Definitions

  • This invention relates to fastener carrier tape and particularly, but not exclusively, the discharge of fasteners from such a carrier tape into a delivery chamber or tube of an application machine which will apply them to work-pieces, typically using a fastener driving plungerwhich discharges a fastenerfrom the tape and continues to drive the fastener through the delivery tube.
  • Such a delivery chamber allows fastener application where workpiece access is restricted.
  • fasteners As fasteners are released from the carrier tape, they need to be guided precisely into a delivery chamber, otherwise they may lose their orientation.
  • fastener is employed herein to embrace a disparate variety of elements for joining one component to another.
  • the invention is of particular relevance to rivets, such as hollow part tubular self-piercing rivets, with a shank and relatively enlarged head.
  • Fasteners such as rivets, whose length is short in comparison with girth present special feeding control problems because of their inherent tendency to tumble.
  • the shank of the fastener is fed or loaded, as a tight or snug fit, into a pre-pierced retention hole of complementary profile in the tape and at the point of application the head of the fastener is forced through the hole.
  • the consequent tape fragments may impede the feeding of the fastener into the mouth of a delivery tube, or may disturb the fastener orientation upon discharge from the tape.
  • the diameter of the mouth of the chamber has to be increased to an extent that the mouth section can no longer be fully effective in guiding the fastener into the chamber.
  • the tape can be weakened by completely or partially cutting or shearing it at selected local points around the circumference - thereby pre-determining the manner of tape deformation and splitting, as the head of the fastener passes through it.
  • the tape material is partially cut or sheared in four lines radiating out, quadrantally at 90° to each other, from the fastener retaining holes, it can be ensured that the tape will split along these lines, as the head of the fastener passes through the tape.
  • Such slots can very conveniently be formed integrally with each retention hole profile, by means of a simple punch and die - and the geometry of the star-shaped overall retention hole so formed can be very consistently controlled in manufacture.
  • slots are slots with a smooth radius at their outward ends, it is possible to avoid the local stress concentrations which can lead to splitting of the tape as the head of the fastener passes through.
  • Maintaining control of the slot geometry provides a means of control of the geometry of the material flaps between the slots - and of thereby ensuring that, as these flaps flex to allow the head of the fastener to pass through the tape, they collectively provide a guidance funnel.
  • control of the positioning of the fastener as it passes through the tape can be preserved - without undue risk of the tape becoming trapped between the head of the fastener and a delivery chamber mouth.
  • Both the cut slit and cut-out slot means of locally weakening the tape are particularly beneficial when used in conjunction with a tubular delivery chamber also devised by the Applicants - the subject of separate application for patent protection - and which deploys an internal guide to form a constriction movable co-operatively in conjunction with fastener movement through the tube.
  • the depending tape flaps formed upon fastener discharge may co-operate with such a delivery tube internal guide.
  • Profiled fastener retention hole cut-outs can also be used in conjunction with tape indexing or positioning slots as described elsewhere herein.
  • positioning, or position indexing, slots are provided in the tape adjacent to the pierced holes into which the fasteners will be placed.
  • the travel of the tape can, by the use of the positioning slots, be arrested by mechanical and/or optical means at the precise position required to position the next fastener centrally within the delivery chamber.
  • carrier tape and attendant fastener retention hole alignment can be achieved by positioning a light source on one side of the tape in line with the slots and a receiver on the other side of the tape - so that a light signal can be received when a slot either arrives at or departs from the light beam.
  • a fastener carrier tape for carrying a linear succession of discrete fasteners, each with a shank and relatively enlarged head, in a corresponding succession of fastener shank retention holes, each configured to provide the tape with a pre-determined mode of local deformation, upon passage of a fastener head there-through, in order to preserve a required fastener orientation until discharge from the tape.
  • a fastener carrier tape for use in conjunction with a fastener application machine, including a fastener driving plunger, with a fastener contact driver head, and a delivery tube, for presenting a fastener to a remote workpiece, the driving plunger being operative to drive a fastener from the tape and through the delivery tube, until the fastener is driven into the workpiece thereby; the tape carrying a linear succession of discrete fasteners, each with a shank and relatively enlarged head, in a corresponding succession of fastener shank retention holes, each configured to provide the tape with a pre- determined mode of local tape deformation, upon passage of a fastener head there-through, in order to preserve a required fastener orientation until a controlled discharge from the tape.
  • the retention hole profiles may incorporate supplementary peripheral cut-outs to create depending flaps upon local tape deformation, which flaps collectively form a fastener delivery or discharge guidance funnel, to co-operatively align and inter-nest with the mouth of a delivery tube, for presenting a fastener to a workpiece, and whereby fastener orientation is preserved until discharge from the tape, whereupon it is brought under the control of the delivery tube.
  • the individual fastener shank retention holes may comprise star-shaped cut-outs.
  • the fastener shank retention holes are configured with supplementary slits or cuts, partially or completely through the body of the tape material, to create depending flaps upon local tape deformation, which flaps collectively form a fastener delivery or discharge guidance funnel, to co-operatively align and inter-nest with the mouth of a delivery tube, for presenting a fastener to a workpiece, and whereby fastener orientation is preserved until discharge from the tape, whereupon it is brought under the control of the delivery tube.
  • the tape may incorporate a linear succession of position indexing and drive holes, one or more for each fastener location, and co-operatively disposed with respect to said fastener retention holes, whereby fasteners entrained in the tape may be brought precisely into alignment with a desired discharge position, such as the mouth of a delivery tube for presenting fasteners to a workpiece.
  • the tape may be adapted to carry hollow, part tubular, self-piercing rivets.
  • Yet another aspect of the invention provides a fastener application machine utilising as a source of fastener supply, a fastener carrier tape as set out in the immediately preceding paragraphs.
  • a fastener application machine utilising as a source of fastener supply, a fastener carrier tape as set out in the immediately preceding paragraphs.
  • Such a machine may incorporate a tape position indexing mechanism and an optical beam tape alignment sensor for monitoring index hole position.
  • a flexible carrier tape 1 incorporates a centrally-disposed row of fastener retention holes 5 in a linear succession.
  • the tape 1 is partially loaded with fasteners 4 with a shank 15 and relatively enlarged head 16, as depicted in Figure 3.
  • each fastener retention hole 5 is profiled as a generally circular central hole 2 with outwardly-tapered, radial slots or cut-outs 6, in a generally star-shaped array, to facilitate insertion and retention of a fastener 4.
  • An alternative retention hole configuration relies upon cut, split or shear lines partially or completely through the tape thickness. Indeed cuts or slits may replace or supplement cut-outs, ie wholesale local material removal.
  • hole profile may extend marginally beyond the installed fastener head circumference.
  • a headed fastener 4 is depicted passing through flexible tape 1 into the funnel- shaped mouth 17 of a delivery tube 7 for directing fasteners to a remote workpiece, using an unshown driving plunger which displaces fasteners from the tape 1 and continues down the tube until the workpiece is contacted by the fastener, whereupon the fastener is driven into position.
  • depending guidance flaps 19 are formed which co-operate as a funnel with the delivery tube mouth 17 - thereby preserving a desired fastener orientation until and upon tape discharge.
  • a carrier tape 1 similar to that of Figure 1, incorporates supplementary tape position indexing holes 8, to facilitate precise control of tape progress through a fastener application machine for which the tape forms a fastener supply.
  • a carrier tape otherwise of the kind shown in figure 1 has two rows of position indexing elongate slots 3a and 3b, disposed atthe opposite tape side edges.
  • a carrier tape 40 has a central row of fastener retention holes 31 and a single row of corresponding position indexing slots 33 configured for optical alignment sensing.
  • indexing slots 33 are co-operatively disposed with respect to a pair of aligned light sources 34 mounted on one side of the carrier tape 40 and projecting parallel individual light beams 41 into light receivers or sensors 32 positioned on the opposite side of the tape.
  • the light sources 34 are positioned so that the light beams 41 pass through the extreme ends of individual positioning slots 33, so that the position of the slots 33 - and thus of the corresponding fastener retention holes 31 - can be precisely determined.
  • an alternative configuration of carrier tape relies upon two precisely spaced, pierced position indexing holes, in place of elongate slots.
  • FIG 9 shows the tape of Figure 15 used in conjunction with a pair of light sources and sensors such as in the arrangement of Figures 13 and 14.
