets lined together in which the bottles are kept such that their neck is on the inside of the neck. The six cleaning steps in a bottles washer are:1) Pre rinse by 3 jets. 2) Pre caustic soak 1 3) Pre caustic soak 2 4) Hydro cleaning 5) Pre final rinse treatment 1 6) Pre final rinse treatment 2

6. The cleaned bottles are transferred from the bottles cleaner to the filler conveyor and are sent for filling to the filler. 7. The EBI machine separates the defective bottles i.e. the bottles with chipped finish are discarded & the once those are dirty are sent for rewash. This machine is a credible and precise rotary type inspection machine that automatically inspects damage, flaw, external substances (bottom and sidewall of bottle) and uncleanness in an empty bottle. This inspects the

sidewall of glass containers that camera & illumination is installed to inspect the inclusions, bubbles, stone, bird wings, laps etc. The machine performs an inspection without contact between bottle and machine regardless the production speed. This machine uses a preloaded image that is used as standard, the bottles passing through the machine are compared to the standard. 8. Beverage is filled in the bottles by the filler and is crowned simultaneously by the same machine. This machine is a computer controlled machine that fills pressurized carbonated drink in the bottles. The vent first sends carbon dioxide inside the bottle that in turn develops a counter pressure that opens a valve which enables inlet of beverage in the bottle. As soon as the bottles are filled the filled bottles are transferred to the crowning section where the crowns are fitted on the heads of the bottles which seals them. 9. The inkjet printer prints data as required on the filled bottles. The printer generally prints maximum retail price, batch number of production, production date & time on the bottle. The data to be printed on the bottles is set by a computer system in the machine comprising of a display & keyboard. The data to be printed is set using this system. 10. The filled bottles are inspected manually for leaked bottles, bottles that are not filled properly & bottles that are not crowned properly. The bottles that are found defective are removed and are sent for refilling. 11. The filled bottles are transferred from the conveyor line to the crates by caser.

Curbing Breakage of glass bottles on RGB line

Prime locations of bottles breakage1. 2. 3. 4. 5. 6.

At the place where the worker loads the crates on the conveyor. At the EBI where bottles with chipped finish are discarded At the crate cleaner At the filling machine Along the conveyor belt ( bottles fall due to slipping off the conveyor) At the location where crowned bottles are inspected for defects.

Immediate actionsPlacing bins of proper shape for bottle collection instead of drums used presently at specified locations.

Bins of such shape will enable proper collection of the bottles and easy replacement when filled. The bins should have wheels that would make them easily movable when they are filled helping the workers to remove them easily form time to time. Locations for use of such bins:- EBI machine, crate cleaner & inspection site of crowned bottled. The size of the guard rails on the conveyor could be increased on the turn, this will reduce the slipping of bottles on the turns because generally many bottles fall on the turns which result in bottles breakage.

Long term plansAt the loading site where worker puts the crates on the conveyorA conveyor could be installed below the main conveyor that moves opposite in direction to the main conveyor, it would carry the bottles to a specified point where the bottles could be collected and removed periodically. This is the only possible measure at this location because there is no room for placing a bin for collection of bottles.

The above sketch shows the side view of the conveyor that could be installed below the main crate carrying conveyor this conveyor would carry the bottles falling from the crates.

The sketch below shows the front view of the conveyor that could be installed below the main crate carrying conveyor, metal sheets or metallic mesh could be installed as side guards which would guide the bottles falling into the moving conveyor below the main conveyor.

At the EBI where bottles with chipped finish are discardedA conveyor could be set here also carry the bottles to a specified point where the bottles could be collected and removed periodically. Or AGC (automatic guided carts) could be used to collect, carry & dump the bottles at a predefined site.

AGC (automatic guided carts) are smart carts that move on pre specified path marked by magnetic tape. Set of two AGCs could be deployed at every site to collect and dump the broken glass bottles.

System for removal of glass spilled on the floorCommercial vacuum cleaner can be deployed for removal of glass pieces on the floor. A high suction vacuum cleaner can lift small and larger pieces of glass. This could be operated by just a single person at certain time intervals in the production area especially inside the filling room to remove glass pieces from the floor.
