Abstract

To provide an electronic sewing machine capable of carrying out condensation stitching of high quality in a predetermined pattern prior to or subsequently to a needle oscillating pattern reliably through a simple method. A predetermined needle oscillating pattern is selected in accordance with condensation stitching formed at the start or end of needle oscillating pattern. The number Pn of condensation stitching operations is set during condensation stitching (S113), and the number of condensation stitching is calculated by multiplying the number Pn of condensation stitching operations by the number N of stitches with one needle oscillating pattern of condensation stitching (S114). In the case in which the number of stitches is simply set, there is a possibility that the condensation stitching might be ended in the middle of a needle oscillation and a normal sewing start position might be shifted. In the case in which the number of stitches is calculated as above, the condensation stitching is always completed at the end of the needle oscillation thereof, and then the normal stitching is started. Therefore, a sewing shift is not generated during a transition between the normal needle oscillating pattern and the needle oscillating pattern for the condensation stitching. Thus, the quality of sewing can be enhanced.

Tooth seams are sewn into the cloth. [Known technology] In the conventional slat sewing machine, the rotary vibrating needle cam is used to link the main shaft of the sewing machine, and the vibrating needle mechanism is operated to make certain vibrating needle patterns occur, but there are more vibrating needle patterns. Later, due to this, a vibrating pin cam must be made, and the exchange of the vibrating pin becomes quite complicated. In addition, the problem that the manufacturing cost of the cam becomes larger and larger will occur. For this reason, in recent years, the vibrating needle pattern is used as a data memory, and the pulse motor that drives and controls the amount of vibrating needles is understood based on the 2 readings of the vibrating needle pattern data. [Problems to be Solved by the Invention] However, in such a conventional electronic zigzag sewing machine, 'the sewing machine cannot be changed or a new vibrating needle pattern must be created, and it is necessary to use a coordinate input device and a lean material creation device such as a personal computer to make or change it. , But need to prepare a separate data creation device, thus reducing its adaptability. In addition, in the conventional electronic zigzag sewing machine, in order to prevent the dissolution of the seam during the start or end of sewing, the stop stitching is performed by setting the number of stitches at the beginning or end of the stop stitching in a certain zigzag stitching style. Start or finish setting the seam stop pattern. Moreover, since the number of stitches at the beginning or end of the stop stitching is not used, the position of the vibrating stitches at the beginning or end of the stop stitching is not important.

AT B7 V. Description of the invention (In the middle, it is sewn with 12 or 24 stitches according to the three-day moon pattern. The type of transport has three types: "standard, three months, and equal". In addition, there are The left and right provisions of the crescent button are generally referred to as the right crescent button when the crescent side of the initial sewing machine is placed on the top of the right arc, and the opposite side is referred to as the left crescent button. The blind stitching is as shown in Figure 5 (c). At the beginning of sewing, linear sewing is performed. The last stitch of the number of stitches is 2 stitches, and the vibrating stitch is at the width of the vibrating stitch (Nw). Return to the original position and repeat the pattern. In this case, there are left and right concealed stitches depending on the direction of the vibrating needle. The right (left) concealed stitches are made from straight stitches to the right (left). Conventional style is the original style made arbitrarily. [Inherent information] Each of the above-mentioned vibrating needle styles has a vibrating needle width (NW), a baseline position (NP), a baseline reference position (Nps), and a sewing start position. (NE), Number of stitches (NC) The vibrating needle width (NW) is the width of the vibrating needle in each vibrating needle pattern. It is printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. For example, as shown in Figure 6 (A), i Needle width (NWs) refers to the width of the vibrating needle as 3 divisions. That is, nWs = nw / 3, and if there is a remainder in the division value, the left and right will be changed based on the center position of the width of the oscillation needle. Equal. INW Ma) '0, then NWs =] 6 more than 02. Therefore, the first stitch is 丨 7, the first stitch is 丨 .6, and the third stitch is h7 ′, which becomes the folded edge 1.6, 1.6, ι · 7. In addition, for example, the width of the vibrating needle in the case of a crescent button is the width of the pattern. The vibrating needle data is used in the vibrating needle according to the oblique 6 & vibrating needle. The vibrating needle material is required to be separated at the center. Borrow a model name. The wrong format holds the data of 24 pins and 12 pins, x 297 mm.) This paper ruler is used as a household standard (CNS) ^ 4 specification (21〇- 13 Α7)

V. Explanation of the invention (10) The calculation of the needle position is performed according to the formula using NDn as the needle transport data, NDp as the needle transport position, and NP as the baseline position. The baseline position (NP) is shown in Fig. 6 (B). The center of the vibrating needle mechanism of the initial sewing machine is taken as 0 ', the side of the initial sewing machine is taken as + (right side), and the opposite side is taken as-(left side). The vibration base point position of the vibrating needle is set within a range of 50 ~ 0 ~ + 50 within a range not exceeding the maximum vibrating needle width (WPx). η 3. The baseline reference position (NPS) refers to the baseline reference position shown in the case where the vibrating needle can be set to "center reference separation, right reference vibration, and left reference vibration" as shown in Figure 6. Separate ... Baseline position _ in the center. Right • Left Specify the vibration reference. For example, in the case of a point-tooth gap, when the baseline position (Np) = 0.00, the vibrating needle width (nw) = 'baseline reference positions (NPs) = left, the bayonet needle runs between 〇〇 and 3 〇 Vibrate the needle. The sewing start position (NS) is shown in Fig. 7 (b). Since the sewing start position next to the tangent is set to "Right. Left", the initial setting starts from left stitching. Also, among the crescent button hem and blind stitch, it is printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. However, when the right crescent button and right hem stitch are used, the left seam starts to change to the sewing start position. The number of stitches (NC) is the number of crescent button and blind stitches. When the crescent button is used, the standard is 24 stitches, and the three-day month is the same, and the 12 stitches are the same. The stitches are set between 3 and 25. . The initial setting of the crescent button [τ quasi-month. The average is 24 stitches' and the blind stitch is 4 stitches. In addition, the form of the secret coin that started to form the vibrating pin pattern was printed on this paper (i.e., i.e., s.e., home specifications (0. χ 297 mm)) 473573. Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs. 5. Description of the invention (11) Compression style), Long thread sewing, 2 material quilting, 3 point quilting, surrogate tooth sewing and conventional styles are all valid. Compressed money is from "starting to rewinding" as a pattern, and is performed in units of patterns. You can set the number within 釺. In addition, the compression transmission amount during compression is set by setting the transmission amount setting dial 7. For example, In the case of a 4-point crevice, as shown in Figure 7, 'Can be 6 patterns', because the i pattern is ice, the number of stitches is 18 stitches. In addition, as the selection of the stop (compression) setting, 'the following three methods' Among them, it is a method of stopping the seam with a pattern different from the style of the vibrating needle. The second is the conventional style setting of the seam. It is a narrow width of the vibrating needle within the width of the vibrating needle (nw). (Nw) The method of vibrating the needles in the same direction of the inner needle: Third, the conventional sewing pattern ^ to the pattern). 'The method of stopping the sewing with a different sewing pattern from the first vibrating needle pattern is related to Different from the vibrating needle pattern, since the stopper pattern (PC) is set at the beginning of the stopper and the end of the stopper, the width of the vibrating needle (cw), the number of compressions (cc), so ... the baseline position (NP), the baseline reference position (NPs) ), Sewing start position ⑽) Same as-. As shown in Figure 7, if 4 points are used to record the seam start, and the two-point zigzag stitch vibrating needle pattern and three-point zigzag end stop pattern are used as examples, the start-stop pattern is 4 points zigzag. The width of the vibrating needle is CW1. The number of times of compression becomes 3 times. The vibrating needle continues with this stop. The pattern is a 2-point zigzag stitch. In this case, the pattern of the vibrating needle after the end of the stop is not necessary. When the 4-point zigzag stitch is not determined, start the vibrating needle from the position where the end of the stop is close to the starting point of the vibrating needle.

V. Description of the invention (u) In the case where the start position of the sample is not the same as the end position of the stop pattern, a speed limit of 1 stitch is added after the end of the stop pattern. In addition, the end stop pattern is a 3-point zigzag stitch, the vibrating needle width is CW2, and the number of compressions is 4 times. At this end stop, the vibration stitch style is moved to the end stop style. However, the number of compressions plus the number of stitches is necessary as the number of compression stitches. The following describes the setting of the second stitching convention. The width of the vibrating needle is narrow within the vibrating needle width (NW). The number of stitches can be set. The vibrating needle is made in the same direction according to the movement of the needle within the width (nw). In the setting of this convention, at the beginning and end of the joint, the width of the start-compression-locking joint saw fPs), the number of start-compression-locking joint saws (CNs), and the end-compression-lock-jointing saw-vision (CPe) can be set to terminate the compression. The number of stuffing section saw pins (CNe) cannot be set when the number of stuffing section saw pins X the stuffing section saw pin > vibrating needle width. In the case of a two-point spur tooth joint, the cutting pin is cut by the vibrating pin width to form the moving vibrating pin width (m) of the normal vibrating pin and the vibrating pin. Moving vibrating pin width ⑼) = vibrating pin width (Nw) _ stuffing joint ore (C P *) X number of stuffing joint ore pins (c N *). In the case of 3㈣tooth seam, ‘by the width of the vibrating needle, the material is cut and the amount of vibrating needle is reduced’. When the needle vibrating needle width (NTs) is still small, it is used as the moving vibrating needle width ^ but 10 points of 3 tooth gaps. 'Removing and filling the vibrating needle volume from the vibrating needle width' is better than the 1-vibrating needle width (NWs). For larger occasions, you will!

Description of the invention (19 'Because the start and end of the seam are the same, so choose to start or end it)' According to the table in Figure 16 (A), automatically read the number of times of starting and stopping the seam, and stop the seam. -Number of people. When the two-point zigzag stitch, three-point zigzag stitch, and four-point zigzag stitch are respectively selected for the style of the vibrating needle of the stop stitch, they are respectively shown in Fig. 16 (C) (D). In Figure 16 when the two-point indentation stitch pattern is selected as the stop stitch, according to the table in Figure 16 (person), the number of times of starting and ending the stop stitch is 4 times. Dot-toothed oscillating needle pattern is repeated 4 times respectively. In addition, in Fig. 16 (c) (d), when the three-point staggered tooth gap and the four-point zigzag stitch pattern are selected as the respective seams, according to the table in Fig. 16 (A), The number of stitches is 3 times, so when repeating the 3 point zigzag stitch and the 4 point zigzag stitch, repeat the 3 times when starting and stopping the seam. Example of Fig. 16 (A). The normal vibrating pin pattern is 2 point zigzag. In the case of sewing, it is also possible to set such a table to each of the other majority of vibrating needle patterns, and to create the data for each vibrating needle pattern as shown in the respective i 6 (A) diagram. In addition, '' is not the number of times of seam stop, but it is also possible to make it memorize other parameters such as the number of seam stops.

Description of the invention (16) ΙΙΙΙΙΙΙΙ — · I Please read the notes on the back before filling out this page #This • By setting the number of steps and the data of the needle drop position in the number of steps, you can form each needle. The needle drop position data, that is, the vibrating needle pattern, can be used as a conventional pattern and stored in the memory 26. In addition, from step s6 丨 to S75 in Fig. 12, it is the process of setting the conventional pattern for stopping the seam. Figure 'Basically the same as the steps from Steps S41 to S55 in Figure 丨, and the point at which the seam stop switch 43 is operated in Step S61' and the point at which the paper lock LED 43a is turned on at 62 o'clock are only the same as in Figure 11 Steps S41 and S42 are different. In the case of inputting the data of the joint stop pattern above, when the joint stop pattern is "0", it is the same as the vibrating pin pattern. In the pattern, the amplitude of the vibrating needle also becomes the same, and the number of times of the seam stop (compression number) is performed along the flow of Fig. 10. When the style of the seam stop is "1" to "3", it is 2 points ~ Zigzag pattern at 4 o'clock, set the amplitude of the start or end of the stop and the number of times of the stop, according to the flow chart in Figure 10. In addition, 'When the style of the stop is "4"-line-Intellectual Property Bureau of the Ministry of Economic Affairs In the case of printing by employees' cooperatives, only the number of stitches is set because it is straight-line stitching. In addition, when the sewing pattern is "5" to "9", it is a conventional pattern, so the full needle branch position data is set.

For different occasions, such as Figure 7 Figure (c) or Fig. 8. [Setting of seam stop] In the present invention, the setting of seam stop is basically based on the selection of the style of the seam stop and the parameters of the seam stop (the number of seam stops and the number of seam stops) ). The setting of the parameter of the number of times of seam stop is This is performed according to FIG. 14.

This paper size applies the Chinese National Standard (CNS) A4 specification (21 × 2 2 mm) 473573 V. Description of the invention (π) Printed on the 14th figure by the Ministry of Economy and Commerce of Wisconsin, as shown in the aforementioned setting switch 41 and When the sewing stop switch 42 is turned ON, the set number of times of start of stoppage is highlighted on the vibrating needle display 48a (step SI10). . Secondly, in step S⑴, when the eight "+" "-" switch compensation or + "switch is operated, the number of times at which the sewing is started or terminated at the setting of the switch 46 or 47 can be set (step su2), Borrowing the number of stitches of the vibrating needle pattern at the time of seam-stopping N times the number of stitches M 'at the time of seam-stopping is used to calculate the number of stitches at the time of seam-stopping (step S113). For example, when the pattern of the vibrating needle at the start of the seam stop is a 4-point zigzag stitch, since the amplitude of the vibrating needle is "3" in this style, when the number of times of the seam stop is "3", the number of seam stops will change. = 9 ". It is also possible to set the vibrating needle pattern when sewing is stopped at the end of sewing. In this way, since the number of stitches at the time of stop stitching is determined by the product of the number of stitches at the time of stop stitching and the number of stitches of the vibrating needle pattern 'to determine the number of stitches at the time of stop stitching, the stop stitching must end at the end of the vibrating stitches and start In general sewing results, comparing with setting the number of stitches alone can prevent the occurrence of off-line. As described above, in step S26, the setting of the parameter for stopping the seam has been exemplified, and the number of times of the stopping seam is obtained as a parameter, but it can also be used instead of this setting as the parameter of the total number of seams when directly stopping the seam. But the seam counts! When the number of stitches of the vibrating needle width is not an integral multiple of ^ pure, the stop stitching is terminated on the way of the vibrating needle. When it moves to the normal vibrating needle pattern, the thread slipping occurs and the sewing product f deteriorates. Therefore, it is necessary to correct some problems. In Fig. 15, a seam parameter setting program processing using the total number of seams at the time of seam stop as a parameter will be described as an example of seam start.

The Ministry of Economic Affairs and Intellectual Property Bureau's Employee Cooperative Cooperative printed a status 48a to display the default value of the number of stitches at the beginning of the seam stop (step s20). In Fig. 15, since the number of stitches at the time when the seam is stopped is set, the number of stitches at the start of the seam stop is set with A "+" to "one" switches 46 in step spj. Continue in step S 1 and jade 2 'divide the number of stitches by the number of stitches N' of the vibration stop at the beginning of the stitching to obtain its quotient L and the remainder X. If it is judged in step S123 that the number X is 0, the set stitch number obtained in step S122 is used, for example, as the number of stitches at the start of sewing (step S124). On the other hand, when the remainder X appears This is rounded up to multiply (L + 1) with the number of stitches \, and the result is used as the number of stitches to stop the stitching (step S125). For example, if the pattern of start-stop stitches is used as a 4-point zigzag stitch, when the total number of stitches is set to "8", since 8/3 = 2.6, the number of rounding stops will be "3" and the total number of stitches will be " 9". As described above, the same procedure is performed when the seam stop is terminated. In this way, because the set number of stitches is corrected to the style of vibrating needle! The number of stitches of the vibrating needle width is an integral multiple of the number of stitches, so it will not move from the midway of the seam stop to the normal vibrating needle pattern, which can improve the sewing quality. In addition, in the present invention, instead of manually setting the number of times of the seam stop or the number of stitches at the time of the seam stop, it is automatically set in accordance with the setting of the style of the seam stop needle. To this end, a table as shown in Fig. 16 (A) is prepared. For example, when X is used for the normal vibrating needle pattern with two points of tooth gaps, the majority of the joint stopping patterns are determined for the vibrating needle type (two points of tooth gaps, three points of mineral tooth gaps, and four points of recorded tooth gaps) = each The stop stitch vibrating needle pattern memorizes the number of times of stop stitching at the beginning of the stop stitching and the end of the stop stitching '. This is stored as data in the memory 26 ^ After selecting the style of the vibrating needle at the time of stop stitching according to Fig. 9 (in Fig. 16 _ This paper is in accordance with the Standard for Financial and Family Care (CNS) A4 (2 $ X 297mm I Packing -------- Order --------- Line) Please read the notes on the back first (Fill in this page again) 22

Printed by the Consumer Affairs Bureau of the Ministry of Economic Affairs and the Intellectual Property Office. 5. Description of the invention (2) Step S82) Since the start of the seam stop is performed, the switch 63 is used to set the start seam stop pattern number. The code "Code" "G" ~ "9" is judged by steps S83 and S84. According to the respective pattern numbers, the memory% is read out to start the seam stop pattern. According to the read pattern, the needle 3 and the cloth are fed. The feeding function of the device is the same. It moves back and forth in the vertical direction to the feeding direction, and forms stitches with various patterns. At this time, when the stop stitch pattern is "0", the number of stitches N becomes the same as the vibrating stitch pattern (step S85), and when the stop stitch pattern is "dagger ~ Γ4", the number of stitches in the stop stitch pattern (step S86) ), Or when the sewing pattern is "5" to "9", the number of stitches of the pattern set by convention is used (step S87). Then, the speed limit is performed at step (step s88), and the process is shifted to the vibrating needle paper illustrated in step S100 to be sewn. After the vibrating needle pattern sewing is completed, the pedal is depressed backward (step S91), and when the end stop sewing switch 43 is judged to be ON (step S92), it moves to the end stop sewing pattern sewing shown in step state to S98. . The same pattern number is judged from "0" to "9", and steps S93 and S94 are performed, and the corresponding pattern number is read from the memory 26 to terminate the seam stop pattern. In this case, in the case of seam stop When the pattern is 0, the number of stitches M becomes the same as the vibrating stitch pattern (step S95). In the field where the termination pattern is r I "to" 4 ", the number of stitches of the stop stitch pattern (step S96), or only When the sewing pattern is "5" to Γ9 ", the number of stitches of the pattern set in the conventional manner (step. Step M is used to limit the speed (step S98). If the thread can be cut (step S99), then The thread trimming end operation is performed in step Si0. In addition, the number of seams of the number of seams of the seam stop pattern when the seam stop pattern is "1" to "4" (steps S86, S96) is in accordance with the fourth, ^ The picture comes from the paper rule of the paper WTcNS) A4 (210 x 297 ^) 24 Description of the invention (21) Settings or corrections. In addition, the settings are automatically set according to Figure 6 In the above implementation mode, the number of stitches is set as the sewing stop parameter at the start of sewing and the end of sewing, but even the number of needle drops can be set. [Effects of the invention] As explained above, in the present invention, the vibration needle reading of the vibrating needle pattern at the time of setting the seam is determined by the product of the number of times and the number of the vibrating needle width. Trace number. Therefore, when the number of stitches is set only, when the seam stop is terminated during the vibrating stitches, the sewing start position may be deviated. However, when the number of m stitches of the present invention is used, it must be stopped at the end of the vibrating stitches. Start of sewing end ㈣ so that the thread will not be taken off when the normal vibrating needle pattern and the vibrating needle pattern during sewing are moved, so the sewing quality can be improved. In addition, in the present invention, even when the number of stitches at the time of sewing is set, When stopping sewing with its stitches, stop stitching _ in the case where it was stopped in the middle of the needle vibrating stitches '' Because this is corrected to the number of vibration stitches at the end of the vibrating needle, so when the normal vibrating needle style and sewing The thread-stitching pattern does not slip off when moving, so the sewing quality can be improved. In addition, in the present invention, for a plurality of seam-stopping patterns, since the number of seam-stops or the number of seam-stopping traces that are most suitable for the sewing conditions can be set for each of the patterns of the seam-stopping patterns, even if the seam-stopping pattern is changed, It can also automatically set the most appropriate seam stop parameters to achieve high-quality seam stop.
