Question

When the start button is pressed, the conveyor belt is working. Products on the tape are counted by the sensor. Conveyor belt stops when there are 20 products. The lamp that gives the full information is on. The whole system will stop after the lamp lights for 15 seconds. Create the appropriate PLC system. Draw the ladder diagram?

Answer 1

PLC Programming for PLC Conveyor Motor Ladder Logic or Conveyor Belt Control utilizing a programmable rationale controller (PLC).

PLC Conveyor Motor Ladder Logic

Objective: The consecutive tasks as follows

1. At the point when START button squeezed
2. The engine will be begun
3. RUN (Green Lamp) sign light will be actuated
4. Engine Running, so Box will begin to Move
5. Closeness Sensor will distinguish when the case shows up at another end
6. The engine will be halted
7. RUN (Green Lamp) sign light will be de-actuated
8. STOP (Red Lamp) sign light will be actuated
9. An Emergency Stop press catch will be utilized to stop the engine whenever.
   

Relay Schematic :

• R: STOP Indication lamp,
• G: RUN Indication lamp,
• M: Motor,
• OL: Overload Relay (Motor Protection Relay),
• LS1: Proximity Switch,
• PB1: Start push button,
• PB2: Emergency Stop Pushbutton,
• CR: Contractor Relay

Operational Sequence :

• Operational Sequence :

  The beginning caught is impelled.

  CR1-1 closes to seal in CR1 or to lock the beginning order

  CR1-2 opens, exchanging the red stop pilot light off

  CR1-3 closes, exchanging the green run pilot light on

  CR1-4 closes to stimulate the engine starter and engine

  The crate/bundle moves and closeness switch (LS1) distinguishes the container when it came to and de-stimulate loop CR1

  CR1-1 opens to open the seal-in contact ( unlatched beginning order)

  CR1-2 closes, exchanging the red pilot light on

  CR1-3 opens, exchanging the green pilot light off

  CR1-4 opens to de-empower the starter curl, stop the engine, and end the arrangement
