[Known technology] It is well known that buttonhole overlock sewing machines are used to form buttonholes on the object to be sewn, and to perform overlocking at the same time. The buttonhole overlock sewing machine conveys the sewing object held by the presser foot in a certain direction by the cloth feeding mechanism, and tangles through the wire of the needle and winds the bottom line of the bobbin in the bobbin case device. The stitches forming the hole overlock. The buttonhole is formed by sewing the stitches on the front and back of the hole, and lowering the cloth cutter on the upper side toward the cloth cutter receiver on the lower side to cut the object to be sewn. [Problems to be Solved by the Invention] In addition, when placing the cloth on the needle plate of the sewing machine, if there is sufficient space between the cloth presser foot and the needle plate that have been raised to the highest position, the I The cloth is inserted on the needle plate. However, in the conventional buttonhole overlock sewing machine, the highest position of the presser foot is fixed. Therefore, there is no problem with most thick cloths. However, for example, if the material to be sewn is a very thick cloth such as a baby seat, the highest raised position of the cloth presser foot is too low to be pressed. Pull out the cloth smoothly under the cloth feet and put it on the needle plate, which results in a lack of operability when the cloth is fixed. In addition, the cloth presser foot is placed between the highest position and the lowest position of the cloth presser foot position, and the cloth is made close to the cloth while the gap is close to the cloth. Move your feet for easy alignment. The center position of the right C cloth foot is fixed. In the case of thick cloth, it is pressed due to the cloth pressure) A4 size (210X297 male f -----

The setting value of the cloth pressing degree (the middle position of the cloth pressing foot) when stepping on the pedal is an important feature. In this way, for the buttonhole overseaming pattern for sewing thick fabrics, by setting the highest raised position of the pressing cloth, a sufficient space can be left between the cloth and the pressing feet, and the cloth can be slid on the needle plate. Remove it in order. In addition, for thick cloths, by setting a higher intermediate position of the cloth presser foot, the cloth presser foot can be spaced and approached to the cloth, and the cloth can be smoothly moved relative to the cloth presser foot, and the cloth can be easily adjusted. Bit. In the foregoing, the so-called reverse needle lifter height is that the needle located at the stop position above the top dead point and slightly lowered protrudes from the lower side of the clamp foot and damages the height of the clamp foot of the sewing material under the clamp foot. To avoid this, the needle must be positioned at the height of the work clamp foot which is higher than the upper stop position. The value of the height of the reverse needle lifter is unique to the sewing machine. The sewing machine of this embodiment can be changed and set within the aforementioned range. The reverse rotation of the needle at the upper stop position is performed by reversely rotating the sewing machine motor by a certain amount. Unlike the normal rotation of the sewing machine, which is performed by the normal rotation of the sewing machine motor, the needle can be raised without forming a stitch.

In this embodiment, the button presser foot control as described above is performed during the buttonhole overlock. I The flowchart of the buttonhole overlock processing process in the eleventh embodiment. The flow chart in Fig. 11 starts when the power of the sewing machine i is turned on. This flow includes the operation panel setting processing in step 51 and the pedal pressing processing in steps S4, 6, and 9. In addition, the cloth press height moving process is performed in step S18 (Fig. 12) of the operation panel setting process. Explanations of these processes are started. The operation panel setting processing is performed by the operator through the operation panel 100 to set the pattern number and sewing data of the buttonhole when sewing buttonholes, and it is performed according to the flow shown in FIG. Normally, the pattern number selection by the pattern number key 104a on the operation panel setting position starts. Next, input the data No. 'to be input-input its data value' and repeat the operation until the desired full data No. is input. In FIG. 12, first, in step su, it is determined whether the operator has pressed the key of the operation panel ,, and if not, the processing is ended as it is. Next, at step S12, the pattern number is selected by the operator by pressing the key on the operation panel 100, that is, the pattern number key 104a, and the patterns NO · 1, 2 shown in the data table in FIG. , 3, 4 · · · Select the ideal hole overlock pattern (pattern key processing).

In step S27, when it has been determined that the data No. 18 has been selected, as in the step, the setting value of the f cloth height (middle position) when the pedal is stepped on one step is entered and set in the RAM 113. In step S24, it is determined whether the height of the cloth presser is not lower than the height of the reverse presser. If it has been determined that the height is not lower, after performing the reverse kicker in step ⑵, the pulse wave motor of the presser foot is driven in step S26. , Make the cloth presser foot move (down) to the height of the cloth presser when the pedal is pressed. In general, the height of the presser foot of the 1st step of the pedal is lower than the height of the reverse stitch. Therefore, the process proceeds from step S24 to step S26 without going through step S25. Based on the above, the actual fabric is used before sewing in the setting stage of the operation panel, and the movement of the presser foot based on the setting data to the highest and middle positions can be confirmed. With this, after the setting of the data is completed, the height of the presser foot can be surely controlled in the pedal pressing process performed in the flow chart in Fig. U. The pedal pressing process is the height control of the presser foot of the sewing industry after the operation panel setting process is completed, and it includes the control of the operation of the foot pedal 84 performed by the operator. And according to the process shown in Figure 16. As shown in FIG. 16, in step S31, the position of the pedal 84 is detected by the pedal sensors a and B, and it is determined whether the pedal is in the neutral position.

Description of the invention The needle is positioned at a certain position above the top dead center. Then, in step S35, the pulse wave motor 127 of the presser foot is moved (raised) to the presser height (the highest raised position) when the presser foot is moved to the neutral position of the pedal. In the above description, the needle that is reversed and located at the upper needle position is the height of the cloth pressing when the pair has risen to the neutral position of the pedal, that is, the height of the cloth pressing foot at the highest raising position, which does not protrude downward. Thereafter, when the cloth is inserted into the needle plate, the cloth will not be damaged by the needle. In this embodiment, each buttonhole overlock pattern can set the highest position of the presser foot, so even for thick cloth This is also possible. At step S33, it has been determined that the height of the work clamp is lower than the height of the work clamp of the reverse lifter (NO). Since it is not necessary to perform the reverse lift of the lifter at step S34, the process moves from step S33 to step S35, and at step S35 The pulse wave motor of the presser foot is driven to move the presser foot to the neutral position of the pedal (the highest raised position). In step S31, when it is determined that the pedal is not in the neutral position (because the operator has stepped on it), in step S36, it is determined whether the pedal is in the pedal position, and if it is in the pedal position in step 1, then in step S37, Record the pressing height (the setting value of the data NO.18) of the i section of the pedal and set it in the RAM 113. Then, in step S33, determine whether the pressing height is not lower than the reverse pressing needle pressing height. If it is judged that it is not low, after performing the reverse stitch raising process in step S34, the pulse wave motor of the cloth presser foot is driven in step S35, so that the cloth presser foot is moved to the cloth presser height (middle position) when the pedal is stepped on one step. Normally, the pressing height of the pedal during one-step chatting is lower than the reverse needle lift height, so the process proceeds from step S33 to step S36 without step S34. This paper size applies to China National Standard (CNS) A4 specifications (2) 〇297297 public love 567262 A7 I-- ~ __ V. Description of the invention (21) is already located at the height of the cloth when the pedal is stepped on, that is, The presser foot in the middle position is in a state where the cloth is vacated and close to each other. Therefore, if the needle plate has been inserted into the cloth, the cloth can be smoothly moved relative to the presser foot and the cloth can be aligned. In this embodiment, since the middle position of the presser foot can be set for each buttonhole over seam, this is possible even with thick cloth. Also at step S36, when it has been determined that the pedal is not in the i-step pedal position, that is, when the pedal is in the 2-step or 3-step pedal position, in step S38, the lowermost position of the presser (presser position) is recorded and Set to RAMU3. Because the lowered position of the cloth presser is lower than the height of the reverse cloth presser, the step S33 is performed without going through step S34 to step S35. In step S35, the pulse wave motor of the cloth presser foot is driven to make the cloth presser foot Move (lower) to the most lowered position (pressing position). Next, the flow of buttonhole overlock in Figure 11 will be described. In Figure ii, the operation panel setting processing shown in Figure 12 is performed in step Sb, and in step S2, it is determined whether the operation panel 1 is pressed. If the preparation key 101a of 〇〇 has been pressed, the process proceeds to step S3. If not, the process returns to step S1. The final step of the setting operation of the s Hai operation panel is as described above. When data N0.17 and 18 are selected, the reverse stitching process is performed according to the needs, and the work clamp foot is moved and located in the work clamp of data No. 17, 18. Height, confirm its movement to the highest and middle positions based on the setting data. In step S3, the process of calculating the needle drop position is performed based on the setting data set on the operation panel 100. Then, in step S4, the previous steps related to the operation of the operator putting and fixing the cloth on the needle plate of the sewing machine , Perform the pedal pressing process shown in Figure 16. The pedal processing is as described above. It is determined that the national standard of the paper (CNS> A4 specification (21GX297 Gongcheng)) applies to the paper size. &Quot; '--24- · :: .............. ... ^…: (Please read the notes on the back before filling in this page) • Order 丨: Line · 567262 A7 ------; ______ V. Description of the Invention (22) (Please read the notes on the back first Please fill out this page again} The board is located in the neutral position, 1-step pedal position, 2-step pedal, or 3-step pedal position. If Qian Qian wants, reverse the needle up process, and make the presser foot toward the corresponding pedal. The position of the cloth pressing height is moved. When the cloth is started to be placed and fixed on the throat plate, the pedal is in the neutral position and the cloth pressing foot is in the most raised position. Next, in step s5, it is determined whether the preparation key is pressed. lOla, if the ready key 10a is pressed again, it returns to step S1 again to make the setting made by the operation panel 100 possible. At step S5, the right side has to press the ready key i0ia again, and at step sg, while the operator is pressing the pedal (Figure 16), the fabric of the sewing product is fixed on the needle plate. The operator has not stepped on the pedal, When the pedal is in the neutral position, the presser foot is at the highest position. At this time, the highest position of the presser foot is raised in accordance with the thickness of the sewing fabric, because each buttonhole overlock pattern can set one presser foot The most raised position ', so that even a thick cloth can be sufficiently spaced from the presser foot, and the thick cloth can be smoothly inserted on the throat plate. It can also be turned upwards to raise the needle. The needle in the position does not protrude downwards from the presser foot that has already been raised to the highest position, even if it is a thick cloth, it will not be damaged by the needle. When the operator steps on the pedal for 1 step, the presser foot is in the highest position and the highest position. The middle position between the lowered position. At this time, the middle position of the presser foot is raised in accordance with the thickness of the sewing fabric. Because each buttonhole overlock pattern can set a middle position of the presser foot, even if it is thick The cloth can also make the cloth presser foot close to the cloth, and move the cloth relative to the cloth presser foot and easily align the cloth. After the cloth is aligned, the operator can step on the pedal (Step 2) Paragraphs) to make table paper dimensions applicable Chinese National Standard (QyJS) A4 specification (2) 0 > < 297 mm) -25- 567262 A7 j______B7 5. Description of the invention (M) The cloth foot is lowered to the lowest position, and it is embedded in the cloth press lever The spring imparts potential energy and presses the cloth with the cloth presser foot. Then, when the worker presses the pedal more (3 steps), the switch of the sewing machine is turned on (ON). Due to this, the pressure is determined in step S7. The cloth feet are in the lowermost position, and the start switch has been turned on (3 steps), and the process proceeds to step S8, where sewing processing including overlock, cut buttonholes, thread trimming, etc. is performed. The opening of the feet also takes place automatically. The pedal system returned to a neutral position by chatting and letting go. When the sewing process in step S8 is completed, after the pedal pressing process is performed in step S9, the process returns to step S5, and the operation is repeated until the buttonhole oversealing of all the sewing objects is completed. In the step pressing process of step S5, after the operator finishes sewing the first buttonhole, when the pedal is depressed for one step, the work clamp foot is stopped at the middle position. Therefore, the sewing of the second buttonhole can make the The cloth presser foot is maintained in a state where the cloth can be easily aligned. The same applies to the sewing of the third or lower buttonhole. Since the buttonhole overlock sewing machine according to the embodiment of the present invention has the above structure, the following effects can be exhibited. (1) Because each buttonhole overlock pattern can set a maximum raised position of the presser foot, the highest raised position of the higher presser foot is set by matching the thickness of the sewing cloth, even if the sewing cloth is thicker. It can also leave a sufficient space between the cloth presser foot and the cloth can be smoothly taken out and put on the needle plate, which can improve the operability when the cloth is fixed. (2) Because each buttonhole overlock pattern can set a middle position of the presser foot, the middle position can be set by matching the thickness of the cloth being sewn.

Thereby, even with thick cloth, it can move smoothly with respect to the cloth presser foot, and it can be easily aligned, and the operability during cloth fixing is further improved. (3) When raising the presser foot to the highest position, if the highest position that has been set is higher than the height of the needle tip that has passed the top dead point and is at the stop position above the needle, 'reverse the sewing machine motor so that The needle at the upper stop position reverses the needle up position to not exceed the top dead center position. Therefore, by raising the presser foot to the highest position, the needle can not protrude toward the lower side of the presser foot, and it does not damage the insertion of the presser foot. Cloth under the feet. (4) When setting the height of the work clamp to reverse the needle up, the needle up can be reversed when it is the same as and lower than the raised position of the work clamp. (5) When the highest position and intermediate position of the presser foot have been set, drive the presser motor before the cloth is fixed. By moving the presser foot to its set height position, you can confirm that the direction of the presser foot has been set. Since the height position is moved, the height control of the presser foot after the data setting is completed can be surely performed. (6) The operator can operate the sewing machine by operating the foot pedal to move the presser foot to its highest position, etc., thereby improving operability. [Second Embodiment] In the present embodiment, the cloth pressing height is moved and the pedal pressing process is performed.
