What is Modular Automation?

Modular automation is the next phase of factory automation where the same production line is separated into modules and can quickly reconfigure itself to serve different needs.  We're ready for this trend.  Are you?

Advanced Solution for Tomorrow's Automation

Modular automation products

 

In today's world, there's a growing demand for the capability to immediately respond to changes in the manufacturing environment, such as labor shortages, natural disasters, and disruptions in global trade.

Many companies have begun implementing automation to increase efficiency and safety, such as transporting parts and working in hazardous areas.  It also seems that more and more companies are working on modularization, which allows a production line to be reconfigured according to the need.

The key to solving these challenges is the realization of "layout-free" automated equipment and production lines, which is the basis for "modular automation".

 

What is Modular Automation?

The word, "modular", basically means smaller parts of a whole that can be arranged in a different order.  It can be applied to a production line, a manufacturing plant, or products.

"Modular automation" is the next phase of factory automation where the same production line is separated into mobile modules and can quickly reconfigure itself to serve different needs.

Imagine each module as a Lego piece on wheels.  Each module would carry equipment to serve a different purpose and can be easily integrated with another module.  For example, a production line that typically packages apples can be reconfigured to package bananas.

 

By enabling the same production line to serve different needs, the factory can respond immediately to changes in demand in real time.

 

In the near future, there may come an era in which all production equipment will be self-propelled by autonomous mobile robots while communicating wirelessly, and layout changes will be guided by AI.

 

Benefits of Modular Automation

The flexibility of repurposing the same production line for different processes can improve productivity while saving space and labor.  The results are more cost savings, faster time-to-market, and less downtime.

 

Benefits of Modular Automation:

● Free layout

● Productivity improvement

● High-mix low-volume production

● Resolving labor shortage

● Space-saving

● Energy-saving

● Cost-saving

● Faster time-to-market

Helpful for Industries Requiring Small Batches:

• Food & beverage

• Chemicals

• Pharmaceuticals

• Medical

• Textiles

• Marine

• Printing

● Packaging

 

There are two main types of modular automation: semi-mobile and fully mobile.

 

Semi-Mobile Modular Automation

In semi-mobile modular automation, parts are transferred by transportation robots.

 

Semi-mobile modular automation line

 

Semi-mobile modular automation lines have certain modules fixed to the floor.  However, by integrating mobile robots with certain conveyor modules, mobile parts transfer becomes possible, and production efficiency can be improved by eliminating the manual transfer of parts between different process stations.  A mobile robot with a small turning radius can work in a limited space and improve space efficiency.

 

 

Fully-Mobile Modular Automation

In fully mobile modular automation, every module can move and reconfigure itself.

From Layout A to Layout B

Fully mobile modular production line

 

By modularizing and mobilizing the entire production line, more layouts can be customized for different needs.  In order to realize complete modularization, it is best to standardize on the same product technology in order to shorten the learning curve and simplify the wiring.  Since modules are designed to be mobile, it is also necessary to consider making the device lighter and more compact. 

 

 

The table below shows a comparison between "semi-mobile" and "fully-mobile" modular automation.  The U-shaped line in "semi-mobile" modular automation is fixed and cannot be moved.  As you can see, the modular production line method (fully-mobile) can be more flexible and can even add additional units to serve more needs.

Support Modular Automation with 

Modular Automation Compatible Products

For engineers that want to step into modular automation, it's best to consider battery-powered, small, lightweight, and high-performance products.  Manufacturers have already begun to offer products that fit the "modular" requirement.  It's also important to partner with a manufacturer that can support all the different axes of motion you need.

"Modular automation compatible products" are a group of products with the common concept of battery drive, small size, and lightweight.  They are ideal for mounting on self-propelled devices and mobile equipment and contribute to the realization of modular automation.  Similar to a "modular" production line, modular automation compatible motors, actuators, and drivers can also be mixed and matched for different purposes.

At this time, Oriental Motor's modular automation compatible products consist of the AlphaStep AZ Series family of DC-input stepper motors, linear actuators, hollow rotary actuators, and mini drivers as well as the BLV Series R Type DC-input brushless motors and drivers.  Supported industrial communication protocols include EtherNet/IP, EtherCAT, Profinet, CANopen, Mechatrolink, CC-Link, SSCNetIII/H, and Modbus RTU.

For Speed Control or Basic Positioning:

BLV Series R Type Brushless Motor and Compact Driver

Oriental Motor's BLV Series recently expanded to the "R Type", which includes a slimmer brushless motor and a much smaller driver that accepts battery power.  Features and functions are kept from the original BLV Series, such as ramp operation and low battery operation.

 TIP  Size motors to be sure

To guarantee that a motor will work for your specific application, please start by first completing an online calculation with our motor sizing tool  .  Once your required torque, inertia, and speed values are calculated, add a safety factor to account for unknown sizing parameters, then search for a motor that meets the requirements.

If you need help with motor sizing or product selection, please contact our tech support engineers  .
