Portal with PLS
PLS Application model for easy and for ambitious programming
The cell realizes an assorting and inspection
process. The assorting is with respect to the weight of the cylindrical
objects. The weighing is a pneumaticallly balanced semibeam with strain
gage sensor as comparator. The balancing is a control task for the PLS and
its ADC and DAC components together with the control PID-algorithm. After
weighing different decisions are provided: placement in rising weight order
on the rack or offsorting and elimination out of the unit etc.

Injection Moulding Machine
SPK97 is also an application model for PLC, pneumatics, hydraulics and
tool making. The machine on rollable stand is small, surveyable, transparent
and less dangerous. Heat and force effected parts are carefully isolated.

Moulds:
Moulds in original design with the following characteristics:
Manufacturing cell with injection
moulding machine and robot
This cell combines our
automated injection moulding
machine SP3K with a robot. The result is a manufacturing cell with
the process steps feeding, unloading, removing the sprue, checking and
final packing.
Build-up:
The Robot is placed on a table suitable to SPK97.
The table is bolted to the frame of the SPK97.
On the table are placed:
Magazin with separator
Blade turner with direction contro
Sprue cutter, packingbox
Optional image inspection system
The Injection Moulding machine is equipped with an
interface for communication
The machine safety cover has got a controllable flap
The mould "screwdriver" is automated and
prepared for the feeding of the blade
The robothand has got long fingers to grip the blade.
Procedure:
The robot takes the blade from the separator.
The placement of the blade is checked. If necessary
the blade is turned.
On its way to the mould the robot turns and swings
its hand. The SPK97 signals a ready and opens its coverflap.
During feeding the moulding machine is blocked.
The robot waits for the injection procedure being
finished and unloads the perfected screwdriver.
The sprue is cutted off.
Before packing an image inspection system can check
weather the moulding is correct.
small intelligent arms
Robot for pick and place and coating
3(6) axes
The robot is for point-to-point operation. At 20% speed
it is possible to execute any linear or circular paths continously. Therefore
it is well usefull for distributing and coating purposes f.e. of glue
or sealants.
work area: spherical ,radius appr. 500 mm
playload: 0,5 k
Positioning: 0,1 mm
speed: 1 m/s
steppermotor drives with special gearing for shoulder,
upper- and forearm
pneumatic drives for hand svinging, turning and gripping
with adjustable blocks
Two fingers hand in basic configuration. Additional functions
are possible.
Control:
through the soft-ware program PC-Posi and internal
or external PC. PC-Posi is a very flexible program for the control
of up to 4 stepper motors with any speed and ramps as well as for
digital I/O . It includes also a soft ware PLC with functions and
language similar to Siemens step7.
The unit includes all industrial standard functions
as f.e. :operation modes: setup, hand, cycle, automatic, teach-in,
other features are: cycle counter, repeater, crawling and fast speed,
I/O tests, relative or absolute positioning a.s.o.
Job related programs are saved together with their specific parameters.
TeLC offers
the complete solution: Robot to do the customers job.
The Robot is our own design, we make it ourselves
included the special gearings.
It allows the visualisation of the testspecimen , the measurement of the
traverse contraction and the displaying of the „true“ stress
during test run. Also image dokumentation in protcol is possible.
Software exists
allready for numerous tests. Software can easily be changed / created by
the user himself, e.g.:
Machine is available in table and compact
version and can come with a huge selection of tools. For more details visit
