High Performance Gripping Systems

The linear directly driven PPU-E from SCHUNK is still the fastest Pick & Place unit on the market. Due to strong demand, the company has extended the series by introducing the PPU-E 50 unit. The new product is highly dynamic and can handle weights of up to 5 kg. For a complete cycle with a 280 mm horizontal and 105 mm vertical stroke, the PPU-E 50 has a cycle time of 0.92 seconds with a tooling mass of 2 kg and 2 x 60 ms (for grip-per).
Both the small and the large PPU-E unit do not require movable motor cables, which are susceptible to break down. With its speedy cycle times and excellent repeat accuracies of 0.01 mm per axis, it is setting standards in the assembly of smaller and medium-sized parts in the electronic, consumer goods, and pharmaceutical industry. All the supply lines for current, control unit, sensor system, and pneumatics are plugged into the rear-ward, stationary connection. Because of this, cable brakes and plant malfunctions are a thing of the past.
The flexible and freely programmable PPU-E 50 is designed for a 150 mm vertical stroke, 280 mm horizontal stroke and a moveable mass of 5 kg. Its maxi-mum acceleration amounts to 100 ms-2, the maximum speed to 4 ms-1.
Excellent Repeat AccuracyThe narrow housing and the media supply via the back panel allow a compact, mainte-nance and assembly friendly sandwich construction of several units next to each other. Two integrated position sensors control the vertical and horizontal movement, and en-sure the high repeat accuracy. Intelligent controllers can control the cantilever arm and the actuators without a master control system. The required software is already inte-grated. This way, the unit can be easily commissioned by Plug & Play.
Up to six integrated valves provide all pneumatic tooling with air. This minimises com-pressed air and energy, and ensures enormous high cycle frequency. The energy and time-efficient unit seamlessly fits into the module program, and can be equipped via a uniform interface with various actuators from the modular system for modular high-performance assembly. Besides the basic version without gripper interface, the PPU-E 50 is available in six different configurations: With two, four or six air and sensor inter-faces, electric rotary units, two-fold air and sensor connections, a vacuum interface, and on option, with a venture nozzle or an aggregate. Moreover, the Z-axis can be equipped with spring load compensation and a parking brake.
Features                 • All in one – Plug & Work • All connections on the back panel – for optimal accessibility • No moving motor cables eliminate possibility of broken cables • Individual axes are independently programmable • Interpolation of axes possible.
Advantages • Higher system productivity due to minimal cycle times • Reliable processes due to excellent repeat accuracy • Minimised energy costs due to consistently light weight design • Higher system availability due to elimination of moving motor cables • The unit offers all the advantages of a direct drive – without any susceptible transmission of motion. No wear.n
