/Pick-and-Place-Automation

This repository contains the Ladder Logic program for automating a pick-and-place mechanism using Siemens PLC. The system is controlled by a single push button, utilizing timers, counters, and outputs to manage the process of sensing, picking, placing, and transporting objects in a manufacturing environment.

Pick-and-Place Mechanism using Siemens PLC (Ladder Logic)

Project Description

This project demonstrates a Pick-and-Place Mechanism using Siemens PLC with Ladder Logic, featuring 4 outputs and 8 timers. The system is controlled by a single push button input and is designed to automate a sequence of object handling on a conveyor system, ultimately moving the object to transport. The system runs until a predefined cycle count is reached, after which the process stops.

Key Components:

  • Single Push Button (I0.0): The only input, responsible for starting and controlling the process.
  • Emergency Button (I0.1): Halts all operations immediately when activated.
  • 8 Timers: Ensure proper delays at each stage of the process.
  • 4 Outputs (Q0.0 to Q0.3): Control different stages of the system.
  • Counter: Tracks the number of cycles.
  • Equal Comparator: Ensures that the process stops after the set number of cycles.

Process Flow:

  1. Push Button Activation:

    • A single push button initiates the entire process.

  2. Operations via Outputs:

    • Q0.0: The system senses the object and moves the conveyor belt.
    • Q0.1: The robot arm picks the object from the conveyor belt and places it into the manufacturing process.
    • Q0.3: The robot arm picks the object from the manufacturing line and places it on the output conveyor belt.
    • Q0.3: The conveyor belt senses the object and moves it to transport, completing the process.

  3. Timers:

    • T1 to T8: Control various stages of the process, providing appropriate delays for sensing, picking, placing, and transport.

  4. Counter and Cycle Termination:

    • A counter counts the number of cycles.
    • Once the counter reaches the specified count, an equal comparator stops the process.

System Components:

  • Input:
    • Single Push Button (I0.0)
  • Outputs:
    • Q0.0: Controls the conveyor belt and senses the object.
    • Q0.1: Controls the robot arm to pick and place the object into the manufacturing process.
    • Q0.3: Controls the robot arm to place the object onto the output conveyor belt.
    • Q0.3: Senses the object and moves it to transport, completing the process.
  • Timers:
    • T1 to T8: Manage different stages of the operation with time delays.
  • Counter:
    • C1: Tracks and counts the number of cycles.
  • Equal Comparator:
    • Ensures the process stops after reaching the specified cycle count.

How It Works:

  1. Push Button Press: Starts the pick-and-place operation.
  2. Timers: Ensure delays at each stage—sensing, picking, placing, and transporting.
  3. Outputs:
    • Q0.0: Senses and moves the conveyor belt.
    • Q0.1: Picks and places into the manufacturing process.
    • Q0.3: Picks and places the object on the output conveyor belt and moves it to transport.
  4. Counter and Equal Comparator: Once the process completes a specified number of cycles, the counter stops the system.
