Description of the invention (1) ~ "Detailed description of the invention" Back to the top) Please fill in this page again. The present invention relates to a bobbin guide device of a sewing machine, which is attached to the face of the needle plate. A hook protrusion is loosely fitted on the stop of the shuttle system, and the shuttle body is held on a horizontal rotary hook for a non-percentage sewing machine, so that the shuttle body is forced to turn in the direction of rotation with the hook. In the opposite direction, an upper loop is formed at the stop of the shuttle to pass through the gap. "Known technology" The horizontal rotary hook for the sewing machine is composed of a hook body and a hook, but when the hook is rotated, the hook body does not rotate with the rotation of the hook. A pair of hook members (shuttle system stops) are loosely inserted into the hook hole exit of a shuttle body. Usually, although the hook protrusion of the shuttle body is continuously hooked to one of the stopping members by the friction with the rotation of the hook, the upper loop that rotates around the shuttle body cannot pass through the hook protrusion and the stopping member. In this way, the upper thread ring is subject to great tension and causes an action that prevents the formation of a slit. In addition, in order to make the upper loop pass easily, the shuttle body guide rod is forcibly brought closer to form a passing gap of the upper loop. " •• '' '^ 十-" ^:-^-": ^ 丁 ， 消 于 合 竹 ^-印 ^! ^

"Problems to be Solved by the Invention" When the upper loop passes through the shuttle body, it is necessary for Ruibao to pass the upper loop through the hook protrusion 27a and the stopper member 29. The crimping state of the front end portion 20a of the body guide and the crimping portion 27b of the shuttle body is maintained for a certain period of time), and in the next process, the upper thread is passed between the crimping portion 27b of the shuttle body and the front end portion 20a of the shuttle rod Ensure a required interval (quickly leave from the shuttle body crimping portion 27b of the shuttle body front end portion 20a). However, the conventional shuttle body guide has an end portion 20a, which is a linear trajectory as shown in FIG. 5, so if the upper loop is to be passed through the hook protrusion 27a and the stopper member 29, The time required for this is to lengthen the stroke of the front end portion 20a of the shuttle body guide bar during crimping, so that the swing amount of the shuttle body 27 is increased, and the tension of the lower thread becomes unstable. In addition, in order to ensure that the upper thread passes through the space between the shuttle body crimping portion 27b and the front end portion 20a of the shuttle body guide, it is necessary to move the shuttle body guide 20 at a high speed. On the other hand, when the front end portion 20a of the shuttle body guide and the crimping portion 27b of the shuttle body collide with each other, the speed of the front end portion 2 of the shuttle body guide is also at a high speed, so a very large collision sound is generated. Moreover, after the shuttle body crimping portion 27b collides with the shuttle body front end portion 20a, the shuttle body 27 is still rotated at a high speed, so the shuttle body 27 is rotated at a very fast speed, so that the hook protrusion 27a (first read the back and Precautions 4¾¾ • This page) Pack., Ιτ. ^ This paper is suitable for national standards and national standards.

Description of the invention (3) — ~ '—-Collision with the stop member 30, and a wolf loud collision sound is generated. This month is when the upper thread passes through the shuttle system stop under the needle plate, the shuttle body 1 guide rod functions to reduce the shaking amount of the recorded cylinder body, and at the same time, the shuttle system stop and hook are attached to the shuttle body. The stopper's embarrassment & φ + 丨 97 hangs on the collision of the crying part to reduce the impact and the impact sound as its purpose. "A device to solve the problem" This month is the hook protrusion of the shuttle body when the upper end of the shuttle body guide rod acts on the shuttle body piecing portion so that the upper loop passes the shuttle system stopper under the needle plate. The shuttle body guide rod device of the sewing machine which forms the upper loop passing clearance between the stopper of the previous shuttle system and the stopper of the previous system has a driving device formed by the front end of the shuttle body guide-the upper loop passes through the space and simultaneously makes the shuttle The boat guide acts so that the front end portion of the shuttle body guide is separated from the shuttle body crimping portion approximately along the direction in which the shuttle body crimping portion is formed. The driving device of the present invention is one whose speed is slowed down when the front end portion of the shuttle body guide bar is brought into contact with the shuttle body crimping portion. The driving device of the present invention causes the front end portion of the shuttle body guide rod to perform an elliptical motion in the same direction as the rotation direction of the hook. The driving device of the present invention is such that the major axis of the elliptical motion is oriented along a surface forming the shuttle body crimping portion. On the major axis of the elliptical movement track, the outer portion of the shuttle body guide bar la from the position of the shuttle body 10 is 10 to 5000 / 0D, and the hook tip 9a and the needle fall. The angle when the points coincide is regarded as 0. The rotation angle of the shuttle body is 250 ~ 290. At this time, the front end la of the shuttle body guide rod is located at the farthest position from the shuttle body 10 on the elliptical motion locus.

Description of the invention (5) The guide link shaft is set to allow the eccentricity of the machine to be adjusted. "Embodiment of the invention" Figs. 1 to 6 show the embodiment of the shuttle body guide device of the sewing machine according to the present invention. As shown in Fig. 1 and Fig. 2, the bobbin guide is synchronized with the lifting movement of the sewing needle, and a hook 9 fixed to the bobbin shaft 4 and a rotatable fitting to the hook are used. The shuttle body 1 of 9 is a horizontal shuttle for this sewing machine. And the hook protrusion protruding from the outer periphery of the shuttle body 10 is £ 1, and is loosened between a pair of stopper members 12, 13 provided below the needle plate 11. The shuttle body guide rod 1 'of the present invention is fixed to one end of the shuttle body guide arm 2, and the other end of the shuttle body guide arm 2 encloses an eccentric cam 5 that supports an eccentric cam fixed to the shuttle shaft 4. In addition, on the middle portion of the shuttle body guide arm 2, a pivot pin 7 is used to make the swing end of the shuttle body guide link 3 rotatably supported by the shuttle body guide link shaft 6 rotatably supported. Connected. The shuttle body guide bar 1 is bent toward the shuttle body 10 side ^ By the eccentric cam that rotates with the rotation of the shuttle body shaft 4: 5, when the shuttle body guide link 3 is restricted and the shuttle body guide arm 2 is shaken, The front end portion 1a of the shuttle body guide bar crimped to the shuttle body crimping portion 10b becomes a movement mark depicting an ellipse as shown in FIG. That is, when the hook body 10 is rotated in a direction opposite to the rotation direction of the hook, and when the hook protrusion 10 a is separated from the stopper member 12, the front end h of the hook body guide bar is opposite to the rotation direction of the hook 9. , Becomes the state of the elliptical motion track rotating clockwise. Pass in the note of the back first and then fill the page. 1T Let's take the position of the outer end of the shuttle body crimping part] 0b as the zero point. And the line passing through the shuttle body crimping part 10b is regarded as the γ axis, and its orthogonal line is regarded as the χ axis. T) 436549 A7 —______ B7 5. Description of the invention (6), the elliptical motion trajectory is longer in the Y-axis direction, that is, becomes longer along the direction of the shuttle body crimping portion 10b. Looking at the speed of the tip end la of the shuttle body guide from this elliptical motion trajectory, it can be seen that the current system decelerates to a slow state when it hits the shuttle body crimping portion i0b. Therefore, the impact sound of the front end portion of the shuttle body guide bar a and the shuttle body crimping portion 1 Ob is almost eliminated. In addition, as shown in FIG. 3, the speed component when the front end la of the bobbin guide bar is pressed against the bobbin crimping portion 10b is larger in the Y direction than in the X direction, so it is continuously ensured that the upper thread passes through. Since the time between the hook protrusion 10a and the stopper member 12 can be suppressed to a small amount, the bobbin j0 can be kept at a small amount, so that the lower thread tension can be stabilized and a good sewing mouth can be formed. In addition, the front end la of the bobbin guide bar is crimped to the bobbin crimping portion 10b, and the moving speed in the X-axis direction is accelerated, but before it leaves the bobbin crimping portion 10b, it is decelerated again to Slow speed, so the shuttle body becomes a slowly rotating state, and can also avoid the impact of the hook protrusion 10a and the stopper member 13 due to the strong rotation of the shuttle body 10 will not produce a large impact sound . It can be understood from FIG. 5 that the shuttle body guide bar 丨 of the present invention makes the shuttle body 10 turn red and causes the front end portion la of the shuttle body guide bar after the upper loop has passed to move away from the shuttle body ^ 〇. Along the positive direction of the y-axis of the shuttle body crimping section 丨 0b. This situation means that the returning direction of the shuttle body 10 after rotation is opposite to the direction in which the front end of the shuttle body guide rod 1a is away from the shuttle body], so that the return of the shuttle body 10 becomes easy ( By the way, the learner is in the same direction). Therefore, more than half of the elliptical motion trajectory can be taken into consideration to move the hook projection 10a away from the stopper member 12. In other words, the positive part of the y-axis (the upper part of the x-axis) of the elliptical motion trajectory is the length of the elliptical motion track, which can make the front end of the shuttle body guide la from the paper Standard Tongchuan 屮 valve g family standard （((: NS> Λ4 size (210X297 male foot) 436549 A7 _______ B7 V. Description of the invention (7) The outer part of the shuttle body 10 position is made 10% to 50%. Based on this As shown in Fig. 3, "the time required for the upper loop to pass through the hook protrusion 10a of the shuttle body 10 and the stopper wall 12 (shuttle mechanism stop) is sufficient, and as shown in Fig. 4 It can ensure that the upper thread passes a sufficient time between the front end portion k of the shuttle body lever and the prism crimping portion 10b. Regarding this, the conventional example shown in FIG. The returning direction is the same as the direction in which the front end portion 20a of the shuttle body guide leaves from the shuttle body 27. Therefore, 'when the stroke of the shuttle body guide rod is long, if the distance acting on the pressure contact portion of the shuttle body is reduced,], ", The action time will be shorter, and the passing time of the upper loop is not enough." In addition, when the stroke of the shuttle body guide is short, The front end portion of the body guide bar 20a acts on the shuttle body crimping portion 27b for a long time, but the distance from the shuttle body roofing portion 27b cannot be sufficiently ensured. In addition, the shuttle body guide system of the present invention is shown in FIG. When the angle of the hook tip% coincides with the needle drop point 1 la is regarded as 0. When the shuttle body rotation angle is within the range of 250-290 °, 'is set so that the upper loop can pass through the front end of the shuttle body guide la When the angle is within this range, the distance between the front end portion la of the shuttle body guide rod and the Y-axis direction of the shuttle body 10 must be set to at least the distance through which the upper thread can pass. Moreover, when the angle range is noted above, By setting the tip of the shuttle body guide 1 a on the elliptical trajectory to the position farthest from the shuttle body (point p on FIG. 5) 1, the distance from point p to the shuttle body can be reached. The distance is minimized, so the elliptical motion profile depicted by the front end la of the shuttle body guide rod can be minimized, and the surrounding area can be reduced in size. To meet the above conditions, the shuttle body guide arm 2 is connected. The connecting line between the center of the connecting portion of the shuttle body guide link 3 and the front end portion of the shuttle body guide bar, and this paper Dutong ;!] in the storehouse standard 肀 (rRS) Λ4 specification (210 · κ 297 public dream) m-II _ -___ II — 士 _ --- n I-! &Quot;, __ I____ 1. {诮 先Read.

Description of the invention (8) Make the angle where the connecting line intersects with the center line of the shuttle body guide arm 2 to 40 ~ 70 " Yes, i. Referring to FIG. 8 later, in the second embodiment of the shuttle body guide in which the front end portion of the shuttle body guide traces a circular motion, only the differences from the previous embodiment will be described. The shuttle body guide rod Γ is fixed on a rotating shaft 15, and the rotating shaft 15 is a rotator by a driving source (not shown). As the driving source, for example, a bobbin shaft similar to that of the aforementioned embodiment can be made. In this case, the same number of rotations is transmitted from the bobbin shaft to the rotation shaft 15 by gears or the like. The shuttle rod Γ makes the front end of the bobbin rod draw a circular motion trajectory and acts on the bobbin body 10. The state of the shuttle body guide bar front end portion 1'a and the shuttle body pressure contact portion 10b is slightly larger than the shuttle body guide bar of the aforementioned form, but because the shuttle body guide bar front end portion Γ a The direction of departure after hitting the shuttle body crimping part 1 is the same direction as the previous embodiment along the direction of the shuttle body crimping part 10b. Therefore, it is possible to ensure that a wide upper thread loop passes through the shuttle system stop (equivalent to the aforementioned implementation) Formally, the time between the hook protrusion 10a of the shuttle body 10 and the stopper member), and at the same time can ensure that the upper thread passes a sufficient time between the front end of the shuttle body guide ra and the shuttle body crimping section 丨 〇b. . A third embodiment of the shuttle body guide device of the sewing machine according to the present invention will be described with reference to Figs. 9 to 13. The shuttle body guide rod device of the third embodiment is attached to the shuttle body guide k1 of the shuttle body guide arm 2 by a latch 7 to enable a shuttle body guide that is swingably supported by the shuttle body guide link lever 6.

Description of the invention (9) A plurality of shuttle body guide link shafts 6 are provided, and a plurality of pairs of shuttle body guide links on the shuttle body guide link 3 are also provided. Connecting holes 3a, 3b of the shaft 6. The k body is generally a person who selects the timing of passing the loop which is most suitable for the type of cloth to be sewn and the type of thread to be used. Because the phase of the eccentric cam 5 of the respective shuttle body is slightly different, if the components are connected in the same state, 'the movement trajectory of the front end la of the shuttle body guide will also change', but not absolutely The best. Here, select any combination of the above-mentioned plural [shuttle body guide link shafts 6, 6], [connection holes 3a, 3b], [connection holes 2a, 2b] (g) The example shown in (g) follows 8). The ideal movement track of the front end of the shuttle body guide bar [a] on the shuttle body can be obtained. Those shown in Figs. 2 to 4 are examples of combinations thereof. Referring to Fig. 13, a description will be given of a long hole 3c as a plurality of connecting holes for connecting the shuttle body guide link 3. This is because the fixed position of the shuttle body guide link shaft 6 can be set at any position of the long hole 3C, and therefore, more detailed processing can be performed compared with the case where plural connection holes 3a and 3b are provided. In this case, in the state where the bobbin guide link shaft 6 penetrates the nut 15 and the cylindrical step screw 16 arranged above and below the long hole 3c of the bobbin guide link 3, it is fixed to the installation by the fixing screw 14. On the base material b, the fixing of the shuttle body guide company 3 pairs of the shuttle body guide link shaft 6 is fixed as follows, that is, the shuttle body guide link 3 faces the shuttle body guide link shaft 6 along the length The hole 3c is moved, and the nut 15 is secured to the cylindrical stepped screw 16 at an arbitrary position. Referring to Fig. 14 ', a fourth embodiment of the shuttle body guide device of the sewing machine according to the present invention will be described.

The shuttle body guide is characterized in that an eccentric shaft portion 6a is provided on the shuttle body guide link shaft 6, and the shuttle body guide link; when the 3 is fixed on the shuttle body guide link shaft 6, a plurality of 3a is selected. The point where either or 3b is fixed is the same as in the first embodiment. Therefore, in addition to the advantages of selecting any one of the plural 3a and 3b for fixing, the shuttle body guide rod has the following advantages, that is, it guides the shuttle body penetrating through any one of 3a and 3b. When the eccentric shaft portion 6a of the link shaft 6 is fixed to the mounting base B by the fixing screw 14, the head of the link shaft 6 is guided by a rotary shuttle body such as a screwdriver, and the shuttle body guide link 3 can be arbitrarily changed. The relative position of the face to the eccentric shaft portion 6a. This is expected to be the same as that of the first embodiment in which the surface of the fixed link 3 guided by the shuttle body through the long hole 3c shown in FIG. 5 is arbitrarily set to the position of the shuttle body guide link shaft 6. Effect. That is, when the ideal motion trajectory of the front end U of the shuttle body guide is obtained, it can be handled very carefully. Since the present invention is configured as described above, the following effects can be obtained. That is, because the shuttle body crimping portion of the shuttle body guide when the shuttle body leg hook rotates in the opposite direction of rotation has a small amount of action and a slow speed, it is the same as those with a conventional fixed shuttle guide. The sound produced during the operation is very small. In addition, since the amount of action on the shuttle body crimping portion of the shuttle body guide bar is small, the swing amount of the shuttle body is reduced and the lower thread tension is stabilized. As a result, a good seam π can be formed. In addition, it is possible to lengthen and get the upper ring through the front end of the bobbin body guide and the shuttle to stop the material. In addition, the number of transfers is the same as that of the learner, and the manufacturing cost is the same.
