Wittenstein Moves with Efficiency
Efficiencies found in proper component application

Annual North American consumption of candy per person is nearly 25 lbs. Therefore, chances are you have eaten tiny sweets out of fancy boxes which were placed there by the packaging industry's most successful rapid transfer robot - the Delta Robot. Developed in the 1980's, the Delta Robot design is the most pervasive rapid transfer robot design on the market with applications in the packaging, medical and pharmaceutical industries. With pick and place systems consisting of up to 20 such Delta robots handling 100-2500 products per minute, there are a lot of sweets to go around.

The continual need for rise in productivity with robotics is met with various challenges. High reliability, low maintenance, redundancy and equable robot utilization are some of the key performance aspects which manufacturers face. Utilizing Wittenstein's TPM+ components reduces the space envelope and increases the throughput.

Re-designing for Efficiency
An original design of the robot included linear rack & pinion actuators. Moving to the TPM+ allowed for maximum functionality and a 75% reduction in components. The new design allowed for having all the drive components enclosed and protected against water and dust, reduction in space envelope and weight and improved performance.

By design, the TPM+ eliminates the additional rotating parts that are used in a conventional solution, i.e. additional bearings, couplings and larger shafts, which lead to decreased inertia of the actuator. The source of power in an electromechanical solution, the magnets, is moved closer to the load which improves stiffness and results in higher dynamics. Assembly time was reduced and controllability improved.
