Description

{Jump stitch discrimination method for embroidering machine}

The present invention relates to a method for discriminating a jump stitch of an embroidery machine, and more particularly, to a new method for discriminating a jump stitch of a embroidery machine so that a desired optional device can be additionally mounted and used without changing the embroidery machine.

Embroidery machines are used to embroider the necessary shapes for various textile fabrics such as clothing fabrics. A conventional automatic embroidery machine is a mechanical device that embroiders a desired design while the frame fixing the textile fabric is transferred in the X-axis and Y-axis directions while the needle bar moves up and down based on the embroidery design data.

In the embroidery machine, there are several heads, and each head has a needle bar so that several operations can be performed simultaneously for mass production. In addition, each head is connected to the same rotating shaft so that the needle bar of multiple heads can be moved up and down at the same time using a single axis motor. Recently, more than 100 head embroidery machines have been produced.

As the embroidery pattern is expressed in threads of various colors, each head has several needles, not one needle. Recently, it is equipped to use up to 15 colors.

[Basic control method of embroidery machine]

In order to drive the embroidery machine, the embroidery data is first required. The embroidery data is a computer-generated file, and the embroidery machine reads these files and moves the needle bar and the embroidery frame for optimal embroidery.

Embroidery data is created on a computer as a CAD program, and the generated data has different formats for each embroidery machine maker, but the basic configuration is as follows.

The state of embroidery needle is composed of X feed amount, Y feed amount, and function code, which are consecutively listed. Here, the X feed amount and the Y feed amount are mostly composed of relative coordinates, indicating the displacement amount from the current position to the next position. Using the function code, you can change the color of the thread, or command to cut the thread.

Almost all embroidery machines stipulate 12.7mm of data that can be expressed in the needle data.

The basic transfer unit of embroidery data is 0.1mm and is composed of 1 byte (0 to 255, or -127 to 127), so it can be expressed from -12.7mm to 12.7mm.

[Details of the function code]

In addition to the command to change the color or cut the thread, there is a function code showing the embroidery effect.

[Jump command]

The jump command is a function that prevents stitching at the corresponding immersion of embroidery. By operating the solenoid or motor, the needle bar hanging on the control body is removed to prevent sewing. Using this, any stitch over 12.7mm can be realized.

[Sequin Order]

The sequin command must have an optional sequin device, and when this command is issued, one sequin is supplied.

In other words, the sequin is supplied before sewing, and it is an order to sew together.

[Option device of embroidery machine]

An optional device of the embroidery machine may be a sequin supply device, a bead supply device, etc. In FIG. 1, a sequin supply device is illustrated. The sequin feeder is attached to the head of the embroidery machine.

However, in the past, it is impossible to work unless the embroidery machine is upgraded.

Therefore, users of the embroidery machine must change the machine itself in order to use the newly developed option devices (sequin feeder or bead feeder, etc.). The 20 head embroidery machine costs more than 40 million won, which is a very heavy burden for users. It is like a situation in which when a car had no navigation, after the navigation was developed, the car had to be changed to use the navigation.

Korean Patent Publication No. 10-2017-0136659 (released on December 12, 2017) Korean Registered Patent No. 10-1568384 (registered on November 5, 2015) Korean Registered Patent No. 10-0973558 (registered on July 27, 2010)

The present invention has been developed to solve the problems as described above, and the object of the present invention is to add a desired option device without changing the embroidery machine by determining the jump signal using the jump function existing in the embroidery machine and giving a command to the corresponding device. It is intended to provide a method for discriminating jump stitches in a new configuration that can be mounted and used.

The sensor is configured to include a mechanical encoder sensor, a needle bar position sensor and a trimming sensor, and is characterized in that the signal of the mechanical encoder sensor, a needle bar position sensor and a trimmer sensor is input to the CPU.

The embroidery machine is provided with a plurality of head portions having a plurality of needle bars, the head portions are provided with individual CPUs, and the CPU 20 is configured to input a jump recognition synchronization signal to the individual CPUs.

When the jump recognition synchronization signal from the CPU 20 is input to the individual CPUs provided in the head unit, the option device is configured to operate.

It characterized in that it is configured to detect the jump signal by detecting the current of the jump solenoid or jump motor when the jump recognition synchronization signal is received from the CPU 20.

The jump solenoid or the jump motor is characterized in that attached to the head of the embroidery machine.

According to the present invention, by using the jump function existing in the embroidery machine to determine the jump signal and give a command to the corresponding device, there is an effect that enables the operation using the embroidery machine without upgrading from the embroidery machine maker, and newly developed embroidery users Since there is no need to change the machine itself to use the optional equipment (sequin feeder or bead feeder), it has the effect of reducing the considerable cost burden to the user. For example, a 20 head embroidery machine has a price of 40 million won or more, but according to the present invention, there is no need to change the embroidery machine of 40 million won or more, thereby reducing the considerable cost burden to the user.

These terms are only for distinguishing the component from other components, and the nature, order, or order of the component is not limited by the term. When a component is described as being "connected", "coupled" or "connected" to another component, that component may be directly connected to or connected to the other component, but another component between each component It should be understood that may be "connected", "coupled" or "connected"

In addition, specific structures or functional descriptions in the present invention are exemplified for the purpose of explaining an embodiment according to the concept of the present invention, and the embodiments according to the concept of the present invention can be implemented in various forms and can be applied to the present specification or application It should not be construed as being limited to the embodiments described in.

Referring to the drawings, the embroidery machine jump stitch discrimination method according to the present invention includes inputting a sensing signal to the CPU 20 from the sensor of the embroidery machine, inputting a signal to the CPU 20 from the setting device, and the CPU ( 20) generating a synchronization signal.

It is necessary to read the signals of various sensors mounted on the embroidery machine and discriminate them. Thus, as shown in Figure 2, the center is provided with a CPU (20) (control unit) capable of discriminating the signals of various sensors in the embroidery machine, and receives a machine encoder signal, a needle bar position signal, and a trimming sensor signal. In the step of inputting the sensing signals of the sensors to the CPU 20, a machine encoder signal, a needle bar position signal, and a trimming sensor signal are input. The sensor provided in the embroidery machine may include a machine encoder sensor, a needle bar position sensor, and a trimming sensor, and is configured to input signals from the machine encoder sensor, a needle bar position sensor, and a trimmer sensor to the CPU 20.

In addition, the number of heads and the number of needle bars per head are set in the machine (embroidery) using the setting device of FIG. 2, and the needle bar to use the optional device is set. The optional device means various devices such as a sequin feeder or a bead feeder, and the number of heads and the number of needle bars per head provided to the embroidery machine from the setting device in the step of inputting a signal to the CPU 20 in the setting device. And set the needle bar to use an optional device such as the sequin feeder.

The present invention includes receiving a signal input from a setting device and a signal from a sensor mounted on the embroidery machine, and generating a jump signal for embroidery embroidery by the CPU 20. The CPU 20 receives a sensing signal from the machine encoder sensor, a needle bar position sensor, and a trimmer sensor and a signal input from a setting device to generate a jump recognition synchronization signal.

At this time, the embroidery machine is provided with a plurality of head portions having a plurality of needle bars, and the head portions are provided with individual CPUs 120, respectively, so that the jump recognition synchronization signal from the CPU 20 is provided to the individual CPUs 120. Will be entered. As shown in FIG. 2, if the number of heads is N, the jump recognition synchronization signal is input from the CPU 20 to each of the individual CPUs 120 provided in the N heads.

When the current needle bar position and the set needle bar are the same based on the sensing signal from the mechanical encoder sensor, the needle bar position sensor and the trimming sensor and the signal input from the setting device, and the machine encoder angle becomes the jump start angle (shown in FIG. 3). The jump recognition synchronization signal is generated. Each head unit has a separate CPU 120, and when a jump recognition synchronization signal is received, it is possible to determine whether it is a jump signal by sensing the current of the jump solenoid or jump motor. When the jump signal of the embroidery machine is generated in the jump recognition synchronization signal, it is determined as a jump signal. When it is determined by the jump signal, an optional device such as a sequin supply device (shown in Fig. 1) is activated.

The jump signal (jump command) is a function that prevents stitching at the corresponding immersion (the position where the stitch is entered). It does not sew by operating the solenoid or motor to release the needle bar hanging on the control body.

Based on the sensing signals from the mechanical encoder sensor, needle bar position sensor, and trimming sensor and the input signal from the setting device, a jump recognition synchronization signal is generated when the current needle bar position and the set needle bar are the same and the machine encoder angle reaches the jump start angle. .

Another reason for the jump operation is when the corresponding head of the embroidery machine is turned off. At this time, the jump will be activated throughout the machine operation. When a jump signal is issued from a machine (embroidery), the jump will work in situations such as when the head stops working on the embroidery machine, or if the head is broken and the head that does not have a thread break should not be sewn. This is because it should not come down and should not be recognized as a jump signal. For example, when the corresponding head is turned OFF in the embroidery machine, the jump signal occurs throughout the operation of the embroidery machine, but when the corresponding head of the embroidery machine is OFF, the jump signal is not recognized as a jump recognition synchronization signal. Figure 4 shows the jump signal when the normal jump and the jump signal when the head is OFF. As such, when the needle should not be lowered, such as when the head is OFF, the jump signal is determined as a jump signal when the head is off, so that the needle of the head is determined. This is to prevent stitching.

Hereinafter, an embodiment of the embroidery machine jump stitch discrimination method of the present invention will be described.

[Example]

This is the case of making an embroidery with the pattern shown in FIG. 4. Figure 1 shows an embodiment using a sequin feeder as an optional device.

First, embroidered data is made to make an embroidered object as shown in FIG. 4. Embroidery data can be created by the user using a design creation program. The design code configuration in the embodiment of the present invention is shown in FIG. 10.

The jump signal is a signal generated by the embroidery machine. The needle movement represents the actual needle movement provided on the head of the embroidery machine. As shown in Fig. 11, the needle is not lowered by the jump operation at the second and sixth needles, so that sewing is not made on the second and sixth needles in the embroidery. The jump recognition synchronization signal is a signal generated by the CPU 20 (manufactured controller) and is sent to the jump current checking device of each head. At this time, the individual CPU 120 of the corresponding head may be configured to be provided in the jump current checking device. The synchronization signal is input from the CPU 20 to the individual CPU 120 of the corresponding head. In FIG. 11, a jump recognition synchronization signal is input from the CPU 20 to the individual CPU 120 of the corresponding head, and the jump signal is the second stitch. It is shown that the sewing is not made on the 2nd and 6th stitches of the embroidery by being input at the 6th stitch.

The output of the option device checks the jump recognition synchronous signal and jump current at each head, and outputs the output of the option device when the jump current is confirmed in the jump recognition synchronous signal. The optional device may be, for example, a sequin supply device. The sequin supply device (sequin device) receives a signal in which the jump current is confirmed in the jump recognition synchronization signal and pushes the sequin into a needle bar. When you come down, you will sew. In Fig. 11, the second and sixth needles, where the output of the optional device is made, show the state in which the needle does not come down and push the sequin into one needle with the needle in the state where the needle is stopped, and the next needle (ie, 3) When the needle bar descends from the needle and the 7th needle), it is configured to sew.

Therefore, using this method, it is possible to determine the jump signal and easily attach a desired option device (for example, a sequin). It is easy to attach optional devices such as sequins to embroidery.

On the other hand, another reason that the jump recognition synchronization signal is required is to prevent the stitch from being made when it is not to be sewn by preventing it from being recognized as a jump signal even when the jump signal from the machine (embroidery) is issued.

When the head of the embroidery machine is turned off, a jump signal is generated throughout the operation of the embroidery machine, such as when the needle with the broken thread is retracted among several needles of the embroidery machine and the needle with no broken thread should not be sewn. However, when the head is turned off as described above, a jump signal occurs in a part other than the jump sync signal, for example, when thread break occurs and the needle is retracted and the needle that does not have thread break should not be sewn. It is determined that it is, and the output signal to the optional device is not transmitted, and the sewing is not made at the same time. When it is determined that a jump signal is generated in a portion other than the jump synchronization signal, the jump solenoid or motor mounted on the head is operated so that the needle does not lock. See FIG. 7.

When a jump signal occurs in a part other than the jump recognition synchronization signal, the CPU of each head part has a jump, but it is not recognized as a jump by a jump code. As described above, a jump signal is generated at a portion other than the sync signal, so that a jump occurs in the individual CPUs 120 of each head, but is not recognized as a jump by a jump code (jump sync signal), and thus the sewing of the head is stopped. . For this reason, a jump recognition synchronization signal is required.

In the above, specific examples of the present invention have been described above. However, the spirit and scope of the present invention is not limited to these specific embodiments, and various modifications and variations are possible within a range that does not change the gist of the present invention. Anyone who has it will understand it.

Therefore, the above-described embodiments are provided to fully inform the person of ordinary skill in the art to which the present invention pertains, the scope of the invention, and should be understood as illustrative in all respects and not restrictive. The invention is only defined by the scope of the claims.
