Definitions

  • This invention relates to footwear-making equipment, and more particularly, to a device for stretching uppers over a last preparatory to gluing the edge of the uppers to a supporting insole which has been secured under the last.
  • the basic steps involved in the process consists of placing the uppers onto a last under which a supporting insole has been secured, clamping the edges of the uppers in a multiplicity of grippers mounted all around the last, stretching the uppers over the last by a relative movement of the grippers and the last, locking the uppers to the last by means of a crescent-shaped member adapted to apply a pressure to the last edge, gradually releasing the grippers from the uppers, tucking the uppers edge under the last by means of two movable shaped plates, and adhering the uppers edge to the insole using a glue which has been coated over the two parts to be joined.
  • the grippers should be arranged around the last such that their clamping points, specifically the sections which border the respective clamping points, are aligned to one another a predetermined distance away from the last to follow the contour of the latter, and such that their pull is applied evenly all around the edge of the uppers.
  • adjusters are usually provided which enable a gripper to be moved toward and away from the last, sideways toward and away from adjacent grippers, and rotated about its axis to evenly merge with one another the clamping points of adjacent grippers.
  • a gripper generally designated 10 with its supporting and driving members.
  • the gripper has a box-type body 11 which is attached by two arms 13 to a rod 12 into a four-bar linkage.
  • An electric motor 14 is mounted to the body 11 for oscillation about a pivot pin 15 and is coupled to the four-bar linkage by conventional means (not shown) for the purpose to shift the gripper 10 along a substantially parallel direction to the longitudinal axis of the rod 12, upwards as viewed in the drawing.
  • the gripper has two jaws 16 connected to the body 11 for pivotal movement relatively to each other, and an air-operated cylinder 17 attached to the body 11.
  • the cylinder 17 is coupled to the gripper jaws by conventional means for the purpose, of which only one tie rod 19 is partly shown in the drawing figure, to operate the gripper by opening or closing its jaws 16.
  • the rod 12 has an element 12a attached rigidly thereto which is constructed and functions as a chain link and is mounted to a linkage element or connecting rod 20 for pivotal movement about its longitudinal axis a-a within a cylindrical socket 21 ( Figures 3 and 4) of the connecting rod 20.
  • the latter has two lugs 20a laid opposite each other into a yoke configuration and being passed through by respective coaxial bores 22 through which a pin 23 extends.
  • FIG. 3 and 4 Shown schematically in Figures 3 and 4 is a supporting and driving structure for a multiplicity of grippers 10.
  • the grippers nine in number, are only represented by their incomplete outlines.
  • Shown in the Figures are the connecting rods 20 and chain links 12a, the latter being connected pivotally together by pins 24.
  • One of the grippers, the central or apical one shown at 10a, is made narrower than the others, carries no linkage element 20, and has its rod fastened rigidly to the bed by suitable means, not shown.
  • the structure comprises a rigid supporting part 25 in the form of a cylinder, with a portion of its surface removed and is fastened to the machine bed.
  • this cylindrical part 25 is represented by just two wall portions. It should be understood, however, that the two portions are joined together at the top of the Figure and extended into the bottom part thereof to leave a passage for accessing the center of the structure where the last is accommodated on which the uppers would be stretched.
  • the last and respective supporting and driving means have not been shown because conventional.
  • the structure further comprises two thick supporting and guiding plates, shown at 26, which are also fastened rigidly to the machine bed by suitable means, not shown, and extend into the cylindrical part 25 in a common plane perpendicular to the cylinder axis, with a spacing therebetween.
  • These plates 26 have notches 27 being open to the machine center and extending radially outwards. Through the thickness of the plates 26 there are provided bores 29 which extend from the bottoms of the notches 27 to the outward edges of the plates.
  • Each notch 27 provides a runway for a slide 28 connected pivotally to one of the connecting rods 20 by a respective pin 23, only shown in Figure 1.
  • Each slide 28 has a longitudinal threaded bore 28a ( Figure 1) into which an oppositely threaded shaft 30 engages correspondingly in helical fit relationship. The latter extends into the bore 29 between its respective slide 28 and a bearing coupling 31 mounted on the cylindrical part 25.
  • the shafts 30 are each driven rotatively by a motor 33 secured on the cylindrical part 25.
  • the motors 33 are operated in a co-ordinate fashion until the various grippers have been moved into a selected clamping pattern.
  • this setting would be performed by an electronic control unit, known per se, so programmed as to enable a series of adjustments for moving the grippers into the best clamping pattern for a given footwear article design to be assembled.
  • the position of each gripper must be known each time.
  • position sensors may be employed which can be coupled either to the slides 28 or the setting motors 33 and supply each time acknowledge signals of the positions of the individual grippers to the electronic control unit, or step motors may be used whose angular settings would be known at all times.
  • the device of this invention enables optimum setting of the grippers for any design, shape, and size of a footwear article to be assembled.
  • the various patterns stored in the unit can be retrieved and changed as required, thereby the gripper positioning can be adjusted to fit any shapes, sizes, or sides (right or left) of footwear articles to be assembled, quite rapidly and accurately on all occasions, thus significantly expanding the machine versatility and production over prior art machines.
