Detailed ways

The present invention will now be described in detail based on the embodiment shown in the drawings.

Fig. 1 is an embodiment of the sewing device (hereinafter referred to as sewing machine) of the present invention. As shown in the figure, the needle 13 of the sewing machine 1 is fixed by the needle bar 12, and the needle 13 moves up and down after the power supply 4 is switched on. to. Along with the needle movement, the cloth feeding device 17 feeds the cloth according to a predetermined cloth feeding pitch (sewing pitch) for sewing. The sewing operation is controlled by the control box 3 of the control device for sewing control corresponding to the action of the foot pedal 5 according to various commands, sewing parameters and other control data. The control box 3 is provided with a setting switch 9 for setting sewing parameters and the like, and a setting display 10 for displaying a set value.

In addition, the sewing machine 1 is equipped with an operation panel 6, which is provided with a display device monitor 6a composed of liquid crystal, CRT, etc., and as a setting device, a selection tool, or an input tool for performing various settings, selections, or inputs. The setting and selection button 6b, the input button 6c and the mouse (not shown). While displaying preset or input information on the monitor 6a, various image data are displayed on the monitor 6a as described below.

Fig. 2 has shown the block structure of the control device in the sewing machine control box 3. The entire sewing operation is controlled by the CPU (control device) 22 . CPU22 according to setting switch 9 and operating panel 6 set setting value and input value, and according to various sewing parameters and sewing data stored in non-volatile memory (storage device) 25, then according to detecting pedal The state of the detector 21 of the motion of the plate 5 is controlled by the motor control device 24 to drive the sewing machine motor 2, or to drive various driving mechanisms 23 to control the sewing operation. In addition, the display control circuit 26 displays and controls the image data stored in the nonvolatile memory 25 on the monitor 6a.

As shown in FIG. 3 , under various sewing conditions, the image data of the object to be sewn is stored in the nonvolatile memory 25 when sewing is performed with various values of the sewing parameters changed. Sewing conditions refer to cloth, thread, etc., as shown in Figure 4, when sewing buttons and winding knots, the sewing parameters refer to the shape of the button, button shape and sewing shape, buttonhole interval (longitudinal), buttonhole Interval (horizontal), number of button sewing stitches, amount of blind seam, height of wrapping knot, width of wrapping knot, etc. Among them, the value (item) of the shape of the button includes blind stitching, full stitching, and blind stitching; the value (item) of the button shape and sewing shape includes four eyes, two eyes, and a pin-shaped button with a handle. The values of other sewing parameters are numerical values. In the nonvolatile memory 25, the image data of the sewing product when sewing is performed while changing the sewing conditions and values of the sewing parameters corresponding to each sewing parameter is stored.

For example, under the sewing conditions of cloth (1) and thread (1), the sewing is performed when the sewing shape is A11, the button shape is B11, ... the sewing knot height is I11. The image data P11 of the object is stored in the nonvolatile memory 25. Similarly, under the same conditions, image data P12, ... P1n of the object to be sewn when sewing is performed when each sewing parameter value is A12, ... I12; ...; A1n, ... I1n are stored.

For such image data, the sewing condition is changed to cloth (2), thread (2), . . . cloth (m), thread (n). Image data P21, P22, ... P2n; ...; Pm1, Pm2, ... Pmn are stored under various sewing conditions, especially when sewing is performed while changing the above sewing parameter values.

These image data are real images of the object to be sewn, which are photos taken by a digital camera or sample images obtained by scanning. Both are realistic image data in which different sewing parameter values can be recognized.

In addition, although each sewing parameter value belonging to each image data does not have to be different, each image has a difference in at least one sewing parameter value, so each image is an image that is different from each other.

Here, regarding the sewing device having such a configuration, the flow of setting the sewing parameters will be described with reference to FIG. 5 .

When the sewing machine user turns on the power source 4 (step 1), as shown in Fig. 6, an initial screen is displayed on the monitor 6a (step 2). At this time, if you want to set the sewing parameters, you can choose whether to automatically set the sewing parameter values through the sample image data or to set the sewing parameter values through manual input (step 3).

In the case of selecting the button "set sewing parameters through the sewing sample image list", since the sewing condition setting screen shown in Figure 7 is displayed, the user can set the required sewing conditions, such as sewing Set the type of cloth and thread, etc. (step 4). After setting the conditions, when the "OK" button is pressed (step 5), a list of sample images used under the set sewing conditions is read from the nonvolatile memory 25 . For example, under the conditions of cloth (1), thread (1), sample images P11, P12, ... P1n are read out and displayed by a monitor (step 6). This state is shown in FIG. 8 .

At this time, for example, the sample image P12 is the desired content, and the user can select it and operate the "OK" button (step 7). Each sewing parameter value A12, B12, . In addition, as shown in FIG. 9 , the set sewing parameter values are displayed on the monitor 6 a together with icons. Here, the meanings of the icons are as shown in FIG. 4 . The buttons, buttons, and sewing shapes are icons corresponding to A12 and B12, and the others are default icons. The above-mentioned readout parameter values related to the icon are displayed. Therefore, the user can know what value the sewing parameter is set to. Also, the automatically set sewing data values are stored in other areas of the nonvolatile memory 25, and the CPU 22 controls sewing based on these sewing parameters.

When selecting and displaying sample images under other sewing conditions, as in the above case, if cloth (m) and thread (m) are selected, sample images Pm1, . . . Pmn are read out and displayed. For example, if the sample image Pmn is selected, the respective sewing parameter values Amn, ... Imn corresponding to the image are displayed on the monitor, and at the same time, the sewing parameter values for the sewing article are automatically set to these values.

In this way, the user views the sample images of the sewing item displayed on the monitor at a glance, and selects only the sewing sample he wants from among them. Since the values of the respective sewing parameters used for this sewing are automatically set, it is easy to set the sewing parameters, and at the same time, desired sewing effects can be easily achieved. In this case, since the sewing sample images of the objects to be sewn under various sewing conditions are stored and displayed in a list for each sewing condition, it is easy to search for the objects to be sewn that meet the sewing conditions.

On the one hand, in step 3, if select " set sewing parameter by manual input " as shown in Figure 6, because the sewing parameter input screen as shown in Figure 9 is displayed, so can input sewing parameter value (step 10). The input of the shape 30 of the button, the button shape and the sewing shape 31 is carried out by the setting button 6b, and other sewing parameter values (can be input at each numerical value among Fig. 9 ) are carried out by the input button 6c.

After the input is completed, if you want to know the sewing effect of the input parameter value, press the "confirm" switch to start searching whether the same content as the input value of the sewing parameter is stored in the non-volatile memory. This case is indicated from the confirmation branch of step 11. First, move the pointer P in Fig. 3 to the uppermost memory area (step 12), read out each sewing parameter pointed by the pointer, and check whether it is the same as the input sewing parameter value (step 13). If they are the same, the image of the sample pointed by the pointer is read out and displayed on the monitor 6a (step 14). This state is shown in FIG. 10 .

On the other hand, if they fail to be consistent, then give the pointer an increment (step 15), read out the next sewing parameter value and compare until it is consistent. When the pointer exceeds the maximum value (P>Pmax) shown in FIG. 3 and there is still no consistent content (step 16), it is searched whether there is similar content. For this reason, point the pointer to the initial position again (step 17), and check whether the initial N (for example N is 7) sewing parameter values are consistent (step 18). If they match, the sample image pointed by the pointer is displayed on the monitor 6a as an approximate image (step 19). If there is no consistent content, then proceed in the same way as the above case, that is, repeat this operation until the pointer exceeds the maximum value (step 20, step 21). Finally, if no content consistent with the initial N parameter values is retrieved, no consistent and similar sample images are displayed (step 22).

In this way, since the sewing state expected from the input sewing parameters is displayed, the user can confirm the sewing effect of the sewing parameters input by the user without trial sewing.

If "sewing" is selected in step 11, sewing is performed (step 30). After sewing is finished (step 31), the screen of Fig. 9 is changed again (step 32). Observe the object to be sewn, if the expected sewing effect cannot be realized (step 33), then set the sewing condition (step 35) by selecting "comparison" (step 34) to display the sewing condition setting screen shown in Figure 7 . If the "OK" button is selected (step 36), the sample image (step 37, Figure 8) under the set sewing conditions is displayed, so the required sample image can be selected (step 38), and will be combined with The sewing parameter value corresponding to the sample image is read out from the non-volatile memory 25, and it is compared with the sewing parameter value set in the above sewing process (the sewing parameter value input in step 10), and the The difference is displayed on the monitor 6a. This state is represented by FIG. 11 , where the differences between the sewing parameter input values at the upper part 32 and the sewing parameter values at the sample image at the lower part 33 are displayed. Therefore, the user can achieve the expected sewing effect by inputting these sewing parameters again.

In this way, when the user fails to achieve a good sewing effect with the sewing parameters input by himself, he can easily confirm which sewing parameter value the desired sewing effect is different from, thereby making the correction operation simple.

As shown in FIG. 12 , the selected sample image, the top image data 40 observed from above, the side image data 41 observed from the side, the image data 42 observed from obliquely above, etc. can also be stored in the non-volatile In the permanent memory 25, it is displayed in sequence whenever a predetermined time has passed. In this case, since the sewing sample images of the states viewed from various directions can be displayed, the displayed sewing state can be grasped more specifically.

As shown in Figure 13, also can the sewing status image 50-54 of each process in the sewing process (button making and thread winding process) be stored in the non-volatile memory 25, and according to each process these The image is displayed on the monitor 6a. Thus, the user can easily grasp the sewing status of each process, thereby making sewing more efficient.

As explained above, since the present invention can automatically set the sewing parameter values that can achieve the sewing effect of the sample image shown, the setting of the sewing parameters for the desired sewing effect becomes simple.

According to the present invention, even if manual input is used, since the expected sewing state according to the input sewing parameters can be displayed, the user can confirm what kind of sewing effect the input sewing parameters will have without trial sewing. In addition, when a good sewing effect cannot be achieved by the input sewing parameters, the user can easily confirm which sewing parameter value is different from the desired sewing effect, thereby simplifying the correction of the sewing parameter value.
