First, directs the
word
As reels thread in a process working procedure,
and the strip is situated between 精梳 and between the coarse yarn.
Its primary mission is: Combines, 牵伸, the mix, becomes
the strip, further processes the unfinished hank roving 熟条,
improves the cotton sliver quality. And the strip working
procedure is decided the cotton spinning product quality the key, the
cotton spinning and the strip working procedure process unit
horizontal condition the cotton spinning product influence, more and
more brings to the domestic and foreign cotton spinning expert's
attention.
Like chart 1 shows is the ASFA306 drawing frame technological
process, after the drawing frame machine is 导条the frame, under
each side respectively puts 6 or 8 feeds into 棉条?1, each side
cotton sliver is a group. The cotton sliver by way of
导条Roller 2 and for cotton and kapok Roller 3, enters 牵伸
installs 4, passes through 牵伸 must the strip enter the arc drive
pipe along the front Roller surface 6, gathers together Cheng Tiaohou
by to squeeze Roller 7 to contract the smooth close cotton sliver,
again puts by the circle strip plate 8 orderly circles on the output
棉条?in 9.
At present, the textile mill and the strip workshop all are
safeguards the radio station by the man-power primarily, production
line automaticity very low, moreover reels thread the workshop to have
the temperature high, the gossamer many, the noise big and so on the
characteristic, this kind of bad environment to person's health very
disadvantageous, the work is also easy to be weary. In order to
enhance the productivity and the product quality, reduces worker's
labor intensity, my courtyard and the Hai'an spinning machine factory
cooperation develops the ASFA-306 new high speed drawing frame, and
proposed based on the CC-Link main line realization and the strip
production workshop equipment networking, the structure and the strip
production system enhances the production the automaticity.
Second, CC-Link network synopsis
CC-Link (Control & Communication Link ) is a kind
based on the PLC system field bus, is PLC the long-distance I/O system
and extends to the field bus technology development. The CC-Link
network in aspect and so on timeliness, disperser control, with
intelligent machine correspondence, RAS function has newest and the
highest function, simultaneously, it may be connected with each kind
of scene machine building factory product, provides various merchants
equipment for the user the use environment. This network has
satisfied the user to the opening structure and the reliable strict
request, it has the following characteristic:
?nbsp;the CC-Link network may form the high velocity
and the long-distance range application configuration, enables its to
adapt the network multiplicity,
When the speed is 156bps , after the signal
distance may reach 1,200 meter Canadian repeater, the signal distance
is farther;
?nbsp;uses the ordinary shielded twisted pair,
greatly reduces the wiring cost, the antijamming ability is strong;
?nbsp;has automatically on-line restores the
function, waits for an opportunity the host to control the function,
shuts off from the station function, the confirmation connection
condition function and
Test and diagnosis function, therefore, may constitute
has the redundant reliable network.
?may connect the following three kind of long-distance parts
in the CC-Link system:
Long-distance I/O - merely processes
the switch quantity the scene part, for example digital I/O or air
operated valve.
The long-distance installment - can process the
switch quantity and the digital quantity scene part, for example the
simulation measures I/O, MELSEC-FX series PLC.
The intellectualization long-distance - has CPU and to be able and the master
station and other station communications scene parts, for example
personal computing.
Based on the CC-Link above characteristic, we designated CC-Link
takes and the strip production system field bus.
Third, system hardware architecture design
1. System disposition
And the strip working procedure usually divides into the
reason and the strip and two and the strip, 1#, 3#, the 5# drawing
frame completes the reason and the strip, 2#, 4#, the 6# drawing frame
completes two and the strip, eight drawing frames production workshops
layout like chart 2 shows.
Corresponds each drawing frame to have the valve island control
the operation machine to carry on trades the spatial tube and pushes
the full tube operation. 1#, the 2# conveyer belt uses to
transmit the spare spatial tube, controls it by the frequency changer
to open stops and so on the operation. The 3# conveyer belt uses
to transmit processes to the next working procedure full tube, because
of it continuously in movement, therefore directly the output module
which expands by the master station controls through the contact
device.
And the strip production system composition is: 1 host
traffic-control center, 8 FX2N the series PLC control
drawing frame took the long-distance installment station, 4 use in the
sensor signal input long-distance I/O module, 1 uses in the failure
indication long-distance I/O module, 8 control operations machine
complete trade the valve island which the tube operates, 1 individual
machine contact surface, 1 frequency changer as well as 1 personal
computing, all these modules all hang on the CC-Link main line.
System segment diagram like chart 3 shows.
Disposes as follows:
Host traffic-control center: A1SJHCPU+A1SJ61BT11, supposes
is the 0# station;
Long-distance installment station: FX2N PLC+ FX2N-32CCL, takes 2 stations;
Long-distance I/O module: AJ65SBTB1-32D, takes 1 station;
AJ65SBTB1-32T, takes 1 station;
FESTO Corporation CPA valve island, takes 1 station;
Man-machine contact surface: A985GOT+A8GT-J61BT15, takes 1
station;
Personal computing: Personal computing +A80BDE-J61BT,
takes 4 stations;
Frequency changer: FR-A500+FR-A5NC, takes 1 station.
2. System function
1# long-distance I/O module AJ65SBTB1-32D takes 10#, the
20# operation machine (pushes spatial tube with) 上光 the electric
pickup as well as 1#, the 2# operation machine (by valve island
control) on each air cylinder the position transducer signal input (8
drawing frames altogether need 4 long range inputs modules and 8
valves island). When 2# drawing frame (by FX2N PLC
control) when feeds into 棉条?appears the spatial tube, by
artificially 棉条?transports the 1# drawing frame output replaces
the spatial tube, and will empty the tube to move to the 2# conveyer
belt (to control on the free position by frequency changer).
When the 20# operation machine 上光 electric pickup examines
front not the spatial tube, then by the certain frequency start
frequency changer, leads the 2# conveyer belt revolution, enable the
spatial tube to arrive; Otherwise, the conveyer belt stops.
Long-distance I/O module AJ65SBTB1-32T meets has 11 indicating
lamps, takes the 1-8# operation machine and the 1-3# conveyer belt
scene breakdown demonstration. The man-machine contact surface
lays aside to the workshop scene, may monitor the entire workshop as
necessary the movement situation, when breaks down, distinguishes some
corresponding indicating lamps to perform to demonstrate, and may
control the overall system to open stops. At the same time, may
establish the frequency changer on the man-machine contact surface the
start frequency and the rise time, and may carries on the surveillance
to its movement frequency and the output voltage. The personal
computing lays aside in the workshop control room, meets the oral
plate A80BDE-J61BT13 company through CC-Link to enter the system, took
in the system an intelligent station, each kind of breakdown carries
on the real-time monitoring and the statistics to on the workshop
production output and the drawing frame, the statistical result by the
report form (including date report form, month report form and
breakdown report form) the form output.
Fifth, system application software design
The system software design approximately includes
following four aspects:
1. The SW5D5-GPPW-E software package provides which with the Mitsubishi Corporation carries on between the master
station and various substations the signal procedure design.
1) network initialization part
Carries on the unified plan to the entire
CC-Link scene network, determined various units the component type,
the network single number, various units occupy the station number, as
well as each station characteristic, the step is: The parameter
establishment - renovates - the parameter
carries on the data link with the buffer in - to write
the parameter - to renovate to E2PROM - the
parameter carries on the data link with E2PROM in.
2) along controls the procedure to be partial
When various modules data link is normal, namely
transfer corresponding module processing subroutine. This system
Chinese Communist Party company enters 25 modules, separately
transfers this 25 stature procedure then.
2. uses SWOPC-FXGP/WIN-C software which the
Mitsubishi Corporation provides to wrap in on FX PLC to carry on the control procedure and the signal
procedure design.
3. The SW4D5-GOTR-PACKE software package provides which
with the Mitsubishi Corporation carries on the GOT picture design, carries on the real-time monitoring to
the workshop movement situation. Altogether designs 5 pictures,
the distinction primarily picture, the 1# conveyer belt movement
picture, the 2# conveyer belt movement picture, the breakdown
demonstration picture, the breakdown personal history picture.
4. On the personal computing with Visual the
Basic 6.0 developments applications procedure "and the
strip workshop production management system", module mmscl32 which the
use increases (mdfunc.bas) - is CC-Link meets the
CC-Link correspondence fonts function which in the oral plate has, may
carry on in the user program to the part reads/writes, understood as
necessary the workshop the production movement situation, prints each
kind of production report.
Sixth, system characteristic
This system mainly has following several
characteristics:
1. Uses the Japan Mitsubishi Corporation the original
installation A series programmable controller (PLC) to compose the
computer control system, the realization modulation nimble
configuration. The product according to the industry standard
design, has the high anti-jamming and the redundant reliability.
2. The valve island uses is the FESTO Corporation's
original installation product, its model is CPA14. This kind of
valve island uses the module type structure may need to expand the
coil according to the user, most greatly may expand to 22. And
the solenoid valve signal and the input output signal in valve island
wiring, has completed by the FESTO manufacture, only must add on a
CC-Link connection module then to hang into the main line.
3. The system uses the field bus structure and the CC-Link
correspondence agreement, the realization digitization communication,
the function complete, the man-machine contact surface is friendly,
the graphical representation operation, the entire Chinese contact
surface, software may act according to the user request establishment
and the revision.
4. The personal computing took an intelligent station
hangs into the main line, causes the correspondence speed and is away
from all obtains the enhancement. And may the real-time
monitoring workshop movement situation, obtain the output information,
the printing production report.
5. Realizes two levels to report to the police: When
breaks down, the workshop scene worker acts according to the
acousto-optics which sends out to report to the police knows the
breakdown source, and also has the small man-machine contact surface
on each drawing frame to demonstrate this machine on the concrete
breakdown; Moreover, on main line man-machine contact surface
A985GT also can produce in the entire workshop the corresponding
breakdown source and the prompt information.
6. Production process semi-automatic control.
Because on the drawing frame certain breakdowns also must by
artificial remove, after like machine breaks the strip, the beaming
stops up the cotton and kapok and so on, therefore the present
workshop cannot realize the entire automation. But because has
used the main line structure, the entire workshop only had 1-2 worker
then, to reduce the personnel disposition.
7. Because uses air operated trades the tube installment,
trades the tube failure rate to reduce, in addition the main line
structure, causes the system coordination to be good.
