rotaryARM swivel arm modules offer alternative to SCARA robots
R.A. Rodriguez is introducing new a range of IEF Werner rotaryARM swivel arm modules as the latest addition to its portfolio of affordable, uncomplicated automation components and systems. These modules operate in combination with the company's linear motion modules to create fast and cost-effective automation systems that are claimed to offer advantages over traditional robots.
The simple and compact design of the rotaryARM swivel arm module can be complemented by an integrated turning axis for the gripper to create a highly effective, space-saving robotic arm. Unlike earlier versions whose movement was restricted to a single 360-dgree turn before returning to the start position, the new rotaryARM design permits continuous rotation, resulting in reduced cycle time. Routing of pneumatic and electric cabling is simplified thanks to an integrated rotary feedthrough.
Developed to enhance the component handling for palletising applications, the simple design and slim construction results in a low mass of movement. This, combined with the integrated turning unit, servo motors and absolute encoders, ensures the rotaryARM delivers high speed and repeatable accuracy.
Another benefit is that, in combination with an IEF Werner x-axis linear module, the rotaryARM has a bigger range compared to many SCARA robots. The stroke of the x-axis can also be specified to suit the required working envelope.
Three standard variants of the rotaryARM swivel arm module are now available from R. A. Rodriguez to meet the needs of a broad variety of assembly, handling, packaging and palletising applications.
For the handling of rotationally symmetrical devices the first version has an NC-swivel axis but no turning axis; its gripper position changes continuously. On the second variant the gripper turning movement is synchronised by the toothed belt on the swivel axis to provide identical angular speed for the swivel and turning axes; the gripper position remains constant during the swivel movement.
On the third variant, an NC-swivel and NC-turning axis enable the gripper to be freely positioned during the swivel movement, giving even greater dexterity.
As the maximum payload of the new IEF Werner rotaryARM is 2kg, it is best suited to lightweight handling, typically in electronic, automotive component and pharmaceutical production.
