[Technical Field]
[0001] The present invention relates to an electronically controlled pattern sewing machine
and a method for controlling the same, and more particularly, to an electronically
controlled pattern sewing machine that automatically detects and programs coordinates
of a sewing line of a sewing object even if the coordinates of the sewing line are
not manually set and programmed, thereby reducing costs and making skilled workers
unnecessary.
[Background Art]
[0002] As well known, a sewing machine is a machine used to stitch fabric, leather, paper,
vinyl, and other materials together with thread to bond the stitched materials to
two layers or more, and an electronically controlled pattern sewing machine is a computer
sewing machine that replaces hand-powered and foot-powered cranks used in the general
sewing machines with a motor and a control technology of an electronic device to thus
automatically perform a sewing operation for various patterns through electrical signals.
[0003] An operation panel box is generally disposed on one side of the electronically controlled
pattern sewing machine so as to control and monitor the sewing operation of the sewing
machine.
[0004] So as to perform the sewing operation through the electronically controlled pattern
sewing machine, coordinates X and Y on the position of a sewing line and sewing functions
(for example, run, speed, stitch-length, trimmer, jump, and the like) are applied
to each portion of a desired design through a CAD program installed on a computer
or a punching device as program equipment only for pattern, and thus, coordinate data
is generated and converted into pattern data adequate to the electronically controlled
pattern sewing machine. After that, the converted data is stored.
[0005] Next, coordinates X, Y and Z for automatically controlling sewing movements of the
electronically controlled pattern sewing machine are converted into data adequate
to the electronically controlled pattern sewing machine through a program only for
the corresponding pattern, and the converted data is stored. The stored data is transferred
to the operation panel box through a storage medium like USB or network, and the operation
of the electronically controlled pattern sewing machine is controlled by means of
the operation panel box.
[0006] Further, a jig, which has a through hole formed to a shape of the pattern, is manufactured
and installed to fix a fabric in position, so that at the time of the sewing operation,
the fabric is not moved.
[0007] Before the sewing operation, in conventional practices, a test for the electronically
controlled pattern sewing machine is first carried out to check whether a needle of
the electronically controlled pattern sewing machine is accurately operated at a position
to be sewn on the fabric clamped by the jig. At this time, if the jig is not disposed
at an accurate position, the jig itself is made incorrectly, or the coordinates X
and Y are erroneously inputted from equipment only for program (for example, CAD or
punching device), the needle of the electronically controlled pattern sewing machine
hits top of the jig, and otherwise, the fabric fixedly located in the jig becomes
sewn wrongly. Accordingly, the test is stopped, and after the jig is re-controlled
and installed, the test is carried out again. Through the repetition of the above-mentioned
processes over several times, normal sewing is achieved, which undesirably requires
lots of time and steps.
[0008] In the conventional practices, accordingly, the electronically controlled pattern
sewing machine has to have high-priced program equipment like CAD or punching device
so as to design the sewing line and further has to need skilled persons for operating
the program equipment. In addition, a lot of time is unnecessarily consumed to repeatedly
perform the tests for the accurate installation of the jig and the re-installation
of the jig according to the tests, and accordingly, highly-skilled workers should
be needed.
[0009] Of course, the coordinates of the sewing object can be directly inputted and stored
one by one by means of the operation panel box, not by means of the CAD or the punching
device as the program equipment only for pattern, but in this case, it is very hard
to input one by one the coordinates of each sewing line through key buttons of the
operation panel box. Also, input time is very long. If mistakes happen during the
input, on the other hand, the coordinate input has to be performed again from the
beginning. Therefore, the coordinate input completion is not easy, and also, long
time is needed to gain skill in the manipulation.

[0029] Hereinafter, the present invention is in detail disclosed with reference to the attached
drawings.
[0030] An electronically controlled pattern sewing machine S according to the present invention
includes a jig 100 as known, a marking part 200 for marking a sewing line on a fabric,
a sensing part 300 for sensing coordinates of the sewing line, a sensed coordinate
storing part 400, a controller 500, a function setting part 600, and an operation
panel box 700.
[0031] In this case, the jig 100 serves to press the fabric so that the fabric is located
at an accurate position, without any movement, during a sewing operation, and further,
the jig 100 has a pattern-shaped through hole formed thereon so that a needle of the
electronically controlled pattern sewing machine S performs the sewing operation along
the sewing line of the fabric, without having any inhibition.
[0032] Further, the marking part 200 serves to mark the sewing line along a periphery of
the pattern-shaped through hole formed on the jig 100.
[0033] Also, the sensing part 300 serves to sense the coordinates of the sewing line marked
by the marking part 200. At this time, the sensing part 300 is provided to various
shapes through various methods.
[0034] For example, the sensing part 300 includes a light emitter 310 for irradiating light
on the fabric above the fabric, a light receiver 320 for receiving the light irradiated
from the light emitter 310 and then reflected on the fabric, and a pattern coordinate
operator 330 for calculating and operating the coordinates of the light reflected
on the sewing line or the periphery of the through hole of the jig 100 from the received
light to the light receiver 320.
[0035] In this case, the sensed coordinate storing part 400 serves to store the coordinates
of each point of the sewing line sensed by the sensing part 300.
[0036] Also, the controller 500 automatically converts the coordinates of each point of
the sewing line sensed by the sensing part 300 and then stored in the sensed coordinate
storing part 400 into sewing coordinates adequate to the electronically controlled
pattern sewing machine S.
[0037] In this case, the function setting part 600 serves to set various sewing functions,
such as a run function, a speed function, a stitch-length function, a trimmer function,
a jump function, and so on, on a portion to be sewn according to the sewing coordinates
converted by the controller 500.
[0038] Further, the operation panel box 700 serves to control the movements of the needle
of the electronically controlled pattern sewing machine S according to the sewing
coordinates converted adequately to the electronically controlled pattern sewing machine
S, so that the needle operates according to the set various functions.
[0039] Under the above-mentioned configuration, now, an explanation on an operating procedure
of the electronically controlled pattern sewing machine S according to the present
invention will be given.
[0040] First, the jig 100 made separately from the electronically controlled pattern sewing
machine S is clamped to allow the fabric to be supported thereagainst (S100). The
jig 100 serves to accurately locate the fabric on the electronically controlled pattern
sewing machine S, while pressurizing the fabric.
[0041] Next, the coordinates of the sewing line to be sewn on the fabric clamped by the
jig 100 are sensed by means of the sensing part 300 (S120). To do this, light is irradiated
onto the fabric above the jig 100 through the light emitter 310 of the sensing part
300 (S122), and after that, the light reflected after the irradiation of the light
emitter 310 is received by the light receiver 320 of the sensing part 300 (S124).
[0042] In detail, the light irradiated from the light emitter 310 passes through the pattern-shaped
through hole formed on the jig 100 and is changed, and the light at the changed position
is received by the light receiver 320. Otherwise, light, which is reflected on the
line marked (S110) along the through hole of the jig 100 by means of the marking part
200 like a pen, can be received. The received light is operated to coordinates X and
Y of each point of the sewing line by means of the pattern coordinate operator 330
of the sensing part 300 (S126), and the coordinates are stored in the sensed coordinate
storing part 400 (S130).
[0043] The stored coordinates are automatically converted into the sewing coordinates adequate
to the electronically controlled pattern sewing machine S by means of the controller
500 (S140).
[0044] Further, various sewing functions, such as a run function, a speed function, a stitch-length
function, a trimmer function, a jump function, and so on, are set by means of the
function setting part 600 on the converted sewing coordinates (S150), and next, the
electronically controlled pattern sewing machine S is operated by means of the operation
panel box 700 to perform the sewing operation according to the various sewing functions
set by the function setting part 600 (S160).
[0045] As described above, the electronically controlled pattern sewing machine according
to the present invention can automatically detect and program the coordinates of the
sewing line of the fabric even if the coordinates of the sewing line is not set manually
one by one or even if they are not programmed by the CAD or punching device, so that
there is no high-priced program, time and cost are drastically reduced, and the operation
is performed by the manipulation of even unskilled workers.
