It’s not every new development project that turns established
processes on their head, but according to experts, dynamic sorting is just such
an innovation. The new sorting process is also expected to have long term affects
on glass processing. Dynamic sorting systems, such as Bystronic’s first´sort,
have everything that static systems lack: they’re fast, they’re significantly
less expensive and require much less space.
For a long time, large sorting and marshalling stations were the only
way to bring glass into the required ordered sequence for further processing
after scoring and breaking. With the development of a dynamic sorting process,
Bystronic is now able to provide a new, highly efficient sorting solution that
eliminates the major disadvantages of previous systems.
“The principle of dynamic sorting is similar to a hamburger slide in a
fast food restaurant”, explains Hans Gfeller, who was responsible
for developing first´sort. While we’re filling the storage area on one side,
we’re already starting to empty it on the other. These fully automatic
processes are controlled by two transportable shuttles, one for loading and one
for unloading. Pieces of glass remain in the sorting system storage only until
a pair of lites is complete. After that, they are immediately moved along,
ideally through a direct connection to a Bystronic insulating glass line or
laminated safety glass line, etc.”
In
this manner the first´sort sorting system generates a continuous, uninterrupted
flow of glass that can be practically sustained without restriction by
arranging orders one after the other. The Bystronic first’sort provides a major
key benefit for manufacturers in that it does not require huge, costly logistic
solutions with numerous harp racks as it includes a large temporary storage
area in the form of multiple harp racks.
Dynamic
sorting also allows for much shorter response times for glass manufacturers.
Express orders can easily be integrated into the ongoing process and thanks to
faster throughput times they can even be processed more quickly.
As
Gfeller explains, the essential idea of dynamic sorting is the multiple use of
compartments. “Static sorting systems arrange each lite into a specific
compartment. Dynamic sorting, however, gives us the possibility of using the
same compartment many times during a production sequence. Because of this, a
dynamic sorting system requires significantly less space than a static
solution.”
The
actual number of first´sort storage slots depends primarily on how many
different types of glass a customer wants to process. Generally the number of
compartments is around 200, but only about 150 of those are needed for sorting
lites. The other 50 serve as a safety buffer. If problems occur on the cutting
line, for example, production can still be maintained for up to 15 minutes.
Gfeller
is convinced that dynamic sorting is soon to become the new standard: “The
first´sort sorting system is our customer’s first choice. We’ve just taken two
more major orders with our first´sort sorting system as the key component.”
1. first´sort with a direct connection to an insulating
glass line
Standard
solution for mass production of insulating glass units with reduced need for
personnel. A glass rack provided with the system can be controlled by the portable
shuttles and thereby integrated into production, making it possible to feed
special glass such as laminated safety glass or coated lites into the sorting
system.
If
no direct connection is possible (for example because cutting and production
take place in separate areas), the lites are placed in harp racks. The system
has two docking stations so that the sorting process can be continued even if
one of the two harp racks is completely full and needs to be changed.
first´sort
also offers some persuasive advantages when using A racks . Optimizing the
sorting process means the operator does not lose time during de-stacking
searching for the right glass rack. Instead, racks can simply be filled one
after the other. That also substantially reduces the risk of mistakes when
setting individual items down on racks.
