Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automatic multicolor embroidery sewing machine equipped with a converter for converting a needle number (or thread number) designation.

When making embroidered products, in order to diversify the product, even if the embroidery pattern is the same, it is possible to vary the product by making products with various color schemes. It is commonly practiced.

In an automatic multicolor embroidery sewing machine that has a plurality of needles and performs multicolor embroidery by threading threads of different colors onto the needles, embroidery data (program) is input into a memory using paper tape. In this data, colored threads are designated by needle numbers (designated thread numbers). Conventionally, if the designated thread number input into the memory is different from the colored thread set in the embroidery machine, it has been necessary to reset the thread to the same position as the input data. In other words, if the specified color input into the memory does not correspond to the color of the thread set on the sewing machine, the thread must be replaced manually so that the corresponding relationship is as specified. Nakatsuta. Each head has multiple needles,
In the case of a multi-needle, multi-head automatic multi-color embroidery machine with multiple heads driven in parallel, for example, a 13-head multi-color embroidery machine with 5 to 7 colors of thread,
It took more than an hour to change all the colors, and changing the threads was a very tedious task.

In order to eliminate these drawbacks of the conventional sewing machine, the present invention is characterized in that the data (specified needle) in the memory can be converted by key operation without changing the thread. be.

In the program (data) currently input into the memory of the embroidery machine, for example, the needle numbers, , , red, orange, yellow, green, etc.
If you want to embroider with a color scheme that corresponds to the color blue, the thread colors already set on the sewing machine are blue, green, orange, red, and yellow, corresponding to the needle numbers, ,, (thread number,
, , ). Conventionally, the thread is changed, but according to the present invention, this is done by changing the needle number.

Figure 1 shows the conversion procedure for an input program.The color of the thread that you want to correspond to the needle number in the input program data is the same as the color of the thread currently attached to the needle of the embroidery sewing machine. When this is the case, that is, when the desired colored thread (thread number) is threaded onto the needle number designated by the program, there is no need for replacement. If a thread of a different color than the desired color is attached to the needle number specified in the program, press the necessary key operation on the keyboard (program mode key, color operation key, etc.) to select the color number. Displays the standard specification display. That is, it displays which thread number and colored thread are currently attached to which needle number in the machine. Next, while viewing this display, use the color number (thread number) setting key to set the needle number to be converted. As in the example above, the needle number of the program,
, , , respectively, if you want to make the green threads of red, orange, yellow, green, and blue correspond to each other, you can check the relationship between the color of the needle of the current embroidery machine and the thread attached to it by looking at the display (color (are indicated by thread numbers), find the needle number where the desired color thread (thread number) is attached, and place it using the number keys provided corresponding to each needle number. Count. When the number has been set for each needle number, it is input to the conversion section.

FIG. 2 shows a block diagram of an embodiment of the present invention.
The conversion information set by is input into the fixed register 4 of the conversion section 3. The fixed register 4 determines the conversion characteristics of the converter 5.

In this way, embroidery is executed after the input of conversion information to the conversion section 3 using the color number setting key 2 is completed. In the execution, the needle number part of the command (data) of the program is converted by the conversion section 3. That is, the instruction read from the memory 6 to the memory register 7 has its needle number portion passed through the converter 5 and placed into the instruction register 8, and the remaining portion of the instruction is placed directly into the instruction register.

As explained above, according to the present invention, even if a thread different from the input data (program) is set in the embroidery sewing machine, it is possible to convert it to the same thread (desired thread) as the input data by key operation. This eliminates the need to reset the thread as was the case in the past. In the case of the 13-head multicolor embroidery sewing machine illustrated above, it took more than an hour to manually set the thread, but according to the present invention, it took more than an hour to set the thread manually.
It takes about 20 to 30 seconds to complete the process, so the hassle of resetting the thread as in the past is completely eliminated. Also,
Since threads can be specified arbitrarily, it has become extremely easy to perform various embroideries with different color patterns by changing the color combination in order to create a variety of products.
