Description
99~
~ his invention relates to a drive mec~anism for controllably advancing a wire or similar elongate object to a work station such as a spot welder. The drive mechanism includes a wire spool holder, a wire guide and two conically shaped drive wheels which are adjusted to clamp, and controllably advance the wire or elonga-te ob-ject therebetween.
In operations such as spot welding it is frequently advantageous to supply wires of different diameters to the work ; station. The wire is conventionally supplied on spools which have a centrally disposed cylindrical opening. Usually, the diameter of the spool and indeed the width are related to the diameter of the wire wound thereon. A small diameter wire is usually wound on a smaller spool than might be used for a larger diameter wire. One of the features of this invention provides a simple but effective manner whereby different spool sizes ma~ be used in connection with the spot welder without complex set-up changes. A further difficulty encountered by the use oE different wire sizes in a spot welding operation relates to holding and advancing the wire in a ; 20 precise manner to the work station. Means to drive a wire of a specific diameter are, of course, known. The present invention, however, contemplates the use of a variety of diameters of wires~ and a holding and driving means is provided which readily accommodates the various wire diameters without requiring complex equipment change. A flexible wire guide is located between the spool holder and wire drive mechanism, the purpose of which is self explanatory.
Therefore, in accordance with the present invention there is provided a drive mechanism for advancing an elongate f- ~

object, ~or e~ample a wire, to a work s-tatlon, such as a spot welder. The drive mechanism comprises a pair of frusto-conical shaped wheels mounted so as to engage said object therebetween.
The wheels are mounted for rota-tion on separate shafts so that each frusto-cone is in a face to face relationship. Drive means are associated with a first wheel so that wheel is caused to rotate thereb~. Idler means associated with the shaft of the second wheel communicates with the drive means to cause the second wheel to rotate in a direction opposite to the rotational direction of the first wheel. The shaft of the second w~eel extends beyond the wheel and a tension adjusting means in the form of coil spring surrounding the shaf-t and a adjusting nut threadedly engaging the shaft is provided.
The tension adjusti.ng means is provided so that a wire or other elongate object entrapped between the conical-shaped wheels is securely held thereby. The adjustment, of course, provides means whereby the drive mechanism can accommodate ; various diameter wires. Rotation of the wheels ~orms a nip therebetween and causes the elongate object to b~ pulled or advanced through The drive m~h~n;~m may also include an adjustable spool holder comprising a pair of cone-shaped elements opposingly mounted on a common shaft, so that the spool may be rotatably secured therebetween. The distance between the cones may be adjusted as required to accommodate spools of diferent widths.
In a further embodiment of the present invention a Elexi.ble wire guicle is located between the drive wheels and the spool holder so as to align the wire wheels and to m~imize bend$ and k.inks in the wire.

ThereEore, in accordance with the present invention there is provided a drive mechanism ror use ln advancing an elongate object to a work station, comprising. first and second separate, parallel shafts; first and second frusto-conically shaped drive wheels mounted on the first and second shafts, respectively, each the dri~e wheel having a base, an ape~, and a beveled face extending there-between, the drive wheels being oppositely mounted on the shafts whereby the bases of the wheels face outwardly from each other and the apexes of the wheels face inwardly toward each other, the wheels being mounted in a face-engaging relationship to define a nip therebetween; drive means coupled to the first drive wheel shaft to impart a rotational force to the first drive wheel; idIer means mounted on the second drive wheel shaft and coupled to the second drive wheel and cooperating with the drive means to impart to the second drive wheel a rotational force opposit~ to the rotati.onal fo.rce of the first drive wheel; resilient bias means mounted on and coaxial with the second shaft and engaginy the second drive wheel to resiliently bias the face of the second drive wheel toward the face of the first drive wheel to provide a resilient gripping force be-tween the drive wheels at the nip whereby elongate objects of different diameters fed :into the nip will be resi~iently gripped by and pulled between the first and second drive wheels as the drive wheels are caused to rotate; and means th:readedly mounted on the second shaft and engaging the bi.as means for adjusting the bias means to vary the gripping force at the nip.

The aforementioned features of the present invention will be understood from the following detailed description in conjunction with the accompanying drawings wherein:
FIG. 1 is an elevational view of the drive mechanism in accordance with the present invention.
FIG. 2 illustrates, perspectively, the cone shaped drive wheels.
FIG. 3 is a cross-sectional view of the adjustable spool holder.
The preferred embodiment of the present invention, as illustrated in FIG. 1 includes a pair of frusto-conical shaped wheels 11 and 12. The wheels as illustrated are mounted ; on shafts 13 and 14 respectively. Shaft 14 associated with wheel 12 projects through the wheel and is fitted with 3 b ~
a tc.l3i~n adjusting nut 15, on the outer end. Wheel 11 i5 inscribed with a circumferential groove 16 at or near the mid-point of the -Eace of the cone. The groove may have a rounded cross~-section or a V groove. Wheel 11 has a gear 17 positioned on the base side of the cone, and attached to the shaft. A drive motor (not shown) is attached to the shaft by any suitable means whereby the shaft gear and conical wheel may be controllably rotated. The gear 17 is seen to cooperate with a second gear 18 attached to the shaft 14 on which wheel 12 is connected~ Gear 17 when rotated results in a rotation of second gear 18 which in turn causes the second conical wheel to rctate. As is understood, the second wheel 12 will rotate in the opposite direction to wheel 11.
As illustrated in FIG. 2 conical wheel 11 is mounted csm/
with the base ol -the cone towards the gear and the apex ~acing outwardly. Wheel 12 is mounted with the base of the cone facing outwardly and the apex Eacing the gear side. In this way, as will be apparent from FIG. 2 the beve]led surfaces of the conical wheels are in face to face contact. Wire 20 is located in groove 16 and entrapped therein by the biasing means shown in FIG. 2 as a helical spring 21. Threadedly adjusting nut 15 results in an adjustment o the biasing means 21 and thus adjusts the force applied by the wheels on the wire held therebetween. As will be apparen~ adjustment of the nut and hence tension on the biasing means will serve to accommodate various diameter wires, fed to the drive means.
The wheels may be machined from aluminiumr stainless steel or other suitable materials.
The wheels illustrated in FIG. 2 and the previous discussion contemplate a generally smooth face with a circumferential groove centrally located in the face of one of the wheels. It is to be understood that other means of improving the frictional force exerted on the wire may be employed. Such other means include serrations or knurling in the face of one or both wheels.
A flexible wire guide 30 is secured to the mounting arrangement in such a way that an elongate object such as wire 20 is directed to the nip formed by the two rotating wheels Il and lZ. More specifically, the guide is positioned so that wire 20 is directed to groove 16 formed circumferentially in wheel 11~ I'hus the wire 16 is entrapped between the wheels and fed to a subseq~lent work station (not shown) in controlled manner. The guide also serves to minimize bends and kinks in csr~/
-the wire as it is Eed to the drive wheels.
A spool holder 40 illustrated in FIGS. 1 and 3 is adapted to ~otatably hold a wire spool in a posi~ion whereby wire may be advanced to and through drive wheels ll and 12. The holder 40 includes a shaft 41 attached by any suitable means such as welding or threaded engagement to the support structure (not shown)~ The shaft projects from the support structure substantially parallel to the two sha~ts which carry the drive wheels. The outer end of the shaft is lQ threaded so as to threadedly receive a retaining nut 4~.
Between the support structure (not shown) and the retaining nut 42 combinations of spacers and cones are rotatably located on the shaft. Specifically, outer cone 43, and inner cone 44 provide a rotating surface for the axial opening in the wire spool 45. To accornmodate spools of different widths, as might be used for wire of different diameters, suitable spacers such as shown in FIG. 3 by reference numeral 46 are provided.
For example, for spools with a width of 4" inc~es,cone 43 is used in conjunction with spacer 46. Spools havlng a width of 8"inches are held by inner cone 44 and outer cone 43 with no spacers, and spools having a width of 12"inches may be held by inner ' cone 44, outer aone 43 and spacer 46 in a manner illustrated in FIG. 3.
Although the spool advantageously is free to rotate so that as the ~ire i5 pulled through the drive wheels, additional wire may be unwound from the spool. It is undesirable, of course, for an excess oE wire to be unwound as this will unavoidably result in kinks and bends in the loose wire.
csm/
Accordingly, the retaining nut should be tightened sufficiently to cause a drag or the spool as it rota-tes. This drag or friction on rotating surfaces acts as a brake -to the spool.
In operation a wire of the selected diameter will be pre~wound on a spool of a particular width. The spool is positioned between the cones and spacers in a manner whereby the spool may controllably rotate about the mounting shaft The free end of the wire is fed through the wire guide which in turn is positioned such that the wire is directed to the nip formed by the conical drive wheels and aligned with the groove is one of the wheels. As the wheels are caused to rotate, the wire is controllably advanced by ^the wheels and directed to a subsequent work station. A wire of a different diameter may be fed to a work station with a minimum of chan~es to the drive mechanism. The cone arrangement associated with the spool holder is changed in the manner previously described.
The free end of the wire is directed to the nip of the drive wheels, and the tension applied to one of wheels is ad~usted until the wire may be controllably advanced therebetween.
