    BACKGROUND OF THE INVENTION
    [0001] The present invention deals with an apparatus that is useful to solve a major problem in the handling of coiled wire. Coiled wire is commercially wrapped, transported and stored in a coiled configuration, most of the time using a storage container.
    [0002] As a consequence, it takes on a certain mold for the metal in such a way that when the wire is unwound for use, it forms a sine wave configuration and if the wire is not handled correctly this sine wave configuration (the mold of the sine wave) wire) can become helical in nature and can lead to interlaced, twisted or curved wire.
    [0003] In use for welding, where the wire is fed to a welding gun, the wire enters the gun through the rear of the gun and is subjected to the electrical energy in which it melts and is placed in channels in the metal to be welded to form a solder fillet.
    [0004] In cases where only short segments of the wire are needed, the wire mold does not commonly make a difference, but where long weld threads are needed, the wire must be checked before entering the welding gun.
    [0005] If not controlled, the wire, after leaving the tip of the welding gun, and before it is melted, typically bends in any given direction and does not rest in the channel to form the fillet. In this way, a person is forced to use short strands of wire (which do not retain the mold of the coiled wire), or the wire is short enough that it can be folded by hand to get rid of the wire mold and provide a piece wire straight.
    [0006] Even in longer segments, the wire, if not controlled, tends to rewind, that is, it tries to recover its original mold, or it bends out of linearity and causes breaks in the equipment, which causes interruption of the welding process and a possible shutdown of the equipment for repair. It also provides twisted and folded yarn which is useless for reuse and expensive to replace.
    [0007] The set provided by this invention assists in removing the wire from the stored package and helps to supply the wire to a wire feed by modifying the sine wave mold of the stored wire before it forms a helical coil and presents problems. This device is especially useful for transferring long wire segments, sometimes as long as up to a hundred feet in length.
    [0008] The device provides a simple system of supplying straight wire to a welding gun and, in addition, allows the positioning of the plastic conduit in which it is loaded throughout the manufacturing facility, on and around the equipment found in conventional manufacturing situation so that the yarn does not provide an unsafe condition in the manufacturing facility. The person filing the patent is not aware of any such set in use today. THE INVENTION
    [0009] Thus, what is revealed and claimed here is a set for moving wire from one point to a second point distant from the first point. The assembly comprises a first unit comprising a wire straightener in which the wire straightener is comprised of a mounting plate, the plate having a front flat surface, a rear flat surface, a back edge and a forward edge.
    [00010] There is a mounting means mounted on the front flat surface and close to the rear edge, the mounting means having an opening centered through it. The opening contains a hollow inlet guide tube attached to it. The tube extends through the opening in such a way that it extends back and forth from the mounting medium.
    [00011] A yarn guide pulley is mounted on the front flat surface in such a way that the bottom edge of the yarn guide pulley contacts a yarn being processed through the unit.
    [00012] There is a first roller straightener pulley mounted on the front flat surface and under the wire guide pulley. The first roller straightener has a centered shaft.
    [00013] There is a vertically adjustable central pulley roller mounted on the front flat surface and in front of the first roller straightener pulley and a second roller straightener pulley mounted on the front flat surface and in front of the adjustable central pulley. The pulley has a centered shaft. The first roller straightener pulley shaft and the second roller straightener pulley shaft are linearly aligned. There is a slotted vertical opening near the front edge of the mounting plate.
    [00014] There is a second unit comprising a wire drive, puller and driver, the wire drive puller and driver having a housing mounted on a back plate.
    [00015] The housing has a front wall and a rear wall and there is an opening centered on the front and rear wall, each opening having a guide bushing in it. The front bushing has an outlet guide tube mounted therein, the outlet guide tube extends back and forth from the guide bushing.
    [00016] The second drive housing contains an intermediate drive roller and a driven drive roller, the intermediate roller and the drive roller both have centered axes. The intermediate roller and drive roller contact each other on a portion of the outer circumferential surfaces.
    [00017] The second unit housing is mounted on a base which rises above a mounting block having a bottom surface, where the mounting block has two slotted openings through it. There are a pair of threaded screws on the bottom surface of the base.
    [00018] The mounting block extends to and behind the rear surface of the first unit mounting plate. The mounting block has an extension loosely attached to the rear surface of the first unit mounting plate by fasteners through the slotted vertical opening near the front edge of the first unit mounting plate.
    [00019] In a second embodiment, there is a method of moving wire from one point to a second point that is distant from the first point using the set as described above.
    [00020] The method comprises employing a set as discussed above and as a first step, providing a storage unit containing coiled yarn.
    [00021] A person then moves an advanced end of the stored wire to the inlet guide tube of the first unit and subsequently moves the wire under the wire guide pulley, on a circumferential surface of the first roller straightener pulley, under a circumferential surface of the adjustable central pulley roller, on a circumferential surface of the second roller of the straightener roller to modify the wire mold and then to the guide bush of the rear wall of the second unit, between circumferential surfaces of the roller intermediate drive and driven drive roller, for the outlet guide tube, for a plastic conduit, said plastic conduit being of a length to load the wire internally to a welding gun being used at a certain distance from the storage unit of wire.
    [00022] The second unit is then allowed to supply the wire through the conduit to the welding gun at a predetermined rate provided by the second unit.
    [00023] "Pulley" as used here is a wheel or roller with a notch on its circumferential surface to guide a belt, rope, wire or cable. BRIEF DESCRIPTION OF THE DRAWINGS
    [00024] Figure 1 is a total side view of a set of this invention in which, for purposes of description in that specification, the leading end is on the left.
    [00025] Figure 2 is a top view of the assembly block of the second unit of the set. DETAILED DESCRIPTION OF THE INVENTION
    [00026] The set is comprised of two units that work in combination, namely, a first unit 1 which is a straightener and a second unit 2 which is a wire drive puller and driver.
    [00027] The wire straightener 1 is comprised of a mounting plate 3 which is used to assemble the components of the first unit in a predetermined mode, namely, in such a way that the components are linearly aligned from right to left ( the direction of the flow of the wire being processed through the unit). The mounting plate 3 is also used to stabilize the various components of the first unit 1.
    [00028] The mounting plate 3 has a front flat surface 4, a rear flat surface 5 (not visible in this figure), a rear edge 6 (on the right) and a forward edge 7 (on the left).
    [00029] There is a mounting means 8 for mounting a wire guide 9. Mounting means 8 is mounted on the front flat surface 4 and close to the rear edge 6. Mounting means 8 has a centered hole 44 through it, the opening 44 containing a hollow inlet guide tube 10. Tube 10 extends back and forth in such a way that it extends beyond the mounting means 8.
    [00030] There is a yarn guide pulley 11 mounted on the front flat surface 4 such that the bottom edge 12 of the yarn guide pulley 11 contacts a yarn 14 being processed through the unit. The wire guide pulley 11 has a centered axis 15 such that it allows it to rotate in the opposite direction to the forward path of the wire 14.
    [00031] There is a first roller straightener sheave 16 mounted on the front flat surface 4 and below the yarn guide sheave 11 such that the yarn guide sheave 11 keeps the yarn 14 essentially flush with the top of the circumferential surface 17 of the first roller straightener roller 16. Therefore, it is meant that the thread 14 at that point is maintained in such a way that it does not have a significant arcuate portion. The first roller straightener sheave 16 also has a centered shaft 21 that allows it to rotate in the direction of travel in front of the wire 14.
    [00032] There is a vertically adjustable central pulley roller 18 mounted on the front flat surface 4 and in front of the first roller of the straightener roller 16. This pulley 18 has a centered shaft 22 that will allow rotation of the pulley 18 opposite the displacement of the wire 14 The pulley 18 is adjustable in a vertical manner such that the wire 14 maintains contact with the first roller straightener roller 16 and the second roller straightener roller 19. This action of the pulleys 16, 18 and 19 applies pressure in the configuration shown, to the wire 14, and modifies the mold of the wire 14 such that it is essentially straightened.
    [00033] The second roller straightener roller 19 is mounted on the front flat surface 4 and in front of the central adjustable pulley 16. The roller 19 has a centered axis 20 which allows it to rotate in the direction of the forward path of the wire 14. At that point, as the wire 14 exits the second roller straightener sheave 19, it forms a light arcuate configuration 23, but due to the fact that the wire 14 has been straightened, there are no significant problems associated with the formation of such an arcuate configuration 23 in this point. In addition, the arcuate configuration allows flexibility to adjust the wire level 14 in the first unit 1 to be essentially flush with the opening 13 in the rear 24 of the wire drive, puller and driver 2.
    [00034] It should be noted that the axes 20 and 21 are linearly aligned so that the path of the wire 14 is aligned on the pulleys 16, 18 and 19.
    [00035] The pulleys 16, 18 and 19 are generally made of some durable plastic, however soft or similar, which has ceramic or similar incorporated in it. The only critical aspect of the pulleys is that they do not severely rub metal wire 14 as it is being pulled through the pulleys; therefore, it is generally prudent to supply such pulleys as plastics with particles embedded in them to provide a little friction for traction purposes. Polyethylene with ultra high molecular weight incorporated with ceramic particles was considered useful, as well as phenolic and urethane resins. Metal pulleys can be used here, but there is a significant abrasion of the metal wire 14.
    [00036] There is a slotted vertical opening 25 near the forward edge 7 of the mounting plate 3. This slotted vertical opening 25 is used in combination with the screws 26 to adjust the second unit 2 to align with the first unit 1.
    [00037] The second unit 2 is a wire actuator and puller, that is, this second unit 2 both pulls the wire 14 from the first unit 1 and drives the wire 14 into the conduit 27 for transportation.
    [00038] The second unit 2 is comprised of a housing 33 which has a front wall 28 and a rear wall 24. There is an opening 29 in the front wall 28 and an opening 13 in the rear wall 24. Each opening 13 and 29 have a bushing therein, namely 30, on the rear wall 24 and 31 on the front wall 28. The bushing 31 has an outlet guide tube 32 through which the wire 14 passes and is guided in this way. It should be noted that the outlet guide tube 32 extends beyond bushing 31, back and forth. The outlet guide tube 32 has a plastic conduit 27 attached to it, which is the conduit that the wire 14 is transported through for its final use in the welding gun. The conduit for purposes of the present invention can be any flexible conduit, but it is preferred to use plastic or elastomer materials that will provide protection against abrasion of the metal as it slides through the conduit.
    [00039] The second drive housing 33 contains an intermediate drive roller 34 and a driven drive roller 35, the intermediate roller 34 and the drive roller 35 with each axis centered, 36 and 37 respectively, which allow the rollers rotate, the intermediate roller 34 in a direction opposite to the forward movement of the wire 14, and the drive roller 35 in a direction consistent with the movement of the wire 14.
    [00040] It should be noted that the intermediate roller 34 and the drive roller 35 contact closely with each other to provide pressure on the wire 14 to create sufficient friction to move the wire 14 forward. The contact is obviously between the circumferential surfaces of the rollers.
    [00041] The second unit 2 is mounted on a base 38, which lifts above a motor mounting block 39, having a bottom surface 40, on which the mounting block 39 has two parallel openings, slotted 41. There is a pair of screws 43 threaded on the bottom surface 40 of the base 38.
    [00042] With reference to figure 2, a top view of the mounting block 39 is shown showing two slit openings 41. In addition, the extension of the mounting block 42 is shown with a pin 26, the extension mounting behind the mounting plate. assembly 3 and the screws 26 securing through the slotted opening 25 on the forward edge 7 of the mounting plate 3.
    [00043] Turning now to the other embodiment of the present invention which is a method of moving yarn from one point to a second point distant from the first point, the method comprises employing a set as discussed above.
    [00044] For the method, a storage unit containing coiled wire that can be purchased commercially is provided. A person then moves an advanced end of the stored wire into the entry guide tube of the first unit.
    [00045] Subsequently, the yarn is pulled under the yarn guide pulley, on a circumferential surface of the first roller of the straightener roller, under a circumferential surface of the adjustable central pulley roller, on a circumferential surface of the second roller of the straightener pulley. roller to modify the wire mold, and then into the guide bush of the second unit's rear wall, between circumferential surfaces of the intermediate drive roller and the driven drive roller, into the outlet guide tube, into a plastic conduit, the plastic conduit being of a length to carry the wire internally to a welding gun being used some distance from the wire storage unit.
    [00046] Subsequently, allowing the second unit to supply the wire to the welding gun at a predetermined rate provided by the second unit.
    [00047] Although electric motors can be used, it is preferred that the second unit 2 is an air driven system to connect the drive motor fixed to the drive roller 35. The use of air eliminates the need for energy / electrical interface for turn the unit on and remove problems and adjustments using a power source. It also allows use in those areas of the world that do not have sufficient sources of electricity to connect such equipment. The air driven system also allows a positive charge to be applied to the drive rollers while being stopped, without the accumulation of heat or current. Stopping air motors (as opposed to electric motors) has little to no effect on wear issues and can be regulated to provide the appropriate load.
    [00048] It should be noted that the wire 14 is forced through a series of three specific plastic wheels (polyethylene with ultra high molecular weight) reinforced with ceramic fiber that mechanically drain the wire 14 to force it to assume the shape or mold of the runs in series of three.
