DETAILED DESCRIPTION OF THE INVENTION [Industrial applications]

The present invention relates to a computer embroidery sewing machine, and more particularly to a sewing machine provided with a pattern data switching device.

2. Description of the Related Art

Conventionally, when performing single-color embroidery with multi-color embroidery data on a computer embroidery sewing machine, the stitching portion that represents the main shape of the contour and embroidery pattern and the filling portion that fills the area between the stitching portions all have the same color. Therefore, the embroidery pattern has no meaning as a pattern, and the embroidery time required for the embroidery pattern takes a long time, which is a practical problem.

Means for Solving the Problems and Effects of the Invention

According to the present invention, in a computer embroidery sewing machine, a plurality of embroidery pattern data stored in an embroidery data storage device are each composed of fill-in data and trimming data, and the embroidery pattern selected by the pattern selection device is color-changed. When the mode with color change is specified by the operation of the switching means, all of these data become valid, and when the mode without color change is specified, only the trimming data becomes valid. According to the present invention, a beautiful embroidery pattern with multiple colors can be formed in the mode with color change, and only the trimming data is used in the mode without color change. There is an effect that a practical embroidery pattern can be formed in a short time.

【Example】

Hereinafter, the present invention will be described with reference to examples. First, the schematic configuration of the control circuit of the computer sewing machine will be described with reference to FIG. In the figure, an arithmetic unit 4 is a device that controls the entire control circuit. The pattern data storage device 5 stores a plurality of embroidery pattern data. Each embroidery pattern data is composed of fill-out data and trimming data as described later. The display device 7 displays necessary instructions at the time of selecting the embroidery pattern and after the selection. The pattern selecting device 1 can select a desired sewing pattern from the embroidery patterns stored in the pattern data storage device 5 while watching the display device 7 by the operation. The color change key 2 is a key that is operated when an embroidery pattern is selected, and switches between the presence / absence of color change of the selected embroidery pattern. That is, when the color change key 2 is operated, the color change flag that has been cleared when the power is turned on is set, and the mode is set to the mode with color change. If the key is not operated, the mode without color change is set. The pattern forming device 6 performs X-axis, Y-axis based on needle bar, shuttle, and embroidery pattern data driven and controlled by a sewing machine motor.
This is an apparatus that includes an embroidery frame drive unit that is driven and controlled by a shaft driving stepping motor, and forms an embroidery pattern on a work cloth set in the embroidery frame. The start / stop key 3 is an operation key for alternately driving and stopping the pattern forming device 7 by the operation. Next, the configuration of the embroidery pattern data will be described with reference to the memory map of FIG. The example shown in the figure shows a case where each of the filling data group and the trimming data group is a plurality of blocks (two blocks each). The embroidery pattern data is arranged as a color change block in the mode with color change, in the order of a color data block (color data I, color data II) and a frame data group block (frame data I, frame data II). Has a stop code and an end code added to the last data group block. When a stop code is read during execution of embroidery by a control program described later, the color change flag is referred to. In a mode in which color change is performed by operating the color change key 2, the color change flag is set. Stops once, and the upper thread can be set to the thread of the designated color. In the mode without color change, among the embroidery pattern data arranged in the order of the filling data group block and the trimming data group block as described above, only the trimming data group block is valid, and the filling data group block is invalid. Also, if a stop code is read during embroidery by the enabled trimming data group block, the color change flag is referenced, and in the mode without color change, the color change flag is cleared and ignored. The sewing machine continues to embroider the next block without stopping. Display screen Next, the display screen will be described with reference to FIGS. After the power is turned on and the embroidery mode is selected by the screen key of the display device 7, when the pattern switching key 11 of the screen function key section 10 is operated, a plurality of pattern displays for selectable embroidery patterns are switched to the pattern display section 20. The first (the left end of the pattern display unit 20) of the plurality of pattern displays of the pattern display unit 20 is the selected pattern display unit.
Appears on 21. When a pattern display of a pattern to be selected from a plurality of pattern displays on the pattern display unit 20 is pressed as a screen key, a pattern display for the pattern is displayed on the selected pattern display unit 21 and an embroidery pattern is selected. Among the embroidery patterns, a color change key 12 is displayed on the function key unit 10, and there are a type in which a mode with color change can be designated and a type in which the mode cannot be specified (embroidery pattern data consists only of trimming data). 1) Mode with color change Select an embroidery pattern for which a mode with color change can be specified, and specify a mode with color change using the color change key 12, and as shown in FIG. The selected pattern is displayed, the sewing block display of the selected pattern is displayed on the sewing block display section 23, the number indicating the sewing order of the sewing block is displayed on the sewing order display section 22, and the thread color of the sewing block is displayed. Is displayed in the color designation section 24. 2) No color change mode Select the embroidery pattern, and the color change key is not displayed on the function key section 10, and the color change key 12 is operated for the color change mode that cannot be specified and the color change mode that can be specified. When the mode without color change is selected without performing the operation, the selected pattern is displayed on the selected pattern display section 21 as shown in FIG. -Control operation The control operation of the embroidery sewing machine will be described with reference to FIG. In the figure, Sn (n = 1, 2, 3,...) Indicates each processing step of the control operation. S1 The embroidery pattern is selected by the pattern selection device 1. Prior to this, the color change flag is cleared when the power is turned on. Check the operation state of the S2 key. If there is a key operation and the color change key 2 is operated, set the color change flag cleared when the power is turned on.
