Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic sewing slitter which moves a sewing object level 5 relative to a lower moving position on a boring needle to form a predetermined shape of the sew. Background of the invention

First, it is known that a slit-like automatic sewing machine for forming a predetermined shape 10 on a cloth while moving the holding member for holding the cloth in the horizontal direction with respect to the downward movement position of the needle. The automatic sewing machine (10) has a moving mechanism that is provided with a motor (X-axis motor, Y-axis) that is driven in two directions perpendicular to the horizontal plane (X-axis direction, γ-axis direction). motor). As a general rule, the automatic sewing machine moves the moving mechanism to a phase in which the sewing needle does not penetrate into the sewing material, that is, a period in which the needle is ascended, after the needle is pulled out, and when the lower needle is lowered into the sewing material. Usually, the upper limit of the maximum speed of the sewing is determined by the feeding distance at which the sewing material is moved at a predetermined interval. Therefore, as long as the limit value is within the limit value, the movement of the sewing object is controlled, and the sewing needle is not stabbed. The movement of the moving mechanism is completed during the sewing. Further, a sewing machine for outputting a movement command for correcting the start delay of the moving mechanism and speeding up to the start of the start is known. When the movement point of the moving mechanism is deviated, the sewing needle does not move from the sewing object (4) before the sewing starts, and the sewing material starts to move when the sewing needle is sewn in the sewing state. Therefore, the sewing needle is moved by the sewing machine 3 200938680 When it is pulled, it is lowered in a state of being bent, and a so-called needle shift occurs, whereby it is impossible to capture the needle thread by the hook. 'There is a situation in which a so-called jump stitch is generated, or the needle is engaged with the sewing machine part to damage the needle tip and damage the fiber of the fabric. Further, when the sewing needle penetrates the sewing material, the sewing material starts to move, whereby the through hole of the sewing material 5 becomes large, the residual mark, or the stitch position is shifted, and the product quality is lowered. For this reason, for example, as disclosed in Patent Document 1, there is known a sewing machine which detects the rotation speed of the spindle of the sewing machine by detecting the spindle rotation speed of the sewing machine when the spindle rotation speed of the sewing machine is high speed and when moving the movement mechanism at a low speed. 10 and according to the rotation speed, the spindle phase of the movement of the starting movement mechanism is changed to prevent the needle from shifting. [Patent Document 1] Japanese Patent Laid-Open Publication No. 2000-279666

SUMMARY OF THE INVENTION PROBLEMS TO BE SOLVED BY THE INVENTION The object to be solved by the invention is that the movement mechanism reaches the command. The sewing machine of Patent Document 1 cooperates with the spindle rotation speed of the sewing machine, and only changes the movement start point of the moving mechanism. However, when the holding member (pressing foot) for holding the sewing material of the moving mechanism is changed, the acceleration changes due to the change in the total amount of the moving mechanism, so that the time for starting the movement of the driving horse moving mechanism to the moving mechanism is changed, and the movement is changed. The time from the amount of movement to the time of stopping changes.

After a sewing, the moving mechanism moves to produce a needle shift. Further, the movement & the time until the start of the operation becomes longer than the presser foot change 200938680. The needle is moved before the needle is completely pulled out of the sewing material, and is shifted, so that the patent document 1 also generates Previously the same problem. If you can get a good sewing product, you can't judge it if you can't get a good sewing product in the case of a real money _ condition (changing the seam, or posting a chat). Although the information of the problem can be obtained only by performing the seam sewing and the needle of the trial sewing, the condition of changing the rotation speed of the slit (four) is

(4) Repeated trial joints repeatedly to reduce production efficiency. x, there is a defective product in which the sewn product is produced every time, and it is costly to dispose of the sewn product which is accompanied by the sewing. The object of the present invention is to provide an automatic sewing and slitting machine capable of providing an effective information for the problem of the influence of the quality of the product by using the needle (4) of the slashing needle as the response of the time and the moving structure. In addition, the speed of the sewing with the self-sufficiency is reduced to a minimum. The invention is directed to the invention of the first aspect of the invention. The invention relates to an automatic sewing machine, which has a needle bar, which is mounted with a needle and moves up and down with respect to the rotation of the main shaft to move the moving mechanism up and down. The needle bar moves on the horizontal plane perpendicular to the vertical direction of the needle bar. The sewing machine rotates the spindle, the driving motor drives the moving mechanism, and the control mechanism controls the driving motor. And the first Μ ' 峨 峨 峨 峨 峨 峨 峨 峨 峨 峨 峨 峨 峨 峨 峨 峨 峨 峨 峨 峨 峨 峨 峨 峨 峨 峨 峨 峨 峨 峨 峨 峨 峨 峨 峨 峨 峨 峨 峨 峨 峨 峨 峨 峨 峨 峨 峨 施 施The speed is set by the needle bar 5 200938680 10 15 and the moving mechanism, and the sewing machine is provided. The first detecting mechanism is provided to detect the rotation angle of the main shaft, and the second detecting mechanism is detected. a position of the moving mechanism; the second memory means is configured to drive the shift when the position command of the moving mechanism of the sewing material is stored, and the first detecting machine is used every predetermined time The spindle rotation angle detected and the movement mechanism position detected by the second detection mechanism; = the time calculation means calculates the movement of the movement mechanism by the movement of the movement position of the second record The required time is calculated based on the calculation result of the time required to calculate the operation of the mechanism by the operation time of the operation time of the operation time of the machine (the calculation of the rotation speed of the sewing machine motor; the operation opening: the angle: the outlet mechanism is based on the aforementioned operation time) Calculating the result of the operation of the mechanism, and calculating the starting angle of the movement of the moving mechanism, based on the sewing distance (4), the number of stitches, and the main speed = the needle bar and the moving mechanism are operated according to the previous month. The calculation result of the rotation speed of the motor of the front-end machine, and the calculation result of the operation start angle of the mechanism of the operation start angle calculation means obtained by the previous == machine In the above-described "motor", the "moving mechanism starting angle" refers to the angle of rotation of the main shaft when the moving mechanism starts operating. The invention of the second application of the patent scope is in the automatic sewing sewing machine of the towel, and the white person relates to the structure of one item, that is, the display unit corresponding to the display of the following is the same as the display unit according to the speed calculation mechanism. The slitter motor 20 200938680 is purely placed, according to the movement start angle of the moving mechanism of the second-degree disengagement mechanism by the predetermined time. "Corner 10, the invention of the third item is in the automatic sewing machine of the second application of the patent application, including the surface that can be connected to an external computer, and the aforementioned moving mechanism of the mechanism by the aforementioned action time calculation mechanism The calculation of the time required for the operation is performed by the calculation of the rotational speed of the sewing motor by the speed calculation means and the calculation of the operation start angle of the movement mechanism by the operation start angle calculation means via the interface According to the invention of the first aspect of the invention, the time required for the operation of the movement mechanism of each of the needles calculated by the operation time calculation means is calculated, and the calculation of the speed 15 calculation means is appropriate for the time. The rotation speed of the sewing machine motor, that is, the sewing speed. Further, the calculation of the operation time of the moving mechanism by the operation time calculation means and the calculation of the rotation speed of the sewing machine motor by the speed calculation means are performed on the sewing data. Before the sewing operation, the first inspection mechanism and the second inspection agency are inspected every predetermined time. The calculation result of the rotation angle of the spindle 20 and the movement mechanism, and the calculation results of the operation time calculation means, the speed calculation means, and the operation start angle calculation means are stored in the second storage means. Therefore, after the sewing work of the sewing data is once performed 'When the sewing machine is operated in accordance with the operating time of the moving mechanism of the second memory mechanism and the rotational speed of the sewing machine motor during the sewing operation of the sewing data, the sewing machine can be used to eliminate the movement of the moving mechanism before the needle is pulled out from the sewing material. Or the needle shift occurs when the needle is stabbed, thereby eliminating the needle shift caused by the moving mechanism before the needle is pulled out from the workpiece, thereby causing the sewing to deteriorate or the seam to be sewn. The problem of deterioration of the seam product such as the enlargement of the through hole and the stitching/positional deviation. Therefore, the sewing product of the sewing product can solve the needle shift caused by the movement of the moving mechanism after the needle is inserted into the sewing object. The problem of the needle bending. Therefore, the reliability of the seam rushing machine is increased by two. The degree calculating means automatically calculates an appropriate sewing machine horse, the rotation speed, and the movement start angle of the movement mechanism corresponding to the movement of the sewing object, and the second memory structure is used to automatically perform the sewing speed of the sewing machine. Setting the movement start angle of the moving mechanism can solve the needle shift of the sewing problem of the corresponding moving mechanism due to the sewing speed of the manual Η = lowering machine 33 in the prior art. Compared with the prior art, the setting of the sewing speed for preventing the needle shift and the starting angle of the movement of the moving mechanism can be performed very easily. Further, the following problem can be solved, that is, the needle of the sewing product problem caused by the moving mechanism Offset, in the prior art, since the operator does not give any response state of the needle bar movement point and the moving mechanism of the sewing machine, it is impossible to find an effective solution, and the countermeasure method only changes the rotation speed of the sewing machine. The reliability of the slitting machine can be improved. In addition, since the appropriate sewing speed is automatically calculated, it is possible to solve the problem that the assisting machine has to be operated a plurality of times in the prior art until it is found that the sewing speed is suitable for sewing, and the preparation time for the sewing operation can be shortened, and the work of 200938680 can be improved. effectiveness. In addition, the cost of the appropriate sewing speed is found in the prior art/the prior art: seam: the needle bending caused by the machine trial sewing or the movement of the sewing machine is removed. Memory is explained by the position of the second inspection sewing operation. This can be used to sew materials.

In other words, the performance requirement of the operating time calculation means can be set low, and the cost of the operating time calculation means can be reduced.

Further, the second memory means memorizes the rotation angle of the spindle detected by the i-th detecting means every predetermined time. Thereby, the rotation speed of the sewing machine motor can be calculated by the speed calculation means after the sewing operation of the sewing data is completed. That is, the speed calculation means does not need to immediately calculate the position of the movement mechanism detected by the second detection means. Therefore, even if the speed calculating means does not have the performance of immediately calculating the position of the moving mechanism detected by the second detecting means, the rotational speed of the rush motor can be calculated. In other words, the performance requirement of the speed calculating means can be set low, and the cost of the speed calculating machine 20 can be reduced. Further, in the second memory mechanism described above, the rotation angle of the main axis is memorized every predetermined time. Therefore, the operation start angle β of the movement mechanism can be calculated by the operation start angle calculation means after the completion of the sewing operation, and the operation start angle calculation means does not need to be checked by the first detection mechanism. The rotation angle of the main shaft and the position of the moving mechanism detected by the second check structure are immediately calculated. Therefore, even if the operation start angle calculation means does not have the performance of calculating the rotation angle of the main shaft detected by the first detection means and the movement mechanism position detected by the second detection means, It is also possible to calculate the starting angle of the movement of the moving mechanism. In other words, the performance requirement of the operation start angle calculating means can be set low, and the cost constituting the operation start angle calculating means can be lowered.

The response X of the mobile unit 10 is chased toward the X-axis command position P after the stop, and oscillates toward the target position B after the target position B is vibrated. When the response of the moving mechanism 10 converges to the target position B, the calculation subtracts the offset 10 of the x-axis detection position q (response signal) of the moving mechanism 10 from the X-axis command position P, as long as the deviation ERR is ±dP In the range, even if the sewing needle is stuck to the sewing object, the error range is not allowed. Even if the fork shaft detecting position Q of the moving mechanism 1 converges within the stable range of the X-axis command position p, the moving mechanism 10 is also completed. The movement of the target position B. Here, the above description will be made by taking the xenon motor 12 and the shaft position sensor 13 as an example. However, since the spindle motor 14 and the shaft position 15 are disposed in the same manner, the sensor 丨5 is omitted. Description. At this time, after the command position P for driving the moving mechanism 10 is output, and the next time the sewing needle is stuck to the sewing object, the movement required for the vibration action of the moving mechanism 10 to converge is required. The time is the stabilization time TS, and the operation time calculation means 56 calculates the above-described stabilization time Ts. The stabilization time of the moving mechanism 10 calculates both the X-axis and the γ-axis. (Speed Calculation Mechanism) The speed calculation means 57 calculates the appropriate rotation speed of the slit motor 5 in accordance with the stabilization time Ts calculated by the operation time calculation means 56. Fig. 5 is a view showing the correspondence between the point when the needle 2a is lowered and the movement point of the moving mechanism 10 when the sewing machine motor 5 is rotated at the same time when the sewing machine is pulled out. Further, Fig. 5(a) shows the corrected stitches driven by the rotational speed of the sewing machine motor 5 by sewing the data, and the corrected stitches driven by the rotational speed of the sewing machine motor 5 calculated by the speed calculating means 57. FIG. 5(b) is an enlarged explanatory view of a portion Z of the fifth (a) diagram, in which the relationship between the downward movement point and the movement point of the moving mechanism 1 is performed. The curve Η and I of Fig. 5 show the transition curve of the downward movement position above the needle 2a of the sewing material. The curve w of Fig. 5 is shown on the curved line 10 of the detection position of the moving mechanism 1〇 under the same time axis as the curve Η and the curve I. The curve of Fig. 5 shows the transition of the lower position of the needle 2& before the correction, and the curve I shows the needle 2& after the correction (driven by the rotational speed of the sewing machine motor 5 of the speed calculating mechanism 57). The curve of the migration above the lower position. The needle bar 2 moves up and down in accordance with the rotational speed of the sewing machine motor 5, and the needle 2a 15 repeats the action of piercing and pulling out the sewing object. In the above-described curve 第 shown in Fig. 5, the needle 2a is inserted into the section of the sewing material while the needle 2a is lowered from the upper position G of the sewing object. The period in which the needle 2a rises from the upper position G of the sewing object is the section in which the needle 2a is pulled out from the sewing material. At this time, the time required for one of the spindles 7 to rotate is the time Ta, and the sewing machine motor 5 is controlled such that the time required for one of the spindles 7 to rotate is 20 for the time Ta. On the other hand, the moving mechanism 10 operates as the curve w. At this time, when the needle 2a is stuck at the sewing object, the moving mechanism 1 has a needle shift due to the stable position of the feeding position Wa exceeding the target position B when the needle passes. Therefore, as shown in Fig. 5, the sewing speed at which the needle shifts in the range of the target position B due to the vibration of the stop mechanism 200938680 is not set, that is, the setting is based on the sewing needle 2a from the sewing material. The rotational speed of the sewing machine motor 5 of one of the spindles 7 of the extracted section is rotated by the time Tb. Thereby, as shown by the curve I after the time when the needle 2a is stuck to the sewing object, when the needle of the moving mechanism 10 passes through, the position of the 5 cloth is in the stable range of entering the target position B, so that the needle is not bent. The needle offset for the cause of the problem. The speed calculating means 57 calculates the rotational speed of the sewing machine motor 5 for setting the time Ta for rotating the main shaft 7 to the time Tb at which the needle shift is not generated. Fig. 6 is a view showing the correspondence between the rotation angle of the main shaft 7 and the lower moving position 10 on the needle 2a. 15 20 As described above, when the spindle 7 is rotated, the needle bar 2 is moved up and down. As shown in Fig. 6, the downward movement position of the needle 2a has a certain relationship with the rotation angle of the main shaft 7. For example, as shown in Fig. 6, when the position of the needle bar 2 is the top dead center, the rotation angle of the main shaft 7 is the twist, and when the position of the needle bar 2 is the bottom dead center, the rotation angle of the main shaft 7 is 18 degrees ' The angle of the bee 2a when the needle 2a is pulled out from the sewing material at the point of the point of the beak 7 is the angle 0b at which the sewing material is turned to the position on the needle plate of the holding portion 11 of the moving mechanism 10 and the thickness of the sewing material. When the needle 2a is punctured at the time point Hb of the sewing material, the rotation angle of the spindle is produced, and the sewing material is mixed with the needle plate of the (4) part of the moving machine lion = = the angle at which the thickness of the object is added. Usually, the aforementioned rotation angle 0a of the main shaft 7 is set to be the same as the above-described rotation angle. The angle is, for example, in the cloth thickness input sewing data, or with the sewing data &, ^ degree 21 200938680 ^l=18〇M0a+0b) (1) The measured stabilization time Ts is due to the rotation between the spindles. The minimum time, the time Tb at which the maximum rotational speed of the spindle 7 is -rotated is calculated by the following formula (2). 5 Tb==Tsx360°/0 1 (2) The time of rotation of one of the spindles 7 of the equation (2), and the rotational speed N [ rpm] of the spindle 7 is calculated by the following equation (3). N=60/Tb (3) The rotation speed of the slit machine motor 5 is the same as the rotation speed n of the equation (3). Thereby, the rotational speed of the motor 5 is calculated. Here, when the maximum rotational speed N [rpm] of the spindle 7 calculated from the measured stabilization time Ts is larger than the rotational speed of the slit machine motor 5 of the sewing data, the lowest axis is selected by the sewing control program of the rib machine. The machine rotation speed & value (the highest rotation speed value limited by each condition) is sewn. The speed calculation means 57 calculates the rotational speed of the sewing machine motor 5, and after reading the sewing operation of the sewing data, reads the spindle encoder 6 and the spindle position sensor axis position stored in the EEPROM 24 every predetermined time.资料 The information of the sensor 15 is calculated as described above. Further, when the processing time of the mm of the control device of the slitting machine has a margin, it may be calculated during the slitting operation of the sewing data. (Operation start angle calculation means) The operation start angle calculation means 58 is based on the movement mechanism 10 detected by the X-axis position sensor 13 and the x-axis position sensor 15 based on the movement mechanism of the sewing (4). The position and the rotation angle of the main shaft 22 200938680 shaft 7 detected by the spindle encoder 6 are used to calculate the movement start angle 0 start of the movement mechanism 1 in each needle. Fig. 7 is a view showing the movement of the moving mechanism 1 driven by the sewing data before the correction by the operation start angle, and the correction of the operation start angle driving of the moving mechanism 10 calculated by the operation start angle calculation unit 5; A diagram illustrating the correspondence between the point of movement of the needle 2a and the point of movement of the moving mechanism 1〇. The curve 第 of Fig. 7 shows the transition of the lower moving position of the needle 2& The curve hip and curve WA of Fig. 7 are shown as curves of the detection position of the moving mechanism 1〇 under the same time axis as the curve Η. The curve W of Fig. 10 is a curve showing the transition of the detected position of the moving mechanism 1〇 before the correction, and the curve WA is displayed after the correction (the starting angle of the moving mechanism 1 by the motion start angle calculating mechanism 58) The curve of the migration of the detected position of the moving mechanism 10 is driven. The operation start angle calculation means 58 sets the movement start angle of the movement mechanism 10 so that the movement mechanism 1 开始 starts to operate from the time point Ha before the needle is pulled out from the sewing material 15. That is, when the moving mechanism 1 is driven by the sewing data, the operation start angle 0 start is set, and the operation start angle 0 is cut and equal to the angle of the movement start angle when the movement mechanism 10 is driven by the sewing material, and the angle difference is obtained. The angle difference is the spindle 7 when the movement mechanism 10 starts moving from the detection position of the moving mechanism 1 and the rotation angle 0 A of the spindle 7 detected by the spindle encoder 6 and the time when the needle 2a is pulled out from the sewing material 7 Rotation angle <9 B difference. When the operation start angle when the movement mechanism 10 is driven by the sewing material is 0, the operation start angle 0 start is calculated by the following formula (4). 〇start= Θ 0+( Θ^-ΘΚ) (4) 23 200938680 The calculation of the operation start angle 0 by the operation start angle calculation means 58 is performed after the sewing operation of the sewing data is finished. The above calculation is performed by reading the data of the spindle encoder 6, the spindle position sensor 13 and the spindle position sensor 15 which are stored in the EEPROM 24 every predetermined time. In addition, when the processing time of the CPU 21 of the sewing machine control device 2 has a margin, it may be calculated during the sewing operation of the sewing data. Further, the operation time calculation means 56, the speed calculation means 57, and the operation start angle calculation means 58 are based on the sewing data stored in the EEPROM 24 by the CPU 21 of the control device 2, and the sewing operation based on the sewing data. The position of the moving mechanism 10 detected by the position sensor 13 and the Y-axis position sensor 15 and the rotation angle of the spindle 7 detected by the spindle encoder 6 are calculated. At this time, the position of the moving mechanism 10 detected by the X-axis position sensor 13 and the γ-axis position sensor 15 is read by the X-axis position sensor 13 and the Y-axis position every predetermined time. The position of the moving mechanism 10 of the EEPROM 24 as the second memory means at the position of the moving mechanism 10 detected by the sensor 15. Further, by the rotation angle of the spindle 7 detected by the spindle encoder 6, the rotation angle of the spindle 7 of the EEPROM 24 in which the rotation angle of the spindle 7 detected by the spindle encoder 6 is stored every predetermined time is read. (Second memory means) The second memory means 52 stores the spindle rotation angle of the spindle encoder and the position of the movement mechanism 10 detected by the X-axis position sensor 13 and the Y-axis position sensor 15. And the calculation results of the operation time calculation means 56, the speed calculation means 57, and the operation start angle calculation means 58. Specifically, the sewing machine motor 5 of the control device 20 detects the rotation angle of the spindle 7 of the main shaft 7 detected by the spindle encoder 6 and the movement mechanism 10 detected by the X-axis position sensor 13 by the X-axis position sensor 13 The position in the X-axis direction and the Y-axis direction of the moving mechanism 10 detected by the Y-axis position sensor 15 by the Y-axis motor 14 are stored in the EEPROM 24. Further, the control device 20 is stored in the EEPROM 24 by the stabilization time calculated by the CPU 21, the rotation speed of the sewing machine motor 5 corresponding to the stabilization time, and the operation start angle 0'. Therefore, the EEPROM 24 described above functions as the second memory means 52. ^ Further, the rotation speed and the movement start angle of the sewing machine motor 5 corresponding to the stabilized time of the memory are memorized in such a manner as to identify which sewing material is corresponding. (Sewing Control Mechanism) The sewing control mechanism 55' is sewn by the calculation result stored in the second storage mechanism 52 when the sewing operation is performed by the sewing material. In other words, when the sewing operation is performed by the sewing data, the sewing machine motor is driven by the rotation speed of the calculation result of the calculation result 57, and the movement calculation means 56 and the operation start angle calculation means 58 are operated. The calculation result stabilizes the time and the start angle of the motion, so that the moving mechanism performs the sewing operation. After the sewing operation of the sewing data is once +, the rotation speed of the sewing machine motor 5 calculated by the speed mechanism 57 can be calculated based on the movement time of the movement mechanism 10 of the operation time calculation mechanism 56. < The operation start angle of the moving mechanism 10 calculated by the calculation unit 58 causes the sewing machine 1 to operate. The sewing control unit 55 reads the calculation result of the sewing data stored in the EEPROM 24, the % and the operation time calculation means 56, the speed calculation means 57, and the operation 25, 200938680, and the calculation result of the angle calculation means 58 into the CPU 21 of the control means. And it works. (Display Mechanism) Fig. 8 is an explanatory view showing an example of the display screen of the operation panel display 4. The operation panel display 4 can respectively display the downward movement position of the needle bar for each predetermined time according to the sewing speed of the sewing machine after the sewing speed of the sewing machine motor is increased or decreased by the sewing control mechanism 55. The position of the movement mechanism for each predetermined time required for the movement of the movement mechanism calculated by the operation time calculation means 56, and the movement start angle of the movement mechanism calculated by the operation start angle calculation means #1. That is, as shown in Fig. 8, the corresponding relationship between the lowering position of the needle 2a of the sewing machine and the lowering position of the needle 2a and the movement of the moving mechanism 1 can be visually grasped on the same time axis. Thereby, the effect of the calculation result of the sewing machine motor rotation speed by the speed calculation means 57 and the operation start angle calculation means 58 can be visually grasped when the sewing machine 15 is operated. Thereby, the operation panel display 4 functions as a "display mechanism". Further, the operation panel display 4 is a sewing needle that rotates at a speed based on the sewing machine motor 5 between the movements of the moving mechanism 1 . The upper downward movement position and the movement start angle of the movement mechanism 10 are in a state corresponding to each other on the same time axis, and the operation panel display 4 of the control device 20 is not displayed. In addition, the PCMG can also move down the needle bar for each predetermined time of the sewing machine sewing speed by increasing or decreasing the rotation speed of the slit machine motor according to the sewing control mechanism 55 controlled by (4) 2 (). The position, the predetermined time period according to the time required for the movement of the movement mechanism calculated by the operation time calculation means 56, the position of the movement mechanism, and the movement start angle of the movement mechanism calculated by the operation start angle calculation means 58 It is displayed on the monitor 41 similarly to the operation panel display 4. (Operation of sewing machine) 5 The operation of the sewing machine 1 will be described in detail below. The operation of the sewing machine 1 measures the spindle rotation angle detected by the spindle encoder 6 by the spindle encoder 6, and the position of the moving mechanism 1 detected by the spindle position sensor 13 and the spindle position sensor 15. When you select the measurement mode, the sewing action is performed. Figure 9 is a diagram showing the sewing machine operation and the 10 action flow when the measurement mode is selected. The first diagram shows the processing contents of the processing routine for measuring the timing interrupt. First, when the user selects the measurement mode (step S1), the sewing machine 1 measures the spindle rotation angle detected by the spindle encoder 6 by the X-axis position sensor 13 and γ in addition to the general sewing operation. The measurement mode of the position of the moving mechanism 1 detected by the axis position sensor 15 15 operates. When the sewing machine 1 is driven in the measurement mode, if the needle is displaced, there is a possibility that the sewing needle 2a is bent or the seam is reduced in the shape of the seam, and the possibility of discarding the sewing material is generated. The sewing operation is performed. Next, the operator 20 selects the sewing material via the display and input of the operation panel display 4. Then, the operator operates the pedal 3 (step S2)' to control the device 20 to perform the saving of the data (step S3), and then permits the interruption of the measurement timing to start the measurement timing (step S4). Thereafter, the sewing machine 1 starts the sewing operation based on the selected sewing data (step S5). When the sewing operation starts in the measurement mode, an interrupt signal is generated for each measurement timing of the 27 200938680 count cycle, and the processing of the measurement timing interrupt shown in Fig. 10 is executed. [Control County 2G reading by the spindle The spindle rotation angle detected by the encoder 6, the position of the moving mechanism 1 detected by the X-axis position sensor 13 and the ¥axis position sensor 15, and the value of the data and the meter 5 are memorized. EEPR 〇 M24 (step S6). When the sewing operation based on the sewing data is completed (step S7), the control device 2 禁止 prohibits the interruption of the measurement timing and stops the operation of the measurement timing (step S8). Thereafter, the CPU 21 of the control device 20 reads the spindle rotation angle stored in the EEPROM 24, the position of the moving mechanism 10, and the measured count value, and calculates the movement mechanism 10 from the 10 measurement count value, the spindle rotation angle, and the position of the moving mechanism 1〇. The stabilization time Ts, the highest rotation speed N of the sewing machine motor 5 corresponding to the stabilization time Ts, and the movement start angle 0stan of the movement mechanism 1 ,, the stabilization time Ts, and the sewing machine motor 5 corresponding to the rotation speed N of the spindle 7 The rotation speed and the operation start angle 0 start are memorized in the EEPROM 24 (step S9), and the operation of the measurement mode is completed. When the operation of the measurement mode is completed, when the user selects the display result of the calculation result by the operation panel display 4, the steady-state time T and the rotational speed N of the spindle 7 are displayed on the operation panel display 4 by the cpu 21 of the control device 2. And a correspondence relationship between the downward movement position of the needle 2a corresponding to the movement start angle 0 start and the position of the movement mechanism. Then, the user selects the normal sewing mode, and when the sewing operation is performed by the sewing material, sewing by the sewing control mechanism 55 is performed. In other words, the CPU 21 of the control device 20 performs the sewing operation for operating the respective parts of the sewing machine based on the highest rotation speed N of the sewing machine motor 5 and the operation start angle 0 200938680 start corresponding to the stabilization time Ts stored in the EEPROM 24. Thereby, the sewing operation of the sewing material can be performed without causing a problem of deterioration in the quality of the red seam product and needle bending caused by the needle shift. (Effect of the sewing machine of the present invention) 5 ❹ 10 15 ❹ 20 "In the above-described embodiment, when the sewing operation is performed by sewing the data, the moving time TG of the moving mechanism ig calculated by the operating time calculating means 56, The rotation speed of the main shaft 7 calculated by the speed calculation means 57, the rotation speed of the money motor 5, and the operation start angle calculated by the operation start angle calculation means 58 are stored in the second storage means 52. Then, when the sewing operation is performed by the sewing data, the sewing control mechanism 55 drives the slit, the motor 5, at the rotational speed of the inspection motor 5 of the second rhyme structure 52, and follows the trending time. And the movement start angle Θ start causes the moving mechanism 1 to operate. Thereby, the time point after the needle is pulled out from the sewing material and the time before the needle 2a is stabbed in the sewing object, and the movement time of the moving machine Tsit is appropriately controlled. Therefore, it is possible to eliminate the occurrence of a needle shift due to the movement mechanism licking the needle 2a before the needle is pulled out from the sewing object or the point-in-time operation after the needle is stabbed by the sewing needle, thereby eliminating the movement mechanism of the needle from the needle. Sewing When the needle is displaced before the object is pulled out, the sewing process is deteriorated, the seam is not enlarged by the through hole of the sewing material, and the position of the seam is deviated, and the sewing product quality is deteriorated. Therefore, the sewing product quality is improved. Therefore, the problem that the needle is bent due to the needle shift of the moving mechanism after the needle punching into the sewing object can be solved. Therefore, the reliability of the sewing machine is improved. Further, as described above, the operation time calculating means 56 and The speed calculation means 57 automatically calculates the rotation speed of the appropriate sewing machine motor 5 corresponding to the sewing machine movement 29 200938680 by the movement of the moving mechanism 1 and stores it in the second storage mechanism 52. Thereby, the sewing machine can be automatically executed. The setting of the sewing speed and the starting angle of the movement mechanism can solve the problem that the operator in the prior art manually cuts the sewing speed of the sewing machine and causes the problem of the sewing product due to the feeding of the corresponding moving mechanism. Therefore, the setting of the sewing speed for preventing the needle shift and the starting angle of the movement mechanism can be performed very easily and surely compared with the prior art. The next problem is the needle shifting of the sewing problem caused by the feeding of the moving mechanism. In the prior art, since the operator has not given any sewing machine needle bar action point and the moving mechanism response state. It is impossible to find an effective solution, and the countermeasure method only changes the rotation speed of the sewing machine, so that the reliability of the sewing machine can be improved. Moreover, it can be solved in the prior art that the setting of the sewing speed cannot be made dependent on the operator's rule of thumb. The problem of the universal solution makes the reliability of the sewing machine even higher. In addition, since the appropriate sewing speed is automatically calculated, it is possible to solve the sewing machine to be actuated multiple times in the prior art until the sewing speed suitable for sewing is found. It is a very time-consuming problem, which can shorten the preparation time and time of sewing work and improve work efficiency. Further, it is possible to reduce the cost of the needle bending 20 or the disposal of the sewing material which is produced when the sewing machine is tested in the prior art until the appropriate sewing speed is found. Further, the rotation angle of the main shaft 7 and the position of the moving mechanism ίο at the time of the sewing operation based on the sewing data are memorized in the EEpR 〇 M24 every predetermined time. Therefore, regarding the calculation of the stabilization time □8 by the operation time calculation means 56, the sewing machine 30 corresponding to the rotation speed N of the main shaft 7 of the speed calculation means 57 200938680 5 ❹ 10 15 10 20 rotation of the motor 5 Various calculations such as the speed difference and the calculation of the operation start angle 6»start of the operation start angle calculation means 58 can be performed after the sewing operation is completed. In other words, it is not necessary to perform the calculation processing in advance for the various calculations. Therefore, even if the CPU 21 of the control device 20 does not have the performance of immediately calculating the position of the moving mechanism detected by the spindle encoder 6, the various calculations can be performed. That is, the performance requirement of the CPU 21 of the control device 2 can be set low, and the cost can be lowered. Further, the operation panel display 4 displays the downward movement position of the needle 2a at the rotation speed of the sewing machine motor 5 corresponding to the rotation speed N of the spindle 7 which is appropriately calculated for the movement time Ts of the movement mechanism 1A, and starts the operation. The angle 0 start starts to move, and the position of the moving mechanism 1 动作 is stabilized by the time Ts. Thereby, the effect of preventing the needle shift by the sewing control mechanism 55 can be visually grasped before the sewing machine 1 is sewn. Therefore, the operator can more clearly grasp the movement of the sewing machine. (Others) In the above embodiment, the operation time calculation means 56, the speed calculation means 57, and the operation start angle calculation means 58 are activated by the calculation of the CPU 21 of the control device 20 of __, but The calculation of the external PC 40 is performed. Further, the monitor 41 in the above embodiment is the monitor 41 of the PC 40, but a dedicated display device may be separately used. Further, the implementation of the present invention is not limited to the sewing machine i in the above-described embodiment, and the movement mechanism operates in the horizontal plane perpendicular to the vertical movement with respect to the needle bar, and the (four) movement mechanism operates based on the sewing material 31 200938680 Sewing the seams can be used for any seams.
