3. Automated dispensing system dispenses a wide range of solutions for textile exhaust
and continuous dyeing, textile printing, floor covering, pigment industries and more.
This automatic system gives you the speed, precision and flexibility to provide
accurate and repeatable recipes.
In addition to the control of dyeing machines, a fully-automatic control system
performs various functions. An alternative approach to totally automatic weighting is
to use simple or paternoster storage systems with manual weighing in a
down-draught booth, controlled by a check-weighing system. This is followed by
dissolving or dispersing and distribution from dispense tanks that can be linked into
the control system.
What is Automatic Dispensing or Dosing System

4. Why automatic system
 To avoid uncontrolled weighting mistakes
 To avoid waste of products both for chemical auxiliaries and powder dyes
 To ensure solution making consistently ( correct water temperature,
correct method of mixing, etc)
 To minimize production cost to a extent
❖ Eliminates human error, by removing human decision
making and intervention
❖ Delivers high throughput in the lab

5. Outline of automatic dosing system
1. Transfer of recipe details to colour and chemical dispensary

dispersing and distribution of dyes and chemicals
3. Control of additions of dyes and chemicals
4. Updating of planning, scheduling and stock inventories
5. Storage of diagnostic and management information, including
consumption and utilisation of resources
6. Graphical presentation of stored data to generate reports .

11. Bucket discharging platform.

7. Features of Data Color Auto dosing system
Productivity
Wide range of solution bottle options that meet the needs of every
dye lab. System can virtually run non-stop thanks to auto-feeding
conveyor systems. State-of-the-art robotic X-Y-Z mechanism delivers
fast, reliable and precise results.
Effectiveness of the system is enhanced through specially designed
“calibration-free” injectors, dispensing water and chemicals into
more than one dye pot simultaneously.

9. Flexibility
Datacolor AUTOLAB can dispense a wide range of viscosities making the
system suitable for multiple applications: exhaust and continuous dyeing,
textile printing, floor covering, pigment industries and many more.

10. Repeatability
The “Tube-Free” design and constant solution agitation guarantee the highest
level of repeatable results. Automated gravimetric dispensing provides full
traceability for each solution dispensed. The AUTOLAB SPS system ensures
solution preparation accuracy and exact concentration data. Networked to the
dispenser database for added recipe dispense accuracy.

11. Confidence
As the market leader in laboratory dispensing for more than 20 years,
Datacolor AUTOLAB ensures seamless recipe transfer and fast dispensing
throughput within the laboratory workflow process.

conditions of the system is displayed on screen at all times
•Software available in different languages

19. How it works
Datacolor AUTOLAB™ TF systems are tube-free, eliminating
the possibility of sedimentation and therefore any need to
clean the system. They use dedicated individual injectors
to transfer solution from each dye bottle, removing any
possibility of cross contamination. Quicker to dispense
than other tubeless gravimetric systems, Datacolor AUTOLAB
™
TF also offers unique advantages that help to further
automate the process and save time.

20. ❖ All products are physically weighed during
dispense, ensuring total control and traceability
❖ Simple but effective design injector, easy to
maintain and low cost
❖ Uses dyepot holding trays, with 6 dyepots
in each tray, to optimize dispense throughput
❖ Dyepot trays can be prepared in advance,
saving operator and operation time

21. ❖ Dispenses water and chemicals simultaneously,
accelerating dispense speeds even further
❖ Conveyors used to further automate the process
(up to 60 recipes can be dispensed without the
need for any human intervention)
