  An example of the sewing information will be described with reference to FIG. The sewing information includes a plurality of needle drop points according to a predetermined sewing order. The needle drop point is a planned position where the sewing needle 11 attached to the needle bar 9 is stuck in the cloth. The plurality of needle entry points include at least a first start point and a last end point in the sewing order. The editing device 8 can output sewing information to the sewing machine 1. In the sewing machine 1, the CPU 101 receives the sewing information output from the editing device 8. The CPU 101 reads the needle entry points of the received sewing information in the order from the start point to the end point, and drives the X-axis motor 124 and the Y-axis motor 125. The sewing machine 1 performs pattern sewing based on the sewing information.

  As shown in FIG. 4, the sewing information 30 includes eight needle drop points in the order of points P1 to P8. Point P1 is the starting point. Point P8 is the end point. The needle entry point is indicated by relative coordinates (X, Y) with respect to the origin. X shows the relative coordinate of the left-right direction. Y shows the relative coordinate of the front-back direction. In the present embodiment, the origin of the XY coordinate system is the start point (point P1). The sewing information 30 includes a plurality of fields for storing information associated with each needle drop point. The code column of the sewing information 30 stores a type of code set by the operator among a plurality of types of codes.

  An example of a plurality of types of codes will be described. The editing device 8 can set a plurality of types of codes in association with a predetermined needle drop point that is at least one of the plurality of needle drop points. For example, the editing device 8 can set one type of codes among a plurality of types of codes as two or more needle drop points (predetermined needle drop points). The editing device 8 can set two or more types of codes among a plurality of types of codes as the same needle drop point (predetermined needle drop point). The code includes information defining a sewing operation of the sewing machine 1 to a needle drop point whose sewing order is later than a predetermined needle drop point associated with the code. In the sewing machine 1, when the CPU 101 sews the predetermined needle drop point, the main motor 123, the solenoid 128, the presser motor 129, etc. are controlled according to the code associated with the predetermined needle drop point, and the sewing is performed more than the predetermined needle drop point. Sewing to the needle entry point after the order.

  The plurality of types of cords of the present embodiment include a sewing speed cord, a thread tension cord, and a presser foot cord. In the code column of the sewing information 30, “A” indicates a sewing speed code, “B” indicates a thread tension code, and “C” indicates a presser foot code. In the sewing information 30, the sewing speed code “A” is associated with the point P2. The sewing speed code “A” and the presser foot code “C” are associated with the point P6. The thread tension cord “B” does not correspond to any needle drop point.

  The sewing speed code will be described. The sewing speed code specifies the sewing speed. In the sewing machine 1, the CPU 101 changes the sewing speed (rotational speed of the output shaft of the main motor 123) after sewing to a predetermined needle drop point associated with the sewing speed code. The CPU 101 controls the main motor 123 to perform sewing at a sewing speed corresponding to the sewing speed code to a needle drop point whose sewing order is later than the needle drop point associated with the sewing speed code. For example, if the sewing speed at the time of sewing a needle drop point where the sewing direction changes abruptly, such as a turning angle, is too high, the point at which the sewing needle 11 actually pierces the cloth may deviate from the needle drop point. The operator sets a sewing speed code for decreasing the sewing speed in association with a needle drop point where the sewing direction or the like changes suddenly.

  The thread tension cord will be described. The thread tension cord defines the needle thread tension. The CPU 101 changes the needle thread tension after sewing to a predetermined needle drop point associated with the thread tension code. The CPU 101 controls the solenoid 128 to perform sewing to a needle drop point that is later in the sewing sequence than the needle drop point associated with the thread tension code with the upper thread tension according to the thread tension code. For example, if the sewing machine 1 is sewn with an inappropriate upper thread tension (thread tension), a stitch failure may occur. The operator associates and sets a thread tension code for adjusting the thread tension according to the thickness of the cloth to the needle drop point where the thickness of the cloth changes.

  The presser foot code will be described. The presser foot code defines the presser foot height. The CPU 101 changes the presser foot height after sewing to a predetermined needle drop point associated with the presser foot code. The CPU 101 controls the presser motor 129, and performs sewing to a needle drop point whose sewing order is later than the needle drop point associated with the presser foot code at a presser foot height corresponding to the presser foot code. For example, if the sewing machine 1 is sewn with an inappropriate presser foot height, the presser foot 13 may not be able to press the cloth properly. The operator sets the presser foot code that sets the presser foot height corresponding to the thickness of the cloth to the needle drop point where the thickness of the cloth changes.

  As shown in FIG. 4, the remarks column of the sewing information 30 stores values set by the operator according to each code. For example, the sewing speed code associated with the point P2 sets the sewing speed to 100 rpm. In this embodiment, the unit of rpm of the sewing speed indicates the rotational speed of the main motor 123 output shaft. The sewing speed code associated with the point P6 sets the sewing speed to 200 rpm. The presser foot code associated with the point P2 sets the presser foot height to 3 mm.

  When the sewing machine 1 performs pattern sewing based on the sewing information 30, zigzag stitches are formed on the cloth. The CPU 101 controls the main motor 123 to sew at a predetermined initial sewing speed from the point P1 (start point) to the point P2. The CPU 101 controls the main motor 123 according to the sewing speed code, and performs sewing from point P3 to point P6 at a sewing speed of 100 rpm. The CPU 101 controls the main motor 123 according to the sewing speed code, and performs sewing at a sewing speed of 200 rpm from the point P7 to the point P8 (end point). The CPU 101 controls the solenoid 128 to sew with the initial value upper thread tension from the point P1 (start point) to the point P8 (end point). The CPU 101 controls the presser motor 129 and sews from the point P1 (start point) to the point P2 with the initial presser foot height. The CPU 101 controls the presser motor 129 in accordance with the presser foot cord, and sews from the point P3 to the point P8 (end point) at a presser foot height of 3 mm.

  The main process will be described with reference to FIG. When the operator activates the editing apparatus 8, the CPU 81 executes main processing according to a program stored in the ROM 82. In the main process, the CPU 81 performs a process of editing sewing information, a process of outputting to the sewing machine 1 and the like. Hereinafter, an example in which the editing device 8 edits the sewing information 30 (see FIG. 4) will be described. The operator stores the sewing information 30 in the storage device 84 before editing the sewing information 30. The operator may create the sewing information 30 stored in the storage device 84 in advance by the editing device 8 or by another device. When the operator selects a later-described interlocking mode, the operator operates the power switch 127 to activate the sewing machine 1 in advance and holds the cloth with the holding body 60. The operator does not have to start the sewing machine 1 when selecting the non-interlocking mode described later.

  The CPU 81 displays the main screen 31 (see FIG. 6) on the display screen 86 (S1). As shown in FIG. 6, the main screen 31 includes a first area 32, a second area 33, and a third area 34. The first area 32 includes a needle drop point display area 32A and a sewing order display area 32B. The needle drop point display area 32A displays a plurality of needle drop points of the sewing information. The sewing order display area 32B indicates the total number of needle drop points in the denominator, and indicates the sewing order of the selected needle drop points in the numerator. The second area 33 displays buttons for inputting various instructions, and includes an instruction input field 33A, an interlocking mode selection field 33B, and a search code selection field 33C. The third area 34 displays information (coordinate information, code, etc.) associated with the needle entry point.

  As shown in FIG. 5, the CPU 81 determines whether there is a read instruction (S2). The operator presses a read instruction in the instruction input field 33A (see FIG. 6) on the operation panel 88 and selects sewing information to be edited from a plurality of pieces of sewing information stored in the storage device 84, whereby the read instruction is edited. 8 If there is no read instruction (S2: NO), the CPU 81 shifts the process to S5. For example, when the operator operates the operation panel 88 and selects the sewing information 30 to input a reading instruction to the editing device 8 (S2: YES), the CPU 81 stores the sewing information 30 according to the reading instruction in the storage device 84. (S3). The CPU 81 displays a plurality of needle drop points (points P1 to P8) of the sewing information 30 in the needle drop point display area 32A (see FIG. 6). The CPU 81 performs an editing process for editing the sewing information 30 (S4).

  The CPU 81 determines whether there is an output instruction (S5). The operator presses the output instruction in the instruction input field 33A on the operation panel 88 and selects the sewing information to be output from the plurality of sewing information stored in the storage device 84, thereby inputting the output instruction to the editing device 8. If there is no output instruction (S5: NO), the CPU 81 returns the process to S2. When there is an output instruction (S5: YES), the CPU 81 outputs the sewing information selected by the operator to the sewing machine 1 (S6). The CPU 81 returns the process to S2. In the sewing machine 1, the CPU 101 receives the sewing information output from the editing device 8. When the worker steps on the tread board 126, the CPU 101 starts pattern sewing based on the sewing information.

  The editing process will be described with reference to FIGS. In the editing process, the CPU 81 performs a process of specifying the needle entry point to be edited before editing the information associated with the needle entry point. When the CPU 81 reads the sewing information 30 from the storage device 84 (see S3, FIG. 5), the CPU 81 starts the editing process.

  As shown in FIG. 7, the CPU 81 performs an interlocking mode acquisition process (S11). The sewing system 10 has a non-linked mode and a plurality (two in this embodiment) of linked modes. The non-interlocking mode is a state of the sewing system 10 in which the editing device 8 that is editing the sewing information and the sewing machine 1 are not interlocked. The interlocking mode is a mode of the sewing system 10 in which the editing device 8 that is editing the sewing information and the sewing machine 1 are interlocked. The interlock mode includes a first interlock mode and a second interlock mode. In the first interlock mode, the editing device 8 outputs a first movement instruction described later to the sewing machine 1. In the second interlocking mode, the editing device 8 outputs a second movement instruction described later to the sewing machine 1.

  The operator presses one of the three modes displayed in the interlocking mode selection field 33B on the operation panel 88 and inputs a mode instruction to the editing device 8, thereby selecting one of the modes. The mode instruction includes a non-linked mode instruction, a first linked mode instruction, and a second linked mode instruction. The non-linked mode instruction, the first linked mode instruction, and the second linked mode instruction correspond to the non-linked mode, the first linked mode, and the second linked mode, respectively.

  In the interlock mode acquisition process, the CPU 81 acquires a mode instruction input by the operator (S11). When acquiring the first interlock mode instruction, the CPU 81 sets “1” in the interlock flag. When acquiring the second interlocking mode instruction, the CPU 81 sets “2” in the interlocking flag. When acquiring the non-linked mode instruction, the CPU 81 sets “0” in the linked flag. The interlock flag indicates whether the instruction acquired by the CPU 81 is the first interlock mode instruction, the second interlock mode instruction, or the non-interlock mode instruction, and is stored in the RAM 83.

  The CPU 81 performs cursor movement processing (S12). The operator selects any one from a plurality of needle drop points (points P1 to P8) in the sewing information 30. In this embodiment, the operator can select the needle entry point by operating the left key 89C or the right key 89D. By pressing the operation panel 88, the operator can select the needle drop point that is closest to the position pressed by the operator from the plurality of needle drop points displayed in the needle drop display area 32A.

  In the cursor movement process, the CPU 81 acquires the needle entry point selected by the operator. The CPU 81 moves and displays the cursor 35 to the acquired needle entry point among the plurality of needle entry points displayed in the needle entry point display area 32A. The cursor 35 displays the currently selected needle entry point as distinct from other needle entry points. The operator can grasp the currently selected needle entry point by confirming the needle entry point displayed by the cursor 35. The CPU 81 displays information (coordinate information, code, etc.) associated with the acquired needle entry point in the third area 34. When the sewing system 10 is in the interlock mode (that is, the interlock flag is “1” or “2”), the CPU 81 outputs an initial movement instruction for moving the sewing needle 11 and the cloth relative to each other to the sewing machine 1. The initial movement instruction includes coordinate information indicating the needle entry point selected by the operator. In the sewing machine 1, when the CPU 101 receives the initial movement instruction, the CPU 101 controls the X-axis motor 124 and the Y-axis motor 125, and holds the cloth 60 with respect to the sewing needle 11 to the position indicated by the needle drop point selected by the operator. Moving.

  The CPU 81 performs code type acquisition processing (S13). The operator depresses and selects a specific type of code on the operation panel 88 from a plurality of types of codes displayed in the search code selection field 33C. The specific type of code may be one type or two or more types. For example, when the operator wants to grasp a specific type of code associated with the needle entry point, he / she selects the type of code to be grasped. In the code type acquisition process, the CPU 81 acquires a specific type of code selected by the operator and stores it in the RAM 83.

  The CPU 81 performs a search start instruction acquisition process (S14). The operator operates the selection key 89 to input a search start instruction to the editing device 8. The search start instruction includes a first search start instruction for performing a forward search and a second search start instruction for performing a reverse search. In this embodiment, the operator can input a first search start instruction by long pressing the upper key 89A. In the forward direction search, the CPU 81 searches for a needle drop point associated with a specific type of code in accordance with the sewing order from the currently selected needle drop point. For example, when the operator searches from a needle point that is later in the sewing order than the currently selected needle point, the operator performs a forward direction search. The operator can input a second search start instruction by long pressing the down key 89B. In the reverse direction search, the CPU 81 searches for a needle drop point associated with a specific type of code in the reverse order to the sewing order from the currently selected needle drop point. For example, when the operator searches from a needle point that is before the needle point that is currently selected, the search is performed in the reverse direction.

  In the search start instruction acquisition process, the CPU 81 acquires a search start instruction input by the worker. When acquiring the first search start instruction, the CPU 81 sets “0” in the search flag. When acquiring the second search start instruction, the CPU 81 sets “1” in the search flag. The search flag indicates whether the instruction acquired by the CPU 81 is a first search start instruction or a second search start instruction, and is stored in the RAM 83.

  The CPU 81 determines whether or not there are a plurality of needle drop points in the sewing information 30 (S15). When the sewing information 30 does not have a plurality of needle drop points (S15: NO), the CPU 81 shifts the processing to S35. When there are a plurality of needle drop points in the sewing information 30 (S15: YES), the CPU 81 sets the point where the cursor 35 (see FIG. 6) is moved in S12 (that is, the currently selected needle drop point) as the target point ( S16). The target point is a needle entry point to be determined as to whether or not it is a needle entry point associated with a specific type of code in the later-described code confirmation process (S31).

  The CPU 81 refers to the search flag and determines whether or not the instruction acquired in S14 is a first search start instruction (S21). When the search flag is “0”, the CPU 81 determines that the acquired instruction is the first search start instruction (S21: YES). The CPU 81 determines whether or not the current target point is an end point (S22). If the current target point is not the end point (S22: NO), the CPU 81 sets the needle entry point that is one stitch after the needle entry point that is the current target point as the target point (S23). The CPU 81 moves the process to S31. When the current target point is the end point (S22: YES), the CPU 81 sets the start point as the target point (S24). When the CPU 81 performs the forward direction search from the needle entry point in the middle of the sewing order, it can search not only from the needle entry point to the end point in the middle but also from the start point to the needle entry point in the middle. The CPU 81 moves the process to S31.

  When the search flag is “1” in S21, the CPU 81 determines that the acquired instruction is a second search start instruction (S21: NO). The CPU 81 determines whether or not the current target point is a start point (S25). If the current target point is not the start point (S25: NO), the CPU 81 sets the needle entry point that is one stitch before the needle entry point that is the current target point as the target point (S26). The CPU 81 moves the process to S31. When the current target point is the start point (S25: YES), the CPU 81 sets the end point as the target point (S27). When the CPU 81 performs the reverse direction search from the needle entry point in the middle of the sewing order, the CPU 81 can search not only from the intermediate needle entry point to the start point but also from the end point to the intermediate needle entry point. The CPU 81 moves the process to S31.

  The CPU 81 performs a code check process for the target point (S31). In the code confirmation process, the CPU 81 confirms whether there is a code associated with the target point. If there is a code, the CPU 81 confirms the code type. The CPU 81 stores the needle entry point whose code has been confirmed in the RAM 83 as the confirmed needle entry point. The confirmed needle entry point indicates the needle entry point subjected to the code confirmation process.

  Based on the result of the code confirmation process (S31), the CPU 81 determines whether or not the target point is a needle drop point associated with the specific type of code stored in the RAM 83 in the code type acquisition process (S13) ( S32). If the target point is not a needle drop point associated with a specific type of code (S32: NO), the CPU 81 refers to the confirmed needle drop point stored in the RAM 83 in S31 and performs code check processing on all needle drop points. It is determined whether there is an unexecuted needle entry point (S33). If there is an unexecuted needle entry point (S33: YES), the CPU 81 returns the process to S21.

  If the target point is a needle drop point associated with a specific type of code in S32 (S32: YES), the CPU 81 moves and displays the cursor 35 (see FIG. 9) to the target point in the needle drop point display area 32A (see FIG. 9). S34). The CPU 81 specifies the target point as the specific point by moving and displaying the cursor 35. The specific point is a predetermined needle drop point associated with a specific type of code. For example, when two or more types of codes are acquired as specific types of codes in S13, the CPU 81 may specify a needle drop point associated with at least one of the two or more types of codes as a specific point. The CPU 81 may specify only the needle entry point associated with any of two or more types of codes as the specific point. Since the editing device 8 does not need to set new information in association with the needle entry point in order to specify a specific point, the information amount of sewing information can be prevented from increasing. The CPU 81 displays information (coordinate information, code, etc.) associated with the specific point in the third area 34. The operator can easily grasp the predetermined needle drop point (specific point) associated with the specific type of code selected in S13 by long pressing the upper key 89A or the lower key 89B and checking the cursor 35. The CPU 81 moves the process to S41 (see FIG. 8).

  When there is no unidentified needle drop point in S33 (S33: NO), the CPU 81 outputs a notification sound indicating that there is no specific point from the speaker 87 (see FIG. 3) (S35). The CPU 81 returns the process to the main process (see FIG. 5).

  Until the CPU 81 determines that the target point is a needle drop point associated with a specific type of code (S32: YES), or for all of the plurality of needle drop points, the needle point is associated with a specific type of code. Until it is determined that it is not a point (S32: NO, S33: NO), the forward direction search or the backward direction search is repeated. Specifically, the CPU 81 sets target points one by one in accordance with the search flag (S23, S24, S26, S27), and repeats the code confirmation process (S31). When there are a plurality of needle entry points associated with a specific type of code, the CPU 81 performs code confirmation processing for all needle entry points until it is determined that the target point is a needle entry point associated with the specific type of code. Therefore, a specific point can be specified reliably.

  6 and 9, an example in which forward direction search is performed for a needle entry point associated with a presser foot code “C” as a specific type of code from a plurality of needle entry points of the sewing information 30 (see FIG. 4). Explained. As shown in FIG. 6, the operator presses the position of the point P4 displayed in the needle drop point display area 32A on the operation panel 88, for example. The CPU 81 moves and displays the cursor 35 at the point P4 (S12). The operator operates the operation panel 88 and selects a presser foot code. The CPU 81 obtains the presser foot code (S13). The operator inputs a first search start instruction to the editing device 8 by pressing and holding the up key 89A. When acquiring the first search start instruction (S14), the CPU 81 starts a forward search.

  The CPU 81 sets the point P4 as the target point (S16). In the case of forward direction search (S21: YES), since the point P4 is not the end point (S22: NO), the CPU 81 sets the point P5, which is one sewing order after the point P4 that is the current target point, as the target point. (S23). The CPU 81 performs a code confirmation process for the point P5 (S31). Since the point P5 is not a predetermined needle drop point (S32: NO), and the points P1 to P4 and the points P6 to P8 have not been subjected to the code confirmation processing (S33: YES), the CPU 81 sets the point P6 as the target point. (S23). Point P6 is a predetermined needle drop point associated with the sewing speed code “A”, but is not a predetermined needle drop point associated with the presser foot code “C” (S32: NO).

  Similarly, the CPU 81 performs code confirmation processing in the order of point P7 and point P8 (S31, S32: NO). When the target point is the point P8 that is the end point (S22: YES), the CPU 81 sets the point P1 that is the start point as the target point (S24). After the code confirmation process for the point P1 (S31, S32: NO), the CPU 81 sets the point P2 as the target point (S23). The CPU 81 performs a code confirmation process for the point P2 (S31). Point P2 is a needle drop point associated with at least the presser foot code “C” (S32: YES). As shown in FIG. 9, the CPU 81 moves and displays the cursor 35 from the point P4 to the point P2, which is a specific point (S34). The CPU 81 displays information associated with the specific point in the third area 34.

  For example, when the operator operates the left key 89C or the right key 89D to select the needle drop points one by one and check the code, it takes time to specify the needle drop point associated with a specific type of code. . In the editing device 8, the operator simply presses the upper key 89A (or the lower key 89B) for a long time, and the point P2 is efficiently used as a predetermined needle drop point (specific point) associated with the presser foot code “C”. Easy to identify.

  As an example, referring to FIG. 6, when searching for a needle drop point associated with the thread tension code “B” as a specific type of code from a plurality of needle drop points of the sewing information 30 (see FIG. 4) in the reverse direction. explain. As shown in FIG. 6, the operator presses the position of the point P4 displayed in the needle drop point display area 32A on the operation panel 88, for example. The CPU 81 moves and displays the cursor 35 at the point P4 (S12). The operator operates the operation panel 88 and selects a thread tension cord. The CPU 81 acquires a thread tension cord (S13). The operator inputs a second search start instruction to the editing device 8 by long pressing the down key 89B. When the CPU 81 obtains the second search start instruction (S14), it starts the reverse search.

  The CPU 81 sets the point P4 as the target point (S16). In the case of reverse search (S21: NO), the point P4 is not the start point (S25: NO), so the point P3 is set as the target point (S26). The CPU 81 performs a code confirmation process for the point P3 (S31). Since the point P3 is not a predetermined needle drop point (S32: NO), and the points P1 to P2 and the points P4 to P8 have not been subjected to the code confirmation processing (S33: YES), the CPU 81 sets the point P2 as the target point. (S23). Similarly, the CPU 81 performs code check processing in the order of the point P2 and the point P1 (S31, S32: NO). When the target point is the point P1 that is the start point (S25: YES), the CPU 81 sets the point P8 that is the end point as the target point (S27). Similarly, the CPU 81 performs code confirmation processing in the order of the points P8 to P4 (S31, S32: NO). After the code confirmation processing of the point P4 (S31), the CPU 81 is not a predetermined needle drop point in which a plurality of needle drop points (points P1 to P8) of the sewing information 30 are associated with specific types of codes (S32: NO). Since there is no needle drop point for which code confirmation processing has not been performed (S33: NO), a notification sound is output from the speaker 87 (S35).

  For example, when the operator operates the left key 89C or the right key 89D to select the needle drop points one by one and check the codes, it is necessary to check the codes for all the needle drop points. It takes time to grasp that there is no associated needle entry point. In the editing device 8, the operator simply presses down the down key 89B (or the up key 89A), and there is no predetermined needle drop point (specific point) associated with the thread tension cord at the points P1 to P8. It can be grasped efficiently and easily by the notification sound.

  As shown in FIG. 8, the CPU 81 refers to the interlocking flag and determines whether or not the instruction acquired in S11 (see FIG. 7) is a non-interlocking mode instruction (S41). When the interlock flag is “0”, the CPU 81 determines that the acquired instruction is a non-interlock mode instruction (S41: YES). The CPU 81 moves the process to S45. When the interlock flag is “1” or “2”, the CPU 81 determines that the acquired instruction is the first interlock mode instruction or the second interlock mode instruction (S41: NO). The CPU 81 determines whether or not the instruction acquired in S11 is a first interlocking mode instruction (S42).

  When the interlock flag is “1”, the CPU 81 determines that the acquired instruction is the first interlock mode instruction (S42: YES). The CPU 81 outputs to the sewing machine 1 a first movement instruction for moving the sewing needle 11 and the cloth relative to each other along a straight line connecting the current needle drop point and the specific point (S43). In the sewing machine 1, when the CPU 101 receives the first movement instruction, the CPU 60 controls the X-axis motor 124 and the Y-axis motor 125 to hold the cloth 60 along a straight line connecting the current needle drop point and the specific point. Is moved with respect to the sewing needle 11. In the editing device 8, the CPU 81 moves the process to S45.

  When the interlock flag is “2”, the CPU 81 determines that the acquired instruction is the second interlock mode instruction (S42: NO). The CPU 81 outputs to the sewing machine 1 a second movement instruction for moving the sewing needle 11 and the cloth relative to each other along the needle drop point in accordance with the sewing order from the current needle drop point to the specific point (S44). In the sewing machine 1, when the CPU 101 receives the second movement instruction, the CPU 101 controls the X-axis motor 124 and the Y-axis motor 125 to hold the cloth along the needle drop point according to the sewing order from the current needle drop point to a specific point. The body 60 is moved with respect to the sewing needle 11. In the editing device 8, the CPU 81 moves the process to S45.

  A specific example of the movement path of the holding body 60 when the sewing machine 1 receives the first movement instruction or the second movement instruction will be described with reference to FIG. Below, the position of the sewing needle 11 with respect to the holding body 60 is shown. The sewing needle 11 is assumed to be at the point P2 as an initial position. The specific point is point P6. When the CPU 101 of the sewing machine 1 receives the first movement instruction, it controls the X-axis motor 124 and the Y-axis motor 125 to hold the holding body 60 that holds the sewing needle 11 and the cloth along the movement path L1 from the point P2 to the point P6. Move relative to each other. The movement path L1 is a straight line connecting the point P2 and the point P6, and is indicated by a one-dot chain line. Since the movement path L1 connects the point P2 and the point P6 with the shortest distance, the sewing machine 1 can quickly move the sewing needle 11 and the cloth relative to each other quickly to a specific point.

  When the CPU 101 receives the second movement instruction, the CPU 101 controls the X-axis motor 124 and the Y-axis motor 125 to move the sewing needle 11 and the holding body 60 holding the cloth relative to each other along the movement path L2 from the point P2 to the point P6. To do. The movement path L2 is connected from the point P2 to the point P6 via the order of the points P3 to P5 according to the sewing order, and is indicated by a solid line. Since the movement path L2 connects the points P2 and P6 along the needle drop points according to the sewing order, the sewing machine 1 can move to a specific point while the operator confirms the actual needle drop points.

  For example, the sewing system 10 may arrange various members (for example, members that press the cloth) in a region other than a line obtained by connecting a plurality of needle drop points of the sewing information 30 according to the sewing order. For example, the sewing system 10 may place a member at a point Q (8, 2) on the movement path L1. When the sewing machine 1 moves the sewing needle 11 and the holding body 60 holding the cloth relative to each other from the point P2 to the point P6 based on the first movement instruction, the sewing needle 11 may collide with a member arranged at the point Q. When the sewing machine 1 moves the sewing needle 11 and the holding body 60 holding the cloth relative to each other from the point P2 to the point P6 based on the second movement instruction, the sewing needle 11 does not collide with a member arranged at the point Q. In the editing device 8, the operator can select which of the first movement instruction and the second movement instruction is output to the sewing machine 1 by inputting the first interlocking mode instruction or the second interlocking mode instruction on the operation panel 88. .

  As shown in FIG. 8, the CPU 81 performs sewing information editing processing (S45). The operator operates the operation panel 88 and the selection key 89 to edit information associated with the specific point. For example, the operator performs coordinate information of a specific point, sewing order, code type change, code deletion, addition, and the like. In the sewing information editing process, the CPU 81 edits the sewing information 30 in accordance with the operator's operation. The CPU 81 returns the process to the main process (see FIG. 5).

  As described above, the editing device 8 can set a plurality of types of codes in association with predetermined needle entry points. The editing device 8 acquires a specific type of code from a plurality of types of codes, thereby specifying a specific point associated with the specific type of code among the predetermined needle drop points. Therefore, since the operator does not need to confirm a plurality of needle drop points one by one, a needle drop point associated with a specific type of code can be efficiently identified from the plurality of needle drop points.

  When the editing device 8 determines that the target point is not a needle drop point associated with a specific type of code, a needle drop point different from the needle drop point set as the target point until the previous time is set as a new target point. Set. Therefore, when there are needle drop points in which a specific type of code is associated with a plurality of needle drop points, the editing device 8 determines that all the needles are determined until the target point is a needle drop point associated with a specific type of code. Since the code check process for the drop point is performed, the needle drop point associated with the specific type of code can be reliably specified.

  If the editing device 8 determines that the target point is not a needle drop point associated with a specific type of code for all of the plurality of needle drop points, it can notify that there is no specific point. Therefore, when the editing apparatus 8 notifies, the operator can grasp that there are no needle drop points in which a specific type of code is associated with a plurality of needle drop points.

  The operator inputs a first search start instruction or a second search start instruction to the editing device 8 using the selection key 89. When the editing device 8 acquires the first search start instruction, the editing device 8 can specify a needle drop point associated with a specific type of code from at least one needle drop point after the sewing order from the current target point. When the editing device 8 acquires the second search start instruction, the editing device 8 can specify a needle entry point associated with a specific type of code from at least one needle entry point whose sewing order is before the current target point. Therefore, the editing device 8 associates a specific type of code from at least one needle entry point after or before the current sewing point in accordance with the acquired first search start instruction or second search start instruction. The needle entry point can be specified.

  The editing device 8 sets the end point as the target point, and when the first search start instruction is acquired, sets the start point as the target point. After determining whether or not the end point is a needle drop point associated with a specific type of code, the editing device 8 follows the sewing order from the start point, and the target point is associated with a specific type of code. It can be determined whether or not it is a falling point. When the editing device 8 sets the start point as the target point and acquires the second search start instruction, the editing device 8 sets the end point as the target point. After determining whether the start point is a needle drop point associated with a specific type of code, the editing device 8 follows the reverse order of the sewing order from the end point, and the target point is a code of the specific type. It can be determined whether or not the needle entry point is associated. Therefore, even when the editing device 8 specifies a needle drop point associated with a specific type of code from a needle drop point in the middle of the sewing order, the target point is associated with a specific type of code for all needle drop points. It can be determined whether or not it is a needle entry point. When there are needle drop points in which a specific type of code is associated with a plurality of needle drop points, the editing device 8 can reliably specify the needle drop points.

  The operator inputs a first interlock mode instruction or a second interlock mode instruction to the editing device 8 using the operation panel 88. When the editing device 8 acquires the first interlocking mode instruction or the second interlocking mode instruction and specifies the needle entry point associated with the specific type of code, the editing apparatus 8 can output the first movement instruction or the second movement instruction. When acquiring the first movement instruction, the sewing machine 1 moves the sewing needle 11 and the cloth relative to each other along a straight line connecting the current needle drop point and the specific point. When the sewing machine 1 acquires the second movement instruction, it moves the sewing needle 11 and the cloth relative to each other along the needle drop point according to the sewing order from the current needle drop point to the specific point. The sewing machine 1 can move to a specific point while an operator confirms the actual needle entry point. The editing device 8 can select the movement path of the sewing needle 11 relative to the cloth from two modes.

  In the above embodiment, the editing device 8 corresponds to the sewing information editing device of the present invention. CPU81 which performs S3 of FIG. 5 is equivalent to a 1st acquisition means. CPU81 which performs S13 of FIG. 7 is equivalent to a 2nd acquisition means.

S34 corresponds to a specific process.

  The present invention can be variously modified from the above embodiment. For example, in the above embodiment, when there is no specific point among the plurality of needle entry points of the sewing information, the CPU 81 outputs a notification sound from the speaker 87 (S35). For example, the editing device 8 may display the notification screen on the display screen 86 without limiting the notification mode to the notification sound. The editing device 8 may include a lamp, and the CPU 81 may turn on or blink the lamp. The CPU 81 may be notified by a notification means such as a speaker provided in a device other than the editing device 8 (for example, the sewing machine 1).

  In the sewing machine 1, when the predetermined needle drop point is sewn, the CPU 101 sews a needle drop point after the predetermined needle drop point according to the code associated with the predetermined needle drop point. The CPU 101 may sew needle drop points after the predetermined needle drop point according to a code associated with the predetermined needle drop point.

  The first movement instruction includes sewing information. That is, the CPU 81 outputs sewing information to the sewing machine 1 every time S43 is executed. The CPU 81 may output the sewing information to the sewing machine 1 in advance when the first interlock mode is set in S11. Since the first movement instruction does not need to include sewing information, the editing device 8 can reduce the capacity of the first movement instruction that is output each time in S31.

  The sewing machine 1 moves the holding body 60 by the X-axis moving mechanism and the Y-axis moving mechanism, thereby moving the cloth clamped by the holding body 60 and the sewing needle 11 back and forth and right and left. The sewing machine 1 may move the sewing needle 11 relative to the cloth 11 held by the holding body 60 and the sewing needle 11 by moving the sewing needle 11 left and right, for example.

  In the sewing system 10, the CPU 101 controls the operation of the sewing machine 1, and the CPU 81 controls the operation of the editing device 8 (executes main processing). Either one of the CPU 101 and the CPU 81 may control the operations of the sewing machine 1 and the editing device 8. For example, the sewing system 10 may omit the control unit 100 and the CPU 81 may control the operation of the sewing machine 1 in addition to the execution of the main process. The CPU 81 may directly control the operation of the sewing machine 1 instead of outputting a movement instruction to the sewing machine 1 in S43 and S44. The editing device 8 may not be a portable terminal, and may be an operation panel of the sewing machine 1, for example. The operation panel may include a display screen, a speaker, an operation panel, a selection key, and the like. In this case, the sewing machine 1 corresponds to the sewing information editing apparatus of the present invention.

  The plural types of cords are not limited to the sewing speed cord, the thread tension cord, and the presser foot cord, and may be two types or four or more types. For example, there is a split cord that stops the sewing operation of the sewing machine 1 for a predetermined time. The editing device 8 is connected to the sewing machine 1 via the cable 70. The editing device 8 may be connected to the sewing machine 1 by a wireless LAN, for example. The editing device 8 does not limit the search method for the specific point (that is, the target point setting method, S21 to S27) to the forward direction search and the backward direction search, and may search by other methods. For example, the CPU 81 may set the target point according to a predetermined rule for the needle entry point (for example, in order of distance from the origin). The specific point search method may be either forward search or reverse search.

  The CPU 81 specifies the needle entry point associated with the specific type of code by moving and displaying the cursor 35 at the target point (S34). The specific mode of the specific point is not limited to this, and the CPU 81 may specify the specific point by, for example, identifying and displaying the specific point with a color different from the color of the other needle drop points. The specific point may be specified by identifying and displaying in a manner different from the light emission manner of the needle drop point. For example, the CPU 81 may identify and display the color, shape, and the like of the cursor 35 for each code type.

  The input means for the first search start instruction, the second search start instruction, the first interlock mode instruction, and the second interlock mode instruction are not limited to the selection key 89 and the operation panel 88, respectively. May function as
