Plastic Injection L Conveyor Systems
What is a Conveyor System?
A conveyor system is a mechanical transport system that enables the automatic or semi-automatic movement of products, materials, or loads from one point to another. It is commonly used in factories, warehouses, logistics centers, airports, mining, food, and production lines.
The main purpose is:
- To reduce human labor
- To increase transport speed
- To ensure production continuity
- To enhance work safety
- To reduce costs
The Basic Working Principle of the Conveyor System
A motor generates motion → power is transmitted → belt/roll/chain moves → product is transported.
Simple flow:
[Motor] → [Reducer] → [Drive Drum] → [Belt] → Product Transport
Main Components of the Conveyor System
1. Motor ⚙️
Provides motion to the system.
Function:
- To convert electrical energy into mechanical energy
- To rotate the belt
Symbol:
2. Reducer 🔩
Reduces the motor speed and increases torque.
Symbol:
- M = Motor
- R = Reducer
3. Drive Drum ⭕
The main drum that moves the belt.
Symbol:
4. Conveyor Belt 🟩
The moving surface on which the product is transported.
Symbol:
Material:
- PVC
- Rubber
- Polyurethane
- Wire mesh
5. Rollers ⚪
Ensures the smooth movement of the belt.
Symbol:
6. Chassis (Body) 🏗️
The metal structure that carries the entire system.
Generally:
- Steel
- Stainless steel
- Aluminum profile
7. Tension Mechanism 🔧
Prevents the belt from loosening.
Symbol:
8. Sensors 📡
Provides product detection and automation control.
Types:
- Photoelectric sensor
- Inductive sensor
- Capacitive sensor

Types of Conveyors
1. Belt Conveyor
The most common system.
Usage:
- Package transport
- Cargo
- Food
- Factory lines
2. Roller Conveyor
The product moves on rollers.
Advantage:
- Low energy consumption
3. Chain Conveyor
Used for heavy load transport.
Usage:
- Automotive
- Palette transport
4. Screw (Helical) Conveyor
Transports powder or granule materials.
Usage:
- Cement
- Flour
- Feed factories
5. Modular Conveyor
Consists of segmented plastic belts.
Advantage:
- Easy maintenance
- Hygienic structure
Automation in Conveyor Systems
In modern systems:
Sensor → PLC → Motor Driver → Conveyor
Equipment used:
- PLC
- Inverter
- Servo motor
- HMI screen
- RFID reader
Example of PLC Control Logic
Scenario:
- When the sensor detects a product, the belt operates.
Simple logic:
IF Sensor = ON
THEN Motor = RUN
Electrical control symbol:
[S] ----(M)

Basic Formulas in Conveyor Calculations
Belt Speed
v=πDn60v=\frac{\pi D n}{60}v=60πDn
- vvv = Belt speed (m/s)
- DDD = Drum diameter
- nnn = Revolutions per minute
Power Calculation
- PPP = Power
- FFF = Force
- vvv = Speed
