Sorting Control
The sorting function
All SK process monitoring systems are designed to operate in conjunction with suitable parts sepa-
ration devices such as gates or traps in order to separate any detected faulty parts from the previ-
ous good parts production. The SK bbx unit will give a sort signal via its sort relay to open and
close such devices. It is recommended that the machine be stopped at the same time so that the
operating personnel can evaluate the type of defect and to initiate possible corrective action. Alter-
natively, the machine may be allowed to carry on producing while randomly occurring defects are
automatically segregated. The machine will only be stopped by the process monitor if too many con-
secutive bad parts are made (adjustable via the "Tolerance" setting, see page 09).
The settings for sorting can be found inside the menu section (accessible via the M function key
and entry of an access code).
Setting the sorting parameters
Touch the numbered key to select the desired function. The related data field on the right side turns
dark. Enter the desired number, or press any number key to switch between Yes and No.
1. Sorting (Yes/No):
Sorting function is active for this channel when set to "Y".
When set to "N" this channel is not used for sorting.
2. Sorting delay:
Allows you to delay the sort signal. This feature is useful in cases where the detected bad part
needs some time to get to the actual sort position. The delayed signal prevents too many of
good parts from being sorted along with the bad one. The delay is entered in number of parts
(or stokes).
3. Sorting quantity (parts):
Determines the number of machine cycles or strokes for which the sort signal will be given.
This ensures that the faulty part has really passed the gate position. Any setting higher than 1
will sort one or more good parts along with the bad one which is generally recommended
for quality control assurance.
