The present invention relates to a spiral twisted wire manufacturing apparatus mainly used as a material of the mesh for watch (MESH BAND) formed into a mesh.

In general, the wire material of the wristband mesh band is generally composed of a circular wire rod, and the circular wire rod is mainly used having a flat circular circumferential surface.

When the mesh band is made of such a flat circular wire, the appearance of the mesh band itself has simplicity, and thus there is a problem that the decorativeness is monotonous for a difficult manufacturing process of the mesh band. The method of forming the roller pattern by the pressing roller is considered, but the process of forming the forged pattern or the roller pattern on the surface of the mesh band is very difficult and this method is performed only when the mesh band is fully processed. Considering the problem that the formation process is difficult, there is a disadvantage that causes a lot of defective products when the process of forming a pattern on the mesh band of the complete processing state was not an effective method.

Therefore, in the related art, a method of forming a pattern on a mesh band by twisting a twisted wire rod twisted by twisting two round wire rods having a flat main surface has been considered, but the twisted wire rod composed of two strands has a valley (depth) between twist pitches. It is a defect that causes the design of the mesh band itself to be deteriorated due to the uneven and fluctuating relationship between the two strands of twisted wire when it is deep and each pitch is fluid. There was this.

The present invention is to provide a spiral twisted wire rod having a constant pitch by twisting the wire rod itself as a base material of the mesh band in one direction in consideration of the above-mentioned matters, and more specifically, the cross section is rectangular as shown in FIGS. 7a and b. Spiral twisted wire rod is provided by twisting twisting square member of square or square shape continuously, and the twisted twisted wire rod is twisted into the mesh band itself by weaving the spiral twisted wire rod into a net with a circular main wire having a flat main surface. Forming a pattern by the to be able to provide a mesh band having a better design than conventional forged pattern or roller pattern, when described in detail according to the accompanying drawings of the device of the present invention.

Below the base 1, a lower speed reducer 3 that decelerates the rotational speed of the motor 2 is addressed to the belt 4, and a belt 6 that is extended to the large pulley 5 of the lower speed reducer 3 is provided. ) Is located in the belt groove 8 'formed on the linkage shaft 8 of the upper reduction gear 7 provided on the upper surface of the base 1.

The linkage shaft 8 is elongated in front of the upper reducer 7 and forms a pivoting disc 9, and a bus bar having the inlet hole 10 'and the ejection hole 10 " The member dispensing opening 10 is detachably installed by the piece bolt 11 so that the bus bar member bobbin 12 having the square bus bar member P wound on the interlocking shaft 8 can be installed, and the rotation disc ( Two horizontal rods 13 and 13 'are symmetrically fitted to the edge of 9) and fixed with nuts 14 and 14', and a square bus bar P is formed at the tip of the horizontal rod 13 A guide roller 15 for guiding to the inlet hole 10 'of the member ejection opening 10 is mounted, and another crossbar 13 is attached with a finger piece 16 for holding the bus bar member bobbin 12 to the interlock shaft. (8) When the bus bar member bobbin 12 rotates more than necessary due to the acceleration of rotation due to the centrifugal force or the increase of the rotation force due to the loosening of the square bus bar member 9. The phases were to be controlled.

On the upper surface of the base (1) in front of the interlocking shaft (8), a support (17) is installed, and a large diameter and a small diameter are respectively formed with four rows of annular guide grooves (18) and three rows of annular guide grooves (19). A capstan device (20) consisting of a drive outlet (20a) and an interlocking outlet (20b) is installed, and the upper portion of the first annular guide groove (18 ') of the drive outlet (20a) of a large diameter is provided. The busbar member injection port 10 installed at the front end of the linkage shaft 8 is configured to be slightly eccentric with respect to the center (0) of the linkage shaft 8. At the time of rotation of the interlocking shaft 8, the drawing hole 10 ″ of the busbar member injection port 10 was configured to rotate around its center 0.

The drive gear 21 fixed to the output shaft 7 'of the upper reducer 7 interlocks with the smaller middle gear 23 of the middle gears 23 and 23' installed on the support plate body 22, and is a large middle gear. Reference numeral 23 'engages the large gear 24 for reduction.

The reduction gear 24 is engaged with a driven gear 25 which is affixed to the shaft of the drive outlet 20a of the capstan device 20, and two large and small chains are attached to the shaft of the driven gear 25. Gears 26 and 27 were installed together.

Next to the capstan device 20, a roller 29 ′ is attached to the tension adjusting device 29 in which the buffer spring 28 is installed to maintain the tension state of the twisted wire P ′ fed from the capstan device 20. And a movement guide ring 31 'for moving the twisted wire P' to the left and right between the tension adjusting device 29 and the rewinding bobbin 30 that winds the twisted wire P '. The left and right moving holes 31 are provided with a shaft 32 in which a plurality of movement guide grooves 32 'are connected to each other in an “X” shape, and the reduction gear chain 33 is fixed to one end of the shaft 32. ) Is connected to the chain with the chain (24).

Then, the rewinding bobbin 30 is installed on the shaft 35 provided at the upper end (right end in the drawing) of the base 1, one end of the shaft 35 is in an open state, and thus the compression spring 36 The rewinding bobbin 30 itself is the shaft (35) in accordance with the increase in the winding radius of the twisted wire (P ') is wound when winding the twisted wire (P') while holding the rewinding bobbin (30) in the configuration to insert a. The rotation speed is gradually reduced and the rotation speed is gradually decreased. The medium speed chain gear 37 of the shaft 35 speaks to the chain gear 26 as the chain 38 as the chain 38 and the compression spring 36. It was configured to replace the rewinding bobbin 30 on the shaft 35 by dismantling the cylinder 39 and the double nut 40 supporting the. On the other hand, the inner diameter of the inlet hole (10 ') of the above-described busbar member injection port 20 is formed relatively wider than the diameter of the square busbar member (P), on the contrary, the inner diameter of the draw hole (10 ") is a square busbar member (P). It is formed to have a size substantially equal to the diameter of the, and also the rewinding bobbin (31) to the left and right moving sphere (31) by the movement guide groove (32 ') connected to the axis (32) in which the left and right moving sphere (31) is installed. The twisted wire (P ') to the rewinding bobbin (30) can be neatly stacked and wound in a stack so that the rewinding bobbin (30) can be moved left and right as much as 30).

Referring to the process of manufacturing the twisted wire member (P ') twisted in a spiral state twisted square bus member (P) by the present invention configured as follows.

First, the busbar member bobbin 12 is dismantled at the front end of the interlocking shaft 8 to insert the busbar member bobbin 12 in which the square busbar member P is wound, and then the busbar member outlet 10 is fastened. The busbar member dispensing port 10 provided on the interlocking shaft 8 with a finger piece 16 of the lateral bar 13 ', and then the square bus member P wound around the busbar member bobbin 12. The lead end is hung on the guide roller 15 of the lateral bar 13, and the lead end is drawn out through the inlet hole 10 'of the busbar member outlet 10 to the outlet hole 10 " "∞" in the capstan device 20 by passing through the upper portion of the first annular guide groove (18 ') of 20a to the lower portion of the annular guide groove (19) formed in the interlocking drawer opening (20b) and withdrawn to the top After the speech, the square bus bar member P drawn out to the upper portion of the fourth annular guide groove 18 of the driving drawer 20a is passed through the roller 29 'of the tension adjusting device 29. (31) The moving guide ring 31 'is connected to the rewinding bobbin 30.

After installing the square bus bar member P as described above, when the motor 2 is operated, the linkage shaft 8 rotates at a moderately reduced rotational speed by the lower reducer 3, and also the upper reducer 7 The driven gear 25 fixed to the drive outlet 20a side of the capstan device 20 by the drive gear 21 fixed to the output shaft 7 'of the crankshaft rotates at a moderately reduced rotational speed. The drive drawer 20a of the device 20 is rotated while pulling the square bus member P wound around the bus bar member bobbin 12 installed on the linkage shaft 8, and thus the square bus member P Is recommended by the bus bar member bobbin 12 is guided to the guide roller 15 is fed through the bus bar member injection port 10, the drive drawer of the capstan device 20 to substantially pull the square bus bar member (P) Since the interlocking drawer 20b and the interlocking drawer 20b are woven in the shape of "∞" several times on the twisted wire (P '), the slip string Since the phase does not occur, the drawing speed of the square bus bar member (P) can be kept constant.

The rectangular busbar member P fed from the busbar member ejection port 10 by the rotational pulling force of the driving drawout port 20a of the capstan device 20 is drawn out with the inlet hole 10 'which is in communication with the "L" shape. The busbar member injection port 10 itself, which feeds the rectangular busbar member P, is in a tight state as closely contacted with the bent portion of the ball 10 "(see FIG. 4). Since the drawing hole 10 "itself is turning around the center (0) as shown in the example of FIG. 5, the drawing hole 10" is eventually driven to the front end of the drawing. Since the square bus bar member P is rotated with the part in close contact with the upper part of the first annular guide groove 18 ′ of 20 a, the square bus bar member P eventually leads to the inlet hole 10 ′ and the drawing hole 10. ") Is twisted between the upper part of the first annular guide groove (18 ') of the driving draw port (20a) from the bending portion between, where the drawing hole (10') Since itself is much larger than the diameter of the square bus bar member (P) can be expected smoothness in the inlet action through the guide roller 15, the hole (10 ") itself almost matches the diameter of the square bus bar member (P). It is configured to show the effect that can be expected smoothness of twisting phenomenon.

In addition, the interval of the twist pitch of the twisted wire (P ') twisted by the above action is proportional to the rotational speed of the linkage shaft (8) and the general rotational speed of the capstan device (20).

Therefore, when the rotational speed of the linkage shaft 8 is faster than the drawing speed of the capstan device 20, the twist pitch interval of the twisted wire P 'becomes narrow in a compact state, and conversely, the rotational speed of the linkage shaft 8 The slower the pitch pitch appears to be wider, in the present invention, the rotational speed of the linkage shaft (8) and the drawing speed of the capstan device 20 is appropriately adjusted to fit the twist pitch interval of the twisted wire (P ').

The winding radius gradually decreases as the rectangular busbar member P wound around the busbar member bobbin 12 is released, and accordingly, the unwinding rotation speed of the busbar member bobbin 12 is increased. When the member P is in a full state, the rotation speed of the busbar member bobbin 12 is lower than the rotation speed of the interlocking shaft 8 and is proportional to the drawing speed of the square bus bar member P while accompanied by an idle phenomenon. Regardless of the rotational speed of the interlocking shaft (8), the unwinding rotation is performed, and this phenomenon is because the unwinding rotational speed is controlled by the action of the holding force of the tungsten piece 16 attached to the horizontal bar (13 '). The square bus bar member P wound around the bus bar member bobbin 12 is constantly released according to the drawing speed of the capstan device 20.

Meanwhile, the annular guide groove 18 at the end (fourth) of the end of the driving outlet 20a is wound around the driving outlet 20a and the interlocking outlet 20b of the capstan device 20 as described above. Twist wire (P ') is wound on the rewinding bobbin 30 passing through the upper portion of the) is guided to the roller (29') of the tension adjusting device 29, wherein the tension adjusting device 29 is a rewinding bobbin ( Tension of the twisted wire P 'between the upper portion of the annular guide groove 18 at the end of the drive outlet 20a and the rewinding bobbin 30 according to the winding radius of the twisted wire P' wound on 30). By adjusting the rewinding bobbin 30 is to be able to accurately wound the twisted wire (P '), the movement guide ring (31') for guiding the tightening wire (P ') to the rewinding bobbin (30). Twisting wire while moving left and right in accordance with the left and right movement of the left and right movement port 31 to move left and right by the width of the rewinding bobbin 30 in the "X" shaped movement guide groove 32 'formed on the silver shaft 32 The rewinding bobbin 30 can be wound up by winding the twisted wire (P '), while the rewinding bobbin (30') induces the layer to be wound on the rewinding bobbin (30), and the rewinding bobbin (30) is the shaft (35). Since it is fitted to be idling on the surface and is subjected to the compressive elastic force of the compression spring 36, the twisting wire P 'causes the idling action on the rapidly rotating shaft 25 as the winding radius of the P' gradually increases. It can be wound without adding excessive tensile force to (P '), and thus the winding effect of the twisted wire (P') can be satisfied.

The present invention provides a twisted wire member having a twisted pitch like a rope to the bus bar member itself, which is a device of the mesh band, to produce a mesh band, and the embossed appearance of the mesh band by the twisted wire and the twisted pitch. ) Because the effect of the pattern can be variously applied, there is an advantage of simplifying the manufacturing process and lowering the manufacturing cost since it does not have to go through the pattern forming process of forming a conventional forging pattern or roller pattern, and the twisted wire manufactured by the present invention is twisted. Since the pitch is constant, it is possible to manufacture a mesh band in which the design according to the embossed pattern by the twisted wire is effectively expressed.
