Definitions

  • the present invention relates to an apparatus for assembling a pair of fastener elements of a garmentfastener, such as a snap fastener, a button or an ornament, with or without a garment fabric disposed between the two fastener elements.
  • the preamble of claim 1 is based on US-A-4 376 504.
  • a clamp assembly is vertically movably mounted on an upper portion of the die and includes a pair of clamp jaws to hold the corresponding fastener element in place on the upper end of the die.
  • the clamp jaws are pivotally supported by a support block slidably mounted on the die and normally urged upwardly by a first spring ; each clamp jaw is normally urged by a second spring against the die and has a slant undersurface engageable with the fastener element when the support block is in its upper position.
  • Atthe lower end ofthe stroke of the upper unit it depresses the support block against the bias of the first spring, causing the opposed clamp jaws to be moved angularly away from each other against the bias of the second springs to release the fastener element.
  • the support block along with the clamp jaws returns to its original or upper position under the bias of the first spring.
  • the opposed clamp jaws again hold the fastener element (having been joined with its companion fastener element) against the upper end of the die under the bias ofthe second springs, causing non-easy removal of the joined fastener element pair from the lower unit.
  • an apparatus for assembling a pair of fastener elements of a garment fastener comprising: a frame; a stationary die supported by said frame; a plunger reciprocably supported by said frame and having a punch movable, in response to reciprocating movement of said plunger, toward and away from said die to join the two fastener elements together; a punch clamp assembly carried by said punch for holding the corresponding one of the fastener elements to be joined together, characterized in that it further comprises a die clamp assembly carried by said die (10) for holding the other one of the fastener elements, said die clamp assembly including (a) a support block slidably mounted on said die and movable, in response to the reciprocating movement of said plunger, between an upper position and a lower position, (b) a first spring normally urging said support block toward said upper position, (c) a pair of clamp jaws pivotally mounted on said support block and pivotally movable, in response to vertical movement of said support block, toward and away from each other for holding
  • the present invention seeks to provide a fastener-assembling apparatus in which a pair of clamp jaws holds one of a pair of fastener elements in place on a diewhen a punch is lowered toward the die and in which the opposed clamp jaws do not hold such one fastener element against the die when the punch is retracted from the die after the two fastener elements have been joined together as compressed between the die and the punch.
  • Figure 1 shows an apparatus for attaching a button A (one of a pair of fastener elements) with a tack B (the other fastener element) onto a garment fabric C ( Figures 5A, 5B, 5C).
  • the apparatus generally comprises a lower or die unit 1 and an upper or punch unit 2, both supported by a frame (not shown) in opposite relation to each other.
  • the button A has a head A1, and a shank A2 projecting centrally therefrom, while the tack B has a head B1 and a spike B2 projecting centrally therefrom.
  • the lower unit 1 includes a base 3 fixedly supported by a frame (not shown), and a stationary die 10 having a lower end portion fitted in a first vertical bore 14 in the base 3 and non-rotatably fastened to the base 3 by means of a screw 17 ( Figure 2).
  • the screw 17, when fastened, extends through the base 3, a washer 16 and a rubber ring 15 and then threadedly extends into the lower end of the die 10.
  • the die 10 has in its upper end surface a recess 11 for receiving the head A1 of the button A with the shank A2 directed upwardly.
  • the die 10 has on its upper peripheral portion a pair of diametrically opposed slant surfaces 18, 18 contiguous to the upper end of the die 10 so that a segmental portion of the button head A1 project from the respective slant surface 18 of the die 10 (for a purpose described below) when the button A is placed concentrically on the upper end of the die 10.
  • Each of the slant surfaces 18 is flat throughout its entire area.
  • the lower unit 1 further comprises a first clamp assembly 12 for releasably holding the button A on the upper end of the die 10.
  • the first clamp assembly 12 includes a support block 21 having a second vertical bore 20 and slidably mounted on the die 10.
  • the support block 21 has a pair of opposed first and second flanges 25, 26 between which a pair of clamp jaws 22, 22 is disposed, each clamp jaw 22 having sandwiched between one first flange half 25a and one second flange half 26b and being pivotally mounted thereon by a pin 23.
  • Each clamp jaw 22 is normally urged to pivot toward the support block 21 by means of a torsion spring 24 mounted around the pin 23.
  • Each clamp jaw 22 is of a generally inverted L-shape having a base portion 30 extending along a side surface of the support block 21, a distal end portion 29 lying over the top surface of the support block 21.
  • the distal end portion 29 of each clamp jaw 22 has a slant undersurface 31 engageable with the first head A1 of the button A when the latter is held on the die 10.
  • a compression spring 13 extends around the die 10 and is acting between the base 3 and the support block 21 to normally urge the support block 21 upwardly.
  • the upward movement of the support block 21 is restricted by a stop 28 extending through a horizontal hole 27 in the longitudinal groove 19 in the peripheral surface of the die 10.
  • the upper unit 2 includes a support 4 integral with the non-illustrated frame and having a third vertical bore 45, and a plunger 5 of circular cross section reciproc- able within the third vertical bore 45 in the support 4.
  • the plunger 5 is operatively connected at its upper end to a suitable drive means, such as an electric motor or a fluid-pressure actuator, for vertical reciprocating movements toward and away from the lower unit 1.
  • a suitable drive means such as an electric motor or a fluid-pressure actuator
  • the plunger 5 has an integral head 5a of circular cross section extending coaxially with the plunger 5, the diameter of the head 5a being smaller than the diameter of the plunger 5.
  • An upper holder 40 has a cylindrical portion 46 vertically movably received in the third vertical bore 45 of the support 4, and a cubic portion 47 disposed adjacent to the lower end of the support 4 and integral with the cylindrical portion 46.
  • a punch 6 is secured to the plunger head 5a by means of a horizontal pin 7 extending through the punch 6, the plunger head 5a and a bush 5b and having opposite ends slidably received in a pair of longitudinal slots (not shown) in the cylindrical portion 46.
  • a lower holder 41 is attached to the underside of the cubic portion 47 of the upper holder 40 by means of screws (not shown), and has a fourth vertical bore 49 axially alined with the third vertical bore 48 in the upper holder 40, there being defined between the upper and lower holders 40, 41 a pair of opposed horizontal guide through-holes 50, 50 each communicating at its inner end with the third and fourth vertical bores 48, 49. Also defined between the upper and lower holders 40, 41 is an opening 60 of generally T-shaped cross section extending perpendicularly to the guide through-holes 50, 50 and communicating with the third and fourth vertical bores 48, 49 through which openings the tack B to be joined with the bottom A is introduced.
  • the upper unit 2 further includes a second clamp assembly for holding the tack B, with the spike B2 directed downwardly, at the joint of the upper and lower holders 40,41.
  • the second clamp assembly comprises a pair of cooperative clamping fingers 42, 42 slidably received in the respective guide through-holes 50, 50, a pair of springs 43, 43 normally urging the clamping fingers 42, 42 inwardly toward each other to clamp the tack B, and a push member 44 disposed opposite to the openings 60, and slidable perpendicularly to the clamping fingers 42, 42 to push the latter outwardly away from each other and, at the same time, to push the tack B out of the upper unit 2 through the opening 60.
  • each clamping finger 42 has an arcuate surface of a curvature substantially equal to the curvature of a peripheral edge of the tack B, there being in and along the arcuate surface a groove 51 of an arcuate cross section for receiving a portion of the peripheral edge of the tack B.
  • the push member 44 is of an inverted L shape having a horizontal wall 53 and a vertical wall 54 extending downwardly from one or outer end of the horizontal wall 53.
  • the push member 44 is slidably supported by a horizontal pin 56 mounted on the lower holder 41 and extending through the vertical wall 53 of the push member 44.
  • a compression spring 57 ( Figure 4) is mounted around the horizontal pin 56 between the lower holder 41 and the vertical wall 53 of the push member 44 to normally bias the latter outwardly (leftwardly in Figure 4). This outward movement of the push member 44 is limited by a stop ring 58.
  • the other or inner end of the push member 44 has a pair of opposite sloping surfaces 55, 55 ( Figure 3).
  • the button A is placed upside down in the lower unit 1 with the support block 21 in raised position in which the pair of clamp jaws 22, 22 resiliently holds the head A1 of the button A against the upper end of the stationary die 10.
  • the tack A is placed in the upper unit 2 with the head B1 clamped by the pair of clamping fingers 42, 42.
  • a garment fabric C is then placed over the top surfaces of the flanges 25, 26 of the support block 21.
  • the plunger 5 starts to move downwardly toward the die 10.
  • the upper and lower holders 40, 41 move along with the plunger 5 until the bottom surface of the lower holder 41 contacts the garment fabric C, as shown in Figure 5A.
  • the plunger 5 Upon completion of attachment of the button A, the plunger 5 is actuated to retract, along with the punch 6 and the upper and lower holders 40, 41 and the clamp fingers 42, 42, from the lower unit 1, allowing the support block 21 to return to its original or upper position under the bias of the spring 13.
  • the distal end of each clamp jaw 22 is urged against the respective slant surface 18 of the die 10 and slides upwardly on that slant surface 18. Since a segmental portion of the button head A1 projects from the respective slant surface 18 of the die 10, the distal end of each clamp jaw 22 finally hits the projected segmental portion of the button head A1 to push the joined button A and tack B away from the die 10, as shown in Figure 5C.
