Definitions

  • the invention refers to an automatic device for insoles, applicable to footwear lasts, consisting of a movable rod, which slides within a tubular body where an elastic return member is housed, with numerous pointed prongs aligned with each other on one end.
  • One pair of the said rods is applied to each footwear last so that the prongs of one of them slightly protrude from the bottom of the last corresponding to and in the direct­ion of the toe, and the prongs of the second slightly pro­trude from the said bottom, but corresponding to and in the direction of the heel.
  • one of the first processing phases consists in fixing the insoles to the lasts to allow the successive pre-assembly-assembly operations of the uppers.
  • the preliminary, but fundamental operation is presently performed manually.
  • the workers assigned to this operation must rest the corresponding insole on each over-turned last and fix it using numerous small nails. Once all the assembly operations of the uppers and the carding of their bottoms in the successive operations have been completed on the last the insoles must be released by removing the nails before the sole fixing operations are carried out.
  • the nail removing operation to release the insoles also requires the manual intervention of the operators.
  • the aim of this invention is to overcome the above men­tioned manual nailing and nail-removal operations.
  • the invention as characterised by the claims, overcomes the problem by forming an automatic fixing device for insoles applicable to footwear lasts.
  • the advantages provided by this invention essentially consist in the fact that the coupling operation of the insoles to the lasts is made simple, rapid and automatic, the operation is performed mechanically with less need of labour; the connection between the insoles and lasts is sufficiently rigid as to guarantee the perfect execution of all the successive operations; separation of the last from the insoles is achieved very easily, by simply sliding off the upper; the possible minor burrs produced by the prongs on the heel when sliding-off the upper are however covered over by the finishing lining; the prongs of the toe device do not cause burrs, since their orientation corresponds to the extraction direction of the last.
  • the figures represent automatic fixing devices for insol­es, applicable to footwear lasts consisting essentially of a moving rod (1), that slides inside a tubular body (2) in which an elastic return member is housed (3) as for example, a spiral spring, with numerous prongs (4) on one end, the said prongs being pointed and aligned with one another in the form of a comb (5).
  • the other end of the rod (1) is preferably fitted with a spherical or rounded end (7), designed to support the impacts of a presser piston (8).
  • the body (2) that forms the guide in which the rod (1) can slide longitudinally may be made in various ways.
  • it consists of a simple length of tube and a return spring (3) is interposed between its ends (9) and the rear part of the comb (5).
  • the body (2) has groov­es (10) in which small guide pins slide (11) these maintain the rod (1) and the comb (5) aligned, in accordance with the pre-established orientation.
  • the tubular guide body (2) is fitted with an internal cylindrical seat (12) in which the return spring (3) is inserted.
  • the guide grooves (10') are realised here in the front part of the tubular body (2) and alignment is maintained via the sliding of the said comb (5) therein.
  • the automatic fixing devices made in accordance with that illustrated previously, or according to possible variants are successively forced inside the holes (14) made in the lasts (13), until the pointed ends of the prongs (4) kept in tension by the return spring (3) are made to protrude from their base (15).
  • the tubular body (2) may also be omitted, using the holes (14') made on the lasts (fig.4) directly as a guide for the rods (1).
  • the orientation of the prongs (4) i.e. of the combs (5) is substantially parallel to the base plane (15) of the last (13) and transverse to it.
  • the last (13) is turned over and the insole (16) is placed on top of the last base (15); in this arrangement the prongs (4) are normally pushed in­side the tubular bodies (2), or (14').
  • the overturned last (13) is then fitted onto the rear fix­ed pin (17) and on an adjustable front support (18), pre­ferably made of an elastic material, such as rubber and similar products.
  • the insole (16) is successively pressed against the base (15) of the last (13) by a pair of upper pads (22) that oscillate about fulcrums (23) and are held by supports (24) the position and distance of which are adjusted by sliding along the guides (25).
  • the adjustable front buffer (18) is also held by a support (29) that can slide along the guide (19).
  • the supports (24) and (29) are fitted with fixing screws (26) and (20).
  • the upper guides (25) in turn oscillate about an upper fulcrum (30) placed on the upper pressor piston (21). Adjustment of the buffer (18) and of the pads (22) and their oscillation about the fulcrums (23) and (30) allow a perfect, rapid and simple fixing of the last (13) against the insole (16), irrespective of their shape and size.
  • the pressor piston, or hammer (8) is actioned, which by forcing against the spherical, or round­ed ends (7) aligned thereto, exerts a force on the rods (1) causing them to slide towards the base (15) of the last (13). Thanks to the said sliding action, the prongs (4) of the combs (5) which had been pressed inside the last (13) by the pressure exerted by the positioning of the insole (16), but which however had remained in contact with it thanks to the effect of the return spring (3) become embedded in the surface of the said insole.
  • the upper pads (22) rise up and their last (13) can be withdrawn, together with its relative insole (16) fixed to it by the protruding prongs (4), embedded therein, in correspondance to the toe and the heel.
  • the automatic fixing device significantly simplifies the operation of applying insoles and makes it more rapid since it is performed automatically, without requiring much labour.
  • the structural simplicity of the device permits its applic­ation rapidly and economically on any type of last (13) whether it is a new construction, or one existing already.
  • the pressor piston, or hammer (8) is preferably realised by a pneumatic, or hydraulic piston on the stem of which a round body, or roller is applied.
  • the hammer (8) and the ends ( 7 ) against which it rests, have rounded shapes to allow easy distribution of the force in the inclined directions of the rods (1).
  • the insole (16) will be released from the last (13) at the very moment that it will be slipped off the upper, not illustrated, which at that point will already be fixed to the insole. Due to the inclination of the prongs (4) corresponding to the heel (28) during extraction of the last (13), slight burrs are produced in correspondence to the point of each prong, which however are covered over by the finish lining.
  • the prongs (4) of the device applied on the toe (27) of last (13) however do not cause any burrs, since their orient­ation corresponds to the direction of extraction of the last from the upper.
