Abstract

PURPOSE:To enable the shape of pattern and sewing command to be confirmed by detecting a position of the sewing command previously inserted in sewing data and calculating an amount of idle feed to the position, according to the sewing data to linearly move a cloth holder to the command position in the sewing data. CONSTITUTION:When an operator inputs a desired sewing pattern through a pattern No. key on a keyboard 4, a control unit 3 causes sewing data of the specified sewing pattern to be read from a memory 1 and stored in a memory 2. Next, when the operator inputs a point he wants to confirm through the keyboard 4, the control unit 3 permits the memory 2 to store the inputted confirming command. Next, when the operator inputs feed advance or feed retreat through the key board 4, the control unit 3 judges whether the direction of confirming the shape of the sewing pattern is the sewing direction or returning direction to store an idle feed amount to the confirming command in the memory 2, and calculates according to the sewing pattern data, drives a drive unit 6, operates a pulse motors 8, 9 and moves a cloth holder directly to the confirming command position.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a sewing pattern shape confirmation device for confirming a previously selected pattern and the size of the pattern relative to the area before sewing.

[Conventional technology]

As is well known, when sewing a pattern with a sewing machine, the sewing pattern is selected based on the sewing pattern number, and the operator cannot visually see the pattern itself, and furthermore, there is no possibility that the selected pattern will enter the sewing area or not. Maybe I can't see it visually.

For this purpose, the entire sewing pattern is trial-sewn either by blank feed or by stitch-by-stitch feed to check whether the pattern and the pattern fit in the sewing area l or not.

[Problem to be solved by the invention]

However, in this conventional method of checking the shape of a pattern, it is necessary to test-sew the entire sewing pattern, which has the disadvantage of significantly reducing work efficiency.

Furthermore, all the sewing patterns must be trial-sewn, and various sewing commands (
For example, “sewing start command” “inflection point command”
- Since it is not possible to check each time stop command, thread trimming command, jump feed command, reversal point command 1, speed limit point command, etc., speed limit command, etc.) There are disadvantages in that it is not possible to confirm the sewing point where a command has been inserted, or to confirm that each pattern can be sewn correctly on the baseline when sewing multiple patterns.

The present invention improves on this point, and an object of the present invention is to provide a sewing pattern shape confirmation device that can efficiently confirm the shape of a pattern and also confirm sewing commands.

[Means for solving problems]

The present invention is characterized in that the sewing pattern shape confirmation device is configured to be able to confirm the sewing pattern at each sewing command position in the sewing pattern data or at each position of a desired number of stitches.

[Effect]

In addition, the shape of the sewing pattern can be checked for each desired number of stitches without the need to check the entire sewing pattern by empty feed, so the shape can be checked accurately and efficiently. It is also possible to easily confirm whether or not the sewing area is entered.

Furthermore, by checking the shape for each sewing command, you can check whether each of the multiple sewing patterns to be sewn in combination is correctly placed on the base line, and check where on the sewing shape the speed limit is applied. It is possible to easily match the sewing data with the sewing data.

〔Example〕

An embodiment of the present invention will be described based on the drawings.

FIG. 1 shows a bronch diagram of essential parts of an embodiment of the present invention.

In FIG. 1, ] indicates a memory in which pattern data is stored in advance. A memory 2 for storing read pattern data is connected to this memory 1.

This memory 2 is connected to a control section 3. The control section 3
A keyboard 4 and drive units 5 and 6 are connected to the keyboard 4 and drive units 5 and 6, respectively. A main motor 7 is connected to the drive unit 5, and a pulse motor 8 for the X coordinate and a pulse motor 9 for the Y coordinate are connected to the drive unit 6, respectively.

FIG. 2 shows a detailed view of the keyboard 4.

FIG. 3 shows a flowchart of one embodiment of the present invention.

〔motion〕

The characteristic operation of one embodiment of the present invention configured in this way will be explained.

The operator enters the desired sewing pattern by entering pattern N on the keyboard 4.
It is input using the o key, and the enlargement rate or reduction rate of the sewing pattern is set using the reduction key. At this time, it is also possible to input a combination of a plurality of sewing patterns to be sewn using the pattern number, key, and combination key.

The control section 3 reads out the sewing data of the specified sewing pattern from the memory 1 to the memory 2 and holds it therein, and when there is an instruction to enlarge or reduce the sewing data, the control section 3 calculates the enlarged or reduced sewing data of the sewing data and stores it in the memory 2. hold it.

Further, the operator confirms the specified sewing pattern and inputs one point using the keyboard 4.

In other words, the "sewing start command" inflection point command in the sewing pattern, the "-time stop command" and the "thread trimming command"
A command that requires confirmation is input from the keyboard 4, such as ``jump feed command'', ``reverse point command'', and ``speed limit point command''. The control unit 3 stores the input confirmation command in the memory 2 (block 20 in FIG. 3, hereinafter simply referred to as "block").

Furthermore, the operator inputs forward or backward feed from the keyboard 4 (block 21). The control unit 3 determines whether the shape confirmation direction of the sewing pattern is the sewing direction or the return direction in accordance with the feed direction instruction input, stores the jump feed amount up to the input confirmation command in the memory 2, and stores the sewing pattern data. According to the calculation result, the drive unit 6 is driven to operate the pulse motor 8.9, and the cloth presser is directly moved to the confirmation command position (block 23).

This allows you to easily check whether each of the multiple sewing patterns to be sewn in combination is correctly placed on the base line when the thread trimming point command is specified, and the sewing shape when the speed limit point command is specified. You can easily check where on the top the speed limit is applied, and you can easily match the sewing shape with the sewing pig.

If the operator wishes to confirm the shape of the sewing pattern for each desired number of stitches, the operator inputs the number of stitches from the keyboard 4 (block 20), and further inputs the sewing pattern confirmation direction as described above (block 21).

The control section 3 stores in the memory 2 the amount of jump feed in the confirmation direction according to the inputted number of stitches and calculates it according to the sewing pattern data (block 22), and drives the drive section 6 based on the result of this calculation. The pulse motor 8.9 is operated to directly move the cloth presser to the stitch number position (block 23).

As a result, the shape of the sewing pattern can be checked for each desired number of stitches, the shape can be checked accurately and efficiently, and it can also be easily checked whether the sewing pattern falls within the sewing area or not. I can do it.

〔effect〕

As described above, according to the present invention, when checking the shape of a sewing pattern, the sewing pattern can be checked for each sewing command position in the sewing pattern data or for each desired number of stitches.

Therefore, the shape of the sewing pattern can be checked for each desired number of stitches without the need to check the entire sewing pattern by empty feeding, so that the shape can be checked accurately and efficiently.
Moreover, it is also possible to easily check whether the sewing pattern falls within the sewing area.

Furthermore, by checking the shape of each sewing command, you can check whether each of the multiple sewing patterns to be sewn in combination is correctly placed on the baseline, and set speed limits based on the sewing shape! : It has excellent effects such as making it easy to check sewing shapes and sewing data.
