1 DESCRIBE THE OPERATION OF THE BEVERAGE PRODUCTION LINE AND THE DETAILED PROCEDURE OF SECOND STATION

1.1 Describe the operation of the beverage production line

The valve control system brings water into the mixing tank, controls the stirring motor the mixing tank, and controls the water supply valve from the mixing tank to the line Pla bottles are cleaned, water is poured into the bottle through a system, and then the lid is closed

The closed bottles are covered with thermal packaging, then go through a heating sys so that the packaging adheres closely to the bottle body

The line has an image processing system that identifies water bottles that do not meet requirements, and pushes those products to another processing conveyor

A conveyor belt delivers cartons containing products Water bottles that meet the requirements are picked up by the robot and put into boxes (1 box contains 6 bottles)

The cartons with enough products are guided through the lid folding and gluing mechanism, and the bottled water containers are completed A manipulator robot is responsible for picking up finished boxes to the AGV robot for storage and distribution 1.2 The detailed procedure of second station

Second station’s feature: Receiving and classifying defective products Detailed procedure:

First, the station receives the defective product from station 1 When the product is delivered, the product detection sensor will trigger the conveyor belt to run forward Af passing the sensor, the product will be counted by the counter, and the cylinder at the of the conveyor belt will push out, preventing products from moving forward

After the counter counts 4 products, the second cylinder (in the middle of the conve belt) will push out, separating the products behind from entering the batch of produc4 between the 2 cylinders Then, the cylinder at the end of the conveyor belt collects it, producing a batch of 4 products After the cylinder at the end of the conveyor belt retra when there is a signal from the sensor at the beginning of the conveyor belt, cylinder 2 (middle of the conveyor belt) will retract, ready to continue the working process Statio includes two operating modes, AUTO and MANUAL Users can separately control eac device in the station in MANUAL mode or let the station operate itself according to the above procedure in AUTO mode

7 MAINTENANCE DASHBOARD FOR SOME DRIVEN EQUIPMENT 7.1 PLC S7-1200

− Maintenance cycle: to ensure system performance and safety and prolong life, PLCs need to be maintained and serviced every 4 to 6 months

− Maintenance methods:

+ General cleaning of the PLC to remove dust and dirt that affects the system's performance

+ Make sure the PLC operates in a dry, clean environment because humidity will h a negative effect on electrical equipment

+ Check the settings and parameters on the PLC and take notes + Make sure the PLC and inputs and outputs work well

7.2 Conveyor belt

− Maintenance cycle: conveyor belts operate at a higher frequency than the rest of the equipment, so they also need to be regularly maintained once a month − Maintenance methods:

+ Check the conveyor structure to ensure operating productivity as well as reduce risk of damage

+ Conveyor motors should be lubricated regularly Lubrication helps reduce friction reduce wear as well as prevent engine heat

+ Conveyor belts should be cleaned to avoid dust and dirt that will reduce their lifes and help the conveyor belt operate smoothly

+ Conveyor belts should be cleaned thoroughly, all impurities on the belts should b removed Make sure the belt is not worn Make sure the product on the belt moves evenly Damaged belts should be replaced immediately

7.3 Inverter

− Maintenance cycle: to prevent the inverter from reducing performance and lifespan, periodic maintenance is required every 4 to 6 months

− Maintenance methods:

+ Back up the program and check the parameters and current status of the inverte avoiding data loss after maintenance

+ Check the inverter's inputs and outputs and replace degraded components + Clean the inverter, ensure the device is not oxidized and use thermal paste as we coat the circuit with anti-dust substances to prolong the life of the device

14 7.4 HMI screen

− Maintenance cycle: Continuous use of the screen for a long time leads to accumulation of dust and dirt, affecting the lifespan of the device Therefore, HMI needs to be maintaine regularly, every 1 to 2 weeks
