Definitions

  • the invention relates generally to the fabrication of wire harnesses and to the equipment for the manufacture of wire harnesses.
  • This equipment relates generally to taping arrangements and more particularly to arrangements for the mechanized wrapping of tape about an elongated object, such as a bundle of wires undergoing fabrication into a wire harness.
  • the equipment further comprises a taping machine, a terminal assembling tool to a common bus connector, and loom tables.
  • wire harnesses The manufacture or fabrication of wire harnesses has assumed many forms and used various techniques, ranging from being highly manual-labor intensive to the use of a relatively significant level of automation. The former may be acceptable only if a low cost source of labor is available, whereas the latter requires significant capital expenditure and may be relatively inflexible.
  • the manufacture of high quality, cost-effective wire harnesses for motor vehicles may be a challenge, particularly where the high initial cost of equipment and variations in harnesses because of differing models of automobiles serve to argue against a high degree of automation. Yet the relatively high cost of the labor available also dictates against an inefficient use of such labor.
  • the common bus connector may include a plurality of terminals to which the individual wires, themselves being terminated, are respectively connected. Such connection of several terminated wires to a common bus connector often occurs in the formation of wiring harnesses, as for instance wiring harnesses for automotive vehicles.
  • the operation of connecting terminated wires to the respective terminals of a common bus connector has often been performed manually, particularly where it is included as one of the steps in the formulation of a wiring harness via a significant use of manual labor.
  • the manual interconnection of terminated wires with the terminals of the common bus connector may prove to be tiring to the operator, particularly where respective terminals are individually connected via the application of opposed manual forces. This may be further complicated if the positions of terminals on the connector are closely adjacent one another such that they interfere with or complicate the manual insertion of terminals.
  • Some types of wire harness manufacturing processes of the prior art have employed one or more so-called loom tables which are constructed to facilitate the formation of portions of the wire harness thereon.
  • loom tables typically include various supports positioned thereon in a pattern which assists in establishing the formation of the wire harness.
  • those loom tables are large, stationary and serve to establish the location of a work station, and they may be positioned at various locations within the fabrication area.
  • DE-A-2 507 384 which constitutes the prior art according to the preamble of claim 1 discloses an apparatus which is used for the fabrication of wire harness. It comprises means for transferring wire pieces, said means including among others an endless chain conveyor which is provided with gripping means at regular intervals, said gripping means being formed by movable clamping claws gripping the wire pieces during transportation by the conveyor means. Upper and lower guides are provided on the one side of the conveyor for guiding one end of the wire pieces when attaching the terminals thereto. On the other side there is provided a horizontal frame to support the center portion of the wires.
  • DE-A-3 327 583 discloses a method for the fabrication of wire harness. Separate wires are cut to desired lengths the insulation is removed and connectors are fixed to the ends of the wires. These prefabricated wires are bundled to form a harness.
  • the apparatus for carrying out the method comprises means for fixing the connectors to the wires and for supplying the wires. These means are followed by a connecting unit connected to the apparatus by means of the wire supplying means and has a coupling means for removably connecting the wires together through their connectors.
  • EP-A-0 290 641 discloses an apparatus fabricating wire harnesses, said harnesses being automatically fabricated with pre-cut and preconfigured ends in a robotic wire harness assembly system including a wire preparation subsystem, a wire reeling subsystem, a wire terminating subsystem, a wire queuing subsystem, a layup subsystem, associated robots, and a logic controller.
  • a wire harness assembling arrangement or system 10 in accordance with the invention.
  • the harness assembling arrangement 10 will be situated in a common area including at least a first region 11 for certain preliminary functions and a second region 12 throughout which the harness assembling function occurs.
  • a third testing region 13 might also be included.
  • the preliminary functions performed within the first region 11 result in precut, terminated wires 4, and typically include the large scale cutting of wires to predetermined lengths, appropriate stripping of insulation and the application and crimping of terminals 6 (seen in other figures) to one or both ends of most wires.
  • the machinery 14 may prepare one or both ends of a wire for receiving a terminal 6 or other termination without actually making the termination.
  • a human operator 15 typically controls the operation of cutting and terminating machinery 14. These wire cutting and terminating functions might be undertaken as batch operations.
  • This storage is represented by the wire storage shelving 18.
  • the precut and terminated wires 4 stored in shelving 18 are stored in channel trays 20 to be described hereinafter in greater detail.
  • the precut and terminated wires 4 are placed in respective channel trays 20 in accordance with their respective length, gauge, and/or type of termination.
  • the conveyor system 22 consists of one or typically a number of motorized conveyors 23, arranged in a serial or continuous fashion. More specifically, the conveyors 23 are arranged so as to form a line of continuous mechanized transport from an upstream end thereof designated 25 to a downstream end designated 26.
  • the conveyors 23 are of conventional design, including supporting framework 27 (seen in Figs. 2 and 3), moving belts or the like 28, and associated motors 29 for advancing the belts 28 in accordance with a desired schedule.
  • the motors 29 are typically controlled by a controller of known design which is preprogrammed to provide the desired schedule of control. Typically such controllers also possess the capability of manual override and control if such is desired.
  • a number of local work stations are situated or located along conveyor 23 of conveyor system 22. Since the present wire harness assembling system 10 relies principally upon a number of human operators 15 interacting with various types of tooling and machinery along the conveyor system 22, those work stations will, for convenience herein, be represented by the same symbols and reference numbers which represent the presence of a human operator 15. It should be understood, however, that a work station 15 might also be represented in certain limited instances by machinery capable of automated operation and/or by manually operated machinery to which an operator 15 moves from a different work station.
  • wire harness manufacturing and assembly equipment of various types and capability is located depending upon the one or more functions to be performed thereat.
  • Representative of such equipment are the terminal dispensing and crimping machines 30, the stands or mobile carriages (carts) 32 which typically support a number of the channel trays 20 which in turn contain the respective precut and terminated wires 4, stationary worktables 34, loom tables and particularly pivotable looms 36, one or more taping machines 38 and various receptacles or containers 40 containing the appropriate hardware to be included in the wire harness at that location.
  • Certain types of assembly tooling as for instance the terminal assembling tool 42, may also be located at the work station 15, and located upon a respective worktable 34.
  • the arrangement of the work stations 15 along the conveyor system 22 and the work functions performed thereat are designed to minimize or eliminate the need for the operator 15 at that work station to have to walk more than a step or two.
  • the operator 15 may be able to be seated at the work stations.
  • the wire harness 8 undergoing fabrication at any particular work station 15 is, generally speaking, at rest while at that work station.
  • the spacing between successive work stations 15 along conveyor 23 is substantially the same in most instances. It will be understood, however, that some variation in this spacing may occur to accommodate two operators at one or two work stations 15 performing functions on the same wire harness 8, but at opposite ends thereof.
  • the space between successive work stations is approximately 2-3 meters, the number of work stations is in the range of 8-12, and the conveyor belt 28 is incremented or advanced from one work station 15 to the next at intervals of several minutes.
  • the wire harness 8 is depicted in its completed form at or near the downstream end 26 of the conveyor 23.
  • Wire harness 8 has its beginning or inception at the upstream end 25 of conveyor 23, where, in its earliest "embryonic" form it is identified as wire harness 8a.
  • the wire harness takes on additional form and detail at each of the successive work stations and thus, is identified by a successive alphabetical suffix following the basic wire harness reference numeral 8.
  • the portrayal of the wire harness assembling system 10 in Fig. 1 depicts the conveyor 23 at the moment just prior to it being advanced from one work station 15 to the next.
  • the wire harness at each work station 15 is depicted in the condition or stage representing completion of the work provided at that work station.
  • the finished harness 8 is synonymous with an unused reference suffix 8l.
  • the completed wire harness 8 often includes 200-300 wires and may be more than 2 meters in length.
  • the harness 8 typically includes a number of different "arms" or “branches", each being comprised of differing numbers of wires. Typically, those branches are physically, if not also electrically, collected in a common region represented by a junction box 44 through which most of the circuits pass.
  • the junction box 44 may sometimes also be referred to as the "head” of the harness 8.
  • many of the branches of the completed wire harness 8 terminate at their opposite ends in respective multi-terminal connectors 46 of differing types and configurations.
  • the embryonic harness 8a includes a junction box 44 and relatively few wires and is, accordingly, relatively supple, deformable and of light weight. On the other hand, as formation of the harness 8 progresses, it becomes heavier and is relatively less supple.
  • the conveyor system 22 is provided with at least a primary trough 50 and perhaps also a secondary trough 52 on respectively opposite sides of the conveyor 23 along that portion of the conveyor toward its upstream end 25 in which the embryonic wire harness 8a, 8b, 8c, etc. is formed.
  • Troughs 50 and 52 extend along the upstream portion of conveyor 23 to permit the embryonic wire harnesses 8a, 8b, etc. to extend across, or transversely, of the conveyor belt 28 in a back and forth U-shape or serpentine fashion in which parts of the wire harness extend beyond the sides of the conveyor and hang or depend into the troughs 50, 52. It has been found most convenient to arrange the first two or three work stations 15 on one particular side of the conveyor 23 and to provide the primary trough 50 along that same side of the conveyor.
  • the primary trough 50 is of a generally deep U-shape in cross section and may typically extend 1.5-1.66 meter below the surface of the conveyor belt 28.
  • Primary trough 50 is sufficiently wide to conveniently accommodate a large junction box 44 resting therein as depicted in Fig. 2.
  • the trough 50 is sufficiently wide and smooth to facilitate the sliding of the embryonic harnesses 8a, 8b and associated junction boxes 44 therewithin as the conveyor belt 28 advances.
  • the depth of primary trough 50 is sufficiently shallow that various parts of the embryonic harness 8a, 8b and/or random components to be affixed to the harness may rest upon the bottom of the trough and are within reach of the operator 15 thereat.
  • the vertical walls inside of troughs 50 and 52, and particularly those walls adjacent conveyor 23, are relatively smooth and preferably continuous so as to prevent interference of the conveyor frame 27 with the embryonic harness 8a and junction box 44 as the conveyor belt 28 advances and to prevent chafing of the harness on the troughs.
  • the secondary trough 50 on the opposite side of conveyor 23 is somewhat more optional than the primary trough 50, and serves to facilitate the smooth flow of the embryonic harness 8a, 8b as it moves along the conveyor 23. Moreover, trough 52 serves to "catch" any components which may chance to fall free of the harness on that side of the conveyor. Since it is contemplated that the larger elements of the embryonic wire harness 8a, such as the junction box 44, will be in trough 50, the secondary trough 52 need not be as wide as trough 50.
  • the troughs 50 and 52 may be formed of any suitable material such as sheet metal, plastic or fiberglass which is contoured to the appropriate shape.
  • the troughs 50 and 52 are affixed to the conveyor frame 27 in a suitable manner, as by screws, bolts and/or brackets such that they are adequately supported at a level providing a smooth transition of the embryonic harness 8a, 8b from the conveyor belt 28 into and out of the troughs 50, 52.
  • troughs 50, 52 may be provided with curved lips at their uppermost ends to prevent chafing and cutting the wire harnesses 8a, 8b and/or the operators 15.
  • a junction box 44 is taken from a storage container 40 at the upstream end 25 of the conveyor.
  • Various wires 4 are taken from various ones of the channel trays 20 supported on carriage 32 also located near the upstream end 25 of conveyor 23.
  • the wires 4 are then connected with the junction box 44 by the first operator 15 to form the embryonic harness 8a.
  • additional operations on the wire harness 8a at that work station may include the application of additional terminals to one or more of the wires 4 via the terminal dispensing and crimping machines 30.
  • One or more other containers 40 near the upstream end 25 of conveyor 23 may contain various types of connectors 46 for connection with the terminals at the opposite ends of some of the wires 4 connected to junction box 44.
  • the embryonic harnesses 8a, 8b may be arranged across the conveyor belt 28 and thus compressed in the longitudinal direction, the entire length of the harness is easily within the reach of a single operator 15 at the respective work station. Thus, a single operator 15 may perform work functions on the entire length of the embryonic harness 8a without needing to move a significant distance within the work station. Moreover, the longitudinal extent of the conveyor belt 28 occupied by the embryonic harnesses 8a,8b, etc. is considerably less than will be required in the later stages of formation farther downstream.
  • portions of the embryonic harnesses 8a, 8b, etc. extend transversely of the conveyor belt 28, it has been found helpful to provide members on the conveyor belt 28 in that region for engaging the harness to assist with its positioning while work functions are performed and to further assist with moving the harness with the conveyor belt 28 when it is advanced.
  • These engaging elements may take the form of the pairs of fingers 54 seen most clearly in Fig. 2.
  • Each finger pair 54 is affixed at its base to the conveyor belt 28, as by a suitable bonding agent and/or mechanical fasteners, and includes a pair of fingers spaced from one another in the direction of conveyor belt travel. In this way, a portion of the harness 8a extending transversely of the conveyor belt 28 may be positioned between the fingers of member 54.
  • Each finger pair member 54 may be formed of rubber or a rubberlike material and the dimensioning and structure of the fingers is such that they may resiliently engage the harness therebetween.
  • the spacing between successive finger pair members 54 may be about 0.5 meter, more or less. Since the principal advantage of the finger pairs 54 described above is in the embryonic formation of the wire harness 8a, 8b, 8c, etc., they may be omitted from the conveyor belt 28 downstream if the conveyor system is formed of multiple separate conveyors 23 and associated conveyor belts 28, as is typically the case.
  • Each channel tray 20 typically receives precut terminated wires 4 of a particular type and length. In this way, there is no mixing of wires 4 of different types within a single channel tray 20.
  • Channel trays 20 are generally U-shaped, are elongated and are open at least at a discharge end, and preferably at both ends.
  • the channel trays 20 may be of differing lengths, depending principally upon the length of wires 4 to be stored therein, with the majority ranging in length between 1 and 2 meters although they may be shorter or longer.
  • Such flat-bottom U-shape configuration appears to afford a more even distribution of the wires 4 contained therein and reduces the incidence of tangling which would interfere with the removal of individual wires from the tray.
  • the curved cross section of channel tray 20a results in a greater number of wires 4 being at the center of the tray and thus contributes somewhat to tangling.
  • the channel trays 20 are formed of any suitable, relatively rigid and durable material, as for instance, metal, plastic or fiberglass.
  • wires 4 in a particular channel tray 20 are terminated at only one end, it is that terminated end which is presented to the operator 15 when the tray 20 is supported in position on a carriage 32 adjacent to a particular work station.
  • supported channel trays 20 may be positioned on either, or both, sides of the conveyor 22 relative to the position of the operator 15 who will be drawing wires 4 from those trays.
  • Perhaps the most common arrangement and that which permits easiest access by operator 15 to a relatively large number of channel trays 20, is that in which the carriage 32 supporting those trays is positioned opposite the operator 15 across the conveyor 23, as seen specifically in Figs. 2 and 6.
  • a pair of such trays may be joined at their respective forward ends by a suitable connector or fastener, such as hinge 55, to form a double tray designated 20′ in Figs. 3 and 4.
  • a suitable connector or fastener such as hinge 55
  • one portion of each of the long wires 4 is contained in one of the channel trays and the remaining portion is contained in the other, with the wires transitioning between trays just beyond the forward ends of the trays in the region of the hinge 55 so as to be readily available for removal by an operator 15.
  • the connecting hinge 55 provides a convenient means for joining the two trays 20 forming the combined unit 20′ for ease of handling during loading and transport.
  • the stands or carriages (carts) 32 upon which the various channel trays 20 are supported may be of relatively simple design and inexpensive construction. In some few instances, the stands 32 may be permanently stationary and thus have no requirement for mobility. In most instances, however, it has been found desirable for the stands or carriages 32 to be mobile, and thus some form of rollers or wheels 56 are provided on cross-members 57 at the base of carriage 32. In some instances it may be desirable to reduce or "sweep" the profile of the cross-members 57 and wheels 56, as by making them adjustable via struts 59 in the manner depicted in broken line in Fig. 3.
  • the channel trays 20 are simply rested upon crossarms or shelves 58 which form part of the rigid structural framework of the carriage.
  • the flat base of channel tray 20 may simply rest upon a flat surface of a horizontal crossarm 58.
  • a number of channel trays 20 may be supported in side by side relation on any one crossarm 58, and the carriages 32 typically also include crossarms 58 at several levels to accommodate channel trays at those differing elevations.
  • carriages 32 described above provide horizontal orientation of the associated channel trays 20, a carriage 32′ is constructed such that the trays 20 are supported thereby in a near vertical orientation, as depicted in Fig. 5.
  • These stands or carriages 32′ may be of somewhat simpler construction than the carriages 32 and, because of the vertical orientation of trays 20, will occupy relatively less floor space.
  • clamps 60 may be mounted to the undersurface of trays 20 at or near the forward, upper, or discharge end thereof for engaging a bundle of wires 4 which hangs over that same end of the channel tray. In this way the wires are prevented from falling down within the channel tray 20 when it is in its vertical orientation and the ends are conveniently presented for easy removal.
  • Each of the loom tables 36, 36′ includes a number of wire or harness-supporting jigs 62 mounted on the upper surface thereof in a predetermined pattern for aiding in the formation of the harness 8 or, more likely, a subassembly or branch to become part of the main harness.
  • the jigs 62 typically include a base portion 63 which is mounted to the loom table 36 or 36′, and a vertical support portion 64 extending upwardly therefrom and being bifurcated at its upper end to form a pair of harness-supporting fingers 65.
  • the arrangement of the jigs 62 on loom tables 36, 36′ is such as to define multiple wiring and branch paths during the formation of the harness or a harness subassembly.
  • the loom tables 36′ are typically on wheels to permit easy positioning and repositioning of the tables in the region of the conveyor 23.
  • movable loom tables 36′ are positioned sufficiently close to the conveyor 23 that relatively few steps are required by an operator 15 to move a harness or a harness subassembly between the conveyor and the respective loom table.
  • the wheeled loom table 36′ is capable of general movement in the region of a work station and may in fact be positioned such that an operator/work station 15 is positioned between the loom table 36′ and the conveyor 23.
  • the loom table 36 may be even closer to the conveyor 23 and is capable of certain limited displacement by an operator 15, as by being pivoted, between an operating position and an idle position, as depicted in Figs. 1 and 6 adjacent wire harness 8f.
  • the loom table 36 is illustrated at its idle position in solid line, and at its idle position in broken line.
  • the operating position places the loom table 36 closely adjacent and parallel to the conveyor 23, whereas the idle position is achieved when the table 36 is rotated approximately 90 degrees away from the conveyor about a pivot axis 66 which is remote from the operator 15 and generally near the conveyor 23.
  • the loom table In its operating position, the loom table is positioned for easy access by the operator 15 to perform the various work functions on the harness or harness subassembly as required. On the other hand, when such work is completed, the harness or subassembly may be conveniently removed from the loom table 36 and placed on the conveyor belt 28, and the loom table may be pivoted to its idle position, thereby affording the operator increased spaced for the performance of other work functions at that particular work station.
  • a journal or gudgeon 68 may be mounted to the conveyor frame 27 and a pivot pin or pintle 69 extends downwardly from the underside of loom table and through the gudgeon 68 to provide the pivot axis 66. It may be desirable to provide some form of lock or clamp or detent associated with gudgeon 68 and pintle 69 so as to retain the table 36 at a selected position about the pivot axis.
  • One relatively simple way of providing the detent is to provide a pin or dog extending radially from the pintle 69 near its upper end and to contour the upper end of the gudgeon so as to provide detenting recesses for the pin at desired angular locations thereabout.
  • Tool 42 is designed to easily and accurately accomplish the connection of several terminated wires 4 to a common bus connector 70.
  • Common bus connector 70 is utilized to connect those several wires to a common electrical potential, as for instance B+ or ground in an automotive electrical system.
  • the current-carrying capacity of the wires 4 which are connected to bus connector 70 is typically greater than that of many of the other wires in the wiring harness 8.
  • the terminals 6 on the ends of the respective wires 4 are of a female-type, and are adapted to receive and be connected to the male, spade-type terminals 71 of bus connector 70.
  • the bus connector 70 in the illustrated embodiment includes three such male terminals 71 extending forwardly from a common base portion 72 in substantially coplanar parallel relation. Side or end fingers 73 extend forward from each end of the common base 72 of connector 70.
  • each of the male terminals 71 extends from an edge of the common base portion 72, whereas the end fingers 73 are created by respective 90 degree bends in that base portion and thus extend in respective planes which are perpendicular to the plane containing the male terminal 71.
  • the end fingers 73 may themselves subsequently be placed in electrical connection with other conductive members.
  • the terminal assembling tool 42 aids in accurately positioning the terminals 6 relative to the male terminals 71 of common bus connector 70 and further contributes not only to the easy connection of those elements but also, to the removal of the connected terminals from that tool.
  • Tool 42 includes first and second jigs 75 and 77 respectively.
  • Jig 75 is structured to receive the terminated ends of several wires 4.
  • Jig 77 is structured to receive the common bus connector 70 oriented in a substantially horizontal disposition.
  • Jigs 75 and 77 are mounted on a base member 78 in a manner allowing one of the jigs to move relatively toward and away from the other between relative proximate and distant positions respectively corresponding with a connecting position and a load/unload position.
  • jig 75 remains stationary and jig 77 is capable of linear motion transversely of base 78.
  • a pneumatic actuator such as the piston and cylinder 80, is connected with the base member 78 and the jig 77 to effect and control the displacement of that jig relative to jig 75.
  • the piston arm 81 of actuator 80 is positively connected to jig 77, as by welding or threaded engagement or the like, to positively reciprocably displace that jig.
  • the cylinder of actuator 80 is rigidly mounted and provides significant lateral stability to jig 77. However, to the extent that further lateral guidance of that jig is required, a raceway may be machined in the base member 78 to assure alignment with jig 75.
  • a chamber or cavity 82 which is open in both the forward and upward directions.
  • the cavity 82 is adapted to receive a common bus connector 70 deposited from above, and is open at its forward end to permit mating engagement with the terminals 6 supported in jig 75.
  • the common bus connector 73 disposed horizontally as depicted in Fig. 7b, a clearance exists beneath the undersurfaces of the male terminal 71 sufficient to permit the insertion thereon of the female terminals 6.
  • Jig. 75 includes several longitudinally extending slots 83 in the upper surface thereof for receiving the respective wires 4. More specifically, the grooves or slots 83 define sidewalls 84 which are undercut near their forward ends to provide seats 85 for the terminals 6. The undercut in the walls 84 is such that the terminal seats 85 contain the terminals 6 captive in both a vertical and lateral direction when inserted and seated therein as depicted in Figs. 8 and 9.
  • jig 77 is shown in its load/unload position, displaced from jig 75.
  • the terminal 6 of a terminated wire 4 may be loaded into jig 75 by disposing the terminal forwardly of the forward end of jig 75 and moving the terminal and the wire 4 downward until the terminal is at the level of the terminal seat 85. Rearward tensioning of wire 4 then serves to seat the terminal 6 in terminal seat 85.
  • This same operation is repeated for the other two terminated wires (not shown) with respect to the other two slots 83 in jig 75.
  • the common bus connector 70 is loaded into jig 77 by dropping it into cavity 82 in the orientation depicted in Fig. 7b.
  • jig 77 which define cavity 82 are sized and configured to orient common bus connector 70 such that its terminal 71 are in constant alignment with the female terminals 6. Actuation of jig 77 via actuator 80 serves to bring the male terminals 71 into mated engagement with the female terminals 6, thus completing the connection.
  • Retaining elements 86 are formed at the forward end of the jig 77 by a pair of projections extending transversely a short distance toward one another to provide a partial closure to the forward end of cavity 82. More specifically, retaining elements 86 extend across the forward ends of the end fingers 73 on the common bus connector 70. Following connection of the terminals 6 and their associated wires 4 to the common bus connector 70, actuator 80 operates to withdraw arm 81 and move jig 77 rearward to the load/unload position. During that motion, the retaining members 86 on jig 77 engage the end fingers 73 and the common bus connector 70 rearward also.
  • Such rearward displacement of a common bus connector 70 dislodges the female terminals 6 from their seated positions in jig 75, thus facilitating removal of the connected wires and connector from tool 42 by a simple lifting upward of the several wires 4 in unison to remove connector 70 from cavity 82.
  • wire harnesses 8 At various stages in the formation of wire harnesses 8, it is desirable and necessary to gather and bind certain ones of the wires to form branches within the harness. In some instances, those branches will terminate in connectors or other types of electrical termination.
  • an improved taping arrangement is depicted at the work station containing taping machine 38 and adjacent to which the harness 8i is positioned. Both the taping machine 38 and the arrangement of which it is a part are of improved design, as discussed in the following description with particular reference to Figs. 10-12.
  • a platform 88 there is depicted the taping machine 38 mounted for translation along a pair of rails 87 which are in turn mounted to and supported by a platform 88.
  • the platform 88 is pivotally mounted to and supported by the frame 27 of conveyor 23 in the same way as pivotable loom tables 36, as by a gudgeon 68 and pintle 69 of the type earlier described.
  • the work platform 88 may be long and narrow and formed of a rigid material such as metal, wood or plastic.
  • a mechanism for gripping or clamping the harness such as the clamping mechanism 89.
  • the clamping mechanism 89 is rigidly mounted to platform 88 and extends upwardly therefrom for releasably engaging a bundle of wires which form a branch of harness 8i, to permit the application of a tensioning force to the harness branch during the taping thereof.
  • the clamping mechanism 89 may be of any suitable construction and typically includes a pair of jaws 90a, 90b, one or both of which are movable vertically between clamping and release positions by means of a manual actuating arm 9.
  • the lower jaw 90a is stationary and the upper jaw 90b is moved vertically by actuation of the arm 91 in a vertical plane about a horizontal pivot axis.
  • Actuating arm 91 may be pivoted downward from its release position shown in Fig.
  • jaws 90a and 90b firmly grip a branch of the harness placed therebetween.
  • the jaws 90a, 90b may be concavely contoured to the general circular shape of a harness branch.
  • a spring or other bias element is typically associated with one or both of the jaws 90a, 90b such that they resiliently and yieldably engage harness branches of differing diameters.
  • Platform 88 serves as a mounting frame for the parallel rails 87, which in turn support the taping machine 38 in sliding relation therewith via slide bracket 92 which slides along the rails between a pair of adjustable stops 93 positioned toward relative opposite ends thereof.
  • the stops 93 may be positioned on only one of the rails 87 and are manually adjustable as by thumbscrews.
  • taping machine 38 includes a two-piece housing 94, a two-piece orbiting disc or plate 95 and a tape dispensing arrangement, such as the spool of tape 97 mounted on orbiting plate 95 via spindle 98.
  • the orbiting plate 95 is driven by motor 96 via a pinion 100 in driving engagement with an annular bevel gear 99 on the face of plate 95.
  • the orbiting plate 95 includes a circular central opening 102 through which the branch of the wiring harness to be taped extends during the taping operation.
  • the plate 95 may be of a suitable material such as metal, plastic or a composite.
  • both the housing 94 and the orbiting plate 95 are formed of two pieces, and the housing is hinged to permit being opened at a forward end to create a mouth 104 through which a wire harness branch may be admitted to and removed from the central opening 102 without requiring axial movement of the branch.
  • the lower portion of housing 94 and of orbiting plate 95 are angularly coextensive and are less than 180 degrees, whereas the respective upper portions of each are somewhat greater than 180 degrees.
  • the lower portion of housing 94 is connected to the upper portion via a hinge mechanism 106.
  • Hinge 106 is in turn connected to a pneumatic actuator 108 via linkage 109. Operation of the actuator 108 serves to move the lower portion of housing 94 up and down between closed and open positions respectively.
  • the housing 94 is C-shaped in cross section to provide a housing and raceway for the two-piece plate 95 which orbits therewithin.
  • the outer circumference of the two-piece orbiting plate 95 is sufficiently narrow to fit within the housing 94, but sufficiently wide to include several slots extending radially therein about the circumference for the mounting of several respective roller bearings 110.
  • the roller bearings 110 are mounted in position by respective pins 112 which extend in an axial direction through plate 95 and upon which the bearings are mounted for rotation.
  • the roller bearings 110 provide the principal supporting contact between the housing 94 and the orbiting plates 95.
  • a connecting bracket 118 spans the two halves of the housing 94 and includes a slotted keyway 119 in which a key (not shown) associated with one of the halves slides in order to glide a relative opening and closing motion between the halves.
  • the orbiting plate 95 is formed in two complementary portions, the portion which is being driven at any moment by pinion 100 serves to drive or push the other plate portion such that it follows.
  • Pinion 100 spans both halves of the orbiting plate 95 at the two positions of interface therebetween.
  • an engaging hinge having a female fastener member 120 on one lip of the housing and a locking pin 121 controlled by pneumatic actuator 122 positioned on the other lip of the housing. Control of the actuator 122 serves to move the locking pin 121 into and out of locking engagement with the female fastener member 120.
  • the two portions of the orbiting plate 95 each stop in positions which are angularly coextensive with the two halves of the housing 94 when the taping machine is to be opened. This assures that the opening of mouth 104 is relatively wide and further, that there is little or no likelihood of the orbiting plate portions becoming separated from the respective housing portions.
  • Cylinder 126 operates to apply a braking/locking force to the upper orbiting plate 95 to lock it in correct angular position as detected by detector 124.
  • Pneumatic cylinder 126 may act to move a brake or lock member into and out of braking and/or locking engagement with the orbiting plate 95.
  • the motor 96, and the actuator cylinders 108, 122 and 126 are pneumatically driven and are controlled in accordance with an electric program control provided by an OMRON C28K Controller (not shown) in a manner commensurate with the present description.
  • Inputs to that control are provided by START/STOP and OPEN/CLOSE control buttons (not shown) controlled by an operator 15 and additionally by an electrically input from the inductive detector 124.
  • Appropriate actuation of the OPEN/CLOSE control buttons effects the respective opening or closing of the taping machine 38 via actuator 108 and the respective unlocking or locking of fastener 120, 121 via actuator 122.
  • the work platform 88 will typically be pivoted to a position adjacent the conveyor 28 and one end of the branch to be taped will be clamped in the clamping mechanism 89.
  • the harness branch will then be moved through the open mouth 104 of taping machine 38 into the central opening 102 and the other end of that branch may then be supported in the bifurcated support 65.
  • the operator 15 may provide a manual tensioning of the harness branch against the resisting clamping force of the mechanism 89.
  • the taping machine 38 is then closed, the tape 97 is led to the harness branch and the motor 96 is then energized to begin the taping operation.
  • the taping machine 38 is manually moved along the rails 87 from one stop limit 93 to the other to perform the tape winding operation. Upon reaching the other limit 93, the operator actuates the STOP button, then severs the tape, as with a knife, and opens the taping machine 38 to permit the removal of the harness branch and its return to the conveyor belt 28.
