requests
1.1 satisfies the highest printing
speed in 15,,000/now and then 250 meters/minute
1.2 satisfies prints the host electrical
machinery and the servo electrical machinery synchronism
1.3 satisfies 色组 nimble disposition
1.4 satisfies 色组 the printing ink

1.5 receives the paper and gives the paper
machine independence
1.6 meeting and parting press high speed

1.7 requests in the network may the tensity

1.8 environment adaptions request three
phase voltage in 280V ~ 512V, the temperature in 0 ~ 55, the relative
humidity (below 90%, condensation), environmental condition and so on
under vibration, impact, cannot the normal operation
After comprehensively carefully examines the above
request, chooses any type the electrically controlled system and the
field bus, but also should compare their performance price compared
to, as well as realization correspondence convenience simple or not.
Former reason is self-evident, the performance conforms to the
requirement, the price then is the important determining factor.
Latter is because some network correspondences when carries on
the initialization, requests each to hang in the network the pitch
point all must separately make the initialization parameter
hypothesis; But some main lines merely request in the master
station to make the initialization to all pitch points.
Obviously, when the disperser disposition pitch point wants the
one by one makes the initialization, its operation is inconvenient it
can be imagined. Especially installs in some pitch points in the
place which quite narrow and small is spatial once in a while with
difficulty arrives.
2. systems dispositions
After carefully compares the choice, we had
designated CC-Link takes the printer electrically controlled system
the field bus.
The printer electrically controlled system (4 colors printers)
are by 1 host traffic-control center, 9 frequency changers, 3 servo
electrical machinery, 9 step 进电 machine, 22 long-distance I/O
unit, as well as 1 hangs on the main line the man-machine contact
surface composes. Disposes as follows:
Host traffic-control center: A2ASHCPU + A1SJ61BT11
Output module: A1SX40 or A1SY10
Long-distance module: AJ65BT-R2 x3
I/O module: AJ65BTB1-16D x2
AJ65BTB1-16T x2
AJ65BTB1-32D x10
AJ65BTB1-32T x10
Man-machine contact surface: A975GOT
Frequency changer: A540-30K-CH x1
A540-0.75K-CH x8
Servosystem: MR-J2-40A x3
The system hardware diagram like chart shows:
3. system functions
3.1 hosts control
This system carries on the master station control
through A2ASCPU, through each 色组 CC-Link the long-distance I/O
module, the execution inputs and outputs logical processing, and
receives the paper for the paper to process respective logical control
by independent FX2N-CPU, the correlation information returns to the
master station through the CC-Link network, coordinates by the master
station each 色组, the master station simultaneously returns
mutually locks the information, by gives the paper and receives paper
CPU to carry on processing.
3.2 speeds synchronization
In the system the encoder which brings by the driving
electrical machinery outputs parallel to 3 servosystems in, completes
the speed synchronization function. Simultaneously the passable
man-machine has lain between the surface hypothesis related trimming
parameter, again by master station CPU through the CC-Link network and
the servosystem communication and the hypothesis, in the adjustment
servo electrical machinery and the driving electrical machinery
速比, achieves the tensity control.
3.2 色组 printing ink
In the system lies between the formula function through
the man-machine which the surface brings, may save more than ten kind
of different print requests the printing ink hypothesis, may on-line
freely assign out, the memory and the revision. Supposes the
definite value to lie between through the man-machine face the master
station CPU transmission, again transmits from the CC-Link network to
is responsible for the printing ink the frequency changer.
3.3 调板
Needs to carry on the adjustment in the polychrome
printing to each 色组 color printing, in the system
lies between the surface through the man-machine to be possible the
real-time adjustment engraving plate position, in the printing process
like discovered any 色组 existence color printing does not permit,
the passable man-machine has lain between the surface hypothesis by
the master station to each group of step of 进电 machine adjustments
engraving plate proportional type control.
4. 色组 mixing
Because each kind of customer request is
different, the host controls the CPU already in advance hypothesis is
8 colors printing function, the production factory only needs the
corresponding fluctuation 色组, then may simple complete the
electrically controlled system the disposition work.
5. main frequency changers
As a result of Chinese customer special reason,
partial printing equipment use in voltage extremely unstable area,
therefore Mitsubishi electric machine design special function, power
line voltage when is lowest may when three-phase 280V normal
operation.
6. tensities controls
The tensity control system by the tensity
controller, the tensity detector and the magnetic powder brake is
composed, through the parallel mouth and the FX2N-CPU communication,
passes the CC-Link website and the master station again by FX2N-CPU is
connected. Therefore may lie between in the surface by the
man-machine to demonstrate the related tensity and the hypothesis.
7. breakdowns and report to the police
Because uses the CC-Link network communication,
in a frequency changer, each 色组, and receives the paper for the
paper also to be possible real-time to return to the breakdown
information and to report to the police the material, again lies
between by the man-machine the surface demonstration correlation
content and the processing method, is simplified the operator the
inspection working procedure.
8. simple services
Because the CC-Link network automatic loop check
function, in the network any long-distance module, FX2N-CPU and the
frequency changer also have the normal information to return to the
master station. When type many appear the breakdown, the CC-Link
network can automatically send out the related breakdown information.
The serviceman lies between in the surface after the man-machine
to obtain the related information, only needs the prompt replacement
damage the module, then may automatically reply normally, does not
need any again hypothesis.
9. networks initialization
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 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.
Also may use SW1D5-CCMAP-E software to establish the network
parameter.
10. applications surveys
This system completes the first printer in at the
beginning of 1999 the production and the payment customer use, until
now has produced more than 200, from does not have because the network
breakdown to create the production suspension.
