Mitsubishi – Which type of robot suits your application best?

With Robots becoming increasingly easier to use, and also suitable for a high number of industrial applications, they are also becoming more economical.  As us humans and robots increasingly share a common space in the manufacturing environment, we are naturally giving more consideration in the choice between a collaborative or cooperative machine.   Which type of robot suits your application best?

Collaborative Robots or Cobots are specially designed to implement safe human-robot collaborations such as Mitsubishi’s latest MELFA RV Series Assista articulated arm Robots.  Industrial Robots, which are cooperative Robots, are equipped with safety features such as Mitsubishi’s SafePlus safety system that use proximity sensors to safeguard personnel entering the operating space.  Cooperative Industrial Robots are generally associated with these applications based on these features due to their durability, high speed, payloads, accuracy and high repeat-ability, these are the ultimate requirements.  Programming is not performed by an operator and with set routines not changing frequently, then its at easy decision, cooperative would be your answer.

Due to recent advances in Collaborative Robots, the lines have started to blur when it comes to applications that require the same accuracy but the payloads are lighter, the batch sizes smaller.  When a Robot can be taught quickly by the operator to adapt or initiate a new routine, a better option can be the Collaborative.  There are many examples where a Robot may be a solution such as fine assembly work or sample transfers in bio tech applications.  The fact that there is now a cross over between a dedicated Cobot and an adapted Industrial Robot using a safety sensing system is relevant because the accuracy and repeat-abilty is now comparable.  Service lines are also similar which creates a new set of questions for the end user.

When defining the task with a new set of operating parameters, the first aspect that you should consider is the ultimate automation goal that you wish to achieve.  Knowing this helps you determine the type of contact between human operators and robots that is expected.  Humans and Robots sometimes have to work together on a common task and in this case, the work spaces of them both overlap both spatially and chronologically to combine the advantages and strengths of both parties.

In situations like this, Cobots would provide the best option, an example being Cobots are ideal when machines need to handle and hold parts whilst a human is working on them.  The ergonomics of a Cobot arm are very different to that of a human, the reach and repeatability are better, as is holding still for long periods.  Using Robot assistance in this type of situation can make a task far more comfortable for a human to complete.  Not only an improvement for the working environment, it also benefits quality and productivity.  Cooperative solutions would suit the application best if human operators and robots only briefly interact with each other.  This may also be the case for environments where humans are not working alongside the robot but require regular access to the Robot cell, examples of this are packing, palletising, loading machine tools and filling etc.

It is also important to consider the payload and cycle time requirements, both Collaborative and Cooperative Robot systems can be used when these aspects are not relevant.  Heavy components or fast processes can only be handled effectively by Cooperative Robots however.

You also have to consider the space available for the automation equipment.  Where position, speed and torque of the robot can be limited or stopped as a human approaches, it is possible to set up adjustable safety zones for Cooperative systems.  This is ideal for packing station where for example, a forklift has to come in an area to remove a pallet.  For assembly tasks where the operative is constantly working close to a Robot arm however, the arm would spend too long at a slow speed or be stopped.  Collaborative solutions offer improved efficiency if a task requires manipulation of a low payload and is located in a compact working space.

In order to define which Robotic solutions would best address their requirements, the end user needs to determine the level of flexibility in their automated processes.   Collaborative Robots can add flexibility easily to assembly processes that need to make lots of highly individualized products in low volumes and over short batch cycles.  Cooperative Robots are suited more for high volume production of items that may feature small variability.  The deciding factor is very often the ROI and sometimes this can be difficult to calculate, especially on new applications with lots of variables.

Mitsubishi MELFA Robots

Mitsubishi MELFA range of advanced MELFA robots offer speed, accuracy and compact design as well as long life as well as  delivering class leading benefits for small-medium robot applications.

Producing a comprehensive range of robot models to cater to the full spectrum of modern needs, all Mitsubishi Electric robots are powerful, fast and compact.

The product range includes the almost universal articulated-arm robots with 6 degrees of freedom and payloads of 2 kg to 20 kg and SCARA robots with 4 degrees of freedom and payloads of 3 kg to 70 kg for assembly and palletising tasks.

There are 2 special high-precision robots that are unique, with their parallel arm structure for very fast micro handling tasks with payloads of 1 kg to 5 kg as well as the flexible high-speed SCARA robot for ceiling mounting.

It is no longer enough for industrial robots to simply perform a single task with consumer needs evolving quicker than ever. Demands for robots with the capacity and flexibility to readily take on more sophisticated tasks is what the industry is now demanding. If you are looking  for intelligent solutions and a simpler approach to flexible and advanced production then the MELFA-FR Series provides this.

MELFA SafePlus features safe and collaborative work applications and allows robots and people to work together providing high speed and performance and high levels of safety. FA-IT Integration Functions alongside Mitsubishi Automation products provide high levels of functionality performance and ease of use which in turn supports next generation manufacturing.

MELFA Robots – RV Series – Vertical Robot

 

 

The RV-series offers a highly-dynamic 6-axle articulated robot for a high degree of quality. Cycle times of only 0.32 seconds increase their productivity and thus enable their use in systems at very high speeds. The double-arm structure not only provides a plus in terms of freedom of movement, but also more stability and versatility. Depending on the model, the robots are fitted with two to 70 kilograms load at ranges from 504 to 2055 millimeters. Work in very confined spaces,even with wall or ceiling installation, is no problem for the RV-series. All systems up to 20 kg have the same compact robot controller .

In addition, all systems are fitted from the factory with built-in Ethernet, USB, tracking, camera and additional axle connections, as well as manual inputs/outputs, and therefore run with an availability of over 99.9 %.

Highlights

  • Increase your productivity: Cycle times of up to 0.32 seconds with accuracy of up to ± 0.02 mm
  • Flexible workspace: Range 504 to 2055 mm with spherical workspace – also behind the robot.
