Description

200806841 IX. Description of the invention: [Technical field to which the invention pertains] The present invention relates to a button for a men's wear, a vest or a vest, a buckle for an inner pocket, a buckle for a pispocket, and the like. A sewing machine for sewing stitches used in various sewing products. More specifically, it relates to a sewing machine for sewing a stitch that is used to sew a button to a fabric by a needle that moves up and down in conjunction with a spindle of a slitting machine through a hole of a button. [Prior Art] This: sewing sewing machine with sewing machine's 曰 曰 公平 公平 7 7 辕 辕 = = = = = = = = = = = = = = = = = : : : : : : : : : : : : : : : : Folding the two folds into the middle of the fabric to keep the η holder's retaining the stitches of the needles through the holes: and the movable table, driving the button holders to move in the horizontal plane by the orthogonal Two-dimensional direction (front and rear, left and right, the button hole of the button holder and the pin of the needle plate 2: kind = the general sewing button sewing machine, tied to the button seam „1= The holder is driven by the movable body 2:: the sides are orthogonal to each other before and after the left and right direction, so as to keep the buckles on the fabric. The pin holes of the ten plates, thereby knowing the general sewing buckle With the sewing machine, the relative positional relationship between the button and the cloth when sewing the button is the same as that of the left and right hole pitches dl of the button 5G and as shown in Fig. 11, and the seams of the smashing 51 are damaged. From the d2 phase; the sewing thread core (10) forms a parallel state, so-called 5 200806841 parallel sewing. When such a parallel sewing is performed, if the object is sewn with a very soft shape, the left and right seams are caused, and the fabric portion between the stitching lines LN and RN is swelled, or the seam is formed to deteriorate the appearance. In particular, the button is attached. After sewing, as shown by A to N in Fig. 12, the left and right sewing buckles between the cloth „ Τχτ pin 51 and the button 5〇 are alternately inserted on both sides of the 、, and the buckle is twisted. Reinforced sewing thread LN, RN winding knot sewing (hand sewing

When the mechanical seam is ), it will be tightened by the buckle line BN, and as shown in Figure 13, from the left female

Right pull the fabric part between the left and right sewing threads LN and RN to create a large seam wrinkle. The problem of the quality of the sewing machine is reduced. In order to eliminate the improvement of the quality of the sewing product, such as the Japanese patent No. 271 chest number, the main purpose is: 帛, m The seam ^ A ^ _ moving α, is the driving button holder: it moves in the horizontal plane before and after the orthogonal to each other, the left = the ... the holder of the holder of the hole and the pin hole of the needle plate; The movable port ' # drives the fabric holder to move it in the horizontal plane: " rear, left and right direction; and can independently control the first and second = mouth movement pitch, when the button sewing, borrow The distance between the button and the left and right hole pitches is changed by the button, and the other distance I ST is moved to the left and right through the second movable table to be smaller than the pitch of the left and right holes of the button, to face |丄μ, The sewing thread is sewn into a V shape to eliminate the occurrence of seam wrinkles, and the button can be sewn with good appearance and good quality. I used the sewing machine for the sewing machine of the conventional sewing machine proposed by the Japanese Patent Publication No. 2711G24, and the conventional sewing machine for the sewing machine of the Japanese Patent Publication No. 7-49〇76, etc. The problem with the rush machine is that when the teacher sews on the soft fabric, the fabric of the left and right sewing thread LN, rn is raised, or the seam is sensitive, which causes the appearance to deteriorate. In particular, the sewing thread can be solved. There is a problem that the fabric has a large seam wrinkle and the seam product quality is lowered. On the contrary, in order to be able to be configured as described above, it is necessary to separately provide the second movable table (the left and right directions after the pure buckle holder is moved to be orthogonal to each other in the horizontal plane) and the second movable table (driving the cloth holder) Move it = the plane is orthogonal to each other before and after, the left and right direction), and it must also have the ability to make the 4th and 2nd movable tables so that the movements are different from each other. The overall structure of the sewing machine has become very large = further increase in weight and the cost of the sewing machine cannot be avoided: it rises. The vibration or noise when the X ’ two movable tables are driven to move is also poor from the working environment. [Summary of the Invention] The whole facts of the above-mentioned facts are "the purpose is to provide, and to make a cloth. Simple, compact, lightweight, and low-cost. Even if the object is soft, the seam will not be produced." Sewing machine for sewn fasteners with high-stitched products. In the sewing machine for the sewing machine of the present invention, the sewing machine for sewing the sewing machine of the present invention is a needle that is sewn with the sewing button and is reciprocated up and down through the respective holes of the button to move the button under the m2. 'There is a pin hole for the needle rf in the needle feeding, the cloth holder is inserted into the cloth folded into two folds, and the cloth is kept; the button holder is used to hold the button into the needle 7 200806841 j mouth base heat · and nightmare said, the movable table, the button is driven to hold the soil, the private movement in the horizontal plane before and after the orthogonal to each other, the left and right direction of the holder of the holder and the pin hole of the needle plate Consistent: Γ: 可 可 可 , 不 不 不 不 不 不 不 不 不 不 不 不 不 不 不 不 不 不 不 不 不 不 不 不 不 不 不 不 不 不 不 不 不 不 不 不 纽 不 纽 纽 纽 纽 纽 纽 纽 纽 纽 纽The fabric maintains the state of 盥', /, and left and right. ..."The holding device - the movement of the front and rear, according to / the invention of the above characteristics, can be used when the teacher sews, Lu right side = the holder is positioned to maintain the position to stop the fabric holder ^ right = move The state, and the movement of the buckle is moved to the left and right direction, and the right seam is set to "separate the left and right holes sequentially, so that the right seam line can be stitched into a ν shape, even if The soft fabric is a fabric holder that can be cut by the high-seam product at a predetermined position, and the fabric holder can be switched to the position of privacy protection, dislocation, and disengagement. Therefore, the conventional sewing machine can be used as the sewing machine (in order to achieve a V-empty π & sew), and the button holder and the stupid ", ..., ..., the knife drive can be driven. The two movable tables that move and the control functions for independently controlling the two movable tables of the green can make the overall structure very simple and not: the size, weight and cost of the machine body are small, and vibration or noise Also hangs J, and the working environment is good when the buttons are sewn. .
