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.
