The
exceptional performance of the J-16 has been demonstrated throughout many
years of actual production operation. Some of the unique features that
contribute to the unparalleled performance of the J-16:
-
The machine is sequentially operated by
reliable solid state programmable controller. Sequential operation requires
that Operation B begin only after the successful completion of Operation A.
This is far superior to fixed timer machines which will jam if operations are
delayed.
-
The J-16 is an optive mode machine. It
will overlook a great majority of minor variations in parts to be assembled,
but if conditions become impossible, for example; a bent nail lodged in the
separator or an incomplete assembly occasioned by a crushed ferrule, the
machine will stop rather than jam. In fact, the system monitors itself in
relation to the brush parts it is working with, what it has done and what is
likely to happen, then selects the course to take. The machine may choose to
revert back into the cycle and try again, reject parts unnailed and continue
on to the next brush or stop and indicate the trouble.
-
The purpose of this sophisticated control
system is to insure that the machine produces good brushes a greater
percentage of the working day, stopping only when circumstances become
extenuating.
-
Air actuated clamps on the handle and the
ferrule hoppers permit full range width and length adjustment of both in less
than 60 seconds.
-
Solid state electronic nail detectors monitor
nails leaving the separators. Should any nail fail to drop, the machine
promptly stops at the beginning of the next cycle and the failure location is
indicated. This feature eliminates finding hundreds of brushes with a nail or
nails missing.
-
The J-16 incorporates a patented handle
ramming mechanism. This device is force sensitive thereby insuring correct
insertion of varying length handles and eliminating broken or loose handles.
The ram is self-adjusting and rams all handles, requiring simple insertion of
one small part on large handles only. No extra parts to buy. The J-16
can accommodate many handle shapes including long sash, beaver tails, kaiser
and shasta. Even some squares can be assembled with the addition of a
specially engineered clamp assembly.
-
Incorporated in the J-16 are eleven
control sensors which relay information to the controller. These control
sensors monitor the position of various working components of the machine and
the suitability of the parts being assembled. All eleven control sensors are
operated at least once every cycle and therefore must be highly reliable to
insure long term dependability. The J-16 uses solid state hall-effect
switches requiring no mechanical contact at these eleven sensor points.
Switches have a life expectancy of 10’s of billions of operations. The logic
control center is a solid state programmable controller with EPROM logic.
Telltale lights on the controller will indicate malfunction of any of the
sensors and the air valves which are the most reliable available.
-
Unquestionably one of the most outstanding
features of the J-16 is the ferrule clamp (PAT. #3,747,983). By firmly
clamping the ferrule on the sides near the epoxy region and accurately
compressing the open end, it causes the longer walls to move apart, thus the
ferrule mouth is opened for more predictable and reliable handle entry.
Experience has shown that handle chamfering in most cases is no longer
necessary, resulting in substantial savings. Since the clamp grips from
the sides and does not rely on the conventional knife edge holding action,
ferrules with epoxy weeps or lumps at the bristle end and those ferrules which
are bowed from “over plug” are easily assembled. Ferrules flattened by the
trimming machine are opened and assembled as a matter of routine. Further,
when a void in the epoxy is encountered, the defective ferrule will be
crushed, the handle will not enter and both parts are ejected unnailed,
leaving the handle to be reused.
-
Pushbutton controls allow
step-by-step actuation of all machine functions or actuation of any individual
function alone. For example, it is not necessary to run a complete assembly
cycle to adjust the ram for depth of insertion, only the ram need be actuated.
