Description

  The present invention relates to a buttoning data creation device and a buttoning data creation method for creating data for buttoning on a sewing machine, and more particularly to creating movement amount data that defines needle entry point data for buttoning. The present invention relates to a technique for improving the data structure of the movement amount data of the data, and enabling the data expansion / contraction according to the change of the button hole interval and the data expansion / contraction according to the change of the button hole size independently.

  Conventionally, when a button is attached to a fabric, a tack-stitch sewing machine has been used. The barbed sewing machine includes a button holding presser arm that holds a button, and a feed base and a feed plate that hold a cloth. The barbed sewing machine performs buttoning on the cloth by independently moving the button holding presser arm, the feed base and the feed plate in the X and Y directions based on the needle entry point data. Buttons vary widely in button size, button hole spacing, button hole size, and the number of button holes for each button.

  Conventional needle drop data with buttons is similar to sewing data for sewing a general pattern. As shown in FIG. 19, the needle drop point data includes initial movement data from the coordinate origin to the needle drop point S1 of the first needle, and needle drop points Si (i = 2, 3,...) After the first needle. And a plurality of needle entry point data representing the amount of movement for moving the fabric in the X and Y directions. In the needle point data, multiple needle points and the needle drop order are determined, but the relationship between the needle point and the button hole is determined based on the mechanical coordinate origin setting position. In order to match this button, the size was adjusted by enlarging / reducing the entire buttoned sewing pattern.

  Conventionally, when creating needle drop point data used for button attachment, an operator switches the screen of a personal computer to a CAD screen. Next, the operator associates the unit length on the screen of the personal computer with the actual length, and then inputs a plurality of needle drop points on the screen in the sewing order. Thereafter, when the operator instructs the creation of needle drop point data, the buttoning data creation device creates the needle drop point data in association with the coordinate data of the plurality of needle drop points and the needle drop order.

  In the sewing data size changing method described in Patent Document 1, when the X and Y movement amount data (needle entry point data) is enlarged or reduced, the X and Y movement amounts are only obtained when the movement distance for feeding the cloth is a predetermined value or more. It was configured to scale the data. In the sewing data size changing method described in Patent Document 1, X and Y movement amount data in which the movement distance is less than a predetermined value, such as back stitching, is not scaled. The automatic sewing machine sewing data creation apparatus described in Patent Document 2 employs a technique for preventing the creation of sewing data in which the interval between the needle drop points is equal to or greater than a predetermined value.

Japanese Patent Laid-Open No. 10-137466 JP-A-7-300764

  Conventionally, it has been necessary to prepare needle drop point data used for button attachment every time the button size changes. In that case, in many cases, the change in the button size is dealt with by enlarging or reducing previously generated needle entry point data in accordance with the enlargement or reduction of the button hole interval. However, when the needle drop point data is enlarged or reduced, the interval between the plurality of needle drop points in the button hole is also enlarged or reduced. As a result, there is a problem that proper sewing becomes difficult if the interval between the needle drop points is too small. There was a problem that the quality of the sewing product at the last two or three stitches was deteriorated. When the interval between the needle drop points becomes too large, there is a problem that some needle drop points protrude from the button holes.

  When creating needle entry point data, the operator enlarges or reduces the needle entry point data on the display screen, and then checks whether each needle entry point is appropriate for the buttonhole. However, the needle point data was appropriately corrected. Therefore, the operator has required a great deal of effort to create needle point data with buttons. The button-attached sewing machine control apparatus needs to store needle drop point data for a wide variety of buttons, so that the required memory capacity is large and management of the needle drop point data is troublesome.

  The object of the present invention is to make it easy to deal with a wide variety of buttons, so that the needle drop point data for button-attached sewing is the amount of movement data between holes indicating the button hole interval, and the movement in the hole with the reference point in the button hole as the origin. It is to provide a buttoning data creation device and a buttoning data creation method configured with quantity data.

Based on the reference position of each button hole set by the setting means, the movement between the button holes from each button hole to the next button hole based on the reference position of each button hole set by the setting means A movement amount calculation means between holes for calculating an amount as a movement amount between button holes, and a plurality of movement amounts in the hole calculated by the movement amount calculation means in the hole, It is characterized by comprising a plurality of movement amounts between button holes calculated by the movement amount calculation means between holes.

  The input means inputs position information of a plurality of needle entry points in the order of needle entry. The setting means sets a reference position of each button hole for a plurality of button holes included in the button. The calculation means determines the button hole to which each needle drop point belongs based on the position information of the needle drop point and the reference position of each button hole. The in-hole movement amount calculating means includes a button to which the needle drop point belongs for each needle drop point in the needle drop order based on the reference position of the button hole to which each needle drop point belongs and the position information of each needle drop point. The amount of movement from the reference position of the hole is calculated as the amount of movement in the hole. The movement amount calculation means between the holes calculates the movement amount between the button holes from each button hole to the next button hole as the movement amount between the button holes in the needle drop order based on the reference position of each button hole. The data defining the needle drop point is composed of the plurality of movement amounts in the hole and the plurality of movement amounts between the button holes, and button drop needle point data is created from these movement amount data.

  According to a second aspect of the present invention, there is provided the button attachment data creating device according to the first aspect, wherein the center position of the button is a coordinate origin, and the first needle drop out of the button holes to which the needle drop points calculated by the calculation means belong. Further, the present invention is characterized by further comprising first needle hole movement amount calculation means for calculating the movement amount between button holes for the first needle based on the reference position of the button hole to which the point belongs and the coordinate origin.

  According to a fourth aspect of the present invention, there is provided the buttoning data creation device according to the first or second aspect, wherein the storage unit stores template data of a template in which the coordinate origin and the reference position of each button hole are associated with each other. It further comprises display means capable of displaying a needle drop point and the template stored in the storage means, and an instruction means for instructing the plurality of needle drop points and the template so that the position of the needle drop point and the template can be adjusted. .

  The buttoning data creation method according to claim 5 is a buttoning method for creating movement amount data for defining needle drop point data for performing buttoning by moving and driving a movable holding member capable of holding a button and a cloth by a buttoning machine. In the data creation method, a first step of inputting position information of a plurality of needle drop points in the needle drop order, a second step of setting a reference position of each button hole for the plurality of button holes of the button, and the first A third step of determining a button hole to which each needle drop point belongs based on the position information of the needle drop point input in one step and the reference position of each button hole set in the second step; Based on the reference position of the button hole to which each needle drop point determined in the process belongs and the position information of each needle drop point, the reference position of the button hole to which the needle drop point belongs for each needle drop point in the order of needle drop Or The fourth step of calculating the amount of movement as the amount of movement in the hole, and between the button holes from each button hole to the next button hole in the needle drop order based on the reference position of each button hole set in the second step And a fifth step of calculating the amount of movement as the amount of movement between the button holes.

Data that defines needle point data for buttons can be created easily and efficiently.

  By appropriately setting the second magnification described above, it is possible to reliably prevent the interval between the plurality of needle drop points in the button hole from becoming too small or too large. Can be secured. For standard-sized buttons, if you create data that defines multiple needle drop points based on the movement amounts in the holes and movement amounts between the button holes, it is suitable for various buttons with different sizes. Since it is possible to easily create data that defines the needle entry point, it is not necessary to store a large number of needle entry point data for various buttons.

  According to the invention of claim 2, the center position of the button is a coordinate origin, and the button hole to which the first needle drop point belongs among the button holes to which each needle drop point calculated by the calculation means belongs, Further, since the first needle hole movement amount calculating means for calculating the movement amount between the button holes for the first needle based on the coordinate origin is further provided, the first needle can be changed according to the change of the button size. The movement amount between the button holes for the first needle can be enlarged and reduced together with the movement amounts between the button holes other than the movement amount between the button holes for the needle. The calculation process for creating the movement amount data between the button holes from the coordinate origin to the needle drop point for the first needle is simplified.

  According to the invention of claim 3, since the reference position of the button hole is the center position of each button hole, each needle drop point protrudes from the button hole using the data of the movement amount of the plurality of needle drop points in the hole. The arithmetic processing for checking whether or not is simplified.

In such a state, the relative position can be adjusted by the instruction means.

  According to the invention of claim 5, the same effect as that of claim 1 can be obtained.

  Hereinafter, the best mode for carrying out the present invention will be described based on examples.

  This buttoning data creation device is a device for creating movement amount data that defines needle drop point data for buttoning by moving and driving a movable holding member capable of holding a button and a cloth by a buttoning sewing machine. In the following embodiments, the “button hole” refers to a hole that is dropped on a needle when the button is formed on the button.

  The buttoned data creation apparatus 1 is composed of the personal computer 1 shown in FIGS. The personal computer 1 includes a CPU 6, a ROM 7, a RAM 8, a hard disk controller 10, a hard disk 11, a memory card interface 12, an input / output interface 9, a keyboard 3 connected to the computer main body 2, and a computer main body 2. And a mouse 5 connected to the computer main body 2. The computer main body 2 can read and write the memory card 13 as an external storage medium via the memory card interface 12 connected to the input / output interface 9. The hard disk 11 stores in advance a control program for buttoned data creation control shown in the flowcharts of FIGS. 6, 11, and 12.

  Next, the buttoning data creation control and the creation method will be described based on a flowchart. In the flowchart, symbol Si (i = 1, 2,...) Indicates each step. As shown in FIG. 6, when this control is started, initial settings such as starting predetermined CAD software are first executed (S1), and then the screen 4a of the display 4 is switched to the CAD screen, and then the screen 4a is displayed. A plurality of needle drop points S1 to S7 (see FIG. 3) for unit length setting processing and button attachment for associating the unit length with the actual length are input on the screen 4a in the needle drop order, and the needle drop points S1 to S7. Is stored in the work memory of the RAM 8 (S2). The unit length setting process is a process of setting one grid (a grid) corresponding to one scale on the screen 4a to, for example, 1.0 mm.

  For example, as shown in FIG. 3, when inputting a plurality of needle drop points S1 to S7 on the screen 4a in the order of needle drop, the mouse 5 is instructed by a pointer (not shown) on the screen 4a. By inputting the execution command, the coordinate origin G and the needle drop points S1 to S7 are input. As a result, the XY coordinate values, needle drop orders, and button-attached sewing patterns of the plurality of needle drop points S1 to S7 are determined. When the needle drop points S1 to S7 are input in this way, a number indicating the needle drop order is also displayed. When inputting the needle drop points S1 to S7, the needle drop points S1, S2, S4 and S3, S5, S6, S7 are set in a grid (a grid) smaller than the button hole. The needle drop points S1 to S7 thus set and the XY coordinate values based on the coordinate origin G are as shown in FIG.

  Next, as shown in FIG. 5, the buttonhole template T is input and set in S3, and the buttonhole template T is displayed on the screen 4a of the display 4. The button hole template T has a coordinate origin G in the XY coordinate system (the coordinate origin G is set at the center of the button), button holes H1 and H2, and centers C1 and C2 of the button holes H1 and H2 (this is the button hole). Reference point = button hole coordinate origin). The button hole template T includes button hole size, button hole number, button hole dimension information, and coordinate origin G information input and set from the keyboard 3. However, the button hole template T may be selected and set from a plurality of types of button hole templates that are input and set in advance.

  Next, in S4, a template wrap process is performed in which the buttonhole template T is moved and wrapped at a plurality of needle drop points S1 to S7. The operator wraps the button hole template T at a plurality of needle drop points S1 to S7, thereby setting the positions of the centers C1 and C2 of the button holes H1 and H2, and setting a button-attached sewing pattern.

  As shown in FIG. 5, the template wrap process is performed by inputting a command to move the origin G on the template T to the origin G on the buttoned sewing pattern side after pointing the buttonhole template T with the pointer on the screen. Execute. The pointer and mouse 5 on the screen correspond to “instruction means” for instructing the plurality of needle drop points S1 to S7 and the template T to be position-adjustable. However, the order may be reversed, and the buttonhole template 30 may first be input and set and displayed, and then a plurality of needle drop points 1 to 7 and the coordinate origin G may be input and set.

  Next, in S5, the position information of the coordinate origin G, the position information of the reference positions of the plurality of button holes H1 and H2, and the position information of the plurality of needle drop points S1 to S7 input and set as described above are used. Based on this, the button-attached movement amount data creation process is executed.

  Here, information related to the button-attached movement amount data creation processing is shown in FIGS. 8 to 10 and FIGS. 13 to 18. FIG. 8 shows the button hole number, the symbol of the button hole center, and the XY coordinates of the button hole center when there are two button holes. FIG. 9 is a view corresponding to FIG. 8 when there are three button holes. FIG. 10 is a view corresponding to FIG. 8 when there are four button holes.

FIG. 13 shows the coordinate origin G, the plurality of needle drop points S1 to S7, the button holes H1 and H2 and their centers C1 and C2, and the button sewing, which are input and set in S1 to S4 in FIG. An example of a screen display such as a pattern is shown. FIG. 15 is a view corresponding to FIG. 13 when there are three button holes. FIG. 17 is a view corresponding to FIG. 13 when there are four button holes.
FIG. 14 shows a table of movement amount data defining the needle drop point data obtained by the button attachment movement amount data creation processing shown in the flowcharts of FIGS. 11 and 12 based on the various information described above.

  The “main movement amount” of the data rank 0 is the X-direction movement amount and the Y-direction movement amount from the coordinate origin G to the reference point C1 (= button hole center) of the button hole H1 including the needle drop point S1 (this is the “first movement amount”). Corresponding to “the movement amount between button holes for one needle”). In this example, since the distance between the button holes is 5 mm and the coordinate origin G is the center of the two button holes, the numerical value is (−2.5, 0). The “main movement amount” of the data rank 1 is the X-direction movement amount and the Y-direction movement amount (from the reference point C1 of the button hole H1 including the needle drop point S1 to the reference point C1 of the button hole H1 including the needle drop point S2 ( This corresponds to “the amount of movement between button holes”). Since the needle drop point S1 and the needle drop point S2 are created in the same button hole, the numerical value is (0, 0). The same applies to the “main movement amount” after the data ranking 2.

  The “correction movement amount” of the data rank 0 indicates the x-direction movement amount and the y-direction movement amount in the xy coordinate system from the reference point C1 of the button hole H1 including the needle drop point S1 to the needle drop point S1. The “correction movement amount” in the data rank 1 indicates the x-direction movement amount and the y-direction movement amount from the reference point C1 of the button hole H1 including the needle drop point S2 to the needle drop point S2. The “correction movement amount” after the data rank 2 is the same as described above. The “correction movement amount” described above corresponds to the “in-hole movement amount”. FIG. 16 is a view corresponding to FIG. 14 when there are three button holes. FIG. 18 is a view corresponding to FIG. 14 when there are four button holes.

  Next, the buttoning movement amount data creation processing will be described with reference to the flowcharts of FIGS. After the start of this process, first, the data rank counter Dn is set to “0” in S10. Next, in S11, the needle entry point number Sn is set to "1". Next, in S 12, the button hole closest to the needle drop point Sn (= S 1) is searched, the button hole reference position (XB, YB) is calculated, and stored in the work memory of the RAM 8.

  Based on the flowchart of FIG. 12, the button hole search process in S12 will be described. After the start of this process, the number of button holes is first set in the counter H in S30. Next, in S31, the loop counter N is set to “0”. Next, in S32, it is determined whether or not N = H. If the determination is No, the loop counter N is incremented by “1” in S33.

  Next, in S34, the distance between the needle drop point Sn and the reference position C (N) of the button hole H (N) is calculated. In the next S35, it is determined whether N = 1. If the determination is Yes, the calculated distance is stored in the work memory of the RAM 8 (S36). Next, the counter M is set to “N” in S37, and then the process returns to S32 to repeat S32 and subsequent steps. If the determination in S35 is No, it is determined whether or not the distance calculated in S34 in S38 is shorter than the distance stored in the RAM 8. If the determination is No, the process returns to S32.

  However, if the determination in S38 is Yes, the current distance is overwritten on the distance stored in the RAM 8 (S39). Next, in S40, the counter M is set to N, and the process proceeds to S32. When the determination in S32 is Yes, the above-described distance calculation is executed for all button holes, and the button hole closest to the needle entry point Sn is detected. Therefore, in S41, the coordinates (X (C (M), Y (C (M))) of the reference position C (M) of the button hole H (M) are rewritten and stored in the work memory of the RAM 8. Then, the process proceeds to S13 in FIG.

  Next, in S13 of FIG. 11, since (XB, YB) is a value for the needle drop point S1, (XB, YB) is set to (XB (1), YB (1)). Next, in S14, the movement amount in the X direction and the movement amount in the Y direction from the origin G to the reference position (XB (1), YB (1)) of the button hole closest to the needle drop point S1 is calculated, and the data ranking is calculated. It is stored in the work memory table of the RAM 8 as “main movement amount” of 0. Next, in S15, the X-direction movement amount and the Y-direction movement amount from (XB (1), YB (1)) to the needle entry point S1 (X (S1), Y (S1)) are calculated, and the data rank 0 Is stored in the work memory table of the RAM 8.

  Next, in S16, the data rank counter Dn is incremented by “1”, and the needle entry point number Sn is incremented by “1”. Next, in S17, it is determined whether or not there is no data of the needle entry point Sn. If the determination is No, the process proceeds to S18. In S18, as in S12 (flowchart in FIG. 12), the button hole closest to the needle drop point Sn is searched, and the button hole reference position (XB, YB) is calculated.

  Next, in S19, since (XB, YB) is a value with respect to the needle drop point Sn, the coordinates of (XB, YB) to the reference point (XB (Sn), YB (Sn)) of the button hole including the needle drop point Sn. Set the value. Next, in S20, the button hole reference point (XB (Sn-1)) including the needle drop point Sn from the button hole reference point (XB (Sn-1), YB (Sn-1)) including the needle drop point Sn-1. ), YB (Sn)) and the movement amount in the X direction and the movement amount in the Y direction are calculated and stored in the work memory table of the RAM 8 as the “main movement amount” of the data rank Dn.

  Next, in S21, the movement amount in the X direction from the reference point (XB (Sn), YB (Sn)) of the button hole including the needle drop point Sn to the needle drop point Sn (X (Sn), Y (Sn)) and The movement amount in the Y direction is calculated and stored in the work memory table of the RAM 8 as the “correction movement amount” of the data rank Dn. By calculating from “S21” to “S16” and repeating “S16” and subsequent steps to calculate the “main movement amount” and “correction movement amount” for all the needle entry points, the determination of S17 becomes “Yes”, and this button is attached. The data creation process ends.

  The operation and effect of the button creation data creation apparatus and the creation method described above will be described. Since the movement amount data defining a plurality of needle drop points is composed of a plurality of corrected movement amounts (in-hole movement amounts) and a plurality of main movement amounts (movement amounts between button holes) obtained as described above, the button size is configured. When the button hole interval is enlarged or reduced in accordance with the change of the first and second magnifications, the first magnification for enlarging / reducing the plurality of main movement amounts and the magnification for enlarging / reducing the plurality of correction movement amounts are enlarged / reduced at different second magnifications. Therefore, it is possible to easily and efficiently create movement amount data that defines needle point data for buttons of different sizes.

  By appropriately setting the second magnification, it is possible to reliably prevent the interval between the plurality of needle drop points in the button hole from becoming too small or too large, and to ensure the quality of the sewing product with buttons. . For standard-sized buttons, if you create movement amount data that defines multiple needle drop points using the multiple correction movement amounts and multiple main movement amounts described above, it is suitable for various buttons of different sizes. It is possible to easily create movement amount data that defines the needle entry point, and it is possible to easily create multiple needle entry point data for attaching buttons from the movement amount data. There is no need to store a large number of needle entry point data.

  Based on the reference position of the button hole to which the first needle drop point belongs among the button holes to which each needle drop point belongs and the coordinate origin, the center position of the button is the main point for the first needle. In order to calculate the movement amount (movement amount between the button holes), the main movement amount for the first needle as well as the plurality of main movement amounts other than the main movement amount for the first needle according to the change of the button size. Can be scaled. The arithmetic processing for creating the main movement amount data from the coordinate origin to the needle drop point for the first needle is simplified.

  Since the reference position of the button hole is the center position of each button hole, a calculation is performed to check whether or not each needle drop point protrudes from the button hole by using the correction movement amount data of a plurality of needle drop points. The calculation process is simplified.

  Template data of a template T that associates the coordinate origin with the reference position of each buttonhole is stored, and a plurality of needle drop points and the stored template T are displayed on the display 4, By instructing the needle drop point and the template T with the pointer of the screen 4a and the mouse 5, the relative positions thereof can be adjusted.
