> This article will aim at the servo
electrical machinery which the present most advanced computer
embroidery machine uses to make the thorough analysis, and union will
reach servo the fine characteristic by and its on the computer
embroidery machine actual utilization, will make the multianalysis.
The computer embroidery machine is the present most
advanced embroidery machine weapon, it can cause traditional the
handwork to embroider the flower to obtain the high velocity, the high
efficiency realization, and also can realize manually embroiders the
flower is unable to achieve "multi-level, multi-purpose, the unity and
perfect" the request, it is one kind manifests many kinds of high new
technical the mechanical and electrical product.
Before our country embroidery machine market continuously
by Japanese machine monopoly, nearly blind home production machine,
but along with these years development, the domestically produced
embroidery machine 如沐春风, starts in the market budding.
The domestically produced embroidery machine through the recent
years growth, the development, the quality had the very big
enhancement, the performance stable, also had the very strong price
superiority, the natural price is more obvious than the superiority.
Domestically produced embroidery machine before basic completely
uses Japan is the brand servo electrical machinery, now reaches the
servo to rely on the outstanding performance and to have the
competitive ability the price to break Japan is the brand monopoly
enters the embroidery machine profession, and achieves with the
domestic some computer embroidery machine production main item
enterprise supplies goods for a long time the agreement.
Embroidery machine system main constitution
Computer control system: The domestic majority is
the Beijing Beijing greatly bold company's system.
Moves the frame system: Two groups of step of 进电
machine impetus cloths frame in horizontal plane crosswise and
longitudinal shift, coordinates about the needle to embroider each
kind of design.
Main axle system: The main axle impetus needle
movement, the use ordinary electrical machinery adds the frequency
changer, slippery difference electrical machinery, servo electrical
machinery.
Towel embroidering machine principle of work
In this take single embroidery machine use servo
electrical machinery quantity more towels embroidering machine as the
example, common towel embroidering machine use three servos electrical
machinery: Main axle, D axis, H axis. The main axle
throughout revolves to a direction, act through the mechanical cam
gear impetus needle about, about towel embroidering machine common
needle above each minute 500, evenly embroidering machine above each
minute 1,000. The D axis uses in to adjust the needle-tip
direction, guaranteed on the needle-tip uses for to cancel the line
the opening to face the needle movement direction (relative cloth
frame to move), needle each about adjusts time. The H axis uses
in to trade the color and the bonus line, uses a positioning pin
automatically in to trade between the color and the bonus line cuts,
Rao Xianshi this axis guaranteed delivers on the line direction and
the needle-tip the opening direction vertical is advantageous for
cancels the line, needle each about act time.
Servo related parameter establishment
Main axle:
P1-00=31, establishes the servo to accept the pulse order the
pattern
P1-01=0, establishes the servo-control pattern for the
position pattern
P1-44=343, the electronic gear compares the member
P1-45=17, the electronic gear compares the denominator
P2-10=1, ServoON signal often ON
D axis:
P1-00=31, establishes the servo to accept the pulse order the
pattern
P1-01=0, establishes the servo-control pattern for the
position pattern
P1-44=1000, the electronic gear compares the member
P1-45=36, the electronic gear compares the denominator
H axis:
P1-00=31, establishes the servo to accept the pulse order the
pattern
P1-01=100, establishes the servo-control pattern for the
position pattern
P1-44=50, the electronic gear compares the member
P1-45=36, the electronic gear compares the denominator
P2-12=143, the cut electron gear ratio, trades the color
and Rao Xianshi needs to cut the electronic gear ratio
P2-60=1000, the second electronic gear compares the
member
Attempts to reach the servo
to increase parameter adjustment software Corresponding software establishment
Above for the basic parameter establishment, after waits
various axes test run to complete, then acts according to various axle
loads condition and the operation requirements different adjustment
correlation gain, lets the overall system movement steadier be smooth.
Reached the servo to provide extremely convenient software
in the debugging process (for example on chart), set at the automatic
inertia using the servo driver in to estimate the function determined
the load inertia to fill in software compared to JL/Jm, again filled
in the response frequency according to the operation requirements
which needed to extend B.W. After The choice match motor model,
software may calculate the gain parameter which a set most matches,
then downloads the driver. Three axial center, the main axle
faces a direction to revolve to the servo electrical machinery request
is not very high, the gain may adjust lowers some. The D axis
and the H axis high speed want frequently to open stops, the gain must
adjust high somewhat.
Reaches servo the characteristic
Reaches the ASD series take PM the AC servometer as the
main force, the control loop uses the high speed figure signal
processor (DSP), may be high speed, the high accuracy completes each
kind of plurality of controls the operation; In addition applies
modern control theory some achievements to the exchange servo drive
system sds. Uses the strength control technology, causes the
servometer the low-speed characteristic good, the gain automatic
control, the instruction smooth function design, the software analysis
and the monitoring, causes the ASD series exchange servo truly to
achieve the high performance, the high response, the high accuracy,
high is reliable, a 5 machine body the design thought, the
communication function strengthens (RS-232/485/422), connotation
positioner design, more convenient overhead construction cost lower
control plan.

Along with the domestic embroidery machine production
enterprise productivity promotion, the embroidery machine market
competition will be more intense. Reaches the servo electrical
machinery to rely on extremely has the competitive ability the price
and the outstanding performance also will certainly to receive various
embroidery machines production enterprise favour, also will open the
innovation in the textile industry the aspect. |
