The sorting lines offered by Welko, in cooperation with a Business
Partner, are completely automatic and can be programmed by an industrial
PC with LCD display.
The statistical data on production, auto-diagnostic data and control
logic of the line are entrusted to a V.M.E. system composed of a PC and
Automatic sorting line
The line is able to supply statistical information on the production
and on error condition occurred, via the remote terminal with
subdivision of the date, hour and type of error.
Each handling is achieved with the help of stepper motors controlled
in couples by drivers especially devised for this kind of automation.
This ensures a precise control over the speed and position of the
ceramic product with no need for retroaction, encoders or speed
The absence of mechanical transmissions allows minor wear and need of
maintenance and ensures a perfect machine flexibility and absolute
synchronization of the parts that must move together.
This type of motorization allows to obtain a lower energy consumption
and asks for no maintenance.
The motor speed and torque are adjusted according to the production
to be achieved and to the product size: all this enables to use the
sorting line potentialities in the best way and to handle the sorted
material with the utmost care.
All the outlets are equipped with self-diagnosis to promptly signal
Two row sorting table
The ejection system (patented) is particularly interesting. With this
system, the tile is ejected by four electronically controlled pneumatic
cylinders that regulate the inclination of the tile and place it gently
on the underlying stack with the aid of motor-driven rubber rollers,
which ensures perfect squaring of the stack and limits noise pollution
The stackers are double-chained and operate continuously. While one
stack of tiles moves downwards toward the traveling lift on the first
chain, a new stack begins to be formed on the second one. This provides
faster handling of the production cycle and ensures adjustment to the
The traveling lift consists of two independent chains with
step-by-step motorization, which constantly guarantees an optimum
support surface for the stack of tiles.
Size change is completely automatic and can be set at the terminal.
