Take the bus through the pikchain®…..huiiiiiii!

Imagine, that you should design an intelligent vacuum conveyor together with our pikchain®. You want to control every suction cup individually and you know that this is not a problem with the pikchain-system.. But anyway, you feel uncomfortable, because you have for example 50 suction cups on the pikchain®: How should you pack so much cables and hoses in the pikchain®?

You need depending on the required air volume only 1 or 2 or max. 3 air hoses, that connect all electronic suction cups. The suctions cups itself will be controlled by a Bus-System .That means that you need only one Bus cable and one cable for the electrical power. And those few cables and hoses fit easily in the pikchain®!

Above you see the schema how such a system could be placed in a pikchain®.

Low Cost Automations cell!

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?
-automatic stacking
-intelligent sorting
-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

pikchain®: Driven by passion, part 3

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. 

[forcecaption]pikchain® with servo motor, which drives one of the rear sprocket via a shaft.

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!

Endless space …

If you think now that our pikchain® is taking off with the Enterprise and James T. Kirk, I must disappoint you.
I still have something that you might like:

It is still in the study phase and the first models have already been implemented, but I’m pretty sure we will soon be able to offer pikchain® for theoretically infinite distances or widths. We are going to transfer the modular system of our energy chains® to the pikchain®. In the future, we can transfer this image of an energy chain® exactly to the pikchain®.

For you this means: A huge selection of sizes and widths for “your” pikchain®. You can find exactly what you need.

Planet igus® is waiting for your arrival!


An important issue even today. What is tolerance? Who defines the tolerance? The tolerance is directly related to truth and freedom …

Before I become philosophical here … Back to pikchain®:

One of the questions about pikchain® that keeps coming back: How high is the tolerance of pikchain®, and the positional accuracy?

Well, the pikchain® has a positional accuracy of about 1 mm. The size is similar in width, maybe a bit less, but again we need a certain buffer so that the chain can still proceed freely and does not clamp.

Do you want to have a lower tolerance? Do you want to position more accurately?
Of course, the pikchain® can also become intolerant, or it can be positioned precisely in all axes.

It would then work, for instance, like this:

In order to obtain a desired position tolerance in height and width, the tool holder on the pikchain® is spring mounted. This tool holder is given a running carriage, which in turn enters into an adjustable roller guide. This roller guide is set for the desired tolerance once. Ready!
See also drawing.

We also have a solution for the positional accuracy in the longitudinal axis. The above-described tool holder gets a lateral bore into which a position mandrel can enter from the outside and keep the chain in position during the operation of the corresponding tool (e.g. drills). Ready!

You see: If we want, we can be damned intolerant. Otherwise we remain tolerant, freedom-loving Rhinelanders!
