Description of the invention (2) Printed by the Shelley Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economy The line Y is taken out from the shuttle 3 toward the shuttle axis, because it will not rotate when it is taken out. < Problems to be Solved by the Invention > The above-mentioned shuttle body of the vertical type also has the following problems. First, when the bobbin 4 is disconnected from the middle bobbin when the bobbin 4 is removed, the diameter of the bobbin 3a is smaller than the inner diameter of the bobbin. Therefore, the position of the bobbin 3 in the radial direction in the bobbin 4 is uncertain. 》 For this reason, the bobbin jaw 3b is detached from the edge of the bobbin 4, the lower thread bobbin 3 falls into the bobbin 4, and the bobbin jaw 3a and the inner surface of the bobbin 4 are engaged. The premises cannot be pulled out from shuttle 3. In addition, when hanging the lower thread Y to the thread adjusting spring 7, first, the lower thread Y must be pulled out through the hole 4a located at the center of the bobbin 4, and formed on the bobbin 5 so that the thread can pass through. 4 The upper surface passes through the upper and lower lines and is drawn into the cutout 4c, and the pin plate 5 penetrates the upper and lower lines into the slit 5a. For this reason, the upper thread can not form a seam when it is hung around the lower thread when bouncing around the middle of the shuttle, and on the other hand, while rotating the edge of the shuttle jaw 3a, the lower thread γ is pulled out, and the upper thread is pulled out and hung on the lower thread. The thread under the pull-in slit 4c and the thread under the pull-in slit 5a become unstable. In addition, since the thread Y under the take-in shuttle 3 is in a free state, it can be easily pulled out from the shuttle 3. For this reason, when the thread Y is hung under the thread adjustment spring 7, the lower thread Y becomes tension-free, and it becomes difficult to hang the thread adjustment spring 7. Furthermore, in the case of a horizontal shuttle body, the lower thread shuttle 3 is placed in a sealed state by being placed on the bottom of the inner shuttle body 1, and the oil trapped on the bottom of the inner shuttle body 1 collides with the lower thread and contaminates the lower thread. Furthermore, since the resistance of the lower thread Y around the edge of the shuttle jaw portion 3a is large, it is difficult to pull out the lower thread Y.

Description of the invention (3) The invention is in the shuttle body of the vertical stitch sewing machine, which makes it easy and reliable to hang the thread at the same time and form the connection. For the purpose. < Means for solving the problem > The bobbin of the sewing machine according to the present invention takes the lower thread from the axis direction of the shuttle shaft, the lower thread has jaws of different diameters, and rotates around the jaws of the lower diameter of the lower thread shuttle. At least one of the large-diameter jaw portion of the lower line and the edge portion of the bobbin forms a locking portion, which is configured to restrict movement in a direction of a mutual diameter when the bobbin of the lower line is mounted. In addition, the bobbin of the sewing machine of the present invention is taken out from the thread removal hole in the center of the upper part of the bobbin, and the lower line is rotated around the one jaw of the lower bobbin, and the above-mentioned thread removal holes are formed on the upper and peripheral sides of the bobbin. In order to pull in the cut through the thread, when the bobbin body is installed, it is formed by the middle bobbin body locking to form a range of 125 degrees in the direction of rotation " In addition, the bobbin of the sewing machine of the present invention, It is formed by the above-mentioned wire pull-in cutout, and in the exit portion of the wire-drawing hole, when the wire is pulled out, the lower wire is formed in a connection shape opposite to the direction around the jaw. In addition, the bobbin of the sewing machine of the present invention is formed by forming a take-out surface portion from the thread drawing-in slit and the exit portion of the thread drawing-out hole. In addition, the bobbin of the sewing machine of the present invention is composed of the aforementioned thread pull-in cutout, and the exit portion of the thread pull-out hole is provided so that the switch's elastic body can be freely plugged. In addition, the bobbin of the sewing machine of the present invention is taken out of the lower thread through a thread taking-out hole in the upper center of the bobbin, and the lower thread is rotated around one jaw of the lower thread.

This thread is drawn into the cutout 14f, and in the state where the bobbin 14 is placed in the middle bobbin body 12 ', it is formed by the non-rotating middle bobbin body 12 in the needle plate 19, and the bobbin body locks 12c and shuttles outward Position of the angular range (circle 3 (1)) of 125 degrees of the rotation direction of the body. Therefore, as shown in (3 (2) 圊), the angle (Θ1, Θ2) formed by moving the upper line of the upper surface of the bobbin 14 and the line drawn into the cutout 14f often forms 20 degrees or more, so It does not happen that the drop line is pulled into the incision. In addition, as indicated by the 4th (1) circle, the wire pull-in cutout 14f is at least in the exit portion of the wire pull-out hole 14e from the wire pull-out hole i4e and the edge direction of the lower thread rotation jaw 13a so that It is connected into a wire. Therefore, the lower thread Y is pulled out by the line pull-out hole 14e of the edge of the rotating jaw 13a, and when the lower thread γ reaches the exit portion of the line pull-out hole 14e toward the line pull-in cutout 14f, (in the 4th (1) th circle) (0-B), as shown in Figure 4 (2), because there is no edge on the inner side wall in the forward direction of the lower line advancing direction of the in-line cut-out 14f, the lower line Y passes smoothly without being entangled, and the lower line is also stable. status. On the other hand, it is different from the present invention. For example, as shown in Section 5 (1) (i), the size of the thread paper is applicable to the Chinese national standard (CNS > A4 size (210 X 297 mm)) (Please read the precautions on the back first) (Fill in this page again) I ^! II II I Order --- — — — — — Λ A7 B7 Printed by Shelley Consumer Cooperative of Intellectual Property Bureau of the Ministry of Economy In the exit portion of the hole 14e, if a non-wiring connection is provided, the inner edge 14g of the hole 14e is pulled out by the rotation line, and the lower line Y is drawn, as shown by the circle 5 (2). When the line of I4f is pulled out of the exit portion of the hole 14e (0-B in FIG. 5), the line is pulled forward in the forward direction of the lower line of the cutout 14f. Since the edge 14h of the inner wall is located on the object, the lower line Y is wrapped around the edge 14h. Therefore, the pull-out of the lower thread becomes unstable. Moreover, the wire pull-in cutout 14f in the exit portion of the wire pull-out hole 14e has a wiring shape, and it will not be disturbed even if it is broken in the middle. Although the wire is pulled in The cutout 14f is connected to the wire drawing hole 14e in a line shape, as shown in the 6th (1) circle, but The wire is drawn into the exit portion of the wire pull-out hole 14e of the cutout I4f to form a surface expansion portion (taken the face) 丨 4i. Pull out the side of the wire pull-out hole 14e to measure the line Y below the edge 14g, and it will not be at the exit. The entangled part can be easily passed through to form a stable pull-out line. As shown in Fig. 6 (2), the surface expansion part 14i can be formed only on the inner side. Similarly, the wire pull-in slit 14f can be pulled on-line. The outlet 14e is not connected with a wire shape. As shown in FIG. 6 (3), even if the outlet portion of the wire drawing hole 14e of the wire drawing incision I4f is fixedly plugged, one end of the elastic body 20 is free at the other end. It becomes stable to pull the lower thread. Moreover, even if there is an elastic body 20, the thread is suspended at the end of the lower thread. When the wire is pulled out of the hole 14e to the previous thread, the lower thread γ is pulled into the cutout 14f to enter the thread and pulled out. At the time of the hole 14e, the elastic body 20, as shown by the dotted line in FIG. 3 (3a), is pushed around the guided lower line γ, so the Y-side rotation line of the lower line is pulled out around the hole 14e, as shown by the arrow in the figure. Therefore, it is easy to be guided.

Description of the invention (8) Thread drawing hole 14e to the outer side of the shuttle The 14k line of the Tuning Meal〗 7 is set on the oblique section. In addition, when the thread is adjusted to the thread adjustment spring η, a window 14j for lower thread pressing is provided so that the lower thread Y 'can be pulled by fingers to the extent that it cannot move freely. As shown just now, when the thread is suspended, the lower thread Y is pulled out while rotating the thread pulling side jaw i3a of the lower thread hook 13. Since the lower thread Y is in a tension-free state, it is difficult to suspend the thread in this way. In the present invention, since the lower thread pressing window 14j is provided, the lower thread Y can be gently pressed with a finger above the jaw 13a, and the lower thread γ can be given a moderate tension and the lower thread Y can be pulled out of the hole by the thread. 14e passes through the groove 14k, and can be easily placed toward the wire adjusting spring 17. Although the lower thread Y is pushed by the window 14j, as shown by the circle 8 (1), a resistance made of an elastic material is provided at the window 14j, and the thread (the lower thread pushing device) is used to pull the thread out of the side part. The upper and lower lines Y of 13 a can achieve the same effect even if they are pressed to the extent that they cannot move freely in the same way as the aforementioned method of pushing with fingers. In addition, the supporting rigid body as shown in the 8th (2a) circle can also be used as a resistance. In addition, when the resistance γ is pushed by the resistance 21, as shown in FIG. 8 (2b), even if the line is pulled out of the side Pushing the side of the jaw 13a can also be 'as shown in Fig. 8 (2c) 囷, even if the upper side of the side jaw 13a is pulled out by the wire and pushes " 5J * 〇 On the latch plate 15, as shown in Fig. 9 (1) As shown in the figure, a wire pull-in slit 15c is provided to guide the lower thread Y to the wire pull-out hole 15b, which is the same as the wire pull-in slit 14f of the bobbin 14. This thread is pulled into the cutout 15c so that the lower thread Y does not fly out and extends non-radially from the thread pullout hole 15b.

Description of the invention (9) Which position is often pulled out to the line drawing hole 15b, and there is no acute angle in the direction of the line drawing. Moreover, the shape of the wire-cut incision 15c is limited to satisfy the above conditions, as shown in the 9th (2) or (4) circle, even if the curve, the straight line, the combination of the curve and the straight line, or the return is complicated. Lower the line, increase the force F (Figure 10 (2)) of the peripheral edge of the jaw 13a to be rotated, and take it out smoothly. As shown in Figures 10 (1) and (2), for the reel of the offline shuttle 13 The ratio of the diameter L1 of the jaw 13a of the lower thread shuttle 13 with the diameter L2, that is, the ratio of "[roll diameter L] / [diameter L]" is 1 / 2.5 or more, that is, 0.4 or more. As shown in Fig. 10 (3), if LWL1 is 0.4 or less, the force F of the edge of the small-diameter jaw 13a of the shuttle to be rotated becomes small, and the lower line cannot be smoothly taken out. In the case of a horizontal shuttle body, oil traces are easily trapped on the bottom of the middle shuttle body, and the oil is deposited on the lower shuttle and the lower thread and contaminated. Here, in the horizontal shuttle body, as shown in FIG. 11 (1), around the bottom portion 12d of the middle shuttle body 12, the jaw portion 13b of the lower shuttle 13 is provided with a loop-shaped segment portion 12e, so that the lower shuttle 13 13 g of the bottom does not touch the bottom 12 d of the middle shuttle body 12. In this case, even if some oil is retained at the bottom of the middle shuttle body, the retained oil will not only be deposited on the lower shuttle 13 but will not pollute the lower shuttle. In addition, as shown in section 11 (2) (i), the same effect can be obtained even if a ring-shaped protrusion 13h is provided at the bottom of the lower thread shuttle 13. In addition, regarding the lower thread shuttle jaw and the For the inventions other than the engagement of the edge of the bobbin, as shown in Figure 12, the diameters of the two jaws 13a and 13b are equal.

Attack Description of the invention (10) The thread bobbin 14 is also applicable. ≪ Effects of the invention > As described above, the bobbin of the sewing machine of the present invention will not be inferior to each other because the bobbin thread is in a state of being engaged when the bobbin is moved into the bobbin. It is customary to adjust the position of the bobbin thread while threading, and before it is installed in the middle shuttle, it can adjust the bobbin thread tension 'to improve the sewing ability. In addition,' Because the bobbin thread is pulled into the cutout 'from the setting state The shuttle body is locked, and the rotation direction of the shuttle body is set to a range of 125 degrees. The upper coil will not entangle the thread and pull it into the cut. In addition, the connection part of the thread pull-out hole that pulls the thread into the cut into the bobbin will be connected in a wire shape and pulled out toward the thread that is pulled into the cut. The exit portion of the hole is formed with a take-out portion and the exit portion is plugged and designed as an elastic body. Because the wire of the pin plate is drawn into the cut to make a special shape, the wire is smoothly and easily passed through and pulled out. In addition, when hanging the wire The lower thread is pushed and attached with moderate tension, so it is easy to hang the thread. Furthermore, in the horizontal shuttle, the jaw of the lower thread does not make it contact the bottom of the middle shuttle body, so even if there is left in the middle shuttle body Oil break, the oil break will not be attached to the lower thread bobbin, so there is no problem of lower thread contamination. ≪ Simple explanation of the round surface > The first 圊 is a miniature view of the sewing machine of the present invention, (1) is a plan view, (2) is a longitudinal section view.
