DELTA ROBOT OMRON HORNET 565

Omron Hornet 565 is an ideal parallel robot for use in the food, beverage, pharmaceutical and medical products sectors. Designed with a high payload to support multiple outlets (multi-picking), it is able to follow a conveyor belt up to a speed of 1.4 m / s. The amplifier and controller integrated in the robot reduce the number of cables needed.

Delta or parallel robots and Omron Hornet 565

Omron Hornet 565 is a delta robot. The typical configuration of a delta robot follows a classic pattern: three high-torque servomotors are mounted on a rigid frame. On each motor shaft, an arm is mounted perpendicular to the shaft rotation axis. Some robots use direct transmission, in which the arm is mounted directly on the shaft, and some use a reducer. These “bicep” arms are connected to light rods arranged in parallelograms to limit the twisting movement. These “forearm” arms are connected to a central platform. The joints at the two ends of each parallel rod move freely, typically in spherical joints. On the lower platform it is possible to connect the final effector and several other options, including motors for additional axes of freedom. Most delta robots have at least a fourth axis which allows the rotation of objects.

The main advantage of the delta robots is that the heavy motors are fixed on the frame, allowing the moving parts of the robot to be very light. On the contrary, each motor of an articulated arm robot carries the weight of all subsequent motors. Due to the lever-based design, the motors must provide high torque to counteract the increase in the lever applied by the payload on the shaft. This results in the low payload of most delta robots needed to maximize speed.

While most delta robots have three arms and four axes of freedom, there are other configurations available. Omron, for example, offers the Quattro parallel robot which uses 4 motors with 4 parallel connections instead of the classic 3 parallel connections: this design allows the robot to carry a greater payload or to perform a faster cycle, even twice as fast as to a “traditional” delta robot.
