Definitions

  • ABSTRACT A method and apparatus for forming a strip of nails.
  • a plurality of heated nails is conveyed with shanks positioned in a side-by-side closely-spaced array past tape feeders which direct respective strips of thermoplastic tape transversely and tangentially over the upper and lower sides of the array.
  • Successive low pressure and high pressure heated air currents are directed against both upper and lower tapes to envelop each shank positively with a uniform thickness of plastic and form a unitary strip of nails.
  • This invention relates to a method of producing strips of fasteners such as nails and the like and apparatus for assembling fastener strips useful in fastener driving tools. Strips of nails and fasteners of similar type. having their shanks joined by numerous different expedients, have been in growing demand from users of fastener driving tools. Along with the growth in usage has come a demand for improved types of fastener strips affording greater reliability, freedom from jamming, and improved holding power after having been driven into a workpiece.
  • One such improved fastener strip is disclosed in the copending application of Lawrence S. Shelton for Fastener Strip," Ser. No. 354,313, filed Apr. 25, I973, assigned to the assignee of the present invention.
  • fastener strip assembly apparatus for use with thermoplastic tape and a fiat parallel array of fasteners having elongated shanks disposed side-by-side and defining uniform gaps between said shanks.
  • the apparatus includes tape dispensing means for directing first and second strips of thermoplastic tape transversely across the shanks of the array on opposite sides thereof.
  • the strips are then made to affix the fasteners permanently in their arrayed relationship by the provision of means for forcing heated air upon both strips so as to urge said strips inwardly within the gaps between the shanks into contact about said shanks, thereby enveloping at least a portion of each shank and joining the array of fasteners together to form a unitary fastener strip.
  • the apparatus thus obviates the need for any mechanical contact with the tape to effect its formation about the shanks, so that problems caused by the adhesion of heated tape to such mechanical components cannot arise, and the uniformity of the tape thickness about each shank is optimized.
  • FIG. I is a partially schematic view of the fastener strip assembly apparatus of the invention, showing the manner in which thermoplastic tape is applied to the shanks of an array of nails in plan view to produce a unitary strip;
  • FIG. 2 is a schematic enlarged view of a portion of the apparatus of FIG. 1 in more detail, showing the array of nails in cross-section;
  • FIG. 3 is an elevation view of a finished strip of nails produced in accordance with the invention.
  • modified nails 11 which are common nails having elongated shanks 12 that have had one side of their heads 15 removed along a chord thereof so that the chord sections preferably are slightly spaced from, or protrude slightly beyond, the periphery of the shank 12 on the modified side.
  • heads 15 thereafter resemble a half-moon.”
  • the apparatus causes the nails to be moved through a series of stations, where: (I) the modified nails are received and collated; (II) the modified and collated nails are deposited on a conveyor which maintains them in an aligned side-by-side parallel spaced relationship to define nail array 10; (III) a strip of tape 14 of thermoplastic material is applied to the lower shanks of the nails 10 transversely to the orientation of the shanks, as well as tangentially of the shanks.
  • a collating apparatus which includes a vibratory feeder 2 is continuously supplied with modified nails II and positions the nails so that the heads thereof are adjacent one another and the shanks thereof are in side-by-side relationship.
  • the feeder 2 directs the aligned nails 11 to a track assembly 3 which is downwardly inclined and which has narrow internal dimensions such that the nails descend in line side-by-side, and come together near the outlet of the track in a stepped configuration. That is, a portion of the top of each head underlies a portion of the lower surface of the adjacent nail head.
  • the collating apparatus comprising feeder 2 and track assembly 3 is well known and may be any one of a number of those commercially available; consequently, further detailed description is not necessary.
  • conveyor assembly 4 continuously accepting nails therefrom.
  • the nails are deposited from the track assembly upon conveyor assembly 4 in a side-by-side parallel relationship, and with heads 15 in stepped relationship to define the horizontal nail array 10. Since the chord section of each head abuts the shank of the adjacent heads, gaps 13 between adjacent one of the shanks 12 of the array are defined, and match the spacing of the chord from its shank. Such gaps are thus uniform in width and preferably are a small fraction of the diameter of the shanks; the relative size of the gaps has been exaggerated in FIGS. 1 and 2 for clarity.
  • the parallel side-by-side nail array relationship, together with the spacing of gaps 13, is maintained as the array is moved along because of the construction of conveyor 4.
  • the nail shanks are supported on conveyor straps and 6, which are adjacent each other and parallel, with a spacing therebetween less than the length of the nail shanks, and are driven synchronously with each other.
  • the straps 5 and 6 are provided with notches 7, which are regularly spaced by an amount matching that of the gaps l3 and which are generally semicircular and of a diameter slightly larger than the shanks 12.
  • the conveyor straps 5 and 6 are relatively narrow and provide little obstruction on the lower side of the nail array, so that access to both upper and lower sides of nail array is allowed.
  • conveyor straps 5 and 6 Supporting the conveyor straps 5 and 6 are respective pairs of identical sprocket wheels 8 and 8a, and 9 and 90, together with respective vertical drive shafts extending transversely to the direction of the straps.
  • the conveyor straps 5 and 6 are looped at one end about sprockets 8 and 8a respectively, which are located adjacent track assembly 3 and feeder 2, while at the opposite end, the straps 5 and 6 are looped about sprockets 9 and 9a respectively.
  • the conveyor straps are driven by means of drive shafts 17a and 17b mounting sprockets 8 and 8a respectively.
  • Drive shafts- 17a and 1711 also carry respectively a pair of identical engaged spur gears 19a and 19b, and shaft 17b is connected at one end through transmission 21 to motor 25.
  • motor 25 drives strap 6, and through spur gears 19a and 19b, also drives strap 5 synchronously therewith.
  • FIG. 2 shows stations III to VII in greater detail.
  • the array 10 Prior to arriving at station III, the array 10 is pre-heated to approximately 400 to 600F. by electric infra-red radiation heaters, one of which is shown schematically at 16.
  • the array 10 of nails moves beyond heater 16 to station Ill, where a rotary power tape feed device 18 directs the strip 14 of plastic tape upon the underside of the moving nail array 10, with the strip being applied generally midway ofthe nail shanks l2 and transversely to the axes of the shanks (typically at the aforementioned 60 angle) and along the direction of movement of the array.
  • the thickness of the strip 14 preferably but not necessarily is related to that of gaps 13 so that the strip is substantially half as thick as one of gaps 13.
  • tape strip 14 initially lies along the tangents of the nail shanks and immediately begins to adhere to the heated nails at its tangent point of contact therewith, since the tape has thermoplastic and adhesive qualities.
  • One example of such tape which has been found to be particularly useful with steel nails, since it adheres strongly to metal, is of an ethylenepropylene terpolymer material, manufactured 'by the Standard Oil Comapny of New Jersey, and is 0.008 inch thick and threefourths inch wide.
  • the array Immediately upon application of lower strip 14 to the underside of the array, the array arrives at station IV, downstream of feed device 18, under a vacuum funnel 20 and over a low pressure hot air blower 22, which applies a positive adhering force to strip 14 and gradually urges the tape strip 14 more completely around the nail shanks 12.
  • Blower 22 is positioned just below the conveyor 4 and the conveyed nail array and immediately adjacent the output side of tape feed device 18.
  • the blower is provided with a heating element 24 preferably heating the air therein to 350F.
  • Nozzle 23 has an enlarged width that encompasses a plurality of nails simultaneously, so that each nail shank spends a relatively large time in transit over the blower to allow the strip to be softened and gradually formed about the shanks 12.
  • Vacuum funnel 20 placed directly over the conveyor 4 and nail array 10 to cooperate with blower 22, is even more extensive, in that it extends beyond the nozzle 23 of blower 22 on both sides thereof and also partially overhangs tape feed device 18.
  • the combined action of vacuum funnel 20 and blower 22 is sufficient both to retain the tape strip against the nail array and to begin the formation of the strip about the shanks and therefore the pre-heating of the nails is not essential. This is particularly so in the case of tape with superior adhesive qualities.
  • the tape strip 14 almost immediately begins to be deformed upwardly into gaps 13 between the shanks, and into more complete contact with the shank periphery under the combined influence of the upward force exerted by the air from blower 23, the heat carried by such air, the heated condition of the nails themselves, and finally the upward pull exerted by the vacuum of funnel 20 on the strip 14.
  • This combination of influences gradually shapes lower strip 14 to impart a marked corrugated appearance.
  • blower 26 As the nail array 10 with strip 14 is conveyed beyond blower 23 and passes out from vacuum funnel 20, it passes over a high pressure and high velocity blower 26 provided with a tapered narrow nozzle jet 27, a heating element 30, and an air supply regulator 31. Blower 26 is positioned immediately below the conveyed array and to one side of blower 22 just beyond funnel 20. The blower 26 directs a comparatively narrow stream of heated air, preferably at 560 F. and at a high pressure, preferably 10 inches of mercury, upwardly against the tape strip 14, to insure that it is forced well within gaps 13.
  • the partially-enveloped nail strip is next conveyed to station V where a power tape feed device 32 similar to device 18 now dispenses a tape strip 34 similar to strip 14.
  • Tape strip 34 is directed by feed device 32 upon the upper side of nail array generally midway of the nail shanks 12 along the direction of travel of the array 10, and in registration with the lower tape strip 14.
  • a blower 36 similar to blower 22, is positioned above the conveying array and immediately adjacent the output side of tape feed device 32.
  • the blower also includes a heating device 38 that operates at a low pressure and about 350 F., which is a temperature similar to that of blower 22 to form the tape strip 34 into a corrugated form about the upper half of the circumference of nail shanks 12 as they pass under blower 36.
  • the nozzle 40 of the blower is relatively wide so as to encompass simultaneously a plurality of nail shanks, so that each nail shank spends a relatively large time interval in transit under blower 36 to allow the strip 34 to be softened and gradually formed about the nail shanks 12 under the influence of the emerging heated air.
  • blower 36 As the nails emerge from beneath blower 36, they are brought under the influence of two high velocity and pressure heated-air blowers 42 and 44 serially disposed adjacent blower 36 above the conveyed array. Both are similar to high-pressure blower 26, and include respective tapered narrow jet nozzles 45 and 46 directing a narrow high pressure stream of air against upper tape strip 34. Both units include respective air supply regulators 48 and 50 and preferably operate at a pressure of [0 inches of mercury. Blower 42 includes a heating element 52 which heats its output air preferably to about 350 F., and blower 44 includes a heating element 54 which heats itsoutput air preferably to a temperature of about 560 F. The effect of the last two high-pressure air streams acting downwardly on the strip 34 is to complete the shaping of the upper strip 34 about a substantial fraction of the upper half of the nail shank peripheries.
  • the heated air stream from blower 42 completes the forming of strip 34 around the upper half of the nail shank peripheries begun by blower 36.
  • the heated air stream from blower 44 insures that strip 34 has been heated and urged downwardly sufficiently into gaps 13 between the shanks.
  • a generally V- shaped fold is thereby defined in the upper tape strip 34 between adjacent pairs of nail shanks and extending inwardly into each gap, in opposed relationship to the fold in the lower strip 14, but spaced therefrom. This completes the formation about the nail array 10 of a unitary carrier body 56.
  • the air pressure, size, numbers and location of the blowers and the operating temperatures, or any of these factors, may be adjusted to accommodate different plastic materials or produce varying degrees of corrugations in the tape strips.
  • the plastic material may be melted or flowed into gaps 13. If desired, a lesser degree of folding and less tape material may be forced within gaps 13. Conversely, even greater amounts of tape material may be forced within gaps l3, and tapes l4 and 34 may even be forced into fusing contact therewithin.
  • L. S. Shelton for Fastener Strip it has been found that the V-shaped fold within the gaps 13 is desirable in order to provide sites promoting clean shearing of individual fasteners together with associated tape material from the remainder of the nail strip.
  • the now-completed nail strip is then moved to station VII and over a cooling blower 58 which causes the carrier body about each of the shanks to fully set, in
  • a cut-off blade 60 positioned vertically over the emerging nail strip by a solenoid 62, which operates upon command to drive the cut-off blade 60 downwardly into one of the gaps l3 to cut the strip/into convenient lengths or sticks, such as is illustrated in FIG. 3.
  • the finished sticks are then dropped off the end of conveyor assembly 4 upon a conventional conveyor 65. which includes a horizontal belt 67, a drive roller and shaft 69, and a belt drive 72 by which motor 74 drives the roller 69 and thereby the belt. in this manner. as each finished stick emerges at the outlet end of conveyor 4, it is moved away to a storage or receiving area in continuous fashion.
  • a conventional conveyor 65 which includes a horizontal belt 67, a drive roller and shaft 69, and a belt drive 72 by which motor 74 drives the roller 69 and thereby the belt.
  • the invention is not confined to use with modified nails, but may instead also utilize full-headed common nails, when provided with an appropriate collating apparatus at station I.
  • the spacing of the gaps between adjacent shanks is not necessarily a small fraction of the diameter of the shanks, and indeed must be much larger if the invention is used with full-headed nails.
  • the same conveyor assembly may be used, except that the notches in the conveyor straps are spaced farther apart to define a wider spacing, or any other conveyor assembly may be used which allows access to opposite sides of the nail array and maintains the nail shanks in spaced relationship.
  • either the upper or lower tape strips could be of a greater width than the opposite tape strip.
  • the plastic tape has both adhesive and thermoplastic qualities, either the upper or the lower tape could well be eliminated completely, and the invention would still form an array of nails into a completed nail strip.
  • the array instead of the nail array being conveyed, the array may be kept stationary on a suitable jig or support which maintains the nails in spaced relationship, while the tape dispensing means, and the various air blowers and vacuum fun nel are instead moved with respect to the nail array.
  • the apparatus is capable of substantially continuous operation, requiring only supplies of plastic tape, nails,
  • the process does not give off fumes or other toxic substances which might be harmful to the personnel operating the equipment as well as the environment as might be the case with adhesive systems using solvent.
  • the great advantage of the invention is that at no point is the plastic strip contacted by anything other than air jets, once it has been deposited on the nail array, so that all the problems of jamming and adherence of material to mechanical parts of the apparatus types usually used in the manufacture of nail strips similar to that contemplated herein, are avoided.
  • the uniformity of the tape thickness about each shank consequently is at an optimum level; also, a minimum of cooling steps are required.
  • the invention thus radically simplifies the manufacture of nail strips, and makes possible an increased volume of production, while improving reliability of the quality of the finished product.
