The present invention relates to a welding processing apparatus for continuously welding both ends of a wristband mesh band formed by chaining a left spiral coil material and a right spiral coil material as a pin material.

More specifically, the pinned spiral material is penetrated by the pin material so as to be sandwiched between the mutual pitch of the left spiral coil material wound in the left direction and the right spiral coil material rolled in the right direction. The right and right spiral coil materials are chained together, and the left and right spiral coil materials chained together with a pin material by primary compression processing using a press or a pressing roller are in the bound state as shown in FIG. Both ends of the left and right spiral coil materials are in close contact with the pin material without scattering, but the left and right spiral coil materials, which are chain-bound with the pin material, are welded to both ends of the primary crimping process. For each end of a left, right helical coil material and a right helical coil material in close proximity to one end of one pin material When the mesh band is finished in the next process, the mesh band itself has flexibility and welded at both ends in a rounded state. Therefore, welding processing is provided to provide a mesh band that never shows a tear in clothing sleeves. The purpose is to provide a device.

The conventional mesh band adopts a method of grinding and polishing both ends, and the mesh band manufactured by such a processing method must have sharp edges of each shape formed at both ends thereof, and are bound to the left and right spiral coil materials and plates. As the end of the material is displayed as it is, it is not possible to eliminate the occurrence of voids, and the sharp uneven surface is formed inside the surface of the void itself. The sharp uneven surface causes the clothing sleeve to open, and not only the feeling of wearing is soft, but also the bad defects such as torn off the sleeve of the clothes are caused.

Therefore, in order to solve the above-mentioned drawbacks, the present invention has been filed in Korean Utility Model Application No. 87-16883 due to this cause as a welding processing apparatus for welding only necessary parts without grinding and polishing both ends of the mesh band. This also maintains the beautiful appearance of both ends of the mesh band and welds both ends in a rounded state, which completely eliminates the phenomenon of tearing off the sleeves when worn, but has a chain-bound left and right spiral shape. Since the welding of each pin material closely adjacent to each cut surface of the coil material is performed by individual welding method without welding continuously, it takes a lot of welding processing time, which has the disadvantage of lowering the productivity of the mesh band.

Therefore, the present invention is to solve the drawbacks of the Utility Model Registration Application No. 87-16883 mesh band welding processing apparatus, which is the first cause of the above-mentioned cause, and to improve it, as a welding device on the left and right reciprocating setting device It is possible to process a large amount of mesh bands in a short time by providing a process means for continuously welding both end sections of the mesh band in one instant, and thus greatly contributing to productivity improvement.

When described in detail the effect of the present invention configured as described above.

The binding configuration of the general mesh band (B) is, as shown in FIG. 5 by firstly chaining the left spiral coil material (B ₂ ) and the right spiral coil material (B ₃ ) with the pin material (B ₃ ) while alternately arranging them in parallel. As a press or crimping roller, the primary crimping process is performed, and the left and right spiral coil materials (B ₁ ) and (B ₂ ) are compressed in the upper and lower parts as shown in FIG. 6, and thus the pin material (B ₃ ) cannot freely escape. At the same time, both ends of the pin material (B ₃ ) are bound together at both ends of the left and right spiral coil materials (B ₁ ), (B ₂ ).

As a general means as described above, the processing means for welding the both ends in the mesh band (B) of the unfinished state, which is primarily processed, is a subject to be solved by the present invention, specifically, the upper plate of the setting device (5) By turning the two eccentric spheres 9 and 9 'installed on the (5 ") to the lever in the same state as the phantom line as shown in FIG. 2, the eccentric sphere 9 and 9' is eccentrically below Since the eccentric pins 10 and 10 'are moved upward, the operating rods 8 and 8' vertically connected thereto raise the setting brackets 7 and 7 ', and at this time, the setting brackets ( 7) Compression springs 13 and 13 'of the guide rods 11 and 11', which are installed between the 7 'and the top plate 5 " The lower plate (5 ') has a wide space for convenient insertion of the mesh band (B), and as shown in Figure 3, the adjustment plate 27 is installed on the rear side of the setting bracket (7), (7'), The throttle 27 Since it is installed as the bolt 28 screwed to the lower plate 5 'through the long hole 27', the adjusting plate 27 itself is moved forward and rearward through the long hole 27 'with the bolt 28 slightly loosened. The control plate 27 can be adjusted appropriately, before and after, and fixed to the width of the mesh band B to be welded by being able to move and adjust.

Insert the mesh band (B) on the lower plate (5 ') so that one end of the mesh band (B) is in close contact with the front of the control plate 27 adjusted to the width of the mesh band (B) as described above, and then the eccentric sphere (9) If the lever of 9 'is turned back to the left side as shown in the solid line of Fig. 2, the eccentric pins 10 and 10' move downward, so the operating rods 8 and 8 'are lowered. At this time, the compression springs 13 and 13 'of the guide rods 11 and 11', which were compressed between the setting brackets 7 and 7 'and the upper plate 5 " Mesh seated on lower plate 5 'while lowering with setting brackets 7 and 7' screwed to actuating rods 8 and 8 'with a force to elastically press down 7'. The band (B) is elastically pressed to be fixed. At this time, the front welding end, which is the protruding portion of the mesh band (B) fixed by the setting brackets (7) (7 '), is protruded in a state suitable for welding. Will be.

Next, the horizontal bar 19 is integrally and horizontally directed to the upper and lower height adjustment adjusting means 19, which is fitted to the vertical fixing rod 18 'of the magnetic device 18 magnetically attached to the upper surface of the base 1. The tip of the welding needle bar 25 protruding from the tip 23 'of the welding machine 23 is brought close to the welding end of the mesh band B by the rotation operation of'), and then screwed on both sides on the adjusting device 19. When the bolts (symbol abbreviation) are tightly tightened, the adjusting mechanism 19 is firmly fixed to the vertical fixing bar 18 ', so the horizontal bar 19', which is connected to it, is also kept fixed, and the horizontal bar 19 ' When the knob 21 'of the lower fixing tool 21 installed at the end is slightly released, the height of the vertical adjusting rod 20 fitted vertically to the lower fixing tool 21 can be adjusted. After adjusting appropriately and tightening the knob 21 ', the vertical adjustment bar 20 is adjusted to an arbitrary height. After fixing, slightly loosen the knob 22 'of the upper fixture 22, and then operating the welding needle bar of the welder 23 by controlling the upper and lower movements of the upper fixture 22 up and down on the upper side of the vertical adjustment rod 20. 25) After adjusting the welding end of the tip and the mesh band (B) to the exact position where the short can be shortened, tighten the knob 22 'to fix the upper fixture 22, which is attached to the upper fixture 22 The pair of attachment holes 24 are inclined to fix the lower mounting portion 23 'of the welder 23, so that the welder 23 itself is fixed in a slightly inclined upward direction with respect to the mesh band B. In addition, as shown in FIG. 3 and FIG. 4 during the adjustment of the upper fixture 22 fixed to the upper part of the vertical adjustment rod 20 as described above, the welder 23 itself is welded to the mesh band B. Adjusting and fixing to have an inclination angle in the opposite direction to the moving direction (right direction) Is recommended.

As the above-described operation of the position of the welding machine 23, the left side and the right side operation of the switching valve between the switching valve 17 'of the air supply valve 17 installed on the upper surface of the base 1, the air is air The piston rod 16 'is brought in and out by the suction and discharge action introduced into the front end side or the rear end side of the cylinder 16, so that the moving port 4 attached to the front end of the piston rod 16' ) And the setting device 5 formed integrally therewith to reciprocate the rail rods 3 and 3 'on the left and right sides.

Therefore, the lower part of the setting device 5 has a moving hole 4 and another moving hole 4 'connected to the tip of the piston rod 16', so that the setting device 5 has a rail rod 3, ( 3 ') is settled in a stable state, so the left and right reciprocating motion is also stable.

And, in the operation of the air cylinder 16, the left and right reciprocating speed of the piston rod 16 'is a pin material for the welding needle bar 25 of the welder 23 to weld the welding end of the mesh band (B) The ends of the left and right spiral coil materials B ₁ and B ₂ , which are in close contact with the ends of (B ₃ ), may be adjusted to have a predetermined traveling speed at which the ends of the coils may be welded as a short row.

In addition, welding of the welding needle bar 25 and the mesh band B when the setting device 5 moves forward (operates from left to right in the drawing) with the piston rod 16 'in the air cylinder 16 is released. However, circuits were configured so that the positive and negative electrodes could be simultaneously applied and shorted, and the circuit configuration of the sparks on both sides of which the installation width was adjusted on the air cylinder 16 according to the length of the mesh band (B). The adjustment sensor devices S ₁ and S ₂ are configured to automatically adjust the power-on time. The operating distance of the piston rod 16 is constant, whereas the length of the mesh band B depends on the type. It is because they are different.

Therefore, the operator accurately adjusts and fixes the installation widths of the spark adjustment sensor devices S ₁ and S ₂ according to the length of the mesh band B to be welded, and then the power switch of the welding machine 23 (not shown). After operating in the ON state, the air cylinder 16 is operated to start the welding process of the mesh band B.

At this time, as described above, the welding machine 23 itself is inclined upwardly and adjusted to an inclined state (see FIG. 3) slightly inclined in the opposite direction with respect to the traveling direction of the mesh band B in which the welding operation starts. When the setting device 5 is moved from left to right in the drawing while the welding machine 23 is fixed, the left spiral coil material B ₁ or the right spiral coil material B ₂ is first shorted and melted. The fin material B ₃ is to be shorted.

That is, since the left and right spiral coil materials (B ₁ ) and (B ₂ ) are thicker than the pin material (B ₃ ), the left and right spiral coil materials (B ₁ ) and (B ₂ ) are shortened first, and thus the diameter is thin. This is to prevent the phenomenon of excessive melting of the pin material (B ₃ ) to expect a good welding state.

Therefore, as described above, the power switch is turned ON while the mesh band B is set in the setting device 5, and then the reciprocating operation between the switching valves 17 'of the air supply valve 17 to the right. When the air is supplied to the inside of the front side of the air cylinder 16, the piston rod 16 'moves to the right and moves the setting device 5 from left to right, and at this time, the setting device 5 (+) (-) Power is not applied until the right welding end of the mesh band B is close to the welding needle bar 25, but the setting device 5 moves to the right welding needle bar 25. When the right welding end of the mesh band B is close to the welding needle bar 25 as shown in FIG. 3, the welding needle bar 25 is connected to the welding needle bar 25 by the spark adjusting sensors S ₁ and S ₂ . The power is automatically applied and the negative power is also applied to the mesh band (B) itself set at the bottom plate (5 ') and setting brackets (7) and (7'). In this way, the weld end of the mesh band B is melted between the welding end of the mesh band B and the welding needle bar 25 according to the energization state of the (+) and (-) power source by the short heat caused by the short state. .

At this time, when the switch valve 17 'is rotated again to the left side, air is supplied into the rear end side of the air cylinder 16, and the piston rod 16' is immersed to the right, so that the setting device 5 and the mesh band thereof are rotated. Welding is performed while (B) is moved to the left side, the ends of the left and right spiral coil material (B ₁ ) (B ₂ ) chained in a parallel state by the pin material (B ₃ ) are separated from each other. Since it is close to the end of the fin material (B ₃ ), the right-hand spiral coil material (B ₂ ) and the end of the fin material (B ₃ ) are welded integrally, and the left spiral coil material (B ₁ ) and the pin material ( The state in which the end portion of B ₃ ) is integrally welded is sequentially performed.

At the same time, the welded portion of the mesh band B is a known means for intensively ejecting a special heat shielding gas such as argon gas ejected from the tip 23 ″ of the welder 23. It is welded in a rounded state as shown in FIG. 4 by the partial power of the gas.

On the other hand, when the welding process of the mesh band (B) is completed as described above, withdraw it and insert the new mesh band (B) of the unprocessed state into the setting device 5, and then in the same manner as described above Repeatedly to weld the mesh band (B).

As such, according to the present invention, when the welded part is welded roundly, when the welded process is completed by fixing the pigmented mesh band B through the next fixing, both ends of the finished mesh band are manufactured without corners. Since the left and right spiral coil materials are welded separately to each pin material, flexibility is provided to the mesh band, and in particular, the present invention separates the welded portions of the mesh band separately, thus delaying work time and reducing productivity. It eliminates the shortcomings of welding, and it is possible to shorten the welding process time by improving welding productivity by continuously welding while setting the mesh band to the setting device that moves the welding process of the mesh band to the operation of the air cylinder. It is a practical design that can be expected.
