Examples of sewing machines that perform setting input using such an operation panel include an edge stitch sewing machine and an eyelet perforation sewing machine, but all the figures displayed on these operation panels are set with the fabric set on the sewing machine. In general, the display is performed in the direction as seen from above by the operator.
For example, in the case of eyelet-punched sewing machines, when the fabric is worn as clothing, the back side of the sewing material that is the back side is set up and the fabric is set and sewn. After confirming the completed state of a pair of buttonhole stitches formed on both sides of the hole, when trying to correct the data on the operation panel, the buttonhole stitches formed on the work piece are arranged. In the figure displayed on the panel, the left-right direction is reversed across the eyelet button hole. For example, if the surface illustrated in FIG. 14 is the back surface of the fabric, a figure viewed from the A direction is displayed on the operation panel, but the surface of the fabric is viewed from the B direction. For this reason, for example, when looking at the surface of the fabric and trying to correct the clearance gap between the female cut as the eyelet button hole and the seam on the right side of the cut, the gap on the left side of the cut is corrected on the operation panel display. Had to enter.
In addition, in an automatic ball edge sewing machine, the surface of the body cloth is turned up and the cloth is set from the top, and sewing is performed, but on the surface side of the sewn body cloth, cover the pocket hole from both sides. The pocket hole cannot be seen from the surface of the finished fabric because the drapery is standing up. For example, the formation position of a pair of edge seams formed on both sides of the center cut (straight cut) of the pocket hole In addition, in order to confirm the cutting positions (corner cut positions) of the left and right corner knives, it is necessary to turn the fabric over and confirm. At that time, the left and right sides are reversed by the arrangement of the corner cuts and the bead stitches formed on the sewing object and the figure on the operation panel.
As described above, the sewing machine that performs setting input using the operation panel does not always display a graphic indicating the disposition of the stitches and the stitches to be seen when viewed from the direction in which the operator confirms. If they do not match, there is a problem that the right and left may be mistaken when inputting the settings.

  An object of the present invention is to suppress erroneous input of various parameters related to cuts and seams applied to a workpiece.

According to the first aspect of the present invention, there is provided a seam forming means for forming a pair of opposed seams arranged opposite to each other across a straight line along the cloth feed direction of the workpiece, or a pair of opposed cuts arranged opposed to each other across the straight line.

Corresponding part switching means for switching by instruction input; and identification display means for displaying the current switching state by the corresponding part switching means in an identifiable manner , wherein the parameter setting means is configured to display each of the opposing stitches displayed on the display unit. Alternatively, each of the opposing cuts is made to correspond to switching of corresponding parts by the corresponding part switching means, and the straight line is sandwiched between them. To the rolling, characterized in that it displays.

The invention according to claim 2 has the same configuration as that of the invention according to claim 1, and the parameter setting means sets the arrangement and function assignment of the part designating means and the parameter input means to the corresponding part. It is characterized in that it is inverted corresponding to the switching of the corresponding part by the switching means .

According to the first aspect of the present invention, each setting part represented by the graphic displayed on the display unit is selected by the part specifying means, and the setting value of the sewing parameter is set and inputted by the parameter input means for the selected setting part. .
At this time, the parameter setting means switches by instruction input whether each set site shown in the graphic displayed on the display unit corresponds to a site viewed from the front surface or a site viewed from the back surface. be able to. Further, by the instruction input, the identification display means displays whether the front surface corresponding state or the back surface corresponding state is present.
Therefore, when the instruction is inputted so as to correspond to the part viewed from the surface, and the right stitch or cut on the figure is selected by the part specifying means, the parameter setting means views the sewing product from the surface. In this case, it is assumed that the stitch or cut on the right side is selected, and setting input such as a setting value of a sewing parameter by the parameter input means for the stitch or cut is accepted.
In addition, when an instruction is input so as to correspond to the part viewed from the back side, and the right stitch or cut on the figure is selected by the part designating unit, the parameter setting unit views the sewing product from the front. In this case, it is assumed that the stitch or cut on the left side is selected, and setting input such as a setting value of a sewing parameter by the parameter input unit is accepted for the stitch or cut.
Also, the setting of these sewing parameters is reflected in the formation control of the stitches or cuts.
Thus, even if the operator confirms the sewing product from either the front surface or the back surface, the operator can input the sewing parameter of the same set portion as the confirmed surface to the sewing parameter setting means, and the sewing product can be input to any surface. Even if confirmed from the above, it is possible to set parameters of each part without error.

Further, in the first aspect of the present invention, the parameter setting means inverts the graphic of each opposing seam or each opposing cut displayed on the display unit across the straight line corresponding to the inversion of the corresponding part by the corresponding part switching means. To display. That is, the state viewed from the front surface is displayed in the front surface corresponding state, and the state viewed from the back surface is displayed in the back surface corresponding state, so that the state is different between the front surface view and the back surface view (each facing seam or each facing seam When the cut line is asymmetrical), it is easy to visually display whether the sewing parameter setting means corresponds to the part viewed from the front or the part viewed from the back. In addition, it is possible to further suppress erroneous input even if the sewing product is confirmed on the front surface or on the back surface.

Then, according to the sewing parameter input processing program 62a, the CPU 61 controls the liquid crystal display panel 93 to display the background image of the sewing parameter input screen G2 based on the background image data D1, and superimposes the graphic image data on the background image. Various operation buttons B1 to B5 based on the button icon data D4 are displayed in the arrangement defined in the button table D5 (or D6) in the front view form (or back view form) while displaying the image display area A2 based on D2 (or D3). To display. When an operation input to the display switching button B5 is detected, an image display area A2 based on the graphic image data D3 (or D2) is displayed on the background image, and a back view (or front view) button is displayed. Various operation buttons B1 to B5 are displayed based on the button icon data D4 in an arrangement determined in the table D6 (or D5).

Here, the button table D5 in the front view display state (FIG. 6A) and the button table D6 in the back view display state (FIG. 6B) will be described with reference to FIG. In addition, description of the setting matter about button B5-B7 is abbreviate | omitted in each button table D5, D6 in FIG.
The operation buttons B1 and B3 are buttons respectively arranged on the upper right and lower right of the image display area A2 in the sewing parameter input screen G2, and the operation buttons B2 and B4 are displayed on the sewing parameter input screen G2, respectively. These buttons are arranged at the upper left and lower left of the area A2, and each of the buttons B1 to B4 is composed of a + one setting button that increases and decreases the set value. In the button table D5 in the front-view display state, the operation buttons B1 to B4 are arranged on the screen (indicated by coordinates Xn and Yn, where n = 1 to 4), and the operation buttons B1 to B4 are located at the left or right corner. Function assignments indicating which sewing parameter set values for the breaks VFR and VFL are input are recorded. Here, for the operation buttons B1 and B3 arranged close to the corner cut (set part) arranged on the right side of the straight cut in the graphic displayed in the image display area A2, the sewing knife corner right width setting is started. And the setting value input of the right corner knife operation position setting at the start of sewing is assigned, and the operation buttons B2 and B4 arranged close to the corner cut (set part) arranged on the left side of the straight cut are respectively left at the corner knife left at the sewing start. Set value input for width setting and left corner knife operation position setting at the start of sewing is assigned.
In the button table D6 in the rear view display state, the arrangement of the operation buttons B1 to B4 and the function assignment are recorded as in D5. Here, for the operation buttons B1 and B3 arranged close to the corner cut (set portion) arranged on the right side of the straight line cut in the graphic displayed in the image display area A2, the corner knife left width setting at the sewing start is set. And the setting value input for the left corner knife operation position setting at the start of sewing is assigned, and for the operation buttons B2 and B4 arranged close to the corner cut (set part) arranged on the left side of the straight cut, the corner knife right at the sewing start Set value input for width setting and right corner knife operation position setting at the start of sewing is assigned.
Then, when the CPU 61 detects an operation input to the switching button B5 by the sewing parameter input processing program 62a, the button table D5, D6 is selected when the button is input in accordance with the switching of the display state between the front view and the back view. Switch the setting of whether to refer. Accordingly, the button table D5 is set to be referred to when switched to the front view display state, and the button table D6 is set to be referred to when switched to the back view display state.
Thereby, the CPU 61 recognizes the left and right corner cuts, which are the respective set parts displayed on the figure, as the corner cuts when the sewing products M and T are viewed from the surface (display) by the instruction input from the switching button B5. The left and right corner cuts are regarded as the left and right corner cuts VFL and VFR when the sewing product is viewed from the front surface, and whether the corner cuts are viewed from the back side (states on the left and right on the display). It functions as a corresponding part switching means for switching between the left and right corner cuts VFR and VFL when the workpiece is viewed from the back side.
Further, as described above, the switching button B5 is a state in which the left and right corner breaks displayed on the figure in the process as the corresponding part switching means are recognized as the corner breaks seen from the surface of the sewing product (surface view display state). In the case of the button icon, the direction of the line of sight is shown on the button icon, and the left and right corner cuts displayed on the figure in the processing as the corresponding part switching means are recognized as the corner cuts seen from the back side of the sewing product (back view display state) At this time, the direction of the line of sight is shown on the button icon, so that it functions as an identification display means for displaying the state corresponding to either the front surface or the back surface in a distinguishable manner.

  Further, when the CPU 61 detects an operation input to the surface of the display input unit 91 by the touch panel 94, the CPU 61 obtains the detection position and identifies whether the current display is the front view form or the back view form, and according to the identification. With reference to the button table D5 or D6, it is determined whether the detection position matches the arrangement of any of the operation buttons B1 to B5. If they match, the operation buttons B1 to B5 are assigned and the process proceeds.

  As described above, by executing the sewing parameter input processing program 62a, the CPU 61 changes the display form of the graphic in the image display area A2 in accordance with the execution of the processing as the corresponding part switching means by the instruction input by the switching button B5. Control is performed to switch between the viewing mode and the backside viewing mode (reversing and displaying each corner cut between straight cuts).

FIG. 8 is a flowchart showing the flow of input processing based on the sewing parameter input processing program 62a. Thus, the process will be described in detail.
First, when the sewing parameter input processing program 62a is executed, a sewing parameter input screen (here, the above-described sewing parameter input screen G2) is displayed (step S1). In the initial display, either the front view form or the back view form is displayed according to a predetermined default setting. Here, a description will be given assuming that the default is a setting for displaying the surface view form.

Next, it is determined whether or not an input operation is performed on the sewing parameter input screen G2 using the touch panel 94 (step S2). If there is no input operation, the determination is repeated.
Further, when there is an input operation, it is determined whether or not the display of the current sewing parameter input screen G2 is in the front view form (step S3), and in the case of the front view form, the button table D5 of the front view form is read out. Perform (step S4). If the current display is not in the front view mode, the button table D6 in the back view mode is read (step S5).
Then, it is determined whether or not the input operation position detected by the touch panel 94 in step S2 corresponds to the position of the operation buttons B1 to B4 (step S6), and if so, the current sewing parameter screen G2 is displayed. The set numerical values of the setting items corresponding to the operation buttons B1 to B4 determined with reference to the corresponding button table (D5 or D6) are increased or decreased and stored in the RAM 63 (step S7), and the process returns to step S2.

  If the input operation position does not correspond to any of the operation buttons B1 to B4, it is determined whether or not the input operation position detected by the touch panel 94 in step S2 corresponds to the position of the switching button B5 ( Step S8) If applicable, display switching of the sewing parameter input screen G2 is executed. That is, when the display of the current sewing parameter input screen G2 is the front view form of FIG. 6A, the display is switched to the back view form of FIG. 6B, and the display of the current sewing parameter input screen G2 is FIG. In the case of the rear view form of B), the front view form of FIG. 6A is switched (step S9). Then, the process returns to step S1.

If the input operation position does not correspond to the position of the switching button B5, it is determined whether or not the input operation position detected by the touch panel 94 in step S2 corresponds to the position of the confirmation button B6 (see FIG. 6) ( In step S10), if applicable, if the set numerical value has been changed in step S7, the numerical value is determined and stored in the EEPROM 64 (step S11). Then, the sewing parameter input screen G2 is closed and the process is terminated (step S13).
If the input operation position does not correspond to the position of the confirm button B6, it is determined whether or not the input operation position detected by the touch panel 94 in step S2 corresponds to the position of the cancel button B7 (see FIG. 6) ( If the cancel button B7 does not coincide with the cancel button B7), the process returns to step S2 assuming that the button is in contact with an area where no button exists. If the input operation position corresponds to the position of the cancel button B7, the sewing parameter input screen G2 is closed and the process is terminated (step S13). At this time, if the set numerical value has been changed in step S7 The number is discarded.

(Effect of embodiment)
As described above, the display input unit 91 of the edge stitch sewing machine 10 displays the graphic in the image display area A2 by switching between the front view mode and the back view mode on the sewing parameter input screen G2 under the control of the operation control unit 60. In the display of the surface view form, visual display is performed so that the correspondence between each cut of the figure displayed on the surface view and the operation buttons B1 to B4 corresponding to the cuts can be identified. . When displaying the rear view, visual display is performed so that the correspondence between the cuts of the graphic displayed in the back view and the operation buttons B1 to B4 corresponding to the cuts can be identified. At the same time, the operator switches the button tables D5 and D6 indicating the correspondence between the operation buttons B1 to B4 and the set parts in the figure, so that the operator can confirm the sewing product from either the front surface or the back surface. However, the switching button B5 causes the same graphic as the confirmed surface to be displayed and allows the operation control means 60 to input a button with a button arrangement corresponding to the front view or a button arrangement corresponding to the rear view. Even if either the front surface or the back surface is displayed, a display is provided so that the correspondence between the setting parts of the graphic seen from each surface and the operation buttons B1 to B4 as the setting input means can be visually identified. Therefore, it is possible to perform the setting of the sewing parameters for each cut without mistakes, regardless of which surface the sewing product is confirmed from.
In addition, since the touch panel 94 is adopted as the display input means 91, the position of the operation buttons B1 to B4 can be easily switched to follow the switching between the front view form and the back view form, and each figure is always cut. And the operation buttons B1 to B4 can be visually distinguished from each other, and it is possible to further prevent erroneous input when switching between the front and back sides.
In addition, the icon display of the switching button B5 indicates that the operation control means 60 can currently identify the front view corresponding state or the back view compatible state, and the front view compatible state and the back surface. In each of the visual correspondence states, a corner break in front view or back view is shown in the display image area A2, so that it is possible to further suppress erroneous input when switching between the front and back sides.

(Other)
As in the above embodiment, the sewing parameter input device for the sewing machine is not limited to being installed as a part of the sewing machine, and may be a device independent from the sewing machine that performs only the sewing parameter setting input. good.
Further, the sewing parameter input device of the present invention is not limited to the one for inputting the sewing parameters of the edge stitch sewing machine, but the stitch portions parallel to both sides of the cut parallel to the cloth feed direction to be the button hole. Various types of sewing machines that require setting of sewing parameters relating to the disposition of cuts in advance, such as a perforated-hole sewing machine in which a thread is formed, may be used.
Each sewing parameter is input with an actual numerical value or is not limited to this, and a correction ratio (%) with respect to the current set value may be input.
In addition, in the case of a seam with a symmetrical shape such as a seam of an eyelet perforated sewing machine, display switching is not performed, but only button input in the front view compatible state and button input in the back view compatible state is performed. Anyway.
In addition, as an example of switching between the corresponding state state in the front view and the corresponding state state in the rear view, only a part of the sewing parameter input screens illustrated in FIGS. 3 and 4 is illustrated. However, the corresponding state in the front view and the corresponding state in the back view may be switched when other remaining sewing parameters are input.

Further, in the above-described bead-sewn sewing machine 10, the switch button B5 for performing display and corresponding switching is disposed in the sewing parameter input screen G2 for inputting the setting of the sewing parameters. However, the present invention is not limited to such an example. A switching setting screen G3 (see FIG. 9) for preparing a display that can be displayed by a button input operation and a corresponding switching setting from an upper screen (for example, a sewing parameter input screen G1) is prepared, and a switching button B8 (so-called “so-called”) is displayed on the screen G3. A memory switch) may be provided so that direct display and correspondence switching cannot be performed on the input screen G2 for setting the sewing parameters. Accordingly, it is possible to prevent erroneous input of sewing parameters caused by inadvertent touching or the like on the switching button B5 when the sewing parameter input screen G2 is displayed, thereby causing an unexpected display and corresponding switching.
In this case, the switching button B5 is not displayed on the sewing parameter input screen G2, but is currently displayed as shown in the sewing parameter input screen G2 ′ in FIGS. 10A and 10B, for example. Display H1 and H2 (for example, the same display as that applied to the switching button B5) may be provided on the screen indicating whether the screen is in the front view form and the front view correspondence state or the back view form and the back view correspondence state. .

Moreover, in the said embodiment, although the touch panel 94 is employ | adopted for the display input means 91, it is not restricted to this. For example, like the display input unit 91A (sewing parameter input device) shown in FIG. 11, a liquid crystal display panel 93A (display unit) of a graphic showing a cut or a stitch applied to the sewing object is arranged at the center, May be provided with operation buttons BA1 and BA2 for performing a normal pressing operation. In this case, even if the display is switched, the arrangement of the operation buttons cannot be freely changed as in the touch panel, but each part of the figure and the operation button BA1 are displayed on the liquid crystal display panel 93A (arrows in the figure). , BA2 may be clarified before and after display switching.
In this example, the front end of the seam is set using the operation button BA1 and the rear end is set using the operation button BA2. In the rear view, the front end of the seam is set using the operation button BA2. The end setting is changed so as to be performed by the operation button BA1, but it is desirable to prepare such a change of the setting in advance as a button table.

In the example of FIGS. 6 and 7, since the setting input is performed simultaneously with the setting input by performing an operation input on any of the operation buttons B1 to B4, each operation button B1 to B4 is designated by the site designation. Although the functions of the means and the parameter input means are performed at the same time, these functions may be input by different methods.
For example, as shown in FIG. 12, a set part currently selected around a figure (a front view and a back view may be switched by a liquid crystal panel or the like, or a fixed image printed on a plane may be used). The display lamps L1 to L4 are displayed, a selection button BB1 for selecting a set part to which a current sewing parameter is to be input, a sewing parameter set value increase / decrease button BB2 for the selected setting part, and a figure selection An operation panel provided with display lamps L5 and L6 indicating whether the set portion corresponding to front view or back view and a switching button BB3 for switching between the front view correspondence state and the back view correspondence state May be used. In this case, the selection button BB1 functions as a part designating unit for designating which set part the sewing parameter is set, and the increase / decrease button BB2 functions as a parameter input unit for inputting a sewing parameter corresponding to the set part. Thus, the switching button BB3 functions as a means for instructing input of switching in the inversion control as the corresponding part switching means, and the display lamps L5 and L6 function as the identification display means.

The sewing parameters are not limited to those shown in FIGS. 3 and 4. For example, the tension of the sewing thread can be controlled by a solenoid or a motor, and each set position (for example, each of a pair of straight stitches) is individually controlled. In a sewing machine that performs thread tension setting, the thread tension setting may be included as a sewing parameter.
Also in this case, as shown in FIG. 13, two straight stitches displayed as graphics in the display image area AC1 of the operation panel 91 and each of the operation buttons BC1 and BC2 for inputting the sewing parameters are displayed on the display input means. 91, a switching button BC3 may be provided to select whether the correspondence between the displayed setting parts and the operation buttons BC1 and BC2 corresponds to front view or back view. . Display switching may also be performed.
