What is Pneumatic System?
• A system that uses compressed air as a working
medium for transmission is known as pneumatic
system.
What is Pneumatic Tube System?
• A Pneumatic Tube System (PTS) is a system in
which carriers are sent through a network of tubes by
compressed air or by vacuum.
Why PTS?
• Pneumatic tube system has a speed of 6 - 8 m/s
• Saves time
• Allows your staff to concentrate on more important
work
Types of PTS
1. Point To Point System
2. Semi Automatic System
3. Fully Automatic System
1. Point to Point System
Simple A-B
connection
Bi-directional
2. Semi Automatic System
• Main station
receives and
delivers to multiple
stations
• Remote stations
are configured to
only send directly
to the main station
3. Fully Automatic System
• Allows any station
to send and
receive from any
station
Components
1. Blower
2. Carrier
3. Diverter
4. Tubes
5. Arrival Signal
6. Control Station
Components1. Blower
• The driving force of pneumatic tubesystem is a blower.
• Due to the air flow the carrier willstart to move in the transport tube.
2. Carrier
• Carriers are the containers that hold materials and goods as they move through a tube system.
• Size of the carrier is 15cm diameterand 20-30 cm long.
Components3. 3-way diverter
• Diverters act as a switching station
that allows a carrier to travel to its
destination in the most direct path set
up by the diverters.
4. Tube
• The carriers move through especially
fabricated gray plastic pipe.
Components5. Arrival Signal
• Diverters act as a switching station
that allows a carrier to travel to its
destination in the most direct path set
up by the diverters.
6. Control Station
• The area where the carriers are
exchanged.
Structure of PTS
Working
• We take the transport process from Station 3 to Station 2 as example.
• Firstly, the carrier enters into the tube system through the station 5.
• Then Diverter 1 is set at the left branch and Blower unit 1 generates suction by partial vacuum. Soon the carrier arrives in point A.
• Diverter 1 turns to the middle branch and Blower unit 1 produces compressed air to pull the carrier to point B.
• The carrier gets into Top slot 1 of transfer center by gravity and then falls into the car, which can move between the bottom slots back and forth.
• With the help of the car, the carrier arrives at point D.
• Blower unit 2 produces compressed air to push the carrier to station 2.
Advantages
• Decreased material delivery time.
• Carriers are transported at speed of 6-8 m/s.
• Can transport up to 3-7kg material.
• Less prone to human error.
• Lesser staff requirement.
• Reduced maintenance cost.
Disadvantages
• Heat is generated due to friction
• Bends in system cause deceleration
• Noise is generated
Applications
• In hospitals, for transporting test tubes or tissue jars,
medicines and blood products
• In banks for the purchase and removal of cash and
valuable
• In industries for sending raw materials
• In post offices for sending letters
Conclusion
• The pneumatic tube system is logistics
transportation system
• This system uses pneumatics as power, which is
controlled by computer
• This system could implement the task to carry goods
between systems or within system
