Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an embroidery sewing machine having an outer shell pattern sewing function and a data generating device.

[0002]

2. Description of the Related Art In a conventional embroidery sewing machine, stitch data for forming a pattern is produced in advance by a manufacturer, and the user selects and stitches the stitch data.

[0003]

However, with the widespread use of sewing machines capable of embroidery sewing, there is a growing need for users to embroider a pattern that suits their tastes. I could not meet the request. The present invention aims to solve the above-mentioned problems of the prior art.

[0004]

In order to achieve the above object, an embroidery sewing machine having an outer shell pattern sewing function of the present invention is provided with a means for providing data for forming a stitch corresponding to a predetermined pattern. , Means for providing information for arranging a plurality of the predetermined patterns continuously, means for adjusting a space between the plurality of patterns for arranging the predetermined patterns, and forming the seam Means for embroidering at a position based on information for arranging a predetermined pattern on the basis of data for
It is characterized by having. The means for giving the data for forming the stitch is usually a storage device and a reading device in which the stitch data is stored, but it may be an image sensor device for inputting an image or a pattern data creating device such as CAD. The pattern referred to here includes all figures, characters, symbols, lines, and the like. The means for giving information for arranging gives information representative of a loop-shaped outer shell line, and the means for sewing embroidery executes sewing so that a pattern is arranged along this line. To do. The space between the patterns is adjusted by the adjusting means according to the size and number of the selected patterns or the length (size) of the shell lines for the arrangement. The pattern may be arranged anywhere on the line, outside the line, inside the line, or a mixture of these. It is desirable that the length of the line for arranging the patterns and the number of sizes of the patterns can be changed so that the user can arbitrarily set them. The means for adjusting is adapted to adjust the pattern spacing in response to these changes. The above structure may be provided in the embroidery sewing machine itself,
It is also possible to form it as a single outer shell pattern sewing data generation device.

[0005]

Embodiments of the present invention will be described below with reference to the drawings. In FIG. 1, outer shell data providing means 1 provides data representing the outer shell. The outer shell data assigning means 1 is a memory that stores outer shell data, another data generating means, or the like, and is configured to assign the line data as shown in FIG. 5A, for example. In FIG. 5 (A), the outer shell is formed by lines such as a round shape, a heart shape, a shield shape, and a rhombus shape, and the user can arbitrarily select the outer shell. The data from the outer shell data giving means 1 is displayed on the display means 8 and inputted to the pattern arrangement adjusting means 6.

Similarly, the unit pattern data providing unit 2 provides data representing the unit pattern. The unit pattern data providing unit 2 is also a memory that stores the pattern data, another pattern data generating unit, or the like. The pattern data is as described above,
It includes figures, letters, symbols, etc., and in some cases, information about colors. In the example shown in FIG. 5B, a rhombus,
A unit pattern such as a circle, a star, an ellipse, a heart, and a triangle is facilitated, and the user can arbitrarily select these. The signal from the unit pattern data providing unit 2 is also sent to the display unit 8 for display and is also sent to the pattern arrangement adjusting unit 6. .

The outer shell selected by the outer shell data giving means 1 is set to a predetermined size as an initial value, but this size can be changed by the outer shell size setting means 3, The user can set any size. The size and number of the unit patterns selected by the unit pattern data providing unit 2 are also set to predetermined sizes and numbers, but can be changed by the unit pattern number setting unit 4 and the unit pattern size setting unit 5. It has become. The pattern arrangement adjusting unit 6 receives information from the outer shell data providing unit 1 and the unit pattern data providing unit 2 and a change command from the outer shell size setting unit 3, the unit pattern number setting unit 4, and the unit pattern size setting unit 5. The arrangement of the pattern is adjusted according to. For example, as shown in FIG. 6A, a circular outer shell line L and a triangular unit pattern M are selected, and the number of unit patterns M is eight.
In the case of individual pieces, they are normally arranged as shown in (A). Here, when the user operates the outer shell size setting means 3 to reduce the size of the outer shell line L to the outer shell line L ′ as shown in (B), the pattern arrangement adjusting means 6 changes the array position. The unit patterns M are adjusted so that the unit patterns M are arranged so as to overlap each other. In this way, the pattern arrangement adjusting means 6 always automatically arranges the appropriate unit patterns M, so that the size of the outer shell and the size and number of the patterns can be set to the user's favorite one. .

The pattern arrangement adjusting means 6 sends the pattern data from the unit pattern data applying means 2 whose arrangement has been adjusted to the seam forming means 7 and forms the seams there. Although the case where the patterns are arranged on the outer shell line L has been described with reference to FIG. 6, the unit pattern M is arranged inside the outer shell line L, the unit pattern M is arranged outside the outer shell line L, etc. Is possible. Also, these may be combined.

In FIG. 6, a plurality of one type of unit patterns M are arranged, but the present invention is not limited to this, and it is possible to dispose a plurality of types of unit patterns M. It is also possible to form a sentence using characters.

Further, although the direction of the unit pattern M is constant in FIG. 6, it is also possible to change the direction.

A signal from the pattern arrangement adjusting means 6 is inputted to the seam forming means 7 to display the selected unit pattern M along the selected outer shell line L and in an adjusted arrangement form. ing.

Although the outer shell line L represents a single line in the above description, it is possible to set an outer shell having a predetermined area by a plurality of lines, and a unit can be set in this outer shell. The pattern M may be arranged. With such a structure, it is possible to form a more varied embroidery pattern. Further, the unit pattern M may be configured to be able to be reversed in black and white.
