Why no new blog entries for the recent weeks? We have focused all our efforts on our trade show exhibit at HMI 2012. The results are 2 new trade show displays, both using angle sensors and SPS programming – the first truly operational pick&place application. 2 short videos can now be seen here.
There is also the new robolink catalog! 24 pages. Novelty headliners: There are now 4 joint types: Swivel joint (1 DOF), rotating joint (1 DOF), symmetric and asymmetric standard joint (2 DOF). You can now implement a total of 31 possible combinations, with articulated arm designs having 1 to 5 DOF (see pages 10-13 with prices, one with and one without angle sensors). PDF download here:

We presented our construction kit at INNOROBO from 14 March to 16 March. We would like to thank the many visitors who expressed their interest.
EURONEWS has a report about INNOROBO (4 min’s):
Well, what does the pikchain® have in common with a low cost automation cell
You don’t know the answer? That means that you don’t know our pikchain® good enough, the intelligent conveyor belt from igus.
The best way to improve your knowledge about pikchain is to come to Hannover and visit us at the Hannover fair HMI, which takes place between 23rd und 27th of April
Of course we are participating and among other new products (120 in total) we will show a complete low cost automation cell. .
The igus parts used to build this cell cost about 13.500 Euro.
Experienced machine engineers can design this cell for about 22.000 to 27.000€
What do you see on our booth?: What are pikchain®, Robolink and Drylin E doing?
-selective providing to robolink
– optical control by moving camera
-precise storing of work piece
– …the installation of more actuators is always possible
Briefly: Intelligent, flexible pick and place in the smallest space
Hello out there,
Today I just want to come back to the following topic: The drive.
In one of my last Blogs from 10th of December I wrote you that we have changed the rear sprockets. At this time I could show you only a drawing of the new design. You remember? If not, just take a quick look of it again.
Today I add for you 2 photos which show the reality of the new drive system. This concept has very important advantages:
- This drive system engages with the chain at many different places at the same time. So you have a very smooth start.
- The belt can be retensioned.
- Because of the innovative design the bending radius of the pikchain® doesn’t have any longer an influence to the size of the rear sprockets. Now you have one standard rear sprocket for every pikchain®-radius and you don’t have to think about pitches etc. anymore.
Of course there is still the other way to drive the pikchain®: One of the rear sprockets is connected directly to the servo motor, which is located at the backside of the pikchain®. See photo. If you like to have detail drawings, please contact me.
Of course you are free to drive the pikchain® directly by on e of the main pikchain® pulleys: See also my Blog “Driven by passion” But you need a special design for the pulleys. It has to have a profile that fits to the outer gliding elements of the pikchain® in this way, that the pulley is working like a sprocket. Again: If you wish detail drawings, don’t hesitate to contact me.
Don’t waste you time with the drive: Drive yourself to the real challenges to design your pikchain®.. If you have questions how to design the pikchain® drive: Just call us!
The hall sensor Honeywell SS443A has an open collector output.
Switching a load or PLC requires a relay or optocoupler according to the following wiring diagram. The protective diode is necessary in the relay circuit.
Due to the low response times, we recommend the use of optocouplers (e.g. Weidmüller 8950760000).
