Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an embroidery device, and in particular, it is capable of inking embroidery patterns on cloth attached to an embroidery frame based on embroidery data in addition to normal embroidery stitches. The present invention relates to an embroidery device made of such a material.

(Prior art and problems to be solved by the invention) The stitch forming mechanism and the embroidery frame to which the fabric is attached are moved relative to each other based on the embroidery data, and embroidery is performed while forming stitches on the fabric. In conventional embroidery devices, the embroidery medium requires waterproofness, and the waterproofness is impaired by the needle hole caused by the embroidery stitch, and the function of the material is damaged by the embroidery stitching because the fabric is double layered, such as in pocket areas. There is a problem in that normal embroidery cannot be performed depending on the embroidery medium, such as objects.

(Means for Solving the Problems and Effects of the Invention) The present invention provides an embroidery device that is capable of not only normal embroidery but also inking embroidery patterns on cloth attached to an embroidery frame based on embroidery data. 0 (to do,
According to the present invention, an embroidery pattern can be written on an embroidery medium based on embroidery data in ink on a medium that cannot be embroidered with normal embroidery, and the ink can be written using foaming ink, fluorescent ink, etc. It is possible to express the unique texture of ink by using the embroidery frame.Furthermore, a film sheet is pasted onto the base fabric attached to the embroidery frame, the pattern is inverted and ink is written on the film sheet, and this is used as a master plate to be attached to the embroidery frame. This has the effect of greatly expanding the range of applications of the embroidery device, such as making it possible to transfer images onto embroidery media that cannot be attached using an iron or the like.

(Example) The present invention will be explained below with reference to Examples.

In FIG. 2, an embroidery device 1 drives a sewing machine 2 for forming stitches, an XY mechanism 4 for moving an embroidery frame 3 to which cloth is attached relative to the needle drop of the sewing machine 2, and this mechanism. It has an XY motor 5.

A floppy disk (FD) stores embroidery data for a plurality of sewing patterns. When a floppy disk (FD) is inserted into the floppy disk drive (FDD) and a sewing pattern is selected by operating the keyboard (KEY), the selected sewing pattern is displayed on the display device (LCD) and the selected sewing pattern is The embroidery data for the pattern is written to a temporary storage device (RAM).

The embroidery data is calculated by a central processing unit (CPU) prior to the start of embroidery and during embroidery according to a program stored in a read-only storage device (ROM), and is sequentially developed into eaves data for each stitch.

When embroidery starts, the sewing machine motor 6 starts operating the sewing machine 2, and in synchronization with the signal from the upper shaft sensor 7, the drive circuit 8 of the XY motor 5 receives a control signal based on the developed store data. is input, and a drive pulse for the XY motor 5 is output from the drive circuit 8.

The control circuit 9 receives the same signal as the control signal and generates drive pulses intermittently while the embroidery frame 3 is being controlled. The ink writing attachment 1O consists of an ink supply section 11 and a printer head 12, and is detachably attached to the sewing section of the sewing machine 2 in the vicinity of the sewing section as shown in FIG. The control circuit 9 is connected to the control circuit 9. The ink supply section 11 stores ink therein and supplies the ink to the printer head 12. The printer head 12 is based on the same operating principle as the printer head of an inkjet printer.
A Glude type printer head that ejects ink by deformation of a piezoelectric element or a bubble type printer head that ejects ink by the bubbling pressure in the ink caused by intermittent heating of a heating resistor element can be used, and its lower end 12a is attached to the embroidery frame 3. The embroidery frame 3 is placed close to and facing the fabric W, and intermittently ejects ink toward the fabric W while the embroidery frame 3 is being driven and controlled by intermittent drive pulses from the control circuit 9. .

As is clear from the above, the sewing machine needle is removed from the needle bar 14 of the sewing machine 2, and the ink writing attachment is attached to the sewing machine 2! 0 and write ink, the needle drop points and the line connecting these points based on the expanded Eanten data will be inked on the cloth W in a form similar to the needle drop points and the crossing threads between them during embroidery. It is written.

Therefore, this ink writing is effective for embroidery media that cannot be embroidered with normal embroidery, and it is also possible to use effervescent ink, fluorescent ink, etc. in ink writing to express the unique texture of the ink. A film sheet is attached to the base fabric attached to the embroidery frame, a reversed pattern is written in ink on the film sheet, and this is used as a master plate to be transferred with an iron or the like onto a medium to be embroidered that cannot be attached to the embroidery frame. This greatly expands the range of applications for embroidery equipment.

(Effects) As described above, according to the present invention, an embroidery pattern can be written in ink on a medium that cannot be embroidered with normal embroidery based on embroidery data. By using fluorescent ink, fluorescent ink, etc., it is possible to express the unique texture of the ink.Furthermore, by pasting a film sheet on the base fabric attached to the embroidery hoop, and writing ink with an inverted pattern on the film sheet, This has the remarkable effect of greatly expanding the range of applications of the embroidery device, such as by making it possible to use the original as an embroidery frame to transfer it onto an embroidery medium that cannot be attached to an embroidery frame using an iron or the like.

Claims (1)

[Claims] In an embroidery device that performs embroidery while forming stitches on cloth by relatively moving a stitch forming mechanism and an embroidery frame to which cloth is attached based on embroidery data, the embroidery frame is driven in XY through an XY mechanism. While the embroidery frame is being driven in response to a control signal to the XY motor drive circuit, a control circuit that generates intermittent drive pulses and a connector detachably attached to the sewing machine are connected to the control circuit. The ink writing attachment includes a printer head that intermittently ejects ink in response to intermittent drive pulses from the control circuit, and an ink supply section that supplies ink to the printer head. An embroidery device characterized in that it is configured to be able to write an embroidery pattern in ink on a cloth attached to an embroidery frame based on embroidery data.
