Description of the Invention: [Technical Field] The present invention relates to a slitting device for a multi-needle-shaped slitting machine which is suitable for, for example, a cylindrical portion such as a neckline or a sewing loop of a stitching shirt. Cutting machine. In particular, it is about the ancient and the end of the free-form end of the wood with a suitable cylindrical body and the free-form end of the edge-shaped bed. Nakata has a multi-needle drop hole that is orthogonal to the direction of the cylinder axis and is disposed in the钍玟 罝 罝 忑 忑 洛 洛 洛 洛 洛 洛 洛 洛 洛 洛 洛 洛 洛 洛 洛 洛 洛 洛 洛 洛 洛 洛 洛 洛 洛 洛 洛 洛 洛 洛 洛 洛 洛 洛 洛 洛 洛 洛 洛 洛 洛 洛 洛 洛 洛 洛 洛= The needle thread and the line hook line between the needle plate and the wire hook after sewing are pulled sideways to the side of the tangent device. [Prior Art] Equipment: The basic configuration of the above-mentioned multi-needle-shaped sewing machine and the like is 备1, the j-end has a hook line portion, and the hook line portion is reciprocally driven to move along the horizontal plane to traverse the private formed by the needle plate 4 ^ The moving knife of the needle hole is hooked to the hook line by the shearing action of the movable knife when the movable knife moves in the one direction. On the other hand, the fixed blade and the broken wire portion of the needle thread which is moved to the side of the needle hole of the needle plate are elastically deviated from the front end portion of the movable blade. In the seam rushing machine with the tangential device composed of the above-mentioned constituent elements, the slashing action of the cutting edge of the moving knife and the fixed blade of the fixed knife is used to cut the delivery. ·+, h Μ Needle thread or needle thread and thread hook line, so the shearing force, that is, the sharpness of the sharpness, and the good sharpness of the sea, which does not change with time, is a very important technical matter. Too good to sell the known tangent device, used to achieve this important technology 6 200912077: For example, there is a spring knife pressing mechanism of the 曰本特开·75552, which is a spring that is placed on the back of the fixed knife to press the movable knife to the flat. An elastic pressing member such as a plate, and further, the profit is deteriorated over time, and the elastic force is adjusted to be an adjustable movable blade pressing mechanism member. The elastic blade is movable. However, the movable blade pressing mechanism configured as described above is used. It is known that the movable knife pressing mechanism of the slit of the tangential device (4) itself needs to be replaced by the elastic pressing force such as the pressing member, the mounting structure or the screw which is cracked on the back surface of the fixed knife. The number of parts. Because of the installation of the clamping plate of the pressing mechanism, it is extremely difficult to make the narrow space of these numerous objects. In addition, due to the large number of parts, the parts are different. From the pre-"elastic pressure of the pair of movable knives: the difference, one fruit, it is difficult to ensure that the expected good sound is sharp and even when adjusting the elastic pressing force: the deterioration of time. The invention is based on the above facts, and the purpose is to provide a reduction = profit:: ease of assembly and rationalization The tangential device for maintaining the good sharpness is a splicing device for solving the problem, and the splicing device has a splicing device and is provided with a splicing device. The hook line 200912077 is a movable knife that reciprocally drives and moves along the horizontal plane to traverse the needle drop hole formed by the needle plate, and is hooked to the fishing knife by the shearing action of the movable knife when the movable knife is driven to move in the forward direction The thread is transferred to the side of the needle hole of the needle plate, and the needle thread and/or the thread of the thread hook are cut. The stencil is cut, and the end of the thread to be cut is at the front end of the movable knife. The inter-partial elastic clamping wire plate is characterized in that: in the reciprocating driving movement path of the movable blade, a position closer to the back surface of the needle plate than the cutting edge of the fixed blade is formed to have the same thickness as the movable blade or Roughly above and below the width, and at least The cutting between the knives is slidably contacted with the front and back sides of the movable knives and the ends of the movable knives are pressed against the slits of the guide knuckles. Further, in the present invention, which is proposed for the same purpose as described above, the slitting device with the tangential device of the sixth aspect of the invention is fixed at the free end of the tubular bed. a needle plate having a hard pin hole which is orthogonal to the direction of the cylinder axis and a feeding groove for being disposed in the direction of the tube axis before and after the needle hole hole, and the cylindrical bed in the lower part of the needle plate is provided in the cylindrical bed a hook for reciprocating oscillating motion in a direction intersecting with the feeding direction, and comprising: a front end side f: a fishing shape having a hook line portion on an inner circumference of the curved front end portion, and the front end fishing line 2 is on the axis side of the needle plate For the center of the reciprocating swing along the line hook, the horizontal plane between the road l and the back surface of the β-shaped needle plate reciprocally drives and oscillates to traverse the movable knife of the two-digit drop hole, and borrows when the movable knife moves in the forward direction By the shearing action of the = move 77, the hook line is caught and transferred to the needle plate, and the fixed knife that cuts the needle thread and the line hook line on the side of the mountain hole, and the cut mountain that is to be cut The elastic blade of the movable knife is elastically held by the end plate; the special reciprocating driving swing road of the movable cutter In the case of the fixed knife, the 200912077 cutting edge is close to the back of the needle plate, and the gentleman is ^^ α ^ ^ ^ or has a width of 4 or more equal to the width of the movable knife, and at least >乂 滑动 精 精 精 精 精 精 精 精 精 精 精 精 精 精 精 精 精 精 精 精 精 精 精 精 精 精 精 精 精 精 精 精 精 精 精 精 精 精 精 精 精 精 精 精 精 精 精 精A slitting machine having a tangential device according to the first and sixth aspects of the present invention having the above-described features can achieve the following effects. That is, the reciprocating driving movement (oscillation) path of the movable blade is formed in comparison. The cutting edge of the fixed knife is close to the position of the back surface of the needle plate, that is, the slit having a step above the cutting edge of the fixed knife is restricted to be fixed, so the cutting is performed by the fixed knife When the cutting line is actuated, the front end portion of the movable knife can be elastically displaced by the cutting edge of the fixed knife, and the front end portion of the movable knife is elastically connected to the fixed knife with a force corresponding to the elastic restoring force. Cut the edge of the knife. For the sake of the money, the slit can be used to move the knife to The effect of the elastic pressing of the fixed knife side is not required. As in the conventional cutting device, the movable blade pressing mechanism is adjusted by elastic pressing members such as a spring plate, an Annon member attached to the back surface of the fixed blade, and an elastic pressing force such as a long hole or a screw. It is necessary to use parts and the like as the number of parts. It is only necessary to fix the belt-shaped presser plate to, for example, the #面面 of the needle plate and the portion protruding from the back of the needle plate to the lower part. In order to maintain the sharpness of the movable knife pressing force b, the pressing blade that exerts the movable blade pressing function does not have to be concentrated on the clamping plate mounting portion on the back of the needle plate, and can be disposed slightly away from the clamping plate mounting position. 'Therefore, the installation of the pressure plate and the wire loss plate will not complicate the installation work due to the staggered space. -曰_ 'The movable knife is in and out for catching the needle thread and/or the wire hook line, due to 200912077 Since the movable blade is released from the slit and the elastic force of the cutting edge of the fixed blade is released, the front end of the movable blade is moved to the front end of the movable blade by using an elastic pressing member such as a spring plate than the conventional movable blade pressing mechanism. The state of the elastic side of the fixed knife side, the movable knife system focuses on the main function of the hook line, and does not have to pay attention to the solid knife! · Health press function. Therefore, the pressing force of the hook portion of the movable blade at the front end of the movable blade can be reduced, and the wear caused by the sliding of the movable blade and the fixed blade can be reduced, and the good fortune can be maintained for a long time. Therefore, not only can the number of parts be reduced, the cost can be reduced, the assembly can be easily simplified and rationalized, but also the error of the elastic pressing force of the movable blade generated by the accumulation of manufacturing errors and assembly errors of the parts can be minimized, so that it is easy to ensure good expectations. Sharpness. Further, even if the pressing force adjustment mechanism is not specifically provided to form a slit having a constant size such as a vertical width, it is possible to suppress the sharpness from falling over time, and to ensure good sharpness even when used for a long period of time. The tangential device of the first and sixth aspects of the patent application scope of the present invention, the slit in the slitting machine can be formed on the back side of the needle-saving plate and sent in the second and seventh items of the patent application scope. The front and rear positions of the cloth are arranged between the two protruding portions of the needles that are fixed from the needles to the lower portion of the strip, or as described in Items 4 and 9 of the patent application form. The state of the needle board itself. Wherein, if the latter is formed in the I state of the needle plate itself, the number of parts can be further reduced without the need for a belt-shaped pressure plate. However, it is necessary to form a slit for the thin needle plate and insert and insert the movable knife from it. High precision machining technology and complicated assembly. On the other hand, if it is formed between the needle plate H γ surface and the π-shaped press blade, the number of parts and the number of through-slit parts are slightly increased, but the processing and assembly surface is advantageous. Further, in the sewing machine having the tangential device of the second and seventh aspects of the patent application of the present invention, as described in the third and eighth aspects of the patent application, the belt-shaped presser blade is integrally connected. It is preferable that the movable blade that has moved out of the slit is returned to the slit before the cutting line is cut by the cutting action of the fixed blade. At this time, the slit can be minimized so that the movable/sliding contact range is applied to the negative section of the driving mechanism of the movable blade, and the movable blade can be surely returned to the slit to pinch when the wire is cut. A sharp cut-off function. The franchise plays the scope of the patent application of the present invention - "Please request the fifth item of the patent range:; * two = set two... adjust the elastic clip P piece of the wire clamping end of the wire clamping plate, regardless of the type of wire and the number of wires, It can be used in the state of the end of the wire.

Therefore, when the movable blade 15 is reversely swung to the retracted position shown by the solid line in Figs. 6 and 7, and the needle thread NT and the thread hook line LT are cut by the shearing action with the fixed blade 16, 13 200912077 The upper and lower opposing faces of the slit 38 (the back surface 5b of the needle plate 5 and the upper surface of the strip-shaped press blade are in contact with each other) are in sliding contact with the front and back surfaces of the movable blade 15, and the movable blade. Specifically, as shown in FIG. 8, the hook line fishing line portion 15a and the needle thread hook portion 15b elastically displace the cutting edge of the fixed blade 16 upward. The hooking portions 15a and 15b are elastically pressed and guided by the cutting edge 16a of the fixed blade 16 with a force corresponding to the elastic restoring force. Further, in the substantially central portion of the longitudinal direction of the belt-shaped presser blade 36, the movable blade which is separated from the slit 38 and swings forward in the forward direction to the position shown by the broken line in Figs. 15 is urged to guide back to the return guide 39 in the slit 38 when swinging in the reverse direction from the entry and exit position. The fixed knives 16 of the tangential device 18 are reversely swung from the entry and exit position shown by the broken line in Fig. 6 and Fig. 7 to the retracted position shown by the solid line in Fig. 6 and -7. In other words, when the arrow e is swung in the direction of d, the hook between the movable blade 15 pressed against the fixed blade 16 by the action of the slit 38 is cut and the hook is hooked at the front end thereof. , ... a line of fishing line L that is transferred to the side of the needle drop hole 13

The tubular portion of the sewn product is fed to the feeding piece a, and is, for example, covered. At the end of the predetermined sewing, the movable blade 15 of the tangential line 18 is slidably contacted with the sliding contact of the upper and lower faces of the slit 38, that is, the needle plate 5 = face 5b and the upper surface of the γ-shaped presser plate 36. The guiding action, the fixed knife 16 clamping plate 17 "clamping guiding action swings along a certain horizontal plane", the hook-shaped fishing line portions 15a, I5b at the front end thereof traverse the three needle holes / 3 of the needle plate 5 and are After the drive is swung in the forward direction to the entry and exit position shown by the broken line in FIGS. 6 and 7, the drive is reversely swung from the position to the solid line of FIG. 6 and FIG. When the reverse drive swings, the two needle threads NT passing through the needle drop hole 13 in the up and down direction are hooked on the hook line portion i5b, and are locked to the hook hook 6 (the hook line hook LT is hooked on the hook line portion 丨5a) It is transferred to the side of the needle drop hole i 3 and the feed tooth groove 14. When the movable blade 15 is driven to swing in the reverse direction, the movable blade 15 is in sliding contact with the front and back facing the fixed blade 16 The cutting edge i6a is slightly displaced upward, and the slit 38 having a step is swung in the slit 38 in a state in which the lower facing surface of the slit 38 is the upper surface 5b of the needle plate 5 and the upper surface of the strip-shaped pressing blade 36. The hook line hook line hook portion 5a and the needle thread hook line portion 15b of the front end portion are elastically displaced upward as shown in Fig. 8 to the step of the cutting edge 16a of the fixed blade 16. With the force corresponding to the elastic restoring force, 16 200912077 the hook portion "... is elastically pressed against the cutting edge of the fixed knife i6, and is hooked to the hook portions (5), (10) and transferred. The line fishing line and the needle thread NT are cut off at the end of each line by the strong edge of the movable blade 15 and the cutting edge of the receiving blade 16 Elastically clamped between the front end portion of the movable blade 15 and the wire end grip portion 17a of the center plate ί 7. As described above, the slit Μ which is formed on the back surface 5b side of the needle plate 5 functions as the movable blade 15 Since the effect of the elastic pressing on the side of the fixed blade 16 is eliminated, an elastic pressing member such as a spring plate of the movable blade pressing mechanism provided in the conventional thread cutting device, a mounting member attached to the back surface of the fixed blade, and elasticity such as a long hole or a screw are not required. According to the number of parts for pressing the adjustment parts, it is only necessary to mount the boring plate 36 to the protruding portion 5C, 5C outside the back surface of the needle plate 5, and it is extremely simple to add X and (4) very few parts can be used to improve sharpness. The movable knife is pressed by the dust function. In addition, the fixed position of the pressing blade 36 which forms the slit 38 which exerts the movable blade is not concentrated on the mounting portion of the clamping plate 17 of the back side of the needle board $ It can be installed at a position slightly away from the clamping plate Η mounting position. Therefore, the mounting of the pressing blade 36 and the clamping plate 17 is not interlaced in a narrow space, and the assembly work can be facilitated and rationalized. By reducing the number of component parts The number can reduce the cost, and the manufacturing error and assembly error can be accumulated to cause the elastic pressing error of the movable blade to be extremely low, and since the front end hook portion nsb of the movable blade is elastically pressed only when the tangential action is applied The cutting edge 16a' of the fixed blade 16 can reduce the abrasion caused by the sliding of the elastic pressing of the two blades 15, 16 'can maintain a good sharpness as expected for a long period of time 17 200912077 and 'even if the pressing force is not specifically set The adjusting mechanism fixes only the slit 38 of a constant size such as the upper and lower widths, suppresses the sharpness from falling over time, and ensures good sharpness even when used for a long time. Further, the slit 38 may be formed to penetrate the needle plate 5 itself. However, when the back surface 5b of the needle plate 5 and the belt-shaped pressure plate 36 are formed as described in the above embodiment, the high-processing technique is not required to form a slit through the thin needle plate 5. The number of components is slightly There is an increase but it is advantageous in both processing and assembly. - Even in the above-described embodiment, the adjusting piece 27 is swung in the direction of the arrow f_g with the head of the mounting screw structure #32a as one of the fulcrums, and the elastic clip of the end portion of the threaded plate 17_ can be adjusted. With this, regardless of the type of the wire or the number of the wires, the wire end portion can be elastically held between the movable blade 15 and the tension plate 17 at any time. Further, although the above-described tenth embodiment is applied in detail to a tangent device which is implemented in a three-cylinder slit, it is also applicable to a double-cylinder slitting machine, four needle-shaped slits (four), and a single-cylinder cylinder. In addition, when it is applied to a tangent line in a machine 33 of various forms such as a flat interlocking seam, in the above embodiment, it is described that the bending of the movable blade 15 is formed in the inner periphery of the end portion. The line hook line (four) line 胄 ... and the needle line fishing line ^ 1 5b, but the needle thread and the line hook line can also be hooked on the single hook hook line portion. / In addition, the movable knife reciprocating drive mechanism is described in the above embodiment曰: Department:: The simplification, cost reduction, and ease of installation work are most: *Besides '', various types of drive mechanisms can be used. 200912077 [Simplified illustration] t 1 :'·, the present invention The sewing machine with the tangential device is suitable for the overall three-dimensional view of the seam cutting machine when the three-slot sewing machine is used. 4 Figure.
