>Picks wants:The high speed wire binding
machine belongs to the line cable machinery. The project will
put in order the wrap system in the extremely short time to develop
successfully, compared with the previous generation product the
improvement which will have in the control mode and the operation
aspect, will obtain the user the approval and takes. Reaches the
mechanical and electrical product is complete, has the very high
natural price compared to, simultaneously the thorough technical
support and the service system have won the customer favour.
This article emphatically introduces high speed content and so
on wire binding machine principle of work, technological requirement,
system disposition.
Key word: High speed wire binding
machine line cable profession tensity track
1 introduction
The high speed wire binding machine use mainly is
to the multi- stocks bare copper wire, the tinned wire, the
enamel-insulated wire carries on the lay-up. Control system
including man-machine contact surface, PLC, frequency changer.
The control difficulty lies in the tensity control, each kind of
protective measures and so on. Compares with the previous
generation system has the tensity the automatic tracking, the main
axle lubrication way, machine in the non- dirt design, commits a
footfault the way, the friendly man-machine contact surface, the
machine disposition, squeezes the installment, inducting guarantees
system and so on characteristic. 2 systems overhead constructions
design 2.1 hardware dispositions design Sees also the system diagram (chart 1).
Hardware design including man-machine contact surface +PLC+
frequency changer + magnetic powder coupling. 
2.2 technological requirements and technical parameter (1) technical parameter.The
high speed wire binding machine divides into following several kind of
types: 300 /,400 /,500 /,560 /,650, technical parameter like
table 1 shows. 
3 crafts analyses 3.1 tensities tracks The tensity track uses the import the magnetic
powder coupling, long accounts for the total length proportion
according to the current idea which on the man-machine contact surface
establishes, simultaneously unifies the volume diameter compared to
the hypothesis, automatically the extension distance which must output
through the PLC computation magnetic powder coupling, carries on the
tensity the automatic tracking and the initial tensity hypothesis.
Volume diameter hypothesis from 1.7-3.1, volumes diameters the
is more different than influence extension to be apart from the output
the maximum value. The tensity automatic tracking is for
guarantee receives the coil from the spatial core volume diameter to
Man Juanjuan in the diameter process the permanent tensity, avoids
causing the conductor to extend the loss and because the recover of
wire tensity does not stabilize causes to jump the stock, the broken
line. 3.2 communications controls Communication control: The main axle
frequency changer frequency assigns with the main axle electrical
machinery current movement rotational speed passes the RS485
communication. 3.3 volumes diameters compare the control Volume diameter ratio: The volume diameter
ratio supposes the definite value is 1.7, 1.9, 2.1, 2.3, 2.5, 2.7,
2.9, 3.1. The volume diameter compared to is 1.7 tensities
hypotheses is 8 grades, soon the magnetic powder coupling can provide
the biggest extension is apart from 8 divisions. Along with
counts the long unceasing increase, according to counts the proportion
which in the long on-line total length hypothesis occupies, causes the
output extension to be apart from gradually increases The
volume diameter ratio is 1.9, tensities hypotheses is 10 grades;
The volume diameter ratio is 2.1, tensities hypotheses is 12
grades; The volume diameter ratio is 2.3, tensities hypotheses
is 14 grades; The volume diameter ratio is 2.5, tensities
hypotheses is 16 grades; The volume diameter ratio is 2.7,
tensities hypotheses is 18 grades; The volume diameter ratio is
2.9, tensities hypotheses is 20 grades. The volume diameter
ratio is 3.1, tensities hypotheses is 22 grades. The automatic
idea is long, full volume automatic stop. 3.4 main axles lubrications Selects the machine oil lubrication method, the
natural circulation cools, guaranteed the main axle in 3000rpm time
effective lubrication, avoids the mechanical friction losing,
lengthens the main axle service life, reduces the revolution noise. 3.5 tensities hypotheses The request can on the man-machine contact surface
the direct-viewing input tensity size, the unit: Newton
The tensity in receives the volume 盘头 the diameter change
process the tensity maintenance to be constant from the spatial core
volume diameter to Man Juanjuan in. Therefore transfers the
distance from the magnetic powder clutch control output to have from
slightly to the big change, the tensity track also is from slightly to
the process which greatly changes gradually. 3.6 contracts the installment In the craft effectively requests to reduce the
insulation material the loss In the machine supposes three to
contract the installment, after guaranteed the conductor lay-up circle
entire, the safeguard thin wall insulated wire product characteristic,
effective reduces the insulation material the loss. 3.7 inducting guarantee the automated system The tensity controls by the volume diameter
compared to, automatically assigns the tensity rank is the maximum
output extension is apart from the value. May the reference line
total length hypothesis, the system automatically carry on the craft
parameter the disposition, the guarantee stranded wire in groups the
quality. 4 entire machine systems pictures Sees also chart 2, 3, 4, 5.
5 debuggings processes At the beginning of 5.1 debugs Mainly is carries on the frequency changer
parameter the corresponding establishment.

P11 - 5 P88 - 1 5.2 simulations boards calibration OFFSET/GAIN carries on the adjustment. First
0 voltages inputs time will simulate the board regulation of output
will be 0; When 24v voltage input, the simulation board output
voltage adjusts 10v, adjusts GAIN. 5.3 communications tests Adjusts successfully PLC and the frequency changer
communication. Writes the frequency only carries on the change
when the speed only then communication; When the main axle
revolves, carries on real-time to the frequency changer revolution
frequency reads takes, and the corresponding movement frequency will
transform the electrical machinery the rotational speed. 5.4 starts and the spot move test The system initiation has two ways. Way one:
Automatic start; Way two: The spot moves
After the automatic start is the start, the main axle speed is
automatic by zero 升 to the rotational speed which establishes.
The spot moves is in the craft requests when to overhaul the
equipment and each time threads carries on the operation. The
spot moves the speed also may carry on the hypothesis through the
communication way. 5.5 bases establish the volume diameter compares with
the line total length hypothesis In under the automatic start condition, monitors
in PLC the D1117 current value, in the observation electricity cabinet
ampere meter, records the current idea long value from the man-machine
contact surface, calculates the current idea long value to occupy the
total length hypothesis the proportion; Compared with changes
between the proportion and D1117 and the maximum value proportion
whether approximately does tally. And lets the machine long time
the movement, observes along with counts long unceasingly increases,
whether the D1117 current value also does increase along with it, and
proportion whether synchronization. 5.6 protective measures middle automatic movement effect
test Carries on the test item by item. When
defers to the request, the spot moves some protections also is the
function. When carries on this step of test, certainly must be
strict, otherwise once has loses the misunderstanding to create the
very serious consequence. 5.7 clear zero High-speed counting wants prompt clear zero.
Otherwise counts long does not permit, directly affects the
tensity track the effect. 6 concluding remark Reaches the mechanical and electrical product
man-machine contact surface, PLC, the frequency changer, the servo,
warm control, foundation automation platform function and so on the
numerical control is fine, moreover has the extremely high natural
price ratio. In the dependence reaches FAE the technical
superiority, can provide the integrity according to customer need for
the customer the system plan and the disposition, is transforming into
the system integration plan as well as the OEM promotion product
application synthesis service domain. |
